I'm running:
GEN2
Rooted
ClockworkMod
Swedish Spring Android 2.2 with Gingerbread theme and circle battery
Suddenly after a few weeks of everything working fine, AC charging stopped working. USB charging still works perfectly, and when I plug the phone in it says it is AC charging, but the charge level barely changes - it can be plugged in for 12 hours and not gain or lose any charge. Also, sometimes but not always, the phone becomes very very slow, and sometimes the screen won't unlock - I have to unplug it, unlock, then plug it in again.
I've tried different chargers and cables and combinations thereof, I've tried turning USB charging off or on in Extra Settings, I've tried debug mode on USB or not, hardware acceleration on or off, I've tried charging with the phone off or on, screen on or off, I've tried charging it for 48 hours, the charge level never moves.
This is the closest thread I can find on the issue but it is a mix of problems, and they never find a reliable diagnosis or solution:

I don't care if it charges slowly, I'm thinking of trying to mod a USB cable to force it into USB charging mode. Anyone know how?
I far prefer this to re-installing because whenever I connect my phone to my laptop it immediately bluescreens, (despite a fresh Win7 reinstall), and I am lost on my gf's Mac.
These posts describe how to do the opposite (force AC mode) on HTCs:

Thanks enormously for any tips

Since I lost my charger and had to use a generic micro-USB charger, I have the same problem. USB charge works fine.
May be a problem with the USB cable, have you tried using another one?
(I'm on Ginger Stir Fry, but I don't think it is ROM dependent. )
Thanks for the thoughts. I've tried different cables and chargers and combinations thereof to no avail, hence suspecting something software and looking to mod a cable to force USB mode.
Please anyone know what PINs indicate laptop USB rather than AC USB?
How does my phone know to go into the (disfunctional) AC mode?
Thanks
I think D+ and D- pins (2 and 3) are connected. You would have to mod the charger. Or just use generic USB charger, like those from dealextreme...
I recently flashed my Defy with 3.4.2-179-2 CEE DEBLUR and it reboots every time I plug in my usb cable. It doesn't matter if it's connected to a PC or to the power adapter. Anyone have the same issue and know of a solution?
I did a google search and found someone complaining of the same issue but didn't see a solution.
More background:
I had an issue with my phone and when I went to do a factory reset I was stuck on the google screen. My power ended up running low to the point where I couldn't run the bootloader. I had to charge the battery manually with a battery charger and some wires. I monitored the voltage throughout to make sure the battery was ok. After flashing the new SBF I found that things worked fine except whenever I plugged in a USB cable it would reset. I put CM7 on the phone hoping it'd help but the problem still lingers.
I will probably attempt to flash another SBF or maybe reflash the existing one.
Does this problem only exists if the phone is fully booted or does it happen if you plug it in while booting also? Because if its happening while booting too maybe your usb cable is broken and theres a short in the cable that makes the defy reboot. Have you tried another cable? And what about plugging the cable in before booting the phone? Tried this already?
I encountered this problem occasionally before. Dunno why.
There's 3 possible issues here apart from software/firmware causes.
1) The USB cable might shorted.
- This can be confirmed by using multimeter to test the usb cable. You will see a shorting between to wire in the USB cable.
2) The Phone USB port might shorted.
- This can be confirmed by using another good/new usb cable and test it with multimeter.
3) Phone battery broken(happened when you charge it using wire and external charger).
- This can be confirmed by trying another Defy battery and charge it.
hi farsight,
upon further inspection i'm pretty sure the usb port is shorted because if i squeeze the bottom of the case the phone will reboot.
is there any way i could fix this? I've looked at some videos for the disassembly of the defy.
hi iregistry,
yes the issue occurs if the phone is fully booted and when it's booting.
quit risky la.. if under warranty, why not claim/RMA?
hi adie, i bought it new on ebay and i'm not sure how the warranty works on that.
[solved!]
after further testing I believe it was because the battery contacts were not as close together as they were originally due to me manually charging the battery. It must have been right on the very edge because it would work normally but just squeezing it would make it lose connection.
I used a pin to push the contacts closer together and hope this solves the issue. I've plugged in the usb and squeezed the case and so far everything seems ok.
IMO this is a poor design on motorola's part. the raised contacts on the phone are nice but the contacts on the battery are poor.
Thank you everyone for responding.
Had the same issue. Your solution worked on mine as well. Pushed the contacts on + and - in, and it worked! Thank you!
I had the similar issue. I had attempted to charge battery with external universal charger and looks like since then this issue where "phone would reboot upon unplugging the power source" started. Now as mentioned in this post, put the +/- pins bit closer and tried unplug and no issue observed so far.
Thanks. :good:
I too have the same issue. I tried to charge the battery with some direct USB.
Today I dropped the phone on my bed from 2' height and it got restart. But its quite surprise to see the effect of the USB plugin with the battery connector loosing up
I am thinking of putting a small alumunium wrapper on the +/- connector. Let see.
Hi there,
I have a big problem with charging my Galaxy S4. It only charges with my notebook USB Port, my AC-adapter does not work.
In the battery menu I can see that AC is connected, when I plug my adapter in. But charging does not work with my device.
Over USB I can charge slowly. This isn't a software problem, I have done some resets and firmware changes since the problem.
Maybe my phone got a little bit wet earlier. Could this be the problem? Can I fix this with changing the USB port part of the hardware?

Yes, I tried another cable but had no success
I dunno if I can ask it here, but i don't charge over usb, i mean it just "hold" the power level for me. Is that normal ?
Is your AC outlet working ?
Having issue where S4 only charges with USB and vibrates when using AC charger
I've been having some issues with my S4. I did recently get it a little wet, but it's working fine in all cases except charging. I have my phone next to my bed charging every night. I noticed it was dead one morning, but I figured I didn't connect the charger properly. The next night I noticed it was vibrating every 5 seconds or so, but the phone had turned off due to a low battery. Very strange behavior.
I realized that it would start charging, but it would stop between 1-3 minutes. The the phone would vibrate and not charge.
I've ready MANY posts from others with the same issue and someone mentioned their phone charges over USB. Seemed odd, but I tried it and voila, my phone charged perfectly. I have many samsung cables, none of which work. It's definitely not the cable. I can plug a samsung cable into my phone connected to AC and it doesn't work. I pull the USB portion out of the AC charger and plug into a computer and it immediately and consistently charges. The battery holds its charge as expected, so it doesn't appear to be a battery issue.
I've tried the developer mode options - no luck.
I've tried bending the charging prong - no luck.
I've tried blowing out the charging port with compressed air - no luck.
I recently got an update pushed to my phone (Sprint), but I don't think it was happening right after the update. Seems like a likely software issue.
I did get my phone a little wet recently, actually it was my young children throwing water at me.
I've read so many posts and nobody seems to have a good answer for this issue. Any suggestions are appreciated.
Hello boys! I have a very serious problem with my LE PRO 3. Since yesterday, the following is happening BUG: When I connect the charger, it does not load immediately. It only loads if I reboot the device. And if I take it out and put it back, it stops loading again. This also happens when I connect to the PC. The device only recognizes if I leave the cable connected and restart. With the headset the same thing. It only recognizes if I leave it connected and restart the device. I'm on the Cydrass Google edition ROM, and my device is the x720 version. I have already switched to other ROMs (LineageOs, Ressuection Remix, and even the Chinese STOCK ROM 26s, and the problem still persists!) Apparently it's a serious problem recognizing my USB port I do not know what else to do! Please, help me!
even first buy , do you have problem ?
To Vitor_147
Remember, if you change the stock original LeEco rom you cannot say "have a problem with my LePro3", it's no longer the original combo "LePro3" (hardware + software) so expect (and accept) anything (better or worse!) and report the defects to the rom developer.
Now some helping things!
Apart to clean the phone usb c port and to try a new usb cable, you can:
With the usb cable connected, switch the usb debug off (or on) (developer options) then check if your computer detect your phone.
Even if your computer doesn't detect the phone or your phone seems not charging battery, if the usb cable (and charger) is good in 99% of the cases it charges the battery even if not at full charge rate (expect a minimum 4 hours charge time).
Before to give up, the last try is to bring your phone back to factory conditions with everything (but everything!) under the exact conditions of how it came out of the factory, then you can start over there and have an idea of whether the phone has a hardware defect or if it's just a matter of software.
I hope you solve the problem, if you find the right solution please report it here, so other users can learn how to solve this problem! Cheers!

I already wrote this up in Omni thread, so I'll keep it short. I've also been experiencing this same issue for a while now, it first happened on stock rom, reboot solves it. Darko tried a fix in his eas kernel, seems to fix it (so maybe somehow kernel related). I believe it might be somehow related to the usb-c controller, cause I found cases online of similar issues with pixel phones (i believe the controller manufacturer is the same as in our phones). I actually know the exact moment when my problems first began, after I used my OTG adapter to connect a usb mouse. Few hours after that, the phone wouldnt charge.
{Disclaimer - this part is purely my theory}
I think it maybe somehow related to a safety "switch/fuse" of sorts, or something to do with static discharge or something similar, and here's why. I did a loot of trial and error since the first time it happened to me cause it scared the sh*t outta me, thinkin my phone is broken. I am vigilant about careful handling of usb ports and such, (ocd-ish really) so theres no way I physically damaged it, its not loose one bit, cleaned it out, tried wiggling the cable around anyway, has no effect, so I excluded the possibility of a faulty port/soldering. A few occurences to note
No1 - if I plug my phone in the charger first, and then plug the charger in the outlet, it breaks the port, I have to reboot to fix it. But plug the charger in the outlet first, then the cable to the phone - no problem. (Static discharge of sorts?)
No2 - since it started happening, the only way my usb-c OTG adapter works is if i first plug the adapter in the phone, and then the desired usb device in the adapter. If i try to plug the adapter in the phone w/say a usb stick already connected to it - no go, doesnt work.
Oh... I'm sorry for what happens to your phone! It's true the safest way to charge a phone avoiding current surge/spikes/shocks is to plug first the charger to AC outlet, then the usb c plug to the phone, then the usb plug to the charger. If possible, never plug/unplug the charger to/from the AC outlet if the phone is connected to the charger.
When the phone is full charged, first unplug the cable, not important which side first, then unplug the charger. If the phone is still charging, better unplug first the cable from the charger side to avoid micro spikes on the usb c port.
If you cannot obtain a normal behavior of the usb c port neither with reflashing the phone with the "qfil" system, perhaps a logic port of the usb c port is burned or simply in undetermined state, in the last case a total battery discharge may reset the logic port state and the phone can works fine once fully recharged. I'm sorry I can't help you better at this time! Cheers!

@orsonbear, thats my train of thought aswell, micro discharges occuring while plugging/unplugging causing the controller to freak out, or potentially damage the tiny connections (micro usb only had 4 wires vs 24! in usb-c). But I believe the problem lies somewhere on the software/firmware side, mainly because a reboot solves any issue I have. And also I just remembered, the first time it happened to me was a couple of days after I updated my firmware while updating to 19s, or 20s, cant recall precisely. Anywho, for me it's a minor nuissance, not like the OP who can only connect his phone once before rebooting (I can go for weeks before it occurs).

Yes,
I thought about letting the phone down completely, and see if that does not happen anymore!
Same problem here
Days ago it start happen, exactly how you say, i never change the stock software and it start happen randomly, I have to reboot to recognize anything that I plug into the USB c port, I try factory reset and change from 26s to 23s and it keeps happening so maybe I'm pretty ****ed, someone help me, in my country no one will fix the port u.u (sorry for my English).
Hellao! I'm having a very similar issue, charging works fine and the pc detects the phone but OTG and the audio on my headset is not working. Did someone of you find a solution to this problem?
1. x720, x722 or x727?
2. Where did you buy the phones? (Store names)
3. What kind of USB-C cable were you using? The one that came in the box? Have you used other USB-C cables and adapters to see if it works?
This could be hardware failure due to a lack of QCing from LeEco (just your average hardware issue) or a USB-C cable issue. It's ver. 1.0 on all LeEco Pro 3 models (right)? So I can't say it's the cable for sure. Has anyone attempted to take the phone apart to replace the port? do they even sell the port replacement?
Similar problem for me. About a month ago my headset stop working and the phone did not recognize it at all, tried with the adaptor to 3,5 mm jack and did not work either. Charging worked though.
Found a replacement chip with usb c port and ordered. Yesterday i replaced the charging port, but still the headset do not work at all, and connection to PC does not work ether. Charging still works as usual.
I ordered the phone from grossoshop 7 month ago with their rom. Tried this evening to upgrade the rom from 5.8.018 to 5.9.020, still grossoshop but no difference... It should not be a hardware problem as i replaced the type c port.
Should i try to flash another rom to see if there's any difference?
Any other suggestions?
Thankful for any ideas

Have you tried switching cables? Could you have broken a contact or something while swapping the port out? Have you tried putting the old port back in to see if the computer recognizes the phone with it? Unfortunately you're gonna have to try everything, even if opening it back up again is tough. LeEco phones aren't exactly known for their build quality. Are you x720? Well, flash whatever ROMs you can, I guess. Might as well try everything.

Yes, I have tried to switch the cables so no problem with them. Have not done a swap back again as the problem seem to be similar as before, so maybe a change to a different rom will be the next step for me. If change of rom does not work, maybe then I'll try to swap port again.
And yes, It's a X720
Thanks for fast reply.

Maybe it's not plugged in or attached correctly so the phone doesn't detect it. Sounds like a hardware issue to me, in all honesty. I once took apart my iPhone 5 to replace the non-functional home button and it wouldn't work no matter what I tried. I had to remove the battery, reseat it, and then attach the home button again. It finally worked after a reboot.
just report in on this thread, I as well recently purchased an x727 experienced the similar issue. Basically as described above no matter what roms i test is always have some sort of camera errors when charging.
sometimes charging doesn't work or camera doesn't work I have to reboot to get it to work. extremely annoying. I think it is hardware related.
Anybody else have a solution?

This my advice to anybody considering buying this phone don't why you will get zero support from letv.
I got luckey I have zero problems with phone .
I recommend spending more money and getting a supported phone by the maker.
If you do buy one buy it from Amazon where get a warranty on it.

Somebody fixed thuis allready as my le2 x626 only detects charging by USB when in fact its connected to the AC adapter.
And extremly slow charging from 9 to 100 % more then รณ hours.
Also the phone`s microphone is nog working at all!! And the headphone is nog working!
please help
