Lithium batteries are among the most widely used in the world today, powering smartphones, laptops, electric vehicles, and all kinds of devices. However, although highly efficient, lithium-ion batteries degrade over time , gradually losing their energy storage capacity.
In this article we will discover what lithium battery degradation is , what the main causes are and practical advice to slow it down, thus prolonging the useful life of the device.

⚡ WHAT IS LITHIUM BATTERY DEGRADATION?
The degradation of a lithium battery is a natural and irreversible process that involves the progressive loss of energy capacity and an increase in internal resistance. This means that, over time and with multiple charging cycles, the battery:
-
It discharges faster;
-
Takes longer to load;
-
It no longer reaches its original capacity (e.g. from 100% to 80%).
📊 MAIN CAUSES OF DEGRADATION
1. Number of charge/discharge cycles
Each battery has a "useful life" expressed in complete cycles (usually between 500 and 1,000). One cycle corresponds to a full charge from 0% to 100%. Intensive use accelerates degradation.
2. High temperatures
One of the worst enemies of batteries is heat . Constant use in environments above 35°C can lead to a 20% reduction in capacity in just a few years .
3. Prolonged deep discharge (0%)
Leaving the battery completely discharged for extended periods damages its internal chemistry. Storing it at 0% charge for weeks is also strongly discouraged.
4. Frequent overload (100%)
Even keeping your battery at 100% all the time can cause chemical stress. Over time, this degrades performance.
✅ GOOD HABITS TO EXTEND BATTERY LIFE
Scientific studies have shown that careful behavior can significantly slow down degradation . Here are the main golden rules:
-
✉️ Keep the charge between 20% and 80% : avoid complete discharges and constant 100% recharges;
-
❄️ Avoid extreme temperatures : Do not leave your device under the sun or in the car during the summer;
-
🌐 Enable optimized charging (available on many modern smartphones and laptops);
-
🚪 Do not use the appliance while it is being heavily charged;
-
♻️ Use original or certified chargers to ensure correct voltages and amperages.
⏳ HOW LONG DOES A LITHIUM BATTERY LAST?
Under normal conditions, a lithium battery can last between 3 and 5 years , or approximately 300-1,000 complete charge cycles . Proper care can yield superior results and maintain good performance even beyond the fourth year of use.
🤔 FREQUENTLY ASKED QUESTIONS
🚗 Do electric cars suffer from battery degradation?
Yes, although battery management systems (BMS) are designed to control temperature, charging and discharging, limiting wear.
🚫 Can I leave my laptop plugged in all the time?
It's best to avoid it. If necessary, activate the "battery protection" mode available on many devices to limit the charge to 80%.
🚧 Should I replace the battery if the capacity drops below 80%?
It depends on usage. If performance is compromised, we recommend replacing it with an original or certified battery.
