If you're one of the millions of iPhone 4 and iPhone 3GS owners who have updated to iOS 4.3, you may have found the battery on your device drains noticeably faster that it did before. This isn't the first time Apple firmware updates have changed battery consumption, but luckily there seems to be an easy way to improve the situation.
Ping has been cited by Pocket-lint as a possible culprit on the iPad, iPod touch and iPhones running iOS 4.3. The software runs Apple's iTunes-based social networking service, which makes it possible to connect with friends and get related music recommendations. For those who use the service this battery fix won't help, but if you don't find Ping useful then you can turn it off.
