The screen resolution of smartphones is getting higher and higher, and the CPU performance is getting stronger and stronger. However, the battery life has not improved for many years. It is very good to use a mobile phone that can last a whole day under heavy use.
Many people are used to plugging the phone into the charger the night before, charging for one night until dawn, and getting up 100% of the electricity after getting out.
Although today's smartphones have a well-established overcharge protection mechanism to prevent damage to the battery, they do not control battery heating. Especially if you put your phone under the pillow or charge it on the bed overnight.
Phonearena today published a discussion of the relationship between cell phone charge percentage, temperature and battery life decay.
According to research data from BatteryUniversity, 40% of the battery is charged at 40 °C, and the battery can retain 85% of its life after one year. It has been charged to 100%, leaving only 65% ​​of life after one year. Simply put, the higher the temperature, the higher the charge ratio (for example, to 100%), the faster the battery life decays.
See the table below for details:
It is used for continuous level measurement. The signal transmitted by its sensor is collected by the receiving system after being reflected by the target, and the distance of the target is determined by measuring the reflection running time. Then the level distance is converted into an output signal and output as a measured value.
The liquid level radar is applicable to the continuous non-contact liquid level measurement of liquid cargo tanks and overflow tanks of oil tankers and chemical carriers. It is also applicable to the liquid level monitoring of other oil tanks, towers, tank equipment and oil production platforms. Its measurement results are not affected by medium replacement, temperature change and gas or steam coverage.
