iPhone 13 Massive Battery loss. Failure to charge

[DallasCowboysFan]

I have an iPhone 13 and an iPhone 17 on order. I can't wait to receive it. Especially now. For the past few days my phone has not been able to charge past 43% even if I keep it plugged in all night. It's not the battery, it is holding 96% of its total capacity.

I have not added any apps or changed any notifications.

The one thing that has changed is that I recently upgraded the software that was available.

The phone seems to drain faster than usual as well.

I am confident that the new software upgrade is the problem

I have not dropped my phone or done anything to injure it.

I have tried charging it from different sources and nothing improves the situation.

I have turned it off and on a few times to reboot it

Does anyone else have this problem or am I alone?

Thanks

How do you know if this is accurate? It isn’t always correct. What does Coconut Battery say the capacity is? How many charge cycles?

It sounds like it could be a battery issue to me. My mom once had a three-year-old iPhone where the reported battery capacity was in the 90% range, but it was doing all kinds of funky things. Sometimes it’d show it charged to 100% in a matter of minutes or seconds. Sometimes it’d last a long time when it said it had 1% charge left. Most of the time, the phone would just randomly shut down when it was nowhere near 0% reported charge.

I know none of these are the same symptoms as yours, but lithium batteries do weird things once they’re past their lifespan.

EDIT: I see in another post that you had the battery replaced. Was it done officially through Apple or an Apple Authorized Service Provider? Or is it a third party battery?

Battery or power management related chips are the issue. This is not software.

Take it to a third party store for logic board diagnosis or bring it to Apple to an expensive whole unit replacement.
