iPhone SE - goes dead with >30% battery

[BeatCrazy]

My daughter’s SE has been behaving very strangely. Even with >30% battery, it will often crash and display the “plug in to charge battery” icon. I plug it in, and it will show plenty of battery. If I unplug, it will sometimes crash again with the same plug in indicator.

I have done a full erase/reset, and it seems to help for a while, but never cures. I also notice that the battery will often drain very quickly, i.e. from 100% to 0% in less than a day with really no usage.

I assume it’s pretty much toast, as it’s 2.5 years old. Battery health shows 95%. Running 13.2.3

Sounds like the battery is probably still off somewhere despite the health that it might be showing.

battery. Have it checked.

Does the Apple store check battery health on out of warranty iPhones?

Of course.

Do you recall if this started after upgrading to IOS 13? That’s what happened with my 6s plus

Yeah, actually I think this only started with iOS13.

My old 6s shows 95% battery health too but in reality it's at about 50% capacity (per coconut battery and iMazing). The built in monitor is useless.

Battery is way past the period due for replacement.

Normally, you should replace every 12-18 months. You're on month 30.

It's just not true that iPhone batteries need replacement every 12-18 months.

It's just not true that iPhone batteries need replacement every 12-18 months.

That number is based on one cycle per day, or 360-540 cycles every 12-18 months. Apple batteries are designed for 500 cycles. And that assumes the battery itself doesn't age, which it does.

So 12-18 months is correct.
