There are many definitions of a flagship phone, but it is the most basic requirement to be strong in all aspects and have no obvious shortcomings. At present, we use mobile phones for longer and longer, which also puts forward higher requirements for the battery life of flagship phones. Recently, some foreign bloggers have conducted a comparative test on the battery life of five flagship models. The results show that Google is the most “crotch-pulling”, and Apple is leading the fault!
The five flagships include the latest Samsung S22 Ultra and S21 Ultra, as well as Apple’s iPhone 13 Pro Max, Google’s Pixel 6 Pro and Xiaomi Mi 12 Pro.

The test method is very simple, mainly using common applications and games in daily life to consume power. At the beginning, the performance of several flagship phones was not much different, and as the test progressed, the “uneven” strength also began to appear. When the Pixel 6 Pro has 1% remaining, other phones are holding on, and the iPhone 13 Pro Max has a solid 33% charge. Even at the end, after the other players fell, the iPhone 13 Pro Max still had more than 20% of the battery remaining, which is really powerful.

The final ranking is as shown above. The iPhone 13 Pro Max takes the top spot with a battery life of about 10 and a half hours, followed by two Samsung flagships, with little difference between the two, followed by the Xiaomi Mi 12 Pro and the Google Pixel 6 Pro at the bottom . It is worth mentioning that the battery capacity of the iPhone 13 Pro Max is the smallest among the five models.

Sony recently launched a new true wireless headset LinkBuds. Different from traditional true wireless earphones, Sony LinkBuds adopts a completely open design. Its overall shape is somewhat similar to a “doughnut”, and users can directly put the “doughnut” into their ears to listen to music.

It is worth noting that this headset has a small “shark fin”-shaped design, which ensures that the headset can be securely fixed in the human ear. In addition, this headset also supports IPX4 waterproof, and supports adaptive volume control, which can optimize the volume according to the surrounding environment.

Thanks to the open-back design, the Sony LinkBuds don’t support noise reduction, nor do they have sponge or silicone ear tips. Some netizens said that this headset does not block ambient sound, so it is very suitable for use in some scenarios where you need to understand the surrounding environment, such as running, cycling or taking public transportation.
At the hardware level, LinkBuds uses a 12mm ring audio driver with a battery life of 5.5 hours, and can achieve up to 17.5 hours of listening time with the charging box, priced at $179.99.

Apple has previously been rumored to launch an iMac with a larger screen in 2022. According to the latest revelations, this iMac with a larger screen size may be called “iMac Pro”, which will be equipped with a mini-LED screen and is expected to be released in June this year.

It is understood that the new iMac Pro will be equipped with a larger screen. Analysts say the screen has about 1,000 backlit partitions and more than 4,000 mini-LEDs. In contrast, Apple’s most powerful Pro Display XDR currently uses a flat backlight system with 576 full-array local dimming zones. Therefore, the new iMac Pro is far better than the Pro Display XDR in various screen parameters.

Aside from the mini-LED screen, the new iMac Pro is also expected to feature a new design similar to the 24-inch iMac. At the same time, the interior uses the M1 Pro/M1 Max chip that has already appeared in the 2021 MacBook Pro. From this point of view, the new iMac Pro will be a powerful product from screen to performance, and for some professionals, this iMac Pro is likely to become a more handy productivity tool.

Since the launch of the Samsung S22 Ultra, the crown of the new generation of Android phones has fallen on this flagship product. But to the great disappointment of Android users, despite the blessing of the new Snapdragon 8 processor, in terms of running points alone, there is still a big gap from the A15.

Tested by well-known IT magazines, the Galaxy S22 Ultra, powered by the new Snapdragon 8 processor, scored 1232 in single-core and 3433 in multi-core, while the corresponding iPhone 13 Pro Max single-core and dual-core are 1735 and 4647 respectively. In the multi-core part, Apple is at least 35% faster.
In the GeekbenchML (machine learning) test session, the iPhone 13 Pro Max equipped with A15Bionic achieved 948 points, while the corresponding Samsung achieved only 448 points.
Of course, for mobile devices, it is not objective enough to judge the performance of a mobile phone simply by running points. What’s more, Samsung’s advantages in screen, camera, operating system, etc. cannot be reflected simply by running points.

According to media reports, the United States is now turning to Russia after years of restricting China, but the reasons are very different. It is reported that since many raw materials for domestic semiconductor production in the United States come from Russia and Ukraine, including elements such as neon gas and palladium, 35% of the palladium in the supply of palladium comes from Russia. More than 90% of palladium comes from Ukraine. The US is urging relevant companies to find alternative sources of purchases as soon as possible to reduce imports from relevant countries.

Peter Harrell, a member of the White House National Security Council, and his staff have been in contact with people related to U.S. chip companies in recent days, but they have refused to disclose relevant details, only saying that the U.S. government is ready for Russia to “invade” Ukraine. “Part of that is working with companies to ensure they are prepared for a supply chain disruption should Russia take action to disrupt supply chains,” the senior official said. “We understand that other sources of these critical products are available and are ready to work with us. (U.S.) companies working together to help them secure and diversify supply.”
It can be seen that the United States is very concerned about the tense relations between Russia and Ukraine, and has the attitude of adding fuel to the fire. The U.S. government has also threatened to impose sweeping export controls on Russia if Russia “invades” Ukraine. Some U.S. politicians have also taken the lead in drafting sanctions against Russia, and the proposed sanctions include Russian President Vladimir Putin.
However, the Russian side has always said that the so-called “invasion” is “baseless” and stressed that the United States and other Western countries have been creating tensions. Ukrainian President Volodymyr Zelensky also expressed his strong dissatisfaction with this. It is very unwise to spread rumors about the relationship between Russia and Ukraine. Russian Presidential Press Secretary Dmitry Peskov said in January that considering that Russia will inevitably respond appropriately to U.S. sanctions, proposing new U.S. sanctions against Russia can be tantamount to proposing to sever ties.
