Well, try to discharge your phone until it fully drained, and charge your phone until it reaches to 100%, should be powered of,unplug, then use it the normal way, until it fully discharge and do the same, for at least 3 charging cycles.
Or charge your phone to 100% then before unplugging, go to /data/system and removed batterystats.bin.
I hope it will help, the first step is I think the most accurate, than using such apps.
Thank you,

Best is to charge and discharge for a few times without whiping battery stats. It will calibrate itself. Whiping battery stats to incrase battery life was already proven several times to be a myth. The stats will be anyway overwritten completely after a few cycles. So whiping them even can make things worse till the new stats are filled.
However under some circumstates this might help, but you must take into account it can first drain more till the stats are filled and you get accurate readings. I only once whiped the stats while changing the battery from a LI-Ion to a LI-Polymer because the LI-Polymer is behaving a bit different.
More important is to care about the full gaugue, because this can show incorrect values and fill the battery stats with these. This is for example the case if pluging in the charger at 30% and rebooting and getting after the reboot for example 70% displayed. It´s simply impossible the battery gets charged by about 40% within 1 or 2 minutes while it´s booting. The same often happens when going into CWM recovery and rebooting afterwards. Therefore I always charge the phone to 100% before going into recovery and keep the phone pluged into the charger while for example doing a backup or flashing a kernel.
There are many reasons why the battery can´t last that long. For example apps or services keeping you phone awake, wifi or mobile data being enabled the whole time, or the battery itself going down the hills. For me wifi is draining a lot, even with a reduced voltage in the kernel. One of the services that can cause high battery drain is the media server and media scanner if it can´t handle the media type or index the media names due to some SQL prefixes included in the names.
But when speaking about the kernel it looks like Arco fixed the high battery drain issue in the final CM9. I flashed it last night and il looks like it´s draining just as much as if I were using RC2 or RC3 with Arcos stock 2.6 kernel.

Calibration with apps by wiping battery stats is useless.

Battery in cm9 eol and cm9 rc3
Does battery of cm9 eol same like battery of cm9 rc 3 with honeyx's kernel and also how long the battery can last from 100% to 0%?
Bcoz I feel like my battery drop frm 100% until 87% in about 1 hour use cm9 rc3 with honeyx 's kernel...

It´s nearly the same. Not exactly the same, but nearly the same, so it will not become better if you switch to CM9 EOL but probably a little bit worse. All depends to your battery health and how you are using your device.
I find the 2.6 kernel still a little bit better when it comes to battery life than the one in the final CM9, but since the differences are really small I´m already using the final release with a modified kernel.
This kernel has a few more optimizations for battery life and I will launch it quite soon after some more tests are done.
Don´t know how you are using your device and what apps are installed on your phone, but if your WiFi and Mobile Data is always on, there are a lot of apps running in the background and you are very often using your phone, your results are still very good.
Else better replace your battery with a new one, as there is no kernel that will turn a bad battery into a shiny new one.

Sure, you just have to wait a bit till I release it as i need to test it for stability before launching it and am doing this for a couple of days to be 100% sure.

Great,thanx u for share ur kernel..i can't waiting to using it
but i dont understand to battery life extender
" Use RootExplorer and go to: '/sys/class/misc/batterylifeextender'. Change the value in 'charging_limit' for example to 90 (default 100). This will set a limit for the capacity to which the battery will be charged. So in this example the battery will be charged to 90%.
----------------------------------------------------
After flashing the kernel whipe your cache and dalvik cache and fix permissions."
Mean that change value before flash kernel??

No problem, but wrong thread. You can´t change this value before flashing the kernel as it doesn´t exist before flashing a kernel that supports battery life eXtender. So only possible to change this after flashing it.

Just change it without rebooting afterwards. If you reboot after changing this value, it will be reset to the default value (100).
So to permamently change this value on each reboot you need to use a tool that will do this for you at each booting. Don´t remember which app is actually supporting BLX, but there is one that will do this for you.

No. Go to CWM recovery. Flash kernel. Stay in CWM Recovery, whipe cache, whipe dalvik cache and fix permissions. Reboot. Then you can use root explorer to change the BLX value once it has booted.

[Q] How to change sync frequency in MIUI ROM 1.2.4?

I just flashed MIUI last night and noticed that my battery is being sucked dry pretty fast. I suspected that it is due to sync being switched on. Where can I make adjustments to the frequencies of the sync?
Either from the app or Settings>Personal>Accounts & Sync
Although I didn't have ANYTHING setup last night when trying it and lost 6% in about 10 mins - something's not right
Try resetting your battery indicator http://www.miui-au.com/howtos/reset-battery-indicator/. It is also recomended somewhere on the miui-au.com site to not charge your phone while flashing because it is somehow disruptive for the indicator.
I know all that, I wipe:
data/cache
dalvik-cache
battery stats
rotation settings
before flashing ANY ROM. Battery life is still crap

The weird thing is I wasn't charging the battery while flashing. I find it a bit surprising for MIUI 1.2.4 to be quite a beast in battery usage.

What would you consider a good battery life?? I flashed to 1.2.4 and it seems to last me all day without any problems?BUt I have noticed slight 5%-8% drop in the 1st hour or so but then it stablises throughtout the day. Ive not tweaked my phone with setCPU and I dont intend to either.
Something is rly wrong with your MIUI. Anyway, never use that Kernel which comes with miui. Use Vork or Coutts Kernel.
pls download current widget from market and test how much mA it drains in "screen off". im using miui-au 1.2.4 r2 with vork kernel and im losing 1% per our with wifi, sync and gps on. it uses 4-5 mA with screen off.
With previous MIUI builds, and with my own ROM I'm using now, I can go from 7:30am til midnight and still be on circa 50% battery. This is with my normal weekday usage. It goes down to about 30% by end of the day on weekends as I use the phone more
This build drops 5% in a few minutes and I just don't see that as being any good

I don't need to download anything, the ROM was dropping battery with NOTHING setup except for Wi-Fi. I didn't even setup my Gmail account to get my contacts!!
I think I can skip the obvious as I know full well what I'm doing and never had this issue with previous MIUI builds, and I never use the stock kernel - I always go for a Coutts one before first boot

50ma battery drain on stock and cm7

Hi wildfire users,
my girlfriend got her wildfire yesterday.
The first thing I've fine, was to root it and check the standby battery drain.
It was between 27 and 50ma in AIRPLANE mode, without sometimes at 120??
My device got 1-2 in airplane and 3-5 without.
Thought it would getting better after flashing cm7, took the rc1...not really.
Any suggestions? Iam an experienced android user, but my options are running out, what else I can do.
What I've done:
Checked drain with current widget,
checked partial wakelocks with spare parts-seems okay.
Uninstalled all custom user apps I had installed.
Read here, that reflashing the radio fixes some issues...didn't tried that yet.
Any other ideas?
What drainages do you've got?
Waiting for your answers.
Edit: perhaps it will help to let it charge it to 100% and check again...maybe let it also discharge one time ^^.¿?
....think i was perhaps a bit over motivated...

Battety drain will be above normal just after flashing a ROM. You need to make a full charge and then go to recovery and wipe the battery status.
Then do few complete charge-discharge cycles. Then it will be definitely better than stock rom. And use CPU settings in smart way. Work on the minimum setting and governor. Also depends on other factors like live wallpapers etc..,

Battery calibration gives accurate reading only, it will not improve the weared out battery.
When shifting between roms, the battery will not give accurate reading because not all roms utilize the battery in the same manner (Rom saves the details in batterystats.bin file). So, what if it gives wrong reading. There might be a possibility that it shows 100% even when not fully charged. So we think battery drains faster, but the fact is we haven't charged it fully. (correct me for any errors).
Sent from my HTC Wildfire using XDA App
Yes showing 100% wrongly must be the only situation where battery calibration be blamed. But 8-10 hrs of charging from deep-down-zero should definitely make it full, right ?
Whats your general time taken for charging in standby mode (WiFi, Mobile Data, Bluetooth Off).
I am experiencing heavy battery drain with WiFi, since I installed Sunabh ROM. (He adds a switch off wifi notification to hide this fault. Cunning.)
Any solutions ? May be re-flash the radio or change the kernel ?
Dude, attack the CID bug.
I resolved my issue without even switching of my phone once, let alone flashing anything.

Battery drain even when arc is turned off

Hi
since a few time my arc s is draining battery in airplane mode at night (20-30%). I am using Arconium 3c.
- So I tried to come back to Arconium 2.4 (it was ok before) : the same (20-30%)
- So I tried to turn off the phone and the same : the battery lost about 20% during the night.
The battery drain used to be great in airplane mode (2-3% per night) few months ago when I started using arconium. So I don't think it is because of this rom.
Maybe my battery is bad? Or something else?
How old is the phone
In wich interval you recharg it
Check out the battery usage under settings and look if you have installed any program that uses much energy from ur battery
I think the easiest way is to try the other ROM first. If this problem still occur, maybe you have to check your battery
I also had that problem but with this stay good:
Use this kernel
http://forum.xda-developers.com/showthread.php?t=1680793
Use this Baseband
http://puu.sh/pAgX
Use this app https://play.google.com/store/apps/details?id=it.sineo.android.noFrillsCPU
For me is the best option
Well, thank for your answers. So the phone is 6 months old and I don't understand why if I change my ROM or my kernel it would do anything? Because the battery drain occurs even if my phone is off. Is there a way to check is my battery is damaged?
Tonight I will try to remove the battery for the night.
PS: I checked that I have no weird application that is draining battery...
jap check what happens if you put the battery out for a night
but you should even check the other kernel

Well, I am back to Arconium 2.4 (with .562 firmware) so the other kernel would not work correctly as it is for 4.1.B.0.431, would it?
I guess I should try .431 based kernel if I come back to Arconium 3c.
I have tried battery mix to check if there were an app draining my battery when phone is truned on but nothing (appart from system android) seem to consumes much battery.
Ok
well but if you really want to know what i think i would say (not assure) that it depends on the rom cus some time ago i had a2 different phones (galaxy spica and galaxy gio) wich i flashed to spicagenmod and the gio to cm7 and i recognized that the battery usage increased in a huge amount
u say that even if you turn of the phone it seems to be that you get a loss of power in your battery
the spica often crashed and i had to restart it (used many experimental features)and after the restart i had a huge los of batery power....
some roms have problems updating you the current battery status and if you restart it it seems that it had taken much battery
if you really want to safe power you may search for a undervolted kernel
Hope that really finished ur problem =)
Ok I think I understand what you mean about the voltage. ie at 100% the voltage is about 4178mv and now at 41% the voltage is 3775mv (with battery calibration app). So it seems to be not linear.
So I am going to flash kernel as recommended previously. And Do I have to reflash rom and baseband after flashing new kernel?
depends on wheather the kernel works with ur rom
what do you mean? I flash new kernel, reboot phone and if it does not work, I Reflash the rom? Maybe it risks to brick?

0% on the lithium battery is not 0v it is more like 3v or so... depends on the battery.
if a lithium battery measures 0v it is DEAD.

[Q] Battery charging too fast

Hi guys.
I have a strange problem. My Gio charges from 3% to 100% in 3 minutes. It says fully charged...
Of course it's not real charging, if i unplug it, and start to play a game or just see my mails with wifi, it consumes that 100% on 5-10 minutes...
I've tried to charge the phone all night and the result is 2-3h of working time. If i use power consuming apps, like games, than it's just half an hour... I think that the phone stops somehow the charging process if it reaches to 100%.
I've tried to calibrate the battery, with program from market, and wiping batterystats from CWM too... It didn't help...
The strange thing is, that last week it worked well. Now something happened and it's ruinig my life...
I had THIS ROM when it started.
I've changed to THIS ROM, and it didn't solve the problem. All caches were wiped during flashing...
Any ideas?
Thanks for any help!
Anybody? Please...

Hm you said you tried to calibrate the battery so it`s weird. I have sometimes the same problem but after a calibration it is fixed. I can only recommend to charge it overnight , make sure you`re not overclocking it , make sure you don`t use wifi , mobile data , gps , see if there`s an improvement keep it only with calls and messaging for 1 day see how that goes. Check also the battery maybe it has a spillage altough i don`t think that`s the case. Sorry that`s all i can say
Thanks for the advices.
I've just set the CPU governor to smartassv2. It was on Ondemand. Now I can discharge the phone with playing within 15 minutes. It's better than it was on ondemand...
I will try to use it like a regular phone, let's see how it works...

also remove any apps or games you have installed since you encountered this problem, I have tried enhanced rom it gives a stable battery life, but its worth changing to a different rom like cm 7.2 by phiexz, I am currently using it and it gives a good battery life.

I'm waiting for a new battery, but if you want to keep your phone alive up to then:
- flash a stock ROM
- install as few apps as you can (I've G+, Stream (FB client), FB messanger, Viber, WhatsApp, App Cache Cleaner, AppZorter and xda app, nothing else T_T)
- do NOT use kernel different from stock
- hope you good luck because first times battery will be strange, after some full usage and discharge now I've the battery life I told before
Hope this could help
I have galaxy gio and it problem is whaen i charge my galaxy gio 3 min later to touch to 100 percent and then i plug out and on it then it show battery is zero

[Q] Terrible battery life on jellybean aosp roms

My battery life is considerably worse on jellybean aosp roms (I tried both the 4.1 and 4.2 version) than it was with stock ICS, and stock jellybean with sense, I'm sure that the battery lasted at least twice as much than it does now. I'm getting around 7-8 hours with a screen time of 2 - 2.5 hours at maxiumum, screen brightness at 50%, location turned off. It's clearly a software problem since the battery life with stock rom is so much better. Something must be wrong since everyone is reporting great battery life with the latest jellybean aosp rom.

I think you maybe hurrying to a conclusion.
After you flash the flash the ROM, wipe battery stats in cwm. Then let the ROM settle ( atleast 2 charge cycles ) .
Then see if you have the same battery problem

I'm on ice cold jelly 2.2 with the XML kernel #141repacked for the ROM. I get a steady 3 hours screen on time. Give that combo a try. Also the first few days the kernel and ROM have to settle so don't be too quick to judge it.

Thank you so much! I have deleted the battery stats file in cwm and it is immediately obvious that the battery life has improved.I can't believe how easy the fix was.
Sorry for the replies, but: the battery stats wipe is useless...
The file that you've removed is a file which contains the statics of battery.
It has nothing to do with the battery life, Google has confirmed this.
In fact, in TWRP and 4EXT recovery this wipe there isn't.
However, i think you have to calibrate your battery with some charge cycles

Guich, what i talked about was not fixing battery, just fixing the readings.
Example : especially on AOSP roms, if u put on charge, after some time green LED shows (meaning charge full) BUT battery bar is stuck at a lower level ( Example 76 ) .
And the bar doesnt move forward even after you keep it on charge even longer.
So i tried a battery stats wipe in cwm and then when i booted back, it properly showed 100%.
So what i recommended was to delete previous stats ( of different ROM which were carried into this one).
So now the phone starts monitoring battery anew (with no cache).
Sorry if you misunderstood me.

I think this fact is random.
In fact, all aosp rom that i tried didn't have this problem
And, teorically, this file was delete when you made a full wipe.
In fact in TWRP recovery there isn't the wipe for the battery

Battery stats file should be deleted each full charge, though I have noticed my phone crash (my fault messing about with UV) and then my batter jump from 8% to 45% which is quite a jump lol

I'm familiar with CWM, but I cannot find it in advanced menu.
Is it because after I upgrading my HumberOS CM10.1 to AOSP 3.15?
I did a wipe clean. Everything. Fresh install.
It happened after I finished upgrading to AOSP ROM 3.15. My battery shows nothing even I charged it for a whole night.
Only 2% batt left while I'm typing this message. I have to connect my SGT7 to charger but nothing happened. It shows that it's charging but too bad, its not.
I've never encounter this problem before. It would be nice & I would be grateful if you sir can help me through this problem.
Thanks for replying.
