ZeroLemon: The Solution for Power Guzzling Smartphones

As the world waits for the launch of the new iPhone, can you guess the most requested feature? You may be surprised to know that it is not the fingerprint scanner or a better camera. According to a poll conducted by USA Today, the most requested feature in the new iPhone is improved battery life! The iPhone (or for that matter, any smartphone) guzzles power like a thirsty horse drinking water out of a river. It’s not just Smartphones, Tablets, or Phablets that guzzle power. With the launch of the Samsung Galaxy Gear Smartwatch, wearable gadgets need powerful batteries too.

Since the launch of the first iPhone, there have been numerous advances in smartphone technology. Better processors, more memory, increasing storage, and better cameras. The only thing that does not seem to have improved much over the years is the battery.

I have used many smartphones over the years, and all of them had the same problem; a battery that runs out when I was about to send an important email at the end of the day. Or, when I needed to call home to say I am on my way.

Over the years, I have tried many battery solutions and different ways to ensure my battery remained charged:

  • Mophie Juicepack Air –  Mophie is  a case for your smartphone that also includes a battery. The battery in the case charges the smartphone’s internal battery. The disadvantage of the Mophie is the lead time for charging your phone. When you are on a call, you are consuming a lot of power. Battery charging is a slow process and Consumption is always faster than Charging.
  • iGo Green USB charger –  iGo Green is a battery that plugs into the wall for charging. Once the iGo Green is charged, you can charge your smartphone through a built-in USB port. The disadvantage of the iGo green is that you need to charge the battery first. If the battery is already drained when you need to charge your phone, you are out of luck.
  • Spare charger – Of course, you could leave one charger at work and one at home. What about the car and the meeting room? Or the transit? I can think of too many situations where you need to charge your phone and it is practically impossible to have a charger everywhere.
  • Predictive usage – If your battery goes below 10% stop watching the YouTube video and wait till you get home! Believe me, I have tried this too.

A smartphone cannot work without a charge and you are disconnected from work, home, and friends when your battery runs out. I was wondering how to ensure that my smartphone’s battery stays charged for at least 12 hours. If I could get through the day without losing charge, I could charge my phone when I got home. With superior battery technology not coming anytime soon, I had to look for a solution to stay connected.

Then I found the perfect solution – ZeroLemon.

The ZeroLemon battery is a 7000 mAH (milli-Ampere Hour) battery as compared to the original 2100 mAH battery that comes with the Samsung Galaxy S3. It is obviously more than three times the original capacity. The ZeroLemon battery takes 6 hours to charge and lasts 3 days even with heavy use! Even when I used my S3 for calls, texting, social media, Internet, Netflix, flash photography, and email, ZeroLemon refused to die.

Here are a few photos of the battery that has truly changed the way I use my smartphone:

Finally, if you are interested in comparing the thickness:

The Samsung Galaxy S3 surely gets a bit bulkier with the ZeroLemon battery. However, it is interesting to note that it is less bulkier than the OtterBox case. For a little additional weight, you get three days worth of battery. Now, you can always stay connected.

Here are the battery usage statistics from my Samsung Galaxy S3 when the ZeroLemon battery was about to run out. As you can see, the battery lasted me a full 2 days and 19 hours with 3% remaining:

ZeroLemon is available on Amazon. ZeroLemon sells extended batteries for many Android phones. Sadly, they do not sell an extended battery for the iPhone. Try out the Zero Lemon battery and let me know how you liked it.

Is the Smartphone Industry ‘Curious’ about Curiosity?

The world holds its breath as the next battle for dominance in the smartphone industry begins with the launch of the Samsung Galaxy S4. Apple recently defeated Samsung in a patent lawsuit involving user-interface elements. Samsung lost the battle, but they don’t necessarily have to lose the war. Samsung will not fade away into the night without putting up an aggressive fight. Samsung plans to sue Apple on its using the LTE (a technology for faster data speeds called Long-Term Evolution) chip in the iPhone 5.

As the smartphone war rages on, it is evident that there are many areas where industry giants compete for dominance – user-interface, operating system, physical design, connectivity, storage, and camera.

But there is one area where companies haven’t done much – the battery. Until the smartphone industry invests heavily into battery technology, devices are limited to what they can do on a single charge. Lithium-ion batteries are used extensively in all smartphones as of today. The life of a single charge is a few hours (assuming a user talks, texts, and uses data connections such as Wi-Fi or 3G/LTE). After a smartphone runs out of battery, users have no option but to carry a charging cable, USB charger, portable USB charger, a battery pack (like Mophie), or just wait to reach home to charge the phone.

Talking about battery life, the smartphone industry can learn a lot from the Mars Rover Curiosity. Curiosity has reached Mars and has starting sending photos, conducting experiments and, exploring the Martian mountains. For doing all this, Curiosity needs one thing – power.

Previous generations of Mars Rovers used solar panels to power various devices. However, dust settled on the solar panels making them inefficient. Also, note that the Sun looks much smaller from Mars as Mars is at a greater distance from the center of the solar system. Smaller sun = less light = less solar power.

To solve this problem of inefficient solar power, Curiosity uses a Multi-Mission Radioisotope Thermoelectric Generator (MMRTG). Simply put, Curiosity uses the radioactive isotope Plutonium-238 as the raw material. Heat is automatically generated due to the natural decay of Plutonium-238. A device called a Thermocouple uses this heat to generate electricity. The Plutonium-238 is well shielded, and the heat – and not the radiation – is used to generate electricity. This device can last for 14 years without requiring any maintenance! Curiosity will constantly receive its power until Plutonium-238 completely decays.

Now, coming back to the smartphone industry, why can’t we design something like this for smartphones? Imagine having a very small amount of radioactive isotope that is well-shielded and attached to the smartphone. The device could then, theoretically, produce electricity for at least a year (or more!). Instead of battery packs like Mophie, we could have smartphones that generate their power and don’t need a recharge! Depending on the stability of the technology, we could have a smartphone that could last for years without a recharge. You buy a smartphone and dispose of it after a few years without charging it even once.

When I told my wife about this idea, she said, and I quote: ‘I am not carrying a nuclear bomb in my pocket!’. Well, what I am proposing is not exactly a nuclear bomb since there is no chain reaction like nuclear fission or nuclear fusion going on. The natural decay of Plutonium-238 generates heat and hence the power. Theoretically, a well-shielded pack of Plutonium-238 is safer than batteries that we have today. The current batteries have greater chances of exploding than a well-shielded pack of Plutonium-238!

The future of the smartphone industry is uncertain. There are no obvious winners as of today. In my opinion, only the company that designs and patents advanced battery technology will emerge as the winner. The company holding the key to advanced battery technology will be the undisputed winner and will rule the smartphone industry for generations to come. Simply because, more power equals to more things the smartphone can do without dying.

Hey Apple and Samsung – are you listening? Hopefully, I can expect to be paid a billion dollars for my idea!
