As a consumer do I have to worry about this or will BMS handle things? My kid runs his 3DS until it shuts off and I was wondering what impact that kind of behaviour might have.
Charging a lithium battery to 80% only?

Re: Charging a lithium battery to 80% only?
#62I mean, it’s one thing to be believe that it is “too inconvenient” or that “life’s too short to micromanage my phone battery”, and another to blatantly spread lies that stopping charge at 80% is a “myth” with no benefit. And maybe that “micromanagement” argument was true 5 years ago, but nowadays nearly every device can automatically limit charge levels, e.g.:
iPhone 15 and above
iPhone 14 and below with a smart-plug[4]
Most Samsung phones/tablets
Sony phones/tablets
Any rooted Android
Any decent EV
Windows: Asus, Dell, HP, Lenovo, and Microsoft laptops
MacOS through AlDente[5]
Linux: TLP for most manufacturers[6]
And honestly if your device can’t automatically limit charge, I concede it probably isn’t worth the micromanagement. But those kinds of devices have small, cheap, and easy to replace batteries anyway.
It’s a heck of a lot different to drive to the Apple Store and spend $250 for a MacBook battery versus the $30 battery and half hour of work for Nintendo Switch.

Re: Charging a lithium battery to 80% only?
#63I've been using ACCA[0] for years to limit charge on my phone, usually to 60%, but higher when needed. I also limit the charging speed most of the time. It performs like new despite the phone being over three years old. I'm determined to keep it usable as long as I can because I prefer its size and analog headphone jack over what's available now. Actually replacing the battery, however looks like a big hassle, so I'm…
If phones with easily replaceable batteries arrive due to legislation, it would be one major win, less waste and more peace of mind.

> ”I kinda wish my EV would just set the apparent 0% and 100% points at a level that guaranteed X cycles, where X corresponds to perhaps 200K miles.” They already do! In most EVs, 0% is not really zero: you can typically drive another 20-40 miles before it finally dies. Most EVs will easily have a battery life of 200K miles, with some capacity degradation. Active battery management such as limiting the max charge is…
What happens if you actually do fully drain an EV on the road? How do you recover from that situation? Normally you’d just have to get a container of fuel delivered to you.
Some EVs also support power output (V2x) from their charge ports, allowing you to charge up one vehicle from another.

I've been trying a similar experiment for several years now. I have a four year old iPhone, and for most of its life, the battery level has been kept between 30% and 70%. Settings => Battery => Battery Health and Charging says that the maximum capacity is 91%. No idea whether that's better or worse than average, but I mention it so others can compare. I can say that this is the first time I've tried this experiment,…
Did you have an automated way to do that?

Cheap for the wallet, but not the biosphere. Unless you mean to imply that people would get new phones less frequently?
How is that all that damaging? I’m sure those batteries are recycled in basically all cases and yes, I’d expect battery replacement does indeed forestall replacement for many phones.

#67So I went to Amazon and bought a $14 kit that came with a battery AND tools. Did it myself in 15 minutes. (Whereas the UBreakIfix vendor took like 2 hours of my time between dropoff and pickup).
The Amazon battery has lasted longer than 3 Google official batteries did. Even so, I no longer worry about batteries when all these cheap kits and instructions exist.
Re: Charging a lithium battery to 80% only?
#68Does anyone know how limited charging works with balancing? As I understand balancing only happens when batteries reach their full capacity. A bit of background: Batteries are made up of cells which have ever so slightly different voltages. If you have three 3.7v cells in series to make a 9.2V some cells will be 3.68V and another could be 3.72V. This is bad, because when you charge the battery it is charged as a whol…
2. Balancing does ensure the capacity of all cells is maximized, but does not match each discharge characteristic under load.
Thus, the method can improve cell life under shallow changing, but can't atop unbalanced loading with random cell impedance mismatch.
There are good chargers and special meters that can help match a set of cells.
Best of luck =)

> Those are replaceable and cheap to replace every couple of years. If you specifically seek out devices with cheap replaceable batteries, sure. But this isn't the case with a lot of devices.
Replacing an iPhone battery is cheap, especially compared to replacing the whole phone: at the Apple Store it’s either $99, $69 or $49 and I’ve had other stores do it for like $40. That’s not too bad for a once every couple years cost.
That's not snark. I want things from my phone that an iPhone can't give me.
The battery replacement ecosystem in Android land is pretty dismal.
