What MG is doing here is that to err on the side of caution, they decrement the SoH value by 0.01 every day irrespective of the battery health.
But they also do a real measurement of health when the car is charged on AC from a low SoC to 100%. Personally I have seen my SoH jump from 95% to 97% and this has been replicated on many ZS EVs.
I know of folks with 60k KMs ODO and car age of 2.5 years to have 98%+ SoH because of this. So nothing to worry and I believe MG is doing the right thing here from a tech perspective.
Tesla also has a similar problem and they recently introduced an option to do deep discharge and calculate health via software. Maybe MG can do something like that
The SoH on LFP batteries are hard to compute.

So I have emailed them regarding this before even reading this blog.
Since then no replies have been received so far.
