I'm not seeing the great battery life on the 6plus. Friends say they get 2 days. I was lucky to get one. It does not seem any better than my 6. And boy what a pain in the ass to charge. Took a 2.5 hour road trip plugged it in with 57%. By the time my drive was over only 97%. 2.5 hours to charge 40%. That's not to great. Anyone think maybe I have a bad battery ?
