Detailed review of iPhone 7 to iOS 14.4

So what will the  iPhone 7 look like  when updating to iOS 14.4? Please read the article detailed review iPhone 7 to iOS 14.4 below offline.

1. Is performance on iPhone 7 on iOS 14.4 improved?

In this section, I will compare the performance of the iPhone 7 when in iOS 13.6.1 and when to iOS 14.4 through two ways, which are benchmark scores (AnTuTu Benchmark and 3D Mark) and real gaming experience. health.

The first is the score, with the software AnTuTu Benchmark, I got the results as shown below. As you can see, the score changed slightly from 177,653 to 182,800 (an increase of more than 5,000 points). As for the 3D Mark app (in the Sling Shot test), our iPhone 7 when updated to iOS 14.4 also had a slightly improved score compared to iOS 13.6.1, specifically from 1,985 to to 2,410.

Of course, the number cannot say all, so I will play the experience of 3 titles: Lien Quan Mobile, Call of Duty and PUBG Mobile on the iPhone 7 (in both iOS 13.6.1 and iOS versions. 14.4). Thanks to that, it will help you easily compare whether the performance of the iPhone 7 is better after updating iOS 14.4 or not. Details about the FPS chart, the adjustable graphics level in each game, I will in  this link .

With Lien Quan Mobile, after updating iOS 14.4 for iPhone 7, the graphics level that I can adjust will still be the same as before I updated, there is no significant change. But the average FPS is in the range of 30-40, while the average FPS in iOS 13.6.1 is 60.

This is not too confusing because the iPhone 7 is an old model, the more iOS is updated to a higher version of iOS, the performance will decrease a bit. The Lien Quan gaming experience on the iPhone 7 is also affected a bit when the lag occurs more often.

Going to the next game Call of Duty, my iPhone 7 is not showing very well. Specifically, before in iOS 13.6.1, iPhone 7 when playing Call of Duty has a FPS fluctuation in the range of 50-60 FPS. But after the update, my iPhone 7 can only play at 30 FPS. 

However, in the process of playing Call of Duty on the iPhone 7 (running on iOS 14.4 version), I found that the character control operations, moving back and forth are still very good, there is something to aim to take down the opponent. is a little more difficult.

Finally, the PUBG Mobile game, I noticed that the results were not much better. After updating to the latest iOS version, when playing PUBG, when playing PUBG, there was a lot of lag, I found it very difficult to defeat the enemy even though I tried to hold my mind but failed. 

As in the FPS chart that I have measured, before the update, the iPhone 7 playing PUBG is much more stable. Specifically, the FPS in iOS 13.6.1 is always stable at 30, but in iOS 14.4, this number ranges from 25 to 30 FPS.

Before finishing the performance, I note to you that my iPhone 7 when I got to iOS 14.4, the overheating condition is not present even though I use the machine with many different heavy tasks. It must be said that the device is less hot than iOS 13.6.1. In addition, when I perform operations such as swiping, opening apps, scrolling up and down, ., the response speed of iPhone 7 running on iOS 14.4 is quite fast, smooth and low latency.

2. Will iPhone 7 with the age of nearly 5 years have battery life like when it comes to iOS 14.4?

Surely what many of you are most concerned about when updating iOS is battery life. It seems that the 'quick battery drain' has become one of the indispensable 'specialties' every time Apple releases a new iOS update. So with iPhone 7 running iOS 14.4, the device has a faster battery drain than iOS 13.6.1? To answer this question, I will perform the battery test on both iOS versions with the following conditions:

1. Experience 4 rotating tasks including: Play Lien Quan, watch YouTube, surf Facebook and use Safari.
2. Each task uses 1 hour.
3. Screen brightness: 100%.
4. Plug in wired headphones throughout and turn on the volume to 100%.
5. Turn on WiFi and social media notifications.
6. Do not turn on battery saver, screen adaptive, GPS and Bluetooth.
7. Dot from 100% to 0%.

Thus, the question above has been answered, iPhone 7 after updating to iOS 14.4 has a faster battery drain compared to version 13.6.1. Specifically, you can see that right from the second task is to watch YouTube and later on, the battery drops faster and faster. However, in my personal opinion, the iPhone 7 inherently has a relatively weak battery life compared to most  smartphones  today. Therefore, we can not expect that the battery on iPhone 7 will be improved after updating iOS.

Besides, we also measure the time to fully charge the iPhone 7's battery (from 0% to 100%) in both iOS 13.6.1 and iOS 14.4 versions. I used the charger included in the box and the results I obtained are as follows:

Thus, the iPhone 7 after iOS 14.4 is not only improved in performance but also in charging speed. With iOS 13.6.1, I had to wait about 2 and a half hours to fully charge the battery on the iPhone 7. But with iOS 14.4, I can save a little time to fully charge the iPhone 7 battery.

3. New features in iOS 14.4 that the iPhone 7 is enjoying

Scanning QR Code with small size

Inherently, the scanning feature of QR Code with the camera on the iPhone is already very cool, I have to admit this, guys because just panning the camera through any QR Code, the iPhone will recognize. right. But now with iOS 14.4, Apple has improved this feature to a new level, helping the iPhone can recognize the QR Code with a smaller size, its iPhone 7 is no exception.

Before updating iOS 14.4, my iPhone 7 could not recognize the QR Code, and required me to leave the device close to scan it. But after the update, my iPhone 7 scanned easily even though I kept the device up to 20 cm away from the QR Code.

Healthcare with 'Safe headphones' feature

The next feature that I want to mention in this iOS update is 'Headphone safety'. Maybe some of you say that this feature is nothing new, on iOS 14.3 already exists. But in fact, Apple has made a little change, it has equipped with a warning feature for users if we hear loud sounds from headphones.

For example, when I listen to music via YouTube at volume greater than 90 decibels in the past 7 days, iPhone will issue a warning that I am listening to music at too loud volume and ask me to turn down the volume to avoid danger. danger to the ear. It must be said that this is a quite useful feature for a child who has a habit of listening to music like me (sometimes I adjust the volume too loudly necessary).

Classification of Bluetooth devices

Finally, an indispensable feature in the iOS 14.4 update is the category of Bluetooth devices. If you are someone who regularly connects many other Bluetooth devices to the iPhone that you are using, this feature will be very useful. Here Apple provides us with 5 types of devices including: car stereos, headphones, hearing aids, speakers and other. To access this menu, simply click on the 'i' icon of any Bluetooth device connected to your iPhone.

In addition to the 3 important features above, Apple also mentioned in the iOS 14.4 update that it has fixed a number of bugs such as:

1. The fitness widget may not display updated activity data.
2. Typing may be delayed and word suggestions may not appear on the keyboard.
3. The keyboard may not display the correct language in Messages.
4. Enabling toggle controls in Ease of Access can prevent unanswered phone calls from the lock screen.

But my iPhone 7 before the update did not encounter the above errors and even after the update was completed, the machine was normal. Perhaps the faulty iOS situation is unlucky luck, with one meeting but the other. But if you are using an iPhone 7 and encounter the errors that Apple mentioned, you can update it.

Not stopping there, recently a set of users shared that after their iPhone updated to iOS 14.4, they encountered a crash when starting to charge from 20%. Currently I still do not know the reason why this error occurs, but fortunately my iPhone 7 after updating it does not have this error.

Therefore, if you have updated your iPhone to iOS 14.4 and encountered this error, you can log out of your iCloud account from the MacBook (if you have one), then maybe the error will be fixed. If not, you should bring the device to reputable repair shops to check the situation.

Conclude

Overall, iOS 14.4 is just a minor update from Apple for iPhone users who are having problems with older iSOS versions. I strongly advise you, if you intend to update, do not do so. Firstly, because the iPhone 7 is now nearly 5 years old, the performance and battery will become weaker and weaker if you update to a new iOS. And secondly, because iOS 14.4 is still not really stable, there are still some unnecessary bugs.
