When did these changes take place?

Given the size of the case, you would hope that the Truengine 2s have a significant reserve charge, and you wouldn’t be disappointed. According to SoundPEATS, the case holds 30-hours of reserve charge. I didn’t have time to test this fully, but since the initial charge when I first received the earphones for review nearly two weeks ago, I haven’t had to charge it.
