iPhone Maximizing Battery Life and Lifespan

Published: Sept 10, 2014

Four weeks ago I asked why does my iPhone 5 take longer to charge than my 4S and the previous iPhone 3G I didn’t my answer to that but came across a lot of advice on prolonging life, battery life, some I know to be inaccurate, others mis interpreted. I also went to the sours and repeat the article below as Apple have an annoying habit of updating their website when their next big things come’s along irregardless to those of us who liver by ‘if it works well why upgrade?’

I’d already culled my apps almost to the essentials at 77 I’m sure there are more to go. 

The surprise in reading Apples advice was switching off the location services. I discovered a number of apps that did not need to know where I am were keeping tabs on my where a bouts. I’d go as far as to say most apps don’t need your location. 

Apparently the selection of apps connecting with their leaders were causing the iPhone to stay ahead of its speed to charge. Indeed recharge time has increased considerably since I minimised location services. For good measure I made sure push notifications were off too. That put pay to a twitter app tweeping at all hours.

From the apple site:

Turn off push notifications. If you receive several notifications every day, this could affect battery life. To disable, go to Settings > Notification Center, choose the app you want to disable, and do the†following:

• Change Alert Style to None.
• Turn Badge App Icon off.
• Turn Sounds off.

Note: New data will be received when you open the app.

Minimize use of location services. Apps that actively use location services, such as Maps, may reduce battery life. You can see which applications have recently used location services by going to Settings > Privacy > Location Services. Apps that recently used your location have an indicator next to the on/off switch. If you do not expect a particular app to use location services, you can disable it by toggling the switch to Off. To completely disable location services on your device, go to Settings > Privacy > Location†Services and switch it to Off.

Eliminate those location services at least have them at a minimum

THE RESULT: Weeks later did it work. Battery life is lasting longer & does recharge faster. Though it  hasn’t reached near full in an hour.

I’ve copied & pasted Apples Advice from their website, as at the date 20th of August 2014, below because as soon as the next big thing, iPhone update comes along Apple update their website and they don’t archive at least I’ve found none to date.

ìBattery life is the amount of time your device runs before it needs to be recharged. ìBattery lifespanî is the amount of time your battery lasts until it needs to be replaced. Maximize both and youíll get the most out of your Apple devices, no matter which ones you own.

Apple software updates often include advanced energy-saving technologies, so always make sure your device is using the latest version of iOS or OS X.

How to update iOS     How to update OS X

Your device is designed to perform well in a wide range of temperatures, with 62∞ to
72∞ F (16∞ to 22∞ C) as the ideal comfort zone. Itís especially important to avoid exposing your device to temperatures higher than 95∞ F (35∞ C), which can permanently damage battery capacity. That is, your battery wonít power your device as long on a given charge. Charging the device in high temperatures can damage it further. Even storing a battery in a hot environment can damage it irreversibly. When using your device in a very cold environment, you may notice a decrease in battery life, but this condition is temporary. Once the batteryís temperature returns to its normal operating range, its performance will return to normal as well.

iPhone, iPad, and iPod work best at 32∞ to 95∞ F (0∞ to 35∞ C). Storage temperature: -4∞ to 113∞ F (-20∞ to 45∞ C).

MacBook works best at 50∞ to 95∞ F (10∞ to 35∞ C). Storage temperature: -4∞ to 113∞ F (-20∞ to 45∞ C).

Charging your device when itís inside certain styles of cases may generate excess heat, which can affect battery capacity. If you notice that your device gets hot when you charge it, take it out of its case first.

If you want to store your device long term, two key factors will affect the overall health of your battery: the environmental temperature and the percentage of charge on the battery when itís powered down for storage. Therefore, we recommend the following:

• Do not fully charge or fully discharge your deviceís battery ó charge it to around 50%. If you store a device when its battery is fully discharged, the battery could fall into a deep discharge state, which renders it incapable of holding a charge. Conversely, if you store it fully charged for an extended period of time, the battery may lose some capacity, leading to shorter battery life.
• Power down the device to avoid additional battery use.
• Place your device in a cool, moisture-free environment thatís less than 90∞ F (32∞ C).
• If you plan to store your device for longer than six months, charge it to 50% every six months.

Depending on how long you store your device, it may be in a low-battery state when you remove it from long-term storage. After itís removed from storage, it may require 20 minutes of charging with the original adapter before you can use it.

Always make sure your device is using the latest version of iOS.

• If you are using iOS 5 or later, see if you need an update. Go to Settings > General > Software Update.
• If an update is available, you can plug your device into a power source and update wirelessly or plug it into your computer and update with the latest version of†iTunes.

Depending on your deviceís settings, it may use battery power for actions performed automatically or in the background ó actions you may not even notice. You can extend your deviceís battery life by adjusting some of these settings. These tips apply to devices running iOS 7 or later.

Keep Wi-Fi on at all times. When using your device to access data, a Wi-Fi connection uses less power than a cellular network ó so connect to a Wi-Fi network whenever one is available. To turn on Wi-Fi, swipe open Control Center, tap the Wi-Fi icon, and log in to a Wi-Fi network. Alternatively, you can go to Settings > Wi-Fi to access a Wi-Fi network.

Adjust brightness. Dim the screen or turn on Auto-Brightness to extend battery life. To dim manually, go to Settings > Wallpapers & Brightness and drag the slider to the left. To return to the default behavior, turn Auto-Brightness off and then on again. When Auto-Brightness is on, your screen adjusts to lighting conditions automatically. To activate it, go to Settings > Wallpapers & Brightness and set Auto-Brightness to On.

Fetch new data less frequently. The more frequently you fetch email or other data, the more battery power your device may use.

• To fetch data manually, go to 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: This global setting applies to all applications that do not support push†services.
• If you receive a lot of email, you can turn off push email to save your battery. Go to Settings > Mail, Contacts, Calendars > Fetch New Data. 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.

Turn off push notifications. If you receive several notifications every day, this could affect battery life. To disable, go to Settings > Notification Center, choose the app you want to disable, and do the†following:

• Change Alert Style to None.
• Turn Badge App Icon off.
• Turn Sounds off.

Note: New data will be received when you open the app.

Minimize use of location services. Apps that actively use location services, such as Maps, may reduce battery life. You can see which applications have recently used location services by going to Settings > Privacy > Location Services. Apps that recently used your location have an indicator next to the on/off switch. If you do not expect a particular app to use location services, you can disable it by toggling the switch to Off. To completely disable location services on your device, go to Settings > Privacy > Location†Services and switch it to Off.

Use Airplane mode in low- or no-coverage areas. Your cellular-enabled device always tries to maintain a connection with a cellular network, which may use more power in low- or no-coverage areas. Turn on Airplane mode to increase battery life in these situations. To turn on Airplane mode, swipe open Control Center and tap the Airplane mode icon. Alternatively, you can go to Settings and set Airplane mode to On. Note that you cannot make or receive calls with Airplane mode on.

Lock your device. Besides offering extra security, locking helps prevent accidental power use. You can also save battery power by setting the Auto-Lock interval so your device turns off more quickly after a period of inactivity. To set the shortest interval, go to Settings > General > Auto-Lock and select 1 Minute.

Minimize automatic iTunes and app downloads. Itís convenient to automatically download purchases from the App Store, iBooks Store, or iTunes Store ó as well as app†updates ó to all your devices. But it can affect battery life. To deactivate Automatic Downloads, go to Settings > iTunes & App Store and scroll to Automatic Downloads. Toggle each appís switch to Off to deactivate this feature.

Minimize Background App Refresh. Background App Refresh allows apps to refresh with new content while youíre using another app. To save battery power, you can turn off this feature. Go to Settings > General > Background App Refresh and toggle the switch to Off to deactivate the feature entirely or select individual apps to turn off.

Make sure your computer is plugged in and powered on when youíre using it to charge your iOS device via USB. If your device is connected to a computer thatís turned off or is in sleep or standby mode, your deviceís battery may drain. iPhone 3G and iPhone 3GS cannot be charged with a FireWire power adapter or FireWire-based car charger.
