Hello I was wondering if anyone has a guide or something special for the lg revolution on how to calibrate the battery.
Thanks

Another thing you could do is if the phone has CWM on it you can wipe battery stats from there. Just have the phone at 100% then let it die completely and charge back to full charge without interrupting the charge cycle.
i have the charge and this is what i use im not sure if it will help the revo but i dont see why not, its nothing phone specific as long as you can get to recovery
almost forgot to cover my butt. i didnt make this or come up with it. just use it to make my day last longer lol. hope it helps

So yesterday I calibrated my battery and was suprised it actually worked. But today I flashed a new rom (for like the 6th time this week, I think I have a problem) Should I calibrate again?

I /think/ it's only when you flash a rom without a fully charged battery.

Well if you have tons of time I don't see why not. Most of the time, I feel that it is not necessary to calibrate the battery. I only do it when there is a severe battery drain.

+1 to this. Please ensure u flash a ROM after u charge the battery to 100%.
I've been looking but have yet to find directions on how to calibrate a battery. Can some one please tell me the ways to do this?

Charge the phone till 100% while it is turned on, disconnect the cable.
Turn it off and charge it till it's 100%, disconnect cable.
Turn it on and off, charge till it's 100% and disconnect the cable.
Now, delete battery stats using CWM or run the following command using ADB or Terminal Emulator:
Code:
su
rm /data/system/batterystats.bin
Sorry but what is cwm?

Can I flash a new ROM with 60 percent battery? I see where most ROM'S recommend flashing with a full battery. Does this affect anything like how much charge the phone thinks the battery has? Or are there other reasons to flash with a full battery?

It doesn't matter. I flashed at 5% once. The only thing you have to do is recalibrate your battery after.

That would be a big problem
I tend to always flash at 100%. Just to avoid any issues. But you can flash at 60% if you really wanted to. Just do a calibration
Do it with full battery . Calibrating takes ages

If you are using odin, by definition the phone is plugged in to a USB power source. I suspect you couldn't drain the battery in that circumstance - maybe if you were plugged in, playing a video while serving up Mobile AP. But not when the screen is doing nothing but saying it's in download mode.
I have flashed through cwm with under 50%

That's assuming every one uses odin
I just clear data and cache and flash the new rom. But I charge up to 100% so the battery reads fine.

Yeah thats why I said "somehow". I thought about your point while posting though and it makes plenty of sense and im pretty sure you can charge a phone no matter what state it is in (soft brick, hard brick, waterlogged ha)
Sent from my SAMSUNG-SGH-I897 using XDA App
Yea
I've flashed in the range of 50 - 100%, never had a problem
like others said you just have to recalibrate your battery after.
I probably wouldn't go less than 50% though just to be safe.
It would probably be best to flash on a full battery, but I don't think its necessary. Just recalibrate and wipe battery stats and you should be fine.
Yes you can. May need to calibrate
Sent from my Captivate using XDA Premium App
Anybody that has used this app.. I charged to 100%, clicked on Calibrate, then unplugged. But at about 50% battery an app caused my phone to freeze and couldn't even power+up+down reset. I pulled the battery. Do I have to start over with the calibration? There isn't any indicator on the Battery Calibrator app.
I don't think so
Just read that all these programs do is delete a batterystat file somewhere and Android will rewrite it at times. Thx.

You can clear the battery stat logs in CWR too.

Think you guys are talking about he same thing. If what I read about Battery Calibrator is correct then I guess I could just go to CWM and clear the battery stats. Good Call!!!

Is it better to clear them when the battery is dead or fully charged? Or does it matter?

You should only do it when fully charged. Charge your phone to 100% then leave it plugged in for another 20 minutes, till it's at around 4200mV. Delete batterystats.bin and it will be replaced during reboot.
Edit: the issue is that your battery will drain in cwm even while plugged in. Battery Calibrate does the same thing only without having to go into cwm.

Is it needed to recalibrate the battery each time you flash a new rom?
Does it increase battery life?

Would it work to just copy the battery stats file to another rom so u don't have to re calibrate everytime u install one or would that be a bad idea

You don't need to calibrate, just charge it full. Battery stats are automatically wiped when you unplug with a full charge.

It shouldn't affect battery. I've tested it myself, battery life before and after calibration is no different. This calibration myth was debunked by a google framework engineer.
Sent from my XT860 using xda premium
ya I read a short thing on that. Kinda odd though. Seems like sometimes u could get a worse battery life some days compared to others. But it also seems like a good idea since u don't have to calibrate every time u do something.
Sent from my DROID3 using XDA App
The calibration has nothing to do with the battery life, it just gives a more "exact" reading of the battery level.. I miscalibrated my battery once, and it was at 1% for about 3 hours, then finally died..

Ya that happened to me once. Now I just make a point of being able to fully charge anytime I flash a rom.

I have now been convinced that there is no reason to calibrate your battery at anytime. Google engineer pretty much put it to rest and since then I have flashed repeatedly and all that changes is the ROM , sometimes battery is bad and other times its great. CM9 is best so far. Until we get new kernals our battery won't ever be great.

Ya reading through the comments it seems batterystats.bin has nothing to do with the displayed battery level, but rather just what is using the battery. The displayed battery level comes from kernel level

Same, although not for 3 hours but 15min heavy load (720p mkv). Which normally kills 10% battery.
After calibrate it never happened again and died right after 1%
My battery has been sluggish right after updating 4.0.4. Right after restarting my device, i left only 20% of battery instead of 90% before restarting. Im getting sick n tired of samsung. Thers always a problem after software update. Im wondering wether they ever tested their software before releasing it to consumer. LOUSY

Calibrate your battery.
Let it empty untill blackout. Take out battery for 2 min then put it back again, and charge it to full, do not push the on button while charging.
My suggestion is to install and SPYCPU podesiš processor clock so you would not spend the battery more than they need. We also have a large selection governo, naćićeš best balance of performance and battery life.
Thanks jonpaslim! i will try to do that and will update the results

So far i hv been using pretty alot of apps. Been using carat,netqin and cpu spy. Well the batt is still i would say average.. Im wondering how to read this thing on cpu spy. Especially the deep sleep graph. Is it sufficient? Or am i doing the wrong thing or what?

You can check version in settings, then about phone in bottom Guess you are on stock. Be carefull wiping, factory resetting and deleting large files as kernel can trigger a bug in emmc chip, corrupting partitions.
good you started analysing root causes. Always best case.
now if you dont care for warrantee you can follow directions from this post http://forum.xda-developers.com/showthread.php?p=29139461 to get back to starting point of install. Or to install the awesome speedmod kernel.
Alteratively you can add apps one by one and together with battery usage analysed you can fin culprits. With tools like betterbatterystats, cpu spy and badassbattery monitor

Hi xfox,
Done with calibrating as in let it empty, take out the batt for a while then turn it on again. It seems okay for now. Is there any other way instead? Im sorry for asking this stupid question again and again. And thank to all of ya for replying my so called newby question. Lol.

How i wish i could use those speedmod kernel and so on. Well im quite afraid to root it cuz im not too sure that im gonna use this phone for a long time. As the phone value will decrease if i void the warranty. But thx for replying my post tho. As for now im still monitoring my batt behaviour.

Galaxy Note problem
When I got my Galaxy Note, the battery used to last for 10 hrs on GB. After upgrading to ICS, that time dropped to 8 hrs. And after ICS updates, it went down to less than 4 hrs since it was discharging much fatser than charging, and it was the same whether I used the original power charger or direct USB cable.
The original charger is an adapter + USB cable.
Everything went fine when i changed the USB and used the one originally used to charge the Sony 3D glasses.
Now it's charging normally and the discharge rate is around 8% /hr with WIFI and mobile data ON.
Hope it will work for you.
