I don’t, but there working on all kinds of advanced AR, machine learning and computer assisted photography stuff that is enabled by faster chips. Faster chips also reduce the time it takes to complete tasks. But it’s mostly for show. That being said, if it’s 30% faster and 40% more battery efficient then it’s the best of both worlds. I have a marketing minor and marketing is never actually about what people need but what they want and you present something in a way which makes your product really attractive: fast, sleek, etc. I think Apple has been pushing the enevelope to get us to a point where they can pivot from 5-10W iOS TDPs to 25-40W MBP TDPs and absolutely annihilate Intel and all the competition. As for battery life, I very rarely see my iPhone X below 30% at bedtime and am above 40% more often than not. Even after nearly 7 months where with previous iPhone models I’ve seen it start to slip after six months. So the battery life is really catching up already and seems to be a natural progression. While most people might actually find battery life to be a more useful feature, it’s not a sexy thing to talk about as a primary selling point. You can supplement battery life with portable chargers, topping up throughout the day or leaving it on a wireless pad on your desk. The same can’t be said about making your phone faster—even though 95% of people won’t need it. You see it on MR and elsewhere after every launch—the inevitable benchmark test against a slew of Android phones.
Anyway, considering no real leaks I doubt it’s sooner rather than later. Maybe Apple got a lot better at keeping things under wraps but it will be sometime between September and March with my money on late October/early November, second on early March, third in September at the iPhone event.
