The unit, shown at CES in January, used a variable refresh LCD designed to lower power draw, with idle consumption measured as low as 1.5 watts. If replicated in real-world use, this result would exceed the battery runtime Notebookcheck has recorded from most MacBook and Windows machines since it began the test in 2014. The measurement highlights a convergence of chip, panel and system integration that may shift expectations for laptop endurance.<\/p>\n<h2>Key Takeaways<\/h2>\n<ul>\n<li>Notebookcheck recorded roughly 26.9 hours of continuous web browsing on the Dell XPS 16 configuration with Intel Core Ultra 325 and an LG 1\u2013120Hz LCD using a 70Wh battery.<\/li>\n<li>Measured idle power for that laptop fell to about 1.5 watts, a notably low figure for a 16\u2011inch system and a major factor in the long runtime.<\/li>\n<li>That 70Wh Dell result outperformed every MacBook\/MacBook Pro Notebookcheck has tested and ranks ahead of nearly all laptops in this suite since 2014, with only two prior machines scoring better.<\/li>\n<li>Of the two better results, one relied on a Qualcomm Snapdragon X Plus SoC and an 84Wh pack with a 60Hz screen; the other used two batteries totalling 149Wh and a 60Hz display.<\/li>\n<li>LG Display says it is mass\u2011producing the 1\u2013120Hz Oxide LCD panel, and plans an OLED mass\u2011production version in 2027; Intel has also announced work with BOE on 1Hz capable panels.<\/li>\n<\/ul>\n<h2>Background<\/h2>\n<p>At CES in January, several PC makers demonstrated laptops that pair new low\u2011power processors with variable refresh displays intended to reduce panel energy draw. Variable refresh rate (VRR) panels can scale from very low frequencies \u2014 in some cases down to 1Hz \u2014 up to high refresh rates such as 120Hz, trimming display power whenever motion is minimal. This approach has already been used in phones and smartwatches to cut screen energy usage, and OEMs have been pushing it into larger notebooks to improve battery life without sacrificing peak responsiveness.<\/p>\n<p>Notebookcheck is a long\u2011running independent testing outlet that began a standardized Wi\u2011Fi web browsing battery test in 2014; the dataset is frequently cited when manufacturers or reviewers compare endurance. Historically, long runtimes in that test have come from two strategies: highly efficient ARM\u2011based SoCs with moderate battery capacity, or simply very large battery packs on Intel\/AMD systems. The Dell configuration in question instead combines mid\u2011sized capacity (70Wh) with aggressive power management at the component level.<\/p>\n<h2>Main Event<\/h2>\n<p>Notebookcheck evaluated a Dell XPS 16 sample fitted with Intel\u2019s Core Ultra 325 (Panther Lake family) and an LG Display 1\u2013120Hz LCD. Under the site\u2019s Wi\u2011Fi browsing workload, the unit logged nearly 27 hours of runtime. The review highlighted exceptionally low idle power draw \u2014 measured at about 1.5W \u2014 which materially extended the total test duration on a 70Wh battery pack.<\/p>\n<p>At CES, Dell had shown a higher\u2011resolution OLED option for the same XPS 16 chassis; Notebookcheck\u2019s longest result came from the 1920\u00d71200 LCD, without OLED or touchscreen features enabled. The trade\u2011off is clear: to reach the record runtime, buyers must accept a lower\u2011resolution, non\u2011touch LCD configuration rather than the premium OLED alternatives.<\/p>\n<p>While Dell is the system integrator that brought this particular combination to market, the underlying panel technology is produced by LG Display and described by the company as the first mass\u2011produced 1\u2013120Hz Oxide LCD. Intel\u2019s collaboration with panel makers \u2014 including BOE \u2014 indicates the capability is not limited to a single vendor, suggesting other makers could offer similar endurance in coming models.<\/p>\n<h2>Analysis &#038; Implications<\/h2>\n<p>Technical convergence is the core reason this result matters. Historically, battery life gains came from either very large cells or a switch to ARM architectures; here, incremental improvements in display efficiency, tighter SoC power gating and system firmware produce a substantial endurance gain without drastically increasing battery size. If manufacturers adopt similar low\u2011frequency LCDs and tune platform power management, 16\u2011inch clamshells could regularly reach multi\u2011day light\u2011use runtimes in lab tests.<\/p>\n<p>For consumers, the finding reframes purchase trade\u2011offs. Buyers who prioritize endurance may choose lower\u2011resolution LCDs and non\u2011touch options to maximize runtime. That may create product tiers where OLED and touchscreen remain premium features with explicit battery penalties, while long\u2011life models emphasize efficiency over pixel count or touch capability.<\/p>\n<p>For competitors such as Apple and Qualcomm, the result signals pressure to accelerate their own display and platform optimizations. Apple has already used low\u2011frequency displays in watches and phones, and Qualcomm has promoted Snapdragon platforms for excellent mobile power characteristics; the new combination of Intel silicon and advanced LCDs shows cross\u2011ecosystem innovation can still shift the endurance leaderboard.<\/p>\n<h2>Comparison &#038; Data<\/h2>\n<figure>\n<table>\n<thead>\n<tr>\n<th>Device (sample)<\/th>\n<th>SoC<\/th>\n<th>Battery (Wh)<\/th>\n<th>Panel<\/th>\n<th>Notebookcheck Wi\u2011Fi Result<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Dell XPS 16 (test unit)<\/td>\n<td>Intel Core Ultra 325<\/td>\n<td>70<\/td>\n<td>LG 1\u2013120Hz Oxide LCD (1920\u00d71200)<\/td>\n<td>~26.9 hours<\/td>\n<\/tr>\n<tr>\n<td>Qualcomm\u2011based top result<\/td>\n<td>Snapdragon X Plus<\/td>\n<td>84<\/td>\n<td>60Hz LCD<\/td>\n<td>Reportedly longer than many entries (Notebookcheck top performer)<\/td>\n<\/tr>\n<tr>\n<td>Dual\u2011battery contender<\/td>\n<td>Unspecified<\/td>\n<td>149 (two batteries)<\/td>\n<td>60Hz LCD<\/td>\n<td>Higher runtime driven by large capacity<\/td>\n<\/tr>\n<\/tbody>\n<\/table><figcaption>Notebookcheck\u2019s Wi\u2011Fi test emphasizes runtime under controlled browsing workloads; only values reported in the public test notes are listed above.<\/figcaption><\/figure>\n<p>While the Dell sample posts a striking hours\u2011per\u2011Wh ratio, the table shows two different paths to long runtimes: architectural efficiency (Qualcomm) and sheer capacity (149Wh dual battery).

When displaying static pages or documents, a 1Hz refresh means the panel updates once per second instead of dozens or hundreds of times, cutting the display\u2019s contribution to power draw. For laptops, where the screen can be one of the largest power consumers, lowering the refresh rate during light tasks produces meaningful gains in overall battery life. Software coordination \u2014 the OS, browser and GPU drivers \u2014 must support low refresh rates to realize the savings.<\/p>\n<\/details>\n<\/aside>\n<\/h2>\n<h2>Unconfirmed<\/h2>\n<ul>\n<li>Whether mainstream retail units will consistently match Notebookcheck\u2019s nearly 27\u2011hour result in repeated, independent tests is unconfirmed; lab runs can vary with firmware revisions and driver builds.<\/li>\n<li>The extent and timing of adoption by other OEMs beyond Dell is unclear, despite Intel and LG\/BOE announcements; broad market rollout timing is not confirmed.<\/li>\n<li>Real\u2011world continuous usage (multitasking, video, brightness changes) will almost certainly yield lower runtimes than the controlled Wi\u2011Fi browsing test, but the precise real\u2011world gap for this configuration is not quantified.<\/li>\n<\/ul>\n<h2>Bottom Line<\/h2>\n<p>The Notebookcheck measurement suggests that combining a mid\u2011sized battery with highly efficient platform components \u2014 notably a 1\u2013120Hz Oxide LCD and Intel\u2019s Core Ultra 325 \u2014 can deliver endurance previously associated only with very large batteries or ARM\u2011based designs. That shift matters because it shows mainstream x86 laptops can grow dramatically more efficient without resorting to atypically large cells.<\/p>\n<p>Readers should treat the result as a strong technical signal rather than definitive proof of everyday performance. Expect OEMs to offer clear configuration guidance: if battery life is the top priority, choose the lower\u2011res non\u2011OLED LCD and non\u2011touch model. Over the next 12\u201324 months, adoption of similar panels and firmware tuning could make long lab runtimes more common across the PC market.<\/p>\n<h2>Sources<\/h2>\n<ul>\n<li><a href=\"https:\/\/www.theverge.com\/tech\/901155\/dell-xps-16-best-battery-lg-display-1hz-panther-lake-intel\" target=\"_blank\" rel=\"noopener\">The Verge \u2014 Dell XPS 16 test report and analysis<\/a> (technology journalism)<\/li>\n<li><a href=\"https:\/\/www.notebookcheck.net\/\" target=\"_blank\" rel=\"noopener\">Notebookcheck \u2014 lab battery testing and results<\/a> (independent testing\/tech media)<\/li>\n<li><a href=\"https:\/\/www.lgdisplay.com\/\" target=\"_blank\" rel=\"noopener\">LG Display \u2014 Oxide 1Hz panel announcement<\/a> (manufacturer announcement)<\/li>\n<li><a href=\"https:\/\/www.intel.com\/\" target=\"_blank\" rel=\"noopener\">Intel \u2014 public statements on display partnerships (BOE collaboration)<\/a> (manufacturer announcement)<\/li>\n<\/ul>\n<\/article>\n","protected":false},"excerpt":{"rendered":"<p>Lead: Notebookcheck\u2019s recent laboratory Wi\u2011Fi test found a Dell XPS 16 equipped with an Intel Core Ultra 325 and an LG Display 1\u2013120Hz panel running nearly 27 hours on a 70Wh battery.
