10 Bad Charging Habits you should Avoid to protect your smartphone battery

1. Charging Your Phone Overnight

One of the most common bad charging habits is leaving your phone to charge overnight. Though convenient, this practice can lead to overcharging, causing the battery to generate excessive heat and degrade over time. Instead, charge your phone during the day and disconnect it once it reaches 100%.

2. Using Your Phone While Charging

Using your phone while it’s charging can cause the device to heat up and increase the risk of damaging the battery. To maintain optimal battery health, avoid playing games, streaming videos, or engaging in other high energy activities when your phone is connected to the charger.

3. Waiting Until Your Battery is Fully Drained

Contrary to popular belief, allowing your phone battery to drain completely before charging it is not beneficial. In fact, modern lithium ion batteries perform better when charged more frequently and maintained within a 20% to 80% range. A partial discharge helps reduce stress on the battery and prolong its life.

4. Using Cheap or Unbranded Chargers

While it might be tempting to save money by buying a cheap or unbranded charger. Doing so may come at a cost to your phone battery. Low-quality chargers may not have proper voltage regulation or safety features, leading to overcharging, overheating, or worse. Stick to using chargers from reputable brands, or better yet, the original charger that came with your device.

5. Charging Your Phone in Extreme Temperatures

Extreme temperatures—both hot and cold—can have a negative impact on your phone battery. Avoid charging your phone in direct sunlight, near heating sources, or in freezing conditions. Aim to charge your device in a cool, dry environment to help maintain its performance.

6. Ignoring Battery Percentage Alerts

Most phones have built in alerts to notify you when the battery level drops below a certain percentage, usually around 20%. Ignoring these alerts and continuing to use your phone until the battery is completely drained can put unnecessary stress on the battery. Instead, plug in your phone when you receive a low battery notification.

7. Fast Charging Your Phone All the Time

While fast charging can be a lifesaver in certain situations. It can also generate more heat and stress on your battery, compared to slower, standard charging methods. If possible, reserve fast charging for emergencies and use a regular charger the rest of the time.

8. Charging Your Phone with a Phone Case On is a bad charging habit

Some phone cases can trap heat, causing your device to become warm during charging. To avoid this, remove your phone case before charging, especially if you notice your device is getting hot. This will help prevent heat related battery damage.

9. Using Wireless Chargers Incorrectly

Wireless charging is an easy way to power up your phone. But it’s important to use the right type of wireless charger and follow the manufacturer’s instructions. Misusing wireless chargers or placing your phone incorrectly on the charging pad can generate excessive heat and damage your battery over time.

10. Constantly Charging Your Phone to 100% is another bad charging habit

While it might feel satisfying to see your phone at 100% battery life, constantly aiming for a full charge can put unnecessary stress on the battery. As mentioned earlier, lithium ion batteries perform better when maintained within a 20% to 80% range. Instead of aiming for a full charge every time, try to keep your battery level within this range for optimal battery health.


Overall, adopting good charging habits is crucial for preserving your phone battery’s health and performance. By avoiding these 10 bad charging habits, you can help ensure your phone battery remains in peak condition. Providing you with reliable power for an extended period.
