There is no reliable runtime that applies to every gaming laptop: battery capacity and condition, the game, and power and display settings all matter. As one specific example, TechRadar’s 2026 review reported that an MSI Raider 16 Max HX dropped from full charge to 10% in just over two hours while playing Marathon online. That result describes one laptop and test, not a general promise.
Why gaming runtime varies so much
Games can put sustained demand on a laptop’s processor and graphics hardware, so battery life during play is different from light office work or video playback. Runtime also depends on the battery’s capacity and age, screen resolution and brightness, refresh rate, power policy, and the game’s workload. MSI lists battery capacity, Windows power plan, processor speed, storage, display resolution, brightness, and keyboard backlight among factors that affect battery life.
For a fair comparison between two runtime claims, look for the same game and workload, starting charge and stopping threshold, brightness and refresh rate, performance mode, wireless and peripheral setup, and battery capacity and age. A gaming test should not be compared directly with a manufacturer’s light-use estimate.
Settings that can reduce battery drain
These adjustments reduce power use, but they do not add stored battery capacity. Lower performance, brightness, refresh rate, or frame rate can change how a game looks or feels. The available evidence does not establish a fixed number of extra minutes for any one adjustment.

Lower screen brightness and refresh rate
Reduce brightness to a comfortable level when unplugged. If your display supports it, choose a lower refresh rate in Settings > System > Display > Advanced display. A lower refresh rate can make motion look less smooth.
Choose a more efficient Windows power mode
In Windows 11, open Settings > System > Power & battery > Power mode. Depending on the laptop, options can include Best power efficiency, Balanced, and Best performance. Microsoft describes Best power efficiency as saving battery life; choosing it can reduce performance in games.

Review background apps and graphics settings
Check per-app battery usage in Windows and close unnecessary background work. Windows also offers a Power saving graphics preference for individual apps. On a laptop with hybrid graphics, that may help non-game apps use less power; a demanding game may not perform well on integrated graphics, so do not assume this is the right choice for the game itself.
Use the laptop maker’s power profile when available
Some manufacturers offer power-saving profiles in their control software. MSI, for example, describes an Energy-Saving Mode that may lower performance to reduce consumption; the software and options vary by model. Look for the equivalent profile in your laptop’s own controls rather than assuming a feature exists on every gaming laptop.

Disconnect peripherals you do not need
Unneeded USB or Thunderbolt devices can contribute to battery discharge. Disconnect them when practical, but keep network access enabled if the game requires it.
Consider gaming endurance modes only if supported
Intel’s Endurance Gaming feature is a frame-rate and power trade-off, and Intel says the added playtime depends heavily on system design. It does not manage power on systems with discrete graphics, so it is not a universal setting for gaming laptops.

Battery health is different from runtime per charge
Battery-care features can help limit long-term wear, but they do not make a gaming session last longer on the current charge. ASUS, for example, describes Battery Health Charging and recommends about 50% charge for long-term storage, with periodic recharging while stored. These instructions are specific to the manufacturer’s products; follow the guidance for your own laptop.
