Same here. iPhone 6S + and the battery drains in less than an hour from 100% to about 15%, even if I’m just talking on it. And this is still after I did all they suggested, like closing down background apps, etc. Also, it takes forever to charge back up again! Took a few hours to get back to a full charge from that low. I just got this phone a couple months ago bc the screen cracked on my other one, but I ended up going back to that one b/c it didn’t have 14 on it. Rather have a cracked screen than a dead phone. Apple needs to get on this fix, and not just use it as a way to push their customers into buying newer (and IMO ridiculously overpriced) phones.
