This is my first post, hope you can understand what happens to my phone (SE X10 mini pro - U20i).
When I connect it to my wall charger, it starts charging normally, no problem. If I charge it overnight, what it is supposed to happen is that it charges to 100%, then it stops automatically the charging process, "waits" untill the battery drops a given percentage, not sure how much, and then charges again, and repeats this process until I disconect the phone. This is the normal process, and usually does this.
But some times, what it does is charging to 100%, stops charging and it remains in the 100%!!! Never drops, and it discharges the battery much more rapidly!! I have System Pannel, and when this happens I see that the processor is allways in the 10%, which is not usual in standby... and as the battery is discharging, the % doenst change, still shows 100%, when it is maybe in the 3800 mV. When I disconnect my phone, the % starts decreasing rapidly, as if it was trying to "compensate", ah in maybe 30/60 minutes reaches 50%... This is not normal, and I think it is some process that stops associating the % of the battery with the voltage.
Ever heard of something like this...? My phone is temporarily rooted with Z4mod, with stock firmware. 2.1
try this:
install xrecovery
make sure your battery is at 100% (let it charge over night)
go into xrecovery (press back while the SE logo appears while booting)
go to "advanced options"
delete battery stats
and drain your battery till your device turns off, doesnt matter how
No go. Doesn't solve it... Going to try to charge it tonight with the background data option turned on. Have it turned off to save battery. Probably won't solve it, but it doesn't hurt to try.
This weekend I've charged it WHILE turned off, during the night. Got it off the charger, symbol in screen appeared with full charge, turned it on, it immediatly shown 18% battery left... This is really weird. Can it have anything to do with not using the original charger? I'm using the original as a travel charger, in my bag, in case I need it at work, and at home I use a Nokia charger, with an output of 890 mA, and with the adapter to microUSB (which actually gets very hot). Do you think it can have anything to do with this issue?
Turn off data traffic and "sync now", you will save battery.
With data traffic and sync on, my phone last just one day ( about 24h ).
With it off, It last about 2 ~ 3 days.
Result: I just turn it on, when is needed.
try turning off data traffic and as ur phone is rooted use SetCpu and auto killer memory optimiser....nd never over charge ur phone....charge it only when the battery is <10% and charge it until it gets completely charged....nd as soon it gets charged disconnect it.....nd set the SetCpu to ondemand and auto killer to optimum...see if that works for u..
lso get ur battery checkd if thats ok...
Lately my phone has only been charging to 95%. At 95% it will say the battery is fully charged. I tried to wipe the battery stats but i am still not able to get it to go over 95. Has anyone had this problem, or can anyone give me advice on how to fix it?
If the voltage reads 4.2v, wipe the battery stats and restart the phone. It should read 100% after it boots up.
Make sure you have a backup phone for your SIM, or a phone you can forward your line to for the duration of steps below as it will involve your atrix tethered to power for the better part of the day (I did it during the day at work)
--------------------
Drain your device's battery dry (turn off all power saving and run everything you possibly can etc) To the point where it finally shuts itself off - Do not turn it back on.
Plug it into a wall charger and charge it up from 0 to %100. Just tap the power button every so often to check charge progress. Do not turn your device on. Anything more than a tap on that power button and you will turn your device on. If you turn your device on, the chair you are sitting in will swallow you whole. (Actually it will just hinder this process. If you ABSOLUTELY need to I'm sure it will be fine) Your notification light will also give you an idea of where things are at (red for low, amber for getting there, and green for almost done)
When your device reads %100, turn it on, all the while plugged in. If it still reads anything less than %100, download and install "battery calibration" from the market:
https://market.android.com/details?id=com.nema.batterycalibration&feature=search_result
Keep your device plugged in. Run the app - it will instruct you on what to do. It's very straightforward. Keep your device plugged in until fully charged to %100. It will take a dogs age for the stretch between %95 (or whatever) to %100, but it will eventually get there. Ignore "battery charged" notices, or anything else that contradicts what the app says the actual charge currently is.
When you finally hit %100 charge, and you should, wait another 15 minutes or so.
15 minutes after %100, press the big button on the app that says "calibrate". If you're as lucky as I, you will soon be enjoying approx. 1 day 13 hours run time (moderate use) with your device.

any one know what effect does soft rebooting has on battery stat file?
And how about factory resetting (from the privacy settings) effect on battery stat?

None. Because its not stored somewhere that that process erases it.

For some odd reason my phone won't charge past 98%?
I've tried clearing the battery stats but no change.
Any recommendations? I know its only 2% so its not much of a big deal.
Download Battery Calibration from the market and see what it says that your mv level is. it should be at or very close to 4200mv. Charge it over night and when you wake up check it to see what the max is...then hit Battery Calibration and don't charge it till it dies. My suggestion is to use it normally for the day and then play games or watch videos when you are ready to kill it. once you kill it let it charge all the way up again, then see what it charges to.
I'll let you know how it works out in a day or so.

This helped me with that issue
Funny trick. When it. Hits 98% connect it to your computer, mount it as none. And let it get to 100%. Then let it stay in the charger for 5 minutes after

Even when it says 100% it may not be charged all the way. Better to go by mV, 4200mV being full charge.
u don't have to download anything. just go into dialer and type in *#*#4636#*#* and open battery info. if u fully charged your phone, it should be at 4200mV. leave it plugged into the ac charger and remove the battery. hold in the volume down button and enter android recovery. erase battery stats then insert battery and reboot. should be fixed.
I found my Atrix totally discharged this morning, you know this situation, it does not start even plugged to AC charger. I switched my sim card into my spare phone. after ~15 min of waiting my Atrix did start and battery stat. showed 0%. at 12% (ater ~30 min) I shut down the phone via menu (long press power button -> shut down) and when big charging battery picture appears on the screen charging status was 60% ! same 60% I found when I boot the phone into OS (CM7). so I'm curious what caused that 50% jump in charging status and I'm not sure now when I'm at 100% is it 100% or just 50% ????????
Flash juggernaut's battery fix and then calibrate the battery to take care of that.

If I keep my phone on charging even after its on 100%, it starts rolling back. As in from 100 to 99 then 98, even if its pluggen in.
Don't know what kind of a problem this is, hardware or software.
Or there's some issue with the battery.
Please help.

Sometimes I have the same problem. I dont know if it is caused of a program running in a background or what, but reboot helps

I know the reboot helps.
But usually I put it on charging at night before sleeping.
And when I wake up in the morning, the battery % becomes even less than what it was when i plugged it in.
I'm usually in a hurry then to leave for college in the morning . Can't go to college with battery % less than even 10
Thanks for the reply anyway !

Maybe You have some program that syncs something all the time. Did You try to turn off data and wifi. You can always check it if the reason is the hardware or Software. Just make a backup of Your whole ROM, delete the data and leave the phone over night. I hope it is only software problem.
EDIT: Does Your battery go hot while charging? Oh, and try to wipe battery stats

Yes, my battery does get hot while charging.
And I did wipe the battery stats but its of no use.

Maybe there is really some program that is causing that. I had this problem rarely so I never cared. I had one program called Batterymonitor or sth. like that and it was the reason. Do You have such a program, that shows Your battery level or temperature?

Yes, I have setcpu and rom toolbox.
But would these applications really cause this problem?

The x10 charges the battery to full then if still plugged in it will stop charging until batt drains to set level ,then will charge to full again and over and over all night. X10 wont over charge batt when left plugged in. Kernel/bootloader handle this. There is an app current widget that can log charge levels.
EDIT: I had a tip on charging here but removed it after further research read more about batt here..

EDIT: the best tip I usr for battery life is, let batt runout until phone shuts off, then pull batt, then plug in charger, then replace batt into phone, then phone will boot, enter xrecovery on first boot and wipe batt stats. After wipe while still in xrec pull batt then unplug. Now plug in phone then insert batt. Phone should boot in charge mode( big batt icon only on screen) dont start phone untill light green for 1-2 hours to get full charge . I do this about once a month, when phone starts to shut off around 15%

As mentioned above as well, this is normal. After charging to 100%, the phone stops battery charging, and will activate charging again only when battery falls a bit (say 97%). Also, battery heating while on charging (and also when using the phone continuously while playing a game) is normal. Relax.. your phone is fine
@ToledoJab
I am having the same issue with battery... phone switching off at 15%, even at 22-23%, when playing a game or something. But switching it back on, and leaving it idle, phone might run for another 2 hours. So it is the extra load while running a game that the phone cant take any longer (i remember getting the 15%,10% and 5% reminders earlier while playing games)...? Does the battery calibrate method actually help in your case? does it go all the way down to 0% or 1% before shutting down.. ?
I just did this after posting that. And yes my phone reported warnings @ 25% 15 10 5 and then shutdown @ 1%.
This way is like reconditioning an old rechargeable ni-cad batt.
All this does is completey drain batt then, with least amount of drainage (phone on, apps& radios running) allows battery to full charge.
There is also a way called recalibrate battery. But this way over charges the batt.
EDIT: I think the phone load will effect reported batt left. I think batt gage use average loads to estimate remaining power. Meaning games, full brightness of LCD, radios -3g -GPS -WiFi -Bluetooth will use more than avg power
edit 2: I found this thread also has some very good points and links. after reading this i will not intentionally take my batt to 0%. I hit 0% about 1-2 times a month on accident as it is. i will just make sure when i do go 0% to wipe stats (dont know if it helps or not) then preform a long (overnight) full charge with phone off.
