My question is if lithium-ion batteries just lose capacity over time or if they also become more wasteful. From a practical perspective, can you easily get around loss of capacity in older batteries/devices by just carrying a powerpack or would an older battery also use up more power in a certain amount of time, thus draining the powerpack faster?
Understanding why batteries lose capacity. It was revealed that hydrogen molecules from the battery''s electrolyte migrate to the cathode, displacing the lithium ions. This reduces the available binding sites for lithium ions, which

Given the nature of how these batteries work, loose lithium-ion battery cells present a particular danger. The exposed metal positive and negative terminals have more potential risk than you find with NiMH or alkaline cells. Short circuit the terminals and they create a rather sudden and violent discharge.
It started losing power too quickly when fully charged (and just out of warranty) so we bought new batteries. These were fine for a few months then the same thing started to happen - I''d get about a mile out of the scooter before it started to lose power, and limp home on one red light. I took the new batteries back to the shop and explained

Lithium does not like or need to be kept at high voltage for a long time. There is no need to keep the Lithium batteries on the charger because they do not lose their charge as quickly as Lead acid batteries If you have other loads you want to run, just let shore power provide that power and disconnect the Lithium batteries.

This shortens a battery’s life expectancy. For decades, researchers have assumed that self-discharge in lithium-ion batteries is caused by the movement of lithium ions, but the new research finds compelling evidence that hydrogen, not lithium, is the true culprit.
In a typical lithium-ion battery, lithium ions, which carry charges, move from one side of the battery, called the anode, to the other side, called the cathode, through a medium called an electrolyte. During this process, the flow of these charged ions forms an electric current that powers electronic devices.
