Hijacking the thread, I have a question about the battery in my mobile phon=
e. I'm careful about charging, and want to get as many useful years of life=
 as possible out of the battery. I try to never let the battery get too low=
, never charge the phone if it's hot, and never let it charge fully. Based =
on the phone's gauge, I charge it when it's down to 40% and take it off cha=
rge when it reaches 80 or 85%. I think this is probably a pretty good way o=
f doing it. I plug the charger into a timer so I don't have to watch it, I'=
m not totally OCD :)

My question regards preferred charging current. The charger that came with =
the phone will do my normal charge regime in about 20 minutes. The good qua=
lity charger from a previous phone will take 90 minutes to do the same thin=
g. Neither charger noticeably heats the phone.

Which is easier on the battery, high current for a short period of time, or=
 medium current for a longer time, both taking the battery from 40% to 80% =
state of charge?

Thanks, Bob
