Re: why did my batter just die
Welcome to Android Central! How much time passed between when it was 45% and when it was 1%? Were you able to take a screenshot of the battery stats at the time? Sudden battery drain like that is usually related to some app that starts malfunctioning, keeping the phone awake unnecessarily, or perhaps performing some CPU-heavy process that it shouldn't be. The battery stats can help you figure out what was using the most battery during this time. The next time this happens, remember to take a screenshot by pressing the Power and Vol Down buttons at the same time, and then post the photo here.
