[Q] Asus fonepad battery drain fast - Android Q&A, Help & Troubleshooting

Hi all,
Recently, my fonepad battery suddenly drain 30-40% faster. In other words, it completely drain in 13 hours without any talk time. This happened after my house have a sudden blackout during phone charging which at that point is 85%. I had tried to reset the phone (via power + volume up button) now still fail.. Attached are the screenshot from battery widget, settings and wakelock detector.. Any idea ??

Use BetterBatteryStats to determine which process keeps your device awaken. BBS will give you more information than Wakelock Detector.
The main culprit for you seems to be the alarm_rtc wakelock, which handles alarms (when an application or process checks periodically on something). So maybe your device is trying to sync something but fails to do so and thus keeping your device awake. You could try to disable all apps that sync data one by one.

[Q] nfx_log_service draining battery

The tablet has been working correctly for 2 weeks, but today the battery has drained from 50% to 8% in just 8 hours with the tablet in sleep mode.
I've plugged it to the charger and I've opened the battery usage settings screen. There it was an app called nfx_log_service with standard android icon but the tablet FC when I try to open the app details.
Anybody has a clue what is this app?
I've done a power off - power on of the tablet hoping the nfx_log_service does not appears again...
It happened again yesterday. This time I recharged the tablet as usual leaving it on and today the battery consumption seems ok.
I've installed Better Battery Stats and it shows the nfx_log_service doing lots of wakelocks, but there is no process name or uid to identifiy where it comes from.
When I received the tablet it updated itself to Android 3.2.1. Do you think it's better to do a factory reset to start clean from 3.2.1 or it will not make any difference?
I noticed the same thing...it will always FC if i try to open it. No clue what it is

[Q] Battery Suddenly Dropping without Usage

So I was on Sensation ROM without any issues. Ran it for months. Could easily go 36 hours with light use - not much drop when not in use (i.e. 8-10% overnight).
Suddenly, it started to drop like 10% an hour out of nowhere. Did this for a few days. I decided to try another ROM (Resurrection), wiped and tried again. I restored missing apps with data (which might be the issue) and it didn't seem to help. Unplugged 2 hours ago at 100%, and it's at 80% already with about 5 minutes of use.
CPU SPy shows 73% in deep sleep, which seems decent and 11% at 200MHZ
Better Battery Stats are confusing to me, but here are the items at the top (red bars showing):
Under Partial Wakelocks - AudioOut shows 4.7%, The media scanner service at 1.5% and some more minor stuff.
Under kernel wakelocks: BT Low power at 4.7%, Secril_fd_interface at 2.9% and multidp at 3.1%
Processes: kworker/0:1, kworker/0:3, kworker/0:2, kworker/0:0.

well the deep sleep should be int the 90's when not in use
looking into ur BBS stats u have audio wakelock and media scanner wakelock
which r draining ur batt thats why its under 200 mhz @ 11%
so please delete data cache of media scanner and also uncheck all ur audio settings under Systemsettings>sound then reboot after that wait for some time by not touchnig ur phone and after that check deepsleep with CPU spy it will be over 90% that ensure better batt life

Have you enabled BlueTooth?
Disable it if you do not actually need it.
Disable GPS, Bluetooth and WIFI when not using it.
Thanks for the help. I checked this morning and the phone is spending most of it's time at (50% or so) 200Mhz when sleeping, so it looks like it's not sleeping properly. I can't find anything called "media scanner" in apps or titanium, so I'm not sure how to delete that cache.
I checked BBS against today and it shows Audio_out as the leading partial wakelock, but how do I fix this? I unchecked everything in audio and rebooted and it didn't seem to help.
Second wakelock is network location active collector. Again, not sure how to fix this (is this location services?). I deleted data under "Network location" in titatium.

clear media storage data using titanium backup
its meda scanner
There is no app or anything called media server in Titanium or in the apps. it seems DRM protected storage and media manager might be it, but i cleared that data and the music disappeared and then the phone eventually froze and would not boot.
Any ideas? I re-flashed the ROM and it didn't fix it. How can this be an issue on two different Roms?
Thanks.

[Q] BetterBatteryStats reports 'gpsd-interface' killing battery on Galaxy Player 5.0

Hi there,
I've had my Galaxy Player 5.0 for over a month now, and it's been exhibiting a weird battery drain problem. I have everything set up to drain as little battery as possible when the device is sleeping. I've got auto-sync off, Juice Defender Plus to automatically disable Wi-Fi... it's working beautifully most of the time. I can go for days without the battery draining at all when I'm not using it. But then it inevitably hits a point where I turn it on and lo, like half the battery charge is gone. I check BetterBatteryStats often to monitor this problem, and it usually shows about the same awake time as screen on time, which is what you'd expect. When the problem kicks in however, the device shows hours and hours of extra awake time.
Two new kernel wakelock entries appear at the top:
gpsd-interface
GPS
Those account for pretty much all the extra awake time. I can break these wakelocks by turning on the GPS, starting Google Maps, letting it read my location, closing Google Maps and finally turning off GPS again. I never use Google Maps or GPS the rest of the time, but these wakelocks keep coming back every few days. I've searched everywhere for any mention of "gpsd-interface" and I found nothing.
Any idea how I might be able to fix this?
Thanks, Nir

[Q] Battery discharging (wakelock) - Lenovo A1000 - 4.1.2 Jelly Bean

I have noticed weird behaviour of my Lenovo A1000 tablet and I would like to find out is it normal (I was finding similar topic but I've not found).
When I charged device fully and unplugged it, battery discharges slowly by about 24 hours. After about 12 hours from disconnection battery is 98%, next 12 hours - 95-96%. Afterwards, it discharges much faster, for example - before night it is 95%, in morning it is 83%. Sometimes it falls 20%.
I installed Wakelock Detector. By first 24 hours, it says that there was 1 screen wakelock: Android System - keyguard triggered several times and it lasted several seconds (always less than 20). When my battery is being drained, WD says that this wakelock lasted above 1 hour.
Is it normal, or something drains my battery, or battery sensor/indicator is low quality?
Tablet doesn't have 3G modem; Wi-Fi is turned off when device is asleep; turned on sync: Gmail, calendar, contacts (photos, G+, Facebook, Twitter etc are turned off); positioning is turned off (GPS, Wi-Fi); Google Now is disabled; all apps are up to date.
Screenshots from WD (I can't post links/images)

OK, I've done some tests. Battery is drainded when Wi-Fi is turned on and lost connection, even when it is set to switch off when asleep. When I make device asleep and turn off my Wi-Fi router, tablet is awake during that time and it can't go into deep sleep. I uninstalled apps like Facebook etc. and it didn't help, hence it is not problem with app sync (unless Google services).
Does anybody know where is the problem?

Battery drain ONLY when smartwatch is NOT connected

I tested this with different watches and different apps and the result is always the same - there are almost constant Bluetooth wakelocks (BetterBatteryStats reports over 50%) and hence battery drain - but only when the watches are NOT connected. When the watches are connected - everything is fine!
I am running rooted Android 10 and tried to manually put the smartwatch apps in the Sleeping apps and Deep sleeping apps (Device care > Battery > App power management) but the result was absolutely the same. Only when I uninstall the apps, the Bluetooth wakelocks and battery drain stop.
This is driving me mad because I have to keep the watched turned on at all times, because otherwise will face battery drain. Has anyone had the same problem? Any idea of how to solve it will be much appreciated.
Can you not simply set it to go to sleep when not in use? (Through >device manager >battery)
I know it's possible because I had the same problem with my girls phone a while back, just can't remember how exactly I fixed it, but it turned out to be pretty simple...
Thank you but I did this as I have described and it desn't help.
