Some time ago, I stumbled upon a graph (sorry unable to retrieve its URL) showing correlation between the discharge depth of a battery and its lifetime in cycles.
Obviously, the less you discharge it, the longer it'll last.
OTOH, the less you discharge it, the more you'll cycle it.
From data scraped from the graph, despite all of this is not linear, I found the best compromise was to not go lower than 50 % discharge.
I've been applying this discipline to my new notebook battery for 6 months and its full capacity is now at 95 % after almost daily use.
And 3% on the lost 5% were after I ONLY ONCE let it go to full discharge.
- aeries 8y agoIt had probably already lost the 3% but now realized it after your unintentional "calibration".
- jws 8y agoAnd 3% on the lost 5% were after I ONLY ONCE let it go to full discharge. It is probable that what you saw was your capacity gauge calibrating to the actual capacity of the battery. The device doesn’t actually know its capacity until it hits empty.
- solarkraft 8y ago> OTOH, the less you discharge it, the more you'll cycle it While by some accounting it may be more cycling (although I think most count total energy in/out for cycles), it is much easier on the batteries. They are pretty robust in the midle regions.
- dschuler 8y agoI believe a cycle is considered a cumulative discharge/charge of 100%, so discharging to 50% twice and back to 100% is one cycle.
- Wowfunhappy 8y agoIf you never let the battery go past 50%, then what use is your healthy, high capacity battery? Might as well have one that can only hold 50% of it's charge.
