I got the new battery installed and drained it all the way down Does go to 100% but I have to restart it to get the percent to change and when it does it says around 71% or 80% until it dies.
Where did you purchase the battery from? If it wasn't an OEM part or made by a reputible manufacturer, it may be lacking some of the necessary sensors for determining percentages properly.
However, there is a quick fix that may work that you can try:
Charge your battery for a long period (overnight) so that it fully charges and then some. Ideally, do this when the phone is turned off.
Turn the phone on and use your device until the battery is completely drained and shuts off on its own (I would reccommend turning the screen off time to never and running a very long video with sound to speed this process up)
Plug your phone back into the charger and charge your battery to 100%. It is very important not to interuppt the charging process, so I'd probably leave the phone unattende overnight.
If this does not calibrate the battery properly, unfrotunately, the best option is probably to purchase a new battery. You can get an OEM battery from Google on the iFixit shop website: Google Pixel 8 Pro Battery - Genuine
Ok, great. If you purchased this from iFixit, I would suggest that you contact their customer service. If the battery does not work, they should probably give you a replacement/refund
that was this morrning, had it off the charger from 8am to 2pm it is telling me it is at 98% right now. It is acting like it does not want to update the percent.
