Guys pls help..I have this problem,that when I'm charging my trinity,it couldn't reach 100% of charging (full charge) instead was stuck to 70%.eventhough i charge it overnight.I'm thinking if it is a battery prob or the charger. i am using the originally supplied charger & battery.
Thanks in advance...
Have you tried powering the unit off, removing the battery for, say, 15 seconds, then refitting it and rebooting?... Check the battery level after reboot?... Then retry charging again?...
Maybe a full discharge might help "reset" the above problem too?...
I'm not sure, but I think the Trinity battery management is quite dependant on so called "coulomb counting" and I reckon sometimes it goes a bit wrong.

i tried all your suggestion bro,after rebooting,the battery meter increased 10%,tried to recharge,but still can't reach full.i tried to turn off my device then charge it,this time it goes upto 90%.it's a good sign but,charging while my phone is turned on is better right?i have no computer around,maybe i'll try to charge thru USB later..if it went ok,maybe i'll buy a new charger..thanx loopyloo for that sound advice..

Try battery callibration procedure!
The actual standalone charger (if that's what you're referring to) has no intelligence in it to speak of. Battery charge monitoring/status will be an integral function to the phone itself using dedicated h/w.
Something's not quite right with your kit somehow. Maybe the battery has gone a bit wrong (could be replaced - how much use has it had?)... Rather that than the phone itself, in which case it'll need repair.
You can try tnyynt's suggestion of Battery Calibration. Basically this requires you to totally discharge the battery (I suggest thru normal use of your phone!) then when it shuts down "cos battery is flat" reboot the phone into its bootloader screen (power down, then press and hold Power & Camera buttons until Tri-colour screen is displayed)... Then just leave the phone until it powers off of its own accord.
This may take a few hours (I did mine recently and it took @4hrs!) but the battery should be as discharged as its possible to get by that point...
And if you're lucky, it might just sort your problem out when you next recharge!
Good luck dude!!!

thanx again LoopyLoo,you made this procedure (battery callibration) clear to me,on how to do it.will try this procedure and will report asap the result.hope it works (fingers crossed),and hope it's not an internal phone prob.
Thanx Bro!!:>
Let me know how you get on.
I'm a little baffled as to why you have problems with your friends charge too but not USB???...
battery callibration not worked...
I'm sorry to report that after 3 times of trying the battery callibration method,my trinity still doesn't reach its 100% capacity of charging thru the standalone charger..but mysteriously charge a 100% with USB charging..I'm still not really sure why this happened..maybe will try to see a mobile technician for PPC..anyways,thanx for all your suggestion..will report ASAP after going to a service center..
Anyone know the best way to calibrate the battery on the DHD
Simple, just let the battery completely drain and charge it back to 100%.

This is a nice guide, but how do I go if I have a phone that is not rotated slightly off because it automatically goes into recovery?
It hibernates?

By that, do you mean the fast boot option for the DHD? You can turn it off by going to 'Settings' > 'Applications' > uncheck 'Fast Boot' option. That'll allow you to fully shut down the phone.
No, cwm boots up the phone when the power cord is connected, making it impossible to charge in "offmode".. It's a known bug in cwm, and theres no fix for it as far as I know.

if you want it to stay off, than flash a stock recovery
if you want to calibrate the battery, than don't worry, just do it. It still does what it has to do ; )
This way seems to have improved my battery life...
1) Clear battery stats in CWM Recovery
2) Turn your device ON and Charge the device for 8 hours or more
3) Unplug, power off, remove battery for a few seconds
4) Re insert battery, power on, wait until fully booted, charge until green LED
ok thanks to all
Hi Guys,
Since a few weeks I have a weird problem with my u8800. The first thing I noticed was that the phone didn't charge properly; after a night of charging it would still not be fully charged. I thought it would be the battery that died (tho that would be a bit quick after half a year) so I replaced it with a replacement battery. This battery showed the same behaviour within a few days. Then I replaced the charger for another one; this kept things working for some time but eventually the problem returned. I also tried Wipe Battery Stats to no avail.
What's wrong? I dont't get it. If the phone's on the charger now, the red light is blinking. It doesn't charge beyond 3% so I can never take it off the charger.
I have Aurora ICS since a few months, keeping in pace with updates.
Any help would be very welcome cause this thing makes it impossible to use the phone as a mobile phone..
Install the official android 2.2 and see if the problem persists
Wipe the battery stats (in recovery). Afterwards try to fully reload the battery (even if it keeps blinking red) and keep it on the charger for 1-2 more hours. Then disconnect the charger and do not reload the battery until the phone turns itself off. Charge it fully one more time.
After following this procedure your battery should be fine. If wiping the battery stats in recovery does not work, there should be a program on the market which does the same.
If the procedure does not resolve the problem please send the device in for repair. If the battery charge does not go up to 100% after following the procedure please do the same. This is a hardware error.

Hi,
I wiped battery stats but charging won't go beyond 5%. What is the name of the app you talk about?
FORGET wipe battery stats, everyone knows that is placebo!!

I would do that, but it seems risky on a battery with only 5% accu left. AFAIK you cant do these operations with the usb connection as power source right?

Plug your phone to the charger (not usb) and you shouldn't have problems...
But how do I flash 2.2 without usb connection?
Format sdcard and put update on it with some adapter or go CWM > mounts and storage > USB mount.

Put update file into the sdcard/internal card, plug the phone to the charger, and start the update by simply press Vol+, Vol- and Power.
Simple

Sorry for asking, but is there any clear reason why you guys expect flashing 2.2 might help? I ask because I expect this will cost me quite some time and I am trying to see what my succes chance is.
And, do you think I would be able to go back to Aurora ICS after flashing 2.2? I wouldn't want te be stuck on 2.2..
Thanks!

Because 2.2 is the most stable rom/kernel. This way you can see if the problem is with your actual Aurora, or it's an hardware problem.
And yes, if you flash 2.2 you can go again to 2.3 and then flash Aurora ICS.
And please, read/search a little bit on the forum before placing those questions. Those questions have been answered a million times!

Not everyone knows that, at least I did not. I thought that maybe the ROM just wasn't showing the information correctly and therefore suggested wiping the stats. But if it does not work, forget it.
In this case flashing a different ROM won't help. A battery that cannot be loaded is a hardware defect - there has not been a single report that switching to Android 3 or 4 leads to this problem. The charging of the battery is only hardware-related (if it was software-related you would not be able to charge your phone when it is turned off!) and therefore the only possibility is that the device is defect.

This is wrong as I just explained. The charging process does not depend on Android or any software the OP could modify/change.

As I said, it is one of two: it could be a problem with Aurora installation or an hardware problem.
Install 2.2. If it is a rom problem, it should work right with 2.2 (it could be some kind of problem during the installation that have corrupted some files.)
If it is an hardware problem, it'll continue to have the problem. Simple

Please read once more; I stated why the Aurora installation has nothing to do with this. I cannot explain this better than I already did, but I'll try again if there is something confusing.

I don't have this problem with X5, but I've tried to fix it on a friend's other android model.
The behaviour was similar, the battery never goes to 100 % and can show from 80% 1% after minutes, and phone deactivated.
First I thought that was rom' s problem(had a CM7 custom rom), so I made a full wipe.
Problem doesn' t solved. After I changed the rom with another one(Ligux), but problem still there. Then I tried to charge it with another cable and without to power on. No difference.
So, I've flash the official rom. After that I managed to charge it normally until 100%. And seems that working fine now. The official roms change more things on the device than any custom, and seems that this problem caused from another part of the software which doesn't belong to system or boot.img(these are the parts which custom roms usually replace).
If you read the official PDF file that comes with stock roms it actually specifies that you should REMOVE THE BATTERY and connect it directly via USB while flashing the ROM So 5% charge is not even needed, just remove the battery and flash a stock rom!
OK, somehow the problem spontaneously solved itself and my phone worked fine for some time. But now it's back unfortunately. This time however I saw how it started. I think this is what happens: the battery goes too empty. So the phone crashes because of that (no proper shutdown). Then when putting it on the charger it sees the battery that is too empty as a faulty battery (indicated by the red blinking led, no charging animation visible). The phone won't power on.
There's a trick to get it to turn on though: remove the battery, plug in the power cable and it turns on. As soon as the Huawei logo appears put the battery back in (or a boot loop will happen). Then, there's a chance it will start charging again (though sometimes that only happens after many attempts).
Now the question is, why does it go too empty and is it possible to prevent this?
II have rooted U8800 to Geno Cm7.2. As soon as it starts the battery status shows 0%. I have another U8800 with me. I changed battery and charger cable too. When I insert new battery into old mobile it shows 64 cent battery level but in new mobile after rooting it shows 9 %. what could be the issue. I am guessing Bootloader but please help me out. Thanks

Plug it via usb without the battery and turn it on. Then plug it in when it fully boots. It usually fixes it.

Hey guys,
I noticed this yesterday my Nexus 4 (running PA 3.6, franco milestone 1) shut down at 30% charge. I went home and charged it (it showed 0 when I started charging it) to 100% continuously.
Today too the phone shut down when it was around 32-31% and now charging has again started from 0%.
What could be the issue?
I have tried the battery calibration app even though I know it does nothing.
Any ideas?

I have been flashing nightlies merrily on the Nexus4, never had to recalibrate the battery, though it sounds like your does need that. (I had a Desire HD before this, and it was very sensitive to errors in battery calibration)
How about if you charge the phone fully then either reflash the ROM or flash a nandroid backup you've made? Either of those options will overwrite the battery stats file - if that's the problem.
It could be that the chip in the battery is malfunctioning, ie a new battery could be needed, but that sounds much less likely

Okay I'll try reflashing the ROM when I'm at a 100%, I know deleting the batterystats.bin file doesn't do anything but I did that anyways yesterday, but it seems it didn't fix the calibration issue.
Any other ideas I could try while I charge my phone to a 100%?

Hi, @paul c, I would like to inform you that my phone's discharging just fine (charged it to a 100% last night and it's currently at 48%, I didn't reflash my ROM but I did reboot it once. I also haven't charged it since then)
Could you tell me what's the minimum and maximum battery voltage? I am guessing that the max voltage is around 4200mV but what's the minimum? Also, can we calculate the REAL battery %age from the voltage that is displayed by apps like DashClock? If we can do that could you tell me how/what formula we use to do that?
I know I'm asking a lot of questions and I would really appreciate any help here !
Thanks!

Hi,
I was inspecting the battery's voltage/charge the entire day today and I realized that at around 36% the voltage went around 3000mV (3100mV, Nexus 4's battery is rated at 3800mV and it maxes at around 4200mV). After that when I plugged it back in and turned it on it started charging from 0%.
I think the battery is at fault.
Is there any fix for this which does not involve replacing the battery?
Thanks!

Unfortunately this didn't work for me. I tried charging through the night and then discharging it completely and charging it completely again. I also tried deleting the batterystats file (even though I know it doesn't do anything)
So what do you suggest I should do? Get the phone replaced or get the battery changed?
I live in India and the phone is from Canada, so replacing the phone will take some time but I can get the battery replaced for around $20
Also my nexus is also showing +ve mA values while it's not charging, and the values are absolutely crazy, +268, +168, +1171 (in batter monitor widget)
Please tell me what I should do.

Okay, I got my battery replaced, drained it to 0% (after a full charge) and going to charge it completely by the travel adapter that I purchased from the service center.
Attached are the pics of my old battery, I don't know if you can see it but it's swollen. If I recall I used a nexus s' charging cable to charge the phone from a computer and it was charging like AC (my kernel usb fast charge was OFF) and it also never detected my phone in the explorer (Windows)
My problem's solved now, it was a battery issue for me. I upgraded to PA 4.3 in the process by the way
So I guess I'll stick to my regular micro USB cable and charge via the travel adapter whenever possible, thank you everyone for your inputs!
