Oppo N1 CyanogenMod edition review: Pure mind

Display

Easily one of the key selling features of the device, the 5.9" screen of the Oppo N1 has a resolution of 1920 x 1080 pixels, resulting in around 373ppi. Oppo puts the screen brightness at 450 nits, not all that much for an IPS LCD like the N1's but in reality the screen looks pretty bright.

Hardly a surprise for an IPS unit, the side viewing angles are excellent - it's a high-quality screen, no doubt about that. The screen's digitizer is super-sensitive and the phone can be used with gloves (if you turn that on in the settings menu).

The pixel arrangement is standard RGB with an equal amount of green, red and blue pixels in a line. Below you can see it magnified using our trusty microscope.

The contrast of the screen is pretty good and about in line with the excellent Find 5 display. Color reproduction is also pretty great adding up to great image quality screen.

The only sub-par element of the otherwise great display is its sunlight legibility. The less than stellar brightness combined with the very high reflectivity add up to pretty poor contrast when exposed to direct sunlight.

Battery life

The Oppo N1 running ColorOS managed to get a battery rating of 79 hours in our dedicated test. We were eager to see the times posted by the CyanogenMod version with a near stock version of Android.

Well, it turned out Oppo's optimizations to the ColorOS were doing a better job than whatever the CyanogenMod team put together, as the phablet only managed 59 hours now. That's right, a scorching 20 hours less.

Mind you, there's Android 4.3 underneath CyanogenMod 10.2 which is the latest version available for the Oppo N1 at the time of writing, while ColorOS is based on Android 4.2. Here's hoping CyanogenMod will manage to get closer to those 79 hours in the KitKat version 11.
