How do I set power saving mode??

[#1]

I got a sola phone 2 days back I am happy with all features except for the battery... it drains out so fast... I am not using wifi, bluetooth, data sync at all even brightness set to minimum, bravia mobile not selected, just used the phone for 1 hour call and some messaging in between I find it lasts only for 6 hours or so after charging 100%.. If i start using wifi, data sync not sure it would last even 2-3 hours.. Let me know what can be done with this,

It's takes about one week for the Android system to optimize your battery life time and to configure itself for as long battery life as possible.

So I suggest that if you still have this low battery life time even after one week of usage you should try to repair the phone software.
