We'll be rolling out even more features for Nothing OS 4.1 in the future, so please stay tuned.

DentistMGJ🇮🇳 i also experienced this… but strange thing is that….. if you charge it in the morning like before 12pm, charging speed will be better… it’ll be around 15-20w…

I don’t charge separately, my phone is plugged in to my laptop… but i did charging test when i recieved 4.1… the results are same… i have 2 nothing cables and 1 portronics cable all are operating at same watts…

When charging in the morning my device full charges in 1 hr 10mins… 👌🏻

There is one guy who downgraded to 2.6… he just posted in this discussion… he’s getting more than 25w ..

Hi everyone, I have cmf 1 and n4.1 I’ve been using this firmware for a month now, and my phone for almost a year. A couple of days ago, my phone started turning off on its own, even though the battery is healthy and there’s no overheating. I don’t know what’s going on. Please help me figure this out, thanks in advance!

I also noticed that the battery indicator, when it charges to 100%, after turning off the charger, stays at the same % for a long time until I reboot the phone so that it shows a normal %

I really hope that the problem is not with the phone, because it worked fine all this time, discharged slowly and everything was fine with it.
