Every year, millions of perfectly functional devices are replaced long before their time. Not because they’ve stopped working, but because performance dips, batteries fade, or small issues make them feel ‘old’. However, with a little care and a few smart habits, your tech can last years longer than you might realise.
On average, a smartphone is replaced every 2-3 years. Yet, with proper maintenance, a well-cared-for device can last up to five years, or even longer. The same goes for laptops, tablets and other devices.That’s almost double the value from the same purchase, meaning more money in your pocket and fewer gadgets ending up in landfill.
The Tech Out of Our Landfill (TOOL) campaign exists for exactly this reason: to help people make smarter choices that reduce e-waste and extend the life of the devices they already own. This guide pulls together the most effective life hacks to help you keep your tech running longer, performing better and out of the waste stream for as long as possible.
How Devices Wear Out and Why Care Matters
Each device you own is built with components that have natural limits. Batteries slowly lose their ability to hold a charge, mechanical parts loosen or wear, and software becomes more demanding with each update. But many devices still have years of life left in them – if we know how to care for them.Every extra year you keep your device working is a win for your wallet and the planet.
Battery Chemistry Basics
Most modern gadgets, from phones and laptops to wireless headphones, use lithium-ion batteries. These batteries are excellent at storing a lot of energy in a small, lightweight package, but they degrade over time. Here’s how a battery loses its charging ability:
- Charge cycles: a ‘cycle’ is a full charge from 0% to 100%, and most lithium-ion batteries are rated for 300-500 cycles before noticeable capacity loss.
- Heat: high temperatures speed up chemical reactions inside the battery, breaking down its internal structure and reducing capacity faster.
- Full/empty extremes: keeping a battery at 0% or 100% for long periods stresses the chemistry, much like over-stretching an elastic band. Staying in the 20-80% range, where possible, helps slow the decline.
Mechanical & Software Ageing
Even if your battery is healthy, other parts of your device are quietly wearing down:
- Dust and dirt can blow vents, trap heat and cause cooling fans to work harder.
- Moving parts like hinges, buttons and ports can loosen or break with repeated use.
- Updates add features and background processes that can slow performance, especially on older hardware. Without maintenance, your device feels sluggish long before the hardware is truly obsolete.
The Environmental Impact
When a device is discarded prematurely, there is an environmental cost. The world produces over 62 million tonnes of electronic waste each year, much of which contains hazardous materials that are hard to recycle.
Manufacturing a single smartphone produces an estimated 70-90 kg of CO₂, most coming from mining and processing raw materials. Extending a device’s lifespan delays that carbon cost and reduces demand for new resources.
Battery Care
Your battery is the heart of your device. Treat it well, and you can extend battery life by years; neglect it, and you’ll find yourself tethered to a charger sooner than you’d like. The good news? A few simple battery care tips can improve your device’s longevity.
Understand Your Battery
Most gadgets today rely on lithium-ion batteries. They’re powerful, lightweight and rechargeable hundreds of times – but they don’t last forever. Two key factors control their lifespan:
- Overcharging: holding a device at 100% for long periods keeps the battery at a high voltage, accelerating wear.
- Deep discharges: running down to 0% can cause voltage levels to drop so low that the battery struggles to recharge properly.
Lithium-ion batteries are happiest when kept between about 20% and 80% charge. At very high or low states of charge, the chemical reactions inside the cell put extra stress on the electrodes, which speeds up degradation.
Habits That Help Extend Battery Life
- Avoid overnight charging: leaving your device plugged in all night often means hours at 100%, which is stressful for the battery. Many modern devices include ‘optimised charging’ features – enable them to limit charge at night.
- Use manufacturer-approved chargers: cheap or knock-off chargers may deliver unstable current, causing excess heat and potential damage.
- Use slow charging: slow charging generates less heat and is gentler on the battery, ideal for routine top-ups.
- Limited fast charging: fast charging is convenient but should be saved for times when you truly need it.
- Keep devices cool: high temperatures are battery killers. Avoid leaving gadgets in hot cars, direct sunlight or next to heat sources.
- Remove cases during heavy use: some cases trap heat, so take them off when your device is working hard, e.g. heavy charging or gaming.
- Store properly for infrequent use: if you won’t be using a device for weeks or months, charge to 40-60% before storing to avoid degradation. Store in a cool, dry environment (ideally below 25°C) and avoid damp basements or hot attics.
For smartphones
Enable adaptive charging features (e.g. iOS Optimised Battery Charging, Android Adaptive Charging). Lower screen brightness and limit background apps.
For laptops
If used mostly on mains power, enable battery preservation modes offered by many manufacturers. Keep vents clear for cooling.
For tablets
Turn off Wi-Fi/Bluetooth when not needed. Avoid storing them fully charged for long periods.
For wearables
Charge little and often. Avoid draining completely, as small batteries are more vulnerable to deep-discharge damage.
Software & Storage Hygiene
A healthy battery is only half the story. To keep your device running longer, you need to keep its software lean and its storage in good shape. Over time, unused apps, bloated updates and background processes can slow even the fastest devices. The following storage management tips and performance tweaks will help keep your tech feeling fresh for longer.
1. Update Smartly
Firmware and operating system updates often include security patches, bug fixes and performance optimisations that keep your device stable and compatible with new apps.
Occasionally, major updates can slow down older hardware. Before installing, check reviews or forums to see how the update performs on your model. If an update is mostly cosmetic or feature-heavy, it may be worth holding off until any bugs are ironed out.
2. Manage Storage Space
Your device needs free space for temporary files, updates and smooth operation. When storage gets too full, performance can nosedive.
Services like Google Photos, iCloud and Dropbox can automatically back up media, freeing up gigabytes of space without losing memories.
Many apps quietly update in the background and take up valuable space. Review your app list every month and remove those you no longer need.
3. Optimise Performance
Cached data can speed up loading times, but over time, it can become bloated. Clear app caches periodically, and close apps running in the background that you don’t need.
Location services, Bluetooth and visual effects like animations can drain resources and battery life. Turn them off when not in use.
Most devices now have built-in modes that reduce performance slightly in exchange for big battery gains – ideal for extending life on busy days or when the battery is ageing.
Top Tip
Set a monthly ‘digital clean-up day’ to review storage, update essential apps and clear out digital clutter. Small, regular maintenance is far more effective than waiting until your device slows to a crawl.
Physical & Environmental Protection
Your device won’t last if it suffers from knocks, dust build-up or temperature extremes. These device maintenance tips will help you protect your tech from the outside in, ensuring that the hardware lasts as long as the software.
1. Cases and Screen Protectors
A well-designed case can prevent catastrophic drops and screen cracks without adding bulk. Look for cases with raised edges to protect the screen and camera. Tempered glass offers strong impact resistance, while film protectors prevent scratches with minimal thickness.
Some heavy rubberised cases can trap heat, which can shorten battery life and affect performance. If your device tends to run warm, especially during charging or gaming, opt for a breathable or vented design.
2. Avoid Physical Strain
Pulling the cord instead of the plug can fray cables and damage charging ports. Use a gentle grip and unplug by holding the connector.
Elevating your laptop or games console improves airflow, reducing internal heat build-up. This improves performance and extends the lifespan of fans and internal components.
3. Cleanliness Counts
- Cleaning ports and fans: use a soft brush or compressed air to remove dust from charging ports, headphone jacks and cooling vents. Avoid metal objects, which can cause damage.
- Speaker and microphone grilles: gently clean with a dry, soft-bristled toothbrush to prevent muffled audio.
- Anti-dust and anti-moisture measures: store devices in clean, dry environments and use silica gel packets in storage cases to absorb excess moisture.
4. Temperature & Moisture Management
Operating ranges:
Smartphones and tablets
0°C–35°C
Laptops
10°C–35°C
Extreme heat or cold can cause performance dips or permanent damage. Also, sudden temperature changes, like stepping indoors on a cold day, can cause moisture to form inside your device. If possible, let your device adjust gradually before heavy use.
Device-Specific Care Guides
While many maintenance habits apply to all gadgets, each type of device has its quirks and vulnerabilities.
Top Tip
The better you know your device’s unique features and limitations, the easier it is to give it the care it needs, preventing problems before they happen.

Sustainability & Responsible End-of-Life
Caring for your devices saves you money, reduces e-waste and supports tech longevity. The longer a device stays in use, the more value we extract from the resources and energy already invested in making it.
Every year we keep a gadget working is another year we delay its environmental impact.
However, even with the best care, a device will eventually reach the end of its usable life. Signs include:
- Critical hardware failure: e.g. motherboard or logic board damage that costs more than replacement.
- Security risks: the manufacturer no longer provides security updates, leaving your device vulnerable.
- Severe performance limitations: hardware is unable to run essential apps or software for your needs.
