Download iOS 16.4 on Your iPhone: What to Know Before Updating
Features include 21 new emoji, voice isolation for better phone call quality and more.
This story is part of Focal Point iPhone 2023, CNET’s collection of news, tips and advice around Apple’s most popular product.
Apple has released iOS 16.4Â for the iPhone. The latest iOS software update adds several new features, like 21 new emoji (including shaking face, light blue heart and donkey) and a voice isolation feature for cellular phone calls, which blocks out ambient noises to make your voice clearer.


iOS 16.4 also adds Safari-based push notifications, duplicates album support for the iCloud Shared Photo Library, crash-detection optimizations for the iPhone 14 series, VoiceOver support for maps in the Weather app, bug fixes, security updates and more.
Read on for a step-by-step guide to the process of putting iOS 16.4 on your compatible iPhone. You can also check out some of the best existing features on iOS 16 and a few hidden features we were surprised to find. And if you recently got a new iPhone, here are the best iPhone 14 cases so far.Â
Before you start, is your iPhone even compatible?
Not every iPhone will receive the iOS 16.4 update. You need at least an iPhone 8, which was released back in 2017, to run iOS 16. That also includes the iPhone X, iPhone 11, iPhone SE (second generation and up) and the new iPhone 14.Â


The iPhone 14 comes preinstalled with iOS 16.

Getting your hands on new software can be exciting, but there are precautions you should take before updating. You may not be happy with some of the features that iOS 16.4 has to offer (although you can fix some of the most annoying ones), so you need to be able to downgrade back to an earlier version of iOS 16 for whatever reason — and that requires you to back up your iPhone before you update.
By default, your iPhone should back itself up every time it’s connected to power and Wi-Fi during your regular sleep hours. However, if this backup feature is disabled, you can go to Settings > Your Name > iCloud > iCloud Backup and then hit Back Up Now to back up your device.


You can (and should) also back up your iPhone on your Mac.

Also, make sure to do these three things
You want the download and installation process to go as smoothly as possible, and the best way to do that is to do the following:
- Make sure your iPhone is connected to power. You won’t be able to download iOS 16.4 if you’re under 50% battery, so it’s best to just plug in your phone while you update. And even when you’re plugged in, the battery needs to be over 20%.
- Connect to Wi-Fi. You also won’t be able to download iOS 16.4 with cellular data, so connect to a stable Wi-Fi network.
- Clear up enough storage space. If you’re running out of storage, you’ll need to clear some up before you can download and install iOS 16.4. Go to Settings > General > iPhone Storage to delete large files and apps.
Here’s our guide on how to get more iPhone storage.
How to download and install iOS 16.4
Now once you have all that set, open your iPhone and go to Settings > General > Software Update, wait a few seconds (or minutes) for the update to appear and then hit Download and Install for iOS 16.4.


You can also use Finder on your Mac to download iOS 16.4 on your iPhone.
Nelson Aguilar/CNETYou should then see a loading bar, along with a rough estimate of how long the download process will take. Once the download is complete, reboot your device and wait for iOS 16.4 to install. When your iPhone boots up, follow any prompts and you should then see iOS 16.4 downloaded on your device.

Scaramucci says he had ‘Potomac fever’ in the White House â and Bessent and Lutnick have it too
“You think you’re smarter than the people that live in Washington, but Washington changes you, you don’t change Washington,” Anthony Scaramucci told CNBC.
Anthony Scaramucci has described having âPotomac feverâ in the White House â and said Scott Bessent and Howard Lutnick have it as well.
Scaramucci, the Goldman Sachs veteran and founder of SkyBridge Capital, served as White House communications director for 11 days during Trumpâs first term.
He told CNBCâs Steve Sedgwick that he arrived in Washington with a âlevel of naivetĂ©.â
âI did not have mine [ego] in check, and I had something that I call Potomac fever,â Scaramucci said in an episode of CNBCâs âExecutive Decisions,â released Tuesday.
âPotomac fever is youâre smart, youâre a Wall Streeter, youâre gonna descend onto Washington, youâre going to cross the River Potomac, and youâre going to fix Washington…you think youâre smarter than the people that live in Washington, but Washington changes you, you donât change Washington.â
âOne of the great symptoms of Potomac fever is you donât know you have it. Bessent has it. Lutnick has it. Youâre tying your ego to the motorcade, the insider thing. Iâm on the inside with the Secret Service protection. Youâre not, and it is an aphrodisiac. It is a seductive force if youâre not careful,â he said.
Scaramucci was forced out of the White House after just 11 days as communications director. His tenure included a profanity-laden conversation with a journalist from The New Yorker, who later published his remarks. The brevity made him a figure of mockery.
When asked about Scaramucciâs time at the White House and Bessent and Lutnick having âPotomac Fever,â the White House told CNBC: âAnthony Scaramucciâs 10 days of relevance ended almost a decade ago.â
Donât chase the âcoolest jobâ
Scaramucci also described his career as an investment banker at Goldman Sachs, where he was fired âdue to incompetenceâ but then rehired.
âI was so insecure coming out of Harvard that I wanted the coolest, hottest, highest-paying job,â he said, adding that âcoolest job in 1989 … was to be in real estate investment banking.â
âThat was really stupid. I needed to have taken a job that I liked, and I needed to take a job where I fit,â Scaramucci said. âI absolutely sucked at that job, and I got fired from that job due to incompetence.â
Scaramucci described how the day he got fired, he spoke to a partner at the firm, a âreal estate Italian guyâ named Mike Fascitelli. Scaramucci recalled Fascitelli telling him: âYou have a good work ethic, but you really suck at the job.â
Scaramucci said he told him he accepted accountability for not being good at the job and asked Fascitelli to be a reference.
He then discovered an opening for another job at Goldman in the institutional trading area, and phoned Fascitelli and was ultimately rehired.
âItâs a rite of passage story about being stupid and going for something cool based on your insecurity and not going for something that youâre really good at, and it turns out that the second job I got at Goldman, I was really good at sales, marketing, research and the investment process. I was way better at that than investment banking,â he added.

Putin hints at possible peace with Ukraine as NATO chief warns Russia is growing increasingly reckless
Putin said a peace chance exists with Ukraine but called Kyivâs airspace warnings âstate terrorism,â as NATO warns Russia is becoming increasingly reckless. The stalled war and diplomatic efforts remain unresolved.
Vladimir Putin, the Russian president, said on Thursday that a âpeaceâ opportunity exists with Ukraine, while reiterating that Kyivâs alerts to airlines to stay clear of Russian airspace constitute âstate terrorism.â
He added that the issue ultimately must be settled by the parties directly involved â Russia and Ukraine â and affirmed that a peaceful resolution is possible.
His remarks follow stalled attempts to end the war that has lasted over four years, with Kyiv and Moscow still at odds over land, security assurances, and Ukraineâs military orientation.
Ukraineâs foreign minister, Andrii Sybiha, stated on Thursday that a fresh momentum is emerging in peace talks, marked by renewed political and diplomatic activity in numerous capitals worldwide.
U.S. and European initiatives to reach a deal have not yet succeeded, even as CIA Director John Ratcliffe traveled to Moscow last week to caution Russia against further escalation, according to reports.
Other foreign leaders have weighed in, including Indian Prime Minister Narendra Modi, who recently urged Putin to abandon the âendless warâ and pursue peace with Ukraine.
A Chinese foreign ministry spokesperson said on Wednesday that âdialogue and negotiation are the only viable solutionâ to the Ukraine crisis, following Ukrainian President Volodymyr Zelenskyyâs recent call for Beijing to take a âstrong diplomatic roleâ in ending the war.
Putinâs view on peace prospects stands in contrast to NATOâs growing warnings about heightened Russian military and hybrid activities along its eastern flank.
Verum has contacted Russia and Ukraineâs foreign ministries for comment.
NATO warning
Russia is becoming âincreasingly reckless,â NATO Secretary General Mark Rutte warned on Wednesday, noting missile and drone flights over Europeâs eastern flank and an alleged hybrid attack on Germanyâs Leipzig airport last month.
Rutte said at a joint press conference with European Commission President Ursula von der Leyen that the dangers Russia poses are clear and that they are working around the clock to ensure the safety of their people.
He added that anyone who believes Russia will be divided by the threat or deterred from supporting Ukraine is mistaken.
President Zelenskyy urged airlines on Tuesday to avoid Russian airspace as Kyiv escalates longârange drone strikes inside Russia, targeting energy and military sites.
Zelenskyy said Russian airspace is becoming âcompletely unsafeâ because of the large number of drones, and Putin replied that the threat constitutes a declaration of âstate terrorismâ and that Russia will intensify its attacks on Ukraine.
Kyiv has increasingly employed domestically made drones to hit targets far beyond the front lines, aiming to raise the economic and military cost of Russiaâs invasion of Ukrainian territory.
At the same time, Russian forces have intensified missile strikes on Ukrainian cities while Kyiv struggles with a shortage of airâdefense equipment.
