Erratic battery behavior

[Nick Schneider]

My battery life after about 70% is wildly erratic. It will go from 70 to 15% in less than 15 minutes. If I shutdown, wait, and restart, it will be at 65+%. See the pic, those bumps are reboots, not recharges.

Any ideas?

Had the same problem with a nexus 5. Turned out the battery was swelling and dying. Might be the end if the road

Both battery connectors need to be fixed: black connector is on mainboard and the white connector's battery cables. Fixed both and you will have problem free.
