Just got my mercury march 3rd. but i've been having major battery issues with it since the day i got it. if i play a game, or use an app, for about 5 minutes or so, the battery gets extremely extremely hot, and i usually lose 15 to 20% of battery. also if i have my phone on standby or in my pocket or something, the battery gets extremely hot and wastes a lot of power. last night i stopped charging it at around 2 and it had 97%. when i woke up at 8, it was at 43%. should i just get a new battery, or is this a phone issue?
