Smartphone Charging Technology Evolution

With the technology evolution, smartphones have become one of our basic need to communicate with friends, family and coworkers. Apart from communication, these smartphones are a modern day marvel, pocket-size computers that allow us to play 3D games, snap photos, video chat with friends and navigate around the world without ever stopping to ask for directions.

With evolution in smartphone technology, progression in battery technology can also be witnessed. As the smartphones are used continuously throughout the day therefore, it has increased the battery consumption rate, hence, increasing the demand of power revolution. Therefore, with increased usage of smartphones in daily life, better and efficient batteries have been introduced along with smarter charging solutions.

There are a lot of new fast-charging technologies, few of them are defined here:

Power Bank:

Most popular portable batteries used now a days are Power Banks. They allow you to store electrical energy (deposit it in the bank) and then later on use it as an external charger to charge up your mobile devices.Lithium-Ion and Lithium-Polymer batteries are the most common rechargeable cell types used in Power Banks.

Lithium-Ion cells are generally cheaper and limited in mAh capacity, while Lithium-Polymer cells can be larger and don’t affect memory over time.

Initially power banks become quite popular among smartphone users but the problem with Power Banks is that they cannot transfer 100% of their actual capacity to a device due to resistance

Wireless Charging:

Wireless Charging is also known as “Inductive Charging” because it uses magnetic induction and allows you to charge your smartphone without fiddling with USB plugs. Just place the smartphone on a wireless charger and it will start charging. Some standards are also designed to ensure that devices and wireless chargers from different companies can work together. There are three standards: Qi, PMA (Power Matter Alliance) Powermat, and A4WP (Alliance for Wireless Power).

Not all smartphones have wireless charging capability but many international companies like HTC, Google, Motorola, Samsung and Sony have introduced few smartphones that support wireless charging.

Wireless charging may not be as fast as a traditional plug-up, but being able to plop your phone on a wireless charging block can make a world of difference to the phone and its user

Apple does not have wireless technology enabled in its smartphones but is working to develop new wireless charging technology that could be deployed on its mobile devices as soon as.

However, wireless charging may not be as fast as a traditional plug-up, but being able to plop your phone on a wireless charging block can make a world of difference to the phone and its user.

Fast Charging:

Fast charging is the latest trend nowadays. With new Fast Charge technology, your mobile phone battery can go from zero to 50% in about 30 minutes, so you can spend less time connected to an outlet and more time connecting with people you care about.

Using certain Snapdragon–powered devices with a Quick Charge certified power adapter and any USB connector, including Type-C, you can refill the battery of enabled devices up to 4X faster than with conventional charging

Samsung Adaptive Fast Charging:

Samsung has introduced its own “Adaptive Fast Charging Technology”.

Wired Fast Charge is compatible with the

• Samsung Galaxy S6
• Galaxy Note 4
• later models of the Galaxy S and Galaxy Note series

Qualcomm Quick Charge 3.0:

Qualcomm, a popular SoC manufacturer introduced its own Quick Charge technology with Quick Charge 3.0 currently being promoted.

Using certain Snapdragon-powered devices with a Quick Charge certified power adapter and any USB connector, including Type-C, you can refill the battery of enabled devices up to 4X faster than with conventional charging. Quick Charge 3.0 can help devices like LG G5 achieve up to 80% charge in just 35 minutes. Other devices compatible with this charging technology are:

• Asus ZenFone 3, ZenFone 3 Deluxe, ZenFone 3 Ultra
• HTC 10, HTC One A9
• Lenovo ZUK Z2 Pro

Super VOOC (Voltage open loop multi-step constant-current charging)

Oppo’s newly introduced Wireless charger “Super VOOC” has led the technology to a even higher end. Oppo released its Super VOOC charger at Mobile World Congress (MWC) 2016.

The Super VOOC is capable of recharging a 2,500 mAh battery in just 15 minutes. It can also achieve about 45% of charge in 5 minutes.

Mobile Charging technology is advancing day by day and recent developments in wireless technology have opened new ways for developers to improve the mobile charging by making it faster and more reliable. We hope that soon we will see this high technology in our smartphones.
