Yes—by the manufacturers’ published capacity figures, vivo’s X Fold6 lists an equivalent 6,900 mAh battery, compared with 5,000 mAh typical capacity for Samsung’s Galaxy S26 Ultra. That is a 1,900 mAh difference, or about 38% more than Samsung’s stated capacity. It does not prove the vivo lasts longer: the figures are not a matched battery-life test.
How the published battery capacities compare
| Phone | Manufacturer-listed capacity | What the figure means |
|---|---|---|
| vivo X Fold6 | 6,900 mAh equivalent typical capacity; 26.09 Wh typical energy | vivo lists two parallel cells: 3,997 mAh and 2,903 mAh, each at 3.78 V, equivalent to one 6,900 mAh battery. vivo Europe specifications |
| Samsung Galaxy S26 Ultra | 5,000 mAh typical capacity | Samsung’s listed typical battery capacity. Samsung Thailand product page |
The 1,900 mAh gap and the approximately 38% comparison are arithmetic based on those manufacturer-published figures, not a separately published measurement. The X Fold6’s 6,900 mAh number is an equivalent-capacity figure for its two-cell arrangement; it is not a claim that either individual cell has that capacity.
Does the bigger number mean longer battery life?
Not necessarily. Milliamp-hours describe charge capacity, not how long a phone lasts in a particular person’s use. Screen size and brightness, processor workload, network conditions, software, and other factors affect energy use. The manufacturer pages cited here do not provide a matched independent endurance test of the X Fold6 and S26 Ultra, so they cannot establish which phone lasts longer in real-world use.
