What good is your phone if the battery dies? If you use your phone hard and don't have the option to charge throughout the day, battery life is your number one priority when shopping for your next phone. Thankfully several great options focus on battery life and won't give up halfway through the day.
- Our pick: Samsung Galaxy S20 Ultra
- More balanced: Samsung Galaxy S20+
- Great with a stylus: Samsung Galaxy Note 10+
- Affordable flagship: OnePlus 7T
- Best for much less: Moto G8+
- Go two days: ASUS ROG Phone 2
Our pick: Samsung Galaxy S20 Ultra
Staff pickWith a 5,000mAh battery and the latest processor inside, the S20 Ultra can provide exceptional battery life. It can stand up to the absolute heaviest days if you choose to keep the screen set at 60Hz refresh rate as well. It's also a massive and feature-packed flagship in every other respect.
More balanced: Samsung Galaxy S20+
For $200 less than the S20 Ultra, you can get an S20+ that has a 4,500mAh battery. It may be smaller but you get nearly the same battery life. You're getting a slightly smaller screen, and less-capable rear camera zoom, but it's also easier to hold and use in one hand.
Great with a stylus: Samsung Galaxy Note 10+
The Note 10+ is technically no longer Samsung's latest and greatest, but its 4300mAh battery leads to great longevity. Samsung's great battery management and efficient specs give the Note 10+ all-day battery even when you hit it hard. And you'll want to because a Note is a wonderful productivity tool.
Affordable flagship: OnePlus 7T
OnePlus just keeps doing it: a flagship-level phone with amazing hardware, specs, and capabilities for hundreds of dollars less than the competition. You'll still get a big screen, top-notch internals, and truly excellent battery life thanks to simple and efficient software.
Best for much less: Moto G8+
You don't have to spend a ton to get great battery life, and the Moto G8+ shows us why. Simple software and limited hardware features pair with a 4,000mAh battery for good battery life, and the rest of the phone rounds out nicely for a good value offering. U.S. buyers note: this is an international version with no warranty.
Go two days: ASUS ROG Phone 2
The ROG Phone 2 has everything turned up to 11: there's RGB lighting at the back, a Snapdragon 855+ chipset, a 120Hz display that's incredibly smooth, and a 6000mAh battery that lasts two days. It's a behemoth that isn't for everyone, but ultimate battery fiends will want to take a closer look.
Have your phone last all day
The Galaxy S20 Ultra offers fantastic battery life, and also does everything else you could want out of a massive power user-focused phone. You're getting a massive screen, the highest-end specs, and tons of features in hardware and software. It's no wonder why it's one of the best Android phones overall right now.
It has friends in this space, though, namely Samsung's own Galaxy S20+, which offers nearly as good battery life for a couple of hundred dollars less. Then there's the ASUS ROG Phone 2, which goes in the other direction and gives you potential two-day battery life but loses the svelte exterior and refinement of Samsung's phones.
For a dramatically lower buy-in, the OnePlus 7T has fantastic battery life, but with that lower price comes up short in a few other areas like the camera.
