Hello
I've been installing so much rom's in my atrix, but i always have this problem, the battery indicator only shows 70% when my battery actually is full (aprox 4200mV).
I've been reading a lot of methods to calibrate the battery but noone seems to working with me. I'm always stucked at 70% when i'm actually full. I know that this is not a big deal, but it would be great to know that correct value of charge in my phone
Do you know how to solve this?

My understanding is this is a "bug" in all non-blur based ROMs. The only solution I have found is this:

Basically, you have to reboot your phone after you fully charge it from this App. Hope this helps....
I'll give a try, thanks

Hello guys,
I have a problem with battery :
Every morning, after booting, my phone was powered off over all the night, I can see my battery decreasing by 10%!!!! And I sometimes notice after few minutes that it increases itself bit by bit...
I've already did a battery calibration, but not after flashing the new Siyah' 2.0 kernel.
This is very annoying, and makes me wondering if I should recalibrate or what...???
BTW, the question is : HOW ?
Some say you have first delete batterstats, power off, then full charge.
Others say you have to power off, full charge, manually delete batterstats.bin, or use Battery Calibration App.
What is the f*** best way to calibrate our battery ?
I'm really pissed off loosing 10% battery with my phone powered off every morning...
Regards.
Using Revolution 2.7.1 ROM with SiyahKernel v2.0
Was there really any need to create this thread in Q&A and then 30 mins later create the exact same thread in general?
If you read the FAQ on the SiyahKernel v2.0 thread it clearly states:
Q: do I need to recalibrate the battery?
A: You don't need to calibrate battery for SGS2. Thanks to Entropy512 to pointing out that our device uses MAX17042 which is specifically designed not to require calibration.
Therefore it is not a battery calibration error, you should get your battery checked or replaced as it may be faulty. Good luck!
Of course, no.
Sorry for duplicate that thread.

I've already read it.
But the fact is I am not the only one who gets issue with battery calibration, when flashin new kernel/ROM.
Shall we all replace our battery for a new one ? I don't think so at first sight.
In addition, many people notice calibration really works and make the battery more accurate than before... Common placebo or what ?
Hmmm...
It's definitely weird if powering off your device still drains as much as 10% overnight. I don't think any battery calibration can stop the phone from draining when off.
Have you tried reflashing a stock rom? From my experiences, the stock rom gave me the longest battery life when I first got my phone, but that may just be the fact the phone was new.
No, I've been stayed with Revolution ROM for a while.
At the beginning, never had this dropping issue. Seems to starting after flashing Revo 2.7.1 and Siyah' kernel, but not 100% sure.
It is very strange cause, I use it normally and battery is working fine : no decreasing on deep sleep.
Maybe this could help :
Just after full charging, use Battery Calibration App, and notice it didn't delete Batterystats.bin in data/system... I've always use it and never pay attention... (maybe error with SU permission ?)
Very strange, so this time I delete it manually.
Hope it'll calibrate my battery well this time.
Wait n see.
My first current conclusion :
The best way to calibrate your f*** battery is definitely to do it manually.
Just delete batterystats.bin in data/system, after full charging (with Rootexplorer or another app)
Then, use it until to 90%, and full charging.
That's all ATM.
Why ?
Because, I've just noticed that Battery Calibration App doesn't always delete this file. Ya, sometimes, It works, but sometimes It sucks. I don't know why, but seems to be related to some SU version and permissions' bugs...
Hope it could help some of you.
hi,I'm a noob and sorry for my bad English.
I flashed my mini pro to FXP052 and found the battery drain is about 2% drop an hour,which is acceptable to me.
However,I'd like to ask does anyone encounters the phone power off while battery life is around 10%?And when I plug in the charger,the percentage soars to 10% from 1% within one minute.
P.S. I have done battery calibration several times.
no solution yet for that kind of problem, seems that problem in battery.
Got it.
I flashed FXP105 and now it shuts down at about 5%,seems to get improved.
Anyway,thanks for your response.
I've read of this happening a few times - there's even a current thread on the SE forums about it. The solution that's usually offered - and appears to work for most cases - is to remove the battery and then put it back in after a couple of seconds. Sounds like a very simple solution and I've no way to check it (not having the problem) but worth a try - and if it works, credit goes to one of the SE forum mods.
As a matter of fact,I had tried that way but in vain.
I have two SE's batteries(EP500) and this problem occurs in both of them.
Nevertheless,thanks for the information,my friend.
I just got a response from the developer of the app, "Battery Monitor Widget Pro" in regards to a completely unrelated question. The dev said that in some Android devices, the kernels will have the battery size hardcoded into the kernel.
Does anyone know if this is true for our device and if so, how to change it without having to jump through a bunch of hacking an reprogramming hoops?
I ask because I bought the Hyperion 1800mAh extended battery for my phone and want to be sure that the phone is reading its size correctly. Currently, with the new battery installed, the battery level will sometimes randomly drop about 30% after a reboot (although, I have read this as being a common occurance for other people too) and when charging, the phone will stop charging and claim to be at 100%, but then will drop down to around 95% once unplugged. I have tried recalibrating the battery several times with no improvement, so after hearing about this "hardcoded into kernel" thing, I started thinking that this could be my problem.
For the record, I am on UCKH7 stock, with the exception of being rooted. (UCKK6 gave me phone call problems so I reverted back).
Another Q:
I should also ask if there is any way to force the system to properly read the battery level.
No - hardcoding the battery size only applies to fuel gauges of the "coulomb counter" type - these measure every bit of energy that goes in and out of the battery and track it, so they need to know how much energy the battery has at maximum.
These types of gauges are highly accurate when properly calibrated, but they drift over time and can become wildly inaccurate in many situations. Such fuel gauges can go utterly nuts if you swap batteries, unless the battery itself has memory in it.
Our fuel gauge is of a different type that uses the voltage history of the battery to provide an estimate of the charge - it is somewhat less accurate (could be as much as +/- 5% I'm guessing, except in corner cases such as a reboot at low charge state, which throws it off temporarily) but has the advantage of always converging on reality over time, so it never requires one to pay attention to calibration.
If your fuel gauge is really wacked out (such as a reboot at low charge, which confuses it with high load after a reset), the following will reset it again:
Code:
echo "1" > /sys/class/power_supply/fuelgauge/fg_reset_soc
Of course, this can make things worse if your battery is in any situation other than light load.
Thanks for the reply.
Will that code (used in a terminal on the the phone, I suppose? Correct me if I am wrong please) work the same way as deleting the batterystats.bin file?
Also, if i were to use that command you gave, what would I need to do? By this I mean, does the phone need to be charged to 100%, do I need to do it while still plugged into the charger as well, etc etc.
I don't want to go off and do something that could screw up my phone, but am definitely interested in knowing more about what that command can do for me.
I look forward to your reply

No, since this actually does something. Deleting batterystats.bin on our device does nothing.

Just do nothing, although ideally to prevent the fuel gauge from getting confused again, do it when the phone has been under very light load, and then don't use the phone much for a few minutes afterwards (turn the screen off).
None of that "charge to 100%" stuff is applicable to our phone due to the way the gauge works - it's only for devices that have coulomb counter fuel gauges (the ones that need the battery capacity hardcoded).
Thank you and don't worry because I wasn't really going to do that unless I REALLY had to. I just like to know this stuff.
After some some full charge/discharge cycles, my battery seems stable now. Battery life could be better though, but at least I get through the day while it is on standby.
Thanks for all the info
Is it the same for the captivate? I have 2 captivates, both on identical roms, flashed identical ways, but for some reason, the battery is awful on one.
Could it be possible the gauge is just way off? I've deleted batterystats.bin but does it even do anything on that phone?
I obviously cannot answer your whole question, but I can answer the one about the batterystats.bin.
The purpose for deleting the batterystats.bin file is to help Android to relearn the upper and lower limits of the battery (ie where 100% and 0% is). So, if you delete that file, then you need to let to phone charge to 100% and then let it drain until the phone turns itself automatically. This process needs to be repeating for several days.
The rest I cant answer since it is all new info to me
I wouldnt recommend that command that was given earlier because if it has potential to mess MY phone up, it will probably be the same for you too.

If they are running the EXACT same firmware, then the battery may simply be defective.
The Captivate has a fuel gauge similar to ours - MAX17040 instead of MAX17042. The 17040's datasheet is public, the 17042 (ours) is not, but from reading the kernel source and such, the 17042 in ours is almost identical - it adds a few features Samsung isn't using.

JESUS FREAKING CHRIST! DID YOU READ A SINGLE THING I SAID?
batterystats.bin has NO effect on the fuel gauge on our phone. PERIOD.
STOP BLINDLY APPLYING HTCISMS TO A SAMSUNG PHONE.
In fact, please refrain from commenting on this subject on a Samsung phone ever again until:
1) You have read and understand the Maxim MAX17040 IC datasheet
2) You have read and understand the kernel source for our fuel gauge driver in max17042-fuelgauge.c
While I appreciate your earlier help, I THOUGHT I WAS understanding it!
THERE IS ABSOLUTELY NO REASON TO BE SUCH A JERK TO PEOPLE JUST BECAUSE THEY DONT FULLY UNDERSTAND YOU!!!! IF NORMAL PEOPLE LIKE ME DO NOT UNDERSTAND WHAT YOU SAY, THEN IT IS YOOOUUUUR FAULT BECAUSE YOU ARE USING LANGUAGE THAT IS TOO GEEKY FOR US TO UNDERSTAND IN THE FIRST PLACE!!!!!
Just because you made a custom kernel and some other crap, doesn't make you king of the forums and give you the right to talk down on people!!!

Look, while I dont agree with the way that Entropy answered you, he didnt break any rules. He answered you and then had to re-answer you. If you didnt like his answer or found it jerkish, then move on. This post does not help the matter at all, in fact it could be viewed as a troll.
He didnt use "geeky language" at all, in fact those terms are used in the development forums quite often. If you dont understand those, then either search to look them up or Google them to get a better understanding. Its not his fault at all because he did not make up the names or the commands. Again, if you dont understand any of this, then you probably have no business tinkering with your phone.
Entropy has arguably one of the best kernels for our phone right now, not just some kernel... and his "other crap" is widely used and appreciated. If you dont like his work, then dont use it but DO NOT put down his work that he does for free and then offers his work for free for people to use.
Since this thread got too geeky, and the main question has been answered, Im going to close this thread to prevent any further bickering.
I am one of the many having the battery charging issue - won't charge past 85%... As I am using NottachTrix4G 1.3.1 (a Motorola-based ROM) with the standard Kernel I can't see what might be causing the trouble.
The only thing I can think which is not standard relating to this is that NottachTrix4G has the 1% battery mod.
So, the question is, does anyone know if it is possible to revert to completely stock Motorola battery drivers, and remove this modification? I would prefer to be stuck with 10% increments if that might be causing issues.
Many thanks
James
Unless I'm mistaken, the 1% battery is strictly a display modification. Nothing was changed in regards to how the battery itself is monitored and handled by the system. At least, that's my understanding based on my (admittedly minor) work in theme creation and modification. As such, reversing this wouldn't really do anything other than mask the actual problem. (Someone please correct me on this if I'm mistaken.)
surrealjam, search the forum. Same question asked many times. Solution is simple but not so permanent.
Charge your phone with charger to 4200mV, leave charger connected, turn phone off, remove battery (charger is still connected!), wait for ?, put battery back, you'll see about 5%, charge battery for about 1h, turn phone on, disconnect charger.
You may clear battery stats from CWM.
Thanks for the input MJPollard. Zeljko, I'm well aware of that temporary fix.
Unfortunately there isn't permanent solution. Actually I'm investigating one, but I'll see is it or not.
Oh look! THIS thread again!

Hi everyone who see's this. I have recently changed battery to a new one as my old one broke. Since then, my battery seems to go down fairly quick when im using it but uses hardly anything when on standby. When it goes down, I leave it and the percentage goes upwards abit, such as from 100% down to 40% then up to about 65%. This annoys me because I dont know what my real percentage is. Does anyone know why this happens and does anyone know any suggestions? Would like it if anyone could help Thanks

Thats what happens when you charge your phone . ROFL... Jokes aside it it prety simple.
Basicaly (Very Basic) the Batter level is monitored by checking voltage levels by some fancy hardware. now when you have a high current(power) draw for a a short burst the battery voltage will drop but recover once the phone goes back onto a lower power mode. some batteries recover fast. some recover slowly.
now most of this will get filtered but sometimes it is too much for the chips so they say it was lower than it really was.
my phone does this all the time. and the correct battery level is what ever it is saying at the time it is just that the battery has recovered from the high current draw. (so has more "capacity" left)
hope that wasn't too confusing...
Pvy.
Ha that made me laugh, I never thought thats what happens when it charges ;D
Thanks, it never used to really happen with my old battery but as long as its not fully abnormal, i wont delete battery stats or anything.
BTW nice to see you back, I havnt seen your posts in a while. I liked and used the TEAM rom, what happened with it? Are you working on new ROMS for new phones now so theres no room for X10? Thanks ;D
