Hello everyone,
I am conducting a survey (more like research) in order to find a correlation between components (software and hardware) and battery life. I am doing this because I have two friends with identically configured T510's with vastly differing battery lives. In addition, my own T400 doesn't quite meet the tabook ratings for battery life. But beyond that, this information will benefit those who already own a ThinkPad (how to improve their battery runtimes) and prospective ThinkPad owners (how to pick the most power efficient components). Thus I am asking for a few minutes of your time for the following information as much as possible:
Please refrain from commenting on other people's posts on this thread for the sake of tidiness.
I am primarily interested in T-Series as the W-Series generally lives with the expectation of lower battery life, and the X-Series with higher battery life, but post anyway.
Thank you in advance for your participation. I will post tallied results at the end of the year. Hopefully enough people will have chimed in.
Happy ThinkPadding!
* Actual battery life will be defined as the runtime under normal office conditions/light web browsing/note taking/etc. It's not very rigorous, but it's a tradeoff between statistical accuracy and convenience. OPTIONAL: Extrapolations of a full battery runtime (in case you use charging thresholds) can be done using the formula Δt/Δ%, where Δt is the runtime to drain Δ%, where Δ% ie expressed as a decimal value between 0 and 1.
