It is often the habit of mobile phone users to charge their terminal, often evening until morning. However, it may turn out harmful to many ways for the battery and phone itself.
Charging your phone overnight can damage its battery and shorten its lifespan. Here I explain to you the reasons why it is better to avoid it.
Why not put the phone on charge at night
Battery life is one of the most important criteria for choosing a phone. It depends on the use of the mobile in terms of applications and data transfers.
The objective being to have the full energy before starting the day to avoid an untimely breakdown often leads to the reflex to put the mobile in charge in the evening.
Premature deterioration of battery life
The majority of cell phones are equipped witha lithium-ion battery that recharges in a few hours.
While you sleep, the phone can stay plugged in for 6 to 8 hours or even longer overnight.
For safety reasons, manufacturers have developed a system that automatically terminates charging when the battery is at 100%. Even if it remains connected to the mains, the telephone can no longer charge.
However, the repetition of this phenomenon several times during the night ends up wearing out your phone's battery, which ends up after a more or less long period of time no longer holding a charge at all. The battery sometimes drains in a few moments.
Most cell phone and battery manufacturers recommend that you keep the charge level between 30% and 80%.
Using a charger that is not original
It is always recommended touse the original charger supplied with your cell phone. Another charger may have the compatible tip, but have a totally different amperage.
Three negative consequences can occur in relation to an inadequate amperage:
- Usually longer charging time.
- The risk of your phone overheating.
- Shorter battery life. Most of the time, overheating issues are the root cause.
A risk of terminal fire
Even if this risk is minimal, leave too long a charging phone can cause a fire.
There can always be the risk of malfunction or even overheating when an electrical appliance remains connected to the mains.
There may be power peaks linked in particular to certain meteorological conditions.
The case happened with a relatively Samsung branded terminal: a galaxy note 7.
Manufacturer's recommendations
The manufacturer's recommendations are generally listed on the mobile phone user manual which is provided for purchase.
Among them are some tips that allow users to extend the life of the battery as well as the phone.
The "smart" charge of your phone
The charge limit is important information, and smartphone manufacturers recommend that youavoid recharging a phone up to 100%.
Some latest generation smartphones, including iPhones and other phone brands like Huawei send a notification and suspend charging as soon as the battery reaches 80%. Phone manufacturers also recommend charge phones interval.
How to take good care of your smartphone battery?
It is important to save your battery so that it lasts as long as possible, the very act of recharging it requires some precautions to avoid damaging it.
Theoretically, lithium-ion batteries current support on average between 500 and 1000 cycles before finally giving up the ghost.
It is not useful to wait until its battery is less than 5% to charge it, it is even strongly discouraged. A complete cycle, of 0 to 100%, is in fact only recommended when the display no longer seems to correspond to reality. This will act a bit like a battery reset.
Brightness and dark mode settings
Here are two tips that allow you to significantly gain autonomy:
- Lower the intensity of the lighting on your screen. Brightness that is too bright is not only bad for your battery, it is also bad for your eyes. It is even advisable to set the brightness to "automatic" so that it adapts to the surrounding light.
- Switch to a dark mode in its operating system. This relieves the eye because the screens then emit less blue light. This is even more true in the evening, just before going to bed: the dark mode is therefore strongly recommended. The most recent versions also allow you to define a time range for this lighting parameter.
Energy saving and application shutdowns
Adjusting your phone correctly from the start is the best guarantee for a battery that lasts and a device that does not overheat.
- Activate energy saving mode. It allows you to automatically restrict the activity of certain background applications (or even block some) and to deactivate certain visual effects.
- Make sure to close all applications that are not used a lot. It is advisable to make sure to close all the applications which one uses little and, conversely, to leave open those which are the most used, in particular those which concern the social networks. Indeed, restarting them constantly tends to use the battery.
Connectivity and geolocation settings
- Wireless connection. If there is something that consumes energy, it is to connect in Bluetooth, in wifi and in mobile data. The antennas are particularly energy intensive, especially the 4G ! We must take care disable this type of connection, otherwise the device will be constantly looking for a new one nearby. This means that if you must use this type of connection, you should be sure to deactivate it when you are done.
- Limit the use of geolocation. THE'using GPS also requires a lot of energy. In this case, do not hesitate to go to the settings of your device to allow access to the location of only a few applications. Also be sure to turn it off the rest of the time.
