You'll need to figure out whether convenience or privacy (and potentially power savings) is more important to you. It also means that can't track you wherever you are, all the time. Note that turning off persistent location means apps can't alert you when you're near a friend or there's a special offer nearby.
#HAVE SELFIE LIGHT FOR IPHONE HOW TO TELL WHEN CHARGED HOW TO#
How to reduce background activity on iPhone and iPad So if you only browse Twitter a little, but you listen to audio a lot while your iPhone is in your pocket, then you'll have a more activity taking place when the display is off. The activity chart uses a darker blue color to indicate activity that took place while your screen was on, and a light blue to indicate activity that took place while your screen was off. This chart shows you how much time your device was in use, broken down either by hour or by day. So if you, for instance, ran your phone's battery all the way down, charged it, then used it some more on a particular day, you'd see usage over 100%. When looking at the last 10 days, though, you'll get a day-by-day look at the percentage of the battery that you used. When viewing your usage over the last 24 hours, you'll see how your device's battery behaved, the period of time over which it drained to a certain level, as well as when it started charging (denoted by a green lightning bolt icon at the bottom of the chart). The first is Battery Usage, which is pretty straightforward, though the chart actually changes based on the period of time for which you're getting information. Just like the app-specific breakdowns, these charts can display information for the past 24 hours of the last 10 days. IOS 12 will come with breakdowns of your overall battery usage in the form of two charts. (That's not surprising-Facebook has historically been so callous about power consumption it borders on user hostility.) How to understand the power usage readout in iOS 12
It's using almost twice as much time in background as it is on screen, which is ridiculous. Instagram is doing even better, using only a tiny fraction of the amount of time in the background as it does on screen.įacebook, though, is the worst. So, for every minute I'm using it, it's taking less than a minute to complete actions and otherwise finish things up. Looking at my screen, Tweetbot is really high but I use it a lot, and the background isn't out of proportion to screen time. If you've barely opened an app and it's still showing a very high level of battery use, that's where your attention should go. It's when the numbers don't match what you're actually doing that there's likely a problem. Likewise, if you're downloading a ton of podcasts or streaming a lot of Beats 1, Overcast, or Music, it might show really high "background" usage. For example, if you're reading Twitter or watching movies on an airplane, Tweetbot or Videos might show really high "on screen" usage.
Now, just because an app is using a lot of power on screen or in the background doesn't in and of itself mean there's a problem.
That's why Apple shows you "on screen"-the screen lit up-and "background"-the radios and processors working when the screen isn't lit up. The screen lighting up, radios transmitting, and chips processing are the biggest single causes of power drain on your iPhone or iPad.
