Doing Hard Reset aka Factory Reset on Sony Xperia go ST27i / ST27a and Charge the battery.
If you owned this 3.5 inches phone for the first time and you wanna turn the phone on (by pressing the power button until it vibrates) for the first time after you had been assembled all the part (SIM, microSD memory, and else), you need to charge for at least 30 minutes the battery of this Xperia go. FYI, the battery is unremovable and replaceable type. This must be one of the reason to acquire the IP67 certificate. That is why there is no tutorial on removing and assembling the battery for this device. It uses Li-ion type with 1305 mAh capacity.

To charge the phone all you need to do is connecting the microUSB port with your phone. The USB port for charge had a cover that you need to open first. Use your finger nail to open it. On the other end of USB plug the USB port into Power Adapter then finally plug the Adapter into Power Electricity Source in your Home. Done. Otherwise, you can directly connect the USB cable into Personal Computer. Though, we not recommend this charging option if it purposely for the first time of battery charging. It may take a little longer than via Power Adapter.
To do Factory Reset aka Hard Reset all you had to do just Go to Settings > Tab Privacy > Tap Factory data reset > Reset phone > Erase everything. But, in case you just wanna reboot / restart the phone, you can follow this key hardware combination: Press and Hold the Volume button and Power button at the same time, then release it whenever the phone vibrate. This action sometime also called as Soft Reset.
In case you phone stop responding or touchscreen is frozen, you can turn off the phone by Holding and pressing the Power button for about 11 seconds, then wait until the phone vibrates 3 (three) times, and release the key. That would shut down the phone automatically: forced shutdown. If the freezing problem frequently occurred, you can do Factory Reset, but make sure all you data got saved first (back up needed).
