1 year ago, performance and gaming of s23 ultra both were more than 95 points, now they are below 90 !!! just by 1 year. s23 ultra processor isn't a joke and even if it will fall a bit it should never drop under 90.. i have never tried any of the phones, my phone is s22 ultra snapdragon... i think s23 ultra is better, (edges are not as sharp as s24u, width is less (makes it easier to grab the phone).. the only advantages of s24 ultra are : higher brightness and reducing light reflection, flat screen.

I'm not sure about other regions, but at least in Asia, specifically in Arabic countries and India, the S24 Ultra comes with a dual SIM version.

Losing the 10x zoom camera was a major loss. The performance improvements were significant, but would you say that the S23 is a slow phone?

No, not at all, the S23 is more than enough for anyone's needs. Therefore, this is going to be a challenging year for the S24 to rival its predecessor. Hopefully, software updates can compensate for these shortcomings.

Big squeeze, No, because the S23 has a terrible PWM unlike the S24, and it ultimately doesn't have that curved display. Also, a better CPU is always preferable. I bought the S24 Ultra and it surpasses it.

No. The S23 Ultra CPU performance is on par with an i7 Intel 11th gen CPU, which is fine for normal office work even in 2025.

Why do phone scores tend to decrease a year after their release whenever a new Samsung phone launches? This is especially true when looking at performance and battery life. This suggests that a Samsung phone loses its value in just one year. If this isn't the case, these scores might not be accurate and may be influenced by the reviewer.

These scores appear to be quite random, so please do not rely solely on them, instead come here for the specifications. It seems people giving the ratings here are inconsistent, as can be seen in many cases. For instance, have a look at the Samsung S24 versus iPhone 15PM. Samsung has around 10-11 things superior to iPhone, while the iPhone has only one advantage yet it still gets rated higher by 2 points. That does not make much sense. It appears to be pure randomness.

Early benchmark are done by reviewers and they usually done in air conditioned room and others uses some kind off phone coolers. Then normal people gets their hands on their devices and try the benchmark without the phone coolers and outside an AC room which drives the benchmark scores average.
