okay....well,since im writing this out of frustration,my issue is that with my lumia 925,its been nearly one year since i purchased it and i live in egypt.Its a great phone and very sexy looking plus i like windows 8 plus the 8.1 update,but...........the battery is such a turn off for me and im having nightmares and stress from it since i only do messaging with this mobile and some browsing it only last for me 2-3 hours a day and with a discharge rate from 8% to 24% and i have everything off and checked the forums here for battery saving but no avail, i even did a hard reset about 4 times but it no results whatsover ,im a heavy whatsapp user since i connect with my friends,family,girlfriend and co workers through it and its unbelievable that it drains so much and overeats from that while my mothers blackberry z3 is cruising thru whatsapp for about a day and a half without a charge.My phone is a battery hog,i even have the charger with me all the times and a spare traveller battery charger but it sucks the juice out of it. Im seriously of getting a new phone like blackberry q10 or lg g flex or htc one maxx since their battery is much more efficient . Can anybody tell me whats the issue with my mobile??
