Why should I buy an iPhone?

My answer to Why should I buy an iPhone?

Answer by Allen He:

Let me start by saying that I like Android phones. I love the variety of hardware and myriad software customization options. The Galaxy S7 and S7 Edge are especially compelling for those who want thebest phone camera. But when most friends and family ask me what phone to buy, I tend to recommend the iPhone over Android.

Notice that I didn't say "iOS over Android." The reason to go the Apple route isn't just the platform; it's how the software and hardware complement each other. Live Photos on theiPhone 6s and 6s Plus, as well as the new iPhone SE, is a perfect example. The iPhone also works seamlessly with other Apple gadgets, including Macs and the Apple Watch — there's an ecosystem factor. Here are 10 reasons why the iPhone beats Android.

1. Better Hardware and Software Integration

The iPhone 6s and 6s Plus introduce a new feature that no Android phone maker could copy. The 3D Touch display is smart enough to sense pressure, allowing you to take quick actions from the home screen just by long pressing on an app icon. Or you could peek at that email just by lightly tapping on it in your inbox. Sure, Android phones have offered haptic feedback for ages, but the Taptic engine in the new iPhones promises to be super efficient.


2. Live Photos

The iPhone consistently produces pleasing photos with accurate color, generation after generation. And the iPhone 6s and 6s Plus up the ante with a sharper 12-megapixel camera with 4K video capture. Just as important as the bump in resolution is Apple's homegrown image signal processor, which delivers realistic colors. This same camera is now available on the iPhone SE.

The most compelling and unique iPhone camera feature is Live Photos, which captures video and audio during and just before and after your shot. You animate the image during playback by just long pressing on the screen. Other Android phones have offered similar features, such as HTC's Zoe, but Live Photos is easier to use. Plus, both Facebook and Tumblr support Live Photos, so you can share them with your friends.

3. It's the Easiest Phone to Use

Despite all the promises by Android phone makers to streamline their skins, the iPhone remains the easiest phone to use by far. There's no separate app drawer for your apps and no annoying overlay to get in the way. Some may lament the lack of change in the look and feel of iOS over the years, but I consider it a plus that it works pretty much the same as it did way back in 2007. Pick it up, turn it on, touch the app to open.

Of course, Apple has folded in enhancements over the years, such as Siri and Control Center (though I think the Today Screen still isn't useful enough), but the iPhone still has zero learning curve. With iOS 9, Apple is playing catch-up in some ways, especially by putting transit into in Maps, but the proactive assistance features, improved search and smarter Siri add up to a better overall user experience than Android. We could do without the new News app, though.

4. OS Updates When You Want Them

This is going to hurt a little, Android fanbois. Five months after Android Marshmallow debuted (the latest version of Google's software), it was installed on a whopping 2.3 percent of devices. Contrast that with the 80 percent of active Apple devices running the latest iOS 9 software as of March 2016.

The problem is this: with the exception of pure Android phones like the Nexus, the Samsungs, LGs and HTCs of the world have to jump through more hoops to bring you the latest version of Google's OS, including carrier certification. Plus, phone makers typically drag their feet on updating older phones, so as to encourage folks to upgrade. All iPhone owners can update to the latest version of iOS on day 1 (or close to, depending on Apple's servers). This dynamic isn't going to change anytime soon.

5. The Best Apps First

Now that both iOS and Android have more than 1 million apps in their stores, the arms race is over, right? Not really. The iPhone is still favored by developers as the launch platform of choice for the hottest new apps.

The Google Play store is like the Netflix of app stores; it gets the hits, but usually after they see their first run on iOS. For instance, it took two years for Instagram to debut on Android after it launched for the iPhone. Other apps have taken only months to jump for iOS to Android, such as the Meerkat and Periscope video streaming apps and the highly rated Vainglory game. But the message is clear. If you don't want to be treated like a second-class app citizen, the iPhone is still the king.

6. No Bloatware!

It's not a good sign for prospective Android phone buyers that some of the most popular articles we do are bloatware-removal guides. Samsung and others have gotten better at minimizing the pain for users by lumping all carrier bloatware into a single folder, but it's still just crap taking up space on your phone.

You won't find a single piece of carrier software pre-loaded on an iPhone, making for a clean out-of-box experience. Now, Apple does include some apps you might not want or need, like Apple Watch, but it has much more restraint than other manufacturers when it comes to bundling its own stuff.

7. Works beautifully with Macs

If you haven't tried a Mac in a while, you might be surprised to know just how well iPhones work with them. For instance, with the Continuity feature in OS X, you can use your MacBook to send and receive text messages and even receive and place calls. All you have to do is keep your iPhone nearby.

I find the Handoff feature a little less useful, but some may like that they can do things such as start an email on their Mac and then pick up where they left off on their iPhone — or vice versa. Thanks to iCloud keeping everything in sync, you'll also have easy access to the photos you take on your iPhone from your Mac, as well as any notes or documents you create.

8. Apple Pay

Between Android Pay and Samsung Pay, Apple has plenty of rivals, but right now Apple Pay is the most popular method for making mobile payments. It’s also dead-simple to use. All you have to do to use Apple Pay is bring your iPhone close to the supported payment terminal at the checkout counter, then press your finger on your phone's Touch ID sensor.

Apple Pay is getting better with iOS 9, too, which adds reward cards from the likes of Dunkin' Donuts, Panera and Walgreens. Store-issued credit card support is available now, too, with BJ’s Wholesale Club, Kohl’s and JCPenney on board so far. All of the above will be stored in the new Apple Wallet app.

Samsung Pay can be used in more physical locations, but with reports that Apple Pay will be available to mobile websites later this year, Apple will likely extend its mobile payments lead.

9. Family Sharing

An Apple family that plays together, saves together. With Family Sharing on the iPhone, mom, dad and the kids can share purchases from the App Store, iTunes and iBooks with up to six people. You can still keep your own iTunes accounts, too. When Junior wants to make a purchase, you'll receive an alert via the "Ask to Buy" feature, so you can keep better tabs on what he's downloading and also prevent bill shock.

Other Family Sharing features include shared photo albums, a shared calendar and the ability to see where your kids are on a map at any time. Google doesn't offer easy family sharing on Android devices.

10. Best Support and Help

When you have a problem with your Android phone, you can try online forums or calling your carrier. But with the iPhone, you can tap into a vast database of useful help articles on Apple's website, get help via live chat, or you can schedule an appointment at an Apple Store Genius Bar. Google doesn't have this kind of direct relationship with its customers. With Android, you're on your own.

Should I buy Xiaomi Redmi Note 3? Why?

My answer to Should I buy Xiaomi Redmi Note 3? Why?

Answer by Allen He:

Xiaomi Redmi Note 3 short review: An awesome budget smartphone

These days, flagships are defined in two ways — one, where companies pack in every single feature that their R&D guys create, into one single device, making it the most expensive item in their catalogue. This is consistent with the original meaning of flagship – the ship which flew the pennant of the senior most officer in the squadron and which was invariably their most powerful battle ship in that engagement.

The second, more recent take on the terms seems to be — the most compellingly priced combo of price and performance with features and design that make sense to the target consumer. This is the value or paisa vasool flagship.

How ironical that it takes a 'foreign' company like Xiaomi to understand the pulse of this country's buying behaviour to take a phone from its global line-up and customize it to Indian taste and price point. While the Mi 4i of last year was somewhat of a teaser in this direction, the Redmi Note 3 released last week, is a clear indication that here's a company that takes India seriously.

This is the first device in India that ships with the latest Snapdragon 650 processor under the hood. Xiaomi claims that this processor has excelled at every single benchmark test in the world. Having used the device for a while now, we can not vouch for the fact that it does not have the heating issues that other Snapdragon processors have become infamous for, nor does it have apps hanging in the middles of a session. With hand-picked features like a dual-channel memory (The memory has two separate units), a dual image signal processor (for faster focus and better image quality) and in-built fast charge capabilities (50% in 1 hour, and 3 hours for full charge), the Redmi Note 3 has enough brute force to power it.

But what does this translate to, for the everyday smart phone user? The simple answer is: a handful of features that are cleverly thought out. Take the fingerprint sensor for instance. Xiaomi claims that the Redmi Note 3 has the most ergonomically designed fingerprint sensor ever. The 360 degrees recognition sensor can store up to 5 fingerprint profiles, and lets you programme your fingerprints to fire up apps and websites — even third-party apps. With the LastPass function, the device is the first of its kind that allows you to use your fingerprints for opening Net Banking sites, movie ticket and flight booking sites, even e-commerce gateways.

The strategically located fingerprint sensor (right below the camera) lets you perform some acrobatics with the device as well. You can, for instance hold it up and take a selfie from its primary camera. The fingerprint sensor also acts like the camera key. If 16 MP selfies interest you, rather than a 5 MP photo with the front camera, you can always indulge yourself with the Note 3. Of course, you might end up looking slightly funny if you were to do this in public. Having taken your selfie, the device has DSLR-level image processing using something called PDAF (Phase Detection Autofocus) for super fast image processing with accurate white balance.

The Redmi Note 3 features two more interesting imaging-related features that make it stand out. Something called Sunlight Display automatically adjusts the text on your screen to ambient light conditions so you can still view fairly light lettering with ease. And, a reading mode ensures that the blue light filter is reduced when you read in the night, making it soothing for your eyes. Xiaomi actually claims that this feature gives you better sleep. The things smart phones do these days!

The Redmi Note 3 is manufactured made in India, and is currently available for online sale on mi.com and Amazon. The 5.5-inch full HD device comes with a 4050 mAh battery, a full metal body and dual 4G SIM slots. It costs Rs 9,999 for the 2GB RAM, 16GB internal storage model and Rs 11,999 for the 3GB RAM and 32GB storage variant.

If this is the trend of flagship devices in 2016, we're all for it!


The Redmi Note 3 is one of the first phones in India to support VoLTE technology. This stands for Voice over LTE and it is exactly what it says: voice calls over a 4G LTE network, rather than the 2G or 3G connections which are usually used. The big advantage of VoLTE is that call quality is superior to 3G or 2G connections. VoLTE has up to three times more voice and data capacity than 3G and up to six times more than 2G GSM. LTE or Long Term Evolution is the jargon for 4G technology.

Tata Consultancy Services recently unveiled a solution to enable mobile providers to VoLTE-enable their networks. Among Indian brands, Reliance Retail has introduced its entry level range of LYF phones with VoLTE technology.

Should I buy Xiaomi Redmi Note 3? Why?

Will charging with a portable power bank damage cellphone’s battery life?

My answer to Will charging with a portable power bank damage cellphone's battery life?

Answer by Allen He:

Powerbank is popular right now as more and more people use them. Previously, when we buy a new mobile phone, we always buy several batteries for the energy storage. With the appearance of power bank, the situation is changed. We only need one battery if we have a power bank on hand.

So is power bank harmful to the PCBA or battery of mobile phone and PCBA? We could talk about it in two aspects.

how do power bank works ?

What is the mechanism of its working?

This power bank can deliver 4.5 Volts with reasonable current to charge the Mobile phone quickly. It can charge the Mobile phone 3-4 times . The Power bank uses a 4.5 V Rechargeable battery that can be charged using the Mobile phone charger or from the USB port.

4.5 V Rechargeable battery is now available with a rating of 1 Ah, 1.5 Ah, 2 Ah etc for less than Rs.100. This battery can be used or use a high efficiency Lithium battery.The Mobile phone battery is 3.6 V so 4.5 V from the Power bank is sufficient for charging. Transistor T1 act as a current regulator during charging the Mobile battery.

1.When we discharge the power bank, we should look at the output voltage whether it is constant current charge and constant voltage charge. The voltage of charging of a mobile phone battery is 4.2V~5.2V. As the output voltage for most power banks are about 5V, so it will be no problem.

2.When we charge the power bank, it will be better if we keep it constant current charge and constant voltage charge. The ordinary standard of charging battery for mobile phone is 5V/500mA~1000mA. And the standard for many old mobile phones are 5V/300~500mA.According to the figure, many power banks could meet the requirement.

3.The conclusion is that if the power bank works with constant current charge and constant voltage charge, the it will be not be harmful to the mobile phone battery and PCBA.

Tips: Protection board, the board is like a computer motherboard, if good motherboard can drive all of the parts very easy in operation and protection of power bank supply board can make the inside of the capacity and safety to achieve the comprehensive, but not good don’t do, there will always be some, in order to pursue interests regardless of the quality of the products businesses, is the market at present most of the use of power bank supply using cobalt acid lithium protection board, power bank supply volume is small and exquisite, made of this material but poor safety performance, resistance to overcharge performance is poor, not suitable for high rate discharge, Poor circuit board, the overcharge protection functions such as missing. Not only for power bank supply, short service life are more likely to cause explosion; So the design of the protective plate must be reasonable and practical.
