I faced some problems with ICS. Heavy Battery draining......
So I found a solution to that problem...
http://forum.xda-developers.com/showthread.php?t=1861229
The device needs to be at rest (turned off) for at least an hour when its empty and then when it charged back. This will let chip to make 2 open circuit voltage measurements.
How to make sure that device is discharged enough for calibration to take the place? If capacity is off big time then gauge may report SOC 30% but in the fact battery is in 70%, so chip will not execute calibration procedure.
The most sure way to check this is in terminal, execute this command:
cat /sys/class/power_supply/battery/voltage_now
or through adb:
adb shell cat /sys/class/power_supply/battery/voltage_now
your good discharged start point should be anything below 3700 (3.7V). If your device is telling that you have 0% capacity but voltage is more then 3700 then keep rebooting the device (this will refresh counter for a moment) or just boot in CWM and let device run/sit there for some time.
Then charge it with power adapter to 100%, you can check voltage at this point - should be around 4100, usually you should be good.
Then shutdown the device for another hour or two.
That's it. You should be good now unless you are still using certain custom kernels.
Simple method...::
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 the device and let it sit for 1 hour. (this is needed for the first measurement)
3. plug it to charger and charge it for 5 hours, full charge (90+%)...
4. disconnect the charger and let it sit for 1 hour in idle (shutdown state or in cwm). (this is needed for the second measurement)
5. boot up the device and test it, if your battery is still not calibrated you can flash back your backup and repeat calibration procedure.
But for me Compared to GB in ICS Battery drain is less, i am on Leaked ICS with Ardatdat's kernel and Pankaj's Deodexed ROM ...
Sorry for being a noob, but could you kindly explain what is terminal and how to use it?

Here, terminal in linux/android is just like command prompt in windows... Search for terminal emulator in play store... And google for further information...

You are lucky... My battery drained in 6 hours with no use... But.. When I callibrated by above method... I got more than a day... At the end of the day... I had 30% still left....:beer::thumbup:

Even if anyone does feel that.. He is getting good backup...
He should at least check the full charge voltage and zero charge voltage of battery to get confirmed that the battery is properly callibrated in your device...
You can check the voltage by following simple adb/emulator command as shown above....

Yup...
1.Drain it as low as possible....
2.Keep it off for an hour....
3.Charge it full...
4.Keep it off for another hour...
Measure the voltages while in CWM via your computer connected in usb mode with the galaxy r...
Use adb and put the command....
adb shell cat /sys/class/power_supply/battery/voltage_now
It will give you the current voltage...
With full charge the voltage should be around 4100mv..(milli volt)...
And with empty charge it should be at least less than 3700mv...

I accidentally drained my battery to 3250mv. But then I charged it to 100% which was around 4180mv. Still testing battery life
I discharge my phone till 1% and it's voltage says 3380 mV .... is it normal ?? do I need to follow procedure suggested ??
PS: I know it is given it should be less than 3700mV but wondering if 3380mV is too low / any problem ??

At 0% its supposed to be around 3400mv. So I would say it's fine.

Its ok... But...dont repeat it again and again...otherwise the battery life cycles will reduce....
for e.g. If ours has 1000 charge cycles... It may get reduced to 800 or so....
Dont drain the battery excessively, otherwise you might have to buy a new one sooner........

sorry for a bit off topic ... wondering which way battery will last longer :
1) charge till 100% --> use it till lowest level almost less then 5% ( no change in-between) --> then charge till almost full ( no discharge before full change) --> less charging cycles I guess
2) charge whenever get a chance so battery level will remain in middle ( neither fully discharge nor fully discharge ) ---> will not it consume charging cycle fast

First of all... The method is for one time calibration only... Dont repeat it more than twice... It will cause unnecessary strain on your battery.
The first method u mentioned will give u more battery cycles...
But, instead of discharging it to 5%... Get the charger as soon as you have below 15%.....

So i have decided to say something, and to write a little "MY GUIDE" :
First of all, this thread is due my AWESOME BATTERY LIFE
I'm running Insert Coin 3.4.1 with Bricked 1.4r1 Kernel.
I have done following steps :
0) First of all, you have to drain your phone dry (dead, till it powers down itself).Turn of fast boot (this is very important)
1) Turn your device ON and Charge the device for 8 hours or more
2) Unplug the device and Turn the phone OFF and charge for 1 hour
4) I wiped battery stats then when finishing those 1-3 steps.
5) Used phone regular.
6) For next 2 charging cycles you have to again discharge your phone untill it powers down itself
7) Charge it for 8 hours (i did it overnight)
Click to expand...
Click to collapse
After that 2 more full charging cycles you can charge your phone as much as you want and whenever you want. Charge it on every percent..
When you are charging your phone (after all 3 cycles), try to charge it when it drops under 30% and to charge it untill fully charged green light.
But i understand that sometimes you cant manage to charge it fully and when it is under 30%. Never mind. It is recommended but it is not required every time.
I'm trying to completely discharge and charge over 8 hours once per 1 or 2 weeks.
And after all this i have very good battery life.
With moderate use, my battery lasts over 24 hours (moderate use - lotof voice calls, lot of text messaging (SMS), checking on foursquare and little surfing over mobile network (HDSPA), alot of surfing over home WiFi.
In standby it cant be compared to anything i have heard here : I have 1% per 3 hours drain in stanby.. maybe even more hours, i cant properly determine but overnight when it is not charging i loose not more than 4-5 %).
My setup on phone is following :
1. Manual setup of brightness (im thinking of getting baadnewz auto brightness tweak)
2. All options in sound settings ( increase in pocket mode, flip over for speakerphone, quiet ring on pickup etc) are disabled.
3. Network is on GSM only. When i need HDSPA i change it manualy.
4. Auto sync is off.
5. Vibrate feedback and typing vibration is ON (i cant live without it ).
6. Dont have any battery saving applcation (juice defender, watchdog )
7. I dont have any mA monitor . Im fine without looking at wrong values monitored . I just have BattStatts (percentage shower).

Click to collapse
I hope you like this, and i hope this will help to some one here.
After all this time on this forum (over year and a half), a lot of people here helped me a lot with my problems with my previous device (HD2) and with my current device (Sensation), so i was in need to try to help other people with major problem (battery).
If you want, put this thread sticky, move it wherever you like, if it is helpfull.
Best regards folks.

p.s. If this helped in any way, or you find this post(guide) useful, don't be lazy to click thanks button I thank to you all for your support
Thanks for the info!
I just flashed Faux 0.2.4b kernel on my ARHD 4.1.5, gonna try this whenever I have enough time
Would appreciate thanks button hit
And , yes, try it.. and report results pelease
For example.. I charged my phone today, took it of charger 10am..
With moderate use i have 98 percents now.. It is awsome
That's called bump charging. It may increase short term battery life, but depletes long term battery life. HTC recommended you do this ONCE every couple of months.
Plus our batteries are lithium ion, so doing full charge/discharge cycles will practically have no effect. You could do it just to calibrate it wight the phone, so as the phone "knows" what's 100% & 0%. But other than that, fully discharging these batteries could harm them. These batteries like partial discharge. So charging them when they get to around say, 30% is more convenient for them.
Just thought I'd let you know
Sent from my HTC Sensation Z710e
I didnt said to repeat this every day or week..
I said you should have 2 full charge discharge only once after u done 1st couple of steps..
Full charge and discharge once per 2 weeks will, in no way, harm our phones..
And i said
When you are charging your phone (after all 3 cycles), try to charge it when it drops under 30% and to charge it untill fully charged green light.

I have done steps from above, and i have great battery life.. short and long..
I know our batteries are lithium ion, and i know a bit about them (im finishing Electrical engeneering College here in Serbia (most difficult ever ))..

To recap..
This method CANT harm your battery or device.. It can only help your battery life.. Try it.. See it yourself
Thank you for your guide.

Woah, take it easy my Serbian friend. All that I'm doing, is stating the facts & trying to help you understand that what you hear about charge/discharge cycles are just carryovers from previous batteries where it was good to be do several full drain/recharge cycles.
Here's a perfectly clear explanation of the differences coming from experts: http://androidforums.com/incredible-tips-tricks/69534-battery-charging-myths.html
And a more detailed one:
http://batteryuniversity.com/learn/article/charging_lithium_ion_batteries
What you experienced is bump charging, like I said, it may increase short term battery life, but WILL decrease its long term usability. So come on, this is a community, we learn from one another
@mzmo :
Mate.. You got me wrong. I appreciate your post in this thread . I find it useful. Ofcourse we learn from each other.
The facts ive put in OP thread are facts from my phone directly . First steps of guide was in mail HTC has responded to me.
So, all in all, thanks for your posts ,and for your future posts.. I find them all like big contribute to XDA community.. After all, i made this thread due to that

Which bricked kernel version is better for insertcoin 3.4.3, v1.4 or v1.5
Thx
Thanks for the info.. very helpful...... i will try it out frm today. i have a huge battery drain
using ARHD 4.1.7 with faux latest kernel
Though Most of you Might know this already But I'll post it for the new Users out there
So you have flashed your Rom Recently and are finding some trouble with your battery?
Does it dies too quickly? or you see those numbers going down very Soon?
There might be some Other Issues related to Battery drainage but most common problem the user might experience after flashing quite a few ROM's is Mis- callibration of the battery
To fix this install a market app known as battery callibration
https://market.android.com/details?id=com.nema.batterycalibration&feature=search_result#?t=W251bGwsMSwxLDEsImNvbS5uZW1hLmJhdHRlcnljYWxpYnJhdGlvbiJd
You need to have a ROOTED device for that
program does it by removing the batterystats.bin system file. The OS generates a new clean batterystats file soon, thus any fake information from the previous ROM is removed.
When you reboot the phone after calibration a new batterystats.bin is created
IMPORTANT after calibration let your phone discharge to 0% and then charge it to 100% without break
DO IT AT YOUR OWN RISK (although None is involved) I'm NOT RESPONSIBLE FOR
ANY SORT OF DAMAGE DONE.
Hope this helps you guys
This can also be done via CWM usinge the delete battery stats option.

Hey..it works,thanks for your efort in researching this
I'm quite desperate coz ever since I'm installing creed 1.7 seems like my bettery drain very fast,too bad coz I like this ROM. Last night I charged it to 100%,then I go to sleep(so my HH is idle) but when I woke up 3 hours later,my battery stat already drop to 84%,strange. So I try plugged out my battery for 5 mins and voila..now it's written 53% but it's been like that for half hour so maybe it's quite stable now. Thanks again dude
since 13 months i m using fit bro and the most annoying thing of android was battery backup so researched almost all sites of android and lion baterry ....checked alll methods of battery boosting from apps and ram clearance,...the battery stats.bin bro yup that you dont have to take care its android system which adjust itself and recalibrate when you make your android without power means no battery for a while and when you insert it again the system itself recognizes....killing your battery specialy lion reduces its self life also its the number of cycles so whenever you charge charge your phone to fullest not like every 5 min you are charging your phone once a day to the fullest just check what i said bro its really works just believe and c

However, as she explains, that’s not the case. Because those battery stats, stored in the batterystats.bin file, are only used to maintain information about what is using the battery when not recharging. That is, it essentially holds the information displayed in the Settings > Battery screen. Nothing more, nothing less. Thus:
It has no impact on the current battery level shown to you.
It has no impact on your battery life.

hi guys. I'm having a pretty simple problem - my phone will charge up to full according to the battery icon when it's off, and when it is on it says charged on the lockscreen, but it says 96% on the battery widget that I have and as soon as I unplug it it drops to 96% on the lock screen. I know this is a problem common if a tomorrow was flashed with a not full batt, but I haven't flashed anything. I have only rooted. Deleting batterystats .bin didn't seem to do anything.
Thanks in advance. Hopefully it's an easy fix.
Sent from my rooted Nexus S using XDA App
No problem for you. It's made to charge up to 96% to "extend battery life" or whatever. Don't worry about it.
Some kernels provide a cosmetic fix that shows 100% charged, but it charges only to 96%. Another alternative is to bump charge the battery (explained here on the forums) but I don't see why you would do that. Not much to gain anyway.

it's safety feature in order to protect battery
That extra 4% - not that significant. I've tried to bump it to 100% (have to wait significantly long), but not much gained in term of extra uptime.

acutally , for Li-ion battery , if you everytime drain it to 0% or charge it to 100%, would damage it and short its lifetime...
If you wan't charge 100% use a custom kernel or Rom.

its not really a 100% with those kernels, he will still actually charge to his 95% even though itll say 100%. its just a cosmetic fix. if you actually want to see 100%, charge it to your normal 95% then charge the rest of the way with your screen on. itll eventually hit 100%.
i finally found the answer to my battery

So i went to SSC and they: (stock GB, 0 flash counters)
- take my phone without documents on free guarantees (only box)
- I must come back for that phone in this friday
This above is for + but:
- they **** that work because I have in my ducuments copy a lot of bugs! (street , town)
- they checked my speaker in noisy room (it did not take nearly as booming)
- for those guys after restart when phone loses 30% battery power is normal!
So I go after tomorrow for my phone and we will see ( They will make updates to JB! and they change speaker/ charging module)
Photo for proof attached
If they dont repair my phone I do not buy samsung phone NEVER AGAIN!
EDIT: 3 hours waiting for a response about taking my phone!
EDIT 2: that 3500mAh battery must be loaded 8 hours to get 100% form 0%. (standard charger )
I really want to know what the whole battery dropping after restart thing is about, forever happening to me and sometimes the battery completely dies. It was the same on my original Ace S5830 I got a few years ago.
If you find out, please tell! haha.
After receiving the reply I upload it here
Have nfc version and ni problems with battery with much using and sometimes little bit playing i rech two days
I dont have problem with battery (any) but with phone hardware
I must agree with you guys regarding battery drain. It's suspicios and I am also aware of a fast battery drain from 100% to 65% in just a couple of hours, or very fast after a restart.
Maybe this is the way android should work. I was thinking there was a problem with my phone, but seeing similar behaviour with yours, it must be something related to the android system.
I'm on JB me1 and i haven't this battery dran problem. After the night i just lose 3-7% battery
When I have 100% and I off my phone and turn on battery go down to 50-60% immediately in one secund! It must by hardware foult...this is not normaly working android, for me
Really i don't have sth like that so that isn't real android

well i dont have that
sometimes when i reboot my phone it goes from 45% to 47%
and some times from 45% to 44%
This is ok
I thought that is not really a battery draining. But it just about battery calibrating. Your phone need to calibrate the battery. Thats the problem.

lol actually "calibrating" is just a myth. It doesn't really do anything.

Really??
However, I've never done any battery calibrating..but I read in some thread, need to calibrate the battery, so there will be no battery misdisplay on the battery icon...logically, I thought, our devices will some time miscommunicate with the battery because there are no battery parameter to make the system understand how much the battery stored....
But I don't know if it just a myth...

its normal to see 99% when unplugging from charger, 3%-10%(Max) drop on rebooting. Battery is usually inaccurate after charging, what I do is plug it in then reboot. then it displays the right value after unplugging, usually my battery status is really inaccurate but it returns to normal afterwards (it'll show charging icon even when unplugged and charge to 100 then stops and returns to real level). I don't believe in this calibrations and have found enough proof its useless, I think most xda users agree too. Try searching some threads.
