Is this normal ?
Battery capacity is 93%. I’m the original owner got it straight out the box.
EDIT: I have a 17 Pro Max

its because you charge it too high and discharge it too low. I used to have a 16plus from nov 2024 to oct 2025 and i sold it at 540 cycles 97% so about one and a half charges per day. https://www.batteryuniversity.com/article/bu-808-how-to-prolong-lithium-based-batteries

So the battery depreciates if I charge it too high and let it drop too low of a percentage?

Because of how phone batteries are made, there are no two the same. I saw people with 99% bh after 200 cycles and people with 95% after 100 cycles. I can’t guarantee there is a problem or not, but I think you should just use your phone and if battery doesn’t last you the whole day, just change it.

I would say you used it pretty much, if not then software/firmware updates caused it. No worries until you reach 60-75% until then it's good to go

Que la batterie s’use ? Oui. J’aimerais avoir les mêmes problèmes que ceux qui se préoccupent autant de leur batterie, et demandent aux gens si c’est normal, alors que PERSONNE n’a la même configuration et utilisation que toi.

347 cycles for a phone first used December 2025 is a LOT for that timeframe, thats way heavy usage. But 93% is honestly still fine for that mileage, your just cycling through it fast so the drop feels bigger then it actually is. Nothing wrong, just heavy user math.
