I accidentally did a batt wipe of stats.. So now it's at 10% and stays there... the g/f has exact same phone (hero cdma).. If I put her battery in mine when its fully charged can I do batt wipe stats again in clockwork to get my battery working again??
Just let your phone die, and do a full charge and you should be fine

You can rebuild your stats simply by letting your phone die and then charging it to full a couple of times. You actually wipe your batt stats every time you wipe to flash a rom because they are stored on /data/
when it's plugged in I don't get the green status bar filling up like charging. Just stuck on a slight bit of green and the lightining symbol as charging.. gonna try letting it die and charge again like you said.. guess if all else fails i can try to use the g/f's battery later
Update... is charging and battery meter has went to full but not green led yet... Thank you guys. will try battery wipe stats after batt is fully charged
Phone is completely dead now... won't take a charge.. no amber light.. nothing.... gonna try g/f's batt later
Have you tried pulling your battery and putting it back in?
Wiping ths stats shouldn't cause that.

Oh yes.. multiple times.. Still to no avail... brand new battery too. got it from sprint yesterday.. First Hero I rooted i was stupid by flashing the radio and reboot too soon so it bricked it.. gave me a new phone with the old battery.. battery dies so I went back and got the good one.. now thats bad. I had put cm6.1 on when I got the new phone back.. had noticed the tech guy removed my backup of the stock rom.. he noticed that I had rooted it to cm6.1.. D/l'd the stock rom and backed that up too.. had been running 2.1 all since I got the phone
Update.. All is well again.. g/f got home and used her batt to fix my F ups.. wiped and wiped again then flashed to stock ROM.. will recalibrate with stock ROM and flash CM after batt issue is done and fully charged.. Must have flashed CM wrong or at the wrong time with my batt level..
Just an FYI, you need to calibrate with each ROM you flash, as the stats get wiped.

When charging the battery (after wiping battery stats and letting the phone battery discharge until phone shuts off) should you power the phone on after plugging it in or should you leave the phone powered off when fully recharging? Or does it not matter?
Let phone die
Charge to 100%
Boot to recovery
Wipe stats
Reboot while still plugged in
Unplug when phone is fully booted
Fully discharge and recharge a couple more times

So I was running cognition 2.4.1 for a long time, and my battery life was awesome. It would barely go down at all if I didn't use it, and would make it through the day with about half to spare. On normal days I unplug at 630am and at 5pm it would be at ~70% (if i didn't really use it at all). Even if I did use it it would still last a long time.
I finally decided to flash a new/different rom and thats where my problems started. I flashed Assonance 5.0 and the battery life got worse (at 5pm i was at about 45%) so i just assumed it was the rom and that cognition was better on battery life. So my next flash was back to cognition (a newer version, b7 i think), which improved battery life, but it was barely noticeable, and was no where near what it used to be. Next I tried pheonix v1.5 and that was probably the worst yet, as my phone almost died by 5 oclock.
Finally I decided I would go back to cog 2.4.1 even though it was outdated. I figured this would solve all my problems. I was wrong as my battery life is absolutely terrible right now. At one point yesterday it drained 12 percent in 30 mins.
Something else also happened yesterday. As it was almost going to die i plugged it into my car charger for about 10 mins. It was at 15% when i put it on and 19 when i took it off. After that my battery life was almost normal again as it only drained 4 percent over the next 3 hours. Later on that night I charged it back up to 50 percent and about 10 mins after taking it off the charger it said it was at 5 percent. It stayed at 5 percent for the rest of the night and did not die ( about 4 hours).
Theres definitely a problem and I know it was to do with the battery reading. I think i just need to reset the battery stats.
FYI every time i flash a new rom i always flash back to stock jf6, make sure its 100% battery, wipe data and cache, etc etc etc. so im not sure why this is happening.
I also tried wiping stats through clockworkmod recovery, but i dont think it really does anything.
The proper way to wipe battery stats/recalibrate your battery:
Charge up to 100% with the phone on. Disconnect the charger and turn the phone off. Connect the charger; you're now in charge mode. Charge up to 100%, disconnect the charger and turn on the phone. As soon as the phone is on, turn it off. Connect the charger to put it into charge mode again, and charge up to 100% again. Some people also say that before starting this process it's a good idea to kill the battery completely.
That is how you bump charge, or recalibrate the battery. After bump charging is the best time to wipe battery stats.
I can't find batterystats.bin on the phone to delete it. Is the only way via terminal mode or Clockwork?
Is it true that the porcentage of battery u have when u flash ur phone is the one that will be used as the new 100% ? also whats the procedure i should use to erase the battery stats? my phone dies in like 4 hours , let it discharge, charge completely and then?
I don't think so, cause i always flash my MS anytime i wish even when the indicator show <20%, or when charging on UBS
I also never bothered to charge fully before flashing. Though I think resetting battery stats does help indeed.
i also read something similar to this, someone told me to charge to full, then let the phone discharge UNTIL IT TURNS OFF BY ITSELF (=battery completely dead), then charge to full again and then delete the file batterystats.bin in /data/system folder (root required).
i suppose this is what you are talking about?
i will try this in a few hours (currently discharging the last % of my battery).

Im confused im supposed era the stats before right after chanrging full charging the phone or i sould let it discharge m, then erase the stast and then full charge the phone?
What's your ROM?
On froyomod do you have option to calibrate battery and wipe battery status
Well, I've flashed it to FroyoRom with approx. 40% charge, played around a little, the next day when I was normally using it and my battery went down to 30% I deleted the battery stats, the system rebooted and voilla, I was at 50%
I don't know about this full charge - discharge - full charge - delete stats version. I guess I'll try it on an occasion and see what happens. At this moment I'm at 90% after being disconnected from charger for 5 hrs, though I wasn't using the phone much during this time.
...and currently finishing the same charge - after 1 day and 17 hrs currently at 20%. My Milestone never made it through the day without having to charge it through the night. Love it
The FroyoMod is really the best at the moment...
I never had this problem until recently i've flashed to Cog 4.
It started after i did a full charge. It discharges to 80% and to 50% and to 20% and to 5% and then died off within an hour. My phone heated up even though when it is not active.
Now, after changing a new battery. I find that i can't charge it above 85%. I re-flashed with Phoenix and Serendipity. The maximum charge still stays at 85%.
I've cleared the battery stats and nothing changed. I need help here.

It has some discussion about cog and battery life, but I suspect it might be outdated. Either way, it should have good info for you on how to get the battery fully charged
First of all, with custom roms, battery drains much quicker than normal, but i think you need to do a calibration. Charge your phone for like 12 hours to make sure its completely full, then drain it all the way until it dies. Then make sure its completely dead and wont turn on (sometimes the phone thinks the battery is dead, but its not. To solve turn on and off until there is no more responce. Take out battery, then try and power on. This will get rid of any static charge in the phone. Put battery back in and charge for another 12-15 hours to make sure its completely full. Go into recovery and wipe battery stats. Then let it die. That should do it.

yes and no.
custom roms wont necessarily use more power, in most cases less. and technically most power consumption is controlled by the kernel, and secondly the installed services in the ROM. new kernels useually come with a new rom but you dont have to keep it or you can upgrade it ect. But yes, when changing the kernel either by itself or with a rom you should reset battery stats.
I suggest drain it dead, plug it in until it is full, reboot into recovery and wipe batt stats (or use SGS tool script) WHILE PLUGGED IN, unplug.
or if you have an external batt charger, wipe batt stats in CWM then put in full battery.

When I said custom roms i meant that when you are on something other from stock. And for the most part, unless you are on a minimalistic rom, you do get worse battery. It is a known fact. Sure I have gotten 50 hours out of a rom/kernel combination, but it was never consistent. I had to flash back to stock and masterclear because i have random shutoffs and need to return it, and im seeing easily 30 hours out of stock with 3 hours usage of web email phone. Maybe its not the same for you, but stock has had the best consistent battery life for me.

So I bought a brand new battery off ebay, wiped the battery stats and everything else on the phone and I installed a new ROM.
I followed Cyanogen's Wiki battery wipe procedure.
My problem is that when I get to the last step the battery doesn't seem to recharge to 100% even when left overnight; but if I reboot it it will go to 99.9% then 100%
Is this normal for a new battery?
i think the proper way to charge a new battery is to keep the device off and let it fully charge, than turn it on..? maybe.. im not 100% sure lol

dont know if anyone had that issue but i did too. best way is charge the phone to 100%, leave it plugged still boot to recovery, wipe stats, reboot, let it sit for a couple of minutes then you can unplug. or download this app Battery Calibration and when your phone is fully charged, just open the app, calibrate the battery, unplug and go
ps the G1's battery sucks monkey balls, but if you find a stable and decent rom/kernal, itll last you a whole work day with minimum usage, and having data off
NC battery can be charged, the indicator will turn green, the use of normal, NC battery has been displayed 11%,How to make the battery indicator to 100%？

Try rebooting into recovery and under advanced reset battery stats.

i also have this issue, but stuck at 31%. nothing works... tried clearing nc batt stats, manually deleting the batt stat file, and the app which doesn't work since its waiting for batt to hit 100% and forcing it does nothing too.

I had this same issue. I tried every app suggestion I could find online and even cleared the battery stats in recovery, but had no luck.
Eventually I think I had an OTA update break my root so I had an excuse to do a system wipe/update (from 1.2 to 1.3 I think it was) and while I was in clockwork mod recovery I did a complete system wipe (format everything, restored to 1.0.0) and reset the battery stats. When I finished the manual update to 1.3 and rooted, the problem had gone away.
I'm currently running eyeballer's CM9 nightly and have had no further problems with the battery indicator.
