When it comes to iPhone, what's the most maddening thing that comes to mind?
I believe that the signal problem will definitely rank in the top three.
The most classic is the "death grip" of the iPhone 4:
If you hold the fuselage with your hand and cover the antenna, the signal will quickly weaken ...
The signal hurdle has been with Apple since the iPhone 4 era.
although the signal problem has been improved with the optimization of the antenna of the iPhone 4S.
However, users who have used it know that the signal performance of iPhone can only be said to be average, not excellent.
Especially after falling out with Qualcomm and using Intel baseband:
The signal has once again become a pain in the hearts of Apple users ...
For example, there are a lot of problems about the poor signal of iPhone.
because of the "disappointing" performance of Intel baseband, Apple is also worried.
Under the trend of 5G, I finally bowed to Qualcomm:
I paid $4.5 billion for a six-year global patent licensing agreement.
and a multi-year mobile phone baseband chip supply agreement.
this wave of apple's massive bleeding is finally with Qualcomm's "second time around".
so, the iPhone 12 series finally uses the Qualcomm baseband and supports 5G.
The signal is really getting better ...
However, a recent test report from a foreign Opensignal team said:
The 5G performance test of iPhone 12 series was completely abused by Android phones!
I have no fluctuation in my heart about such news.
In this test report, they pulled 25 Android phones including Samsung, Yijia, Motorola and LG.
come and have a network speed PK with iPhone ~
Then the result is:
Samsung Galaxy S21 5G won the championship with an average download speed of 56Mbps.
and Samsung models account for 6% of the top 25 5G performers.
I have to say: as the mobile phone manufacturer with the largest shipment in the world, it still has a lot of skills.
of course, our domestic brand one plus also performed well, ranking third.
eh? Why didn't I see the apple?
it's normal not to see it, because in this speed competition, the top 25 are all Android phones ...
The iPhone 12 Pro, which costs nearly 1, yuan, can't even be ranked in the top 1.
It's not even comparable to Samsung A51:
A thousand-yuan machine with a price of only in the early 2' s, which is in the middle of Android.
even if the internet speed of the iPhone 12 Pro is already the fastest among all previous iPhones.
yes, if apple only PK with itself, then the progress is really visible to the naked eye.
For this reason, the Opensignal analysis team also found a special angle to prove the great progress of iPhone 12:
"The speed of iPhone 125G is 2.3 times higher than that of 4G."
"It is more different than when Samsung first-class friends switch from 4G to 5G."
boy, this wave shows the level of emotional intelligence.
Low EQ: the iPhone 12 with the fastest Internet speed is worse than the one at the bottom of Android ...
High EQ: iPhone 12 has made great progress from 4G to 5G, which is greater than all Android's progress from 4G to 5G ~
Jokes aside, the real reason why the Internet signal of iPhone 12 is so hip-jerk still needs to be found out.
The big boss of the OpenSignal analysis team analyzed:
"This may be attributed to Samsung and other Android manufacturers leading Apple in RF design. "
" For example, Samsung's Galaxy S21 is its third-generation 5G smartphone. "
"The iPhone 12 series is the first generation of Apple."
It seems that the baseband of Samsung S21 series is Snapdragon X6:
Compared with the Snapdragon X55 baseband on iPhone 12 series, it is indeed upgraded.
you can be forgiven for not being as fast as Samsung S21 series.
That plus 8T is both Snapdragon X55 baseband, so why does it still have a faster network speed than Apple?
I think this may be due to Qualcomm's own reasons:
Because the one plus 8T processor is Qualcomm Snapdragon 865, and the baseband is Snapdragon X55, and both are 7nm processes.
may be able to give full play to its strength.
on the other hand, the iPhone 12 is A14 processor with 5nm technology, so the "fit" is not high enough.
I think this is one of the reasons why Apple wants to develop its own baseband.
First, you don't have to be strangled by Qualcomm, and you don't have to pay unreasonable patent fees to him.
secondly, the self-developed baseband combined with the self-developed processor will definitely give greater performance.
This can be seen from the MacBook of Apple's self-developed chip M1.
For this reason, Apple even spent a lot of money to buy the whole Intel mobile phone baseband R&D team.
But this is not surprising. After all, Apple CEO also said:
In the past six months alone, Apple has acquired about 2 to 25 companies.
that is, one company will be acquired every two to three weeks on average.
I have to say: you can really do whatever you want with money!
Back to Apple's self-developed 5G baseband, iPhone wants to fill the weakest link.
it does look better and more reliable than purchasing 5G technology from Qualcomm.
Of course, the self-developed baseband is not something that can be worked out in a short time.
at least this year's new iPhone will still use Qualcomm Snapdragon's baseband.
No matter what baseband it is, I only care about:
When I am in the elevator, WeChat on my iPhone won't keep circling (rolling its eyes).
