Battery care
• Your device is powered by a rechargeable battery. When the power is
weak, please charge the battery. In order to extend the lifespan of the
battery, use all the battery's power before recharging.
• Unplug the charger from the electrical plug and the device when not in
use. Do not leave the battery connected to a charger more than a week.
Overcharging may shorten its lifespan.
• Extreme temperatures can affect the ability of your battery to charge.
Battery needs the fit temperature. If the surrounding temperature is over
40°C, the battery cannot be charged.
• Use the battery only for its intended purpose. Never use any charger or
battery that is damaged.
Do not short-circuit the battery. Accidental short-circuiting can occur
when a metallic object such as a coin, clip, or pen causes direct
connection of the positive (+) and negative (-) terminals of the battery.
(These look like metal strips on the battery.) Short-circuiting the
terminals may damage the battery or the connecting object.
• Leaving the battery in hot or cold places, such as in a closed car in
summer or a freezer in winter conditions, will reduce the capacity and
lifetime of the battery. Always try to keep the battery between 59°F and
77°F (15°C and 25°C). A hot or cold battery may not function temporarily,
even when the battery is fully charged.
• Battery performance is particularly limited in temperatures below
freezing.
• Do not dispose of batteries in a fire! Dispose of batteries according to
local regulations. Please recycle when possible. Cellphones are not
considered household waste.
Mobile phone maintenance
• Keep the device dry. Precipitation, humidity, and all types of liquids or
moisture can contain minerals that will corrode electronic circuits. If
your device does get wet, remove the battery and allow the device to dry
completely before replacing it.
• Do not use or store the device in dusty, dirty areas. Its moving parts and
electronic components can be damaged.
• Do not store the device in hot areas. High temperatures can shorten the
life of electronic devices, damage batteries, and warp or melt certain
plastics.
• Do not store the device in cold areas. When the device returns to its
normal temperature, moisture can form inside the device and damage
electronic circuit boards.
• Do not attempt to open the device other than as instructed in this guide.
• Do not drop, knock, or shake the device. Rough handling can break
internal circuit boards and fine mechanics.
• Do not use harsh chemicals, cleaning solvents, or strong detergents to
clean the device.
• Do not paint the device Paint can clog the moving parts and prevent
