Samsung Galaxy Note III Battery Life Tests and Comparisons

Posted on Oct 14 2013 - 9:44am by Brian

We’re always impressed with Samsung’s continuous improvements of device CPUs, displays and designs, but one area that has seen stagnation across all device manufacturers is device batteries. Attempts to improve the user’s battery experience have ranged from wireless charging, to extra large internal batteries. Samsung has gone the latter route with the Note series, so let’s take a look at how the Galaxy Note 3’s 3200 mAh battery stands up to real-life tests.

These tests were performed by Korean site Playwares.

The graph below shows the battery life in hours of each device listed. The orange bar represents battery life (in hours) while web browsing on maximum brightness, and the blue represents the battery life with brightness at the aforementioned 230 CD/?.

As you can see, the Galaxy Note 3 at full brightness comes in at 5 hours of battery life, comparable to the iPhone 5 and besting Samsung’s own Galaxy S4. If you are wondering why the Galaxy Note II’s figures are so different form the Note 3, one must consider the difference in screen resolution as a increased performance cost which will drain the battery faster.
