The best phones to buy: How does Samsung's Galaxy S23 Ultra stack up?

Samsung's new S23 Ultra is the latest entrant in our rankings for the best phone you can buy. See how it stacks up against the best phones from Apple, Google, and even OnePlus.

Choosing the best smartphone to upgrade to can be a daunting task. Things like battery life, camera capabilities, storage space, and even health and safety features, factor into how well a new phone will fit into your mobile lifestyle.

And whether you prefer Android or iOS-based devices, it's important to factor in pricing and device longevity when shopping for a new smartphone. 

Since new models like the Samsung Galaxy S23 Ultra and OnePlus 11 are almost yearly releases, it sometimes pays to opt for an older generation phone than the latest and greatest. Not only can you save a bit of cash, but you'll also still get a lot of the same features, even if you have to sacrifice a bit of performance to do so.

Pros & Cons
Pros
  • Most complete smartphone experience money can buy
  • Reliable quad-camera setup
  • 256GB base storage leads the competition
  • Integrated S Pen stylus for enhanced functionality

Tech specs: Screen size: 6.8 inches | Storage: Up to 1TB | Processor: Qualcomm Snapdragon 8 Gen 2 for Galaxy | Panel type: WQHD+ Edge | Color: Phantom Black, Cream, Green, Lavender | Battery life: 5,000mAh | Water and dust resistant: yes 

Samsung's new Galaxy S23 Ultra is undeniably the most complete smartphone you can buy right now. It's built with a large 6.8-inch AMOLED display that produces vibrant visuals both in the brightest and dimmest environments, a reliable 5,000mAh battery, four cameras at the rear to help you capture a variety of shots, and an overclocked Snapdragon 8 Gen 2 for Galaxy chipset.

That last bit is especially important given how much more powerful yet efficient the new Ultra flagship is, even when compared to last year's S22 series. From our testing, the S23 Ultra proved to be just as good being a dedicated gaming phone as it was a regular one. The same can't be said about competing handsets, including our runner-up, the iPhone 14 Pro.

The S23 Ultra really proves its worth through unique specs and features, ones that truly matter to day-to-day usage. That includes the base storage of 256GB (versus the industry's 128GB standard), the integrated S Pen that gives you enhanced precision and inputs, Samsung's five-year commitment to security updates, and even Samsung DeX, its mobile-to-desktop service that turns your S23 Ultra into a full-on computer when connected to a monitor or TV.

Pros & Cons
Pros
  • Excellent battery life and fast-charging
  • 4K and Dolby Vision support
  • Wi-Fi 6 support
  • Satellite SOS and crash detection

The iPhone 14 Pro Max is part of Apple's newest lineup of smartphones, and it continues to prove why the company continues to dominate the mobile space. The 6.7-inch display uses Apple's Super Retina XDR panel for bright colors, finer details, and enhanced contrast. It even supports 4K resolution for video playback as well as Dolby Vision for HDR. It also has the new Dynamic Island feature, which transforms that notch of dead space on previous models omto a notification hub.

It's built with an all-new A16 Bionic processor which boosts speed and overall performance to make using the iPhone 14 Pro Max an entertainment and work hub. With support for Wi-Fi 6, you can get blazing-fast wireless internet speeds even when an LTE network isn't available. And new sensors in the phone allow it to use Apple's new crash detection feature, which automatically knows when you've been in a car accident or have fallen and contacts emergency services. It also is equipped with the new satellite SOS system, which will allow you to call for help even if you don't have LTE service.

The battery has gotten an upgrade as well, giving you up to 29 hours of use on a full charge. And with the fast-charging feature, you can get up to 50 percent battery with just 35 minutes of charging; which is perfect for when you forgot to charge overnight and need to top up on your lunch break or during a work meeting.

  • 5,000mAh battery with LTPO display

Months later, the Google Pixel 7 Pro still impresses with a camera array that features a 50MP main lens, a 48MP telephoto, and a 12MP ultrawide that shoots better low-light photography than ever before. Like last year's Pixel 6 Pro, the new Google flagship complements the improved camera hardware with its tried-and-tested computational chops, including Magic Eraser for on-the-fly content-aware fill, a new Macro Focus for enhanced zoom-in shots (up to 30x), and more. 

That's not to take away from the overall design and performance of the Pixel smartphone. The latest Pro model still features the now-iconic Pixel camera bump that beams from side to side, polished aluminum build quality, and a vivid 6.7-inch LTPO display that refreshes between 1 to 120Hz. The larger footprint also gives room for a beefy 5,000mAh battery that should keep the Pixel running for hours on end.

At $899, the Pixel 7 Pro undercuts its closest competitors, the iPhone 14 Pro and Samsung Galaxy S23 Ultra. Even then, you can expect snappy performance thanks to the Tensor G2 chip, with at least five years of consistent software and security updates. 

Pros & Cons
Pros
  • Under $450
  • OLED screen
  • Adaptive battery
  • Titan M2 security chip
Cons
  • No Wi-Fi 6 support
  • No 4K video support
  • No crash or fall detection

Tech specs: Screen size: 6.1 inches | Storage: 128GB | Processor: Google Tensor | Panel type: OLED | Color: Charcoal, Sage, Chalk | Battery life: 4,410mAh | Water and dust resistant: Yes 

If you're looking to buy a phone for your younger child or teen, the Google Pixel 6a is an excellent choice. It retails for under $500, which is great news for your budget and for parents of forgetful kids who may not be responsible enough for a more expensive smartphone. And just because the phone is budget-friendly, that doesn't mean that it skimps out on features. 

The 6.1-inch screen uses an OLED panel for better color volume and range, enhanced contrast, and improved detailing. The Google Tensor processor lets you launch apps, call, text, and video chat faster and more easily while the Titan M2 chip and Tensor security core protect the phone from spying and hacking.

With 128GB of internal storage, there's plenty of space for photos, videos, apps, and documents. And if you need more room, you can sync your phone to your favorite cloud storage service to free up your local drive. The phone is also water resistant up to 4 feet, so you won't have to worry about rain, sweat, or spills ruining the phone. 

Read the review: Google Pixel 6a review

The battery has an adaptive power mode, which automatically reduces power consumption when the phone isn't being used, which boosts the battery life to about 24 hours. This is especially handy since you and your kids won't have to remember to keep a charging cable handy while at work or school.

Pros & Cons
Pros
  • Snappy and smooth performance
  • 100W fast-charging (80W in the US) with charger in the box
  • Premium build quality for the price
  • Competitive main camera for photos
Cons
  • Storage and RAM configuration is limited to 128GB/256GB
  • No wireless charging
  • No IP68 rating for water and dust resistance

A slow-charging phone can be a real pain point, especially if you're always on the go. That's why the OnePlus 11 carves out its own best category, beating Apple, Google, and even Samsung when it comes to charging speed. The latest model comes with 100W SuperVooc fast charging or 80W in the US, which is still great. For reference, the highest-end iPhone 14 Pro Max has a charging speed limit of 30W and Samsung's just-released Galaxy S23 Ultra caps out at 45W. Both of those devices take a least an hour to go from 0% to 75% battery.

The OnePlus 11 can go from empty to full in less than 27 minutes. That charging speed, and the fact that OnePlus includes its proprietary charger in the box, is game-changing.

Read the review: OnePlus 11

The best part is that the rest of the phone is no slouch either; you're getting a 6.7-inch AMOLED display with 120Hz refresh rate, the latest Snapdragon 8 Gen 2 processor, a 5,000mAh dual-cell battery, and a competitive triple-camera array that gets the job done. In total, OnePlus is charging you a starting rate of $699, which is just as good of a value pickup as the best budget smartphone on this list.

Pros & Cons
Pros
  • Cover screen for notifications
  • Incredibly compact
  • Water and dust resistant
  • Form factor lends itself to creative camera use cases
Cons
  • Smaller battery than most handsets
  • Folding form causes a crease in the screen
  • Undeniably more fragile than the typical slab phone

Flip phones have made a (somewhat) triumphant return with the Samsung Galaxy Z Flip 4, once again letting you sassily hang up on someone by snapping the phone shut while also bringing the form factor up to speed with modern expectations. The Flip 4 is incredibly compact when folded, about 3 inches square, making it perfect for slipping into your pocket, purse, or travel bag. It also features a cover screen to provide quick, easy-to-read alerts for phone calls, texts, and app notifications without needing to open your phone. 

And not only is the Flip 4 compact, but it's also water and dust-resistant, so rain, sweat, and everyday use won't be an issue. The screen uses Corning Gorilla Glass to protect against cracks, scratches, and chips while still giving you complete control over your apps and phone. And if you can't live without a virtual assistant, the Flip 4 is compatible with Samsung's Bixby as well as Alexa, and Google Assistant to give you hands-free control over your new phone.

The previous generation of iPhones is still a great option if you're looking to upgrade, but aren't concerned with having the latest and greatest models. The iPhone 13 Pro offers up to 1TB of internal storage for apps, photos, videos, and music, but if you somehow need more room, you can sync your phone to iCloud to free up local drive space. The 6.1-inch Super Retina XDR display gives you incredibly lifelike images with great color volume and detailing that's perfect for photography as well as streaming videos and video chatting with friends and family.

The A15 Bionic processor chip isn't quite as fast as the new iPhone 14, but still lets you quickly and efficiently multitask, launch apps, text, and call. The integrated battery gives you up to 22 hours of use on a full charge, letting you go all day before you need to even think about plugging in.

Which phone is right for you?

Choosing a phone can be a daunting task. But having a list of your must-have features can go a long way toward narrowing down your options. If you're a mobile professional or travel a lot for work, you'll want to choose a phone that can provide you with at least a full day of use on a full battery as well as both LTE and Wi-Fi connectivity. 

If you're looking for your teen's first smartphone, a budget-friendly and less feature-heavy option may be better to prevent overspending as well as misuse. And if you're a content creator or other creative professional, you'll want a phone with an excellent front and rear camera to capture photos and videos for your social media feed.

How did we choose these phones?

The process to make our phone selections includes testing the phones for weeks, researching reviewer guides and manufacturer websites, talking with colleagues and other users who have hands-on experience with the smartphones, and then selecting the best from all of the available choices. 

Over the past year, we tested new phones from Google, Samsung, Apple, OnePlus, and several others.

Which phone has the best camera?

It's debatable between the iPhone 14 Pro, Google Pixel 7 Pro, and Samsung Galaxy S23 Ultra. For long-distance shots, Samsung's 200MP rear camera with 100x Space Zoom can capture subjects as far out as the moon. For point-and-shoot pictures and a rather simplified (but effective) camera experience, Google's Pixel phones have always been at the top. If you're a videographer at heart, then the iPhone 14 Pro, with Cinematic mode and Action mode, makes for an excellent tool to get the shots you need.

How long should a phone battery last?

The average phone battery gives you about 22 hours of use on a full charge, which is great for staying connected on your commutes, work flights, and at home in the evenings. But that's just the average, actual use time varies by phone model and by what you're using your phone for. 

For example, the latest iPhone 14 Pro Max boasts a 29 hour battery life. But you'll most certainly get less than that if you habitually scroll through social media or stream video and music. And the Samsung Galaxy Z Flip 4 has just a 9 hour battery life, which is further reduced by streaming, social media, and making calls.

How much storage should my phone have?

Most smartphones have a base storage capacity of 128GB, which is plenty of space for average users to download apps and music, take photos, and shoot video. However, if you're a mobile or creative professional, you'll need more space. Many smartphones have expanded storage options up to 512GB or even 1TB, and you can always sync your phone to your preferred cloud storage service to free up local storage space.

Which phones are also worth considering?

If you're in the market for a new smartphone, there are tons of options out there. Whether you're looking to upgrade or get your first smartphone, Apple, Samsung, and OnePlus have great choices:
