Microsoft has given the Surface Pro 2 a firmware upgrade that reportedly boosts the device's battery life by nearly 25%.
According to tech website Anandtech, the update allows the device's Marvell Wi-Fi chip to consume less power, allowing it to perform considerably better under certain tests.
It ran multiple tests with the Surface Pro 2's screen calibrated at 200 nits brightness. In a general battery test, it managed to last 8.3 hours before giving up the ghost, compared with the six and a half hours it achieved pre-update. The Verge also saw a 20% improvement in battery life.
Longer legs
Anantech's video test found a 16% improvement after the update was applied, with the machine going for 7.73 hours versus 6.65 hours running the old firmware.
Microsoft launched the Surface 2 and Surface Pro 2 on October 22. It's worth noting that the ARM-based Surface 2, which runs Windows RT, has not been so fortunate as to also receive a firmware update.
As such, Anandtech found that the Surface Pro 2 has leapfrogged the Surface 2 in terms of battery life after the update, giving you one less reason to plump for Microsoft's struggling< /a> Windows RT slates.
