Hi to all! This has happened several times in the last days: I turn off the phone before going to sleep, and, when I turn it on, the battery has discharged. Yesterday, I turned it off and today it has happened the same thing: I checked the battery status and it said the phone has been on for 18 hours, while I just turned it on! Once, it has even happened when the phone was turned off and connected to the battery charger. So, I guess it wasn't actually charging the battery. Anybody ever had the same issue?
