I have had my HTC Evo 4g since November of 2011. Maybe a month and a half after i got it the battery stopped fully charging and eventually it completely died. So i started using the extended battery. Well i dropped it and demolished the screen so i got a new one through insurance. i may only have had it for a month then the battery wouldnt hold a charge and it eventually died as well. So i put the extended battery in it and it completley died within 2 weeks !! last week i took my phone to a sprint repair shop and was told that both of the batteries sure enough was totally deceased so he ordered me a new battery .....YESTERDAY I GOT IT AND TODAY ITS COMPLETELY DEAD !!!!!! I dont understand why this is happening with my phone ! have anyone else experienced these problems ??? what should i do ??? im so frickin upset.
