While competitors race to build the thinnest foldable phones, Apple is reportedly taking a different path: prioritizing raw power. New leaks suggest the 'iPhone Fold,' potentially arriving in late 2026, will feature a massive 5,400+ mAh split-cell battery—the largest ever seen in an iPhone. This strategy aims to solve the 'battery anxiety' plaguing current foldables, even if it means a slightly heavier, ultra-premium device.
<p>For years, the rumor mill has churned with speculation about an Apple foldable phone. As consensus builds around a potential release in late 2026 alongside the iPhone 18 lineup, recent reports suggest Apple is adopting a surprising strategy for the device's power source. While many competitors prioritize ultra-thin designs, rumors indicate Apple is preparing to equip its "iPhone Fold" with a massive battery, potentially the largest ever seen in an iPhone.</p><p>Here is a look at the current landscape of iPhone foldable rumors, with a specific focus on battery technology and capacity.</p><h3>Bucking the Trend: Prioritizing Power Over Thinness</h3><p>The primary challenge with foldable smartphone design is internal real estate; the hinge mechanism consumes valuable space that is usually reserved for battery cells in standard "slab" phones. Consequently, many existing foldable devices feature smaller batteries than their non-folding flagship counterparts.</p><p>Reports from late 2025 and early 2026 suggest Apple is taking the opposite approach. Rather than sacrificing longevity for the thinnest possible profile, Apple is reportedly prioritizing a massive battery, even if it results in additional weight.</p><p>Supply chain leaks suggest Apple is testing a battery capacity significantly larger than its current top-tier models, with rumors pointing to a range between <strong>5,400 mAh and 5,800 mAh</strong>. If accurate, this would be the largest battery capacity ever included in an iPhone.</p><p>To put this in perspective within the current (early 2026) landscape, this rumored capacity exceeds the current iPhone 17 Pro Max flagship (~5,088 mAh) and is significantly larger than competitors like the Google Pixel 9 Pro Fold (4,650 mAh) and the Samsung Galaxy Z Fold 6 (4,400 mAh).</p><h3>The Technology Behind the Giant Battery</h3><p>To achieve this capacity within a folding form factor, Apple is reportedly utilizing advanced battery technologies and clever engineering:</
