Samsung’s Galaxy S26 series is nearly here, and leaked EU energy labels have surfaced ahead of the official launch, giving prospective buyers a clearer picture of what these phones actually deliver day to day.
The labels, obtained by Ytechb, cover the full S26 lineup and confirm a few things worth knowing before you spend your money.
Battery Life Looks Significantly Better
The most striking data point is battery endurance. In the EU’s standardized test, the Galaxy S26 lasted 51 hours on a 4,175mAh battery, while the S26 Plus and S26 Ultra each hit 55 hours on 4,755mAh and 4,855mAh cells respectively. Those numbers represent a meaningful jump over the S25 series, suggesting Snapdragon’s efficiency improvements are doing real work here, not just padding spec sheets.
All three phones carry an A rating for energy efficiency, which places them among the better performers in their category.
The Battery Longevity Drop Is Hard to Ignore
Here is where things get uncomfortable. The S26 series appears rated for 1,200 charge cycles before dropping to 80% battery health. The S25 series held that same 80% threshold all the way to 2,000 cycles, which was genuinely class-leading.
That is a significant regression on paper, though it is worth treating with some caution. These EU labels have not gone live officially, and pre-release label data occasionally contains errors.
Repairability lands at class C across the board, drop reliability earns an A, and IP68 water resistance is confirmed for the full lineup.
If the battery longevity number holds up after launch, it becomes an important factor for anyone planning to keep their phone beyond the two-year mark.
