Give me battery life or give me death, all the other specs have advanced to a point that this is the only thing that really matters now besides price for any midrange or high end 2015 or new cellphone.
Yes I want so way of "not thinking charging" which is the difference between wireless charging and usb charging. But total battery life is the most important. I want a battery life that can last 2 real days so we are talking 20 to 30 hours.
What is the difference between wireless and usb charging, you may ask?
One requires you to dedicate enough attention to grab a small cable, and to plug it in small hole which requires a precise alignment of the parts, aka attention to detail. Wireless charging by contrast is just placing it on a mat.
This may seem like a no big deal and it is no big deal when that is the only thing you need to do at that moment. But add distractions, add disrupted routines, add other things you need to focus on at that very moment, add you are in the zone thinking and thus you are your own distraction and all this translates into not remembering to plug in your phone.
With conscious higher order thought can only do 1 thing at a time. It can "fast task" dozens of things per second but this is still only do 1 thing at a time. Using your eyes to place something in a precise spot, and to align a connector into a hole requires the conscious higher order thought part of the brain. An area in the frontal lobe called the FEF (frontal eye fields), an area in the back of the brain called the IPS (intraparietal sulcus), and to a lesser extent other brain areas such as the SEF (secondary eye fields) plus numerous subcortical structures such as the Basal Ganglia, Cerebellum, etc.
And each time you shift attention from 1 subject to a completely different subject there is a cognitive cost. You are more likely to make a mistake and forget some important detail, or get distracted from your list of important goals.
By contrast wireless charging does not need all that fine motor detail, and it can become an automatic algorithm which does not need the higher order brain areas. Your brain enters a room that you are familiar with, and it just places the phone on the mat while doing something else with your eyes and your hands, people call this implicit cognition, or automatic thinking, or unconscious decision making. Why because the tasks is so simple your brain can make it into a little subroutine and dedicate small little brain areas just to that task. While higher order cognitive thinking has no such thing as multitasking, only fast tasking, automatic thinking is capable of multitasking for each of these smaller dedicated brain areas only have to work on that task it is self contained and it can be run in parallel with other similar subroutines.
Effectively to use a computer analogy your higher order brain is a Single Core CPU without hyperthreading. One thing at a time, but it has cache and ram to store multiple algorithms, and it can switch tasks but still can only do 1 thing at a time in its pipeline. The implicit or automatic brain is instead dedicating specific hardware for routine tasks, things like ASIC (application specific integrated circuit), FPGA (Field Programmable Gate Array), various forms of hardware decoders and encoders such as video and audio, all of this designed to take types of mental loads off the higher order mainline cpu.
Thus wireless charging is very important for a phone, or something similar which create a system of you automatically recharging the battery without thinking about it. The battery should always be full and if your unconscious habits will make the phone be always full more often that is a very good thing.
But another solution is just give a big enough battery that even if your day goes to hell, you still have 1 more day charge, and hopefully you will remember to plug it in before the 2nd day is up.
