how to extend your phone's battery life - battery energy storage system

As mobile phone users, all we want is enough battery life to last a day.
It's frustrating that the older the device, the less power it seems to have.
In fact, the battery life of our phones on any day depends on two key factors: how we use them on a specific day and how we used to use them in the past.
Mobile phone using lithium battery
Ion batteries for energy storage.
In this type of battery, lithium metals and lithium ions go in and out of a single electrode, causing them to physically expand and shrink.
Unfortunately, these processes are not completely reversible and the battery loses its charging capacity and voltage as the charging and discharge cycles increase.
Worse, the electrolyte (
Conductive liquid)
During these cycles, the electrodes connected to the electrodes also degrade.
The ability of lithium-
Ion batteries that store charge depend on how much they degrade.
This means that there is a connection between the way we handle the device today and the charging capacity available in the future.
With a few simple steps, users can minimize this degradation and extend the life of their devices.
Discharge control of typical lithium battery
The cell phone for lithium-ion batteries should be 80% of the charging capacity after retaining 300-
500 charge/discharge cycle.
However, the battery rarely produces this level of performance, and the charging storage capacity is sometimes reduced to 80% levels in 100 cycles.
Fortunately, we can extend the battery capacity in the future by limiting the battery discharge of the mobile phone.
Since most battery degradation occurs during deep discharge/charging cycles, it is best to limit battery discharge in any one cycle before recharging again.
As it happens, we do have batteries on our devices.
The management system can reduce the damage caused by excessive charging. if the battery is too low, the system will automatically turn off.
Nevertheless, in order to maximize the battery capacity in the future, we should completely avoid the 0% battery mark, and at the same time, if these batteries are stored for a long time to avoid deep discharge, also keep these batteries at least partially charged.
Extended charging times many mobile devices today have a quick charging option that users can charge in minutes instead of hours.
It is convenient when we are in a hurry, but it should be avoided. Why?
Because charging the battery too fast will reduce the storage capacity of the battery.
Physically, lithium metal and lithium ion in lithium-
The ion battery is a slow process.
Therefore, charging at a lower rate can achieve a more complete shuttle, thus increasing the charging capacity of the battery.
For example, charging the phone in five minutes compared to the standard two hours can reduce the battery capacity of the charging cycle by more than 20%.
Fortunately, for most parts of the country, the annual temperature in Australia is between 0 °c and 45 °c.
This is the exact range of lithium-
Ion batteries can be stored to keep the best for a long time
Long-term charging capacity.
Below 0 °c, due to the limited movement of lithium metals and lithium ions in the electrode and through the electrolyte, the amount of electricity available in the battery system is reduced.
At more than 45 °c, the amount of electricity available actually increases compared to the lower temperature, so in hotter conditions you can get more "juice" from the battery ".
However, the degradation of the battery is also greatly accelerated at these temperatures, so the ability of the battery to store charge is reduced for a long time.
Therefore, for a long time, especially in the summer, when the surface temperature rises above 70 °c, the phone should be away from direct sunlight. Use battery-
Save mode Aaron Carroll and Gernot Heiser from Data61 analyze the power consumption of different smartphone components in a series of typical scenarios.
They concluded that there are some simple software and hardware strategies that can be used to maintain battery life.
• Reduce the brightness of the screen.
While maintaining full functionality, the easiest way is to reduce the brightness of the screen.
For mobile phones and other devices with organic LEDs (OLED)
Display, you can also view it using the "lights in the dark" option.
Turn off the cellular network or limit the call time.
The connection to the cellular network uses the global mobile communication system (GSM)module.
GSM is the main energy source.
Consuming components in the phone, so it is beneficial to turn off completely or at least limit the call time. • Use Wi-Fi, not 4G. With Wi-
40% reduction in Fi power
Internet browsing, shutting down cellular data and using Wi-
Fi will help with your battery life.
Limit video content.
Video processing is one of the most powerful features
Consumer operations on mobile devices.
Turn on smart battery mode.
All modern mobile devices have smart battery saving modes (
For example, Android has power saving mode and iOS has low power consumption mode).
These software functions modify the central processor (CPU)
Reduce energy consumption with different applications, screen brightness, notifications, and various hardware options.
• Use aircraft mode.
GSM, Wi-is usually disabled in this mode-
The Fi, Bluetooth and GPS features on your device.
When all of these auxiliary functions are turned off, the device will use only 5% of its usual energy consumption as the screen is turned off.
In contrast, simply leaving your device idle still allows you to use more than 15%.
Improving the availability of cell phones requires a combination of limiting the use of power supplies
And handle mobile devices to maximize the charging capacity and minimize battery degradation.
By adopting these simple strategies, users can extend their battery life by more than 40% in any day, while maintaining a more consistent battery capacity throughout the service life of the device.
