Not booting, only vibrates one time. Battery replaced, no improvement.

My Pixel XL stopped booting a bit back, and given the battery decay (<50% life per accubattery) before it failed and it’s behaviour afterwards, the failure to boot being battery related seemed likely. Sadly, that doesn’t seem to have been the primary issue.

Swapping the battery didn’t change how the phone behaved since it started failing to boot. All the phone has done is vibrate once when holding the power button for long enough, or when held in combination with the volume button.

Still seems unlikely it’s the screen though as the fingerprint sensor doesn’t ever vibrate for failed reads like the phone has actually booted, and a computer never sees the phone.

It does seem like the new battery is at least charging as the upper part of the phone is getting warm whereas the previous battery had almost entirely stopped causing any heat when plugged in. So something’s happening, but I guess something more than the battery was broke, and I’m not sure how to narrow that down.
