im new to rooting, and i apologize if this is the wrong forum, but i believed it to be best.
my issue is that ever since installing the latest cyanogen mod, my battery is terrible, after about an hour i am down to 65-70 percent battery with minimal usage (no calls or programs, perhaps a text or 5)
i tried using the trouble shooting on the wiki which states
Code:
Battery recalibration
If you're experiencing higher than normal battery drain, try the following:
1. Charge the phone to full battery; power off and let it keep charging until the light is green.
2. Boot to recovery mode and go to console (or adb shell) and type:
mount -a
rm /data/system/batterystats.bin
1. Reboot the phone and use it normally, but don't charge until it shuts off.
2. Recharge the phone completely and then use as you normally would.
but when i tried the mount -a command i get various errors pertaining to "not found" i still typed in the rm command but i got no notification that it worked.
any ideas? im loving the mod, and the root community as a whole and i would hate to go back to the original rom
also another oddity i noticed... my battery will drain down to 20 or so percent, and ill plug in the charger for 10min and then itll say 97 percent? (not exact just round abouts of percentage) whats going on?
also ill reboot my phone or start it back up after it shut down to low power and itll be at 50% or way higher then it said it was when it shut down/rebooted
I dont believe it's a problem with the rom itself, it might just be the battery. I had that problem, and solved it simply by replacing my battery.
Did you overcharge your battery? If so, that's probably why your battery is unable hold a charge, or is giving off false percentages. (one way of knowing if you did is if the battery is bulging out)
there does seem to be a miniscule bulge on the battery, as i often left it plugged in even when it was at a 100percent. even so i did not have the severity of the problems i am having before i switched over to cyanogen
Same problem
My G1 has been shutting off at 70% battery, too. I tried to do the charge, mount -a, rm /data/system/batterystats.bin bit, and while I could mount -a, when I put in the rm command, the console returns that there's no such file or directory. My battery also has the tiniest bulge; is the next step to just get a new battery? I was not having this problem before Cyanogen Mod, either.

I rooted my phone for the first time and am using CM5.0.7. My battery is acting weird. Tried using the console and typing those commands above, but I get the error message as well. Does someone know the answer?
Thanks.
To all the posters that are having problems getting access to the file... You might want to try switching your recovery to Amon_RA's latest recovery. He has a menu option which removes the battery configuration file for you. I believe the option is under the wipe menu.
Additionally, make sure you follow the steps for recalibrating the battery outlined in the troubleshooting section of cyanogenmod's wiki because just deleting the batterystat file will not help with the battery drain unless you follow the steps.
in addition to all of this, the battery life issues on 5.0.7 is a known bug that cyanogen publicized on twitter through his own testing. it's currently being looked into. so far, wiping battery stats has had no measurable effect beyond what is percieved to be slightly longer life by the user.
my suggestion: stick it out until the fix comes, which will be prior to a "stable" CM5 release.

Good advice also. That is what I will be doing. I wanted to stick with this ROM so I tried the recalibration technique but I do confirm that it is having little effect.
yeah, there are people claiming that it's having miraculous effect, and then in the next sentence saying "oh, but i'm also not running any apps, have wifi, bluetooth, data and the screen turned off and it's been plugged in for half the time". you cant rely on results like that. if cyanogen says himself that theres a battery problem, i'd tend to take that as gospel. the man kinda knows what hes talking about on a massive scale.
try this
this was an issue with an old cyanogenmod. 3.8.1
I posted a workaround in the 5.0.7 thread. this worked for me, but YMMV.
add this to your userinit.sh file now located int /sd-ext/
Code:
echo 2000000 > /sys/devices/system/cpu/cpu0/cpufreq/ondemand/sampling_rate
or run command in the terminal (not recovery's console)
check it with
Code:
cat /sys/devices/system/cpu/cpu0/cpufreq/ondemand/sampling_rate
before and after if you run it in terminal.
alternatively, set this value in setCPU. under advanced.
my values:
Code:
sampling rate : 2000000
up threshold: 60
ignore nice load: 0
power save bias: 200
this gives me about 10%-15% less battery life than the last build. which is better than I was getting friday.

I beg to differ, I'm having the same issues on the Evo 4G and have tried three different batteries. All batteries drain rather quickly and take FOOOOOREEEEEVVVVVEEEERRRRRRRRRRRRRRRRR to charge. Plugged in over night for over six hours only reaching 63% battery capacity?! Absurd! Does not happen with any of the Stock ROMs.
i have the same problem with a LG GT540f ... i installed cyanogenmod 7 and the battery life is extremly unestable... 1 hour and my cel gets OFF ....
no solutions yet?

dont know if you guys experienced this or not, it seems like i cant get my phone to be fully charged after the 1.5 firmware update, it takes like 10 hours to get it fully charged. So i thought it was my phone, but after i get the replacement from t-mobile, its the same thing, so i thought its the battery, but after i replaced the battery which i got from HTC, it turns out to be the same....what do u guys think what happening to my phone ?
for example, if i charge my phone for 2 or 3 hours, and it says its 60% charged...then i reboot my phone, the battery bar becomes full, and i check the battery info, its 100% or 99%.....so you guys think it's the software issue ? maybe my phone is already fullly charged, but it just cant recognize it ? but this cant happen to 2 different phones with different batteries right ?
This happens to my phone even i flash it to the cyan 4.0.4
CyanogenMod-4.0.4
HardSPL
2.22.19.261
Please Help !!!!
weird, have u tried to UN-root?
ya...tried...was back to normal once when it was at 1.0 firmware, but then after i root or updated to 1.5 firmware, it happens again...i dont even know why this is happening
Anything running in the background sucking up battery power? Bluetooth enabled? Music/Video player "stopped"?
There is a file you can delete to make the phone forget its battery charge settings and start over. I searched but with the old Cy threads gone I can't find it. Try searching the forum a few different ways. Maybe it is also in a different rom thread. If I come across the file name I will post it here.
if i delete the file, would it indicate how much battery is left ? or how much battery has been charged ?
i think the directions on what file that needs be deleted are in the experimental thread, i remember reading about it as well. basically, what you are doing is deleting the old battery readings and the files that tell the phone how much juice the battery has left, and when you reboot after deleting them, it causes the phone to create new ones.

Try deleting batterystats.bin in /data/system if you upgraded without flashing. This will recalibrate your battery...

they don't want it to turn into another "I hate google" thread. i am pretty much sure that is the reason they locked it.
so if i delete batterystats.bin , the battery indicator would back to normal ?not just going up by only 1% for every 10 minutes ?

what command ? im not a tech savvy guy...so i will make sure all things are ok before doing anything to the phone.
i put the command up in the first page of this hread ,and it was still there when i looked a minute ago.
so after i deleted the file, and i go to the recover console and type the commands and thats it right ?
i tried....didnt work....
i rebooted to recovery mode, then select console..input the commands....reboot the phone...problem still not solved....hmmm
If I remember correctly wasn't the procedure for resetting the battery to completely drain the battery till the phone shuts off on it's own, then charge the battery while the power is off till charging light turns green, then when you boot your phone use the terminal or adb to remove batterystats.bin

Yes those are the proper instructions. Don't do this very often though, its not good for Li-ion batteries
What an interesting problem. I have never run across this problem before.
Guys,I own a T Mobile G1 Android 1.6 Phone and recently I’m facing some problems. The problem that appeared recently is with the battery drain. before some days ago the battery of my G1 lasted up to 4-5 days, without using Wireless, GPS, and Bluetooth. If I used the mentioned services normally the battery lasted up to two days. But recently the battery is draining too fast. Within 4 hours the battery goes down less then 15% even I do not use any mentioned services. I keep my phone on standby, without talking a single minute with the phone, not using any service etc, and again it goes down very quick. I took some measures according to HTC instructions how to save the battery but again it does not function. I uninstalled all applications and reset the phone to factory setting by again same thing. Then I searched on the Google some instructions, I tried also that one’s but again it does not function. I always used HTC charger that came with the phone but again same problem. What is the strangest thing that after some days the battery gets back and works perfectly for two weeks, which means I use the phone normally without charging 4-5 days. As I operate very well with the smartphones, Pocket PC’s etc I start analyzing G1 and monitoring very closely why the battery goes down, I monitored for a long time the query under the :About Phone-Battery use- and I see there that Andorid OS is using the battery from 76% up to 85%. Now it came to my mind that something is keeping engaged or it keeps running the Andorid OS always on. Then I suspected that thre my be any virus on my phone, but I installed form Market Flexilis/lookout antivirus application, but there was no virus and again the battery goes very quickly down. As I said after sometime the system returns to normal and the battery lasts for 4-5 days, and when I check the information under Phone,Battery use, I see that the Andorid OS is spending only 6% of the battery. Comparing with the previous description it is a huge difference. According to my opinion there is a small problem with any file which keeps always running to much the Andorid OS. Can you please give me any instruction why Andorid OS is spending that much the battery? Or give me any instruction how to prevent this operation that keeps Android OS to much engaged? or is there any programming mistake?, is there any need for update?, do I need to root my phone as it is not rooted? The reason why I’m thinking that there is a technical problem is because sometimes the system gets back to normal and sometimes it goes out of normal running. I appreciate a lot if you could help me to resolve the mentioned problem.
I've noticed the same thing on my G1 sometimes there is fast battery drain and it seems associated with Android OS. The percentage is over 70%. I also notice it be associated with the display as well. Could be that there is some process that won't stop running and is using Android OS or it could be that on other occasions the display is not going into sleep mode properly. I wish I knew how to fix these problems but I don't. I just observe them.
The battery issue, is an up and down problem for me. Sometime I can go through it in one day or less, other days it will last me for 2 plus days.
It also could be that the battery need replacing. Who's know.
I just bought a 2nd hand G1 - works just fine. I rooted and installed CM6.1.
My battery drains within 1-2 hours. I've tried various methods of resetting stats, with no luck. How frustrating! I wonder if it's a battery hardware problem or software?
battery
I also faced bad battery life on various roms. Since I'm using COS-DS (android 2.3.3) http://forum.xda-developers.com/showthread.php?t=950765 and the Biffmod kernel http://forum.xda-developers.com/showthread.php?t=950765 the phone runs more than 24h when texting and calling. Of course you should apply the 14MB RAM hack in comination with this kernel http://forum.xda-developers.com/showthread.php?t=831139. On standby (everything off, except data and 3g) my G1 runs >48h, before it needs to be plugged in.

Sounds like the basic description of the USB Charging Bug.
The bug triggers if the G1 is using a kernel starting 2.6.35 and onward tree, and charged using the USB instead of AC wall charger.
A couple of option to avoid the super discharge after that (you can use either);
1. Reboot after you unplug the USB charger.
2. Change kernel to one from 2.6.34 tree
You can also visit the Dev sub-forum, there's a thread there discussing the debugging process.
It is so unpredictable for me...I have just got into the habit of a reboot after unplugging USB.
Battery drain on the G1
I have the same problem. Even on standby it drops to less than half of its battery life. Sometimes its worse. today i noticed that the battery percentage was at 84. Next thing I know the phone reboots itself and it displays that it has 1% battery, battery icon empty all in red and LED flashing in red. Then I turn it off connect it to the charger, after a couple of seconds I turn it back on and says its 90 something percent. Could be a virus or just a battery bug,that's my guess. I scanned the phone with Lookout Security and there was no Virus,malware or spyware found.
I want to try different kernels for this battery issue but want to make sure I am installing the right one.
I have CM6.1 with 2.22.23.02 radio and DangerSPL installed. Can I just load any of the kernels built for EBI0?
Specifically, can I flash the kernel in the 1st post here? http://forum.xda-developers.com/showthread.php?t=1010932
Thanks.
Having seen so many posts on calibration of battery, i have decided to make this thread so to make it easier and useful for you guys. This thread can also be used to share your experiences with calibration and usage of milestone's battery.
Note: This is done using a the motorola milestone 1. So if you're using any other phone, pls ask abt them in this thread b4 you do anything!!!!
Intro:
The calibration of the battery is needed when you want to switch/install roms. This will make sure that the battery is really fully charged, thus preventing the battery life from dropping too drastically in a matter of hours.
I know there are some other methods to help calibrate your battery, but this is the only one I am sure of the steps. Please inform me of the other methods so to share with everybody.
Steps:
1. Before flashing a new rom, use root explorer (with read/write set) to delete the file "batterystats.bin" stored in /data/system/.
2. Charge your phone with it being turned off.
3. After it is fully charged(100%), take out its battery without plugging off the power supply.
4. Wait for a few moments, and a ? sign will appear.
5. Put your battery back in. You should see that the battery percentage increases quickly to 60%. If it increases to 100% with seconds, please skip to step 6.
6. If it stops increasing at 60%, let the phone continue to charge until 100%(takes quite a while)
7. Once it reaches 100%, let it charge for a further 15-20 minutes.
8. Once that's done, you can boot to OpenRecovery and flash your rom!!!
Alternative way of calibration(thanks a lot zeppelinrox!!!):
http://forum.xda-developers.com/showpost.php?p=11803458&postcount=10
This method allows you to calibrate the battery and use ur phone at the same time!!!
I hope this helps you people, because it really helped me!!!!
Note: i m not responsible for anything bad that happens to ur phone. Perform the calibration at ur own risk!!!(though it should be perfectly fine, unless u do something wrong or extra)
Btw, i am just writing things that i assume to be correct, so if anything needs to be edited/added, pls inform me through this thread or sending me a pm.
Credits to everyone (especially pcphobic for his post in http://forum.xda-developers.com/showpost.php?p=11604143&postcount=740) who have written all these in your posts that made it possible for me to gather and get all this info!!!!!!
You should give credits to whom you copied this from.
oh yea i almost forgot.Thx fellow citizen!!!!
And it's good to remove/wipe the battery status data with the charger plug-in as the last step.
thx bnwg, but i don't get you. Mind if you make yourself clearer? Thx!!!!

Calibrating Without Downtime!
Edit: If this doesn't work on your device, try the Die-Hard Battery Calibrator Script to ensure a proper charge
This is proven to work with Motorola Milestone so I would imagine the Droid as well.
It works with the Milestone 2 but you may need to get the phone booted up manually (step 7) instead of the easy reboot in step 6.
If you have a different phone and this works, please let us know!
You probably won't believe that this will work but try it anyway.
The big benefit of doing it this way:
It's great if you don't plan on changing roms and just want to calibrate your battery without downtime so that you can just use your phone as you normally would.
Note: Be sure that the phone isn't running hot (feel the back)
1. While in Android, charge up to 100% and leave the phone plugged in.
2. Delete /data/system/batterystats.bin
3. Remove back cover
4. Press Power and choose to reboot normally.
5. When the screen goes black and the lights go out, pull out the battery before you get the M logo. It will probably still work after the M logo shows up but that's how I do it.
6. Surprise: The phone will boot up without the battery! - Mine does - every time
Note: Batterystats.bin is recreated when you see the M logo - even though the battery isn't in the phone.
Go to Step 8 if the phone booted up as described.
7. If it doesn't boot up and you see the battery with the ?
..........a) Put the battery back in (you will see 60%),
..........b) Power off the phone (press power until LED light goes out)
..........c) Power on the phone (press power until you see the M logo)
..........d) Remove battery... and watch bootanimation...
8. a) After the surprise of seeing the boot animation without a battery, you will then see the lock screen along with a "No SIM card error" and no signal.
...... Put the battery back in - the SIM card error will disappear, you will get a signal, it will show 60% full and the icon will show the battery charging.
...... Go to Step 9 if this works as planned. If it doesn't, reboot (again without the battery) and use step 8b instead of step 8a.
... b) Put the battery back in during the bootanimation, but after the haptic feedback/vibration (and the buttons along the bottom light up).
....... On a normal reboot, you can actually slide and unlock the phone when you get the vibration during the boot animation. You knew that, right?
9. Use your phone normally while you calibrate the battery
10. Let it fill it up to 100% + 15 minutes or so. When it is truly finished charging, the battery should be cool.
11. If the phone is running hot, weird things can happen. For example, you may get no signal when you put the battery back in or the battery doesn't begin charging (the status bar battery icon doesn't change). Just let the phone cool off and it should work next time.
100% full is approximately 4200mV
As you can see in the cap below, it's showing only 60% at 4241mV (This was after booting up without the battery and putting the battery in)
A few minutes later, still plugged in, it showed 100% at 4225mV and then it went up to 4230mV.
Finally, I then unplugged the phone and I got a reading of 4196mV
Notes:
Now, when I charge it up, it will go up to 4230mV everytime. I leave it plugged in an extra few minutes after that.
I highly recommend Battery Monitor Widget
Batterystats.bin gets recreated if you unplug your phone and plug it in again. So don't do that. Let it get recreated on the M logo (Step 6).
Thanks to pcphobic for a couple of important tips and to pcphobic and sileshn both for confirming that my phone isn't possessed!

Recently I follow Azhad's way to wipe the battery.
When I delete the file (ie. cc_data) under that folder and go back in it, the file will be regenerated. And the batterystats.bin is updated according to the timestamp of the newly generated cc-data file. I don't know if this is the same as the step 6 from zeppelinrox's method.

the myth about the batterysoftware needs some real facts. payce from german forum did some measuring with real astonishing results.
I have seen that article before.. thanks to you of course
I'll quote the conclusion of the first post:
That is, the stone over-estimated the voltage at the battery is full by ~ 60 mV and underestimated the power of up to 100 mV with an empty battery. The intent is well-battery protection (which is good too). It is pretended that 3.0 and 4.2 volts to discharge until it is loaded. In reality, there are more 3.1 volts and 4.15 volts (which by the way of battery manufacturers also better unanimous opinion!).
Click to expand...
Click to collapse
So the reading I get via Battery Monitor Widget aren't that far off and perhaps exactly where they're supposed to be.
After fully charging (showing 4230mV while plugged in) and then uplugging the phone, it will ideally show between 4150mV and 4200mV vs the 4.15 volts (ie. 4150mV) quoted above.
My phone will power itself off between 3150mV and 3200mV vs the 3.1 volts (3100mV) quoted above. Actually, I just checked BMW's log and today it powered itself off at 3162mV after 19.5 hrs.
I found it interesting that you use less power while downloading overclocked versus downloading at stock speed lol.

Of course it would calibrate either way.
The difference is that I found a way to do it more conveniently.
You can do it anytime, use your phone normally and actually monitor the voltage as well.

After updating to 2.3.3 using COS-DS, my phone seemed to work fine. I initially had a battery drain with nothing taking up large battery usage, so I reset the battery stats and all was well.
However, after unplugging my phone from charging all night (100% upon unplug), I checked my phone two hours later and saw that my charge was down to 22%. Upon checking Battery Usage, I found that Android OS is using 76%! The only thing I've done today was answer a couple SMS messages. I don't have Sync, GPS, or Wifi on, but I do have Mobiledata and 3G+2G on, as well as Background Data. The only widget I have is Google Voice, which I've removed to no avail. I've tried rebooting (twice), but it stays the same. I've turned off data, gone to 2G-only, and turned off background data, and it still continues. In Spare Parts, under Battery history it says that the only thing using up the battery is Suspend in CPU, and Battery Status says that the battery's health is good. Something really strange is that after the initial power-off upon the discovery of this issue, I immediately plugged it into the charger. After about 3 minutes I turned it back on, and found that it's already charged back up to 86%. WHAT.
Also, I haven't plugged it into the computer once in the last few days, so it's not USB-bug related. Any ideas on what's going on here?
EDIT: Ok, it's been a couple hours since this began, but just now I checked the phone (it was on the charger) and suddenly EVERYTHING is gone from the Battery Usage page, save for Display and Android OS, and Android OS is back down to 5% now. Really bloody weird, but the issue seems to have resolved itself.
I've had similar issues. When my battery runs flat, dead. I plug it up and switched it on, and it shown "Charging (32%)". I get different but similar results with different ROMs. It could simply mean the battery is wasted couldn't it?
Have you gone into the Recovery mode and wipe the Battery Status? I was having similiar issue (but not a fast drain), I did maybe about 5 wiped and reboot the phone. My problem seem to go away.
I went from 1 day or less from 100% to having to recharge, to 2 and 1/2 days then charge.
The issue came back later that night, and has been happening ever since.
I've done the bump charge + stats wipe, where I let it charge to 100%, shutdown until green LED, wipe stats, restart, let drain to 0, restart and use. I've tried this about 3 or 4 times, and the issue persists. I've removed my 2 widgets (two sound effects widgets), and it persists.
Also, I've downloaded OS Monitor, and it shows the CPU to be resting at its min, 246.
I'm hoping it's just the battery at this point, and have already ordered another one. I'll let you guys know if that fixes it.
In that case it might be your battery that need to be replace. How old is the battery?
I really have no idea. I bought this G1 used on eBay 9 months ago.
2 things to note:
1. It actually stopped booting last night even while on the charger: I restarted, and it kept getting stuck on the splash image. So I superwiped, reflashed, and the drain is still there even with no user-installed apps.
2. About a month ago, (when I was back on a stable Froyo, which I had been on since I got the phone 9 months ago) it started to randomly shut off. It seemed like if it got just a little too hot (battery got to maybe 30 C, never was able to check what the temp was when this happened), it would shut down and wouldn't get past the boot screen without a reset. I had to either charge it or wait an hour for it to successfully boot again.
In retrospect, this is sounding more and more like the battery. The only thing that's strange is that Android OS takes up such high percentage. Oh well, hopefully the new battery gets here today or tomorrow, hopefully that fixes everything.
Since you have brought the G1 9 months ago, more than likely it's had been over two year or more (about the same age as mine more or less). I doubt that the seller would be giving you a brand new battery.
I noticed the reboot on mine G1 too. Ever so often, my G1 will reboot on me. But I do not have the problem getting stuck at the splash or boot screen. But then I am using the SuperAosp ROM not Froyo.
Let me know how the new battery will work out, I might have to end up getting it myself. Eventhough my battery life got better after I did the wipe battery status, sometime it still drain depending on the day I guess.
I noticed the same result with COSDS.
I moved to Ginger Yoshi with much better results.
Better, but not as good as stock, obviously.
COSDS turned into a real hog on me by the time the second or third reboot happened.
Heeter
I'll stay with SuperAosp, I take the performance over the battery life any day. My battery status an't that bad. Once in the while I used it up in a day or less, other I can stick around for a few days.
The rebooting part was not too bad on my end. Just once in a while. Nothing I can't handle.
@ psychosonic - You might want to try that if you want, Gingerbread Yoshi was one of my first choice before I found what I had.
Alright, got my battery. After calibrating it for one day, then using it today post-calibration, it's functioning phenomenally. After using wifi + internet for a period of time, and sms throughout the day, it's still at 70% 6 hours after charge. Essentially, the only thing that drains the battery is heavy internet use, which seems to make it go down 1% per 2 or 3 minutes.
Internet usage seem to take a lot out of the battery for sure. I know mine take a lot more than 1% every 2 or 3 mins when I use my internet.
Let see how will the new battery pan out. See if it will last you 2 or more days. Keep using it as such, and see where it goes.
Android OS Battery bug
Hi!
1. Install SystemPanelLite Task Manager from the market.
2. Run SystemPanel and open settings and check the "System processes" option. Close settings.
3. Scroll down in the process list until you find the process "android.process.media". If you have a CPU usage of more then 10-30s and the process usage gauge to the left moves up and down you probably have the Android OS battery bug.
At this point you can try the following;
- Shut down your phone. (Not just turn it of. The complete shut-down-power-off-thingy)
- Remove your external SD card.
- Start up your phone again.
- When the scan media is complete, do step 3 above again. If you don't see the problem at step 3 your SD card has a corrupt filesystem. And needs to be reformated. Follow these steps;
- Backup your data first!!!
- Settings -> SD card & phone storage
- Unmount SD card
- Format SD card
- Restore files from your backup.
If the problem persists your internal SD card might have a corrupt filesystem and needs to be reformated. Follow these steps;
- Backup your data first!!!
- Settings -> SD card & phone storage
- Format internal storage
- Restore files from your backup.
More details; What happens when you have a corrupt filesystem is that android.process.media tries to read a file but fails over and over again. The filesystem might not look corrupt to you. And you can read and write files on the SD card without problems. But at some point the android.process.media failes to read the files and loops like crazy, draining your battery.
I had a corrupt filesystem (FAT32) on my external SD card. I also had Android OS battery usage of 60-70% and a fast draining battery. I hope this can help others.

cos dds sucks battery.... yoshi"s awesome..!! fr battery!!
if you applied a theme in theme chooser it could have affected it

Is that battery original?
Same thing happened to me on another device with cheap Chinese batteries that were supposed to be original.
First battery was original...not good probably too old to hold on
The second one i believe was some chinese crap for 10 euros(service said it was original)
The second one i paid like 35 euros and it's a li-po made by powery...heard a lot of good words about that battery maker
I've had the Tab S since launch, and I'm on my 3rd battery for this problem, and it looks like I'll need a fourth at this point. Sadly, the batteries do this. I've gotten this problem with official and non-official batteries. You can avoid the issue by not leaving the phone plugged in charging at 100% for extended periods (like while you sleep).
You can mitigate the issue doing this - let the battery run out so the OS shuts down from reporting 1% or 0% battery, boot it up in recovery, and let the battery drain (best way to do this is with TWRP, max screen brightness, always on screen and go into Advanced, Terminal and run "yes > /dev/null & yes > /dev/null & yes > /dev/null & yes > /dev/null", this will max 4 CPU cores and drain the battery) until the phone turns off and will not turn back on again. Then, charge it back to 100% in one go (you can boot into the OS for this, just don't disconnect the cable until you're at 100%). Do this two or three times.
This will NOT fix the problem. You will have to do this again at some point (week to a month) until you get a new battery. This will just stop the freezes/screen flicker/incorrect battery value.
This is probably the only bad thing about the Tab S in my opinion.

We have probably one of the best tablets ever made by Samsung, and yet, we face this very irritating and inconvenient battery issue. I will certainly try your excellent detailed instructions when I change my battery, soon. Thanks!
Just instruct your tablet (on settings) to turn off wifi when screen is off.
Still on the original battery and I'm doing fine.
