You'll get the Unknown Part warning in Settings > Battery even if you use a Genuine Apple battery.

I think they now have made the iPhone SE 2020 do the same. Quoting the relevant section:

This is the current standard, and a good sign for future battery replacements, but unfortunately you’ll still get the “unknown part” warning. The only feature you’ll lose is Battery Health. Yes even if you’re using a perfectly genuine battery, Apple considers the repair “nongenuine” until they personally verify it.

Caveat: Apple will now let you pay for the privilege of verification, if you buy their part.

Caution: you'll get the Unknown Part message in Settings > Battery, even if you use a genuine part.

iFixIt has this documented at Apple can upgrade individual iPhone SE parts, can you?

@dontinw: 8Gb is 8 gigabit (how memory and flash manufacturers specify chip capacities). 8 bits to a byte, so 8Gb = 1GB (capital B). So 4 x 8Gb chips for a total of 4GB GDDR6 RAM.

My brother’s TC has the overheating issue. I think I’ll put in a Sunon instead of a Delta, because my personal experience is that a specialized manufacturer of fans will do a better job than a power supply maker who happens to shave a few pennies on a BOM by putting in shite fans. Also, these guys say the Sunon fans use alien technology.
