@Copernicus: I would like to check with you on a problem I have. This has happened twice to me and I am not sure if Pierogi is the culprit. I have a fully charged battery, use Pierogi and quit the program. When I check my phone 2 hours later, the battery is in the red and almost flat. Happened twice to me on two different days and the only thing I can think of was Pierogi. Other days, the battery is fine. Do you need any more info from me?
