Battery
Video playback
Lose (-3 hours)
39 hours›36 hours
What does this mean?
Apple's battery test: how many hours the phone can play video nonstop on a full charge, in Apple's own lab conditions.
Real life uses more power (games, camera, weak signal), so you will get fewer hours than this. The number is still useful for comparing two phones, because Apple tests them all the same way. Batteries also wear out: an older phone today holds less than it did when new. You can see how much your current battery has left in Settings > Battery > Battery Health.
Matters most if:
You often run out of battery before the end of the day.
Screen
Screen size
Different (-0.6 in)
6.9 in›6.3 in
What does this mean?
Screen size measured corner to corner, in inches. One inch is 2.54 cm.
A bigger screen is easier to read and better for video, but the phone is larger and heavier. A smaller phone is easier to use with one hand and fits more pockets.
Design & buttons
Weight
Different (-22 g)
233 g›211 g
What does this mean?
Weight in grams. 100 grams is about 3.5 ounces.
Around 30 grams difference is noticeable when holding the phone for a long time, lying down, or in a shirt pocket. Bigger batteries and screens add weight.
Chip & storage
Chip
Different
A19 Pro›A20 Pro
What does this mean?
The chip is the phone's brain. It runs every app, processes photos and handles the AI features.
A newer chip makes the phone faster, keeps it fast for more years, and decides which new features it can get. Apple Intelligence, for example, only works on recent models.
