India Challenges China on Smartphones

Buying a new smartphone was a bit of a mission for Deepa Aswani, who works in marketing in Mumbai.


"I am very particular about what phone I buy. I did not want to invest too much," she says.


After two months of deliberation, she chose the OnePlus 10R, which in a sale cost her $400 (£329), a reasonable price for a smartphone, but still a significant sum in any country, and particularly in a developing one like India.


"The idea was to buy a phone which did not make a hole in my pocket and had good features. I am happy with the phone I have purchased," she says.


Ms Aswani's new smartphone was made by a Chinese firm in India - a common arrangement these days.


But as recently as 2014, the majority of phones sold in India would have been imported.


That has all changed in recent years. In 2022 almost all phones sold in India were made there as well, according to the India Cellular and Electronics Association (ICEA).


Many of those phones would have been made by overseas firms with operations in India, like Taiwan's Foxconn or South Korea's Samsung.


But the number of home-grown firms is increasing rapidly.  READ MORE...

Smartphone Radiation

Radiation Emissions of Popular Smartphones
Smartphones have become an integral part of our everyday lives. From work and school to daily tasks, these handheld devices have brought everything into the palm of our hands.

Most people spend 5-6 hours on their phones each day. And, given that our phones emit a tiny amount of radiation, we’re exposing ourselves to radiation for hours each day.

But different phones emit different amounts of radiation.

With the help of data collected by the German Federal Office of Radiation Protection, we visualize the radiation emissions of some popular smartphones in the market today.

Radiation and SAR Values of Smartphones
Smartphones and other mobile devices emit tiny amounts of radiofrequency (RF) radiation. Humans can absorb this radiation when the smartphone is being used or is lying dormant anywhere near their bodies.

The parameter used to measure phone radiation emissions is the Specific Absorption Rate (SAR). It is the unit of measurement that represents the quantity of electromagnetic energy absorbed by the body when using a mobile device.

The Council of the European Union has set radiation standards for cell phones at 2 watts per kilogram, measured over the 10 grams of tissue that is absorbing the most signal.

SAR values are calculated at the ear (speaking on the phone) and at the body (kept in your pocket). For the purposes of this article, we’ve used the former calculations.

Smartphones With the Highest Levels of Radiation Emissions
The Motorola Edge has the highest radiation emission with a SAR value of 1.79 watts of radiation per kilogram. That’s significantly higher than most other smartphone models in the market today and close to the limits set by the EU for cellphones.

Coming in second is the Axon 11 5G by ZTE with 1.59, followed by the OnePlus 6T at a close third with 1.55 W/kg. The Sony Experia AX2 Plus with 1.41 and the Google Pixel 3 XL and 3A XL at 1.39 round out the top five.

Here is a look at the 10 smartphones that emit the highest level of radiation:

Ruining Your Devices

How many smartphones have you dropped and shattered? It’s an awful feeling – seeing it falling to the ground and knowing there’s nothing you can do.

Years ago, I put a tempered glass screen protector on my phone. The best part is when you drop your phone, and the glass gets nicked, you simply remove the protector, and it's good as new. Here’s a link to the brand I have used for years, ESR.

Our devices are big investments. You need to treat your tech well to get your money's worth. Regular maintenance is one way to stay ahead of the game. Tap or click for six checkups to do now to avoid a hefty repair bill later.

Based on calls to my show, emails, and questions posted on my website’s tech support forum, here are five common mistakes that could cost you:

1. You’re charging too much
Do you keep your phone plugged in all the time? Apple says that when your iPhone “remain(s) at full charge for prolonged periods of time, battery health can be affected.”

Android phone manufacturers, including Samsung, say the same. “Do not leave your phone connected to the charger for long periods of time or overnight.” Huawei says, “Keeping your battery level as close to the middle (30% to 70%) as possible can effectively prolong the battery life.”

The official word is to keep your phone charged – but not fully charged. Get in the habit of unplugging your tech after it is fully charged.

2. You wait too long to charge your laptop
Laptop batteries have a finite number of charge-discharge cycles. If you frequently let your battery entirely run out of juice, it affects the charge-discharge cycle and diminishes its intended lifespan.

Your laptop battery can also lose efficiency another way. Let’s say you regularly charge your laptop from 30% to 50%, or about 20% each time you charge it. Well, do that five times and you’ll have completed one battery cycle because you’ve charged your laptop 100% in total.

A good rule of thumb is to keep your battery charged to at least 40% most of the time. Tap or click here to check your laptop’s battery health.

3. You go with the cheapest option
If you lose your charger or a USB cable gets frayed, resist the temptation to buy the cheapest replacement. The few dollars you save on a low-cost substitute may very likely negatively affect your device’s performance.

One-size-fits-all charger and cable makers don’t want you to know that often their products do not have the proper voltage needed to work with your specific device. Why does that matter? Your battery may end up not getting the juice it needs to charge fully. Worse, it may erode the battery’s life.  READ MORE...

Nigerian Scifi

Nigerian Teenagers Are Making Slick Scifi Films With Their Smartphones

Someone should really snap up the rights for a movie about The Critics, a collective of self-taught teenage filmmakers from northwestern Nigeria.

The boys’ dedication, ambition, and no-budget inventiveness calls to mind other filmmaking fanatics, from the sequestered, homeschooled brothers of The Wolfpack to the fictional Sweding specialists of Me and Earl and the Dying Girl and Be Kind, Rewind.

While smartphones and free editing apps have definitely made it easier for aspiring filmmakers to bring their fantasies to fruition, it’s worth noting that The Critics saved for a month to buy the green fabric for their chroma key effects.

Their productions are also plagued with the internet and power outages that are a frequent occurrence in their home base of Kaduna, slowing everything from the rendering process to the Youtube visual effects tutorials that have advanced their craft.

To date they’ve filmed 20 shorts on a smart phone with a smashed screen, mounted to a broken microphone stand that’s found new life as a homemade tripod.

Their simple set up will be coming in for an upgrade, however, now that Nollywood director Kemi Adetiba has brought their efforts to the attention of a much wider audience, who donated $5,800 in a fundraising campaign.  READ MORE...
