I have not been happy at all with my battery drainage. I have not had much time to investigate and hopefully remedy.
Take today-- I charged the battery to 100%. Checked a couple of things and downloaded CurrentWidget-- now at 97%. I activated a streaming music app and plugged in my earbuds. An hour and 45 mins later it warns me battery is down to 15%. I have done nothing else but listen to streaming music. When I checked Battery Usage, Display usage was at 60%, the music app was at 4% and everything else was single digit percentages. The screen was never "on", so what comprises display battery usage? I saw gots2beme's great post and I did download CurrentWidget but was not terrible impressed with the info on Spare Parts. I was looking at SystemPanel instead. Anyone use that app?
Anyway, in Display settings:
I do have Auto-rotate screen checked. (I read a lot)
I have had "All animations" check but have now checked "some".
For Brightness I have tried "auto" and have tried 40% but noticed no discernable difference.
Screen timeout is 30 secs.
Notification flash is for email and voicemail only but I rarely miss a call and today had nothing happen while listening to streaming music for all of 105 minutes.
So, what sucks juice in "Display Settings"???
Thanks, this is a great community!!
