Help, my phone is dying even though the battery still reads 9 percent left. I am using darkstones froyo build v3 and 2.12 radio. Is there some way to reset the battery to make it go down to 0 percent.
I am using the darkstone v3 Froyo build, the darkstone kernel, and 2.12.50 radio

The only way I have ever gotten my battery to reset was to charge it to full in WinMo, and then it reads normal in Android.
That works for getting the battery back to 100 but mine does that. Just dies early.

If your battery isn't reading 4.2v at 100%, then you need to recalibrate it.

Hi,
I just recalibrated my battery. Followed the steps in the other thread.
I deleted the batterystatus.bin file (i think that was the name) and put everything on to drain the battery. I think i lost power at about 9% left on the battery. Tried to turn on the phone, but the battery was without power.
I let the phone stay turned off while charging through the night, but i only get 4085 mV, and i only reach 98 % now...
the voltage % drops rapidly to 87% now, after 1,5 hours with limited use.
Any suggestions, guys?
EDIT: I have not punched any code as stated in the other forum : "rm data/system/batterystats.bin"
Where do i punch this code??
I use "ROOT Explorer", purchased from the Market.
Rm data/system batterystat command u enter in terminal to delete the battery stats.
Charge to full, unplug and then power off. plug in and Charge 30 minutes. Unplug and power on and do the command in terminal to delete battery stats. Then reboot and charge powered on for another 30min-1hour or til full.. then it will be good.
Those are HTC directions. Not word for word of course
I recalibrated the battery and followed the steps along with term emulator. My battery will charge to 100 and read charged but it still wont read correct on the bottom end of the battery. My phone still dies at 9 and that is my problem. Help me someone.

hi,please move if in wrong place, im running rcmix hd rom and wanted to calibrate my battery.
it says to charge fully while phone is on until green led which i have done,
it then says to power off phone and charge until green led but this is the bit where im stuck.
because i have clockworkmod, when i power off phone and charge, the recovery menu comes up???
i have been charging while supposedly off for last 3 hours, my led is orange but is my phone off??
i shouldnt have thought it would take that long to charge a powered off phone cos i charged it fully while it was on??
so if anyone can explain what i need to do that would be good, or if anyone knows of another way to calibrate my battery without having to charge it while off that would be handy too, thanks
Try the new modded recovery with full shutdown, no more auto clockwork start

Yea sure, here is the thread http://forum.xda-developers.com/showthread.php?t=1027835
I'd pick the 3.0.2.4_r1. It flashes like a rom in cwm, then just reboot recovery. But now to access recovery from turn off you have to boot into fastboo first, vol down+power
Thanks for the link ;-)
Ok so I just flash it like a rom and reboot, and that gives me the ability to charge while completely off??
And if I need recovery then I just go into fastboot mode?
Thanks mate

Pretty much, you can try it out easy. Flash, then go to advanced>reboot recovery and make sure it says 3.0.2.4_r1 then press power off and plug in your charger

not that it matters as you are sorted, but phone does charge in CWR but you need to use a second party program i.e QtADB to monitor charging and delete battery stats only when it's at 100% charged.

hiya, lol you know what, honest truth, i looked it up on google earlier and found a different forum and saw a post you made about that, i clicked the link but i couldnt really understand it.
well its been off charge nearly 2 hours after calibrated and has only dropped 1%, so very happy at the moment
thanks
what about the method whereby u use currentwidget to monitor the charge.
when it is at 0ma then reboot into cwm and wipe battery stats?
does that work too?

The idea of charging it whilst off is to ensure it is at 100% when the battery stats are wiped, with some phones they erroneously report fully charged when they arent, hence charge to 100% turn off charge to 100%, reboot and charge (to replenish charge used in rebooting) then wipe battery stats. People are worried that older CWRs would boot when phone was turned off making it hard to ascertain that 100% charge was attained.
so what is the correct method of resetting the battery stats?

yeah i noticed that too.
100% battery 0ma on current widget.
reboot into cwm, wipe battery stats and reboot.
once booted up it shows 99% but charge again and its at 100%.
have you tried the turning off method?

It will work, but if you want the optimum results you must charge the phone back to 100% after rebooting before you delete the battery stats.
Hi all. I'm using Miui rom 1.6.17.1. i installed it without charging the phone fully and now my battery life sux :-\
So i turn my phone off and try to charge it for caibrating in CWM but it turning on once i plug the charger....
I understand thats it a known issue, so how can i do this thing?
calibrating in miui? i would say its impossible
when my charger is pluged in an i restartmy phone then spring the percentag from 40 to 55
sad ... same here ... but you may try to let your phone to complete discharging battery, until go off ... and after that charge it 100% without using the phone and clear battery statistics from cwm.
Well...may be it was stupid thing to do but i flashed froyo back on...calibrated and than flashed miui with 100%
well ... your battery will still suck...cuz its cm7 base..which has battery drain
cm7 <3
Yeah...thats a problem, but i'm in love in miui
The latest cm7 should have addressed it already.
I was in the same situation as you, battery only lasts 6hrs on any given day.
My battery now lasts more than a day even on moderate use n 3G on all day. I initially rest the battery stats then performed a full power cycle.
Now when I upgrade between miui versions, I always ensure that the battery is 100%

may i know how to calibrate battery ?
i m in miui rom
You can't calibrate the battery properly in MIUI as it is supposed to be done with the phone off, MIUI or rather as someone else has mentioned its down to CM7
It can't charge the phone with it switched off because I believe CM7 is based on the Nexus and the Nexus cannot charge with the phone off
I could be wrong though, but the above is what I have gathered through reading about it

The topic pretty much explains it. I've been using different modified stock roms and now I'm on the latest nightly of CM7, and I keep having this issue. After a reboot at around 50%, the battery drops to 15%. The weird part is that while I continue to use the phone, it slowly rises back up to sometimes 30% and then starts going back down. I've always cleared battery stats when flashing and calibrated (which I believe is unnecessary), but I don't know if this is a problem with the battery, the phone, or if anyone else is having the same issue?
Attached is a screenshot of battery usage. You can see I never actually charged the phone.

anyway guys, you need to recalibrate your battery, its not being read accuracy.
download BatteryCalibration from the market, charge your phone till 100% (not just 100% but when it beeps, that its truely at 100%), then use BatteryCalibration to calibrate your battery, and then drain it to 0.. (crank full brightness, turn on LED flashlight, blast internet radio, whatever makes it drain faster to get this part overwith), then recharge it to max.
so;
charge to full 100%
while still plugged in, run BatteryCalibration
discharge to 0%
recharge to 100%
battery successfully calibrated, you will now have an accurate reading
I had exactly the same issue on 3 different custom roms....finally resolved by going bck to stock rom

This thing only happens on CM7 for me. It had 40% before reboot and like 15% after. However mine only increased to about 17% then started dropping as usual. This never happened on any stock ROMs I've tried(stock, not themed/modded stock).

did you
did you rsolve the problem ? how? I have the same problem and I tried more stock roms ... I don't know what tot do ....
Its nothing to do with calibration etc, its just how the fuel gauge chip works, it learns and more accurately reports usage over time. For example, if you reboot and (I can't remember the actual voltages for the S2) you have 1200mV, the chip goes, "ah, that is 15% battery." Then as you use it more, it relearns its settings and goes "aaah, my mistake 1200mV is really 30% battery. I'll display that instead."
Its been covered frequently that "calibrating" the battery of the S2 in any way but actually using it, is next to useless.

same here and I got the 2000 mAh samsung battery back in the days but now it happens with both of them also when my phone shuts off the screen brightness start flashing weirdly
After i flashed cm7 a long time ago i noticed that after total charging (100%), when i disconnect the phone it immediately says 99%, i have callibrated the battery and still the same... is not something too important either, but it stills bugging me :/
any help?
btw, it's a red lens defy...
thats just how it is. When plugged in its using the power from the plug and when you disconnect it, then its drawing power from the battery so it will read less. There is no helping it, just what happens it doesnt mean your phone will discharge faster or anything.
99% battery after plug off happens to me always on every rom I tried (even stock one).
Actually I don't care at all.

On stock...? Rally? Didn't know there was a stock ROM with 1% increment. Stock ROM's only have a regular battery indicator and in battery's settings it shows the battery state in 10% increments - 100; 90; 80 and so on...

There is no fix its just that the battery is fuller when plugged in. If you have battery monitor the mV will go down as it stops drawing power off the plug and draws it off the battery. You can never be 100% when you are drawing power off the battery its a simple fact

Well, i had a Moto CliqXT(Quench) running cm7 that keeped the 100% for a while after unplug, that's why i asked... but thanks for the info, i thought my battery was damaged or something like that...
maybe it's something related to the kernel, as the cliqxt have the bootloader unlocked and many optimizations were made to it's kernel... just wondering...
