Here's a list of things I do to prolong the life of my iPhone battery.

1. Keep the display dark mode
2. Never let the battery drop below 25%
3. Keep the phone cool never leave it in a hot environment.
4. Kill all the apps that are running in the background.
5. Turn location services off. (Mind you this will effect apps that need that function: Maps)
6. Turn off Bluetooth, Airdrop. Also turn Cellular data off when you're in your home network and remember to turn cellular data back on when you travel and turn the WiFi off.

These are just some of the things that I do to prolong the life of my battery on my iPhone 11.

Suggestions are welcome here, but some you listed have zero impact on Battery Life/Health on iPhone 11, such as:

• Dark Mode
• Swipe away Apps that are running in the background.
• Turn off Bluetooth and AirDrop.

Cheers,

• The Bluetooth module uses very little, unnoticeably little, battery.
• Apple has said that Swiping away Apps has zero effect.
• iPhone 11 has an LCD display. For dark or light mode, the entire display must be lit anyway, so it makes no difference. On an OLED iPhone, Dark Mode might help battery life, but not health.

So having the bluetooth receiver/transmitter turned off along with killing apps that are using cpu power to function along with powering down the display has no effect?
