hey everyone! I bought an extended battery from sedio a few weeks ago and I noticed that the battery percentage doesn't display correctly. It shows normally from 100% to 0% but then it stays on 0% for at least 6 more hours before dying. I've tried different roms as well as clearing battery stats and nothing seems to work. does anyone else have an extended battery with this problem or a solution?

nobody has any advice?
There's a battery calibration app somewhere on here. That should do it.
there are a couple of guides you should try out as well on here that will help you out. basically with phone off charge it to 100% the while it is still pulgged in pull the battery and and put it back in leaveing it plugged into wall charger the whole time. it should show back up with a low percentage let it charge until it stops (takes a while) and then clear you bat stats and calibrate with battery calibrating app. that what i have done with my regular battery from time to time when i have batteyr issues and it always seem to work like a champ. do some searching on the forums though and you will find step by step on how to do it

Thanks I will try this soon!
I've tried the above steps after reflashing a new ROM to no avail. I'm starting to think the phone won't physically recognise the bigger battery size. Any other help?

I would try charging the battery to full, than while plugged in pull the battery. The phone will reboot and eventually show a battery symbol with a question mark. Charge the battery for 2-4 more hours, than boot into recovery (if you have) and clear the battery stats. If you do not have recovery than use one of the many battery calibration apps that are on the market. Hope that helps!
Again tried what you said and still no success...

Have you tried widgets/apps such as Circle Battery Widget or ChargeBar? They might be able to read the actual battery life as the default one will not be setup to know your extended battery.

Yes nothing will work i am having a similar issue with my phone OEM battery 1880mah and the phone is only recognizing it 500mah.you can also check that if you have a rooted phone by viewing charge-full-design in sys/class/power-supply/battery and it can only be changed with the correct mah of the battery if we can some how modify the kernel or battery driver.
This has been covered in the Mugen battery thread. Its nothing to do with calibration, it is a hardware limitation of the Atrix. The battery status indicator covers the first 2000mah of the battery, from 100% to 2%, all the further capacitance of the extended battery (1200mah for the Seidio and 2800mah for the Mugen) the phone usually shows 1% battery charge.
You can use Light Flow to turn off the annoying flashing red led.

I was wondering how i would set up my phone. Reset batt stats, longer charge times or something on how to get the best out of the extended 3500 battery. Also any hints or advice?
i have the same one and i just cleared the stats after charging the battery till full.
Sorry bad post delete please. This message just this one lol.
How do I know its full. ? Just over charge it with it on or off?. That's what u wanted to know. And does the percentage become accurate after doing this?. As I understand right now it should only register at 1500 right until the batvstats are chnage and then registers as 3500. And should display % based on that

i let mine charge until the green light was on, then unplugged and waited for the light to go out and re plugged did that a couple times until light is orange and charged till it was green again. havent had any problems.(knock on wood)
Do you know how long it took for that process? im getting it green now and will do the rest tonight with it being off. I am hoping that it registers the full battery capacity.
I've had very good luck with a $7 Chinese 3500mah from Amazon. I reset my stats through my battery widget but not until weeks after I had the battery. I don't think I was rooted when I first bought it.
The first day I got it I installed it and it showed 66%. I ran it down to 0% which took a pretty long time. Supposedly that's important, several cycles of complete discharge.
I have this docking station that is absolutely worthless as a docking station, but pretty awesome as an external battery charger. I use that to charge it, and sometimes charge it while its in the phone with the stock wall charger. The phone recognizes the %'s pretty close. At first it would drop to 80ish% pretty fast and then be really long between 50-80. Now it seems pretty steady all the way through.
Hmm I never thought to run down a Li-Ion battery due to it not actually having a memory.. Well i got it fully charged and I will see how long it takes to run down.
So I am waiting on how things will go for it lol. Thanks for the help guys. If anyone else has anything else feel free to chip in.
Get the battery monitor widget int he market, go into the settings and make sure you set it for the maH that your battery is, and then try the guide in my signature.
I have had my extended battery for some time now. I don't have BMW and have no history out my battery on my phone. All I did was put the extended battery in, played with the phone like crazy, killed the battery all the way, kept the phone off and charged it until 1 hour after the LED turned green. No issues.

I'm in the middle of a record setting run right now. This is very unusual. Usually I get 16-24 hours. My battery and EVO seem to have a mind of their own. But when it works it works good. I still struggle with intermittent 'android system' battery problems.
Lately my phone will go through a massive drain until it hits around 55% then it will drain normally. I have not changed anything since this started. Any suggestions? I'm thinking I may need to calibrate my battery.

That sounds like a good idea for your situation.

Thanks for your input. I want to wait a few days before I do it. So it will give it time to see if that really is the problem. This only happened yesterday and today so maybe tomorrow will be better. Besides the only time I really have to do it is later this week.

How does one calibrate a battery? Is this the same thing as "conditioning?"

You charge your battery to 100%, wipe batterystats.bin, then run the battery down to 0%, then charge uninterrupted back up to 100%
Battery Calibration does it help ?
I have a similar situation and i followed the battery re-calibration method too but still didnt help.
Situation - The battery would charge till 88% but will show its fully charged. Recently put Vivokat so now its even more prominent. Every reboot drops the battery by steps, like i would reboot and the battery would go from 80 to 65 just like that, no gradual decline or anything. And even after a full charge (the green light indicator is on) still the battery would continue charging.
Tried - I tried resetting the batterystats.bin file as suggested, fully charged till 100% then removed batterystats.bin file then allowed to discharge all the way then charged continuously till 100%. No outcome
Anything else that can be done ?
hi all! ive recently upgraded my battery to a 2300mah one, and the os recognizes it as 500mah (according to /sys/class/power_supply/battery/uevent). have tried calibration, battery stats wipe, and letting it fully discharge, and then charging fully while switched off. have read about a method: letting the phone fully charge, switch it off, disconnect charger, pull out battery, connect charger, put in battery, and let it charge again fully. this didnt work either. the real problem is that whenever i charge the phone, it drops to 1% in about 5 hours, than it gets stuck, and i can use the phone for 1 day after that (with wifi/3g/bluetooth/gps on). this means i get false battery percentage readings. has anybody any idea on how to solve this?
In CWM, there is a menu you can erase the battery history. Erase it when your battery is at below 10% and recharge it to 100% plus another 1 hour at full charged.
There is a selling of 1700mAh gold battery for Defy and this one is pretty good and almost rated working like the genuine OEM battery.

do you mean wiping battery stats in cwm advanced? already done that a thousand times in thousand ways, but that only deletes the batterystats.bin. thats just battery history. i have an upgraded battery, i wanna clear ALL info about the old one. wiping stats just wont do it. but thanks anyways
please help, 5 friends of mine have the same issue with the same battery, and we have no idea how to solve it (even reflashing the kernel didnt work). according to battery monitor widget, the battery dies when its around 3100mv, and does charge till 4200-4300mv. and afaik the percentage reading are calculated from the voltage. so is there a way to reset the default voltage/percentage values?

I bought a new battery today, a Chinese knock-off battery which claims to have a capacity over 2000. I live in Mongolia, so that's basically my only option if I want a replacement battery, since there's basically no postal system here.
When I first put in the battery, it showed a 59% charge. After a few minutes and maybe a reboot, it showed a 20% charge. It consistently drained down to zero, and I'm charging it now.
I've experienced really strange battery drain with the former battery (also a Chinese knock-off) where it loses maybe 10 percent an hour on idle, so I figured the battery needs to be replaced. Is there anything I can do to calibrate it? I have a feeling that the charge is actually more than is being shown, but no way to confirm my suspicions. Am I right just to try to charge it to 100% and discharge it to 0% until the battery life gets better, or is there something else to do? I should mention I've tried resetting the battery stats in CWM with no real effect.
Thanks from Mongolia.
Go into recovery when battery is at 100% and go to advanced then clear battery stats or download battery config for rooted devices and clear battery stats that way.

Clearing battery stats achieves nothing other than deleting the stats on the what has been using battery power. Battery calibration isn't required on our phones.

if you want to increase battery life for your new battery, charge it fully to 100% whenever you charge it will increase charge storing capacity of the battery

Never, ever I repeat never let your battery drop below around 5%, and always charge it before it reaches zero. I use the Guage Battery widget v3 pro as it is very accurate, but you can also get the free version. You can & should use the free battery calibration tool from the Google play store, simply install it & charge the battery to 100% then run the calibration App. simples

Hello,
for a past few weeks I have a battery problem At first my phone was shutting down at 30-35%, today at 50% :O :O
I know everything about battery calibration, I did it at changing the ROM and did it last week when my phone was fully charged, in recovery. Battery monitor widget says that capacity is 790mAh after two cycles of charging.
I also create new battery in Battery monitor widget and it says that capacity is 1480mAh :/
You can see that now my battery is at 14% with 4123mV, that is not normal
Can it be that my battery is dead?
Does somebody has other method how to calibrate my battery?
Thank you very much

I can see that you use Sense rom so jump at Droidzone site and download some of the kernels with full battery calibration (I think it's #22 and up), flash it and that would solve the problem.

Or flash an AOSP rom and go to the nexus one development thread to find the battery calibration thread and follow those instructions.
