How to choose a good and perfect Smartphone...
Picking an Operating SystemLearn some basic differences between operating systems.iPhone (aka iOS) is known for its ease of use, security, and clean integration with other Apple products.Android is associated with its integration of Google services, its ability to be customized, and typically a lower cost.If you can, try demoing a device at a store. That will give you a good sense of the interface and feel of each operating system.Determine your price range. iOS phones (iPhones) are typically more expensive than their Android counterparts. Among phone manufacturers, Apple and Samsung are typically among the most expensive (with models ranging from $400-$700 retail), while HTC, LG, and Motorola tend to produce lower cost options (some low end smartphones can be acquired for under $100).Phones are subsidized when purchased along with a phone carrier contract or sometime even "free" upon signing. This usually commits you to a 2-year billing plan for the carrier and includes penalties for early cancellation.Some carriers also charge a monthly ‘device fee’ to make up for little or no upfront cost on your smartphone.Consider the devices and software you already own. If you already own a tablet or computer, you will experience the best level of integration with its services and software by getting a phone with matching developer support (for example, Apple computers and iPads are often cross-compatible with iPhone apps). Nevertheless, note that any phone can connect to, and function with, almost any computer operating system.If you are a heavy MS Office or Google user, you will have the best integration and support using an Android phone (although note that both Microsoft and Google produce their most popular apps for the competing operating system as well).Determine which features suit your needs. Each operating system has some proprietary features, while basic features like email, web browsing, and maps will be available on all systems.iOS/iPhone has exclusive features like Siri, fingerprint scanning, FaceTime chat, and iCloud support.Android has Google Now, homescreen widgets for customization, and allows third party app installation (meaning you can download programs from the internet and install them outside of the Play Store ecosystem). Most Android phones today also have fingerprint sensors, cloud storage for pictures, and support the use of Google Drive for documents and cloud storage.Consider which apps you want to use. Many popular applications (e.g. Google Maps, MS Office, and Apple Music) are offered across all operating systems, however there are some apps (e.g. iMessage, Facetime, and Google Now) that are exclusive to their respective platform. Check the app store associated with each option to make sure the apps you want are accessible (Apple, Google Play).In general, if a popular app is not offered on a competitor's operating system, there is a strong chance that an alternate app exists which is functionally quite similar.Your app purchases are linked with your store account. You will be able to transfer your purchases to any future phones as long as they use the same operating system.Choose an operating system. For most people, the deciding factor will be personal preference. Those looking for a simple interface and a secure system will tend to like iOS-backed iPhones, while those looking for more custom options and lower cost in general will likely prefer Android phones.Choose a Smartphone Model:Pick a carrier. Most carriers will offer a range of phone options across operating systems (no OS is specific to a carrier). Major carriers often subsidize phones or offer different payment plans and contract combinations to reduce the up-front cost of smartphones.Some carriers, like T-Mobile, allow you to forego a contract while paying off the phone as part of your monthly costs. Cancelling your service early will force you to pay the remainder of the phone’s costs at once.Unlocked phones are phones purchased outside of a carrier and thus not linked with a phone service contract. They are more expensive but allow you much more flexibility if you ever need to switch phone carriers.If buying an unlocked phone, make sure to doublecheck that the model is compatible with your specific carrier’s network. Most carriers have a webpage where you can check compatibility with your phone model's ID information, (for instance Verizon, or AT&T).Pick a phone service and data plan that works for you. Phone service carriers will usually offer a wide range of prepaid monthly plan options for phone minutes, texts, and data over the cellular network.You may be able to cut monthly costs by not purchasing a data plan at all, but this means you won't be able to access the internet from your phone if not on wifi.Pick a screen size. Screen size is measured corner to corner diagonally. Ultimately, screen size is a matter of preference. Smaller screen phones may fit better in your pocket and are often cheaper. Larger displays may be preferable if you plan to watch a lot of videos.iPhone offers the “SE” series for compact phones and the “Plus” series for an extra large screen.Android phones come in a wide range of sizes: there are smaller budget models such as Moto G or Galaxy S Mini, higher end models like the Galaxy S or the HTC One series, and oversized models like Galaxy Note or Nexus 6P.Decide how new you want your phone model to be. Newer phones are typically faster and more powerful than their respective older versions but will come at a higher cost. In particular, older model phones will have a more difficult time running modern applications.For the budget-conscious, a good compromise is to wait for a new model of your desired smartphone to become available and to then take advantage of a drop in price of the other models. When a new phone model premieres interest in older models will immediately go down and the price will often change to reflect that.Regardless of your choice, understand that technology moves very quickly and that newer phone models will continue to appear. Eventually every smartphone will seem old or obsolete.Check the storage space. A phone's storage (usually listed in gigabytes or GB) is a measure of how many files (photos, videos, apps) it can store at any one time. Storage space strongly affects the price of the smartphone so consider how much you're likely to need before settling on a phone model.For example, storage space is the only difference between a 16GB iPhone 6 and 32GB iPhone 6,16GB is estimated to hold about 10,000 pictures or 4000 songs -- but keep in mind that your phone storage must also accommodate all your downloaded apps.[2]Some Android phones (but not all) support storage expansion with the purchase of a microSD card. iPhones do not support storage expansion after purchase.Consider camera quality. Although smartphones are known for taking high-quality photos in general, actual picture quality will vary quite a bit between brands and models. The best way to measure camera quality in a phone is to search for sample pictures online taken with that smartphone model or to demo the camera yourself.While manufacturers often advertise a camera's megapixel count, features like ISO, low-light performance, brightness, and noise reduction are equally if not more important to consider.Most modern smartphones come equipped with front and rear-facing cameras and flash, and will support third party add-ons (such as lens attachments).iPhones are well known for their high quality camera hardware/software.Consider phone battery life. Battery technology is improving steadily so newer phones tend to have longer battery life, however your usage habits are what really dictate how long the battery lasts. Talking on the phone, gaming, and using phones outside of wifi range will all drain a battery more quickly.Average smartphone battery life can range anywhere from 8-18 hours.[3]Most flagship Android models will not support replaceable batteries. iPhones do not support replaceable batteries on any model.Some newer Android phones utilize a quick charge technology to help recharge their large batteries faster (e.g. Samsung Galaxy S series or Motorola Droid Turbo series). Manufacturers claim phones with quick charge can achieve 50% charge in about 30 minutes.

Iron Mans Arc Reactor ;)
That phone you carry with you like it was your Iron Man’s Arc Reactor; the one that reassuringly beeps under your pillow as you go to sleep and buzzes you up in the morning with a hundred notifications; How much do you really know about that phone?
