The Core Ultra 200V Series, a new lineup of “Lunar Lake” processors that Intel unveiled earlier this month to deliver what it says is exceptional performance, breakthrough x86 power efficiency, a massive leap in graphics performance, no-compromise application compatibility, enhanced security, and unmatched AI compute, have enabled laptops that are capable of delivering nearly 24 hours of battery life, according to new tests that have been posted for the Zenbook S 14, one of the first Lunar Lake laptops from ASUS. The laptop, which leverages the Core Ultra 7 258V with 8 cores and Intel Arc graphics, lasted substantially longer in video playback versus models with older/alternative CPUs, including the AMD Ryzen 7 8845HS.
Tested systems, including their hardware configurations:
| PROCESSOR | GRAPHICS | RAM | STORAGE | |
| Asus Zenbook S 14 (2024) | Intel Core Ultra 7 258V | Intel Arc Graphics | 32GB | 512GB SSD |
| Acer Swift Go 14 (2024) | AMD Ryzen 7 8845HS | AMD Radeon 780M Graphics | 16GB | 1TB SSD |
| Acer Swift X 14 | Intel Core i7-13700H | Nvidia GeForce RTX 4050 (6GB) | 16GB | 1TB SSD |
| Asus Zenbook 14 OLED UX3405 | Intel Core Ultra 7 155H | Intel Arc Graphics | 32GB | 1TB SSD |
| Dell XPS 14 (9440) | Intel Core Ultra 7 155H | Nvidia GeForce RTX 4050 (6GB) | 16GB | 512GB SSD |
| HP ZBook Firefly 14 G11 | Intel Core Ultra 7 165H | Nvidia RTX A500 (4GB) | 32GB | 512GB SSD |
A look at the battery gains enabled by Lunar Lake:
From a report:
The efficiency of the Lunar Lake platform is meant to extend its battery life, and Intel seems to have succeeded on that front. The Zenbook lasted longer on our rundown test than any in this group, reaching nearly 24 hours. Super-long battery life supports the appeal of an incredibly portable laptop like this, so look forward to more long-lasting Lunar Lake systems.
