Is not happening to me. Been running iOS7 for almost 20hrs and all is fine.

Uhm, I think you can. If you mean attaching more than one file at once, yeah it still doesn't do that.

My battery life remains the same as before running the iOS6.1.4.

I noticed it did get hot a bit during the update and verification process but after that, it's temp is normal.

Tips:
don't clutter your phone with unused apps, it eats away battery life. Close them if you're not using them at the moment.
Turn off bluetooth if not in use, and limit location services to apps that really needs it.
You can also have the mail manually update, so it doesn't go fetch everytime.
Turn ON auto brightness and put the brightness slider on 1/3 to 1/2 setting.

That's how you save battery life.
