To drain or not to drain? A New York Times reporter takes on Verizon over a dead cell phone battery and how it was caused. Not satisfied with Verizon's response that her battery was "overcharged" due to overnight charging, she set out to prove them wrong.
The answers she found?...
1) A battery cannot be overcharged, once it is full the power is cut off.
2) It's better to not let your battery get too low, because it cannot handle the strain and will inevitably shorten its life. So after half-empty (or half-full?) plug it in.
Do you buy it? We're a bit skeptical, we've heard too many urban myths about how to extend the life of our laptop batteries and they keep dying on us. The bottom line, in our opinion, is that batteries are just one finicky bunch.
