Once, my phone hang, i will remove the battery and then restart it. Or i will leave the phone alone for it to drain the battery and off itself. Then, i will charge it again and it will be working like new phone.

Alternatively you can take the phone to a special

What if the phone doesn't allow battery to be removed. I got your second option though but the first option doesn't really exist in most new phones.
