Is your phone acting strange? Learn 8 clear signs your Android or iPhone may be hacked, and what to do to secure it in 2025.
You pick up your phone, and something feels off — the battery drains too fast, data disappears, or strange apps appear from nowhere. Don’t panic yet! Many people experience this in 2025, especially with rising online scams and spyware apps.
Here’s how to spot a hacked phone and what to do immediately.
1. Battery draining faster than usual
Hackers often install background apps that secretly send data. If your battery suddenly can’t last half a day, check which app is eating the most power under Settings → Battery usage.
2. Your phone feels hot even when idle
Background spy apps keep your processor busy — heat is a big red flag, especially if you’re not using the phone.
3. Unrecognized apps or icons
Go through your app drawer. If you find apps you never installed (often with blank icons or strange names), uninstall them right away.
4. Data usage spikes
Monitor data under Settings → Network → Data usage. Spyware and malware constantly upload info — you’ll see spikes even when you’re not online.
5. Pop-ups and ads everywhere
Too many random pop-ups, especially outside browsers, signal adware infection.
6. Messages or calls you didn’t send
Friends saying they received weird messages from you? That’s a common symptom of a hacked WhatsApp or SMS app.
7. Slow performance
A phone crawling suddenly, despite enough storage, means malware could be using your resources.
8. Google or Apple account alerts
Check your email — login alerts from unknown devices are a warning.
What to do now
-
Delete suspicious apps.
-
Change all passwords immediately.
-
Run a full scan using Google Play Protect or a trusted antivirus (Avast, Kaspersky, or Bitdefender).
-
Reset your phone if symptoms persist.
-
Avoid clicking random links or installing APKs from untrusted sites.
Pro tip: Enable two-factor authentication (2FA) for Google, Apple, and WhatsApp.
