7 Common Habits That Ruin Your Phone Battery (And Solutions)

Our smartphones are an essential part of daily life, yet nothing is more frustrating than a phone battery that won’t last through the day. The good news is that most battery issues stem from habits that are easy to correct. From overcharging to using the wrong settings, these common habits can slowly degrade your phone’s battery life. In this post, we’ll analyze the top 7 mistakes that ruin your phone battery and how to prevent them. Keep reading to learn how to stop these 7 habits that kill your phone battery and extend the life of your device.

1. Overcharging Your Phone: Why It’s Bad and How to Avoid It

Many of us leave our phones plugged in overnight or continuously charge them, thinking it ensures we’ll wake up to a fully charged device. However, overcharging can cause your battery to degrade faster over time. Once your phone reaches 100%, it stops charging but continues to receive small trickle charges, which stresses the battery.

The solution is simple: avoid leaving your phone plugged in for extended periods after it’s fully charged. Instead, unplug your phone once it reaches 100% or use a smart plug that can automatically turn off the charger. Alternatively, you can charge your phone during the day when you can monitor its charge level.

2. Letting Your Battery Drain Too Low

While overcharging is bad, so is letting your battery drain to 0% frequently. Deep discharges can shorten the battery's overall lifespan because lithium-ion batteries are designed to operate within a charge range of 20-80%. Constantly letting your phone die puts unnecessary strain on the battery cells, causing them to wear out faster.

To prevent this, aim to recharge your phone when the battery hits around 20% and unplug it at 80% if possible. Some newer phones even offer a feature to optimize battery charging, which limits how much your phone charges to extend its lifespan.

3. Using Your Phone While It’s Charging

A common mistake is using your phone while it’s plugged in, whether it’s playing a game, streaming videos, or scrolling through social media. This habit generates excess heat, which is one of the leading causes of battery damage. When your phone is working hard while charging, it heats up, and this heat can degrade the battery more quickly.

To fix this, minimize heavy use of your phone when it’s charging. If you must use it, stick to light tasks like answering messages or browsing the web. If possible, let your phone rest during charging to allow it to cool down properly.

4. Keeping Your Screen Brightness at Maximum

One of the most battery-draining features of any phone is the screen. Keeping your brightness at maximum all day can have a significant impact on how fast your battery drains. Your screen doesn’t need to be at full brightness all the time, especially indoors or at night.

To conserve power, enable the auto-brightness feature that adjusts the screen based on ambient light conditions. This not only reduces battery usage but also protects your eyes from strain. Another great habit is reducing screen timeout so your phone’s display turns off quicker when not in use.

5. Allowing Background Apps to Run

Background apps are often silent battery killers. When you leave multiple apps running in the background, they continue to use your phone’s processing power and data, even if you're not actively using them. Over time, this constant background activity drains your battery unnecessarily.

To solve this issue, regularly close apps that you’re not using, or better yet, check your phone’s settings to see which apps are using battery in the background. Both Android and iOS devices have settings to limit background activity, which can significantly extend battery life. You can also use battery-saving modes to cut down on unnecessary background processes.

6. Exposing Your Phone to Extreme Temperatures

Extreme temperatures—whether hot or cold—can severely impact the performance of your phone’s battery. Heat can cause the battery to overheat and swell, while cold can slow down the battery’s ability to function properly. Leaving your phone in direct sunlight or using it in freezing conditions can result in permanent damage.

The best solution is to always keep your phone at room temperature. Avoid leaving it in hot environments like a car dashboard or using it for long periods under the sun. Similarly, try to protect your phone in cold weather by keeping it in your pocket or inside your coat when you’re outdoors.

7. Ignoring Software Updates

Another common habit that can negatively affect your phone battery is neglecting software updates. Manufacturers frequently release updates to improve battery performance, fix bugs, and optimize how apps and features use power. Skipping these updates means you’re missing out on potential battery life improvements.

Make it a habit to check for updates regularly. This will ensure your phone’s battery management is as efficient as possible. Additionally, avoid using outdated apps, as these may be less optimized and drain more battery.

8. Keeping Too Many Notifications Active

While it’s convenient to get notified about every new email or app update, constantly receiving notifications lights up your screen, vibrates your phone, and potentially plays a sound—all of which consume battery. If you’re constantly getting notifications from multiple apps, this can significantly contribute to battery drain.

To fix this, disable non-essential notifications. Prioritize only important apps and turn off notifications for things like social media, promotions, and unnecessary alerts. Both Android and iOS devices have settings where you can manage app notifications to ensure only the essentials consume your battery.

9. Using Non-Certified Chargers and Cables

Using non-certified or low-quality chargers can damage your phone’s battery in the long run. These chargers may not meet your phone’s specific requirements, causing inefficient charging and even potential damage to the internal battery. Cheap or fake chargers also often lack proper insulation and over-voltage protection, putting your phone at risk.

To avoid this, always use the charger and cable that came with your phone or buy certified replacements from reputable brands. Investing in a high-quality charger ensures that your phone is being charged safely and efficiently, which can prevent long-term battery damage.
