(TECH) Battery drains very quickly in Mass Storage Mode.

I own a RePhone Kit Create, I’m facing a problem that the battery drains very quickly in Mass Storage Mode.

After the battery is fully charged, connecting my Rephone to a computer via a USB cable without power on the RePhone, Mass Storage is working. Within a minute, I disconnected my RePhone from the computer and then power on it, very surprised that the battery icon on the screen indicated there is low battery, RePhone is then shut down automatically.

Do you have a multimeter? Can you measure the voltage of the battery? just measure the pin 3 and pin 6 of gsm+ble board

I seems OK after soldering.
