– Device Than What Longer Charge 2 for the Manufacturer Recommends Don’t the
Constantly checking email, texting people, listening to music, watching videos, using apps, playing games. All those activities eat up a single charge, causing our phone batteries to run out of gas, often sooner than expected. For that reason, many people myself included probably charge their phones overnight. Leaving it plugged in longer is pointless. So what happens if you act as I assume most do, and leave your phone plugged in overnight?
First, the good news. Cadex manufactures battery charging equipment. Edo Campos, spokesperson for battery-maker Anker , echoes that sentiment. So your phone is constantly being bounced between a full charge and a bit below a full charge. The more you use it—for checking Facebook, streaming Netflix, texting with friends, whatever—the faster your battery drains.
The more your phone sits in your pocket or bag, the longer its battery will last. Of course, many of the things that you bought a smartphone to do require the screen.
But a quick and easy change that can help extend its battery life without much fuss or annoyance is to shorten the delay until your phone automatically turns its screen off. This tweak reduces the amount of time the screen is on each day. For example, if you unlock your phone 25 times per day, and your screen-lock delay is three minutes, changing the screen-lock setting to one minute can cut the time your screen is on by up to 50 minutes.
When you are actively using the phone, you can extend the battery life by reducing screen brightness: A Moto X Pure Edition Android phone used 30 percent less 21 percent of a full charge versus 30 percent.
In bright environments, the screen gets brighter, in dim environments, it gets dimmer. In a moderately well-lit office, our iPhone 6s test phone used only 16 percent of a full battery over an hour of the Geekbench stress test with auto-brightness on with initial brightness set at 50 percent. In other words, enabling auto-brightness will save most people a good amount of battery life compared with setting it to a bright level all the time, though not as much as if you kept the brightness down all the time; the advantage of auto-brightness is that the screen will remain easily readable in all environments.
If you spend much of your smartphone-screen time on the Web, one of the easiest ways to make your battery last longer may surprise you: Install an ad blocker. But ads, just like any other form of online content, use resources: Your phone must download the ad images and video and then display them often running browser scripts too , and these tasks use energy. We ran an automated Wi-Fi Web-browsing session in Safari on an iPhone 6s, cycling through a set list of websites for two hours with no ad blockers; then we ran the same test with the 1Blocker ad blocker installed.
We ran a similar test on a Moto X Pure using the Ghostery Privacy Browser and got results that were even more dramatic: A feature called push automatically delivers new email, new or revised calendar events, and updates to your contacts list such as from a Gmail or iCloud account to your smartphone whenever such changes occur on a central server.
Although push is convenient, the feature can use a goodly amount of power, as it requires your phone to always be listening for new communications from your account provider. But the more accounts you have on your phone, and the more messages and events each of those accounts receives, the more energy your phone will use, as it has to communicate with those account servers continually. For example, to compare the effect of push versus fetch on the same email load, we tested an iPhone 6s Plus configured with three email accounts, receiving a total of 20 to 30 messages per hour.
Over 24 hours with push enabled, Mail was active in the background for about 18 minutes. When we switched to a minute fetch schedule, the same phone, handling roughly the same amount of email, was active in the background for only 4 minutes over 24 hours.
Alternatively, you can enable push for only those email accounts on which you really do need to see messages immediately, using fetch or manual for the others. More and more people are using streaming services such as Apple Music, Pandora, and Spotify to get their tunes.
This active connection consumes a significant amount of power in comparison with playing that same music if it were stored on your phone. Some services, including the paid versions of Apple Music and Spotify, let you download individual playlists to your phone. In Apple Music, for example, you just tap the cloud icon at the top of a playlist.
To get the maximum battery savings, you should perform these downloads while your phone is on Wi-Fi and plugged into power. While battery technology continues to improve, smartphone batteries remain sensitive to temperature—they work much better when you use them in moderate temperatures. On some models of phones or older operating system versions, it also disables GPS. Though the mode was originally designed to prevent phones from theoretically interfering with airline communications, it also reduces battery usage—all that wireless circuitry requires power.
Indeed, in our testing on Android and iPhone smartphones, enabling airplane mode resulted in the battery level dropping by just a few percent over four hours during normal use or as normal as use can be when the device is in airplane mode, as we note below. Contrast that to nearly 10 percent over four hours during the same type of use with airplane mode disabled. For example, on an iPhone, enabling low-power mode disables email fetch, the Hey Siri feature, background application usage, automatic downloads of app updates and other data, Wi-Fi scanning, and some visual effects.
Both platforms can automatically switch to low-power mode when the battery level dips below a certain threshold to squeeze an extra hour or so out of your phone when its battery gets low , or you can make the switch manually at any time.
In our tests, both iPhones and Android smartphones used significantly less battery power with battery-saver mode enabled—as much as 54 percent, depending on the phone we used. While both airplane mode and low-power mode conserve battery life, they do so at a heavy price. With airplane mode you lose the ability to communicate with another device, be it a wireless keyboard or another phone, as well as the ability to access Internet services.
If you forget to disable this mode, you might miss calls and text messages or be unreachable for loved ones. This limitation makes a smartphone less, well, smart. We recommend using these modes only when you must, rather than as regular battery-saving methods.
The easy procedures above will produce good results for many people. But if you use your phone a lot over the course of the day, if you frequently use location-related apps and services, or if you regularly find yourself in areas with bad cellular or Wi-Fi coverage, you can expend a bit more effort to improve battery life. Both phone platforms provide a simple way for you to see which apps are using a lot of battery power. Using this list, you can quickly see which apps are the biggest battery-use offenders.
Examples might include an email app that spends lots of time checking for new messages even when your phone is asleep, an RSS reader that updates articles in the background, or a fitness app that constantly monitors your location. The Facebook app for iPhone was a notorious battery killer, using lots of energy in the background, though a recent update claims to have fixed the issue; the Android version recently came under criticism for the same problem.
Introduced with iOS 9, Low Power Mode is an easy way to extend the battery life of your iPhone when it starts to get low. Low Power Mode reduces display brightness, optimizes device performance and minimizes system animations. Apps including Mail will not download content in the background, and features like AirDrop, iCloud sync and Continuity will be disabled.
You can still use key functions like making and receiving phone calls, email and messages, accessing the Internet and more. And when your phone charges up again, Low Power Mode automatically switches off. This indicates that the battery was used by the app while it was in the background — that is, while you were using another app. Location and Background Location. This indicates that the app is using location services. This indicates that the Home screen or Lock screen was displayed on your device.
For example, the display was awakened by pressing the Home button or by a notification. No Cell Coverage and Low Signal.
Always make sure your iPod is using the latest version of Apple software. Put your iPod in its dock or plug it into your computer, and iTunes will notify you of available updates. This will prevent iPod from accidentally waking up and using unnecessary power.
Use the backlight only when necessary. Always make sure your MacBook is using the latest version of macOS. The Energy Saver preference pane includes several settings that determine power levels for your MacBook. When using battery power, it dims the screen and uses other components sparingly. If you change this setting to maximize performance, your battery will drain more quickly. Dim the screen to the lowest comfortable level to achieve maximum battery life.
For instance, when watching a video on an airplane, you may not need full brightness if the cabin lights are off. Wi-Fi consumes power, even if you are not using it to connect to a network. You can turn it off in the Wi-Fi status menu in the menu bar or in Network preferences. Disconnect peripherals and quit applications not in use.
