jiya eMMC 5.x HEALTH report:
Device lifetime: Normal
Estimation of the device lifetime (SLC): 0% - 10% device life time used
Estimation of the device lifetime (MLC): 0% - 10% device life time used

Device Health Report features in eMMC ext_csd rev.1.7 (eMMC 5.0 and above) provides nand flash program/erase cycles information in percentage of useful flash life span.

Please take a look at the data table below to view eMMC health information by Device life time estimation value and Pre eol info value.

Now we can conclude, to know the health information of an eMMC 5.0 we use the above two indicators.
That is :

OK(Health) IC Chip
Device life time estimation value = 0-50%
Pre eol info value = Normal

BAD IC Chip
Device life time estimation value = above 90%-Exceeded
Pre eol info value = Urgent

Hope this little info useful for you
