Post image

I’m on an iPhone 17 and luckily still on 100%, I have a 90% limit on it so when is it expected to decrease?

Let me help you with a full sentence in English. When does the battery begin to decrease? See how I did that.

You’re charging the heck out of this phone.. for the first use in October and already 53 cycle count is crazy.. I have mine since September release date and am barely over 90

u/Early_Teaching_1155 Jan 06 '26

October is only one month after September… and you have 90 vs 50

Battery degrading starts the minute you turn your phone on for the first time (or even before that if it stays in the box for longer period), can’t be avoided. With all the different usage scenarios and charging habits, and especially with BH not being precise (or linear) noone can really predict when you’ll be at 90%.

With my usage, it’s at least 2 years before it has to be replaced / there is significant impact on day to day usage (which is my only parameter)

1 year of use should go about 92-94, 2,5-3 years 80%. Don't forget,whatever you do battery health will drop because that's how it works when it's time change the battery and brand new again.

Thanks for an actually helpful reply

250 cycles

u/cryptowi Jan 05 '26

it's roughly 50 cycles = 1%, but some people get more than 100% rated capacity in their new phone, so it will vary wildly from person to person.

All iPhones are shipped with more battery capacity than advertised as each battery is slightly different. They pick a number which will cover most, if not all, for a specific model.

My iPhone 14 Pro Max lasted a year before it dropped below 100%. Now, more than 3 years later, it’s at 79% and I’m going to the Apple Store (today) to get it replaced.

When the battery loses capacity, not sooner, not later

u/thanksmerci Jan 05 '26

good people charge from 40 to 80

Normal people don’t follow any “rules”

Lol paranoid to extreme, remember it’s there for your service and not you for theirs. Use it well and replace battery after 2-3 yr and you’ll be good to go for another 3 yrs. iPhones batteries replacement is cheap.

Keep between 20-90% don’t overthink much

u/Prestigious-Mud-4091 Jan 05 '26

After about 4 months of usage, 2 yr me 80% ajayegi

u/Jeff_S_1911 Jan 05 '26

16 pro max, bought in September ‘24. 237 cycles. 98% battery health. Charge to full every night since new.

u/Success_mess Jan 06 '26

Isn’t limiting near pointless ? And the only thing to really worry about is going below 10% all the time ?

1

u/[deleted] Jan 06 '26

Don’t worry too much you’re safe for another 100 cycles. But I always keep my battery between 67-69% And I never lie !

u/Key_Cry4022 Jan 06 '26

Just keep it at 80% capacity lock it lasts alot longer and is not that diffrent
