Help! iPhone won't start suddenly

[2ndfunction]

Here to ask for help and roughly what happened to my phone ...
Basically I just changed my iphone battery around 1.5 month ago. So one fine morning, I woke up and used my phone before heading to the showers to wash up. After returning, the phone suddenly went on restarting mode. (The apple logo lights up and after 10 secs dims down. Continues on a loop.) at first I didn't bother about it and let it run. So after around an hour or so the phone worked back to normal.

2 days later the same thing occurred, just that this time round the phone just died totally. Battery percentage was full. My iphone lock button is spoilt so only was to turn it on was to plug into a power plug, but couldn't be started even plugging into the power plug.

What could be the reason? Didn't have such problems before changing the battery.
