Battery stuck at 50%

[TheColin21]

Hey guys,
today my phone just didn't show any other battery capacity than 50%. I had it on my car dash charger for multiple hours. This evening it still turned off and showed the "Battery too low" screen, so I assume it did not charge.
First, TWRP also showed 50% and a very long weird number as CPU (top left), then it stopped showing anything about the battery

After I turned it off and tried to charge it, it crashed in the bootlogo and rebooted.

Any ideas what to do? I already reflashed the firmware.

Best regards
Colin

I have this problem too

Just use it till it gets fully drained then charge it?fully

Currently encountering the same issue with my OP5 now and when I consulted a tech regarding this one, he informed me that it may be a possible motherboard or battery issue. Will have my OP repaired by early January and hoping that it's only a battery issue(fingers crossed).

Looks like you drained the battery too much and the battery chip got confused. Or worse, one of the cells died. This doesn't just happen to OP5, but to all batteries.
There are a few options:

• Replace the battery: https://www.ifixit.com/Guide/OnePlus+5+Battery++Replacement/103028
• Turn off the phone, then charge it fully while off. Then slowly drain the battery again, in a way where the phone isn't sleeping so Android can gather battery statistics.
• If above didn't work, then do above method, but also clear battery statistics in TWRP, or the recovery of your choice.
• There's the option of putting it in a vacuum sealed bag, and putting it in the freezer. Google for details, and do's & dont's.

Hope this helps!
