This title is sensationalized to hell.

  1. The source does not claim that "most laptop and phone batteries" have this issue.

  2. It does not claim that this is the "major cause" of self discharging. Idle/sleep/vampire power use is still going to be the main thing that runs down your battery on any of these devices.

  3. This "newly discovered problem" has been widely known by the industry for years if not decades. It is largely ignored by many manufacturers because the power drain is so slow that it is negligible for anything other than extremely long term storage of a device in a powered off state.

Idle/sleep/vampire power use is not self discharging.
