Samsung Galaxy Note 8.0 Review

In an attempt to quantitatively measure the Note 8.0's battery life in a controlled benchmark environment, we ran two tests. For a more controlled setting, we used AnTuTu's battery rundown test. This a newer test for us, so we're still building out our baseline reference numbers still. For now, we can see that it slots between the Note 10.1 and Transformer Pad Infinity TF700T. This test is fairly intense, ramping up CPU cycles in an effort to drain the battery as fast as possible -- it's a solid look at endurance under duress and heavy use.

To give you a more realistic look at what to expect, we also used the device over a number of days as any average consumer would. We had Wi-Fi connected, screen brightness set at 50%, and engaged in watching a bit of Netflix, chuckling through a few YouTube clips, reading a bit, scrolling through the day's news, tossing a few pigs in Angry Birds, and browsing the Internet. In moderate off-and-on use, we managed to eke out about two days of use. When we used it much more heavily (editing spreadsheets, running benchmarks, etc.), we saw it last right around 14 hours. The Galaxy Note 8 took approximately 3.5 hours for the battery to fall to 80% after a full charge. That's roughly in line with similar-sized tablets on the market today, but it's not a standout performance either.
