Smartphones and Power banks – A brief look in them

Smartphones are getting popular across the globe including India. With people relying more and more on mobiles for not just making calls and sending text, but also for various other tasks like taking pictures, making videos, listening songs, watching movies and staying in touch with friends and relatives using social media. Many studies have shown that more than 60 percent of smartphone users spend six hours a day with their mobile. With so much usage they quickly run out of battery, as mobile phone batteries are not designed to last so long. This problem can be overcome either always keep your mobile plugged in or using a power bank.

Power Banks in India

Power banks are storage device that can charged up your mobile phones, iPads and even tablets. They are portable and small enough to be carried in your bag pocket. Nowadays there are many models and types of power banks are available costing anywhere from Rs 500 to Rs 7000. While purchasing power banks, you should always look at the capacity and safety features of the power bank. More the capacity, the more number of times you can charge up your mobile before your power bank run out of power. If you are looking for the a device that can keep your mobile phone charge for long hours than go for the best power bank that has high capacity. We will be discussing about the power banks and what features you should look when buying a power bank later in this article.

Smart Phones and Their Uses

The latest addition to Sony’s flagship series Xperia is perhaps one of the most interesting of all the announcements made in the CES 2013 in Las Vegas. Sony has high hopes for Xperia Z with impressive specifications. Even critics have been positive about the Smartphone. It has an aesthetically pleasing form, as is typical of Sony Smartphones. The contours are slightly rounded, but the rectangular shape is retained. As of now, Sony Xperia Z is slated to be launched in three colors, namely, black, white and purple.

Sony Xperia Z has a sprawling 5 inch Full HD Retina display with 1920 x 1080 p resolution and 441 ppi pixel density. Even though Retina display is not unique for the phone (iPhone 5 has a similar one), combined with the resolution and pixel density, it is certainly one of the brightest. Using Mobile Bravia Engine 2 has significantly advanced the display. Sony has truly upped the game with Xperia Z in terms of visuals. At 146 g, it is not one of the heaviest phones around. But don’t let that fool you; the handset is power packed with a quad core Qualcomm Snapdragon S4 processor clocked at 1.5 GHz.

It has a Adeno 320 GPU. Along with the advanced GPU and 2 GB of RAM, this phone is certainly a good pick if you are a heavy gamer. It also contributes to smooth multi-tasking and a fluid user interface. The internal storage is a staggering 16 GB, which can be extended to 32 GB using microSD card. The phone has a brilliant 13 MP rear camera equipped with auto focus and LED Flash. It can even shoot Full HD videos. The front camera is of 2.2 MP, again, with Full HD video. It is quite remarkable for a camera used mostly for video chatting. The phone runs on a standard 2330 mAh Li-ion battery. But since the battery is non-removable, some potential users are having second thoughts about the Smartphone. Connectivity of the phone is pretty standard: Bluetooth 4.0, dual band Wi-Fi, GPS and DLNA. The phone also has Near Field Communication or NFC capabilities.

What are power banks

power banks in India
Power banks are portable device that is made of special type of battery called Lithium-ion (or Lithium-Polymer) that is enclosed in a special case and also have a electronic circuit that controls the flow of power. These power banks can hold electrical charge which can be later use to charge your smart phones, tablets and other portable media devices. The power banks are small in size and light in weight and hence they can be easily carried in a bag or pocket.

The Power Banks we’re talking about are good for almost any USB-charged devices. A Power Bank you can charge by connecting it to a power outlet. In simple, it’s mean how‘healthy’ your phone battery is. Power Banks come in different sizes and the mAh figure tells us the total capacity of the batteries. Cameras, GoPros, Portable speakers, GPS systems, MP3 players, smartphones and even some tablets can be charged from a Power Bank – practically anything that charges from USB at home can be charged from a Power Bank – you just have to remember to keep your Power Bank charged, too!

  • Most Power Banks use USB powered.
  • Phone battery storage capacity will be lower and lower.
  • In other words, the more mAh the Power Bank has, the larger the energy is.
  • Modern gadgets are power hungry.
  • This means that a power bank, like a smartphone, iPad or GPS system is charging by connecting it to a USB charger (which comes standard with most smartphones and tablets) or those with an often USB cable to connect to a computer.

That’s also the reason why our phone can last longer when it’s newly bought than after 3-6 months we used it. To give an example, iPhone 6 Plus has a battery capacity of 2915mAh so if you want to have it fully charged, you should have a Power Bank with more mAh than your phone’s capacity. Our increasingly busy lives mean a dead battery can leave you disconnected from life, work, and your daily routine. Power Banks, suitable for charging laptops are often charged by a supplied adapter. Different mobile phone models also will affect the calculation as some phone drain battery faster than the other. he normal lithium polymer batteries have a longer life expectancy than 18,650 cylindrical lithium ion batteries, and their security risk is relatively low.

Choosing the right power bank in India

In present day, we use electronic devices on day-to-day basis, such as our mobile phones, tablets. Portable chargers and power banks will keep you from getting stranded when you’re on the go and without a convenient charging source. Solar Power Banks are in addition to the standard method of charging (USB or adapter) also charged by a solar panel that is part of the Power Bank. The former one normally can be used for two or three years. The problem with these so powerful devices we are using is that it consumes a lot of energy, and they could drain their own batteries in such a short time.

They are ideal for recharging your smartphones and similar devices wherever you are when you find yourself low on power. Working out how many times a power bank will charge your phone depends on more than the mAh rating on the packaging. Mobile power bank circuit board can be treated as a control system, which is mainly responsible for power distribution and transformation. Of course, without energy, these so smart, and so expensive devices are useless and worth as much as paperweights. No power bank is 100 percent energy-efficient, with every portable charger losing power through voltage conversion and heat generated.

It converts the voltage provided by lithium batteries into the standard voltage to provide electricity for charging device. So, power bank can serve this purpose perfectly. The industry standard for energy efficiency is between 60- and 70 percent, but some of the best can offer 90 percent efficiency. Good Protection board has a conversion rate of up to 90%, while a general one has 80 ~ 85% and a bad one has only 70%. It the conversion rate is less than 80%, it means that the power bank suffers large line loss, and the battery cell itself suffers large calorific value. It could energize your devices back to life and prolong the usage of your devices for hours.
