Is iPhone 6s running iOS 15 ok?

iPhone 6s, also known in the technology world as the 'Immortal King'. The reason for such a name is because since 2015 until now, iPhone 6s has been continuously updated and most recently iOS 15.

So why and for what reason did Apple decide to let the iPhone 6s go up to iOS 15? If you are also asking the same question, let's find out through this article!

I. Brief introduction of the iPhone 6s

Released in 2015, at that time, the iPhone 6s was rated as one of the top TOP smartphones in the world, it was equipped with Apple A9 chip, 1.85 Hz and up to 1.96 GB of RAM, giving it a completely different powerful experience compared to iPhone 5s, 6 and 6 Plus versions.

Touch ID 2nd generation reads extremely fast, 3D Touch screen brings many conveniences during use, in addition, the device has been integrated with Live Photos: this is more related to emotions and for me it's so worth it.

Even at that time, if anyone used an iPhone 6s, they were confident that there was no need to upgrade to iPhone 7, because it brought a far superior experience, from battery life to performance.

Performance has dropped a bit but not significantly and on top of that, the iPhone 6s has a 3.5mm jack for headphones, while the iPhone 7 does not.

However, the battery of the iPhone 6s is 1,715 mAh, the capacity is less than the iPhone 6, but the battery life is the same.

II. Review iOS 15 on iPhone 6s

This is a machine that frankly is quite old and outdated, but if it is worth talking about at the present time, it is still OK.

#first. The battery

Not much more to say about this issue, the burning problem for all iPhone users today is the battery life.

In this respect, there is no doubt about it, with a battery with a capacity of only 1715 mAh, the device will consume the battery like drinking water.

But if you compare the battery life through the iOS 14 and 15 updates, it's almost negligible. So if your device is on iOS 14 and you want to upgrade to iOS 15, don't worry.

According to some information, the battery of iPhone 6s max screen brightness on:

1. iOS 14: Duration is 6 Hours 38 Minutes.
2. iOS 15: The duration is slightly reduced to 6 Hours 22 Minutes.

#2. Visibility

Then I highly appreciate the display on iOS 15 with a maximum brightness of up to 625 nit, equivalent to the brightness of the current iPhone 11.

In terms of visibility on iOS 15, I rate it as better than iOS 14 from color, image quality ., no screen error or plaid like some iOS versions in the past. .

#3. Usage performance

In my opinion, the performance of iOS 15 is quite stable, feels much smoother and more comfortable than iOS 14.7.1. However, sometimes when playing games, the device will get a little hotter, in my opinion, the disadvantage is that.

With performance score:

1. iOS 14.7.1: 549 s-core vs 1024 m-core.
2. iOS 15: 552 s-core vs 1044 m-core

#4. What's new in iOS 15 on iPhone 6s

1. New set of wallpapers.
2. There is more customization in do not disturb mode. Here we see Apple has updated to add more customization features for users.
3. Besides, the iPhone 6S iOS 15 version also has a new Safari interface, I quite like this new interface with the dork bar integrated with convenient tab switching, especially for those who use it for work.

III. Epilogue

Yes, through the things I shared above, the only problem with the iPhone 6s running iOS 15 is the battery life and the hot condition, but in general, this is the general condition of the older machines. So it's not too surprising
