It won’t. It never has and I don’t expect that’ll change. My S9 is great now but so was my Note 8 before that and S8+ before that. Give it a month or two and you’ll see it’s time to reset and start again or you’ll begin to see more lag and your battery dying sooner than it had been. No hate just truth.//uploads.tapatalk-cdn.com/20180321/37a31e97a7431be31c6c0fe8cf9e7be6.jpg
My 8+ 835 version continued to have great battery life for the year I had or it, so disagree. There seems no technical rationale for the assertion it would not. I have not had that experience with any Android phone. G1, Incredible, Droid 2, Razr, S4, Note 4, MX Pure, S7, Note 7, S8, S8+. None. Added: Use my S8 still for Gear VR, which is a battery drainer. Still holds a charge well.
