Recently bought an iPhone 4S, which is currently running IOS 7 (the most recent update) and the battery life is terrible. After fully charging to 100% my battery life had dropped to 14% after 2 hours and 15 minutes of usage. Is there anyway to fix this?!

Sony Vegas won't render MOV files?

I have taken about 7 videos on my iPhone 5S that I need to make into a project on Sony Vegas. I have put all the videos together, with a lot of trouble because the preview is so laggy and I have tried everything to fix it but nothing seems to work - when making videos the preview is never usually this laggy. I tried to render the project, but all that renders is the sound and a blank screen. I've tried all different settings for it to work, I've googled for a solution but I can't find anything. Could someone possibly help? It's really important!

Added (1). I forgot to mention that this is Sony Vegas Pro 12.0

How to delete a song on my iPhone?

I just purchased this album from iTunes however I don't want all of the songs. I held my finger on the song I wanted to delete and slid it to the left and it came up with a little red delete button and I pressed it but it just comes up with that cloud symbol and still plays the song anyway! So confused I just want the song off my phone! I have iTunes up on my laptop now too but can't find how to delete it on there either.

Thank you
