Actually I think this is a myth and very widely debated. IMO Lithium ION batteries should not be discharged unless under best effort battery troubleshooting.
I would start more locally, and monitor your use trends plus programs installed and look for patterns there.
A few widely accepted rules:
- Like many rechargeable batteries, lithium-ion batteries should be charged early and often. However, if they are not used for a long time, they should be brought to a charge level of around 40%–60%
- Lithium-ion batteries should not be frequently fully discharged and recharged ("deep-cycled"), but this may be necessary after about every 30th recharge to recalibrate any electronic charge monitor (e.g. a battery meter). This allows the monitoring electronics to more accurately estimate battery charge.[27] This has nothing to do with the memory effect.
- Li-ion batteries should never be depleted to below their minimum voltage, 2.4 V to 3.0 V per cell.
- Li-ion batteries should be kept cool. Ideally they are stored in a refrigerator. Aging will take its toll much faster at high temperatures. The high temperatures found in cars cause lithium-ion batteries to degrade rapidly.
- Li-ion batteries should not be frozen [50] (most lithium-ion battery electrolytes freeze at approximately −40 °C; however, this is much colder than the lowest temperature reached by household freezers).
- Li-ion batteries should be bought only when needed, because the aging process begins as soon as the battery is manufactured.[27]
