Battery life is really relative, you can't control everything you do on a daily basis on your phone. You can't control the number of email, text message you received, etc. or the signal reception.
So, perhaps the battery now die faster because you change the way you used your phone? It's a possibility.
It's you.
I say that because you don't follow instructions.
Step 1 is to CHARGE FULLY FIRST. Where did you see that it says let it die and wipe?
Reading is fundamental.

I use my phone the same and on bionix 1.8 thread someone posting two ways to do it one was chargefully and wipe and they other was let die then wipe..
Should I charge fully then wipe now to see if that will fix?

Bionix says to charge fully then wipe..
I doubt it's possible that reconditioning would worsen your battery life. It could be a bad app or a setting that needs to be changed. For example, the Facebook app is defaulted to refresh itself every hour.
Aside from reconditioning (which really is just to kind of calibrate your battery status with the rom) it's best to check your running apps. If you leave GPS on, some apps run it in the background etc etc.
I think people spend too much time tracking their battery life that they ultimately cause it to worsen. No need to wake the screen every 5 mins to track battery etc. I get EXCELLENT standby time using bionix mainly bc I don't take out my phone unless I need it to use, vs tracking battery.

Yeah that's the thing when I first flashed bionix1.7 my battery would last forever buy now even on standby without checking my phone it will die.. It didn't do that before the failed attempt at battery recondition which I should not have done in the first place hopefully it will get better

There's no guarantee that your battery will be fixed once you do it correctly. You could just have a defective battery. My first Vibrant was defective that could not get any reception and on top of that my battery would drain real fast.

Do I really need to say it again? Charge fully, then wipe!
Actually, You are supposed to let it charge fully > let it die > plug it in & let it charge (While off) > wipe batt stats > boot > done
I also read a post where it said letting the battery die completely is bad for "health" I guess I'll just not mess with it at all lol

Er, if you wipe the stats, won't it "forget" the draining and charging you did first, making them pointless?
i reconditioned my battery when i flashed bionix 1.8 and haven't noticed any difference in battery life.

Simple answer, no! You will wipe all battery stats previously stored. Starting with a fresh charge and no batt data the fone will have to re-learn the battery data and this should give you a more accurate representation ( cuz thats all it really is ) of battery state from that point on. Hope this helps.

No, his point is that you have extraneous steps. Wiping stats AFTER a charge--drain--recharge is pointless. All you have to do is charge to full with the phone off, wipe stats, reboot.

Yeah, in theory you can reduce the life of the battery. But batteries are cheap, and I doubt I'll ever have this phone long enough to see my batteries go bad.
Ima just leave my phone alone the roms are good enough

Exactly. Why charge it, drain it, then delete? The stars start over. The draining and charging are forgotten.
Sure, you wasn't to start fully charged, but draining it first seems pointless.

"Battery recalibration
If you're experiencing higher than normal battery drain, try the following:
Charge the phone to full battery; let it keep charging until the battery says it is fully charged. Do not just wait until the light is green, it isn't always fully charged, causing a lot of inaccuracies. (You can check by going to: Settings -> About Phone -> Status -> Battery Level = Full.)
Boot to recovery mode and go to console (or adb shell) and type:
mount -a
rm /data/system/batterystats.bin
NOTE: Newer Amon_Ra and ClockworkMod recoveries have an option to delete the battery stats, do this in place of the console commands above.
NOTE: To have the most accurate of battery stats, reboot the phone immediately after wiping the battery stats and wait for CM to boot completely to the desktop. Once your entire boot is done and you have full access to the phone, go ahead and pull the charger and continue with this troubleshooter.
Do not charge the phone until after draining the battery completely, resulting in it automatically shutting off.
Recharge the phone completely and then use as you normally would."

I've wondered this -- what does the conditioning actually "fix"? (I understand it doesn't affect the way the battery physically charges & drains.) Is the problem (pre-reconditioning) that the phone is thinking/saying it's fully charged when it's not, and so you're not starting off with the 100% charge you thought you were? Or is the problem that the phone thinks (and represents) that the battery is discharging faster than it really is, as you use it? Or something else?
Also, I've read others on here talk of allowing the battery to completely discharge, and then charging to 100%, ~1x per month -- without any talk of "wiping stats." Is that supposed to be something different altogether? Thx
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

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?

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.

when it is at 0ma then reboot into cwm and wipe battery stats?

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?

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.
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

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.

Apparently wiping battery stats doesn't do anything at all, it only wipes the actual history of battery usage, the same you see when you go to the menu and click the battery.
The whole subject is really a lot of speculation that as there doesn't seem to be a definite answer to calibrating the battery.
What seems to work for me and what seems to be advised more often is to fully discharge the phone, by normal usage then leaving it charging through the night, repeat the process the next day. When doing this process don't charge it in the middle of battery, you must wait until it dies.

@Mottz is right. Wiping that file only removes the history of what app used how many percent of the battery. This has been confirmed by a Google engineer.

Unfortunately this didn't work for me. I tried charging through the night and then discharging it completely and charging it completely again. I also tried deleting the batterystats file (even though I know it doesn't do anything)
So what do you suggest I should do? Get the phone replaced or get the battery changed?
I live in India and the phone is from Canada, so replacing the phone will take some time but I can get the battery replaced for around $20
