Hi AJL,

Does your setting look something like this on my free Samsung phone?
<https://i.postimg.cc/VL6HGPGc/battery01.jpg> Android Battery Settings

My el cheapo (actually free) Samsung came with a fast charger and a modern
5 amp hour battery, which, if you compare to today's laughably puny iPhone
batteries, means Apple needs this setting more than we do.

*The iPhone owner should be _embarrassed_ about their baby batteries*

If you lose, as is often documented, 20% of your capacity after 500 cycles,
then 20% of the laughably puny iPhone baby batteries drops them way below
threshold far sooner than 20% of the huge modern Android batteries does.

*Apple designed the iPhone baby batteries to die _sooner_ than Android*

It's plain jane physics why iPhone batteries fail sooner than Androids.

Again:

Battery SIZE doesn't matter—matter LIFE matters.

Thank you for checking that information out.

My (admittedly free) Android is the cheapest Galaxy made, I think, which is
far more powerful in terms of functionality than any iPhone ever sold, but
it doesn't do wireless charging, so that may be why you have what I don't.

Bummer. My Android is the bottom of the line for Samsung Galaxy devices so
I'd be surprised if it has anything special over the better Galaxy phones.

BTW, I noticed more battery performance options scattered about in the
settings. For example, do you have Developer options turned on perchance?
<https://i.postimg.cc/3N8zZ1vt/devopt05.jpg> Turning Developer Options on

In my Developer options there is a switch for "Wi-Fi scan throttling" which
says "Saves battery and improves network performance" by reducing the
frequency in which the Wi-Fi radios will scan for new access points.

There's also a setting for "Background process limit" and "Don't keep
activities" which will "Destroy every activity as soon as the user leaves
it" in addition to the ability to view and control all running services.

Luckily the battery is so huge it could jumpstart a car, but still, it's
nice to have all these battery options, and the apps that keep track.

Here, for example, are a few screenshots of what the GSAM app displays.

And here's just a few of the BBS options for keeping tabs on the battery.

We should probably just open a separate thread on the Android newsgroup
for what options exist to manage the battery, since there are so many.

No I don't have Developer options turned on. I hadn't planned to keep
the Galaxy S10+ this long so didn't worry about the battery other than
the heat thing which I figured may be bad for other phone parts as well.
Since I've seen no battery degradation (for my light use) after 3 1/2
years I'm not going to change things at this late date since I see a new
phone peeking at me just over the horizon...

BTW the wife's iPhone's battery seems to still work just fine after 2
years (the Verizon payments just stopped). I can tell because she's
hours on it most days gabbing with the kids and grandkids. And her
wireless charger isn't modified like mine so maybe I did waste my time...

Oh. I see. Well, it's the first thing I turn on in any Android but I
recently saw a thread that shows you can recover from a shattered screen
even without it (although not as easily as you can if you turned it on).

What Developer options allows you to do is neat stuff like GPS spoofing,
and Wi-Fi MAC address randomization for every connection and mirroring your
phone onto Android over Wi-Fi, and keeping the phone awake during charging
(if you like that) and verbose Wi-Fi signal strength logging and faster
and/or more reliable switching between Wi-Fi and cellular data (for fewer
dropped calls in low signal strength areas like mine) and just about a
billion other things (like choosing your default codecs or frequencies).

There's more about it in this thread:

The battery on that S10+ is surprisingly Apple sized, and that's a very
small apple when I say that, at only a puny 4,100mAh which is small
compared to most Android batteries today (it's about on par for Apple but
Apple designs the phone to die sooner than Android as a result).

Since your battery is appreciably smaller than mine (at 5 amp hours), I
would think you need the 85% charging limit more than most of us do.

The reasoning is that you lose about 20% (or so) of your total capacity
after 500 cycles where a loss of 20% of 4.1 AH gets you down to 3,280 mAH,
while a loss of 20% on a 5AH battery keeps it at 122% of that at 4000 mAH.

Stated simply, the smaller battery will always die sooner in all ways.
(There's nothing good to say about a small battery in terms of life.)

But if it's already old, then you're doing the right thing as your total
cost of ownership goes down down down every month you hang on to the phone.

No argument with you there, as with today's fast chargers, you're up and
running nowadays in an hour or two even from a completely smacked battery.

Good to know. My iPads are feeling weary especially when it gets cold.

They get flaky but the batteries are still holding up a lot better than the
iPhones of the same era that had to be secretly throttled so that Apple
could sell more iPhones.

Funny that Apple's special battery chemistry was only put in the iPads. :)
