Is India heading for a recession or is it the millennial being rational?

There is a slowdown in the automobile sector and the sales did not boost up during the festival season 2019. Even with the government providing stimulus, the car sales didn't pick up.
There is another news about " sells Rs 750 cr worth of premium smartphones; Flipkart sees 2X growth on day 1" (source). Well that is a whopping 750 crore just for the premium smartphone by one seller in one day. And the total sales would be very much higher this festive season.
So, can we consider the slow down in automobile sector as a sign of an economic slowdown?

iOS 13.1 heats up iPhone

The iOS 13.1 was released recently and using the iPhone for a while makes it build temperature to the  area near the camera. This is the area where the microprocessor A10 chip is located.
So while it means the processor is working hard doing regular jobs, it is noted that the phone is heating up when the dark mode is enabled.
Using the phone with normal mode doesn’t appear to heat it too much.
I am monitoring the issue and will post an update soon.

After each update, most of the apps needs to be configured on first use. So, immediately after the update the apps will take more processing power to configure. After that things will return to normal.

The impact of LED bulbs on our nature

L.E.D bulbs are unquestionably a revolutionary product that can save electricity compared to the incandescent bulbs. The LED bulbs have long life compared to their incandescent counter parts and also consume less electricity.
The LED bulbs that are available from stores have a life of approximately 5 years on 8 hours of daily use and the companies give 1 or 2 years replacement guarantee. Now comes the problem. The incandescent bulbs have zero percent plastic, but LEDs are almost completely made of plastic. When they expire they are also contributing to the landfill and will create big problems. They have electronic components that are also dangerous when damaged.
So, when touting LEDs as a big saver, the companies should also have the responsibility to take back the expired ones and recycle properly instead of going to land fill.
The big benefit is that most LEDs may have only one or two components damaged. So, they can replace the component on very low cost and sell the refurbished ones.
Light Emitting Diodes theoretically have life expectancy of 50,000 hours and it is almost 12 years on 8 hours of daily use. Also, the light output also decrease in course of time. This is mainly because of the failure of the components of the bulb and not the LED itself.
In India, we urgently need a good framework for gathering and properly recycling and disposing electronic waste otherwise this will be another danger in near future.
