The best smartphone in the world isn’t worth much if you need to recharge it every few hours. That's why we decided to take a closer look at our smartphone ratings to find the phones with the best battery life. (Also check out our review of the best smartphone cameras.)

The five smartphones below manage to stand out, even in a field that has seen significant improvement in recent years, thanks to batteries with 3,000mAh and higher of storage, plus processors and wireless connections that smartly adjust power consumption to suit the job at hand. 

All of these models offer rapid charging, which can bring a near-dead handset back to life (30 to 60 percent capacity) within roughly 30 minutes, assuming you use the high-output charger that came with your phone. Some also work with wireless charging pads. But none have removable batteries.

Best of all, each of the five smartphone models—ranked in order of battery performance—is among the top overall performers in our smartphone ratings. In fact, the phone topping this list, the Samsung Galaxy S8+, is also our top phone overall.

To test battery life, our engineers precisely measure smartphone battery drain under a variety of conditions, including pulling down data from both cellular and WiFi networks.

Some of these models are equipped for wireless charging. If they support both Qi and PMA standards, they'll work with pretty much any wireless charger—even one you've had on hand for years.

Remember, a large-capacity battery requires a large-capacity shell, so, yes, these phones tend to be on the bigger side.

Tips to Extend Battery Life

Here are five ways to squeeze more juice from any phone.

  • Set the screen brightness to Auto so 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 an area with no signal.
  • Reduce the frequency of updates for email, social-network feeds, and other apps to once every hour.
  • If you're streaming content (and performing other data-intensive tasks such as internet gaming) over a WiFi network to stretch your data allowance, keep a power adapter handy. Our tests found that performing tasks over WiFi connections can drain batteries sigificantly faster than using cellular-data connections.
