Our top picks for ultrabooks in 2026
Across battery, weight, keyboard and sustained performance tests:
Best overall: Apple MacBook Air M3 13″ — 18-hour battery, silent, best build in class
Best Windows ultrabook: Lenovo ThinkPad X1 Carbon Gen 12 — proper keyboard, 14 hours battery, business-grade
Best value: ASUS Zenbook 14 OLED — OLED display and 13-hour battery at ~£1,099
‘Ultrabook’ is Intel’s original name for thin, light, long-battery Windows laptops — the category Apple’s MacBook Air essentially invented. In 2026 the best ultrabooks combine sub-1.3kg weight, OLED displays, and 12+ hours of real battery life with enough power for serious work. We tested eight across UK university and business usage over six weeks.
The category has consolidated around three price tiers: £900-£1,100 for solid mid-range, £1,300-£1,600 for premium OLED, and £2,000+ for the absolute flagships. Our picks cover each tier plus the best value outlier.
1. Apple MacBook Air M3 13″ — Still the benchmark for everything else
Our score: 4.8/5
Six weeks later, the M3 Air remains untouched as a general-use ultrabook. 18-hour battery life, silent operation (no fan), 1.24 kg weight. The M3 chip is plenty fast for everything except heavy video editing. For most professionals this is the laptop to beat.
Pros
- 18-hour real-world battery life
- Silent — no fan means no noise
- Premium build quality designed to last 5+ years
- macOS ecosystem with excellent developer tools
- Apple resale value remains strong
Cons
- Base 8GB RAM is tight; 16GB recommended (+£200)
- Only two Thunderbolt ports
- Limited Windows-only software support
- Display is 13.6″, not 14″

Our score: 4.2/5
The XPS 13’s InfinityEdge display and aluminium-glass chassis still make it the most beautiful Windows ultrabook. Intel Core Ultra 7, 16GB RAM, 1TB SSD. The divisive ‘invisible’ function row and haptic trackpad divide opinion — you will either love them or return them. Battery life is 11-12 hours.
Pros
- Most beautiful Windows ultrabook
- InfinityEdge display looks stunning
- OLED 3K option available
- Compact footprint for 13″ laptop
Cons
- Haptic-only function row takes getting used to

The aluminium chassis is genuinely premium, and the 360° hinge is the best in class — solid in laptop mode, stable in tent and tablet.
Pros
- Excellent 2-in-1 versatility
- 2.8K OLED touchscreen
- Included active pen with tilt and 4,096 pressure
- Premium build quality
Cons

Under 1.3 kg is the weight target
A true ultrabook should be under 1.3 kg. Above 1.5 kg you are entering mid-size laptop territory where extra weight starts to cost you on transport.
12+ hours of battery is now standard
Modern ARM-based and Intel Core Ultra chips make 12+ hours of mixed-use battery achievable. Anything less than 10 hours is now a red flag in this category.
OLED is worth the premium in 2026
OLED displays are now affordable enough in this category (£1,000+) to be the default choice. The contrast, colour and deep blacks transform daily use, especially for creative work.
Check for Thunderbolt 4 ports
Thunderbolt 4 enables docking stations, external GPUs, and high-speed external storage. Every serious ultrabook in this list has at least two Thunderbolt 4 ports — avoid anything with USB-C only.
Frequently asked questions
What is the difference between an ultrabook and a laptop?
Ultrabook is a category (originally an Intel marketing term) describing thin, light, long-battery laptops usually under 1.3 kg with fanless or quiet designs. All ultrabooks are laptops; not all laptops are ultrabooks.
Can ultrabooks handle video editing?
Light to moderate video editing, yes (1080p and some 4K). For serious 4K or higher editing you want a dedicated GPU, which means a heavier creator laptop (MacBook Pro, ASUS ProArt) rather than an ultrabook.
Is Windows or macOS better for ultrabooks?
macOS on an M-series MacBook Air currently leads on battery life, silence and build quality. Windows on an X1 Carbon leads on keyboard, upgradability and port selection. Pick based on your software requirements.
Should I buy a 13″ or 14″ ultrabook?
14″ offers more screen real estate and often better cooling with minimal weight penalty. 13″ is more compact for truly mobile use. Most 2026 ultrabooks are 14″.
Do I need 32GB of RAM in an ultrabook?
For most users, 16GB is plenty. 32GB is worth it for developers running VMs, video editors, or anyone who regularly has 30+ browser tabs open. 8GB is now the bare minimum and should be avoided if possible.
How long should an ultrabook last?
5-7 years with care. Batteries will need replacing around year 4-5 (typical). Build quality of premium ultrabooks (X1 Carbon, MacBook Air, XPS) is typically excellent and chassis lasts a decade.
