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....
Hey guys. I've been lately moving around on AOSP/CM roms, then TW rom, etc... and lately I have noticed a problem: no matter what cable I use, my phone will only charge with 350-450 mah. I noticed it was charging incredibly slow so I bought the app Galaxy Charging Current to tell me every time. I tested out the original usb 3.0 cable that came with the phone, 2 other usb 3.0 cables that I had from external hdd and about 5 or 6 usb 2.0 cables, most of which I used on other phones and they always worked like a charm. Only ONE nokia micro usb 2.0 actually charges at 1.200 mah, all the rest as said above, 350-450... My last resort for making them work is the kernel fast charge option, to upp the usb 2.0 cables to 1000mah as maxed allowed in synapse (back on tw, using the KK Explorer kernel v1.8, same one I used in the past with no problem whatsoever), but it is still bugging me since now all my usb 3.0 cables are pointless and cannot get to 1800-2100mah charging speeds that I once had. I strongly believe it is a software problem, I just don't really know where to look... On CM with other kernels I had the exact same problem, so I rather doubt blaming the kernel that worked for me in the past... Help please, any idea would be greatly appreciated
Heeeeeeeeelp please!!!
Hi Guys, ive been part of the HTC One X scene and now i am getting an s4, question is i hate Touchwiz with a passion!! so i want to use an AOSP rom, my question is what is the easiest one to use and are modded kernals a good idea with this phone? regards,
I use Danvdh's GPE ROM. It basically converts your existing S4 into a Google Play Edition S4, but with some subtle enhancements. Being a GPE ROM, it also has the advantage of using Samsung libraries for its hardware, which makes it run more smoothly than the AOSP alternatives that use reverse engineered drivers.
I had been leaning to that Rom, what about kernels any that actually make a noticeable difference? I keep seeing fast charge pop up ?

Use the Googy Max kernel that's included, or use the more up-to-date Hulk kernel variant of Googy Max. Alucard's kernel reportedly has a battery drain issue and the stock kernel introduces random reboots. As for fast charging, I've not gone through every post in that thread so if there is a fast charge option I'm not aware of it.
Is there any idiots guide to do it? Lok

An idiot's guide to install the ROM? Root, install a custom recovery (TWRP recommended here), and install the ROM through recovery. The various kernels and ROM options are all in the zip, as it uses Aroma installer.
Easiest way to root? Still on kitkat if that makes a difference

CF-Autoroot. There should be a thread for it in S4 General.
I actually find the CM12 optimzed builds to be a bit snappier than GPE. But GPE is more stable and bug free. I had several problems with the latest CM12 builds.
You can always change roms afterwards. But I keep coming back to GPE The only downside is that there is no ktoonsez kernel for GPE 5.0.
It's an awesome kernel and the only one, that I know of, to offer GPU Overclocking.
Alucard and Googy-Max kernels are great too.
Fast charge is designed for USB. The USB current is lower than the AC current. This means that the phone takes a lot longer to charge via USB.
Fast charge substitutes AC to USB. Meaning that it will charge via USB with the same current as AC.
I was thinking of the rapid charging devices like the Nexus 6 have, where you get 50% power in roughly a half hour. Glad someone around here can keep me straight.

Well, it was mainly done to increase charging speed via USB, I think.
But you can also increase the current on AC charger. Which means it charges faster, similar to what you said.
I don't know what the default is on touchwiz stock kernel, but Googy set it at 1450 mAh for AC.
Alucard kernel comes with 1900 mAh for AC. Which means it charges relatively faster. Look at it as "Overclocking" your charger
But it may also reduce the battery's life.
Googy and Hulk allow you to set the AC and USB voltages, so I left USB alone but set AC to 1900. Its unlikely that battery life will be adversely affected by ramping up the amperage of the charging circuit, unless the battery gets exceptionally hot (it doesn't) in the process. The stock charger won't be damaged by doing this as the charger is rated for 2A in the first place. Third party chargers, as long as they're rated for 2A, won't be damaged. Smaller chargers will eventually fry.
I leave it at 1450. I'm in no hurry. Especially when I'm gaming
Hi friends
My device
there is the problem of slow charging
The current value 304-500maH
I tried all versions. V30a,V30b,v30c,v30d,v30e,v30f all the same problem
All transactions did. Wipe data factory and wipe cache :/
Thanks...

Hello friend, whenever you plug your device in USB port or a less powerful charger, it will show as slow charging. Use a 1.8A, 2.0A or more output charger to charge your phone.

Kitkat 4.4.2 no problem 1610 mah
Just lollipop problem
Hi,
I have the exact same problem. I recently upgraded my LG G2 (EU version - Dutch) from KitKat to Lollipop (5.0.2).
My car charger and wall charger (both 2.1A) were able to charge my G2 in a fast way under KitKat.
But now under Lollipop, these chargers have become useless (they charge very very slow).
My battery is draining while using GPS and media streaming in my car with car charger attached (whereas with KitKat everything worked fine, and my battery gained extra power...)
Only the official LG OEM charger can charge my phone fast.
How can I fix this? Somehow LG verifies if the official charger is attached, and otherwise he limits the charging?
I hope you guys can help me out?
Thx in advance!
Possibly a temperature issue

Few days ago i was exactly in your shoes. I came from a custom rom (cloudy g2 2.2 with dorimanx kernel ) to the stock lollipop 5.0.2 . While being on the lollipop rom the device could not hold a charging rate above the 350-400 mah. Through some testing i found out that device needs to be below a certain temperature (for me at least, it was around 60 degrees celsius ) in order to charge at a 1600 mah rate.
I have tested some stuff during the weekend, but in my case, it isn’t temperature related. Even when the battery temp is low, the 2.1A charger still charfes very slow, while the OEM chargers goes full speed. So battery temp doesn’t affect my charging speeds.
Even during the hot summer days, my car charger was able to charge quickly while using KitKat.

Nothing that was posted on this thread is correct, lg's lollipop kernel is horrible and only slow charges. Thats why Dorimanx when build his kernel had to add a feature that allows fast charging.

I read somewhere that from the lollipop version of android and onwards , a certain " code " has been implemented in the stock kernel (and as result every stock based kernel out there) , that checks whether or not the original charger is being used or not. Might be false, might be true ? who knows? i only have the original charge so i cannot test it out. On the other hand, many custom kernel developers including Dorimanx as @Eminemiero says do actually have a workaround implemented on their kernels to give the possibility to achieve full charging rate even on 3rd party chargers

I do have the original charger but only on stock 30b i think it was i could fast charge. In any other rom i had to wait hours to get full charged.
Its strange, all i know is that lg ****ed it

same issue.
try dorimanx latest kernel. If you are not a fan of custom kernels, then just install it and dont touch nothing on its settings
Try Llama sweet kernel.
Install synapse from play store.
Install UKM zip from recovery . find in main kernel thread.
Open synapse go to misc . enable fast charge . set it to 1200 Mah . you are done
Don't forget to nandroid backup before.
I'm a n00b when it comes to flashing custom roms, custom kernels etc (never did it before).
What is the easiest way for me to achieve the fast charging back on my LG G2 device with the other chargers?
Maybe some step by step instructions?
Can you use an alternative kernel on the original LG stock rom? I'm happy with the stock rom, except for the charging issue i'm facing...
many thanks!!
I have read from various sources about the Leeco 727 dying a premature death due to burn out of the charger port. Some theories attribute it to bad Leeco supplied charging adapter or cable or faulty motherboard.
I tried a bunch of different wall adapters and cables to see if I could make some sense of it. What I noticed is that only with the Leeco supplied unit and an Anker dual port unit do I get any semblance of fast charging. There is no indicator on screen. I can only go by time observation.
Charging with other fast charge adapters seem to charge at a slower pace at 5 volt. From what I can see using a USB port tester is that when something charges at fast charge, it charges at 9 volt. I used a Samsung adapter and one from an orbic wonder which are definitely fast charge capable. They charge my old Motorola G4 at "turbo power" and a Note 4 at "fast charge".
I bought a unit from Allmaybe that has visual lcd of power consumption and it clocked down to a lower voltage after tripping the overpower indicator.
Maybe we need to throw away the Leeco wall adapter. It's possible that either it or the phone is drawing too much electricity for the port to handle.

Their threads on this.
Sent from my LEX727 using xda premium
A device like yhis Xdragon USB voltmeter might be helpful in debugging issues with charging.
Right now I am connected to a Samsung adaptive fast charger that can pull 9 volts but currently just pulling in 4.78 volts and about 700 mAh. At that rate will take about 5 to 6 hours to fully charge the 4200 mAh battery in the Leeco

The charger is fine, it was built according to qualcomm specs: https://www.qualcomm.com/media/documents/files/quick-charge-device-list.pdf
The Issue is that alot of phones were sent out with bad cables.
I don't think that it's just the cable.
I have been seeing hard shut downs while charging at night. It's not consistent so I am just going slow I suspect that the phone is shutting off to prevent overcharging the battery.
I have 2 x727 with asop extended 8.1 and blackscreen kernel 4.9 installed
I replaced the original LeEco USB C cable with a genuine Samsung USB C cable per the recommendation of other threads. "no change still shut down while charging overnight"
I suspect that it is a kernel battery issue so I backed up in twrp and I installed the regular version 4.9 of the blackscreen kernel. "no change the phone is still shutdown occasionally while charging overnight on a original leeco charger with a Samsung USB C cable"
So now I am trying both a Samsung charger and Samsung cable. I should revert back to the twrp kernel backup but blackscreen kernel is just too awesome!
The Samsung charger only outputs at 5.3V @ 2.0A
The LeEco charger outputs at 3.6v to 8v @ 3.0A or 12v @ 2.0A
I'm pretty sure that the problem is a software issue with the quick charge 3.0 voltage controls in the rom itself but I haven't gotten a log of the shutdown yet to confirm that because I haven't rooted the phone. The phone was getting uncomfortably warm when charging.
I'm betting that with the Samsung Oem quick charge 2.0 charger the phone will work properly without shutting down overnight.
I'll update this post with my results.

Have you tried simply reflashing the correct firmware?
I too have a X727 and had similar issues in the past while using a firmware designed for the X720, and alot of of Rom's come with the X720 firmware.
Try flashing the kernel from my Google Drive link below and see if that helps.
https://drive.google.com/open?id=1qAJrM8bIfI190W9w2gKR97xVhA-2lrZt
Meh 2 phones same software with different results.
I still don't really know why it was shutting off while charging overnight.
But the problem hasn't repeated itself since I stopped using one of the LeEco chargers. So at the moment I am blaming it on a bad charger base or wonky phone charging circuit, not the cable.
I was thinking my problem was software but I had already changed my roms Kernel to the appropriate blackscreen kernel from the roms stock kernel and the problem persisted on her phone until I stopped using the one included LeEco charger on my wife's phone, it's charging fine on the Samsung 2.0 quick charger, and mines charging without issues on the second LeEco 3.0 quick charger.
Unfortunately I can't just wipe her phone without causing her problems because she is always on her phone.
Is the problem hardware related in her phone is my current question? Or am I tracking a bug in the software.
If the problem is that charger base it should have zero effect if I put her phone on the 3.0 charger that I am using. If it is her phones charging hardware that test could permanently brick the phone Fry the charge port or battery ect...
So I am going to order another x727 if I can find another new one on ebay apparently most of the new US inventory is gone and the price is being gouged on the last of the new ones. :crying:
That way I will have a backup so I can do that test and have a phone to use for development. That's why I bought this phone in the first place.
I'm pretty sure that the one charger base is the whole problem but I can't afford to test that theory yet.

You can buy usb voltage testers on Amazon.
If you happen to have a bad charging block just toss it, and buy a universally compatible Qualcomm Quick Charger. Such as this one: https://www.amazon.com/Charge-Anker-Charger-Compatible-PowerPort/dp/B016LO811S
Blitzwolf quickcharger and C cables. Bought 3 of each. All my charging issues disappeared when I bought them. Leeco supplied cable/charger are crap, why risk it?
FYI, I have experienced the condition where my charging stops randomly when using 2 different decent Samsung Travel model fast chargers. Stopped around 49% to 85%
Neither pulled in fast charging voltage-drawing a little under 5 volts and maybe 1100mah, as compared to 9 volts when connected to the Leeco charger.
Good point. Charger blocks are cheap phones aren't.
As addendum to this issue, after a year and half my charger port finally burned out. Probably abused the phone a bit and got some moisture in the port, maybe it was just a matter of time.
I was able to resurrect the phone though. The actual replacement board is available on eBay for $5-10 with tools. Hardest part was using a heat gun to remove the screen. There are guide on how to open up this unit.
One thing I will tell you I am that you don't need to remove the battery to get to the USB board.
Just another note, either hitting my phone with the heat gun or mucking around with the battery unnecessarily caused the battery to start to malfunction. Battery would discharge quickly and phone would shut off randomly. I replaced the battery with some cheap replacement from China, cost about $16.
Also replaced the screen because I tore the ribbon cable by accident. The screen cost about $13. Definitely cheaper than an iPhone replacement!
