How not to ruin your smartphone battery: 5 useful tips

There drums it is one of the most delicate components of the mobile phone and, if it gets ruined, it will have to be replaced. The batteries in our smartphones are usually batteries lithium ions and are subject to what is defined chemical aging, a “physiological” process which decreases its duration or autonomy (i.e. the time interval for which the device can function before having to be recharged) and its life cycle (i.e. the period of time in which the battery is working properly). Although it cannot be made to last for decades, through some simple precautions – such as avoiding charging the phone to 100%, avoiding letting it discharge and not charging it with temperatures above 35 °C – it is at least possible Don't ruin your phone battery.

  • 1Keep the charge between 20% and 80%
  • 2Do not charge the battery when it is too hot
  • 3Prefer slow charging to fast charging
  • 4Use original chargers and power supplies
  • 5Disable unnecessary services, optimize screen brightness and other tips

Keep the charge between 20% and 80%

Since lithium-ion batteries do not suffer from the so-called “memory effect” there is no need to charge them to 100% and let them discharge to 0%. Indeed, leaving the phone fully charged or completely discharged for a long time could damage the battery capacity and, in the long term, its autonomy. For this reason, one of the best methods to slow down battery deterioration is keep the charge in a range between 80% and 20%including the first charge, which does not have to reach the “canonical” 12 hours as some think. It would be enough to follow this simple one “80-20 rule” to charge and discharge the battery correctly, avoiding “stressing” it by exposing it to voltages that are too low or too high.


Do not charge the battery when it is too hot

Another fundamental precaution to avoid ruining your phone's battery is to Don't charge it when it's too hotas high temperatures can seriously compromise your health by damaging it permanently. Googlefor example, on one of its support pages states:

The battery drains much faster when it is warm, even if you are not using the device. This type of consumption can damage the battery.

Also Apple he is practically of the same opinion for his iPhones. In an article on its official website, in fact, the Cupertino giant recommends:

It is very important to avoid exposing it to temperatures above 35°C, which can permanently damage the battery's capacity and shorten the life of a single charge. When charged in an environment that is too hot, the device can suffer even more damage. And if it is stored at high temperatures, the battery could be irreversibly damaged.

It is also important do not charge the battery if the smartphone has overheated (perhaps due to energy-intensive activities, such as the use of games or video/photo-editing apps), even if the ambient temperature is not high.

Prefer slow charging to fast charging

Even if smartphone manufacturers are optimizing their fast charging systems, to avoid rapid deterioration it can be recommended prefer slow charging where possible. Fast charging, in fact, provides for greater power delivery which physiologically increases the temperatures of the battery pack and, as we have seen in the previous point, the heat can be deadly for this component. Therefore, better limit fast charging to what is strictly necessaryperhaps in real emergency situations.

Use original chargers and power supplies

Since using chargers and power supplies other than those made by the smartphone manufacturer can slow down charging, not adequately charge the battery or even damage it, we can only recommend theuse of original chargers and power supplies.


Disable unnecessary services, optimize screen brightness and other tips

When a certain number of cycles is exceeded (usually after 500 complete charge and discharge cycles), the battery begins to perform less. Extend the battery life as much as possible it means using fewer complete charge and discharge cycles and, therefore, a longer battery life. Here are 10 tips for increasing the battery life of your phone taken from our decalogue (in which we go into them all in depth, point by point).

  1. Prefer Wi-Fi to 4G-LTE or 5G data connection.
  2. Turn off the Always-On feature.
  3. Use low-energy screen settings.
  4. Set the dark theme on OLED displays.
  5. Enable manufacturer optimization features.
  6. Use the device between 0°C and 35°C.
  7. Avoid using apps that are too heavy.
  8. Turn off automatic brightness.
  9. Activate energy saving.
  10. Turn off unnecessary connections with airplane mode.
