A while back there was a thread about supposedly calibrating X10's battery by charging it to 100%, turning it off, taking the battery out and inserting the charger chord, and then putting the battery back. This made the battery percentage drop down to 88% and when repeating this procedure a couple of times it would rise back to 100%, thus supposedly calibrating the battery. This worked to some and to others not. Now that we have xRecovery, I thought I'd try this in conjuction with the battery stats wipe option and whaddayaknow, I've got better battery life now. Now I can go through a whole day with heavy usage and still have some battery left for the phone to survive through night with data and syncing on. So I thought I'd share this with you guys to try out and report too.
ROOT IS REQUIRED!
STEPS:
1. Download and install xRecovery from here.
2. Charge your phone to 100%
3. Turn off the phone and boot into recovery
4. In recovery, go to Advanced options --> Wipe Battery Stats --> Yes
5. Take the battery off
6. Insert the charger chord
7. Put the battery back and wait for the phone to boot
8. Once the phone boots up, you will notice that the battery percentage is around 88% instead of 100%
9. Charge the phone back to 100%
10. Repeat 4-5 times, seems to be the sweet spot
11. Enjoy your hopefully better battery life and report!
REMEMBER THAT I'M NOT RESPONSIBLE IF YOUR PHONE BLOWS UP ETC. AFTER THIS!
Do i need to repeat all from 1 to 10 until i get 100? And do i need to do this 1 Time or do i need to do this the next 2-3 Days too?

Repeat from step 2 onwards till step 9. I believe you don't have to do it more than two or three times to get the desired effect, that's why I'd like to have you guys to test it out too to confirm.
Been through the cycle 5 times, still showing 87% at reboot.
Just for the record, I have the 435 firmware.

Yes my friend, followed to the letter.
I have noticed one thing, my battery is behaving a bit strange. I used it earlier and it depleted from 100 to 93%, it then went back in my pocket for an hour or so and when I next used it it said 98% charge.
I ran it down to 83% and then put it back to sleep for 30 minutes, checked it again and it said 94%.
That is certainly strange... Hasn't happened to me yet, and I've been monitoring my battery for nearly a week now.
It certainly seems to have more juice in though. Given it a bit of a thrashing this evening and I would usually be down to around 50% our so, it's currently at 75%.
I will monitor for a day or so to see if it is just placebo or not.

Same happened to me overnight. Went up 8%!
Further, I've now done this process 6 times meaning my battery is effectively 160% of what it was???!!!
Have we got any hardware experts who can pass a view on whether this a bad thing to do? Overcharging a car battery can be bad for example.
i've done it 7 times and still boots at 88% battery.
lets see if it did something in the next day.. =P
I've done this and on the first try, it booted with 88%. I recharged it and on the next boot it came with 100%.
Let's see whether there is any real improvement
Thanks anyway for the guide.

it happened in the same way with me.
I have 504 firmware, x10a.
Cant we use the battery information menu? There you can see the battery voltage. The maximum is 4.2V.
Forget the "Wipe Battery Stats".
If you do the steps, except the 1, 3 and 4, the result described in the "8" step will happen.
in other words:
1.Battery is 100%
2. Take the battery off
3. Insert the charger chord
4. Put the battery back and wait for the phone to boot
5. Once the phone boots up, you will notice that the battery percentage is 88% instead of 100%.
In an infinite way.
I followed the steps from the first post and the first time I reboot the phone went to 94%. I then charged to 100% and ran the steps again and this time I reboot to get 77%. I then ran the steps one more time and after reboot i got 100%. I then left the phone on standby and did not use it for 12 hrs and it was still at 87% battery. This is a definite improvement over before even on just standby I was lucky to get 24 hrs out of it and now it seems it can last about 80+ hrs on standby.
Im on .24 firmware with bluesparks rom.
first time i did this it booted at 96% then the second time 86% nothing strange as of yet

The point is to wipe your phones memory of the battery thus learning your phone a new pattern or behavior, so i belive every step from original guide is nececcary.

Yes. I arrived the this conclusion, after 5 attempts from original guide.
I told this in the post 12.
I've done this 5 cicles. It keeps showing 88% but battery life improved a lot. I had to plug every night but now it's my second day without recharging.
Thanks a lot! !!!

I've done this 3 or 4 times now and in 12 hours I've gone from 100 to 87% including a few calls and a small bit of Sat Nav. I also have Ultimate juice. Still very good and would get over 3 days with this performance.
Still 88% all the time when rebooting and wiping the stats though.

Hi all,
I have a question about battery life on the Simply Honey 2.7.2 ROM
My phone is usually idle overnight, but i notice a drop of about 25-30% in 8 hours. Is this usual?
Here are some screenshots
Battery Plot (1.26 am to 9.26am) Battery was 100% at 1.26
System details
Top Apps
Is this pretty normal for overnight battery drain? The Device usage indicates almost no use..so i'm wondering why the battery is draining.
Any help would be appreciated.
Thank you
I'm having the same issue. With Darky's 9.5 the phone easily last a day, now it's lasting 9 hours or so. I just flashed the new ROM yesterday.
This is from the Simply Honey post:
HOW TO RECALIBRATE YOUR BATTERY (by heartagramm):
COMPLETE GUIDE!!!
You'll have to use the phone for about 1-4 days (although it varies depending on the phone and battery used; every phone is an individual). It runs out of battery. Yes. Let it run. Recharge. After 3-4 recharges the battery will "gain" it's performance back.
After 3-4 full charge/full drain -cycles, do the following:
1. Charge the battery up to fullest.
2. Keep it plugged in to charger, and reboot to recovery.
3. On the recovery, go advanced, wipe battery stats, scroll on to yes BUT Don't wipe them yet. When you're ready, quickly remove the battery cable and push to wipe the battery stats.
4. Reboot the phone, use normally. Let it run completely out of battery.
5. Charge the phone back to full. Turn off phone. Charge until it says 100% on the green bar and vibrates for full charge.
6. The Important Part. Remove the charge cable for 0-0.5 seconds and plug it back in instantly. Let it charge to 100% again. Do this 1-2 times again, so you've done this 2-3 times total.
7. Reboot to recovery, wipe the battery stats again as on the step 3.
8. After wiping the battery stats, plug the charger back in the phone.
9. Reboot to ROM. Keep the cable plugged in. Keep it plugged in for about 30 mins to 2 hrs. Unplug. Should say 100%, mine did for about 40 mins after it depleted onto 99%.
And this is the way you should really gain great battery performance.

I'm going to try this and hopefully it works.
Let us know if it sorts itself out after a couple of days...

Thanks. I will try this.
I recently downloaded a Battery Calibration App from the market too (NeMa) and calibrated my battery using that..but I'll try this method also.
Let me know if you have any improvements also.

I switched to Doc's ROM and battery life is back to normal. I'll try Simply again after a few versions.
Sent from my GT-I9000 using XDA App
I don't think there are going to be new versions, because he's now doing some Gingerbread based ROMS.
Which one is Doc's ROM?
I'm on SimplyHoneyV1.0XE and have been for a couple of days. This is my first Simply Honey experience but I think this is the best battery life I've ever gotten on ANY ROM including stock. Given it is a little early in my test to determine just how good it is going to be but I would recommend you give it a try and see how it does on your battery.
P.S. My findings were based on the fact that after a 100% charge, light usage (2-4 phones calls, and several texts) for almost 10 hours I still had 89% of my battery. Pretty impressive if you ask me.

I'm pretty sure they perform the same function. When you touch the "Calibrate Battery" button, the app automatically performs all the steps mentioned (wipe battery stats, mainly).
One app you might try is Juice Defender. I've used it a few times, and it worked well when battery life was an issue for me (I've switched to Axura, and it isn't anymore. Neither with Bionix).
I flashed to the newest release of the Cyanogenmod beta two nights ago and my phone won't charge the battery to a full 100%... I've seen other people post this problem as well. Theirs may stay at like 60%, I saw one person post it won't charge past 19%, etc.
I don't want to flash the ROM again right now, so does anyone know any other fixes?
did you flash cm7 with a full battery? try letting the battery drain to the point that it wont turn on before charging. did you try deleting batterystats in recovery?

That was me who had the 60% battery problem. Here's how I fixed it.
1. Take the battery out of your phone
2. Plug your AC charger into the phone and wait until it gives you the missing battery icon.
3. Plug in your battery
4. Charge for 6 hours
5. Check on it again (it will probably still say 75% for you)
6. Reboot into recovery and wipe battery stats.
7. Viola you have a fully charged battery now.

Download BatteryCalibration from the android market and follow these steps:
1. Load the App.
2. Plug your phone on charge
3. Wait till your battery gets to its max whether it be 70% or wherever it stops.
4. Uncheck the option "calibrate when reaches 100%"
5. Click on Calibrate.
6. Click on Calibrate again (just for good measure) and if it says something like your phone is not supported or battery.dat is missing, then it means you did a good job.
7. Unplug your phone.
8 Drain your battery till 0% literally. (Switch wifi, gps, H+ on while playing Shadowgun....worked for me).
9. When your battery is dead, charge it again and it should reach 100%.
Did you wipe battery stats after the charge?

you can try jug6ernaut's battery fix it might not work since its not a jumping issue but it's the same in that it is not reporting the correct battery amount left

This worked for me, I might have to do it again or something though because now it stays at 96%, much better though. Thanks
About to give this a shot myself. My phone stayed stuck ~82%... couldn't figure out what the hell I messed up on it!
I think as a reminder/heads up, there should be a note on the different ROM threads OP's to tell people they should recalibrate their batteries after flashing a ROM... I had no idea.
Cheers!
Edit: works!

Hopefully I can state this in a way that doesn't scream "I don't know how to use teh search!"
I calibrated my battery stats using the free app on the market after flashing darkside. My phone used to charge to 100% on the indicator (4200+ mV). Now, a couple of weeks later, it charges to the same 4200-and-up charge but the meter tops out at 92%. Two days ago, it was topping out at 94%.
I've re-calibrated using the app, draining it down and charging fully up. Same result, 92% max.
I've wiped battery stats using CWM immediately after charging fully (verifying the charge is above 4200 mV). Rebooted. Still at 92%. Actually, now it's reporting 90% with 4128 mV.
so if wiping stats is a "useless operation", what gives? How is it possible that this method apparently fixed other users' miscalibrated battery meters stuck down around 30-40%?
Try this:
1. Charge as much as it will charge
2. Turn it off and take out the battery
3. While the battery is still out, plug it in and wait for it to show the battery image with the question mark
4. Put the battery back in (do not turn on yet) and let it charge for an hour
5. After an hour, turn it on, unplug, and report back
Note: On step #4 when you put the battery back in it will probably only show like 5% or 10%, just ignore that and let it charge

in cm7, charges to 98% normally, but sometimes takes hours to reach 100%.
I hope i'm not hijacking this thread, but since we are talking about mV i thought this might be a good place to ask....
I've been having problems with my battery levels for a while, i've tried all the voodoo to try and fix it but i can't get anything consistent.
here is what i get....
i have battery calibration app installed, sometimes it will read 4200mV and be 20% charged. Other times it will read 100% charged at 3700mV, it's all over the place, and trying all the suggestions to fix the battery life don't seem to fix it.
another thing i have is it will discharge from 100% to 5% within an hour but my mV will be at 3900+, then it will sit at 5% for another 8+ hours then the phone shuts off, so i plug it in and it says 5%, i let it charge for a minute or two and it's at 20%, i turn it on and it shows that it's above 3700 or 3800mV.
so the phone thinks it needs 3700+ mV to run, but not always, sometimes it will go down below 3600mV and still run
A couple questions
1. can someone post their mV reading at 5%, i'm guessing it should be about 3300
2. what is the max mV that you have....is it above 4200mV (mine never is)
FYI information i've tried fastboot -w, cwm battery wipe, deleting the battery stats file manually, even formatted /system and other file systems to make sure it was fresh

Ok,
I did this and my battery starts off at 100% and all appears to be fine. The next time I charge, it only shows 83% and it is reading 4200mV which should be a full charge. Do I have to do this each time? Is there any other solution? I am running CM7 stable and the battery is an aftermarket one. Could this be the issue? Thanks in advance all.

One trick I've found is unplugging the micro-USB and plugging it back in immediately. When I do this the 4200mV usually drops to the low 4100 range and the % continues to increase.
Only caveat is you'll have to keep doing this until it reaches 100. It takes a while since it seems to get re-stuck at every 1-2% intereval. A pain, but it's a work around from having to pull the battery. :silly:
I have the same issue too but DO I ALWAYS HAVE TO DO THIS METHODS? My battery level drops day by day (becomes %92 max) from %100.
I'd had the issues you explain for AGES.
I'd heard that buying a new battery wouldn't help. But I bought a new, official battery off eBay and I've not had the issue since. That was a couple of months ago now... not saying it will definitely work but at worst you have a spare battery...
What works for me... Charge up as much as possible, then use root explorer and go to data/battd/ and delete everything except the file "uid" then reboot... Should be good to go...
Hope this helps!

This definitely worked for me. I was having repeated issues that full charge/drain calibrations didn't fix. This did.
I had the same issues with charging it ,but i foudn out that the only failproof method of chargin it by using the oem ac adapter and the oem usb cable if you dont have the cable the nokia cables shoud do the trick but the samsung one does not work i dnno exactly why but i tested it myself.

For the past few days my battery has been charging to a max of 92%, whether or not I try unplugging the battery, leaving the phone on the charger, wiping battery stats, and doing all that I can to try to reset the battery stats.
Anyone have any idea?
UPDATE: My phone is still not charging past 92%, no matter how long I leave it on, or what I try to do to fix it. 4167mv max
I have a similar issue, it's been like that for a long time for me. What ROM/kernel are you running? It might fix it to completely drain it, charge it powered off, reinstall ROM/kernels when it is completely charged and reset battery.
Sent from my MB860 using xda premium
drain it until it shuts off and then charge it all the way to 100%.
I too was having this issue after going from cm7 week 5, to week 8. I did what others were recommending and charged to what showed 4200mv, pulled the battery while still plugged in, put battery back in then after it showed 5%, turned it back on and Viola, 100% battery. Try it.
its most effective if you know your battery is fully charged, power it down, pull the battery, while the battery is pulled plug it into the power adapter, it will act like its starting to charge, but then instead of having a percentage, it will have a question mark. pull the power, put the battery back in, turn on, wipe battery stats in recovery and run with it...

I just started having this issue and cant wait to try it thanks for the suggestions.
when this happend on mine all i did was keep using it and it fixed itself. i ran it down maybe to 20% before I got to charge it again and it slowly creeped back up to 100%. took about a week.
I've had the problem, and have run the solution more times that I can count. But nothing ever fixes it permanently. Everytime I run the battery low, the levels get all screwy again. Maybe my phone is just worse than everyone else's, but I had to just give up on it. Would love a permanent solution, but so long as I'm running this ROM (CM7), I doubt I'll ever find one.

I'm in the same situation as you are... I had this problem for a long time now (Guess it has something to do with excessive flashing...) and no matter what kind of solution I do (Wipe battery stats via recovery, re-calibrate the battery, pull the battery out while charging and replugging it) it returns after a day or two.
I want to check if it has something to do with the battery or the device, and if I will remember to do so, I will plug my spare battery for several day's run, but that is subjected to me leaving the comfort of my usual laziness....
Would love if there was a permanent solution as well, thou I doubt that too....
I've had the same problem on a number of different roms and at different times. I find that instead of mucking around wiping stats etc, it has always come good eventually for me.

Didn't really understand what you meant, did the battery percentage fixed by itself and gave you 100% at full charge on one day? out of the blue?
Or did you just got used to have less then 100% battery display?

First let the battery completely drain and the phone shut down by it self. Second step is to pull out the battery and leave it out for 10min, after that take a plastic bag and put the battery in it and place it in the freezer for 15min. after this palce the battery again in the mobile. make sure there is no any moisture on the battery. Then charge the phone without power on till 100%.
By following these steps this will made your battery to charge fully and more talk time

Um correct me if I'm wrong anyone, but doesn't cold kill the battery and shorten its life? I remember my mom always putting new batteries in the fridge and them only lasting a couple days compared to the ones left out that lasted a month or so with same use.

Haha, I got a good laugh out of this one -- you've got to be joking.
I've had this problem for a quite a while now with the Atrix and two different batteries. I've tried dozens of combination of resetting the battery stats, running the battery completely down, and powering up without the battery and hot swapping it in. The hot swap definitely allows me to finally recharge to 100%, but once I run it down again, the problem returns. I've learned to just live with the less than 100% reading -- battery still seems to last a full 24 hours for me.

That trick hasn't worked since nicad batteries in the 90s, and is a really bad idea with our Li-PO.
Drain the battery till the phone shuts off, charge back up while the phone is off.
If it still doesn't get to 100%, boot into CWM, wipe battery stats and power off the phone to let it charge again.
^^ I know it works because I've done this like 2 days ago, and many times before that.
I have had this issue as well for a very long time. I've tried the pull out, question mark, 5% thing and it usually only works for one cycle, then the next only goes to 97%, then the next to 93%, then 90%, and it continually goes down until I have to do it again. Hopefully a permanent fix can be found soon. I've tried clearing battery stats, draining it to 0%, then charging it fully. I've tried everything. As far as I'm concerned, there's no fix as of right now.
Thanks man this worked like charm of 100 witches and 100 warlocks having orgy and satin worship

I too was having this issue after going from cm7 week 5, to week 8. I did what others were recommending and charged to what showed 4200mv, pulled the battery while still plugged in, put battery back in then after it showed 5%, turned it back on and Viola, 100% battery. Try it.

★ATTENTION! I FOUND THE FIX!★
Turn phone off and plug it in to a wall charger. Charge it until your notification light turns green, quickly tap the power button to check battery level. (Usually shows 90%) If the notification light turns on, but the battery indicator is not at 100%, unplug phone, take out battery and put it back in. Now plug your phone. It should be 100% now. For the final fix: go into "Android Recovery" and select "Mounts". Mount Your SD card and Emmc. Finally wipe battery stats. Reboot phone.
This method worked for me. I am 100% sure this is the fix for this problem. This has to be done every time you flash a new rom or when your phone freezes and you screw up calibration by pulling the battery while it is still on. BTW, this is my first post so don't be mean to me!

Satin worship, is that like old fashioned polyester worship?
Call a tut or a fix or a what every you want.
Ok so you been hoping a few ROMs and kernel a few times and as usual you always forget a tiny but important detail. Charge your batteries at >95% before ROM hoping!
So now you are stuck with a battery meter which does 15% to 0% in 3 secs! This is basically a messed up battery meter! Some call it miss calibration of the chip, some say the battery's fried! But the truth is far from it!
You google and get the following results:
1.Battery recalibration app for play store(simply it never worked for me was placebo)
2.CWM battery reset(what i felt was doing the same thing the app did only in the CWM menu)
3.Recharge and discharge continuously till it becomes ok!(works but time consuming)
So how to correct the rogue meter?
Simple and easy:
1.Discharge completely.
2.Recharge in offline mode
3.Wait till its a 100%
4.Remove the battery and wait 30-45 secs.
5.Reinsert the battery and then again recharge in offline.
If yours was truly a meter problem then when you insert the battery and charge it after step 5 then the charge should show <100%
Do it check it out if it worked out for you and let me know!
Cheers Guys

I followed the advice, but it's the ubreakable circle. I charge it till its 100%, reinsert battery, it shows 50-60%, charge it, reinsert and it is half-discharged again! It;s been a couple of days while I do the thing. Some say it may work giving the battery a tough time.

If it's still so much messed up i advice you to change the battery, Li-ions tend to loose 4-10% of the capacity over the years depending on the usage and environmental factors.
