Hi my pixel 3 is relatively new and was in excellent condition The battery got very low and it auto shutdown The problem is now when I plug in a charger it charges for 20 seconds then without me touching it tries to turn itself on the second it does it auto shuts down and then the cycle starts again 20 second charge - boot up - shutdown Again and again I left it for a few hours continuly doing this and it just kept going Any advice would be fantastic Cheers James
I would try booting into Fastboot (Power + Volume Down; Hold the Volume Down until it boots into Fastboot) and flashing a factory image. This will erase your data. If not, if you haven’t damaged your phone in any way a Pixel 3 has to still be covered under warranty… I’d get in touch with Google.
If you have already tried a qualcomm 12v charger (the multi-voltage chargers can sometimes get it past the boot loop) and it hasn’t worked, you are probably going to have to send your phone to google for a repair. Their idiocy with that auto-boot to a low-power state routine is terrible and there is no hope.
