An examination of the advantages and disadvantages of the specs and capabilities of the Xperia Z4 SoftBank. How highly does it rate in terms of accessibility and performance in comparison with other smartphone? We reviewed the Xperia Z4 SoftBank to see if it was a good buy.

Features, Performance, and Reviews for the Xperia Z4 SoftBank

The camera function of Xperia Z4 SoftBank

The Xperia Z4 SoftBank has a 20.7 MP main camera that lets you take photos and videos in a quite high resolution. You may be a little dissatisfied with it in some situations, for example when you want to capture scenery in very high resolution or print out beautiful photos, but this should not be an issue you run into very often.

The Xperia Z4 SoftBank comes with a 5.1 MP pixel camera, which is a standard level. It's perfectly fine for selfies, but may be not as satisfying if you wish to take photos of large numbers of people, or make printouts.

The battery performance of Xperia Z4 SoftBank

The Xperia Z4 SoftBank has a relatively large battery with 2930mAh. The Xperia Z4 SoftBank has a good battery life compared to other smartphones. You won't feel stressed even if you spend all day surfing the web or on Twitter and you can also watch videos or play games on the go without having to worry too much about the battery. If you watch videos or play games for too long, however, you might want to watch your battery a bit.

Xperia Z4 SoftBank's size

The Xperia Z4 SoftBank is 2.8inches (72mm) wide, 5.7inches (146mm) tall, and 0.27inches (6.9mm) thick. I can just barely use it with one hand, so it may feel big to some people. In the case of the Xperia Z4 SoftBank, it weighs about 5.0704oz (144g). The weight is such that it's hardly noticeable even when using one-handed. However, some people may find it tiring to use for long periods.

In giving an overall rating to the Xperia Z4 SoftBank, while it may be slightly difficult to hold, it shouldn't be much of a problem when considering its general strengths and weaknesses.

Xperia Z4 SoftBank's screen

The Xperia Z4 SoftBank has a 5.2 inch screen. The iPhone X has a big screen, which very likely won't ever trouble you. Just be aware that it's not a very good size for writing long blocks of text.

The screen of the Xperia Z4 SoftBank is extremely clear, and it's able to display everything from images to videos and even video game graphics in perfect clarity.

The CPU performance of Xperia Z4 SoftBank

The 2.0GHz+1.5GHz×8(OctaCore) processing speed of the Xperia Z4 SoftBank is on the higher side, so it should be able to run most apps with no problems. The performance of this phone is at a high level when compared to others released on the market so far. You can play a comparatively large amount of 3D games with next to no issues.

The Xperia Z4 SoftBank has 3GB of RAM, so it has plenty of space. In rare cases this amount of RAM might not be sufficient, but there shouldn't be too much stress on the machine with this amount.

The Xperia Z4 SoftBank has the overall operating speed of a high-end smartphone, so it will hardly ever cause you trouble. But you might need to be careful when using heavy apps like 3D games a lot.

Xperia Z4 SoftBank's storage capacity

The Xperia Z4 SoftBank has 32GB of data storage, which is plenty for taking photos, but for people who frequently shoot videos or have lots of games installed, this may not feel like enough space.

Since the Xperia Z4 SoftBank is compatible with SD cards, you'll be able to easily expand your storage capacity; you won't need to worry about how much internal space it has.

Overall assessment of Xperia Z4 SoftBank

The Xperia Z4 SoftBank is a high-performance smartphone. You're not likely to experience any inconvenience in general use.
