Hello,
Two weeks ago I bought a wonderful tablet Lenovo Yoga 2 pro.
Amazing tablet, and the built-in projector is just a bonus in addition to his other great features.
The tablet comes with a powerful battery and a quick charger.
But, after only a week since I bought it suddenly it stopped charging quickly as normal.
and now even with the original charger it charged only 1-2% per hour. It also does not display the battery charging icon above.
And another thing, Connecting a data cable / OTG also does not work (this is the same socket connection).
It happened after a night it was connected to a charger. And and a day after I was connecting a dok OTG.
What do you think it could be ... I am desperate for help
I think it could be two directions of issues, or programmed settings of the USB socket somehow got stuck in the mode that takes power.
Or otherwise that the socket is screwed hardwarely.
(I'm not giving it back to Lenovo's responsibility since I bought it in the United States on a trip and now I have returned to Israel ...
Thanks to all who help.
Hi , I have exactly the same problem after I connected to an OTG a micro-usb pendrive for a while , except that when charging it displays the charging icon but as you mentioned it charges 1% /hour but if the tab is off it does not charge at all
Did you find since then the solution to that problem?! my email : [email protected] thank you and I appreciate your help!☺
I had the same problem and I had to send it back to Lenovo for warranty, they replaced the motherboard and battery as part of the repairs.
I tried everything to fix it myself outside of cracking the device apart beforehand with no results.
When I had the issue, I couldn't sync the tablet to my PC either.
After it was returned, no issues.
Also same problem above so slow charging then if the tablet is off it is not charging at all plz help me thabks

I don't know about you guys, but charging my P7000 is a struggle. Literally, it takes on average 6 hours to charge from 0 to 100% with the stock charger. I tried many different chargers (Samsung 2.0A, Aukey Quick Charger, Asus VivoTab 8 Charger) and they are all amazingly slow (usually even slower than the stock one).
Could anyone figure out how to charge this phone faster? It drives me crazy to take this long to charge!!!
Thank you.

Hi there!
Your problem is not a weird one my friend! I have 2 chargers: the telephone one (which sucks, unfortunately) and a huawei ascend's.
At first my elephone charger worked fine and charged my phone in 3 hours. Same with the huawei.
My telephone charger though sucks because it broke after little use (mine lasted 2 months, my gf's only 1 day and a friend's less than a month and I doubt we are the only ones with that problem).
Please try a few things to determine where you stand here:
1) charge it with another USB cable (successfully tested on another telephone)
2) charge it on a successfully tested plug.
3) if you're using an adapter, try another adapter.
If nothing there changes your battery charging time consider testing your hardware pasting this code on your phone: *#*#33#*#*
Try the charging setting and if it gives you trouble send it back for another device
I can testify the phone charges in 3 hours with the telephone or huawei ascend charger when they all work fine, but the elphone chargers and USB cables are aweful, they brake easily and the USB port on the charger loosens very quickly which doubles or triples your charging time.
In a beautiful day, when I forget my charger at school, I used my PC to charge my cellphone ( just 2 days like that) and the cellphone was detecting like usual: If connected to pc it shows charging over USB, If connected to AC it shows AC. Ok then, so What is the problem? After One week, when I was travelling using the phone as usual the battey ended and cellphone turned off at 0% (perfectly normal), as soon as I was travelling I used car charger to charge my Zenfone (It is an 2A car adapter). When I connected the cellphone (I was on Stock ROM) it take more time to detect charger than usually (like when you connect it the phone instantly shows the battery icon when off) it takes over 20s connected to charger to show the battery logo, the phone was saying that 1/4 of battery has been charged (WTF it was totally discharged from 100% to 0% and when I put 20s it charge that much? This is not possible I tought). When I turn the phone on it was showing 30% OF BATTERY, I wondered how that could happen. (I alreay saw this bug on my friend's cellphones from other brands like Samsung & Motorola). Anyway, when I saw those 30% I saw the battery graph (wich shows if is on AC or USB) and it was showing charging over USB. BUT HOW THAT COULD BE USB, ITS A FRRAKING 2A CHARGER WTF ZENFONE. I tested on my sister's phone with same cable and same charger, it was showing charging over AC as well. When I finally get home I let it charging, after 1h30m it just charged 15% with Asus AC charger & at the battery graph still showing charging over USB, when I tried to connect it to computer the phone was showing charging over USB (btw it was ok because it was on PC) but windows doesn't said nothing was connected, no USB mismatch, NOTHING. I was on panic. WTF HAPPENED TO MY CELLPHONE. This day I decided to go to Marshmallow, soon as I have root and TWRP pre-installed (when I still have usb connection {3 months ago when I made root}) So I downloade RR zips, upgraded, everythig was ok, Marshmallow Running successfully. But one thing wasn't ok, the freaking charger detect. It was still saying "over USB" but it was on AC. Tried to go o bootloader, no answers from the phone either from windows. I bought an USB-OTG adapter, not working too. I bought an new microusb sub board, replaced it to the new one. No success, still saying charging over USB, no pc connection. Just one thing chaned: OTG before SubBoard change it doesn't even gave energy to "feed" the pen drive, mouse doesn't work too. This night was when I became freaking mad, I let it charging, when I turn the phone on it has just 25%. 6h Charging and 25%. I said to myself, this couldn't be possible, no way dude. I don't know what to do anymore, I'm desperate, is the only android phone that I have, already tried many chargers, many cables, many different computers, no clue of what happened with this cellphone. So is not an hardware issue (as soon I already had this issue, but it get back to normal by itself last time, I didn't do anything) but now it has been 1 month charging "over USB with short battery life. What am I suposed to do now? I tried repair battery life PRO, app from an XDA member. It says everything OK with battery, screenshot below: (translate: No problems founded). And another screnshot of the USB problem. As you guys can see my battery graph is sh*tty, never get to 100% in one day because of this issue.
@gadmei.tw @TecnoTailsPlays (New thread that I was saying).
Please anyone help me, I don't know what to do anymore . I always helped guys with other issues on RR and other rom's issues, now please I need you guys to help me.
Sorry for my bad english, I'm from Brazil and I'm nervous now.
Thanks XDA :crying:
I half read your story .I think your battery is miscalibrated.You need root and a app to calibrate it.
Say thanks if it helped.
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.
Hi guys,
I've come across a weird issue with my M3 - out of the blue I can not connect to computer via USB cable(the connection is not recognized by M3 and on the PC side it says the connected device can not be recognized). Another issue is that the fast charging is completely gone and even normal slow charging works only when the pad is powered OFF. When its powered ON and put on charger, nothing happens. So I have to power off, connect to charger, it will start charging and then eventually I can power ON and charging will continue. However the charging is very slow and takes almost 6 hours to charge from 0 to full.
My charger and cable are original Huawei ones and are working properly. I tested another huawei charger+cable and same result - no proper charging and no computer connection via USB. My M3 has locked bootloader and never been rooted. I flashed various firmwares(M and N) but no change, problem persists.
Any idea please?
Thanks in advance, brgds
Tomas
I am having the same problem with my M3. I've tried connecting it to the HiSuite and that isn't connecting either.

I was unable to fix the issue by myself, visited HUAWEI Service Center, they had no idea what is the problem first, then they decided to change the sub-board and returned me the device. Problem was the same so I returned it back to service center, they ordered another sub-board and replaced again, this time everything works fine. Seems like the problem was fixed. BTW my model is US version(wi-fi only) and I am based in SE Asia so I had to pay for the sub-board replacement despite device being under the warranty.
Hello,
I own a Ticwatch Pro for now about 2 years. I don't use it very much. But since I own it, I always had problems to charge it.
If the watch still have between 70% and 90%, then it charges quite well (but very very slow, and I need to power on the watch or it will not charge).
Below 70%, the watch does not charge ... I need then to disconnect / reconnect many times thes charger for the charge to begin.
I cleaned the contacts, and I use a 5V 1A charger.
But now it's even worse : the watch was at 93% of charge, I connected it to the charger. The watch was showing the charging icon. But in fact, it did not charge anything.
Now the watch battery is totally empty, and I cannot charge it (I tried with two different 5V 1A chargers, even with a PC).
Does anyone have a clue on how to solve this issue ?

I have found my problem : the charger is dead. But in fact, the original Ticwatch charger was dead for a long time, only charging the watch after several tries. I ordered a new one on Amazon (not branded), for 7 €, and it works a lot better than the original !!

Hi ! I know it has been a while, but I believe I have the same issue with my watch, I got the Ticwatch pro 5, and just after 2 days of owning, the charger won't work, I tried unplugging and plugging back like they suggested in the FAQ, but that did not work either.
Like you I am suspecting the cable, and went on to order another one now, any chance you got the same one ( SKEIDO USB Charging Cable Power Charger Adapter Dock Magnetic Stand for ticwatch- proX/pro3/pro3 LTE/pro 3 Ultra GPS Smartwatch ) , also, has the issue ever happened again to you ?
Thanks
