A laptop battery in sleep mode should last several days to a week, but it ultimately depends on the specific laptop and its power consumption in sleep mode. Many other factors also affect how long a laptop battery will last in sleep mode, including the laptop’s make and model, the battery’s age, and the computer’s power settings.

Some laptops may consume more power in sleep mode than others, significantly impacting battery life. If your laptop is in sleep mode and you notice that the battery drains quickly, you may want to check the power settings to ensure the computer is set to conserve power while in sleep mode. Read this in-detailed guide to resolve it.

What Happens With Our Laptop in Sleep Mode?

When a laptop is in sleep mode, it is in a low-power state, allowing it to quickly resume from where it left off. In sleep mode, the computer shuts off most of its components, like the display, hard drive, and other peripherals, but it keeps the RAM active and powered on to quickly resume operations when you wake it up.

In addition, the laptop will also continue to perform some background tasks, such as checking for updates or syncing data with other devices while in sleep mode.

This is why a laptop keeps consuming some power, although significantly less than when it is fully operational. The battery slowly discharges while the laptop is in sleep mode, albeit much slower than when it is in use. However, these tasks are typically performed slower than when the laptop is fully operational.

Laptop Battery Saving Tips in Sleep Mode

These are the most commonly used tricks to save the laptop’s battery life. If you can’t afford to spend money, leave that step and move to the next one.

Don’t let the battery go to zero percent.

Paying attention to your laptop’s battery percentage and preserving its lifespan can help ensure that your laptop remains functional and efficient for years to come. Taking the time to plug in your laptop when necessary and using power-saving settings can go a long way in keeping your laptop’s battery healthy and maximizing its lifespan.

Keep away from always plugging the charger in.

Users may keep their laptops plugged in unnecessarily or inadvertently, which can damage the battery cells and decrease battery life. Overcharging the battery can lead to a lack of backup and ultimately render the battery useless within a few weeks. To avoid this, unplug the laptop from the power source to avoid overcharging once the battery is fully charged.

Close the apps that are affecting battery health.

Closing unused apps won’t increase battery life, but it can prevent damage to the battery and improve system performance. To do so, open the start menu > search for background apps > hit enter, and you’ll see the window containing apps. The blue color indicates apps are allowed to run in the background, and the grey color means they’re not allowed.

Unplug the non-functioning peripherals.

External peripherals, such as gaming accessories, can drain a laptop’s battery and should be unplugged when not in use. Unplug all the accessories like headphones, RGB keyboards, mice, microphones, and speakers to reduce strain on the battery and conserve battery life.

Close unnecessary battery-consuming apps.

Certain office, programming, and gaming apps may continue to run even after they are closed. Press CTRL + ALT + Delete to shut them down and select Task Manager. From there, you can see all running apps and close any unnecessary programs by selecting them and pressing End Task. This can help preserve the battery life of your laptop.

Replace the hard drive with SSD and use the latest Operating System.

A laptop’s hard disk drive (HDD) can quickly drain the battery, as it uses around three disk plates to read and write data. Consider replacing it with a motherboard-fitted solid-state drive (SSD), requiring less power. Additionally, installing and using the latest operating system version can optimize battery life.
