Questions about battery

[bj097]

Some conceptual questions:

If bluetooth is turned ON in iPhone setting but NO bluetooth device nearby, does it also eat battery as greatly or nearly as greatly as when bluetooth device is connected?

Same questions for WiFi and location services, if WiFi is enabled, but not connected to any hotspot, and if location services is enabled, but not being requested by any apps.

Does connected through WiFi kill battery faster or through cellular data?

Do I need to turn off WiFi if connected through cellular network and vice versa to save battery?

Do I need to manually kill the background apps to save battery?

Use your phone as needed and don't over think it. If it needs to be charged, charge it. I never turn off anything you've listed and have no excessive battery drain. If you do it's more likely a rogue app or some other process is running abnormally in the background

Unconnected Bluetooth On uses insignificant power. You can leave it on perpetually and you’ll never notice a difference.
Most Bluetooth devices disconnect from the iPhone the moment you leave the app, so it’s not a battery drainer.
I have one Bluetooth smart plug that holds on to the iPhone if the app hasn’t been quit and won’t let another iPhone connect. I’m not sure it’s using significant power either.

The Wi-Fi radio may be a different story. It’s much more powerful and can use more power, but honestly, I haven’t been able to tell one way or the other if it’s on or off for years.

Does airpods eat battery fast? I'm thinking about getting it but worried that it will kill battery fast. I don't like to bring portable battery so battery length is my consideration.
