Good day fellow XDA members. I am currently running an unofficial Cyanogenmod ROM for my Huawei Ideos x3 u8510. So far, I love it! I have already calibrated my battery after flashing the ROM, by charging to 100%, using Battery Calibration from Play Store, letting it drain to 0% and charging it to full nonstop. My situation is the following, my battery still drains after I have calibrated it, (I did it yesterday), when I use the phone. If I don't use it, 1 or 2% drains aprox. every hour or hour and a half. After investigating here and other pages, some say that after calibrating your battery you have to let the ROM settle it after a few days, that way it's life gets better or "more accurate". Ok, I now need patience. My second situation is this, I want to know some of the BEST possible ways to save battery on Cyanogenmod, as battery lasted longer on my Stock ROM. Here are my descriptions:
-Use wireless networks when necessary,
-Brightness all the way down.
-Every basic thing I know.
Ok, those are the basics, but what are the best CPU settings to have the best battery life and at the same time have a fast phone? Here are my current settings:
-Governor: ONDEMAND
-Min CPU: 245 mhz
-Max CPU: 600 mhz
-Compache RAM usage: Disabled.
-Use JIT: Checked
-Enable surface dithering: Unchecked.
-Use 16 bit transparency: Checked
-Scrolling cache: Default enable
-Allow purging of assets: Unchecked
-Disable boot animation: Unchecked
-Lock home in memory: Unchecked
-Lock messaging app in memory: Unchecked.
My current kernel: 2-6-35.7-perf
[email protected]#1
So, can anybody suggest me the best settings to save battery life and have a good to great perfomance? Please answer, there have been 2 forums I already asked, but no one has answered.
Seriously? No one?
1% for 1 or 1 1/2 hours battery drain seem normal..

Thanks for your answer, but I forgot to mention something. My battery drains like 1 or 2% every 5 minutes when I use the phone. I wanted to know what SETTINGS or suggestions are best for battery life saving in CM 7.2.
By the way, I flashed a new ROM yesterday, it's very complete! The thing is, when I was charging my battery on the outlet, the indicator showed 89% of battery charged. After that, no more than 30 seconds passed and my phone was charged! Weird huh? So, I left my phone charging for 5 more minutes and then, the indicator showed 89% again with the charger connected! What I did was download Battery Calibration via Play Store, charged to 100%, eliminated batterystats.bin via this apk, and I think my indicator got "fixed".
My question is this, do I really need to recalibrate my battery or what I did was enough? I ask since I read battery calibration is a myth. Is this true? Or do I really need to calibrate it after flashing a new ROM?
Please answer!

cpu settings are subjective for every device i guess. i using vsel formula to calculate it. frequency/20 + 2. and do stability test to make sure the settings are stable.
may i know CM 7.2 from which build? last time i using cm 7.2 fuzz, i had to replace battd file for battery to indicate properly.
i had no idea about the myth because im not expert. batterystats.bin reset itself if you unplugged your device when it full charged.
my suggestion, use for a few cycle and see if any improvement.:good:

Actually, it's an unoffcial ROM I found, but it hasn't been the only one that makes my battery drain. Basically, it's been all custom ROMs I have tried out. I'll take your tip, thanks! :good:

couple weeks ago, i pulled my battery out when it was at 81% started it back right away and it was 45%, did it again today, it went from 71% down to 29%, my battery reading is tripping, I noticed. MY BATTERY IS HORRID, i lose 1% power per min on the lowest screen brightness display setting, could this have anything to do with this?
side note:
using my battery. battery stats says that my screen is causing 99% drainage.
my buddy battery: my screen is 80% drainage.
bad battery??? it still drains really quick with my buddy's battery, but DOES perform better. but not by much...
another thing, lol..... charging differs. sometimes it can charge like 10% every 10 minutes, and sometimes 30min for 10%.....its just weird. and my phone doesn't last me longer than 10 hours full charge, minimal use.
You may want to look at your battery health under the battery information menu.
Also to better understand and provide support we need to knock out a few things.
What is your current set up? ( rom,kernel, etc)
Have you done a battery calibration at all?
Have you run things like cpu spy to see what apps could be at fault?
All of this can give the community a better picture of what may be going on
Also I pull my battery alot because of testing and sleeps of death and I see very good battery life still. Atm 15 hours @ 72% and I am far from conservative.
SF.UKB.CR.
kernel is the community TSM, battery still was wierd in stock rom, sc 2.9.2, and others.
battery health is good according to spare parts at 3850mv.
currently charging its been at 16% for 10 mins.....

Just FYI, you don't have to do a battery pull when you get SOD. Just hold the volume up and power buttons until you see the samsung logo, then let go. This is a hard reboot of your phone. That will save you battery a little bit as you won't be pulling it as much.
I've got this problem with my tab (quick battery drainage). Symptoms would be your 100% charged tab would go down to 0% in unusual shorter time ( like 2-4 hours). You put it on charger and tab would be charged back to 100% again in substantial short time like 2-3 hours instead of 6-7 hours.
Well, after looking at this issue I think I have come up with solution.
At least, my tab looks like it's back on track... though, to say for sure I would need another couple days of testing.
The problem is not runaway wild application on a background but battery control circuit. This chip reports to OS much smaller battery capacity as it is for some reason. I will not go into details but here is what you need to try:
Flash stock kernel (may be custom kernel is not the reason for bad chip calibration and I'm 90% positive but just to be on safe side). You don't need to do factory wipe in OEM recovery for our purpose.
You also don't need to wipe batterystats.bin or use "Battery Calibration" apps from market (which does exactly the same wipe just in more end user friendly way). This wipe serves no other purpose then refreshing your usage statistics.
You also don't need to drain your battery all way down... nice, this way you don't have to wait for too long.
Well, here we go:
charge tab somewhere in between 80 and 100%.
edit: remove charger
shutdown tab (not put in hibernate/sleep) for 1 hour.
edit: turn tab on and run it for 30-40 min. or whatever it takes to drop charge to 40-50%.
shutdown tab again for 5 hours (overnight).
turn tab again and check... you should be fine now, charge it again 100% and use as usual.
That should do correct chip calibration.
PS: the reason why this chip calibration went bad at the first still remains open.
EDIT: just want to give a shortcut for those who does not feel like reading through the thread.
http://forum.xda-developers.com/showpost.php?p=16771651&postcount=41
Edit: here is calibration procedure which was modified down this thread ...
1. in CWM/recovery let it sit till battery in terminal will show less then 3700. The less you can get it the better. 3400 is probably absolute minimum.
2. shut down tab and let it sit for 1 hour.
3. plug it to charger and charge it for 5 hours.
4. disconnected charger and let it sit for 1 hour.
5. boot up your tab and test it, it your battery still not calibrated you can flash back your backup and repeat calibration procedure.
Edit: if you physically disconnect battery (you have to disassemble tablet) and keep it for couple min. that would trigger FG chip to start with default SOC curve.
Any follow up? Did this fix work for you since yesterday or anyone else?
yup, this is it...
This is how properly calibrate sg tab's batteries. There are some variations to the process but essentially battery will be calibrated in two measurements which stand apart by minimum 40% when battery is at rest on time intervals 1 and 5 hours.
No need to do factory reset, wipe batterystats, use battery calibrator apps from market or dance around with rain stick... all this will give same result as woodoo magic... though if by some reason battery calibration conditions are met then one may claim a miracle.
*sigh of relief* looks like this worked. More people that have this issue should now about this. Thank you for the fix.

Is this the same as the Sleep on Death (SOD) syndrome? that while charging it dies overnight and then you have to long press the power button and/or charge it to get it back?

How long your tab usually works on one charge? if 8 and more hours - then no, I would think that there is a bug in Android charger control.

May I ask what do you mean by rest time intervals of 1 and 5 hours?
Does it mean that the calibration will only take place when the tab is off for 1 hour, then switch on and used till battery depleted by a further 40% minimum and the switch off for another 5 hour. Correct?
Also , is this 40% refer to value before or after calibration? I asked this because when I restart my tab the value changed (ex: 36% before restart to 53% after restart)

Yes that's correct.
Fuel gauge chip will take 1 measurement of open circuit voltage and internal resistance only when battery is at rest (no charge/discharge) for at least 40min. - so I say 1 hour just to be sure...
Consecutive measurements, from which gauge chip can derive capacity of the battery have to be at least 40% and 5 hours apart.
Technically speaking, that 40% difference can be in either directions. Say you have 40% as of now, leave it in rest for 1 hour, then charge it to 100% and leave it at rest for 5 hours and you will have same result.
Condition "at rest" means voltage change less then 4mV (or mkV) per sec. - I don't remember.
When tablet is in sleep some background processes may awake tablet briefly and reset the 1 hour counter - so to make it work for sure, simply do shutdown.
if you want additional reading on my findings then look here:

I tried this method...
1.Charged tab t0 80%, then shut down (removed charger) for 1 hour.
2.Turned on tab and played games for about 45min till battery was 49%.
3.Turned off tab and let sleep for 5 hours (charger still removed).
4.Turned tab back on and battery reads 79%, used for about 20min and battery reads 68%... Seems battery drain is still happening?
Right now i'm charging the tablet back upto 100% then perhaps try this method again... Did I do something wrong?

same problem im facing. This is why im wondering is the 40% value of before or after calibration. Because although it might drop 40% before calibration is done, the real drop value might be less then that. Which means to the chip it might just see a drop of example 20% of real drop and hence it didn't perform the calibration because conditions of 40% is nt met.
I did forget to flash back to the stock kernel (using pershoot's).
I just flashed to doc's slim 6.5 which has a modified stock kernel (couldnt find just the stock kernel and my internet is too slow to download the entire stock rom.). Going to try this method again but starting at 40%
1.Battery at 40%, shutdown tablet for 1 hour.
2.Charge tablet to 100% (while shutdown)
3.Leave tablet shutdown for 5 hours
4.Pray to droid gods, find my rain stick and begin dark resurrection ritual while watching true blood.
My only question now is... Should I turn the tablet back on after the 1 hour shutdown? Or should I leave it shutdown and just plug in charger till its 100% charged, then let it stay shutdown for 5 hours?
This is what worked for me:
1. Charged tab to 100% removed from charger.
2. Power down for 1 hour.
3. Power on (tab at 96%)
4. Drain to 46%
5. Power off for 5 hours
When I powered the tab back on after the 5 hours, i used it for a while and rebooted and the battery reading stayed the same which it wasn't doing before the calibration. It has been draining and charging at a normal pace since then and has remained the same after reboots and ROM flashes since the calibration.

I'm going to go ahead and try this method right now! But for me... sometimes my battery will not charge unless the unit is shutdown (ever since battery issues started.). I hope this time it will charge while its on.
Also the instructions say to flash the stock kernel before trying this method... Did you do this? And were you able to flash back to pershoot's without issue?
*Update:
It doesn't look like its charging, (system on). Should I just shutdown and charge it to 100%? Then continue with said method? Anyone know if this method will work while tablet is shutdown through the entire process?

My tab was charging while on, sometimes it wouldn't show it till after a reboot. I did mine from stock 3.1. (A backup I made before I took the TW OTA) I have not re-flashed pershoot's kernel and probably wont till the bug is worked out. I did however flash the deodexed stock TW and flashed a theme and have had no issues.
Edit: if its not chargin while on, i would charge it all the way while off then turn it on so it can read the battery then start the 1 hour power down.
Correction guys...
I was sure that our p7510 model was using TI bq20z75 fuel gauge chip but with new information looks like it's Maxim 17042 chip... It's embarrassing but I have to stay corrected. TI chip would calibrate itself in procedure outlined above as for Maxim - I don't know yet. I'm looking at it.
These are good and bad news. Good one - with this new fact, it's very possible that the reason of chip's SOC counter corruption is in software. Driver for Maxim is pretty messy and complex (because it's messy). In contrast driver for TI is simple and straight forward (because TI chip is smart). Software can be fixed but problem in hardware design not so easy.
Well, I will report back when I find something.
So, will FillTheVoid 's method work with my GT-p7510? :x

A lot of this is way over my head, but my battery calibration seems to be accurate, although I can't be absolutely sure because I have no stats from the previous calibration to compare it to. I do know for sure that after this process the bug of it draining then after reboot going back to what it should be is gone.
so i guess we need to flash back the stock ROM w/o TW for this procedure to work? I was trying the same steps with StarBurst + pershoot kernel it seem that it doesn't work. Anyone manage to calibrate with pershoot kernel?
Hello guys, I know the CyanogenMod for Galaxy Ace doesn't is official, but, works good, I recommend, but... I'm stay with a very boring problem, on the batery. My percentage it seems that is not synchronized, and the battery ends fast, but have one the problem. Suppose my battery is in use by 90% and a short time and then drops to 80% and is a long way, and then falls back again, but when he gets 20%, it is to leave an hour or two between 20 % and 10%.
Someone else goes through this?

i had similiar problem. cm 7, battery drop from 100% to 90 % in few seconds of use. And 20 % last sooooo long. oh and i forget to mention that i have calibrated battery so it didn t help. on stock rom i didn t notice this problem. ok, it can suck either, however it isnt as bad as it was on cm7.
Are you waiting when you battery is charged to 100% or disconnect it from charger? I must wait some time when battery is 100% charged (let you phone on charger), I think on lookscreen you will get an information that you battery is full. Second are you using CM 7.1 or CM 7.2? I fell CM 7.2 is pretty bater in battery saving then CM 7.1. Using now CM 7.2 form Axel RC1.
I've calibred my phone, but doesn't effects. CyanogenMod 7.2? How can I install this version of Android 2.3.4 ~ 2.3.7 on my Galaxy Ace? I'm using the Cyano 7.1 RC1 Cooper KANG with kernel Ketut.
I can find it in "Development section"

Yeah, about that. I myself have noticed a little bug with that too. It sometimes say 100% charged without it being charged. Don't know if its the faulty meter or the actual battery. Either way, I let it charge for a while after it says that and it works.

I am partially agree with gradonnn here. Please everyone read my this observation carefully. I observed it on 3 Galaxy ace (all non-rooted with stock ROM, 2.3.4) (One was mine and other 2 are friends' phones, all 3 of us observed the same.)
With the stock ROM I installed battery percentage indicator and charging from 20% to 100% on widget indicator showed in about ~90 minutes of charging. & everytime, It showed 100% I disconnected assuming my mobile was fully charged. But then It started to drain after some use and stopped at some particular point say 83 or 78 percentage. First I thought my battery was bad, so I got replaced from samsung service centre. But again, second battery was doing the same.
Then, I googled about it and came to know a good battery of SGA (or any other smartphone) takes nearly 3 hours to charge from very low (say 5%) to full (100%). Now, when charging on the stock ROM showed 100% (in notification bar from Battery Indicator Pro & Battery Percentage Widget on main screen) the mobile was still charging and almost after 1 hour notification used to come with notification sound that "Battery is 100% charged!". I observed same thing with 2 other ace of friends. "THAT" notification was final to consider that mobile was 100% charged and after disconnecting, it didn't drain faster in any indicator.
I am also using CyanogenMod and the problem with this ROM is, the last notification of status bar doesn't come even after nearly 4 hours of charge! (believe or not, but I did wait for that notification sound many times!). & Just 90 minutes of charge the indicator starts showing 100% same as stock ROM did. From last 2 days, I charged exactly 1 hour more after it showed 100% and believe me, after disconnecting your charger battery won't drain fast.
Now, if you're asking whether I have used calibration tools, yes I did with above observations already. & I used Juice Defender, display brightness at the most min level setting offers, GSM line only, Wi-Fi was on hardly 1 hour in 1 day, and ~40 mins of gaming. With these settings/use and stock ROM my battery was down to 50% max at the end of day.. BUT, with CyanogenMod, it gets down to ~20% at 7PM in evening. I believe CM eats more battery, but observing the speed & facilities it gives, it is the best custom ROM for me.

That is because the notification is not a feature of cyanogenmod, but is of Samsung.
Battery percentage is inaccurate in the Ace. Charge your phone on a stock rom and when it reaches 100% the notification won't come either. It'll have to continue charging for another half hour or so then the notification comes.
So same thing with cyanogenmod, charge longer even if it shows 100%.

That's what I said in the first place.. (Plz read my post again )
On the stock ROM, even if after 100% battery indication, I had to charge ~1 more hour until the notification came. My CM 7.1 did never notify me even after 4 hours of charge.. (which is more than 1 hour longer than stock ROM) That's what I said too.
BTW, Does your (or here anyone's) CyanogenMod give out notification of 100% battery charge?
Hey guys, i fell that resolve, but, i'm testing. If resolves, too late I share.
"This is by design. Your phone will slow down and eventually stop pulling charge at or slightly greater than ~95% regardless of what your battery indicator says. This is to extend the overall life of the battery, as constant 100% to 0% charge/discharge cycles will cause it to fail prematurely." from Nexus S FAQ thread

Samsung ¬¬
So I have just flashed the CM7 ICS Themed BETA, wiping everything.
I then charged to 100 percent, and used Battery Calibration app.
I have just setup some apps, and I have lost 10% battery life in 40 minutes
Display is using 85% battery life apparently.
Please help?
It can take up to a week to fully calibrate the battery. Since the battery doesn't have memory the phone has to get a feel for how much juice it actually has. Try it for a few days running the battery down and then charging it to full without unplugging. If that doesn't work you might want to try charging all the way then reflashing and immediately do a calibration.

Yeah, I'd calibrate the battery - wouldn't hurt.
Ideally always flash on a 100 % full battery to avoid problems like yours..

Cheers guys I've taken this all on board.
I'm on 13hrs on battery, its showing 16pc. Battery calibration app shows 3609mv however. This doesn't seem right to me. Am I correct in assuming the phones battery power is the mv listed and no battery is more like 100mv??
Could anyone explain the 'mv' term to me?
Is 0mv when it powers down? Is this indicative of power?
Thanks.
Lithium ion batteries never fully discharge. If they did the battery would not recharge again.

mv referers to mV, as in Milivolt. Most li-ion batteries are rated at 3.7V or 3700mV. A nominal full charge should be around 4.2V or 4200mV.

That's 35 minutes of active use. 10% isn't outside the realm of the possible.
I usually can go a full day on 60% battery, but this morning Facebook, the interwebs and text messaging put me from 100% to 77% in the course of 30 minutes. Draining 10% in 45 minutes does not seem out of the realm of possibility
I get mine to last around 20-26 hrs on a single charge, of course depending on use. but i hardly leave the house and dont use it a whole lot. One thing to make sure of is setting up profiles on SetCPU and/or undervolting. i just posted my setup on another thread. http://forum.xda-developers.com/showpost.php?p=20284361&postcount=28
so after you clicked the battery calibration button and it said calibration successful, you're wondering why the battery is dropping so fast under use right away?
Easy answer my friend, when you first use the battery calibration app, the first cycle (when phone is being used) will always drain a lot faster than the 2nd and 3rd time around.
The battery calibration app, wipes the battery stats, and makes a new one, however that does take at least 1 - 2 times of a full charge/discharge of the battery. There is a battery tread in the atrix general forum i believe for cailbration steps, etc to go about successfully doing a complete calibration when flashing from rom to rom.
Hope this helped
Hmm, maybe I am just upset that I have to charge every night.
Coming from a BlackBerry 9780 I could go 2 days with semi-heavy use.
I am now using the official Motorola cable, and only charging from very low to full.
Thank you for the advice.

Try getting one of these:
4800mah extended battery
1900mah extended battery
Problem Solved.
Bluetooth radio was killing my battery. WiFi is fine leaving it on as it disables in stand by, but bluetooth was absolutely draining everything.
thanks for the update
I agree, 10% loss in 40 minutes of active usage is not bad. If the OP had better battery life before he flashed to new ICS themed CM7 beta rom, maybe the new rom is to blame??? I'd OC/UV, possibly with the latest faux123 kernel.

Thanks for the tip!!!
I've bought a new legit/official (has holo, serials etc.) Atrix battery.
Charged it to 100%.
During usage, its draining literally 10% an hour with very light usage (several minutes an hour). In short its draining at three times the speed of my 1 year old battery.
I've tried wiping battery stats but that didn't work.
Any ideas, or is the stats just buggered and I just gotta run it in? (ie it will go to zero then sit on zero for 5-6 hours lol)
note I've gone back to my original battery in meantime rofl
EDIT: The actual problem is that the batt is reporting much less capacity than it actually has
|The new battery is great capacity wise lasts till midnight
However the stats are still totally screwed, it will say 1% by midday, then hum along until midnight fixed at 1% (I dunno exactly how long for as I can't take the risk of leaving it off at night then its dead and I don't wake up for work in morning). |
Could just be a bad battery. Considering the old works fine that's probably the problem.

I have a similar problem with the original battery that came with phone it drains the charge quickly to 1% and on one 1% it gives a battery life of more time than the time it took to discharge from 100%.i was thinking of buying a new battery but now i am confused that what should i look before buying the battery to get a battery that can show me the exact charge on the indicator.
I have tried all tutorial of calibration used different roms and kernels but nothing seems to solve the issue.
well I might try that then, just let it run to zero see how long it lasts then see whether the stats come good over time
OK help needed.
The new battery is great capacity wise, lasts from morning to bedtime with >2 hours of bluetooth music, 30 mins calls, a ton of texts.
However the stats are still totally screwed, it will say 1% by midday, then hum along until midnight fixed at 1% (I dunno exactly how long for as I can't take the risk of leaving it off at night then its dead and I don't wake up for work in morning).
Aside from wiping stats which I have tried, is there anythnig else I can do?
I really want to use it, like I said real life capacity is great, but if its always giong to be reporting 1% its a bit dicey not knowing how much batt you really have left...
same issue with my spare battery not sure wtf is going on
When I have battery stat problems the following has always fixed it:
1) leave phone on until it dies
2) take back off phone and plug into wall charger
3) after batt symbol shows 100% (without unplugging or turning off the phone) remove the battery. After a minute or so battery symbol will have question mark
4) put battery back in and leave it for at least 2 hours (seems like I have had to press the switch sometimes but you don't want the phone to reboot or you will have to start all over)
5) reboot into CWM and wipe the battery stats
6) reboot and it should be good to go
Anyone else found a fix to this yet?
I'm now running ICS (turl build) issue is still there.
Steps taken to resolve
- discharge to zero
- charge to max
- wipe stats
still there.
The weird thing is that the actual capacity is fine, it can last all day no worries, just from midday onwards it thinks its 1% so has annoying LED flashing at you, also you have no idea how much batt it actually has.
Edit: I just realised your suggestion above has extra step (take batt out of connected atrix then insert again). I guess I'll have to drain it again and do it overnight... gah

Nothing will work i have tried almost every tutorial. Recently i found out the phone is showing the the full capacity of battery only 500 that's why i think we will have to change that with the actual voltage to get a accurate battery indicator.What's ur battery full charge design check if from the root exploler
/sys/devices/platform/cpap_battery/power_supply/battery
My phone uevent is showing this
Powersupply-capacity=5
Powersupply-voltage-now=3836000
Powersupply-temp=260
Powersupply-charge-fill-design=500
Powersupply-charge-counter=1

I'll try the insert empty bat into already connected phone, charge to 100% remaining off, repeat trick overnight, then report back.
FWIW on my 'good' battery which is 1 year old ROFL it says 1880
not sure how changing it would help though or is even possible?. It must be dynamically reported somehow as my good battery gives me a 'good' stat.
I use battery calibration and it worked, have it
http://bit.ly/Ah732P
I'm guapurrin
the battery is charging calibration if you have to load it to calibrate

How much is ur other battery showing.I have tried different ways but was not able to change values.
500 same as you! second drain and calibrate did nothing
Maybe theres a faulty batch of batteries and we both got one
Can people PLEASE stop telling us to calibrate we've BOTH DONE THAT MANY TIMES NOW. The problem is that the capacity of the battery is being reported as 500mah not 1930 or whatever its supposed to be. THe actual running time of the battery is fantastic, just thinks its at 0 all the time lol
/sys/devices/platform/cpap_battery/power_supply/battery
Powersupply-charge-fill-design=500 - should be ~1900mah
