Launch day 12 Pro at 99% on iOS 15.2.
I don't really understand why my battery is dropping like that... It was really perfect until I update it to iOS 15...
I'm not sure if iOS 15 is really causing that since I charge it as before and carefully not in hot area, but these is definitely an issue since iOS 15... Look at my coconut battery history.
It have to be a iPhone 12 series thing, since I’m on 14.1, and my battery is at 86%. From the rumors I read in 2020, Apple must have used cheap batteries in the 12 series. I haven’t heard much nor have looked to see if the 13 series was having the same issue.
Cheap batteries in such an expensive smartphone? I won’t be impressed if that is the case. My battery health is freakishly low after just a year and I’m tempted to try for an answer off Apple as my previous iPhone was 2 years old with a similar battery capacity. Not impressed.
It is only my theory, but I believe battery degradation is highly influenced or progressed by the amount of time a phone/battery has spent charging. At least, that is the common denominator I am seeing.Thanks
Thanks for the response. What would
you recommend on charging frequency? It does charge quite fast even though I’m charging at 5W. Applying the 40-80% charge process The phone would be connected about 2 times a day to stay in that range.
I’m currently calibrating the battery and will do a last attempt on preserving battery health. Thanks!
If it’s true I believe it. There should be no reason to have a battery at 86% for a device that’s 14 months old. All I can do at this point, is wait for the battery to hit 80% and have Apple replace the battery through AppleCare+. I’ll be keeping this phone as a backup when I upgrade to the 14 Pro Max.
If my battery falls to 80% in under 24 months, I will be getting Apple to replace it for free. There is clearly a quality issue for a battery to deplete in such a short space of time.
How is that moot? It’s the way Optimized Charging is supposed to work. It’d only be moot if it charges over 80% too early. Batteries are gonna loose charge over time even when you don’t use it at all and you don’t need to charge the 1-2% it loses at the full 20W to top it off.As I have said before, when Apple does the 'Optimized Battery Charging', the phone is kept at that 80%. If your phone battery's charge level goes below 80%, Apple keeps trickle charging it, which makes the whole 80% charge level moot, imo.
What I mean is, Apple continues to trickle charge the phone. The charging is not cut off at 80%, but maintained. So, the phone continues to charge overnight.How is that moot?

Trickle charging doesn’t damage a battery in anyway and partial charging is better for a Li ion battery and their might be other reasons too for them to hold on to this practice. They definitely know their batteries better and that’s what they think is best.What I mean is, Apple continues to trickle charge the phone. The charging is not cut off at 80%, but maintained.

Sorry, I have to disagree. Following Apple’s steps have not helped reduce battery wear on most devices, as showcased by this thread.Trickle charging doesn’t damage a battery in anyway and partial charging is better for a Li ion battery and their might be other reasons too for them to hold on to this practice.
