iPhone 13 battery percentage stuck, only updating value on reboots

Im having the exact same issue with the Iphone 13 Pro 256GB i own, had it for 5 days and its doing the exact same thing, it charged overnight got stuck at 98% then rebooted to get it to 100% took it off and 12 hours later my phone was stuck at 100%, restarted again and it went down to 66% ( the actual correct figure it would seem )

After this ive noticed its not showing any battery drain now but it will show charge, i have tried soft reset, DFU, restore nothing works at all, its either an ios issue running latest version 15.0.2 or its hardware itself on the 13 models.

had an old iphone se with similar issue and got this exchanged it appears the same thing has creeped its head back around the corner without apple realising.

I have the same issue on the 13 pro, battery stays stuck and only updates on reboot. I have the phone for 1 day. Do you know if this is going to be fixed in the next update or how some solution for now. I havent used an Iphone since ihpone 7, so i have no idea what should i do

I’m currently experiencing the same issue again after installing the newest update. I had to factory reset my phone which seems to be the only fix. Might it be a software issue in which case apple will rollout a new update to fix the issue?

So I’ve managed to fix mine manually here’s what I’ve done :

firstly use the phone and it will start to drop eventually when you get to 35% battery plug it into iTunes and wait till it shows in the menu.

then follow the instructions to restore iOS ( does not wipe data )

this is usually performed by pressing volume up then volume down and then the power button till it goes into a reboot mode can’t remember the exact steps but they are online.

after a while a message pops up on the computer or mac saying restore iOS follow these instructions and let the device do its thing. Once this is completed connect using an approved apple 20watt charger and the original cable for around 3 hours till it shows either 98% or 100.

the device is now repaired and will drop as normal.

be advised however the first 15% does give the impression of a stuck battery however it is not. It is draining all be it very slowly !

not sure how this manages to fix the device but mines been perfect since and had no battery issues at all and easily lasts me longer than 38 hours on a full charge with heavy usage.

it looks like an iOS bug but fixed with an iOS restore.

hope this helps everyone

15.0.2 started this issue for me with iPhone 13 Pro Max. Battery % will show a full charge for 9-10 hours on idle, only updating when I manually turn off phone, turn it back on. (no hard reboot). Then it may show the updated % of 92-93%, stuck again until you reboot the phone.

ALSO, under Coconut Battery, my "health" after 15.0.2 looks like it took a major hit. Launch day...just 22 days ago, an awesome 103-104%. After 15.0.2 update, 94-95% (iPhone reads "Health - 100%)

Right now, I'm not sure what to believe, if the phone's numbers -%'s are totally messed up and Coconut can't read it...which I actually hope this is the case. OR, this update really did fry my battery. Only hope the next update will fix this!

Right now, I'm fairly disgusted with the way this brand new phone is acting.

Hi folks.

I purchased a new iPhone 13 Pro Max and i´m experiencing the same issue.

Unfortunately it has the same issue even when I updated to iOS 15.1 after get it out of the box.

I don´t really know how to fix this if I have installed the latest iOS version...

I’m having the same problem with my iPhone 13 Pro Max and I’ve only had it for 4 days. When I charge it, it only charges to 95% and then stops charging. I’m running iOS 15.1. I took it to the Genius Bar and they reset all settings but that didn’t fix it. I’m very frustrated.

I had the same problem in my new iPhone 13 Pro Max, after doing all sorts of software updates, batery calibration, etc etc nothing work, the same problem all the time… finally the apple store who sold me the phone took it for service, now I have to wait around 2 weeks to get the phone repaired….very bad Apple, the phone is not cheap.

i got the problem solved by the apple store I bought it, they replaced the rear part of the phone completely and just used the old screen and cameras. Now the phone is working perfectly.

everything was free of cost . Thanks a lot

I facing this issue as well in my iphone 13 pro max. Battery drops from 1-5% on every single reboot

Hope up coming iOS 15.1 will be fixed the issue!
