One of the most common gestures that we users have internalized is, without a doubt, charging your iPhone's battery at night. But without a doubt, overnight charging of electronic devices, especially the increasingly ubiquitous smartphones, has been the subject of debate and concern almost since the standardization of mobile phones.
Exploring the science behind modern batteries and challenging long-held myths, in this article we'll tell you why overnight charging can be a safe and convenient practice that carries no risk to you or your phone.
Why isn't it bad to let your iPhone charge overnight?
Excess heat does not affect phone charging
One of the arguments used by critics of charging the phone while you sleep is that the phone actually generates heat and, therefore, that excessive heat is not good for it.
However, in the case of iPhones and other modern devices, Advances in thermal management technology have greatly mitigated this risk, as they are designed with efficient cooling systems and built-in sensors that closely monitor the device's temperature during charging.
In addition, Apple power adapters and charging cables are designed to minimize heat buildup and cut off the supply in case they detect any anomaly in the charging process.
Optimized charging cycles: a smart charging design
One of the innovations that have been happening for some years “for here”, Is the optimization of optimized charging cycles. These systems use intelligent algorithms to control the charging and discharging of the battery, thus optimizing its performance and prolonging its useful life.
To do it The phone constantly monitors the temperature to prevent overheating based on internal sensors, in addition to having a very efficient energy management system that is responsible for supplying the phone with the energy it needs according to the tasks it has to perform and also usually limits the charge when it reaches 100% battery (or even a little earlier), to avoid overloads and damage to it.
Additionally, modern iPhones are equipped with technologies such as adaptive charging, which Adjusts charging speed based on battery and device conditions, minimizing stress on the battery and reducing wear and tear over time. All of this helps make charging your iPhone battery at night safe.
Batteries are longer lasting: lithium is the key
The batteries we use today, based on Lithium ion technology, They are much more durable than the ones we used in the past, largely because they have a higher energy density and longer lifespan compared to older batteries, such as nickel-metal hydride (NiMH) or nickel-cadmium (NiCd) batteries.
In addition, they are compatible with electronic elements that guarantee that it is charged in the safest way possible: the BMS, which are the parts that are responsible for managing the balancing of the battery and its overall charging.
And as an extra point to the technological improvements, we cannot forget the latest innovations in battery charging: battery cooling and dissipation systems like the rumored one that the iPhone 16 will have, which guarantees to prevent overheating and ensure that the life of the battery is still extended.
How to improve the battery charge of your iPhone?
Have the Optimized Recharge option activated
Among the charging options that our iPhones offer us, there is one that is quite interesting and worth taking into account: the Optimized Recharge.
This feature uses advanced algorithms to Learn the user's charging habits and optimize the battery charging process accordingly, helping us prolong battery life by achieving the best mix of performance/battery charging for our iPhone.
In addition, as if it were the icing on the cake, this function can also take into account environmental factors, such as temperature, in order to adapt to the conditions and ensure safe and efficient charging so that you can charge your iPhone at night without fear or associated problems. .
Use original and certified chargers
I think there is no need to insist too much, but if you are still one of those who think that using “the Chinese charger” That's okay... we encourage you to think again and use original brand accessories or accessories certified by Apple or at least a recognized manufacturer.
Think that, if a charger is cheap, it is because its internal components are usually of much worse quality than the components of top brand chargers, and may have serious security flaws which could turn your nightly charging experience into a nightmare.
Remove phone case to charge
If you are still concerned about heat and you have a rather thick case, removing it to charge your iPhone's battery at night can be an interesting practice to avoid overheating.
Some covers, for example the famous “rugged”, Or the 360 rubber, They can interfere with the phone's heat dissipation process, which could cause it to become hotter than desired during charging. Not only can this affect charging efficiency, but it could also contribute to premature battery wear.
And we have given as an example two types of cases that are totally inadvisable, since they create an “oven” effect on the phone without letting the heat escape efficiently, something that will undoubtedly affect the life of your mobile terminal in the long term.
By removing the phone case before charging, you allow for better ventilation and heat dissipation, which can help maintain a more optimal temperature during the charging process.
However, we also tell you that in the vast majority of cases that exist in this market, this effect of lower heat dissipation is barely noticeable, so You really don't need to take it out, unless you use a case that completely covers the phone.
