Ok ok, I love the phone. Been following this forum. I have the latest DI18 update. Use the airplane mode toggle and stop DRM after reboot. I use DCswitch to toggle 3g when i want it. All background updates, emails and syncing are turned off ( I do them manually). i bought two extra batts. and charger. Use Timeriffic to auto airplane at night then on in the am. Yet at night in aiplane mode for about 8 hours I lose 6-7% of battery. Question is= Is there a simple app that can tell me what is using my battery? I know about the built in battery status but it not very detailed. What could use 6-7% while sleeping? Or is it sleeping and how do I tell? BTW BT, WiFi 4g ect.. are all turned off. TWS is usually low 0-13%.
