Samsung Galaxy S26 Ultra vs S25 Ultra: Is an Upgrade Worth It?

High volatility is likely to continue until the end of May. The question of whether or not to upgrade is always a dilemma for Galaxy S25 Series users. The short answer depends on how often you use the night camera, create videos, and how much you take advantage of AI features on your smartphone. Here is a complete breakdown.

The most fundamental change is in the main camera aperture: from f/1.7 in the S25 Series to f/1.4 in the S26 Series. This is not a software update: it is a physical change to the lens that directly impacts the ability to capture up to 47% more light.

For users who frequently take photos in low-light conditions, this is a significant improvement.

Horizontal Lock is not available in the S25 Series or the S24 Series. This feature combines the gyroscope, accelerometer, and OIS to automatically keep the video horizon level, even in extreme motion.

For content creators or anyone who frequently records videos while walking, this is a strong reason to upgrade.

Some of the Galaxy AI features in the S26 Series are exclusive and will not be available on the S25 Series through software updates.

Super Fast Charging 3.0 on the S26 Ultra can charge up to 75% in 30 minutes, supported by AI-based power consumption optimization that keeps the device performing responsively throughout the day.

During the period of 1-31 May 2026, an exclusive promotion is available with total benefits of up to IDR 3.9 million: including cashback of up to IDR 3.5 million, installments starting from IDR 600 thousand per month, and 0% interest and 0% down payment. (Z-10)
