However, since its release a number of users have taken to Apple's support forums, claiming that since running the new firmware, they are experiencing problems with battery drain on their devices.
Whilst the WiFi issue may have been fixed for some, others are since reporting that where previously they had no issues, their WiFi connection is now unreliable.
One poster on the Apple support forums said: “I can usually get through a day with about 75% of my battery power remaining. Today I've gone through 90% and I've done nothing special with it.” Another poster commented on having similar issues: “....the update introduced WiFi issues and made the battery drain issue worse”. “Before updating to iOS 6.0.2 last night I never had WiFi or battery issues at all. Would easily make it all day with general use (Facebook, texts, phone calls) with ending up with 40% at the end of the day before recharging. Today I barely used my phone at all, and I noticed I was down to 40% after 4 hours of being off the charger,” commented another user.
The issue seems to be only affecting a few users; others are reporting that since updating their phones the WiFi problem has been resolved, and that battery drain is not noticeably different to before. This just highlights to variant nature of bug fixes in iOS, and how difficult it can be to resolve problems that are sporadic in nature.
