If you need a smartphone that packs a great battery, you might need to look at the Asus ZenFone 3 Max. It is one of the many phones that Asus has released in its lineup and promises steady performance on the user end.

Running Android 6.0 Marshmallow with Asus' Zen UI 3.0, the ZenFone 3 Max feels smooth on the senses. The Zen UI is packed with a load of features that can help you in basic tasks. However, for those who are in love with the stock version of Android which phones like Motorola and Nexus have to offer, it can be a turn-off.

Coming to the battery again - which is its main jewel - the ZenFone 3 Mac accompanies a 4100 mAh battery that gives up to 20 hours of talk time, or up to 18 hours of Wi-Fi usage. You can also put this battery to use as a power bank to charge your other gadgets. With this battery, the phone can easily run for more than two days with moderate usage, which is something to rejoice at for battery lovers.

Extensive battery aside, the Asus ZenFone 3 Max has LTE, and in addition a fingerprint scanner on the back, alongside a 13 MP camera. Different components are a 5.2-inch 720p display, double SIM support, a quad-core MediaTek MT6737 processor, 2 GB of RAM, and 16 GB of expandable storage space.

The camera is capable of clicking quality images even in low light, ad with the price range it comes at ($149), it leaves little to complain about. Also, the 5.2-inch display is not full HD, but it just does the job of viewing images and videos at different angles.

The combination of its processor and RAM is capable of handling day to day tasks efficiently. However, you may experience a bit of lag while playing high-end games.

The ZenFone 3 Max is a big "yes" if you are looking for a phone with a great battery backup in a low price range.
