So as the title says my phone is turning off randomly at like 50% or higher. than it decides not to charge. After i take the battery out for a minute and put it back in, it charges but the battery goes back to the original percentage before it shuts off. I am running android 4.0.4 and did all the updates i could. I tried factory resetting, but that didnt work. Oh and now 4g and wifi decide to turn on whenever the hell it wants to. Here is a picture for the battery
