Performance and Battery degradation last few months [Zenfone 10]

[BluFox]

I am daily driving the Zenfone 10 for almost 3 years now, and the last month or two I've noticed an abnormal performance and battery degradation - to the point it literally feels artificial.

I've been charging my phone to 90% for two years every two days (to a floor of probably 20% on the second day). Nowadays I do the same charging routine, but over a one day period. This has been happening for 3 months now, not sure why.

I've also noticed that games, namely in emulation (of games that I legaly own a copy of either physically or digitally), where I was getting flawless performance (it is a Snapdragon 8 gen 2 after all), I am now getting 5 to 10 frames per second.

Something is definitively off. I didn't installed any new apps, actually the opposite, I've uninstalled a few. I am always up to date with software updates.

Thanks

It's impossible that you've been using your smartphone for almost 3 years. It's not even 2 years old yet. It was released in the summer of 2023.

Well, good point, I was checking the receipt and I got it in September 2023.

But it doesn't makes the situation better, tbh.

Does anyone else relates to my original post? Or is it just me?

I don't recognize this on my Zenfone 10, I also own it since summer 2023. However I had to send it back 3 times already (broken usb port, broken sim tray and finally broken screen due to water damage, caused by a dent in the corner long time ago from falling). In this last repair it could be that the battery has been replaced but I'm not sure. So I cannot really compare your case with mine. 

However, my previous Zenfone 8 had similar issues. I charged it to 80% for about a year, then I noticed battery life was a lot shorter so I started charging it to 90% and then 100% in the end to make it to the end of the day. 
On my Zenfone 10 I charge it like half of the times to 80% (mostly overnight), but the other times I charge it to 100%, knowing that I stop charging once it reaches 100%. By doing that I only keep the level at 100% for a short time, which is not as bad for the battery as keeping it there for hours. 

Probably more research needs to be done on this but I think it's not bad to go to 100% now and then instead of never going above 80%, to keep the battery "fit".  I also think the charge limit overnight (80% for example) but then doing the last 20% in the morning is not the best for the battery.

Hi  @BluFox 
As user Legith mentioned, it could be the cause of something working in the background, try the solution the user provided, try also checking in the battery app which apps are working extra, if this doesn't work then I would recommend doing a clean install by resetting the phone.
