iOS 6.1.2 has just been released earlier today. Apple says that this update fixes the unnecessary extra network activity that iOS devices make to Microsoft Exchange servers which resulted in unusually fast battery power consumption.
Hopefully this update resolves most battery drain problems brought about by iOS 6.1 & 6.1.1.
iOS 6.1.2 has a filesize of about 12.8MB.
Don’t forget to make sure your device is plugged into a power outlet before updating to avoid complications and problems.
Lemme know if you guys have noticed improved battery life after updating and test driving the new version a bit.
