sort of baffles me this site run by amateurs? first on the charging problem mine has a problem with the charger port , i have to pull the charging cable sideways to make contact because it was a bad port style decision on their part then there is no light to tell me if its charging . then theres the idea that changing the battery is as you call it easy yes easy if you plug a new one in but if soldering id involved that makes it a little harder for some people so you should not downplay that difficulty electronics are sensitive equipment remind people of that so they don't destroy their equipment.
