New battery: lightning icon blinks, won't turn on
I bought a second hand Moto Z Play (XT1635-01), and the battery swelled up after a bit of usage so I bought a new one plus some Tesa tape from iFixit; it took some time to replace and the first charge went smoothly so I left it unplugged to see how long it’d last.
At 63%, it turned off by itself like it did with the old battery. I turned it back on, and it booted alright at the same % but shut down shortly. When I plugged the charger, it went through a few cycles of (lightning bolt in a circle -> charging LED blinks -> black screen) before showing a % indication, but it wouldn’t boot: the light blue Moto screen shows for a second and it starts allover again.
Current status: No % indicator, just the lightning icon loop. The only “stable” screen I can reach is the bootloader mode, which alternatively shows “Battery Low (Charging)” and “Battery OK”. Trying to boot system or recovery gets me 1 second of blue screen so I can’t even wipe/reset it.
Did I get a bad battery?
Is this a good question?
