1 Month Later, the iPhone 15 Is Still an Excellent Upgrade

The iPhone 15’s long battery life and excellent camera make it a top choice for people coming from an older phone.

The iPhone 15 initially won me over with its sleek matte design; convenient USB-C charging; easier multitasking thanks to the Dynamic Island; and much improved camera. Even though some of the iPhone 15’s standout features debuted last year on the iPhone 14 Pro, they still felt fresh and new to someone like me, who was coming from an iPhone 12.

One month later, those opinions still hold true. The iPhone 15 had a somewhat rocky launch, after a wave of news reports and social media posts suggested that some iPhone 15 Pro models were overheating. But I experienced only one instance in which my iPhone 15 felt noticeably warm, leading me to believe this wasn’t a consistent problem. Apple also released a software update to address the issue, so my overall opinion of the phone remains unchanged.

Now that I’ve had more time with the iPhone 15, I’ve also gotten a better understanding of its battery life, charging speeds and overall performance. I also had the chance to try out the new Precision Finding feature for pinpointing a friend’s location, which works only with other iPhone 15 models. 

A closer look at battery life and charging

I’ve been using the standard 6.1-inch iPhone 15 for almost a month, and it’s more than capable of getting through a full day on a single charge. I rarely find myself reaching for a charger during the workday, and I’ve never worried that I wouldn’t be able to make it to an after-work event like happy hour with co-workers. 

I recently attended a close friend’s wedding, and it was probably the busiest day I’ve had since switching to the iPhone 15. My day started with hair and makeup at around 9:30 a.m. and ended the following morning, once the after-party wrapped up at about 2:30. Despite charging for only a few minutes before I headed to the venue, the iPhone 15 still lasted the whole day — even after streaming music for several hours as the bridal party was getting ready. 

Still, it’s worth noting that long battery life is typical of new smartphones, since the battery is fresh. As Apple explains on its website, a battery’s capacity decreases as it ages. The battery in the iPhone 15 I’ve been using still has 100% of its maximum capacity, while the one in my 3-year-old iPhone 12 is down to 86%. 

In addition to anecdotal information on battery life, CNET reviewers run two battery tests on smartphones: a 45-minute general usage test and a 3-hour video streaming test. The general test is meant to see how much everyday tasks like scrolling through social media and making a video call drain the battery. The second test shows how video streaming taxes the device’s battery. We measure the phone’s battery life every hour during the streaming test.

Take a look at the results below to see how the iPhone 15 and 15 Plus fared during these tests.

iPhone 15 and 15 Plus Battery Life

iPhone 15 iPhone 15 Plus
45-minute test From 100% to 95% From 100% to 98%
Video streaming test 1 hr: 97%; 2 hrs: 91%; 3 hrs: 85% (60Hz) 1 hr: 99%; 2 hrs: 94%; 3 hrs: 89% (60Hz)

The iPhone 15 can replenish 50% of its battery in 30 minutes using a 20W adapter, while the 15 Plus can refill the same amount in 35 minutes, according to Apple. The iPhone 15 Plus seems to line up with that, charging from 20% to 67% in 30 minutes. The regular iPhone 15, on the other hand, went from 20% to 73% in the same period of time, also aligning with Apple’s estimates.

The iPhone 15 and 15 Plus support 7.5W charging when using a standard Qi wireless charger and 15W when using a MagSafe charger. And the difference is very noticeable. The iPhone 15 Plus refilled only 5% of its battery after charging via a Qi wireless charger for 30 minutes. But when using a Belkin MagSafe wireless charging stand, it went from 65% to 86%. The smaller iPhone 15 charged a bit faster when using a Qi wireless charger, going from 15% to 28% in 30 minutes. But like its larger sibling, it replenished its battery much more quickly when charging via MagSafe. After half an hour, it went from 28% to 50%.  

The iPhone 15 makes it easier to find your friends

You’ve been able to share your location with other iPhone users for years, but Apple took that a step further with the iPhone 15. Apple’s new phones include a feature called Precision Finding for Find My, which literally points you in the right direction of the person you’re trying to find. 

However, this works only if both parties have an iPhone 15, since the feature requires Apple’s new ultra wideband chip. That limits its appeal, since you can’t use it unless your friends and family members also happened to upgrade their phones recently. 

Still, I imagine it’ll become standard in new iPhones moving forward, which means it could become handy over time. It’s Apple’s way of giving iPhone owners yet another reason to stay within the iOS ecosystem instead of switching to Android.

I tried this out with one of the only other people I know who has an iPhone 15: my husband, who also happens to be a tech journalist. To put it to the test, I told him to hide in a random aisle in our local grocery store while I waited outside. It took a few moments for the iPhone to lock onto his location, but it led me to the exact aisle in a matter of minutes. 

Camera, Dynamic Island and other features

I covered the new 48-megapixel camera, Dynamic Island, USB-C and general performance in my initial review of the iPhone 15. But I have some additional thoughts to share now that I’ve spent more time with the device.

The Dynamic Island can be helpful for multitasking. Though I don’t use it to keep tabs on my Uber’s ETA as much as I thought I would, I do use it whenever I’m squeezing a workout into my lunch break during the week. It lets me keep Slack open on the screen so I don’t miss anything important while still allowing me to jump to the next track in my Spotify playlist. 

The switch to USB-C has been really convenient, although there are some instances in which I find myself digging for a Lightning charger to power up accessories like my Magic Mouse. But another cool thing I’ve tried since publishing my initial review is hooking up my iPhone to my work monitor using a USB-C to HDMI cable. It’s not as smooth and optimized as Samsung’s Dex mode, since it essentially just mirrors the iPhone’s screen. I can’t imagine why anyone would use this method instead of AirPlay, but it does work. 

The A16 Bionic processor feels quick and snappy, just as you’d expect. I ran two benchmarks on the iPhone 15 and 15 Plus: One called Geekbench 6 for measuring everyday performance and another called 3DMark Wild Life Extreme for testing graphics performance. The iPhone 15 scored higher than the iPhone 14 on both tests.

The new 48-megapixel camera is a major upgrade compared with the camera in older phones like the iPhone 12. I shared some camera samples in my initial review, but here’s another one to underscore my point. The photo on the left was taken with the iPhone 15, while the one on the right was shot on the iPhone 12. There’s so much more contrast and detail in the iPhone 15’s image compared with the iPhone 12’s.

Overall thoughts

The iPhone 15 is a welcome upgrade for folks with older phones. The Dynamic Island finally helps Apple’s standard iPhone catch up to Android when it comes to multitasking; the camera feels significantly improved; and battery life is long enough to get you through a day and then some. 

My initial criticisms also still stand: I’d love to see the regular iPhone gain an always-on display, since that feature is considered standard across almost every other smartphone in 2023. Precision Finding for Find My would also be much more useful if it worked with more iPhone models. 

But overall the iPhone 15 is a great choice for people who are committed to Apple’s ecosystem, are upgrading from a phone that’s more than two years old, and don’t need all the iPhone 15 Pro’s bells and whistles.

Wild Weather Ahead: Here’s How 2024 Is Shaping Up After the Hottest Year on Record

The climate crisis is impacting communities around the world. Here’s what to know about dealing with extreme weather in 2024.

We just lived through the hottest year since recordkeeping began more than a century ago, but before too long when we look back at 2023, it might not stand out as the pinnacle of extreme heat. 

That’s because it’s unlikely to be the only hottest year that we experience. Our climate is changing, growing warmer due to the emissions from burning fossil fuels, and our weather is changing with it. It’s possible that this year may turn out to be hotter still.

In March, scientists from the EU’s Copernicus Climate Change Service said February 2024 was the hottest February according to records that stretch back to 1940. The news came on the heels of their report in early January that, as expected, 2023 was indeed the hottest year on record. Temperatures closed in on the critical 1.5-degree Celsius rise above preindustrial levels, after which we will see irreversible damage to the planet. These aren’t freak outliers: The extreme heat we’re experiencing is something we’ll need to be prepared to deal with on a much more regular basis, along with storms, floods and drought.

Later in March, the US National Oceanic and Atmospheric Administration issued its spring outlook, predicting that most of the continental US and Alaska will see above-average temperatures from April through June. The risk of flooding, it said, will ease during the three-month period because of «historically low winter snow cover» in large parts of the country.

A key trend highlighted by the US government’s Fifth National Climate Assessment, published in November, was that climate change is provoking extreme weather events across the country that are both more frequent and more severe. It pointed to an increase in heatwaves and wildfires in the West over the past few decades, the increased drought risk in the Southwest over the past century and more extreme rainfall east of the Rockies. Hurricanes have also been intensifying, as those who have found themselves in the path of a storm know all too well.

You’ll need to be prepared. Extreme weather is going to have a widespread impact on industry, society and individuals. Last year in the US there were 25 extreme weather events with losses amounting to over $1 billion that resulted in the deaths of 464 people. People lost their homes, saw personal property damaged or suffered mental and physical health issues.

Three months into 2024, we’re staring down the barrel of another potentially record-setting hot year. If there’s a silver lining, it’s that the US is now better prepared than ever and we know what steps you can take to better deal with these unwelcome events. When it comes to weather, forewarned is forearmed. 

The US has been taking active steps. The Biden administration has provided funding to build resilient communities, and a new (as of September 2023) National Climate Resilience Framework, which should provide the US with a whole range of protections. These include conserving water resources, modernizing and strengthening the electric grid against weather and disasters and building infrastructure to protect communities and ecosystems from sea level rise, tidal flooding, hurricanes and storm surges.

At home and in your community, you can take steps, too, including preparing your home for wildfires and flooding and recognizing signs of heat-related health issues. This way, when wild weather comes calling, its impact on our homes, health and livelihoods is minimized.

Forecast 2024

Last year’s heat was no anomaly. It’s part of a long-term trend: The last 10 years have been the 10 warmest on record, according to NASA, with most of the Earth’s warming taking place over the last 40 years. Most forecasters are anticipating yet another year of extreme heat ahead.

«If we look at the forecast for the next three months in the long range, it’s suggesting that the trend that we’re seeing in baseline warming could continue, and so 2024 could rival 2023 for being the hottest year on record, which is very scary,» says Chloe Brimicombe, a heatwave researcher at the University of Graz.

Some of the extreme weather we experienced in the latter half of last year and will continue to experience in the first half of this year is a result of El Niño, a cyclical climate event that sees unusually warm ocean waters that has a knock-on effect of warmer temperatures and increased rainfall across the southern part of the US. For instance, temperatures in Death Valley, California, peaked at 128 degrees Fahrenheit in July, while forecasters predicted warmer temperatures in northern parts of the US stretching into February and a colder, wetter winter for Southern states.

While meteorologists are able to make long-term predictions about El Niño, other climate-related predictions are trickier. «All things told, we’re going to see an increased prevalence of heat events across the globe, but we can’t tell right now exactly where that will be,» says Andy Hoell, a climate scientist at NOAA.

What we do know, he adds, is that the climate crisis can compound events such as extreme heat or extreme rainfall to make them more likely or more severe. 

In the past, it wasn’t always easy to draw direct links between extreme weather events and climate change. But huge improvements in attribution science (the ability to specifically identify emissions as the cause for unusually dramatic weather) in recent years have changed the game. The World Weather Attribution program, based at Imperial College London, has now completed nine studies on droughts, heatwaves, wildfires and heavy rainfall in North America. «Every study found that climate change made the event more intense and more likely,» says Ben Clarke, a researcher at WWA.

The speed at which climate scientists are able to identify human-caused climate change as the culprit for extreme weather has also dramatically improved. Last year alone, Climate Central was able to attribute record-breaking spring heat in the western US, and ongoing extreme heat stretching through the summer in Texas and Florida, to climate change as it was happening. «It’s much more impactful as far as our understanding of what climate change really is if we can make that connection in real time,» says Andrew Pershing, vice president of science at Climate Central, a climate science analysis non-profit.

Thanks to attribution science, we can confidently point to a heatwave we’ve experienced and say whether climate change played a role in making it happen. But it also helps us to recognize that extreme weather events we’re experiencing are part of a pattern – one that can’t be broken without tackling the root causes of the climate crisis. «Until the world moves away from fossil fuels and reduces emissions to net zero,» says Clarke, «extreme weather events in North America will continue to become more intense, more dangerous and more deadly.»

Even if you live in a region that hasn’t yet directly been impacted by a climate-linked weather event, you’re not off the hook.

«As the climate continues to warm, most areas will be at an increased risk of some types of climate-linked extreme weather,» says Russell Vose, chief of the Monitoring and Assessment Branch at NOAA’ National Centers for Environmental Information and one of the NCA’s authors. «Perhaps the best example is extreme heat – it can occur anywhere.»

He points to the scorching heat dome that descended on the Pacific Northwest in June and July 2021, which was unprecedented in the historical record. The unpredictable nature of such extreme heat means no regions are marked as safe.

In fact, a region that’s been lucky enough to not yet experience an extreme heat event is more likely to experience one in the future and suffer more greatly due to lack of preparedness, according to a study published by scientists from Bristol University last April.

Scientists are more concerned about the ability of people in areas that don’t usually get intensely hot to cope when their turn comes. «What worries me would be something in the Upper Midwest or the Northeast that just hasn’t had a major heat event for a few years,» says Pershing. «I think we kind of lose a little bit of that muscle memory.»

Weather’s unequal impacts

The weather might not discriminate when it comes to who gets hit, but that doesn’t mean its impacts are experienced equally by all groups across American society.

«Certain groups are simply more vulnerable to extreme events due to geographic, socioeconomic or demographic factors,» says Vose. He points to the extreme rainfall brought by Hurricane Harvey in 2017, which led to a large number of homes being flooded in Harris County, Texas, with a disproportionate impact on low-income Hispanic neighborhoods.

When a heatwave hits, it will feel hotter in high-density urban environments that are more likely to be occupied by people of color or people living in poverty than in more spread-out neighborhoods or rural areas. Then some are homeless and can’t access health care. They have little ability to protect themselves, no matter how much warning they get about an incoming heatwave. This makes these groups much more vulnerable to the health risks of extreme heat.

Heat researchers are extremely concerned about people who live in housing not resistant to warm temperatures, says Brimicombe, who points out that those who rent are especially at risk. «If you’re a tenant, you have less ability to adapt your house to extreme heat than if you’re a homeowner,» she says. «And that also means young families, because babies are vulnerable to extreme heat.»

Not only are economically disadvantaged communities in the US more susceptible to feeling the worst impacts of extreme weather, but they have also done the least to contribute towards the climate crisis in the first place. A study published last August revealed that the wealthiest households in the US are historically responsible for 40% of the country’s climate emissions.

Meanwhile, these same households have more tools at their disposal to protect themselves from the impact of climate-related weather events. In 2019, The New York Times reported that wealthy California residents were banding together to hire private firefighters to protect them from the impacts of wildfires.

The Biden administration is well aware that marginalized and minority groups are hardest hit by climate change, including extreme weather. At the beginning of his term, the president set up the White House Environmental Justice Advisory Council, made up of leading experts from the US climate justice community.

Last September the group published its policy recommendations urging the government to ensure climate disasters do not further or exacerbate harm to vulnerable populations and communities. 

«Disaster relief should never be the cause of deepening inequality in any neighborhood, region, or Tribal community,» the council wrote in its recommendations. «When disaster hits, the goal of government should be that the people hit the hardest should emerge stronger and more secure than before, not the opposite.»

It recommended a number of measures that would help protect people in case of extreme weather including the creation of a low-cost national flood insurance and the establishment of a «Just Relocation Fund» that would provide communities hit by climate impacts with a relocation process based on a dignity framework with respect for their human rights. 

The White House has yet to respond to the recommendations, but if it does act on them this would hopefully prevent a repeat of the aftermath of Hurricane Katrina in 2005, in which Black communities were allocated less money to rebuild their housing, resulting in a lawsuit against the federal government.

Through the Bipartisan Infrastructure Law and other initiatives, the Biden administration is investing heavily in adaptation, mitigation and resilience measures designed to protect all Americans from the impacts of climate-linked extreme weather. As with all funding, people may have to wait some time to feel the full impact of that funding. In the meantime, there are a number of steps you can take to keep yourself safe in the months ahead.

How to weather the weather, whatever the weather

Summer’s not so far off, meaning sizzling days are on the horizon. 

Intense heat poses some scary risks to our health, including heat cramps, heat exhaustion and heat stroke, which can be life-threatening. It’s important to familiarize yourself with the signs so that you’ll recognize them in yourself and others, and can therefore seek medical attention if necessary.

Remember that heat is more likely to adversely affect older people, children and babies, and those with preexisting health conditions. There may be cooling centers or other well-air-conditioned places in your community where you can take refuge – if you do, consider taking elderly or vulnerable neighbors with you. «Look out for friends and families,» said Brimicombe. «Don’t be complacent.»

The British writer and fellwalker Alfred Wainwright is widely credited as coining the phrase, «there’s no such thing as bad weather, only unsuitable clothing.» Wainwright, who died in 1991, didn’t live through the kind of consistently bad weather we’re experiencing in this era of extreme heat, but that doesn’t mean we have nothing to learn from him. In the midst of a heatwave, it’s best to wear loose-fitting clothes in light colors, rather than black, which absorbs the heat.

Make sure you stay hydrated and try to spend as little time as possible outside in the sun. Try to block sunlight from warming your house, and consider buying reflectors to place in your windows that can help keep the heat out. At nighttime, take note of when it might be cooler outside than in, and use this to your advantage by opening doors and windows to let the internal temperature of your house regulate. Fans can be effective, but at very high temperatures they’re likely to just start pushing the hot air around – in which case you should, sparingly and without putting too much pressure on the grid, resort to air conditioning, or moving to your local cooling center.

Remember that global warming is worldwide, so the same heat warnings apply even if you plan to travel to other parts of the world over the summer. The heat waves that hit the US in the summer of 2023 also impacted areas of Europe, including popular vacation spots in the Mediterranean. Countries including Greece, Spain and Italy were all affected by wildfires that resulted in the evacuation of locals and tourists alike from some areas and islands.

The surge in Europe-bound American tourists that occurred in 2023 is expected to continue this year, but if you’re planning to be among them it’s important not to travel without comprehensive insurance. Likewise, if you’re traveling in the peak months of July and August, be prepared to adjust your itinerary in case of extreme heat to ensure you’re not putting your health at risk. This may mean spending more time indoors than you’d planned for the sake of your health.

For other types of extreme weather that may hit your property such as wildfires, storms or floods, it may be useful to have an evacuation plan. You should prepare an emergency evacuation bag, also known as a go bag or a bug-out bag. Don’t forget to plan for your pets. The National Fire Protection Association has a handy guide on how to prepare your home for wildfires

One of the easiest but most important things you can do is keep an eye on long- and short-term weather forecasts. The silver lining for people in the US, says Pershing, is that the country has great weather forecasting capabilities and the channels to communicate incoming events to people so you can prepare. «The gaps are really whether you take it seriously yourself,» he says.

So for anyone who does take it seriously, be sure to read our tips on how to prepare yourself and your home for wildfires, hurricanes, floods and storms.

SpaceX Calls Mission 3 a Success, Despite Losing Starship: How to Rewatch

On its third attempt, SpaceX launched its Starship and cruised into space, but lost the rocket after reentry to Earth.

SpaceX launched its third Starship mission on Thursday, with the space exploration company owned by Elon Musk forging ahead after the first two attempts exploded after takeoff. SpaceX considers those first two missions successful, thanks to the data it was able to collect, and the third mission was the most successful of the bunch.

Shortly before 9:30 a.m. ET Thursday, the company posted three words to the Musk-owned X social media site: «Liftoff of Starship!» A 36-second video showed the rocket engines igniting and then Starship rising amid a cloud of exhaust smoke and up into the sky.

But the rocket did not complete the round trip, as you can see by rewatching the full test flight. «The ship has been lost. No splashdown today,» Dan Huot of SpaceX communications said on the stream. «But we were able to get through some of the early phases of reentry.»

SpaceX quality engineering manager Kate Tice noted on the stream that SpaceX wasn’t intending to recover Starship anyway, and had been planning to crash it into the ocean. 

Starship is arguably the most ambitious effort for Musk, who owns the satellite-based internet company Starlink along with X, EV maker Tesla and the neurotechnology company Neuralink. The Starship missions are critical to SpaceX’s — and Musk’s — goal of getting to and eventually settling the moon and Mars. 

With a new flight trajectory and hopes for new data insights, the space company’s third mission may prove to be its most important yet.

When did the Starship mission launch?

Starship’s third mission launched on March 14. It had been pending favorable weather and a license from the Federal Aviation Administration.

How to rewatch Starship mission 3

SpaceX set up livestreams for watching the third mission. One was the SpaceX account on X, and another was the SpaceX third mission landing page. You could also watch via CNET’s YouTube channel.

You can rewatch the launch on X, on the mission 3 page, or via CNET’s YouTube stream embedded here.

What SpaceX achieved in Starship mission 3

SpaceX’s third Starship mission was designed to test whether the spacecraft can complete certain tasks. After liftoff, the company planned to open Starship’s payload door and transfer its propellant from one part of the vehicle to another. For the first time, SpaceX also attempted to relight its Raptor engine while in space, a test that could be critical for future missions as it eventually tries to propel Starship through space.

Starship took a different flight path this time around, and had planned to land in the Indian Ocean instead of the Pacific Ocean until it lost the vehicle after reentry. In a statement, SpaceX said that the new flight path was designed to maximize «public safety,» but the company didn’t discuss how. 

The new flight path also paved the way for SpaceX to try «in-space engine burns,» a reference to the company attempting to reignite the Raptor engine in space.

«Huge congratulations to the entire team for this incredible day: clean count (glad the shrimpers could get out in the nick of time!), liftoff, hot staging, Super Heavy boost back and coast (and likely a couple engines making mainstage during landing burn!), clean ship ‘insertion’ and coast, payload door cycling and prop transfer demo (to be confirmed!), and ship entry!» SpaceX President Gwynne Shotwell posted on X following the launch, naming the successful components of the test.

The mission was slated to last for 1 hour, 15 minutes. Previous missions, if completed, would have lasted 90 minutes.

What happened in the previous missions?

April mission: Forced detonation

The first Starship mission launched in April 2023. Early on in the mission, the two stages of Starship — the reusable upper stage, called Starship, and its Super Heavy first-stage booster — were supposed to separate. That didn’t happen, and for safety reasons, the SpaceX team was forced to detonate the vehicle just 4 minutes into the mission.

November mission: Explosion due to liquid oxygen

In November 2023, Starship launched on its second mission. That time around, Starship was able to separate its two stages and it reached nominal first-stage engine burn. However, Starship exploded 8 minutes after launch when it tried to vent its liquid oxygen. Oddly, the explosion may not have needed to happen. Earlier this year, Musk said on a real mission carrying payload — meaning the materials a spaceship carries to perform its scientific mission — liquid oxygen wouldn’t be onboard.

«Starship’s second flight test achieved a number of major milestones and provided invaluable data to continue rapidly developing Starship,» the company wrote on its site. «Each of these flight tests continue to be just that: a test. They aren’t occurring in a lab or on a test stand, but are putting flight hardware in a flight environment to maximize learning.»
