Here's what I meant by the first statement commenting on Apple's transparency, or lack thereof. I was disappointed when we discovered this, to realize that this was a change that Apple had introduced with basically no notification to the user. I think when they changed the performance, when they changed the way the phone functions in such a fundamental way, that should have been transparent to the user from the very beginning.
Also, if the battery was degrading to the point where it was affecting other functions on the phone, to have some sort of notification on the phone that would indicate that this was the case would have been great. We had users who'd gone through and said they were experiencing the slowdown. They'd go into the settings application on their phone to look to see whether there was any sort of report to advise people to take their phones or their batteries in for servicing, something which Apple does on other products that they provide. Their laptops, for example, will indicate if your battery is outside of spec and should be replaced. There were no notifications in this regard on the iPhone.
This was very much done under the radar without any real disclosure to customers that this was happening or what steps a consumer could take to either mitigate or remedy this sort of issue.
I would make another comment on encouraging consumers to continue to update their phones. When Apple releases new iPhone software updates, these software updates can include unfortunate changes like this which could affect the way the phone operates. They do also, however, include important security updates. If a user refused to update their phone, they could leave themselves vulnerable to various security issues which could cause nefarious third parties to compromise their phone, their personal information, their banking, and any sort of information that might already be on their phones.
I think as much as consumers have lost some trust in Apple, and the contents of their updates, I think it's still important for consumers to continue to apply the updates for these security reasons.
