[eminem619]

Which consumes less battery....my zenfone 5 battery is poor....i want to know i should upgrade to kitkat 4.4 or not....main reason for me will be better battery

Well 4.4 will be better optimised but you won't see any drastic improvement. Maybe 10-15 mins extra usage time?

Why don't you buy a portable battery or a battery charger case.

According to this website, kitkat will use less power. But to be honest, I don't think there's much difference between the two. The display is where most of the power will go to, and that has nothing to do with the android version.

Disable all unnecessary things -- GPS, WIFI, Bluetooth. Minimum screen brightness. Those are the primary things you can do to improve battery life.

Then you just have a poor battery. An external battery pack and USB cable is probably your only option for decent runtime.
