actually, no, I'm not. Resorting to insults doesn't really prove your point. I do, indeed, know how to charge a LiOn battery.
Here's the steps outlined by iFixit:
"... eject the SIM tray, heat up the battery door, draw off the battery door with a suction cup, then separate the door with a case-opening tool, then undo 13 screws, heat up the LCD assembly, pry open the charging chip flex ribbons, pull off the front-facing camera connector, battery connector, ear speaker connector, remove the entire motherboard, then pry off the battery with a spudger tool."
That doesn't sound like "pop out the battery and drop in the replacement" to me. The S3 and the S5 -- which I have personally replace the battery on -- are truly replaceable. Indeed, I owned the S3 for 3 years and replaced the battery once. I don't consider that LiOn abuse, frankly.
