Last week, Apple engineers were reportedly looking into complaints about unexplained iPhone 4S battery drain. On Wednesday, the company officially acknowledged the problem and said they are currently working on a fix.
Apple told Jim Dalrymple of The Loop:
“A small number of customers have reported lower than expected battery life on iOS 5 devices. We have found a few bugs that are affecting battery life and we will release a software update to address those in a few weeks.”
