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

Do it this way:
Make the phone empty.
Charge it all night (8 hours + ).
While still charging, open applictaion: Terminal Emulator (it is available on the market for free)
Write:
su
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:

[Q] CM (and others?) battery meter complete screw-up

My battery never charges above ~76% when plugged in. After rebooting however, it is very much at 100% and lasts for a good amount of time. This is not necessarily a question, but I wonder if others are experiencing this too and if there is a fix? Read below.
I noticed that my battery life got very bad after installing custom roms. I also found out that this happened because I sometimes kept the phone plugged in while flashing, something that totally screws up the battery reading. So, I followed this guide to calibrate my battery and it worked.
Now, whenever the phone is plugged in it NEVER goes to 100% when charging. Maybe 80% if leaving it for a while (10 hours overnight). I'm worried about frying the battery. Is there a fix?

It is only a matter of presentation. It actually doesn't mean your batt is broken. Plug it and charge it overnight. Then discharge only for few percent and plug it back in. It should go to 100%.

Thanks, I'll give it a try.
What I'm concerned about is if the phone "thinks" the battery isn't recharged and keeps squeezing juice into it when in fact it is full (which a reboot will show)? That's not good for the battery. It should go into trickle charge after reaching 100%..

The process described in the desire forum is also known as formatting the battery. In fact most of battery manufacturers (lithium battery manufacturers) recommend doing this in a slightly different way:
Before first use:
1.) Before powering the device on, plug it in and let it charge until the LED is green (fully charged)
2.) Then take the battery out of the device and wait an hour (to make sure all the chemical processes in the battery are as idle as possible)
3.) Then plug it back in, while still off and let it charge untill green LED
4.) use the device....
You can practice this slightly modified with first step being:
Discharge the battery (by normal use)until only few percent are left (1 - 5 % are OK)
I've done these steps with my Mugen extended battery and I was getting around 4 - 5 days on Legend, now I'm getting 2 - 3 days on Desire S, but the ROM isn't very optimized yet, I believe it will be better in time...

Just one thing... Why is this in Development!?

No Idea.....
can mods move this?

Definitely did not solve it but at least the battery performance is ok. It just stays at 78% for a few hours drops from there. Very weird but as long as the battery doesn't get broken I guess it's ok.

Do you have some 3rd party battery installed in your Legend? I have one 1,5 Ah in mine and it is acting the same way. It doesn't bother me too much coz it was cheap... it lasts 48 hrs with data always on and moderate usage. I noticed this that when I charge it overnight and it reaches 80%, unplugging it stays at 80% for several hrs and just after it starts dropping if I plug it again, meter reaches 100%. It's weird but as I said I can live with that

I've got exactly the same issue with stock 2.2 ROM. I've never rooted or CM my phone; I was wondering if CM would do it, but doesn't look like it.
android forums /htc-legend/265545-battery-doesnt-fully-charge.html
(sorry, I can't post links; maybe an admin can fix the link for me?
This seems to indicate it's a phone hardware fault and requires a new Legend to fix! My big worry is, as stated, that the charging light never goes green; therefore is pumping lots of power into a potentially full battery.

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

cant find it on google again ;-( but i explain it to you!
1.Charge your phone to 100% when it is on
2.turn phone off and charge again to 100%
3.unplug on 100% and plug in again (phone is still off)
repeat this prozess 4-6 times (to get your battery more charged)
4.reboot phone and charge again to 100% till your get ful battery message
5.unplug and plug in fast till you get again 100% and battery ful message
6.repeat this till the message of 100% comes fast (should not take longer then 20sec) then your are ready to calibrate
7.open battery calibration from the market and hit calibration button
8.unplug phone (done, almost ;-))
9.let your phone unload till 0% and till it turns self off (dont charge between or connect to pc)
10.charge to 100% again without break between (this is importand then the app will write new battery history)
11.on 100% unplug and your are done!!
sounds like stress i know but this method is realy effective to get more power in your battery! specialy after flashing some custom roms!
notice: cm does not have full battery message like emanoNv4!!
i explained how to make it with cm on next page ;-)

no arent! this method is to get a more charged battery before calibration
and by the way app anyway wipes your old stats!!
wipe on cwm means only delet your old stats not get a more charged battery!!

I'm using squadzone's CM7 v5.4 ,It was at 100% already for almost an hour.
I even tried unplug and plug in the charger.
Restarting the phone and charge again and still never see the "Full Battery" message.
When its off I just see the Battery and the running dots underneath but not sure if it was already full.
Battery Status shows "Charging (AC)" with the Battery Level 100%.

ok that cm not have this full message, skip step 5.+6. and make it of time!
if you reboot after step 4. plug in again and wait like 5min repeat that 3times
and the effect is the same only without message! then make step 7. till 11. and
your are done on cm!!

I reached the conclusion that all these calibrations techniques are just a myth.
A Google engineer already stated that the wipe battery stats simply does nothing in terms of calibration. It just removes the data that shows in the battery info (chart and usage by app/hardware). Guess what? That same file is the one that gets reset after reaching 100% and unplugging the phone.
Then no calibration technique explains why on many junky Samsung phones after a phone reboot, no matter if the phone is fully charged or not, the battery loses 5-6% of battery. One reboots the phone to reset it and save battery and instead s/he gets a battery drop. I just find this unacceptable. For much less the iPhone has been massacred all over the news.

it's simply because booting os consumes energy. it have to load everything, hence the drop...

Click to expand...

Really? So why does it happen even if the phone is charging? Why it doesn't always happen? Why few times the percent even raises?? Why do I get up to 10% drops after a long deep sleep? But I don't get the same drops if turned into airplane mode (well, testing it just now)?
And regarding the energy consumed while booting, it is just a matter of having the CPU at 100% with the highest frequency for a couple of minutes. That barely justifies a 5-6% drop. Antutu battery test drops 27% every hour, less than 1% every 2 minutes. I don't see why the boot should consume much much more energy.

Honestly, it doesn't bother me that much. It was like that in stock rom, it's the same in custom roms, so I assume it's androids normal behavior. Phone's working, battery lasts for nearly 2, sometimes 3 days, so I can't complain about it

Well, in that case you're right not to complain. If my phone reaches 30 hours I must consider myself lucky. And that is with a (2430mAh declared, probably 1700mAh for real) Gold battery. But I don't have Mini/Pop I have a Mini/Pop Plus (actually Next Turbo in Italy), the S5570I.

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
