Having now lived with the UI 7 update for 3 days I find my experience focusing on a feeling of personal violation and vandalism of my property .

I purchased my A15 G5 two years as it meet all my requirement at a good price point. I was looking for a phone with excellent battery life and the A15's large 5000mA provided over two days use before charging. I also wanted to host my music collection of about 300GB and the external memory card made that easy. I also used Gmaps a lot as I live in a rural location and this work fine. Finally I needed good email and a basic WEB browser.

All pretty basic requirements that the A15 G5 nicely met for two years.

Then came the UI7 "update".

This morning my A15 consumed 20% of its battery in the first two hours of the day doing nothing but reading the morning news and checking email for a total screen time of 30 minutes. Based on yesterday by lunch it will have consumed 50% of its battery mostly sitting on the table unused.

Now if I use Gmaps while out in the car the A15 becomes very hot (even with the screen turned off!) becoming uncomfortable to hold except by the edges. A card charger is now absolutely needed but while Gmaps is active there is not enough extra power left over to also recharge the battery. After using Gmaps I no longer feel safe with such a hot phone in my pocket for fear of burning or fire.

My A15 is warm to the touch all the time now! I measured a temperature rise of 10F over the room temperature with my A15 just sitting unused on the dinner table. It seems this hot device is always just one step away from a fire after the UI7 update and now I find I no longer trust the safety of the product and worry about having it in my house.

So my experience of the UI7 update is one of violation of my security as a person and a vandalism of my property.

And yes yes I have tried all the suggested "fixes" for high battery drain with very little improvement. UI7 is simply a very broken release that should at a minimum be optional for all users.
