4 ways to use your Android tablet even when the battery is completely dead.

Many people have a "death drawer" filled with old phones, cables, connectors, and sometimes even tablets. Once something is put in, it's simply taken out to be thrown away or recycled. Recently, several people have opened this drawer and found an old tablet, which had been discarded earlier because it only worked when plugged in.

 

If your tablet is too old to replace the battery or give away, you can use it as a "plug and play" smart display. This way, you can recycle a tablet with a dead battery that's been sitting there for years and is just waiting to be thrown into an electronic waste dump.

Bathroom entertainment center

 

People often avoid using their main phone while showering because steam, splashes, and slippery hands can easily damage it. Even with an IP water resistance rating, phones still contain important data that no one wants to risk. Instead, people might use their old tablet with a dead battery as a dedicated music streaming device, plugging it into a power outlet in the bathroom.

This setup relies on phone screen protectors, which are quite inexpensive on e-commerce platforms. They stick to your tablet and have suction cups for glossy surfaces. For proper use, moisten the area before applying the protector to the tablet. You'll be surprised at how strong the adhesive is.

 

Because the tablet is old, the sound quality is limited, but the small bathroom makes this acceptable. However, if you want better sound quality, consider using an affordable Bluetooth speaker with a waterproof IP rating.

Head-Up Display (HUD) for cars

Even old cars now have modern features.

Your car might be older than your tablet and lack features like a head-up display or Android Auto . Upgrading would be very expensive, not to mention the installation costs. Instead, you could use your old tablet, plugged into your car's 12V charger (since the battery is dead), to provide this functionality.

If your tablet is lightweight, use suction cups like the ones shown. For heavier tablets, consider using a vent mount or a magnetic mount with 3M VHB adhesive. These options will securely hold your tablet even on rough roads.

You can use your device as a head-up display to get information like speed and navigation, keeping essential data on display without distracting you from the road.

 

Digital receiver for analog speakers

No more need for cables running throughout the rooms.

Many people own a high-quality, old set of speakers that they really like, but they lack Bluetooth or Wi-Fi connectivity . If they're located in a different room than your desk, running a long extra cable is impractical. And while dedicated Wi-Fi music players can be expensive, old tablets offer a free solution.

 

To do this, use AudioRelay ( SoundWire is a great alternative). The process is simple: Install the server client on your Windows or Linux computer and the Android app on your tablet. Once both devices are connected to the same Wi-Fi network, open the app on your tablet and select the server name from the list.

This method is superior to standard Bluetooth in both range and quality. Wi-Fi offers greater bandwidth and coverage, so you won't experience audio interruptions when moving between devices.

Digital photo frame for your desk

Your memories will always remain.

Many people have repurposed their old Android tablets as digital photo frames on their desks when not using them as bathroom music players or car displays. Of course, you could buy a digital photo frame, but it's not recommended, as most are either too expensive or have low resolution.

That's why many people are starting to use older tablets with high-quality screens as always-on digital photo frames. In terms of software, use an app called Fotoo instead of Android's default screen saver. It connects directly to Google Photos , Dropbox , or a local server.

The standout feature here is the ability to manage schedules. For example, you can set the app to turn the screen on at 7:00 AM and off at 10:00 PM. This is important for two reasons: saving power and, more importantly, preventing screen burn-in – a common problem with older monitors when displaying static images. You'll have a high-resolution display, cloud connectivity, and self-management.
