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

I love Android.
I think the customization is great, and since v4 it's smoother and feels more responsive.
There are LOTS of apps and it's better than iOS.
But i'm sick of the battery issues.
I've always loved trying new features, ROMs, apps, hacks and whatever.
I now have SGS3 and it's my third android device, and i've installed ROMs dozens of times, even on my friends' devices.
One thing that always kept me alert is the battery life - the maximum I can get from my battery is around 30 hours with my usage - 1/5-2 hours of screen, ~45 minutes talk, lots of standby.
But every now and then, my girlfriend, my dad, my aunt or my friend ask me 'why does my battery drain so fast?'
Sometimes its google maps.
Sometimes its mediaserver/media scanner
Sometimes - and only I can see it cause they are not familiar with tools like BBS, it's gsf (Google Services Framework).
The point is, when you have an Android device, you need to check the battery stats every now and then to make sure nothing is unusually heavy on the battery.
I am currently experimenting with ParanoidAndroid and AOKP, which are faster and more responsive than omega/stock.
Yesterday i went to sleep (6 hours) with 25% battery (after it lasted 15 hours) and I turned off the data connection and the wireless connection.
I woke up after 6 hours (lucky..) and I saw my phone if off. after I connected it to the charger and turned it on I saw mediaserver decided to wake up in the middle of the night, after It almost did nothing during the day, and worked for 5.5 hours until the battery died!
Today I unplugged my phone and in 1 hour of standby 10% of the battery were gone, I checked what happened using BBS and saw gsf again (that GTALK_SYNC whatever wakelock) was draining battery, after I thought I fixed it yesterday when I disabled app data and browser sync in the google account sync options). I rebooted and now it seems ok again, the phone is back to ~70-80-% sleep.
I want to emphasize that I don't like all the stupid battery tips that tell me to castrate my phone:
turn off wifi when it's not needed, turn down the brightness, lower the screen timeout, disable sync (wtf? but its a smart phone, I WANT push notifications!) and that sort of things.
I KNOW I can get >24hours of battery without disabling the basic features of my phone.
And the draining battery processes that I mentioned earlier can suddenly appear even in a stock ROM, so I don't think it's PA or AOKP's fault.
What I want is that google will finally build a supervisor entity that will check what causes an unusual battery drain, check if it makes sense, and disable that cause!
It's absurd that google maps application comes with default 'enable location reporting' that constantly drains your battery and for what?? google maps doesn't run in the foreground, why the hell will I want that background location reporting draining my battery? and if so, why do you put this option enabled BY DEFAULT? The average user doesn't know this sort of stuff, and get only 10 hours of battery out of a device that should ideally provide ~30 hours!!!
Just wanted to let it out of my system...
And to get useful battery tips if any...
I recently installed LS 4.0 on my Razr Maxx and noticed on my break at work i was at around 35% battery, then 2 hours later when i got off work i was at 3%, in that time i didnt have any apps open so the drain dosent make any sense. I took a screenshot of the battery graph for reference: http://i.imgur.com/MyUDnNT.png
As you can see on the graph it randomly drops off there and then goes down at a pretty brisk pace. I wasent using the phone from 6pm to 8pm, right around the time it dropped all that battery.
Could this be due to my battery just dieing out or is it possibly a issue with the rom?

Please describe more information like:
1. was your network set in 3G? LS battery isn't really good with 3G
2. what number of app you are using? social media apps that always updating their data i.e google+, fb, etc --> would increase data usage when they synchronize.
3. please check whether your razr went to deep sleep.
Solution:
1. Set to 2G always and go to 3G if you want faster speed (download the 2g/3g toggle widget for L)
2. Uninstall those app if you're not using it or limit their synchronize routine by the app itself or using profile in Tasker (advanced method)
3. you should installed wakelock monitor app from Play Store
If battery drain were persist when you have done those troubleshoot and solution, you should try to calibrate your battery (leave it shutdown automatically after reaching low level and then charge it until 100%, go + 1 hour to make sure, go to recovery to check the % and then boot to your system and calibrate using calibration app from the Play Store).
Last one, if calibrate doesnt work, then the battery might be already dropped.
Also do check that location services etc are set to power save mode.
Use an app to check wakelock and disable that annoying app.
or may be you are right... lets hope not for your own wellness!
I also remember having that problem when I was on cm12. After my battery dropping insanely low, it kept long before the little juice left in it run out.
So i thinks its something with the 5.0 ROMs

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.
Hello forum,
background info:
I have a rare Pansonic Android 5.0.2 phone (DMC-CM1) with an excellent camera, what is the reason why I want to keep this device.
There are NO custom roms available and no info about key combinations on how to get into stock recovery mode. I can go there with adb of course.
I found a key combination to get into fastboot, but Wiping cache/data to reset the device apparently did nothing, even if wating for hours. It seems as well as if Panasonic tampered with the stock bootloader :/ This is why I had to send it to service (adb was not enabled before).
They reflashed the device with 4.4.4 and I installed the updates to 5.0.2 OTA. Everything seemed fine until...
present problem:
...now I have a strange battery drain. Bevor I sent it it, I had about 2-3 days usage time with average usage, a little messageing, a few fotos. I do not use the phone much.
Now I get a maximum of around 16-20 hours out of it while it is just resting on the table. It also gets warm.
what have I done so far:
- I rooted the device and installed better battery stats from the forum here. It shows around 8-10% usage per hour. Before the problem showed, I had 1-2% usage.
- I uninstalled EVERY own installed app and even booted into safe mode -> same problem
- I disabled all google app packages -> same problem, but improved it a little
When I check the battery via android settings, it is telling me that "android-system" is using >20% of the battery. In active apps I can see this app is running the fast dormancy service. When I kill this service and force the complete app to stop, it gets _a little_ better, around 5-6% usage.
I recently killed forced stop on all services that where not qualcom or seemed essential to me and disables wifi and bluetooth and over night usage dropped to <1%/h, which seemed the problem could lie somewhere with services.
However using adb shell and pulling "top" info, I dont see a process using much CPU.
What else have I noticed, which might be unrelated:
-After charging I see a 100% wakelock from qpnp-charger, that disappears only after rebooting. Might indicate that something with qualcom is "wrong".
-I set wifi to be _never_ be running in sleep mode. Better battery stats is telling me, that wifi is 100% of the time running, even if I can see the symbol for wifi is not showing and comes up a few seconds after I wake the phone
You can see, I might need help on how to identify the problem here.
Any hints, tips, advice?
Please excuse my "messy" english, it is not my native language.
regards
Stefan
