The battery in the Lumia 1520 is sealed, but it has the reasonably big capacity of 3,400mAh. The phablet comes with built-in wireless charging, a feature that was missing in the 1020. To make use of it however, you would have to buy separately a Qi wireless charger - these days those come in many shapes and sizes.
The massive battery, light-weight Windows Phone OS and power-efficient display were made to count in video-playback and web browsing test. They surely helped the Lumia 1520 achieve an amazing score despite the huge estate to light up. Talk time and the overall stand-by endurance are great too thus the 107h top-notch rating is no surprising.
Anyway, with an overall rating of 107 hours, the Lumia 1520 is well ahead of the other phablets we've tested so far. What this number means is that the Lumia 1520 should manage four and a half days on a single charge if used for one hour each of calls, web browsing and video playback daily.
The Nokia Lumia 1520 has a 6" IPS LCD screen of 1080p resolution, the pixel density works out to 367ppi. The LCD incorporates Nokia's ClearBlack tech - a set of polarizing filters, which minimize glare. Plus, Gorilla Glass 2 on top for protection.
The capacitive touch sensor on the display features the supersensitive touch technology that allows it to detect fingers even through winter gloves.
The 1520 comes with the Lumia Color Profile option in the settings, which gives you two sliders to play with - one for color temperature (which spans the cool, neutral and warm range) and color saturation (natural to vivid).
The Nokia Glance screen keeps the clock and notification counters visible even after you lock the screen. This could be set to appear only for a little while after you lock the screen, intermittently on and off and always on. There's a separate always on setting for when the device is charging. A Night mode allows you to pick a different color for the Glance screen info - Red, Green or Blue - if the default White setting is too bright for your sleepy eyes.
One new option in GDR3 is the screen rotation lock. That's an important feature for a phablet, but unfortunately it's only accessible from the Settings menu, which means you have to leave the app you are using to change it, there are no quickly accessible toggles here (this is a common problem for any settings in Windows Phone).
As we already mentioned, the Lumia 1520 screen is tack sharp. Due to its large diagonal, pixel density drops below 400ppi, but 367ppi is still better than what most people's eyes can resolve, especially when you consider you tend to hold a phablet further away from your eyes than a phone.
Nokia Lumia 1520 display matrix compared to the Samsung Galaxy Note 3
The viewing angles are excellently wide with only a minor shift in contrast when going to extremes. Color rendering is good and, as an added bonus, you can tweak the white balance and saturation to your liking. The one weak spot of the display is the black levels, which are not as great as on AMOLED, but the overall contrast is still quite good.

The ClearBlack tech does help minimize reflectivity. The relatively low brightness however hurt the outdoor performance.
