My Nexus 6 is having trouble charging lately and I'm not sure if its the charging cable going bad or the charging port in the phone itself. If its the phone then a wireless charger will be the only way to keep my phone usable.
Most people don't think about practical considerations like this until such a situation arises.
When phones had removable batteries you could charge them externally and if the charging port broke you were fine.
Then they sealed phones to make them pretty but told us it was ok because we could use fast charging. But if your phone charging port is busted then you can always fall back on wireless charging UNTIL they decide that metal phones are prettier still so no wireless charging for you.
Charging port breaks? Send it in for repair and have your phone gone for a week or buy a new one. We all know which the OEMs would prefer.
My Nexus 6 isn't even a full year old and I DON'T want to get a new one, and thank god I won't have to because its not metal and has QI charging.
BUT if you get a Nexus 6P? Well if the same thing happens to you? Well you're **** out of luck, get a new phone.
