Avoid extreme temperatures
Apple devices are designed to perform under a wide range of ambient temperatures; 62° to 72° is the ideal zone. Exposure to ambient temperatures higher than 95° F should be avoided. Using, charging or storing your device in high ambient temperatures could damage the battery irreversibly. Using your device in cold temperatures could cause a decrease in battery life, but is only temporary.

Avoid Charging in Certain Cases
Some cases may cause your device to get hot while charging. If you notice this, remove the device from the case while charging.
Storing Your Device
If you are planning to store your device long term, do not fully charge or discharge your device’s battery. Powering down your device at about 50% will help prevent the battery from falling into a discharge state (which renders it incapable of holding a charge) as well as preventing it from loosing some capacity (which could lead to a shorter battery life). You should store the device in a cool, moisture-free area that is less than 90°F. Every six months your device is in storage, you should charge it to 50%. When you bring it out of storage, it may be in a low-battery state. It may require 20 minutes of charging with the original adapter before if can be used.
Adjust Screen Brightness
Dim your screen or turn on Auto-Brightness. This will help extend your battery life. To dim, open Control Center by swiping up from the bottom of your screen. Drag the brightness slider to the left. To set auto-brightness go to Settings>Display & Brightness and set Auto-Brightness to On. This will automatically adjust your screen to the lighting conditions.
Accessing data using a cellular network uses more power than a Wi-Fi connection. Turning your Wi-Fi on when a connection is available will help to preserve battery life. To turn on Wi-Fi you can either, swipe up to open Control Center, tap the Wi-Fi icon, and log into a Wi-Fi- network, or, go to Settings>Wi-Fi to access a Wi-Fi network.
Enable Low Power Mode
Your iPhone lets you know when your battery life gets down to 20% and then again at 10% and will let you turn on Lowe Power Mode with one tap. If you want to enable it before then, go to Settings>Battery. Enabling Low Power Mode does reduce power consumption until you can fully charge your iPhone, but it also reduces or turns off some features; mail fetch, Hey Siri, background app refresh, automatic downloads and some visual effects.
Monitor Battery Usage
You can manage your device’s battery life by monitoring which apps are using it up. To view your usage, to to Settings>Battery
Background Activity indicates that the battery was used by the app while it was in the background (while you were using another app) You can turn off the feature that allows apps to refresh in the background by going to Settings>General>Background App Refresh. Setting the Mail app to fetch data manually or change the fetch intervals, go to Settings>Mail, Contact Calendars>Fetch New Data

No Cell Coverage indicates that you are in a poor cell coverage area and your device is searching for a better signal. It could also mean you have used your device in a low-signal area. When cell service is not needed, you can switch your phone to Airplane mode by swiping up to open Control Center and tap the Airplane mode icon. You will not be able to make or receive calls while in Airplane mode.
Charging Your Device
It’s always a good idea to make sure your phone has a full charge, especially if you know you won’t be able to charge it for awhile. When using a computer to charge your phone, make sure the laptop is plugged in and powered on. It the computer that it’s connected to is off or in sleep or standby mode, your phone’s battery may drain.
