How to Make Your Mobile Phone Battery Last Longer(0)

If your current smartphone won't charge in a day, here are some steps you can take to make it last longer.
Back-to-school sales and the fall may make upgrading to a new phone very tempting. But what if you need to wait a little longer, even if the battery in your old phone drained before lunch and you're only trying to maintain it temporarily?

Thankfully, there are steps you can take to help save power, especially if you're not ready to make a purchase because you're waiting for this year's new hardware offerings, terminating your carrier contract, or sorting out your finances. Here's a guide.

Lithium-ion batteries degrade over time and charging cycles, and it’s not uncommon for a well-used device to experience shorter spans between charges after two or three years of regular use. Even with an older battery, reducing activities that need a lot of energy can provide more time between charges.

The usual suggestions — like turning down the screen’s brightness, avoiding processor-intensive games, keeping the phone cool or temporarily putting the device into Airplane Mode to cut down on network activity — can add minutes. Power-saving advice varies based on your hardware and its system software, so check with your manufacturer or wireless carrier for specific instructions for Android devices (including Google’s Pixel phones and Samsung’s Galaxy models) as well as for Apple’s phones and tablets.

Apple and Google both include a feature that reduces power consumption with one tap: the iOS Low Power Mode or Android’s Battery Saver. (The name varies on Android devices; for example, some Samsung Galaxy phones may call it “Power saving mode.”)

When the feature is enabled, the battery icon turns yellow as the mode reduces screen brightness, pauses some network activity (like online photo backup) and limits app actions like mail-fetching, automatic downloads and other battery burners. Processor speed may also be reduced, and as a result, the phone may run slower.

To find the power-reduction feature in iOS, open the phone’s main Settings icon, select Battery and tap the button to enable the mode. The iPhone’s Low Power Mode may kick in automatically when the battery gets low, but turning it on manually — even after you’ve just charged up — can help squeeze out more use.

In the Battery menu on many Android phones, you can choose between Standard Battery Saver and Extreme Battery Saver (for even more power-rationing) and put the mode on a schedule.

On most phones, the Battery Settings include other features that help you see the overall health of your battery, which may influence your decision on whether to upgrade your device.

The iOS Battery Settings screen includes graphs that show battery power and activity, as well as a list of apps that consume the most power. The Battery Health and Charging screen shows the maximum capacity of the battery; less than 100% means less time to charge. Optimize Battery Charging is usually turned on by default and is designed to extend battery life by reducing the time it takes to fully charge the battery, ultimately increasing the 300 to 500 charge cycles expected for most batteries.
Android's battery settings include a usage screen to show which apps are consuming the most power, as well as a diagnostic tool to help troubleshoot battery issues. When enabled, Adaptive Battery Settings analyzes phone usage and adjusts how much power apps can access.

If you choose to continue using your current phone, you have the option of replacing the battery. Check with your manufacturer for information on authorized repairs, especially if you have an extended warranty or phone insurance.Apple's website has information on iPhone battery service, as does Google's website for Pixel phones and Samsung's website for Galaxy devices.
