Overnight Charging? My son got a new phone at Verizon tonight, and we were both warned against overnight charging...salesperson (who actually knew as much as I did for a change) said don't charge even my Q9 overnight. Battery debates have gone on for years. Lithium Ion batteries actually like to be topped off...or held at full charge...not like old batteries where memory effect was a concern. I can only guess that perhaps heat is the reason? Anyway...I've charged my Lithium Ion batteries overnight since they started being used, without issue. Appreciate you thoughts and comments. Thanks.
