TIL it's better to charge a little every day than let your battery get low before recharging. (www.youtube.com)

From "Engineering Explained." He says that as you charge/discharge, the random orientation of microcrystalline structure in the battery combined with expansion/contraction due to Lithium migration results in forming cracks in the particles, which then results in reduced battery capacity. I've been letting my battery get down to 50% or so before bothering to charge back up to 80%, I may default to 70% and charge after every trip instead. (For a Volvo with NMC chemistry I'm not sure if I have "high nickel content" and would benefit form staying below 75% or not.)

What many people don't seem to get is that the phone will lie to you for your own benefit, reporting 100% full when it is actually 75-80%, and adapting that as the battery ages. So you usually don't need to do this manually.
