Why is my phone not turning on?

Hello, i have a Huwaei Ascend G730 which stopped at midnight while I was using my phone. First it was restarting again and again itself. I dont know what problem was caused. Then it stopped working and I tried turning it on but didnt turn on. Then also tried connecting it to the charger but a red light appeared for few minutes and then disappeared.

I tried different methods like connecting it to laptop and leaving it to charge for few hours but didnt work.

What probem is it? Is it that I should try replacing the battery or what? need help

Its been a year since I have bought this phone.
