At Tesco Mobile, we like to keep on top of the latest developments in smartphone technology, and recently we’ve been swotting up on the future of mobile phone batteries. We’ve all felt the frustration that comes with the all too finite life of phones which, while we love them dearly, have a tendency to run out of charge when we need them the most. But could this anxiety soon be a thing of the past?
The science of smartphone batteries
Let’s have a quick – and ashamedly basic – science lesson. Despite often being described as lithium, the battery inside the majority of smartphones is made from a variety of elements. A battery with more parts made from lithium would last an awful lot longer, but a viable model has yet to be developed.
The lithium component of current batteries is found in the electrolyte, and if other components could be made from the metal, then our batteries would last longer. Sadly, the current crop of mobile phone batteries are close to the pinnacle of what current science can offer – but what does the future hold?
Smartphone batteries of the future
The development of new batteries is a tricky and fast-paced field, with new battery types constantly being developed, trialled, and all too often cast aside due to major issues. As a result, predicting the next step in the evolution of mobile phone batteries is exceptionally difficult – but here are three batteries from the next generation that we think have real potential.
Aluminium graphite batteries: Full charge in just 60 seconds?
Scientists at Stanford University have recently developed a new form of ultra-fast aluminium graphite battery which it is claimed can charge a smartphone in just 60 seconds. Historically, the problem with aluminium-based power sources has been the struggle to repeatedly charge without losing capacity, but this new form of aluminium battery can be charged up to 7,500 times without any detrimental effects. Given that the capacity of most current batteries begins to decline after just 1,000 charges – this certainly sounds promising!
Wireless charging: Electricity in the air?
Developed by uBeam, these batteries use ultrasound to transmit electricity through the air. Power is first converted into ultrasound waves, beamed to your phone and then converted back into electricity – so plugging in to charge could soon be a thing of the past! Your smartphone just needs a thin receiver to pick up this wireless charge, so you’ll be able to power up your phone while moving around the house.
Solar charging: Here comes the sun
If you’ve always dreamed of charging your phone from a burning ball of gas that’s over 90 million miles away, we’ve got great news. Development is currently underway on a transparent solar panel that can be placed over your phone screen, charging your phone whenever it’s exposed to sunlight. What’s more, this super-thin panel won’t stop you using your touch screen!
Saving power on current mobile phone batteries
In our opinion, all three of these interesting new battery types could be the future of smartphone charging – so keep your eyes peeled for them in the months and years to come! For now however, be sure to check out our dedicated guide to making the most of your current smartphones battery life.
