Android upgrades promised
Not stated by Samsung›3 Android upgrades
What does this mean?
How many new versions of Android (with the matching One UI) Samsung promised this phone would get after the one it came with.
Samsung promises a number of versions rather than a date. Each upgrade brings new features; security updates are a separate promise, in the row above.
Matters most if: You want the newest Android features for years to come.
Android at launch
Android 7.0 (Nougat)›Android 10
What does this mean?
The version of Android, Google's phone software, that was installed when the phone first came out. Samsung adds its own design and features on top, called One UI (TouchWiz on older phones).
A Galaxy moves to newer Android versions through updates, so this shows where it started, not what it runs today.
Security updates until
No longer updated (same on both)
What does this mean?
The month Samsung's promise of security updates for this phone runs until: the date Samsung's own page gives, or worked out from the number of years Samsung announced, counted from when the phone came out.
A phone bought later or used has fewer years left. "No longer updated" means the phone is no longer on Samsung's list of phones that get security updates.
Matters most if: You plan to keep the phone for years, or you're buying one used.
Galaxy AI
No (same on both)
What does this mean?
Galaxy AI is Samsung's name for its set of AI features, such as live translation of phone calls, writing help and photo editing that fills in parts of a picture.
Samsung lists which phones get Galaxy AI, at launch or through a One UI update. Some features work on the phone itself and others use the internet; Samsung lists which is which, and availability varies by language and country.
Matters most if: You want AI features such as call translation or photo editing built into the phone.

Galaxy S8: $724.99 for the unlocked version, on sale from May 2017
What does this mean?
What Samsung charged in the US when the phone launched, for the version with the least storage, before sales tax. Phones from before about 2014 were often priced with a two-year carrier contract.
This is not what it costs today: check the used and refurbished links for current prices. If Samsung has not confirmed a price, the site shows "Price not confirmed by Samsung".
Battery1 gain · 1 unconfirmed
Battery capacity
3000 mAh›4500 mAh
What does this mean?
How much charge the battery holds, measured in mAh (milliamp-hours). Samsung lists a typical figure; we show the one Samsung gives.
A bigger number stores more energy, but how long a charge lasts also depends on the screen, the chip and which features you use.
Battery life (Samsung's figure)
Up to 17 hours of video playback›Not stated by Samsung
Samsung gives a different figure for another version: Galaxy S8, International version: Up to 16 hours of video playback.
What does this mean?
Samsung's own figure for how long a full charge lasts in one of its tests, usually hours of video playback (talk time on older phones).
It is a lab test of one activity, so real use with a mix of apps is usually shorter. Compare it only with another Samsung figure for the same test.
Matters most if: You are often away from a charger all day.
Camera6 gains · 2 changes
Rear cameras
1›3
What does this mean?
How many cameras are on the back. Each one is a separate lens for a different view: wide (the main camera), ultra wide and telephoto (zoom), depending on the model.
More cameras let you switch between a wide scene and a zoomed-in view using real lenses instead of cutting out part of the picture.
Main camera
12 MP›108 MP
Samsung gives a different figure for another version: Galaxy S8, Japan version: 12.2 MP.
What does this mean?
The resolution of the main camera's sensor in megapixels (MP), meaning millions of light-catching dots.
High-megapixel cameras usually combine neighboring dots into a smaller photo by default; you can switch to full resolution for large prints or cropping.
Matters most if: You want full-size photos for large prints or for cropping later.
Ultra wide camera
None›12 MP
What does this mean?
The resolution in megapixels (MP) of the ultra wide camera: the lens that fits the most into the frame.
Use it for group photos, rooms and landscapes when you can't step back.
Matters most if: You shoot group photos, small rooms or landscapes.
Telephoto camera
None›12 MP
What does this mean?
The resolution in megapixels (MP) of the telephoto camera: a separate zoom lens that sees far-away things as if you were closer. "None" means the phone has no telephoto camera. Some Ultra models have two.
At the telephoto's own zoom level, the photo comes from a real lens instead of a cropped, enlarged image.
Matters most if: You photograph kids' sports, concerts, pets or wildlife from a distance.
Optical zoom
None›5x optical zoom
What does this mean?
How far the telephoto lens zooms on its own compared with the main camera (1x), for example '3x optical zoom'. Where Samsung lists two telephoto lenses, the comparison uses the longer one.
At this level the lens does the zooming, so no part of the image is cut away. 'Optical quality zoom' figures some models list come from cropping a high-resolution camera, not from a lens.
Matters most if: You compare zoom between phones: compare this row, not the 'up to' figures.
Digital zoom (most)
Up to 8x›Up to 50x
What does this mean?
The farthest the camera can zoom, with software doing the work beyond what the lenses reach. Samsung calls it Space Zoom on many models.
Past the lens's own zoom, the camera enlarges part of the picture and relies on processing to keep it sharp, so the highest levels lose detail.
Matters most if: You zoom far and need the photo to show fine details.
Front camera
8 MP›10 MP
What does this mean?
The resolution in megapixels (MP) of the selfie camera on the front.
A higher number keeps more detail in selfies and video calls, but light and processing matter as much.
Video (best)
4K 30 fps›8K 24 fps
What does this mean?
The highest video quality the rear camera records. 4K and 8K describe the picture size (8K is larger), and fps (frames per second) is how many still images make up each second.
Higher settings make bigger files, so long 8K or 4K 60 fps clips fill storage quickly.
Matters most if: You film a lot.
Screen3 changes · 1 unconfirmed
Screen size
5.8 in›6.9 in
What does this mean?
The screen size, measured corner to corner (diagonally) in inches. 1 inch is 25.4 mm.
Samsung measures the screen as a full rectangle, so with rounded corners the visible area is a little smaller.
Screen type
Super AMOLED›Dynamic AMOLED 2X
What does this mean?
The type of screen, in Samsung's own words, such as Super AMOLED or Dynamic AMOLED 2X. AMOLED screens light each dot on its own, so black areas are truly black.
The name alone does not tell you how bright or sharp a screen is, so compare the brightness, resolution and refresh rate rows.
Refresh rate (most)
Not stated by Samsung›120 Hz
What does this mean?
How many times per second the screen redraws the picture, in hertz (Hz). 120 Hz means up to 120 times a second.
A higher rate makes scrolling and switching apps look smoother, and uses more battery.
Matters most if: You scroll social feeds, read long pages or play fast games.
Resolution
2960 x 1440 (Quad HD+)›3088 x 1440 (Quad HD+)
What does this mean?
How many dots (pixels) make up the screen, written as height x width, with a name such as Full HD+ or Quad HD+.
On screens of the same size, more pixels show text and photos in finer detail.
Adaptive refresh rate
Not stated by Samsung (for both)
What does this mean?
The range of refresh rates the screen moves between on its own, in Samsung's words, such as '1~120Hz'. A screen that can slow to 1 Hz saves battery on still images.
The screen speeds up for scrolling and games and slows down for reading, to balance smoothness and battery life.
Matters most if: You care about battery life as well as smooth scrolling.
Peak brightness
Not stated by Samsung (for both)
What does this mean?
The brightest the screen can get, in nits (a unit of screen brightness; higher is brighter), as Samsung measures it.
A high peak brightness makes the screen easier to see in direct sunlight. Makers measure peak brightness in different ways, so compare it only between phones from the same maker.
Matters most if: You use your phone outdoors a lot, such as for maps or photos in sunlight.
Design & buttons3 changes · 2 unconfirmed
Unlock
Fingerprint (on the back), Iris Scanner, Face Recognition›Ultrasonic Fingerprint (in the screen), Face Recognition
What does this mean?
Ways to unlock the phone with your body instead of typing a PIN: a fingerprint sensor (in the screen, the side key, the home key or on the back), face recognition, or on some older models an iris scanner.
An ultrasonic sensor in the screen reads your finger with sound waves; others use light. Where the sensor sits changes how you unlock the phone with one hand.
Weight
155 g›208 g
What does this mean?
How much the phone weighs in grams (g); about 28 g is 1 ounce.
You feel the weight most when you hold the phone up for a long time, such as reading or filming.
Size (mm)
148.9 x 68.1 x 8.0›164.8 x 77.2 x 8.1
What does this mean?
The phone's size in millimeters (mm): height x width x depth (thickness). 25.4 mm is 1 inch.
Height and width tell you whether it fits your pocket and hand; depth is how thick it is.
Materials
Corning Gorilla Glass 5 front and back›Not stated by Samsung
What does this mean?
What the outside of the phone is made of: the cover glass over the screen and back, and the frame around the edge, as Samsung lists them.
Glass names such as Corning Gorilla Glass Victus or Gorilla Armor are tougher generations of glass; a titanium or aluminum frame changes the weight and feel more than the strength in daily use.
Headphone jack
Yes›Not stated by Samsung
What does this mean?
Whether the phone has a 3.5 mm socket for wired headphones (the standard round headphone plug).
Without the jack, wired headphones need a USB-C plug or an adapter, or you use Bluetooth earbuds.
Water and dust resistance
IP68 (same on both)
What does this mean?
A standard code for how well the phone keeps out dust and water. The first digit is dust (6 means dust-tight) and the second is water (8 is the highest of the usual ratings).
Samsung tests in fresh water; salt water, pools and soapy water are not covered, and the protection can wear off over time.
Charging & connections1 gain · 3 changes · 3 unconfirmed
USB port
USB-C, USB 3.1 Gen 1›USB-C, USB 3.2
What does this mean?
The kind of USB port Samsung lists: Micro USB on older phones, USB-C on newer ones, with a USB version such as USB 2.0 or USB 3.2. It concerns moving data over a cable, such as copying files to a computer.
A higher USB version can copy files faster with a cable that supports it. Charging speed is listed separately.
Wired charging
Fast Charging›Up to 25W
What does this mean?
How fast the phone charges with a cable, in Samsung's words, such as Super Fast Charging (25W or 45W). W (watts) is how much power the charger can deliver.
The top speed needs a charger and cable that support it; recent Galaxy phones come with a cable but no charger.
Matters most if: You often need a quick top-up before heading out.
Wireless charging
Fast Wireless Charging›Up to 15W
What does this mean?
Whether and how fast the phone charges on a wireless charging pad, in Samsung's words, such as Fast Wireless Charging 2.0.
The fastest speed usually needs a matching Samsung charger. Wireless charging is slower than a cable but saves plugging in.
Wireless PowerShare
Not stated by Samsung›Yes
What does this mean?
Wireless PowerShare lets the phone wirelessly charge another device, such as Galaxy Buds or a Galaxy Watch, placed on its back.
It works with devices that charge wirelessly, and it uses the phone's own battery.
Matters most if: You carry wireless earbuds or a watch and want to top them up away from a charger.
Wi-Fi
Wi-Fi 5 (802.11ac)›Wi-Fi 6
What does this mean?
The Wi-Fi generation, such as Wi-Fi 5, Wi-Fi 6E or Wi-Fi 7. 6E and 7 can also use the 6 GHz band, which is less crowded. Older phones list only the 802.11 letters (n is Wi-Fi 4, ac is Wi-Fi 5, ax is Wi-Fi 6).
A newer generation helps only with a router that supports it, and the 6 GHz band is not allowed in every country.
Matters most if: You have, or plan to buy, a Wi-Fi 6E or Wi-Fi 7 router.
Ultra Wideband
Not stated by Samsung›Yes
What does this mean?
Ultra-Wideband (UWB) is a radio chip that measures how far away another UWB device is and in which direction. It only works with another device that also has UWB.
With a tracker tag that has UWB, such as a Galaxy SmartTag+, the phone can show distance and direction to find keys or a bag.
Matters most if: You use tracker tags to find keys or bags.
mmWave 5G
Not stated by Samsung›Yes
What does this mean?
mmWave ("millimeter wave") is a high-band type of 5G. The more common type, Sub-6, uses frequencies below 6 GHz. Usually only the US versions of Galaxy phones can use mmWave.
You need a carrier with mmWave 5G where you use the phone; the carrier's network decides which type the phone uses.
Matters most if: Your carrier offers mmWave 5G where you live or work.
Qi2 magnetic charging
Not stated by Samsung (for both)
What does this mean?
Qi2 is a wireless charging standard with magnets that hold the charger in the right spot.
Samsung says which Galaxy phones work with Qi2 chargers, and whether they need a case with magnets for the charger to snap on.
Matters most if: You want a charger or stand that snaps onto the phone.
Bluetooth
v5.0 (same on both)
What does this mean?
Bluetooth connects wireless accessories, such as earbuds and watches, to the phone. The number, such as v5.3, is the Bluetooth version.
Newer versions add features such as LE Audio, but your earbuds or watch need to support them too.
SIM
SIM card (eSIM not stated) (same on both)
Worded by this site from Samsung's eSIM and SIM card slot details; Samsung's own SIM wording for this version was not checked.
What does this mean?
Which SIM the phone takes: a SIM card from your carrier in a tray (nano SIM), an eSIM (a digital SIM built into the phone), or both. Samsung lists the combinations, such as "SIM 1 + eSIM".
Whether you can use eSIM depends on your carrier and country. Some versions of a model take two SIM cards, others one SIM card and an eSIM.
Matters most if: You travel abroad or want two phone lines on one phone.
FeliCa
Not stated by Samsung (for both)
What does this mean?
FeliCa is the contactless chip behind Osaifu-Keitai, the tap-to-pay service used in Japan for transit cards such as Suica and e-money such as WAON.
Samsung Japan lists it for the Galaxy versions sold in Japan; versions sold elsewhere do not have it.
Matters most if: You live in Japan, or want to use Suica or other Osaifu-Keitai services.
Chip & storage3 changes
Chip
Qualcomm Snapdragon 835 (MSM 8998 Octa-Core 2.35GHz Quad + 1.9GHz Quad)›7nm 64-bit Octa-Core Processor (3.0GHz max + 2.4GHz + 1.8GHz)
What does this mean?
The main processor: the part that runs apps, camera processing and on-device AI. Samsung uses its own Exynos chips in some countries and Qualcomm Snapdragon chips in others, sometimes for the same model.
Where the chip depends on the country, the page shows a switch for the versions Samsung lists. A newer phone can have an older chip, so compare the chip names rather than the year.
Matters most if: You are buying a model that was sold with two different chips.
RAM
4 GB›12 GB
What does this mean?
RAM is the phone's short-term working memory for the apps running right now, measured in GB (gigabytes).
More RAM lets more apps stay open in the background. RAM is separate from storage, which holds your apps, photos and files. On some Galaxy phones it depends on the storage size or the country.
Storage options
64 GB›128 GB, 512 GB
What does this mean?
How much space the phone has for apps, photos, videos and files, in GB (gigabytes) or TB (terabytes; 1 TB is 1,000 GB).
Each storage size is sold at its own price, and not every size is sold in every country. You get less usable space than the number shown, because some of it holds the phone's own software.
Security chip
Not stated by Samsung (for both)
What does this mean?
A separate secure processor that keeps passwords, PINs and other sensitive data apart from the rest of the phone. Samsung calls it Knox Vault.
Phones where Samsung names no security processor still have Samsung Knox security in their software; this row only shows a separate chip Samsung names.

Android upgrades promised
Not stated by Samsung›3 Android upgrades
What does this mean?
How many new versions of Android (with the matching One UI) Samsung promised this phone would get after the one it came with.
Samsung promises a number of versions rather than a date. Each upgrade brings new features; security updates are a separate promise, in the row above.
Matters most if: You want the newest Android features for years to come.
Android at launch
Android 7.0 (Nougat)›Android 10
What does this mean?
The version of Android, Google's phone software, that was installed when the phone first came out. Samsung adds its own design and features on top, called One UI (TouchWiz on older phones).
A Galaxy moves to newer Android versions through updates, so this shows where it started, not what it runs today.
Security updates until
No longer updated (same on both)
What does this mean?
The month Samsung's promise of security updates for this phone runs until: the date Samsung's own page gives, or worked out from the number of years Samsung announced, counted from when the phone came out.
A phone bought later or used has fewer years left. "No longer updated" means the phone is no longer on Samsung's list of phones that get security updates.
Matters most if: You plan to keep the phone for years, or you're buying one used.
Galaxy AI
No (same on both)
What does this mean?
Galaxy AI is Samsung's name for its set of AI features, such as live translation of phone calls, writing help and photo editing that fills in parts of a picture.
Samsung lists which phones get Galaxy AI, at launch or through a One UI update. Some features work on the phone itself and others use the internet; Samsung lists which is which, and availability varies by language and country.
Matters most if: You want AI features such as call translation or photo editing built into the phone.

Battery1 gain · 1 unconfirmed
Battery capacity
3000 mAh›4500 mAh
What does this mean?
How much charge the battery holds, measured in mAh (milliamp-hours). Samsung lists a typical figure; we show the one Samsung gives.
A bigger number stores more energy, but how long a charge lasts also depends on the screen, the chip and which features you use.
Battery life (Samsung's figure)
Up to 17 hours of video playback›Not stated by Samsung
Samsung gives a different figure for another version: Galaxy S8, International version: Up to 16 hours of video playback.
What does this mean?
Samsung's own figure for how long a full charge lasts in one of its tests, usually hours of video playback (talk time on older phones).
It is a lab test of one activity, so real use with a mix of apps is usually shorter. Compare it only with another Samsung figure for the same test.
Matters most if: You are often away from a charger all day.
Camera6 gains · 2 changes
Rear cameras
1›3
What does this mean?
How many cameras are on the back. Each one is a separate lens for a different view: wide (the main camera), ultra wide and telephoto (zoom), depending on the model.
More cameras let you switch between a wide scene and a zoomed-in view using real lenses instead of cutting out part of the picture.
Main camera
12 MP›108 MP
Samsung gives a different figure for another version: Galaxy S8, Japan version: 12.2 MP.
What does this mean?
The resolution of the main camera's sensor in megapixels (MP), meaning millions of light-catching dots.
High-megapixel cameras usually combine neighboring dots into a smaller photo by default; you can switch to full resolution for large prints or cropping.
Matters most if: You want full-size photos for large prints or for cropping later.
Ultra wide camera
None›12 MP
What does this mean?
The resolution in megapixels (MP) of the ultra wide camera: the lens that fits the most into the frame.
Use it for group photos, rooms and landscapes when you can't step back.
Matters most if: You shoot group photos, small rooms or landscapes.
Telephoto camera
None›12 MP
What does this mean?
The resolution in megapixels (MP) of the telephoto camera: a separate zoom lens that sees far-away things as if you were closer. "None" means the phone has no telephoto camera. Some Ultra models have two.
At the telephoto's own zoom level, the photo comes from a real lens instead of a cropped, enlarged image.
Matters most if: You photograph kids' sports, concerts, pets or wildlife from a distance.
Optical zoom
None›5x optical zoom
What does this mean?
How far the telephoto lens zooms on its own compared with the main camera (1x), for example '3x optical zoom'. Where Samsung lists two telephoto lenses, the comparison uses the longer one.
At this level the lens does the zooming, so no part of the image is cut away. 'Optical quality zoom' figures some models list come from cropping a high-resolution camera, not from a lens.
Matters most if: You compare zoom between phones: compare this row, not the 'up to' figures.
Digital zoom (most)
Up to 8x›Up to 50x
What does this mean?
The farthest the camera can zoom, with software doing the work beyond what the lenses reach. Samsung calls it Space Zoom on many models.
Past the lens's own zoom, the camera enlarges part of the picture and relies on processing to keep it sharp, so the highest levels lose detail.
Matters most if: You zoom far and need the photo to show fine details.
Front camera
8 MP›10 MP
What does this mean?
The resolution in megapixels (MP) of the selfie camera on the front.
A higher number keeps more detail in selfies and video calls, but light and processing matter as much.
Video (best)
4K 30 fps›8K 24 fps
What does this mean?
The highest video quality the rear camera records. 4K and 8K describe the picture size (8K is larger), and fps (frames per second) is how many still images make up each second.
Higher settings make bigger files, so long 8K or 4K 60 fps clips fill storage quickly.
Matters most if: You film a lot.
Screen3 changes · 1 unconfirmed
Screen size
5.8 in›6.9 in
What does this mean?
The screen size, measured corner to corner (diagonally) in inches. 1 inch is 25.4 mm.
Samsung measures the screen as a full rectangle, so with rounded corners the visible area is a little smaller.
Screen type
Super AMOLED›Dynamic AMOLED 2X
What does this mean?
The type of screen, in Samsung's own words, such as Super AMOLED or Dynamic AMOLED 2X. AMOLED screens light each dot on its own, so black areas are truly black.
The name alone does not tell you how bright or sharp a screen is, so compare the brightness, resolution and refresh rate rows.
Refresh rate (most)
Not stated by Samsung›120 Hz
What does this mean?
How many times per second the screen redraws the picture, in hertz (Hz). 120 Hz means up to 120 times a second.
A higher rate makes scrolling and switching apps look smoother, and uses more battery.
Matters most if: You scroll social feeds, read long pages or play fast games.
Resolution
2960 x 1440 (Quad HD+)›3088 x 1440 (Quad HD+)
What does this mean?
How many dots (pixels) make up the screen, written as height x width, with a name such as Full HD+ or Quad HD+.
On screens of the same size, more pixels show text and photos in finer detail.
Adaptive refresh rate
Not stated by Samsung (for both)
What does this mean?
The range of refresh rates the screen moves between on its own, in Samsung's words, such as '1~120Hz'. A screen that can slow to 1 Hz saves battery on still images.
The screen speeds up for scrolling and games and slows down for reading, to balance smoothness and battery life.
Matters most if: You care about battery life as well as smooth scrolling.
Peak brightness
Not stated by Samsung (for both)
What does this mean?
The brightest the screen can get, in nits (a unit of screen brightness; higher is brighter), as Samsung measures it.
A high peak brightness makes the screen easier to see in direct sunlight. Makers measure peak brightness in different ways, so compare it only between phones from the same maker.
Matters most if: You use your phone outdoors a lot, such as for maps or photos in sunlight.
Design & buttons3 changes · 2 unconfirmed
Unlock
Fingerprint (on the back), Iris Scanner, Face Recognition›Ultrasonic Fingerprint (in the screen), Face Recognition
What does this mean?
Ways to unlock the phone with your body instead of typing a PIN: a fingerprint sensor (in the screen, the side key, the home key or on the back), face recognition, or on some older models an iris scanner.
An ultrasonic sensor in the screen reads your finger with sound waves; others use light. Where the sensor sits changes how you unlock the phone with one hand.
Weight
155 g›208 g
What does this mean?
How much the phone weighs in grams (g); about 28 g is 1 ounce.
You feel the weight most when you hold the phone up for a long time, such as reading or filming.
Size (mm)
148.9 x 68.1 x 8.0›164.8 x 77.2 x 8.1
What does this mean?
The phone's size in millimeters (mm): height x width x depth (thickness). 25.4 mm is 1 inch.
Height and width tell you whether it fits your pocket and hand; depth is how thick it is.
Materials
Corning Gorilla Glass 5 front and back›Not stated by Samsung
What does this mean?
What the outside of the phone is made of: the cover glass over the screen and back, and the frame around the edge, as Samsung lists them.
Glass names such as Corning Gorilla Glass Victus or Gorilla Armor are tougher generations of glass; a titanium or aluminum frame changes the weight and feel more than the strength in daily use.
Headphone jack
Yes›Not stated by Samsung
What does this mean?
Whether the phone has a 3.5 mm socket for wired headphones (the standard round headphone plug).
Without the jack, wired headphones need a USB-C plug or an adapter, or you use Bluetooth earbuds.
Water and dust resistance
IP68 (same on both)
What does this mean?
A standard code for how well the phone keeps out dust and water. The first digit is dust (6 means dust-tight) and the second is water (8 is the highest of the usual ratings).
Samsung tests in fresh water; salt water, pools and soapy water are not covered, and the protection can wear off over time.
Charging & connections1 gain · 3 changes · 3 unconfirmed
USB port
USB-C, USB 3.1 Gen 1›USB-C, USB 3.2
What does this mean?
The kind of USB port Samsung lists: Micro USB on older phones, USB-C on newer ones, with a USB version such as USB 2.0 or USB 3.2. It concerns moving data over a cable, such as copying files to a computer.
A higher USB version can copy files faster with a cable that supports it. Charging speed is listed separately.
Wired charging
Fast Charging›Up to 25W
What does this mean?
How fast the phone charges with a cable, in Samsung's words, such as Super Fast Charging (25W or 45W). W (watts) is how much power the charger can deliver.
The top speed needs a charger and cable that support it; recent Galaxy phones come with a cable but no charger.
Matters most if: You often need a quick top-up before heading out.
Wireless charging
Fast Wireless Charging›Up to 15W
What does this mean?
Whether and how fast the phone charges on a wireless charging pad, in Samsung's words, such as Fast Wireless Charging 2.0.
The fastest speed usually needs a matching Samsung charger. Wireless charging is slower than a cable but saves plugging in.
Wireless PowerShare
Not stated by Samsung›Yes
What does this mean?
Wireless PowerShare lets the phone wirelessly charge another device, such as Galaxy Buds or a Galaxy Watch, placed on its back.
It works with devices that charge wirelessly, and it uses the phone's own battery.
Matters most if: You carry wireless earbuds or a watch and want to top them up away from a charger.
Wi-Fi
Wi-Fi 5 (802.11ac)›Wi-Fi 6
What does this mean?
The Wi-Fi generation, such as Wi-Fi 5, Wi-Fi 6E or Wi-Fi 7. 6E and 7 can also use the 6 GHz band, which is less crowded. Older phones list only the 802.11 letters (n is Wi-Fi 4, ac is Wi-Fi 5, ax is Wi-Fi 6).
A newer generation helps only with a router that supports it, and the 6 GHz band is not allowed in every country.
Matters most if: You have, or plan to buy, a Wi-Fi 6E or Wi-Fi 7 router.
Ultra Wideband
Not stated by Samsung›Yes
What does this mean?
Ultra-Wideband (UWB) is a radio chip that measures how far away another UWB device is and in which direction. It only works with another device that also has UWB.
With a tracker tag that has UWB, such as a Galaxy SmartTag+, the phone can show distance and direction to find keys or a bag.
Matters most if: You use tracker tags to find keys or bags.
mmWave 5G
Not stated by Samsung›Yes
What does this mean?
mmWave ("millimeter wave") is a high-band type of 5G. The more common type, Sub-6, uses frequencies below 6 GHz. Usually only the US versions of Galaxy phones can use mmWave.
You need a carrier with mmWave 5G where you use the phone; the carrier's network decides which type the phone uses.
Matters most if: Your carrier offers mmWave 5G where you live or work.
Qi2 magnetic charging
Not stated by Samsung (for both)
What does this mean?
Qi2 is a wireless charging standard with magnets that hold the charger in the right spot.
Samsung says which Galaxy phones work with Qi2 chargers, and whether they need a case with magnets for the charger to snap on.
Matters most if: You want a charger or stand that snaps onto the phone.
Bluetooth
v5.0 (same on both)
What does this mean?
Bluetooth connects wireless accessories, such as earbuds and watches, to the phone. The number, such as v5.3, is the Bluetooth version.
Newer versions add features such as LE Audio, but your earbuds or watch need to support them too.
SIM
SIM card (eSIM not stated) (same on both)
Worded by this site from Samsung's eSIM and SIM card slot details; Samsung's own SIM wording for this version was not checked.
What does this mean?
Which SIM the phone takes: a SIM card from your carrier in a tray (nano SIM), an eSIM (a digital SIM built into the phone), or both. Samsung lists the combinations, such as "SIM 1 + eSIM".
Whether you can use eSIM depends on your carrier and country. Some versions of a model take two SIM cards, others one SIM card and an eSIM.
Matters most if: You travel abroad or want two phone lines on one phone.
FeliCa
Not stated by Samsung (for both)
What does this mean?
FeliCa is the contactless chip behind Osaifu-Keitai, the tap-to-pay service used in Japan for transit cards such as Suica and e-money such as WAON.
Samsung Japan lists it for the Galaxy versions sold in Japan; versions sold elsewhere do not have it.
Matters most if: You live in Japan, or want to use Suica or other Osaifu-Keitai services.
Chip & storage3 changes
Chip
Octa-core (2.3GHz Quad + 1.7GHz Quad), 64 bit, 10nm processor›7nm 64-bit Octa-Core Processor (3.0GHz max + 2.4GHz + 1.8GHz)
What does this mean?
The main processor: the part that runs apps, camera processing and on-device AI. Samsung uses its own Exynos chips in some countries and Qualcomm Snapdragon chips in others, sometimes for the same model.
Where the chip depends on the country, the page shows a switch for the versions Samsung lists. A newer phone can have an older chip, so compare the chip names rather than the year.
Matters most if: You are buying a model that was sold with two different chips.
RAM
4 GB›12 GB
What does this mean?
RAM is the phone's short-term working memory for the apps running right now, measured in GB (gigabytes).
More RAM lets more apps stay open in the background. RAM is separate from storage, which holds your apps, photos and files. On some Galaxy phones it depends on the storage size or the country.
Storage options
64 GB›128 GB, 512 GB
What does this mean?
How much space the phone has for apps, photos, videos and files, in GB (gigabytes) or TB (terabytes; 1 TB is 1,000 GB).
Each storage size is sold at its own price, and not every size is sold in every country. You get less usable space than the number shown, because some of it holds the phone's own software.
Security chip
Not stated by Samsung (for both)
What does this mean?
A separate secure processor that keeps passwords, PINs and other sensitive data apart from the rest of the phone. Samsung calls it Knox Vault.
Phones where Samsung names no security processor still have Samsung Knox security in their software; this row only shows a separate chip Samsung names.

What's new
RSS feedAdded Samsung Galaxy Note
Galaxy Note10 and Note20 phones (Note10, Note10+, Note10+ 5G, Note10 Lite, Note20, Note20 5G, Note20 Ultra and Note20 Ultra 5G), checked against Samsung's own pages only, with a page for each model and comparisons with any Galaxy S, iPhone or Pixel. Older Galaxy Note phones, from the first Galaxy Note (2011) to the Galaxy Note9, are on the timeline by year. Galaxy Note and Galaxy S Ultra pages now have an S Pen row.
Added Samsung Galaxy S, iPhone vs Galaxy and Pixel vs Galaxy
Galaxy S phones from the first Galaxy S (2010) to the Galaxy S26 series, checked against Samsung's own pages only, with a page for each model and a switch for models Samsung sold in separate versions, such as with an Exynos or a Snapdragon chip. iPhone vs Galaxy and Pixel vs Galaxy pages compare only what both makers publish, in each maker's own words, and you can pick a Galaxy on the iPhone and Pixel tabs.
Added prices by storage and configuration
Spec pages now list the launch price of each storage option, Mac configuration or Apple Watch case, and today's price on the maker's own store for models still sold, from Apple's and Google's own pages only. Comparisons call the old price row the starting price and add the price of the same configuration on both models: the same storage on iPhone, iPad and Pixel, the same memory and storage on Mac, and the same case on Apple Watch. iPhone pages also show Apple's wired fast-charging figure.
