Do these 3 things before closing this tab:
1Scan for outdated or missing drivers - takes under a minute2Repair Windows errors before they cause bigger problems3Fix the driver behind crashes, sound loss and screen glitchesTo get more time between charges, start by lowering screen brightness and shortening screen timeout, then check Battery usage for apps that are draining power in the background. Battery Saver, less-unneeded connectivity, and keeping the tablet cool can also help. Settings and feature availability vary by manufacturer and Android version, so search Settings for “Battery” or “Battery usage” if a menu path differs.
Which settings should you change first?
Reduce screen brightness and screen-on time
The display can use substantial power while you watch video, play games, read, or leave the screen on. Lower brightness to a comfortable level, and shorten the screen timeout so the display turns off sooner when you stop using the tablet. Automatic brightness is another option if it suits your surroundings and preferences. These are sensible first adjustments because they reduce power use without restricting background app activity.

If your tablet offers a dark theme, you can try it, but the battery benefit is not guaranteed across all display types. Google’s general Android guidance recommends display adjustments as part of its battery-saving advice.
Review apps with high battery use
Open Settings and look for Battery, Battery usage, or a similarly named screen. Review the apps using the most power, especially if an app is active in the background when you are not using it. On Pixel Tablet, Battery usage can show apps that used battery in the previous 7 days or since the tablet’s last full charge; that reporting window is specific to Google’s Pixel Tablet instructions, not a guarantee for every Android tablet. Google’s Pixel Tablet battery-drain guide explains how to inspect usage and troubleshoot apps.

Restrict background activity or uninstall an app only if you do not need its ongoing work. Restrictions can delay syncing or notifications and may change how the app behaves. Avoid trying to force-stop essential system apps; some cannot be closed, and interfering with them may cause problems.
Use Adaptive Battery and Battery Saver thoughtfully
Leave Adaptive Battery, or your manufacturer’s equivalent, enabled if it is available. It can manage background activity based on your usage. For a longer stretch away from a charger, enable Battery Saver. Its trade-off is reduced background work and, depending on the tablet and mode, reduced effects, features, or connectivity. Notifications and updates may arrive later.

Connectivity, location, and hotspot use
Turn off Bluetooth or Location when you do not need them, and avoid leaving a mobile hotspot on for long sessions. If Wi-Fi is available and appropriate, Google’s general guidance suggests using it instead of mobile data. These changes are task-dependent: location-based apps may stop working correctly, connected devices may disconnect, and syncing or notifications can be delayed when connectivity is reduced.

Heat and charging habits
Keep the tablet cool. Google warns that heat can increase battery drain even when a device is idle and can damage the battery. Do not leave it in a hot place, particularly when fully charged. There is no need to repeatedly drain the battery to zero and recharge it to “train” it; Google says that full-to-empty cycling is unnecessary.

For Pixel Tablet owners who leave the device on its Charging Speaker Dock, Google documents a battery-protection feature that pauses charging at 90% while docked. Google says, “This feature helps prolong your tablet’s battery lifespan.” It is a device-specific battery-protection feature, not a way to increase runtime away from the dock. Details are in Google Pixel Tablet Help: Battery protection on your Pixel Tablet.

What to do if the tablet still drains quickly
- Check Battery usage. Look for apps with unusually high use, particularly background use, and decide whether their activity is needed.
- Restart the tablet. This is a straightforward troubleshooting step before changing more disruptive settings.
- Install available updates. Update Android and your apps, then see whether the drain continues.
- Get model-specific help. Use the manufacturer’s support instructions for your exact tablet. Google’s Pixel Tablet troubleshooting steps and menu paths do not necessarily apply to other Android tablets.
- Consider a factory reset only as a last resort. It removes apps and their associated data. Back up anything important before proceeding, and follow the manufacturer’s instructions for your model.
Google’s Pixel Tablet drain troubleshooting page includes these checks. Menu labels and feature availability vary; Google notes that some general Android steps apply only to Android 13 and later. Samsung likewise cautions that Galaxy setting names and entry points can vary by OS version, as described in Galaxy Battery – Optimization.

How to choose which changes to keep
There is no universal number of minutes or percentage of extra runtime to expect from any one adjustment. The result depends on what is using power on your tablet, and the available official guidance does not establish comparable runtime tests across these steps. Prioritize changes using three questions:
Quick Recap
- What is draining this tablet? If screen use dominates, reduce brightness and screen-on time. If a particular app is prominent, examine its background activity.
- What inconvenience is acceptable? Battery Saver and background restrictions may delay notifications, syncing, or app activity.
- Does this apply to this model and Android version? Search Settings for Battery or Battery usage, and use the tablet maker’s instructions when labels or options differ.
