After I done update to the 7 android my tablet won't fast charge anymore and it was doing the fast charge before the update can anyone help me
I have noticed same thing after updating to Android 7.0. I'm guessing that tablet does in fact fast change even though it is not showing "fast charging" text on the lock screen.
Yes, I confirmed it with a USB charger doctor, the tablet enters QC 3.0 mode (charge voltage at 9V), it just doesn't tell in lock screen.
Reset all setings,go to factory reset function.

Hello all.
I was wondering if there is a way of manually allowing this or not.
I was on a older version of the Crombi rom which seemed to allow this to work.
I have since updated to the latest and tried a few other different roms and it will only seem to charge out now it the tablet/dock is open and screen is on.
I would be fine if it would charge even if the tablet is open but screen off.
There are times where I only have the charger for the tablet and can borrow a usb cable and I became accustom to charging my phone that way.
Any ideas would be greatly appreciated.
Thank you
thats a bit strange, as I can charge both the tablet and dock together with it shut on mine..
does the dock charge by itself?
does the tablet charge by itself?
does the tablet accept charge from dock when Tablet is plugged into dock and shut?
(easy to test this one.. check % before and after on both and compare... say after 1/2 hour and see if there is a difference...as Dock should discharge in to Tablet, then stop once tablet is full and then you should only get deep sleep lossage....)
Yeah the tablet and the dock all charge okay.
I was trying to use the usb from the dock to charge my phone while it's closed.
When I'm out I watch stuff on the tablet and charge it and go to sleep and close the tablet and dock. But when I do that, it stops charging the phone I have plugged into that usb connection on the dock.
Right..understand..
The dock is going into full shut down/tablet is going into full shut down
..which most of us want.. This will be kernel based..
As while it would be good say on a long trip to be able to use the dock as an external battery top up device for phones..I don't think the Asus docks have ever been that smart..
Only thing I can think off is that you set WiFi to always on..thus the tablet is not going to go into the deep mode for some time after shut down..
You could ask in the grimlock kernel thread on the setting in the kernel on the expected time that it is set...
Okay I'll give that a shot.
I am already using grim lock anyway
so am currently running lollipop 5.0.2 on my Sony z2 when i plug in the charger it charges fine until it reach 89% then the screen start flashing(on/off) and the phone wont charge no more,should i reset my device or this is a hardware problem
There is no way to know until you reset the device. Also, do not forget that you can try to repair with Pc Companipon and to see whether there will be a result.
Share then if there is an effect.
Hi guys, first post , really nice site, need help.
My LG G5 (H850) is not rooted. It has recently been chewing through the battery quite fast so I decided to back it up and do a factory reset. Everything went fine for the backup and reset and restore but since I've done it I have lost the ability to fast charge. I have a factory LG charger and a fast charger 3.0 in my work van also, both chargers would charge my phone in a blistering fast time before and say "fast charging" on the screen but since the reset they both charge rather slowly and just say "charging". I haven't changed anything as far as leads or chargers go.
Is there a setting somewhere on the phone that you have to enable for fast charging after a factory reset?
Thank-you
Hi,
long story short: I connected my Z5C to a bad (apparently, I don't want to test ) charger and now I have some strange issues. Is there any change that my h/w isn't fried?
Full story: As I said I connected my Z5C (newest CyanogenMod provided here) to a charger and it instantly did a hard reset. Afterwards it did turn on and continued to work for some time. As I was on the road at that time I could not charge it elsewhere and later that day it ran out of power. When I tried to charge it with a known good charger some days later, it did not boot. I suspect the boot process to healthd or whatever draws this cool animation takes more power than my working but small charger provided.
It did charge at my laptop, especially when I put it into fastboot mode.
Now thats where I am stuck; the phone won't turn off completely and keeps rebooting when I turn it off (via os menu or hard reset, no chance).
I can charge it after it runs out of power (managed to charge to 100%), but it won't charge if I unplug and replug it. It is not recognised by a pc after I reconnect it one or two times (checked with device manager and lsusb), only chance to get to fastboot or flash mode again is drain the battery to 0%. It does show a loading animation and I can boot into android from there. Battery drain in Android seems to be a little higher than usual (100 to 0 after 2 1/2 days of pure standby without any radio stuff on).
I have already reflashed the original Sony firmware and erased everything that came to my mind (cache, data....).
Any hope that I did not kill some piece of hardware?
Thanks for your answers, any help appreciated
tell me more about your z5c's software, why you mentioned Cynogenmod? did you flash it with cynogenmod?
seems to me that z5c was running on custom rom and did not support fast chargers and bricked your device!
if that so, try flashing it using flashtool with original stockrom.
i don't wana go in to details however there is possiblity that battery.sys file is corrupt and atleast I was never able to fix my LT18i when it got bricked and battery status use to become zero in 2 seconds and android keep rebooting, later it got silent for good! no charge no nothing and i still have the device sitting. I was running it on coconut (cynogenmod) when all this happened!
Thanks for your reply.
The charger was no kind fast charger, just a common 12V to USB adapter with an output of 800mA (when it worked). I was running CM 13 when I connected it to the bad charger, but as I mentioned I have since then reflashed it with Stock ROM. No real improvement.
I have continued trying and I found out that the device seems to believe it is still connected via usb.
Code:
cat /sys/class/power_supply/usb/present
gives me "1" with nothing connected, can you check if this is normal?
The file is -rw-r-- r--, would changing its value change anything or is it just some kernel thing (can't check, don't have root permissions now as I flashed Stock ROM)?
Also after I charged it on my PC today it still shows me the notifications for USB connection and adb (I can add a screenshot if necessary), also looks like it still believes to be connected.
It seems I found the solution: I was playing a bit with a USB-OTG adapter (the ones to connect regular usb devices like keyboards or storage to your phone). After I connected a USB keyboard I tried (just for fun) if the Linux "Magic" SysRq hotkeys were enabled. So I did press Alt-Print-o, which is the Linux hotkey for "turn off now". It did not turn off, it also stayed off (no instant reboot). After I started the phone again it also properly turned off via the power menu!
I will have to test whether the charging issues are fixed, too, but as far as I can tell the problem seemed to be something software-related
Sadly did not work for long. I think I will go for official repair, think this is still cheaper than buying a new phone (after completely killing it with some DIY "repair" attempt). This annoying brick simply does not turn off, no matter what I do (apart from draining battery to 0%). Guess its my fault, still to afraid to try that broken charger again.
Hello good day for all, as the title indicates I have presented a problem after updating Android Nougat this officially with smart swich, after this the loading process stops when it reaches 80% I can leave the device all the charging night and does not exceed this percentage, this clearly with the original charger and cable and the only way that the device charges 100% is by slow charging via USB cable to a PC.
I have installed third party rom almost the majority that there is in the forum and the problem persists and the only solution is to return to Android Marshmallow there the device loads in a normal way and 100%
Additional to confirm clarified that I always use the original charger and cable and likewise try to calibrate the battery with the hidden menu that has the phone, letting the phone download completely 0% and then loading it with slow charge and restarting it several times to calibrate also this way the battery, additionally I have also done the factory reset and I have done in the recovery wipe and cache clean and still the additional fault persists if I connect it to the PC it detects it in a normal way so I ask for your valuable help to try to manage that failure.
Thank you.
