2 REASONS WHY YOUR PHONE BATTERIES DON’T LAST

 2 REASONS WHY YOUR PHONE BATTERIES DON’T LAST

Chargers have become our loyal companions. For every device that we use, wherever we go, we must take its charger along, even if it’s for a day, Modern phones and tablets last mere hours on each charge, sometimes even less if you use high-end features. The problem has stumped researchers all this while: they just couldn’t figure out why phone batteries should die so quickly.
Finally, now, we have the answer. There are too main reasons, as it turns out:
1. Random movements of the lithium ions
If that sounds too scientific, it’s not. Most of the consumer devices that we use have lithium-ion batteries in them, and the electric charge they provide is a consequence of lithium ions moving through the battery as required. But the material in which the battery is manufactured has been found to cause random movement of lithium ions, thereby causing a ‘leak’ in charge. It’s a bit like how rust accumulates over steel, though this is ionic rust and cannot be seen.
2. Running batteries at higher charge
This is the second reason that can cause this leak of charge. It’s not unusual for us to disrupt charge cycles because we have to take a phone call or because we have to go somewhere. It’s also not unusual to charge a battery on different voltages. All of these practices can cause charge leakage by increasing the amount of randomness in the movement of lithium ions
These research findings could lead to more efficient electric batteries which will make electric cars a reality – cars in which batteries will last for days or even weeks on a single charge.
