GSMArena does extensive battery testing of a device as part of their review & what we are trying to do over here is to compare the same for all WP8 devices (barring the Lumia 520).

Lumia WP8 devices come with two different types of Hardware, the high end Lumia devices (Lumia 920, 820) come with 1.5 GHz Dual Core Processor powered by Qualcomm‘s MSM8960 Chipset with Adreno 225 GPU whereas the other three Lumia WP8 devices (Lumia 720, 620 & 520) come with 1.0 GHz Dual Core Processor powered by Qualcomm’s MSM8227 Chipset with Adreno 305 GPU.

Below is the Battery Capacity of devices.

  • Lumia 920 – 2000 mAh
  • Lumia 820 – 1650 mAh
  • Lumia 720 – 2000 mAh
  • Lumia 620 – 1300 mAh
  • Lumia 520 – 1500 mAh

Before we look at results one thing we should keep in mind is that when the tests were carried out, the devices had different firmwares on them & Nokia was able to improve the battery performance with several firmware upgrades.
