You’d Never Lick a Toilet Seat… But You Might Be Doing Worse With Your Phone
Carrying your phone everywhere means it picks up bacteria from every surface.
Your phone might be the dirtiest thing you touch all day. From sweaty workouts to bathroom breaks and everything in between, smartphones pick up germs fast…and hang onto them. Studies have found that the average phone is often filthier than a toilet seat, harboring bacteria you definitely don’t want on your hands or face.
If you’re not disinfecting regularly, you’re probably spreading that grime without realizing it. The good news? You don’t need expensive gear to fix it. With a simple cloth and safe cleaning solution, you can wipe away the bacteria without harming your screen. Here’s how to clean your phone the right way and keep your device (and hands) a little less gross.
The Federal Communications Commission suggests disinfecting your phone daily, but not all cleaning methods are safe. Harsh chemicals and abrasive materials can damage protective coatings and potentially harm your screen. To keep your phone both clean and intact, it’s crucial to use the right cleaning techniques.
We’ll guide you through the best methods and products for keeping your device germ-free, from iPhones to Samsungs, and whatever their level of water resistance may be.

What are the best products for daily cleaning?
After touching surfaces that see a lot of action from the public — such as door handles, seats on public transportation, grocery carts and gas pumps — you might think you need a heavy-duty cleaning agent to use on your phone. However, you should avoid rubbing alcohol or products made of straight alcohol, since they can damage the protective coatings that prevent oil and water from harming your screen.
Some suggest making your own alcohol-water mix, but getting the concentration wrong can damage your phone. The safest option is using disinfectant wipes with 70% isopropyl alcohol. For daily cleaning, consider a UV light product like PhoneSoap, which kills 99.99% of germs and bacteria. We can also turn to phone manufacturers and cell service companies for guidance, too.
Apple now approves using Clorox Wipes and similar disinfectants, which was not recommended before the pandemic since they were thought to be too abrasive on the screen’s coating. AT&T advises spraying a 70% isopropyl alcohol solution on a soft, lint-free cloth and wiping your device down. Samsung also recommends using a 70% alcohol solution with a microfiber cloth. Always make sure your phone is powered off before cleaning it.
What are the best methods for removing fingerprints, sand and makeup?
Sometimes your phone needs a more specific treatment when washing up. The recommended process for daily cleaning may not be enough to remove pesky grains of sand after a beach vacation or tough foundation stains.
Get rid of fingerprints
Fingerprint smudges are inevitable since your skin produces oils. Every time you pick up your phone, your screen will get fingerprints. The safest way to make your screen print-free is with a microfiber cloth. For a deeper clean, dampen the cloth with distilled water (never apply water directly to the screen) and wipe down the surface. This works for the back and sides of your phone as well.
Alternatively, try a microfiber screen cleaner sticker that sticks to the back of your phone for easy wiping.
Remove sand and small particles
Grains of sand and lint can easily get stuck in your phone’s ports and crevices. To remove it, we recommend you use Scotch tape. Press it along the creases and speaker, then roll it up and gently insert it into the ports. The tape will pull out any debris. You can then just simply throw away the tape for easy cleanup.
For smaller speaker holes, use a toothpick gently or a small vacuum crevice tool to suck out the debris. These tools work well for other small appliances or hard-to-reach areas in your car too.
Cleanse makeup off your phone screen
When you wear makeup and skin care products, such as foundation and moisturizers, you’ll leave residue on your phone screen. While makeup remover works for your face, it’s not safe for screens due to potentially harmful chemicals. Instead, try a screen-safe makeup remover like Whoosh, which is alcohol-free and gentle on all screens.
Alternatively, use a damp microfiber cloth to clean your phone, then wash the cloth afterward. Make sure your cloth is only slightly wet to avoid soaking your phone in water.
What if my phone is waterproof?
For waterproof phones (IP67 and above), it’s best to clean the device with a damp cloth instead of submerging or running it under water — even if the phone advertises that it can withstand submersion for a certain amount of time.
Afterward, dry your phone with a soft cloth, ensuring all ports and speakers are patted dry. While your phone can withstand water, submerging it can lead to water in the ports, delaying charging. Remember, water resistance is meant for accidents, not swimming or regular cleaning.
Things to avoid when cleaning your phone
We’ve already covered why you should avoid makeup remover and rubbing alcohol, but those aren’t a comprehensive list of harmful cleaning agents. Here are a few other items and products you should never use to clean your phone:
- Hand sanitizer: Fragrances and ethyl alcohol found in many sanitizers can harm your phone.
- Window or kitchen cleaners: Harsh cleaners can strip the protective coating on your phone and leave it more vulnerable to scratches.
- Paper towels: Paper can shred, making the debris on your phone much worse, and the rough texture can leave scratches on your screen.
- Dish and hand soap: Most soaps require you to combine them with water, and since you should keep water away from your phone, it’s best to stick to a damp cloth.
- Vinegar: Like cleaners and alcohols, vinegar will strip your phone screen’s coating.
- Compressed air: Blowing intense and direct air into your phone’s portals can cause damage, especially to your mic. Apple specifically warns iPhone owners not to use compressed air.

Which Apple Watch Is for You? Apple Watch Series 11 vs. Ultra 3 and SE 3
Apple revamped its entire Apple Watch line, but some models got more improvements than other. We look at all the details.
When you’re looking to buy a smartwatch, whether you want a way to stay on top of notifications or its health-related features, the Apple Watch is a good place to start. But there isn’t just one. Apple sells three different versions that appeal to different needs.
The flagship Apple Watch Series 11, rugged Apple Watch Ultra 3 and economical Apple Watch SE 3 models are a lot closer in features and specs than they’ve ever been. Let’s compare them to see which deserves a place on your wrist.
Pricing the Apple Watch Series 11, Ultra 3 and SE 3
The current Apple Watch line spans a wide price range, from $249 for the Apple Watch SE 3 to $1,299 for a titanium Apple Watch Series 11 with an Hermès band. Like most fashion accessories, you can choose from different case sizes, materials, cellular connectivity options and bands to find the right fit — and price — for your watch.
The Apple Watch Series 11 offers the widest price range, with two case sizes, two body materials, optional cellular connectivity and premium Hermès models. The Apple Watch SE 3 is available only in aluminum and has the earlier, slightly smaller case sizes. The Apple Watch Ultra 3 comes only in titanium, with a single 49mm size and cellular included by default.

Here’s how they break down:
| Apple Watch Series 11 | GPS | GPS plus cellular |
|---|---|---|
| 42mm aluminum | $399 | $499 |
| 46mm aluminum | $429 | $529 |
| 42mm titanium | $699 | |
| 46mm titanium | $749 | |
| Hermès 42mm titanium | $1,249 | |
| Hermès 46mm titanium | $1,299 | |
| Apple Watch SE 3 | ||
| 42mm aluminum | $249 | $299 |
| 46mm aluminum | $279 | $329 |
| Apple Watch Ultra 3 | ||
| 49mm titanium | $799 | |
| Hermès 49mm titanium | $1,399 |
Series 11 vs. Ultra 3, SE 3 physical designs
The core rounded-rectangle design of the Apple Watch has seen incremental changes since its first iterations. The Series 11 shares the slimmer 9.7mm height profile of the Series 10, with 42mm and 46mm diagonal sizes. Weight is light across the board, from 29.7 to 43.1 grams depending on size and case material. Aluminum models come in space gray, jet black, rose gold or silver, while titanium versions are offered in natural, slate or gold finishes.
The Apple Watch SE 3 is slightly thicker (10.7mm) and slightly smaller, with 40mm and 44mm sizes. Its design most closely harkens back to earlier Apple Watch models. It weighs 26.4 grams or 33 grams, depending on the case size. As the no-frills option, the SE 3 is available in either midnight (black) or starlight (silver).
The Ultra 3 is the most significant departure from the original design, with a thickness of 14.4mm, a 49mm diagonal, and a weight of 61.6 grams. Its titanium body comes in either natural or black — unless you opt for the Hermès edition, which is only offered in natural.
CNET lead writer Vanessa Hand Orellana described the Ultra 3 in her review as being «like the luxury Land Rover you see in safari brochures: It’s adventure-ready on the outside, with all the modern conveniences on the inside.» The body is also 3D-printed from 100% recycled titanium, but you’d never know it; there are no telltale layering marks found on most 3D-printed items.
Each watch has Apple’s Digital Crown and a side button. The Ultra 3 also includes a programmable Action button, which can, for example, start a workout with a single press.
Aside from looks, all three Apple Watch models are built for durability. The SE 3 is water resistant to 50 meters, so you don’t need to baby it — whether you’re showering, swimming or just living through a rainy Pacific Northwest day.
The Series 11 is also rated for water resistance to 50 meters, while the Ultra 3 doubles that to 100 meters. They’re also both certified IP6X dust-resistant, which is better than the SE.
Series 11 vs. Ultra 3, SE 3 displays
The Series 11 and Ultra 3 both use an LPTO 3 OLED display, which offers an always-on display and a wide viewing angle, so you don’t need to look at it head-on to see the time. It can also get very bright: 2,000 nits of peak brightness for the Series 11 and 3,000 nits (the same as the iPhone 17 Pro) for the Ultra 3.
The energy-efficient screen can refresh its display at just one nit of brightness once every second when in its passive state, so you can always see the second hand or indicator (depending on the watch face).
The display is protected by a sapphire crystal on the titanium Series 11 and the Ultra 3. According to Apple, the aluminum Series 11 uses Ion-X glass, which is twice as scratch-resistant as the Series 10.
In past generations, the SE was stuck with the lowest-quality screen, but not this time. The SE 3 gets an always-on LTPO OLED display that reaches up to 2,000 nits of brightness and dims to just 2 nits when inactive. But it doesn’t refresh as often as the Series 11 and Ultra 3, so the seconds indicator only appears when the screen is active. It’s still a big «quality of life» bump from prior SE watches, which don’t have an always-on display mode.
Series 11 vs. Ultra 3, SE 3 battery life
One surprise with the new Apple Watch lineup is improved battery life in the Series 11 and Ultra 3, plus a fast-charge option on the SE 3 that lets you top up for a night’s sleep after a full day.
Apple claims up to 24 hours of use on a single charge for the Series 11, up from 18 hours for the Series 10. It also claims up to 38 hours in Low Power mode, a notch above the Series 10’s 36 hours. That fast-charging option can bring the battery level up to 80% in 30 minutes, but charging the watch for just 15 minutes can boost it for up to 8 hours.
Hand Orellana writes in her Series 11 review, «The six-hour battery bump on the Series 11 may not sound like much on paper, but it’s given me some welcome breathing room to figure out a better charging strategy.»
The SE 3 still delivers up to 18 hours of use, or 32 hours in Low Power mode. It also supports fast charging — up to 80% in 45 minutes, or about eight hours of use from a quick 15-minute top-up.
If you want the most time between charges, the Ultra 3 is the Apple Watch to get. It can last for up to 42 hours, per Apple, or up to 72 hours in Low Power mode. Fast charging its larger battery takes it to 80% in about 45 minutes, and 15 minutes on the cable will give you roughly 12 hours of power.
Some of these gains come from Apple factoring in a night’s sleep, but credit also goes to the more power-efficient LTPO 3 screen in the Series 11 and Ultra 3.
It’s one thing to reference Apple’s claims, but what about battery life in practice? In Hand Orellana’s review of each model, she recorded even better battery life than Apple’s estimates. Keep in mind your daily usage will affect results, but here’s what she found:
| Apple Watch | Apple’s estimate | CNET review |
|---|---|---|
| Series 11 | 24 hours | 27-32 hours |
| Ultra 3 | 42 hours | 45-49 hours |
| SE 3 | 18 hours | 20-25 hours |
Series 11 vs. Ultra 3, SE 3 health features
The Apple Watch SE line has always sacrificed some hardware and features to remain the least expensive option, and the SE 3 continues that tradition — but not to the same extent. It lacks an electrical heart sensor found in the Series 11 and Ultra 3, so it can’t take heart readings using the ECG app to look for signs of atrial fibrillation (Afib).
According to Apple, the SE 3 uses a second-generation optical heart sensor that tracks heart rate during exercise, sleep and potential emergencies — though, like all Apple Watches, it can’t detect heart attacks or measure blood oxygen. The Series 11 and Ultra 3 upgrade to third-generation optical heart sensors.
The SE 3 is also missing a water temperature sensor and depth gauge, making the Series 11 and Ultra 3 better options if you spend a lot of time in water and want to track swim workouts or shallow dives more reliably.
This year’s standout health feature is the ability to analyze data and detect signs of hypertension, or high blood pressure. «It’s not the full on-the-spot blood pressure monitoring Apple fans have long hoped for,» wrote Hand Orellana, «but it’s a major step forward — one that Apple says could help 1 million people get diagnosed with hypertension in the first year alone.»
Like the sleep-apnea tracking introduced last year, hypertension notifications are not a screening tool; think of it as a warning system that prompts you to get checked out by your doctor. The Series 11 and Ultra 3 include this ability (sorry, SE 3), and require 30 days of data collection before triggering notifications. The Series 9, Series 10 and Ultra 2 also get hypertension notifications in WatchOS 26.
Series 11 vs. Ultra 3, SE 3 connectivity
Each Apple Watch model supports cellular connectivity, so you can stay connected even when your iPhone is at home. You can order the aluminum Series 11 models and the SE 3 with the cellular option; the titanium Series 11 and the Ultra 3 include it by default.
What’s unique about these watches is their support for both 5G and LTE networks, offering faster speeds and broader compatibility. Plus, they use 5G Reduced Capacity technology, which is more power efficient than the 5G networking in your iPhone.
They also support Wi-Fi 4 (802.11n) at 2.4 GHz and 5 GHz, Bluetooth 5.3, and L1 GPS location chips. The Ultra 3 includes dual GPS radios (L1 and L5) for more precise location tracking, especially in challenging environments like dense downtown corridors.
Plus, the Ultra 3 offers satellite connectivity directly from the watch. With a direct view of the sky, it can communicate with overhead satellites to send and receive texts, share your location, and access emergency services.
Series 11 vs. Ultra 3, SE 3 processors
One of the biggest surprises in the lineup? The Apple Watch Series 11, Ultra 3 and SE 3 all include the same S10 chip. It’s worth noting that the S10, introduced in last year’s Series 10, isn’t a new processor generation for 2025. But each watch now includes 64 gigabytes of storage, a four-core Neural Engine and a 64-bit dual-core processor.
The only significant difference is that the Apple Watch SE 3 is the only model not to feature Apple’s second-generation Ultra Wideband chip, which enables precise location tracking. You can still use Find My on an iPhone (with UWB) to see if the SE 3 is with you or if you left it at home. But with the Series 11 and Ultra 3, Find My will point you in the right direction as you get closer to your mislaid watch.
WatchOS 26 on the Series 11, Ultra 3 and SE 3
Each model is preloaded with WatchOS 26, which has the new Liquid Glass interface (though in most cases, it’s quite subtle). And all models add features like the new Wrist Flick gesture, nightly sleep scores, Workout Buddy, the Notes app and live translation in Messages. The Series 11 and Ultra 3, with their upgraded sensors, also gain hypertension notifications.

NASA Admits Fault in Starliner Test Flight, Classifies It as ‘Type A’ Mishap
Remember the astronauts who were stranded in space for months? NASA says it’s close to identifying the «true technical root cause» of the spaceship malfunctions.
NASA has been investigating the now-infamous Boeing Starliner incident since the story dominated headlines in late 2024 and early 2025. The Starliner suffered malfunctions that stranded now-retired astronauts Suni Williams and Butch Wilmore for months. The agency has now released a report on what happened, taking responsibility for its role in the mission’s failure.
«The Boeing Starliner spacecraft has faced challenges throughout its uncrewed and most recent crewed missions,» said NASA Administrator Jared Isaacman in a NASA blog post on Thursday. «While Boeing built Starliner, NASA accepted it and launched two astronauts into space. The technical difficulties encountered during docking with the International Space Station were very apparent.»
NASA has now labelled the mission a «Type A mishap,» which is defined as a «total direct cost of mission failure and property damage greater than $2 million or more,» or where «crewed aircraft hull loss has occurred.» Both of those apply to the Starliner, which has cost the agency $4.2 billion to date.
Isaacman also released a letter addressed to all NASA employees on X. The letter outlined various issues with the mission, including a «prior OFT thruster risk that was never fully understood,» disagreements among leadership about Williams and Wilmore’s return options, and the agency’s delay in declaring the mission a failure, despite its high-profile nature clearly showing it was.
These sentiments were echoed in NASA’s press conference on Thursday.
NASA has committed to working with Boeing to make the Starliner launch-worthy again and has been investigating technical issues and addressing them since the mishap early last year. Isaacman admitted at the press conference that the «true technical root cause» of the malfunctions still hasn’t been identified, but NASA believes it is close to identifying it.
«We’re not starting from zero here,» Isaacman told a reporter during the press conference. «We’re sharing the results of multiple investigations that will be coming to light in the hours and days ahead. Boeing and NASA have been working to try and understand these technical challenges during that entire time period.»
A malfunction to remember
The crewed Starliner flight was delayed several times before finally launching on June 5, 2024. The crew experienced malfunctions en route to the ISS, including several thruster failures, which made docking particularly stressful.
The Starliner’s return was delayed by two weeks before finally being sent home without Wilmore and Williams, who were left stranded on the ISS until returning with Crew-9 in March 2025.
The Starliner’s story is far from over. NASA and Boeing intend to send the Starliner back to the ISS in an uncrewed resupply mission with a launch date currently set for April 2026.
