So I have installed iOS 13, clean install without restoring any backup. I have only transferred chat log for my WeChat history.
I understand the first day the iPhone could do some indexing or other stuff. So I give it a pass for the first day. But past couple days after install iOS 13, I have seen worse battery life than previous iOS 12.4.1.
My iPhone 7 (with 100% battery health, got the replacement battery a month ago) was fully charged and shutdown before I went to bad. Woke up around 8 and it is already below 70% around 9:50. I watched couple videos on YouTube while eating breakfast and streamed few songs while I am driving to work.
With my usage pattern, iOS 12 would stayed around 90%.
