Much before iOS 7 was released to the public, we wrote about possible battery issues which happens with almost every iOS upgrade. Although we haven't faced extensive battery drain so far in any of our iOS 7 devices, I must also admit that the use hasn't been extensive either.
Nevertheless, these battery-saving tips will come in handy for your iPhone/iPad to last longer.

Dive right in:
With a radical new design, iOS 7 brings quite a bunch of visual redesign that does have an impact on power consumption. With things like dynamic backgrounds and parallax, the processor works a lot more than in iOS 6.
Reduce Motion in Parallax: One of the first things you can do is to turn off the parallax (background tilt) if you aren't very much interested in showing it off to your peers. It's a fancy feature actually.
To turn it off:
Go to Settings → General → Accessibility → Reduce Motion and turn ON the switch.
Switch to Still Instead of Dynamic Backgrounds: Dynamic backgrounds are great (not to forget that they're obviously inspired by Android) but here again is an opportunity to conserve battery. Thankfully, iOS 7 lets you opt a still background. Here's how to do this:
Go to Settings → Backgrounds & Wallpaper → Choose a Background → Still and pick one.
Reduce Brightness : Well, that's pretty easy and universal. Reduce brightness and conserve the battery.
Background apps, apps re-written for iOS 7, and automatic app updates that use Wi-fi or 3G which in turn affects the battery. Here we go:
Background App Refresh: Go to Settings → General → Background App Refresh and turn it OFF to prevent apps running in the background from refreshing automatically. It helps.
Kill Background Apps Occasionally: One thing that you can manually control is to quit apps running in the background often. Sometimes, when you've opened a ton of apps, you forget that they're all running in the background, eating up some memory which ultimately ends up eating up some battery-time.
Open the multi-task-switcher occasionally, swipe those apps up to quit them.
Turn off Auto-Updates:Auto-app updates are great only as far as you don't have a lot of them queued up for an update. Turning this off can be helpful. To do it:
Go to Settings → iTunes & App Store → turn OFF the switch for Updates under Automatic Downloads.
Test, Tweak, and Moderate App Usage: Some users pointed out that the redesigned Facebook app could be causing a battery drain. That isn't confirmed yet but there are also other apps that might cause a similar issue.
There is no set resolution for this other than testing and tweaking your app usage.
Network Location Etc.
This is the usual stuff.
Switch Off Wi-fi, Cellular Data When Not in Use: When not in use, turn off Wifi/Cellular Data (Settings → Wifi / Settings → → Cellular).
Turn off Location Services: The same goes for Location Services too. Settings → Privacy → Location Services. Turn off the switch.
