If you need a keypoint that distinguishes apple and non-apple phone, there is one.
Apple products use exclusively their own operating system. The devices (phones) are made to support their OS and vice versa. Therefore, their devices even when the parts are worse than non-Apple phones have as high performance due to better efficiency. Hence, Apple phones consume less electricity and have no need for bigger battery but still compete with other non-Apple products in terms of operating hours before needing to be charged.
However, since Apple has absolute monopoly, every single app has to follow their own rule. They are the rule maker. They have no need to bend over. Meanwhile, android OS isn't as dominant. This means it is far easier to make android apps over iOS apps. This also means stuff that Samsung phones already have for numerous generations, Apple phones would only recently have it. This is why using Apple phones are like living in North Korea sometimes. I am using Iphone7 and I can not lock my screen in landscape mode and can only lock it on portrait mode which is something samsung phones two generations younger than iphone 7 can do. It's absolutely frustrating using Apple phones and products.
This is not mentioning the costs of Apple products and its Accessories (cables, earphones, etc.) are objectives more expensive than non-Apple phones with similar performance. This can be seen just by visiting my supermarket or electronic stores. There is no argument.
There is also the problem with the auto-slowing down phone performance due to old battery thing. This might not have been a big issue if not for the fact that Apple is designed to make third-party maintenance practically impossible. They want to maintain their monopoly in the accessories and post-purchase services so this becomes a very sensitive issue. You own an Apple phone but you don't actually own the phone.
This is not saying that Android phones are better. Remembering I said about Android is open and everyone can make an app more easily than iOS? Since the devices and OS are not created to support each other as tightly as Apple. Samsung had to invest in better hardwares to overcome this issue. Inefficient use of parts will mean parts have more wastage in operation. This is expressed as more heat, more electricity consumption of battery and since battery is consumed more and recharged more. You will need to replace them more. To illustrate it with a metaphor, if you are a city planner and sole job creator, you can decide where is the major residential area and where the residents will come to work. Hence you can invest in a big highway to handle the traffic from A to B. However, in Android case, you are job maker but not city designer. You can't decide which path the citizens will travel and therefore can not build sufficient roads to handle the traffic which creates inefficiency in the form of traffic jam. This is a bottle neck in the design.
Overall, there are both pros and cons but this phone will be my last iphone. I will never subject myself to the control of Apple again.
Fuck! Stuff Android people can do I have to jail break my phone. How fucking stupid is that?
