Earlier this week, Apple seeded the iOS 6.0.2 software update exclusively for the iPhone 5 and iPad mini. The minor update was issued to fix bug fixes, most notably an issue pertaining to Wi-Fi on those two new devices. But, as usual, some early adopters of the latest iOS software update are complaining of poor battery life.
I have yet to have any battery life issues on my iPhone 5, which has been lasting just as long as it usually does after updating to iOS 6.0.2. Nevertheless, several users are hitting the Apple discussion forums to complain that the update is draining their battery life faster than before.
One iOS 6.0.2 updater said that “I can usually get through a day with about 75 percent of my battery power remaining. Today I’ve gone through 90 percent and I’ve done nothing special with it.”
Another said: “Today I barely used my phone at all, and I noticed I was down to 40 percent after 3 hours of being off the charger. This is a significant change in battery drain.”
The issue does not appear to be universal, so you may not be experiencing poor battery life. But, if you are, it may be related to the new Wi-Fi behaviour as part of the software update. Let us know in the comments how your iPhone or iPad mini battery is holding up.
