An Inconvenient Truth about Mobile

How often do users charge their smartphones? Are mobile phones mobile enough to hold charge for a day? How does short battery life affect user behaviour and user experience?
We answer these questions via the following infographic generated by analysing data collected by Estar Battery Saver from 37k Android users across 100+ countries.

All the data logged by Estar Battery Saver app is strictly anonymised; we don’t collect any information that may identify individual users.

Breakdown of users using external battery backup is obtained from here.

Estar Battery Saver logs remaining battery percentage and phone charger connect/disconnect events; we use these event timings to generate charging and blackout related insights. The phone usage is defined as the ratio of screen-on time over wall-clock time.
