When I got my new samsung s4 I barely was able to get a day out of it. I've had my phone for only ~ 2 months and now I'm experiencing battery problems. Phone turns itself off randomly like it has a flat battery at percents anywhere above 50. I must plug in the charger in order to successfully turn it on again. The battery percent reading is completely wrong. Anyone else's samsung galaxy s4 battery playing up?
Battery level sometimes increases by itself without a charger plugged in: http://i.imgur.com/DQxncXX.jpg
Battery reading of about 50 something %, turns off, and once turned on again it'll read a very low digit: http://i.imgur.com/jXdlJwM.png
