These 7 Phones Give You the Most Battery Life

Various factors affect a phone’s battery life besides its capacity, so it’s hard to go by the spec sheet. While you can extend your phone’s battery life, there’s only so much you can do manually. Rest assured, the phones below can surely deliver excellent battery life.

1 iPhone 16 Pro Max

Battery capacity: 4,685mAh

Wired charging speed: Up to 50% in 30 minutes with a 20W adapter

If you’re already a part of the Apple ecosystem, the iPhone 16 Pro Max is a no-brainer. It’s Apple’s latest and most powerful iPhone to date, so if you’re looking for a premium device that not only lasts long but also handles demanding tasks with ease, this should be your pick.

The actual capacity of the cell in it may not seem impressive, considering 5000mAh is the standard on Android phones now. But rest assured, the A18 Pro chip in the iPhone 16 Pro Max is efficient enough to minimize battery consumption and deliver more power for longer.

2 Asus ROG Phone 8/8 Pro

Battery capacity: 5,500mAh

Wired charging speed: 100% in 39 minutes with a 65W adapter

Asus ROG Phones have always targeted gamers, but the ROG Phone 8 looks and feels more like a mainstream device. That means a subtler design, a slimmer and lighter body, thinner bezels, OIS, a dedicated telephoto lens, a hole-punch selfie camera, wireless charging, and an IP68 rating.

All that while still packing a beefy 5500mAh cell, a highly efficient Snapdragon 8 Gen 3 chip, a headphone jack, excellent thermals, remappable shoulder triggers, two USB-C ports to keep charging while gaming in landscape mode, and a hidden LED screen on the back that’s actually functional.

3 RedMagic 9S Pro

Battery capacity: 6,500mAh

Wired charging speed: 100% in 35 minutes with an 80W adapter

The Red Magic 9S Pro goes a step above the Asus ROG Phone with a whopping 6500mAh battery, the biggest one 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 a niche market.

For one, it has an under-display front camera, which—as futuristic as it makes the phone look—produces noticeably worse selfie photos and videos.

Secondly, the device doesn’t have an official IP68 rating since the built-in cooling fan doesn’t allow for any water or dust resistance. And lastly, there’s no telephoto camera on the back, so if you take a lot of portrait photos, you’ll be disappointed.

Basically, you should only buy the Red Magic 9S Pro if you’re planning to do some serious gaming, want an uninterrupted display, and don’t mind the sacrifices it comes with.

4 Samsung Galaxy S24 Ultra

Battery capacity: 5,000mAh

Wired charging speed: up to 65% in 30 minutes with a 45W adapter

The Galaxy S24 Ultra uses a bespoke 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 taxing, basic tasks like web browsing, video streaming, and social media scrolling consume hardly any battery life.

You can also dramatically increase battery life on the S24 Ultra by tweaking the power saving mode to limit apps and the Home screen, allowing only essential apps. This feature can be a lifesaver if you’re low on battery and don’t have access to a power outlet or adapter but still need to remain reachable.

Aside from that, you also get a flagship camera system, the S Pen stylus, and a titanium body.

5 Nothing Phone (2a) Plus

Battery capacity: 5,000mAh

Wired charging speed: up to 50% in 21 minutes with a 50W adapter

If you’re looking for something that’s affordable, nails all the fundamentals, and has a unique personality, unlike other offerings in the price bracket, the Nothing Phone (2a) Plus is the phone of choice. It’s essentially a lite version of the Nothing Phone (2) we reviewed) in 2023.

The highlight feature of the device is the Glyph Interface, where the LEDs on the back of the device can be programmed to light up when required and function as indicators for important notifications, messages from certain contacts, and more.

The Glyph Interface is designed to be a lifestyle feature that attempts to reduce your 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: 5,000mAh

Wired charging speed: 25W

The Galaxy A16 is Samsung’s entry-level offering for 2024, and it’s a steal for the price at which it’s available. That’s not just because of its 5000mAh battery but because it’s the first budget phone from the company to come with six years of major Android updates. That means the A16 will get updates till October 2030. No other Android phone at this price is supported for this long.

Samsung has also added an IP54 rating and a more powerful processor while expanding the display size to 6.7 inches. Given that you’re probably not going to be doing demanding tasks on this device, the 5000mAh is more than enough to last you a day or even longer, making it the perfect choice if you’re on a tight budget and care about longevity.

7 OnePlus 12R

Battery capacity: 5,500mAh

Wired charging speed: 100% in 26 min with a 100W adapter

Not many mid-range phones can claim to compete with today’s flagships, but the OnePlus 12R somehow still manages to do that. The beefy 5500mAh battery paired with the efficient Snapdragon 8 Gen 2 chip allows it to offer better battery life than some $1000 phones.

The device also has an IP64 rating and Gorilla Glass Victus 2 protection on the front. And if you’re still not convinced, it also supports 100W charging and, for US buyers, comes with an 80W adapter in the box.

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.
