Will frequent charging shorten battery life?

Question

I purchased a Nokia Wireless Charging Plate DT-900 for my Nokia Lumia 920.

If I place my Lumia on the charging plate all night every night and every time I put it down not using it, even if the battery still has most of it's charge (e.g. 80% or more), will this do anything to shorten the battery life?

I know some types of batteries for other tech items only accept a certain number of recharges. So I'm wondering if using the plate all the time is not recommended and if I should put my phone on the plate or otherwise charge my phone only when the battery is low.

Answer 1

Some people say that it is better to charge the battery of any mobile device after it is fully drained. But, this is applicable to nickel cadmium types and when it comes to lithium ion, it is not necessary to fully discharge the battery before charging it. This is because when the charge reduces too much, it might cause damage to the device.

Lithium ion batteries (The kind used in all modern cell phones) do have lifetime rating in charge cycles, but you do not "use up" a charge cycle by charging too early, merely the portion of a charge cycle. Like the article states, li-on batteries are pretty durable as long as you keep them cool and prevent over-drainage.
