Strange problem with ZUK Z2 - Battery? - Lenovo ZUK Z2 (Plus) Questions & Answers

[UPDATE] SOLVED!! I changed the battery for a new one. Works great now! [/UPDATE]
Hi, guys!
My Zuk Z2 Plus have a strange problem.
I can't work on it without energy cable connected. My battery says FULL, with 90-100% of charge, but, if i remove the cable and open an app, it reboot and stay rebooting in logo (until connect the cable).
I tried unlocked bootloader, put another ROM and the problem persisting.
This ZUK Z2 worked well 10 months and now came this problem.
(sorry for my english, i'm brazilian)
Here a video demonstration:

No no, what I was asking, is, if you did unplug you cable when you were in TWRP. Does phone turns off or continues working?

The same thing happens to me, I even thought it was the ROM or something and it turns out that it's the battery, I think

Ohhh.. sorry!
Yes, happens if i try to install a new ROM or uses more "power" from battery.
If the cable is connected, it install normally.

This is bad!
My problem started in some applications and generalized.
Now, anything that consumes more battery power, it restarts, as if it could not supply.
I think I'll try another battery, but it takes more than 30 days to arrive.

So it seems its really battery..
Just as last check, you can get USB voltage tester and look battery amps.

Hi, Galileo.
I testes many chargers and all can charge only at 200mA current.
Here 2 pictures with and without cable connected.

Apps never will told you true about your battery. You need check it with portable usb tester.

Do you have to remove the battery to boot the phone up? Or is it just the battery graphic just shows up as still charging?

Just the battery graphic shows up as still charging. It doesn't seem to be affecting anything at this moment. Just annoying, but I would like to take care of it before it could cause any issues.

Strange dude, you could try a different kernel. I had that issue before but it was when the phone was turned off and charging. The phones used to hang with the charging battery logo and I had to battery pull to turn the phone on again.
Once I switched kernels the problem went away. Hope that helps.

Thanks for the help. I'll try another battery pull and see if that works. I'm waiting on CM9 to ROM.

Change USB cable/Charger your using, change input, use laptop/PC instead of plug or Vice Versa, or it may be the port where you plug it into your phone, if above fails, the port is probably broke, fnd an angle it charges at, and create a method to always have it at that angle..

I know there is a method to reset the battery file but I donĀ“t know where I read that
You have to hold some buttons for 10s while the device is off.
Try that at your own risk:
1. Turn off your Tab
2. Plug it in (wall charger)
3. Wait till it shows a charging battery
4. Press and hold menu-button 10s or more
OR
1. Turn off your Tab
2. Plug it in (wall charger)
3. Wait till it shows a charging battery
4. Press and hold menu-button + power-button 10s or more

[Q] Sony Xperia T2 Ultra Dual Charging Problem

i recently got a T2 Ultra Dual and whenever i try to charge (either with Data Cable or wall charger), it start showing the start up guide and screen brightness goes to full and mobile data, bluetooth and NFC starts automatically but one thing that it doesn't do is charging the phone itself. It keeps doing the same in a loop (which is annoying and battery consuming, which you can't charge). Does any one have any solution to this problem???? please help..:crying::crying:

Well i have had a similar issue with my T2 Ultra....Not exactly the same but when i used to plug the USB in...phone wont charge while its turned on......and when i wud switch it off it wud show me discharging status........What i have figured out in my case were 2 things... Most likely it has to be the USB driver cuz it happened to me twice and both the times my laptop was going through an Update.......after finishing the update and restarting the laptop....everything went smooth. Secondly i googled about this issue and i read somewhere that its cause cuz of the USB pin (inside the USB slot in the phone) bends slightly down so cant connect properly...so i moved it to the center with the help of a flat headed screwdriver. I am not sure it would work for you but its worth giving a shot.

Nah, no luck. Its so hard to get into fastboot and then flashmode. It goes into black screen. Don't know what to do next??? thinking about giving it back to sony and to get another phone, probably not T2 ultra
Haha.. It was just that demo mode was enabled in the phone. I didn't notice that.. Disabled demo mode and now it's working great...
