1. Extend the Life of Your Devices

A well-maintained device can last years longer, saving you money on unnecessary replacements. Regular cleaning, upgrading, and proper maintenance can prevent overheating, slowdowns, and early failures.

a. Keep Your Devices Clean and Well-Maintained

Dust buildup inside laptops, desktops, and game consoles can lead to performance issues and overheating, shortening a device’s lifespan. Using compressed air to clean vents and fans every few months helps regulate temperature and maintain peak performance. Proper ventilation is also crucial—keeping your laptop elevated and avoiding soft surfaces like beds or couches prevents overheating and internal damage.

Battery health is another key factor in device longevity. Safe charging practices—such as unplugging devices when fully charged and keeping battery levels between 20–80%—can significantly extend battery life. Avoid exposing batteries to extreme heat or cold, as this can degrade performance over time. You can learn more about how to extend the life of your smartphone battery in our earlier article.

b. Replace Old Batteries Instead of Upgrading

If your phone or laptop no longer holds a charge, consider replacing the battery instead of buying a new device. Many modern smartphones and laptops allow for battery swaps, and replacing a worn-out battery is often far cheaper than an upgrade. Even if your device is labeled “non-removable,” many batteries can still be replaced with DIY repair kits or through local repair shops. For laptops, here is a quick hack that works on laptops with poor battery life without costly repairs and replacements.

2. Speed Up Your Old Devices for Free without Buying New Ones

A sluggish device doesn’t necessarily mean it’s time to upgrade. With a few free software optimisations, you can bring an old computer, phone, or tablet back to life without spending a dime.

a. Optimise Storage

Storage clutter can slow down your device, leading to frustrating performance issues. Start by clearing cache files, deleting temporary files, and uninstalling unused apps to free up space. Many computers and smartphones come preloaded with bloatware that consumes resources. Removing these unnecessary apps can instantly boost performance.

If you’re running low on space, consider offloading large files to cloud storage services like Google Drive, OneDrive, or pCloud instead of cluttering your internal storage. On Android devices, moving apps to an SD card can also help free up valuable space.

b. Boost PC/Laptop Speed with Free Software Tweaks

Computers often slow down due to background apps consuming resources. To speed up your device, disable unnecessary startup programs to reduce boot time and improve performance. If you’re using an older HDD (hard disk drive), defragmenting it occasionally can help, but SSDs should not be defragmented, as it can shorten their lifespan.

Another trick is to switch to lightweight applications—for example, using VLC Media Player instead of heavy media players or opting for a lightweight web browser like Brave or Firefox instead of Chrome. Other alternative browsers and search engine are available here.

c. Use Lightweight Operating Systems for Old Devices

If your PC or laptop is struggling with the latest version of Windows or macOS, consider switching to a lightweight operating system. Linux distributions like Ubuntu, Zorin OS, or CloudReady are designed to run efficiently on older hardware. For Android users, custom ROMs like LineageOS can remove bloatware and extend support for outdated phones.

d. Factory Reset for a Fresh Start

If your device is still sluggish after optimisations, a factory reset may be the best solution. Over time, software clutter slows devices down, and resetting your phone, tablet, or computer can clear out junk files and restore peak performance. Just make sure to back up important data first before resetting to avoid losing valuable files.

Actionable Tip: Use CCleaner (Windows/macOS) or BleachBit (Linux) to clear out junk files and optimise storage, helping your device run faster without needing new hardware.

3. Repair Instead of Replace (Fix Minor Tech Issues Yourself)

Many tech issues are minor and can be fixed at home rather than paying for expensive repairs or replacing a device altogether. With a little patience and the right tools, you can repair your own devices and save a significant amount of money.

a. Fix Minor Issues at Home

Common problems like cracked screens, loose charging ports, and frayed cables are often repairable with simple DIY fixes. Instead of tossing out a damaged device, consider using screen replacement kits, soldering tools, or adhesive solutions to restore functionality. Loose charging ports can often be cleaned with compressed air or repaired with small adjustments using a toothpick or needle.

Thanks to online resources, repairing your own tech has never been easier. Websites like iFixit and YouTube offer step-by-step guides to fix common problems, such as replacing a phone battery, upgrading laptop RAM, replacing SSD or fixing a broken screen. Many repair kits available online include screwdrivers, pry tools, and suction cups, making self-repair accessible for beginners.

c. Salvage and Reuse Parts

Even if a device is beyond repair, you may be able to salvage useful components. An old laptop hard drive can be converted into external storage using an inexpensive USB adapter or Enclosure, while phone screens and batteries can often be repurposed for other projects.

Actionable Tip: Buy an affordable repair kit (screwdrivers, pry tools, adhesives) for under $20 to start fixing devices yourself. It’s a one-time investment that can save you hundreds on future repairs.

4. Avoid Unnecessary Tech Upgrades

Upgrading every year just because a new model is released is an expensive habit. Most devices remain functional for years with proper care, so avoiding impulsive upgrades saves money and reduces electronic waste.

a. Skip Yearly Phone Upgrades

Smartphone companies market their latest models as must-have innovations, but the truth is, most new features are incremental. If your phone is still working well, holding a charge, and running smoothly, there’s no reason to replace it. Instead, consider:

Replacing the battery if it no longer holds a charge.
Resetting the device to clear out sluggish software.
Updating the operating system to get security patches and performance improvements.

b. Buy Refurbished or Second-Hand Instead of New

If you must upgrade, buying refurbished can save you 30-50% compared to new models. Certified refurbished devices from Apple, Samsung, or Dell Outlet often come with warranties and guarantees, making them a cost-effective alternative. Visit Amazon Renewed for expertly refurbished products backed by Amazon Renewed Guarantee for your next tech and save big.

c. Check for Trade-In Programs Before Replacing Devices

Many manufacturers (including Apple) and retailers offer trade-in programs where you can exchange old tech for credit toward a new device. This can help offset the cost of upgrading while ensuring your old device is properly recycled.

Actionable Tip: Use your phone for at least three years before upgrading to maximise value and reduce waste. Some manufacturers offer software updates up to 5 years. If it’s slowing down, consider a a backup and factory reset over buying new.

5. Get Free or Cheaper Software Alternatives

Software costs can add up quickly, but there are plenty of free and open-source alternatives that offer the same functionality without the price tag.

a. Switch from Paid to Free Software

Here are some alternatives:

Google Docs or LibreOffice instead of Microsoft Office
GIMP or Canva instead of Photoshop
DaVinci Resolve instead of Adobe Premiere Pro

b. Use Open-Source Operating Systems

If your computer is slowing down and you don’t want to pay for another Windows license, try a lightweight Linux-based OS like Ubuntu, Zorin OS, or Linux Mint. These operating systems run faster on older hardware and are completely free.

c. Find Free Music, Video, and Cloud Storage Options

Many people pay for streaming services unnecessarily when there are great free options available. For music use Spotify Free, Deezer, SoundCloud and Jango with ad-supported music streaming. YouTube has a vast collection of free music and videos. For store, check out Google Drive, OneDrive, and pCloud with free storage space.

d. Take Advantage of Free Trials and Student Discounts

If you need premium software, check for free trials and student discounts before purchasing. Many companies, including Adobe and Microsoft, offer heavily discounted or free versions for students and educators.

Actionable Tip: Use Ninite.com to install essential free apps quickly without bloatware. It automates software installation and keeps everything up to date.

6. Cut Down on Subscription Costs

Subscription services add up over time, and many people pay for unused or overlapping services without realizing it. Trimming unnecessary subscriptions can save hundreds per year.

a. Share Family Plans for Streaming and Cloud Storage

Instead of paying for individual accounts, share family plans for streaming services like AppleOne, Netflix, Spotify, and Google One. These plans cost less per person and often allow multiple users.

b. Use Free Alternatives to Paid Services

Many paid services have completely free or cheaper alternatives:

Google Docs instead of Microsoft 365
ProtonMail instead of paid email services
Dropbox Basic instead of premium cloud storage plans

c. Use Free Versions of Premium Streaming Services

Yes we mentioned this several times in this article alone but a subscription paid is a dent to your wallet. If you don’t mind occasional ads, free streaming options like Spotify Free, YouTube, and Pluto TV offer a cost-effective way to enjoy entertainment without paying monthly fees.

d. Negotiate or Cancel Unused Subscriptions

Many people subscribe to services they rarely use. To cut unnecessary spending start by auditing your subscriptions and cancel those you don’t need. Negotiate a lower price—some services offer discounts if you ask or try to cancel. Use tracking apps like Trim or Rocket Money to monitor and manage recurring payments.

Actionable Tip: Set reminders before free trials end to avoid auto-renewal charges. If you don’t plan to continue a service, cancel it right after signing up to prevent forgetting later.

7. Repurpose Old Tech Instead of Buying New

Before discarding old gadgets, consider repurposing them for new uses. Many outdated devices can serve practical purposes, saving you from buying new equipment unnecessarily.
