Android Battery Share Function

How to Use Battery Share on Android.

Ever been out and about when a friend’s phone or your wireless earbuds are about to die? If your Android phone supports it, you might be able to help with a feature called Battery Share. This lets your phone act like a wireless charging pad for other devices. I’ll show you how it works.

I’m checking this on a Sony Xperia 1V running Android 14. This feature is also commonly found on Samsung Galaxy phones (where it’s called Wireless PowerShare) and Google Pixel models. The first step is to check if your phone supports it.

Check If Your Phone Supports Battery Share

Not every phone can do this, so it’s good to check first.

The easiest way is to swipe down from the top of your screen twice to open your full Quick Settings menu. Look for a tile called “Battery Share,” “Wireless PowerShare,” or “Reverse charging.” If you see it, you’re in luck! If not, you can also check in your Settings app:

1. Open the Settings app.
2. Go to Battery.
3. Look for a Battery Share or similar option. If it’s not there, your phone might not have this capability.

How to Enable and Use Battery Share

Learn how to turn on the feature and start sharing power.

Once you’ve confirmed your phone has it, using it is straightforward.

1. Make sure your own phone has a decent amount of battery, ideally above 30%. Using this feature will drain your battery, so you don’t want to start with a low charge.
2. Swipe down from the top of your screen to open your Quick Settings.
3. Tap the Battery Share (or equivalent) tile to turn it on. You may get a confirmation message.
4. Place the device you want to charge (like another phone, earbuds, or a smartwatch) directly on the center of the back of your phone. The charging coils need to align, so you might need to adjust it a little.
5. Charging should start automatically. You’ll usually see a notification on your screen confirming it.
6. To stop charging, just remove the device from the back of your phone or tap the Battery Share tile again to turn the feature off.

Important Tips for Using Battery Share

A few things to keep in mind for the best experience.

• Remove Cases: Thick phone cases on either device can prevent charging. It’s often best to remove them for a reliable connection.
• It’s Slow: This is meant for topping up small devices in a pinch. It’s not designed for fast-charging another phone from 0% to 100%.
• Phone Will Get Warm: It’s normal for your phone to get a bit warm while using this feature.

And that’s it! It’s a super handy trick for those moments when you or a friend really need a quick power boost.
