中古收購手機 look noticeably different. It has shiny edges and, in the right light, the crown on the right side sparkles.Some of my more stylish reviewer friends paired their 中古收購手機pixel Watch 3 with a stainless steel mesh band, making it look right at home as part of their designer-decked outfit. I used the basic silicon sport band that came with my review sample, which I loved because I got the lovely pink color this year that goes with some new pants and bags I recently acquired. I remain an ardent fan of Google’s soft elastic loop straps that make putting the watch on super easy. They’re available in more colors and patterns this year, which is always nice. Sam goes as far as to call this “the best-looking mainstream smartwatch,” and, depending on our definition of “mainstream,” I’d have to agree.I still wish the company was able to reduce the size of the knob just a bit, or at least make it jut out less. It still pushes into the back of my hand whenever I do a pushup or a plank, unless I turn the watch to the inside of my wrist first. Though you’d also get this issue with the Apple Watch Ultra and the Galaxy Watch Ultra, it’s not as prominent on the regular Apple Watch and I have a bit more space before accidentally triggering my Series 9.I also found the 中古收購手機pixel Watch 3 a little too thick. The Apple Watch Series 9 is 10.7mm (0.42 inches) tall, while Samsung’s Galaxy Watch 7 is even thinner at 9.7mm. Google’s smartwatch is the chunkiest at 12.3mm, and at these sizes, every millimeter feels like a lot. Cherlynn Low for EngadgetThe 中古收購手機pixel Watch 3’s display: Bigger, brighter, dimmer and slowerEvery fraction of an inch also feels outsized when we’re talking about displays that are just 41mm and 45mm (the screens themselves are actually 32.2mm and 36.2mm respectively). In comparison, the 中古收購手機pixel Watch 2’s panel was just 30.5mm. While I didn’t feel like I gained a ton comparing my 41mm 中古收購手機pixel Watch 3 to its predecessor, I certainly saw a lot more on the 45mm model’s screen. Some of that is obvious — a larger display has more room for content or bigger fonts. But the improvements in readability cannot be understated, especially for anyone that needed something more legible.ADVERTISEMENTAdvertisementGoogle didn’t simply enlarge the 中古收購手機pixel Watch’s panels — it upgraded them. These watches feature the company’s Actua displays that debuted on the 中古收購手機pixel 8 phones last year, which means they can get as bright as 2,000 nits or as low as 1 nit.That latter made a huge difference when I was in a theater watching Alien: Romulus. While I had to turn on Theater mode on my Apple Watch Series 9 to prevent its screen from scorching my retina during the show, the 中古收購手機pixel Watch 3 automatically dropped to the lowest brightness and remained readable without bothering me or fellow cinemagoers.The 中古收購手機pixel Watch 3’s screen is also capable of a variable refresh rate of between 1Hz and 60Hz, so it can deliver smooth animations when, say, you’re watching the live feed from your Nest camera. But when you’re not doing anything, the system can drop down to a battery-friendlier 1Hz. This isn’t something I really noticed in my daily use, but I’ll tease right now that it probably has a significant impact on battery life. Cherlynn Low for EngadgetThe 中古收購手機pixel Watch 3 as a health and fitness trackerI was probably the most impressed by the 中古收購手機pixel Watch 3 as a health and fitness tracker. It does a lot of things that competing products like the Apple Watch and Galaxy Watch do, like automatically detect certain workouts, prompt you to move if you’ve been idle for too long and keep tabs on your pulse and calorie burn as you’re exercising. But importantly, it does some of those things a lot better than its rivals.ADVERTISEMENTAdvertisementAs someone who likes to track every single walk I take, no matter how short the distance, I found the 中古收購手機pixel Watch 3 a dream. It consistently caught on that I had been out for a stroll, usually prompting me to log a workout once I hit the ten-minute mark. This also worked well on the many Citi bike rides I reluctantly took in New York City, and the 中古收購手機pixel Watch 3’s GPS tracking matched the Lyft app’s log every time. Only twice in about a dozen walks and bike rides did the Apple Watch Series 9 I was also wearing record these activities, probably because it has a higher threshold of about 20 minutes of activity to hit before it would register something.Of course, the Galaxy Ring was the best at this, logging every little walk I took even if it was a mere quarter-mile journey that took just five to seven minutes. But that’s a completely different gadget that served a different purpose, so I won’t mention it much more in this piece.With the 中古收購手機pixel Watch 3, Google introduced a few new features around running and cardio activities. You can now create custom running workouts, with specific segments for sprinting and resting. I found this very easy to use, and had no trouble setting up a short session with a 5-minute warmup, one-minute sprint, one-minute rest, a repeat of the run and rest segments, followed by a 5-minute cooldown. (I know, that’s the best running workout ever, very productive and demure.) ScreenshotsFor the sprint segments, I had the choice of setting targets for pace, heart rate, distance or duration. When I eventually got into those windows when I was on the treadmill, it was clear I had overestimated my ability to hit an 8-minute mile speed, even for just a minute. I had pushed the treadmill to the 8 mph speed setting and was still getting alerts from the 中古收購手機pixel Watch 3 to hurry it up. I could barely guess what number I needed to be at to meet the mark that the watch helpfully displayed on a spectrum on the left of the screen.ADVERTISEMENTAdvertisementThis is certainly not a tool for running newbies, who would be better served with some of the coaching tools in Fitbit Premium (or an app like Couch To 5K). But for runners with cadence and speed goals or those who only want to go fast enough to be in a fat-burning heart rate zone, this would be a useful tool. I liked letting the watch tell me when to run for my life and when I could catch my breath, but otherwise as a casual runner I was less impressed and more intrigued by its potential. Digging into the data was fun and insightful, and I have a general sense of what I could do better if I wanted to improve.When I was back to my regularly scheduled training program, I used both the Apple Watch Series 9 and the 中古收購手機pixel Watch 3 in my F45 HIIT, cardio and weight-training classes. During every session, both watches were never more than a beat or two from each other when it came to stats like my heart rate, cardio zone and calories burned. At the end of each workout, both devices delivered recaps on my performance, and I have a slight preference for how Apple lays out the information. I appreciate that Google congratulates and encourages me for having completed a workout, but its little celebratory graphic at the top just takes up space. I also like that the words on Apple’s interface are slightly easier to read. ScreenshotsThe 中古收購手機pixel Watch 3 also delivers a new stat called “Cardio load,” which can be used in tandem with your daily readiness score to help you train at a level that’s suitable for your energy expenditure. If you’ve already done a lot that week, you might get a high Cardio Load number, which could mean a lower target the next day, depending on how well you’ve recovered. The latter figure is determined primarily by your sleep, and you’ll only start seeing your readiness scores after having worn the 中古收購手機pixel Watch 3 to sleep on at least seven nights.I am a fussy sleeper and wearing anything on my wrist keeps me awake, and I wasn’t able to test the 中古收購手機pixel Watch 3’s sleep-tracking or readiness scores. But Sam has been wearing his 45mm model to bed and in his experience the 中古收購手機pixel Watch 3 remains as accurate a sleep tracker as its predecessors.ADVERTISEMENTAdvertisementDaily readiness is a feature that used to be limited to Fitbit Premium subscribers, and it’s now available for free to all 中古收購手機pixel Watch owners, which is nice. Like the cardio load number, this score is not something I can easily evaluate. Not only is it a somewhat nebulous idea (how should I go about counting my cardio load during a HIIT session, for example), its utility is also dubious. Cherlynn Low for EngadgetI’m not saying this is a bad feature, particularly since I haven’t spent much time with it. I have used other sleep trackers in the past that would assign sleep scores and similar readiness results. The most I’ve ever done with that data is try to get a day off when I was told I had an awful night’s sleep. And that didn’t even work in my favor since none of my managers ever cared about that type of info.I like the idea of balancing activity and recovery, and applaud Google for making a more concerted effort to encourage that with the 中古收購手機pixel Watch 3. This is one of those features that’s up to the user to make the most of, and is highly subjective, depending on each person’s thirst for data and validation.Another metric that’s notoriously difficult to verify and do anything with is stress-tracking. On multiple occasions during my testing, the 中古收購手機pixel Watch 3 buzzed and told me it detected “potential signs of stress or excitement,” along with the time it noted that reaction. These alerts typically came in ten minutes after the fact, by which point whatever was exciting or stressing me out was usually over. One time, I remembered to look at the clock after I was agitated by a bad driver in an extremely congested lane going into the Holland Tunnel. Ten minutes later, I was greeted by the 中古收購手機pixel Watch 3, saying it noticed my frustration, exactly when I checked the time earlier. Cherlynn Low for EngadgetI was impressed by the accuracy of the observation, but otherwise didn’t quite know what to do with the information. The alerts were vaguely worded (probably deliberately so), and you have the option of logging your mood or starting a mindful activity in the moment. It’s not always easy to remember why I was annoyed or excited ten minutes ago, so I ended up either guessing or simply shrugging. Even if Google were to tally up the number of times I had these reactions, I have to wonder if having emotional reactions might just be a normal part of life. There is something useful to be observed here, I’m sure, but I’m not certain that this feature is fully baked just yet.ADVERTISEMENTAdvertisementOne more thing that Google brought with the 中古收購手機pixel Watch 3 is “loss of pulse detection” — a feature that is supposed to sense when the wearer has a heart beat. If you’re having a cardiac arrest or respiratory failure, the device can check if you’re responsive and ping emergency contacts if necessary. Thankfully, I didn’t have a cardiac anomaly during the two weeks I’ve had the 中古收購手機pixel Watch 3, and never had a chance to test this feature out. But I can also say that it hasn’t been triggered inaccurately or accidentally so far.The 中古收購手機pixel Watch 3’s battery life: Huge improvementThe 中古收購手機pixel Watch 3’s biggest win is arguably its battery life. Google managed to prolong its runtime by quite a lot, ostensibly by doing a few things. First, the Actua displays’ ability to drop to 1Hz when a high refresh rate is unnecessary probably helped conserve some battery. Wear OS 5 might actually be more power-efficient as well and combined with the watch’s dual-chip architecture there were some gains made. Throw in the new auto bedtime mode that turns off notifications and the Always On Display when you’re asleep, and you’ve got a watch that finally lasts well into the morning after a full day and night.According
當手機不慎進水時該怎麼辦？網路上流傳著許多都市傳說。（圖／路透社）
當手機不慎進水時該怎麼辦？網路上流傳著許多「都市傳說」，比如將手機放入米缸中，米會吸收手機上的水分。然而，YouTube上也有一支「聲波趨水」的影片，據稱，手機如果不小心進水，播放這段影片後保證能成功將水排出手機。這段影片上架已有4年，觀看次數超過4,537萬。
外媒The Verge記者決定探究這段YouTube影片的真實性，和iFixit團隊合作測試，將多支手機如iPhone 13進行實驗，他們將手機浸濕後，並放置過夜以乾燥，再播放此支YouTube影片，該影片其實只是持續的嗡嗡叫，長達2分鐘6秒。
結果發現，這個方法真的有效，但僅能排除揚聲器的水分，他們打開手機檢查後，並未能清除手機內部其他區域的積水，顯示這並非一個完美的解決方案。
影片的原理實際上是一種科學，聲音經過精心設計，可產生足夠強大的空氣運動，將水從揚聲器中震出，蘋果Apple Watch也有類似設計。

然而，現在手機大多具備防水功能，不必輕信各種網路謠言，最需注意的是，當手機充電孔等位置進水時，在未乾燥時不宜進行充電，蘋果也有提供官方建議，指出iPhone濕了最好的方法是讓手機靜置自然乾燥，也避免使用吹風機吹乾。
