Hi all.
My Nexus 7 is flashed with DU 5.0.2 and charging is very slow. This was also the same when I had XenonHD flashed. It charges so slow that it discharges faster than it charges. I do not know what to do. I heard about flashing a fast charge kernel but heard flash charge was only for usb devices like laptops.

I noticed lately that my N7 has been taking forever to charge. And this is with the supplied stock 2A charger and cable.
I'm flashed AOKP Milestone 1 with its stock kernel, could the ROM or kernel be the problem? I also turned the N7 off to charge and after an hour, only ~15% was charged.
I'm not sure if this problem as always existed as I used it sparingly in the past but within the alst few days I found myself using it a lot and wanting to charge it fast.
Cable suck.... Change it....

Are you using a generic micro usb? If so that's the problem. use the Asus cable that came with it, or any other good quality cable.
Did you use a USB extension cable? If I use one, my nexus charges very slow.
I think the Nexus measures the resistor-value in the cable and if it doesn't have some specific (low) value, it just loads at 500 mAh. Or it does somehow read out the ID-Pin of the cable....
Wondering if anyone notice how slow it charges when it is connected to thru PC using USB (using original USB cable)?
I know it was not charging very fast when it was on 4.2.2, but 4.3 it is really slooooooooow...My N7 is pure stock 4.3 and so does its kernel.

placebo?
were you using usb fastcharge on 4.2.2?
Unfortunately I am having similar problem with my nexus 7 after OTA 4.3; it charges so slow even though I plug charger in and try to use it while its chaging, device turns itself off saying please charge battery. How can it turn off when its already on the charger?

Has anybody heard of a kernel that fixes this? I love everything about 4.3 except that it charges sooooooo sloooooowwww!
I plugged mine in 5hrs ago @ 30% and it is up to 85% now... Ridiculous! This is using the original Asus charger.
Connected through PC only gives you about .5 amp charging rate. The stock charger gives 2 amps. If you aren't using the factory USB cable then most likely it is current limited and not applying full power while charging. If you are using the complete factory setup then whatever you are doing is causing the battery to drain faster than even a 2 amp charger can supply.

I have s3 Neo i9301i.. from 4 months.
Before it charged well and fast but now the charging is annoying.
It take a lot of time to charge (3-4hrs) and while in use during charging it charges about 1% for 10minutes.
I am on Ciro rom v2....based on motion v17...
Could somebody give a fix ?
Buy a 2A charger. It solved my problem

Change your USB cable.
My battery drains too fast, using my phone continually it can discharge in about 3 hours. I have installed FirstFlight N7 Themed V6 ROM and I feel the battery discharges faster than in the stock rom did. I installed Ampere app to measure how much current my phone was charging and discharging and when the charger is not plugged in it discharges at 460mA, is that normal? I bought a Samsung 2A charger and it charges at 600mA or maximum 700mA but I changed the usb cable of the charger and it charges at 860mA or maximum 900mA. I don't understand because it should charge at 1900mA but it doesn't, how does I reach that? I need to mentioned that I charge the pone directly in a wall, not in a usb port, and why does my battery drain too fast? I need help :crying:
Charging current is dynamic. You can't make it always 1900mA as it highly depends on current device status, USB cable used when charging, etc. Also, ported ROMs tend to drain more battery compared to stock one and it's normal and not an issue for those who enjoyed ported ROM.

Recently i flashed my phone to Evolution X 4.5
and my quick charge is not working
Is this my kernel problem?

Checked today with MI9T charger and working using latest EvolutionX.
Did you checked with other charger/cable?
I prefer to not use regularly the quick charge, pushing charging current to limit can reduce battery life.

yes I have checked with other chargers still not work for me
I don't know if I do anything wrong when I was wiping my data
Even I am also facing the same issue. After flashing Pixel Plus UI the charging speeds have gone very low even the normal charging speed has dropped a lot.
Earlier the phone used to get fully charged within 1.5 hrs and now it it taking around 5 hours for full charge.
Find and flash a kernel that supports fast charging and use the correct USB-C cable and power charger.
