Choose your time wisely.

Why You Should Completely Wipe Your Phone Every Few Months

Once every few months, I take my iPhone and go to Settings -> General -> Reset -> Erase All Content and Settings. I skip the offer to use a backup, or transfer data, and build from the factory settings. My friends think I’m masochistic. But hear me out.

Clearing out old apps or files, even if it’s just to re-download them, will help almost any device. But deleting is tedious. The trick is to do it all at once, with a clean wipe.

Your vital stuff will still be there. Modern cloud systems, as long as you have your password, will keep the stuff most of us really care about—your SIM card is your phone number, and as long as you have iCloud or Google Photos, copies of your photos and videos are safely stashed in a data centre.

Sure, the performance benefits might not be obvious. So if your phone’s fine, why bother? Because you create an opportunity to resist the temptation of tech maximalism. If your
day has ever felt overloaded with dings and scrolling, a clean phone helps you distinguish what’s useful from what’s just novel.

I start by turning off almost all notifications. I try to go at least a week without downloading Instagram or Reddit. And last round, I fully broke up with those language learning apps, the software equivalent of the jeans I refuse to donate because, someday, I’ll lose that weight and wear them again. Just focus on stuff that’s really useful, right now.

Years of testing consumer tech has made me appreciate this one Seinfeld scene. Jerry and George are trying to write a script. After discussing pen choice, Jerry halts further attempts at procrastination: “It may seem outwardly that the pen and the paper and the chair play a large role. But they’re all somewhat incidental to the actual using of the brain.”

For anyone whose phone, like mine, distracts you from the actual using of the brain, hopefully, this approach will help you turn that device back into what it is: a tool.

D.I.Y. I.T.: How To Reset Your Phone (A Step-By-Step Guide)

1. Save a new, full backup of your device to iCloud, your Google account, wherever. This is your safety net.

2. If possible, open a computer, or any secondary device that you can use to sign in to your email accounts. This is so you can respond to security prompts or emails from Apple or Google and say, “Yeah, that’s me,” when you re-log into everything.

3. Handwrite (seriously) the apps you can’t function without. For me, that’s stuff like
Fantastical, Slack, and Outlook. Only the essentials.

4. Write down the passwords for your most vital memberships. If you forget one, most are (unnervingly) simple to recover, so focus on ones that could be annoying to reclaim in a hurry. For me, that’s Amazon, Spotify, my Google accounts, and Lyft.

5. Jump off the cliff. Settings -> General -> Reset/Erase All Content and Settings.

6. Skip the prompt that asks if you want to restore it from a backup, and choose to set it up as new. Add more apps only when you absolutely need them.

Choose your mobile wisely by not going for megapixel war !
Check camera image in low light conditions and screen display both.
This can give better idea to spend on which Mobile model etc.


Consumers not given the real picture in megapixel war? ...

One of the big wars being fought by smartphone manufacturers is the megapixel count of cameras.

RAM has become a specification to fight for and companies are now cramming in more megapixels to try and grab the attention of consumers. And this trick is working too. Grand advertising of smartphone cameras with high megapixels count means that the unsuspecting buyer will fall for the trick.

The common perception is that more megapixels will result in better quality photographs. Unfortunately, it is not that simple, and a quality photograph depends on several factors.

It is important to understand why we need a lot of megapixels. If a picture shot on a smartphone is going to be printed on a huge poster, a high megapixel camera ensures that the photo does not become grainy and distorted after printing. But for use on webpages or sharing on social media, a figure of 12 megapixels will do just fine.

Megapixels help in getting a quality picture, but only to an extent. The most important part of a camera is the sensor. The sensor is the part that records the information (or light) coming in through the lens and needs to be of high quality in order to capture a good image. So, if the smartphone camera is 48 megapixels but the sensor is of moderate quality, the results are not going to be as good as a 48 megapixel camera with a quality sensor from, say, Sony or Samsung.

There is more to the sensor than mere quality. A digital single-lens reflex (DSLR) camera that has just about 12 megapixels will shoot far better pictures than a 48 megapixel smartphone camera. The reason is the size of the sensor. A full-frame DSLR sensor is 36 x 24 mm, while a smartphone camera sensor is about as large as the fingertip. With this size difference, there is no way that a smartphone can achieve the quality of a DSLR. If manufacturers wanted to put in a larger sensor, the size of the phone would also increase, and this is not something that they would want to do.

As large sensors cannot be accommodated in small smartphone enclosures, companies use a technique called pixel binning to try and improve picture quality. Simply put, information collected from four pixels is combined to make one large pixel. So, if a company claims a figure of 48 megapixels, it is really only a 12 megapixel camera.

Pixel binning is used to improve low-light photography.

So, when a manufacturer puts down 48 megapixels on the specification sheet, the consumer is misled. Most consumers would not bother to go into the nitty-gritties of smartphone camera technology. This is only helping companies sell more and benefit from this megapixel war.

Also, manufacturers use what is called software interpolation to boost megapixels and achieve quality.

Even when a high-resolution picture is shot on a good quality smartphone camera, a lot of information is lost because social media sites often compress images while uploading. So, the quality of the picture on the smartphone will be better than the one uploaded on social media.

Ultimately, the technique companies use to boost the megapixel count or improve picture quality is irrelevant. The point is that the consumer is not getting to know the real picture.

Consumers not given the real picture in megapixel war?
