A phone’s battery life is affected by various factors besides capacity, so it’s hard to go by the specs. While you can extend your phone’s battery life, there’s only so much you can do manually. Rest assured that the phones listed below are sure to provide excellent battery life.
1 iPhone 16 Pro Max
Battery capacity: 4685 mAh
Wired charging speed: Up to 50% in 30 minutes with a 20W adapter
If you’re already part of the Apple ecosystem, the iPhone 16 Pro Max is a no-brainer for you. It’s Apple’s latest and most powerful iPhone yet, so if you’re looking for a premium device that not only lasts a long time, but also handles demanding tasks with ease, this should be your choice.
The actual capacity of the cell in it may not seem impressive, since 5000 mAh is now standard on Android phones. But rest assured that the A18 Pro chip in the iPhone 16 Pro Max is efficient enough to minimize battery consumption and provide more power for longer.
2 Asus ROG 8/8 Pro phone
Battery capacity: 5500 mAh
Wired charging speed: 100% in 39 minutes with a 65W adapter
Asus ROG phones have always focused on gamers, but the ROG Phone 8 looks and feels more like a regular device. This means a slimmer design, a thinner and lighter body, thinner bezels, OIS, a special telephoto lens, a punch-hole selfie camera, wireless charging and IP68 protection.
All this while maintaining a massive 5500mAh cell, a highly efficient Snapdragon 8 Gen 3 chip, a headphone jack, excellent thermal protection, a remappable shoulder trigger, two USB-C ports for charging while playing in landscape mode, and a hidden LED screen. a back that is actually functional.
3 RedMagic 9S Pro
Battery capacity: 6500 mAh
Wired charging speed: 100% in 35 minutes with 80W adapter
The Red Magic 9S Pro is a step up from the Asus ROG Phone with a whopping 6500mAh battery, the biggest on this list. But don’t click the buy button just yet. As impressive as the battery life is, note that the device is made for the niche market.
For one thing, it has an under-display front-facing camera that—as futuristic as the phone looks—produces noticeably worse selfie photos and videos.
Second, the device does not have an official IP68 rating, as the built-in cooling fan does not allow for any water or dust resistance. Finally, there’s no telephoto lens on the back, so if you shoot a lot of portraits, you’ll be disappointed.
Basically, you should only buy the Red Magic 9S Pro if you plan to play more serious games, want an uninterrupted display, and don’t mind the sacrifices it makes.
4 Samsung Galaxy S24 Ultra
Battery capacity: 5000 mAh
Wired charging speed: up to 65% in 30 minutes with a 45W adapter
The Galaxy S24 Ultra uses a custom version of the Snapdragon 8 Gen 3 chip, which is slightly more powerful and efficient, allowing it to gain an edge over other Android phones with the same battery capacity. While demanding tasks are more demanding, basic tasks like browsing the web, streaming video, and scrolling through social media consume almost no battery life.
You can also significantly extend battery life on the S24 Ultra by tweaking the power saving mode to limit apps and the home screen and only allow essential apps. This feature can be a lifesaver if you’re out of battery and don’t have access to an electrical outlet or adapter, but still need to stay within range.
Apart from that, you also get the flagship camera system, S Pen stylus and titanium body.
5 Nothing Phone (2a) Plus
Battery capacity: 5000 mAh
Wired charging speed: up to 50% in 21 minutes with a 50W adapter
If you’re looking for something that’s affordable, meets all the basics, and has a unique personality unlike other offerings in its price range, the Nothing Phone (2a) Plus is the phone to go for. It’s basically a lightweight version of the Nothing phone (2 we reviewed) in 2023.
The main feature of the device is the Glyph Interface, where the LEDs on the back of the device can be programmed to light up when needed and act as indicators for important notifications, messages from certain contacts, and more.
The Glyph Interface is designed as a lifestyle feature that tries to reduce screen time, but even if you don’t find it that useful and don’t intend to use it, the device still offers more than enough value for the price.
6 Samsung Galaxy A16
Battery capacity: 5000 mAh
Wired charging speed: 25W
The Galaxy A16 is Samsung’s entry-level offering for 2024, and at the price it’s available, it’s a steal. That’s not just because of its 5000mAh battery, but also because it’s the company’s first budget phone to come with six years of major Android updates. This means the A16 will receive updates until October 2030. No other Android phone at this price is supported for that long.
Samsung also added an IP54 rating and a more powerful processor, while expanding the display size to 6.7 inches. Since you probably won’t be doing heavy duty on this device, the 5000mAh is more than enough to last you a day or more, making it an ideal choice if you’re on a budget and you care about longevity.
7 OnePlus 12R
Battery capacity: 5500 mAh
Wired charging speed: 100% in 26 minutes with a 100W adapter
Not many mid-range phones can claim to compete with today’s flagships, but somehow the OnePlus 12R still manages to pull it off. A hefty 5500mAh battery paired with an efficient Snapdragon 8 Gen 2 chip allows it to offer better battery life than some $1000 phones.
The device also has IP64 protection and Gorilla Glass Victus 2 protection on the front. And if you’re still not convinced, it also supports 100W charging and comes with an 80W adapter in the box for US customers.
All in all, these are the best smartphones you can buy in 2024 if battery life is your top priority. You can’t go wrong with any of them, but your options may be limited depending on your budget.
