When install beta anyone should full well know about impending bugs and issues. That's a risk one takes hence the warning not to try on primary devide. The public beta is so we the public test and give feedback about bugs. No use complaining unless it's the final release.

I took the risk and installed on my SE and use as daily driver. For me Beta 1 for sure terrible battery drain but Beta 2 battery life definitely more stable. IMO the 2 big culprits are WhatsApp and FB that's causing the drain. If WA was more optimized for sure my battery life better. So can't wholly say Beta problem. But WA now very essential esp at my workplace so can't get rid of it.

If I do have a complaint, I feel the new control center is a mess too much packed in one area. The current one on iOS 10 is so much more neater and 'cleaner' like the kind of aesthetics one is used to with Apple. And only now they add a data toggle! In the 10th year.. heck initially there wasn't even an a control centre. Can't remember which iOS it made it's debut. That's my main bug!

iOS better?
