Best Battery Life Phones (Updated 2021)

1. Samsung Galaxy S10+ 4,000mAh

Samsung Galaxy S10+ phone remains a flagship handset for Samsung 2019 S series. What makes it stand out is its large 6.4-inch edge-to-edge screen that displaces the front camera to the top corner. With a screen-to-body ratio of 93.1%, the pixels stretch from a small top speaker to the bottom, spilling over to the right and left edges. It is this unique design that redefines what a phablet should look like.

Its AMOLED display features three different resolutions: the Full HD+, QHD+, and the HDR10+. The Full HD+ is the default resolution, but you can crank it up to QHD+ or the HDR10+ for additional color and contrast. This feature is particularly handy for those watching movies from their mobile devices.

Its 4,000mAh battery capacity is to be revered. You can stream Netflix videos, play games, and engage in a few hours of Spotify streaming and still have an impressive 10-30% of charge left. Moreover, you can add a few hours of operation by switching to either of the phone’s power-saving modes.

In addition to the long battery life, the phone is equipped with Samsung’s new Wireless PowerShare feature. This means the device turns into a Qi charging mat to help charge a friend’s phone when low on battery. It’s pretty easy to activate the feature as it is located in the quick settings menu under the notification bar. With Samsung’s One user interface navigating the menu is a breeze.

This may not seem like much, but given its excellent resolution and exemplary camera, it’s a lot of runtime. Besides, it is a super-fast charging phone, which means if in the event it runs out of power, you can have it up and running within a short while.
