IPHONE 18 PRO MAX'S NEW BATTERY GAINS REVEALED BY LEAKER

Summary from the TLDR Design newsletter

Leaks suggest Apple plans to extend its battery-life lead with the iPhone 18 Pro Max, boosting capacity to around 5000 mAh (SIM) or nearly 5200 mAh (eSIM), up from the already class-leading iPhone 17 Pro Max. Combined with the more power-efficient A20 Pro chip and a newer modem, Apple appears set to deliver even longer real-world battery life despite only modest capacity gains.
