Uses for Old Phones: 10 Ideas, from Night Light to Mood Lamp
Short answer: The best uses for old phones work without a SIM card, on Wi-Fi only: webcam, security or pet camera, baby monitor app, music player, smart-home remote, alarm clock, or recipe screen. With a color filter on the flashlight LED, an old phone also becomes a night light or mood lamp. If you truly don't need it anymore: wipe your data, then donate or recycle it.
Why keep using an old phone?
Plenty of drawers hide at least one smartphone that still works. The camera, speaker, screen and Wi-Fi are often perfectly fine – it's just too slow for everyday use. For one fixed job, it's usually still good enough.
Two things first:
- Updates: If the device no longer gets security updates, use it only for simple tasks. Online banking, passwords and private chats belong on your current phone.
- Clean up: Sign out of accounts you don't need, delete apps, and install only the one app for its new job.
Uses for old phones: 10 ideas
1. Webcam for your laptop or PC
A phone camera is often sharper than many built-in laptop cameras. With a webcam app, you connect the old phone to your computer over Wi-Fi or USB – handy for video calls and online classes.
2. Security or pet camera
With a camera app, your old phone becomes a live camera for the hallway, your pet, or the garden shed. Important: only film your own rooms, tell roommates and guests, and never point the camera at neighbors' property or public paths.
3. Baby monitor app
Two phones plus a baby monitor app give you a simple baby monitor with audio and often video. To be honest: a dedicated baby monitor is the more reliable long-term option, because the app depends on Wi-Fi and the phone. For vacations or a visit to grandma, the app is a good backup.
4. Music player
Save music offline, connect a Bluetooth speaker, done. Great for the kitchen, workshop or workouts, or for kids who want to listen to audiobooks – without access to chats and the browser.
5. Smart-home remote
If you use smart-home devices, smart speakers or a streaming stick, the old phone becomes a dedicated remote. On the wall or the coffee table, the whole household can use it without grabbing their own phones.
6. Distraction-free alarm clock
Alarm app on, airplane mode on. On most devices the alarm still rings, but no notifications bother you at night. Your new phone can stay outside the bedroom.
7. Recipe screen and e-reader
In the kitchen, the old phone shows recipes so your main phone stays clear of doughy fingers. With a reading app, it also becomes a small e-reader for the commute or your reading corner.
8. Mood lamp with colored light
This is where Flashy Hue comes in. A Flashy is a 7 mm stick-on color filter for the flashlight LED. It gives the old phone a second chance as a lamp:
- Clean the LED.
- Peel the Flashy off the carrier card.
- Stick it on the center of the LED.
- Turn the flashlight on and aim it at a light wall or ceiling.
For dreamy light, pick Fairy Lights (Power Pink, Mystic Violet, Sky Breeze in turquoise). One or two phones on a shelf are enough to fill the room with pink, violet or turquoise.
9. Night light and flameless candle-like glow
Warm tones feel cozy in the evening: Sunset Lights (Flame Red, Solar Orange, Royal Gold) turn the old phone into a soft guiding light for the hallway or nightstand. Royal Gold gives a golden, candle-like glow – step by step in flameless candle light with an old phone. Honestly: for finding your keys, white light is brighter. Turn the flashlight off when you no longer need it.
10. Donate or recycle
If none of these fit, give the phone a second life with someone else. Many charities and collection points take old phones, and many recycling centers and electronics retailers take old devices back. Phones don't belong in household trash.
Before you hand it over: back up your data, sign out of all accounts (including turning off device location tracking), reset to factory settings, and remove the SIM and memory card.
Which idea fits you?
| Your goal | Best idea | What you need |
|---|---|---|
| Look better on video calls | Webcam | Webcam app, Wi-Fi or USB |
| Keep an eye on home or pet | Security camera | Camera app, Wi-Fi |
| Music without distractions | Music player | Offline music, Bluetooth speaker |
| Calmer nights | Alarm clock | Alarm app, airplane mode |
| Cozy light in your room | Mood lamp | Fairy Lights or Sunset Lights |
| Get rid of it for good | Donate or recycle | Factory reset, SIM out |
A Flashy fits all smartphones, iPhone or Android. If your old phone has a large LED ring (about 3 cm), stick on several Flashys – every pack contains several filters. Flashys peel off without residue. Want several old phones glowing in the same color? Grab the Friends Pack (five Flashys in one color, e.g. Ocean Blue in deep blue or Emerald Green). For the basics of colored phone light, see the guide How to change your phone flashlight color.
Quick safety note: Never look straight into the LED and never shine it into anyone's eyes. Flashys are small 7 mm parts – keep them out of reach of small children.
