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
This might just be the ramblings of a mad man, but I have been thinking lots lately about battery calibration on the sgs2.
Normally on most android phones the power off charge is completely independent from the rom so that if you charge when powered off you know it is really a full charge, not controlled by pre-logged battery stats, you can then wipe the stats and get a better idea of what "full" is when you are powered on.
On the SGS2 the charge when powered off is still controlled by the rom (see the app "no moar powah" for an example of this), therefore it may still be under the control of the same battery stats so may not indeed charge any more than what the rom thinks is full when you are powered on.
Wow, thanks for your explanation...
But, it makes me perplexed. If you're alright, you mean that battery calibration doesn't work on S2 ?!
So, in this case, how to solve my problem ?

the best thing you can try is to run the battery flat, charge while off, wipe battery stats anyway and hope for the best.
Will try it again ....
Maybe should I flash another rom after full wipe, or stick to a stock one.
I can't imagine that my battery is defected yet !
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.
Maybe, it'll calibrate my battery well this time.
Wait n see.

Weirdly, I noticed that yesterday! I don't think it works on all roms, I'm definitely going to do it manually from now on.
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.

Is that the same as doing it through Clockworkmod advanced/wipe battery stats?
It is normally the same thing, I prefer IMO to do it manually.

Well you can just charge your phone to 100% and then delete the batterystats.bin file via Root Explorer or boot into cwm and go to advance-delete batterystats.
That helps you and your system to get a more accurate reading.
Other option is to "bump" charge your phone, let it charge till 100%, wait one hour (while charging). Unplug phone and turn off, plugin in charger again and charge for another hour. Turn on phone and delete batterystats.bin. Bump charging isnt healthy for your battery tho and just gives a temporary effect of "better" battery life.

well, i know its funny to say it here but my phone is not rooted and im not a programmer, i just came here because i know that you guys know those stuff.
so, any (official?) way of doing this without messing with the system files?

As the battery stats are a system file then no as you dont want to mess with system files you say .
Battery stats if left alone will reset within a few weeks of use anyway .
The majority are not programmers we just follow the instructions .

i dont see a reason why would i want to delete this file, as my phone is just 1 week old and i thought there are some calibrations need to be done when you get the phone..
i assume what you guys are suggestions is some periodic treatment to do to the phone after few weeks/months i already have it?
if so, again, as my phone is new - is there anything i should do to the battery?

No charge it use it dont let it fully discharge .
battery recalibration is only of possible use after flashing a new rom.

i have another small question:
when going to "battery useage" i can see that my phone is "awake" at all times, even when the screen turned off and not using it.
BUT the wifi was on the whole time, would that be the reason?
any possible way to determine whats preventing the phone from sleeping?
thanks
It depends on what apps you use. For instance IM applications keep the phone alive, while the screen sleeps.

WiFi could be on always but not Awake, so some apps/process must be going on in background, to find what it is,

I am relicabrating the battery after flashing a new rom too.
after i recharge the battery overnight i boot into cwm recovery and delete the battery stats.
but what about if you have 2 different batteries (original samsung) and use them alternate after one battery is fully discharged.
do i need to obbey anything different ?
Hope anybody can enlighten that issue.

Imo, you will get false readings everytime you will change the battery.
there's no solution for synchronising it or i.e. calibrating the battery1 and then changing somtime to battery2, then you'll get wrong information from the system about the charge of the battery, because it's calibrated to battery1, okay but if you then change back to battery1, the system info about the charge of battery1 should be fine... hope you understand what i want to explain

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.

Here is something I just noticed I sometimes wipe my battery stats once I get a full charge on a new rom. I always wipe and flash using fastboot boot recovery.img.
Roms always run fine smooth no issues. But for some reason if I go and wipe my battery stats after a full charge my gauge will lock up and the battery chart doesn't work anymore...
Even a reflash and wipe doesn't help. What would cause this issue?
Im on hboot 1.5
I know back when I would just flash the boot.img then the rom.. I never had issues wipeing my battery stats....
So anyone else have this issue?
I know folks say you don't need to but some times you do need to if you flash a rom and for some reason your battery gauge sticks at 99% green light... Will never hit 100%..
it eventually will hit 100%... you have to charge it while the phone is off just once and it will green light while off... then boot up and charge again and it will hit 100...
also, what exactly do you mean by the battery chart??
it shouldn't have an issue because your voltage/charge is monitored by the kernel... kind of an odd little anomaly to be honest.

here's the thing, the reason why you are not seeing anything in your battery usage is because that's exactly what the batterystats.bin file is - it is a data dump of statistics... what has been using your battery, for how long, all kinds of mathematical outputs of screen on usage, awake time, apps, so on and so forth... converts all of that into a percentage and that's what you are seeing in your settings/battery usage.
so, accordingly, when you delete batterystats.bin, all of those statistics are gone and you have nothing to display. after a charge cycle or so, you will see that information displayed again.
again, batterystats.bin is simply the statistics of what has been using the battery. has nothing to do with the phone's actually ability to display the correct percentage, get a full charge, etc... that is ALL the Linux kernel which is your power management for the device.
wiping batterystats is truly unnecessary. does nothing for your battery life, and flashing a ROM then wiping battery stats is useless too because when you flash a ROM you wipe data... and the batterystats.bin is found in /data/system... so effectively you are wiping battery stats every time you flash a ROM.
but to go back to the OP... not sure why your percentage is not being displayed correctly... sounds like a ROM issue.

Ya I pulled the battery let the phone discharge and put it back in finally got everything working again ... I was on nightlys a few days ago and flashed one last night that was when I had some funky issues with the battery gauge after doing a wipe.
I only do a wipe if the gauge gets dicked up...
Anyways thanks man... Hopefully I fixed this sucker...
yeah, definitely was a ROM issue...
hope it's worked out and no problem man. hope all that rambling made sense, haha.

hi
is it required to battery caliberate after flashing new rom?
and when ever i reboot my system either battery jumps from 10% to 30 or more
or becomes less than 10%..
if i should then which app should i use?
any guidnace
plz
TY
No such thing. After you flash a new rom, charge the phone to 100%, turn it off, remove the battery for 30 seconds, replace the battery, turn phone on, enjoy.
Anyone selling you the whole calibration thing is selling you voodoo.
hi
thanks for your reply
plz suggest me best battery app with battery saving feature , suggestion on what we can do with remaining battery , expected full time charge , complete graph or battery usage history by apps?
paid or free , tell me best one
thank you
There's lots of battery apps on Google Play, there's no such thing as the best one, go have a look under the Tools section in Apps (you'll also find some under productivity). Stay away from apps like Juice Defender that claim to save you battery by doing things automatically which you can do yourself in two seconds, these have been proven time & again on XDA to use more juice than they save.
ivl try battery monitor
thank you
No probs ;-)

Wouldn't that procedure above be considered calibrating the battery? LOL. J/K. Couldn't resist .

actually it cannot. this way you only help the system in your phone recognize full capacity of battery (which is not even full because not one battery works at it's full capacity - but it's fullest you will get at this point of your battery life). when it's about calibrating - listen to MistahBungle - it's all voodoo. you cannot calibrate li-ion battery unless you kill it and then revive. by killing it I don't mean depleting it in your phone, because even when phone shows the battery is fully depleted it's really not - there is still some juice in it. you'd have to use e.g. special charger which can drawn juice out of battery and make it really empty. only then your battery is dead and useless. you may revive it by applying cca. 5V but actually it not always works. so you cannot calibrate your battery in home environment.
what you can do is "re-calibrating" so called fuel gauge (description under links given below) and you may also help your system recognize the real state of your battery charge. sometimes it happens that systems readings are wrong and battery is on 85% but system is reading it as 50 or 100%. to help it read battery chip correctly you do the thing MistahBungle so helpfully described. sometimes you even don't have to do it but wait 2-3 charging cycles and system will adjust it's reading itself. by charging cycles I mean charging like from 20-100%. why not from 0%? because even if it's not a real depletion state, li-ion batteries doesn't like the state of being discharged too much.

and is there any way to stop auto startups of apps?i have around 200apps and most of them i use around once a day or not even once
i use android assistant to manage startup but it does on boot and after some time if i check running apps most of apps will be there running
is there any app to block it running automatically? not just at startup ? full control like anything?
thank you
actually I cannot help with that. I don't use such a software and really don't believe in it. but, the fact is that I do not use so many apps. other fact is that surely there is some useful software that could help you with that task, i just do not use one and personally I'm not interested in it. I know that perhaps the best method is to freeze them with titanium but if you use these apps from time to time then it would become complicated and not worth the effort.
still I have few questions:
why would you like to stop them from working? do they drain your battery? if so then check your logs with bbs and find out which ones are draining, try to change their setting or get rid of them, or at least close only these ones. long time ago I was fighting with some apps that I do not use often and they start themselves from time to time. I didn't want to get rid of them, so before every night I was killing them one-by-one from applications menu (actually most of them didn't wake up until I ran them myself). finally, after many tests I got to the point that it doesn't make any difference. apps I was killing, even if running, didn't use any recourses, didn't produce wakelocks, they were just using some RAM. and if it is the reason of your concern then do not be worried - they may use as much RAM as they want - android will free RAM when it will need it.
now I do not kill any apps and by night I lose 0-2% of battery which is my only concern - what should we care more? CPU, RAM - let it work as long as it doesn't stop us from enjoying our phone and make a usage of it uncomfortable.
and if you're worried about packet data then you may limit it for each app using system menu in ICS.

Thanks dude. I also have the similar problem. I have spent months on it without any improvement. Now I'm quite frustrated and not optimistic on the solution you have provided towards my issue, but your decription gives me a lot of clue.
But my problem is even more tricky, I would like to share it here so see if anyone have met it before, or if I need to start a new thread to deal with it:
The problem can be generally decribed as below:
1. When the battery is fully charged, unplug and consume the juice until the level reach around 30%, then the phone is shut down automatically; after I plugin the power and restart the phone, the battery level is displayed as 0%;
2. After charging for a while from 0% , restart the phone and you will see the battery level directly goes back to 50%, but still with very low voltage;
3. Changing with a new battery won't solve the issue -- though the new battery itself may also have problem(not sure if it is genuine), but I don't think a fake battery and an old battery should behave almost the same, so I don't think it is the battery's problem; criticize if I'm wrong
4. Re-flashing a new rom won't solve the issue either. I have tried different CM9 nightlies and now I'm using CM10 nightlies, none of them is immune to the problem;
5. Clear the battery state won't solve the problem. It is hard to say whether it improves the situation at least a tiny bit. I mean it may work somehow, e.g. My phone used to be shut down at 50% battery level and now it can last to 36%. But it never totally solve the problem once and for all, so I still don't trust this caliberation thing may work.
I hope I have clearly stated my issue. I'm so at the end of my patience, this little bastard have been always torturing me You guys are the last I can count on I really hope I came here earlier so as not to have wasted so much time.
Hello everyone whenever i check bbs or gsam battery widget or wakelock detector there is no wakelock but the thing is that after 1 hour or so whenever i check my phone i lose 5-6 % .That means not even 1 day of standby
what could be the problem? i've tried like 20 roms and different kernels and still have this issue..
Im currently using walkman style rom and Kappa kernel

Which is your current ROM and kernel?
To fix this you could do the following
1. Reflash the phone's stock OS(preferably GB or ICS)
2.Just in case re-calibrate the battery via cwm or an app.
3.Run with the stock ROM for a week without installing any other apps.GO STOCK!
With this you can know if the problem is ROM or Kernel or you battery.

For all the smart boys out there, there is NO such thing as battery calibration. All that kind of stuff on the internet is complete, apologizes for my language, bull****.

Force deleting the batterystats.bin file is battery calibration. This is the closest thing a user can do to properly set up the battery monitor chip.
The file is used by the chip set which monitors the voltage across the battery to give out the % reading. It's normally reset by the chip itself if we charge the phone up to 95%+ each time. But improper flashing of roms will cause residue data to remain resulting in a error in the %.

Wrong. I have no idea, where you are taking this from, but this is completely false.
Today's myth debunking:
"The battery indicator in the status/notification bar is a reflection of the batterystats.bin file in the data/system/ directory."
No, it does not.
This file is used to maintain, across reboots, low-level data about the kinds of operations the device and your apps are doing between battery changes. That is, it is solely used to compute the blame for battery usage shown in the "Battery Use" UI in settings.
That is, it has deeply significant things like "app X held a wake lock for 2 minutes" and "the screen was on at 60% brightness for 10 minutes."
It has no impact on the current battery level shown to you.
It has no impact on your battery life.
Deleting it is not going to do anything to make your more device more fantastic and wonderful... well, unless you have some deep hatred for seeing anything shown in the battery usage UI. And anyway, it is reset every time you unplug from power with a relatively full charge (thus why the battery usage UI data resets at that point), so this would be a much easier way to make it go away.

So, all those stories, which you have heard about batterystats.bin file removal improves battery life is false and just a placebo.

Well thank you. You've completely changed my conceptions about battery! I apologize for any wrong information I may have provided. So I ask you is there any other way?
Right now my phone switches of on 10% all these days I've believed it was just a file problem but since on reading the article I can see it's not. So is there any other way to properly make the phone show the proper battery left %?
Mine dies just at 10% is there any way to correct the problem?

You can try deleting the batterystats.bin file, but I am 100% percent sure, that this won't fix your problem.
Though I have not been active on this section of the forum, I can not provide any other solution. I know there have been other threads, you might want to try searching on the forum, if there are any solutions.
