Smart glasses display data from a background information system on a computer screen/display placed in front of the eyes. Displays can be projected on glasses’ lenses or brought directly to the eyes. The most important thing is that smart glasses do not distract the user from the environment.
Smart glasses are also often referred to as “augmented reality”, which is basically a way of enhancing (and strengthening) the real world by adding information from an information system.

The Samsung Galaxy Z Fold 3 is the third set of Samsung’s foldable phones. Samsung keeps improving on the foldable phones’ durability and performance and the Galaxy Z Fold 3 is the first foldable smartphone with support for the S Pen.
Now let’s look at some reviews of the latest Samsung foldable phone.

Samsung Galaxy Z Fold 3 price

The Galaxy Z Fold 3 price is less expensive compared to when Galaxy Z Fold 2 was launched but foldable phones are still more expensive than normal high-end smartphones like Samsung Galaxy S21 Ultra or iPhone 12 Pro Max.
The price for Samsung Galaxy Z Fold 3 starts at $1,799 (£1,599), meanwhile, the price in Nigeria is about N750,000 for a model with 256GB of storage, and for a higher capacity, you can get a 512GB Z Fold 3 for $1,899 (£1,699 ), and the price in Nigeria is N780,000.
For those in the US, Samsung is offering a deal of up to $800 off if bring in an older device, which could be your phone, tablet or wearable device, or any combination of the three, you can also add up to four devices if you want to get the maximum value.

Samsung in the UK offering up to £250 if you can turn in your phone, and when you pre-order, you will get a Fold Starter Kit which comprises a charger, a case for your Z Fold 3, and an S Pen stylus.

Samsung Galaxy Z Fold 3 Battery life and charging

The Z Fold 3’s battery life is not impressive. The dual 4,400-mAh batteries are actually smaller compared to the ones in the Fold 2 which is 4,500mAh. The 4,400mAh battery supports fast charging at 25W and also supports up to 10W wireless charging. Considering the fact that the phone works with the combination of 5G connectivity and two screens that run at 120Hz, better battery life should have been used. As it is, the battery life barely makes it through the day.
Another thing you should know is that there’s no charger in the Galaxy Z Fold 3’s box package, so to charge it, it’s either you use your existing charger or buy another one. This is something similar we saw with Apple when it released its iPhone 12 series.

Samsung Galaxy Z Fold 3 Displays
