I have the Samsung Galaxy S5 and I'm going to buy the wireless backing for it that samsung came out with. I need a wireless charging pad obviously so which one do I get? I have the otterbox symmetry...will that affect charging speeds at all? if so what pad do I get that will work with the otterbox symmetry?So for a recap: what wireless charging pad will work just fine with otterbox symmetry, has an idle mode (to prevent overcharging) and hopefully is a stand up charging pad. In other words will be a little stand for viewing movies or something. Thanks! Most likely you all will tell me the otterbox symmetry will work with any charging pad but I'm just asking to be sure. I don't want it to charge slower because of the case. Thank you guys!
