Deep I said that Facebook and Instagram are poorly designed apps. They use lots of battery for just caching and other things that I can’t justify. You install and use what you want on your phone. I don’t care. But you can’t blame Nothing for slow charging if you are using the hotspot on your phone while charging. That’s irrational. Charging while using a highly battery dependant and heat generating service like the 5G hotspot will put extra strain on the battery and cause it to heat up too much. Heat kills batteries. That’s simple.
I replied to your post because I see too many people in India complaining about chargers and fast charging issues. Your hot weather is very hard on phones/chargers. If you don’t take some extra precautions, you’ll never achieve fast charging with no matter what charger used.
If you take a look at the community you will see that almost nobody in Europe has the same issues you describe.
