Just build phones with the understanding that batteries are consumables and make them easy to replace and standardized. Then swap in a new $5 battery when you need to so. Make the raw materials reclaimable too of course.
But the point of making batteries not easily removable (besides the waterproofing factor) is that when a repair shop charges them $150 to do it, lots of people will justify putting that money towards a new phone instead.
As someone who works on phones as a hobby, I've seen that the percentage of people who will either hire someone to do it or buy a different phone is near 100. It's absolutely an intentional planned obsolescence.
Waterproofing is a lame excuse that I won't accept from these manufacturers. It may be not as easy as just permanently gluing the thing together, but it's definitely possible to have a sealed battery compartment.
It was probably abused. I've never had a phone get that bad and I really do not think that is some widespread thing. Otherwise you'd see a lot of three year old EVs with a 20 mile range.
My last phone did this unfortunately. The battery just shit the bed and it would no longer hold a charge for very long. It was one of the last Nexus phones. It was like that for like a year before I finally replaced it. It was very inconvenient.
I get the feeling it has to do with how wireless charging works. On a wire, a phone can regulate how quickly it takes charge or whether it does at all. I don't think phones are capable of that with wireless charging, which is exclusively how I charged my pixel 5 at night.
So it would get to 100% and stay there for several hours every single night. I didn't realize it was bad at the time.
It could always just be that I was unlucky and got a defective battery to begin with. No way to know for sure.
Abuse or defects or environment. I've, for example, seen one phone which was constantly woken up (technical term in case it sounds odd) because of some event in the wireless signal and that made it use up the battery in a ridiculously short time. It was a combination of the way a network was set up, bad signal quality, and a firmware quirk. Clearly a defect, but hard to say whose. Forcing it to use some mode in the radio via settings circumvented that.
No. People online have really misrepresented that bill.
All it says is that it should be easily replaceable by someone of moderate skill. I.e. still having to pry open your phone carefully, but now without using strong adhesive.
It also doesn't apply for phone batteries over a certain size, or batteries that will still retain a set amount of capacity after a few years (I think 73%).
People are heavily, heavily mistaken if they think it'll be a return to the days of trivially removable batteries.
The biggest barrier for "most people with moderate skill" is having to acquire equipment to replace the battery. Once it becomes too much effort and cost it's better for most consumers to take it to the manufacturer or 3rd party service for replacement.
I stopped replacing batteries once I needed to heat the adhesive to remove the back and screen as I don't have that equipment to hand, and initial attempts caused damage to the screen and back cover.
You have an older Pixel or just rooted, maybe? My 7 on the latest vanilla Android doesn't seem to have it, and this thread seems to say it's not available in the stock os.
Ah, I see. I was focused on the 80% limiter for that "Maximum" setting, which I think is not an option on Pixel. But I see now that "Adaptive Charging" sounds like it does what that middle setting "Adaptive" does.
"Sleep time is estimated based on your usage patterns"
These systems exist on pretty much all modern phones, but they all work the same (shitty) way, by assuming your schedule is exactly the same every day and giving you zero programmable control.
And on iPhone the system expects you want your battery to charge over 80% on a daily basis. On a Samsung phone the system knows you don’t want to go past 80% at all, so it sets that as the new maximum.
To be clear, you are still taking about rechargeable batteries right? I agree those should be replaceable. I sure as hell don't think phone should use single use batteries!
