Does Windows 11 Use More Battery Than Windows 10? (Real Test 2026)
Battery life remains one of the most important factors for laptop users. Whether you're working remotely, attending online classes, traveling, or simply using your laptop away from a power outlet, every extra minute of battery life matters.
Since Windows 11 introduced a redesigned interface, additional security features, and more background services, many users wonder whether it consumes more power than Windows 10.

Test Configuration
- Intel Core i5 Laptop
- 16GB DDR4 RAM
- 512GB SSD
- Integrated Graphics
- 50Wh Battery
- Windows 10 22H2
- Windows 11 24H2
Screen brightness was fixed at 50%, Wi-Fi remained enabled, and all tests were repeated multiple times.
Idle Battery Drain Test
Our first test measured battery usage while the laptop remained idle.
| Operating System | Battery Life |
|---|---|
| Windows 10 | 10h 25m |
| Windows 11 | 10h 05m |
Windows 11 consumed slightly more power while idle due to additional background activity.
Web Browsing Battery Test
Web browsing remains one of the most common laptop workloads.
| Operating System | Battery Life |
|---|---|
| Windows 10 | 8h 15m |
| Windows 11 | 8h 02m |
The difference was minimal and unlikely to be noticed by most users.

Video Streaming Test
Streaming video is another common laptop activity.
| Operating System | Battery Life |
|---|---|
| Windows 10 | 9h 05m |
| Windows 11 | 8h 55m |
Video playback efficiency was very similar between the two operating systems.
Office Productivity Test
We tested battery life while using:
- Microsoft Word
- Excel
- PowerPoint
- Email applications
- Cloud storage synchronization
| Operating System | Battery Life |
|---|---|
| Windows 10 | 7h 45m |
| Windows 11 | 7h 32m |
Again, the differences remained relatively small.
Gaming Battery Test
Gaming workloads produced the highest power consumption.
| Operating System | Battery Life |
|---|---|
| Windows 10 | 1h 55m |
| Windows 11 | 1h 50m |
Gaming performance was similar, but Windows 11 consumed slightly more energy.
