Lots of things are different about the iPhone X - not least the 'notch' that bisects the top edge of its screen. This notch is there for a good reason (it contains sensors and cameras used for Face ID and selfies) but it removes much of the space previous taken up by the status bar. What has happened to that information, and how do we get it back?
In this article we explain how to find the battery percentage on the iPhone X. For broader related advice, see How to use the iPhone X. And if you'd like to improve battery performance once you've found out how your device is getting on, see How to get better iPhone battery life.
What the iPhone X status bar shows - and doesn't show
All you get now is the time (in the lefthand slot), and the cellular and Wi-Fi signal strengths and the battery remaining, all crammed together into the righthand slot. There isn't even room for the battery to be displayed as a percentage, only as a graphical icon - which tells you roughly how much power you've got, but not exactly.
(What else has been lost? You don't see the name of your cellular provider, and while the location services icon appears on the left where applicable, and the charging icon now sits on top of the battery graphic, many of the other status icons that used to come and go depending on conditions don't make the cut either.)
How to find the battery percentage
The place to check for this is in the Control Centre: swipe down from the righthand side of the top edge. Above the various controls and toggles in this screen, you'll see that the status bar has been pulled down from the top and now has enough space to expand the battery status into a graphic and a percentage figure.
(Note that is different to the way the Control Centre displays on other iPhones, which blur out the top status bar.)
In fact there are other methods you can use to achieve the same thing. Any time you plug the iPhone X into a charging source, a graphic will pop up showing the current battery percentage. And the ever-undervalued Siri can help here too: just say "What's my battery percentage?" (or even just "What's my battery?") and he/she will tell you.
