Smartphones With the Best Battery Life

These 10 devices will run all day, then keep going

To some smartphone users, battery life is the single most important factor in choosing a device. After all, the best smartphone in the world isn’t worth much if it can't get you through the day without a pitstop at a power outlet.

The good news is that smartphone battery life has improved significantly in recent years, courtesy of the increased capacity of batteries—4000mAh (milliamp hours) and higher—and processors and wireless connections that smartly adjust power consumption to suit the job at hand.

Remember, a large-capacity battery requires a large-capacity shell, so the smartphones featured here tend to be on the bigger side.

To identify the models in our ratings with the best battery life, our testers use a robotic finger that simulates what a person might do with a phone in the course of an average day. The robot browses the internet, takes pictures, uses the GPS navigation, and—of course—makes phone calls. The listings are available to CR members.

Our latest battery life ratings also take into account a phone’s features. Models with wireless charging compatibility or quick-charge options are rated higher.   

Of course, great battery life doesn’t automatically equal a great overall phone, so be sure to check our smartphone ratings and buying guide to find the model that best suits your needs.

All the smartphones featured here are recommended by Consumer Reports, but they don’t all come from big-name brands or include the high-end features that a lot of consumers now take for granted. For many people, the trade-off will be worth it.

And no matter which phone you have, there are ways to extend the battery life. Here are tips from our test team.

Tips to Extend Battery Life

If your phone has a "low-power mode," you may not need to perform each of these steps. The feature automatically makes some of the adjustments when the battery drops below a certain level. 
  • Set the screen brightness to Auto so that the device can adjust to indoor and outdoor conditions.
  • Lower the baseline brightness. In most phones, you can do this by using a sliding switch in the Display menu.
  • Set the screen to go to sleep after 15 or 30 seconds of inactivity.
  • Turn on airplane mode when you’re in a location with no WiFi or cellular-data signal.
  • Reduce the frequency of updates for email, social network feeds, and other apps to once every hour.
  • If you’re streaming content over a WiFi network to stretch your data allowance (and doing other data-intensive tasks, such as internet gaming), keep a power adapter handy. Our tests have found that performing tasks over WiFi can drain batteries significantly faster than using cellular-data connections.
  • And if you need to quickly top off your battery before hitting the road, use a traditional charger instead of a wireless one. Though wireless chargers have come a long way, you generally get more juice faster by just plugging in your phone.
