If you own a Galaxy S25 Ultra, upgrading to the Galaxy S26 Ultra in 2026 is worth it mainly if you want faster charging, the new Privacy Display and a brighter camera. For everything else, the S25 Ultra is still a flagship. The S26 Ultra keeps the same 6.9-inch QHD+ screen, 5,000mAh battery and 200MP camera resolution, and the S Pen is unchanged. So the decision comes down to one number: what the upgrade actually costs once you sell your current phone.

What changed from the Galaxy S25 Ultra to the S26 Ultra
Samsung launched the Galaxy S26 series in India in February 2026. On paper the two Ultras look similar, but there are real hardware changes in charging, the display, the camera optics and the processor.
| Feature | Galaxy S25 Ultra | Galaxy S26 Ultra |
|---|---|---|
| Processor | Snapdragon 8 Elite for Galaxy | Snapdragon 8 Elite Gen 5 for Galaxy |
| Display | 6.9-inch QHD+ 120Hz, 8-bit colour | 6.9-inch QHD+ 120Hz, 10-bit colour, Privacy Display |
| Main camera | 200MP, f/1.7 | 200MP, f/1.4 |
| 5x periscope | 50MP, f/3.4 | 50MP, f/2.9 |
| Battery | 5,000mAh | 5,000mAh |
| Wired charging | 45W | 60W |
| Wireless charging | 15W | 25W (Qi 2.2) |
| Frame | Titanium | Armor aluminium |
| Thickness / weight | 8.2mm / 218g | 7.9mm / 214g |
| RAM | 12GB | 12GB (16GB on 1TB model) |
| Software at launch | One UI 7, Android 15 | One UI 8.5, Android 16 |
Charging: the most noticeable everyday upgrade
Wired charging goes from 45W to 60W. Samsung claims the S26 Ultra reaches 75% in 30 minutes, against the 65% it advertised for the S25 Ultra. Wireless charging also rises from 15W to 25W through Qi 2.2. Samsung did not add built-in magnets, so you need a magnetic case for MagSafe-style accessories. Battery capacity stays at 5,000mAh, so battery life depends mostly on how efficient the new chip is.
Privacy Display: new hardware you cannot get on the S25 Ultra
The biggest new feature is Privacy Display. It stops people beside you from reading your screen, which is useful on a crowded metro or in an office. You can switch it on from Quick Settings, set it to turn on for specific apps, or hide only parts of the screen such as notifications. Because it is built into the panel, no software update will bring it to the S25 Ultra. The S26 Ultra's panel also moves from 8-bit to 10-bit colour, and Samsung has added a new anti-reflective coating.
Camera: same megapixels, brighter lenses
Camera resolution and zoom are the same as before: a 200MP main camera, 50MP ultrawide, 50MP 5x periscope and 10MP 3x telephoto. What changed is the aperture. The main lens is now f/1.4 instead of f/1.7, and the periscope is f/2.9 instead of f/3.4. Samsung claims the main lens is 47% brighter and the telephoto 37% brighter, which should help most in low light and indoor shots. Video also gets a horizontal-lock stabilisation mode.
Performance and AI
Early benchmarks on a reference device with the Snapdragon 8 Elite Gen 5 scored 3,832 single-core and 12,208 multi-core in Geekbench. The S25 Ultra scored 3,031 and 9,829. That is a clear jump, but the S25 Ultra is not slow in daily use. On the software side, the S26 Ultra launched with One UI 8.5 and new Galaxy AI features: Bixby can act as an agent that completes tasks for you, Gemini-based app actions can book rides or order food, and Photo Assist lets you edit photos by voice or text. The S25 Ultra has a promise of seven OS updates, so it will keep getting new software for years.
What has not changed
- Same 6.9-inch, 3120 x 1440, 120Hz screen size and resolution
- Same 5,000mAh battery
- Same S Pen, still without Bluetooth Air Actions
- Same 12MP front camera resolution
If none of the changes above matter to you, your S25 Ultra is still an excellent phone. If they do, check what your 256GB Galaxy S25 Ultra is worth today before you buy, because the trade-in value decides most of the upgrade cost.
Galaxy S26 Ultra price in India right now
The S26 Ultra's official price has gone up since launch. On 23 September 2026, Samsung raised S26 series prices in India. The 12GB + 256GB Ultra went from ₹1,39,999 to ₹1,54,999, the 512GB from ₹1,59,999 to ₹1,74,999, and the 16GB + 1TB from ₹1,89,999 to ₹2,14,999.
Festive sales are where the deals are. During the Amazon Great Indian Festival 2026, the S26 Ultra was listed at ₹1,24,999, which is ₹30,000 below the official price, with ₹6,249 cashback on an Amazon Pay ICICI Bank credit card (Digit, 8 October 2026). In the same sale, the Galaxy S25 Ultra 12GB + 256GB was listed at ₹94,999, or ₹84,999 after a ₹10,000 coupon (Digit, 12 October 2026). Sale prices change quickly, so check the live price before you pay.
How much does the upgrade really cost?
Your net upgrade cost is the S26 Ultra price minus what you get for your S25 Ultra. ReUz's sell page shows these indicative prices for a Galaxy S25 Ultra in good working condition (prices updated 21 October 2026):
| Galaxy S25 Ultra variant | ReUz indicative price (good condition) |
|---|---|
| 256GB | ₹71,000 |
| 512GB | ₹73,000 |
| 1TB | ₹77,000 |
Here is a worked example. If you buy the S26 Ultra at the ₹1,24,999 sale price and sell a good-condition 256GB S25 Ultra for ₹71,000, you pay about ₹53,999 for the upgrade, before any bank cashback. Your final price depends on your phone's condition, which is checked at pickup, so get your own instant quote for your exact model.
Keep in mind that resale value is time-sensitive. Each new Galaxy launch pushes older models down, so if you are leaning towards upgrading, selling sooner usually gets you more. Our iPhone and Galaxy resale value guide explains how prices move over a phone's life.
Should you upgrade? A simple checklist
Upgrade to the S26 Ultra if
- You charge often during the day and want 60W wired and 25W wireless charging
- You work on your phone in public and would actually use Privacy Display
- You shoot a lot at night or indoors and want the brighter f/1.4 main lens
- You can get a festive-sale price and a strong resale value for your S25 Ultra
Keep your S25 Ultra if
- You are happy with the battery life and charging speed
- You prefer the titanium frame over aluminium
- You want to avoid spending about ₹50,000 or more for gradual improvements
Coming from an older Galaxy?
If you have a Galaxy S23 Ultra or S24 Ultra, the jump to the S26 Ultra is much bigger: newer software, a much faster chip and better charging. You can sell your Galaxy S24 Ultra or sell your Galaxy S23 Ultra the same way and use the money towards the new phone.
Exchange offer or selling directly?
Amazon and Samsung both offer trade-ins on the S26 Ultra, but an exchange value is usually locked in at checkout and can be reduced after inspection. Selling directly lets you compare buyers, get paid in your account, and still use the bank cashback on your new purchase. Our guide on OLX vs exchange offers vs buyback compares each option in detail. Before you hand over any phone, back up your data, sign out of your Samsung and Google accounts, and remove your SIM and microSD card if you have one.

Frequently asked questions
Is the Galaxy S26 Ultra worth upgrading from the S25 Ultra?

Does the S26 Ultra have a better battery than the S25 Ultra?
The capacity is the same at 5,000mAh. The difference is charging: 60W wired against 45W, and 25W wireless against 15W. Samsung claims 75% in 30 minutes on the S26 Ultra.
Will the S25 Ultra get the Privacy Display through an update?
No. Privacy Display is a hardware feature of the S26 Ultra's panel, so a software update cannot add it to the S25 Ultra.
