A phone is nothing without its battery and it's frustrating to find that one night's charge runs out soon on new smartphones. After seeing why the battery of smartphone mobile phones lasts so little, let's discuss 3 myths concerning the batteries of electronic devices (cell phones, cameras, laptops, etc.), three large hoaxes that are often also mentioned by important magazines and technology sites .
Here are 3 important things to know to prolong and conserve battery power .
1) Discharging the battery completely does not extend its life and subsequent charges .
That practice of completely discharging a battery and then recharging it is true, indeed it was true, only for the batteries of older laptops, nickel-cadmium (NiCd).
Since NiCad batteries suffer from the so-called memory effect, recharging a non-exhausted battery causes a lowering of the total charge.
Today NiCad batteries are no longer used, replaced by lithium ion (Li-Ion) batteries.
With this type of technology, fully discharging the battery can ruin it.
Battery charge is determined by voltage, and most Li-Ion batteries operate between 3.3 (empty) and 4.2 volts (fully charged).
If you go below or go above this range of values, the battery, to compensate for the shock, loses some of its charge capacity (measured in Milliamps per hour mAh).
When the battery charge drops below 50-30 percent charge, it can already be recharged.
2) Temperature affects battery life
Forget the cell phone in cars, in the summer, in the sun, for a few hours at more than 40 degrees, it will cause the final death of the battery.
The chemicals inside run out with heat and in fact, on the batteries themselves it is often written not to leave them below temperatures above 40 or 45 degrees.
The cold instead preserves the health of the batteries of electronic devices and it is better to keep an unused battery in the fridge rather than at room temperature.
The important thing is not to keep it below 0 degrees.
3) Do not store a discharged or completely full battery for long periods of unused time .
The lithium battery, unfortunately, deteriorates over time whether it is used or not.
It loses power whether it remains completely discharged for too long or whether it is fully charged. This is because charged batteries are more chemically active and store more potential energy; the more juice they have, the more likely their internal chemicals will crystallize in the long run.
This results in a permanent loss of charge capacity.
Ideally, a battery should always be between 40% and 70% charged.
Batteries still remain the Achilles' heel of every electronic device and there are no significant improvements in charging capabilities on the horizon.
Those who need more reassurance and sources regarding what is written in this post can read further instructions on the BatteryUniversity website.
In particular, it is clear that a battery after 250 charging cycles gradually loses power and that is why after a couple of years any battery lasts less.
