The E205 came with a 5,800mAh, 6-cell Li-Ion battery. Below we ran our standard Battery Eater Pro test, which loads both the CPU and GPU until the battery runs out of power. During the test, Wi-Fi was enabled, audio was on, and the screen was set to always on in the power settings control panel of windows. The following benchmark is more of a worst-case scenario test setup. Since it continually taxes the graphics processor as well as the CPU, battery life is likely to be longer under lighter duty workloads and scenarios, such as simple word processing or Web surfing.
Toshiba claims that the E205 has up to a six-hour battery life. We didn't come anywhere close to that on our tests, as our chart shows. We barely eked out just under and hour and 40 minutes, which isn't even enough time to watch many Hollywood movies. But as we mentioned, our test is best seen as a worst-case scenario. In our more casual day-to-day use of the laptop we saw battery life times that were closer to the three or four hour mark. Obviously, depending on how you use the E205, your battery life can vary considerably. This chart represents a wide-swath of laptops HotHardware has looked at, and they were all tested using the same methodology--so, at least when comparing the E205's battery life performance to these other laptops, the E205 has one of the poorer battery life times we've seen.
