Found the culprit that suck my 550 battery juice.

[marcoslai]

My 550 was acceptable in battery performance since I bought it last week,but it started to drain like hell 3 days ago,battery drop to 30% from full in 8 hours without any usage,and the phone turn so hot,seems never cool down. I browsed the web and tried all kind of solution with no luck,until today,I did this:
Uncheck all boxes under 'Back up to Onedrive' under Setting > Update & Security > Back up.

OS build: 10.0.10586.164.

This is weird. My another Android phone never like this with all back up feature turn on.

Just a sharing,I hope this help those with same issue.

Interesting, my 550's battery life was fine for a few months then it fell through the floor - now I don't get through a full day without a recharge. I found some articles that helped me switch a bunch of things off, but even having done that a few weeks ago the battery life is still woeful. Any ideas?
