Battery life is one of the most important things people check before buying a tablet. A tablet is often used for watching videos, browsing the internet, working on documents, attending online classes, or even gaming. All these activities drain power at different rates.
The strength of the battery is not just about the size in milliamp hours (mAh), but also about how well the screen, processor, and software are optimized to save energy. In 2025, brands are trying hard to balance large batteries with powerful hardware and bright displays.

Samsung Galaxy Tab S11 Ultra is the best tablet with a long battery life. The device is equipped with a massive 11,600 mAh battery along with a bright Dynamic AMOLED 2X display. It uses one of the latest processors, which balances power and efficiency. The big screen and high refresh rate do demand a lot of energy, but the large battery ensures the tablet can last long under mixed use, such as streaming, note-taking, or gaming.

Samsung Galaxy Tab S11 boasts an 8,400 mAh battery. The device does not match the Ultra in size, but it offers better portability and lower power consumption thanks to the smaller screen.

Galaxy Tab S9 line remains among the most trusted names for battery life. Tab S9 Ultra is equipped with about 11,200 mAh, while Tab S9+ has around 10,090 mAh. Even the smaller Tab S9 FE models manage close to 8,000 to 10,000 mAh, depending on the version.
What makes them last so long is the combination of large batteries with very efficient 4-nanometer chipsets. For light use, such as reading or watching videos at medium brightness, these tablets can last an entire day without recharging.

Redmi Pad Pro is a mid-range tablet with a strong focus on value. The model features a large 10,000 mAh battery and supports 33-watt fast charging. The 12.1-inch display runs at 120 Hz, which can consume more power, but the overall optimization allows it to perform very well in daily tasks.
The device is perfect for multimedia and video streaming. For heavy gaming sessions, the battery drains more quickly, but casual users will find it reliable for extended periods of use.
Another recent release is Samsung Galaxy Tab S10 Lite, which boasts an 8,000 mAh battery and comes with an S Pen in the box. The tablet is designed for those who need a mix of productivity and entertainment at a more affordable price point.
A more budget-friendly option, Galaxy Tab A11, features a smaller 5,100 mAh battery. While the device cannot match premium tablets, it performs decently for light use such as e-books, browsing, and online learning.
Battery size tells only part of the story. The way the tablet is used matters most. Watching videos at full brightness or gaming on high graphics will drain power faster than browsing the web or reading documents. Refresh rates also matter: 120 Hz looks smooth but uses more power than 60 Hz. Wi-Fi connections generally use less energy compared to mobile data.
Charging speed is another factor to consider. Some tablets with huge batteries may take longer to charge, while others come with fast-charging technology that saves time.
