Apple’s 2026 flagship, iPhone 18 Pro Max, could finally borrow a trick from Android’s playbook, while battery capacities get a serious bump across the Pro lineup.
Apple’s iPhone 17 series barely hit shelves before the rumour mill shifted focus to next year’s model — and the early whispers are intriguing. According to leaker @UniverseIce on Weibo, the iPhone 18 Pro Max may introduce a variable aperture on its main 48MP camera, a first for any iPhone. Meanwhile, both Pro models are tipped to get noticeably larger batteries.

What Is a Variable Aperture, and Why Does It Matter?
A fixed-aperture lens lets in a set amount of light, no matter the scene. A variable aperture, by contrast, physically adjusts — opening wider in dim environments to pull in more light, and narrowing in bright daylight to avoid blown-out highlights. Samsung experimented with this on the Galaxy S9 years ago, and now Apple appears ready to give it a modern spin on the iPhone 18 Pro Max, reportedly improving both low-light shots and controlled daylight exposure.
The catch? The standard iPhone 18 Pro is expected to stick with a fixed aperture, likely because there simply isn’t enough room inside its smaller chassis for the mechanism.
Rumoured iPhone 18 Pro vs Pro Max Specs
| Feature | iPhone 18 Pro | iPhone 18 Pro Max |
|---|---|---|
| Main camera | 48MP, fixed aperture | 48MP, variable aperture |
| Battery capacity | ~4,288mAh | ~5,567mAh |
| Camera advantage | Compact, space-constrained | Adaptive light control |
For context on how far Apple’s camera hardware has come, it’s worth revisiting the official specs for the iPhone 17 Pro on Apple’s own site — the baseline this next generation will need to beat.
Bigger Batteries for Both Models
Battery life has long been an iPhone Pro complaint, and this year’s leak suggests Apple is listening. A 5,567mAh cell on the Pro Max would mark a meaningful jump over recent generations, while the standard Pro’s 4,288mAh pack still represents solid, if less dramatic, growth. Larger batteries typically mean either genuinely longer screen-on time or headroom for more power-hungry features — like, potentially, that variable aperture motor itself.
It’s a pattern TechnoSports has tracked closely; our recent breakdown of the Apple-Intel modem deal hinted at Apple tightening internal hardware integration across the board, and battery efficiency is often where those gains show up first.
A Grain of Salt
It’s worth remembering these are early, unverified leaks — sourced from a single Weibo post months ahead of any official Apple event. Camera and battery specs are among the most volatile details in the rumour cycle, often changing multiple times before launch. If you’re tracking the Pro Max’s camera evolution specifically, our deep dive on iPhone 18 rumours rounds up everything reported so far.
Bottom Line
If accurate, the iPhone 18 Pro Max could become Apple’s most photography-capable iPhone yet, pairing adaptive light control with a much larger battery. For Indian buyers, that combination — assuming Apple’s usual premium pricing holds — would likely position the Pro Max well above ₹1,60,000 at launch. Until Apple confirms anything, treat these numbers as a promising, but unproven, preview.
