Android Phones with the Best Battery Life 2021

Samsung took a modest step forward in 2021, except when it comes to the Galaxy S21 Ultra. Samsung pulled out all the stops on its S21 superphone with a 10x optical Zoom, QHD+ 120 Hz screen, and 4,500 mAh battery. Of course, if you want this phone to be a battery champ, you can ratchet down the refresh rate to 60Hz and FHD+ resolution. But overall, it's hard to go wrong with the best of the best Samsung has to offer.

ASUS is pulling out all the stops with its latest Republic of Gamers phone, the ROG phone 5. This isn't the most tricked-out version, that belongs to the ROG Phone 5 Ultimate. This phone has a lot to offer though, including a 6,000 mAh battery, Snapdragon 888, 8GB of RAM, and more. Gaming phones are known for their big batteries and this one is no exception.

The Samsung Galaxy S20 FE was one of Samsung's best offerings of 2020. It cuts all the right corners to give you great performance, camera, and battery. The phone is a battery champion that will last multiple days if you let it. The fact that it's one small step short of a full-blown flagship is a bonus.

The Google Pixel 5 is the best that Google has to offer. You get a very clean Android experience, fast updates, and the latest version of Android. You can even install beta builds if you want to. Google offers many benefits to using its phones, and the best part is, you also get great battery life.

The OnePlus 8T is a fantastic all-around smartphone. It's super-fast, has a great display, and reliable cameras. Its 4,500 mAh battery allows for top-notch endurance throughout your days of use, and when it comes time to charge up, the Warp Charge 65 system gets you from 0-100% in just 39 minutes.

LG has been quiet of late, but its 2020 flagship, the LG V60 ThinQ 5G is well known for exceptional battery life. It should be with a 5,000 mAh power cell in there. Part of that has to do with the Dual screen case you can pick up for the LG V60 which gives it a second screen for dual-screen apps and multitasking.

If you want the best Google experience, but you're on a tighter budget (and you don't care about 5G), the Pixel 4a is a great pick. It's not the most powerful, but it runs silky smooth. It's available with 6GB of RAM and 128GB of storage and comes in any color you want as long as it's black. The fingerprint sensor on the back of the phone is a little old-school, but the screen size is perfect for one-handed use, and the phone just lasts and lasts.

You don't have to spend a ton to get great battery life, and the Moto G Power shows us why. Simple software and limited hardware features pair well with a 5,000 mAh battery, and the result is a phone that can last up to three days on a single charge. Yes, you read that right — three days.

Our last pick is for those reading this that don't live in the U.S. The Xiaomi Mi 10T Pro is a rock-solid handset in more ways than one, with battery life being one of its strongest aspects. You get a huge 5,000 mAh battery that allows for well over a day of use, along with 33W fast charging when it does finally die.
