switching also significantly affects the battery life. What else

for the battery to lose its qualities. If the user notices a
significant loss in the ability to hold the charge, a new battery
should be supplied.
Use only batteries recommended by the Manufacturer.
Do not keep the phone in excessively hot places. High
temperatures might negatively impact both the battery and
the phone.
Never use the battery if it is visibly damaged. Doing so might
cause a short circuit, and might damage the phone. Make
sure to install the battery in accordance with polarity marks.
Leaving the battery in excessively hot or cold places will
reduce the battery life. The recommended storage
temperature range is between 15°C and 25°C. Installing a cold
battery into the phone might cause the phone to malfunction
