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

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.

Er, if you wipe the stats, won't it "forget" the draining and charging you did first, making them pointless?

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.

"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

Sorry if this is a dumb question (I don't own an Epic 4G, I'm asking for two members of my family who do), but how do you wipe battery stats? Do you have to be rooted to do that?
I've seen 25 hours without calibration.
Both Epics in my family are only getting a few hours out of their batteries, even with no use, and they used to get very good battery life, which leads me to believe that it's a calibration thing, but they're not rooted and I can't find any way to wipe the battery stats on their phones.
Can anyone help me?

I wish they would build such a calibration function into the OS, so it could be done without rooting. Meanwhile, the only way I know of for a non-rooted user to wipe the old battery stats is to do a factory reset. But that means backing up and restoring apps and data.
Maybe an app on both stock Epics is running the battery down. Check Running services in settings>applications to see if there is something running on both. Sometimes it is an app trying to sync like Facebook, Oovoo or email. Set syncs for a hour or more. These are original stock batteries right?
Do you BONSAI?
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.

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?

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.

Hello,
I use Tytung's ICS 4.0.4 for my T-Mobile HTC HD2 (NAND), I've been using this ROM for months.
As such there is no problem with functioning of the ROM.
But my battery drains at a very fast rate. With 6hrs of use it drains to 20% at lowest brightness and no major applications running (2 applications in background at most).
Data enabled (2G).
What to do? Please help!!
Sent from my T-Mobile HTC HD2 using XDA Premium.
Can you download CurrentWidget from the Play store and give a value in mA? If you mean 6hrs without any usage then that's pretty poor. Try turning on airplane mode to determine whether it's an app or one of your connections that's causing the problem.
In currentwidget, the values should be approximately 4mA drain in standby with any connections enabled and 2mA in standby in airplane mode. Screen on drain varies a lot more.
OK, thanks. will revert back soon.
With screen OFF, networks ON, 2g enabled....drain is 6mA.
With screen OFF, airplane mode ...drain is 5mA.
Sent from my T-Mobile HTC HD2 using XDA Premium.
That's high but shouldn't be causing a drain of 20% in 6 hours. It's probably just draining a lot when you're using the phone, and there's not much you can do other than turning the brightness down which you've done already.
try wiping battery stats through recovery...fully charge your battery then wipe stats and let your battery to get fully discharge before you connect it to a charger for about a week...My battery never lasted more than a half day before doing this...now it lasts more than a day...Hope this works

I wonder if this myth will ever die..
Google engineer Dianne Hackberry has talked about several myths about the Android operating system, including wiping battery stats.
The reasoning behind that piece of advice was something like this: If you, at some point, did not charge your Android device fully (for example, only to 80%), it would supposedly remember that battery level as “fully charged” – in this case, you’d only ever get to use 80% of your battery, which is of course less than optimal. So, if you wipe the battery stats, usually done in ClockWord Mod Recovery, the device would “forget” the previous level, here 80%, and instead charge to the full 100% once again, thereby re-calibrating the battery. Or, as Hackborn puts it in more technical terms:
The battery indicator in the status/notification bar is a reflection of the batterystats.bin file in the data/system/ directory.
However, as she explains, that’s not the case. Because those battery stats, stored in the batterystats.bin file, are only used to maintain information about what is using the battery when not recharging. That is, it essentially holds the information displayed in the Settings > Battery screen. Nothing more, nothing less. Thus:
It has no impact on the current battery level shown to you.
It has no impact on your battery life.
What’s more, you’ve probably noticed that the battery usage data is reset once you recharge your device anyway. From this you can correctly deduce that the battery stats are wiped as well – every time your device is recharged. More or less every day. If there was any effect, you would’ve noticed it without going into recovery and doing that stuff. Typical placebo, eh?
---
I’m as confused as a baby in a topless bar...
^Whenever someone asks 'how do I reduce my battery drain', ten people immediately jump in with 'CALIBRATE!!11oneeleven!'. No hate directed at whoever posted that advice here, I understand how easy it is to be misinformed (as I was about using SetCPU ), I just think that rumours like this are too easily presented as facts.

Yeah Tasker can do this but it's a paid app. Juice Defender is free and can also do the same thing in this case. I agree that Tasker is awesome but not necessarily for saving battery, more for ease of use.

^Whenever someone asks 'how do I reduce my battery drain', ten people immediately jump in with 'CALIBRATE!!11oneeleven!'. No hate directed at whoever posted that advice here, I understand how easy it is to be misinformed (as I was about using SetCPU ), I just think that rumours like this are too easily presented as facts.

I have problem with battery status.I try delete file batterystats.bin in my data-system but not fix it.All version CWM not "wipe battery stats" line..Help me
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.

Hey, my device also shows incorrect battery %age. To fix that all I need to do is follow @Mottz's procedure, correct?

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

This does nothing for a lithium battery.
Except maybe kill it faster.
What exactly is your battery issue?
