Asus Zenfone 3 ZE520KL: User Review

by Terek

Friday, October 6, 2017


I’ve had my Asus Zenfone 3 (Ze520KL)  for 5 months now and I must say, it’s the best choice I’ve made since buying my laptop. This Zenfone was a gift from my mother. She got tired of not being able to get a hold of me after my last phone started giving too many problems due to experiencing some water damage. She gave me a budget and told me to choose a phone I liked and she’d buy it for me.

I decided the new smartphone would be an android phone because I wanted access to the Play Store. I knew I didn’t like bulky smartphones. To me, they seemed to be more of a burden than a benefit. So, I started searching online for a new smartphone.  Aside from the budge, the only requirement in choosing a new smartphone was, the new one had to be an overall upgrade to the last phone i.e. camera quality, storage space, battery… everything.

I happened upon the Asus Zenfone 3. I had no prior experience with Asus smartphones and initially, I was a bit skeptical. But in the end, I chose it based on the specifications and the user reviews. I must say this Zenfone did not disappoint.

Battery Life & Charging

It has a very strong battery life. It charges in roughly an hour and a half with its USB-C charger.  I rarely push the Zenfone to its limits. I’m used to having a smartphone that can’t handle much multitasking, so I tend to only have one or two apps open at any given time. I don’t really stream videos or use the internet that much on my phone either.

All of that combined with the ZenUI’s efficient power saving functions, allows my battery life to last up to 60 hours before needing to be charged. But most times I try to keep my battery above fifty percent. This is because of the USB-C charger. Although it charges my phone fast, in the event I don’t have my own charger, it’s a rare charger to come across on my island.

Performance & Design

It is a light, easy to handle smartphone that fits perfectly in my hands. With a 5.2-inch touchscreen, the screen is big enough to read ebooks off, while being small enough that I don’t feel like I am carrying around a tablet or iPad. It’s also slim enough as to not make my pocket feel bulked down. I walk around a lot, and I prefer not to feel like carrying my phone in my pocket is slowing down my movements.

The most convenient thing about this phone is the fingerprint scanner, and its location, below the rear camera. It is so easy to tap the sensor with my finger to unlock the phone, and/or answer incoming calls. Especially, with friends who are always trying to figure out my password.

Thanks to my Zenfone 3, I no longer need to walk around with an iPod for music, a tablet for reading, and my cell phone. Now I only need my Zenfone. With 32 GB of internal memory, I can travel around with music, books, even movies if I so choose to, all on my phone. And with the power efficiency of the Qualcomm Snapdragon processor, I don’t have to worry about my battery being drained by whatever I choose to do in under an hour, which was the case with my previous phone. The ZenUI 3.0 interface is very crisp, efficient, and user-friendly. It runs multiple apps seamlessly and it transitions between them in a very fluid manner. It doesn’t overheat or even gets warm. It handles all of my needs with ease.

Strength & durability

The Zenfone 3 is an exceptional android device. In my opinion, everything about this phone screams top quality. Both the front and back of the phone are encased in 2.5D Corning Gorilla Glass 3, making it not only aesthetically appealing but it’s also very durable. Its design is a sleek blend of glass and metal.

In the time I’ve had my Zenfone, there was only one noteworthy fall. My sister knocked the phone off the side a shelf that was roughly 4 ft. up off the floor. The Zenfone fell ‘face-first’ to the floor, but to my great relief, the phone was completely unharmed. I would also like to add that my phone has had a fair bit of run-ins with water. I wouldn’t go so far as saying this phone is waterproof, but it’s safe so long as water doesn’t get into the interior of the phone.

Favorite Feature: Main Camera

My favorite feature of this phone is the main camera. Something I only learned after purchasing the phone, is the Asus Zenfone 3 is built for photography. The Zenfone’s PixelMaster 3.0 captures the most vibrant and realistic pictures I’ve ever seen on a smartphone. At first, I thought this was just my opinion, but even my friends were surprised at the quality of the pictures I took during our last hiking trip.

I’ve always had an interest in photography. A picture really can convey an entire story. I thought I would have to wait a long time and save to buy a decent camera, but with my Zenfone, I can at least start learning the tools of the trade. It’s something I’m very excited to start doing and the fact that I can start with my smartphone, a gift from my mom, gives me a feeling of deep appreciation. Every chance I get now I’m taking pictures of things I find picture-worthy.

Worst Features: Camera

The best part of the phone is also the worst part. The main camera has a 16-megapixel quality camera, but the front camera is only 8-megapixels. This is not to say by any means that a camera with 8-megapixel picture quality is a bad thing. In comparison to the back camera, however, it seems a bit inferior, which bothers me a bit.

Overall Review

Generally speaking, this Android-based smartphone is a powerhouse. It actually feels like a bit of a steal for the price. I personally I love my Zenfone 3. If anything happens to this phone, I’ll be looking into the Zenfone 4 next. If Asus keeps this style of a smartphone, I would say they have a customer for life. I would absolutely recommend a Zenfone to anyone looking for a new smartphone. So if you in the market for a durable sleek powerhouse smartphone that takes high-quality photographs and is a quality buy, I recommend you get an Asus Zenphone. I would give this phone an (8/10) rating of the overall experience.
