I bought my MBP with the M2 Pro chip in March 2023 and the battery health has been reducing drastically,
I have a cycle count of 80 and a battery health of 88%. The BH seems to reduce by a percent after every 2 weeks and I am quite concerned. I understand the batteries deteriorate with time, but this is quite concerning on my part.
I mostly use the laptop plugged in and connected to two 4K monitors, after I realised the BH was reducing very fast, I started using it on battery between 80 - 30% then I charge and that still did not make any difference.
Any suggestion as to how best I use the laptop to prevent the battery from deteriorating?
I also have optimize battery turned on

If you are using external monitor(s) leave it plugged in— this would be highly recommended. There is no need to try and outsmart the Battery Health Management software
personally I do not worry about the battery— when it needs replacing, replaced it you can spend all day being "quite concerned"
Please note: Apple will not entertain a battery issue until it drops to 80% health or the battery is showing signs of swelling.
as you indicate plugged in is good
The rule of thumb—if you are near the mains leave it plugged in, if you need the portability then run on the battery only—this is how you optimize your battery charging and extend the working life of your battery by reducing the cycle count.
It is not necessarily a linear progression until its death...
BHM has been known to increase health over time:
