I did calibrated my battery with the root method and the charge-discharge methods two times now, but still it charges from 0 to 100 in 40 minutes (which is not possible, it's not really 100%) the phone keeps charging according to accubattery and the battery tab in configuration
If I unplug right when it says 100% the batter drains hella fast (even if i dont use it)
The solution is keep the phone plugged until it says charged in rhe battery screen which takes an extra 40 minutes before reaching 100%
But how to fix this wrong information? Is driving me nuts
Probably the cable?
If I reboot the phone when it reaches 100% it drops to about 85%, and when it reaches 100% and reboot it again it drops but now to 90~ and so on for a few times
Any help would be appreciated! I'm using AOSIP btw, but this have happened in all roms
Heyyo, from what I was told for battery calibration the only proper way to do it is to run EUI ROM for about a week.
If you're inclined to try that to fix battery calibration? I'd recommend the versions by ChrisBalGreece. Debloated and already has good mods to make EUI ROM more enjoyable and less odd. :good:
After that? You can try a custom Oreo ROM again and battery should be properly calibrated.
Sometimes too with custom ROMs I've observed that the Quick Charge 3.0 isn't as accurate as it should be and can even stop charging if it thinks the battery temperature is too high... Unfortunately without updated kernel source code from LeEco it's something we cannot 100% solve so I'd recommend trying to charge with a 5V 2Amp charging block and see what happens as well.
ThE_MarD any eui 5.8 rom will work? i have flashed your 30s firmware of your lineageos thread will it work with that or i have to change firmware?
i have the original charger and cable
Well, I used to have that annoying problem, I made a research to find a solution, and something worked for me, Now my battery is perfectly calibrated. Well, I don't know if it would work for anyone else, but, you don't lose nothing trying right?
The first thing I did was install this: https://play.google.com/store/apps/details?id=flar2.exkernelmanager , and Configured the "saver mode" to low frequency of processor and activated it. Then I installed this https://play.google.com/store/apps/details?id=com.slash.batterychargelimit and activated the limit to 95% for high level and 90% to low level of battery charging, and after a couple of times charging and discharging my battery with that method now my battery magically calibrated itself, and now I can install any Oreo ROM with no problem, of course it is not necessary to use that saver mode all the time, but works really good. I have to say that now I am using "personalized resurrection remix" and it works fast as hell with the most complete tools for personalizing the phone (the best one for me), and it has an extreme good performance for gaming, of course not the best for battery, but there you can use and configure the saver profile of the app I mentioned, and you will have the best ROM available now. (Tryed a lot of them).
Thanks for reading. (Don't forget to install magisk for root, without that, nothing will happen)

I've got this problem with my tab (quick battery drainage). Symptoms would be your 100% charged tab would go down to 0% in unusual shorter time ( like 2-4 hours). You put it on charger and tab would be charged back to 100% again in substantial short time like 2-3 hours instead of 6-7 hours.
Well, after looking at this issue I think I have come up with solution.
At least, my tab looks like it's back on track... though, to say for sure I would need another couple days of testing.
The problem is not runaway wild application on a background but battery control circuit. This chip reports to OS much smaller battery capacity as it is for some reason. I will not go into details but here is what you need to try:
Flash stock kernel (may be custom kernel is not the reason for bad chip calibration and I'm 90% positive but just to be on safe side). You don't need to do factory wipe in OEM recovery for our purpose.
You also don't need to wipe batterystats.bin or use "Battery Calibration" apps from market (which does exactly the same wipe just in more end user friendly way). This wipe serves no other purpose then refreshing your usage statistics.
You also don't need to drain your battery all way down... nice, this way you don't have to wait for too long.
Well, here we go:
charge tab somewhere in between 80 and 100%.
edit: remove charger
shutdown tab (not put in hibernate/sleep) for 1 hour.
edit: turn tab on and run it for 30-40 min. or whatever it takes to drop charge to 40-50%.
shutdown tab again for 5 hours (overnight).
turn tab again and check... you should be fine now, charge it again 100% and use as usual.
That should do correct chip calibration.
PS: the reason why this chip calibration went bad at the first still remains open.
EDIT: just want to give a shortcut for those who does not feel like reading through the thread.
http://forum.xda-developers.com/showpost.php?p=16771651&postcount=41
Edit: here is calibration procedure which was modified down this thread ...
1. in CWM/recovery let it sit till battery in terminal will show less then 3700. The less you can get it the better. 3400 is probably absolute minimum.
2. shut down tab and let it sit for 1 hour.
3. plug it to charger and charge it for 5 hours.
4. disconnected charger and let it sit for 1 hour.
5. boot up your tab and test it, it your battery still not calibrated you can flash back your backup and repeat calibration procedure.
Edit: if you physically disconnect battery (you have to disassemble tablet) and keep it for couple min. that would trigger FG chip to start with default SOC curve.
Any follow up? Did this fix work for you since yesterday or anyone else?
yup, this is it...
This is how properly calibrate sg tab's batteries. There are some variations to the process but essentially battery will be calibrated in two measurements which stand apart by minimum 40% when battery is at rest on time intervals 1 and 5 hours.
No need to do factory reset, wipe batterystats, use battery calibrator apps from market or dance around with rain stick... all this will give same result as woodoo magic... though if by some reason battery calibration conditions are met then one may claim a miracle.
*sigh of relief* looks like this worked. More people that have this issue should now about this. Thank you for the fix.

Is this the same as the Sleep on Death (SOD) syndrome? that while charging it dies overnight and then you have to long press the power button and/or charge it to get it back?
Worked for me so far all good thanks
Sent from my GT-P7510 using XDA Premium App
Thanks will try this after flashing many custom roms I've been suffering from fast drainage which is not normal from when I had it on stock.

How long your tab usually works on one charge? if 8 and more hours - then no, I would think that there is a bug in Android charger control.

May I ask what do you mean by rest time intervals of 1 and 5 hours?
Does it mean that the calibration will only take place when the tab is off for 1 hour, then switch on and used till battery depleted by a further 40% minimum and the switch off for another 5 hour. Correct?
Also , is this 40% refer to value before or after calibration? I asked this because when I restart my tab the value changed (ex: 36% before restart to 53% after restart)

Yes that's correct.
Fuel gauge chip will take 1 measurement of open circuit voltage and internal resistance only when battery is at rest (no charge/discharge) for at least 40min. - so I say 1 hour just to be sure...
Consecutive measurements, from which gauge chip can derive capacity of the battery have to be at least 40% and 5 hours apart.
Technically speaking, that 40% difference can be in either directions. Say you have 40% as of now, leave it in rest for 1 hour, then charge it to 100% and leave it at rest for 5 hours and you will have same result.
Condition "at rest" means voltage change less then 4mV (or mkV) per sec. - I don't remember.
When tablet is in sleep some background processes may awake tablet briefly and reset the 1 hour counter - so to make it work for sure, simply do shutdown.

I tried this method...
1.Charged tab t0 80%, then shut down (removed charger) for 1 hour.
2.Turned on tab and played games for about 45min till battery was 49%.
3.Turned off tab and let sleep for 5 hours (charger still removed).
4.Turned tab back on and battery reads 79%, used for about 20min and battery reads 68%... Seems battery drain is still happening?
Right now i'm charging the tablet back upto 100% then perhaps try this method again... Did I do something wrong?

same problem im facing. This is why im wondering is the 40% value of before or after calibration. Because although it might drop 40% before calibration is done, the real drop value might be less then that. Which means to the chip it might just see a drop of example 20% of real drop and hence it didn't perform the calibration because conditions of 40% is nt met.
I did forget to flash back to the stock kernel (using pershoot's).
I just flashed to doc's slim 6.5 which has a modified stock kernel (couldnt find just the stock kernel and my internet is too slow to download the entire stock rom.). Going to try this method again but starting at 40%
1.Battery at 40%, shutdown tablet for 1 hour.
2.Charge tablet to 100% (while shutdown)
3.Leave tablet shutdown for 5 hours
4.Pray to droid gods, find my rain stick and begin dark resurrection ritual while watching true blood.
My only question now is... Should I turn the tablet back on after the 1 hour shutdown? Or should I leave it shutdown and just plug in charger till its 100% charged, then let it stay shutdown for 5 hours?
This is what worked for me:
1. Charged tab to 100% removed from charger.
2. Power down for 1 hour.
3. Power on (tab at 96%)
4. Drain to 46%
5. Power off for 5 hours
When I powered the tab back on after the 5 hours, i used it for a while and rebooted and the battery reading stayed the same which it wasn't doing before the calibration. It has been draining and charging at a normal pace since then and has remained the same after reboots and ROM flashes since the calibration.

I'm going to go ahead and try this method right now! But for me... sometimes my battery will not charge unless the unit is shutdown (ever since battery issues started.). I hope this time it will charge while its on.
Also the instructions say to flash the stock kernel before trying this method... Did you do this? And were you able to flash back to pershoot's without issue?
*Update:
It doesn't look like its charging, (system on). Should I just shutdown and charge it to 100%? Then continue with said method? Anyone know if this method will work while tablet is shutdown through the entire process?

My tab was charging while on, sometimes it wouldn't show it till after a reboot. I did mine from stock 3.1. (A backup I made before I took the TW OTA) I have not re-flashed pershoot's kernel and probably wont till the bug is worked out. I did however flash the deodexed stock TW and flashed a theme and have had no issues.
Edit: if its not chargin while on, i would charge it all the way while off then turn it on so it can read the battery then start the 1 hour power down.
Correction guys...
I was sure that our p7510 model was using TI bq20z75 fuel gauge chip but with new information looks like it's Maxim 17042 chip... It's embarrassing but I have to stay corrected. TI chip would calibrate itself in procedure outlined above as for Maxim - I don't know yet. I'm looking at it.
These are good and bad news. Good one - with this new fact, it's very possible that the reason of chip's SOC counter corruption is in software. Driver for Maxim is pretty messy and complex (because it's messy). In contrast driver for TI is simple and straight forward (because TI chip is smart). Software can be fixed but problem in hardware design not so easy.
Well, I will report back when I find something.
So, will FillTheVoid 's method work with my GT-p7510? :x

A lot of this is way over my head, but my battery calibration seems to be accurate, although I can't be absolutely sure because I have no stats from the previous calibration to compare it to. I do know for sure that after this process the bug of it draining then after reboot going back to what it should be is gone.
so i guess we need to flash back the stock ROM w/o TW for this procedure to work? I was trying the same steps with StarBurst + pershoot kernel it seem that it doesn't work. Anyone manage to calibrate with pershoot kernel?
Good fellow, again around here bothering me. I tell the 19 May last buy a Galaxy S2, came factory sealed, in fact I remove the seal, the question is that since last Sunday something very strange happens to me: charge the battery at 100% and start using the phone normally when it reaches between 30% and 40%, begins to fade as the lighting of the tactile buttons and screen, that when I have activated mobile data and the need as more cel battery consumption between the headed or cel energy loss and lose the signal goes out, if I disable mobile data if it holds until the battery to discharge, but connect with the phone off and make me inmediantamente load of 30% when it is assumed that the cel was shut down because was downloaded.
To tell a friend tell me that you step on something like a SE x10 and it was the battery with a voltage problem. Then you believe it is, that the battery is damaged and not the power to mobile or mobile to be problem?
I wonder I did, I did the following:
Calibrate the battery with CWM (I deleted the batery Stats)
I did 3 complete cycles of battery
With a multimeter measures the voltage of the battery and gave me when it comes to 3.80% by giving the prooblema and 4.10 with the battery fully charged.
To rule out problems with the loader, load it with the PC, the battery lasted a little more me, but I spend as already mentioned.
I flashed 5 times and install the ROM Andyx
If I connect to the socket and use it although it is very hard not pass this probleme when I use it only with the battery, when it comes to the percentage of battery I have before mentioned active data and give it a very intensive use (internet, games, benchmarking, etc.).
Since I bought I notice that my view is loaded very fast and just as quick to download, but until Sunday presents ehstos symptoms.
They think it's worth it to buy another battery or mobile internal problem?
Probe version of ICS LPJ European modem with LPS, the LPW and now I have the ROM ROM Andyx Extremev0 Apollo kernel and all feel the same, with percentage and holds more than others, but all happens to me .
Please help and many thanks in advance.
Good day fellow XDA members. I am currently running an unofficial Cyanogenmod ROM for my Huawei Ideos x3 u8510. So far, I love it! I have already calibrated my battery after flashing the ROM, by charging to 100%, using Battery Calibration from Play Store, letting it drain to 0% and charging it to full nonstop. My situation is the following, my battery still drains after I have calibrated it, (I did it yesterday), when I use the phone. If I don't use it, 1 or 2% drains aprox. every hour or hour and a half. After investigating here and other pages, some say that after calibrating your battery you have to let the ROM settle it after a few days, that way it's life gets better or "more accurate". Ok, I now need patience. My second situation is this, I want to know some of the BEST possible ways to save battery on Cyanogenmod, as battery lasted longer on my Stock ROM. Here are my descriptions:
-Use wireless networks when necessary,
-Brightness all the way down.
-Every basic thing I know.
Ok, those are the basics, but what are the best CPU settings to have the best battery life and at the same time have a fast phone? Here are my current settings:
-Governor: ONDEMAND
-Min CPU: 245 mhz
-Max CPU: 600 mhz
-Compache RAM usage: Disabled.
-Use JIT: Checked
-Enable surface dithering: Unchecked.
-Use 16 bit transparency: Checked
-Scrolling cache: Default enable
-Allow purging of assets: Unchecked
-Disable boot animation: Unchecked
-Lock home in memory: Unchecked
-Lock messaging app in memory: Unchecked.
My current kernel: 2-6-35.7-perf
[email protected]#1
So, can anybody suggest me the best settings to save battery life and have a good to great perfomance? Please answer, there have been 2 forums I already asked, but no one has answered.
Seriously? No one?

Thanks for your answer, but I forgot to mention something. My battery drains like 1 or 2% every 5 minutes when I use the phone. I wanted to know what SETTINGS or suggestions are best for battery life saving in CM 7.2.
By the way, I flashed a new ROM yesterday, it's very complete! The thing is, when I was charging my battery on the outlet, the indicator showed 89% of battery charged. After that, no more than 30 seconds passed and my phone was charged! Weird huh? So, I left my phone charging for 5 more minutes and then, the indicator showed 89% again with the charger connected! What I did was download Battery Calibration via Play Store, charged to 100%, eliminated batterystats.bin via this apk, and I think my indicator got "fixed".
My question is this, do I really need to recalibrate my battery or what I did was enough? I ask since I read battery calibration is a myth. Is this true? Or do I really need to calibrate it after flashing a new ROM?
Please answer!

cpu settings are subjective for every device i guess. i using vsel formula to calculate it. frequency/20 + 2. and do stability test to make sure the settings are stable.
may i know CM 7.2 from which build? last time i using cm 7.2 fuzz, i had to replace battd file for battery to indicate properly.
i had no idea about the myth because im not expert. batterystats.bin reset itself if you unplugged your device when it full charged.
my suggestion, use for a few cycle and see if any improvement.:good:

Actually, it's an unoffcial ROM I found, but it hasn't been the only one that makes my battery drain. Basically, it's been all custom ROMs I have tried out. I'll take your tip, thanks! :good:
The issue regarding charging the battery to keep the battery life as long as possible has always been debated for several years. There are many out there who either believe that it's now safe to charge however you want because of the modern technology and safety mechanism implemented on the phone. I still have this uneasiness though, particularly my battery health is about 85% after just one year of usage. I used to charge over night but I have dropped that habit about one or two months ago. Now that my phone is rooted, I wonder if there's a way to set the limit when we're charging the battery so in case I forget to plug it out or I want to leave it overnight but I still don't want it to charge to 100% I can do it.

Interesting
I just use a budi charger - I set it to charge for an hour as I go to bed. I wake in the morning and my phone's at 80-90% when I wake
Bingo
Edit
This would do the trick
There this Magisk module called IPC "Input Power Control" that basically automatically switches charging off when battery level reaches a certain disable threshold and back on as soon as it drowns to enable threshold.
Look it up here in Github if you want to know more
https://github.com/Magisk-Modules-Repo/IPControl
To all people who helped me, thanks a lot. Now I don't have to worry about charging my phone to 100% anymore if I forget. It works like a charm. 10/10 would customize something else again.
No matter how far battery technology has come, it is STILL a bad practice to keep a phone plugged in over night. The constant trickle charging deteriorates battery faster. Also never fully charge a battery and also never let a battery fully drain.
I charge my phone to 80%
And never let it go below 20%
If you need my sources for proof, let me know.
There are two scientific studies done specifically on this.

Hi everybody, if anyone is facing charging issues ,here is a few things I tried so you dont have to:
1. Flashed both force charge 2600mAh and 3300mAh magisk modules
2.Flashed another force charge module
3.Used D8G thermals and fast charge
4.Used many different kernels,
5.Re-calibrated the battery
but all in vain,the charging issue persisted,sometimes I had a ramped up charging,around 2700mAh,but one reboot and it would go to negative(yes acutally losing charge while plugging in).
So I noticed something, the battery temperature going above 40c caused the charging to decrease, if one could decrease the battery temperature and turn the screen off,the charging wont be rapid but still would charge(i mean it wont lose charge on plugging), but playing games while charging , I went upto 90% charge and started losing charge again(what a pain). So I tried changing thermal-engine.conf file located in vendor/etc folder to see if I could change the threshold of the temperatures, but still failed,
So I've actually reverted back to the stock ROM for now and I'm looking around the thermal threshold in stock ROM for now.
Hope I'll find something and would share it with you guys soon.
P.S If anyone has a solution please share
