Apple's iOS 6.1 update for iPhone and iPad came with a myriad of issues including a bug that caused abnormal activity which led to intense battery drain. And while iOS 6.1.2 promised to fix them, it appears that even with the release of iOS 6.1.3 the battery life problems are still a big problem for some of Apple users.
Last week, the Cupertino tech titan released iOS 6.1.3 update to fix the securty hole that let anyone to access the iPhone sneaking past the lock screen. But, it seems like this update has some other glitches. According to a GottaBeMobile report, the battery drain issue seems to be persistent even after installing the new update.
Furthermore, there are complaints that the battery is draining even when the device is not in use. A user posted on Apple's support forum that the iPhone battery which used to show 99% after 12 hours started showing dead battery after the update. It seems that users are losing battery power at a rate of 1% every 7 minutes which is over 8% every hour.
Besides the battery drain issue, iPhone and iPad users are also facing some issues with the Wi-Fi connectivity. The bug grays out the Wi-Fi and hence, users are not able to connect to Wi-Fi signals. Eventually, this bug seems to affect the Bluetooth connectivity as well. According to Apple forum, Apple says that restarting the iOS device and updating it and then restarting the network settings by click on Settings → General → Reset → Reset Network Setting should handle this issue.
Certainly, it's possible that there will be another update to iOS 6.1 before the arrival of iOS 7, given the discovery of the iPhone's security flaw, but whether or not a battery life fix will be on board remains to be seen.
