How to Extend Battery Life on Your Phone and Laptop

by | Feb 23, 2026

A healthy battery makes everyday life easier.

Whether it’s your phone or laptop, battery problems usually start slowly: it doesn’t last as long as it used to, it gets hot while charging, or it drops from 30% to 10% much faster than before. The good news is that in many cases, battery life can be improved — and battery ageing can be slowed down — with a few simple habits.

In this guide, I’ll show you practical, easy ways to extend battery life on both your phone and laptop, without technical jargon. Just clear advice you can start using today.

Why Batteries Wear Out Over Time

All batteries wear down naturally. This is normal.

Phone and laptop batteries are designed to last for years, but their capacity slowly reduces with use. That means over time, they hold less charge than when they were new.

Battery wear happens faster when a device is regularly:

  • Overheating
  • Fully drained to 0%
  • Left on charge all the time in hot conditions
  • Using poor-quality chargers
  • Running too many power-hungry apps in the background

The aim is not to make the battery last forever — it’s to slow down the wear and keep it performing well for longer.

1) How to Extend Battery Life on Your Phone

Avoid Heat Whenever You Can

Heat is one of the biggest reasons phone batteries lose health faster.

If your phone often gets very warm (especially while charging, gaming, using maps, or sitting in direct sunlight), the battery ages more quickly.

Good habits:

  • Keep your phone out of direct sunlight
  • Remove a thick case while charging if the phone gets hot
  • Avoid charging under a pillow or on soft surfaces
  • Don’t leave it in a hot car

Keeping your phone cooler can make a noticeable difference over time.

Don’t Let It Regularly Drop to 0%

Many people use their phone until it shuts off. Once in a while is fine, but doing this often puts extra stress on the battery.

A better routine:

  • Charge before it gets very low
  • Try not to make 0% a daily habit
  • Small top-ups are usually better than full drains

You don’t need to obsess over the exact percentage — just avoid deep drains every day.

Be Smart About Charging

Charging habits matter more than people think.

Helpful charging tips:

  • Use a good-quality charger and cable
  • Avoid cheap chargers that heat up too much
  • Charge in a cool place
  • If possible, unplug once it’s charged rather than leaving it hot on charge for hours

Many newer phones already help manage charging in the background, which is great — but cooler, gentler charging is still better for long-term battery health.

Reduce Screen and Background Drain

The screen is usually the biggest battery user on a phone.

Easy ways to make your battery last longer each day:

  • Lower screen brightness a little
  • Use auto-brightness
  • Reduce screen timeout (so the screen turns off sooner)
  • Turn off Bluetooth/GPS when not needed
  • Close or limit apps running constantly in the background

You don’t have to turn everything off — just trimming the unnecessary drain helps a lot.

Keep Your Phone Updated

Phone updates often include battery and performance improvements, not just new features.

Keep updated:

  • Your phone’s system software
  • Apps you use regularly

Old apps can sometimes run poorly and drain battery faster than they should.

2) How to Extend Battery Life on Your Laptop

Keep It Cool and Well-Ventilated

Laptop batteries also dislike heat — and laptops create a lot of it.

If your fan is constantly loud, the laptop gets very hot underneath, or it feels hot while charging, that heat can affect battery health over time.

What helps:

  • Use the laptop on a hard, flat surface (not a bed or sofa)
  • Keep vents clear
  • Clean dust from vents and fans regularly
  • If it runs hot all the time, consider a professional internal clean

A cooler laptop battery usually lasts longer and performs more consistently.

Don’t Keep It at 100% All the Time (If You Mostly Use It at a Desk)

If your laptop is plugged in all day, every day, the battery can wear out faster — especially if the machine also runs warm.

Many modern laptops have a battery care mode that limits charging (for example, stopping around 80%). If your laptop has this feature, it’s worth turning on if you mostly use it at a desk.

Simple rule: if your laptop lives on a charger most of the time, using battery care settings can help preserve long-term battery health.

Avoid Full Drains

Just like phones, laptop batteries don’t enjoy being regularly drained to 0%.

Better habit:

  • Charge before it gets critically low
  • Avoid letting it fully die all the time
  • Use normal charging cycles rather than extreme full drain/full charge patterns

Steady habits are better than “battery training” myths.

Use Battery Saver / Power Mode

Most laptops have built-in power settings that can give you more battery life during the day.

Helpful settings:

  • Battery Saver / Power Saver mode
  • Lower screen brightness
  • Turn off keyboard backlight when not needed
  • Reduce sleep/display timeouts
  • Close heavy apps you’re not using

If you only need web browsing, emails, or documents, these settings can make a big difference.

Be Careful With Cheap Chargers

A poor-quality replacement charger can cause unstable charging, excess heat, and long-term damage risk.

Safer approach:

  • Use the original charger where possible
  • If replacing it, buy a trusted, correct-spec charger
  • Avoid “too cheap to be true” options

A proper charger protects both your battery and the laptop itself.

3) Battery Habits That Help Both Phones and Laptops

Use the Right Charger and Cable

Bad cables and low-quality chargers can cause heat, slow charging, or unstable charging.

  • Use reliable chargers
  • Replace damaged cables (especially frayed ones)
  • Avoid charging accessories that get unusually hot

Watch for Background Apps

If your battery suddenly starts draining much faster, an app may be running in the background all the time.

Check for:

  • Apps using a lot of battery in settings
  • Apps constantly refreshing, syncing, or using location
  • Programs you forgot were open

A quick check can often solve “mystery” battery drain.

Restart Devices Regularly

A simple restart can clear stuck processes and reduce unnecessary battery use.

Good habit:

  • Restart your phone every few days
  • Restart your laptop regularly (not just sleep mode)

It’s a small habit that helps performance and battery life.

4) Common Battery Mistakes to Avoid

These are very common and easy to fix:

  • Leaving a device in a hot car
  • Using very cheap chargers and cables
  • Letting the battery hit 0% too often
  • Ignoring overheating
  • Keeping maximum brightness all the time
  • Running lots of apps in the background
  • Never updating the device

You don’t need perfect habits. Even improving a few of these will help.

5) Signs Your Battery May Be Wearing Out

If you notice these signs often, your battery may be ageing or the device may need a check:

  • Battery drops quickly even with light use
  • Device gets hot during normal use
  • Phone or laptop shuts down at random percentages
  • Charging is unusually slow
  • Battery percentage jumps up or down suddenly
  • Laptop only works well while plugged in

Sometimes it’s just a setting or an app causing the issue. Other times, the battery itself may be reaching the point where replacement is the best option.

6) A Simple Weekly Battery Care Routine

If you want a practical routine, this is enough for most people:

  • Check for system/app updates
  • Restart your phone and laptop
  • Close apps/programs you don’t use
  • Lower brightness if it’s always at maximum
  • Check for overheating while charging
  • Inspect charging cables for damage

It only takes a few minutes and helps your devices stay healthier for longer.

Final Thoughts

Battery life gets better when your habits get a little better.

You don’t need to monitor percentages all day or change the way you use your devices completely. Just avoid heat, charge a bit more gently, use good chargers, and keep an eye on background drain.

These small changes can help your phone and laptop stay reliable for much longer — and save you the frustration of poor battery life when you need your devices most.

And if your battery is already draining fast, getting hot, or behaving strangely, it’s often worth checking it early. A quick battery health check can sometimes solve the issue before it turns into a bigger repair.
