Apple Admits iPhone 4S Battery Problems

Apple Inc. (Nasdaq: AAPL) has copped to a battery life issue on the iPhone 4S, saying that it is caused by the iOS 5 operating system and that a fix is on the way.

"A small number of customers have reported lower than expected battery life on iOS 5 devices," Apple said in a statement to AllThingsD. "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."

Some users started to complain to Apple and in online forums about the iPhone 4S draining its battery within a day even with moderate use. Apple had promised that the 4S, launched in October, would offer longer 3G talk time than its predecessor. (See Apple's Latest Is a Faster 3G 'Worldphone' and What Might Shorten iPhone 4S Battery Life?)

If the battery life issue is down to a software bug in the latest operating system, then iPhone 4 and iPad users that upgraded to iOS 5 could also be experiencing battery issues on their devices. LR Mobile would be interested to hear from readers who have upgraded about their experience with battery life.

If only I knew!


I've switched off location-based time updates, minimized iCloud back-ups, taken away the new notifications -> these helped, but the net result seems to be the same features as iOS4 but worse battery life. I look forward to the s/w fix!

My iPad 1 now running iOS5 - battery life very noticeably degraded, maybe halved.

Battery life seems to drain more quickly on iPhones and iPad 3Gs under iOS 5, if you have "Notifications", "iCloud", "PhotoStreaming", or "Location-Based Time Updates" enabled.  These services routinely contact Apple servers via WiFi or 3G to receive "Push Notifictations" or sync your iPad photos, etc. to iCloud.  "Location-Based Time Updates" is perhaps the worst battery draining feature as it continuously searches for new GPS time updates.  Turning all of these services off resolves the issue.


There could be longer term issues with Apple's entire iCloud strategy as carriers move to cap or meter the data services they provide.  Enabling Notification, iCloud, PhotoStreaming, and other real-time services such as these could result in consumers being charged extra unanticipated usage fees by their carriers.  Right now, these Apple real-time services offer an "all or nothing" approach to enabling what gets synced and what doesn't.  Those with large photo and data stores on their devices might have to opt out of the program in order to keep within their carrier's normal service usage guidelines.  Better user controls as to what gets synced or shared and how often would go a long way into resolving this.
