I am having battery issues as well. I have all email push to manual and all other battery drainers turned off. phone lasts half a day at best. Could this be something in an update that has been recently installed? my phone has os version 7.10.8112.7.
Lumia 900 that I was loaned set up exactly the same as 800 lasted only half the time, although didn't have it long enough to see whether battery improved after a number of charge/discharge cycles which is sometimes the case.
These are the background tasks that are actually running
I have other background tasks listed in Settings-->Applications-->Background Tasks, but they are not pinned on my start screen and have push disabled from within the applications. Will this result in any battery drain?
These are the active tiles on my homescreen
Email (2 emails, both push)
From what I see, Notifications in 'me' are pushed. People/pictures updated their feeds on demand, when needed.
My battery lasts around 14 hours.
I used Nokia for many years in Europe and loved it.
When Lumia 900 came out I thought "I'm going home".
But I have the same issue for a while since I bought Lumia 900 beginning of May. Especially disturbing the phone getting really hot from time to time, it happened few times since I got it. And the power drain is horrible - but also not always. Can't figure out those coming-going issues. Anybody knows where to read about it?
have the new lumia 925 and even after a couple of mins using it it gets unbareable to touch and it didn't help the mid frame is aluminium um worried its going to fry out or blow up even when i use the wireless charging plate and shell you could cook an egg on my phone
