UMI Touch not starting up

mattema

I had 3 days not charging the phone. Now I tried to startup the phone but nothing happens.
No charging, not possible to startup the phone.
Please help.

If the battery is seriously discharged (its voltage has dropped lower than a certain level), its built-in protective electronics turns off its output to protect the battery against complete discharging, that would kill it. In this case the electronics of the phone simply can't detect the installed battery, so that won't start to charge it, just sends short time and low voltage test power signals.
So, if you let your phone to completely discharge its battery, then you left it without charging for three days, then you just used your device improperly.
Now you should keep your phone on charger for up to 24 hours (if needed) to let the battery become alive again by the test power signals. If that doesn't help, then the battery must be removed and charged with an external battery charger.

Hi,

If you already tried not only another charger but another USB cable as well but you're still unsuccessful, then your phone must get disassembled to remove the battery for charging with an external charger device. That should be processed by a skilled repairman.
UMI has released a tear-down video about the Touch, that may help.

I'd just add a note to it: Never use a utility (or any kind of) knife to disassemble your phone since that can damage it. Specific disassembly tools (made of plastic) are available for almost free.
