[Lex Computer & Tech Group/LCTG] keeping cell phones charged

[Michael Alexander]

Thanks, John.  Will try the Komando phone charging recommendation.

A couple of weeks ago I read an article that purported to explain why keeping Lithium-ion batteries fully charged is bad for battery life (it’s consistent with Komando’s recommendation):     At 100% charge, the battery anode has to expand to accommodate the Li+ ions; repeated full charging causes mechanical wear and tear on the anode.  
All plausible, but if so, it makes one wonder why manufacturers don’t design chargers to stop before “fully” charging and discharging.  Maybe they want to boast that their phone’s charge supplies the device for longer than other manufacturers’ phones?  (I don’t want to entertain the $ hypothesis that they just want to sell replacement batteries or inspire consumers to decide it’s time to jump to the latest model.)

The "best practice" seems to keep changing
