The Samsung Galaxy S26 series is coming out soon. This series will have the Galaxy S26, Galaxy S26+ and Galaxy S26 Ultra. These phones were just listed in the European Product Registry for Energy Labelling database. This database has information about how much energy devices use. The listing shows how big the batteries are and how long they will last.

1. What is the European Product Registry for Energy Labelling database and why is it important

The European Product Registry for Energy Labelling database is a website that keeps track of how energy devices use. This includes phones, appliances and TVs. Companies have to give information about their devices like how big the battery is and how long it lasts. This information is important because it helps people know what to expect from their devices.

Companies have to give information like:

How big the battery is

How long the battery lasts

How energy the device uses

How easy it is to fix the device

How good the device is for the environment

Because this information is official companies cannot make it up. This makes the database more reliable than rumors or leaks.

The database just listed some phones, like the Galaxy S26 Ultra, Galaxy S26+ and Galaxy S26. These listings show how big the batteries are and how long they will last.

2. The Galaxy S26 Ultras battery

The database says the Galaxy S26 Ultra has a battery that’s 4,855 mAh.. Samsung will say it is 5,000 mAh. This is because companies usually give two numbers for battery size. The first number is the size and the second number is a bigger number that they use for marketing. The Galaxy S26 Ultras battery will last for 1,200 cycles before it starts to get weaker. This is very good compared to phones.

3. The Galaxy S26+s battery

The database says the Galaxy S26+ has a battery that’s 4,755 mAh. Samsung will probably say it is 4,800 mAh. The battery will last for 1,200 cycles before it starts to get weaker. This is a little smaller than the battery in the Galaxy S25+. It is not a big difference.

4. The Galaxy S26s battery

The database does not have information about the Galaxy S26s battery yet.. Other sources say it will have a battery that is around 4,300 mAh. This is a little bigger than the battery in the Galaxy S25.

5. Comparison of the Galaxy S26 series batteries

Model Battery size Change from year

Galaxy S26 ~4,300 mAh +300 mAh

Galaxy S26+ 4,755 mAh same

Galaxy S26 Ultra 4,855 mAh same

6. Comparison with the Galaxy S25 series

The Galaxy S25 series had batteries that were:

S25: 4,000 mAh

S25+: 4,900 mAh

S25 Ultra: 5,000 mAh

The new phones do not have bigger batteries.. They will have better efficiency, which means they will last longer.

7. Battery lifespan

The database says the Galaxy S26 series batteries will last for 1,200 cycles before they start to get weaker. This is very good compared to phones. Phones batteries only last for 500-800 cycles.

8. Charging speed

The Galaxy S26 series will have faster charging speeds. The Galaxy S26 will have 25W wired charging and 15W wireless charging. The Galaxy S26+ will have 45W wired charging and 15W wireless charging. The Galaxy S26 Ultra will have faster charging speeds, possibly up to 60W wired charging.

9. Why Samsung did not make the batteries bigger

There are a reasons why Samsung did not make the batteries bigger. One reason is that it would make the phones thicker and heavier. Another reason is that the new processors are more efficient which means they use energy. This means the phones can last longer without needing batteries.

10. What this means for users

The Galaxy S26 series will have battery life. The Galaxy S26 will last for 7-9 hours of screen time. The Galaxy S26+ will last for 8-10 hours of screen time. The Galaxy S26 Ultra will last for 9-12 hours of screen time.

11. Impact on types of users

Heavy users will like the Galaxy S26 Ultra because it has the best battery life. Average users will like any of the Galaxy S26 series because they will all last for a day. Light users will like any of the Galaxy S26 series because they will all last for than a day.

12. Sustainability and EU energy regulations

The database also shows that Samsung is following EU sustainability regulations. This means the phones will have battery lifespan and be more environmentally friendly.

13. Samsungs strategy

Samsungs strategy is to focus on efficiency and performance of making the batteries bigger. This is because battery technology is not improving fast as processor efficiency. Efficiency gains often provide results than larger batteries.

14. Comparison with phones

Other flagship phones have similar battery sizes. The Apple iPhone Pro Max has a battery that’s around 4,400-4,500 mAh. The Google Pixel Pro has a battery that’s around 5,000 mAh. Chinese flagship phones have batteries that’re around 5,000-6,000 mAh.

15. Charging cycles and long-term durability

A battery cycle is when you charge your phone from 0-100%. The Galaxy S26 series batteries will last for 1,200 cycles before they start to get weaker. This is very good compared to phones.

16. Why rated capacity matters

Rated capacity is the size of the battery. Marketed capacity is the size that companies use for marketing. Rated capacity is more important because it is the size of the battery.

17. Expected launch timeline

The Galaxy S26 series is expected to launch in February 2026. It will be available globally after.

18. Overall evaluation

The Galaxy S26 series has some upgrades, like better durability and faster charging.. It also has some drawbacks, like the Ultras battery not being bigger. Overall the Galaxy S26 series will have battery life and be more efficient, than previous models.
