i use htc extended battery on froyo 2.2 stock and kernel is 7.7 hasterin which support extended battery
problem is i have to pull out and then plug in battery to get the extended battery life... it drains like normal battery n then when i pull/push it in i get 50 percent more battery.. any fix for it?

I have the same problem with my batterry. The battery drains like original one. When i pull/push it again, about 50% remain in it. Im not found any decision until now.

I am looking for the name of the battery stats file and where it is located, on my installed rom Trigger. I updated this rom but my battery life is poor. On a older version it was great. Yes I wiped the battery stats after conditioning my battery. Many ppl have good life with the update so something is different with my setting or something. What I want to do is pull that file from my back up and put it on the new version. Back in the day of my Behold 2 I and many ppl put the batterystats.bin from BH-MAN aka "eugene373" phone to ours and my battery life increased 50 percent.
Is it necessary to calibrate after flashing a new kernel?
Not really. I found my battery life is better after I flashed the new voodoo kernel by jt. If you do have some bad battery life, it would be suggested you do calibrate your battery.
how do you calibrate your battery also i notice after i charge my battery all nite the next morning i start off with either 99 or 98 percent any reason why???
Calibration of the battery isn't really required if you flash at 100% each time.

This is expected behavior designed to protect the life of your battery. basically what happens is your phone will charge to 100%. It's not good for a li-on battery to stay at that stress level so the phone will then allow the battery to discharge to 95%. Once it hits 95% you will start charging back up to 100% and the process will repeat. If the phone didn't do this the battery would degrade much more rapidly.

hi.
I am using CM7 now which is great, but since I am going to a trip abroad I need to temporary change to a ROM with GPS, but most inportant, with a great battery life.
I don't need any great performance like CM7, I just need the battery to last long.
Any recommendations?
Thanks.

from my experience best battery i have on this rom i flashed this rom yesterday and charge it to 100% and run batt calibration it is preinstalled in this rom when you run batt calibration after that unplug your phone from charger and use it till total discharge and do not turn your phone on charge it to 100% again and its ok i've did it and play some games wi fi is enabled always i've use gps for 15 minutes and from yestarday till today so now i have 82% batt so i thing this is the best for batt
oh by the way lag fix is enabled to
Thank you. Do you know if calibrating the battery is useful even if I have one extra battery and I switch between the two batteries if necessery?
I don't know about the two battery thing, but i do agree that Project V have great battery life. Im using Super Dragon Modz kernel OCed to 1.3, and the phone its doing pretty nice till now. I unplugged it like 2 hours ago, and it still show 100%. On CM7, i would be around 75 to 80% by now. Battery life was the reason that i came back to Froyo.
WOW that's great battery life! Thanks a lot.
i don't konw about 2 batteries but calibrating is usefull it's helping 98% bug after unplug and it's greating a new battstat file what is realy nice project v6 is very good rom for battery i did't tried super dragon
I don't see how callibrating the battery helps extend battery life? The battery remains at the same capacity and draining any battery completely shortens the lifespan of the battery. I can see that the system might get a better prediction of battery life... But you get that regardless after using the phone for a few days / week...

I recently bought this battery: http://amzn.com/B002MRA8FQ
However, it doesn't seem to last longer at all compared to the stock battery. I thought that maybe I needed to drain it fully and then recharge it the whole way before it would work properly, but I noticed that it was reporting 1% life left for a good hour or so before I gave up trying to drain it. Is it possible that the battery life isn't being detected properly since its not the stock battery or is there something else going on that it lasts exactly as long as the stock battery?
as i read the article, it doesnt apear to be an original LG battery...did u ever thought that batteries are not all about XXXXmAh? More is not always better
Think of cars... an american car(ex Ford Mustang) has an 4000cm3 engine producing 200Hp . Subaru has an 2400cm3 engine producing 300hp
But i could be wrong
Cheers !
You can try wiping battery stats
How do I go about wiping the battery stats? I'm using the stock rom BTW
You need a custom recovery (root your phone first)
You can gohere if you are unfamiliar with these terms
You can do it without custom recovery if you are rooted. Use either Battery Calibration app or Root Toolbox app. Both available in the market.

ye market has a few tools to calibrate your battery for you
calibrated
So I've rooted and calibrated the battery... but it seems that it hasn't changed anything. It is weird that an extended battery twice the size of the original lasts exactly as long (or less) than the original battery
Charge your battery to full, 100%, then wipe battery stats, and allow your battery to DIE. Then your problem should be fixed. i went through the same problem, i bought a special battery with better battery life and my Optimus t, running at 806/480 on smartass governor can run for about 4 days without dying, and thats with constant use

mah DOES matter!
Battery life is dictated by the mah and how you use your phone. It sounds like the battery you received is defective which happens when you buy them from sites like ebay or amazon. Is there a return policy or warranty on the battery? You should definitely get more talk time and standby time with an extended battery.
It is a common misconception that you have to let the battery drain all the way. These are li-ion batteries which prefer a shallow discharge. Meaning, they prefer to be charged when they are at about 25% capacity.
Best of luck to you!

So true. The closer they remain to fully charged the longer they last.
So I have just flashed the CM7 ICS Themed BETA, wiping everything.
I then charged to 100 percent, and used Battery Calibration app.
I have just setup some apps, and I have lost 10% battery life in 40 minutes
Display is using 85% battery life apparently.
Please help?
It can take up to a week to fully calibrate the battery. Since the battery doesn't have memory the phone has to get a feel for how much juice it actually has. Try it for a few days running the battery down and then charging it to full without unplugging. If that doesn't work you might want to try charging all the way then reflashing and immediately do a calibration.

Yeah, I'd calibrate the battery - wouldn't hurt.
Ideally always flash on a 100 % full battery to avoid problems like yours..

Cheers guys I've taken this all on board.
I'm on 13hrs on battery, its showing 16pc. Battery calibration app shows 3609mv however. This doesn't seem right to me. Am I correct in assuming the phones battery power is the mv listed and no battery is more like 100mv??
Could anyone explain the 'mv' term to me?
Is 0mv when it powers down? Is this indicative of power?
Thanks.
Lithium ion batteries never fully discharge. If they did the battery would not recharge again.
Sent from my MB860 using xda premium
mv referers to mV, as in Milivolt. Most li-ion batteries are rated at 3.7V or 3700mV. A nominal full charge should be around 4.2V or 4200mV.

That's 35 minutes of active use. 10% isn't outside the realm of the possible.
I usually can go a full day on 60% battery, but this morning Facebook, the interwebs and text messaging put me from 100% to 77% in the course of 30 minutes. Draining 10% in 45 minutes does not seem out of the realm of possibility
I get mine to last around 20-26 hrs on a single charge, of course depending on use. but i hardly leave the house and dont use it a whole lot. One thing to make sure of is setting up profiles on SetCPU and/or undervolting. i just posted my setup on another thread. http://forum.xda-developers.com/showpost.php?p=20284361&postcount=28
so after you clicked the battery calibration button and it said calibration successful, you're wondering why the battery is dropping so fast under use right away?
Easy answer my friend, when you first use the battery calibration app, the first cycle (when phone is being used) will always drain a lot faster than the 2nd and 3rd time around.
The battery calibration app, wipes the battery stats, and makes a new one, however that does take at least 1 - 2 times of a full charge/discharge of the battery. There is a battery tread in the atrix general forum i believe for cailbration steps, etc to go about successfully doing a complete calibration when flashing from rom to rom.
Hope this helped
Hmm, maybe I am just upset that I have to charge every night.
Coming from a BlackBerry 9780 I could go 2 days with semi-heavy use.
I am now using the official Motorola cable, and only charging from very low to full.
Thank you for the advice.

Try getting one of these:
4800mah extended battery
1900mah extended battery
Problem Solved.
Bluetooth radio was killing my battery. WiFi is fine leaving it on as it disables in stand by, but bluetooth was absolutely draining everything.
thanks for the update
I agree, 10% loss in 40 minutes of active usage is not bad. If the OP had better battery life before he flashed to new ICS themed CM7 beta rom, maybe the new rom is to blame??? I'd OC/UV, possibly with the latest faux123 kernel.
