While nickel batteries in phones used to have a memory effect, meaning you had to charge them to 100% for them to remember their full capacity, this is not the case today. Not only do you not have to fully charge your battery, but this is also no longer advisable.
At present, it is best to charge the battery so that it does not fully charge or fully discharge. We are going to tell you the main reasons why this is the case and what is the ideal percentage to maintain the charge levels of your phone.
Battery gets stressed on full charges
Although you may think that charging your phone to 100% is the most advisable because it allows you to get the most out of the charge during the day, using a high voltage charger can affect the battery. The best in this case is to reach a maximum of 70-90% for the optimal use of the battery charge. The maximum capacity in lithium-ion batteries stresses the battery because the highest voltage occurs when it is fully discharged or fully charged.
It is even better that it is completely depleted than that it is fully charged. In this way, if you charge the battery in partial charges throughout the day when you need it, you will reduce its stress and its natural aging.
Although it must also be taken into account that the new mobiles are already prepared for it and it is not so serious if you leave the battery at 100% or charging overnight. In some, the input flow is disconnected when they fully charge, and if it is reduced, it will activate the load again in small intervals. Of course, this small degradation would also occur when exceeding the 80% load continuously, even if only in the long term.
20-80% better, depending on studies
There are several studies that state that the battery should be kept between 20 and 80% because this is beneficial for its lifespan. Others point out that it is best for mobile phones to have a charge between 40 and 80%, there are even those who say that the best is between 40 and 60%. The truth is that none of them recommend charging more than 100%.
When the charge rises above 80% , the ion cells of the battery are forced and degraded, causing their health to suffer and their autonomy to drop . The reasons are the same, these charge levels stress the batteries.
The mobile can get overheated
If you charge the battery to 100%, there may be some cases where the mobile ends up overheating due to spending a long time charging or for other reasons, especially if you have a charger that is not the original one.
In many cases, considering that there are phone models that do not come with their charger, we opt for one that is not the original to save money. This affects the batteries of our phones and can considerably damage the charges, something that happens more frequently when they are full.
Also, taking into account that fast charging can affect batteries in the long term, making a charge of this type at 100% will increase these possibilities and can also heat up your mobile. If you are going to do this type of load taking advantage of the potential of your mobile, it is best that you do it in a lower percentage and occasionally, not always.
