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.

It's a 3500mAh extended battery.
I put it on the charger and it doesn't charge, the charging light just flashes and battery monitor widget just shows it discharge until it hits zero and then it charges up to 100% really fast (but it doesn't get a good charge, since reading feeds for 30 min took it down to 60%)
Last time I fixed this by bump charging with the phone off and then it lasted for a week or so pretty good.
Well it did it again last night, so I tried bump charging and resetting battery stats. After reboot it fell to 85% pretty fast.
Another odd thing it's done is it will be at like 65% and then after a reboot it will sit at 1% for the rest of the day until the battery dies. Pulling the battery out and putting it back in fixes this.
Is this just a crappy battery or is something up with the phone's charging circuits?
What rom/kernel are you on?
I have the 3500 battery, too, and I'll go from 100% to 90% pretty quickly. Calibrated twice, too. I figure that's just an issue with the nonlinear (or at least different voltage curve trends from 100%-0%) voltage output of the extended battery.

ACS 1.1.0 don't know if that's related though.
What worries me more is the not charging issue.

Have you tried calibrating it and clearing your batt stats in CWM?
Do you BONSAI?
Tried clearing batt stats a couple times... Now when the phone restarts, it thinks that the % is really low even for the STOCK battery...
Been sitting at 16% for 3 hours with use. (was 55% before reboot)

What were the conditions when you cleared the stats? You need to either fully charge the battery on and external charger or when the phone is off. Then boot into CWM and clear the stats.

So after some time I've been battling with my battery life through the day. Few months back it was great, Id easily get a day no problem! Then I found I had a wakelock issue and had that fixed.
I now suddenly have almost multiple things going on at once but first a small back story.
Went to bed one night and had it plugged into the wall. Went to bed at 60% and woke up and my phone was down to 6%. I thought, well the usb port is bad or the cable. Took it into the sprint store, they of course say "it looks like its charging just fine, the light is coming on" (the light was on during the night too).
They checked the battery and they said it was bad. Im wanting to take it to another store and have them check, because either: they didnt want to replace me with a new phone or replace the usb port if thats bad.
1) Bad battery- in a matter of 30minutes (during my lunch break at work) my battery dropped from 63% to 14%- only used 3g for facebook and sent 2 text messages. And my phone is undervolted and underclocked
2) Possible bad usb port- I plug my phone in all day at work, and 90% of the time the screen is off. The % of the battery doesnt increase, but maybe decreases slightly (I have data and everything turned off while at work because I get no data signal).
3) wakelock- so suddenly I'm getting a huge percentage of system usage of 54% in my battery stats. A few months back it was maybe 1%? I flashed the .img that sets the wimax, PRI, NV, etc to what fixed the issue back then. Im just confused how this has come back now when I havent even updated anything related only my rom (MIUI 1.8.26).
So I've ordered 2 2000mah batteries off ebay- I wasnt going to pay $40 from a battery story across from the sprint store (as they didnt have any stock, only extended batteries).
If anyone has had a similar experience, or would know what is the culprit would love to get feedback. Hopefully I can get this fixed soon. Maybe just a trial and error.
Something really strange just happened. I checked my phone just now and the battery is at 98% and just maybe 30minutes earlier it shut off because of low battery
What I explained before about using my phone on my lunch break was only 2 hours ago and showed 16%.
I always wipe my battery states when I update my ROM or install a new kernal.

Don't wipe battery stats if you don't have a full battery, it'll keep your battery from charging fully.
It may be the battery, but since you're getting new batteries you'll know then. If you didn't get an external charger, I'd suggest doing so. That way you can guarantee that your extended batteries get a full charge, and you can switch out a dead battery with a fully charged one if you keep having problems. The usb port on the Evo is crappy anyway, but if the light comes on and stays on & you can transfer data through the usb port then I doubt that's the problem.
It could be hardware failure, but wait until you get a new battery and have properly calibrated to come to that conclusion.
In the meantime download Battery Monitor Widget, that should show you your true battery capacity even if the system will not. You don't have to use the widget, you can just open the app. Once you see that your battery is fully charged, calibrate your battery properly. Wipe battery stats at 100%, let it drain until it shuts off, charge to 100% without breaks, and you should be good to go.
Good luck!

Thanks for that!
I just bought a battery from BB to hold me over (50$ for a 1750mah battery?! )
when it charges to 100%, should I go into recovery, or use battery calibrator (app)?
Ill install that battery monitor too
BMW has the feature to wipe stats. I also recomend to look at the reports and judge when the battery is full by looking at mV. 4200mV is full charge. Then wipe stats FIRST, then unplug and run down completely, then recharge fully with out unplugging.

Ya just noticed BMW had that feature. Forgot I had a menu button. LOL!
This battery I got at BB is a "1750mah".
You know what I realized what might be the issue? Back a few weeks ago, I bought an extended battery to use to take videos at a concert. At that point I wiped the battery stats at 100% of the 2500mah or so battery..
Recently my battery went to crap on me and won't hold a charge for more than 8 minutes. It says 100% and when it hits 85% a few minutes later it shuts off. When I turn it back on it says 3% left. I've calibrated it about 20+ times, nothing works so I know it has to be the battery. Here's my question. When my new battery arrives (it's a larger one compared to stock), do I wipe the stats before putting it in? Or just take the stock battery out and put the new one in to charge? Thanks, anyone who reads!
If the battery ships fully charged, or you charge it externally before using it, then yes.
Otherwise, I'd put the battery in and charge it fully, then wipe battery stats & do a complete calibration.
Maybe someone with experience can help you out a little more. I have extra batteries but never wiped battery stats. But I charge them in an external charger so there's no need.

man i been having this strange problem too but i took my battery to sprint and they said its a good battery so im lost and this drop happens on any rom i flash or any kernal i have tried evrything from re-calibrate to htc fix where u let it charge then unplug and plug it back when u get your new battery let me know how it goes

That would be ideal if I could charge it before going in the phone. What if I just leave my phone shut off and put the battery in to just charge it?

Got you, bud. New batt comes in tomorrow, I'll see if it fixes the problem. I hope so, anyway.
I just put a new stock battery in and did the calibration as soon as it charged the first time.
Seems like it worked fine.
Okay for anyone that ever comes to this thread months down the road here is what happened in my case.
I went to Sprint, the gentleman asked what could he do for me and I asked him to test my battery. Before even taking it he said, "I'll test it but it's probably going to come up green." I asked why was what, and he replied, "Because unless something is really wrong with it, they all say green." So I asked him to try it out anyway. A couple seconds later he comes back and says, "Congratulations, you're the first person I've ever seen with a bad battery." I immediately did a, "YES!" Because if the battery wasn't the problem then I would have had to get a new phone.
So there you go, my battery was totally messed up, had to get a replacement.
My phone just started to do this about a week ago.
I tried reflashing, wiping cache/data, factory reset- nothing.
Whenever I charge, it will either charge significantly slow, or say charging but the percentage just goes down as if it wasn't even charging in the first place.
So I powered off for the entire night, (8-9 hours) and it will say fully charged. And I keep it connected to the charger but when I take a look at the phone again about 15 min later it reads 83% battery and charging.
I was really annoyed so I just left my phone on the charger again while I took a power nap (1-2 Hours) and after that I take a look and now it reads 68%.
The other day I saw it was fully charged so I took it off the charger and went on with my day. After, not even about 8 hours, it was already 10%.
It's like it only charges normally when the phone is shut off. Do I just need to replace the battery? Or is it something with the phone that drains the battery so quickly? I've already ordered a replacement extended battery off of Amazon just in case.
Most likely your battery. Go into battery stats and see whats apps are having high usage. Or download Gsam.

Im pretty sure its the battery now, the stats are normal and it doesn't seem like one process is hogging all the cpu. Can't wait for my extended battery next week, i cant last a week more with this annoying battery issue. Any suggestions for now?

Hey guys. So I was thinking my battery problem could just be a bad battery... Got some new ankers, charged them with the external battery charger. Battery lasted the time it used to: (4+ hrs screen on). I kept the battery in my phone, charged it via USB wall charger (stock) showed full battery, but died much faster. Any chance the original wall charger is being stopped before it's fully charged but sayin it is?
Btw tried battery stats wiper stuff didn't help

Battery stats wiping is not a thing. It's a myth. This happens every time you unplug the phone when its' above a 90% charge. Most battery stat wiping apps don't even do anything. They just say they did something. Even if you did wipe battery stats, it doesn't matter. It's not a thing.
The charger doesn't have voltage cutoff. So the charger isn't purposely stopping the charge. The phone itself does though. What ROM are you using? Have you tried with a different ROM?
Thanks yeah that's what I've been told but other people say to. I just wanted to say it so it wasn't advised I do a battery stats wipe ha. And yeah I've tried a few roms same situation I'll give it a few more runs through the batteries to see but it definitely burns through the battery in about half the time after full charge via USB rather than external charger
