When charging a phone wirelessly, there is sometimes significant heat generated. That combined with higher charging rates that are now coming out with the Qi 2 standard make me wonder what the ideal charge for the battery would be.
Most of the time I just toss my phone onto a wireless charger before bed, and don’t really care how quickly it charges. Would it be better to use a 5W brick with a charging pad? Should wireless be avoided and usb used instead?
Unfortunately, while the law is certainly an improvement, it’s not as good as the headlines have misled people to believe.
Anybody who thinks they’ll be popping the back off their phone and changing the battery like it’s 2006 will be disappointed.
The law stops the most egregious stuff (like glueing the battery down excessively in a way that requires specialised tooling to remove), but that’s about as far as it goes.
A confident tinkerer shouldn’t have an issue. But it’s a far cry from what many seem to think the law is.
There are also exceptions. If you guarantee the capacity being over X (I can’t remember what the law stipulates) after 3 years, the battery doesn’t have to be removable. And IIRC, it’s not a particularly ambitious amount. Like 74% or something.
I think everyone likes to glue down batteries now because that helps the phone’s drop protection. The adhesive strips aren’t so bad since you can heat them a little / use a spudger to get the battery out. It’s worse when they make it very hard to get to the battery, or make you unglue delicate parts like the screen. You are probably right to be pessimistic though.
