The battery life on the Galaxy S10+ is so good that it is ruining my traditional charging habits. Instead of slavishly charging every night, I just don't worry about it and can be assured that it will be fine the next day. This has happened several times, and now, I'm just getting lazy. I charged it Sunday when I went to sleep, used it a normal amount Monday and Tuesday. I woke this morning to reach for my phone, only to find it in the pocket of my pants. No charge since Sunday, and it was still at 19%! Incredible.
It's not just the large battery, because some phones have even larger capacity batteries. The S10+ actively manages what's running so nothing runs the battery down needlessly. This phone has completely destroyed my range anxiety. I've never had to not worry at all about a battery to some extent.
Plus, I know that if there was a power outage, I could still turn on power saving mode. To be clear, no power saving mode was engaged. My phone was running in normal mode, FHD+ resolution, playing games, reading email, checking FB, the usual. GPS and Bluetooth were enabled the entire time.
