The people take care of gadgets and battery life and the amount of the time the device runs, it needs to be recharged. Some users find this aspect crucial when looking for a new device.  Everyone knows that battery endurance is not enough. The large resolution screen, multicore CPUs and actively web surfing rapidly exhaust the battery power, it confines to keep the charger around. 

The engineer wants to add extra millimetres to the battery size and increase its endurance too much about the gadget design. The engineer keeps on conserving battery power. Now, the manufacturers largely use lithium rechargeable batteries. 

What is a Lithium rechargeable battery? 

Lithium rechargeable battery is a special type of electrical battery, widely used in modern gadgets. Such batteries are commonly used in all cell phones, smartphones, notebooks, digital photo cameras, and camcorders. The first lithium battery was produced in 1991 by Sony Corporation. There are about 600 recharges cycles available for the lithium-ion- battery. 80% of the battery is depleted. The battery is recharged every day. The battery cycle life lasts for 2 years. 

Lithium-polymer rechargeable battery (Li-pol) 

The analogue of the lithium-ion battery comes with improved design. The batteries of lithium polymer use polymer substances mixed with lithium conductive filling agents. The batteries of lithium polymer are widely used in cell phones, digital devices and smartphones. 

You can actively use your battery device power and regularly put the device on the charge. Need to make sure that charging completes 100% each cycle. It prolonged the battery endurance. The scientist “Paul Scherrer '' found that lithium batteries have a memory effect, keeping up battery charge level. 

Regular charging is not recommended, try to evaluate the time, when you put the device on the charging, by the next charging, your battery runs down 10- 20% of the charging level. It is not recommended to charge the battery. Every battery has a self-discharge rate. 

If you miss the moment when the battery discharges to the 0% level and would not connect the charger timely. The battery runs down beyond 0% and gets discharged to absolute zero by itself. When the device is turned off for that time, which is called “deep discharge”. So the accident causes the device to malfunction and the microcontroller and responsible for the charging. It would not initiate the charging process. So, you will have to take the device service centre to launch the battery. Under the worst scenario, people will have to buy a new battery. 

Therefore, I expected to keep the device turned off for a long time. The device battery is provided with some charge in advance. If the battery with 40% of power, charged at the room temperature. 

The battery is run down 4% every year. if the battery was charged was 100% at the room temperature. It will lose 35% at the same time. 

If you travel a lot, the electric power supply is out of reach, the power bank is an essential mobile phone accessory to keep your phone charged up, and the power bank exceeds the capacity of your battery. It is going to drain your backup. Some charging devices receive power from the sun. The complete charging and discharging cycle conducted at least once per month. 

The life cycle of the battery depends upon the depth of the discharge before reaching the following charge. The voltage shortens the battery life as well. Lithium polymer and lithium-ion battery depending on the charging battery. The battery shall be depleted faster between the cycles if the voltage exceeds 4%.

The degradation of the battery components, when the lithium battery is unused for a while. The material is eventually affected by the decoration process. In the two years’ time of the battery. It may loosen up 20% of its capacity. It means you should not stock up the batteries or over economical use them. 

Keep the device away from extreme Temperature: 

The majority of the electronic devices, especially batteries, are not prepared for low and high temperature. Low temperature expedites lithium battery discharge as well as reduces the battery life cycle. The lithium polymer batteries can work continuously in the lower temperature down to -20°C.  The well-known manufacturers always specify the battery normal operating temperature range. 

 Important: The battery is expected to work normally at a low temperature. But it does not mean that the battery may be charged at the low temperature. Low temperature heavily affects the battery charging sensitivity. Optimal charging temperature shall be between 20°C and 26°C.

The operating temperature range of the lithium-polymer and lithium-ion batteries predetermines their capacity.

Please note! A lithium-ion battery is not recommended to be put in the hot environment with the temperature above 60°C. Strong overheating or strong mechanical damage may instigate the battery's explosion or self-ignition of its lithium component.

Do not leave the charging device plugged into the power socket. For the vital safety reasons, you should disconnect the charger from the power socket after the charging is complete. Anyway, this saves on your electricity bill (though not too much, it does), as well as protects you from the short circuit fire.

Keep in mind that all devices have a service life. Batteries are no exception. To keep your slate "alive" as long as possible, study the manufacturer's recommendations for battery conservation.
