Manufacturers and experts agree: maintaining a charge between 20 and 80% often doubles the number of complete cycles a battery can withstand before its autonomy decreases.
A full cycle is 100% of the charge consumed, not necessarily all at once. For example, recharging from 50% to 100% is half a cycle. The fewer full cycles the battery completes, the longer it lasts.
Should we change our habits?
It all depends on your usage:
- If your phone lasts 80-90% of the day, adopt this limit.
- If you need 100% to get through the day, no problem… but avoid leaving it plugged in long after you’ve reached full capacity.
The goal is to find a balance between ease of use and battery preservation.
What to remember
Charging to 100% every day, especially overnight, drains the battery faster. Keeping it between 20% and 80-90% as often as possible will preserve its battery life, reduce the risk of overheating, and prolong its performance.
A well-maintained battery means a phone that remains efficient… and less anxiety when the icon turns orange.
