I do everything on this amazing phone and the battery last all day with about 30 - 35 percent by the end of day which is around 9:30 until 10:00pm. The crease is not as noticeable as i thought it would be. But, it also depend on how you are holding the phone. Once you start, typing, viewing video's, or even on conference calls, the crease is not that noticeable.

Amazing performance in your hands
Came from a Fold 3. This iteration is a good improvement over it. Starting with the Screens, the front stays mostly the same, it is narrow but that is perfect for swipe texting one handed. The inner screen feels different but only time will tell how long the protector will hold up as it did NOT on the Fold 3. Best thing I really the increase in brightness by 700 nits! The lack of bezels is also a plus. Hardware it self feels new and improved. Opening and closing is more secure but the crease looks the same. The gapless hinge is a huge bonus as now it allows for a slimmer profile especially with a case on, although I prefer caseless. A few things about the software/cpu. It is overall a lot smoother but that usually happens with a new release. The animations seem slow at 120hz but you can fix that by lowering to 60hz or opening Dev Options and removing them altogether for a faster feel. Having more apps show in the taskbar is useful for those who switch around a lot. This thing handles multi apps open like a champ without much heating. Games run without a stutter the battery so far gives me 6-8hrs SOT depending on my gaming habits. Camera is a huge improvement over the old Fold 3. Look at youtube reviews and see that it almost keeps up with the S23U in bright and low light, front cam and videos but falls short of the zoom, which I don’t plan to take pics of the moon so not a negative for me. Minimal blur and sharp images of moving objects is what I need and so far so good.
