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 of the ROG Phone 5 Ultimate. This phone has a lot to offer, 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 5a offers the best of Google at a more accessible price point. You get a very clean Android experience, fast updates, and the latest version of Android. In addition, the Pixel 5a is now water-resistant, and best of all, it has the largest battery ever in a Pixel phone at 4,680mAh.

The OnePlus 9 is a fantastic all-around smartphone. It's super-fast, has a great display, and has reliable Hasselblad-tuned 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 65T system gets you from 0-100% in about half an hour.

Like the Pixel 5a, the TCL 20 Pro delivers a flagship-quality experience at a mid-range price point. With a gorgeous design, breathtaking display, and solid performance, you'll feel confident putting this phone up against devices hundreds of dollars more expensive. Plus, its 4,500mAh battery and Qualcomm 3.0 fast charging will keep you going for hours upon hours.

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 Just Black and Barely Blue. 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 (2021) 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 11 Ultra 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 67W wired and wireless fast charging when it does finally die.
