Thanks for reaching out to us about this. Geekbench battery scores are best understood in relation to scores on other devices, and it appears that a score of 906 is within the expected range for an iPhone 5s. See these results for comparison:
A higher work percentage over the length of the battery test may indicate that a device is able to perform more work in the same time period than another device. Small variations can occur due to background processes and other factors. I haven't seen any iPhone 5s devices that have a sustained work percentage under 70%; above that seems to be more typical.

We're working to roll out battery benchmark comparisons in the Geekbench Browser as soon as possible. I'm afraid that we don't have a release date set at the moment, but I'll let you know as soon as I can when the update is prepared.
