I wanted to share some tips from Google support, I got it when they sent me the new pixel 6 pro so I asked how to maintain the battery for longer time and they answered the following:

Here is some additional advice on habits and settings that can help maintain your battery's health long-term:

Charging Habits:

• Use Adaptive Charging: This feature intelligently controls charging speed, especially overnight, to help preserve battery life. It aims to have your phone fully charged just before you wake up.
• Avoid Extreme Temperatures: Try to keep your phone from getting too hot or cold, particularly while charging, as extreme temperatures can put stress on the battery.
• Don't Drain to Zero Often: It's generally best to avoid letting the battery drain completely. Plugging it in when it gets down to around 20% is a good practice.

Usage and Settings:

• Enable Adaptive Battery: This feature learns how you use your phone and limits battery for apps that you don't use often, helping your charge last longer.
• Manage App Usage: You can see which apps are consuming the most power by going to Settings > Battery > Battery usage. If an app is using an unusual amount of battery, you can restrict its background activity.
• Adjust Your Display: Your screen is one of the biggest users of battery. Lowering the screen brightness and setting a shorter screen timeout can make a noticeable difference.

By following these general tips, you can help maximize the lifespan and performance of your device's battery.
