At the end of the day there&amp;#x27;s a fundamental tradeoff that Apple needs to make on behalf of their customers: performance or stability. They chose stability, and I think they have a convincing argument as to why: &amp;quot;It should go without saying that we think sudden, unexpected shutdowns are unacceptable. We don’t want any of our users to lose a call, miss taking a picture or have any other part of their iPhone experience interrupted if we can avoid it.&amp;quot;&lt;p&gt;I have two concerns:&lt;p&gt;1) They still haven&amp;#x27;t fully eliminated the sudden shutdown behavior. My old 5S would shut down randomly under 20% without warning. Sometimes it would make it all the way to 1-2%, but most of the time it was between 5-15%. You&amp;#x27;d think they&amp;#x27;d scale performance throttling untilt this wasn&amp;#x27;t an issue.&lt;p&gt;2) I think their messaging with respect to battery health and the battery being a consumable is pretty poor. As far as I can tell there&amp;#x27;s no built-in battery health indicator in iOS. Sure there are those dodgy &amp;quot;Super Battery Health Plus Pro&amp;quot; apps, but it seems like a diagnostic menu in settings would go a long way. Even more puzzling is that techs at the Apple Store have access to some sort of diagnostic that does this already. Last time I went to get another issue fixed the guy said that my battery was at 70% capacity and the voltage was pretty low. Why wait until &amp;#x27;2018&amp;#x27; to ship a self-serve version of this?</text></item></parent_chain><comment><author>polack</author><text>What people are missing here is that while Apple now confess that they did slowdown the iPhone 6 and 6s when they released the 7, they are not saying anything about earlier models.&lt;p&gt;They are however lowering the price to exchange batteries even for older models. Why would they do that if they where not affected? Why don&amp;#x27;t they say this practice started with the IOS 10 update? They just say they did it in the 10 update. For me it&amp;#x27;s obvious this is just a PR &amp;quot;puff piece&amp;quot; and looks like a majority here is buying it... So well played Apple.</text></comment>
