How long does a battery last?
Battery life is an important factor when purchasing a battery-powered device.
The big question then, of course, is how long will the battery last before it wears out?
The life of a battery depends on a number of factors: its chemical makeup, total capacity and number of charge cycles.
In devices such as a laptop, tablet or smartphone, a lithium battery is almost always chosen. Lithium batteries are used because they charge faster, last longer and can store more energy in a small package than other technologies.
Because the technologies for batteries are often the same between different devices, we can make estimates about the average lifespan. The average lifespan is about 3 years.
When people talk about the life of a battery, they actually mean the period during which the battery degrades from 100% capacity to 80%. So this means that in some cases the battery may still function in reduced capacity on some devices. This takes about 300-500 charging cycles.
Note! It is not only the capacity of the battery that decreases, the voltage it can deliver also weakens. Specifically, this means that your device may fail or fail to boot from the battery and even refuse to charge it.
It is important to replace these batteries safely and recycle the old battery safely. Used batteries exposed to oxygen or heat can catch fire or even explode.
Conclusion
The more often you use your device, the faster your battery wears out. Handle used batteries carefully and recycle them properly.
Replace your battery promptly to avoid problems!
