My battery seems to do alright but one thing that has really been bugging me is that every time my battery gets to 30/20% it dies almost instantly lasting no more than 15 minutes from normal usage (texting, checking email). Is this normal or is mine a bad battery or a battery gone bad rather? Thing is the battery lasts a long except for the last quarter of the battery. I've never seen my battery hit any values below 20% except 5% which is when it turns off immediately after. Call for a replacement battery or is this normal? Do i have to reset my battery or something?
