How to increase your iPhone's battery lifespan

The most common question about the iPhone since I started working as a technician at Lovefone is how to increase the iPhone battery's lifespan. Well, it mostly depends on the way we use our phones. Sadly, there is no special formula that can transform your ordinary battery into a super battery but there are still a few tips about how to increase your iPhone battery that you might find useful. Paying attention to just a few common sense pointers will pay off with both a longer battery lifespan and a battery life for your iPhone. One tip is to turn off your wifi when you don't need it, but there are so many of us that can’t live without internet, and so turning wifi on and off every time you wanna go online is just not gonna work. So I thought I’d share some more tips and i'm sure everybody will find the right way for them to increase the battery lifespan. The most important thing is to keep your iPhone out of the sun or a hot car. Heat will degrade your battery’s performance the most.

Lifespan – what does this mean?

The ‘lifespan’ of the battery refers to the number of times it can be recharged before it must be replaced. The batteries on the iPhone and iPod touch slowly lose the ability to hold a charge after numerous recharge cycles. For example, after 400 full discharge/recharge cycles these batteries are able to store 80% of their original capacity. This percentage decreases with further recharge cycles.The longer you go between charges, the fewer charges you’ll have over time, and the longer your battery will last. After a while you may decide to replace your battery when it no longer holds sufficient charge to meet your needs.


Using your iPhone regularly helps to ensure optimal battery life. Apple recommends that you go through at least one full charge cycle per month, which means charging your iPhone to 100% and then draining the battery completely before the next recharge. During charging, make sure your computer is turned on. If the iPhone is connected to a computer that is off or is in sleep mode, the battery will not charge and may drain. If you notice your iPhone getting excessively warm during charging and you are using an iPhone case, remove the case to let the phone breathe.

Update to the latest software

Apple recommends that you make sure your iPhone has the latest version of iOS, as their engineers may find new ways to optimize battery performance. Using the latest version of iTunes, you can update your iPhone with the latest software. Connect your iPhone to your computer, then select iPhone in the Source List. In the Summary pane, click Check for Updates to see if there’s a new version of the iPhone software available. Click Update to install the latest version. If your iPhone is running iOS 5 or later, you can also wirelessly update it to the latest version by going to Settings > General > Software Update and following the onscreen instructions.

Optimize your settings

Depending on how they are configured, several 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 iOS 5.0 or later and may help extend your battery life.

A Few tips to increase your battery lifespan

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. 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! 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.

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.

Turn off wifi

If you rarely use wifi, 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 wifi 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 the EQ on the iPhone to Flat in order to have the same effect as Off because the iPhone keeps the same setting as iTunes. Go to Settings > iPod > EQ and tap Flat.

Hopefully everybody looking to extend the lifespan of their battery will find two or three tips that will help. I don't use many of them myself but, hey, I work for Lovefone where we can replace your iPhone battery at the end of its useful life, so that's my greatest tip!
