Samsung's Galaxy ‘Kill Switch' Completely Changes Your Phone
This is a game changer
Samsung is moving quickly to recover ground lost through its One UI 7 delays. The Galaxy-maker has now confirmed that early access to the One UI 8 beta is now available, 'kicking off a new era of software intelligence.' What happens next is critical. How far will Samsung fall behind Pixel's unbeatable June release?
But the advantage Samsung has this time is the relatively modest scale of One UI 8 versus the wholesale One UI 7 update that still has not completed its rollout. But literally hidden in amongst the various tweaks we know are coming is a brilliant update that could be a game-changer. 'Think of it as a kill switch for your private digital life.'
That's how Android Police describes the new 'Hide Secure Folder' button that instantly disappears the folder's icon and apps. 'When hidden, 'apps and data stored in Secure Folder are encrypted.' All apps within the folder will stop working and you will not receive any notifications from them until you unhide and decrypt the Secure Folder.'
This I really like. It is an OS-level deployment of the kind of personal security and privacy that's much needed when kids and others might browse through your phone, playing games or watching media or looking at photos. It also stops awkward notifications appearing when your phone might be on view to others.
Android Authority has done its usual deep dive on the new upgrade, and says 'Secure Folder on One UI 8 is easier to use and safer than ever.' This is especially welcome given the security vulnerabilities highlighted with Secure Folder in recent months, and that Samsung has chosen to go a different way to Android's generic Private Space.
Galaxy's new 'kill switch'
The other headline upgrade is forcing users to re-enrol their biometric security for Secure Folder, separating it into its own enclave. This means if you've enrolled someone else's fingerprint for generic phone access — one of your kids or your partner, that does not mean they will have access to the personal Secure Folder which is hived off.
'While your lock screen already helps keep the data on your phone safe from casual access,' Android Authority says, this 'offers an extra layer of security, particularly handy if you know that other people are going to be using your device. You can move your most private data to its encrypted protection, and even hide its presence entirely.'
That kill switch will grab the headlines though, 'a new Quick Settings button not just hides the Secure Folder without forcing you to did through settings menus, but also shuts down the apps you've moved there and silences their notifications. Considering this is where Samsung encourages us to keep our most sensitive stuff, a super-quick way to just sweep it all under the rug feels like a completely on-brand addition.'
This should completely change how you use your phone and think about carving out data and apps that are for you and you alone. Once live, if this is a seamless and polished as promised, it's something other phones — including iPhone — should copy.

The best portable chargers of 2025, tried and tested
The best portable chargers we tested Best budget portable charger: Iniu Pawsible P41L-E2 Power Bank Best portable charger for phones: Anker Nano Power Bank Best portable charger for laptops and tablets: UGreen 145W Power Bank Testing the best portable chargers might sound boring, but I love to figure out which power brick is worth your cash. This is partially because the world of portable chargers is increasingly confusing, filled with vaguely-named products sold by companies you may have never heard of. On top of that, this is the kind of small purchase that can add years of life to your other devices, which is crucial when even the best smartphones released every year don't always have compelling reasons to upgrade. Portable chargers have become far more interesting in recent times, going beyond their ports to add built-in cables and screens so you can forget your cords at home and stop guesstimating at how much of your charge is left. That said, I'm still happy to see that the top portable chargers offer USB-C for faster charging and USB-A ports for older cables and devices. To make sure you're never low on battery life, I put nearly a dozen of the top battery packs through a series of intensive tests, and I've got my eye on the market to see what's up next from the titans of tech recharging. All of this work has led me to the top three portable chargers, which range from affordable power banks to keep your phone in the green to a powerful brick that will keep your laptop aglow when you can't find an open wall adapter at the airport. Iniu Pawsible P41L-E2 Power Bank This power bank may have an awkward name, but it more than makes up for that with fast charging speeds and its built-in cable. Anker Nano Power Bank This is the charger I never go out without, and with good reason. It offers both fast charging and a convenient design that means I can scroll and swipe while I'm refueling my phone. Read our review UGreen 145W 25000mAh Power Bank While it's a bit larger than most, this simple and straightforward power brick is an excellent option for those looking to keep all of their tech — from laptops to watches — charged during intensive days on the go. Lesser-known tech accessory brand Iniu makes its name by offering the best affordable portable chargers. The Pawsible P41L-E2 is simply a better version of our previous budget pick, offering a built-in cord and faster charging for only a little more. Its best scores on our in-house testing came when I recharged an Apple iPhone 16 and Samsung Galaxy S25 Ultra from dead, checking how much charge was refueled after 30 minutes. The Iniu Pawsible P41L-E2 was the only portable charger below $40 to refill over 50% of the iPhone 16's charge in 30 minutes, and its 70% score on the S25 Ultra even beat a portable charger that costs $100. It also beat our previous budget pick, the simply named Iniu Portable Charger (which is often on sale for less than $20) by posting charging scores between two to three times higher than its cheaper sibling. In addition to that performance, this portable charger comes with its own built-in USB-C cord, which isn't included on far-more expensive competitors. That means you won't have to remember to pack a cable (provided you're on a modern Android phone or the iPhone 15 or later) for your next night out. While this portable charger did a serviceable job bringing an iPad Pro M4 back from zero battery life, I saw a surprising hiccup when it could not bring the Samsung Galaxy S10 FE+ back from an empty charge. I will continue to investigate this issue, and plan to update this article with my findings. Oh, and those looking for precision might not like its 'paw' LEDs, which give you an estimate of remaining battery life with up to five lights illuminated. Neither of those are a concern at this price, though. Not only did the Iniu power bank thrive in phone recharging, it did so for the same price as a month of 4K Netflix. Our best overall portable charger basically takes nearly everything I like about our budget pick and puts it in a better package. The 30W Anker Nano Power Bank posted a terrific score in the iPhone charging test, tying with the Iniu Pawsible P41L-E2. Also, the Nano's built-in USB-C cord is just better than the one in the Iniu charger, or at least it's designed to be easier to work with. That's all due to the most ingenious touch, a little metal hook that turns the Nano's cord into a loop that makes it easy to hold while you use the phone. You just snake the connector side of the USB-C cable out from the top side, plug it into your phone, and then hold the power bank aloft by tucking your pinky and/or ring finger into the resultant loop. This way, the Anker Nano isn't pulling itself down from your port, and you can use your phone while you recharge it. This is crucial for anyone who loves to travel, as you can easily charge and use your phone in one hand to figure out where to go in a maps app while drinking a coffee or holding an umbrella with your spare hand. The Anker Nano also features a screen that will tell you the exact percentage of remaining battery life and how long it will take to recharge when you're refueling it. The only real downside about this portable charger is that its 30W charging speed isn't the fastest you'll get at this price point. For example, the cheaper Iniu Pawsible P41L-E2 refilled 70% of the S25 Ultra's battery in 30 minutes, blazing past the 45% score from the Anker Nano. If you're trying to decide between the Anker Nano and the Iniu Pawsible, find out if your phone supports 45W charging or not. If it does, and you really want the fastest pocket-friendly portable charger out there, get the Iniu. I'm betting that most people don't have a 45W-charging phone, and are willing to settle for 'really fast' when they can get the portable charger that's the easiest to use. And that's why I think the Anker Nano is the best for most people. Sometimes simple gets the job done best, as is the case with UGreen's big brick for charging everything you can throw at it. Not only did it recharge the iPhone 16 and Galaxy S25 Ultra about as fast as any other portable charger (basically tied in the margin of error), but its 145W power meant it posted phenomenal charging scores when I refueled the MacBook Air M4 and Lenovo Yoga Slim 7x. And I'm not exactly shocked: you should be seeing superior charging time when you're spending more than $70. Just like the Anker Nano, this UGreen power bank gives you a trio of output options, with dual USB-C ports and one USB-A port. A quick tap of the little button on the side turns on its LCD screen to show you how much juice is left, so you can tell if you need to recharge or not. Oh, and unless you're frequently refueling laptops, this power bank's 25000mAh capacity should serve you well for typical use. The other reason I love this brick is that it often gets discounted well below its $100 retail price; as of this writing, Amazon Prime members can get it for $75. The one thing I don't love about UGreen's laptop charger brick is that it's a bit on the simple side, only offering a low-power 'trickle' mode when it's time to charge smaller devices like wearables. If you're willing to spend more for some nice extras, then I'd recommend you look at the Anker Laptop Power Bank, which costs $35 more, but throws in two built-in USB-C cords, including a retractable cable and one built into its wrist strap. Oh, and you also get a better display for telling you about its status. Also, when it comes time to refuel UGreen's brick, you're going to want to have one of the best USB-C chargers, because refueling it from a USB-A port is going to take far more time than you should spend. Still, since power outlets can be extremely hard to come by on the go, I recommend everyone check out this UGreen power bank if they frequently find themselves struggling to keep their laptop chugging. Design Size: Phones are getting big enough these days (some tell me they're too big), so there's no need for you to be carrying a portable charger that's too huge for easy storage. So, I applaud the more compact chargers for understanding that pockets and purses only have so much space. Many of these chargers manage to fit a lot of charge into a small design thanks to their lithium-ion batteries. Capacity: Then there's the other size: each portable charger has its own mAh rating for its maximum internal electrical charge. The bigger the mAh rating, the bigger the battery inside and the more it can recharge. I only tested portable chargers with 5,000 mAh or higher capacities in this round — that's pretty much the standard entry point, since most popular smartphone batteries are near that amount. Ports and cables: While many portable chargers can refuel your phone quickly, their number of ports and cables can be important differentiators. Many chargers come with a cable you can use to plug it into a wall, but a portable charger that features its own built-in cable means you never have to remember to pack one of the best USB-C cables when you're headed on a trip. Also, some permanently-attached cables are better than others, as some can retract into the case or offer an easier way to hold the charger. And since none of these devices included a wall adapter, we gave extra points to those which included a cable. If you're curious, we've got everything you need to know about how USB-C works. Build quality: Does this portable charger feel durable, and able to survive a little damage? Do I feel confident plugging it into my own phone? Without a loud and direct 'yes' for both of those questions, a portable charger stands little chance of winning our respect. Warranty period: A long manufacturer's warranty should come with every portable charger, as companies should stand behind the batteries you plug into your phone. Most portable chargers we tested come with at least a two-year warranty. Performance Phones: Since the name of the game is keeping your phone's battery icon in the green, I tested how efficient these power banks are when it comes to refueling in a short window of time. I tracked how much battery life each gave some of the best smartphones in 30 minutes, after the phones had previously been drained of their charge. This round of testing consisted of recharging the regular iPhone 16 and the fast-charging Galaxy S25 Ultra (which supports speeds of up to 45W). I used the included or built-in cords to charge other devices, as well as each device's most-powerful port or cable. I also used a Yojock USB-C power meter to confirm the power of each port. Laptops: Since the smartphone isn't the only piece of tech I rely on, I checked to see if any of these portable chargers could recharge two of the best laptops: the 15-inch M4 MacBook Air and the Lenovo Yoga Slim 7x. Unsurprisingly, only our two largest portable chargers proved effective at all, as the rest only resulted in errors such as 'Battery is not charging,' and 'Slow charger, use a higher-watt charger.' When trying to look for the best portable charger for bigger devices, look for chargers with higher W (watts) specs, starting at around 100W. Tablets: In our final round of testing, I checked how our top four portable chargers fared at refueling two of the best tablets from zero. This testing was done with the iPad Pro M4 and the Galaxy Tab S10 FE+. Iniu Portable Charger Basic chargers get basic names, and such is the case with this Iniu power bank that features a 10,000mAh capacity, two USB-A ports and one USB-C port. Not exactly fast, it's certainly affordable. This Iniu Portable Charger used to be our budget pick, but its only-slightly more expensive sibling charged our phones more than twice as fast and has a built-in USB-C cord. I understand why many people will still want to get this portable charger due to its low price, but spending a little more here gets you much better results. Nimble Champ Portable Charger This little charger packs a decent 10,000 mAh capacity (enough for at least two large phones) and dual fast-charging USB-C ports. Oh, and it's designed for the eco-conscious among us, with a 90% post-consumer plastic housing and post-consumer scrap paper packaging. It also includes recycling materials for getting rid of your e-waste. This tiny portable charger did well in the iPhone 16 charging portion of our test, but it failed to post anything inspiring for the Samsung S25 Ultra, as its 20W charging power wasn't enough to keep up with other, faster-charging power banks. I admire this power bank for its environmentally-conscious design and packaging, but I have a hard time giving it a strong endorsement. That said, if you put the environment above all else, I say 'stay Nimble.' Anker 25,000mAh Laptop Power Bank Capable of charging laptops, tablets, phones and anything else you can plug into its USB-C and USB-A ports, this 25,000mAh power bank features dual integrated charging cables and an information-rich display. This is the portable charger to buy if money's no option, and if you don't mind a larger or heavier power bank. Not only does it offer dual built-in USB-C cables, but one is a retractable cable that basically hides in its body and the other doubles as a wrist-strap. The priciest portable charger on this list provided speedy-fast charging in every round, either tying for the win in nearly every category, and four points shy of the best iPhone 16 charging score. And that's well within the margin of error. The only real downside on this item, aside from its price, is that its 1.5-year warranty is at least six months less than what the rest include. Belkin BoostCharge Plus 10K Built-in USB-C and Lightning cables make this charger an easy call for anyone who needs to charge current and older Apple devices — especially at the same time. Its 10,000 mAh capacity means you'll have the juice to do it, too. Simply good-to-OK charging scores in our iPhone 16 and Galaxy S25 Ultra rounds combined with a versatile two-cord design make Belkin BoostCharge Plus 10K a worthy consideration. But when Lightning is on the way out and this charger is $10 more than the Anker Nano, it's hard to see this as a future-forward pick. It's also a little larger than some might want. Anker 22.5W Nano Power Bank A folding USB-C connector makes this 5,000mAh portable charger super easy to use. You just plug it into your phone, and you can charge while you scroll. The little sibling to our best pick for top charger, this Anker always feels like the junior. It's got a lower capacity, less charging power and its design isn't exactly as convenient. Sure, you can charge while you use your phone, but it'll leave you with a super-tall handset that's slightly awkward to use. Mophie Powerstation Plus 10K This portable charger packs USB-C and Lightning cables, and its 10,000 mAh capacity gives you enough juice to charge both your phone and a friend's. A bit pricey for what it offers, the Mophie Powerstation Plus' claim to fame in our testing was that it posted the best score for recharging the iPhone 16 from dead, but only by one percentage point. While it gave the Galaxy S25 Ultra 14% more juice than the similar Belkin BoostCharge Plus 10K, it's hard to argue that this difference is worth an extra $30. UGreen Nexode Power Bank This portable charger's 100W charging power combines with a 12,000mAh capacity to offer speed and endurance, and it's priced to move. Includes USB-A and USB-C ports. Good performance in our testing for charging the iPhone 16 and Galaxy S25 Ultra made this medium-sized portable charger one to consider, especially at $50. There's nothing quite wrong with it, but there's nothing super-compelling either, as it offers no built-in cables and a simple set of USB-A and USB-C ports. OtterBox 3-in-1 Mobile Charging Kit Need to charge over USB-C, Lightning and microUSB? Then this 5,000mAh portable charger might be the right one for you, as it comes with a microUSB charging cable that includes USB-C and Lightning adapters you can snap on top. Slow charging speeds and slightly-awkward adapters meant OtterBox's portable charger didn't live up to my own expectations. Also, with microUSB on the way out, its inclusion doesn't really feel relevant, unless you're using one of our older picks for the best e-reader. Can you bring a portable charger on a plane? Can you bring a portable charger on a plane? Yes, though there are some exceptions and rules you must abide by. In addition to the TSA battery rules, the TSA's What Can I Bring? site states that portable chargers must be packed in carry-on luggage, and not checked bags. Certain airlines are also announcing new rules, as Southwest Airlines recently revised its guidelines to state 'When a portable charger/power bank is used during a flight, it must be out of any baggage and remain in plain sight. Do not charge devices in the overhead bin.' How much do portable chargers weigh? How much do portable chargers weigh? There's an increasingly wide range of weights when it comes to portable chargers. The power banks I tested were as light as 3.6 ounces and as heavy as 20.9 ounces. Are portable chargers safe for your phone's battery? Are portable chargers safe for your phone's battery? In general, portable chargers are safe to use with your phone, and I'd know since I've been using and testing them for more than a decade. I'd include one small caveat, though: don't buy or use a portable charger from a brand you're unfamiliar with. Portable chargers are like any electronics I've covered in my product reviews, and I wouldn't just plug any one of them off the virtual shelf into my phone.

Galaxy Tab S11 leak suggests the Ultra is getting a major battery upgrade
Ryan Whitwam / Android Authority TL;DR The battery specifications for the Galaxy Tab S11 and S11 Ultra have leaked. The base model may come with a typical capacity of 8,400mAh. The Ultra could have an advertised capacity of 11,700 or 12,000mAh. Samsung is currently working on the next additions to the Galaxy Tab line. Not much is currently known about the Galaxy Tab S11 series, other than it's expected to launch in the second half of the year, there may not be a Pro model, and AI will be a point of focus. But we're getting some new information that now reveals the battery specifications. According to GalaxyClub, Samsung is going with two tablets again for the Galaxy Tab this year. A Pro model won't be a part of this two-pronged approach, but a base model will. The report claims that the base model will feature a battery with a rated capacity of 8,160mAh, but the advertised capacity will likely be 8,400mAh. This would mean the battery capacity for the Tab S11 is the same as the Tab S9. Meanwhile, the Galaxy Tab S11 Ultra is said to have a rated capacity of 11,374mAh, which would be 500mAh more than the Tab S10 Ultra. As for the advertised capacity, the Tab S10 Ultra's battery comes in at 11,200mAh. As such, it's expected that the Tab S11's advertised capacity could end up being around 11,700mAh, or even 12,000mAh. This is a pretty big deal considering Samsung has not upgraded the Ultra model's battery since its debut with the Tab S8 series. So this would be the first time an Ultra has received a bigger battery. It's still unclear when Samsung is planning to launch the Galaxy Tab S11 series. The company does have an Unpacked event coming up soon for its foldables. However, it's possible that these tablets could end up missing this event. Got a tip? Talk to us!

E.l.f. Beauty will raise prices by $1. Hear the company's CEO explain why
E.l.f. Beauty CEO Tarang Amin speaks to CNN about why the company is increasing prices by $1 across its entire portfolio on August 1. On Wednesday, the cosmetic company announced it bought Hailey Bieber's beauty brand, rhode, for $1 billion. Amid President Donald Trump's chaotic trade war with China, e.l.f. hopes the acquisition is an opportunity to diversify its supply chain. Right now, about 75% of e.l.f. products are made in China, while rhode has suppliers in Europe, the U.S. and other parts of Asia.
