Tipster Ice Universe claims the upcoming Galaxy S27 Ultra will weigh 218g and measure 7.9mm thick, marking a 4g increase from the S26 Ultra. This reversal of Samsung's recent weight-reduction trend is likely driven by a larger 5,700mAh battery, though it contradicts earlier rumors of a lighter device.
Samsung’s upcoming Galaxy S27 Ultra is rumored to feature a 5,700mAh battery, a 14% increase over the current model, and an M16 OLED display. A recent reader poll showed that consumers prioritize battery life over display upgrades, with 62% voting for the larger battery. The phone is also expected to adopt a new rectangular camera design similar to the iPhone 17 Pro.
Leaked protective cases for the Samsung Galaxy S27 Ultra and Pro confirm a major redesign featuring a horizontal camera bar, similar to recent Apple iPhones. While the overall layout is confirmed, specific lens placements differ from earlier renders. The S27 Ultra is also expected to feature a significantly larger 5,700mAh battery, a 14% increase over the S26 Ultra, alongside a new M16 OLED display and Snapdragon 8 Elite Extreme Gen 6 chip.
The upcoming Samsung Galaxy S27 series, expected in early 2027, is shaping up to be a significant upgrade. Leaks indicate the new S27 Pro and S27 Ultra will feature larger batteries, with the Ultra potentially reaching 5,700mAh. While rumors suggest LPDDR6 RAM and UFS 5.1 storage, conflicting reports from Qualcomm and Samsung cast doubt on these specs. The Ultra may also drop its 3x telephoto camera in favor of a 5x lens, and the lineup could expand to four models.
Regulatory filings suggest the Galaxy S27 Ultra will use a 5,700mAh battery and the S27 Pro a 5,200mAh cell, a notable jump from the S26’s 5,000mAh. The move signals Samsung’s renewed emphasis on longer-lasting flagship devices after years of conservative battery sizing.
Apple reportedly ships the iPhone 18 Pro Max with a firmware-enforced battery cap below 20Wh to meet shipping rules; the limit is automatically removed when you activate the device, restoring full charging. A manual Prepare to Ship mode can also cap charging at 80% for 14 days for repairs, trade-ins, or gifts, after which normal charging resumes.
Apple’s EU energy labels reveal the iPhone 18 Pro has 4,056 mAh and the iPhone 18 Pro Max 5,391 mAh (up 1.7% and 11.7% vs the 17 series, respectively). The Pro Max shows a larger battery life improvement than the Pro. eSIM-only variants will have a slightly larger battery in several regions to offset the missing SIM tray, but exact eSIM capacities haven’t been confirmed yet; standard SIM-tray models in the UK/Europe retain the regular capacity.
A leak and regulatory data point to the iPhone 18 Pro Max having a notably larger battery than the iPhone 17 Pro Max: about 5,391 mAh in China and 5,567 mAh for the U.S. (vs. 4,823 mAh and 5,088 mAh), implying roughly 10–12% gains, while the smaller iPhone 18 Pro would see smaller increases. Differences stem from non-U.S. models retaining a SIM tray, freeing space for a bigger cell in the eSIM-only U.S. version.
Leaks suggest the Galaxy S27 Pro will have a rated 5,087 mAh battery (roughly 5,200 mAh typical) and the S27 Ultra a rated 5,534 mAh (roughly 5,700 mAh typical), both larger than the S26 Ultra's 5,000 mAh, with hints that Samsung may be adopting silicon-carbon anodes.
Speculation following the Z Fold 8 reveal centers on Samsung’s silicon-carbon battery tech possibly enabling a larger Galaxy S27 battery, with rumors of up to about 5,700 mAh for the S27 Ultra if a ~14% bump is applied; Samsung reportedly remains cautious about Si‑C cell expansion over time, and there’s no official confirmation yet.
New leaks claim Samsung will use Qualcomm's Snapdragon Wear Elite (no Exynos) for the Galaxy Watch 9 and Watch Ultra 2, promising faster charging, improved performance, and on-device AI. Battery upgrades include an 800mAh cell for the Ultra 2, with the Watch 9 rumored to use 325mAh (40mm) or 445mAh (44mm); Bluetooth 6.0, dual-band Wi‑Fi, LTE variants, and titanium for many Ultra 2 units are also noted. A higher launch price is suggested, a point of contention amid competition from Apple Watch.
A Chinese leaker claims Apple’s battery supplier registered two cells totaling about 4,883mAh (roughly 4.8–5.0Ah) for a foldable iPhone, suggesting a dual-cell, book-style design and fueling expectations for an iPhone Ultra launch alongside the iPhone 18 Pro lineup in September; this figure sits near rival foldables and contradicts earlier rumors of even larger packs, leaving the exact capacity still uncertain.
Rumors suggest the iPhone 18 Pro Max will be roughly 2mm thicker and around 240g, driven by a larger 5,500mAh battery (with regional variations in capacity). If true, this would make it Apple’s heaviest iPhone in years, with an aluminum chassis and weight increases attributed to internal changes rather than a switch to heavier materials.
Apple’s iPhone 18 Pro Max is tipped to get its biggest battery boost yet, with US models reportedly packing a 5,567mAh cell (vs. 4,823–5,088mAh on the 17 Pro Max across regions) and Chinese variants around 4,056–4,288mAh. The jump is aided by Apple’s switch to an eSIM-only design in the US, freeing space for a larger pack, and is expected to pair with a next-gen A-series chip and more efficient displays to deliver noticeably longer endurance, narrowing the gap with Android flagships. Launch is anticipated later this year.
A leaker citing regulatory filings suggests the iPhone 18 Pro Max will have a significantly larger battery than the iPhone 17 Pro Max (about 5,391mAh in China and 5,567mAh in the U.S.), with the iPhone 18 Pro showing 4,056mAh (China) and 4,288mAh (U.S.). The numbers are unverified and may be affected by factors like the SIM tray. If confirmed, this could translate to roughly a 10% battery capacity increase and longer life, though actual performance depends on chips, display, and optimizations. The devices are expected to debut in early September, alongside a foldable reportedly named iPhone Ultra.
