Battery Life
The Galaxy Note 5 has a 3,000mAh battery. The smaller-sized Galaxy S7 edge sports a 3,600mAh battery. That alone explains a lot about the battery life on this device. Despite some heavy usage during the review, at no point did I feel insecure about running out of battery or to carry a power bank just in case.
I consistently end the day with about 20-30% of battery remaining, and I am usually home pretty late at night. On at least two occasions during the review period I hit five hours of screen on time, while I still hit over four hours on the day I was out shooting camera samples and running benchmarks.
Plenty of screen on time
It’s important to note that I was using this phone for a week. Over time I’m confident that battery life will be slightly better because of the Smart Manager setting.
Inside Smart Manager is a feature called Battery Optimisation, which monitors the background processes of each app over a three-day period. What it then does is to optimize how these apps run in the background, based on how often you use the app.
Samsung does not state what optimisation processes take place, or how much battery life can improve, but the battery life on my review unit has been progressively better since the first two days of using it.
