How to Extend the Battery Life of an iPad

    How to Extend the Battery Life of an iPad

    Just as with an iPhone or iPod Touch, the battery life of your iPad will be shorter during heavy use. However, there are some measures you can take to keep your device on and active for hours of enjoyment, and this article explains what you can do to lengthen the battery life

    1.Turn off Wi-Fi and cellular data (iPad + 3G) settings. Your iPad drains battery power when searching for and attempting to connect to the nearest Wi-Fi or cellular network tower, so if you're not planning on using Safari or apps that require these features, shut them off.

        * Go to "Settings", "WiFi option" or "Cellular", and tap the off switch.

    2.Turn off or decrease the timing for data fetching. Data that are updated regularly include email notifications and RSS feed.

        * Go to "Settings". Tap on "Mail, Contacts, Calendars" and go to "Fetch New Data". Tap "Manually".
        * Alternately, tap "Hourly" to increase the fetching interval.

       
    3.Turn off Push notifications. The usefulness of this step depends on how many emails or IM+ you usually receive; if you get a lot, this step is probably worth using as this can deplete battery life.

     * Go to "Settings", "Mail, Contacts, Calendars" and "Fetch New Data". Turn off Push.
    4. Tone down the brightness. It goes without saying that the brighter the screen, the more battery power your iPad consumes. Turn down the brightness to a setting that looks right.

        * Go to "Settings", then "Brightness & Wallpaper".
        * Select "Auto Brightness", which will allow the iPad to adjust brightness depending on the brightness of your location; or
        * Drag the slider to the left to lower the default screen brightness. 25 percent to 30 percent brightness should be sufficient for daytime use, and for most people, should also work for nighttime.


     5.Turn off the sound effects. Sounds can cause the battery to deplete quickly if they are frequent and as they are activated by default, they will sound whenever you receive notifications or when pressing buttons for the on-screen keyboard.

        * Go to "Settings", "General", and "Sounds". There are five different options on the equalizer to "Increase/Decrease". Or, you can switch to "On/Off" if preferred. Obviously, disabling the lot would decrease the battery usage by sounds.

    6.Turn off location services. Active use of maps and other location services will drain battery life. If left on, Maps updates continuously, something that you don't need draining your battery.


    7.# Avoid frequent use of 3D or graphic heavy apps. Sure, BrickBreaker HD looks great in high-definition, but playing for long periods of time drains battery life like a hose.
    #8Switch on Airplane Mode if you have an iPad + 3G. It blocks all of the iPad's wireless signals and will increase battery life. In areas where 3G is patchy or weak, this could drain the battery even more, so it's a very good idea to turn it off in such a situation.
    #9Keep the iPad away from temperature extremes. Extreme high or low temperatures can cause the battery life to decrease. Keep the iPad environment between 32ºF and 95ºF(0ºC and 35ºC).[2]

        * Be careful of using an iPad case when charging the battery, as this can prevent adequate ventilation, increasing the temperature of the iPad and potentially damaging the battery (charging releases heat).

    #10Keep your software up-to-date at all times. Apple recommends updating regularly because engineers look for new ways to optimize battery performance and when they find any ways, they pass these on via software updates.
    #11Switch on the auto-lock feature. This means that your iPad will turn off after a set period of time if left inactive.

        * Go to "Settings", "General", and tap on "Auto Lock". Set the interval to a short space of time, such as one minute.

        * Contrary to popular belief, shutting off the iPad when not in use and turning it back on when you do will more often then not, especially in short periods of time, waste battery life because of the energy the iPad takes up trying too boot up/shut down.
        * Always charge your device before leaving home, especially on long trips. Bring the charger with you if you are going away overnight, or for an extended period of time. While the iPad battery is slated to last up to 10 hours, frequent use will shorten this time dramatically.
        * Perform a monthly battery calibration. Drain the battery completely, then charge it 100 percent.
        * Charging batteries in a warm environment reduces the amount of charge accepted by the batteries and lowers the voltage that the batteries are charged to. So charge your iPad in a cool place to get the maximum charge to begin with.
        * Understand the difference between battery life and battery lifespan. Battery life refers to the time before a battery requires recharging; battery lifespan refers to the time a battery lasts before it needs to be replaced.
        * Apple states that normal battery life for surfing the internet using WiFi, playing music or watching videos is up to 10 hours, while surfing the internet using a 3G network should be up to about 9 hours.
        * Repeatedly draining your battery completely (called a “deep discharge”) can shorten the life span of the battery. So, if you use your iPad until the battery fails, you will get more use of your iPad on this particular charge, but you will reduce the number of times you can recharge your iPad’s battery. (Most lithium batteries can be recharged about 500 times. If you are a heavy iPad user, that could be less than two years.)

How To Extend iPhone 4 Battery Life?

    How To Extend iPhone 4 Battery Life?

    Paying attention to just a few commonsense pointers will pay off with a longer battery lifespan and battery life for your iPhone. The most important thing is to keep your iPhone out of the sun or a hot car (including the glove box). Heat will degrade your battery’s performance the most.
    Some Terms You Need to Understand

    “Battery life” means the time your iPhone will run before it must be recharged. “Battery lifespan” means the total amount of time your battery will last before it must be replaced.

    Awareness of how you use your iPhone and knowing how long your battery typically lasts can help you improve its battery life. You can view your iPhone usage statistics by tapping the Settings icon on the Home screen and choosing General > Usage. Under the “Time since last full charge” heading you’ll see two items:

    * Usage: Amount of time iPhone has been awake and in use since the last full charge. The phone is awake when you’re on a call, using email, listening to music, browsing the web, or sending and receiving text messages, or during certain background tasks such as auto-checking email.
    * Standby: Amount of time iPhone has been powered on since its last full charge, including the time the phone has been asleep.

    Optimize Your Settings


    Depending on how they are configured, a few features may decrease your iPhone battery life. For example, the frequency with which you retrieve email and the number of email accounts you auto-check can both affect battery life. The tips below apply to an iPhone running iPhone 3.0 or later software and may help extend your battery life.

        * Minimize use of location services: Applications that actively use location services such as Maps may reduce battery life. To disable location services, go to Settings > General > Location Services or use location services only when needed.
        * Turn off push notifications: Some applications from the App Store use the Apple Push Notification Service to alert you of new data. Those applications that extensively rely on push notifications (such as instant messaging applications) may impact battery life. To disable push notifications, go to Settings > Notifications and set Notifications to Off. Note that this does not prevent new data from being received when the application is opened. Also, the Notifications setting will not be visible if you do not have any applications installed that support push notifications.
        * Fetch new data less frequently: Applications such as Mail can be set to fetch data wirelessly at specific intervals. The more frequently email or other data is fetched, the quicker your battery may drain. To fetch new data manually, from the Home screen choose Settings > Mail, Contacts, Calendars > Fetch New Data and tap Manually. To increase the fetch interval, go to Settings > Mail, Contacts, Calendars > Fetch New Data and tap Hourly. Note that this is a global setting and applies to all applications that do not support push services.
        * Turn off push mail: If you have a push mail account such as Yahoo!, MobileMe or Microsoft Exchange, turn off push when you don’t need it. Go to Settings > Mail, Contacts, Calendars > Fetch New Data and set Push to Off. Messages sent to your push email accounts will now be received on your phone based on the global Fetch setting rather than as they arrive. If the global Fetch setting is set to Manually, you will not be able to locate your iPhone using the MobileMe Find My iPhone feature.
        * Auto-check fewer email accounts: You can save power by checking fewer email accounts. This can be accomplished by turning off an email account or by deleting it. To turn off an account, go to Settings > Mail, Contacts, Calendars, choose an email account, and set Account to Off. To remove an account, go to Settings > Mail, Contacts, Calendars, choose an email account, and tap Delete Account.
        * Minimize use of third-party applications: Excessive use of applications such as games that prevent the screen from dimming or shutting off 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. Note that if you frequently use your iPhone to browse the web, battery life may be improved by using Wi-Fi instead of cellular data networks.
        * Turn off Bluetooth: If you rarely use a Bluetooth headset or car kit, you can turn off Bluetooth to save power. Go to Settings > General > Bluetooth and set Bluetooth to Off.
        * Use Airplane Mode in low- or no-coverage areas: Because your iPhone always tries to maintain a connection with the cellular network, it may use more power in low- or no-coverage areas. Turning on Airplane Mode can increase battery life in these situations; however, you will be unable to make or receive calls. To turn on Airplane Mode, go to Settings and set Airplane Mode to On.
        * Adjust brightness: Dimming the screen is another way to extend battery life. Go to Settings > Brightness and drag the slider to the left to lower the default screen brightness. In addition, turning on Auto-Brightness allows the screen to adjust its brightness based on current lighting conditions. Go to Settings > Brightness and set Auto-Brightness to On.
        * Turn off EQ: Applying an equalizer setting to song playback on your iPhone can decrease battery life. To turn EQ off, go to Settings > iPod > EQ and tap Off. Note that if you’ve added EQ to songs directly in iTunes, you’ll need to set EQ on iPhone to Flat in order to have the same effect as Off because iPhone keeps your iTunes settings intact. Go to Settings > iPod > EQ and tap Flat.
        * Turn off 3G: Using 3G cellular networks loads data faster, but may also decrease battery life, especially in areas with limited 3G coverage. To disable 3G, from the Home screen choose Settings > General > Network and set Enable 3G to Off. You will still be able to make and receive calls and access cellular data networks via EDGE or GPRS where available.
    Lock Your iPhone

    It may seem obvious, but you should lock your iPhone when you aren’t using it. You will be able to receive calls and text messages while it is locked, but nothing happens if you touch the screen. To lock iPhone, press the Sleep/Wake button. You can also set the Auto-Lock interval so your iPhone will turn off more quickly after a period of inactivity. To set Auto-Lock, go to Settings > General > Auto-Lock and set the interval to a short time, such as 1 minute.
    Use iPhone Regularly

    For proper maintenance of a lithium-based battery, it’s important to keep the electrons in it moving occasionally. Be sure to go through at least one charge cycle per month (charging the battery to 100% and then completely running it down).

    Charging Tips

    iPhone 3G and iPhone 3GS cannot be charged with a FireWire power adapter or FireWire-based car charger. Make sure your computer is on while charging iPhone via USB. If iPhone is connected to a computer that’s turned off or is in sleep or standby mode, the iPhone battery may drain.
    Maximum Battery Life1

    iPhone 4 offers up to 7 hours of talk time on 3G, 14 hours of talk time on 2G, 6 hours of Internet use on 3G, 10 hours of Internet use on Wi-Fi, 10 hours of video playback, or 40 hours of audio playback on a full charge at original capacity. In addition, iPhone 4 features up to 300 hours of standby time.
    Charge Cycles
    A properly maintained iPhone battery is designed to retain up to 80% of its original capacity at 400 full charge and discharge cycles. You may choose to replace your battery when it no longer holds sufficient charge to meet your needs.
    Let It Breathe

    Charging your iPhone while in certain carrying cases may generate excess heat, which can affect battery capacity. If you notice that your iPhone gets hot when you charge it, take it out of its case first.
