How is a milliamp-hour rating of a battery useful to an end user? Without going very deep into details of the device's average and peak power consumption under different usage scenarios, it's very difficult to correlate that measure of capacity to practical battery life.
lets take weigth out of all food packaging too! nobody is a damn nutritionist either!
...the length those fanboy go. sigh. Go on defendind the indefensible and gate keeping your so precious superior technical knowledge that the common man is incapable to grasp!
I'm relatively technical and I have no practical idea of what (for example) 400 mAh means for a phone. It's not that I don't get the technical definition, it's that without any context 400 mAh is just a number. Even if I were to look it up, how do I know that my understanding won't be off in a couple of years if power consumption requirements for phones change?
On the other hand, if you tell me that my phone's battery can handle around 7 hours of streaming music, or 12 on standby, I know exactly how what that means for my practical usage habits.
I imagine the average phone user's attitude is somewhat similar to mine.
