Windows 10 Power management

Win 10 scenarios covered

  • Battery Saver — For Better reporting accuracy, OEMs may need to run E3 micro benchmarks
  • Modern standby — Cheaper alternative to connected standby
  • Power scheme settings — Hibernate for CS systems
  • Project Centennial — Converting Win 32 apps to UWP apps

Battery Saver

  • New Windows 10 Shell option which shows battery consumers on the system at runtime
  • This uses a general model of the platform to indicate battery use
  • The accuracy of data is higher if OEM runs micro benchmarks on their platform or use the Maxim chip at an additional cost to the BOM





Modern Standby

Why does it matter?

  • CS hardware requirements do have a BOM adder(Storage and Network)
  • Modern standby allows for instant on
    •     S3 systems from telemetry may have twice as large S3 resume


MS_1 Ms2

  • Background activities (non network related) can still happen
    • Store apps activities
    • Reminders
    • Bth sync
                           Battery drain Hibernate timer OEM setting
Exceptional 9 days or longer battery life Use of Hibernate timer is optional
Ontrack 6 days or longer battery life Use of hibernate timer after 24 hrs is recommended

Modern Standby Implementation


Power management – Hibernate times

  • New Win10 Hibernate Settings for end user
    • Default is same as Win 8/8.1
    • Not to hibernate the system
    • Changing the setting allows the system to Hibernate while in CS
    • Criteria to set the Hibernate values


Lowering power consumption with UWP apps
