The Li-Ion battery has 4 stages of charging :the initial trickle-charging to bring battery to Pre-charge stage, then constant current charging, then constant voltage charging(its like floating....right?) & final stage Top-up charge" . Can anyone reply with the stages of charging for Li-Polymer ( iPhone use Li-Polymer), or suggest some link which explains about Li-polymer charging details.

  • It's better to put some detail in your answer rather than just a link so it's useful if the link goes dead, even if you just say it makes no difference to the charger and give the link as a reference. – PeterJ Jul 11 '13 at 07:52
