Fastcharging overheats - LeEco Le Pro3 Questions & Answers

Hi,
as the title suggests my phone (x722) gets really hot during fast charging; i've tried disabling fast charging but it doesn't do nothing on Aicp 13.1.
I'm currently using the included charger and cable, connected to the socket via the gearbest adapter that shipped with the phone. Ambient temperature is 26C (79f).
I'm also using the cover that came with the phone.
Should i buy another charger and cable? To avoid the excessive heat i've now switched to an old Samsung 5v/1A charger, with the provided cable.
Thanks!

Bump

Stop using the stock charger. This is mentioned regularly. Also, Samsung's implementation (adaptive charge) is based on QC2.0, whereas the stock charger charges at rate of 3800-4xxxmA. Naturally it will run warmer.
However, with all the reports of it causing the phone to shut down overnight, burnt USB ports, and QFIL I don't understand why you'd touch it at all.

Slow charging

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.

Charger Disappointment

Any one Disappointed with the charger they included with the Pure. The non removable cord just sucks and a poor choice in my opinion
I'm more disappointed at the size of the wall wart. They could have made more friendly to other power strip users.

Pretty sure they did that so you couldn't just stick any usb charging cord in their...it'd most likely fry it.
The disappointing part is the my other cords not working with Android auto. Luckily I have a nexus 6, and the cord with its charger works.

I guess that could be a reason but highly doubt anything would be fried. Ive been using a nexus 6 turbo charger and before that i was using a note 4 charger to charge multiple android/apple devices without issue. This just limits what i can charge on a single charger now need a second lol

If you plugged in a charging cord that can't handle the increased power it sure could fry the cord. I feel ya though...it would be nice if it were a USB cord.
I'm glad it looks different.... My son knows NOT to plug his HTC M7 into this charger.
I can see if this was someones first Android, the lack of a micro-USB for data would be frustrating, but I have about 5 of these in my desk drawer and throughout my house and office, so it doesn't bother me.
Also having a fixed cord means you don't pulg some 'slow' cable in and not get any benefits. Out my 8-10 micro USB cables, only 2-3 get a decent charge speed.

If a device that does not do Turbo Charging is connected, the charger should automatically adjust and charge it at regular speed. At least, that's what it is supposed to do. The Turbo Charger is supposed to be the single charger for all types.

I think the reason they made the cable fixed is because a lot of cheaper usb cables use very thin wire gauges. Since this charger puts out a lot of current at varying voltages, it's very possible for a thin cable to overheat easier and catch on fire. And my guess is, they didn't want to take any chances
How do we determine if turbo charger is ongoing? I mean are there any indication? Coz when I plug in the TurboCharger that comes with it, sometimes TurboPower Connected shows at the bottom of the screen, sometimes not. Then when I check it on the Status, it says Charging over USB, not Charging over AC? Could be that my unit is defective? perhaps the charger? or the battery?

I've got the same issue going on. My replacement from Amazon will be here Tuesday so I'll have time to mess with both and see if its the charger or what. Currently my turbocharging is hit or miss.

I have this issue sometimes to. So if I need to know if im charging at turbo I use an app from the app store to see if states I'm turbo Charging or not. In the Charging screen it will say "normal or Turbo"

You can use a USB voltage/current indicator device to see it directly. I use one that displays voltage and current simultaneously, it cost about $10 on Amazon.
The Qualcomm QC 2.0 (which Motorola terms "TurboPower) spec is 5, 9, 12, and 20 volts, with up to 2 amps plus at each voltage. The QC 2.0 chargers I've tested including the Motorola charger included with the XT1575, range up to 9V and about 2+ A at 9V, with the higher voltage/amperage when battery is discharged to a lower SoC.. Haven't seen 12V or 20V, I think those only come into play when battery is discharged to nearly zero SoC.
Agree the reason the included charger has cable attached may be to ensure adequate wire gage. Too-thin wire will increase voltage drop across cable thus lengthening charge time in higher power modes. But the design here uses higher voltage to keep current down around the same 2A max current of USB 2.0 chargers, so cable heat will not be a problem with any old USB cable.
I will attest to the benefit of QC 2.0. I thought it was a useless gimmick until I started using it. It does effectively compensate for mediocre battery capacity.
My "Turbo Charging" icon displays properly, but doesn't charge very quickly if connected to a cheap extension cord.
Plugged into the wall, the charging Stull doesn't impress me that much

It's defective. Call moto they will replace it for free. Just have to send copy of purchase receipt. Had the same issue.
The charge rate depends on how discharged the battery is when connected to charge.
More discharged (lower SoC, State of Charge) will drive a higher charge rate.
As to the difference between this Motorola TurboPower (aka Qualcomm Quick Charge 2.0), vs. other phones:
I've measured up to 1.4 amps at 5V nominal on other phones, that is about 9 watts charging power. That is max charge rate, with a very discharged battery. As the battery charges up closer to fully charged, the charge rate (power) is reduced. Total charging time from fully discharged to fully charged would be about 4-5 hours, give or take, for a typical cellphone battery.
For comparison, the QC 2.0 measurements I made with the MXPE: Up to 2.2 amps at 9V nominal with a phone battery discharged to about 40-50%. That works out to about 20 watts charging power. As with other Li-Ion battery charging systems, this also declines as the battery approaches fully charged. Total time to charge, from fully discharged to fully charged will be about 2-3 hours, give or take.
So the marketing claims about QC 2.0 are about right: A 75% improvement over conventional charging systems.
The biggest gains come when charging batteries discharged to lower SoC. If you are comparing charge rate/time of batteries discharged to only, say, 70-80%, you will not see as much of a difference with QC 2.0.
I'm not a QC 2.0 marketing shill, mind you. I pretty much ignored it, before buying the phone. But for this phone, QC 2.0 actually does a good job to compensate for the mediocre battery. I can run the battery down to 40-50%, put it on QC 2.0 charger in my car for my 30 minute commute, and it is charged to around 80+% when I arrive at my destination. There are a lot of QC 2.0 certified aftermarket chargers out there too, Qualcomm did a lot of work on the front end as part of bringing it to market. (Just make sure any AC charger is UL listed or equivalent, if you care about safety.
Caveats on cables: The cable does make a difference at higher charge rates. Thinner gage wire will impose a greater voltage drop at higher current, this will reduce power and thus increase charge time.
Typical USB cables are AWG 26-28. You can buy 20, 22, and 24 AWG USB cables. Some cables advertise heavier (22-24) gage wire for the power leads with standard (26-28) gage wire for the data leads. The aftermarket QC 2.0 AC chargers I bought listed their included cables as 20 gage.
Get the heavier gage if you want full QC 2.0 charging.

Faster charging using USB TypeA

Hello XDA members,
I would like to ask you if you know a if it is possible to charge my Nexus 6P with the usage of my USB 3.0 OTG Cable and a Male-to-Male classic USB 2.0 Cable ...
At the moment my phone is charging with 0.2A maximum, even with a 2A wall charger ...
The only working charger is my classic Nexus 6P TypeC-TypeC ..
Have a nice day,
George.
I don't know about the first part of your question regarding the OTG cable, but can say that any compliant USB-A cable is limited to 2.4A in the absolute best of conditions. You may find an answer in the Accessories sub-forum where most of the charger and cable discussions are.
When you say your phone is charging at 0.2A using a 2A wall charger, that may be normal. Are you measuring the input current when the battery is completely dead, or closer to full? The phone itself limits the charging current by it's built-in charging profile, so it will only accept full charging from 0-40% then taper off to zero as it approaches being fully charged. See the 6P charging graph. Even with the stock USB-C to USB-C 3A charger, you're only getting less than 0.2A amp during the last 10% of charging. Not only that, but the phone keeps accepting even less current for almost an hour past 100%.
Here's a solution for my problem, first let me you clear the problem/ my case:
I want to use my Nexus 6P as a Android desktop computer.
I already found a way to charge and use multiple USB devices (using a USB hub)
for more info check out General Section I have posted a guide so you can do it too.
I also bought a chromecast because sadly we cannot use HDMI, there is no DisplayPort on our Nexus 6P.
Everything were working perfectly except the fact that my phone was discharging, while actually charging with a 2.0A USB 2.0 wall charger.
Here is the solution:
FInd a way to power up a 16V case fan (those fans that are a inside your desktop case) and make a stand for your phone, COOL YOUR SNAPDRAGON BABY!
Phone is still charging slowly, while the temperature is at 24Celsius stabilised!
Have a nice day,
Have fun with this it is suuuper cool gadget-like creation if you consider doing it too,
George.

25W charger

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
Sent from my XT1580 Hammer using Tapatalk
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.

Observations on charger port burn out problems

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!
