How to compare battery use with animations disabled

If you want to know whether turning off screen animations makes your laptop or phone battery last longer, a quick glance at the battery percentage is not enough. The difference may be smaller than normal changes caused by screen brightness, background apps or battery reporting.

The Battery Meter shows charge level, charging state, time left and drain rate when your browser can access battery information. Compare the same activity with animations on and off, and treat the result as an estimate, not a measurement of animation power by itself.

Compare battery drain with animations on and off

1. Open the Battery Meter on the device you want to check. If the tool is not available, your browser is not reporting battery data for that device.
2. Unplug the device and start with a similar charge level for each run. Keep screen brightness, power mode, connected accessories and the apps you use the same. Avoid installing updates or changing several settings during the comparison.
3. With animations enabled, repeat one consistent activity for 20 to 30 minutes. For example, open and close the same windows or switch between the same screens at a steady pace. Note the starting and ending charge levels and the drain rate shown by Battery Meter.
4. Turn animations off using the setting for your device. On Windows 11, go to Settings › Accessibility › Visual effects and turn off Animation effects. On macOS, go to System Settings › Accessibility › Display and enable Reduce motion. On iPhone, use Settings › Accessibility › Motion › Reduce Motion. On Android, search Settings for Remove animations; the menu location varies by device.
5. Repeat the same activity for the same amount of time, then note the readings again. For a more reliable check, do another run with animations back on. Comparing on, off, then on helps reveal whether a changing background condition affected your result.

Keep Battery Meter open in the same browser during each run, but make sure your comparison activity actually uses animations. Leaving the device idle with the test open does not show much about the energy used by animations that are not happening.

What the result means

The drain rate is lower with animations off

This run is consistent with lower battery drain, but it does not prove that animations caused the entire difference. A background task may have finished, the device may have cooled down, or the battery estimate may have shifted. If the on, off and on runs show the same pattern, the result is more convincing.

The drain rate looks about the same

The comparison did not show a clear change under this workload. That does not prove animations use no energy. Their effect may be too small to distinguish from normal variation, especially if animations happen only briefly during your usual use.

The drain rate is higher with animations off

Do not assume that disabling animations uses more power. Check whether the device was doing more background work, running hotter, or at a different brightness during that run. Repeat the comparison with the same activity and conditions before drawing a conclusion.

Keep the comparison fair

Battery Meter reports a drain rate estimate and a charge percentage, not the energy used by a particular feature in watts or watt-hours. Battery percentages can be rounded, and a short test may show little or no movement. If the displayed rate changes a lot from moment to moment, compare the full 20 to 30 minute runs rather than relying on one instant reading.

Use the same screen, app, actions and timing each time. Do not compare a quiet idle period with a busy period full of scrolling and window changes. Also keep brightness steady: the display can affect battery use much more than occasional transitions, so a brightness change can hide the result you are looking for.

What the animation setting can and cannot change

The operating system's animation option may reduce transitions and motion effects, but it does not necessarily turn off every animation inside every app. An app can have its own animation setting, and animated video or other moving content may continue to play.

Battery Meter is available only on devices whose browser reports a battery, such as some laptops, tablets and phones. If the tool is missing, or it does not show useful readings, the browser may not expose that information. Restore the animation setting after your test if you prefer the original look and motion.
