Most Lithium-Ion batteries are quoted as lasting 400 charge cycles not 1000 charges. A charge cycle is defined as charging the battery from 0% to 100% then discharging it back to 0%. After that 400 or so charges then you'll expect only about 80% capacity of the original battery, losing 20%, ultimately not lasting as long as it previously did. Every Lithium-ion battery has these whether it's a Kindle battery or an iPhone or Laptop battery.

Charging under regular use (topping up) does not count as a charge cycle or even a significant part of a charge cycle.
The website The Battery University has been around for years and is commonly given as a reference in battery matters. They have a very good reputation for reliability. Here's a link to one of their many articles about lithium ion batteries:

I think you'll find it useful reading.
