It's good that the charging circuit switches over to trickle before 100%, overcharging is very hard on a battery. Even float (trickle) charging is undesirable. Batteries are most stable around 62% charge. So ideally, you'd only charge them from perhaps 30% to 65%. But we routinely charge to 100% because we usually want the extended run time.

If you want to extend your batteries lifetime keep it away from extreme heat and try to avoid charging extremes. That is don't run it down to zero if you can charge it at 20 or 30% instead. And it helps a bit if you pull the charger at 95% rather than let it go to 100%.
I've been using ereaders for years and this was really helpful. Just shows you can always learn something new. Thankyou.
