Battery Testing Results

Here's a quick update about battery consumption while your phone is inside the OFF Pocket.

Last night I ran a 6.5 hr test and measured my battery levels before and after placing my phone inside the OFF Pocket. Using my operating system's battery level wasn't accurate enough so I installed this great testing app from Nicolas Seriot's GitHub repo:

This  gave me detailed and accurate information about the voltage, current capacity, and more. Using this data, I was able to determine that over a 6.5 hour period the battery percentage decreased by only 2% (0.33%/hr), from 100% to 98%. And that the total current consumption was 106mA (16.3mA/h).

At this rate, my phone's battery would last 258 hours, or a little over 10 days, inside an OFF Pocket. Of course, those figures will either increase or decrease depending on how your phone handles connectivity and your battery size. And I'd still like to carry out more tests with other phones.

Building better diagnostic tools and providing more data about the OFF Pocket is one of my commitments with this campaign. As the campaign continues and with our backer's support, I plan to run more quantitative tests on battery consumption and publish more data.

Thanks again for supporting this project and asking important questions.
