This maxx has a charging problem. I have changed 2 batteries because of this. If I let the phone get to somewhere in the less than 10 percent battery life the phone does not like to charge. Last night I messed up and let it go to 0. When this happens I get the battery picture with a ? Mark in it and it will not charge. I take the back cover off of the phone and for some reason it usually starts charging. I let it get back to 30 or 40 percent put the cover back on and all is well until I mess up and let it get to low again. Anybody else experience any goofy problems like this. PS... All kinds of chargers. The same thing.
