Has anyone replaced the iPhone 6 Plus battery? I'm interested in hearing how best to do it. Send it to Apple? Buy a kit online? Any tips, tricks, or gotchas would be appreciated. Also, I'm approaching one year with my iPhone 6 Plus (I love the phone, better than the 6s Plus, which I've tried for a few days) and I'm assuming the battery should be replaced after one year because it does seem to run down faster. Am I right? Thanks!
