Battery life on Copilot+ PCs is one of the key highlights of Microsoft\u2019s campaign for the new devices. Let\u2019s confirm if these computers meet those high expectations. \u201cAll-day\u201d and \u201cmulti-day\u201d battery life are how Microsoft and Qualcomm describe a typical Copilot+ PC\u2019s battery performance. These promises caught the tech community\u2019s attention, as battery performance has eluded Windows laptops for years. However, it\u2019s best to always take marketing claims with a slice of skepticism since their numbers mostly come from favorable testing conditions. I\u2019ll be covering the real-world battery performance of Copilot+ PCs from Microsoft, Samsung, HP, Dell, Acer, Asus, and Lenovo under different usage patterns. We\u2019ll also look at how each computer performs against its manufacturer\u2019s claims and which laptop performs the best.<\/p>\n
Copilot+ PCs are a new category of Windows computers with special AI features powered by new hardware. Microsoft introduced these computers to allow users to perform AI tasks on their devices without depending on cloud servers.<\/p>\n
To make that possible, the company requires OEMs to integrate NPUs, a new type of processor specifically designed for AI computing . These NPUs must have at least 40 TOPS (tera operations per second) capabilities.<\/p>\n

Microsoft introduced a new emulation layer for Arm-based processors called Prism <\/a> to revive Windows on Arm, and it\u2019s been quite a success. It means that computers running on processors with the Arm architecture can now run x86 and x64 apps better.<\/p>\n Read more: <\/b>Microsoft Copilot+ PCs are Out Now on the Market: Do You Need One? Here\u2019s the Breakdown <\/a><\/p>\n While Microsoft\u2019s Copilot+ PC battery life claims are somewhat more conservative than Qualcomm\u2019s, both companies still put out exceptionally high numbers.<\/p>\n Qualcomm\u2019s Kedar Kondap published a blog post <\/a> on the release date of the first-generation Copilot+ PCs. The post iterated that these PCs have multi-day performance. But that\u2019s not all. The company also claimed the following:<\/p>\n Microsoft\u2019s \u201cIntroducing Copilot+ PCs\u201d blog <\/a> claimed the PCs can deliver all-day battery life and outperform the MacBook Air 15″ by 20% in local video playback. Battery life in context<\/strong>Both companies added small-print disclaimers at the bottom of each blog post. Per Qualcomm, \u201cBattery life varies significantly based on devices, settings, usage, and other factors.\u201d Qualcomm also claims to have used Microsoft Edge <\/a> for browsing, Microsoft Teams <\/a> for video call, and VLC Media Player for the video playback (4k video file) tests while setting the computer\u2019s screen at 150 nits. Part of Microsoft\u2019s footnote reads, \u201cBattery life varies significantly by device and with settings, usage, and other factors.\u201d The company also provides a dedicated page <\/a> that provides context for every Copilot+ PC claim, from performance to battery life. Microsoft also ran their video playback test at 150 nits with VLC Media Player. The video file (.mov) played in 1080p at 24 FPS. The same screen brightness was used during the web browsing test running multiple (no exact number) tabs on a browser.<\/p>\n Yes, when comparing Copilot+ PCs to other traditional computers <\/a>, the new-generation laptops offer better battery life. To be fair to Microsoft, Qualcomm, and OEMs, Copilot+ PCs deliver incredible battery performance under different scenarios. While the all-day and multi-day claims do not represent every use case and device setting, you will enjoy better numbers than Intel and AMD-powered computers. Even in real-world testing, users are saying it\u2019s the best battery performance since Microsoft\u2019s first attempt at Windows on Arm <\/a>. But these laptops offer better use cases on top of their battery performance, as x64 and x86 emulation is miles better than Windows 10 on Arm. Performance on battery is also incredible. Users say they do not have to sacrifice so much power even while running only on battery. It\u2019s not the case with x86 laptops, as you have to deal with significantly subpar performance when your computer is not plugged in.<\/p>\n As mentioned, Arm processors were originally designed for mobile devices to consume significantly less power. Here are the reasons they are better at preserving battery life:<\/p>\n While looking at what a laptop delivers on paper is good enough to influence your decision, you still have to consider the following:<\/p>\n As mentioned, the computer with the best battery life depends on the different factors covered above. While real-world tests try as much as possible to make fair comparisons, they\u2019re still not apples to apples. Things like screen panel, screen resolution, speaker output, and other specifications can drain or preserve battery life.<\/p>\n For example, an LCD screen with a higher resolution will drain more battery than an OLED screen, even if you set them to the same brightness level and run video playback (with audio) for the same number of minutes.<\/p>\n That said, it\u2019s still a good idea to see a snapshot of a computer\u2019s battery life, all things considered. That way, you\u2019ll know what you\u2019re signing up for. I\u2019ll show you the manufacturer battery life claims and real-world results from different users.<\/p>\n Microsoft released three Surface devices: Surface Pro, Surface Laptop 7 (15-inch) and Surface Laptop 7 (13.8-inch). The company claims the following battery life for each PC <\/a>:<\/p>\n Battery capacity <\/i>: 54 Wh battery<\/p>\n Battery capacity <\/i>: 66 Wh battery<\/p>\n Battery capacity <\/i>: 48 Wh (LCD); 53 Wh (OLED) According to the tests we\u2019ve seen from different reviews, the Surface Laptop 7 is one of the best battery performers. PhoneBuff\u2019s battery test for the 13.8-inch variant <\/a> involved running browsing, productivity, gaming, video calling, and video streaming sessions at different intervals. The device lasted about 7 hours during active use and lost only 4% of battery life after 16 hours on standby. A Reddit user, DifficultyWorldly502 <\/a>, revealed the Surface Laptop 7 15″ 15\u201316 hour battery life on everyday use with productivity apps, game streaming, browsing, and video playback.\u00a0 According to Mash It <\/a>, the Surface Laptop 7 13.8″ delivered about 20 hours on regular YouTube and Netflix streaming and 5 hours and 35 minutes on heavy GPU and CPU work. The Surface Pro 11 (OLED version) achieved 13 hours while streaming Netflix and YouTube and 5 hours on demanding use cases. Tom\u2019s Guide\u2019s testing <\/a> showed the Surface Pro 12 OLED version lasting 12 hours and 10 minutes on continuous web browsing. Andrew Marc David\u2019s YouTube review <\/a> also revealed the 13.8″ laptop lasted 20 hours and 9 minutes streaming 4k YouTube video at 120 Hz.<\/p>\n The Samsung Copilot+ PC is the Galaxy Book4 Edge, which comes in 16- and 14-inch versions. The company claims the 16-inch version can deliver up to 22 hours of local video playback <\/a>. However, it also issued a caveat that the number does not represent both PCs as they have different battery capacities:<\/p>\n That said, the Tech Chap\u2019s (YouTube reviewer) <\/a> real-world tests showed the Samsung Galaxy Book 4 Edge 16″ pulling off 13 hours and 49 minutes on YouTube streaming. They also lost only 2% of the battery life after leaving it overnight on standby. XDA\u2019s real-world use test <\/a> showed the 16″ lasting about 11 hours. Laptop Mag\u2019s HP EliteBook Ultra test <\/a>, which involved Wi-Fi web surfing, saw the computer hit 16 hours.<\/p>\n Asus says its new Vivobook S 15 with a 70 Wh battery lasts up to 18 hours <\/a> on local video playback. However, Wi-Fi was disabled, brightness was set to 150 nits, and the Windows power plan was set to best power efficiency to achieve that number. Real-world testing by Dave2D <\/a> revealed the following:<\/p>\n However, Notebook Check\u2019s tests <\/a> saw the following results:<\/p>\n Like other manufacturers, HP\u2019s claims <\/a> also don\u2019t reflect real-world usage, but they\u2019re not that far apart. Per the OEM, the Omnibook X (59 Wh battery) can last up to 26 hours on local video playback. The EliteBook Ultra (also a 59 Wh battery) can deliver up to 22 hours of battery life on Netflix and 12 hours of actively running Microsoft Teams. But according to Matthew Moniz\u2019s tests <\/a>, the HP Omnibook X lasted for 15 hours and 5 minutes on battery while playing video. Marshable\u2019s video test <\/a> (running a 1080p video) showed the laptop lasting 16 hours and 47 minutes. Per Notebook Check <\/a>, the HP EliteBook Ultra G1q lasts 20 hours and 22 minutes idle, 13 hours and 12 minutes on web browsing, and 2 hours and 4 minutes on heavy load with maximum brightness.<\/p>\n Lenovo\u2019s consumer Copilot+ PC is the Yoga Slim 7x. The company\u2019s battery life claim <\/a> is quite different from others, as it says the 70 Wh battery device offers \u201ctwo consecutive 8-hour days of mixed workloads.\u201d Paul Thurrot measured his uptime with the device and concluded it\u2019s best (and regular) battery performance for day-to-day work activities is just about 10 hours. According to Dave2D\u2019s tests <\/a>, the laptop can carry web browsing on battery for 11 hours and 13 minutes. Its Netflix streaming performance is 8 hours and 13 minutes. However, it lasts only 4 hours and 37 minutes under heavy load when running Photoshop.<\/p>\n I didn\u2019t get to see well-run battery life tests for Dell and Acer\u2019s Copilot+ PCs. However, the manufacturers still claim these numbers:<\/p>\n That said, from what I\u2019ve seen, it\u2019s clear the Microsoft Surface Pro 7 15″ takes the prize. The PC showed consistent performance across different tests, whether under light or heavy loads.<\/p>\n
