A number of other users have posted about battery life issues with their new iPhone 3GSs.
"My guess is there's going to be a whole lot of batteries affected because these [iPhones] are from very large production runs," Aaron Vronko of iPhone repair outfit Rapid Repair, told The Telegraph.
"If you have a problem in the design of a series of batteries, it's probably going to be spread to tens of thousands [of device], if not hundreds of thousands, and maybe more."
TechRadar has contacted Apple for further comment on this problem.
