Hello.

Z3 D6603, Lollipop stock, not rooted, Central Europe 1, unlocked. - Clean Flash 5 days running.
Wifi - on/Mobile data - always on (3g only)/Location on - high accuracy/Lifelog - on/BT - off/Stamina mode - on (all the bells and whistles)/Smart lock - off/ Sync - On/ Brightness - 25% Auto.
Normal usage: Chrome browsing, 9gag, fb, fb messenger, whatsapp, 3 mails on sync (gmail and 2 other on stock email app), about 2-3 h of talk time, Music - about 1 h /day, about 10 minutes of Clash of Clans /day, and auto-backup via Qnap Nas app only on wi-fi at home (morning and evening).

On KK - used to get about 4.5-5h SOT / day - would plug in at about 24-01 to charge with 10-13%. Stamina worked accordingly - Screen off - Phone sleeping/no notifications - Battery predictable
On LLP - i get from 2h to 6 h SOT / day - have to plug in at 22 to charge with 5-10%. Although stamina is on, i still get notifications while the screen is off, and the phone stays awake for a long time. - Battery unpredictable

In general, the phone stays awake as long as it is on mobile data, when it's on wifi, it behaves like it's supposed to.

By comparison, my gf has a Z3c, same type of usage, same network. Dirty flash - The phone behaves as it should - awake time normal - battery predictable - about the same like it was on KK

My question : Anybody else encountered this problem? Suggestions to fix these annoying wakelocks? Is it a known bug? Would a 3rd clean install fix it?

Thank you, and best regards.
