About That Maximum Capacity Percentage<\/h3>\n
Whenever we hear complaints about iPhone batteries, the first place we look is in the Battery Health screen to make sure the battery is healthy. Apple says that iPhone batteries are designed to retain up to 80% of its original capacity after 500 charges. The higher the Maximum Capacity number, the better. Usually, anything above 90% is OK, although we start to hear of problems when the Maximum Capacity is in the upper 80s, and numbers below 85% are fairly likely to cause problems. The only solution to a battery with a low Maximum Capacity is replacement; contact us for our advice on the best way to do that.<\/p>\n
Identifying Battery Hogs<\/h3>\n
Assuming the battery\u2019s Maximum Capacity is high enough, the next place to look for what might be causing excessive battery drain is in the Battery Usage By App section of the Battery screen; look below the graphs, and tap Show Activity for more details.<\/p>\n

Scrutinize the entries at the top because they\u2019ve used the lion\u2019s share of your power. In the screenshot above, No Cell Coverage (which causes the iPhone to waste power searching for cell towers) was the worst offender. You can\u2019t do anything about that (unless it\u2019s indicative of putting the iPhone somewhere it can\u2019t receive a signal or a failing cellular radio).<\/p>\n
For the apps underneath, make sure they\u2019re not working too much in the background unnecessarily. \u201cUnnecessarily\u201d is key\u2014if you see Photos at the top of your list and Show Activity reveals a lot of background activity, it\u2019s probably related to it uploading or downloading a lot of images from iCloud Photos. But if you can\u2019t imagine why a particular app is sucking down precious power, it\u2019s time to force quit the app or power cycle the iPhone. And if the problem continues, it might be time to reset the iPhone and restore from backup, just to clean things up.<\/p>\n
Analyzing Battery Usage<\/h3>\n
For figuring out which app might be causing unusual battery drain, it\u2019s usually best to keep the time frame in the Last 24 Hours, but if you\u2019re trying to track down a pattern of app behavior, it can be useful to switch to the Last 10 Days using the toggle above the graphs.<\/p>\n
Most people don\u2019t realize these graphs aren\u2019t just pretty pictures. You can tap in the graphs to select 1-hour chunks of time in the Last 24 Hours graphs, or 1-day chunks in the Last 10 Days graphs. When you do that, the Battery Usage By App list changes to focus on just the apps used in the selected time period. That\u2019s helpful for tracking down exactly what was happening when the battery drain took place.<\/p>\n

We\u2019d like to say that you can use these tools to figure out nearly anything that\u2019s causing your battery to drop precipitously, but there are issues that the Battery screen doesn\u2019t expose. For instance, after you upgrade to a new version of iOS or switch to a new iPhone, background tasks will likely work hard for a while indexing all the content on the device. Most issues like that should go away quickly, though.<\/p>\n
Regardless, it\u2019s worth looking in the Battery screen whenever you feel that your battery life isn\u2019t what it should be. Whether it\u2019s a rogue app or the revelation that you need a new battery, it will provide some guidance. And if you\u2019re still in the dark, let us know, and we\u2019ll see what we can do to help.<\/p>\n
