I have been an owner of the iPhone 15 for 6 months, so I can have an objective opinion about this smartphone.
First, I will start with the 6.1-inch screen; I find it satisfactory for one-handed use as well as for being able to fit it in a pocket. It is a compact phone, and this is convenient. The screen resolution is very good with 460 pixels per inch, and the colors are realistic, not exaggerated like Samsung does.
The battery, with the milliamp hours provided by the company, is good. When you hear 3350, you roughly think it won't last, but it lasts a day with moderate use. With heavy use, a second charge will be needed in a day. It is simply a satisfactory battery; it could be better, of course. The charging time is a bit slow, taking from 1.5 to 2 hours from 0 to 100.
The speaker is very good, stereo with good volume without making noise or distortion at high volume.
The camera is above average; it is good, not like that of the 14 Pro Pro Max, since they have the same megapixels but a different sensor, so if you compare them, you will see various advantages for the 14 Pro Pro Max.
For someone who wants a photographic phone and for video, they should go for the Pro series or switch to another brand. For the average user, the 15 covers them fully, even in night shots.
The 6 GB of RAM is just fine; the phone does not lag, it is smooth, and it is very fast. The A16 Bionic responds very well and still has a lot of potential for future iOS updates. In short, if someone does not want to change their phone often, this will last them a total of about 5 years satisfactorily.
The refresh rate could have been 120 Hz, but it would drain the battery a lot, as happens with the 15 Pro, so that is where someone might compromise.
Also, I would like an always-on display; this generally helped me, and I was somewhat surprised that it doesn't have one, as it is good to have all notifications in front of the screen rather than having to open it to see.
The Face ID is good and fast, but in very low or very high light, it gets confused; it could use an additional improvement in this area.
The 128 GB is just satisfactory; it would be better to have 256 GB for someone who wants to store videos and files that take up space. You can simply use Drive and other means to store them there so that it doesn't get overloaded.
The build quality is good, like most Apple models; it is a bit thick for its size and could be considered heavy for its size.
iOS is a lightweight operating system that does not overload each phone with various applications and functions that take up unnecessary space upon opening the phone, with additional stores that overload it and require 12 GB of RAM to respond, and with 3 updates, crashes may start. Here, iOS excels for anyone who wants a simple, minimalist operating system.
For the 880 euros that the 15 is sold for, the question is whether it is worth it for someone to pay that much upfront for what it offers, if it is value for money.
Objectively speaking, 880 and even 800 euros, which it is sold for here, is a lot for this phone. Yes, it is fast, has a good camera, the battery is mediocre to good, the screen is not 120 Hz, and it will not get AI in the future; the money is a lot.
If you find it used in good condition for under 600 euros, then it is worth getting it, and I mean until the first quarter of 2025, because after that, the price should drop further, especially when the 17 comes in September
