I don’t believe you’re correct. Small discharge cycles are not at all bad for the battery.

Similar to a mechanical device that wears out faster with heavy use, the depth of discharge (DoD) determines the cycle count of the battery. The smaller the discharge (low DoD), the longer the battery will last. If at all possible, avoid full discharges and charge the battery more often between uses. Partial discharge on Li-ion is fine. There is no memory and the battery does not need periodic full discharge cycles to prolong life. The exception may be a periodic calibration of the fuel gauge on a smart battery or intelligent device.
If you look at figure 6, cycling from 75-65% was better than 75-25%.

You’re thinking of keeping the battery constantly charged at an elevated voltage, eg 90-100%. There’s nothing wrong with many small cycles. The most optimal way to use a lithium ion would be many charge cycles and the battery constantly going from 49-51%.








See my comment above with the battery university link, small depth of charge/discharge and frequent cycling is optimal for lithium ion batteries. The longest longevity was many 75-65% cycles, followed by 75-25%, then 85-25%, and lastly 100-25%. There’s nothing wrong with small cycles on lithium ion batteries.
