Hiya
So I've got my new battery for the phone today, says it's 1600mAh even tho I doubt it, but as the stock is 1230mAh should I wipe battery stats when I've charged the 1600mAh battery to max or will there be no real difference?
Also, is there an app to see how much mA your battery packages atm, to see how much it is when it's fully charged for instance?

I just got my new 2150 mAh battery in today. Phone is off right now, with the new battery in it charging. Now I wiped the battery stats before I threw the new battery in, but should I do it again after the new battery has a full charge and I turn it on for the first time???
There has been a lot of vapor regarding battery stats. I have seen it claimed that stats (which to my mind only report things that have happened) can influence future battery performance.
That makes no sense to me whatsoever.
I do it with every install, just to do it, dont know what effect it has, but i never have issues with roms or kernels. Just my $.02.

The most widespread theory is you should first charge it all the way up, bump charge it once more, then clear the battery stats. You should then proceed to let the battery drain all the way down to 0, and when you recharge the software should charge the battery to a fuller amount.
Of course I don't know how much truth that actually has. I know when I did that, the next day wasn't great, but everyday after that for the next few days got marginally better (less of a drop in the morning).
As far as i understand it (i'm not an expert, just read a LOT of threads) wiping the battery stats won't have any effect on how well the battery charges - it just helps the phone report an accurate percentage as the battery discharges
welcome all who see this. alright, my phone is rooted, and i went to upgrade to gingerbread and i used the mikg rom 2.5:1-2. unfortunately i erased the battery stats not paying attention and talking. from then....the phone battery never charges.....even when plugged in it constantly sinks to nothing. even when i charged it turned off for 6 hours, it never gets past 15% HELP! i have tried to rewipe the battery stats, but i only get past draining the battery, because now it wont fully charge. i even bought an extended battery which also drains, but never charges! i am not sure what to do to get battery stats up to par, or to cause this phone to charge any battery! CAN SOMEONE PLEASE HELP! (much appreciated)
im a noob here so i really dont know what im talking about but i had almost the same problem when i bought my extended battery from sprint. first day of use was really good and when i went to charge the next time as soon as i unplugged the charger after a full charge the % would drop soo much...i was getting like 10 hrs which isnt much with an extended battery. i updated to mikg 2.53 and wiped the cache and all the usual and the battery stats and its seem to workin now 1d 4h 54m on battery....hopefully this helps
Use an external wall charger or a different phone to fully charge the battery. Then insert the battery and immediately wipe battery stats.
Should fix the problem.
Using an sbc kernel will allow you to fully charge the battery as well. Use something like Battery Monitor Widget to keep an eye on your charge - 4200mv is fully charged.

It almost sounds like a problem with the phone. I wipe battery stats everytime I flash a new Rom and I've never had problems. You might want to see if the battery will charge on someone else's phone first.

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

Over the course of months of flashing, I have noticed that my battery life drains really fast. I'm currently running AOKP. I think I calibrated the battery correctly yet I still have terrible battery life. I charged it to 100%, used an app, Battery Calibration, to reset the battery stats, let it drain to 0%, the plugged it back in. The battery said 57% so I charged it back to 100% yet the battery life is still awful. My brightness is at the lowest setting, my WiFi is off, and I am using Greenify to hibernate applications. I've attached pictures of my battery life (from GSam) and pictures of what my software looks like. What is causing the drain? How can I fix it? If anybody can help, I'd be very thankful.
Edit: I have a Hyperion 4200 mAh battery. I replaced the stock battery but it didn't seem to make a difference. The voltage reads at about ~4200 mAh when at 98%.
Edit 2: My battery was at ~60% then I shut it off and plugged it in. It is now at 2%... Should I charge to 100% then reset battery stats?
