+Identification of the needs Mobile phones, specially, smartphones have become part

of people’s everyday life. Consumers use smartphones for ~190 minutes per day =

~ 3 hours per day (Analysysmason.com, 2014) The more you use your mobile phone, the faster battery

runs out of power. Battery lifespan for smartphones still is a problem for

consumers (not always you have charger with you). New, innovative solutions should be made in order

to improve charging problems for mobile phones.

How to improve lifespan of your smartphone battery?

+Statistics of smartphone usageNumber of sold smartphones (sales in million units), 2007-2014

+Alternative mobile phone chargers Alternative power source to charge mobile phone devices is

use of solar energy to charge mobile phone with a wireless connection.

Disadvantages – limited ability to charge (depending on intensity of light) and use of cable.

+Alternative mobile phone chargers Mobile phones can be charged remotely, while in the

user’s pocket by applying the concept of MIMO (multiple-input multiple-output) beamforming.

Disadvantage – limited distance while charging the phone.

+Alternative mobile phone chargers Fuel cell charger that runs on water and salt (sodium

silicide and sodium borohydride).

Disadvantage – disposable pucks, pricey

+Alternative mobile phone chargers Wireless charging pad.

Disadvantages – need for a direct contact with the charging pad; compatible only with “friendly” devices.

+Integrated Induction Coil Charger1. Induction technology is

already happening2. It is has been used since

1980 and first it was implemented in electronic toothbrushes

3. The exact novelty consists in the way we want to use it

4. An improved performance induction coil can charge electronic devices via 1-4 cm physical distance which allows us to change the way we handle our technology

+SWOT analysisStrengths 1. Novelty in wireless

technology; 2. Convenience and

simplicity of operation; 3. Fresh and positive

approach; 4. Customer prepared and

expects new technology; 5. Suitable for people who

work simultaneously both with phone and computer;

6. Technology that could be used with other devices not only phones.

Weaknesses 1. Limited

range of operation; 2. Few or no

data about health impact;

3. Big power loses, not suitable for power save mode.

+SWOT analysisOpportunities 1. Increasing

smartphone markets; 2. Growing need to

have better battery performance;

3. Huge market from all over the world;

4. An epected 21st century technology with limitless possibilities;

5. Opportunity to transcend this technology to bigger distances.

Threats 1. Difficulties in

integrating the induction coil into the laptop;

2. Laptop companies will want a fat share even if the idea is patented;

3. Unknown long term usage features;

4. Copyrights issues.
