Usage
The log file can be used to tell you how long the battery lasted (with some limitations, see
below), but it is most useful for graphing discharge curves in order to improve Rockbox’s
estimation of battery level and time remaining. The battery log (
battery_bench.txt
)
is in CSV format (comma separated variables) and thus can be easily imported into a
spreadsheet or similar program.
Limitations
As
Battery Benchmark
needs to write the data held in memory to disk in order to
save them, it is possible that should Rockbox shut down due to low battery then there
will not be enough power remaining to write the data to disk. Therefore all measurements
since the previous save will be lost.
