Apple confirmed some users are experiencing “lower than expected battery life on iOS 5 devices” yesterday, and promised that a software update can be expected in the next few weeks, which should wipe the problem clean. Can’t wait that long cause your battery drains too fast? Below, a few tips to save your battery life until the problem is resolved.

• Lower your screen brightness — Just like on your laptop, you can lower the screen brightness on your iPhone to increase battery life. Just head to Settings > Brightness to adjust.
• Use WiFi where you can — Instead of downloading apps, making Google Voice calls, or browsing the web over your cellular or 3G connection, find a WiFi hot spot or use your home’s WiFi network instead. This will keep your data charges down and will improve battery life since your phone won’t be searching for a data signal.
• Block GPS tracking in apps — If you’re using lots of apps that include automatic GPS location and tagging (à la Facebook, Instagram, and Twitter), your phone is working overtime to locate you. If you don’t need to geotag your posts and updates, keep the GPS off.
• Turn your iPhone’s “Fetch” and “Push” off — I have my iPhone set to “fetch” my data every 30 minutes and a ton of apps set to push new messages and alerts as they happen. This is great for keeping up with news and messages when I’m at home, but bad for your data and battery. To turn your “fetch” functions off on your iPhone, just go to Settings > Mail, Contacts, and Calendars > Fetch New Data > Manually. You can also turn off your email and calendar “push” from this screen. To turn off app “push” notifications, head to Settings > Notifications, then switch to off.
• Shut down apps often — Do you shut down your apps after you’re done using them? If not, you’re using up lots of battery by allowing those apps to run. To shut down apps after use, double tap on the home button to get to your app drawer. To close open apps, just hold down on one until you see the wiggle, then click on the “X” to shut down.
