I love my G2 and have been running it stock unrooted for almost a week now but I'm confused about the charging speed. I have two LG phones, the G2 d800 and Optimus G Pro e980. My G Pro is rooted running a custom 4.3 Rom.
My issue is when I plug the G2 to my computer using the stock cable it came with from the store it immediately goes to slow charging mode. It'll take hours and hours to charge up from about 50%. With the same exact cable setup when I plug my G Pro it only takes about a hour and a half to charge to 100% and that's from about 15 - 20%. This makes me think it has nothing to do with the cable I'm using. It's plugged directly to a USB 3.0 port in the back of my computer. If I use the wall charger with the same cable the G2 charges just fine. idk.
My G Pro used to have this issue but after going custom roms it never had that problem again... it always charges crazy fast now. I don't really want to install custom on my G2 right now I'm actually enjoying the stock experience again I was missing it with my G Pro.
Anyone else have this issue?
It has everything to do with cable, and kernel/binaries. USB 3 and steady voltage requires a thicker power AWG. The kernel and or binaries limit it to slow charge per voltage for safety and stability. The phone states it's USB 3 capable, but I assume only on the power side, as the 5 pins on the phone isn't enough to handle the full data speeds of USB 3, it requires 9. If you look inside the port though, on the phone, there looks to be extra pins.... maybe LG plans to release a special USB 3 cable? Just speculation. http://forum.xda-developers.com/showthread.php?t=2460881
I noticed that when stock, or using stock-based ROM's it goes into slow charging mode if you use anything other than the stock LG charger and cable. When I install CM10-11 it charges fast on all cables.
It does not. Use a mA reader. The notification is just simply removed.
hmmmm now I'm wondering if the battery level my G Pro is showing me is accurate or what.. the G2 battery lasts considerably longer than the G Pro when both say they're fully charged. I'll try new cables and maybe finally get a second battery for my G Pro and see if it still charges as fast as it's saying. Thanks for the replies guys. :good:
They are both charging at the same rate. The G2 just has a higher capacity. The notification seems to pop at 1A or lower. You're gonna need a high quality 24 AWG or lower cable to draw high amperage from the phone. I posted a working one from newegg. The stock G2 cable will also fast charge it from the USB 3 port (if the port is configured correctly with good drivers for charging switch). The problem is voltage droop in combo with this phones kernel or binaries. There isn't much getting around it on the USB port. A quality cable will counteract this with less droop on the bottom end.

I get slow charging with the original charger can anyone help me? Thanks
If the phone is off use gsam battery to determine What's using your battery as you charge
Sent from my VS980 4G using XDA Premium 4 mobile app
Would that help if I get the slow charging icon in notification bar?
Even just posting on here it's discharging not doing anything else
AFAIK, the G2's definition of "slow charging" is any time it isn't getting (close to) a full 2A from the charger. This doesn't mean the phone isn't charging, or that it's going to take an excessive amount of time to charge. Other chargers will work fine. The Snapdragon 800 CPU supports fast charging, but the opposite of that isn't necessarily "slow".
One thing to watch out for is temperature. If the phone/battery is warm, unplug it for a little while, and maybe even turn it off to let it cool down. If it's too warm, it won't charge very well. I found this out the hard way recently when I left it on the original charger overnight, and it still hadn't gotten to 80% by morning.
Right OK thanks but should this really happen with original charger?
original cable too?
Yes original everything
Mine doesn't show slow charging if I use the original cable. I tried another cable with original charger, and it shows slow charging.
It seems like the "slow charging" depends only on the original cable which comes with the G2. I have used another USB cable with the original G2 wall plug and I still receive the indication of slow charging.
Why would LG do that? I could understand that the wall plug has to deliver a certain ampere but it shouldn't depend on the cable... (only apple would do such thing )

You have to remember that the 1.8 amp charger that comes with the phone would be considered a rapid charger for other phones. Which means the cable would have to be able to carry that amperage. The cables will always matter. If the cable is unable to carry the appropriate amount of electricity, a bigger, better cable is needed. It applies throughout electronics, not just to apple.
Hi,
I have a Note 3 N900 version. & I am on Love 89 2.2 Custom Rom
Thing is, My battery charge has suddenly gone down.
I mean it was working pretty well but since last night...it charges real slow.
& the Phone is not even a year old so m confused as to why this is happening.
I checked the charging Unit with Charging Report available on the Playstore & it shows as 300 for both Current & average.
May i know what should be the default charging unit.
Is this the cause from the Rom or the USB cable?
Thank you
Try charging it with an other charger and see if it still charge very slowly... (if you dont have another usb 3 cable, normal microUsb that all other android phones have, fit into the right part of the note3's usb 3 port)

Hello there developers,not sure if I'm posting on the right place but I have a really big problem. My new Pogo Cable arrived and I was so excited to use it,but my happiness didn't lasted fort too long. The problem is that the Tablet while charging with the Pogo cable is either charging slow ,or neither at all. This issue is available for both Lollipop and Kit-Kat,have upgraded an then downgraded with the hope that the issue will be solved. The original Micro -Usb cable works good but with the Pogo Cable in the Battery Monitor Widget it appears "Discharging" and "AC Plugged",and the charging rate is booring slow. Had the idea to measure the Voltage and the current Flow with a multimeter and got the surprise that while the voltage is 5.12 V the amperage is 0.12 A ,while the original charger pumps up to 2 Amps. Could this be the issue? Is there some electrical switch that should open and release all those 2 Amps or is this Cable a Hoax or something that is not fully functional? Thanks in advance,hope that you guys will enlight me somehow!
I've no idea if this is related but be aware that having your pogo plug connected while also having anything connected to the microUSB will stop charging. The charging icon (lightning bolt) will still appear but that I'd a false indicator. This limitation is due to the Android kernel and is present in all versions of Android.
I exclusively use a pogo plug to charge my Nexus 10 and it has always worked on all versions of Android including 5.0.2 which I'm on today. For me pogo plug charging has always been about 25 percent faster then USB charging.

My experience is exactly the same as 3DSammy reports.
well my warranty is expired so i Decided to "surgically" dissmantle my Nexus 10 in a heroic attempt to find the cause and I have made a breakthrough (or at least I tought so). I got another Pogo cable ,and this one was good,the voltage was exactly 5 Volts measured and the Amperage that I got was 2.21 Amps measured with a 6 Ohm fuse,all these values where from the original Samsung charger. All things good,but the Tablet is still not charging at all,the same Lightning animations and even after 3~4 hours still no charge at all,and this is Lame in my opinion. So after opening the tablet,I got the idea to short the 3 and 4 pogo pins together,and assumed that this will draw all the power that the battery needs to charge,the idea was working i got 20% more power draw than the usb cable BUT for only let's say Half of hour ,and then the same old story,battery was discharging but the lightning animation was on. This is not so good and my suppose is that the Power Management iC from the motherboard is some how not managing the Pogo charge at all :laugh: so my next idea is to wire the charging Pogo pins directly to the battery and hope for the best. Regards! :good:

I've got one of the original n10 from first day of issue. My battery is going to hell after being used and charged every day for the past couple years. It's been on/run everyday since Dec. 2012. I have always had a problem charging while using it. My display is always set at about 1/3 bright. When my battery drops to critical, I plug in the pogo and usually put it in sleep mode to charge. It will quick charge that way.
If I still need to use it at critical battery level, plugged into the pogo plug, it maintains power and possibly gives it a very slow increase in charge. Almost none noticeable, but will maintain power level (unless tons of graphic, camera or movies along with full bright screen).
I've just taken it for granted that this is how it works. Pogo plug will maintain battery while using and will switch to quick charge once put into sleep mode or powered off. It's always acted that way, so I have never known anything different.

Well I'm sure about what did you said,but in my opinion this is a marketing bulls$h*t. Why would I use that Pogo cable if it's role is to charge only on sleep mode and powered off?I ordered because I thought that like the instructions of the pogo says:" it will charge the battery even when you are using it for movies and browsing,being more handy ,because you have the micro USB port free." I play games ,I surf the web,so my tablet is hooked up to a USB hub so I have connected a mouse,a keyboard and a game controller,so my USB port is full,and I hoped the pogo will help. Charging only on sleep is equal to zero for me,I need live charging,in the same time as the tablet runs games and other stuff. In my opinion this "glitch" should have been told on the pogo site,so I could full understand this cable and it's role. Shame on Samsung,30$ .for nothing! Thanks for the help!
i heard the battery get totally broken after one year of using the original 25W charger , what is ur experiences ? does ur phone over heat too when charging does it get to 50-60 C degrees?
I've been charging mine with the turbo charger since day one, it's been fine. There is technology built in to monitor the battery temps and ramp down the charge speed as the battery gets full. I've had my phone for 16 months now.
Max temp I get is 42-44c

same here : 15 months with my MXF the 25w turbo2 charger.
Battery never go over 45° in charge, battery life still as good as the first day
In my car I have the Moto 25w charger. With navigation and other apps running the temperature rises to about 46 degrees. At this point the charge rate drops. Only if my telephone is at the cool air and out of its cover does the charging rate remain at the full turbo charge rate

Not so much that the battery fails. The connector (which is kind of crucial for QC 2.0/3.0) or the charge controller craps out. Battery's fine. Was fine when I did my swap out for charge failure. It's not the battery, which people incorrectly presume is the problem- the charge system is a feedback loop process running in the background while the OS is running. When you're dead, down, no charge in the battery, the device only draws USB 2.0 power levels, 500mA, until the OS can come up enough to manage the charging. Part of the reason they do this is because you're using a USB connection to charge with and unless you've got the 1.5 A USB charge slot or an AC charger with the ability to source up to 2.4 A of juice, trying to pull that much current will wipe your USB port on a PC/Laptop/etc OUT. This is just with traditional charging. Turbo/QuickCharge charging is about raising the voltages over the USB 2.0 lines on a cable to up to 12v as opposed to 5, to allow you to jam a bit more current through the lines and to the device, effectively doubling the power being fed to the charge system. Problem with that is that you REALLY need the OS up and running to manage that. It requires info from the Charge Controller chip that is handshook from the charger.
If your charge controller is damaged, or if the cable doesn't have clean data and power lines, it just simply WON'T WORK. It will just USB mode charge until you fix the "problem"- either of which requires Lenovo to re-work the board...if it's even possible to fix. USB charging takes forever with this class of device- because the battery is a huge tank of juice compared to the devices of old. So it "looks" like the battery got "broke".
Having said this, there's about 20-40% of the units out there, depending on the crowd you listen to, that have a defective charge controller system and the phone flat-out won't ever go into any mode other than USB.
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.

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!
