Well my friends this is a major problem for our L925's and totally true...I have the phone for about a month and the battery lasts around 11 hours a day with ''moderate ''usage which is based on the following: glance screen off,location off, all background apps except viber and weather off, touch sensitivity normal, theme is dark, wifi/celllular on all day!
Usage: 1:20 hours of talktime (tops), 20 -30 messages per hour through fb Chat (have to keep in touch with my girlfriend ) on the integrated Messenger and about an hour of Web browsing! Actually this is light usage in my opinion but i call it moderate now because I want to be as kind as possible to my beloved Lumia...
It's not the apps, it's poor battery management from the OS...My previous phone, an htc one s, could get 3 hours of usage more than my L925 with the same settings and with a dual core 1.7 ghz cpu and a battery of 1600 mah! It was also a lot faster! A LOT! I think that the only thing that our phone lacks is battery power and that's not only my opinion but almost anyone's who have used another flagship phone except Windows phones (like iPhones and android devices).
I don't understand how some people can get a day (which is 24 hours not from morning to bed,just wanted to clarify that) out of that battery... You must either don't use your phone
I have also run the wp bench app and on the battery test my phone lasted 3 hours and 11 minutes before turning off...And guess what, that was one of the Top scores for the lumia 925! Most people dont even get to 3 hours!
Last night i went to watch a football game (90 minutes) and in the begining of the match I had 49%...Guess what happened after 20 minutes of usage (showing off the phone to my friends to be precise)...Yeap! You guessed it! BATERRY DIED LIKE IT WAS ON 10 %!
This is not a flagship and shouldn't be sold at this High price, I won't pay again so much Money just to have something beautiful!
And YES I do close the apps i use after i stop using them...
I have spoken with a Nokia guy and he told me that this battery life is normal...
Well this is not normal and it's one of the reasons I'm selling this phone to get something else if the wp8.1 update doesn't fix the battery life!
I love my 925 but it just dies on me when I need it...Which sucks!
