While we're happy to note that the adhesive inside the charging case battery is not too stubborn, and there's no heat required to remove it ...

... all the same, we're wary of all these repair-complicating soldered connections. Keeping internal connections secure is a concern in any wearable for sure, but we've seen competitors accomplish the same with a lot more modularity.

The rated voltage of the case battery is 3.85 V at 570 mAh and 2.194 Wh. That's about 0.1 Wh more than the dual-cell battery in the AirPod Pro charging case, and a lot more than the 1.03 Wh Galaxy Bud case has to offer.
