Calibrate my battery

Which is the best style to calibrate my battery? I't only lasts for 10h.

10 hrs is pretty good
i only get 4 hours under heavy use

I forget which thread it was but it said to completely discharge until the phone switches off (ignore please plug in prompts) and completely charge it back up 5 times. It worked wonders on mine
4 hours? pah, i can kill mine in under an hour lol
seriously though, it all depends on usage and how much you have running on the phone (big widgets and social feeds for instance), screen brightness also has a big impact.
On average i get a day out of mine but my mums boyfriend, with the same phone uses it far less and has had 3 days from his on one charge

Ok i'll try your method. Thanks guys!

I have mine going down to 79% within half a day,only standby and frequent switching on of the screen, is it normal? Thanks!

So you mean discharge completely and recharge completely and repeat this 5 times?
What about the following method :

Just wanted to share that I got an improvement
after recalibrating the batery,
Basically just charge full with phone on
then turn off, charge, turn on, turn off, charge.
I advice this for those who have flashed the firmware..

So which one of these two methods is the right way to do it?
EDIT: And how good is this guide?
1. Run the device down until it turns itself off.
2. Turn it back on and wait for it to turn itself off again.
3. Remove the battery for 10 seconds.
4. Replace the battery, but leave the device off.
5. Charge the device until full and then for another hour.
6. Boot into recovery and reset battery stats (or, go to console and type “su” enter, followed by “rm /data/system/batterystats.bin”)
7. Run the device’s battery down until it turns itself off.
8. Charge to full while off.
9. Restart and use as normal.

IMHO, the battery stat is just pure witch doctor style..
Id recommend you use the phone till it drops down the 2% then power it off and charge it while its off.. that way it MAY take upto 4-5hrs charging when it says its full remove the battery for 1-2mins then install it again and charge it while unplugged its gonna charge for ~5mins and when its full disconnect the charger and power on the phone.. you just need to do this once ( on my experience ) and charge as often as possible since its not a good idea to keep draining lithium batteries

While still charging, open applictaion: Terminal Emulator (it is available on the market for free)
Write:

rm /data/system/batterystats.bin
it looks like that nothing really happens, but it does.
Reboote the phone. Important!
You will see the difference. I get from 1 day before to 3 days now.
For doing this, your phone, of course, should be rooted.

There's another method^^
I really don't know which one of the 4 battery calibration methods that I've mentioned above I should use?

I've read from many sources to not worry about frequent discharging/charging of your battery. The lithium-ion batteries we have in our phone will degrade based on cycles (when a certain number of charge cycles have been reached). As for overcharging, the phone is smart enough to stop charging once the battery is at 100%. The battery will slowly discharge, and once it hits a certain point between 93-98% it will start charging again.
As for which method works the best...I'm struggling with the same issue. Personally I've tried almost every method other than the reset battery stat (which I plan to do as a last resort).
I have found that the battery gets better after a few weeks of use. The full discharging/charging does help marginally. The turning on and off method of charging also helps marginally. The biggest culprit is usually background apps preventing your phone from properly sleeping or activating your data when your phone is locked. I was using juice defender and my battery still drained crazy. I JUST changed my juice defender to turn on data for 2 mins every 30 mins (as opposed to 1 every 15) and it seems to have made my battery better. Before I did this, my phone drained 40% in 6-7 hours (while i was sleeping). Right now... my phone has been active for 5h48min and is at 72% (a bit of texting, a bit of 3g, and wifi). Here's hoping it'll get better.

This thread helped a lot
My phone drained 70% of battery from 5am till 12pm (while I was asleep). When I saw the battery usage stats it said that Android OS draind 68% of the battery. I flashed the phone on sunday. I should do a calibration then, right?
I'm going to try this method:

Milestone battery stats?

It seems to me, alot of people do this with their samsung devices, and htc devices...
Do any of you milestone owners do this?
If not... heres how:
Either in TERMINAL or ADB enter:
rm data/system/batterystats.bin
Click to expand...
Click to collapse
1. turn off the phone, plug it in, preferably overnight.
2. boot the phone up while still pluged in.
3. delete the batterystats.bin file ether through adb or terminal
4. drain the battery fully, untill it powers down.
5. wait a min or two and reboot it to completely drain it.
Congrats... your phone now knows correct voltage values for 100% and dead.
Remember: Flashing a new build/rom erases the battery stats, and automatically rebuilds them based on voltages it sees.
NOTE: you need to recondition after each flash to get max battery life.

trying to do what u said))
u forgot to "unplug power" to drain the battery ^_^

Does it really help? I've tried something similar, but without noticeable result! =(

seems to be working much better now. Some say they dont notice anything, but i pulled my phone off the charger around 11am today & normally im down to around 75% by this time, (6pm) but im still at 90!!!!!
So yeah im going to say that this works pretty well!

I don't know if this is any help, but during the charging stage while the phone is off, if you take the battery out, the stone will go from 100%, and then reboot, but go back into the same charging screen with a big ? in the battery.
Place the battery back in, and it will go to 60%, and continue charging until the battery reaches its top voltage, around 4150-4200mV depending on condition on the battery. I noticed that when it would jump from 100%, to 90% in only a few minutes of use, that the battery had only been charged to about 3900mV, yet it still displayed 100% and would not charge further

Touché sir!
Just did that.. since it was off/charging before i head out to work, then did the battery pull & got the ?? then down to 60%
weird... there has to be some way to FULLY obtain 100% charge, every time... ya know?

Yeah it seems to work!!!!!!! GREAT!!!
EDIT: everytime that the battery has fully charged, when I take it out and then in again, it always displays 60% and starts charging again..

figured it out...
1. do the battery pull trick
2. get to 100%, then boot-up
3. while still plugged in, sweep the battery stats
4. restart (disconnect while rebooting)
5. FULLY drain, restart to ENSURE dead-battery
6.plug it back in charge to 100%
once charged, unplug & enjoy!

You'll find that it will jump up from 60% to 100% in a few moments when the battery has reached its max mV and wont charge any longer if you keep doing this little trick.
This clearly shows that the android operating system has a flawed battery monitoring system. Although the battery pull trick works on the milestone, other devices report this same problem, and have different little 'tricks' to get the battery to charge fully.

yeah i wish we had an app like the One-Click-Lag-Fix that would do that for us, instead of us having to manually do it.
I dumped my whole system cache, plus swept the battery after gaining 100% charge. It works much better now. I use CacheCleaner Legacy to clear my system & dump the file using Terminal.

Removing the battery and reinsert again works, but just once!
Next time, when it fully charges, you have to do the trick again, because it charges just until 60%, even erasing batterystat.bin
Isn't possible to hack batterystat.bin in order to make it charge completely?

Method to improve battery life

Hey guys I just picked up the Thrill the other day, and like others I've realized the battery life is horrible on this phone not to mention when I reboot the phone would take a 10-15% out of the battery. Coming from an Atrix I decided to try the battery fix for the Atrix since it worked for me in the past, well after following all the steps in the guide it seems my phone reports the battery more accurate and battery life is better but your mileage will vary. Reboot doesn't take 10-15% out of the batter percentage either so here is the guide and link to the original thread, all credits go to xploited.
PS.. I followed all the steps except for flashing the jug6ernaut's CWM battery fix since it is for gingerbread roms
Link:http://forum.xda-developers.com/showthread.php?t=1198333
Guide:
Standart disclaimer: I am not responsible if you break things by following this guide, though I will be genuinely surprised if you do.
Credits: This fix is a combination of battery management techniques discussed in the Atrix forums + a technique that I originally found in a Milestone forum (I didn't invent it, but I am too lazy to search who originally posted it ).
This worked in fixing the problem for me (the same problem that I see many others are writing about on the forums), but I can't guarantee it will work for you.
Who should use this? (aka your battery problem symptoms are
1. Battery life on 2.3.4 is significantly worse for you than before.
2. Battery stats are jumping and showing inconsistent information.
3. Your phone loses 30%-60% just by sitting there overnight.
4. Phone idle draining 30%-60% of battery just by sitting there overnight.
5. After flashing a couple of roms, your battery stats got messed up and the phone thinks it's at 100% charge while it's not.
I personally started having battery problems after flashing a couple of roms, applying 1% battery mod and despite flashing jug6ernaut's CWM battery fix.
When I went to bed with a 100% charge, I would wake up to a 50% charge, with Phone Idle process showing up as massacring the battery. The steps below successfully fixed the problem for me.
Prerequisites:
1. Atrix on one of the rooted 2.3.4 roms (ideally,- deodexed and with unlocked CWM)
2. Wall Charger
3. jug6ernaut's CWM battery fix (put it on your SD card you will need it later!) I have also attached it to this post.
4. Battery Calibration app from the market
5. Watchdog Lite or Full from the market
Instructions:
It's best to complete this procedure in the evening before going to bed, so you can leave it at 100% overnight and check in the morning if the drainage issue is fixed!!!
The whole procedure along with recalibration might take up to 5-6 hours!
1. Take the case off your Atrix (one of the latter steps involves taking the battery out from the phone while it's plugged in. Make sure your case won't stand in the way.)
2. Install Battery Calibration app from the market
3. Plug in your Atrix to charge while it's on, wait till it gets to a 100%
4. When the charge is 100%, open the BatteryCalibration app and lookup what the charge is in MV while at 100%. (Explanatory pic, needed number circled in red). Write it down.
My Atrix was showing ~3400MV while at 100%, which is definitely not the maximum capacity.
5. Discharge your Atrix completely until it shuts off.
A good way of doing this quickly is by turning on wifi, and a video player.
6. Without turning on the phone plug it into a wall charger and let it get to 100%
7. When it's at 100%, without unplugging it from the wall charger, take off the battery cover, and take the battery out.
Your phone will "reboot" and show a Missing Battery icon.
8. Without unplugging the phone from the wall charger or turning it on, put the battery back in and wait until the phone recognizes the battery.
9. Your battery should now be recognized by the phone, and showing a charge % significantly lower than 100%.
Mine showed only 5%. Back when I used a Milestone, it usually showed 60% after doing this.
10. Let it sit there charging for 2-3 hours.
My phone wouldn't charge past 10%, but yours might. The numbers don't matter much as the phone is definitely getting additional charge that could have been lost while flashing ROMs, etc.
11. After 2-3 hours, turn the phone on while holding the volume down button and get into CWM.
Do not disconnect it from the charger still!
12. Install jug6ernaut's CWM battery fix (even if you had it installed before), do not reboot yet.
Do not disconnect it from the charger still!
13. Wipe battery stats in CWM, reboot.
Do not disconnect it from the charger still!
14. When the phone turns on, go into BatteryCalibration app again and look up your MV numbers
- if you were like me, they should be significantly higher than before. After this whole process I had 4200MV at 100%, comparing to 3400MV before calibration.
Do not disconnect it from the charger still!
15. Before going to sleep - Install Watchdog from the market. Go into it's preferences, set CPU threshhold to 20%, check "Include phone processes", check "Monitor phone processes", check "Display all phone processes", set system CPU threshhold to 20% as well.
Do not disconnect it from the charger still!
16. Make sure your wifi and data connections are off. Now finally unplug the phone from the charger.
Go to bed, let your phone sleep too.
17. Success! Next morning check where your battery % is at and if you followed the instructions correctly / got lucky like me, your battery life should be 90% or more.
I went to bed with 98% and woke up to 94%. So, I consider this mission a success.
(Your general battery capacity should have increased, even if something still was draining the battery, you will be able to find the infringing process in WatchDog with the settings we've set up in step 15 )
Click to expand...
Click to collapse

Not a bad process. I did something similar. Main part is Watchdog and finding out what's draining your battery. On my phone the infringing process is "Suspend". Now, if there were an app that was keeping my phone from suspending and running up the process it would be an easy fix but unfortunately the process with the highest "partial wake" battling my "Suspend" is the "dialer" so unfortunate I'm just gonna have to wait for GB since I have no interest in Rooting or installing roms at this point.

I'll give this a go. Thank you

Consistently Incorrect Battery Percentage

Hey all,
I have had terrible misfortune in the realm of battery stats. Ever since CM7 (and maybe even before) my phone is unable to figure out how much battery is left. Here is a common scenario:
Charge phone overnight, use phone throughout day, battery dies after 6-7 hours of moderate-heavy usage. I plug it in, reboot, and then it reports ~60% battery left.
Another common scenario is that it will dwindle around 5% battery or less and go up and down until it finally dies.
I know that this is a misreading of the battery and not battery drain or a rogue app because when I flash a new ROM the battery life is amazing for 1 day. The day after I flashed Team Hacksung's ICS rom, I got almost 17 hours of battery life with 2.75 hours of the display being on and 30 minutes of Google Music. I was blown away! But even then it was dwindling around 5% not knowing when it would actually run out. The day after, it was back to its old tricks of misreporting the battery percentage.
Today I charged it to 100%, unplugged it, and shut it off. Then I plugged it in while it was off and let it charge to 100% again and wiped battery stats in Clockwork mod. I'm getting ok-ish battery with that, but it's not even close to how good it was when I first flashed ICS.
Anyone have any ideas what I could try?
Thanks!

When you wiped the battery stats did you let the battery fully discharge and shut off before charging again?
After wiping battery stats it is recommended to let the phone fully discharge to the point where it will automatically shut off.

Keep in mind with the age of our phones, it could just mean your battery is dying. Try the above method, but in my experience uncalibrated battery only last a few days. The phone will "fix" it by itself the longer you use it.

That's what I'm doing currently. Battery life seems improved, but we'll see what happens. It's nearing death now, ~6%. At this point it will probably misreport it for a few hours until it finally dies. I left it unplugged overnight, so now it's at 19.5 hours uptime with 1.75 hours display time.
Definitely improving! I hope that it successfully recalibrates.

Battery stats have nothing to do with how the os calculates remaining battery...they are what is displayed in settings>about phone> battery use and are reset each time you charge to full.
You're just giving it a good bump charge...wiping the stats is just a placebo effect.

Seriously? Wow I didn't know that. Is there a way to actually reset how the OS calculates the battery?
Does this app do anything?
https://market.android.com/details?...xLDEsImNvbS5uZW1hLmJhdHRlcnljYWxpYnJhdGlvbiJd

Nope...that app is just perpetuating the myth of what the batterystats.bin file does.

Don't hate me for this but, Then how come Roms usually give me better battery life after a full cycle? not bump charging or deleting battery.bin just running it?

Because the system for tracking the remaining power is getting to know your battery. once it gets a feel for it, it's more accurate. In theory anyway

So the "give it a day" is still true, at least in theory?

battery gauge temporarily fixed by removal and replacement of battery
Ever since I rooted my phone, I've noticed that the battery gauge/meter is way off. I keep an eye on the charging voltage and try to pull the plug around 3.92 volts. Problem is, the gauge is always reading low until I pull the battery, wait a few minutes, and then reinsert and boot up. Then it's fine for a while, but I notice it creeping down even though I keep topping it off with a charge to keep it around 3.92 volts.
What's going on? Do I have to fully deplete the battery and charge to full to have an accurate (or somewhat accurate) battery gauge? Do I have a bad battery (this battery has been used only a couple months)? Is something else going on here? Recommendations, studacris? Doesn't the os use battery voltage to calculate state of charge (%)?

Huge problems with my galaxy s3 in the past few days.

Hello everyone!
This is my second post here...but I really felt like I had to take attitude this time and actually do something.
So my samsung galaxy s3 is acting so weird that I can't use it without something bad happening for one day.
So...first of all...my battery doesn't last more than four hours straight if, for example, I am listening to music.
It literally goes down about 1% every few minutes.
Also..there is something really weird happening with my battery even after it completely shuts down. Lets's say I am on 1% and the phone shuts off. After the screen goes black and I plug it in...the charging screen appears and the battery seems to be half charged. I open the phone again and it is already at 45%. All this operation takes a matter of seconds...but still it goes from 1% to 45%. After the phone is up...this percentage starts to go down even faster than before...in the end my phone shuts down again...and this time it starts to charge from 0%.
Today it shut off...and when I got home and plugged in the charger it didn't do anything...i just left it like that for about 10 minutes then tried to power it on without the charger being plugged in...and it worked. After that it started to charge. I have no ideea what is happening.
Also...my charging time is really big. I do not know why but when I use another charger from a samsung galaxy mini 2 it seems to charge way faster.
That's pretty much all so far. If you need more details, please let me know.
I hope you can help me sort this out!
Best regards!

1.Might be the battery is dead or broken, or its not calibrated. How old is the phone and battery?
2. It seems to take ages to charge my s3 lte too, give us a number in hours how much time you need?
3. The problem where phone wont turn on or show charging when battery is as low as 1%, i had this too, i think its normal, its protecting the battery
4. Do you have overcloacked anything? It happend to me when i had ovecloaced and did benchamark test, the phone froze and battery eas 5% when i restarted the phone, but before it was 45.
Not realy helpful but i am trying XD. Also might wanna buy new battery, its not that expesive

if you are running stock rom with no rooting no anything....100% it's the battery.
if not install stock and see how it goes...if it's acting normal then the mods are the problem...if it's the same it's the battery.

Do a factory data reset on stock recovery. See how that works out first

Starting from factory reset is bad idea - it should be the last step IMHO.
First what in such case we need to check is battery health.
Percentage we see on our phone is weak indicator, because it is calculated
Better to see the voltage in different situations. How to check this (terminal app or adb in console):
cat /sys/class/power_supply/battery/voltage_now
The lowest voltage that device can handle without heavy usage is less than 3500mV (I saw even 3240mV, but with low brightness, no data connection and after trying to make a call phone turned off).
The maximum voltage is obout 4300mV.
When You see 1% of battery and voltage is realy close to 3500mV or battery is charged and voltage after removing charge is dropping realy fast to then your battery very likely need to be replaced.
I bought Samsung Extended Battery (3000mAh) and this tripled the time usage than my 2 years old normal battery 2100mAh. You can see that difference in their capacity is much smaller - about 43% biger, but give me 300% much time on battery so old one was realy worn out.
BUT if your battery wasnt used for longer than half year, you can do as follows:
1. Discharge battery
2. When phone turns off - turn it on again, but into download mode (Home-VolumeDown-Power)
3. Leave phone for as long as it turns off again and repeat step 2 till time that Download Mode wont even boot.
4. Take off battery and place it back, and again try point 2 (start Download Mode) - do it until phone will show Download Mode for only 2-3 secconds
5. Again and last time replace battery and charge phone, but turned off
6. When phone will be charged, turn it on and leave it on charger for about one hour
After those steps use your phone lightly and try to repeat whole process one more time but only when the battery will normaly discharge and phone will turn off.
I tried those steps and battery for sure can work longer FOR ONE RUN, but unfortunately it can lead to loss of capacity much faster, but it will be noticable after one year - IMHO its always good time to buy new battery.

Nothing good will come from that procedure. Those steps were useful in the epoch of nickel-cadmium batteries, where the battery had no internal circuits to monitor itself and had a tendecy to uncalibrate. Those stops would force the device and the battery to re-adapt to one another.
But now we're using Li-Ion batteries, and those DO NOT like to be fully discharged. Hell, the device might not even recognize the battery, if it has really been fully discharged.

Okay...so I went to the shop from where I bought my s3 (Orange shop) And they told me to send it to their service and I did so...as I still had it under warranty. It was there for exactly a week and today I got it back. They told me they replaced the battery (which they actually did...I checked that) and the power connector from my phone. The battery it's still not good enaugh in my opinion. Immediately after I got it back...I turned it on and it had 79% battery. In about an hour it went down about 25% (so to 54%) but I didn't used it havely (note: the mobile data option was on). I really do not know what to do. I asked someone and they told me to send it again because this is not normal.
My s3 is running stock 4.3 and used to last waay longer back in the day.
What should I do? I literally got about max 5 hours of use before I sent it and I am afraid this will happen again. I do not even want to think what is going to happen if I listen to music for example.
I turned the phone off a few hours ago...then let it charge up to 59% and then stopped because I had to leave. I used it moderately for about 4 hours and 51 minutes (as my phone says) and i have about 2h and 15minutes of screen on time. My screen is using 50% of the battery and also Android system is using about 17%...chrome 12% Android OS 7% and I think everything else is less important as they use 7%<. After those almost 5 hours...while the mobile data option was on all the time I am at 14% battery.
What do you think? Is it good enaugh? Should I send it back? I really need help!
I am waiting for suggestions.
Best regards!

I think so, the fact that you have the screen on top of Android OS (and not the other way around) pleases me. You had your screen on for 2h15m, of course your battery went down fast
Test it, charge it full, and use it. Normally.
Do this for 2 or 3 days, and check how the battery lasts
