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.

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...
Hi,
The past few days my X10 is not charging very well.. It turns to 100% and if I look to it the next morning it is about 15%. And now it doesn't charge to 100%. It's very annoying now.
What can I do?
Bro! i think its a battery problem - if your battery level is let say 15% (or in status red) try this, take out the battery plug your x10 to the charger (while battery is taken out) and then while you have your x10 plugged in to the charger press and hold the power/sleep button youll feel it vibrate after the vibration put the battery back in, then your phone will boot up (if it did not boot up just turn it on your self) if your battery is faulty you should see the battery in 75-90% if this is the case you need to replace your battery it happend to me 2 weeks ago im experiencing reboots while using the phone with charger but then i noticed the battery life is so short like literaly if im at 100 then after playing 1 single game (angrybirds) for10mins on it it'll drop immediately to 50.
hi guys! i'm running cm7.2 on my su660 (it's a kang build which is ported from p990 official CM build). and i have a problem on charging the phone. when the phone have 10% of battery left, i plug in the charger, the phone show the charging symbol . but when i leave it sleep and come back after 'bout 3 hours, it still show 10%. but the voltage in sparepart is aproximate 4200 mV. so the battery is fully charged but the rom didn't regconize it. but then after some minutes turning the screen on, the rom show that phone is fully charged. so i guess that the battery percentage counter doesn't work why the phone is pluged in and sleep. so this is a rom issue? can i fix it myself?
PS: sorry for my poor English because i'm not a native English speaker. i'm from VietNam. i tried my best to explane my case. hope u can understand me!
If, after rooting or more likely that case after flashing a new rom, you often have battery reporting errors, and re-calibrating the battery along with some steps I will outline for you below will ensure that your battery is getting a full charge, and the battery reporting accuracy is right on. As far as power cycling, I don't know that it does much good. I run my device in performance mode all the time, and with a CPU overclock of 1.25GHz and various tweaks, I have about a day an a half to a day and a quarter of full runtime from my battery. This is with moderate to heavy usage (calls, emailing, text, gaming, web browsing, etc.) so you should have no problems getting acceptable battery performance after following these steps:
1. Take the case off your device (one of the latter steps involves taking the battery out from the phone while it's plugged in. Make sure your case won't stand in the way.)
2. Install Battery Calibration app from the market
3. Plug in your device to charge while it's on, wait till it gets to a 100%
4. When the charge is 100%, open the BatteryCalibration app and lookup what the charge is in MV while at 100%. Write it down.
My Atrix 2 was showing ~3400MV while at 100%, which is definitely not the maximum capacity.
5. Discharge your device completely until it shuts off.
A good way of doing this quickly is by turning on wifi, and a video player.
6. Without turning on the phone plug it into a wall charger and let it get to 100%
7. When it's at 100%, without unplugging it from the wall charger, take off the battery cover, and take the battery out.
Your phone will "reboot" and show a Missing Battery icon.
8. Without unplugging the phone from the wall charger or turning it on, put the battery back in and wait until the phone recognizes the battery.
9. Your battery should now be recognized by the phone, and showing a charge % significantly lower than 100%.
Mine showed only 5%.
10. Let it sit there charging for 2-3 hours (or more).
My phone wouldn't charge past 10%, but yours might. The numbers don't matter much as the phone is definitely getting additional charge that could have been lost while flashing ROMs, etc.
11. After 2-3 hours (or more), turn the phone on while holding the volume down button and get into CWM (if installed) or use Rom Manager (is device is supported).
Do not disconnect it from the charger still!
12. Wipe battery stats in CWM, reboot.
Do not disconnect it from the charger still!
13. When the phone turns on, go into Battery Calibration app again and look up your MV numbers -if you were like me, they should be significantly higher than before. After this whole process I had 4351MV at 100%, comparing to 3400MV before calibration.
Do not disconnect it from the charger still!
14. Before going to sleep - Install Watchdog Task Manager Lite from the market. Go into it's preferences, set CPU threshhold to 20%, check "Include phone processes", check "Monitor phone processes", check "Display all phone processes", set system CPU threshhold to 20% as well.
Do not disconnect it from the charger still!
15. Make sure your wifi and data connections are off. Now finally unplug the phone from the charger.
Go to bed, let your phone sleep too.
16. Success! Next morning check where your battery % is at and if you followed the instructions correctly / got lucky like me, your battery life should be 90% or more.
I went to bed with 98% and woke up to 94%. So, I consider this mission a success.

Hi
I would like to reset the battery stats on my S9+ because I have seen it live drop istantly from 14% to 4% , I'm not rooted but I have seen this procedure here:
Method 1
Discharge your phone fully until it turns itself off.
Turn it on again and let it turn itself off.
Plug your phone into a charger and, without turning it on, let it charge until the on-screen or LED indicator says 100 percent.
Unplug your charger.
Turn your phone on. It's likely that the battery indicator won't say 100 percent, so plug the charger back in (leave your phone on) and continue charging until it says 100 percent on-screen as well.
Unplug your phone and restart it. If it doesn't say 100 percent, plug the charger back in until it says 100 percent on screen.
Repeat this cycle until it says 100 percent (or as close as you think it's going to get) when you start it up without it being plugged in.
Now, let your battery discharge all the way down to 0 percent and let your phone turn off again.
Fully charge the battery one more time without interruption and you should have reset the Android system's battery percentage.
I have found this procedure here: https://www.androidpit.com/how-to-calibrate-the-battery-on-your-android-device
Is there anyone who can tell me if this is any good?
Thanks.
no, change the battery.
When it turns off at x%, open twrp, set timeout to maximum and brightness to maximum and let it consume the battery until it shutdown, doesnt matter if it says 50% or 0% on twrp and you saw your phone turn off at 3%, let it discharge on twrp until it shutdown. At that point your phone is completly discharged, if you turn it on you will see the led on the left corner blinking red. Charge the phone until 100%, unplug it a scroll the app drawer a little bit for a few seconds up to one minute, if it goes down to 99% or less, plug it in again and let it charge to 100%. Unplug it and use it. That process will recalibrate your battery.
Ended up with new battery repolaced myself today But ill give it a tray next time.
