Why in the world don't you charge properly the battery before rebooting the device ?
My HD always reports the right battery values because I don't let the battery drain that much, if you wan't the battery to last many months please don't let it drain so close to 30%.

Because I want to test the battery consumption of HD .
Perform a complete discharge, recharge fully and then test..

Also some of us have no choice,
My device never lasts a whole day,
The battery consumption on the device is very bad.

You should say: some applications I installed or functionality I have enabled are draining my battery badly. The device itself with the standard applications does not drain the battery in one day.
I agree that for example using wifi is a major drainer, but I do not beleive there are other devices out there that do it a lot better, like say continous wifi for two days...
Battery cosumption is always a problem in all devices. There is no single PDA out there that does not have a "battery" thread and how bad it is blah blah blah...
I can give you examples of devices that will be drained within a couple of hours, and the same devices being able to last for three weeks or more. It all depends on what you run and how you use it.
Your may be right or maybe not,
I think I'll un-install my apps and reinstall again with each new app being added one day at a time, to work out if any of them is killing my battery

A "normal" application doesn't drain your battery. By a "normal" application I mean something that you open, work on, and close it again.
You have to pay attention to applications, which are running in the background and/or are polling every few seconds something.

Hi,
the battery took long to reach 50%... about a day of heavy usage but after 50%, it took less den an hour of heavy usage to get to 10%. anyone experience this? or is my battery fautly? thanks.
i know that between soft resets my battery will change values, usually go up e.g. if its 40% when i reset when it reboots it will be 44%
i have the same issue here
but the battery last 2 days with me

Same here...on my device from 50 to 10% goes WAY faster than from 100 to 50%. To me it means crappy indicator. Must be a HTC problem, as my Prophet displayed similar behaviour.
This behaviour ("jumping" percentage after power-off) is completely normal, but the explanation would be very long.
Short version: What the battery % displays is in fact a translation of the voltage of the LiIon battery. When you switch off the device the voltage recovers a little bit, thus you get a higher % value when you switch it on the next time .. and which will fall rather rapidly until it stabilizes under the present load of the battery. Also the discharge curve of a LiIon battery is not completely linear.

I followed directions on what I thought to be a battery fix, but it ended up making my battery life twice as bad. Actually it takes longer to charge now than it does to drain.
Anyone else have this happen?

I did the same thing, but I've only charged once and I didn't time it. I haven't been timing any of my charges or discharges, but maybe give it some more time, that's kind of how stats work isn't it....usage over time? Good luck.
Today I started at 100% (not a powered off full charge though). After 2 hours of moderate use I was down to 50%. I have been charging for an hour via car charger and currently at 67%.

Not to be a dink, but then it would appear that you didn't follow the instructions. As a result, YMMV I guess.
1. You will need to charge the phone to 100% (while the phone is off).
2. Leave charging cable plugged in.
3. Boot into recovery and wipe the battery stats (should be under Advanced).
4. Then boot into Android.
5. Then remove the charging cable.

Give it another shot, and I would suggest that maybe it not be thought of as a "fix". Try using the wall charger as well. I only use the wall charger as I have a converter in my vehicles. Let us know how it goes!

Those are actually the directions that I followed yesterday afternoon. I didn't notice the battery life being any different after doing that initially. At the end of the day I charged my phone via wall charger for roughly 8 hours while I slept.
I was unplugged for less than two hours and watched it drop down 50%. Wifi was off, Gps also off. I was doing some web browsing and also using the xda app. I played a game for a couple of minutes.. That was it. I really should've checked the battery usage but I didn't think of it in time.
I only charged it in the car today out of necessity because of the super quick discharge. When I'm at home I only charge with the wall charger.

I've heard others say they found facebook or twitter running in the background and that when they killed that it made a big difference in battery life. Perhaps that?
WiFi set to never turn off
I noticed this morning that WiFi had been set to never sleep, I just changed that t 15 min.
Had a full 100% charge last night did not leave on the charger, minimal use this morning down to 78%.
Let's see how the new WiFi settings works.

that doesn't do anything unless you leave wifi on all the time, and if you do then that would be one solution to this problem.

I experienced the exact same issue after doing the battery thing yesterday. Tried several different kernals since then - no change: I could just about watch the battery go down. This morning I wiped and loaded SR Sense 2.5.2 and the updated stock kernal from ROM manager. We'll see how it goes...

I did this and just installed 2.5.2. I then installed the Hydra kernel and wiped battery stats when I was at 100% and the unit was off/green light. The battery has gone to crap too. Any ideas?
thats weird, i did wipe battery stats (correctly) at 11 last night. i woke up at 9:30 (lol) with 93% battery left. the phone was sleeping the whole time, but i had sync turned on and had recieved several facebook updates, txts, and emails. now im losing around 10%battery every two hours or so, and i am using the phone to send txts and emails every three to five minutes. so battery life is actually much better. after the cable is unplugged, is it necessary to let the battery die fully, then charge, or can i charge it now? (its at around 30%)
so basically, i was wondering if it is necessary to run your battery fully down after doing a wipe battery stats
I don't know what to tell you guys. Since wiping stats, my phone has been up for 36 consecutive hours with an awake time of 2:40 and the battery is at 30%.
For reference I guess....

It's completely impossible for wiping your battery stats to make your battery life worse. It's a common misconception that by wiping your battery stats you somehow condition your battery. It's actually quite the opposite, because you're actually conditioning Android by wiping your stats. No matter what your battery percentage or meter says, your battery is still capable of holding a certain amount of electrical charge and your phone will not die until it's fully discharged. On the other hand it *might* make your percentage or battery meter read wrong if you either:
a. wiped your battery stats without a full bump charge (e.g. wiping your stats at 60% charge *might* make your phone think 60%=100% and as a result, you'd see huge decreases. but, you would most likely sit there with a phone showing a 1% charge for hours after it got there.)
b: didn't allow your phone to discharge fully after wiping your stats (same problem as example a, but the inverse of it)
All wiping your battery stats does is delete the file "batterystats.bin" from your /data/system folder. This file is recreated when you boot your phone after wiping them. It keeps the data on what's using your battery for when you click "battery use" in the settings menu. It's also thought to hold the stats that tell you phone what a full charge and no charge feels like and that if you fully bump charge your phone, wipe that battery stats, and then full discharge your phone (without interrupting it by switching ROMs or doing updates) that you will have a more accurate battery meter. It won't eliminate the need to bump charge your phone or make your battery life better. It will just be perceived as better since you won't get 20% drops in your reading in 30 minutes due to a badly calibrated batterystats.bin file. Also, you'll feel better because instead of looking at a 50% reading, you'll be looking at 60%.
Your battery still has the same capacity, charges to the same level, and discharges in the same amount of time. The only thing that can change those things are usage levels.
so should i redo my wipe battery stats then? when i originally did it, i ran it down to around 40%, then rebooted, then i plugged it in around 15%. would this mess it up then?

Do you know how we can see what's inside the actual batterystats.bin file? I tried in root explorer and cannot open in no matter how I try.
i dont care what vantagejuan says, when i tried this process...and did it correctly, my battery was down to 85% within an hour..i know this because i unplugged it when i woke up for work, and i when i clocked in, it was at 85%
it was never this bad, i tried locating the file again from an old backup, but it didnt help...im hoping that like someone else said, a couple cycles through it will get better
im using the skyraider 2.5.2 vanilla with the hydra oc/uv kernal
i had this setup before AND after trying the battery fix and im using the seidio 1750...

Hi guys,
I'd gladly post this on the CM7 RC's thread over at the dev forum but I have yet to accumulate 10 posts.
Lately I've been experiencing weird battery % issues in CM7RC2 and now CM7RC4, that the charging would be stuck at a certain percentage even if I charged it overnight. It never goes to full, until I pulled the battery and rebooted.
Is something wrong with my battery?
Thanks in advanced!
Are you using an official battery or a third-party battery?
I'm using the official one

First, doing the battery drain is effective in calibrating the battery meter but is still probably a bad idea because by doing it you are decreasing how much charge the battery can hold (i.e., a full charge will not last as long). It might not be super noticeable, and doing it once in a blue moon is likely not a big deal, but don't do it often or you'll just end up having to replace your battery. Deleting battery stats should be enough to correct the OP's problem, and allowing your phone to recalibrate under normal use is fine but takes longer.
That said, I do the battery drain anyway, but I would definitely suggest not doing it more than once every 6+ months. Wiping battery stats often is not necessary at all, unless of course you are actually having a problem like the OP is.
Second, you definitely should not clear battery stats AFTER performing a battery drain and recharge. The whole point of doing the battery drain is to let the phone gather new information about the battery since you just wiped the battery stats. If you wipe them again after doing that, the battery drain was useless.
As of Saturday evening, my phone will no longer charge past 88%. Earlier on Saturday, the phone was charged to 100% in my car. We lost power and the phone ran down to 3% before I was able to charge it again.
After charging over 8 hours, the phone would not go past 88%. Any ideas?

Charge to 88% or until you notice it not going any further. Turn off the phone. Plug in the charger and wait until the battery display shows. While the phone is still plugged in, remove the battery. Wait for it to boot up and show a no battery icon (or something like that). Once it does, put the battery back in and leave it for about 30 mins. When you hit the volume buttons, the display will show between 5-10% charged. Anyway, after about 30 mins, turn the phone one and it should show 100%. Re-calibrate the battery after that using the app or recovery.
Are all android batteries like this? I've never had a device with such finicky battery stats. I too have the 88% problem and i feel like im recalibrating every week. I will try again.

I don't think they're all like this..but I know its as annoying as F***. Every morning almost i'm doing the "battery pop out" trick just so that it'll read full. It would be different if it read 95% or something and stuck there for awhile until the battery caught up to the actual reading..but it doesn't. The battery continues to drain at a normal rate, so you basically lose however many % you had initially.
Definately annoying..

do you have the same battery issues on your galaxy?
So I've been sitting at 1% for the past hour. Been playing games, have wifi, bluetooth, GPS all turned on.
Thing will just not turn off!
EDIT: Right as soon as I post this, it turns off. Over 1 hour on 1%.
Will recharge tonight and hopefully it works right.
I had this problem for a while but you should know that it will fix itself eventually. The phone is fully capable of re-learning the limits of the battery and after several days will begin to display the correct charging status. Mine took about a week to start displaying 99% in the morning.
This happened after I did the complete discharge, charge, pull battery, charge again, then boot procedure. It was fine for a couple of days then started displaying 82% as a full charge then slowly got better. I'm fairly confident that I'm not leaving anything on the table in terms of capacity either since with moderate use and turning off wifi when I leave the house I'm getting about two days of charge.

When I turn it back on, it says 2%-3%. It then shuts itself off again, I plug it in and turn it on...says anything from 3% to 90%.
I've always ran the battery down and charged to full. Is my battery kaput? Is there a way to fix this?

Most likely.. take out the battery and inspect for leaks(might be very small discharge you might not see it clearly leak can and will damage your phone)..let it die completely, and let it stay off, charge it till the green light comes on, reboot into recovery, clear battery stats, reboot and see how long it last, also change your brightness, and other settings that might be consuming battery use..if none of these helps.. just buy another battery.
Sounds like your battery is screwed. Just buy a oem battery or get a mugen power 1650mAh

My issues aren't quite that bad, but after I upgraded to CM7.1 from 7.0, by battery has been terrible. 15-20m of phone calls over BT takes ~20% of the battery. 15m on Angry Birds chewed up ~40% of the battery. I downloaded the latest nightly (252) and will see what happens.
Try a dif battery and see if it does the same thing. So you can rule things out

Mines also been horrible since I went from CM 7.0 to CM 7.1. Not sure whats up but it dies in like 6 hours on standby. the battery use app shows that most of the battery usage is by "Cell Standby". So effectively, doing 'nothing' is eating up the battery?

I guess I'm not having the problem you guys are having with battery drain. Granted I didnt use my phone that heavily, but still sitting at 60% after 10 hours. But if your battery is dead after 3 minutes something is seriously wrong, I agree and try a new battery.

You need to calibrate the battery after changing ROM's. Download a battery calibrator from the market. (Don't pay for one. There are like 10 free ones)
Charge the phone fully overnight. Calibrate it in the morning.
Give it a few days to gather new battery data, and then enjoy getting a full day's use from the phone.
Update
So, it's gonna have to be the battery. Recalibrated, no good. Tried a few different ROMs from CM7 nightlies to MIUI, no good.
Waiting for the new battery to get here to be sure.
Thanks for all of the help and advice!
same problem here
hello there, i got 2 mytouch 4g both running the same rom (virtuous unity 2.39) one of them has eaten 2 batteries that i bought thinking that the batteries were somehow broken or damaged... i came across this thread, read the reply recomending battery calibrator when i reached for my phone (that i left sitting on my drawer waiting for a new batt AGAIN) to give it a try and to my surprise it was still on and i has been on for 2 days 11hours and the fricking battery was at 97% before that it started to turn off-discharge so i put the thing on airplane mode and there it was till now... dunno why or what but i think it has something to do with the radio/network... hope we find a cure for this
I've been having this same issue, and I was wondering if replacing the battery fixed the issue? Thanks.
