[Q] Call standby and WLAN eating battary

Hi, got my e7 2 days ago, updated to kk.
Everything working but call standby and WLAN eating battery, screen on for 3h 10min(consumed 10% of battery) and after 12h I have only
10% battery left. The phone wasn't awake while screen is on so it is probably not an app keeping the phone awake..
So .. wifi is always on(on battery stats, but I turned if off for 3h) and even so it shouldn't consume 28% of battery.
Standby consumed 29% of battery! But always got full signal and talked just for 10-15min.
I've done root with 360root and remove(suspend)some apps with 360root.
Any suggestions?
Thanks.

High cell standby

I've seen this all over the place with Lollipop, and it now seems to be affecting me.
I have Greenify installed, Amplify takes any big wakelocks, no google now, location on battery saving. No abnormal wakelocks. But something is keeping the radio active all the time. I've even downgraded to 2G in case it was that.
Phone was charged at 100% and in 4 hours cell standby has a 'time on' of 2h 34m.
I can post battery stats later in the day but the same happened yesterday. I can barely get 3 hours SOT.

Huge battery drain: Awake screen off

Hi
Brand new phone here, not rooted and fully stock.
During last three days I noticed a huge battery drain overnight, so I installed Better Battery Stats. Being not rooted I don't see many info but one thing is clear: after 6h being idle, I have lost 17% and BBS shows one single line as per attached screenshot.
Any idea what's going on?
Thanks
try turning off wifi and anything that syncs constantly. go into settings, battery and see what it shows. no need for an extra app.
????
I don't want to turn off wifi at night.
With my edge+ all was remaining on and I would use only 4% overnight
I have the same problem. Go to sleep at night and wake up 7 hours later with 40% drain during the night. I don't use wifi.

I've had this phone for a week, and the first 3 days all was ok, but during the last 3 nights I am experiencing this huge drain overnight.
Problem is I am not rooted (and am not willing to root right now, till Android N comes) so I cannot really use wakelock detectors to see what's going on.
Phone is set up exactly like my Samsung S6 Edge+ and this one drain max 5% overnight.
Again go into settings and battery and see what is being used
Ok tonight I'll check
Here it is.
Unplugged and left 6h idle overnight with wifi on.
Lost 12℅
I cannot understand what's going on

Tonight lost 20%
Please note this happens only at night while phone is idle.
During day battery seems OK and wifi or idle do not show up in battery usage.
Also from the screenshot I see only 1% and a very low mA usage, so I don't understand why I lose so much battery when nothing is going on.
Is this really a problem? Your phone is losing between 2% and 3.3% per hour. That doesn't seem that bad. Mine is around 6% during the day (I have it plugged in during the night).
2% per hour in doze at night is a huge problem

Yeah, that kind of drain is an issue. I lose like 1% every 6 or 7 hours overnight with phone in doze with 2 maint. cycles

Battery drain

HI,
I think my battery have to be replaced. Accubattery says it's capacity is at 2800 mah only right now.
But I also saw the battery drain is quite large especially when screen is off. 85% of screen off time is under deep sleep but I see that the drain is still at 2% per hour (about 100ma)
I observe a battery level drop of about 20% overnight.
I'm running LineageOS 18.1 + Gapps. at the moment. I don't use fancy apps, just standard gapps, Gmail, Maps.
So my question is : Is this level of drain normal for the device ? If not what could I try to solve this problem ?
I disabled the digital wellbeing app and now off screen drain is much lower.
