Frore’s December 2024 Galaxy Book4 Edge announcement tied longer battery life to a proposed increase in battery capacity. It described room for more stored energy, not a demonstrated reduction in electricity consumption.
You cannot predict runtime from the AirJet cooling inside Lenovo’s AeroBlade alone. A cooler that lets the processor work harder could increase the computer’s electrical demand. More speed, but potentially less time before you need the charger again.
Divide each advertised capacity by its accompanying runtime, and both imply an average draw of about 2.8W. The arithmetic is nearly identical. These are rough estimates from stated capacities, not measurements of energy actually delivered during a battery test.
The projected extra time follows almost exactly from the extra stored energy. It doesn't, by itself, show that AirJet makes the laptop more electrically efficient.
A larger battery would still be useful. You don't need an efficiency improvement to appreciate more hours away from an outlet. But the proposed capacity increase makes 23.2 hours a conditional claim, not independently verified endurance for a finished laptop.
Frore’s published battery figures are not consistent, either. Its separate Galaxy Book4 Edge blog describes a 53Wh battery growing to 70Wh, with 33% longer video playback. The announcement describes the smaller battery increase.
These are different starting capacities and different proposed batteries, not interchangeable estimates. The blog doesn’t reconcile them with the announcement, so combining its percentage with the announcement’s baseline would produce a runtime neither passage establishes.
Samsung’s baseline 20-hour rating uses local 1080p video at 150 nits, with wireless connections and keyboard lighting off. A downloaded movie under those conditions isn't evidence for a day of video meetings or a long rendering job.
Processor power rose about 50%. The benchmark score improved only 7.4%. More cooling allowed higher sustained power, but the measured speed gain was much smaller.
Using those figures, the score per processor watt actually fell by about 28%. This comparison describes one particular 30-minute workload, not every AirJet device or application.
Nor does the result mean battery life fell 28%. The recorded power covers selected processor components, leaving out the display, storage, cooling hardware, and other demands on the battery. A whole-laptop efficiency claim needs a whole-laptop measurement.
Cooling capacity describes how much heat a design can remove under its rated conditions. It isn't interchangeable with completed work per second, and neither figure supplies a battery runtime on its own.
The 1W figure is a maximum, not a reading for an entire working day. Multiplying it by the number of modules gives a component-level upper estimate, not measured average cooling consumption.
A fair comparison also includes whatever electricity the original cooling system used. Replacing a powered fan differs from adding active cooling to a machine that previously had none. Counting only the new cooler’s draw leaves the starting configuration out of the calculation.
For a fixed video export, the useful comparison is energy consumed until the same file is finished at identical quality settings. Finishing sooner could save energy despite higher power, but only when the time saved outweighs the extra draw.
A continuous gaming test needs a different comparison, such as matching frame rate, resolution, and graphics settings. Otherwise, the faster machine may drain sooner because it is doing more work. You would be comparing different experiences.
Equal battery capacity helps isolate whether the complete system uses less energy for the same task. A larger pack can disguise higher consumption by supplying more energy before the laptop shuts down.
A battery graph showing only percentages hides the pack’s capacity. Ten percent of a larger energy capacity represents more watt-hours. Equal percentage drops don’t necessarily mean equal electricity consumption.
The export could therefore finish faster on the AirJet machine while using more watt-hours. With a big enough battery, you might still finish more exports before charging. Longer runtime would be real, but so would the higher energy cost per finished file.

A larger battery explains the projected extra hours
Frore proposed increasing the Samsung laptop’s battery from 55.9Wh to 64.8Wh, roughly 16% more capacity. Alongside it came a projected increase in video playback from 20 hours to 23.2 hours.Divide each advertised capacity by its accompanying runtime, and both imply an average draw of about 2.8W.

Higher processor power delivered a modest speed gain
In Frore’s 2023 MacBook Air test, average combined CPU, GPU, and Neural Engine power rose from 13.18W to 19.79W. Cinebench R23 scores increased from 8,010 to 8,604.Processor power rose about 50%. The benchmark score improved only 7.4%. More cooling allowed higher sustained power, but the measured speed gain was much smaller.

Cooling power belongs in the complete battery test
Frore rates the original AirJet Mini to remove 5.25W of heat while consuming up to 1W of electrical power. Removing heat doesn't generate electricity. You cannot subtract the heat-removal rating from a laptop’s battery consumption.The 1W figure is a maximum, not a reading for an entire working day.
