Suggested January 2024 What This Iphone 13 Case Can Tell Us About Apple’s Next Smartphone

We examined some iPhone 13 cases from a trusted vendor in search of evidence backing up claims that the upcoming Apple smartphone might see some noteworthy design changes.


Overall, iPhone 13 design remains the same as its predecessor

A camera bump cutout hints at much larger lenses out the back

iPhone 13 may not have Touch ID embedded in its power button

Taking a closer look at Totallee’s iPhone 13 cases

Most of the rumors mention minor design changes, with a few notable exceptions.

According to the rumor mill and reliable analysts like Ming-Chi Kuo, most of the iPhone 13 innovation is saved for a completely redesigned rear camera system on the back. With that in mind, we’ve decided to dress up our iPhone 12 in an upcoming iPhone 13 case from Totallee to see if we could spot any notable differences to tell you guys about.

So we went hands-on with these upcoming iPhone 13 cases from a California company, dubbed Totallee, that specializes in ultra-thin minimalist cases for iPhone. Totallee has been successfully releasing iPhone cases ahead of Apple’s event since 2013.

The overall design stays the same…

Totallee’s cases suggest iPhone 13 design hasn’t changed much from that flat-edged look of the iPhone 12 family. Flat edges are here to stay, which is great. We should get a bit narrower notch and the entire phone could be a bit thicker at 7.57mm. If true, the difference between the new models and iPhone 12 ones, which come in at 7.4mm thick, could be indiscernible.

Cutouts for the volume buttons and the ringer switch on the left side show that even though existing cases may fit iPhone 13, the experience of using them leaves a lot to be desired.

…But the camera bump has swelled

Focusing on the case’s rear side, we can instantly tell that the rumors mentioning a massive camera bump for iPhone 13 are probably true. This is corroborated by cases from other vendors. As you can see for yourself, the rear camera cutout extends to more than half the width of the phone, and all the lens cutouts seem to have increased in diameter as well. With a camera bump that large, there’ll be no mistaking iPhone 13 Pro Max for its predecessor.

No Touch ID power button for you?

With iPad Air 4’s fullscreen design and no Face ID, Apple had to put a fingerprint sensor somewhere—that’s how we got a Touch ID power button. We heard whispers the same thing might happen with the next iPhone, but that doesn’t seem to be the case (pun intended).

The unchanged shape of the cutout for a power button seems exactly the same as that on the current iPhone 12 model. Rather than an elongated power button with an embedded fingerprint reader, this case seems to hint at an iPhone 13 without a Touch ID power button.

Why Totallee?

For the tenth year in a row, Totallee has cases for Apple’s next smartphones ready. Just to be clear, the branding-free minimalistic design along with the dimensions of the iPhone 13 case pictured in this article have all been confirmed by Totallee’s vendor.

One of the nice touches that immediately jumped at us, save for that huge camera bump, is a raised camera ring on the back of the case. That’s extra protection for when your iPhone is laying flat on a table—the phone will still wobble because of the camera bump but at least the sapphire lens covers won’t be making direct contact with the surface.

This isn’t a sponsored article, but we can honestly claim you won’t regret buying one of these minimalist cases from Totallee, especially if your goal is for the beauty of your iPhone 13 to show off through a thin, light case that practically doesn’t add any bulk.

What The 1918 Flu Pandemic Can Teach Us About Covid

In some ways, an early 20th century event doesn’t provide a great analogue to how a modern disease might evolve. 100 years ago we didn’t have widespread air travel, nor did we have antibiotics, which can’t treat a virus but can help with the infections that often accompany respiratory diseases (and cause many of the deaths in a viral outbreak). 100 years ago, we didn’t even know what viruses were.

But one aspect of pandemics remains even a century later: non-pharmaceutical interventions. That’s the technical term for the non-medical precautions that governments and other organizations put in place to prevent the spread of an illness—in other words, social distancing measures. Closing schools and museums would be one non-pharmaceutical intervention. Implementing quarantines is another. And by looking at how the 1918 influenza progressed in various cities, we can see how the interventions they each took impacted the spread of the virus.

One classic example is the distinction between Philadelphia and St. Louis, as conveyed in a PNAS paper from 2007.

We can all learn from St. Louis Infographic by Sara Chodosh

On September 28, the flu had already been spreading across Philadelphia for at least 10 days—but the city went ahead with its Liberty Loan war-bonds parade anyway, in which roughly 200,000 people lined Broad Street. Cases took off just a few days later, and by the time the city took measures to fight back on October 3 it was already too late. Philly ended up with one of the deadliest flu outbreaks in any major American city.

St. Louis, in contrast, saw its first cases on October 5 and shut down most of the city two days later. In doing so they seem to have spared their citizens the worst of the disease.

This is an excellent case example, but of course it’s just one. To figure out whether that trend holds up, another research group looked across 43 cities in the continental US to examine whether early social distancing measures actually helped. And in a case of science confirming what is perhaps obvious based on common sense, they found that, yes, unequivocally, taking early precautionary interventions did help cities reduce deaths.

The peak death rate tended to be lower in places that acted early, whereas those that waited a week or more saw higher spikes. Of course, the data aren’t perfect—St. Paul, MN and Grand Rapids, MI both had very low peak death rates despite waiting weeks to implement any measures. Conversely, New York City started shutting down more than a week before the virus hit, yet still had a moderate spike in deaths. That’s perhaps no surprise given how densely packed NYC is compared to other American cities, and it could have been much worse.

But despite these anomalies, the trend still held: taking early action prevented deaths.

Similarly, the earlier cities acted, the lower their total death counts were in general. Keeping peaks low likely kept health care systems from getting totally overwhelmed, and therefore enabled them to provide better care to each patient. The situation right now in Italy (and previously in China) exemplifies how quickly even a good system can get overrun, forcing health care providers to make tough decisions about who gets care and who doesn’t. A shortage of ventilators meant that patients who needed help breathing simply couldn’t get it. And in the US we’re likely to face even worse. An estimate from Johns Hopkins University stated that we’d likely need 740,000 ventilators to care for patients in a pandemic like the 1918 flu. We currently have 160,000, plus nearly another 9,000 in stockpile—not nearly enough to cover everyone.

We’re heading into tough times, in which we’ll have to make difficult decisions. The least we can do is try to learn from our past while we still have time to act.

Taking action early really is effective Infographic by Sara Chodosh

But the timing of early interventions doesn’t tell the whole story. Some cities, St. Louis included, implemented school closures and bans on public gatherings early, then released them as it seemed the danger was over. But the flu often rushed back as soon as interventions lifted. Denver and St. Louis both saw spikes in cases after they lifted their bans. None of the cities that kept their bans in place saw that second wave (really, a third wave—the fall of 1918 was already the second, deadlier wave in the pandemic).

Taking action early really is effective Infographic by Sara Chodosh

Our medical knowledge and typical way of life may have changed drastically in the last century, but the way viruses spread from person to person hasn’t—and neither has the effect of social distancing. Cities hoping to contain the spread of COVID-19 shouldn’t be waiting to implement those measures until it gets bad. By then, it’s probably too late.

Note: A previous version of the first chart incorrectly labeled the peak point on the line. That label has been removed.

What Brain Science Teaches Us About Conflict Resolution

Five years into teaching conflict resolution to elementary school students, Linda Ryden realized she was missing the mark.

“On the surface, it all looked good. But day after day I would see children, often some of our most vulnerable and troubled students, being sent to the office for fighting at recess,” Ryden, a peace teacher at Lafayette Elementary School in Washington, DC, writes for EdSurge. “Some of these kids would go straight from my classroom where we had been role-playing how to work out a conflict to the playground where they would get into a fight over who goes first on the swings.”

Despite all her work, Ryden concluded that her students simply couldn’t think clearly enough to make good choices when confronted with the actual moment of conflict. She went back to the drawing board, and found that the neuroscience of anger—the role of the amygdala in “hijacking” the brain’s higher-order skills, like self-control, for example—provided useful context for her students. Once they understood this framework, students quickly adopted the language of brain-based learning, Ryden says, with one student approaching her to insist that he was “all amygdala” and needed help with his self-regulation.

But understanding how anger works isn’t enough, Ryden knew. She had never been a meditator, she admits, “but as I was searching for ways to help my students I kept reading about mindfulness—in particular, breathing strategies that can calm us down in the moment. There isn’t much research about its impact on students, yet, but what is out there appears promising.”

The two strategies—the neuroscience of anger and the self-regulatory power of mindfulness—snapped together in a way that felt immediately useful. “Once I was able to teach my students what was happening in their brains when they were angry and how they could take care of their brains with mindful breathing, then working out the conflict was a breeze,” she says. “Giving my students these tools quickly began to change their lives, my life, and the climate of the school.”

Making It Tangible for Kids

To help her students understand what happens in their brains when they get angry, Ryden made a puppet using a mitten, googly eyes, and pompoms. The puppet is a tangible way to show her students what happens when their prefrontal cortex—the part of the brain responsible for thinking and executive function—goes offline when kids get angry and their amygdala—the part of the brain responsible for responding to threats and danger—takes over and begins making decisions for them. She realized this visual tool could be an important part of her practice after watching Daniel J. Siegel, a clinical professor of psychiatry at the UCLA School of Medicine, use his hand to demonstrate what happens in the brain when we get angry.

Once her students, beginning as early as first grade and continuing through fifth grade, gain a basic understanding of what’s happening in their brains, Ryden begins teaching tools they can use to literally calm their brains. She does this by teaching them different techniques for taking deep and calming breaths, such as take 5 breathing, for example. “Neuroscientists have found that the act of taking deep breaths sends a message to your amygdala that everything is OK, that your amygdala can stand down and let other parts of the brain take over,” Ryden says, noting that this is a simplified explanation of a very complex process. “Then you can deal with the problem that’s causing you to be upset.”

Integrating Mindfulness During the School Day

At Lafayette Elementary, Ryden says teachers give students opportunities twice a day for what she calls “mindful moments.” This daily frequency and repetition is important because teaching, learning, and practicing mindfulness isn’t a quick fix. “It takes a very long time for people to change their patterns and how they behave,” she says. In class, teachers refer to a poster with nine different ways for students to practice mindfulness. These include gravity hands (sitting with hands palms up, breathing in while slowly lifting hands, then breathing out while slowly dropping them, palms down) and squeeze and release (tensing up muscles while breathing in, relaxing muscles while breathing out).

“A lot of mindfulness practice isn’t about calming down,” says Ryden. “It can be applied to life’s challenges in so many ways. The goal shouldn’t be: ‘These kids are out of control, let’s get mindfulness in here.’ Rather, it should help you understand yourself better, how you think about things, and eventually, help make the world a better place.”

Is Your Smartphone Overheating? This Is What You Should Know

How it all started?

I think the present wave of consumer panic started with Xiaomi Mi3. It was the perfect smartphone one could ever dream of at 13,999 when it was launched and gave Xiaomi a solid head start over other Chinese brethren, but it had one issue. The Aluminum frame heated up abnormally with what is considered day to day usage. I don’t remember anyone asking me about heating issues in a  phone prior to purchase before that.

Xiaomi’s best selling Redmi 1S was no exception either. In fact, Xiaomi had to later roll out an OTA update to fix the heating. Also with the transition to 64 bit world, Qualcomm hastily made some tradeoffs and we saw chipsets like Snapdragon 810 and Snapdragon 615, adding more fuel to the fire.

Moreover, Consumers have grown a strong linking to slim smartphones, and slim profile, with metal and glass backs, combined with more densers batteries inside, can make your phone feel even hotter. Some well known cases being Gionee Elife S5.5 and Canvas Knight A350.

How much is too much?

Image source – Tweakers What are causes of smartphone heating?

Processor – The number one culprit these days are the chipsets as mentioned above. Smartphones with Snapdragon 615 and Snapdragon 810 are world renowned for haphazard heating (though things will improve with next gen Snapdragon 810 and 820), but these are not the only culprits.

If your battery is old and your phone has started heating up in the region around the battery rather easily, you should replace the battery.

Poor Signals – Poor cellular reception or even attempting to download apps and other stuff on a weak WiFi or Bluetooth Signal needs your smartphone to do more work and can cause excessive heating.

Extended usage – Recording videos at high resolution can heat up all phones within 10 minutes. Also extended calling say for hours can cause your phone and even your brain to heat up beyond what is considered safe.

What are long term drawbacks if my phone heats up too often?

Heat is the numero uno enemy for all electronic devices. It can lead to variety of damages, but with smartphones, you should worry more about the damage to your battery rather than motherboard. If temperature raises to an alarming level, your phone will display a warning and switch off (just like laptops do).

Impact on battery –  Apparently, heat is a threat to your phone battery. If the temperature is often above 40, some researchers claim that your battery will lose 15 percent of the charge within a year. In day to day usage, temperature is mostly around 35 ℃ in our experience. While that’s in theory and in practice there is no way to confirm how much damage you will incur as it largely depends on your usage. Most people upgrade their phones every couple of years and if not, a software update arrives which blows away the battery backup out the window either way.

Impact on performance – Excessive heating in chips like Snapdragon 615 and Snapdragon 810 can however lead to poor performance. If the temperature rises CPU throttles. Which means it your processor starts running at a reduced clock frequency, which slows down your phone. If temperature rises quickly, this can happen within minutes. This is the drawback that will irk you most and more often.

What should i do if my phone is uncomfortably hot way too often?

Put it in safe mode – If your smartphone was running cool for sometime and has only recently started heating, put it in safe mode (press power key and long press power-off option). If it is running fine now, a rogue app is most likely the cause. Boot it again and uninstall all recently installed apps.

There is nothing much you can do on your own.

Wrap up

we have seen people paranoid about their phones heating up even when they shouldn’t. It is wiser to check reviews and ask for guidance before you purchase your next smartphone. It is a genuine concern, but still, every phone heats up today and you shouldn’t panic if temperature rises once in a while.

Apple’s Iphone Headed For Enterprise

plans and support for independent developers via a software development kit (SDK).

Heading the list of enterprise-friendly features is support for Microsoft’s Exchange server. Apple (NASDAQ:AAPL) announced it is working with Microsoft (NASDAQ:MSFT) to build support for Exchange directly into the iPhone to satisfy the needs of business users, who want to be able to receive their corporate e-mail, contacts and calendar information from company servers, and IT departments who want to be able to manage it.

Apple said it will be supporting Microsoft’s ActiveSync protocol so the iPhone will work directly with corporate Exchange servers rather than what it said is the more complicated extra layer of communicating with a remote network operation centers (NOC)s (define), which devices like RIM’s BlackBerry rely upon. “That’s a more complex scenario that takes money and support and adds risk and reliability from time to time as we know,” said Apple’s vice president of worldwide marketing, Phil Schiller, in an apparent reference to a recent RIM outage that lasted three hours.

“I don’t think anyone has fundamentally redefined the UI on mobile devices more than Apple,” he added. “A lot of the other phone manufacturers know how to tie features to buttons, but Apple’s redefined development from hardware to software. That’s disruptive.”

Jobs ceded most of the speaking time here at the company’s headquarters to other Apple executives and independent software developers, including chúng tôi which showed versions of their applications tailored to run on the iPhone.

An enterprise-ready iPhone?

Schiller said that, while the iPhone is “an amazing device,” there have been a lot of things “holding it back from being huge in the enterprise.” He then ticked off a series of features that enterprise companies felt would make the iPhone more appealing to big companies. Apple plans to deliver all of these features in the software update due out in June.

Heading the list is “great e-mail integration” with push e-mail from servers. Similarly, he said enterprise customers want calendar and contact information pushed out to their devices, a standard feature of RIM’s BlackBerry devices. IT departments will also be able to use Exchange Server to remotely wipe the iPhone clean or inoperable should it be lost or stolen. Rounding out the list, the iPhone will provide access to global address lists, built in support for Cisco’s IPSec (network security), VPN and certificates.

The finished iPhone SDK isn’t out yet. Today, Apple released a beta version of the iPhone SDK, with the full version and commercial availability of applications built using these new tools, slated for June. A new Apple App Store will be launched online this June as the exclusive way for developers to distribute applications built using the SDK. Apple CEO Steve Jobs said the App Store would insure Apple has a measure of quality control and security over what applications get distributed. He claimed the goal isn’t to make money for Apple but to sell more iPhones.

“This is the best deal going for distributing mobile applications,” said Jobs.

The deal is that developers get to keep 70 percent of whatever they want to charge for their applications, while Apple keeps the remaining 30 percent for hosting, marketing and distribution. The developer doesn’t have to pay for credit card or other transaction fees. If they want to offer applications for free, there’s no charge. Jobs said this is the best way even the largest developer could hope to reach every iPhone user. New applications and categories will be featured much as music titles are on Apple’s iTunes store.

Jobs said Apple will only restrict distribution of certain applications like pornography and any “malicious” programs that spread viruses or malware. A few other categories he didn’t mention but that were shown on the screen were “bandwidth hogs” and “Unforeseen.” Jobs also said Apple will be able to track anyone that distributes malicious software allowing the company to “turn off the spigot” and distribution. “We can track who did it and tell their parents,” joked Jobs.

What Is Macbook ‘Thermal Throttling’ And What Can I Do About It?

You might have heard that the latest MacBooks are a hot item. Literally. The controversy surrounding CPU thermal throttling in recent MacBooks may have cooled down, but there are probably more than a few still asking what “thermal throttling” is in the first place. Is it a big deal? Does it even affect you? Surprisingly, the answer isn’t black and white. The (rather touchy) topic of MacBook thermal throttling requires a slightly deeper look at the inner workings of your laptop to fully understand.

Which MacBooks are affected?

In principle, any MacBook (or really any high-performance laptop) can be affected by thermal throttling under the “right” circumstances. However, some models have been particularly likely to exhibit a case of heatstroke.

Most recently, MacBooks Pro models from both 2023 and 2023 have shown severe throttling issues. In the case of the 2023 MacBook Pro 15-inch and 13-inch (with Touch Bar) models, a now-fixed firmware bug was the culprit. We ran a poll, asking our readers whether Apple should make a thicker MacBook to solve thermal issues in future models. The results were in favor of a chunkier MacBook with more thermal headroom. Unfortunately, the 2023 15-inch MacBook Pro showed that Apple still had to take aggressive measures to keep the temperatures down.

In this case, however, it wasn’t throttling, but a lowered voltage from the factory, which indicates that the core problem of limited thermal headroom is still stalking the MacBook Pro line. This may very well be one of the main reasons Apple is strongly moving towards using its own cool-running ARM processors instead.

What causes a MacBook to thermal throttle?

Energy in the form of electricity is the magic that makes a computer work, but the byproduct of doing work with that energy is heat. Some portion of the electricity your CPU uses to do all those calculations is wasted and heats everything up. This is a bad thing because there’s a temperature range within which the circuitry works properly and, of course, very high temperatures where the materials that make up the CPU itself could be damaged.

The manufacturer specifies a temperature range that should never be exceeded if you want your CPU to last for its full natural lifespan. The exact numbers vary from one CPU model to the next, but every CPU has a limit.

When you ask the CPU to do something that requires most or all of its processing power, heat starts building up rapidly. The cooling system of your MacBook kicks in to move that heat away from the CPU and out of your system. Usually, this cooling system involves a metal heatsink directly attached to the CPU package and a fan system that moves air over that it, so that the built-up energy can be transported into the room instead.

Current MacBook Pro status:

If the cooling system is doing its best, but the temperatures keep rising, throttling is next on the list of remedies to stall the road to heat death. When thermal throttling happens, the CPU slows down below its base clock speed to stop short of hitting the maximum temperature specified by the CPU maker. The result is a cooler CPU, but also one that’s slower than it’s meant to be.

How to mitigate MacBook thermal throttling

With the exception of throttling caused by a bug, there are a few things you can do to prevent your MacBook from getting so hot that it needs to give itself a temporary lobotomy to cope.

Give it space to breathe

There needs to be enough airflow around the machine to let it move air through the system. Which means making sure all air vents are clean and unobstructed. Heat also leaves the laptop through the body itself, so it can help to put your MacBook on a stand to optimize how much surface area gets good airflow.

Learn acceptance

In the end, however, thermal throttling may simply be the price one has to pay in exchange for an incredibly thin and light form factor or acceptable fan noise. While a throttled CPU may perform worse than it’s on-paper minimum levels, that lower performance level could still be perfectly adequate in practical day-to-day work. This means that throttling is only a problem when, well, it’s actually a  problem.

Upgrade or change laptops

Finally, your best bet might be to upgrade or change laptops. Our own Jeff Benjamin noted in his look at the 2023 MacBook Pro earlier this year that that particular model tended to keep from throttling a bit better than others:

Although throttling will always play a role in space-constrained laptops, I find that the CPU in the 2023 MacBook Pro stays at or above its base clock speed while under load. Of course, it won’t be able to turbo boost for extended periods of time, but that’s to be expected.
