Neither nor.

Li-Ion-Batteries last longest if they are kept between 40% and 80%
charging level.

The worst is draining to zero. That will kill Li-Ion almost instantly.
Also avoid longterm exposure above 35°C.

In the iPhone itself. It also controls the optimised charging.

It depends on the device and battery type. The advice for most devices
these days is to try to keep them charged in the 20%-80% range. Many
newer devices have software that won't let them be charged to 100% at
certain times and/or environmental temperatures anwyay.

It's far better to keep it topped off than to allow it to drain
significantly. iPhones have a feature called Optimized Charging that
trickle charges past 80% so that you don't need to worry about
overcharging even when fast charging.

CW: Keep the battery between 20% and 80%. Newest iPhone has an 80%
limit option. (Not sure why Apple didn't include the option for older
iPhones running iOS 17 ...).

You can also get apps and external charger to hold that on older versions

Unused phones: Store at about 50% (40%..69%).

Occasionally drain it to 0% solely to calibrate the charge level
monitor. (I do this accidentally at least 2x per year and that is all
that takes).

No. When a smartphone is indicating 0%, the battery voltage is still
well above the damage zone for Li-ion batteries. This point is about
2.8V per cell.

When a Li-ion battery gets somewhere below 2.5V, then damage may occur. Specialized battery charges can recover such batteries (this is not in smartphones).

So when you discharge to "0%" there is still a sufficient margin of
safety for the battery. Enough that even months of storage won't harm
it. (but in a smartphone there are likely other "loads" on there that
will deplete it within that time).

Thus I try not to let it get below 20% often, but I certainly don't
worry when it gets to 0% and shuts down. IAC - that's a calibration
point it learns for the battery meter.

Also avoid longterm exposure above 35°C.

Yes.

Li-ion chargers, regardless of the application, are designed to protect
against (All voltages for single cell batteries - or parallel cell
batteries). This is done by a device often called a "charge controller".

-Undercharge. When voltage gets to about 2.8V, the charge controller
isolates the battery to the open state[1].

-Overcharge. When voltage gets to about 4.2V, the charge controller
stops letting current flow to the battery.

-Load Short Circuit: should the load on the battery be too high, as in a
short circuit, the charge controller will isolate the battery to open state.

[1] Some device's charge controller (smartphones included) will
continues to supply power to some low current draw components while
denying power to the main device.

So this may explain why my new iPhone 15 Pro Max came at about 80%
charge in the box? Not knowing then what I know now, I immediately
connected it to the charger before setting it up.

If you own an iPhone, you're already doomed in terms of overall battery
life expectancy - because Apple cheated you on battery capacity. Big time.

First off, you're being advised by utter fools, where the most important
aspect of battery life isn't what _you_ do, but what the OEM did.

Your OEM, unfortunately, provided you with the crappiest battery it could
get away with (if you don't believe me, compare the capacity to others).

Given Apple gave you the crappiest cheapest battery it could get away with, you're already doomed to a low long-term battery life just because of that.

And I already know what the ignorant uneducated iKooks will claim, which is that when the battery is brand new, it "lasts all day" but what they can't
ever comprehend is that a new battery isn't the same as an old battery.

The iKooks have such a low IQ that thinking ahead by a year or two is completely incomprehensible to them... they'll just stutter...
"*bbbbbuuuuuttttt... it lasted all day.... at the very beginning...*"

Idiots. All these iKooks own a low IQ because that idiocy comes from them.

It's incomprehensible to the iKooks that how long a battery lasts when it's brand new isn't the same as how long it lasts when it is two years old.

In summary, you're being advised by idiots, where they have no
comprehension that you're doomed from the start because of Apple's decision
to cheap out on battery capacity.

Hence, your first choice should have been a phone with a better battery.

And that's not a problem. Apple designed iPhones to charge to 100%, and
they automatically slow charge past 80%. All batteries have finite

can be done while you wait. People who babysit their batteries and
purposely refrain from charging them past 80% are not only reducing
runtime, but are completely missing the point which is that you are
supposed to use and enjoy your iPhone as designed. Not only that, but
they are constantly maintaining awareness of their battery charge levels
and health which adds needless stress to their days. It's foolish and a
waste of time.

You are spreading FUD and absolut nonsense.
First calibrating is done at 100% not at 0%.
Draining to 0% is killing the battery with absolut certainty. All Li-Ion accumulators.

You are an idiot.

So this may explain why my new iPhone 15 Pro Max came at about 80%
charge in the box? Not knowing then what I know now, I immediately
connected it to the charger before setting it up.

Absolutely perfect. No problem at all.

CW: Keep the battery between 20% and 80%. Newest iPhone has an 80%
limit option. (Not sure why Apple didn't include the option for older
iPhones running iOS 17 ...).

You can also get apps and external charger to hold that on older versions

Unused phones: Store at about 50% (40%..69%).

Occasionally drain it to 0% solely to calibrate the charge level

Thanks for setting that straight, Jughead.

You can't calculate an accurate slope (percentage discharge as f(v)) w/o
both ends of the line. Discharge to 10% is quite adequate. And
discharge to 1% is slightly better (for accuracy).

Inadvertently I've discharged my iPhones to 0% over a dozen times. Yet
after 4 years of use, still at 90% battery "Max Capacity" per the Apple diagnostic.

And my iPad Mini has gone many dozens of times to 0% over 5 years and is
still going well. (older iOS - no mac cap indication).

Draining to 0% is killing the battery with absolut certainty. All Li-Ion accumulators.

You're confusing the % indication with absolute voltage. 0% ≠ 0V.

Draining below a certain voltage, can damage the batt (and even then can
be "recovered" with little long term damage with the correct chargers.

But Apple's "0%" point is (like most Li-ion charge controllers) set at a
slight margin above that voltage. Which, typically, for Li-ion is about
2.5V.

So most Li-ion battery __ charge controllers __ will open the circuit
(turn off the device) at 2.8V. And the % indicator is usually
indicating 0% at about 2.8V. And yes smartphones have charge controllers.

The rest (2.5V .. 2.8V) serves 2 purposes:

- safety margin
- discharge margin as the batt will continue to self-discharge below
2.8V ... this give some time to get battery to a charger (months if
there is no additional load.

You are knowledgeable about these things. FTFY

Yes, I know about these things quite well. Our company buys oodles of
Li-ion batteries every year for various products (18650 and similar
formats) as well as "system batteries" (proprietary cartridges of some
kind or another). So knowing the charge characteristic - and making
sure the employees do, saves us a bundle of cash yearly.
