Battery charging and connection problem, any ideas?

Hello,
I have strange problem, since today I cannot charge my HD while its being on, when I plug in usb charger nothing happens, i tried charging through PC usb port, and nothing happens.
I cannot even establish connection with a pc, don't get 3 choice menu (active sync, hdd, and nothing) on HD when usb is plugged in.
I suspected that the usb port is defected, but when the unit is switched off, it's charging even though there is no amber led on.
It has original rom and radio in it...
Did anybody had similar problem? The phone is under warranty, should I send it for repair?
Thanks in advance.

Very weird. I would definately advise you to send it in for repair. I haven't heard of anything like this before :O.
Good luck!

Hi, I got the exactly same issue as you described today. Have you got it fixed?
Looking forward to your response.
Thanks,

This has already been discussed:
Battery Not Charging
1.Hard Reset after backing up data.
2.Check if SPL/ROM mismatch - if U flashed a custom ROM or SPL.
3.Short circuiting pins in battery compartment of HD after disconnecting of power/USB and removing battery. (Don't short the battery - it may explode).
Try the solutions, if it doesn't work then go for warranty.
Too many ppl seem to have this problem and no one uses search

I did search it before and got 8-9 pages of results. I tried all the approaches but none could fix it. This guy described the exactly the same symptom I have so I really wanted to know how he ended up doing with the issue before I sent it off for warranty.
The problem right now is really on the USB connection, even in the boot loader mode, it couldn't recognize the USB but it could do it just one day before.
Thanks for your reply. I appreciate if you could have some new ideas for me to try.

Have you tried updating your USB drivers?

Have you tried different usb cables?
Some of my usb cables no longer works. I believe my mini usb connector have become slightly looser and I have experienced a cable will charge the phone but won't come up with any options.
Wotth a shot.

The USB driver seems ok since I used the USB connection to flash ROMs and SPLs the day before without any problem.
As for the cables, I tried 5 or 6 total including the stock one but it didn't help.
As stated before, the only time the phone is charging is when I turn it off completely and it charges fairly quickly. However, the bottom (close to the USB end) part of the phone is very hot during the charge. If I turn it on or put it in standby mode, there is no charge or ActiveSync activity.

I have a similar problem.. My phone charges when I plug it in. But I am not presented with any options and ActiveSync doesn´t recognise the device..

same problem here
I am in the same situation. I flashed back the stock ROM, but with no USB, I am unable to put 6.5 back on....any advice is appreciated.

I sent the bad phone (Telstra T8285) back to the seller (an AUS ebayer) and he nicely sent me back a new phone but the story didn't end here. The second phone worked for one day until I plugged in my usb universal car charger. Damn, the exactly same problem happened again at the very moment I pushed in the usb connector. Now I know what the issue has been. I frankly told the seller what happened and he told me what their repair guy found about my first phone, that the fault was from reverse polarity of power supply. I was very surprised because I have been using the same car charger for my previous 3 PDA phones w/o any issues and it's still working for those devices. What's special about the Touch HD?! Does USB have different polarity specs?
Anyhow the seller said he can replace it again but I need to pay the return shipping this time.
What is baffling me is that the phone can still charge when it's off completely but can't when it's on. Does it look like hardware or software problem? Also the USB can't be recognized in the bootloader mode but it could before being faulted by the charger. Does anyone have experience on faulted connector and is there a fix besides replacing the entire motherboard?
Your help and suggestion is much appreciated. Thanks!

The Advanced config Utility has an option for "USB Charging" maybe you could install it and see if the option says yes?

also me... now i figured out what the real problem
i used my old miniusb car charger about one full day before and the same problem start with me with slight different which is charge if i keep it plug in long time...(start charging after 5 min.)
i'm really lucky by not completly dameged
this issued must be listed and get real answer from HTC compeny if the mini usb for hd is different

[Q] Galaxy S4 won't charge

I should clarify the title by saying that trying to charge this phone is resulting in a number of odd results.
So firstly, I've tried using the wall-mounted AC charger. I then tried using USB on my computer, in 3 different usb ports. The phone was charging perfectly less than 24 hours before this problem began.
I plugged it in as per usual, and it didn't show the little lightning bolt on the batter icon like it should. It wasn't registering that it was plugged in. I tried plugging it into my PC, and it wasn't showing that it was connected via USB. In addition to that, my computer was failing to install the drivers for it. I went back to the AC charger, and tried a few different outlets, including one on a power strip. Nothing worked.
I searched online, and found that other people had this problem, and could only fix it by resetting to factory default settings. One person even had to do it twice to get it to work. So I did this, and it still didn't work. I tried charging my old phone with this Ac charger and cable, and it wouldn't work either. So I thought it must be a fault in the cable. So I dug up the cable (also micro-usb) for my old phone, and tried it. It worked just fine for my old phone, but my S4 still had the same problem, but with something new. It would say "Dock connected" but still not charge.
As of right now, it seems to be charging properly with my new AC mount and old usb cable, but I'm worried that this could happen again. Considering this seems to be a problem for other people too, what should I do about it? Is there some way to prevent this sort of thing from happening? Was it purely the other cable, given the fact that it didn't work with my old phone either? I'm on an extremely tight budget, and this phone is my only way of being contacted for job interviews, so having it in working order is very important. Any advice would be very appreciated!

Having exactly the same problem... couldn't find over the internet a solution yet or a position about it...
Affraid it's a hardware issue and have to send to the assistance...
Anyone know what to do?

Yup having the same issues - but i noticed only having charging issues when battery reaches 20% or the low battery notification pops up
it detects that a usb is connected but it wont charge
Solutions:
- dont let it go below 20 which is ****
- some people claim that if you use a 5pin charger instead of the 4pin which samsung includes solves the prob

Mine is a little more serious I think... haven't found a solution like that yet.
I have to connect/disconnect multiple times and it suddenly works.
But between those connects/disconnects it presents multiple problems, it appears on notification bar "Dock Connected", sometimes appears "Dock Connected" and on the notification bar appears "Suggested Apps (Anchoring)", other times it appears "Dock Connected" and the volume bar appears on the screen and stay there freeze (the phone works, but the bar doesn't disappear)... Sometimes the phone starts charging and suddenly stops, other times it says it's charging and if I remove the charger it keeps the charging symbol on the battery icon...
It's completely crazy, gonna take to service I guess.

Have you tried blowing out the usb connector on the phone with a can of compressed air?
If there is a minute piece of dust there it may be shorting something out - error that dock is connected. I know this happens to other phones, there was a big thread about it on the S3 forum. Might be a simple little thing like that...

Unfortunately that doesn't work for me, will send to service, let's see.

have you solved this problem and how?????

Yep, chalk up one more with the same problem!
At first I thought it had something to do with Aviate, a custom launcher from Yahoo (actually a pretty sweet one at that!)
But I guess not.
My work-around is to reboot the phone while connected. It charges fine while turned off and seems to keep charging when booting while plugged in.
Still... this is a stupid work-around and I want this fixed properly.
Any news from any of you guys?

Had this problem today. Suddenly out of nowhere "Dock is connected" message appeared after plugging the charger in and out. Tried to clean out the dock with stick and cotton on the edge. Then turned off and plugged in charger. Problem exists. Phone charges but stops regularly. It is very annoying when you dont know how to fix this kind of problem.
Any new solutions?

Right after this post, I froze the app "battery doctor 4.9.2" using Titanium Backup Pro (you can just uninstall it i guess). Then just plugged charger and now it's already Almost 90% without any interruption.

Amazing! I've dealing with this problem for weeks and internet didn't give me any good answer, but the whole problem was a baterry monitor apk that for some reason was interfiering with the charger. Thank you so much!

I had this problem too and in my case it was a hardware problem. When i start the charging it kept repeating the start proces of charging with the vibration and the grey battery icon(in case the phone was turned off). The battery icon with the green charging light just didn't showed up. I tried many things but nothing helped. I let the phone keep charging for the whole night but in the morning i saw that it didn't charged anyway!
Then i went to a local phone reparation shop(none official samsung) and they knew immediately recognized the problem and it was the usb/charging connector where you plug it in the phone. They fixed it in 1 hour for a cheap price and from then(i think a few months ago) it charges back perfectly. It seems it's a disease with S4's.

In my previous post I was happy thinking that all this charging problems were solved after uninstalling battery apk. But, in fact, my S4 charges very slowly after that incident. I have tried two other samsung adapters (galaxy s4 mini; grand prime). First one results the same (up to 5 hours charging), the latter was comparably shorter (up to 3 hours), but still slower than it used to be (2 hours normally). So I highly suspected the hardware might be the reason. Thank you for your information, now I will also have the phone checked at some local repair shop. And give feedback of course.

You probably got some water damage in your port. What you need to do is clean it. I used pure alcohol and a toothbrush for that. After that I flashed a custom kernel so I could enable fast charge true usb.
That's the reason your phone is charging slowly, it thinks it's connected true usb. So you need to boost the usb charging. After a few charge cycles I could revert back to my standard kernel and the problem was fixed.

I think ur right Lenny.
Mine S4 got wet last weekend and now i am also getting the " Dock is connected" message when i plug in the charger cable.
I can charge my phone but sometimes while charging i hear the sound go off and on what you hear when unplugging the charger.
I will try your solution and hope it will fix mine too. Thanks for posting ur tip!

I suggest you go buy a new genuine cable for an s4, the s4 does actually require a special cable capable of 2A charge rate otherwise you can end up in all sorts of bother.

Thank you all for sharing tips. I cleaned the port as suggested, then replaced my cable. Now everything is back to normal.

Same problem - galaxy s6
Hi there - same problem, on my 128gb s6. started this morning. Yesterday everything fine, would charge when connected via USB to both laptop and to regular samsung usb power unit. Have now tried 3 different USB cables including the samsung cable, 3 different usb power units and of course tried all 3 cables in laptop usb port. Have checked phone's usb port - clean as a whistle. Have rebooted both connected and unconnected. Started getting 'dock connected' message, now it just wont charge, although starts up fine. I take very good care of the phone, so no water damage or untoward shock damage (never get it wet, never drop it). Remaining battery charge seems to fluctuate between 30% and 40+ %, depending upon whether it's plugged in or not. If I turn it off, then connect usb cable, the phone just reboots, still not charging. I then turn it off and see no green battery charging screen, as I used to seen when connected but turned off. Should I just hard reset and take to repair shop? Still under warranty.

I would return the phone for a warranty repair. Software would not usually prevent the phone from charging when powered off.
As a final test, see if the s6 will charge wirelessly, assuming you have access to a qi charging pad and the s6 has a built-in qi receiver like the North American version of the s6.

[Q] Nexus 4 charging mode won't stay in AC, drops to USB

phone only started doing this over the last couple months, used to be able to plug in (either charger / cable) and charge in AC mode without supervision.
Nowadays, it takes several plug in attempts to even START in AC mode, but typically it'll drop down to USB (the screen comes on momentarily when the change occurs) at some point in the charging.
Worst case scenario, it'll change rapidly back into AC and out, to the point where I can watch it on happen on the screen. That's rarer though.
It never changes INTO AC and stays there, to be clear. Always a downgrade to USB charging.
Is something wrong physically with the jack on the phone? I've never damaged the phone, dropped in water, etc.
If RMA is what's suggested as my only option - is that a brand new phone or refurbished?

Use another USB charger, its a known problem with the supplied LG charger with the N4. I myself have this problem but am using another charger and its fine.
The USB cable has no problems btw, its the charger itself.

Can you link to your sources on this being a "known problem" ?
I'm pretty sure the same issue persists with my old Samsung charger too - the one supplied with the Galaxy Nexus. So.. that suggest the problem is with the phone, not the charger/cable.

i also have the exact same problem just now.. i'll try using another charger tonight at home..
just now i charged my nx4 using its original charger, in just a couple of minutes, the phone is saying that its being charged using usb.. stupid..

I'm also getting this at the moment, I'm completely stock, not even rooted and this has cropped up only since the 1.8mb Security Patch....
Any fixes?
Will root if I can fix it....

I was/am having this issue as well. I typically charge my phone via car charger (works fine) or wireless, so I can get around this issue easily. Plugging it into the PC and enabling fast charge with franco's kernel works as well.
I tried my N10 charger and it was dropping to USB as well. When I'm at my friend's place and use his generic charger, it works fine.

I used to have this issue but ever since I updated Android to 4.3, my charging works just fine.

Might try a factory reset and see does it make any difference...

do we have any more thoughts on this issue? is it a software bug? is it hardware? which hardware? I am going to experiement with a few different wall chargers and usb cables.

so 3 chargers (Galaxy Nexus' , Nexus 4's, USB 3.0 port on PC) and 3 cables (likewise + cable from monoprice)
SEEM to yield the results, that the problem is the connection between the cable and the phone. The oldest and most used cable has the hardest time establishing and maintaining an AC connection, the newest/lest used one from monoprice has never had a problem, and the LG cable is in the middle.
Is this an issue of wear and tear on both the cable connectors and the phone's port? It's really lame the phone and it's cable are not even a year old and THAT can't stay charging at AC voltages.
Will a replacement phone from Google be a refurbished unit or brand new?

They will send you a new (not refurb) phone and you will have 21 days to send back your old phone. The replacement process is super easy, just call them at +1 855 83NEXUS and tell them your issue. They will walk you through a factory reset and if the problem is not fixed they will replace it.

I've had issues with the microusb port on multiple phones in the past, and have definitely noticed the N4's socket getting looser.
On an old HTC sensation, I had to resolder the port on. Can you reproduce the behavior by applying slight pressure to the plug in various directions?
Does your connection also intermittently drop out when connected to a computer?
A workaround for the time being could be to use a kernel that allows you to force fast charging regardless of the detected charger. But at that rate, it's quite possible you'll lose your usb port altogether sometime in the future..
You could also enable adb over wireless, and check the charger type:
Code:
cat /sys/kernel/debug/msm_otg/chg_type
You should be seeing DCP (has the data pins connected, possibly with some resistance).
Or proprietary if you're using an Apple-compatible charger (has aspecific voltage on the data pins).
If you see SDP, it means it's in "USB" mode.
If it's staying DCP/proprietary but the charge rate is dropping to "USB," it means the phone is throttling down the current because it's detecting the charger can't deliver (voltage dropping below threshold).

with the good cable (monoprice), wiggling has no effect.
with the poorest cable (samsung), wiggling will rapidly change it between AC / USB / nadda
with the LG cable, wiggling, will SOMETIMES have an effect. sometimes it's solid and will only become a flaky connection after it's been charging a while already

Dead YD206

So YD206 about a month old. Was connected to official yota charger (via a magnetic usb cable), noticed the plug at the phone end getting quite hot. Phone now essentially dead, wont boot, doesn't seem to charge. We also realised the charger had come out of the wall socket. But the yotaphone light was intermittently flashing on the charger.
Whilst I am inclined to blame the magnetic charging cable, is it possible for current to flow in reverse from phone to charger and essentially discharge the phone battery below acceptable levels?
Any advice on rebooting it (can't remove the battery like I would on a Samsung) so whats the procedure?

Just a follow up charger not the issue, it crashed in use and the power button became non-responsive, with the screen off, and the e-ink display on but also unresponsive. Did not turn on when connected to a charger. However when I connected it to my pc it did register in device manager as MTP device, so I knew it was still alive. Removed the sim and held the power button down for 10 seconds then it rebooted.
Hope this helps anyone else with a similar problem.
Failing that it would probably have to be left to discharge (might take a while if nothing is running) then powered back on with charger attached.

I have similar problem. My phone got hot while not charging (about 15% of battery) and crashed. Then forced reboot (hold power button for about 10 seconds) helped while phone was connected to Yota charger, battery was dead, but phone booted (EPD on, did not check rest) and got to about 81%. After removing it from charger, same thing happened again, no luck with forced reboot this time. Phone was blazing hot and did not respond, then crashed again. No response after connecting charger or forced reboot. Any experience with this issue appreciated.

It seems a battery issue. Have your Yotaphone a valid warranty?

I am not sure about my warranty, bought it off AliExpress, I guess I could try to send it to manufacurer (i heard Russia provides repair service).
EDIT ( t + 2 days): I managed to start my Yota again. I connected it to computer and after about 5 minutes, magic happened and phone started all by itself. I will try to find out more, will update this as soon as I find something

Man, you are more lucky than me, I have a dead yotaphone lying around here. It also died after connecting it to a bad power source.
In my case it was the usb-port of a monitor.
When I checked the usb-port with a cable with a volt/amp display I saw that it was going on and off very quickly.
But so I would say be careful where you connect your yotaphone to, it does not seem to handle weird power sources all too well.

I actually thought about burning charging circuitry a lot. I wonder, if you would be able to test wireless charging. With some luck, it is independent enough to not be affected by burning micro usb charging route (depends where high voltage safety is implemented). If this make any sense to you, please give this a try (I think IKEA is place to go, they should have working wireless chargers in their model setups) and report back. If I am wrong in any aspect, I'd appreciate any correction with explanation.

Sorry for the late reply, did not see the quote, but it does not work with wireless charging either. I think the battery still has a lot of charge too. Thing is that the Motherboard also gets hot after a while when I try to charge it. I'm pretty sure my motherboard is dead. But I have another Yotaphone now, so maybe in the future I will test with every separable part replaced.

I use the charger from my iphone. It works great, although with the yotacharger also works well. Attention that I have a YotaPhone YD201 with Russian base and european compilation. Like I said the Iphone charger works great and doesn't warm my Yotaphone 2 . It might be a solution for your problems with charging.

Problem recognizing charging, headset, and PC connection

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.
