The 10 phones with the best battery life

0


For all the smartphone advancements over the last few years, one thing has remained stubbornly consistent: battery life.

With fast processors, fluid displays and demanding apps, even large capacities can struggle to deliver good battery life. If your phone lasts for a full day on a single charge, that’s still considered good.

But what if instead of it being one of many important things about a smartphone, battery life was your number one priority? If that sounds like you, this is the round-up you need to pay attention to.

We test every single Android phone we review using the PCMark battery test, which simulates real-world usage at a fairly typical 200 nits of brightness. Most of the time, a higher figure in this test correlates to better battery life.

The app isn’t available for iOS, but we didn’t want to rule out every single iPhone. So as a compromise, we’ve added the iPhone we’ve tested with the best battery life in our experience.

One thing we aren’t taking into account here is charging speeds. If battery life is disappointing, getting back to 100% within half an hour of being connected is a great trade-off.

Also, if you literally only care about great battery life, some basic phones last a week or even longer.

But if a smartphone with outstanding battery life is what you’re after, these are phones to get.

Best battery life phones 2024

1. Sony Xperia 10 IV – Best overall

Pros

Stellar battery life 

Practical lightweight design 

Crisp OLED screen 

Cons

No 120Hz refresh rate

Patchy camera

Slow charging

Battery test score: 24:52

Battery capacity: 5,000mAh

This phone is by no means the best overall phone you can buy. But if it’s battery life you really want, in a fully capable Android phone with the Google Play Store, the Sony Xperia 10 IV blows all competition out of the water. In the PC Mark battery test it scored 24 hours and 52 minutes – an utterly incredible score that beats the second place phone in this chart by several hours.

It means the Xperia 10 IV is the only phone we’ve tested that could truly stretch to three days between charges if you are a light user.

That’s all the more impressive considering it’s only 8.3mm thick. Add to that IP68 water and dust resistance and a 3.5mm audio jack, alongside an eye-catching 6in screen with a tall 21:9 aspect ratio for watching full-screen movies,. and you’ve got a solid mid-range phone.

It charges slowly, the cameras aren’t the best, and it’s a little dull overall – but the battery is the best in the business.

While we have reviewed the newer Xperia 10 V, it wasn’t tested using PCMark.

2. Oppo A78 5G – Great budget option

Pros

Good performance for the price

Nice 90Hz display

Superb battery life

Cons

Average cameras

Loads of bloatware

Cheap build

Battery test score: 21:08

Battery capacity: 5,000mAh

The Oppo A78 5G might be cheap, something which shows in its cheap build quality and average cameras, but it doesn’t skimp on battery life. If there was a metric of the most battery life for your money, this would be the phone to beat.

There are other things to like about the phone, too, including an attractive 90Hz display and decent enough performance to get you through your day. If you’re looking for something reliable while out and about, but don’t need all the bells and whistles of more expensive handsets, it’s a good choice.

3. Realme 9 Pro – Very good display

Pros

Long-lasting battery

Smooth, simple software

Snazzy design

120Hz refresh rate

Cons

Inconsistent camera

No IP waterproofing

Average performance

LCD panel

Price When Reviewed:

Battery test score: 18:30

Battery capacity: 5,000mAh

Don’t count out any of the phones on this list just because the Sony there is at the top. At £299 in the UK, this Realme phone is another amazingly long-lasting phone to consider.

It has a simple design and software to match but still crams in a high refresh rate 120Hz screen for the money, albeit an LCD one. As is the case with many long battery life phones, it has fairly mediocre performance , but this puts less stress on the battery.

The camera isn’t great and there’s no waterproofing, so you may want to consider spending a little more. But if those things don’t bother you, this is a very affordable way to leave your charger at home and not worry.

4. Asus Zenfone 10 – Best small phone

Pros

Distinctive, compact design

Fantastic battery life

Strong specs

Headphone jack

Cons

Camera is only mid-tier

Only two Android updates promised

Price When Reviewed:

$699.99

Battery test score: 17:36

Battery capacity: 4,300mAh

The Asus Zenfone 10 is the most compact flagship-level smartphone out there, so we are astounded at how good its battery life is. In our testing, we found the battery was regularly hovering around 50% at the end of a normal day’s use – that’s mighty impressive.

Aside from only two years of software updates, this phone ticks all the boxes. Great design with a paper-like rear finish (as opposed to slippery glass), premium performance, great cameras and Asus’s tasteful take on Android.

It’s a great battery life phone that actually fits in your pocket and even has features (like a 3.5mm headphone jack) that most bigger phones dropped because of the supposed lack of space. It’s worth taking a look at the Zenfone 10 for that reason alone.

5. Apple iPhone 14 Plus – Best iPhone battery life

Pros

Top-tier performance

Excellent cameras

Great battery life

Relatively lightweight

Cons

Too expensive

Only a 60Hz display

Slow charging

Price When Reviewed:

From $899

Battery test score: N/A

Battery capacity: 4,323mAh (unconfirmed)

The 14 Plus is the hardest iPhone 14 model to recommend, but battery life is the big thing in its favour. This is a phone that can comfortably last two full days of normal use, and potentially stretch to three if you only use it occasionally.

And there’s a lot to like elsewhere, from excellent A15 Bionic performance to some of the best cameras you’ll find on any smartphone. At 203g, it’s also quite light for a phone with a 6.7in display – it’s just a shame that’s still a 60Hz panel rather than 120Hz on the Pro models.

With slow charging and a high price tag, there are better iPhones out there for most people – including the newer iPhone 15 models. But if battery life is your top priority, the iPhone 14 Plus is still a great choice.

6. Realme 9i – Best value for money

Pros

Nice design

128GB storage as standard

Long battery life

33W fast charging

Cons

Average performance

No 5G

Only 4GB of RAM

Price When Reviewed:

Unavailable in the US

Battery test score: 16:49

Battery capacity: 4,880mAh

The Realme 9i is cheapest phone on this list, but it still has excellent battery life. We’re talking well into a second day of usage before needing to reach for the charger.

As you might expect, there are compromises in other areas. The Realme 9i doesn’t have 5G, performance isn’t great and there’s only 128GB of storage. But its plastic build still looks good, and charging is surprisingly fast.

You also get USB-C and a 3.5mm headphone jack. The screen isn’t quite Full HD and LCD rather than OLED, but you do get a nice 90Hz refresh rate.

Don’t expect to be able to play high-end games, but if battery is your number one concern then this is the cheapest way to get excellent battery life on a phone right now.

7. Oppo Find X6 Pro – Best cameras

Pros

Incredible main camera

Very good display

Strong battery life and charging

Top-notch performance

Cons

ColorOS isn’t great

No official warranty outside China

No Google Play Store

Battery test score: 16:43

Battery capacity: 5,000mAh

The Oppo Find X6 Pro is the best camera phone that also has great battery life. Beneath the distinctive design, you can expect stellar performance and one of the finest rear camera sensors on any smartphone.

However, as it’s a China-only phone, the Find X6 Pro doesn’t run Google services out of the box, and the software is too skewed to the Chinese market’s preferences to recommend to anyone outside of China. We’re talking bloatware, unnecessary features and just too much clutter.

That’s the main reason it’s lower down this list, but it’s still worth considering for the combination of battery life and cameras.

8. Samsung Galaxy S23 Plus – Best Samsung for battery life

Pros

Outstandingly fast

Solid, versatile cameras

Excellent battery life

Five years of software support

Cons

45W charging not quite top tier

Expensive

Samsung’s software has its quirks

Price When Reviewed:

From $999

Battery test score: 15:47

Battery capacity: 4,700mAh

Rather than some regions getting Samsung’s own Exynos chips, all of the Galaxy S23 flagships use Qualcomm’s Snapdragon 8 Gen 2 everywhere. Not only does this deliver great performance on the S23 Plus, but its power efficiency also helps ensure great battery life.

In our experience, the phone can last well into a second day of regular usage, which is a key advantage over the S23 Ultra. Alongside a versatile triple rear camera system, great 120Hz OLED display and the premium design we’ve come to associate with Samsung flagships, there’s a lot to like here.

This is a phone to buy if you want top specs but don’t want to compromise on battery or software.

9. Realme 11 Pro+ – Great value

Pros

Great main camera

Two-day battery life

Speedy charging

Beautiful 120Hz AMOLED screen is beautiful

Cons

No IP rating

Mediocre performance

No wireless charging

Battery test score: 15:38

Battery capacity: 5,000mAh

If you’re someone who loves photography but doesn’t have the budget to buy a premium smartphone, the Realme 11 Pro+ is the phone for you. This is the best camera phone Realme has ever made, and its quality for the price is frankly astonishing.

Of course, there are some trade-offs, such as no IP waterproofing certification or the lack of wireless charging. However, given how long this phone lasts on a charge, neither of these should be dealbreakers.

The display is superb too, with average performance the only real reason to look elsewhere. But for the money, the Realme 11 Pro+ is great value.

10. Redmagic 8 Pro – Best battery life gaming phone

Pros

Phenomenal performance

Built-in fan

Impressive battery life

Reasonable price

Cons

Big and heavy

No water resistance rating

No wireless charging

Price When Reviewed:

$649

Battery test score: 15:35

Battery capacity: 6,000mAh

If you want great battery life for playing mobile games, then you might want to get a phone that is specifically designed for gaming.

Nubia’s Redmagic 8 Pro is your best option right now – and it’s not even that pricey. It has the largest battery on this list at 6,000mAh – achieved by using two separate 3,000mAh cells.

There’s a fast charger in the box, so you can easily refill its battery. It charges to 51% in just 30 minutes. There’s also a fan built-in to keep things cool while playing all those games.

A downside is the lack of creature comforts. You’ll have to say goodbye to your water resistance and wireless charging, plus deal with the add bulk of a gaming phone. However, if you don’t mind these things, it’s certainly a great choice for mobile gamers.

FAQ
1.
How is battery capacity measured?

Battery capacity is measured in milliamp-hours (mAh). The higher the mAh of a battery, the higher its technical capacity. But the phones with the highest mAh aren’t always the phones with the best battery life.

It can depend on how efficient the phone’s processor is in conjunction with the software, as well as how much you actually use your phone. Expensive high-end phones often are faster and have better screens, but require larger batteries to compensate or suffer from crippling shortfalls.

2.
What should you look out for?

When choosing a phone, it’s important to consider what you’ll likely use it for primarily and the hardware that it brings to the table. If you buy a larger-screened phone with a high-resolution display and a high peak brightness, those attributes are all going to affect longevity negatively compared to a phone with the same-sized battery but a smaller or lower resolution panel, for example.

Some phones – particularly in the mid-range and budget segments – may offer large batteries and great battery life but forgo or offer underwhelming fast-charging speeds, meaning recharging them at any time other than overnight may become a chore.

Decent fast charging speed wattages to look out for as of 2022 are anything over 33W, with some devices boasting 120W and beyond, at the top end of the current range.

3.
What do the results show?

For consistency’s sake, we’re only including phones which have been tested using our most current benchmarking process, which relies of PC Mark’s Work 3.0 battery test to generate a score. The only exception is iPhones, which don’t support this app, so we do our best to factor those into the ranking based on real-world testing and experience.

It’s worth noting that these tests spit out a figure in minutes and seconds, but this is not an indication of how long a phone will actually last. 

In all tests, the screen brightness is set to the same level to ensure fairness and consistency (200cd/m2). The phone discharges its battery and the screen is set not to dim or turn off.

For example, if a phone lasts 12:15 in a test, it lasted 12 hours and 15 minutes with the screen on and the test processes running. These figures may vary from a device’s own report of screen-on time, as usage and power management setups have an additional effect on real-world situations.
