My mobile will automatically restart

[Loveboy]

Hello Guys!
Maybe you know something the technic about the mobile.
My mobile will automatically restart, i just do nothing wrong, it just restart.

More details:
I make my mobile on -> i write my PIN (At this moment it can restart too) -> I am on it and can do what i want -> wait a little bit -> change to blackscreen ( automatically ) -> restart -> mobile is on. And this happens all the time again.

Do you know how to fix it?
I don't know why, but it maybe need a new battery..?

A bit more details on your specific mobile would be nice, exact model? os?

It might be due to software as well as it could be something wrong with battery, I would recommend backing up your files and then reset your device to factory settings and if that doesn't help it is rather battery causing your problem.

I have kinda same problem with my phone. Sometimes it just shuts off, even when I'm surfing/typing with it.

Model: HTC Titan OS: Windows Phone 7.5

I think battery isn't working well and I'm going to buy a new one.
But the problem appeared right after the OS update (WP7 --> WP7.5) and I got the update through a glitch before the official release, and I can't update it anymore because it says its already installed.

I hope its battery's fault.

So after I tried to reset my mobile, it worked.
After two days as I played with it and do all things on it, no automatically restart.
Thank you Yuri!

No, problem man.
And for others, if you're thinking of getting a new battery try this first so you don't need to spend any money just to fix it.
