Battery draining fast? The best tips to save the battery

If your phone battery is regularly drained quickly, there can be many reasons for this. If you have charged your mobile phone properly but you are still soon having rechargeable battery problems, it’s worth taking a closer look at your smartphone. We’ll show you a few simply ways to optimise battery usage.

Battery usage by apps

Push notifications on the home screen are handy to always stay up to date. However, they are often the reason why your phone battery is draining fast. You should thus consider whether you really want the notifications for each of your apps.

In the settings, choose which apps you want to send you notifications – and which you don’t. The best way to do this depends on the brand and the model of your smartphone. Find out more about what you can do if your iPhone is draining quickly or your Samsung is draining quickly.

Tip: If you want to find out how to optimise your battery life, we recommend you take a look at the usage indicator in the battery settings on your mobile phone. Take a close look at the apps with a high battery usage and delete all of those that don’t offer you any added value – this also makes your mobile phone much tidier!

Deactivate WLAN

If you’re outside on the move, you’ll presumably use your mobile data to stay contactable. But beware: Even if you’re not in a WLAN area, your mobile phone will search for suitable WLAN networks in the surrounding area – and WLAN uses a lot of battery.

This is particularly true for areas with weak WLAN, such as on long train or car journeys. So, deactivate your WLAN when you’re on the move to save battery.

Mobile screen shows the device settings

Set the display brightness

If you are wondering why your phone battery is draining quickly, it’s worth taking a look at your display. A bright display is handy in many situations, but it often also consumes unnecessary amounts of battery life– especially on cloudy days and indoors, an excessively bright display isn’t needed.

By the way, your mobile phone knows how to optimise the display itself: In the settings, simply select the automatic brightness option to quickly save your battery and prevent your phone battery from being drained quickly due to a bright display.

Protect phone battery from the cold

Wintery cold is no good at all for phone batteries. If your phone battery is draining fast and charges slowly, this might be due to the temperature. The good news: There are things you can do to protect your mobile phone from adverse temperatures and save the battery. Carry the mobile phone close to your body in minus temperatures and do not let it lie in the cold for prolonged periods.

By the way: Excessive heat is also bad for your smartphone. In summer, a protective sleeve can work wonders to prevent direct sunlight on your mobile phone – although a protective sleeve is recommended in general so you can enjoy your phone screen for a long time.

Switch off the vibration alert

If your mobile phone not only rings when you receive a call but also vibrates, the question is: Does this usually preset function really offer you a benefit in everyday life? If not, you should quickly go into the tone settings on your mobile phone to switch off the vibration. Admittedly, this only has a limited effect on your battery, but sometimes all the little things that eat up your battery add up.

If your mobile phone gets hot and the battery is drained fast

If your mobile phone frequently gets very hot and drains fast, this may be due to a faulty battery. In this case, you should contact the manufacturer or a professional mobile phone service right away to have your rechargeable battery checked professionally and, if necessary, replaced.
