IOS 13.2.2

This is my first time posting on this forum/contacting apple.

I'm not sure why various issues of IOS 13 have been fixed with 13.2.2. For me, all issues persist, with some new ones also present:

• background apps being restarted after switching to a different app for as little as 30 secs. I discovered that this can be slightly mitigated by restarting the phone, however once restarted the problem starts to deteriorate, so that within 24h I have no multitasking once again.

• email app starting up with a random open email instead of the mailboxes screen

• phone shutting down randomly with plenty of battery left (happened twice)

• battery depletion erratic (e.g. dropping 20% over 15 min)

• unusually slow charging: battery gets to about 95%, but after another hour of charging only additional 2% is charged. Can't seem to get it to 100% except for overnight.

• The alarm clock and reminders do not sound in earphones - I often set reminders on my phone and came to rely on them, however since ios 13 (or one of its updates was released), if I have my earphones in and the phone in my handbag, no sound comes through the earphones - the phone is ringing away in the bag and often I don't hear it.

• New issue: vibration with incoming email not working probably 80% of the time (I always have my phone on silent so not sure about sound)

• New issue: Google app appears to be seriously affected. Since the update its speed was decreasing steadily (e.g. the time it takes from me clicking to open the app to the search box to come up). It got to the point where it completely froze, without the possibility to search - only blank screen. Restarting the app would not help. I had to delete and reinstall the app twice so far and just now I'm about to do it for the third time.

• New issue: occasionally the flashlight does not react (have to click multiple times, finally works after about 15secs)

Is anyone still experiencing any of these problems after 13.2.2 update?

*This is my 3rd iphone. My contract with Vidafone is over and I am due an upgrade. I always loved how smoothly iphones worked and was swearing would never get a different phone. However the phone I'm now left with is more or less useless and for the first time ever I'm considering getting a Samsung.
