wont turn on after replacing failed battery
pixel phone died.
removed battery and it was at 2.8v (dead) — replaced. now at 3.8v+
broke screen during battery replacement. replaced with new screen.
Now with new, fully charged battery and new screen, it still won’t turn on.
- tried holding power for 30+ secs and checking “find phone”
- tried holding volume down + power
- connect to charger via power meter and I see that it charges at 5V@1A but screen is blank.
The initial failure was when I was in the desert, moderately hot and running a GPS mapping app that was keeping the phone awake and active. I think that the battery drained below 3.0v and was ruined. But now I don’t understand why after replacing the battery and screen the phone is still not turning on.
When the battery completely dies, is the motherboard at risk of being damaged?
I have test equipment. Is there any material on debugging the motherboard? I see there are lots of test pads but I do not know what they are for. I see that when I connect the new battery, a test pad near the battery connector reads the battery voltage (relative to one of the ground connections to the midplane. I also removed the power, volume buttons and observed that the power button works (continuity between two pins with depressed).
Thanks for any information you might be able to shed on this issue.
