These apps cause the iPhone 15 to overheat


On September 22nd, Apple started sales of its iPhone 15 series. But shortly after the first devices went over the counter, complaints about overheated devices began to increase. Apple explained now that the problem is not with the smartphone itself, but with certain apps and faulty software.

Since the first smartphones in the iPhone 15 series hit the shelves, user complaints have been increasing that the devices were overheating. However, this can happen, especially with new devices, if, for example, updates are running in the background or the cloud is updating.

Smartphones can also generally get a little warmer when you use applications that require a lot of computing power. However, the devices in the iPhone 15 series apparently received an unusually high number of complaints compared to previous models.

Why does iPhone 15 overheat?

Manufacturer Apple has now commented on the reports for the first time. According to a statement to the US news channel CNBC The company let it be known that the problem was not with the devices themselves.

Rather, the iOS 17 operating system contributes to overheating. The same applies to certain third-party apps. Apple said: “We are working with these app developers on fixes that are currently being rolled out.”

According to a report by the AP news agency, Instagram is one of the apps that causes the iPhone 15 to overheat. However, the Meta subsidiary has already reacted and released a corresponding update that should fix the problems.

Updates are intended to fix problems with hot iPhones

But apps like Uber and the video game “Asphalt 9” would also cause devices in the iPhone 15 series to become too hot. According to Apple, unlike Instagram, the providers are still in the process of developing appropriate update solutions.

The iPhone company has not yet given a date for fixing the problem with its in-house software iOS 17. According to Apple, however, there are no security concerns that should prevent iPhone users from using their smartphones while they wait for an update.

The complaints about iPhones getting too hot had previously caused speculation that the new titanium housing or the new processor chip were to blame. However, Apple assured that the titanium frame ensures better heat dissipation. The processor should not be slowed down with the upcoming update.

That’s why the smartphone should be disinfected regularly


Statistics show that the average German citizen looks at their smartphone up to 2,500 times per day. Even if the cell phone is used less often, the fact that millions of germs, bacteria or viruses quickly spread on the surface does not change. The pathogens only survive on a stainless steel or plastic surface for a maximum of three days.
Nevertheless, the organisms have enough time to spread. Smartphone owners should not expose themselves to this risk.

Effective protection of the smartphone surface

Cell phone owners can combat this problem by cleaning the display regularly. However, smartphone users should under no circumstances resort to aggressive cleaning products that contain soap. Otherwise, consumers risk having the surface of smartphones destroyed.

Mobile phone displays have oil-repellent components to effectively protect the surface from grease or fingerprints.

In most cases it is sufficient to use a normal screen cleaner.

Apple recommendations

Cell phone users should avoid using disinfectants because these cleaning products usually only kill bacteria and not viruses. To minimize the possible risk of infection, it makes sense to clean the displays with alcohol-based disinfectants.
The iPhone provider Apple recommends cleaning products that contain 70 percent isopropyl alcohol. Alternatively, Clorox disinfectant wipes are a good choice.

Clean cell phones properly – this is how it works

Before cleaning, smartphone owners should make sure that the devices are not connected to a power source. Before disinfection, it therefore makes sense to switch off the cell phones completely and let the device cool down.

Smartphone owners should also avoid spraying the cleaning agent directly onto the display.

The risk is too high that the liquid will penetrate into the connection sockets or housing openings and damage the inside of the smartphone. To clean the display, cell phone users should best use a soft, lint-free microfiber cloth.
After wetting the cloth with the cleaning agent, you can use it to wipe the front and back. In addition, cell phone owners should also remember to wipe down the smartphone case.

Measures to reduce germ infestation

Some preventative measures effectively counteract the accumulation of viruses, bacteria and other pathogens on your smartphone. This protection begins with small steps. For example, it is important not to carry your cell phone with you in particularly dirty areas such as public toilets.
After applying lotion to their hands, consumers should only pick up the smartphone again when they are dry. Otherwise, oily residue will form on the display, which will promote the formation of bacteria. In addition, smartphones don’t belong on the dining table.

400 km range with 10 minutes charging time


The Chinese battery manufacturer CATL recently presented a new super battery. The promise: A range of around 400 kilometers with just ten minutes of charging time.

Electric vehicles are becoming increasingly important. But in order to achieve the federal government’s climate goals in 2045, further incentives are needed. There are apparently still major concerns about electric cars in this country. As a result, buyers choose a classic gasoline or diesel engine.

At least that’s what data for 2021 shows. According to this, only 13.6 percent of all newly registered vehicles had an electric drive during the survey period. The leader Norway, however, achieved a rate of 63.7 percent in the same year. For most car buyers, range concerns and too long a charging time are likely to speak against a purchase.

New battery from CATL promises fast charging time

However, Chinese battery maker CATL recently unveiled a new super battery that could put these concerns to rest. The so-called “Shenxing Superfast Charging Battery” promises an extremely short charging time. According to the manufacturer, appropriately equipped vehicles can travel up to 400 kilometers after just ten minutes.

However, this only applies to a charge from around 20 percent to around 80 percent. The so-called C rate is 3.6 – CATL generously rounds up to a value of four. The C-rate indicates how quickly a battery can be fully charged. With a value of 1C, it is possible to charge a battery from zero to 100 percent within an hour.

More efficient charging processes in extreme ambient temperatures

The new technology promises further progress. Because at relatively more extreme temperatures below minus ten degrees Celsius, the battery reaches a value similar to that of a VW ID.3 under ideal conditions. The energy storage is based on LFP cells and does not require expensive raw materials, including nickel and cobalt. This leads to a relatively low price level.

CATL also presented a new graphite anode. This determines the efficiency with which a load is transported. Production of the battery is scheduled to start this year. Experts expect the first corresponding vehicles for the fourth quarter of 2024.

This is the largest electric container ship in the world


The Chinese shipbuilder Cosco has launched an electric container ship with a length of 120 meters. The cargo ship is said to be the largest of its kind. It can be up to Transport 700 containers.

Shipping continues to be responsible for a large proportion of emissions in the transport sector. One reason for this is that electrifying large ships is often unprofitable. With each additional battery, the weight increases, so the range remains limited.

Nevertheless, some companies are not giving up on the venture. This is also due to the ambitious climate goals that many nations have set themselves. The Chinese shipbuilder Cosco has now put an electric container ship into operation for the first time. It is intended to show the practical suitability of the technology.

Electric container ship transports up to 700 containers

In everyday life, the ship with the serial number N997 now transports up to 700 standard containers over a 1,000 kilometer route. Since it has a draft of just 5.5 meters, it can be used in coastal areas as well as on rivers. Cosco is therefore initially using the model on the Yangtze River.

The ship currently weighs around 10,000 tons. The capacity of the batteries on board is around 50 megawatt hours and the motors drive N997 with an output of 900 kilowatts. By using batteries, the company wants to avoid up to 32 tons of CO2 every day.

Battery change in port

The advantage of the electric container ship lies in its structure. Because the batteries are housed in 36 containers. This allows empty batteries to be easily discharged and newly charged batteries to be charged. Stays at ports are significantly shortened. However, the ship also loses five percent of its capacity.

Another ship (N998) is already under construction. By testing battery technology, the decarbonization of shipping could gain momentum. Nevertheless, there is still potential for improvement before a regular container ship is put into operation. A classic freighter has a capacity of up to 20,000 containers.

Snap terminates employees of acquired Berlin AI startup


Snap’s Venice Beach, California office.

At the Berlin startup Fit Analytics, all employees have been laid off. The start-up scene learned this from corporate circles. It is said that the layoffs affected a higher double-digit number of employees. The company specializes in the AI-based calculation of clothing sizes and was taken over by the US social media group Snap just over two years ago. The Snapchat mother paid the equivalent of around 124 million euros for the takeover.

Snap stomps AR department

Snap has not yet responded to a request from Gründerszene. However, the group said in a statement that it had largely discontinued its activities in the area of ​​augmented reality. “After exploring our options over the last few months, it became clear that we would need to make significant additional investment to expand our enterprise offering for retailers. “We simply cannot afford these investments at this point,” said Snap founder and CEO Evan Spiegel. As a result, 170 employees were separated.

Lost cell phone? This is what you should do if you lose your smartphone


Have you lost your cell phone or had it stolen? We’ll explain what you need to do to protect your data and your wallet.

Smartphones have become a constant companion for many. Whether for communication, navigation or paying in the supermarket – the smartphone supports you in many situations. It’s even more annoying when your cell phone is lost or stolen. We’ll show you what you have to do in such a case.

This is what you should do if you lost your phone

Losing your smartphone is not only annoying, but can also quickly become quite inconvenient and expensive. Therefore, if you have lost your cell phone, the first thing you should do is have your SIM card blocked.

You can do this either with your network provider. But the emergency number 116 116 can also help you here. There you can not only have your money and credit cards or the online function of your ID card blocked, but also your SIM card.

You should have this information ready

However, to be prepared for such a case, you should write down some information in advance. The consumer advice center advises you to write down the following numbers in case of an emergency:

  • your own phone number
  • the number of your SIM card
  • your customer number and your customer password

The consumer advice center also advises you to write down the IMEI number of your cell phone. You can identify your smartphone with the 15-digit serial number. If you want to report your cell phone as stolen to the police after it has been lost, for example, you will also need this number.

You can find your smartphone’s IMEI number using the key combination *#06# – you have to type this into your phone and then click on call. Your smartphone will then show you the device information.

Lost cell phone: This is how you prevent the dangers of losing it

In addition to regular backups, you should also protect your data directly on your smartphone. You can do this, for example, using the screen lock. This makes it more difficult for criminals to unlock your cell phone and get your data.

You should also make sure that you can locate your smartphone remotely. This way you can track down a lost phone if in doubt.

Many smartphone providers such as Apple or Samsung also allow you to lock the smartphone remotely or delete the data.

Is this air battery better than lithium ion battery?


Researchers from Japan have developed an air battery that works without metal electrodes. Although the new battery is not yet suitable for practical use, it could drastically extend the lifespan of batteries in small electronic devices in the future. The backgrounds.

Batteries should have a high capacity, last a long time and, ideally, be environmentally friendly – and at the lowest possible price. Lithium-ion batteries are primarily used for electronic devices such as smartphones, laptops and tablets. However, research is making efforts to continually extend their lifespan.

One approach is air batteries. In the past, scientists have celebrated some successes in this area. Now a group of Japanese researchers has apparently achieved a new breakthrough.

Air battery stores many times the power of previous batteries

Like the Japanese research group led by Kenji Miyatake in the science magazine applied Chemistry reported that they have developed a new type of air battery. It contains organic molecules and solid electrolytes.

Scientists have already tested lithium-air batteries before. With more than 1,000 milliamperes hours per gram, they store several times the amount of electricity of conventionally available lithium-ion batteries. However, they used liquid electrolytes and only had a low cycle stability. The researchers from Japan now want to solve these problems with their prototype.

Air battery consists mostly of organic elements

To do this, they do not use electrochemically active metallic electrodes and thus avoid the formation of sharp dendrites when charging and discharging the battery. “A proof-of-concept study was carried out for a rechargeable air battery (SSAB) with redox-active 2,5-dihydroxy-1,4-benzoquinone (DHBQ) and its polymer (PDBM) as well as a proton-conducting polymer (Nafion),” the release says. These are mainly organic substances.

According to the researchers, the polymer PDBM in particular supports the discharge capacity of the air battery. It achieved a gravimetric capacity of 176.1 milliampere hours per gram. After 30 charging cycles, the research group was still able to demonstrate a capacity of 78 percent.

In fact, these values ​​show that the air battery from Japan is far from being ready for practical use. However, the practical test of the prototype proves for the first time that an air battery with solid electrolytes actually works.

New battery from Japan could power electronic devices for longer

In order to make the new air battery usable in everyday life, the research group must, among other things, further increase the cycle stability. Theoretically, up to 60,000 cycles are possible with a capacity of 200 milliamp hours per gram. “The air batteries had a high performance that was close to the theoretical maximum capacity,” the researchers said in their article.

If the Japanese scientists improve their development even further, the air battery could extend the lifespan of batteries in small electronic devices such as smartphones and tablets in the future. According to Miyatake, it should also contribute to the realization of a carbon-free society.
