I have a question. There are two Power Saving modes in Android Lolipop:
1-Standby Intelligent Power Saving (where there is a toggle to turn it on and off under Power Management Settings)
2-Battery Saver Mode (where there is supposed to be a toggle to turn it on and off under Power Management Settings. But I can't find it and conclude it is missing?).
For #2 above, since you can't toggle it always seems to be on and kicks in when your battery drops below 15%----you know this when you see organe bars at the top and bottom of your screem.
Do you have this problem too?
