It depends what type... I know one where you'd almost have to drain it but not all the way then fully charge it would make the battery life longer than having its life cut short.....

Try this technique which I used on SE XPERIA X10:
Charged the phone to 100% and while still plugged to the charger remove the battery wait 5 seconds put the battery back unplug the phone switch it back on and plug back into the charger. Ur battery should now show 88% charge not 100%. will wipe the battery stats as well when I will fully charge to see if it makes a difference.
Need to fully discharge the battery at least once a month until the phone off .. then you load up to 100%, and doing what was said above, remove the battery, and turns the charge again for up to 100%

WTF?¿??why are you opened a repeated thread? if in this section there is an entire thread for talk about it..

In spite of reading a bit one sees immediately
A simpler way is just to use Battery Calibration app, it can be found on the market.
Is it a bad thing to charge the battery at 50% still?

wow is what i am interested , the method above i have tried but no obvious difference. so the app is really that helpful ? have you ever tried it ? i don't want to install then uninstall.
There has been much confusion and frustration surrounding our battery life and these custom roms. Some of us have great battery while others are having horrid problems.
I am writing this guide in the hopes it will help all of you with problems getting that great battery life.
This is a guide written from my own experience and technical understanding.
First, Your phone should drain, on average, 1% per hour or less while in standby mode (screen off). If you are not getting this average, you need to calibrate your battery.
ALWAYS flash a new rom with your phone at 100% battery - no exceptions!
i know some guides say to run battery down to 2% and then charge, but i never had much luck with this.
1) Before you flash your rom, charge your battery to 100% with the phone ON.
2) Once it says fully charged, turn the phone off and plug it in and wait for the on screen display to say 100% (this will take 5 to 10 min)
3) Turn the phone back on, and plug it in and charge till it says 100%
4) turn off the phone and charge again while off until the on screen battery indicator says 100% (again this will take 5 to 10 min)
5) repeat steps 1 thru 4 as many times as you feel comfortable, I recommend at least twice (I do it 3 times)
6) when you are satisfied with the charge, and the phone is still OFF with the indicator saying 100%, unplug the phone, remove the battery, and place the phone in download mode (hold vol down and plug into the PC)
7) flash your package (this is done in odin with the battery removed)
8) The first boot after the flash needs to be into Clockwork Recovery, wipe battery stats at this time (most roms will boot into recovery automatically, if not, boot into recovery manually)
9) after you have wiped your battery stats, wipe cache and other data (if the rom you are flashing requires this, if not, skip this step)
10) Boot the rom to the homescreen.
11) from this point on, you will use your phone like normal until the phone completely shuts off. this SHOULD take a while. you should see improved battery life during this stage. If not, dont panic, just run the battery down until the phone shuts off
12) once the phone shuts off (try to time this to happen at bedtime) plug the phone in and allow it to charge in the OFF position
13) once it is at 100% again, use the phone like normal and enjoy your new battery life.
IF YOU ARE DOING THIS WHILE NOT FLASHING A NEW ROM
Do steps 1-4 as many times as needed, I recommend at least twice, i do this 3 times
on the last charge up (your phone should be off while charging during this step) unplug the phone and boot directly into recovery and wipe battery stats. then proceed with the rest of the guide.
TO TEST THIS
charge to phone to 100%, try not to mess with it for an hour or so.. (light usage at most) you should still be at 100% or 99% after an hour. If you are at 95% or below, then the calibration has failed. (unless you have been using the phone or are in a very low to no signal area).
this calibration method is crucial to good battery life. Before I started doing this i was getting very bad battery life. Click on my username and look at my previous posts.. you will read about me *****ing badly about my battery, this is what I did and it has worked amazingly well.
I hope this helps
I combined a lot of techniques ive seen in other threads and some websites and then created this technique which seems to work really well.
I have used this technique and can confirm, it works well if done properly.

Are the first few steps what is referred to as "bump charging"?
I think this has worked quite well. I flashed Humble 1.2 (at 40% battery) last night, charged up, then started this procedure. After I got done, I took it off the charger and after 15 minutes of trying a new game, listening to a minute of music, and checking various things, I was still at 100%. i left it off, went to bed with wi-fi on, and woke up at 95%. Awesome. My all-day phone is back.

What happens after the calibration process? do i have to do this everytime i charge my battery or does like normal mean i can just leave it charge whenever. Also with what frequency should i be doing this? once a month calibration?
Just did this... 1 hour 15 mins. and still at 100% Sent two text messages out and played Words with Friends for a minute. Thanks!
Did this and it didn't work advice on what I am doing wrong I did the bump charge 2 times ran the phone down 100% and am now looking at 88 percent of next to no use after about an hour and a half of having the phone on.

I am in the same boat with you.....I'll just have to accept the fact that I will have to charge every 6 hours, which was a 2 hour step up from the TB.
This works, going on 17 hours and still at 65%.

What I am curious to know is what is usage like for the people that this worked for. Don't get me wrong I'm not doubting the op but I am a pretty heavy user and even so I'm not really experiencing this awesome battery life everyone talks about when I'm not using it heavily

For all of you that are getting the great life, what percentage does it list for display? This is under settings > about phone > battery use.
I'll have to try this method. My battery life is actually worse now after I tried doing the drain to 2% method. I'll report back with my observations.
Are we talking 3G or 4G here?
I would find it useful when people are talking about how good (or bad) their battery life is to know if they are in a 4G area and have 4G turned on, or are they using 3G only?
Trying to figure out how bad a hit 4G takes on my phone...
Thanks.

So I tried this out yesterday...I don't have a rooted phone so I could not wipe battery stats (does anyone know how to do this without rooting your phone?)...but I did follow steps 1-4 three times and I have gone 23 hours on my charge without having to plug it in. I am in a 4g area and had 4g and background services on for the full 23 hours. Had bluetooth, GPS, and wifi turned off. I sent a couple texts, used whatsapp to send texts, used google voice to send texts, made 3 phone calls (about 4 to 5 min each) played angry birds for about 20 min, played words with friends for 10 min, surfed the web on and off, was on tapatalk and browsing forums for about 20 min and I installed a new keyboard and web browser on my phone in those 23 hours.
I am very curious to know if this will improve battery life after that first initial bump charge.
If you do a regular charge after depleting the charge, do you still see improved battery life?

Yes. The phone will pull the necessary power for download mode and the Odin flash from the USB port. Just be sure to use a primary USB port (usually the ones on the back of the computer), rather than a hub, as the hub tends to cause problems.
I read a lot of thread about battery calibration so I want to know if someone try this on XT720 and if it's really usefull and not dangerous for the phone.
Thank you
It is useful and not dangerous at all. Your battery has, if stock that came with phone, a full charge of 4.2v.
So let's say that you have been conservatively using you phone most of the day and are at 70%. You decide to flash the Hellmonger edition or CM6 but you make a nandroid backup first. You flash them and it goes horribly wrong and your phone power dwindles down to 30% and you freakout and charge it back up.
When it is charging, you decide to hold off on flashing for a bit and want to go back to your "home" ROM, whatever that may be. You let your phone charge up to 100% and re-flash your back up. Once it reboots and settles down, you happen to notice that just 5 mins ago you were at 100%, but now after flashing your backup, your battery shows 70%.
30% drop in 5 mins is rediculous. Yes it is, bit it didn't really drop 30% in 5 mins because when you backed up your original ROM, you also backed up your data/system/batterystats.bin that was calibrated to 70%.
If you use Battery Calibrator and charge it up fully, run app, hit it and then unplug, it deletes the data/system/batterystats.bin and in a few seconds (5 ithink) it creates a new one with you proper charge and voltz.
So if you flash a lot, this is good for you. Or you can delete the batterystats.bin manually if you want, but there's an app for that.

So, if I understand, it's not so usefull because after I lose my 30%, if I charge and I have 100% it's really 100% not 70% right ?
I would say that it is always best to start from a clean slate. It deletes that batstat file and starts anew. Can't hurt, but if you are flashing ROMs every 3rd day like most of us, it does come in handy.
For the moral of the stroy, it will not damage your phone. Just a one click app that you can do manually with Root Explorer if you wanted to.

Its recommended that the battery drain fully, and then be recharged without interruption. I guess thats to give android a full scale from full to empty, to help better report battery stats and consumption.
However for me full drain means 10-15%, its hurts the battery to be drained till the phone powers off.

I used to drain it fully till my phone turned off before calibration but I read a very detailed article about how draining the battery completely can hurt it. So I choose to drain it till 5-10% which is good enough
How come sometimes when the battery is full it shows 4200mah like it should but sometimes it shows less like around 4165mah in the battery calibration app? At 4165, I still left it there to charge to see if it would increase or not but it didn't...
Sent from my MilestoneXT720 using XDA App
I know that the last little bit of charge just trickles in and takes a long time. If mine is at somewhere between 4150 and 4200, i call it good and go from there. If it was showing at say 4095 and 100%, then there might be something wrong with either the data or the battery. If you are sitting at 4165, then it is charged for the most part.
The app and what it does is more for when you are flashing a ROM and have around 60% and then once booted up fully, you charge it up to 100%. Decided you don't like your ROM and go back to your original ROM via backup, it will show 60% instead of the 100 or 90% you had before you went back to back up b/c you backed up the batstat bin when you nandroided your original ROM.
How about this:
ROM: Epicsteelblue 70% (and you made a backup) Then went to CM6, charged and hit calibrate battery at 100%. Used CM6 for a few hours and decided it wasn't your bag. Your batter is at 50%. You flash back to your Epicbluesteel ROM and you know for a fact you had 50% before you flashed back, but now once totally booted, you are showing 70%. This is why you use the battery calibrator after you flash a ROM. Gotta create a new batstat bin for you "fresh" ROM (even though it is a backup).
Hope this helps explain better.

That happens sometimes to me aswell. The battery calibration app shows the battery full at 4165 or somewhere in that range. What I do with that is bump charge it. So if battery calibration shows 4165, i just calibrate it and turn the phone off while it is connected to the charger. When it turns off the charging screen appears and shows 100%, i leave it there for an hour or two. Then remove and turn the phone on. If you go into the battery information itll show the charge to be 4200 or close to that. Hope that was helpful you can try it next time.
EDIT: The reason I turn the phone off and let is charge is that when it reboots after fully charging to 4200 it can create a fresh battery stats. Remember battery stats are only rebuilt upon boot. If you calibrate your battery and then dont reboot its useless. To test calibrate it, and then use it for awhile and then try to recalibrate it the app will indicate that there are no battery stats avaible to delete. This is because the ROM has not made any new battery stats and will only make them on boot.
hey guys has anyone tried this method (http://forum.xda-developers.com/showpost.php?p=11803458&postcount=10) of calibrating battery? it seems the dev says that if u use his method, you can calibrate without downtime!!
wow this is damn cool. but its kinda complicated. the old way feels better for me i think...
Battery Updates
The battery updates every 10%, is there any way to make it update more precisely, like every 5%?
I've never been able to get anything better that 10% battery increments
Okay thanks maybe in a future rom this would be nice.
Hi
Is their a way to change from 10% to 1% increameants.

It is the property of all rechargetable battery, 4.2V can only see at the moment charging progress just finished. when the power management IC pull of charge current, battery's voltage will drop a litte in a very short time, like you said, 4.165V for example. And, because of your charger is connected, battery will not drain, It won't be another charging progress witch you are expecting.
I know I'm digging up an old thread here, so sorry for that. I've recently tried a few other ROMs, but since have come back to CM6.3.7. I always do the battery calibration thing when I flash ROMs and each time I've tried it lately, it gives me odd information in the Battery Usage screen. I charged my phone to 100% yesterday before leaving work and when I got to work today, it showed 70%, which seemed normal, but the Battery Usage screen showed "1h 24m since last unplugged" and I know I hadn't plugged it into the wall or USB for about 12 hours. I did restart once....could that be the reason why the time since last unplugged is incorrect?
I'm trying to calibrate my NS (i9020T) because it seems like battery drains quite fast after frequent flashing ROMs. Last time I calibrated was about 4 months ago.
But the problem is that it won't charge beyond 99%. It used to charge up to 100% before if I leave the screen on.
But don't I need to get battery % to 100% (that's what calibration app says)..?
How can I get it back to 100% charge?
Thanks!

Not sure if it works ffor ns, but drain your battery, go to data/system and delete batterystat or something along those lines and reboot. Let it charge for awhile and it should go to 100% . If it works you don't need to calibrate anymore as that's how normal apps calibrate.

drain your battery, delete the batterystats.bin, reboot, then charge all the way. chances are is that you had to wait a bit longer for it to hit 100%. when i charge my phone to 100, sometimes it takes an hour to go from 99 to 100%. be patient, if that 1% is worth it. the more you play with your phone between 99 and 100%, the longer it will take.

I waited 5 hours but it was still at 99%. I had to leave home so I couldn't charge any longer...
So drain it first, delete batterystats.bin, and it should charge to 100%? Because the app I downloaded says, charge it to 100% then delete batterystats.bin.. etc.

you must had something running in the background. believe me, the different between 99 and 100 is almost non-existant
The last 10-20% trickles in. 5hours is way too long though. What does your voltz read bc you can have a full charge as far as voltz go but may be getting a faulty % reading on the charge.
If you use the apk make sure you don't power off or you will regenerate the battstat through normal process and then the app is pointless. Try charging overnight and see if you can get to 100%.
Fyi/beware draining your battery to 0 is not good. Some batteries and phones have a hard time getting through first boot when there is little to no charge in the battery. Whenever I use the calibration apk, I never go below 10%. Anything below that can cause some funk.
I drained it all the way and deleted batterystats.bin, charged it all the way back overnight, but it doesn't go over 99% for many hours. I stopped all the services I could possible (kept only the essentials)...
Current Charge: 99%
Voltage: 4.176 mV

So it's simply misinterpretation of the battery that it doesn't read 100%?
Well, I started calibrating about an hour ago. I thought it shouldn't matter too much.

Yes your phone sometimes gets out of sync with its self and starts thinking that its fully charged or fully discharged when its not. The way I typically calibrate my battery is to turn it off and let it charge until it stops (this is easy to see since the screen lights up and the battery shown on the screen stops unfilling and refilling). I then unplug it and boot it up. Again, shut it down and plug it in and let it charge until it thinks its full. Again, turn it on this time letting it charge to what it thinks is full while on. Finally restart into CWM and use its too for wiping battery stats. After all that I also like to let it die before I plug it in again.

Naturally drained? Regular use is needed to drain the battery. An unused battery (I have a couple) will take months to drain. Just use the phone as you do in your every day usage. Let it get down to about 5 to 10% then fully charge and calibrate.
you cant calibrate a lithium ion battery. in fact draining them is bad for the battery. however if youre having problems with the phone not reading the battery percentage correctly you need to wipe the batterystats.bin using either clockworkrecovery or just download the battery calibration app from the market.

Really? Cycling the battery a few times for better performance is a myth?

yes for lithium battery it is. the older ni-cd batteries required this.

infact..this result shows that you should charge often. 10-15% discharge..and charge cycles provided the longest battery life.
this article is very very good!
That's good information. While I didn't know all that I did find the whole calibration idea a waste of effort. I've tried calibrating the battery on a couple phones and my battery life has never increased. The most that ever happens is I'll find myself away from home with no charger and have to quit playing with phone so I have enough juice left in case of an emergency.

No, Lithium-ion batteries do not have a memory effect.
Technically, you are not calibrating the battery, you are calibrating your phone's battery gauge. The easiest way to do that is with the Battery Calibration app.
1. Open the Battery Calibration app screen. With the phone on, charge to 100%, then let the phone continue charging for another 15 min.
2. Press the "Calibrate Battery" button on the app (deletes batterystats.bin), Close Battery Calibration app then TURN THE PHONE OFF IMMEDIATELY!
3. Disconnect AC charger
4. Remove battery
5. Wait 30 seconds, then re-insert battery
6. Charge phone with phone off for half an hour
This tops off the charge on the battery.
7. Disconnect charger and turn phone on
As the phone turns on it will create a new batterystats.bin and record the high battery voltage as 100% battery.
8. Use the phone normally and run it down to 0% when the phone shuts off.
The phone now knows the curve of this battery as it relates to your phone's ROM
9. Charge the phone for ten minutes, then turn the phone on and let it continue charging to 100%
This lets batterystats.bin know your phone's charging curve
10. At 100%, remove charger
Now use the phone normally. You will be happy to get an extra few hours use of your phone.
If you really want to get the most out of your battery, get the Battery Monitor Widget Pro app. It keeps a close watch on your battery and also allows you to change batterystats.bin files for different batteries.
And always remember to Give Thanks if you find this helpful!

out of all battery calliberation posts ive seen till now but this one makes complete sense. this even gave me an idea how this "caliberation " works.
again, thanks
