Any mobile phone battery irrespective of its model has a specific lifespan, which is specified by the manufacturer in terms of the number of charging cycles before its capacity of charging reduces. Generally, they are affected by temperature and therefore when they are exposed to a higher temperature or more than 300c, the chances of their life getting reduced are higher. So, it is highly recommended to keep the device away from heavy temperatures. You can also look for the sealed lead acid replacements from NuEnergy Storage Solutions.
When charging lithium-ion cell phone batteries, it is better to remove the casing from the device. This is because when the device is charged with the casing, the chances of the device getting heating up is higher, which in turn will reduce the life of its battery.
Some people say that it is better to charge the battery of any mobile device after it is fully drained. But, this is applicable to nickel-cadmium types and when it comes to lithium-ion, it is not necessary to fully discharge the battery before charging it. This is because when the charge reduces too much, it might cause damage to the device.
