"A small number of customers have reported lower than expected battery life on iOS 5 devices, " said Apple spokeswoman, Natalie Harrison as quoted by Business Week, Thursday (11/03/2011). "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" she added. However, Harrison declined to comment further about what might be causing the problem.
Related to the officially statement from Apple, the good news is that the problem appears to be due to a bug in the iOS 5 software that the phones use - rather than a problem with the battery itself. But the bad news is that the problem will take a few weeks to fix.
