Best battery life phones

There are lots of things to consider when you're buying a new phone, and battery life is one of the most important – you don’t want to run out of juice in the middle of an important phone call, or when you’re following directions to somewhere new.

To help you choose the best smartphone, we've put together a list of the best performers when it comes to battery life.

mAh battery

The unit of battery capacity is mAh (milliampere/hour). The bigger the mAh value, the more powerful the battery is. This measurement gives an indication of how long your phone can operate between each full charge. However, this is only an estimate because how you use your phone will impact how long the battery lasts. For example, activities such as gaming will use more battery capacity than sending a text.

Which phone has the biggest battery life?

At present, the biggest battery on the phone market is 5,000mAh, and some of the phones with this powerful battery include: Samsung Galaxy S23 Ultra, Samsung Galaxy S22 Ultra, Google Pixel 7 Pro, Google Pixel 6 Pro and Xiaomi 11T Pro.

Charging your battery when you're out and about

If you forget to charge your phone and you can see you're running low on power, a power bank is the ideal solution for on-the-go battery top-ups. Just fully charge them at home, and make sure you've got the right cable which connects your power bank to your phone.

They're especially good for festivals, camping trips, and days where you might be away from a power socket for a long time.

Which apps drain your phone battery the most?

Apps which use battery-intensive functions, such as cellular activity, camera or location, typically drain your battery the most. The apps that drain your phone battery the most will be different for everyone, and you can often check which apps are eating up your battery by selecting Settings and then Battery.

The good news is that most apps have a dark mode which reduces your screen’s brightness and your battery consumption, meaning you can use your favourite apps for longer. Additionally, the majority of phones will have a power saving mode which stops apps running in the background when you’re not using your phone – see the ‘How to save your phone battery and make it last longer’ section for more detail.

How to save your phone battery and make it last longer

If your battery is running low, here are some tips on how to make it last longer:

  • Turn down your screen brightness. The brighter your screen, the higher the demand on your phone’s battery. This is our number one tip as a bright screen is often the biggest drain on phone batteries.

  • Avoid or limit battery-intensive activities like listening to music, browsing or gaming (especially games with intensive graphics).

  • Turn off WiFi if you don’t need it. When your WiFi connection is turned on, your phone is always looking for a hotspot.

  • Disable app push notifications. This means your phone won’t light up or make a noise for new notifications.

  • Turn on your device’s power saving mode. For Apple devices, this is called Low Power Mode, Pixel devices have Power Saver, and Samsung and Xiaomi devices have a Power Saving Mode. Or if your battery is really low, turn on Airplane Mode.

  • If you have one of our Vodafone EVO plans, use our Battery Refresh service to keep your phone running at its best with free battery health checks and replacements. It’s included as part of your plan for up to three years, if you buy a brand new phone with us.
