In real-world use, the Microsoft Surface Pro 9&#8217;s battery life depends on screen brightness, refresh rate, and the applications running. User feedback indicates battery life of approximately 4-6 hours for office applications and web browsing; however, in independent testing, the Intel Core i7 version achieved approximately 9 hours and 20 minutes of&nbsp;<strong><u><a href=\"https:\/\/www.batteriesfast.co.uk\/laptop-battery\/Microsoft\/MQ20\/1747867\" target=\"_blank\" rel=\"noopener\">Microsoft Surface Pro 9 Laptop Battery<\/a><\/u><\/strong>&nbsp;life when reading at a 60Hz refresh rate.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The Surface Pro 9 supports USB-C PD fast charging, and a 65W power adapter is recommended. Using a compatible charger, it can charge to 80% in about one hour. Higher wattage chargers will not increase the maximum charging speed, but using the device while charging can improve charging efficiency. The ideal charging temperature is 25\u00b0C to 35\u00b0C.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Simplified Replacement<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">One of the most significant new features of the Microsoft Surface Pro 9 battery is the use of a screw-mounted battery instead of a glued one, making battery replacement much easier than in previous models. iFixit gave this device a repairability score of 8 out of 10, a significant improvement over previous models.
