Soldato
The OnePlus 7T Pro had a c.4000mAh battery, yet the 8 Pro in more or less the exact same body, fitted a 4500mAh battery inside, along with wireless charging and waterproofing. The space for that extra 500mAh came from quality engineering, a thing which Apple has plenty of, were they willing to invest resources to fit in a larger battery. But that's by the by. The SE is the phone that it is and it's a solid product. Just seems like there're a lot of people saying it's better than it is and looking to excuse the shortcomings (like the small battery).
Is there a higher capacity battery in the same size available to Apple to use?
