Re: Dialer stays running in the background (HTC Inspire 4G)
The battery usage breakdowns what processes have used battery since the last time you charged it. Its not a list of active processes.
Also, the way Android works, just because a process is in memory, it doesn't mean its draining the battery. It will only significantly drain the battery, if its a process that is trying to do something in the background, like download data. Most processes are just "frozen" in memory in case they are called up again in the near future (they open faster that way), or until the memory fills up and is needed for something else (in which case Android will auto kill processes based on its own system of priorities). In Android, having memory free does not necessarily save power or increase performance, like it does in Windows.
