Just got ahold of an S6 Edge Plus and I'm reminded how much I loved that phone. If only it had expandable storage, I would hardly have ever looked at anything since.
This phone was never booted up, was mint in the box, so its battery life is fine. Especially now that I've got it upgraded from Lollipop to Nougat. And it's on the March 2018 security patch. Pretty pleased.
I will probably move on to the Note 9 or the S10, but until then, I'm happy with this.
