I have had my Google Pixel 6 phone for about 3 years and the battery has now warped the phone. I decided that after looking on-line, at how this was done, it looked like an easy task to swap out the old battery and put in a new one. I bought the first one from Amazon it was a higher capacity (6200 mAh) than the previous one (4614 mAh). After following the Youtube video it wouldn’t turn on. The only thing that happened was that the phone got warmer. I tried pressing and holding the power button for 30 seconds but still nothing happened. I left it charging for about 90 minutes, but, still nothing happened.
I took the phone apart and refitted the new battery, but, nothing happened. I then put back in the original warped battery and that now doesn't work either, even leaving the old one charging in the phone for 90 minutes. Since then I bought another battery, from Amazon, with the same capacity as the original one (4614 mAh) and the same problem persists in that it will not power on after charging it for 90 minutes, even holding the power button for 30 seconds.
Am I missing something or could there be issue with the batteries that has affected the phone, like maybe google doesn’t like the end users doing their own repairs. I’m looking for any advice before I take it to a phone repair shop.
