Welcome to a Laptop Battery specialist of the Toshiba Laptop Battery
The Satellite L855-15U comes equipped with a third-generation Intel Core i5-3230M CPU with Intel's Turbo Boost Technology 2.0. A dedicated AMD Radeon HD 7670M graphics card with 2 GB of dedicated memory ensures a more than adequate video performance. Our 3D benchmarks will show whether the same holds true for gaming. For comparison, we take a look at both the HP Envy m6-1101sg and the Acer Aspire V3-571G-73614G50Makk (who comes up with these names, anyway?). With an Intel Core i5-3210M 2.5 GHz and a dedicated AMD Radeon HD 7670M as well as an aluminum chassis, the HP Envy comes very close to our test device, spec-wise. The V3-571G comes equipped with a superior Intel Core i7-3610QM 2.3 GHz as well as a dedicated Nvidia GeForce GT 640M GPU, but it suffers from having just 4 GB of memory.
There is also an AMD-based variant of the Toshiba Satellite L855 series with a "D" in its name as well as a less "cool" series called L850 which comes equipped with a black chassis made from plastic.

offers a runtime of up to three hours. We tested it using four scenarios from the Battery Eater 05 benchmark. The Reader's Test turns the screen brightness way down and deactivates all radio modems, thus simulating a reading scenario. Here, the L855-15U manages to survive for a maximum of 4 hours and 34 minutes. Under normal usage (office programs, surfing the web), the battery lasted for 2 hours and 40 minutes. As a multimedia laptop, the L855-15U is not suited for excessively long movies. After just 1 hour and 59 minutes of watching a DVD, the laptop died. Under full load, using the Battery Eater Classic Test, battery life went down to 1 hour and 14 minutes, after which it takes 80 minutes for the laptop to fully recharge.
Toshiba has included a separate energy saving profile, promisingly called Eco. Unfortunately, we didn't see any miracles. With just 3 hours and 40 minutes, battery life was actually worse than during our own Reader's Test. During our normal usage test, 16 minutes was gained. Under full load, the difference between Eco and Standard went down to just 6 minutes.
