I bought my phone at a sprint store in the mall sometime in late January 2011 and they had it shipped into the store brand new (dont have exact purchase date but it was definitely in late January of 2011)
I've had a screen protector and an Otterbox Commuter case (i think it's either the commuter or the defender .. it's the one that has a thick gel case that goes on 1st, and then a hard shock absorbing plastic case overtop of the gel case for double protection.. everyone knows the quality behind the otterbox cases -- I got it on sale from amazon.com for around $35 i think they sell for over $50 on the otterbox website though)
So i take EXTREMELY good care of my phone, i got the case in the mail before i even purchased the phone, and i put my screen cover and case on before i even turned my phone on in the store..
I've had my EVO going on around 5 months now, and my charger port is just now beginning to be 'loose' inside the phone, and when i use the Micro USB charging cable the charge and connection cuts in/out. and the light constantly flickers. This is 100% not due to customer fault or damage, as i treat my phone like a hemophiliac premature infant baby holding a Faberge egg.
I believe that the reason the port becomes loose is due to the EXTREMELY short battery life, which in turn causes a non-stop all day plugging and unplugging of the charger into the phone, and i figure that i plug the charger in, and pull it out on average 10+ times a day .. and if i'm sittin at my computer and transfering files to and from, and also using my phone for calls i'll plug and unplug my phone upwards of 30 times a day easily. Multiply that by 5 months (5 x 30 x (15 plugs on average a day) ) = over 2,000 times i've probably plugged and unplugged the little micro usb tip into the little micro usb port, and each time a little tug and pull and fan angling it into that little hole causes it to be moved and pushed and what not over and over and over again, OF COURSE it's going to eventually become loose, and once it becomes loose.. OF COURSE it's going to cut out and short when you try to charge it because it's LOOSE!
IS THIS FAULT OF THE USER? I DO NOT THINK SO
IS THIS FAULT OF HTC ? I can't really blame them either... it's just fact of life, unless they decide to use a stainless steel charge port and have a rod-iron chassis for that charging port to connect into so that it doesn't ever get loose or budge, and you'll wind up with a 5 lb phone.. it's inevitability.. Some of us may have jammed the charger harder and more times into the little port causing it to become looser, faster-- but over time.. no matter who you are .. whether it takes 1 month, 1 year or 5 years-- it's going to EVENTUALLY become looser..
Q : Do i think HTC should replace this for FREE for all it's users?
A: YES! I 100% BELIEVE HTC SHOULD REPLACE A PRODUCT THAT COSTS $600 DUE TO NORMAL WEAR AND TEAR ON IT'S DEVICE DUE TO A DESIGN FLAW THAT ALLOWS 'NORMAL WEAR AND TEAR' AND 'NORMAL USE OF CHARGING' TO CAUSE THE CHARGING PORT TO BECOME LOOSENED ... EVEN IF IT'S TRUE THAT IT'S INEVITABLE WITH TIME AND USE NO MATTER HOW WELL DESIGNED IT MAY BE.. IT SHOULD STILL BE REPLACED FREE OF CHARGE, ESPECIALLY IF IT HAPPENS IN LESS THAN 1 YEAR WHILE UNDER WARRANTY!
