Surely you are capable of replacing a car battery. The main point is that a phone battery should be mandated that it is easily replaced like a few years back. Likely a laptop battery could be similarly done if Apple was foreced to make it so.
Was the phone design with battery compartment and cover much more user friendly? Not always.
• Device needed to be bulkier
— If not, you’re back to a convoluted/challenging battery cover and battery removable/install process. The only difference would be a lack of adhesive.
• Battery compartment doors could be lost or broken
— Tabs as securing mechanisms are dreadful at best — at least metal is more durable than plastic
— If it did break, there returns the need to interact with the manufacturer for replacement
Difficulty of the procedure aside, I do wholeheartedly agree Apple requiring the replacement of several components at a time (simply due to use of adhesives) is unreasonable. Apple does have tools and processes in place to deal with adhesive use in other products (e.g. iPhone, iPad).
To an extent — perhaps devil’s advocate -- I like the difficult to replace battery aspect. I am guessing it keeps people very susceptible to the placebo/lemming effect (e.g. “My battery is down to 96% health! It needs to be replaced!”) at least somewhat at bay.
Like with cars, 99% of consumers won't care about any of this at all. If their thing needs fixed they'll take it to a third party repairer (authorised or not), or the OEM's service centre.
We've got the best MacBooks that Apple have ever made, and if the "cost" of that is less end-user repairability then I'm okay with that. And just to be clear, I'm one of those 1% that will try and fix my own stuff where I can.
For me, it’s two main reasons:
• The result is (typically) better when the work is performed by someone with a lot of experience (and preferably passion)
• The cost often seems less if I delegate the task to an expert.
For example, I’ll normally replace the tire tubes on my bicycle, cleaning and general lubrication, as well as occasionally attempt some necessary adjustments. However, for the remainder, I take it to a local bike shop where they complete a full inspection and fine tuning within minutes. Could I learn and eventually accomplish the same? Sure. But, at least for this subject (i.e. bicycle), the time, frustration, and possibly additional costs of mistakes does not seem worthwhile in comparison.
Almost as if the whole point of Right to Repair is you have the RIGHT to REPAIR should you choose, and others have that right.
And now that the ability to repair exists, the whining moves on: it’s not cheap enough/free and it’s too tough/inconvenient.
The basic reality is nothing will make the complainers happy.
