I fixed the battery drain on my Lumia 920

[Justin429]

It took several days to get the battery drain solved on my phone. After taking the update, I did a factory reset and reinstalled everything manually instead of restoring the backup. Most background processes had been disabled through battery saver with exception to those that seemed important or useful. Unfortunately I was still losing charge at an alarming rate. Finally, I disabled the background process for OneDrive yesterday afternoon. Now my battery is a beast! I can't say it will solve your problem, but it solved mine.

Report back in two weeks and we may believe it's fixed. I've been there and a few days later it's back to normal drain...

My Lumia 920 cannot hold the 100% after a night when it's turned off... The Moto G can though...

And how can OneDrive be the solution? I checked the usage of OneDrive on my phone, and there was zero usage!

As I said, it might not solve your problem, but it did solve mine.

I call it a lie

No way are you getting 100% on a restart. That vibration and screen lightening up alone must use at least 1% if not 23%.

I also Turner off Glace screen and my battery was a beast for 2 days. Now it's back to normal drain.

I do not have any idea how to fix this. So annoying.

Overall I like WP 8.1 a lot.

Exactly, I may lose like 20%... Pretty weird for a phone that is "turned off"

It's been a week now and my battery life is still on par with pre-8.1 longevity since disabling background tasks for OneDrive.

It's been a week now and my battery life is still on par with pre-8.1 longevity since disabling background tasks for OneDrive for business applications.

That's all well and good, unless you rely on syncing with OneDrive-

I'm still on 8.0... with all the issues being reported with battery, usability, loss of features, I'm still weighing the risk-reward ratio before 'uprgrading' to 8.1... Don't know if Cortana is worth it-- yet.

What does the background task of OneDrive do?
I would think photo upload and stuff is separate... and it doesn't have a live tile...

Beats me. All I know is that disabling that background task solved my battery issue.

There really needs to be some explanation on what disabling background tasks do for each app. 8.0 had it.

The explanations were almost always bull****
