Hello All,

First things first... Buy a battery charger. Next charging batteries at a fast rate is bad. Charge at a slow pace like these Battery Chargers do. Once you charge your batteries you'll see a great improvement on SOT and batter battery life over all

Battery Charger
How long does the charging last .. Its annoying .. If i reach 100% i get 20 percent drain while using it for 40 mins .. Then i have to remove the battery and plug ir in again to have an accurate reading ..

From 20% takes roughly 2HRs but depends on the mah you have on your battery

I've tested how long it takes on my 4500mah and about an 1hr 25m

Im using my fast charger .. 8 hours plugged in.. Is there a way im getting annoyed with this 9000mah battery .. I have to unplug it directly from the back and re insert it again to have an accurate reading .


Is there a way to recalibrate the batterystats.bin .. Tsk and btw im using MM

I'm sorry but the Mah is either Locked by the OS Kernel or theirs a Chip on the Motherboard telling the phone that cause no matter what battery i have other then the stock it doesn't say other than 3000mah. Look at my Thread as i have a Linked App to where you can edit the Mah in the App to whatever battery you have. It's the First Post

The app being battery monitor widget? I'm expecting my 9000mAh battery in the mail today, so just trying to get ahead of the game....

Well of course not. You need to be rooted to change the Mah if it's possible in the kernel or wherever the battery capacity is held at

I think its on the kernel side . tried everything but i think for whatever reason the mah rrading of the kernel still the same as 3000mah. When th battery resches 2% i just have to unplug the batgery and put it back in to get 60% juice from it ..

Did you check whether just a reboot is sufficient to "reset" it?

I have the same issue, and yes, a restart makes it read the extra juice.

Well ask around
That's his way of saying he doesn't know. Sadly it appears no one else does either. I asked about the reboot because it's alot easier to do that than pull the battery each time especially if it's in a case. Additionally if I have to pull the batterry after using 3000mah I might as well put in another 3000mah factory battery and charge the first one.

The question is this...when it reaches "0%" does the phone auto turn off or does it just KEEP showing 0%? I'm sure I could eventually come up with a tasker profile/task that would run on boot which could display the "real" remainder without a reboot if the phone will continue to run.
