Far from extreme temperature
Your equipment in a wide temperature range can do well, between 16 ° C to 22 ° C (62 ° F to 62 ° F) is the ideal temperature zone. It is especially important to make the equipment to avoid environmental temperature above 35 ° C (95 ° F), or may be permanent damage to the battery capacity. In this case, your battery will not be able to power your device for a long time after it is charged. Charging equipment in high temperature can further damage the equipment. Even storing a battery in a high temperature environment can cause irreparable damage. When using devices in very cold environments, you may find that the battery life is reduced, but this is only temporary. When the battery temperature returns to normal operating range, its performance will return to normal.
Remove some protective shells when charging
When you charge the device in some protective shell, it can generate too much heat, which can affect battery capacity. If you find that your device is heating up, please remove the protective shell. For the Apple Watch Edition series, please ensure that the magnetic charge meter box is open.
Please keep half of the battery when stored for long time
If the device is not used for a long time, there are two key factors that affect the overall operation of the battery: the ambient temperature and the percentage of the battery that is charged before a power outage is stored. Therefore, we recommend the following:
Do not fully charge or discharge completely, the equipment charge should be about 50%. If you store the device in a completely depleted battery, the battery may fall into a deep discharge, causing no recharging. On the contrary, if you store fully charged devices for a long time, you may lose some of your battery capacity and shorten the battery life.
Turn off the power of the device to avoid additional battery use.
Put equipment in a cool and not wet environment, the temperature is lower than 32 ° C (90 ° F).
If you plan to store your device for more than six months, you should charge up to 50% of your battery every six months.
Depending on how long the device is stored, it may be in a low battery state when it is used for a long time. To re-use it, you may need to charge it for 20 minutes using the original power adapter.
No matter how you use the device, you can save power in two simple ways: adjust your screen brightness and use a wireless Internet connection.
Dim the screen brightness or turn on the automatic brightness adjustment function to prolong battery life.
To dim the brightness, swipe from the bottom of any screen to open the "control center" and drag the brightness slider to the left.
"Automatic brightness adjustment" can adjust the screen brightness automatically according to the light condition. To activate this function, go to "set" > "screen and brightness" and turn on "automatic brightness adjustment".
When you use the device to get data, the wireless network is much more power-efficient than the cellular network, so it keeps the wireless network open. There are two ways to start a wireless network:
Swipe up to open the "control center", light up the wireless network icon, and then log into the wireless network.
Go to "set" > "wireless LAN" to connect to the wireless network.
Open low power mode
With iOS 9's low-power model, it can easily extend battery life when the iPhone is low. Your iPhone will be notified when the battery is about 20% of the time, and again when the battery remains 10%, you can start the low-power mode by simply clicking on it. Alternatively, you can enter the "Settings" > "battery" to open the mode. Low power mode will reduce screen brightness, optimize device performance, and reduce system animation as much as possible. The app will stop loading the data while the app is running in the background, and the functions of AirDrop, iCloud synchronization and continuous connectivity will also be stopped. You can continue to use major functions, such as answering phone calls, sending and receiving emails and messages, and connecting to the Internet. When your phone is recharged, the low-power mode will automatically shut down.
Activate the power supply computer to charge the equipment
When you use a computer to charge iOS devices via USB, make sure your computer is plugged in and started. If your device is connected to a computer that is shut down, sleep or standby, the battery of the device may run out.
Will the charging line be pulled out after full charge?
The battery is full of unplug and does not charge the battery.
