Default Constantly rebooting

Hey there, I'm using a CM 10.1.2 rom for 2 days so far, and I'm not liking, it during a lot of battery, it heats like hell when I play for a bit and it reboot up to 4 or 5 just in Day.. I'm a new on hacking area but I would really appreciate to know what is the best to use on my device by the way it's Sony Xperia V.
