With all the talk about battery life, phone throttling, battery ageing, battery replacement cost....... why isn't there a massive tidal wave of us customers demanding that phone manufacturers return to producing phones with user-replaceable batteries?
Especially in usage scenarios involving a full charge every day (ie., 350 charge cycles per year), battery wear out is a given.... and long before the phone is obsolete.
Apple's offer of a $29 battery replacement is a good move (and comparable to the cost of a user-replaceable battery), but that low cost is only temporary for one year.
And finally.... if you think manufacturers made money on your phone, you would be shocked to see what they are making on a $79 battery replacement that consists of a $2 lithium cell, a small cable and connector and some shrink wrap.
