iPhone owners bemoan battery drain, Wi-Fi issues following iOS 6.1.3 update

Tools

Battery drain issues are once again plaguing some iPhone and iPad owners following the release of Apple's (NASDAQ:AAPL) new iOS 6.1.3 software update, with some consumers also blaming the release for issues with Wi-Fi connectivity.

Apple issued iOS 6.1.3 last week to fix a security vulnerability allowing users to bypass the lockscreen and gain unauthorized device access. But on Twitter and Apple's own Support Communities forum, users who've downloaded the update say their iOS devices are now experiencing severe battery life problems.

"Last night I updated my iPhone 4S to iOS 6.1.3 and now it drains my battery in an extremely fast manner," one consumer writes. "As I started signing in to write this question from my iPhone I already lost 13 percent of my battery. I never had a problem with a battery, and I've been using iPhones since the first one." Another commenter adds "I am too losing one percent of battery every few mins. I've completely erased all content and settings and started as new, but it's still no good," while still another states "I had to charge my phone TWICE yesterday and I hardly used it."

This is not the first time consumers have voiced their frustrations over iOS battery life: Following the release of iOS 6.1 earlier this year, some iPhone 4S owners soon began complaining the update accelerated battery drain and prompted some overheating issues. Apple responded with the February release of iOS 6.1.1, but battery woes persisted, necessitating the launch of iOS 6.1.2, which Apple said "fixes an Exchange calendar bug that could result in increased network activity and reduced battery life."

In a separate Apple Support Communities thread, consumers are citing iOS 6.1.3 as the culprit behind Wi-Fi connectivity glitches. Wi-Fi issues date back to the fall 2012 release of iOS 6.0--some users said iOS 6.1.2 fixed the problem, and while a segment of the user community blame iOS 6.1.3 for rekindling the glitches, others say the update has resolved the issue.

Apple has not yet responded to the latest battery and Wi-Fi complaints.
