using moto G almost over 2 weeks.

i dont know its a problem or not but not getting a good battery life. i mostly used Wifi and data connection for browsing and calling that to causally. but battery drain within few ours.

want to know its problem of battery or kitkat

Kitkat is not only better optimized with low RAM, it is also better equipped to efficiently use battery. Apparently you have some apps those are eating lots of battery power. You may try to uninstall unwanted / unused apps and see if it helps. Also, other thing is to reduce screen brightness.

Is that right from the beginning you are facing battery issue or started after some days ?

Hi, geekyms
ya do as Arish said because he is an experience person and he face this type of problem and then also u find problem then u have to go mobile engg.

hi friends
ya i also think that you have some apps those are eating lots of battery of your phone.

i used Greenify app to hibernet the process and also clean master to clean the memory. i not at such hard core game user but i used Wifi and 3G most. and continues used of Wifi makes battery live upto 2-3 hours only. in short i need to charge the battery atleast 2 in a day.

i attach the graph of battery life

Hmm..
So most of the time its mobile signal eating up battery, if you have wifi most of the time then disable 3G data as well you may also switch to 2G mode in order to save battery further. Also, just before this graph screen, it shows how much battery used per application level, what you see there?
