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.

Earlier quoted context omitted.

Having the majority of your usage / charge cycles being based on a 50 to 80% total charged will increase the total cycles (and the battery’s total life).

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?

85% for daily, 100% for long trip

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…

If iPhones have replaceable batteries (the kind you can slot in and out) then you’d be right. Replacing an iPhone battery at an Apple Store costs about 1/3 the price of the phone by the time you need it replaced, so ideally one would want the battery to last as long as the lifetime of the phone. One way to delay liion battery ageing is to shallow charge. Case in point I’ve a 6 year old dell laptop that is set to shal…

>Most laptop battery stop holding a charge 2 to 3 years in.

Counterpoint. I have a lenovo thinkpad t480s that I bought second hand and is now 4+ years old. The battery lasts at least 6 hours. I haven't discharged it fully in a while to be more precise. Ubu 22.04 running in power save mode as selected from the default gnome menu.

Dell? Yeah, terrible company making terrible laptops for sure. Used to think differently before owning one.

It slows down and times its charging to reach the 100% right before you get up in the morning, rather than immediately after you plug it in (which would make it 100% all night long).

So in other words, the limiting only works overnight. So, again, what is the difference from what you quoted? Is it the implication that it might work at other times of day when the phone is "normally idle"? I don't even know if that implication is true or not, since it depends on exactly how the phone calculates your schedule. But if that's your complaint, it seems pretty small to me, not enough to throw the rest of…

Optimized Battery will charge your phone to 100%.

I have this feature enabled at all times, but my iPhone 15 Pro (with always-on display) usually can't make it through the day. Still wondering if limiting always to 80% will actually increase longevity of the battery

Deep cycles are also bad for batteries. Honestly, I’d suggest trying to use your phone less. A new 15 pro has a pretty ridiculous screen on time even at just 80%.

If GP is like me where I always run an app tracking my location (with my consent) in the background, even using the phone for 1 hour per day would drain the battery from 100% to 30%.

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 less will for phones, but I'm not so sure. Personally I never have issues with battery on new phones. It's only as the battery life shrinks that you really need the full range.

1/3 the price of the phone?

An iPhone battery replacement is $49-99 at an Apple Store.

Why not make 80% the new 100%?

Because there is a trade off here between ease-of-use day-to-day and long term longevity.

Battery is at least 20% too small then. The trade off with making it bigger is not for the user it's between engineering and marketing, which is dumb.

Right, once overnight is ending. It only optimizes overnight, with the battery limited the vast majority but not right at the end.

I don't see the conflict.
