I have a battery widget that showing me very slow charging speeds and very high drainage under little use such as phone idle? any reason why?
What does spare parts battery info say? Is it just the widget or actually battery issue? Have u wiped your battery stats in recovery and done the battery cycle process?

Since battery widgets use battery I have been using a battery app that show the battery level only when i click on it.
Darchdroid has an option that puts thr battery percentage in the battery meter. Anyone know if this would use battery?

Huh?
I've been using BatteryLife's widget and it doesn't use (hardly) any battery... It never even shows up in my battery usage menus... Unless the programmer isn't any good at making the widget, I see no reason that a battery meter should use that much battery...
And as far as I know, putting the battery percentage in the status bar uses none... It just takes the value that makes the little icon change the image and displays it...
Hi guys,
I'd gladly post this on the CM7 RC's thread over at the dev forum but I have yet to accumulate 10 posts.
Lately I've been experiencing weird battery % issues in CM7RC2 and now CM7RC4, that the charging would be stuck at a certain percentage even if I charged it overnight. It never goes to full, until I pulled the battery and rebooted.
Is something wrong with my battery?
Thanks in advanced!
Are you using an official battery or a third-party battery?
I'm using the official one
I'd try charging the battery to full then wiping battery stats from within Clockwork Recovery.

I would definitely try this.. I had the same problem and it worked for me.. after you reset the stats, drain the battery again till the phone dies, fully charge again, and wipe again

First, doing the battery drain is effective in calibrating the battery meter but is still probably a bad idea because by doing it you are decreasing how much charge the battery can hold (i.e., a full charge will not last as long). It might not be super noticeable, and doing it once in a blue moon is likely not a big deal, but don't do it often or you'll just end up having to replace your battery. Deleting battery stats should be enough to correct the OP's problem, and allowing your phone to recalibrate under normal use is fine but takes longer.
That said, I do the battery drain anyway, but I would definitely suggest not doing it more than once every 6+ months. Wiping battery stats often is not necessary at all, unless of course you are actually having a problem like the OP is.
Second, you definitely should not clear battery stats AFTER performing a battery drain and recharge. The whole point of doing the battery drain is to let the phone gather new information about the battery since you just wiped the battery stats. If you wipe them again after doing that, the battery drain was useless.
hi can send me via pm callibrated batterystats.bin? big thanx
It makes no sense to use the battery stat of someone else.
The reason for a dynamic battery stat is, that every battery is a bit different. Also the different usage of phones leads to different battery stats.
You will probably not damage your battery, as it has its charge and empty limits independend from the battery stats.
So there is no difference from full charged to empty battery by changing the battery stats. The shown graph, how it drains is a bit different.
If you feel, that your battery drains too fast, check your configuration.
Cpu spy is a good indicator, how much the cpu drains.
Lower display brightness.
Use 3g instead of hsdpa.
Disable all background synchronizations.

Hello guys,
I have a problem with my battery this seems weird.
I don't have any battery drains but seems like the battery load when I'm not using it (screen off) like on the attached file. On the red bar I draw, you can notice it.
70-60% around and 40% around.
Anyone know why this happens?
Yes I've had that too after a reboot battery went from 70% to 75% not sure why, but is odd behaviour for li-ion batteries to do this. If it was a ni-cad or ni-mh I can understand this, its called recovery, after battery is unloaded it gains back voltage.

I have this problem too, can't do anything
Maybe its because intensive use then after the phone rest and gain back some %
So, I'm having a weird issue where my battery will lose 3-4% within a few minutes of unplugging from the charger after it's full. It will also stay at the same percentage for a long time, for example yesterday it was on 18% for nearly an hour. Pretty much what I'm saying is the battery life isn't bad at all but the percentage is way off. Is there any way to fix that or is it just that the battery may need replaced?
The battery needs calibration...that's all....use an app and follow instructions.....or just full charge then just drain the battery completely until the phone refuses to power on.....and then charge to 100% in power off mode....you will be good to go then
Justo use your phone normally
No need to calibrate nothing or do nothing it's a myth

Calibration is not a myth....calibration doesn't magically increase battery life....screen on time(SOT) Isn't affected by calibration........it just ensures that the battery percentage shown is equal to % charge left in battery......its just to know how much battery juice you are actually left with.
Battery percentage can't be calibrated, battery stats file is wiped on 100% charge, unless the file is somehow corrupted or read only or some crazy stuff wipe it might fix issues.
% depends on voltage, calculated drain and stuff
A bad battery can cause those drops when the phone reads the actual voltage left
