Hi!
Yesterday when my battery was at 88%, I wiped the batt stats from Amon Ra.
When I switched on my phone, my hero told me that the battery was full (100%).
I want to know something more about Recalibration of the battery by wiping battery stats. Searching on the Internet somebody tells that is important to wipe batt stats when the battery is empty, and then charge it.
Other people reccomend to wipe battery stats when the battery is full.
What do you suggest?
Thanks

The way I've learned to recalibrate the battery is to let it go down to 5%, boot phone into recovery and wipe batterystats, then power off the phone. Let the phone charge until the green led is on without turning it on. Then turn on and use the phone as usual. Learned it over at modaco. Worked as a charm, and batterytime was improved. I have personally experienced strange batterybehaviour after periods with flashing a lot of roms.

Yep, every time I flash a ROM it's suggested to do a full wipe, battery stats also, and i think that with a lot of flashing, the battery behavour become strange.
I tried that "trick" today on my phone, I will tell you how is battery life.
Thank you!

No problem! Good luck
I'm going to try this tonight and will report back my findings tomorrow.
I just hope I don't get any important calls or texts while it's turned off to charge
Any update on your experiments guys as I am about to do the battery stats wipe too.
Any updates on this?
Ooops, I forgot to reply back but it's been covered in different threads in the Hero section and for other Android phones... it does work.
As others have said, after flashing different ROMs the battery starts to mis-report but this trick seems to sort it out

Yesterday, I let my battery die. Charged it last night, and wiped battery states. Ran the phone like normal today. Was down to about 30% left, rebooted. When everything came back up and running, that battery showed to be 5%. WTF!!! How do I drop 25%, just by rebooting?!?!?!?

So...I should wipe the battery stats again after re-charging to 100%?
Then wipe the battery stats in advanced of recovery mode

I re-wiped the battery stat this morning. I was down to about 50% when I needed to reboot. When everything came back up, it showed I was down to 28%. Is this an indication that the battery needs to be replaced or should I try a different Kernel?
Either you have a bad battery, bad battery meter, or your not reconditioning right.

What would you suggest I try? What is the proper way to recondition my battery?
Charge to 100%
Boot into recovery
Wipe battery stats
Reboot
Don't unplug charger until at desktop again (You could debate this one, but that's when I do it)
And don't worry about killing your battery, it'll do more harm than good.
Explanation - When you wipe battery stats, it tells your phone you're at 100%
So, if you wipe when you ARE at 100% you'll get accurate readings.

The past 2 times I did this, the phone was turned off and plugged in and charged over night. this morning I wiped the stat, but i do not remember if I had unplugged it before it finished booting up. I am charging it now, with it on. When it reaches 100%, should I reboot into recovery and wipe it or should I let it run all the way down?
What exactly do you mean by 'let it run all the way down'?

Down to say some were around 20 - 5%.
As far as I understand that shouldn't be necessary, and could weaken your battery.
As long as it's fully charged when you wipe the stats you should be good to go.

Ok...I have ran the phone like normal. Within 6 hours, I am down to 62%. I rebooted the phone, and it still shows me at 62%. At least I have that fixed.
Now, I see some people use OverStock and seem to be getting better battery life. I just want to get about 16+ hours out of my battery. Right now i seem to be pushing 12 hours. What is the tick that i am missing??
For every hundred vibrant users there seems to be a hundred different accounts of battery life, and a hindered different opinions on how to keep it down. 12 hours on the stock battery is pretty good, especially compared to stock.
Mine'll last me around 15+, if I left it not charging, i think.
I'm on overstock, the screen is at the dimmest 95% of the time, and I use setcpu. 1000/1000 with a screen off profile of 200/200. So, that works for me pretty well.

You need to recondition yr battery as posted above, 2-4 cycles. But i prefer to re-flash ROM when battery 100%, should you get proper batt stats.
You may buy new one to test yr system n batt stats, also good for spare. Or just borrow yr friends battery, just to check yr rom n batt stats. Treat it like you did before.
Good luck.

200/200 conservative scaling and no sleep death? Didn't know that was possible on overstock...guess I'll try it.
Edit: sleep of death...you must be on power save or something which afaik doesn't work at all.
*checks*
Yeah, powersave. What's this about it not working? It occasionally lags a little when I unlock it and the widget definitely says 200
Sent via telepathy
I don't think powersave is supported...try conservative and you'll get sleep death due to the low frequency...you don't get this with powersave because I don't believe it's working...trying to confirm this.
Hi all!
I recently flashed Trigger + Overstock. The problem is related to battery drain. I am trying to re-condition the battery/wipe battery stats...However, My battery will not charge to 100%. It stays at 99%. I assume this isn't normal. Wondering if anyone else has come across this before?
Any ideas? Or can someone point me in the correct direction to fixing this?
Thanks!
My devices usually stay at 97% no matter how long I charge it.. Sidekick 2008, iPod Touch, Vibrant, even my computer.
I'm not sure why.
Yeah...it's just weird. I mean it used to charge all the way up to 100% and even notify me that it was completely charged before I flashed it.
By no means am I complaining about it. I just was wondering if that was normal after a flash. Also, more importantly will re-conditioning of the battery still have the same effect even though it's not at 100%? That's my real concern to get good battery life without going back to stock.
Thanks!
I had the same issue for awhile and honestly it seemed to more or less resolve itself after a few charges. I don't know if that was just my experience of the ROM updating the battery stats.
Have you fully charged the battery and wiped the battery stats? Even after doing so, it may take a few charges for the ROM to fully recognize the proper battery levels.

Yeah, I fully charged it...well to 99%. Then wiped battery stats. Hopefully like you said it will correct itself after a few charges.
In regards to wiping the battery stats, did you use root explorer and delete the batterystats.bin file in the system folder or did you try to wipe the via the CW Recovery menu? I personally never had much luck doing it through the menu.
I see alot of people are doing this after flashing Das Bamf
I did after installing 1.3, and it just seemed to make my battery drop like crazy, and then at times, not drop at all. I just installed 1.3.1. so should i do a battery stat wipe? what purpose would this serve?
I am not sure the "best practice" on wiping battery stats. I was always under the impression that you should charge to 100%, wipe stats, and then leave on charger until the battery is at 100%.
Not sure if it is best to then do a complete discharge cycle before putting the device back on the charger. I really do not know what the battery stats includes. I always thought it contained battery calibration data.
I'd really like to know this as well.

I think thats what it contains as well, however should i be plugged in while wiping? I always go to the battery stat menu in CWM, then right before i hit Yes, i unplug
I also read the same the thread (got the same rumor), after two battery wipes and fresh rom flashes (from 100%), in either case (on both VIRUS and BAMF) my battery mysteriously goes back to 86%. I can charge it back to 100% again but kinda thinking I shouldn't of wiped it. That or I'm doing it wrong.

Mine does the same thing!! Well, 87%, lol i think maybe our phones are saying 100 when in reality its 86 or 87? also got to keep in mind that rebooting afterwards drains battery like crazy.
Try "bumping" the battery, search battery bump to see the steps, mine use to do the same thing, from 100 to 93 after reboot, now stays in 100.

should i wipe battery stats i switching from extend. battery to stock. or only when switching roms? when does this matter?
[Also i know this doesn't belong here but my PC is really slow do easiest way is to ask: is there someway to search all my posts at once as they're becoming hard to keep track of ?]

I switched back to my stock battery after my extended died. I wiped battery stats, wiping stats when flashing new roms is recommended.
Wiping battery stats is never really considered an essential thing to do no matter what. It is nice though to do. I suggest it when you start realizing crap battery life on one ROM/kernel compared to the last one. The suggested way is to wipe it after installing a new kernel and as well as when you swap batteries. Other than that, really no need to in my eyes.
I wipe after every new ROM install, period.

This is when I do it also.
Digging up a thread here, didn't want to waste a new one.. But I have the OEM Extended Battery and I tried wiping my battery stats.. Charge full, reboot into recovery, wipe stats, unplug.. After this I noticed that my battery said 93% even tho the charge light was green.. I drained it until it turned off and charged again overnight.. In the AM, light was green, i turned phone on and its still showing 93% even though it was green. Any ideas? Did I lose that 7% forever?
Sometimes wiping the stats causes a bad battery read. A few reboots should get you back on track. If that doesn't work, try a full battery drain then a full charge. Let us know.
Will try that, even tho I kinda did already. I'm hoping with a few battery cycles the problem goes away.. What Im hoping is I don't need to bump charge now every time like I did when I had my inc

I doubt you lost anything. It would be like Spinal Tap having an amp which only went to 9.
I only had to wipe when my battery wasn't decreasing in percentage. After I wiped, it started decreasing like it should. I would think any fast reduction in percentage would be a bad battery.
Are there any proven facts out there that it is really ever necessary to wipe them? It's not like it actually improves battery life am I correct?
as far as wiping battery stats goes.
i have only used it when reconditioning a battery.
ie if you start noticing bad (read: worse that you have been getting) battery life after flashing a new rom or kernel. or just after a time using a standard rom.
what i do is
1 turn the phone off.
2 charge it on AC until it goes green and for an hour afterward.
3 unplug it and wait 30 seconds.
4 plug it back in and repeat step 3 until the light goes from red to green within 20 or so seconds. (this is called bump charging)
5 boot into CWR and wipe battery stats. and let it burn all the way down until it wont even turn on (flashing orange led)
6 charge to full and enjoy your maybe improved battery life.
when wiping battery stats, do i have to do it a few times or no? i wiped battery stats at full and drained battery until it turned off twice.. once wiping the stats with CWR and once, and after a cycle, with the 'battery calibrate' app (made by someone here on xda i believe)..
seems to be working okay i guess, but lets say i have 94%, i reset my phone and it comes back with only 84%.. it appears it's still reading my battery wrong by around 10%. is this normal?
It doesn't happen at every reset, looks like just the first one of the day. I guess I can charge to full, reboot, and charge to full again as a workaround.

i meant to ask this before but I forgot, can anyone try to do that and let me know if it happens to them too or if its just me
Charge with phone on until full then turn it off and charge.. about how long does it stay amber?

every time i charge my phone to full, the battery level reads that i'm at 91%, never at 100%. i deleted battery stats in recovery but the problem persists. i got an htc inspire and running absolution 3.7. how do i fix this?
my current absolution rom is a backup. i had 3 different roms before restoring this rom. should i have done a full wipe besfore restoring the rom? could this be the problem why my battery doenst give a good read?
How did you charged before wiping stats?
The best way:
- power off your phone completely
- charge battery
- wait till battery-LED is green (maybe just wait a little bit longer)
- start into recovery
- wipe battery stats

hi choliemelan.. to answer your question, i had my battery at 90% before wiping battery stats in recovery.
but i got a quesrtion for you.. my current rom is a backup of absolution. i had 3 different roms before restoring this rom. should i have done a full wipe before restoring the rom?

the 3 Roms you used before were Absolution, too, but different versions? So a full wipe is recommended, but shouldn't be essential.
In case of trying fully different Roms, a full wipe / factory reset is neccessary, also if you are using a "xyz"-Rom before and want to roll back to a backup of Absolution-Rom.
also your battery might have started to get weaker. if you use the phone a lot and make lots of charging cycles battery life gets shorter. also if you plug it for a minute or for an hour its considered a charging cycle. so if you have a lot, then you might have to get a new one

hi choliemelan.. actaully, i used 3 completely different roms, not different versions of Absolution, just to let you know. tell me what you think i should do.
Its not a strange problem man, google it, it happens all the time, just keep charging it properly and it will be fine. I wouldnt worry about it, some phones go to 100% and drop like a stone till 90% then go normal, its just the way your phone translates it
I had similiar problem...whenever i played games or anything that used 30% battery or battery was below 20% I pluged to charge but it stayed there for 1:30 hour 0o. So i unpluged and played games till 0% and phone "died". Than removed battery for 2 mins and charged to 100% without turning on...
when you use all of battery take battery out(i dont know why but it makes battery better). This battery in androids really mess up things...hope u fix it

yeah my battery today started off at 97& after full charge. then when i checked on it 6 hours later, it reads like it started at 100%.. this is very strange.
Kind of similar problem with me, Even after keeping my htc one v in charging for 4 hrs, the battery still reaches 85 ~ 90% always, and then it charges at snail's speed.
If i restart my phone at this point, the battery indicator shows 100% !
I am confused, since if it was a genuine trickle charge, the battery percentage should remain same even after reboot.
