The Chevy Volt has the perfect handling of this: A new car never charges past 90% or drains below 10% battery. It simply reports 100% when the actual battery isn't quite full and vice versa, extending the battery life significantly. As the battery life degrades over time, it will try to keep the same useful range, and shrink those boundaries until you are using the full battery life each charge. Perhaps this works le…

I've never understood why these companies don't just add a redline: make the battery chargeable to 110%.

By default have it stop charging at the recommended 100%, but let the user decide if they need that to go beyond that and are willing to damage their battery health to do so.

As mentioned in the article, this has been an automated feature since iOS 8: https://support.apple.com/en-us/HT210512 Looking at my battery history, the automated version has my phone sit at 80% all night, and leaves it at 100% for only a couple hours in the morning. I suspect this will be a fairly negligible impact on battery longevity for me, and most users, without the severe inconvenience of a 20% reduction in ba…

Unfortunately, it's not possible to reliably automate this. A phone has no way to tell how it will be used after getting charged. It can try to detect some usage patterns, but it'll just be guessing, so even in the best case scenario it must remain conservative. This is one of my pet peeves - obvious and easy to implement features that are just not there. I literally only switched to iPhones because the blindingly ob…

Another example that this feature doesn't work is charging at car. In other words, it may work only while sleeping at night. It's far better than nothing, but I wish the 80% limit feature is available for my 13 mini.

This is just an optional feature, nobody is forcing you to turn it on, or to care about it. Personally I rarely need a 100% charge: my iPhone 13 easily gets through a typical day with 40% remaining. But I do get annoyed when a phone is 2 or 3 years old and the battery is already worn out. Genuine iPhone batteries are expensive, and limiting charging to 80% will significantly extend their life. Worn out batteries don'…

While not ideal, maybe we could have more trickle chargers? My worry is that the battery actually gets used often but for short periods and that could effect long-term wear. Personally, I have a Shortcut to put my phone into "low power mode" once it hits 90% (why not?). Maybe a Shortcut could do the same and turn off power once it hits 80% on your overnight charging dock and then use a small amount of power while the…

Isn't low power mode for when your phone has very little battery left? I don't understand why one would put a phone in low power mode when it's charging and hits 90%.

I can't imagine caring about this honestly. The way i feel it is like constantly caring if your white shoes are dirty, i only trust my shoes to help me walk. Technology should be as transparent as possible in my opinion and not bring us back to thinking about said technology, just what we can do with it. It's tiresome enough to worry about having a charged phone, i couldnt bring myself to look at battery percentage o…

I realize this is true, and sometimes I will charge sooner or stop charging earlier to keep my phone in this range. But most of the time, I just use my phone. After all, what's the point of optimizing the total battery life if you aren't ever going to actually use the battery to its capacity?

If you don't ever use the full capacity of the battery, why wouldn't you want to optimize it?

Because it's one more thing to think about?

Thanks Tesla for bringing about lithium battery health awareness to the masses. Without it I would be charging to 100 every night. And blowing out my battery way too soon.

It's very different when you are dealing with a $1000 object versus a $40000 object, where the replacement of the battery could cost $300 and $20000 respectively.

Are we talking about phones and cars here? What phone costs $300 for a new battery? I assumed Apple would be on the high end, and they charge a fraction of this ($100ish, IIRC).

That's the original intent, but there's nothing stopping you from enabling it whenever to try to get the absolute max possible out of your battery. Low power mode does sacrifice quite a bit of functionality by default though.

Personally, my 15 pro can do >72 hours on a single charge WITHOUT doing stuff like this, even starting at 80% (note: mostly standby, no always on display, with ~3h screen on time total). The 80% limit is definitely something I'll be using virtually all the time.

Oh sure, I put my phone in LPM sometimes when I know it's going to be a very long day. But why would someone put it in LPM when it hits 90%? Is that referring to when it charges up to 90%, or when it's in use, unplugged, and is "down to 90%"?

I have an iPhone 13 mini as my "work phone "and it's indisputably a fantastic, efficient, small phone. However, I am kind of OCD about keeping it between 40-80% charged, which is a lot of manual toil. Conversely, I also have an Android Galaxy S22+ for my personal phone. The "Battery Protect" feature limits charging to 85%. Life is easy with this device and it causes me a lot less anxiety. Really now, why can't Apple…

Fellow OCD-ish charge watcher here. Has worked great for my aging iPhone.

What grinds my gears though is the AirPods. I have AirPods Pro that I want to last a long time, but out of the case the earbuds are always 'on' and drain battery relatively quickly (much faster than a phone left idle); put them in their case and they're almost always* charged to 100%. I want to be able to leave them out, off, and disconnected. I almost never need 100% battery in my day-to-day use and there's no replacing the batteries in them once they're worn out.

An 80% max charge limit would be great.

*They do offer 80% overnight charge protection, but that's irrelevant as I don't keep them plugged in overnight

The new 80% charging feature (that’s limited to iPhone 15 models) doesn’t try to be as smart, and simply works all day long. That’s not how the Optimized Battery feature works, according to the help text displayed right next to the feature in the Battery Health settings. I question the whole premise of th…

Author again, “I question the whole premise of the article”

What? You got tripped up on my wording, sorry. But the article's premise is valid, and it's not cool that the top comment on this submission for its first three hours on HN has totally lacked curiosity and come to a sensationalist conclusion. Do you have any actual problems with the article? Could you list them? (You responded to others but not my previous comment)
