Since upgrading to iOS 6.1, have you noticed that your iPhone is losing battery a lot quicker than usual. Well, you're not alone. According to The Next Web, one user is experiencing a faster battery drain and that thread has 157 replies. If this is sounding all too familiar for you, then listen up!

A possible theory out there is attributing the issues to Apple Mail and Microsoft Exchange. As  Michel de Rooij points out:

"It appears iOS 6.1 is throwing up malformed meetings, causing devices to get into a sync loop which in turn causes excessive transaction log growth on Exchange mailbox servers. This then leads to Exchange performance issues and transaction log drives can potentially run out of disk space."

Of course, this is just a theory and it may not solve your problem. But, another alarming story is that MacRumors said that Vodafone UK is texting anyone with an iPhone 4S and instructing them, "If you’ve not already downloaded iOS 6.1 for your iPhone 4s, please hold off for the next version while Apple fixes 3G performance issues. Thanks.” Hmm. Makes you wonder, doesn't it?
