[Q] Battery weird issue - Galaxy Note II Q&A, Help & Troubleshooting

Hello everyone!
I have been using different Roms lately and the durability of the battery is pretty bad. Usually people say the battery should last at least 12 hours in normal use, in my case it works on use only a couple of hours (With screen off it can be on about 10 - 12 hours). And the weirdest thing is that I tried to drain completly the battery of my phone, after I got it I turned it on (With charger connected) and what happend was that I was into the window you get whenever you install a Rom or turn on the phone for first time (configurations, apps and the order of the things didn't change) and without even 5 minutes of charging my phone says it has 67% of battery. I've already tried different monitoring apps and also battery calibration apps, there was no improvement at all.
Any help or suggestion will be accepted.
Thanks for the help.

First flash stock ROM via ODIN. (Uncheck auto reboot) Manually reboot to recovery. Wipe data/ factory reset and wipe cache.
Use the ROM for a couple of days without installing extra apps to check battery performance. If phone battery does not last for over 8 hours on normal use, buy urself a new one.
Press thumps up if you found this suggestion helpful.

[Q] incorrect/missing battery usage information

Hi all,
Here is what happens.
I charge my phone (N7100, 4.1.2 stock rom, rooted) until it says "remove charger", I remove the charger, then I use it for say 20 minutes. When I reboot the battery usage counter resets and starts from zero. So I can only get the stats since boot.
Then I continue to use the phone for two hours, reboot it, and this time the counter shows one hour of usage, missing one hour
I continue to use it this way, then reboot it after 3 hours, this time the counter continues correctly from previous time.
There is no standard pattern I could make sense of (i.e. percentage, usage time). I never had this problem in my previous xperia ray wt. ginderbread. I bought this phone (N7100 international version) a week ago, updated when I saw the notification, then did a factory reset to start clean, rooted and flashed TWRP with note2 toolkit.
Everything else works a like a charm.
Thanks in advance for any opinion and forgive my English if I took a lot of your time to explain a simple problem.
Hi again,
I have found the exactly-same problem discussed and left unsolved last year in this thread in xda:
http://forum.xda-developers.com/showthread.php?t=1348438
The battery stats are not kept "across boots" as google describes in the function of batterystats.bin.
Should I wipe the battery stats in twrp after charging to 100%, or is there anything else I can try first?
(e.g. changing certain permissions or editing a file)
Any help will be appreciated.
It resets battery Stats whenever it reaches full.
You can try reseting it manually for once.
If your recovery has the option to do it, then it is very much outdated, I would recommend you to update to the latest ASAP.

[Q] N5100 Battery Life

Was skeptical about the N5100 battery life since it only have 4600mAH battery.
Now that I have bought it, it seems my worries are confirmed.
I'm running stock rom, only rooted it without other modification.
Installed and have greenify running. Not using any sim card, only using it on WiFi.
Playing a video using MX Player, drained up about 20% of battery for a 45min video. That's rather heavy imo.
Normal browsing and reading forums eats up about 4% per 6min of use.
Is this normal? Or is it my battery has significantly degraded? Cuz I bought this 2nd hand 8 months old.
Btw the above test were with Power Saving mode(CPU and Screen) and screen brightness was at 25%~30%. Currently on 4.2.2.
And does using the S Pen eats up significantly more battery?
Thanks in advance for the feedback.

Do a search on battery and charging by me, in the Q&A threads. I won't repeat myself here, but I go into how to correct drain issues. Many developers will push their apps for calibration. The real trick is discovering what is doing the drain. I have seen for myself how one app can do a lot of damage with media. Normally I get 12% per hour on battery usage while Miracasting Netflix to my tv, and about 10% on normal usage with WIFI always on. I have MXplayer and a bunch of apps as well running so I am not going to get the same power savings as with a cleaned up stock ROM without any apps, what would the point of having a tablet if that is the case???? I guess peeps like to show off when it comes to numbers. I like to show off when it comes to usability and function without all the apps get in the way.
my battery stats
I'm running CivZ-FLEX-BEAM-REV3.6.2 ROM.
Installed and have greenify running. Not using any sim card, only using it on WiFi, even off the WiFi before I off the screen.
Even use underclock to 1.2Ghz cuz only used for normal browsing, nothing intense that require more power.
Here's my battery stats:
Is this normal? Or is it my battery has significantly degraded? Cuz I bought this 2nd hand 8 months old, now 9 or 10 months already.
Now considering should I replace the battery or just get a powerbank to help.

From what the graphs show... it looks like the battery could be going bad, as there has some that say Samsung is aware of bad batteries in some units. You could contact them, but you will need to un-root if sending to Samsung for repair.
Since you are rooted, I suggest installing xposed framework and install Wanam DVFS Disabler for Xposed. It is a standalone utility from the complete Wanam xposed app. Once installed make sure both xposed is functional, and the app in xposed is enabled. These apps act as a separate process from the OS. So installing them requires user interaction for activation and updating, along with a reboot most of the time.
Once they are running... it is best to turn off the tablet for 1 minute and then plug in the USB charger and wait til it is showing 100%. Then turn on the tablet. You can unplug the USB power cable and wait 1 minute, then plug it in. Take note if the charge takes less than a minute to get to 100%. If it takes a minute or more... you will need a stop watch, as it should take about 15 to 20 seconds to go to fully charged, unless you have music or media running at the time. If it does charge quick, you can then disconnect and do another days worth of use and check your stats. Hopefully disabling DVFS will cure your issue if it is not battery related.
As for unrooting, make sure you do a clean uninstall, and have any apps that require root uninstalled. If running triangle away uninstall that as well. You may have to check within the apps settings to make sure you uninstall properly, as to uninstall from play store or the system may not properly remove the app.
Updated Battery Stats
this is my updated battery stats, now I'm suspecting it maybe due to calibration problem?
My screen on time is now 2 hrs 45 mins, and for the last 45 mins it has been running on that last 1% of battery(but with screen dimmed, as brightness is automatically dimmed and can't be adjusted when below 5%).
Even until now the device haven't auto shut down due to run out of battery yet even though been running 45mins SOT for that 1%.
Calibration problem? I've tried calibrating using calibration apps, which I charged to 100% then press calibrate, but didn't help.

Sudden drop of more than 3% at any level after doing the DVFS disable and properly charging can be one of two things.
A bad battery, or bad charging cable. Yep, I have had two bad Samsung cables, one did exactly what is happening with you, and the other did a melt down at the USB connection on my tablet. If you have a good cable from a Blackberry or a Sony/Ericson device, you can try that. I have moved over to Sony Xperia cables, as they are pretty well built and longer.
If another cable does not solve your issues, I suggest unrooting and cleaning up rooted apps before having Samsung service your tablet. It very well could be a bad battery.
thanks for the reply, I think I'll just resort to sending it back to Samsung to fix it.
Now I have made a nandroid backup already, then I flashed stock firmware, so my device is now unrooted and on stock firmware, however my flashcount is still there, and now I can't run triangle away cuz my device is unrooted already.
If I were to root it, it'll flash custom recovery again then it won't be on stock firmware anymore.

Your unroot sequence was done out of order.
Set USB debug
Root stock rom with saferoot.zip
Install triangle away
perform clear of counters
Verify after clearing in about device that custom is not set.
If so make sure triangle away is set to clear and perform clearing.
Remove triangle away
Remove SuperSU through the settings, clear for reinstall.
To make sure everything is proper... do a factory reset.
Once those steps are done, your tablet should be stock and able to perform OTA or Kies updates, without any issues with counter and root.

[Q] 4.4.2 Battery Life issues - less than 25% total life compared to previous version

Hello, new to the forums here. I recently updated to 4.4.2 on my LG Optimus G Pro and I went from having a battery that lasted all day, sometimes two days to my phone being dead by the time I get home from work for the day ever since the update.
Two days ago I had 1hr18min of screen time within a 6 hours off the charger and the phone was at 15% battery life left. Today, I had 13 minutes of on screen time and at the end of my 6 hour shift my phone was at 40% and dead a few hours after I got home. I have GPS, bluetooth, NFS all disabled and my brightness set to 30%.
Any help would be greatly appreciated, I'm thinking of doing a factory reset and just not updating to the new version of android when it prompts.
Thanks

Get betterbatterystats and see if you phone deep sleeps. If not then check what the wakelocks are in partial wakelocks. If it's a kernel problem maybe you need to flash a different kernel.

i am running stock phone. it is not rooted or anything
Same exact battery drain problem. Im on stock e980 rom (rooted) with no custom kernel.
Gsam battery monitor app is showing the kernel as keeping my phone wake for the entire time my phone has been unplugged.
The problem seems to come and go though. One day itll be fine, but another day the battery will be sucked dry fast.

I'm running stock rooted for e980 and have pretty good battery life .... Try clearing Google play services data and rebooting ... Check and see what's draining your battery mol its pretty easy

I've done this twice in the past 3 days....
I'm sick of having to set up my phone over and over again. And this is a new phone too. I just got it Monday under warranty because my old phone broke.
It's getting annoying. I used to get 14-17hrs+ of battery life (casual use, usually ending the day at 30-50% too, so I never even reached 0%) with my old phone on Jelly Bean. Now with Kitkat, I get around 6 hours if I'm lucky! According to Wakelock detector, my phone is awake 85%+ of the day! All it points to is Kernel (Android OS). I see lots of Wlan_wake triggers too, so I suspect wifi, but even with wifi off, the drainage still occurs. And I only have a 2GB data plan shared between 3 people, so it's not like I can just use data all the time either. I actually NEED wifi.

do you have an SD card installed? Maybe you can try to remove that and get rid of all other media from your phone storage. Might be a media scanner problem? Or maybe you can try to disable auto sync, and check if Google play services is the culprit.

The media scanner usually shows up in the battery stats window though, and it isn't. I've had a corrupted SD card on my tablet once before and it caused media scanner to go berserk, but the Mediascanner entry appeared under Settings>Battery as the highest battery consumer.
In this case of my phone right now, it is Android OS in Settings>Battery. According to Wakelock detector, GSam, and BetterBatteryStats, it's more specifically Kernel.

Have you tried reflashing your firmware, instead of just doing a factory reset?
I assume you are rooted since you are using BBS and wake lock detector on KK. Why not flash a custom rom?

Hi i had the same problem as you but i started digging inside the system of the phone i found the problem but you will require root access. If you have root you have to delet a lib file tand it carrier iq wich run in background and drains your battery the file to delete is libiq_client.so do that and you will see an increase in battery life

I did this on Tuesday or Wednesday.
... I messed something up on my phone while trying to install a custom recovery, so I was basically forced to reinstall everything. I'm on stock ATT e980 ROM (on an E980) + root. I reflashed the Jelly Bean tot file and then did the OTA update with no apps installed.
On the phone that got warrantied, I had flashed the E980 kitkat backup (now has a flashable version too), and the battery life seemed to be much better on it for about a week, and then the issues started there too.
I just rebooted the phone into recovery and wiped cache and Dalvik cache. Many people on Kitkat are reporting that this helps, but only for about 2 days then the issue returns. Obviously, I want a permanent solution.

Yes, I'm rooted and I absolutely hate custom roms. They take out all the features of the phone that I originally bought the phone for, like Smart Screen, the IR remote (yes, I know it can be ported), and the quick memo button. Plus I used custom ROMs on my old SGS2 and they always caused me tons of problems. Crashes, overheating, random reboots, random SODs, etc etc etc. Plus I hate the AOSP feel. I know it's true Android, but I just don;t like it.

I'm still getting more than usual battery drain, but it is better now.
I just got a replacement OEM LG battery, so I will try that to see if maybe the battery is defective. When I got my phone replaced under warranty, they didn't have batteries in stock, so they just gave me back my old one and ordered me a knew one. The old phone was overheating a lot too, so maybe the battery is bad.
UPDATE: OK, MUUUUUUUUUCH better battery now!
I put in that new battery and "recalibrated" it by draining it to 0% and charging with the power off. Once it reached 100%, I let it charge an extra hour, unplugged, and started up the phone.
I also installed Qualcomm Snapdragon's Battery Guru. I set it up so that it's mostly managing app syncing, but I also set it up so that it will not rely on location services to turn on/off my wifi. I don't want to leave my location services on all the time. I don't know how it is on Kitkat, but on older Android versions (ICS and GB), leaving GPS on was a huge battery drainer! I still treat location like it was back then.
Anyways, it will take a few days for the app to learn my usage patterns, but it's already helping by making certain apps only sync when I open them, etc. I suspect that all the wlan_wake wakelocks are being caused by auto-sync but I'm reluctant to turn it completely off since i rely on it to sync my work schedule, calendar, etc between my phone and tablet. I just wish there was a system setting to allow auto-sync to run every X hours or something. I really only need the sync to run every 6 hours or so.
It's been about 35mins now with 6mins of screen time and the phone is still at 100%. A few text messages and the installation of Battery Guru too. This is normal and how things used to be. After a while, the phone will most likely go to 99% and then have faster drain, but it shouldn't be so rapid like before. Earlier today, after 30mins, the battery would be at at least 95% or lower by now! After a full day, the battery usage graph would should a 45 degree angle too! It used to be an almost level, very gradual angle instead.
I should also mention that for a while, I was using a Zero Lemon slim battery (3150mAh). I bought it because of all the hype Zero Lemon was getting here on XDA, but I really regret it now. I used it for 2 weeks (1 week on my broken phone and 1 week on my replacement) and the drain wasn't consistent, even after several calibration attempts. It lasted me all day though, but I'd be stuck at maybe 3% for like an hour, then while in deep sleep, the battery would "magically charge" to 6%.
After I swapped back to the OEM battery, I don't think I recalibrated, so I wonder if my phone thought I was still using the Zero Lemon.
I'm planning to return the Zero Lemon.
UPDATE2: It's been a couple hours now and the Android OS is starting to retreat from the #1 slot in the battery consumption list!
Screen is #1 now and Android OS went from 65% usage to 14%! :good: :good:
UPDATE3: :crying: OK, it's broken again. I didn't do anything to the phone, but when the phone hit 50%, I left it alone for 2 hours and the battery drained 30% while it was supposed to be sleeping. Android OS is back up to 80% usage!
Wifi on, Location off, Bluetooth off, auto-sync on. I'm trying auto-sync off today to see if there's any dramatic improvement.
UPDATE4: I might be on to something now. I noticed 2 things: 1st, when the screen is off and the phone is SUPPOSED to be in deep sleep, the back of the phone stays warm to the touch. It wasn't hot, but it was warm enough to be noticeable. 2nd, I had System Tuner installed yesterday but uninstalled it this morning. Despite uninstalling and rebooting, the phone was still draining battery fast (I still lost 25% in 2 hours today!). I noticed that System Tuner had added a script to System/etc/init.d, so I deleted that and rebooted. Now the phone seems to be sleeping (says so in BetterBatteryStats and WakeLockDetector), and the back of the phone is COLD to the touch when doing so. I took a shower today (I take fairly long showers too LOL), and then checked my email, and the battery life didn't decrease at all during that time while it was asleep.
Obviously, I need to test this throughout the day now, but this is definite progress, if not the solution.
Also, on my warrantied phone, when I had the Zero Lemon battery inserted, battery drain was high (battery's fault), so I installed System Tuner then too, trying to tweak the phone. After switching back to the stock battery, the drain remained, but most likely due to System Tuner's script.
Then when I got my replacement phone, I ALSO installed System Tuner and of course, I got battery drain issues! I factory reset, but did not install System Tuner, but the problem still remained. However, it probably remained because the reset doesn't remove system files, so this script was still in the init.d folder.
FINAL: I ended up flashing the stock ROM again (I used Eazy Kat 1.0 this time). My phone began bugging out on me. Random crashes here and there, mobile data randomly disappearing (no LTE/4G/3G at all), and worst of all, people were having difficulty hearing me during calls. Reflashing seems to have worked perfectly this time. *knock on wood*
FYI: The last flashes I did, I used .tot files to flash back to stock Jelly Bean and then updated to Kitkat via OTA.

I stumbled across this post and tried that fix. I'll check back in later to see what it does.

Battery suddenly draining rapidly.

My battery suddenly started draining rapidly earlier today. I normally get through a full day after charging overnight, but today the battery was down to 15% after 8 hours with the same amount of use as I do normally.
I let it die out completely since I didn't have my charger with me, then did a full charge once I got home. I took it off the charger and within 3 hours it is back down to 15% again. I have barely even turned the screen on except to check a few incoming messages.
I have just done a cache wipe in the hopes that it will fix itself. Is there anything else I could try? I'm completely baffled.
Well, i was facing same thing untill i did few tweaking like-
1. Go in auto start manager and ****ing close every useless social app(FB) they will suck it up
2. Choose power saver mode u like or use customized one
3. Do not use live wallpapers, well i use to change my wallpaper randomly every 30 minutes
4. Delete useless apps and pray to god that ur battery works like it used to
5. If you wont mind using any custom rom, then install echoe rom its based on stock rom nothings changed much except better battery and performance , i have used it and its awesome i totally recommend it

1. Go in auto start manager and ****ing close every useless social app(FB) they will suck it up
2. Choose power saver mode u like or use customized one
3. Do not use live wallpapers, well i use to change my wallpaper randomly every 30 minutes
4. Delete useless apps and pray to god that ur battery works like it used to
5. If you wont mind using any custom rom, then install echoe rom its based on stock rom nothings changed much except better battery and performance , i have used it and its awesome i totally recommend it

Thanks for those tips. I have all of that set up already. Custom power saver profile, all unnecessary apps removed or disabled, including auto start manager.
I have not rooted my device, only had it a month so I want to preserve warranty status.
I waited a couple of days to see if the battery would sort itself out, and it did.
Battery life has actually now improved slightly from what it was before the random drain happened.

[Battery Problem] Battery drains super fast and device overheats

Hey there,
First of all im using android 6.0 and i took of the case.
Last week my device suddenly began overheating and discharging aproximaly 1 precent every 2 minutes . Its even discharging while connected to the charger.
Pretty sure it has nothing to do with battery itself because i tried 4 different original batteries which all work perfectly fine with a different device.
I also tried to factory reset with no help..
I had a few "breaks" from this problem and sometimes it dosn't discharges quickly but when i start to use it, it starts to discharge fast again...
Is there something i can check before i send it away to the company to check it?
Thanks in advance,
Rony.
