Your smartphone is one of the most important devices you use every day — but many people accidentally damage, weaken, or shorten the lifespan of their phone without realizing it. Avoiding a few common mistakes can dramatically extend your phone’s performance, battery health, and durability.
Here are the top 15 things you should never do to your smartphone if you want it to last longer and work better.
1. Never Use Cheap or Unknown Chargers
Low-quality chargers can overheat your phone, damage the battery, or even cause fire hazards. Always use the original charger or a certified one from trusted brands like Samsung, Anker, Baseus, or Belkin.
2. Never Charge Your Phone Overnight Every Day
Although phones have protection, keeping your battery at 100% for hours increases battery wear. Long-term, this reduces battery capacity. Unplug once it reaches 90–95% when possible.
3. Never Let Your Battery Drain to 0% Regularly
Deep discharge weakens lithium batteries. Try to keep your charge between 20%–80% for maximum battery life.
4. Never Expose Your Phone to Extreme Heat
Heat accelerates battery aging and causes performance throttling. Avoid:
- Leaving your phone in the car
- Playing games while charging
- Using thick cases that trap heat
5. Never Expose Your Phone to Extreme Cold
Low temperatures can cause fast battery drain, screen issues, and temporary shutdowns. Always keep your phone warm in your pocket during winter.
6. Never Use Your Phone While It’s Charging (For Heavy Tasks)
Gaming or filming videos while charging causes extreme heat. This is one of the fastest ways to destroy battery health.
7. Never Use Your Phone Without a Case or Screen Protector
A single drop can cost you hundreds of euros to repair. Protect your phone with a shock-absorbing case and a tempered-glass protector.
8. Never Charge Your Phone With a Dirty Charging Port
Dirt and dust cause loose connections, slow charging, and even port damage. Clean it with a wooden toothpick — NEVER metal.
9. Never Ignore Software Updates
Updates fix bugs, overheating issues, battery drain, and performance problems. Keeping your software outdated can slow down your phone.
10. Never Install Apps From Unknown Sources
Third-party APKs may contain viruses, spyware, or hidden miners that slow your phone. Only install apps from the Google Play Store.
11. Never Leave Apps Running in the Background
Background apps drain RAM, CPU, and battery. Close all apps before gaming or when your phone starts lagging.
12. Never Use Your Phone While It’s Wet
Even water-resistant phones can get internal corrosion. If your phone gets wet:
- Turn it off immediately
- Dry it with a clean cloth
- Let it air dry for a few hours
13. Never Ignore Strange Noises, Smells, or Swelling
If your battery swells, your phone becomes dangerous. Power off immediately and repair it — swollen batteries can explode.
14. Never Keep Your Phone Storage Full
If your storage is above 90%, your phone becomes slow, apps crash, and updates fail. Always keep at least 20% free.
15. Never Use Fast Charging All the Time
Fast charging is safe but increases heat. For daily use, slow charging is better for long-term battery health.
