Google patents a new way to conserve your phone’s battery life

Cell phone manufacturers are always looking for new ways to help reduce the rapid loss of battery life, something that is becoming increasingly difficult as advances are made that let us use our phones for more and more, taking an even bigger toll on the battery. (Remember the days when your phone could go for days in between charging?)

The most common two suggestions for conserving battery life are quitting out of all apps that run in the background, even after closing them out, and turning down the brightness on your screen. Many phones will sense the life left in your battery and automatically reduce the brightness on its own — or even do it based on whether your current activity warrants a vibrant screen.

google-oled-patent-569x650Unconvinced that brightness is the function that should be focused on, Google’s new mobile patent would see that devices focus on three other display variables.

First, once the device senses that the battery life is entering the dangerously low zone, the phone will disable and blur and animation functions which would otherwise be automatic.

As the battery continues to drain, the phone will make its next move. In addition to the above, it will then reduce the phone’s resolution.

Finally, the patent shows that a third step will be taken, and the phone will only allow select colors to appear on the display.

On the one hand, if the above helps to make our phone’s battery last even longer, it’s a good thing. But on the other hand, we pay extra for devices with beautiful screens, and brightness reduction seems like an aesthetically better way to save on battery life.

Which phone has the best battery life? Let’s find out
Moto G Stylus

Smartphones exist to make our lives easier, offering a wide variety of functions that help to simplify daily life while helping us stay connected to each other. These daily connections and simplifications have become essential to our everyday lives. Because of this, we bank on these devices to be dependable above all else, and a huge part of that dependability is battery life. Being well aware that battery life is a major selling point for any device, smartphone manufacturers now tout how long a battery could feasibly last given its technical specifications. Despite this type of specificity, how do we know for sure that a phone’s battery will last for as long as the manufacturer claims?

We've handpicked some of the phones with the best battery life that are currently available, from the Huawei P40 Pro through to budget-friendly phones like the Moto G7 Power. Opt for one of these phones to help avoid suffering the pain of running out of juice midway through an important Zoom call or epic Netflix binge -- or not making it to the end of the working day without having to plug in your phone.

Addicted to your phone? Try one of Google’s clever new ‘experiments’

You know you need to spend less time on your phone, and Google agrees. To that end, the company announced a set of new apps and tools to help you spend a little less time on your device -- and more time being a little more productive. The new apps are part of a set of new Digital Wellbeing "experiments," which are now available in the Google Play Store.

Digital Wellbeing, in general, was originally launched as a way for users to track how much they use their phone and the apps on their phone, and as a way to limit that usage. The five new apps are part of that initiative, however, they don't seem to require Digital Wellbeing to actually be on your phone -- so you can still take advantage of them if you don't have a recent version of Android with Digital Wellbeing.
