Hello to all the community.

First of all, I am a total noob in the topic of cell phones and devices. I joined this forums to look for some help. I really don't know about the terminology of cell phones so please be patient with me

I think that my phone currently needs some kind of maintenance. Battery last less than a day and phone is a bit laggy. I currently have no root permissions on my phone (never tried to root it).

My phone information:

Model: C6502
Android version: 4.4.2
Kernel: 3.4.0-perf-g32ce454 BuildUser@BuildHost #1 Wed Apr 9 16:52:42 2014
Build: 10.5.A.0.230

What should I do from the start? What can I do with my phone?
Thanks in advance.
Regards.
