Help on Charger plug (z2 pro) - Lenovo Zuk Z2 Pro Questions & Answers

Did anyone have this as well? Mostly I charge my phone when it's almost, but not completely, empty. Nothing weird going on. Last night it shut down because the battery was dead. I had put it on the charger and saw that charging had been initiated.
This morning the battery was still dead. As there is no simple way of switching to another battery I got a bit nervous. I their charging it with a couple of chargers, including one of our Samsung tablet (because that one might do 2amp)
Nothing seemed to work until I got to my work and tried again on the charger of my Logitech mouse. Then it started at slow charging, but hey better then no charging at all. I noticed the plug does not go in the slot all the way... Is that normal? I tried 2 USB c connectors and both have this. I have looked into the charger socket but I don't see anything that could block the plug.

tilt totally dead, cannot recharge, cannot turn on, help.

hi, new member here.
bought my tilt on 10/4/07. has been flawless since that time.
used the nav quite a bit during a road trip, used a cig lighter usb charger.
got home and my battery was at roughly 40%.
put it on the charger at night went to sleep. in morning disconnected it at 8 am. shortly after i arrived at work i got the critical battery low chime. checked and it had like 7% battery life.
figured i didnt plug it in right, or it got knocked loose some how and didnt get charged.
put it in flight mode to minimize battery usage. left work at 2 30 pm (4% battery life) and put it on the car charger. got home and put it on the HTC supplied wall charger. light turned amber, so i assumed it was charging.
checked an hour later and turned phone on, it said 0%, and immediately died. left it on the charger for a few hours and the light was still amber, turned it back on and again 0% and phone immediately died and did a soft reset on its own. i turned the phone off and left it on the ac charger, took out the sim card and put it in an old blackberry to use while the battery was charging.
its been on the ac wall charger for the last several hours, i checked and the phone is totally dead, cannot turn it on, and the LED at the top is now RED.
what is the problem here? why wont this thing charge?
thanks in advance, i have alot of critical info on this device and any help would be greatly appreciated.
i cannot hard reset because i cannot turn the flippign thing on....
Does it charge when you connect it to your computer? If it does, then your charger is toast. If not, then it's probably the phone itself.
I'd try a different charger first. If that makes no difference then a different battery. If that still does not make any difference then time to exchange it.

connected to either the computer or the wall charger, the LED thats normally amber when charging, and green when charged, remains red.
I had something very similar happen to my wizard.
And as weird as it sounds, the only fix was to charge the battery in a friends wizard on his charger. I'd check the battery if possible.
Could be the battery. Know any place or anyone that will let you try a charged battery? If not, you might have to go in to an AT&T store.
i think i got it working. did some reading/browsing...
took a usb wire and cut the mini usb head off. dissected it and found the the red and black charging wires. took out the battery and held the leads to teh battery while the other end was plugged into a USB/AC adapter wall charger from a old blackberry. after manually charging the battery for several minutes, i put the battery back in the phone and the phone started up. now it seems to be charging off the wall charger and the led is now amber from red.
thanks for all your help/suggestions.
well it worked briefly. the amber light has gone back to red and it seems that the battery is not charging.
dont know what happened to my perfectly functioning phone.

Repeat this proceedure but this time do not turn the phone on, just plug it in to the wall charger once you have zapped the battery again.
Turning your phone on probably just caused the already recovering battery to die whiles it is trying to take on a charge.
It is mentioned quite a lot on the boards that Li-Ion Batteries do not like being over disscharged and there is usually a little protection circuit in the battery to provent complete disscharging although this circuit may be on board the phone. Completely disscharging a Li-Ion cell will kill it stone dead and it will need replacing.
When you took the battery out and so called jump started it with your flying leads, this possibly reset the little protection circuit in the battery so it can now take on a charge. I feel that once you turned on the phone, this was to much for the already depleted cell to take and possibly re-tripped its inbuilt circuit.
If you do manage to recover you cell, in future it is good practice not to let the battery go below about 25%. Li-ion cells are generally happy being top off regularly.
I hope this helps buddy
Do let us know!
Cheers

thanks, that was very helpful.
ive tried defibrillating this battery out of the dead several more times to no avail.
ill try it one more time when i get home from work, if its a no go i will go to teh att core store. the phone is 6 weeks old, dont know what they can do for me if the battery is toast...
That Sucks! I hope they'll give you a new battery.

I had exactly the same problem with my battery. It came on though after a day. Although the battery life after this happened went down to 10hrs max on standby. I sent the phone back and got a new one and now all is fine.
This is a problem that affects almost all makes of phone. There are three (main) causes of the problem:
1.
The battery charge drops too low to allow the charging circuit to recognise a battery is even in place (red no charge light stays lit)
possible solution:
http://forum.xda-developers.com/show...22&postcount=6
(in the end very similar in the end to the USB wire used in post above)
2.
A faulty battery (but if you can charge it using a cut usb cable or using a couple of AA batteries this may not be a faulty battery.
3.
A faulty charger OR a charger not delivering 5v at 1000mA as the OEM one does. Many chargers that are used for other phones or generic chargers only deliver 500mA. This is not enough when your battery drops very low. (these chargers are OK for occasional use but I do not advise using them regularly particularly if the no-charge syndrome has shown itself)
4.
A faulty USB connection on the phone. I have now seen a couple of reports where the fine wire connections in the phones USB port have become bent out of place.
Number 4 above is at least possible for the OP as it seems the battery will charge using a cut USB cable but not when either the PC USB cable or mains charger is connected. A USB port on the phone with a a bent internal contact would explain what's happening.
A previous poster was able with a needle or similar to bend the contact back into place.

i had the same problem with my phone.
put it in the charger overnight and woke up in the morning and couldnt turn on the phone with blinking red light. I don't know if my battery was over-drained though. I went to AT&T and was playing around with their charger and new battery and somehow the so-called dead battery started working again. They changed the SIM card on my phone there and then i haven't been able to use the phone since. I've changed the network to GSM instead of Auto setting under Phone Options which allows us to make calls; but now I can't connect to 3G network.
Charging thru mini usb
My phone started to exhibit similar problems...plugged in but no charging of the battery. I finally realized that my mini usb connection on the phone has been compromised (bent, distorted=not functioning properly) Now I have to prop the mini usb connection up at a slight angle to engage the charge. I think the plastic/metallic connector on the phone is somewhat fragile ...I had similar issues with my hermes.
called customer support.
they are sending me a new phone and battery.
how do i know its not a refurbished one? any clues?
before u send out your defect phone, have u check if your phone's mini-USB connector has bent or misaligned pins?
yeah all the connectors visually are fine.

Not charging stellar

Hi.
My xda stellar is not charging but in a very strange way...
The orange led is glowing and in power menu i get the "charging" notification but in fact the device is not charging... :S What's wrong??
I think that it happened after i tried to charge the device using a motorola charger. I don't have the original charger i used to charge it with an htc mini usb charger that i had.
The pins of the usb port seem ok...
For the moment i'm charging the battery outside of the device.. :/
Any suggestion?
Could be an old dried used up battery.
I tried a second one(new) that's not working too.....The device was working perfectly until i tried the motorola charger..
Hey, I'm having the same problem and I seeing as i brought the phone second hand it didn't come with an official charger and just used the USB mini i have laying around. Again I have replaced the battery thinking it was that. Nada. Still doing it.
I've taken the phone apart and cannot see anything wrong.
So I was wondering until the problem is solved, how are you charging the battery externally?
Thanks

[Q] Charging Problem

So... Yesterday my battery decided to drain really fast. Checked the mA and it was -1137 and when I plug in my charger it decreases still to-500 or more than -2000. When im not using my phone the phone will charge about 5% per hour and stops charging at times. Leave it over noght and it might charge 10%. Same gies for when the phone is turned off and charging. So, is it the usb port or the battery.
The battery drains real fast. The port is clean and the board looks fine when i dissassemble. Usb cable holds tight, when i pull the connector part up then it disconnects.Used multipll cables, sockets, and chargers.
Is it my battery or the port?

I've just posted my solutions to some very similar problems you've described. Not able to to post links but it should be easy to find, just search for [solution]usb port / charging issues.
Have you checked the two copper plates on the under side of the removable plastic unit just above the usb socket. Adjust / manipulating the connection there has solved my charging problems.
Hope this helps. I'm not an expert by a long shot, but if this is not the case, and you have replaced / renewed everything, then I at very least would recommend trying a new battery.

Sometimes won't charge if plugged in

I've had my N6 for about two weeks now, and lately I've noticed it doesnt charge once I plug it in, I'll go to sleep and a few hours later its still at the same percentage, I check the battery stats page and it shows "Not Charging" I unplug it for a few seconds and the Charging icon sticks as like the phone thinks its still "charging". Another issue I've noticed just now today, it says itll take 4 hours to charge from 56%! Only way for me to fix these issues it is to restart the phone and itll work, mind you this issue only happens sometimes. Although I will say I plugged my LG G2 into the Turbo Charger, so IDK if that affects the charger in any way?
Does anyone else experience this? If this is something no one has I'm planning to swap the device out for another one.
Running SinLess ROM v1.0.3
what charger are you using for your n6? and where are you plugging into? wall or usb?

This may seem obvious but try a different cable. I had a cable that, when plugged in, my phone would say is charging but doesn't actually charge.
I've had my nexus 6 for a couple weeks now and the first time this happened I was using a wireless charge so I thought I didn't have it placed on the mat right. But it happened again last night whilst plugged into an AC charger. The AC charger is an LG charger from a previous Nexus. When I look at the battery graph it just flat lines for the whole time it was plugged in.

My turbo charger is doing the same thing the OP said. We have 2 6's and it also happened to my wife's the other day too. I thought it might have initially been a cable too so I changed that out and it happened to the second charging cable last night as well.
Just experienced this
I use the turbo charger also and just experienced this. I was at 25 % after playing injustice (which just murders this battery) and plugged in the USB and I looked back 5 minutes later at I was at 22 %. So I killed Injustice and waited about 5 minutes more and I was at 19%. I had to reboot to get charging and after 5 minutes of charging I was at 29% so it is weird stuff.
I've been noticing this as well, but my charger is an aftermarket charger by Tenergy (Amazon link), and I'm using an aftermarket cable. Missed my alarm this morning because the phone must have not actually been charging, even though the N6 always shows that it is charging. I haven't tested it thoroughly with the stock charger as I keep that next to my workstation, but it seems that others are having this issue even with the included charger. Frustrating, to say the least.
Same thing with my N6 on 5.1. I would say that 20% of the time i plug in it shows charging but doesn't charge, just maintains the battery at whatever percentage it was when i plugged it in.
I don't have to restart but rather just unplug and re plug in the charger, then monitor for a couple of minutes to make sure the battery is going up and if so it will charge normally.
I also have tried a few different chargers including the quick charger that came with the phone. same result.
the same. here

Wow, same here.... only just started to notice it. Using turbo charger as well...however upon using a normal charger, it seems to always charge. it it something with the turbo charger?
Yea it seems to be turbo charger problem , but how come I bought it just one month ago !!
I started noticing the same issue recently. I'd say it started after upgrading to 5.1. I'm using the stock turbo charger. I found a workaround that, so far, fixes it for me (3 nights in a row at least).
After plugging in the phone, I notice the battery icon shows it is charging. If I actually go into the battery settings though, it says it is NOT charging. If I unplug the charging cable and plug it back in while still in the battery settings page (you know, with the usage graph), then it starts charging just fine up until I get a full charge. As long as I do this each time, I seem to get a full charge. Annoying, yes. But not as annoying as waking up to à phone that never charged.
Sometimes it won't charge when it's not plugged in either
For my N6 to charge, I need to push the TC USB cable a little downwards for my phone to charge. Sometimes, it doesn't even charge at all. I'm considering to RMA this, if I can do it here in Norway.
my nexus 6 has different behaviours, if I charge it when it is turned on sometimes it stops the charging and I need to disconnect and reconnect the cable and charging starts again, so i need to be careful because i can't be sure that my phone will charge completely if i leave it alone. if I charge it when it is turned off sometimes it starts to restart continuously showing battery in the screen again and again, without charging. hopefully this happens sometimes, i dont really like this bug, i spent so much money for buying it and i dont want to control if my phone is charging or not when I plugged it, i just want to put in charging and coming bac when it is flly charged.
RMA it
I hope the first thing anybody does is check the charging port and make sure there's nothing in there. Take a strong, sharp toothpick and carefully dig anything out that shouldn't be there. Pocket fuzz etc...
I am having this same issue, my phone is brand new yesterday, running 5.0, I have these exact issues, seems to be only with the turbo charger because I use a slow charger for overnight next to my bed and the battery was full. But I can't seem to make the percentage actually go up with the turbo charger without restarting the phone first.
Any more info on this very annoying bug??
can't seem to figure it out
i have the same issue - my N6 is a couple of months old and it started on an overnight (not) charge. Now it's happening 1 in 2 charges so it's getting worse. I cleaned the connection, tried different cables, USB chargers and plugging into the laptop - no dice. It's going back to Google - annoying...

Charging/Battery Problem, Possibly Hardware

I have an S3 I9305 with CM11 and a ZeroLemon 7200 battery. Have had no issues until last night, after years of use.
I have more than a few chargers, one of them always goes slowly. It's good for overnight charging and usually I can get more than a day out of a charge with this big charger.
Last night, though, I put it on to charge and after a little while I noticed that it was scorching hot. My battery monitor app read 131F. The charge percentage had gone down although it had been plugged in for a while.
When it had cooled, I tried plugged it in to a different charger and it failed to register that it was plugged in. The same is true for every charger I've tried. The only one that shows up in the OS is the one that caused the problem, and it immediately gets hot.
I have cleaned lint from the port and tried a stock battery. The issue remains. Also worth noting that when I plugged into a PC, it registers for five seconds and then behaves a though nothing is plugged in.
Finally, if I plug in the only charger that registers, with the phone powered off, it seems not to actually charge.
I've scoured these forums and I've found similar issues but none that seem quite like mine.
Is it a hardware problem? I recall that the phone took a bit of a fall yesterday.
