The happy range for a modern battery is 20-80%.

The bottom and top 20% are what's causing the wear, so merely staying between 90% and 100% won't do you any good.

Source? If you are letting charge drop in that range and charge again, you are creating charging cycles. Charge cycles reduce the capacity of Li-Ion batteries.
