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?
Sent from my SGH-T959 using XDA App

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

Anyway to fix this? Should i fully charge then wipe?

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

Recalibrating phone-

Should I recalibrate my phone? Will the battery get better?
I read about this and it says the battery will get more life if I Cali rate it by turning everything on to use battery and after phone dies charge it while its turned off and repeat process one more time...
Is that how it works?
I tried searching for recalibrate or calibrate but only threads about roms come up
Sent from my SGH-T959 using XDA App

Supposedly.
Personally and I mean personally. I do the following.
1) Use it
2) Turn it off at night when I sleep
3) Charge it over night
4) Turn on and no matter what it says leave it plugged in and charging
5) Remove from charger after 15 or so minutes of running while on/plugged in
6) Repeat Step 1-5
The reason I do that is simple. After flashing a Rom I notice when I turn it on it will say 97% or something odd like that. I let it sit and charge anyways. I'm not 100% sure if its really charging or if the OS/Battery is catching up with each other.
I've done what I mentioned up above with every android phone and every Rom and I've never done the Calibrate thing and I've had awesome battery life and I have no reason to believe that my battery/Os needs to be calibrated any other way.
If you or anybody is one of the few that leave their phones on why they sleep I have no idea or recommendations personally.

Yeah I leave it on but charging at night. Ill follow what you said I wanna know because people tell me its important to Calibrate it a month or so.
Also can you tell me if its alright to leave the charger on my phone while the phones on too during night? Or should I turn phone off? Why?
Thanks for replying
Sent from my SGH-T959 using XDA App

The reason why your both getting these 98 97 % is because you haven't calibrated the battery to the rom its important to do this because the rom will read the battery percentage very accurately.
So here's what you do:
1. Charge battery fully, which means if the phone says 100% let it charge for about another hour or 2
2. Now reboot into recovery (CWM Recovery)
3. Go to advanced and wipe battery stats
4. Now reboot
5. Disconnect phone from charger
6. Drain your battery till the phone shuts off on its own.
7. Leave phone off and charge till at 100%
8. Turn on your phone disconnect from charger
9. Enjoy.

[Q] How to calibrate battery empty point?

I've already wiped battery stats, I think I'm getting full charge, and I'm getting pretty good battery life (over 24 hours last run).
The problem is that Android can't seem to tell the appropriate 0% battery point. Several times I've had the phone shut down when the battery life is at approximately 20%. When I try to reboot, there is not enough juice left to make it even to the multi-boot loader.
Is there a way to recalibrate the dead battery point so Android reads correctly?
BTW, I'm running Darkstone SuperRAM Froyo 1.5. (SD/RAM build)

have you tried turning off the phone and let it charge to 100%(when you dee the green notifiationled) and then turning it on. and then wipe the battstat.
just an idea, always used this method if the phone cant charge past 99%, maybe it wil work to on the dead point.

Yes, that's how I wiped the batt stats the first time, which greatly improved battery life. But now there is the power off at 20% thing. Strange.

Then its the roms fault some things are just the way they are. Mine goes to 15% and shuts down. The build I'm now using goes to 8-7% with 100% charge. What Rom u using?

Oeps, you're running syperram I see I had that same problem with superram. I just live with it try nand roms!
Sent from my HTC HD2 using XDA App

i think it's the build's fault. me and a fellow xda user also experienced the same thing with superram.

Thanks for your help! Guess I can stop searching in vain for a fix. I love the build otherwise - the only one that hasn't given me sleep of death with TMOUS.
Unfortunately I can't go NAND yet due to a crappy WM application I need to use for work, which isn't available in android.

See if "Tasker" app can do an auto shutdown at 20% and keep a spare battery in the pocket if you like SuperRam. I like SuperRam and it's my build of choice. Not a fix, but a spare battery in the pocket is good anyways.

Extreme Battery Level Drop After Reboot, Increases During Use

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

i have been using pure stock rom by wannam but rooted for the past week with 12 hours aday syncing and surfing the net and plenty of voice calls via viber and my battery lasts at least 16 to 18 hours.
right now i am using odexed KL3 Kernel KL2Base KL1modem 2.3.6 and it is absolutely amazing interms of battery life and performance.

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.

I am not an expert but i think you can do this....
1. Clear your batter stat
2. Drain your phones battery completely
3. Recharge your phone to 100% while it is switched off. (this might take 2 hours i think)
4. Once it is completely recharged....then use any battery calibration application and calibrate it while it is 100% charged.
I hope this works, else you will need to find some battery fix for this problem
Thanks.

Maybe u hav a defective battery mate. Try another battery, see if u still got 80%.
