Will my apple iPhone 8 plus still work with the new update iOS 13.5.1

Yes. The iPhone 8+ is compatible with the iOS 13.5.1 update.

Yes it will still work but there are bugs. I updated my iPhone 8+ to iOS 13.5.1 and now I am having problems with my battery running low faster. Also, The mail icon on my home screen keep showing 24 new emails when there are none. All 4 of my email accounts show no new emails except my iCloud account it keep showing 1 unread email when there are none. It continuously shows checking for mail. Perhaps that is the cause of the battery drain. I also experience dropped connection to my wifi. I wish I had waited for these bugs to be fixed.

I also "upgraded" my iPhone 8 to 1OS 13.5.1. And having my battery run low way fast. Doing a bit of research indicates this is happening to every one. My take is Apple wants to get rid of 8's and have all us suckers get a new iPhone. Not gonna happen. Been a loyal Apple supporter for 20 plus years, but when they do stuff like this it starts me to look around for alternatives.

Can you please help me how can I replace my default message app an iPhone 8 Plus? What can I get to replace it on iOS 13.51
