Comment 2 for bug 528543

@lavinog - I agree on your assertion that it is counterintuitive to keep a battery at low capacity for a portable device. Which is why I think having "profiles" is a good alternative.

By default, let it operate as it is doing now - charge always. However, a lot of people use their laptops as desktop replacements and it makes sense for them to choose a "optimize battery lifespan - battery will not be fully charged" option.

As I have read on many sites, even charging batteries only when they fall below 90% is far better than continuous charging. A 90% charge is still a very acceptable number for portable devices.

Profile-based battery charging gives one the flexibility to tune your system to maximize battery lifespan.
