The heavy core block takes 35 seconds longer to break compared to Java's counterpart with your hand. This means it takes significantly longer to mine.
Steps to Reproduce
Place down a heavy core
Switch to survival mode
Break it with your hand and use a stopwatch to see how long it would take to break
Repeat the same steps on Java
Compare it
Observed Result
The heavy core took 50 seconds to break on Bedrock, which is 35 seconds longer than Java does.
Expected Result
The heavy core should take the same 15 seconds to break on Bedrock, in parity with Java.

I can confirm, Which seems not match the mining speed on normal hand

This issue seems to be resolved. I tested mining a heavy core with a netherite pickaxe in Bedrock Edition Preview version 1.21.0.26 and Java Edition version 1.21 Pre-Release 2, and both mined in the exact same time.
Edit: Misunderstood that the issue affected specifically mining by hand, my bad 🙂Â

@unknown, its summary is probably a bit misleading, but this issue is about breaking heavy core with your hand or incorrect tools, not with pickaxes.
Still an issue in 1.21.10.21.

Note this is fixed in 1.21.50.20

In my testing, heavy core takes 15 seconds to mine in Java Edition. However, I can still confirm that Bedrock Edition takes 50 seconds to mine.
Relates to MC-270322 (which is no longer a parity issue).
