Please read the manual of the specified charger for the charging method.
Do not damage the power cord by bending, twisting, or heating. Do not
use the plug if it is loose as it may cause electric shock or fire.
Do not place any heavy items on the power cord. Do not allow the power
cord to be crimped as it may cause electric shock or fire.
Unplug the power cord prior to cleaning your phone, and clean the power
plug pin when it's dirty. When using the power plug, ensure that it's firmly
connected. If not, it may cause excessive heat or fire. If you put your
phone in a pocket or bag without covering the receptacle of the phone
(power plug pin), metallic articles (such as a coin, paperclip or pen) may
short-circuit the phone. Always cover the receptacle when not in use.
Recharge the battery after long periods of non-use to maximize battery
life. Battery life will vary due to usage pattern and environmental
conditions.
Please use only an approved charging accessory to charge your LG
phone. Improper handling of the charging port, as well as the use of an
incompatible charger, may cause damage to your phone and void the
warranty.
Never store your phone in temperatures less than -4°F or greater than
122°F.
The charging temperature range is regulated between 32°F (0°C) and

temperature range. Charging outside this range might cause excessive
heat generation, serious battery damage, and deterioration of battery's
characteristics and cycle life.
Do not use or leave the phone in direct sunlight or in a car heated by
sunshine. The battery may generate excessive heat, smoke, or flame. It
also might cause deterioration of battery's characteristics or cycle life.
