Iphone 11 pro battery percentages jumping around (iOS 15.2 - 15.2.1)

[iwnlden]

Hello guys!

This is my first thread, I'm just gonna share my problem with my iPhone 11 pro, mainly about its battery percentages jumping around, it been doing like that so much, I've been trying to contact apple support but they ask me to reinstall the whole iOS, and I already did it and it still doesn't work, today they told me to bring it to apple authorized service centre to diagnosed, to see if my battery needs to be replaced. i was wondering do i need to replace the battery just because my percentages jumping around? my battery health situation is at 93% i think its quite normal for 2yrs of use and it can still go for a bit longer no?
anyway they did the mobile inspector thing on my phone and they found nothing wrong, and they couldn't explain what is going on about my battery.

did any of you guys experience the same issues? and how did you guys resolve this? thankyou in advance

Probably the battery has some issues so it has voltage fluctuations.

Too bad the warranty only covers when the battery drops lower than 80%

but does it mean i got a faulty device? cause its not my problem right? I'm not using the device while charging, and also I didn't use this device as a gaming too hmm
and here's my battery health, my weekly and daily usage

I see that you were using Facetime, it usually requires a bit of power.

I would say a weak lirhium battery will drop voltage and then climb a bit up when not draining.
I think it is too bad that Apple usually just checks the percentage and the number of cycles, when there's much more that can go wrong
