Smartphone Battery Usage
7 Answers
Morning!
I have a Samsung smartphone, about one year old. The battery life is impressive but it always seems to need charging when I need to take it out with me. Is it definitely, DEFINITELY OK to charge it overnight every night without affecting the battery's capacity to hold a charge? I realise that I may be living in the past in this matter but I don't want to get it wrong.
Thanks techsperts (see what I did there?)

The confusion is caused because old battery technologies (pre Li-Ion) did have memory so needed to be discharged fully before recharge.
Li-Ion have little or no memory issues and are actually enhanced in terms of maximum discharge/charge cycles possible if they come on-charge from a shallow discharge (say 70% left). So regular recharging, little and often actually helps.
A secondary issue was that charging did not stop adequately when the battery was fully charged. This knackers Li-Ion batteries because they get heated up, indeed most types suffer if overcharged. This has been solved by modern control circuitry.
