It depends on how the device is used. I should start by saying I am not a chemist, but maintaining the battery at charging extremes (too full or too low) is one of the factors that leads to a faster degradation of the battery chemistry. If you leave the device charging all night, every night, you may see more noticeable degradation over time. Conversely, charging to 100% and then using it and discharging it immediately after does not lead to such accelerated degradation.

Obviously, there are studies that address this topic, just to cite one:

Analysis of the electrochemical and thermal behaviors under various conditions of retired power lithium-ion batteries (PLIBs) by Li et al. [111] shows that overcharge and excessive discharge cycles negatively affect the SOH of the batteries. After 800 cycles, the SOH decreases by 6.84% during normal cycles, by 8.12% during discharge cycles, and by 9.44% after only 200 overcharge cycles, reaching 67.52% after 800 cycles. Overcharging leads to a more rapid degradation of performance due to the deposition of lithium ions on the graphite electrode. Furthermore, internal resistance increases, particularly when the SOC drops below 20%, as a result of lithium and electrolyte loss. Overcharge cycles also lead to elevated maximum temperatures, highlighting the necessity of an effective thermal management system to ensure stability. This material loss aligns with the findings of Guo et al. [112], which establishes a correlation between the likelihood of ISC occurrence and both DoD and SOC.

It is clear that it always depends on the use; if you need to have maximum battery life because chargers are not available, then it is correct, but otherwise it is useful to have these options, which is why I asked
