Have similar issue with battery whilst on mobile data, drops 1% PM. Stopped using data and battery % stabilized. Checked again after 30 minutes and it had gone back up by 4% ???  

Have also noticed that after disconnecting USB cable the 'USB Connected' and 'USB debugging connected' icons remain in the status bar until the phone is rebooted. Does anyone else have this issue?

Neither of these issues really affect my usage though. Am staying with CM9 as this is by far the best rom i have used.

Did yall  calibrated your battery after flashing the rom??

Have flashed numerous times and have never had to calibrate. I agree with dazzo that this is going to be a calculation error hence not worried in the slightest about it.

[tcpaulh]

'calibrating' battery is literally pointless, always.

[Dazzozo]

This is a result of adding the battery statistics. We have not changed mobile data at all in R3. The statistics simply weight mobile data much higher in battery usage than it actually is. The stats are there, but they're not necessarily right.

Yes, calibrating the battery is pointless, it has been removed officially from CWM and the process happens every time you fully charge the device anyway. You are not calibrating anything, you are just wiping harmless statistics for that session.

To all those who have the battery drain, what happens if you boot into recovery, wipe cache, wipe dalvic cache and then fix permissions? That something I have had before on my old phone was needing to do the wipes and permissions fix which stopped the battery drain magically. May help, may not, you don't lose anything if you do it's worth a try.
My battery has been great on R3. 20% discharged and 5 hours usage, 3g always on and some phone calls and texts. Really happy with that.

Also might be worth letting the battery run right down at least once and then fully charging, .

Well they weren't very smart smartphones then.

Do you think it makes sense to stop charging something when it's full and then let it slowly discharge to a certain level brfore switching itself back on?

It is.

And that's why it does.

u didn't get me correctly... did i say i left my mobile plugged in even after its 1i00%...... i said, when i plugged out with 100% , in morning i see only 89% without any use as i was sleeping lol... now let me show the proof ... down...

I'm having the drain issue in 3G too, but in R2. O didn't tried R3 yet.

I think you should tweak it the other way Daz then everyone will believe that battery life is great. Problem solved!

[tcpaulh]

fbc, in order to avoid damage, most (all?) phones have battery charging logic. They charge then back off. Constantly keeping 100% while on charge would significantly hasten your battery's demise. It would kill it.

The conceit is that it still shows 100 even if charging logic has stopped before then in order to keep your battery healthy. Then, when you unplug it there is a discrepancy in the mAh and it adjusts to the real % charged over a short period.

If you want to force it to 100% you can try:

whats the fix permission for and is this perfomed after reboot?

[PaulMilbank]

I don't know, it may just be a superstitious voodoo thing like wiping battery stats. I think the idea is that an app or service is running incorrectly due to bad permissions and fixing them in CWM recovery stops that happening and resolves any potential issues. Wiping cache and dalvic cache is another common fixit for everything. It does not hurt to do it, you don't lose anything, just that first boot takes longer. Just reboot to recovery, do all three and then boot and run as normal.

just tried it,funny thing is it was on about 44% before now its on 31%

[Frankish]

Too many people worried about percentages and stats. Here's some facts for you.

I get through a work day (6 til 5) with about 70% battery left on this rom, on infusion, on stock+...

Just enjoy it don't worry

ye sbut have you tried it with 3g turned on,see how it goes down?

[Frankish]

I leave 3g on for the whole 11 hours I'm at work. Use some tapatalk, emails and eBay with a few texts.

[oldfella]

the battery consumption with 3G turned on depends on signal strength - in my area I have a very weak 3G signal and a very strong 2G signal.

so I keep 3G turned off.

Is there anyway to tweak camera parameters? Pictures come out really oversharpened and with very agressive noise reduction and contrast applied.

[Owl93]

Since I installed R3 i can't receive/send MMS is this normal? (and yes I've APNs configured)
