is it usefull to use a Battery Calibrator?
I have done almost always battery calibration with all my androids.
-Battery Calibration from Market
-Load battery full, do calibration
-Use battery till phone shutdown
-Load battery full when its turned off
After these steps regular use and battery acts like it should
In CWM go to advanced - batery calibration
do this with 100 procent batery
let the phone run dry
charge 100 procent while phon eis still turned of.
You can repeat this until it is good again
good luck
i try latest doomkernel,from the review it said that battery use just average 1%per hour,but when i try it,my battery drain faster,in 6hour my phone dead,so i think maybe i miscalibrate,ok i will try all the method above,thnx for help

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..,

How does calibration the battery prevent from it from draining faster ?.
Suggest some thing that makes sense.

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.
Running for more than 2 days now. \m/
Hi! Before i have got a drain of 3-6 mA with most of the roms, but suddenly all roms dain 16-20 mA. No matter if it is MIUI , cm7 or sense roms. They all have the same drain .. is my battery bad ?
Got my phone waterdamaged 2 weeks ago , but this bad battery time started yesterday...
First you need to calibrate the battery.
Charge your phone until Current Widget shows 0mA. Then go into recovery and delete battery stats. Let the phone discharge until it shuts down by itself, then charge until it is back to 0mA. That will calibrate the battery.
Secondly, new ROM's do take a few days to "learn" how to use the battery most efficiently so you wont get the best battery life instantly.

I know that ROM´s need a few days , but i have waited a few days ,and noticed that it is allways the same drain... But i will try calibrate my battery next
And please make sure that during the period of charging it the second time that you do not take it off the charger. That will mess up the calibration and you will have to start all over again.
you might want to try a new radio too
same for me. I tried everything I could.
I tried these roms:
-coredroid
-ARHD
-honey
-virtuous
-MIUI(current)
I tried these methods:
-multiple new recommended radio + ril
-battery calibration app + clear battery stats(recovery) @ 100%.
-full wipe 1.5
-re-root(hack kit v12.3)
-different kernels
When I first rooted my phone battery was perfect on any roms until I flashed ARHD,thats when my battery drainage happened.

how many hours you are getting now....with regular usage ????
I'm getting the same here... Started with ARDH too, then LeeDroid, now Virtuous.
Clean installs each time, apps restored using Titanium. Also re-flashed the recommended Radios too and calibrated the battery once.
Current drain is 15% / hour on Standby ~70+mA.
I noticed no unusal Wake Locks either.
I'm loving Virtuous, but thinking to go back to stock if the new Viruous update doesn't solve this.
Just whilst typing this I lost 2% :-(
Yeah this is no fun...

After flashing a rom.
I use the phone till it dies,then fully recharge and wipe batt stats in cwm
After a couple of days ,when the rom has settled .batt life is good.
Have never used a third party app or any long winded cycle methods and always get a 20 + hours of avg use.
Hope that helps

Simply using your phone will " calibrate " your battery.
When you fully charge your phone the batt stat is erased automatically.
how that helps do a google for "battery calibration myth debunk"

Ok so ive installed alot of custom roms on my wildfire s and on all of them my battery life sucks. If im on wifi my battery goes down 10 to 15% in like 2 to 3 minuets. Do you guys think its because of the roms or i just need a new battery. Please help.
Type in the call menu : *#*#4636#*#* and go to battery menu.Wrote there all the informations.
Do you full charge your phone ?(about 2-3 hours)
Try to delete the batterystats.bin file via CWM.
If i helped you,click "Thank's" button.Have a nice day

10 - 15 % in 2 minutes? WTF?
Are you sure your battery isn't faulty?
Even in worst conditions my battery never drained that fast.
Anyways here are some tips:
-Charge phone to 100%
Go to CWM and delete battery stats.
- Dial: *#*#4636#*#*
Go to phone information, In preffered network type Select GSM auto PRL.
- Use juice defender or something which would turn off wifi whenever its not being used.
- Make sure all the accounts aren't set to push as it takes a lot of battery.
- End processes by going to Apps-> Running services.
- Don't use heavy widgets on homescreen or launchers.
- Brightness to auto and timeout time must be less.
I could remember just these. But I guess if it's true that your battery is draining that fast most probably your battery is faulty. Get a new one.
sounds like a faulty battery.
Kill/Uninstall Apps
Yeah, I had this problem :/
What I did was
- download a battery saver app, It closes mobile networks when you're not using them.
- Set the screen to a low but visible setting
- Uninstall some of the memory draining apps
- and kill some of the RAM munching apps.
Hope this works :L
ill try some of them
Don't download a battery saver app, it'll just use cpu cycles and battery even more.
Manually turn off mobile data and wifi when you're not using them.
Don't overclock.
Lower your screen brightness.
And ultimate solution, get an extended battery.
-----------
"You can overclock as much as you want, your phone will always seem too slow."
What kind of charger are you using to charge the battery? If the charger's voltage and Amp's out put is higher then what the phone can take it could be over charging your phone and charging your phone way to fast. If your charger is normal then I would invest in a new battery, a o.e.m battery is good.

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.

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.

" 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??

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.
