The ASUS ExpertBook P3 G1 is a capable business laptop if your workday rewards responsive performance, a comfortable keyboard, useful ports, and upgrade options more than long unplugged stretches. The 14-inch Intel Core Ultra 7 255H unit reviewed by TechPP has a 50 Wh battery, and its reviewer estimated about 8–9 hours of basic use. That is a meaningful qualification to ASUS’s separate claim of up to 19 hours for a 16-inch G1 configuration with a 70 Wh battery.
What did TechPP review?
TechPP’s 2026 review concerns the 14-inch ASUS ExpertBook P3 G1 with an Intel Core Ultra 7 255H processor. The reviewed unit has a 50 Wh, three-cell battery, a 1080p FHD IR camera with Windows Hello and a privacy shutter, and a keyboard with 1.5 mm of key travel. The reviewer also reports two SO-DIMM memory slots and two M.2 slots.
Those details are specific to the review unit, not a guarantee for every laptop sold under the P3 or P3 G1 name. For example, ASUS Malaysia lists a 14-inch Intel model, P3406CCAP-LY5150WS, part number 90NX0AM1-M008W0, with a 70 Wh battery, 512 GB PCIe 4.0 NVMe SSD, and a 65 W USB-C adapter. Its screen is a 1920 × 1200 WUXGA 16:10 panel rated at 300 nits. That regional listing is not proof that TechPP tested the same SKU. Check the exact model and regional specification before buying.

How long does the battery last?
For the 50 Wh Intel review unit, TechPP reviewer Ramesh Reddy reports about 8–9 hours of basic use and 4–5 hours during medium-to-heavy gaming. These are reviewer-observed estimates, not results from a stated standardized test, so treat them as a rough guide rather than a guaranteed runtime. Demanding workloads and gaming are a poor match for anyone who needs a full day away from an outlet.

ASUS’s product page tells a different, configuration-specific story: its 16-inch Intel G1 listing specifies a 70 Wh battery and advertises up to 19 hours. ASUS qualifies that figure: actual runtime varies with configuration, use, operating conditions, and power management, and battery capacity decreases over its lifetime. The same page says the laptop can reach 65% charge in 49 minutes under controlled conditions; charging time can vary. These manufacturer figures should not be read as measurements of the 14-inch TechPP review unit. ASUS’s 16-inch ExpertBook P3 G1 page
Other published runtime figures cannot settle which configuration lasts longest in ordinary work because the machines and test procedures differ:

| Source and configuration | Test conditions | Reported runtime |
|---|---|---|
| TechPP, 14-inch Intel Core Ultra 7 255H G1, 50 Wh, 2026 review | Reviewer’s basic-use estimate; no controlled protocol described | About 8–9 hours basic use; 4–5 hours medium-to-heavy gaming |
| PCWorld, AMD Ryzen AI 7 350 configuration, 70 Wh | Repeated 4K local-video playback in Windows 11, airplane mode, 250 nits, until suspend | 768 minutes (12.8 hours); PCWorld cautions ordinary use will be shorter |
| ITPro, AMD review unit, 70 Wh | Looping-video rundown at 170 cd/m² | 16 hours 27 minutes |
| ASUS, 16-inch Intel G1 product-page claim, 70 Wh | Manufacturer estimate; actual results vary by configuration, workload, conditions, and power management | Up to 19 hours |
The AMD results are context, not a head-to-head comparison with the Intel G1: they use a different P3 configuration and video-loop methods rather than the same everyday workload. PCWorld’s controlled result is described in its ExpertBook P3 review; ITPro explains its test in its ExpertBook P3 review.

Comfortable typing and practical connections
TechPP praises the 1.5 mm-travel keyboard and the selection of connections. The review lists Thunderbolt 4 USB-C, another full-function USB-C port, USB-A, HDMI, Ethernet, and a 3.5 mm audio connection. That assortment can reduce the need for adapters at a desk or in a meeting room, although the precise port complement should be verified against the SKU you are considering.

Room to expand
The review unit’s dual SO-DIMM and dual M.2 slots give businesses a route to expand memory or storage instead of replacing the whole machine. The TechPP report does not establish which capacities or aftermarket parts are compatible with every regional configuration, so confirm the exact model’s service documentation and support terms before planning an upgrade.
Performance with an AI-feature caveat
The Core Ultra 7 255H earned positive performance feedback in the review, but this should not be confused with a claim that every configuration has identical performance. TechPP reports that the tested processor’s NPU reaches up to 13 TOPS, below the threshold the review cites for Copilot+ PC features. If those specific AI features are essential, check the requirements for the feature and the exact processor rather than assuming the G1 label guarantees them.

What are the main compromises?
- Battery endurance: The 50 Wh review configuration’s basic-use estimate may be adequate for desk-based work, but its reported 4–5 hours under medium-to-heavy gaming makes it a weaker fit for sustained demanding work away from power.
- Display color: TechPP describes color coverage as poor. That is a concern for color-sensitive creative work; the review’s assessment should not be generalized to every panel option or SKU.
- Webcam: The reviewer calls webcam quality average, despite the reviewed unit’s 1080p FHD IR camera and privacy shutter. The camera’s resolution and Windows Hello support do not by themselves establish image quality.
- Heat: TechPP notes that the laptop gets warm. The review does not provide a temperature measurement, so this is a qualitative caution rather than a quantified thermal result.
Is this the right business laptop for your work?
“Which is the best laptop for business?” depends on what the business actually needs. The P3 G1 is a plausible fit for employees who value a responsive Intel configuration, comfortable typing, wired networking and display connections, and the option to expand memory or storage. It is less compelling for people whose priority is color-accurate work, consistently strong webcam quality, or long battery life under demanding loads.
Before purchase, compare the exact SKU against your requirements:

- Identify the configuration: Confirm model number, processor, screen size, display specification, battery capacity, and included charger for your region.
- Match runtime evidence to your day: Do not use ASUS’s 16-inch, 70 Wh “up to” claim as a promise for the reviewed 14-inch, 50 Wh unit. Treat the TechPP figures as estimates for that reviewer’s use.
- Check upgrade needs: Verify memory and SSD slot availability and supported capacities for the specific SKU if expansion matters.
- Choose by workload: For color-critical content work or AI features with specific hardware requirements, verify those capabilities directly rather than relying on the business-laptop name.
Also keep this G1 Intel review separate from ASUS’s earlier P3 announcement. The August 7, 2025 announcement covers AMD-based PM3406 (14-inch) and PM3606 (16-inch) models, including configurations up to Ryzen AI 7 PRO, dual-SSD expansion, fingerprint reader, TPM 2.0, and ExpertGuardian features. Those are family background, not specifications for TechPP’s Intel G1 review unit. ASUS’s August 7, 2025 announcement
