If battery life is the most important factor that goes into your decision of what phone to buy, you may want to consider one of these phones. However, even though these phones perform very well when it comes to battery life, their other features may not be as good.

The ZenFone 3 Zoom (released in February 2017) may have the longest-lasting battery, but it doesn’t work with Verizon or Sprint, and it doesn’t perform as well as other phones in different areas. Like with any phone, do your research before you buy something new. There are lots of factors that go into how long a phone’s battery lasts.

What Affects Battery Life?

Did you notice that a lot of these phones are larger ones, like the iPhone 8 Plus? The actual size of the phone’s battery is definitely a factor. The bigger phone means there’s room for a larger battery, which also means a longer battery life. But a larger phone may also drain your battery faster. The larger screen size of some of these phones needs more juice to work than a phone with a smaller screen.

There are also several settings on your phone that could be draining your battery faster:

• You gave too many apps permission to send you push notifications

• You leave Bluetooth on when you don’t need it

• Apps use location finder at all times in the background

• You don’t close out of apps when you’re done using them

• Your screen’s brightness is always turned up high

• You have your phone on vibrate

Adjusting some of these settings could help your phone last longer. Check out our tips on making smartphone batteries better to learn more about the future of this technology.
