Many market surveys have shown that battery life is one of the top areas where consumers want smartphones to improve. Most smartphones today still need to be charged daily, and many people have experienced the frustration of seeing their battery drop below 20%. Without access to a charger or power bank, this situation can be really inconvenient.
While smartphones have advanced rapidly in recent years, battery technology has lagged behind. However, some exciting breakthroughs are now emerging that could significantly extend mobile phone battery life.
**1. Superfast Charger That Is Full in Half a Minute**
The ultra-fast charging system from StoreDot has recently gained a lot of attention in the industry. It can charge a Galaxy S4 from 0% to 100% in just 30 seconds, which is truly impressive. In addition, it increases the number of charge cycles, helping to extend battery life and reduce long-term costs for users. While the technology is complex and may not hit the market immediately, it’s expected to be available by 2016.
**2. Use One Device to Charge Another**
Mobile power banks are not new, but some companies are taking it a step further. For example, Asus introduced the PadFone, which allows the tablet to charge the phone. ZTE’s Projector Hotspot combines a portable projector, 4G hotspot, and power bank into one device. Huawei’s Ascend Mate 2 even features reverse charging, allowing its large battery to provide emergency power to other devices.
**3. Large Battery Packs That Charge All Devices**
A 5000mAh battery pack might only charge an iPhone 5 twice, but the Trontium Reactor offers something completely different. This $300 metal cylinder uses USB Power Delivery technology to deliver up to 290W of power—enough to charge an iPhone 50 times or a MacBook Air five times. As this technology becomes more common, we can expect more powerful and versatile charging solutions in the future.
**4. Not a Battery, Not a Capacitor – It’s a Supercapacitor!**
Supercapacitors are a hybrid between batteries and capacitors. They charge quickly, store a lot of energy, and can handle thousands of charge-discharge cycles without degrading. The Blueshift Bamboo speaker, for example, can be charged in minutes and play for six hours. A 18-year-old student also demonstrated a supercapacitor battery at the Intel International Science and Engineering Fair, capable of charging a smartphone in 30 seconds.
**5. Various Shapes and Sizes of Batteries**
LG has been exploring new battery designs, including curved, stepped, and linear shapes, to better fit modern devices like smartwatches. The LG G2’s “child battery†design increased capacity by 16%, extending standby time by three hours. These innovations show how battery form factors are evolving to meet the needs of smaller and more flexible devices.
**6. Use Body Temperature to Charge Electronic Devices**
A South Korean research team has developed a thermoelectric generator that can convert body heat into electricity. This tiny device could power wearable tech and even be used in everyday gadgets, offering a new way to keep devices running without plugging in.
**7. Intelligent Software Optimization**
Qualcomm’s Quick Charge 2.0 technology doesn’t extend battery life directly, but it speeds up charging. With this technology, a 3300mAh battery can be charged 75% faster. However, both the phone and charger must support it, and it isn’t backward compatible.
**8. Mobile Phone Screen Equipped with Solar Panels**
Adding solar panels to a smartphone screen can boost battery life by up to 15% under sunlight or artificial light. This technology was showcased at CES 2014 and could eventually allow low-power devices to operate without traditional chargers. Luxury brand Tag Heuer has already integrated this feature into a high-end smartphone.
**9. Lithium-Ion and Silicon Electrode Batteries**
Most modern devices use lithium-ion batteries, but researchers are now focusing on silicon-based electrodes. These offer higher capacity, longer life, and better stability. Silicon electrode batteries are expected to become available in consumer electronics by late 2014.
**10. Wireless Charging When You Enter the Room**
Wireless charging has been around for a while, but a new system called DCRS (Diver Coil Resonance System) can charge up to 40 devices within 5 meters. Though still in development, this technology could one day allow phones to charge automatically as you walk into a room—like Wi-Fi, but for power.
These advancements show that the future of mobile battery life is bright, and we’re likely to see major improvements in the coming years.
