iPhone battery tips


Just pay attention and follow some common sense guidelines to extend the battery life and longevity of your iPhone. Most importantly, avoid placing your iPhone in the sun or in a heated car (even in a glove compartment). Heat is the easiest to reduce battery performance.

Terms you need to understand

Battery life indicates the time the iPhone's battery was used before it must be recharged. Battery life indicates the total time the battery is used before it must be replaced.

iPhone temperature band. The optimal temperature for iPhone operation is in the range of 32°F to 95°F. You should store it in an environment from -4°F to 113°F. That is, 0°C to 35°C and -20°C to 45°C are suitable temperatures for running and storing your iPhone. Try to get your iPhone close to the room temperature (22 ° C), which is the best state. View usage status statistics

Know how you use your iPhone and know how long your battery lasts, helping to increase battery life. You can view your iPhone usage status statistics by tapping the Settings icon on the Home screen and selecting General > Usage. Below the usage time after the last full charge you will see two items:

Use: The total time the iPhone has been awake and in use since it was last fully charged. The iPhone is awake when you are on a call, using e-mail, listening to music, browsing the web, or sending or receiving text messages, or when the phone is performing a background task such as automatically checking for e-mail.

Standby: The total boot time of the iPhone since the last full charge, including when the iPhone is asleep.

Upgrade to the latest software

Keep your iPhone up to date with Apple's latest software, as Apple engineers may have developed new ways to optimize battery performance. With iTunes 8.2 or later, you can upgrade your iPhone to the latest software. Connect your iPhone to your computer and select iPhone in the source list. In the summary panel, click "Check for updated items" to see if a new version of the iPhone software is available. Click "Update" to install the latest version.

The way to use jailbreak/unlock is to use the iPhone's friends to be careful, don't just use iTunes to upgrade, once it becomes 3.1.3 (5.12.01), the gods can't do it now...

Optimize your settings

Depending on how you set it up, some features may shorten your iPhone's battery life. For example, the frequency with which you accept emails and the number of email accounts that are set to automatically check will affect battery life. The following tips are for iPhones running iPhone 3.0 or higher and can help you extend battery life.

Reduce the use of location services: Applications that enable location services, such as maps, can reduce battery life. To turn off location services, go to Settings > General >

"Location Services" to set up, or use location services only when needed.

Turn off push notifications: Some apps from the App Store use the Apple Push Notification Service to alert you about new data. These applications that rely heavily on push notifications (such as instant messaging applications) can affect battery life. To turn off push notifications, go to Settings > Notifications and set Notifications to Off. Note that this does not prevent the app from receiving new data when it is turned on. Also, if you don't have any apps that support push notifications, the notification settings will not be displayed.

Reduce the frequency of fetching new data: Some applications, such as Mail, can be set to retrieve data wirelessly at specific time intervals. The higher the frequency of e-mail or other data, the faster the battery will consume. To manually extract new data, on the Home screen, choose Settings > Email/Contacts/Calendars > Capture New Data and tap Manual. To increase the time between captures, go to Settings > Email/Contacts/Calendars > Capture New Data and tap Hourly. Please note that this is a pass-through setting for all applications that do not support push services.

Turn off push mail: If you use a push mail account such as Yahoo! or Microsoft Exchange, turn off push mail when you don't need it. Go to Settings > Email/Contacts/Calendars > Capture New Data and turn the push off. The information sent to your push email account will then be received according to the access settings you have set, and will not be received as soon as it arrives.

Reduce the number of email accounts that are automatically checked: Avoiding letters that receive too many email accounts can help you save power. This can be done by deactivating or deleting an email account. To turn off an account, go to Settings > Email/Contacts/Calendar, select an email account, and then close it. To delete an account, go to Settings > Email/Contacts/Calendar, select an email account, and tap Delete Account. Reduce the use of third-party applications: Excessive use of applications such as games that make screens dark or closed, or applications that use location services can reduce battery life.

Turn off Wi-Fi: If you rarely use Wi-Fi, you can turn it off to save power. Go to Settings > Wi-Fi and set Wi-Fi to Off. Please note that if you frequently use the iPhone to browse the web, using a Wi-Fi network can extend battery life compared to cellular data networks.

Turn off Bluetooth: If you rarely use a Bluetooth headset or a car kit, you can turn off Bluetooth to save power. Go to Settings > General > Bluetooth and turn Bluetooth off.

Use airplane mode in areas with poor signal or no signal coverage: Since the iPhone will always try to stay connected to the cellular network, it will consume more power in areas with poor signal or no signal coverage. In this case, turning on airplane mode can extend battery life, however, you will not be able to receive or make calls. To turn on airplane mode, go to Settings and turn Airplane mode on.

Adjusting the brightness: Dimming the screen is another way to extend battery life. Turn down the brightness by going to Settings > Brightness and dragging the slider to the left. In addition, turning on Auto Brightness allows the screen brightness to adjust to the brightness of the field environment. Go to Settings > Brightness and turn the auto brightness on.

Turn off the equalizer: Applying the equalizer settings while playing a song will reduce battery life. To turn off the equalizer, go to Settings > iPod > EQ to close it. Please note that if you add the equalizer directly to the song in iTunes, you must set the EQ to "Flat" on the iPhone to turn off the equalizer, as the iPhone does not change your iTunes settings. To make this setting, go to Settings > iPod > EQ and tap Flat.

Turn off 3G: Use 3G cellular networks to load data faster, but it also reduces battery life, especially in areas with limited 3G coverage. To turn off 3G, on the home screen choose Settings > General > Network and set Enable 3G to Off. You can still receive and make calls in these ways with an EDGE or GPRS network, or you can use a cellular data network. (For the majority of domestic GSM friends, turn off 3G)

Lock your iPhone

Obviously, you should lock it when you are not using it. While locked, you can still receive calls and receive text messages, but it won't work if you touch the screen. To lock your iPhone, tap the Sleep/Wake button. You can also set the auto-lock time interval to have your iPhone shut down more quickly after a period of inactivity. To set up auto lock, go to Settings > General > Autolock and set a shorter time interval, such as one minute.

Use the iPhone often

To properly maintain the lithium battery, the electrons must be kept flowing occasionally. Please ensure that you have at least one charge cycle per month. (The battery is fully charged and the battery is completely used up).
