Strange thing happened with my phone over the last 2 nights. First, the battery level was about 95% when I went to bed and was at around 50% when I woke up 7 hours later (Phone was on but not left on charge). Last night it was at 49% and this morning it had turned off due to a drained battery. I'm happy with the battery life as I get 18-36hrs depending on usage, but this recent drain is not normal. I usually lose between 5-10% over night. I know there are a number of possible causes for the increased battery drain and I'm not asking for suggestions. What I need is something that will tell me what app is draining the battery. I want to identify the cause. I have spare parts but I don't think the battery info is provides can identify an individial app. EDIT: Just to clarify, the battery drain is fine during the day, it's increased overnight for the last 2 nights with the phone on in standby.
