I cannot imagine they want to risk a Samsung type incident, where tight construction tolerances are essentially non-starters with Li ion batteries, which swell with charging (due to different crystal lattices of the anode associated with the embedded lithium ions). The issue is that more recent advances in battery tech make this swelling worse. What this means is that it might be a while before battery capacity begins to noticeably increase again, and engineering focuses might be more on lowering energy consumption to improve off-cord work time.

I do wonder whether the improvement of battery tech will be sufficiently fast to beat the development of wireless charging tech, which may serve as an incentive to reduce the size of the battery.
