Both the Sony Xperia ZL and the Xiaomi mi 4 are solid phones. Here’s how the match up when compared against one another.
Sony Xperia ZL
The ZL is running Android 4.4.4. It has a thickness of 0.39 inches. It weighs in around 151 grams, making it an average sized phone. The display size is 5.0 inches which is definitely on the large side. It also has a resolution of 1080 x 1920p which is excellent resolution, especially for a phone. The camera on the phone is 13 MP which is also excellent. It can shoot in 1080hp with the HDR mode and video calling. The front-facing camera is 2 MP which is adequate if not perfect. The phone has a quad core 1500 MHz processor. It has over 2 GB of RAM. The built in storage is 16 GB. The battery is 2370 mAh which is good enough for 10 hours of talk time.
Xiaomi Mi 4
This phone is running Android 4.4.3 for an OS. It has a thickness of 0.35 inches and weighs around 149 grams making it comparable in size and weight to the Xperia. It also has a 5.0 inch display with the same 1080p resolution. The camera is exactly the same as well at 13 MP. The Xiaomi can shoot in 4k resolution however, as well as in the 1080p HD video. It also has an 8 MP inward facing camera. It has quad cores and over 3 GB of RAM. It has 4 times more built-in memory as the Xperia and its battery is better as well with 3080 mAh cap.
The Xiamo Mi 4 is clearly the better phone since it has a better processor, shoots way better video, and has an extra Gigabyte of RAM. It also has a better internal facing camera by a factor of four. So you’ll be able to run apps more smoothly, capture better video, and likely use the phone for longer. Beyond these elements, the phones are similar.
