Will the actual IOS 7 fix battery drain?

I installed IOS 7 beta last week and have noticed my battery is draining in a faster pace. Will this be fixed when IOS 7 is released this fall? And will I be able to download the actual IOS 7 from my iphone in software update instead of going on my computer?

Still beta version, I believe Apple has noticed this issue and the problem will be solved in the offical version in this fall

  • Battery on my iPhone 4S doesn't fully drain? My battery life is weird instead of draining all the way down to 1% it dies at around 12%? What can I do to change this? Or improve battery life overall?

  • Iphone 5 on ios 7 battery drain? So I have an iphone 5. Now my battery dies extremely fast. I'm talking it'll be on 100% and go to 50 randomly. It also cuts off on high percentages. My battery never goes to zero. It always just will cut off fat any given percent, typically a high one. What can I do to fix this as it is a serious problem
