Battery Life

Underneath the Milky way Note 4's rear cover is a 3,220 mAh battery running at 3.85 V, delivering a total capacity of 12.four Wh. This is a slight upgrade on the Galaxy Annotation 3'due south battery (12.1 Wh), which isn't surprising because both devices have the aforementioned sized display. Although the resolution has increased, which in turn requires more processing power, this will probable be kickoff by efficiency improvements in each SoC.

For the following benchmarks I merely had admission to the Exynos model of the Milky way Annotation 4. While these results volition give a decent overview of how the Exynos Note 4 fares in terms of battery life, they won't necessarily give a practiced representation of mileage on the Snapdragon model. For the Note 3 and S5, for example, the Snapdragon model gave a few hours of extra life compared to the Exynos model. I'll accept to get longer hands-on time with a Snapdragon Note 4 earlier I can conclude which model delivers the all-time battery life.

One affair that should be noted for the Exynos variant is that this is the first smartphone SoC I've reviewed that'due south manufactured using a 20nm procedure. Previous Exynos devices, such as the Galaxy S5 G900H and Galaxy Annotation 3 SM-N900, had 28nm SoCs inside, meaning the Note 4 should come across efficiency gains from moving to a smaller procedure node.

For video playback, the Note 4 Exynos variant lasts for only as long equally the Note 3'southward Exynos variant. This indicates that any efficiency gains in the new SoC's decoding block have been showtime past losses in other areas, potentially the higher-resolution display.

In our web browsing tests the Exynos Galaxy Note 4 performs surprisingly well. In both Wi-Fi and LTE situations this Note 4 variant outperformed the Snapdragon Note 3, which already produced decent bombardment life. Having competitive bombardment life is a pregnant step forrad for Samsung's silicon division, though I'll have to run across how it performs against the Snapdragon 805 model at a afterwards engagement.

In GFXBench the Note iv lasts just as long every bit the Annotation 3, only less time than both S5 variants. This is even with throttling that takes touch on later on 5 minutes into the run.

Both variants of the Galaxy Notation 4 support quick charging, which is activated by plugging the device into a compatible charger (such as the one included in the box). In the above chart I've compared results for quick charging and standard charging through a 10 Due west wall charger, with both providing acceptable charge times.

Naturally quick charge is a superior charging method, so whenever you have the take a chance you lot should charge the Notation 4 using the included wall charger.

The Milky way Note 4 comes with several power saving modes: a standard one that restricts functioning and groundwork data, and what Samsung calls 'ultra ability saving mode'. When this style is activated, the display switches to blackness and white, all connectivity features are disabled when the screen is off, and a limited subset of applications can be accessed. Although the phone's features are express in ultra power saving mode, information technology'southward very constructive at prolonging life when the bombardment gets low.
