Battery life index

Battery life index tells you how many days you can use the device with a single charge; i.e. an index of 1,00 means that the battery lasts exactly one day. The index is calculated using real power consumption measurements together with a special usage profile, consisting of over 20 use cases.


Battery life rating is also given to each device, using grades from A to G. Exceptionally good devices can get A+, A++ or A+++ grades.
