Flashed 9.0.0-HFS-1.4 with faux123-049 onto my G2X (P999), did a full wipe and wiped batter stats at 100% charge. I even unplugged and plugged in again several times with the phone off to make sure it was completely topped off.
I'm getting 999% battery and it will not change. Should I try it again? Run it through a few more charge/drain cycles?
Thanks.
Did you run a battery calibration app? Try battery calibrator, but make sure it can be used with ics.
It is very important! First zaradka battery should be about 12 hours. After complete relaxation, and so repeated several times. This at least ensures the correct operation of the battery.

For my HTC Hero, people on the boards recommended wiping battery stats and fully draining the battery for a couple of cycles.
Is it recommended for the Gtab as well? Are you able to wipe battery stats on this thing?

If you flash clockworkmod you can wipe battery stats.
What exactly does wiping battery stats do? My gtab never charges past 97%. Would this re-calibrate it so that full charge showed 100%?
It's not even a minor annoyance so I'm not intetrested in anything requiring me to drain completely but if this is a simple fix I would give it a go.
I have the same problem...battery won't charge past 96%. I've charged it overnight and wiped battery stats with no success. Any ideas how to fix this??

Same issue here, sadly. First time charging, it got up to 100%. After that now though, it stops charging at 98%. No amount of bump charging, battery stat wiping, draining battery, etc, has seemed to work.
It charges to 100% when using it while plugged in. I mean if it matters to you to see the big 100 once in a while ;-)
Not for me, lol. Meh, not a HUGE deal, but kind of a bummer.
Mine has the same issue. Charged overnight while powered on and while powered off and the highest the battery meter reads is 98%. I have attempted to wipe the battery stats, completely drain the battery, and wipe user data- all to no avail. While slightly irritating, it really seems as if the battery is functioning normally and the breakdown is simply the calibration of the software. I am easily getting 6-8 hours depending on usage.
Mine did that as well in the beginning, but after a bunch of good charge discharge cycles charges to 100%.
Last night I left the house with about 40% left on my battery. By the time I went home, my Sensation was completely drained. This was within 3 hours, which should not drain it to 0%, especially since it was asleep most of the time.
When I got home and I plugged it in, I booted it up and surprisingly, it booted up with 42%. Before plugging in it had no power left, and the phone wouldn't boot at all. I wiped my battery stats yesterday morning too, after charging it to 100% for a few hours.
Seems like my battery stats are VERY wrong right now, and I just wiped it again after charging it to 100% and leaving it there for a while. Does anyone else have this problem? I know some people are having random stats popping up here and there, but this still had 30% juice left before it just died out. Never happened before. I was able to nearly fully drain it just 3 days ago too (100-5%).
Charge to full, wipe again, and drain to about 5%. Charge full and repeat. It usually takes a few cycles to correct battery stats.

I'd also recommend this application from the market for battery calibration, although you need root.

Alright, thanks, I'll try that. Hopefully it gives me an accurate reading
Hi
I have tried to get the battery to calibrate to 100% using the Battery Calibration 1.3 Nexus app.
I have thalamus 2.6.35.14 r2 kernel installed on my phone which is a requirement of the Calibration app.
I have done tried it twice and successful got it to achieve learning mode but it did fully charge, but the battery age was only reading to 94% when I restarted it in the app. I wanted to try it once more and power off instead of restarting it, but Learning mode will not activate any more.
Learning mode gets activated when the battery drains to 3201mV, but mine won't activate, it goes to 3190mV and my phone shuts down. I have tried to reset the battery stats, wipe delvik cache. I did a have modded ver of the kernel 2.6.35.14, so I installed the above kernel but no joy.
Does any one have any ideas? I am quite frustrated... Tried it about 5 times tonight to activate learning mode, but no joy....
I doubt there is need for a "battery calibration app".
Just charge it full and delete /data/system/batterystats.bin
and on next restart it will relearn and calibrate on the battery.
I have done that before, and delete the battery stats, every time I install a new kernel. Phone shutdowns at 8%. I want the phone to shutdown at 0-1%
I read somewhere that the 95% full charge on the Samsung Nexus is intentional. Li-ion batteries don't like to be charged at 100% and drained near 1%. The battery is kept at its optimum charging capacity at 95%.
I don't use battery calibrators

You can't calibrate it perfectly.
No two batteries are the same.
If the voltage suddenly drops below a certain level the phone shuts done, even if it is only at 8%.
It is possible that with repeated use the display will get more accurate.
So, I wanted to calibrate my battery today, and so I charged it to 100%, turned it off and charged it to 100% again, then booted into cwr, wiped battery stats, restarted my phone. After a couple minutes I remembered to unplug my charger.
About an hour later off the charger, my phone went from about 70% battery to 0% and shut off automatically. I knew there was no way I actually ran it down all the way that fast, so I rebooted, and it showed it was at 4%. A couple minutes later it jumped up to 15%, and has been jumping back and forth for the past few hours.
I think I messed up the battery stats by keeping the phone on the charger after wiping the stats. How do I go about fixing it?
The only thing I can think of at the moment is running my phone until it actually dies, then charging to 100% while off, then wiping stats while actually unplugged. Will this work? Or, is there another solution?

Im just guessing but maybe wipe cache along with the battery stats and try to re calibrate from there. Did the battery get really hot, like over heat?
I would just cycle it complete and see what happens. I've had some screwy numbers show up during a calibration before. I wish I'd taken a screenshot of the time it dropped to 50%, fell instantly to 25%, then slowly rose to about 42% before it started falling again. It was freaky. Once the full cycle was done, it didn't do it again.
I don't know if it's the ROM itself, the battery or any other problem but every time my phone dies & I put it on the charge for a couple of minutes, I turn it back on & the battery level jumps up about 30%. What should I do about this?
i.e. I'm not running on the stock ROM.
It might have to do with the Sensation's issue with reporting battery levels accurately--sort of like how your phone stays at 100% for several hours before finally dropping down.
Is it a stock battery or large capicity version, if the larger version there is an issue with some roms or phones recognising the battery correctly
It's the stock battery that came with the phone...do I have to calibrate the battery?
One thing you could try is charging the battery to 100%, then booting into clockworkmod recovery, go to advanced, and click wipe battery stats. Then once the phone boots just unplug it and let it drain from normal use, and charge it to a hundred another 2-3 times and that should get the battery back on track. I did this after changing roms and it worked for me
may some of the wipe battery options can help you
