I recently bought a chinese tablet (Sumvision Cyclone Voyager). I found that it wont charge past 92%. After much research i discovered that the problem can be fixed by one of the following:
-removing the battery
-wiping battery in CWM
-Full discharge until off, remove battery, hold power 30 seconds, replace battery charge to 100%
But most of these things require removing the battery or using CWM. What if the battery is non-removable? Or you cant get CWM for you model?
FIX for LiPo non removable (very simple)
I found the fix is:
1. Full discharge until it turns off
2. Full recharge while off until it stops charging ( will prob get stuck at the last bit (92% in my case but when off it dosnt give percentage just keeps showing animation for last 1/3 of battery to be charged)
3. Remove charger and power on the device. Use it until it drops below 80%
4. Recharge again while its on until it gets stuck at X% (92% in my case)
5. This is the important part: while its stuck charging remove the mains plug from the socket on the mains while leaving the connector plugged into the device (dont turn switch off at wall actually unplug the ac adaptor from the mains socket)
6. wait 30 seconds and plug it back in to the mains socket.
-Leave and see if it charges. It may not work the first time. For me it worked on the 3rd attempt.

I was wondering if this is normal for the Raphael (I have a fuze) to charge VERY slowly..ive always charged via usb and read somewhere that usb does a trickle charge (i never knew this) so i tried an ac charger and still same thing..my kaiser (tilt) charged full in a few hours..this thing charges maybe half way in 2 or 3 hours...any ideas?
I have had my device plugged in (i.e. not USB) for a couple of hours now. The charge has gone up from about 30% to 88% and seems to have stopped there.
Usb charging takes much longer than charging via AC. My phone will go empty -> full battery in maybe 4 hours on AC power, and will not fully charge in 6 hours using usb.
Also, I have a setting where the screen doesnt turn off for 30 minutes when plugged in, plus much brighter. If this is the case and I am playing with the phone plugged in it takes even longer still (i.e. when I am charging at work).
dg252: It is possible that your battery may be charged, but the battery indicator is stuck. Let it charge till the LED stops pulsing, then soft reset.
I've found that the provided charger work very quickly, however standard mini-usb chargers or usb leads will take forever to fuly charge, if they do ever reach a full charge. I think I read somewhere that the provided charger works at a slightly higher ampage.
I installed MoKee rom ( from this thread http://forum.xda-developers.com/showthread.php?t=2699446 ) and after a day of normal usage my phone discharged to the 0%.
Now I plugged it to the charger but won't turn on, only the green light turn on.
I removed the battery and reinstalled but the same.
I used different battery charger, but won't turn on..
What can I do?
All these charger have 5v output, 1.0A output.
I don't have original photon Q charger.
PS: battery is cold, seems that charger is not charging.. after some minute the green led turn off until I disconnect and reconnect the cable

You have 3 options to fix it
1. you must connect other battery must be 3,7v to your phone mb with some wieres and flash some other rom , if this no help flesh stock soft with RDS lite
2. maybe somebody have photon q in your area and he give you battery for 10 - 20 min or charge your battery in his phone
3. buy / make motorola usb service/factory cable ( when you connect your phone with this cable you will be able to flash stock software even if you have dead battery )
a) make your own - http://forum.xda-developers.com/showthread.php?t=1077414

Hello!
I used a car charger for Lenovo A806, which seemed not to work, as battery drained and at last reached 0% and the phone turned off.
Now (the same day), even by using the plug charger (which worked perfectly the previous days), the phone will not turn on.
The normal battery voltage is 3,8 volts and normal charge voltage is 4,35 volts. However, a voltmeter shows the battery having almost 2,9 volts (as it is 0%).
I removed the battery and connected the phone to the charger. I measured the voltage at the battery pins in the phone and it shows under 3 volts, when it should be 4,35 volts, according to the phone specifications.
I cannot check the battery on another phone because it has different size.
Can there be a solution to this problem? Any answer welcome.
Thank you

I have read that wiping cache partition sometimes can solve problems like this.
But the recovery mode (Vol Up + Power) is in Chinese.
Which is the option for wiping cache partition?

The phone finally turns on and loads normally with full battery. But it cannot charge it. For example, when it is plugged in, the message on the screen is:
...
...
Charging 80%
Charging 79%
Charging 78%
...
...
And finally it turns off...
So from the beginning of story, my wife discharge phone to 0% and it turned off, after it turned off it wont charge any more, so i think she killed the battery. Bought new battery, replace and it's ALIVE, but when i connect fast charger xperia turning off ( puff black screen, on normal charger is showing it's charging and after 10 seconds puff same result ) and red light is on at the top ( new battery is 50% charged ).
So i connect old battery to Xperia Z1 and charge, old battery is working, connect to Z3 and it working without charger connect, when i connect charger phone turning off, and place where is connected battery to phone board getting really HOT when charger is connected.
I don't see any water on phone-board, and white marks near the place of connection with battery.
Have someone same problem, and have a solution?

Your charging module might be damaged. Try charging using the magnetic charger, it should work.
I have the exact same problem in my Xperia Z3 D 6633 . this is how the problem started. original battery started swelling but charging while it was alright and had charged but I saw the risk in keeping a battery that is swelling all the time so got a new battery and that second battery lasted for about 2 months after which one fine day it used to discharge in just under 20 seconds from hundred percent 20 and after that gradually it will not take any charge but at least I could make it pretend charging when I connected to AC and the phone was on as long as there was external power either from the AC or Power Bank. next this second battery was changed to a third battery . with the third battery in place all I could he is a red light there is no charging at all and no charging icon and phone is totally dead with a red light.
some other place I read that there should be a voltage difference of at least 4.2 v for a battery to work in that phone and III battery initially did work but when it was discharged it will simply not charge again.
when you say the charging module is not working what exactly does it look like and can it be changed easily please help me out thank you
Hi everybody,
it's a few days I have weird problem with SuperCharge.
I apologize for the lenght of this post, but I don't want to miss any detail that could help in solving my problem.
I recently replaced the battery with a new original one (I hope) bought from an eBay seller.
When I switched-on the smartphone, battery level was 58%. So, I used it normally and, when battery level lowered at 30%, I plugged-in the charger.
Completed the recharge, I used the phone as always.
At night, with 30% of battery level, I plugged-in the charger and I went to sleep.
The next day, in the morning, I turned on the screen and the battery level was 32%. I was confused... So, I un-plugged the charger, plugged it in again and the phone needed just few minutes to fully charge at 100% (very weird).
Then I normally used the phone for the entire day.
At night, with 30% of battery level, I plugged-in the charger and I went to sleep.
The day after in the morning I turned on the screen and again the battery wasn't fully charged. It was only 34%.
This time I unplugged the charger and I restarted the phone. After that, it showed 100%. So, in reality, the battery was fully charged!
This made me think it could have been a software related problem: so, I performed a Wipe-Cache-Partition and a battery re-calibration process.
After that, I noticed the charging process was slower, although the phone shows "Super-Charge" in the lock-screen.
So, I wanted to monitor the charging process with Ampere and this is what happens:
- as soon as I connect the charger, for the first few seconds the charging rises to about 4000mA (as it should);
- suddenly the charging stops, as if I disconnected the charger. At the same time, the battery temperature rises for one second to 44/45 ° C and then quickly returns to 32/34 ° C.
- after a few seconds, the phone starts charging again, but at 1600/1700mA.
- cyclically, therefore, the phone tries again to increase the charging to 4000mA, but, as soon as it reaches the peak, the same phenomenon described above is repeated.
I noticed that the charger overheats while charging.
I replaced the USB-C 5A cable, but the problem persists, so it's not cable related.
If, on the other hand, I use a non-5A USB-C cable, the phone recharges in FastCharge mode (2A) without interruptions and the charger does not heat up.
So, the problem exists only with SuperCharge.
Do you think the charger is defective?
Or is the new battery defective?
I thank in advance anyone who will help me. :fingers-crossed:
I noticed a similar problem with super charge.. When plugged in for charging, super charge doesnt show.. It takes super long to charge to even 50%.. So i tried other cables as well and same issue.. I restarted the phone a few times and then switched it off.. Plugged charger in and left it over night. I noticed the next day super charge was functioning correctly
