The best phones for battery life
February 25, 2025

We’ve all been there. The dreaded low battery notification pops up on your phone just as you want to take a video of the perfect moment, listen to music on your way home from work, or book that Uber.
So how do you ensure you always have battery life when you need it?
You could make sure you take your charger with you everywhere, but that’s not going to be practical. Phone battery life is largely dependent on the individual user and usage, but some phones have better batteries than others. Choosing one of these would minimise the chance of your mobile running low or conking out when you need it most.
How can you tell if a phone has a good battery?
The key features to look for in a phone with excellent battery life include:
- Battery capacity
Measured in milliampere-hours (mAh), a larger capacity generally means longer battery life. Most top phones these days will have an mAh of at least 4,500. - Charging speed
Fast charging capabilities, such as 25W or higher, can quickly replenish your battery to its full capacity. - Power efficiency
Optimised processors and software ensure minimal power wastage. - Adaptive features
Features like adaptive refresh rates and dark mode help conserve energy.

Tips for conserving battery life
In addition to selecting from the best battery life phones, you can also employ a range of daily techniques to ensure you conserve battery life for when you need it most. These include:
Adjust your screen settings
- Lower screen brightness
Reduce your screen brightness manually or enable adaptive brightness to adjust automatically to your environment. - Shorten screen timeout
Set your screen timeout and lock duration to the shortest comfortable duration (such as 30 seconds when on normal battery mode). - Close unused apps
Close apps running in the background that you don’t need open. - Restrict background data
Use settings to limit apps from refreshing data in the background, especially for non-essential apps. - Disable push notifications
Turn off notifications for apps that aren't critical.
Turn off unnecessary features
- Disable Wi-Fi, Bluetooth, and GPS
Turn off these features when they are not in use. - Use airplane mode
If you're in an area with poor reception, enabling airplane mode prevents your phone from constantly searching for a signal. - Turn off vibration
Vibration uses more power than ringtones or silent mode
