Comment on New breakthrough may let us charge smartphones in 60 seconds

That is another matter altogether. Apple has that feature that limits the charge to 80%. Easily done. In fact, as we move to AI, we can create much more intelligent charging schemes that can be tailored to the user.
But when it comes to actual charge times, obviously less is better. Not sure why anyone in their right mind would get upset over lower times and claim that things are fine now. It’s like fighting against electricity because you love your typewriter.
Thing we’re unnecessarily shoehorning AI into #2985490385343: Charging a battery
Android already does that, no AI required. Some fairly simple math is enough.
The device first charges to 80% and holds there. It also calculates how long it will need to charge from there to full and when it will need to resume charging so that it will hit 100% just before the next alarm goes off. Then it does that.
Yea, tho, with fast charging like this. My single 33w charger already makes devices hot, this could cause that too
If it doesn’t come at the expense of battery wear, then sure, lower charge time is just better. But that would make phone batteries the only batteries that don’t get excessively stressed when fast charging. Yeah, phone manufacturers generally claim that fast charging is perfectly fine for the battery, but I’m not sure I believe them too much when battery degradation is one of the main reasons people buy new phones.
I have no clue how other manufacturers do it (so for all I know they could all be doing it right and actually use slow charging), but Google has a terrible implementation of battery conservation - Pixels just fast charge to 80%, then wait until some specific time before the alarm, then fast charge the rest. Compare that to a crappy Lenovo IdeaPad laptop I have that has a battery conservation feature that sets a charge limit AND a power limit (60% with 25W charging), because it wouldn’t make sense to limit the charge and still use full 65W for charging.
Fairphone 5 can force slow charging via settings. I use it all the time because I usually charge over night and it helps preserve battery life.
If you have root, you can try acc magisk module. I can set charging treshhold and limit charging current with it.

That exists. It’s called adaptive charging.

It has been available in some form since Android 11. It’s no longer limited to Pixels - my Motorola has a similar feature caller optimised charging, which doesn’t even require alarms. LineageOS also has lile 3 different ways to limit charging. In short, you definitely do not need root.

It doesn’t slow charge, at least not on Pixel 7a. Well, you could argue whether 20W is slow charging, but it’s all this phone can do.
It just charges normally to 80%, stops, and then resumes charging about an hour or two before the alarm. And last time I used it, it had a cool bug where if it fails to reach 80% by the point in time when it’s supposed to resume charging, it will just stop charging no matter what the current charge level is. Since that experience, I just turned this feature off and charge it in whenever it starts running low.

Can my grapheneos pixel 6a do it? I’ll try tonight
