It seems that the update that Apple has launched a few hours ago, 5.0.1, is not giving the promised results, since many users are still experiencing high battery consumption of their terminals (reaching 2% loss just by opening Safari, or lose 20% of battery in an hour and a half and without touching the terminal).
As we can see in Apple’s support forums, it seems that the update that Apple released a few hours ago, iOS version 5.0.1, does not fulfill what it promised: to solve the problem of the fast battery consumption of the iPhone 4S (among others).
Some users complain for various reasons, such as the fact that simply opening Safari consumes 2% of the battery , or that only an hour and a half after the device has been updated it has already consumed no more than 20% of the battery.
On the other hand, I could check how the update via OTA (less than 50MB as opposed to the more than 600MB downloaded by iTunes to update the same device) works in a splendid way . Despite this, it seems that some users have not been able to update via OTA because they have less than 50% of their battery charge remaining (I guess most of them, iPhone 4S users). Personally, I have to say that I had only about 18% charge, and although the device has recommended me to connect it, it has updated without any complaint from the iPhone.
We think Apple will have to do something about it, otherwise they could substantially decrease their sales of their new flagship device: the iPhone 4S.
I encourage you to tell us your experiences in the comments, both in terms of battery consumption and updating via OTA.
UPDATED: Some users report that when installing iOS 5.0.1, their devices forget the names of the constants when receiving calls or messages.
