iOS 6.1.2 fixes Exchange battery-drain bug

A small update promises to fix a bug affecting battery-life performance on some iOS devices due to a bug with Microsoft's Exchange technology.

Apple has put out yet another small software update to iOS 6 that addresses a bug that could cut device battery life.

This morning Apple put out iOS 6.1.2, a supplemental update that promises to fix "an Exchange calendar bug that could result in increased network activity and reduced battery life."

The update waspreviously rumored to arrive sometime this week by Apple news site iFun.

No word yet on if the update also closes a security exploit used by jailbreaking solution Evasi0n, which has become the fastest adopted jailbreaking tool ever.
