Link: Overcharging the iPad ☍

Shared on March 26, 2012

TUAW’s Chris Rawson looks at some of the claims about the iPad charging past 100%:

Where Dr. Soneira’s analysis and CNBC’s reporting on the issue both go off the rails is when they both say that the iPad is actually overcharging its own battery and thereby causing damage to it. CNBC’s analogy is that a battery is like a glass of fruit juice: it’s meant to be filled to below the “rim,” and if you overfill the glass the juice can spill out. This is an insipid analogy that demonstrates ignorance of how lithium battery technology has worked since… oh, the mid-1990s or so.
