IPhone 5 iOS 6.1.4 battery life

Anyone Else has experienced that Sometimes the battery drains quick? Anything to fix it?

My boyfriend had the same problem. He googled it and found a lot of tips to save his bettery. One was to turn down his phones lighting. Google it and try it out! His battery is great now, lasts much longer

No problem for me. The major problem for me was with iOS 6.0.1 & 2. Before & since, no problems.
