We’ve got here Asus’ try, and hopefully a success in competing in Android phone market with the big boys. Yes, Asus isn’t really an unpopular company, but they aren’t exactly ruling the mobile phone market. That’s why they decided to go with Asus Zenfone 3s Max ZC521TL, a smartphone sporting some decent specs for an affordable price. How affordable, you might ask? Well, you’ll find out right away. First of all, it sports a very good, pleasant to the eye but also an ergonomic design to it. It will fit in your hands comfortably, that’s for sure, because of curved edges on the back.

It isn’t the thinnest or the most lightweight phone out there, but Asus Zenfone 3s Max ZC521TL features a decent size to it. That’s accompanied with a 5.2-inch screen and only HD resolution of 1280 x 720p. It’s not exactly blurry, but we guess they couldn’t fit a full HD screen for this price range, which is okay. At least we’ll have Android 7.0 (Nougat) operating system to use, unlike Asus Zenfone Live ZB501KL, which is good. It allows for an easy interface navigation and usage and adds a modern look.

Next up, the camera. It’s a solid 13MP camera on the back, sporting a common dual-LED flash. On the front is an 8MP camera to allow for decent selfies on those nights out. This is a common combination even Samsung uses on their Samsung Galaxy J7, so we’ve got no complaints there. You will also be able to record 1080p videos at 30 frames per second, which is great. Battery wise, this is one of the best Asus Zenfone 3s Max ZC521TL specs and its main selling point. We’re talking 5000 mAh Li-Po battery capacity. Yes, that isn’t a typo, it’s that much. It will allow for multiple days of usage, considering the screen resolution.

It’s time to see what’s under the hood. The specifications of Asus Zenfone 3s Max ZC521TL are mid-range, sporting an Octa-core MediaTek 1.5 GHz Cortex A53 processor underneath. It’s all accompanied by Mali-T860MP2 GPU, which isn’t known for top-end gaming but will run less demanding games. We’ve got 3GB of RAM in the package, which is just decent, but slowly growing old with phones having 8GB like on Razer Phone. But you need to remember that one costs quite a lot more, and Asus Zenfone 3s Max ZC521TL price is only around $270.

In the end, we have the internal memory of 32GB, which should be enough for all the basic app and storage needs. But in case you just need more,  you can use a microSD card that goes instead of 2nd SIM card. The fingerprint sensor doesn’t always work, but you’re getting a ZenUI 3.0 feature. This means the default Android OS will get a new, fresh look to it. It’s perfect for business people that are looking for a simple option. So, if you’re not looking for a gaming beast, but for a reliable phone to last you a day or two reliably, it’s the way to go.

    Another mediocre Asus smartphone

    Asus was never one of my favorite manufacturers, and i didn't buy this phone; i actually got it for my birthday. The performance is…mehhh. It's good but nothing special with its HD display and not-that-good camera, but at least i've got 3 GB of RAM, good for multitasking.
