Hi everyone, I'm experiencing some weird problems on my Lumia 920. It's about the battery indicator. I use no battery apps, everytime I want to check my battery, I go to settings and down to the battery saver section, it tells me how much I have left. The problem is this morning, I went to sleep at 6 in the morning, wake up at 13:30 in the afternoon and my battery went from 90% to 83%, I guess that's normal, I lost 1% every hour ? And then I turn off my phone and restart it again just out of curiosity. When I checked after restarting my phone, the battery indicator in Settings dropped to 79%. So I restart my phone again, and my battery power continued to drop from 79% to 77% and 75%. It's really weird for me, because there's absolutely no apps running in the background, I'm at home so I only use Wi-fi, my 3G is switched to 2G and cellular data is turned off. I have this Lumia for 2 months now and the battery is always acting weird for me,even though I installed every released updates. Please suggest if I should get it fixed by a change of battery or is there a way to fix this without bringing it to Nokia Care ? I lived in Vietnam and Nokia Care Vietnam does not have a policy to return a defect unit, they just find out what's wrong and try to fix it, in like 2 months or something, so I truly hate to go to Nokia Care,(the experience is really bad), even to change a defect battery. Thank you very much for your time and attention.
