Phones with best battery life in 2024

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. Thought portable chargers and battery packs can be useful, carrying round them around can be cumbersome, and it’s just one more thing to keep charged.

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.

What other factors affect the battery life?

There are lots of different things that can affect how long your battery lasts - besides the size of your battery  - such as:   

  • Your phone processor – newer processors work faster, using less energy and less heat meaning battery life lasts longer 

  • The operating system – newer systems are optimised to use less battery and get work done more quickly 

  • How old the battery is – the more charging cycles, the shorter its life  

  • The brightness level of your screen – the brighter your screen the more power it needs 

  • Using your network – making calls, using your data, and using GPS or location services can all drain your battery. Try using WiFi when you can as this uses less power.  

  • Gaming – especially 3D games require a lot of processing and power from your phone. Check out our list of the best gaming phones

  • Watching videos – especially in ‘picture in picture’ mode   

  • Multi-tasking – having apps running in the background will drain your battery, especially if they ping you with frequent notifications  

The importance of fast charge 

The life and size of your battery is important, but when you need to charge your phone then time is of the essence. Fast-charging has become a must-have feature in a lot of smartphones, but how does it work?   

A basic USB port sends just 2.5 watts (W) to your phone battery, but fast-charging increases this wattage amount so your phone charges more quickly. There are a few different methods to achieve this:  

  • USB Power Delivery: also known as USB-PD, is technology that enables a USB port to deliver up to 100W to your battery.  

  • Qualcomm Quick Charge: Qualcomm is a type of processor used for flagship Android devices. The latest processors are compatible with Quick Charge 4+, which has a maximum power output of 100W. 

  • Samsung Adaptive Fast Charging: This is used by flagship Samsung devices. It has a maximum power output of 18W and will automatically change charging speeds to maintain the battery's longevity. 

Wireless fast-charging is also on the horizon – though this progress is a little slower as a lot of heat is generated in fast-charging, and managing this heat wirelessly can be tricky.

There are lots of different factors that affect battery life, but battery size is an important one - currently the most powerful phone batteries on the market are around 5,000 mAh. Read on to find out our top picks for phones with the best battery life from each major brand.
