Using Lumia 640.
The battery was ok with W8.1. With W10 10586.63, the battery is draining faster. Well, that's natural, I guess, as W10 uses more resources than 8.1. But even though some apps are "not allowed" to run in background, they still show notifications when battery saver is off. Need help!
Additionally, Outlook mail app is "always allowed" to run in background but it doesn't when battery saver is on. It needs to be synced manually to get mails at the time. Again, need help!

Can anyone who uses 950 for some time could write sth about SOT? I use Lumia 640 a lot (wp8.1) writing emails, web browsing and all those things that requires screen to be on and now wondering how it impact battery life in Lumia 950? Many people here write about 2-3 days battery life, where on my Lumia 640 I can't even get full 2 days

Hi,

I own a L640 LTE dual sim. with windows 8.1 on it, I usually got a full day of productivity without needing a recharge, with Windows 10 it has been all over from 5 hours of battery life to now being the same full day with the latest fastring update.

with moderate usage you can get a full day for sure, but not 2 days. try to set display brightness to medium and then turn on auto brightness.
