A:Answer I had an iPhone 6 before getting the XS Max. I think I get an extra day before I have to recharge the phone. But it really depends on the amount of usage. On your phone, have you gone into Settings >Battery >Battery Health? If it's less than 80%, you may need a new battery. Apple is replacing the iPhone 6's battery for $29 until Dec. 31, 2018. I took my 6 in for a battery replacement. The Battery Health on it was 78% I believe, which meant it could only charge up to 78% of what a new battery could charge at (100%). Also, if you have Background Refresh option on, (Settings >General >Background App Refresh) try turning it OFF or if on, only select the Apps you believe absolutely need to be refreshed in the background. My wife was complaining about this same problem (needing to recharge her iPhone 6 daily). Once she turned OFF this option, she didn't have to recharge her phone every day.
