Will it make a difference if I'm watching (MP4) 1280 resolution ~1GB on my iPhone vs 480 resolution ~400mb file? Does the quality of the video affect how fast the battery drains?
Let me ask you this. Will your car's gas be affected based on how fast you accelerate? Well, im guessing the iPhone's battery cell works the same way. The more the phone has to push, the more taxing on the battery it will be.
