How to extend battery life?

[mlb71]

I have had my Xperia Z1 for a few days, but despite reading decent reviews about battery life, I only manage to get 4-5 hours of screen on time per full charge. I have stamina mode on, have x-reality disabled and have my screen at the lowest brightness setting. However, my screen is still consuming the most power, and android also consuming 9%

I'm running android 4.4.4 and have all the latest software upgrades. I've only used my phone for Facebook, Twitter, texting etc and I'm only using my mobile data (no wifi)

Any suggestions for how I can extend my battery life?

If mobile data is on all the time,you will get a reduced battery life. Also syncing all the time will get you to that.
