It's not that they didn't care, it's that they did care in the wrong way. A non-replacable battery means people will be more likely to buy a whole new device if (when) the battery fails.
The redesign is because the ease of accessing the batteries did not comply with the new rules. The pro controller in particular requires almost complete disassembly to get to the module, and the Switch 2's battery uses double-sided adhesive which is finicky. Joycons can also be a bit finicky to navigate for the uninitiated.
Also, as the device is Japanese, it uses JIS screws rather than Philips (in addition to triwing), which could surprise some. These are superior for service - Philips screws are specifically designed to strip during assembly to prevent over-torquing - but they do require you to have the right, "exotic" screwdriver. As JIS screwdrivers are compatible with and superior in bite even for Philips screws, it's a good habit to just always use those instead for electronics. iFixit kits and such include them.
Oh how far we fallen
why are you changing a USB port on a phone?
The original designs did not reference this though, so it seems more like them adopting an observed behavior as a feature - so the statement that it was originally designed to be that way is indeed off, but the company did adopt the behavior in official paperwork.
However, batteries cannot cost $1 unless you want $1 worth of battery. Modern batteries are genuinely complex devices with extremely tight assembly tolerances, and something like a phone battery should be expected to be more like 10-40 USD.
Cheapo cells exist, but they genuinely have issues like poor assembly tolerances introducing risks of it deciding to spontaneously transform into a pocket-sized smoke machine.
My understanding is that Europeans also generally tend to not use Phillips screws, but Pozidriv instead.
Philips in JIS screws is an exercise in anger management. IIRC, JIS has a much wider angle on the bottom of the drive, making it sink into the head less than a philips drive would, so it's a great way to turn your philips driver into an artisanaly-rounded single-hole punch.
The myth that JIS needs special screwdrivers is caused by people using either using the wrong size (easy at small sizes), using a worn-out or poorly-made screwdriver, or using Pozidriv (which is genuinely very different).
Anecdotally, about 5 years ago I bought a set of off-brand "premium" screwdrivers, where it turned out the Phillips head ones (yes there are two L's in there) were so far outside the standard I had to just throw them in the trash.
The Philips screwdriver has lobes with a large multi-stage taper that ejects the screwdriver from the screw upon torque. The JIS screwdriver lobes are in contrast almost perfect 90 degree angle with a tiny filet in the center - not dissimilar to the Frearson screw.
A Philips screwdriver will be unable to insert all the way into a JIS screw due to this taper, exactly similar to how the extra lobes on a Pozidriv screwdriver collides a Philips screw. Attempting to apply torque with this partial engagement puts you at very high risk of stripping the screw.
A JIS screwdriver however does work perfectly fine in Philips screws, often even better than the Philips screwdriver as you did away with one half of the "screwdriver ejection feature".
There's a reason that iFixit goes out of their way to make both JIS and Philips bits, and warn you in their guides. They aren't really in the business of trying to cram more bits down your throat for fun.
I don't think this is an issue for anyone who has had to disassemble a japanese device before, and the bits are widely available online. Countless youtube videos have discussed that JIS vs Philips in the consumer space are largely compatible outside of american aircraft construction.
But for electronics I basically never want that behavior.
Pozidriv to the rescue! (just kidding)
I celebrate user-swappable batteries and I think I like the battery regulations. I just don't think the Ghost of Iwata is under your bed twirling a Wario moustache while thinking about how to screw you over. The current Switch battery situation is simply a result of user-swappable not being a requirement, among the countless other requirements already in contention.
That's Nintendo's entire business model and the reason why they've been thriving since for ever in gaming and even the bad times where actually positive cash flow wise. They're not losing a single sale because the battery cannot be replaced, unless that sale was far from guaranteed to begin win.
Funnily enough, these regulations were made by policy makers who were voted in with votes, and put such a regulation to its own vote. It's the most democratic way to approach this.
Voting for politicians (if you even bother) who might someday vote for or against something like this is a far, far weaker signal, if any at all. Politicians can easily do things that are vastly unpopular - e.g. in the UK the mass immigration that is clearly deeply unpopular but politicians refuse to change it.
This isn't about the government being your nanny, it's about the government, long term, building a better more sustainable society for everyone, as it should be doing. And I don't think there's a reasonable objection to that.
I imagine the various products had their specific own conflicts with the rules, like requiring too much disassembly (the Pro controller in particular has to be disassembled from the front first), or the Switch 2 holding the battery with double-sided tape. Not to mention that you might not realize that the screw are JIS spec, stripping them with the Philips screwdriver you found in your drawer. Also triwing.
The market mechanism breaks down in such circumstances.
I have both a PS5 and an XBOX Series X. Whenever I am playing if I get out of battery on the XBOX, I just change them. In the PS5 is not possible.
I don't get what the advantage is.
Controllers have been using USB and an almost identical layout since the Xbox1 days 25 years ago, yet most game controller remain incompatible with each other, even within the same company. PS3 won't work on PS4 and PS4 won't work on PS5. Ironically, PS4 and PS5 controller will work on PS3, since that was the first and last console that supported plain old USB HID. Meanwhile Xbox360 had a lock-out chip to prevent third party controller and the Xbox360 controller don't work on XboxOne/Series either. XboxOne and XboxSeries at least are compatible. Meanwhile on PC pretty much everything works.
And then you have the whole stick drift problem, that has been solved since Dreamcast and PS3 SIXAXIS with Hall effect joysticks, but even decades later we still have controllers going in the bin due for easily avoidable reasons.
Rubber coating is another very common way to add an expiry date to devices that wouldn't have one otherwise.
If we wanted to get serious with the whole "Reduce, Reuse, Recycle", there are a lot more low hanging fruit than just the batteries.
Through a combination of internal and external factors, lithium batteries go through irreversible chemical changes on every charge cycle. Total charge capacity always trends down. Depending on a large number of variables, this might happen quickly or it might happen so slow you might never notice at all. It's all down to how and where the battery is used because temperature is mostly what drives the chemical reactions.
The other thing is that lithium batteries which have been deeply discharged below safe levels are permanently damaged. Just like charge cycle wear, this can be immediately apparent, or something that goes unnoticed forever, but the cell is damaged and will never be the same. Recharging such a battery can cause physical damage inside the cell.
Point is, batteries are chemical cells. They don't last forever because most chemical reactions are not perfectly reversible. Their specific application and environment strongly affects how long they last. But we do know conclusively that when lithium batteries are kept hot and charged and discharged at high current (such as in a handheld gaming device), they degrade faster. Cells which are kept at a stable temperature and low currents (such as headphones) degrade very slowly and can last a long time.
If you look past superstition, there's an entire industry that's been rigorously studying this problem for decades. There's a lot of literature and evidence.
Lithium cells do degrade. How fast they degrade depends on cell quality and environmental factors. It is, unequivocally, a question of when a battery will fail. It might well be a decade or two, but it will fail eventually.
I try to keep my cell phones as long as I feasibly can. Every single one I've used for more than 3 years has had its battery fail (as expected for a device that sees such heavy cycling). My current phone is on its 3rd replacement battery.
That said, this will get more important going forward, phone and tablet hardware updates get ever smaller and incremental, and longer software update cycles are another thing the EU is starting to regulate. So devices reaching 10+ might not be that unusual in the future.
And as an aside, the one type of battery that very frequently fail isn't the built-in LiPo, it's the good old user replaceable Alkaline AA and AAA batteries, and they don't just run empty, they leak and destroy your hardware in the process, even long before the expiry date and with charge left. It's so common that I am surprised that that hasn't seen any regulation or consumer protection jump into action. Using NiMH instead helps, as they don't leak.
And it was unnecessarily hard (actually dangerous due to fire risk) to replace it with a 3rd-party battery replacement due to excessive amounts of strong adhesive holding the battery in place.
The switch doesn't fast charge at absurd rates and generally has good thermals.
E: DS4 = DualShock 4, DS5 = DualSense; these are the standard PlayStation controllers for the PS4 and the PS5 respectively.
A good number of users will never hit troubles with their battery since electronic devices are treated rather cavalierly and replaced before those defects will surface, so I object to the wording that all users will hit that - but I still think it's clearly in the best interests of the majority of consumers to bargain for better lifetime extension support.
