I presumed the battery had died, but no matter how long I charged it, from any cable, it wouldn't turn back on. Eventually, the inevitable happened and my phone shut down. I had already been running Android 12 for a couple months by that time so I'm not sure that was the direct cause, though I was on vacation in a warm climate at the time.
Some of my research indicates a hard reset might work (I doubt it though) and it's possible that my battery died the same time I upgraded Android, but I'm not sure about that either.īack in December my Pixel 4 XL got that question mark in the battery, and a notification that the battery indicator had failed. I tried entering fastboot and when it came back into normal mode it actually displayed properly for a bit but quickly errored out again.ĭoes anyone have any ideas how I could potentially diagnose this?
I have booted into safe mode and observed that it was having the same behavior. I tried an application called easy battery calibration, but it states that the battery is constantly 50% charged regardless of how long it's been plugged in. A consequence of this is that I've had my phone completely run out of charge and generally seems to be unstable. My phone seems to not know how much charge it has anymore and the percentage amount now displays a ?.
