This post is aimed at helping users of iPhone 6s Plus (#iPhone6splus) learn how to properly manage their device and make the most of such a hefty Apple handset. Read on to learn how to maximize your iPhone’s battery life and make your device work at its ultimate performance.


The procedures we demonstrate in this content are purposely elucidated in order to address the needs of those who are still trying to get acquainted with the new iOS platform, especially those who have just made a switch from Android. So let’s cut to the chase…

Understanding Apple iPhone 6s Plus Battery Technology

Your iPhone 6s Plus is schemed with a non-removable internal battery that utilizes a rechargeable lithium-ion technology, offering ultimate performance to your device.

Apple’s lithium-ion batteries weigh lesser, last longer, and charge more efficiently than the older battery types. This new battery technology utilizes fast charging to quickly charge the battery up to 80 percent of its capacity and then switches to slower trickle charging mode to ease the electrical current, thus extending your iPhone’s battery lifespan.

Note: The amount of time it takes to reach the first 80 percent may vary depending on your phone settings.

To get the most out of your iPhone, you need to consider two important factors — the battery life and battery lifespan.

Let’s know their distinctions to understand them better:

  • Battery life refers to the amount of time your iPhone runs before it needs to be recharged.
  • Battery lifespan refers to the amount of time your phone’s battery lasts until it needs to be replaced.

While this new iPhone is already fortified with a great battery life, it doesn’t denote it would stay in the same eminence especially as it ages. Read on to learn more about your iPhone’s battery technology and get the most out of it throughout its lifespan and beyond.

Proper Charging and Regular Monitoring your iPhone 6s Plus Battery

Maximizing battery performance with your device begins with proper charging and monitoring of its battery status in regular basis.

Here’s how to access the battery status menu on your device:

  • To check how much of your phone’s battery life is used by each application, navigate to the Settings menu, tap Battery->Usage, and then tap Battery Usage.
  • To show the percentage of the remaining battery charge, navigate to your iPhone Settings-> Battery-> Usage.

And here’s how to properly charge your device:

The proper way of charging your iPhone 6s Plus battery is by connecting it to a power outlet using the included cable and USB power adapter. This is a highly-recommended way of charging.

If a power outlet is not available, then you can also charge your iPhone by connecting it to a computer. Just connect it to a compatible USB port (preferably high-power USB 2.0 or 3.0 port), on your computer.

  • The battery icon serves as your hint as to when to charge your device. Located in the upper-right corner of the display, this icon indicates the battery level or charging status (while in charging state). This icon will tell you if your iPhone is very low on power through an image of a nearly depleted battery. If you see this image, then you need to charge your iPhone for up to 10 minutes prior to use it again.
  • If you want to view the battery percentage, you can navigate to your iPhone Settings->tap Battery, and then toggle the Battery Percentage switch to turn the feature on or off.

When charging your iPhone to a computer, be sure to keep the computer turned on or in active state. There’s a chance that your iPhone battery may die completely instead of charging, if it’s connected to a computer that is in sleep or standby mode, or turned off.

Important Notes:

  • The screen may go blank for up to two minutes before the low-battery image shows, if your iPhone is extremely low on power.
  • It could take longer for your iPhone to charge when syncing or using it while charging.
  • Rechargeable batteries like those with the 6s Plus have limited charge cycles. This means you need to replace these batteries eventually.

More Helpful Tips for Extensive Battery Life and Better Device Performance

Other than regular monitoring and proper battery charging, you can also perform the following methods to conserve battery power on your iPhone 6s Plus.

  1. Keep your iPhone software updated to the latest version available. Software updates released by Apple often features advanced energy-saving technologies to enhance performance and functionality of a device. To ensure you don’t miss out on the latest features, it is recommended to keep your device software up to date.

Note: Be sure to create a backup of your important files first either via iCloud or iTunes before you start updating your device software.

iOS updates can be obtained wirelessly or through iTunes. To update wirelessly, follow these steps:

  • Plug in your iPhone to a power source.
  • Connect to the Internet via Wi-Fi.
  • Tap Settings.
  • Select General.
  • To view available updates, tap Software Update.
  • If an update is available, tap Download and Install.
  • If prompted with a message to temporarily remove apps to free up some space for the update, tap Continue or Cancel.
  • Follow the onscreen instructions to complete the process.
  1. Keep your iPhone away from extremely hot temperatures. Just like any other mobile devices, the iPhone 6s Plus also has limits in terms of ambience temperature. As Apple recommends, avoid exposing your iPhone to ambient temperatures above 35 degrees Celsius as it can cause permanent damage to the battery capacity of your device. Charging the iPhone in high ambient temperatures or storing the battery in a hot area can also damage it further.

On the other hand, a slight decrease in battery life may occur if you are using your phone in a very cold environment. This condition however is just temporary, so its performance will go back to normal once the battery’s temperature returns to its normal operating range.

  1. Remove phone casing while charging. Some cases will generate excess heat when you charge the device when it’s inside them. This can also affect the battery capacity. An indication that you need to remove the case is when your device gets hot when you charge it.
  2. Keep it half-charge if unused for long. Apple likewise recommends to store your iPhone half-charge if you won’t use it long term. This means you need to keep the device’s battery charge to around 50 percent. Keep in mind that the overall health of your battery will be affected by the environmental temperature and the percentage of charge on the battery when it’s powered down for storage.

Storing the device for long period with a fully charged battery could cause the battery to lose some capacity and shorter battery life. Conversely, storing it when the battery is completely discharged or empty could cause the battery to fall into a deep discharge state, risking it to become incapable of holding a charge.

To avoid additional battery use, just power down your device.

  1. Optimize your device settings. Aside from heeding the do’s and don’ts on battery charging, optimizing your settings can also help stretch your iPhone’s battery life and lifespan. For example, adjusting the phone’s screen brightness and manage the use of Wi-Fi feature can help preserve or extend battery life.
  • To make the screen a bit dimmer, swipe up from the bottom of any screen to access the Control Center. Once you’re in the Control Center, drag the Brightness slider to the left to lower the screen brightness.
  • You can also set the display to Auto-Brightness for it to automatically adjust to lighting conditions. To enable this feature, head on to your iPhone’s Settings->Display & Brightness, and then activate Auto-Brightness
  • Another recommendation is to keep Wi-Fi ON at all times. A Wi-Fi connection utilizes less power than a cellular network, thus better opt to use Wi-Fi when you use your phone to access data. To enable Wi-Fi, swipe up to get to the Control Center, tap the Wi-Fi icon, and then connect to a Wi-Fi network. After that, navigate to Settings and select the Wi-Fi to access a Wi-Fi network
  1. Activate Low Power Mode on your iPhone. If you don’t want to exert any more efforts for configuring device settings to save up battery power, then Lower Power Mode is your best option. Using your device in this state will help stretch the battery life enough longer before it dies completely. By default, your iPhone will prompt you that your battery level is going down to 20 percent. The same prompt will show when it goes down at 10 percent. When you reached that percentage level, your device will let you enable Low Power Mode with a single tap, or by going to Settings->Battery, tap the switch to enable Low Power Mode.

When your device is in Low Power Mode, the screen brightness is reduced, device performance is optimized, and system animations are minimized. Syncing or mail fetching activities, background app refresh, and automatic downloads are disabled. In short, you’ve only got the key functions left for use. Yet, once your phone is charged again, Low Power Mode turns off automatically and your device gets back to normal state.

  1. Setting the iPhone to sleep when not in use can also help preserve its battery life. To set the screen to sleep mode, just press and the quickly release the Power key on your device.
