One of the most striking elements of Nothing Phone (3) is the Glyph Matrix, ...that small, pixelated rear screen that brings new ways to interact and personalize. However, one of the most common questions among users it is whether keep it on for a long time it significantly affects the device battery. To verify this, I performed a simple but revealing test.
How the test was done
I started from a Nothing Phone (3) uploaded to 100% and I restarted it before starting each measurement. I performed two identical tests of two hours each:
- In the first one, with the mobile phone in airplane mode and the Glyph Matrix turned on as a flashlight at level 3/4 brightness.
- In the second one, exactly the same, but with the Glyph Matrix turned off.
During the first hour I put it in airplane mode without doing anything with it. In both tests, the phone remained at 100% without any change. It was in the second hour, Playing a looped video with the same screen brightness, the differences appeared: with the Glyph Matrix on, the battery drained to 94%, while with the Glyph Matrix turned off it ended up 95%.

Results: real impact on battery
The final difference was only one 1% after two hours of continuous use of the Glyph Matrix fully switched on. If we extrapolate this data, it suggests that the impact on battery life is minimal and barely noticeable in everyday use.
To put it in context: if someone turns off their mobile phone at 7 a.m. and reloads it at 11 PM, We're talking about approximately 16 hours of use. During that time, with the Glyph Matrix on all day in flashlight mode (which consumes the most LEDs and is quite unlikely to be used that way), the extra energy consumption would be... around the 8% battery. A fairly small impact on the device's overall battery life.
Final considerations
It should be noted that I performed the test with the Glyph Matrix in mode flashlight, with all LEDs lit, which is the scenario with the highest consumption. In the case of using the Glyph Toys For essential notifications, where not all LEDs light up at once, the energy consumption will be considerably lower.

Putting this last assumption on the table, with a actual use of the Glyph Matrix, For example, activating the Glyph Matrix several times a day using its rear button and receiving essential notifications in moderation, I estimate that the consumption could do not exceed 1% of the battery of our Nothing Phone (3).
In conclusion, the The Nothing Phone's Glyph Matrix (3) barely affects battery life in prolonged use. Even in the most demanding scenario, the difference in consumption is minimal, so we can enjoy this feature without worrying too much about battery life.
