After the recent 4.0 update in my nothing phone 3a the battery is started draining fast from before now most of the times I need to charge it 2 times a day apart from before where I used to charge it a single time before the day and the battery used to last longer with usage

Does anyone else have a new sound after the update for certain notifications and on the hour, which sounds like water pouring? Does anyone know how to turn it off?

I just upgraded to Nothing OS 4.

When trying to search for apps with the app drawer, like I have done problem-free for years on Android, I am now promoted to agree to.more AI terms of use etc.

I just want to search. I want to opt out. I searched online and there seems to be no way to opt out of this feature.

Consider this feedback..I’m disappointed that a previously functional phone has now lost its search functionality unless I submit to having AI shoehorned into yet another facet of my life.

Please patch this garbage and provide the option for a regular search. Pretty sure this is the first and last Nothing phone I will own, if this is the kind of stunt the company pulls.

Why does the battery only last a day since I installed 4.0 on my 3APRO? Before I could use the phone for 48 hours, now I can’t anymore.

Kind of crazy they’ve not even acknowledged any of the issues we have.

Have Nothing already gone on Christmas holiday and we’ll get fixed in the New Year if lucky?

So after the update I feel and notice slight lag. It’s not that smoother as it used to be, later it was butter smooth. After the update there are slight lags here are there, even while using apps. So I bring this to your notice and expect an action from your part. Because that’s what you are known for,ie, listening to your community.
