Q: I was told that the battery in my iPad doesn’t have problems with memory effect. Is this true?
A: It is true. Memory effect, where (short explanation) a battery doesn’t fully charge because it hasn’t been fully discharged does not affect lithium-ion polymer batteries, the type of battery used in iPads, iPhones, and iPods.
When charged lithium-ion polymer batteries charge to 80% fairly quickly, then “trickle” charge slowly for the remaining 20%. This fast recharge is a big benefit to musicians who may need to grab their trusty iPad any time inspiration strikes.
