Exactly. I recently discovered that my iPhone on battery-saving mode is awesome, and now I put it on that mode even when its 100%, so it holds longer. Everything works fine. I havent found anything wrong. Apple should mak that mode the default mode. Battery-saving mode should be default on all things.

There are of course things like screen brightness or gaming performance that dont mix well with the above, but thats fine. Leave the brightness alone, and resume the battery-saving mode after the game is closed.

So basically, default mode should be battery-saving mode. Performance mode should be used automatically when a fame or something is running. And make a new battery-saving mode which is the default mode plus the low brightness, no games, no wifi, no whatever mode.

Am I missing something?

The default mode is already a battery-saving one, you can get an impression of a non-battery-saving mode by playing a game continuously, your battery will get run into the ground in 2~3h.

Low Power Mode is not about downclocking the phone and trying to sip power, it's about disabling a number of features which can already be disabled individually, but which (as far as Apple is concerned anyway) most users want/use:

* animated transitions

* automatic mail fetch

* Hey Siri

* background app refresh

* automatic downloads

* wifi association/roaming

* night shift

In essence, LPM makes the smartphone less smart to try and last a bit longer. If these are smarts you don't need, you could disable them all along.

It's also setting display brightness a bit down.

It does a lot more than lower brightness and cap clock speeds, it also disables night-shift and screws with all of the background process and predictive fetching, etc which the OS does.

I guess it does, since it saves so much power compared to running without the battery-saving mode. Still, I haven't noticed anything not working as expected, in my daily use.

You would get much of the benefit without a special mode by disabling background app refresh, location services and periodic mail fetch.
