new original battery

joj3k

Hi umi users.
My original battery was swollen, as most probably of you i think ;)
Guys from Banggood told me that they do not have battery, so I ordered replacement from aliexpress (Store: Powertech Co. Ltd.) 2 weeks ago, and today I received message:
"This batch SUPER battery have quality problem, we can not ship for you."


Anyway, main question is any one know where we can buy brand new and original battery for UMI SUPER??

\n\nI was have the same problem with swollen battery and i bought one from aliexpress.

I replaced it and phone worked again but it doesn't charge.

I dont know if the problem is on motherboard of phone or the charging circuit.

I have measure with multimeter the connector of battery and i see only 0.3 volts.

I bought from ebay here a new USB Charging Port Flex Cable and i am hopping that replacing that i will have charging problem fixed.

Hmmm services manual.
There is no details or informations how to fix phone so any manual will not help you.
I would dissemble phone again and heck all connections. With 0,3V you will not get any charging. Minimum charging voltage is 5V.
Are you getting indication that charger is plugged in to phone?

I have replaced today charging-usb board but problem not solved.
I don't get indication that phone is charging and voltage that i have in motherboard is again 0.3V.

So the problem is on motherboard and without service manual I am unable to repair it.

Is not easier try other charger with USB cable?
Open phone disconnect battery and reconnect again. Then connect charger for few hours.
If still not charge please flash phone with SPFT
Here is SPFT instruction

I tried alternative charger and cables. One of them is from my wife UMI Plus E.
I have disconnected battery and i have connected again.
I have flashed phone.

But problem not solved.

Probably charging IC is damaged but without service manual i am blind.
