Smartphones have been in our lives for almost twenty years, and we’ve seen enormous enhancements in that point. Nevertheless, one factor has principally remained the identical—charging your cellphone day by day. Why hasn’t battery life gotten higher together with every little thing else?
Larger, high-resolution shows, highly effective processors, clever software program options, and sooner information speeds are only a few of the enhancements through the years. But with all of these developments in know-how, I’m nonetheless charging my phone every night like I used to be in 2009.

Why Is Smartphone Battery Life Nonetheless Unhealthy?
You may make a reasonably stable argument that battery life has truly gotten worse. Earlier than smartphones, cell telephones may final for a number of days on a cost. After all, smartphones are rather more superior than these units, however shouldn’t batteries be advancing too?
The reality is that battery life for many smartphones is fairly unhealthy. Except you’re utilizing a super-mega-ultra mannequin—-such because the iPhone 14 Pro Max or Samsung Galaxy S22 Ultra—you’re in all probability preserving a detailed eye on the battery stage, and possibly even juicing up earlier than the tip of the day.
So what’s happening right here? It’s truly fairly easy while you get proper right down to it. Smartphones have gotten higher sooner than batteries have. Batteries have gotten higher through the years, however the developments are miniscule in comparison with these made in chips, shows, and different smartphone parts.
In truth, the unimaginable developments in other smartphone components are what’s preserving battery life within the one-day vary. Inner parts are shrinking, which makes room for larger batteries. That’s nonetheless the perfect reply we’ve got for enhancing battery life—throwing more mAh at the problem.
Sadly, the batteries present in smartphones immediately are nonetheless based mostly on know-how from the Nineteen Nineties. There have been massive developments in battery know-how between the 80s and 90s, however issues have stagnated since then. We’ve primarily reached the restrict of what we are able to squeeze out of lithium cobalt batteries.
Will Batteries Ever Get Higher?
The massive query is: Will we ever get out of this rut? Everyone seems to be ready for the subsequent massive development in battery know-how, however it by no means appears to return. I definitely by no means would have guessed we’d nonetheless be charging our telephones each day again after I bought my first one.
There are a few issues on the horizon to stay up for. The primary known as “stacked batteries,” and Samsung is reportedly planning to mass-produce them in the future. Stacked batteries are actually a number of cell sheets stacked on prime of one another to attain the next capability in the identical bodily footprint.
Don’t get your hopes up an excessive amount of, although. Stacked batteries solely enhance capability by round 10%. A cellphone with a 5,000mAh battery may match 5,500mAh with stacked battery know-how. We additionally don’t know when Samsung will truly begin implementing this tech—if it ever occurs.
Solid-state batteries are one other know-how that may very well be an answer. Typical batteries have two steel electrodes in a liquid electrolyte substance. Ionic particles transfer between the electrodes when charging and discharging.
Because the title implies, solid-state batteries are, properly, stable. The liquid electrolyte is changed with a stable piece of steel or alloy. The electrodes and electrolyte might be compressed into layers that may be flatter than a typical liquid-based battery. Meaning extra capability in the identical dimension package deal.
A a lot larger deal on this planet of battery know-how is Graphene. Graphene is a one-atom-thick crystalline lattice of graphite. Regardless of being almost 2D, Graphene is a superb electrical and thermal conductor, whereas nonetheless having a excessive stage of hardness and power. Graphene batteries would provide 60% extra capability than lithium-ion batteries in the identical dimension.
Sounds nice, proper? Certainly, Graphene is an unimaginable materials, however there are some massive roadblocks. Graphene may be very troublesome and costly to mass produce. It’s not possible to make a smartphone with a Graphene battery. At the moment, the perfect we are able to do is graphene/lithium hybrid batteries, which you’ll already buy from companies such as Elecjet.
Smartphones are merely advancing at a a lot greater price than batteries. It’s seemingly our telephones will demand much more energy by the point the subsequent massive battery breakthrough happens. Don’t count on to vary your nightly charging routine any time quickly. Within the meantime, your finest guess is to go for the best iPhone or best Android phone for battery life—or hold a number of portable chargers round.
