As someone who used an S21 FE for almost a year - I hope they have found a way to improve battery life. I was usually not able to make it through a full day with light-moderate use, or at least I was plugging it in to charge several times a day when it was convenient (at my desk at work, in the car while driving, etc.) and I even switched to an iPhone I have on standby when I went on vacation for 4 days because I knew the battery would last through a full day. It’s not a bad phone outside of that, though the lower amount of RAM was annoying at times too.
