Does fingerprints scan, dt2w, pocket detection, prevent accidental wakeup affect bat - Lenovo ZUK Z2 (Plus) Questions & Answers

Hi all,
I'm new to Zuk Z2 and currently @crdroid Nougat latest. I have 1 question about battery life (standby)
Does these features affect battery: fingerprint scanning, pocket detection, dt2w and prevent accidental wakeup affect battery?
I have all these features turn on but wifi, data, gps and sync turn off and lost 6% battery overnight. Is this normal?

I have all these feature turn off and lost 1% battery overnight. All those feature require sensor actively working all the time so they will obviously drain more battery.

Dt2w causes lots of battery drain

LGE Knock-on Proximity Sensor - impact on battery

Hi All
The LGE Knock-on Proximity Sensor is taking over 5% of my battery and is awake 5h46 (total on battery is 7h51 so far)
Something is killing my battery recently, I'm down to 56% after 7hr with only 1 hour onscreen time. Android system is taking over 10% total (LGE Knock-on Proximity Sensor is part of this).
Can anyone check their phone to see where LGE Knock-on Proximity Sensor ranks on battery drain?
I have recently installed quite a few things which mayby causing drain by most of Greenified, the following are not
Tapatalk
XDA app

Google search is causing a lot of wakelocks also. I dont know if this is normal? I have google now but only using Cell tower location.
Google now is usually the culprit of a lot of battery drain, I have learnt not to use it and disable it/freeze it.
But that's personal preference.
I don't use knock on, so can't comment on that.

After I turned off full GPS and network location settings and switched to just network Google now has stopped taking as much battery.
It's knock-on which is consistently high
my LG G pro 2 has knock-on feature, but without LGE Knock-on Proximity Sensor... no issue on battery usage....

[Q] Need help - Bluetooth, MM 6.0 stock/fullmics and battery drain

Hi, got problem with battery drain with bt turned on.
I'm using miband 1s, baterry drains really fast when bt is turned on.
miband does not use bt all the time (battery works almost 30days) but it happens only on MM (checked stock 2 times, all resets done few times, after that checked fullmics 3.5 and 3.7).
here are screens.
Any ideas and questions are welcome

drive.google. com/file/d/0B4rBUUVDHHYQTEc2RW1xdHJ1STh2MVVPQmpXQmJpVFduS2VB/view?usp=sharing
drive.google. com/file/d/0B4rBUUVDHHYQdXdhT2dSTDRtWGpzWFpFemNJbzI0dEthRkFn/view?usp=sharing
At those screens battery info reports Bluettoth settings, but usually it's just Android OS around 20-30% when bt is on.
Ofcourse doze does not work when bt is on, when turned off - works great.
Is there any app that checks wakelocks in MM?

Bluetooth extremely exhausted battery even without any connection

For some reason, if I do not toggle off BT, it drains my battery. Look at screenshot for last night

I do have the same problem. It only started after the January security patch update.
Now, the BT battery usage is highest, and it drains the battery even if not connected to any device...

Battery drain issue from AoD service with no AoD enabled

Hey guys have been having pretty bad battery drain from my new S20 4g Exynos. My old S9+ has better battery life than this.
I have installed GSam and it seems apps are using ~95% of my battery in basically 100% standby. The largest is com.samsung.android.app.aodservice which is the always on display. I have already turned off all AoD services as well as the fingerprint icon when screen is off. Despite doing all this I can still put my finger on the screen after the phone has been locked and it unlocks with my fingerprint. Is there another setting I am missing to turn off, is it even configurable? Or am I having some sort of glitch?
9GAG as well was using lots of battery even if I had it in deep sleep and never even opened it after a reboot, so I have uninstalled that for now.
Looks like a glitch, either disable the service or wipe the phone.
I'm assuming the battery usage is the glitch you are referring to. If I disable the service and re-enable would that fix it you think? Our I would need to reset? I spent like a week getting this all setup already.
Also for the unlock without turning the screen on or waking, is that normal behaviour for everyone else or is it a setting/glitch?

I am having the same readings from gsam. But Samsung battery stats say AOD used 3% battery. Not sure which is wrong

Consider setting GSam to record battery usage since full charged instead since last unpluged it's better.Because you get real usage and screen on time for only that 100% of battery.

"Enable more stats" in gsam.
There is description how to enable it.
It is not aod that is draining the battery, I've got the same issue, I uninstalled AOD using ADB it didn't change anything

Do you have AoD enabled though? I have everything turned off and it is still chugging my battery
Package Disabler Pro, disable the service, no root needed either
So as an updated I disabled all AoD things with CCWSE and AoD is still chewing battery in the background as well as CCWSE now.... sigh

That is bizarre. Re-enable AOD in CCSWE, then use CCSWE to wipe AOD data (tap AOD icon, look at bottom of screen and tap "Wipe data") and disable AOD again. Restart phone and leave it alone for a few minutes to let GSam battery collect data. Open GSam battery, tap the triangle/delta icon at the bottom of screen, choose "Since screen off" and see if AOD/CCSWE is still consuming battery.
So I did a factory reset and same thing happening even, without installing anything but GSAM and giving it permission. Turning off all AoD options didn't do anything. However when enabling power saving and ticking the option to turn off AoD it seems to be dropping the battery use from the service like crazy. Will need a few days of testing to see if this can fix the problem. However leaving in battery saving means I can't enjoy anything above 60hz refresh.
I noticed AOD consuming more battery following ADT1 update. I've never used AOD and it was always low on the GSam battery monitor list. But now it is #4 on the list, using 4% battery even when "disabled".

I'm still on ATD3 and have between 1.2-1.7% on Gsam, depending on how much notification i get .... using "Tap to show" on AOD along with aodNoti..app...

Main AOD service can not be disabled. There is no option to disable. This problem is related to fingerprint tracker while the phone is in standby. It's always on because you maybe need to unlock the phone any time. If you disable online fingerprint scanner (com.samsung.android.app.aodservice) then you loose fingerprint scanner while the phone is in standbye. So you should first wake on your phone from standby (by double tab the screen or push the power key) then put your finger on fingerprint scanner.
To disable AOD, Just Enable USB debugging mode then enter command:
adb shell pm disable-user com.samsung.android.app.aodservice
note: If you got successful you should receive (Package com.samsung.android.app.aodservice new state: disabled-user)
That's all.

Default camera app battery drain

I recently bought this phone, I updated everything system, apps......the camera keeps running the background, even when I have closed the app.....
Problems does go away if I clear data of camera app...but I don't want to do this everytime.......I bought the same phone for my mum, and same thing is happening there too, on top of that in her phone chrome is consuming a lot of battery even when the phone is idle...... please help me out
Also I did try that restrict background activity but that option did nothing and the time on "while in background" kept on increasing
P.S location was off.
Never happened this problem to my European LG G7 Thinq (LMG710EM).
Anyway you have to turn off "background activity flag" to stop background activities of any app (do it for each app).
But consider also that the 7% of battery may be consumed just in that 11 minutes.
Shooting photo consumes a lot of battery...
After a week I have figured that you need to compromise on 2 features to get a good battery life ......1st obvious one was always on display, after disabling that, battery life increased a lot, but my idle battery drain was still 1-2 % per hour with wifi turned off.......2nd I disabled the double tap to wake (knock on) and hallelujah! Now on idle it barely drains 1-2% overnight.....
This is a great phone but lacks in the battery department...I mean, I don't mind disabling aod but double tap to wake is a great feature to have...too bad it drains the battery like hell
