How to give an old laptop and smartphone a new lease of life

An old laptop: five new roles

The most common reason why an old laptop seems useless is that it’s «slow». But before you start thinking about where to put your old laptop or whether to sell it for parts, it’s worth figuring out why: more often than not, it’s not because it’s broken or outdated, but because it’s overloaded. Dozens of background processes, a heavy operating system, and programs that start automatically — all of this eats up resources.

Optimising startup, clearing the memory of unnecessary files and installing a lightweight operating system (OS) — and the device is transformed. The hardware is the same, but the experience of using the device is completely different. This is what a basic upgrade looks like without any expense on hardware upgrades.

1. A machine designed for focused work.

If you install a lightweight operating system and keep only a text editor and a browser without any unnecessary extensions, the laptop becomes the perfect tool for note-taking, planning or studying. No notifications, no social media, no temptation to open «‘just one more tab». It sounds like asceticism, but in reality it’s simply focus — and older hardware performs brilliantly in this mode. This is particularly relevant for those who work with text, are preparing for exams, or simply want to separate their «work» and «leisure» spaces.

2. A personal home server.

A laptop sitting under a desk or on a shelf and connected to the internet can store your files, photos, videos and backups without the need for any cloud subscriptions. You get something like your own Google Drive or Dropbox — but at home, with no monthly fees and without your data being stored on third-party servers. There are handy free solutions available for setting this up that don’t require in-depth technical knowledge. If you have important documents or large photo archives, this is exactly what you should do with your old laptop.

3. A smart home control centre.

If you have smart bulbs, temperature or humidity sensors, smart sockets or climate control equipment, you can turn your laptop into a constantly active control screen for all these IoT devices. Not for work and not for gaming — just a handy display, like a thermostat on the wall, only smarter. You can view readings from all sensors, control the lighting, and run automation scenarios — all accessible in one place. The device becomes part of the interior, performs a specific function — and stops tempting you to «quickly check» your news feed.

4. A second monitor or a digital photo frame.

Few people realise that old laptops can be used as a second monitor for your main computer — this expands your workspace without having to buy an extra screen. An even simpler option is to turn it into a digital photo frame or information display: weekly deadlines, the weather, or a schedule of classes or training sessions. The device simply provides information without being distracting. It’s handy to place it in a corner of your desk or in the kitchen.

5. Home network security.

You can turn an old laptop into a filter for all internet traffic in your home. For example, the Pi-hole tool blocks adverts and trackers across all your devices at once — on your TV, tablet and phone — without having to install separate extensions on each device. In addition, you can set up your own VPN to connect securely to your home network even from public Wi-Fi in a café, hotel or airport. This is a little more technically complex than the previous options, but the result is stable and beneficial for the whole family at the same time — and you only need to set it up once.

6. A media server for the whole house.

An old laptop running Plex or Jellyfin turns into a home media centre: all your films, TV series, music and photos are accessible from any device on your home network — whether it’s a TV, tablet or smartphone. No need to copy files to a USB stick every time or search for where a particular film is stored. The laptop simply sits in a corner, running in the background and streaming content to all devices simultaneously. Set it up once — and your entire media library is always at your fingertips, without subscriptions or cloud services.

7. Retro games console.

An old laptop with an emulator is a gateway to childhood. Games from the PlayStation 1, SNES and Game Boy eras, as well as early computer classics — all of these run perfectly even on low-spec hardware, because the system requirements for such games are minimal. Plug in a gamepad, connect the laptop to the TV via HDMI — and a nostalgic gaming evening is ready without any extra expense. For children, this way of using retro laptops is a chance to discover the classics; for adults, it’s a pleasant return to their favourite games.

8. A server for learning and experimenting.

If you have a teenager in the family who’s interested in programming or technology, an old laptop is the perfect platform for risk-free experimentation. You can install different operating systems, learn how to set up a web server, take your first steps in programming, and get to grips with networks. If something breaks, just reinstall it and try again. This is the best way to learn: through hands-on practice, without the fear of damaging anything important. This option is also ideal for adults who want to acquire new IT skills.

9. Backup workstation.

Even a slow, old laptop can save the day if your main computer has unexpectedly broken down, been sent for repair, or simply needs updating at the worst possible moment. A web browser, email, video calls and basic office software are enough for most day-to-day tasks. It’s enough to keep the essential programmes installed on the device and check from time to time that everything is working. It’s better to have such a backup option ready than to find yourself without the tools you need just when it’s most inconvenient.

An old smartphone: more than just a phone in a drawer

What can you do with an old smartphone? There are far more answers to this question than you might think. An old Android smartphone has a camera, a GPS module, sound and light sensors, and a constant Wi-Fi connection. In fact, it’s a small specialized computer that simply needs to be given a new task. And before you think about disposing of old phones or selling them for parts, it’s worth trying at least one of the options below.

1. Security camera.

Probably the most popular use for an old Android device is to turn it into a CCTV camera. Apps like AlfredCamera turn an old phone into a fully-fledged camera with motion detection, night vision and live streaming. No subscription and no need to buy separate equipment. Place the device near the front door, in the hallway or point it towards the garden — and your home security system is ready. The free version stores several hours of footage, which is usually enough for basic needs.

2. Dashcam.

Using a smartphone as a dashcam is a solution that works better than many people think. Simply mount your phone on the windscreen, install the relevant app and plug it into the cigarette lighter socket to charge. The recording quality on most smartphones that are a few years old is perfectly acceptable, the viewing angle is wide, and there’s no need to buy a separate device. It’s convenient and practical — especially if your car already has a phone holder.

3. A sensor for the smart home.

Owners of Samsung smartphones can use the official Upcycling feature, available in the SmartThings app, which allows you to turn your phone into a sound or light sensor: it recognises a baby crying, a dog barking, the sound of breaking glass, and triggers the appropriate automation scenarios (for example, sending notifications or switching on specific lights). The light sensor helps control ‘smart’ bulbs depending on the brightness in the room. For other Android devices, similar features are also available via standard accessibility settings.

4. GPS tracker for a car.

The built-in GPS module turns an old smartphone into a handy tracker. For basic tracking, the standard «Find My Device» feature is sufficient. For comprehensive monitoring with a movement history and notifications about the car’s movements, specialised apps such as Life360 are ideal. The key is to leave the phone in the car connected to the cigarette lighter socket, and the device will run continuously without draining its own battery.

5. A high-quality webcam.

Even the camera in an old smartphone is often noticeably better than a laptop’s built-in webcam. Apps like DroidCam or Camo Studio connect your phone to your computer wirelessly and provide a clear image for video calls, online meetings or live streams — without having to buy a separate camera. You can place it anywhere convenient and even switch between the phone’s different lenses during a call.

6. A child’s first smartphone.

Giving your child an old phone is a far more sensible option than buying them a new device. Set up parental controls via Google Family Link, use YouTube Kids instead of regular YouTube, and restrict app installations without parental permission — and you’ll have a safe gadget where your child can watch cartoons or learn, but won’t end up where they shouldn’t. Even if the model no longer receives security updates, this is perfectly adequate for a child-friendly mode under parental supervision.

7. A portable gaming console.

If you connect a gamepad to your smartphone, it turns into a pocket-sized gaming device for retro gaming. Mobile games, retro games via emulators, cloud gaming via Xbox Cloud Gaming or GeForce Now — the power of this long-standing flagship is more than enough for all of this. Another plus is that you can safely let your child use this device without worrying about your expensive main phone.

8. Alarm clock and night light.

It might seem like a minor detail — but a dedicated alarm clock device solves one real problem: you no longer pick up your main phone before bed or immediately after waking up. Leave your old smartphone on the bedside table, set the alarms — and it will perform exactly one function, without tempting you to check your emails at 11 pm. In night mode with the brightness set to minimum, it displays the time without disturbing your sleep. It’s a simpler solution than buying a separate clock — and more effective than trying to stop yourself from scrolling through your feed before bed.

9. Control panel for equipment.

Many smartphones from a few years ago have a built-in infrared port – the very same one used by standard remote controls. This means that an old phone can control a TV, media player, air conditioner or audio system. Even if there is no infrared port, most modern devices support Wi-Fi control, and there are apps available for any device. It’s handy to keep such a «remote» in the living room or kitchen so you don’t have to hunt for the original one every time.

10. E-reader or music player.

Reading books or listening to podcasts on your main smartphone means being constantly distracted by notifications. An old phone solves this easily: install a reading app or music player, turn off all notifications — and you’ll have a dedicated device solely for relaxation. No work messages, no temptation to check social media. If the screen is still in good condition, it’s a fully-fledged e-reader that’s on a par with many specialised devices.

11. A media player for the kitchen or bathroom.

Taking your main smartphone into the kitchen whilst cooking or into the bathroom is a risk you don’t always want to take. An old phone connected to a small Bluetooth speaker becomes a fixed source of music, podcasts or radio in those places where you’d rather not take your expensive device. Set up a playlist — and it just plays, without any hassle. You can mount the phone on the wall or place it on a shelf — and it will become as much a part of the décor as a timer or a notepad.

One thing they all have in common

Most of the scenarios listed above have one thing in common: a stable home internet connection. A security camera without a connection is just a box in the corner. A home server without a network is just an expensive hard drive. A ‘smart’ home sensor without the Internet is a gadget that doesn’t work. A GPS tracker that can’t send data is a waste of battery power.

That’s why the quality of your home Internet directly affects how much real benefit you’ll get from all these solutions. Maxnet offers GPON connectivity — fibre-optic internet with consistent speeds, no slowdowns during peak hours, and reliable performance even with an unstable power supply. For scenarios where devices need to be online constantly and without interruption, this isn’t a minor detail — it’s the foundation on which everything else rests.

It’s worth understanding: technology doesn’t become obsolete just because something newer has come along. It simply waits to be given a task that matches its current capabilities. A retro laptop and smartphone are ready-made infrastructure that you already have at home, have already paid for, and which no longer requires any investment. All that remains is to decide exactly what it will do next.
