The battery isn't the expensive bit. It's the:
1. Supply chain
2. Managing stock in stores
3. Distribution and maintenance of equipment required to change the battery.
4. Staff training
5. Staff salaries on site
It really annoys me that a friend of mine pays £1500 for their Mercedes to be serviced regularly at a dealer which seems to require absolutely no parts at all yet complains that apple are screwing them because their iPhone 12 finally needs a battery.
Only iPhone 16 Pro and 16 Pro Max batteries prices were raised, not other iPhone batteries.No, but Apple has one rate in the U.S. for battery replacement. Unfortunately the labor that is a component in that rate is based on the most expensive rates in the country. Apple is going to protect their bottom line. They are not a charity.
@cjsuk gave an excellent breakdown of the other cost considerations. And even that is at a very high level. There are floor space considerations, disposal/recycle costs, etc.
You're telling me
1. Supply chain costs
2. Costs to manage stock in stores
3. The cost of distribution and maintenance of equipment required to change the battery.
4. Cost of staff training
5. Staff salaries on site
are higher ONLY for iPhone 16 Pro and 16 Pro Max batteries and nothing else?
