Device details to experience the iOS 14.5 – iPhone 11 update

As I mentioned above, this is an iPhone that has been with me for over a year. I bought it from February 2020 and calculated that I used it a bit bad, the battery status from 100% to 85% after just 1 year. Well now, I would like to give you a quick point through the parameters of this iPhone 11, as follows:

  • CPU: Apple A13 Bionic.
  • RAM: 4 GB.
  • Internal memory: 64 GB (the version of the memory I’m using).
  • Operating System (before the update): 14.4.2.
The iPhone 11 that I am using has 85% battery status.

According to the above parameters, we can see that the Apple A13 chip is only 1 year old, I believe that my iPhone 11 after going to iOS 14.5 will still be delicious. Follow-up procedure below is clear). Well, the new iOS update has a capacity of about 1.27 GB and the total time for me to complete the update is about 1 and a half hours (because I use the internet at the coffee shop so it takes a bit).

The performance of iPhone 11 after going to iOS 14.5: It’s so smooth!

Since updating iOS 14.5, my iPhone 11 feels smoother and smoother when I perform touch gestures on the home screen or open apps. At that time, I tested the games (Lien Quan Mobile, PUBG Mobile, Call of Duty) on my iPhone 11 to see how smoothly the machine would play. The FPS chart or the graphic settings of each game, I leave it here for you guys.

  • PUBG Mobile

As you can see in the above FPS chart comparison, my iPhone 11, after going to iOS 14.5, has processed the PUBG Mobile game much smoother and more stable than the old iOS version. During my game, the FPS was always maintained at 60 (the pink line followed an extremely eye-catching line), in stark contrast to the unstable FPS chart on the iPhone 11 running iOS 14.4.2.

The reason probably comes from the temperature of the device during my experience. iPhone 11 running iOS 14.4.2 has a hot condition after about 4-5 minutes of playing PUBG (although I leave the average screen brightness), the FPS has dropped continuously (as shown in the FPS chart above). Regarding the graphics settings in the game, I keep the same, before and after the iOS update is the same.

  • Arena of valor

In terms of graphics, Lien Quan Mobile is somewhat inferior to PUBG Mobile, so my iPhone 11 can completely fight well. Comparing the FPS chart in both iPhone 11 running iOS 14.4.2 and iOS 14.5, I commented that there is not too much difference, the FPS fluctuation is not too large.

Summing up for the gaming experience on the iPhone 11 (after going to iOS 14.5), I found the device just got a little warmer, not too hot like in iOS 14.4.2. This shows that this update of iOS has helped the device control the temperature better, while avoiding a quick battery drain.

  • IPhone 11 performance rating

After playing the game, I have also conducted a performance score of the iPhone 11 before and after the release of iOS 14.5 because the number will give us a more intuitive look. The results really surprised me and the following I will share with you:

So in all 3 software, the iPhone 11 running iOS 14.5 has superior results compared to the old iOS version, why the actual gaming performance is so smooth. I was especially impressed with the results in the AnTuTu Benchmark software when the iPhone 11’s performance score (after the update) increased by nearly 30,000 points (429,528 points compared to 403,894 points).

I know the scores are for reference only, but these numbers all show that the performance of the iPhone 11 has improved significantly after reaching iOS 14.5. That is why you do not hesitate anymore, immediately update iOS 14.5 for your device.

Will iPhone 11 to iOS 14.5 drain the battery fast?

The fast battery drain is one of the indispensable specialties every time the iPhone updates iOS, I know you guys are afraid of this problem and I personally am not an exception. To find the answer to the above question, I have measured the battery life on the iPhone 11 running iOS 14.4.2 and iOS 14.5 by using a battery test (according to TGDD standards). The specifics of this test are as follows:

  • Experience 4 rotating tasks including: Chien Lien Quan (Detailed settings), watch YouTube, surf Facebook and use the browser (Safari).

  • Battery health: 85%
  • Each task 1 hour.
  • Screen brightness 100%.
  • Headphone plug and 100% volume.
  • Doesn’t turn on GPS, Bluetooth, battery saver mode and screen adaptive.
  • Open WiFi connection and social media notifications.

And the results I obtained are as shown below:

Battery life of the iPhone 11 running iOS 14.4.2 (above) and iOS 14.5 (below).
Battery life of the iPhone 11 running iOS 14.4.2 (above) and iOS 14.5 (below).

So after my iPhone 11 to iOS 14.5, the battery life has been improved a lot (for an iPhone with 85% battery bottle). Specifically, the iPhone 11 running iOS 14.5 lasted 5 hours 14 minutes and the iPhone 11 in iOS 14.4.2 only lasted 4 hours and 47 minutes after the test (about 27 minutes difference).

Granted, the test is a bit harsh, so I will share with you my actual usage process. Usually my iPhone 11 is always 100% full in the morning and I use it until about 4 – 5 pm to charge once, before going to bed to charge again. However, after going to iOS 14.5, I noticed that the device’s battery had a little buffalo, instead of charging twice as usual, now I just need to charge the device before going to bed.

The article is still being updated and will be finalized on April 29. Have you remembered to it!
