ZTE Grand X 4 Final Thoughts

Battery Life, Calling & More:

The battery life on the Grand X 4 is absolutely amazing. After using my Nexus 6P and other mainstream devices, you get used to trying to conserve power to make it through the day. With the lower screen resolution as well as a huge battery, I can easily get through 2 days of medium-heavy usage with this ZTE device. I left WiFi enabled after I was pretty much done this review and it lasted for well over 4 days – with a day and a half to go. Keep in mind that I was still checking notifications on this phone as well as playing games and using it to monitor the DJI Mavic drone as well.

In terms of size, the Grand X 4 is a bit larger that some of their earlier “Grand” offerings, but the size is quite manageable as it has a slim profile, albeit a tall screen. It is very pocketable and is marginally smaller than my Nexus 6P.

ZTE includes a solid SMS/Messaging App and the gallery and image editing features. I'm very impressed with the entire gamut of features, applications and the entire package out of the box. The stock keyboard is solid but after using Swiftkey, I had to install it as the prediction is much better. Again, the experience is pretty much what you'd expect with a Nexus or Google Play Edition device. I love the basic, non-frills experience.

When it comes to call quality, the ZTE Grand 4 is a solid performer, but looking back at the Grand X 2, that older unit had better call quality. I had a few complaints with this device that I was a bit "muffled". The call quality in ideal situations is good, but in a loud environment, the call quality suffers a bit. The built in speaker is a bit louder and actually clearer than my Nexus 5 as well. It's no HTC One M8 by all means, and the location of the ZTE speaker is not all that desirable, (located lower back - like many Galaxy devices), so if you lay the phone on the back, it does muffle the sound. All that aside, it's still a decent speaker that works well for hands-free calling or for listening to music and other media.

On the last page, we’ll wrap things up with our final thoughts.
