I started noticing this problem outside in the cold. I didn’t take much notice of this problem as I thought this was because of the cold. Now when my phone is indoors and at room temperature the battery might randomly go down to zero and it turns off. This is very annoying now especially when I’m in the middle of doing something important. In addition I don’t always have access to a charger so if I want to call/text someone I can’ because my phone has no battery. I’m already considering purchasing a new phone at this point. What might be the problem?
Is your phone rooted? If not download AccuBattery and see if it shows some errors on your battery. If its rooted you can get some better apps for showing details about your battery
