I would just have to remember about a decent power bank. There is no need to curse reality, Samsung Galaxy Z Fold 2 received a two-piece battery with a capacity of 4500 mAh with 25 W fast charging and 11 W wireless charging, as well as reverse charging. The battery is divided, among others in order to ensure perfect balance of both housing parts. As you can see, the capacity is not impressive, but I can understand that the larger batteries simply could not be squeezed into Fold... And unfortunately, it is a smartphone that will last for a day without charging. Of course, as long as you intend to use it.
If you do not open it, and you light up the external screen only occasionally, Galaxy Z Fold 2 may last up to 2 days. But you don't buy such phones so as not to enjoy the big screen, multimedia, high performance or 5G - right? My practice of using Galaxy Z Fold 2 looked simple: unused, it landed on the induction charger. That way, I was able to fully use it all day to at night - put it back on slow charging again. However, it must be remembered that the equipment was used intensively, largely replacing PCs and laptops.
Will I criticize something in Galaxy Z Fold 2? Those who waited until I finally grumbled should be happy by now. The fingerprint reader is pretty average. It is classic and placed on the side - which I like and appreciate. Unfortunately, I have some reservations about the pace of its operation and the reliability of its readings. This is not a flagship level. Believe it or not, I haven't noticed that this reader is dramatically better than the one I used recently in the cheap POCO. And it should be! I definitely preferred to use the well-functioning, but of course less reliable, security in the form of facial recognition. It was quick and more convenient to use with the housing open.
