Apple iPhone 5 and iPad users on iOS 6.1.3 are having some battery drain issue, according to reports posted to Apple Support Communities. Other users are saying they are not having an issue at all, which results to some arguments on the support site. Here is a round-up of what's being said about the latest Apple iOS update.

Apple Support Communities user GregK75 wrote his iPhone 5 was working fine before he updated its OS to iOS 6.1.2. He later contacted and was advised by Apple to wait for the next OS update. He updated to iOS 6.1.3 but the battery problem persisted. "Just got off the phone with Apple yet again and was told yet again they are aware of the issues and are working on it," he wrote. Greg then reacted to some users saying the reported batter problems are not OS-related. "(D)on't tell people it's not an update issue when clearly it is. If Apple admits it, then why are you here saying it's not an update issue?"

"Well, my iPhone 5 is fine, as is my wife's, my boss', his boss, and everyone else I know who has them," wrote user KiltedTim. He is one of the users who are not experiencing battery drain issues after an OS update.

"My wife's iPhone 4 still has 6.1.2 on it and can get way more use out of it before the battery dies than I can from my 4S [with 6.1.3]," wrote user Malc7921. "And before anyone says 'but they are different phones,' battery life between the 2 was comparable and similar before I installed the latest update."

User Lawrence Finch offered a different perspective. "The real point is that any time you upgrade an iPhone there is a small chance that your battery life will change," he wrote. "It's probably caused by a process that got interrupted in the middle of doing something when the upgrade started."

The latest user to post on the iOS 6.1.3 battery issue thread, fzero187, asked for tips from fellow iPhone 5 users:

"I complained to Apple that my 4-month-old iPhone 5 was constantly draining battery life as experienced by many of you here. They said they would send me a replacement. Today it arrived and it is on iOS 6.1.2 (10B146). Should I update that or is it the 6.1.3 update that was killing the power?" (All quotes were slightly edited for easier readability.)

Check out the Apple Support Communities if you would like to share insights with fellow Apple iOS users. Meantime, we wait for Apple to release an official statement on the supposed iOS 6.1.3 battery drain issue.
