Re: Planned obsolescence
"So by this standard, I should just throw my 5S in the bin...."
Replacing the battery on a 5S is a piece of piss. Replacing the battery in my son's RC car remote is harder.
And for an out-of-warranty 5S, there's no point paying for original Apple. A decent eBay battery will cost you $15 or so and your phone will be back to full speed in no time.
