Why is battery life important?
No matter if you’re at home or travelling, it can be a nightmare when your phone battery starts to drain.
Even though portable chargers are very helpful while on the go, it’s more useful having a handset that’ll last all day - maybe even longer!
How does battery life get measured?
Before we look at mobile phones with the best battery life, let’s get to grips with the way battery life is calculated in consumer electronics.
The longevity of a battery is measured by mAh (milliampere hour). The higher the mAh, the more power that battery can hold, so it lasts longer without needing to be recharged.
What can affect your phone’s battery life?
All sorts of things can affect the longevity of your phone battery, from age and temperature to other factors such as:
- Having 4G or 5G data turned on
- Streaming videos for long periods
- Leaving apps running in the background
- Not charging your phone correctly
- The brightness level of your screen
There are things you can do to help your phone battery last longer; however, keep in mind that, like all electronic devices, no matter how well you preserve your battery, its health will still decline over time.
