Office laptops 2026 compared: this should be the standard battery life today
Schenker Connect 15 in the Wi-Fi test: just 6.6 hours of runtime
The Schenker Connect 15 (our review) lasts around 6.6 hours without power in our Wi-Fi test. Is that still acceptable? After all, there are now ARM-based models that can run for 24 hours without needing a power outlet. And newer x86 devices are working hard to catch up. But what does the target battery life for business laptops look like in 2026?
Comparison of the last 10 office laptops: who lasts the longest?
To find out, we compare the battery life of the 10 most recently tested office notebooks. To find out, we compare the battery life of the 10 most recently tested office notebooks. We use our Wi-Fi test as the baseline. In this test, the display brightness is reduced to 150 nits, and a script makes the browser load various changing websites, sometimes including video content.
The comparison shows: the Schenker Connect 15 (E26) has the shortest battery life of all office laptops tested this year in the Wi-Fi test. The average in the office class, measured across all devices and not just the last 10, is close to 13 hours. Our Connect 15 only manages about half of that and is therefore a clear runtime loser among current office laptops.
Among the last 10 devices, however, there was none that lasted 24 hours in the test. The top performer is the Lenovo ThinkPad T14 Gen 7 with 18 hours. The Lenovo ThinkPad T16 Gen 5 (15.8 hours), the Asus ExpertBook Ultra (16.1 hours), and the HP EliteBook 6 G1q 14 (15.9 hours) also perform very well. Only the EliteBook 6 uses an ARM processor, while the other two also achieve strong runtimes with Intel or AMD CPUs.
55 Wh or more: what role does battery size play?
However, the bar chart comparison and its labels below also show that battery size alone cannot explain the Connect 15’s result. Its battery capacity is 55 Wh. That is below average, and five competitors have a similar battery size. The HP 255 offers only 41 Wh, yet lasts almost 2 hours longer than the Connect.
Conclusion – under 10 hours gets tight in 2026
Looking at the last 10 office devices we tested this year, a pattern emerges: current office laptops should reach at least 10 hours in our Wi-Fi test. That would still place a laptop below the overall average. In particular, the Schenker Connect 15 is not well positioned here despite its standard battery. Schenker should optimize the idle power consumption that we criticized in the review, because in theory more runtime should be achievable from the battery and the efficient processor.
