I spent the weekend trying Polaroid's new Flip instant camera with sonar autofocus

Instant cameras have been all the rage over the past few years. Whether it's taking a step back from relying on your smartphone or just finding joy in the spontaneity that is a physical film print, there's a lot to love about these retro cameras. But there are some downsides: Mainly, messing up a photo is far more costly than snapping a digital picture on your iPhone. Today, the Polaroid Flip hits store shelves with the company's first sonar-backed autofocus system in decades, designed to make it easier to get the perfect shot.
Polaroid Flip Instant Camera
Polaroid's latest instant camera has many of the signature features I've come to expect from the brand. It supports Polaroid i-Type and 600 film, has Bluetooth support for connecting to a companion app and rocks a classic retro-inspired design — all with new enhancements like a sonar autofocus system and brighter flash. The new Polaroid Flip is as simple as it gets for an instant camera. You get a prominent red shutter button, eight exposures per film pack and a flip-up lid that turns on the gadget. That flippable design does more than just give the Flip its name. It also houses new technology, making this a far better option for those who only want to point the camera at a subject and print a good photo.
Polaroid's latest may be the newest camera on the block, but it also relies on the company's legacy technology to achieve that true point-and-shoot focus. Housed in the top lid is the flash, and below it sits the headlining feature — a sonar sensor. Like I said above, the Flip is the first of the company's releases to use the tech in over a decade. In its application here, the camera relies on sonar to measure the distance between the camera and your subject before switching between one of four focus points best suited to deliver an in-focus photo. It also means that the autofocus system works in low-light scenarios. This all lessens the odds that you'll print out a blurry shot, or worse, fuss with the manual settings to dial in an exposure.
Circling back to everything else packed into the lid, the Polaroid Flip's canopy folds down to protect the lens and turn off the camera when not in use. It houses the flash, which is the company's brightest in a modern instant camera. This is bright enough to illuminate subjects over 14 feet away and can be controlled via a companion app if you'd like to tone it down. Speaking of the app, the camera's Bluetooth support can pair with a smartphone to tweak other settings like aperture and shutter speed. While not the main selling point of the camera, it gives photographers the choice of customizing shots if they want to.
My favorite part about the Polaroid Flip is its sonar-based autofocus system, so I wanted to spend a bit more time explaining how it works. The instant camera has two lenses that are split into four preset focus points to coincide with specific distances: 0.65m, 0.85m, 1.2m and 2.5m. Polaroid also backs that with a new scene analysis feature that warns you with a red LED light in the viewfinder when an image is overexposed, underexposed or if there are focus issues.
A half-press of the shutter button fires up the sonar sensor, which beams out to see how far away the subject is. Then, the camera's fixed lenses shift between those four focus points to find the best tool for the job. All that's left to do is fully press the shutter, and your print will pop out of the front.
While we've yet to review the new Polaroid Flip in its entirety, I spent the past weekend with it and jotted down some noteworthy thoughts. Last year, I purchased Polaroid's first manual instant camera, the I-2, and have had a complicated relationship with it. Dialing in a picture is satisfying, but I rarely want to go through the effort just for an instant film print. If I were going to do that, I'd be shooting with proper film. So for an instant camera, I've learned the hard way that I'd rather press the shutter and receive a print, not spend a minute or two fussing with the controls.
Polaroid's Flip is the exact opposite of the I-2 I've grown to dislike. The former has been fun and effortless to use, so much so that I let my partner take a crack at shooting some prints. She is by no means a photographer, but she was able to take some solid photos. That ease of use is what I was looking for from the Flip, and it did not disappoint.
I'll be excited to see what my testing colleagues at CNN Underscored think once they inevitably get their hands on the Polaroid Flip. Our current best-tested instant camera pick, the Fujifilm Instax Mini Evo, has the same $200 price tag as this new release. That makes all the tech and the ease of use factor packed into the Polaroid Flip a better buy in my book. Though, I'll have to wait and see if the Flip shakes up our guide in the coming months after a longer-term testing session.

I just spent my first 48 hours with iOS 26 — here's what happened

iOS 26 won't be on iPhones officially until later in the year. But for developers — or the keen and reckless — a beta is already available to try out its new features. And once I had cleared enough old video and music to make space for the download, I made the upgrade from iOS 18 to Apple's latest iOS 26 developer beta. I haven't done this with a goal of judging iOS 26's various new elements as good or bad — betas aren't ever fully representative of the final product (or at least shouldn't be). And besides, a public beta that's more appropriate for average users is still to come, with Apple promising a July release. Instead, my aim in taking the iOS 26 developer beta out for a spin is to see how the new software changes the way my iPhone 16 Pro Max feels to use and to get a baseline measurement of the new features ahead of the full release that's slated for the fall. Two days' worth of use hasn't been enough time to try all of Apple's additions. But I have sampled the features that matter the most to how I use my iPhone, and it's been a surprisingly significant change, even for a brand new iOS. I can't tell you if it's right for you to download a beta version of iOS 26, but I can at least explain what it's like if you've not tried it for yourself. I was excited to see the new Liquid Glass design in action just after the installation process, but I was surprised just how quickly it appeared. The "Hello" screen that pops up any time you update the OS of an Apple product has a new glassy style, providing a fun visual overture for the iOS 26 experience you're about to embark on. In terms of the lock and home screens, the change is actually more subtle than I expected. Seeing my home screen before and after the update shows that apps have new icons and that app folders are now more transparent. But I was a little underwhelmed by the new look, at least at first. The real difference appears when the interface is in motion. Swiping between screens, tapping or long-pressing an icon brings the Liquid Glass to life, with the dynamic refractions making the background warp as you move. It's seriously impressive to watch. Get instant access to breaking news, the hottest reviews, great deals and helpful tips. Personally, I've not had much issue using the new interface with its many transparent elements. But I'm glad that Apple thought ahead and has a reduced transparency option for users who find it harder to make out elements like the Control Center over busy wallpapers, apps or home screen layouts. One of the first changes I made for myself in iOS 26 was to take advantage of the new scaleable clock for the lock screen. Setting up the iOS 26 custom wallpaper at the same time, I now have a completely refreshed display with a much more readable clock. I'm not sure how much I like the lock screen widgets being moved to the bottom of the screen in this iteration, but hopefully that's something that I can adapt to in time or alter in the final version. The second stage of trying iOS 26, after the initial one of admiring the OS's new look, is discovering the deeper changes made to familiar apps and features as you start using them. One example would be the screenshot menu. This now contains options to use Visual Intelligence on what you've captured, similar to Circle to Search on recent Android phones. It's an addition that promises to be potentially useful. But going even deeper than that, screengrabs on iPhone don't have to pop up with the full menu each time. You can instead set screenshots to pop up as a thumbnail in the corner of the display, disappearing into your photo gallery if you don't interact but opening the full editing and sharing interface if you want it. It's similar to the way many Android phones treat their screenshots, and it's a smart idea for Apple to make its own. Safari's new look in iOS 26 is quite striking. Not only because of Liquid Glass making the menu much more translucent, but also the new Compact display mode hides almost all controls to give the websites you browse the maximum amount of space. This was too much of a change for me, but fortunately Apple allows you to switch with the more familiar Bottom and Top modes, which still look fresh but navigate in a more familiar way. Apple's resurrected Games app landed itself on my home page, and I'm happy to see it return. Apart from acting as a hub for games I already have downloaded, it provides a brilliant showcase for games I haven't played but have yet to come across. In fact, the Games app led to me downloading demos for two games on the same day. And while this article is meant to be all about iOS 26, I have to endorse Duck Detective and A Little To The Left as two cute but brain-stretching puzzle games that are well worth your time. Some of the subtler changes to iOS 26 require more time to observe. That includes Apple Music's AutoMix, which places automated transitions between each song as other music streaming services offer. It's seamless like you'd hope it to be, and gives a nice sense of cohesion to playlists of varied tracks. It's a little odd when it appears in familiar albums though, probably because I'm used to the static transitions these often have. The Camera app is effectively no different than before if you pull your iPhone out for a quick snapshot. The shutter button's still in the bottom center, and your camera zoom options above it. But if you want to change any other settings, you'll have to interact with the new menu bar and hidden icons for timer or aspect ratio options. This does look neat, but it'll there will be a learning process for anyone who's been regularly using their iPhone's camera over the last decade. Apple took a similar approach with updating the Photos app, using three top-level navigation tabs to direct users. But unlike with Camera in iOS 26, this change actually puts more up-front than the previous software version, iOS 18. Easy switching between your collections and album and the camera roll has returned, and I imagine lots of people, myself included, will be excited to gain their previous image navigation options back. I've not yet had a look at everything iOS 26 has to offer. But I'm excited for the first time I get to see Hold Assist or Call Screening in action, or try out Live Translation on my next vacation. Plus, Apple Maps' new commuting alerts and Visited Places menu have piqued my interest, and I'm hoping that over time, its personalization powers will be able to rescue me from otherwise bad trips to work. Of course I should emphasize once more that this is currently a developer beta, which means you need an Apple Developer account and either a spare iPhone or a really good reason to install it on your main device. We have a guide on installing the iOS 26 developer beta if you need it, but I'd recommend most readers wait until the public beta comes in July, or until the stable release appears as an automatic update this fall.

I tested 10 flagship phones. This one has the best battery

When it comes to selecting the best phones, three key areas are most important. The display and the best smartphone camera are integral parts of the experience on most phones — especially with the display on the best folding phones — but battery life is important to every smartphone user. Between different types of battery technology and a lot of variety in capacity and charging speeds, there's a lot to take into consideration when evaluating the best smartphone battery life, especially as usage patterns vary so wildly as well. Recommended Videos Yet, the question remains unanswered: which phone has the best battery life and charging? Since the iPhone launch last year, I've been testing the best phones as they've come into my possession. I've tested over 50 phones — folding and non-folding — over the past year, and here's what I've found. Understanding battery technology Before we dig into the testing, a quick primer on battery technology. For almost three decades, the smartphone industry has been using lithium-ion batteries to power phones and other electronic devices that require a battery. The next generation of smartphone batteries uses Silicon Carbon technology, which offers higher energy density, faster charging capabilities, and potentially a longer lifespan. This means you can fit a bigger battery in the same-sized phone or a bigger battery in a thinner device, making it ideal for the best thin phones. The first smartphone with a Silicon Carbon battery was the Honor Magic V5 Pro, which was introduced two years ago. Since then, we've seen many other Asian phone makers launch phones that utilize this battery technology. Samsung, Apple, and Google have yet to follow suit, but OnePlus launched the OnePlus 13 in January, making it the first smartphone in the US to utilize this architecture. Curating the best phones for testing There are so many phones released each year, both inside and outside the US, that testing every single device wouldn't be feasible, at least not for this mid-year test. However, the data I collected over the past year, combined with my own subjective experiences with each device, means it's possible to calculate which phones to include in these tests. To simplify the testing and results, I've split the shortlist into two categories: candybar phones and the best folding phones: Here's a quick overview of the key battery specs for the shortlist: Battery Size (mAh) Battery Type Charging Speed (W) Apple iPhone 16 Pro Max 4,685 mAh Lithium-Ion 37W Samsung Galaxy S25 Ultra 5,000 mAh Lithium-Ion 45W Samsung Galaxy S25 Edge 3,900 mAh Lithium-Ion 25W Google Pixel 9 Pro XL 5,060 mAh Lithium-Ion 37W OnePlus 13 6,000 mAh SIlicon Carbon 80W Motorola Razr 60 Ultra 4,700 mAh SIlicon Carbon 68W Samsung Galaxy Z Flip 6 4,000 mAh Lithium-Ion 25W Samsung Galaxy Z Fold 6 4,400 mAh Lithium-Ion 25W Google Pixel 9 Pro Fold 4,650 mAh Lithium-Ion 21W Oppo Find N5 5,600 mAh SIlicon Carbon 80W How I tested these phones I have been reviewing phones for almost twenty years, and have been objectively testing phones since 2015. To reduce the number of variables, I ensured that these tests were run after a factory reset, with a specific test account installed on the phone. This helped limit any potential data corruption caused by a particular app or background data usage. Each phone underwent the same testing. Each test was conducted with the display set to 200 nits of brightness to minimize variations caused by auto-brightness or different display brightness controllers. For the folding phones, the tests were conducted on the cover display. To test the phones, I charged each to 100% and then ran various tests. The first involved browsing a looping set of websites and social feeds, while the second ran the same test, but with a looped video. The gaming test involved playing Genshin Impact for 60 minutes and extrapolating battery usage from there. The best battery life for web browsing and social media Let's first take a look at the results of the browsing and social media test for each of the five non-folding phones: Rank Phone Capacity Duration Points 1st Motorola Razr 60 Ultra 4,700 mAh 15:48 h 10 2nd Apple iPhone 16 Pro Max 4,685 mAh 15:42 h 9 3rd OnePlus 13 6,000 mAh 15:02 h 8 4th Google Pixel 9 Pro XL 5,060 mAh 11:58 h 7 5th Oppo Find N5 5,600 mAh 11:25 h 6 6th Google Pixel 9 Pro Fold 4,650 mAh 11:01 h 5 7th Samsung Galaxy S25 Ultra 5,000 mAh 10:57 h 4 8th Samsung Galaxy S25 Edge 3,900 mAh 8:59 h 3 9th Samsung Galaxy Z Fold 6 4,400 mAh 8:58 h 2 10th Samsung Galaxy Z Flip 6 4,000 mAh 7:59 h 1 The biggest surprise through all of this testing is just how capable the Motorola Razr 60 Ultra battery proves to be. In this test, it outranks the iPhone 16 Pro Max, which lasted considerably longer than any other phone since the iPhone 15 Pro Max. Both of these devices outperform your expectations based on their capacity, whereas the opposite is true of the Galaxy S25 Ultra, which should be better. The best battery life for video playback Of course, web browsing and social media playback is only one test, albeit the most varied one I tried. A more strenuous test is video playback, especially as it engages the graphics card more strenuously than the simpler first test. Rank Phone Capacity Duration Points 1st OnePlus 13 6,000 mAh 23:21 h 10 2nd Apple iPhone 16 Pro Max 4,685 mAh 23:04 h 9 3rd Motorola Razr 60 Ultra 4,700 mAh 19:22 h 8 4th Samsung Galaxy S25 Ultra 5,000 mAh 18:42 h 7 5th Samsung Galaxy S25 Edge 3,900 mAh 16:58 h 6 6th Oppo Find N5 5,600 mAh 15:01 h 5 7th Samsung Galaxy Z Fold 6 4,400 mAh 14:58 h 4 8th Google Pixel 9 Pro Fold 4,650 mAh 14:31 h 3 9th Samsung Galaxy Z Flip 6 4,000 mAh 14:21 h 2 10th Google Pixel 9 Pro XL 5,060 mAh 14:02 h 1 The OnePlus 13 unsurprisingly outperforms the competition here, as the larger capacity and software optimizations work their magic. The iPhone 16 Pro Max meets expectations here as Apple's software and hardware integration proves to be magical for endurance. It'll be interesting to see how the new background tasks feature in iOS 26 affects this. I'm very impressed by the Galaxy S25 Edge here, as it has the smallest battery in this list — unsurprising as it's the thinnest non-folding phone — but it ranks 5th in one of the more strenuous tests. If you watch a lot of movies, this phone will likely handle what you throw at it. The best battery life for gaming The first two tests have become progressively more strenuous, but how does each phone endure when tested under heavy gaming conditions? Where applicable, I enabled game mode (or a similar feature) but left the settings at their default values. Rank Phone Capacity Duration Points 1st Samsung Galaxy S25 Ultra 5,000 mAh 9:42 h 10 2nd Apple iPhone 16 Pro Max 4,685 mAh 9:38 h 9 3rd Oppo Find N5 5,600 mAh 7:58 h 8 4th Motorola Razr 60 Ultra 4,700 mAh 7:42h 7 5th OnePlus 13 6,000 mAh 7:13 h 6 6th Google Pixel 9 Pro XL 5,060 mAh 7:03 h 5 7th Samsung Galaxy Z Fold 6 4,400 mAh 6:58 h 4 8th Google Pixel 9 Pro Fold 4,650 mAh 6:40 h 3 9th Samsung Galaxy S25 Edge 3,900 mAh 6:03 h 2 10th Samsung Galaxy Z Flip 6 4,000 mAh 6:02 h 1 I was taken aback by the Galaxy S25 Ultra's results here, but a retest revealed similar results, so this is a clear example of how a feature like Samsung's Game Booster can extend your battery life under heavy gaming conditions. This is made even more surprising, given that it shares the 8-core Snapdragon 8 Elite processor with the OnePlus 13, albeit Samsung has developed an optimized version of the processor for its flagship devices. The iPhone proves to be an endurance champion yet again, and the Find N5 and Razr 60 Ultra both continue to prove that folding phones can offer better battery life than non-folding phones. The rest of the results are as I expected: the Pixel 9 Pro Fold, Z Fold 6, and Flip 6 all rank low in most of the tests. Before we head to the charging tests, here's a quick look at the overall top 3 in the battery tests: iPhone 16 Pro Max (27 points), Motorola Razr 60 Ultra (25 points), and OnePlus 13 (24 points). The phones that charge the fastest Of course, when your battery is running low, you need fast charging, so which of these phones charges the fastest? First, a quick note about mAh/min. It's a metric I have been using for years, and it's designed to standardize charging speeds while eliminating the variability of battery capacity and charging speed. It also applies to the 15-minute reading, where we record the battery percentage reported by the phone and multiply it by the capacity to estimate the mAh charged during those 15 minutes. Let's take a look, first, at the time taken for a full charge: Rank Phone Speed Full charge m/Ah min Points 1st OnePlus 13 80W 35 mins 171.4 10 2nd Oppo Find N5 80W 50 mins 112 9 3rd Motorola Razr 60 Ultra 68W 48 mins 93.8 8 4th Samsung Galaxy S25 Ultra 45W 64 mins 78.1 7 5th Google Pixel 9 Pro XL 37W 78 mins 64.9 6 6th Samsung Galaxy S25 Edge 25W 67 mins 58.2 5 7th Samsung Galaxy Z Fold 6 25W 91 mins 48.4 4 8th Google Pixel 9 Pro Fold 21W 105 mins 44.3 3 9th Apple iPhone 16 Pro Max 37W 114 mins 41.1 2 10th Samsung Galaxy Z Flip 6 25W 102 mins 39.2 1 For more than a decade, one thing has been clear: companies like Huawei, Oppo, Honor, and OnePlus have all figured out how to recharge phones quickly and safely. This has been the case since long before the introduction of the new generation of Silicon Carbon batteries, and the technology is significantly faster than its competitors. The result is that it's no surprise that OnePlus and Oppo dominate the list. However, the biggest surprise comes from the Motorola Razr 60 Ultra and its new 68W charging, which significantly increases charging speeds. I don't know about you, but I often forget to charge my phone, or the battery runs low when I only have a short moment to recharge. For those times, I also noted the percentage each phone added to the battery after a 15-minute charge. Rank Phone Speed % at 15 m ~mAh Points 1st OnePlus 13 80W 55% 3,300 10 2nd Oppo Find N5 80W 42% 2,352 9 3rd Motorola Razr 60 Ultra 68W 48% 2,160 8 4th Samsung Galaxy S25 Ultra 45W 40% 2,000 7 5th Google Pixel 9 Pro XL 37W 35% 1,771 6 6th Apple iPhone 16 Pro Max 37W 27% 1,265 5 7th Samsung Galaxy S25 Edge 25W 30% 1,170 4 8th Samsung Galaxy Z Fold 6 25W 26% 1,144 3 9th Google Pixel 9 Pro Fold 21W 24% 1,116 2 10th Samsung Galaxy Z Flip 6 25W 23% 920 1 This overall charging test is when Apple's core weakness becomes apparent. The battery life of the iPhone 16 Pro Max is fantastic, but the charging speeds leave much to be desired. As you'll see below, however, this is not always the case, and the slower overall iPhone charging speeds are usually due to the device charging more slowly (to protect the battery) once it reaches 80%. The phone with the best battery is… There's a lot more testing to do on these phones and many of the best upcoming folding phones like the Galaxy Z Fold 7 and Galaxy Z Flip 7, but where do Samsung's current folding phones stand? How about the new Galaxy S25 Edge? How does the thin body affect that battery compared to its beefier sibling? Let's look at the final results to find out! Rank Phone Total Points 1st OnePlus 13 44 2nd Motorola Razr 60 Ultra 41 3rd Oppo Find N5 37 4th Samsung Galaxy S25 Ultra 35 5th Apple iPhone 16 Pro Max 33 6th Google Pixel 9 Pro XL 25 7th Samsung Galaxy S25 Edge 21 8th Samsung Galaxy Z Fold 6 17 9th Google Pixel 9 Pro Fold 16 10th Samsung Galaxy Z Flip 6 6 It's no surprise that the Galaxy Z Flip 6 comes last, especially given it's been there for most of these tests, but it does have me curious whether they'll be able to improve it in the upcoming Z Flip 7. The Galaxy S25 Edge performs admirably given the capacity constraints, especially as it has the smallest battery of all. In the top 5, Apple is the most interesting. Improving charging speeds would eliminate the gap to the top of the leaderboard, especially since it currently ranks first in the battery life tests. The Galaxy S25 Ultra is a solid contender, but it shows that there's still room for Samsung to improve. The top 3 are very interesting. The Oppo Find N5 has the best book-style folding phone battery life that I've tested, and this rings true in the testing. The same applies to the Razr 60 Ultra, which proves that flip phones can be just as capable as non-flip ones. I'm very surprised by just how capable the Razr 60 Ultra battery life proves to be in this test. The best phone for overall battery life, however, is the OnePlus 13, which continues the OnePlus trend of offering outstanding battery life and super-fast charging. This is the biggest and best battery in a OnePlus phone to date, and shows that Silicon Carbon is the smartphone battery future we've been waiting for.
