A lot of the sci-fi series that focus on the future of humankind envision communication-entertainment converged devices, usually disc-shaped, fitted into the side of people’s foreheads. We’re not very far from that given how dependent we are on our smartphones today.
And who can blame us? We need our smartphones for communicating, for work, for entertainment of various sorts, for news updates and research, for navigation, for finding our keys, opening our doors and turning on our lights with the help of an app among other things. Most of the best phones under 25000 INR pretty much play the roles of personal assistants to their owners in many ways.
Given the dependence on our smartphones and the level of convenience that they bring to our lives, it is about time that batteries take centre stage in the research and development arena. A lot of manufacturers are ensuring 4000 mAh to 6000 mAh battery phones even in the mid-range segment. Especially for users willing to shell out for the best phone under 25,000 INR, 6000 mAh battery phones are the norm.
But 6000 mAh battery phones are no longer breaking news. Graphene is the new buzzword in forward-looking mobile tech. Manufacturers like market-leaders Samsung and Xiaomi are, as usual, being quick to respond to, and pick up, the new technology. Samsung is rumoured to have a graphene battery smartphone in the pipeline, and Xiaomi has already launched the M10 Ultra that comes with a graphene-enhanced battery.
As the first smartphone to have graphene as an essential ingredient in its battery, the M10 Ultra is witnessing popular reviews on forums and discussion boards. Of course, if your search for a phone reads like “best phone under 25,000 INR”, then you’re going to be slightly disappointed because the M10 Ultra is currently retailing anywhere between 63,000 INR and 73,000 INR.
So what is graphene?
Graphene is a nanomaterial, or a material that is developed to be used in miniscule quantities, and exhibits some amazing features, such as increased conductivity or increased strength.
Why is it such a big deal?
Graphene has several of the said amazing features to its credit. The most relevant among these is that it has very high thermal and electrical conductivity. It is, in this regard, that graphene is seen to be more efficient than lithium, as a raw material for mobile batteries. According to a company that manufactures graphene batteries, these heavyweights can charge much faster and retain more charge. Incidentally, Samsung says that its graphene battery smartphone will be able to attain full charge in just 12 minutes! Now that’s a big claim, and one that users will be delighted to see come to fruition.
Is the M10 the only phone with a graphene battery?
At present, it seems to be so. Apple might have one in an upcoming model and Samsung, as mentioned, allegedly has one such smartphone in the pipeline. Manufacturers seem to be trying to figure out how to manage the cost of fitting phones with graphene (or graphene-enhanced) batteries.
Regardless of your preferences, you no longer have to get disheartened by the phone’s price tag. Just use the Bajaj Finserv EMI Network Card, and convert the cost of your new smartphone into convenient monthly instalments!
