Why you should update your phone and computer (and what happens if you don’t)

How many times has “Update available” popped up on your phone or computer… and you decided to postpone it? It’s a common reaction — many people find it annoying, slow or even unnecessary.

But the truth is simple: updates are one of the pillars of your digital security. Ignoring them can open the door to attacks, data loss and even identity theft.

1. Updates fix security vulnerabilities

• Attackers are constantly looking for “open doors” in systems.
• When a flaw is discovered, vendors release an update to patch it.
• If you don’t install it, you remain exposed to known attacks.

Real example: ransomware such as WannaCry exploited computers that had skipped basic updates.

2. They improve performance and stability

It’s not just about security — updates often bring speed improvements, bug fixes and better system stability.

• Your phone may use less battery.
• Your computer can become faster and more reliable.

3. Compatibility with new apps and services

Many apps stop working properly on older versions of operating systems.

Updating ensures access to the latest, compatible versions of your favourite apps.

4. What happens if you don’t update?

Skipping updates can lead to serious risks:

• Greater exposure to viruses, malware and online attacks.
• Loss of personal or work data.
• Theft of credentials (email, social media, online banking).
• Apps that stop working or become unstable.

5. How to update the right way

• Enable automatic updates whenever possible.
• If you prefer to update manually, set a fixed day each week to check.
• Back up your data regularly, so you’re safe in case something goes wrong during the process.

Conclusion

Updating your phone and computer isn’t a technical detail — it’s an act of personal protection. Every time you delay an update, you leave open a door someone could use against you.

Next time the notification appears, remember this: it’s quicker to install the update than to deal with the consequences of an attack.

Stay updated, stay safe.
