Do not charge your phone to 100% - is it a myth?

One common advice given by smartphone experts is not to charge your device up to 100%. According to some sources, fully charging your phone may not be the best thing for your phone's battery life. But is this advice true or just a myth?

Many experts say that lithium-ion batteries, found in most smartphones, do not like to be fully charged and warm. So, when you charge your phone up to 100% and then use it for a long time or keep it exposed to heat, it can negatively affect the lifespan of the battery.

The ideal way to optimize your battery life, according to some engineers, is to keep your phone between 20% and 80% charge. While this may be an inconvenience for many, it is suggested that going below 20% and even above 80% can actually shorten your battery's life.

The fewer cycles your phone's battery goes through, the less charge it can hold. In simpler terms, the shorter the life of the battery, too. So, the goal is to keep those cycles to a minimum by keeping a charge between 20% and 80%.

One silver lining to this advice is that it is not limited to smartphones but true for all Li-ion batteries, including those of an electric car. Following this piece of advice may also ensure maximum battery life for other devices that run on Li-ion batteries.

On the bright side, recent advancements in charging technology have also made it possible to fast-charge your phone up to 80% quicker than ever before. However, it's still recommended to stop at 80% rather than fully charging your phone, especially if you want to increase your battery's lifespan.

In conclusion, while it may seem like a hassle to keep your phone's battery between 20% and 80%, doing so can actually help prolong its life. Following this suggestion can bring out the best battery life of your phone while also maximizing the capacity and lifespan of the battery.
