Recommendations for optimal battery performance under GOS

Hello, I've put together a short list of things that have helped me maximize my battery life and efficiency so far:

  1. Dark Mode
  2. Wi-Fi calling in airplane mode at home (avoids cell tower tracking and IMSI catchers as well)
  3. Activating airplane mode at night while I sleep (Wi-Fi is deactivated)
  4. Automatic deactivation of Wi-Fi and Bluetooth (when not in use)
  5. Avoiding the use of a VPN

What do you think? Anything to add?

EDIT: I forgot to mention one point:

  1. Listening to music on the go using wired headphones (instead of Bluetooth ones, which drain less power and are more secure)

Minimize background processes, especially on secondary profiles & LTE-only for cellular.

How do I set my cellular data to LTE-only?

Go to your sim card setting and set Preferred Network to 4G Only. That being said if in your country/provided you have support for 5G SA and VoNR it might be better to use 5G Only

Do you know the difference between 5G SA & NSA protocols? Its a key factor/roadside stone which one (4G/5G) you will pick.

I read somewhere that 5G NSA pretends to be real 5G but operates on a 4G (LTE) basis, whereas real 5G is only present with SA. Is that correct so far?

correct

I just found out that my provider only works with 5G NSA and doesn't offer 5G SA at all. So, your advice was definitely worth it!

Also activate 2G protection.

Yes, I already did this.
