m1 air battery capacity declining

My friend is facing an issue of Battery capacity declining. He is not a nerd, but I am trying to helping him out.

In coconutbattery its showing 98.4% maximum capacity over hardly 10 cycles while in system report it shows 100% capacity.

Please answers if you have researched or have find some solutions.

  1. Is coconut battery accurate than system report?
  2. Is it good if macbook get charged all the time? (to reduce cycle)
  3. the USB-C monitor charges the macbook slowly means the battery get reduce very slow. is it a good practice?
  4. I have heard if your battery reach 80% capacity before the warrenty expires, you will get free battery replacement. is it true in India?
  5. Even after at 80% capacity, how many hours we can use the laptop?

No need to answer all the questions. Please use sequence number

Here I am attaching 2 images of coconutbatter report and system battery report
