That percentage is updated when you open settings when static it goes back to the usual update cycle. Just because it is updated when you open settings that doesn't mean it is constantly updated. Even battery apps with live tiles have to adhere to the OS update cycle. If the battery percentage in settings was constantly updated wouldn't you think that battery apps would tap into that and be more accurate?
seems kinda silly to me to have to download a battery app to keep track of the percentage. i'm sure the folks at iOS and android are laughing at MS.
A battery percentage would add a certain amount of strain to the battery itself since it has to constantly poll it (if you want continuous, up-to-date levels reported). But I also feel there is no need for a battery percentage on WP in the status bar. When you turn it on, you can see the battery icon on the lockscreen, when unlocked it goes away again. This is the whole point of the operating system, at a glance information.
The only reason you'd want a percentage is if you are the kind of ***** that can't read an analogue clock.
Here's a breakdown for those of you that have difficulty reading a battery icon:
Full = 100% (you don't say?)
3/4 = 75% (that's three quarters btw)
Half = 50%
1/4 = 25% (and this is a quarter)
Good luck!
I don't know what the percentage is but neither do you.
I think at the end of the day when my Android toting budy says "my battery is at 15% what's yours at?" I would rather be able to say "I am not sure exactly but I can tell by the icon its over 50%". Wouldn't you?
Regarding the tone of this thread, part of what's going on appears to be a small culture clash. The long-time WP users were drawn to the OS early and in part by its simplicity, despite missing many familiar apps. Now that the app gap is being filled in, new users are coming to seek something new. The new-comers are asking for features that they had before and the long-timers don't want to lose the simplicity that drew them to WP initially.
The number of requests for live battery meters, notification centers, and quick-toggle buttons for radios is increasing. On the bright side, it means that more users are coming and new features will follow them. On the down side, it means that possibly unwelcome change is coming. I trust that the folks who designed WP had some key principles in mind and won't lose them. They also likely know what a mess WM6 had become and won't be eager to repeat it.
To the OP, several folks have answered this thread's title question: because Microsoft believed in both simplicity and that people use phones as appliances rather than computers. Microsoft wants you to be a "user" of your phone, not the "system administrator" of it. You may not like that philosophy, but complaining here won't change it, although suggesting improvements at windowsphone.uservoice.com might over time. (Or it could be that they just copied the battery indicator from Windows 7.)
That said, there are lots of ways to solve problems. Microsoft could copy its own implementation for status icons near the clock of the regular Windows desktop. (The status bar in WP and the area near the clock of regular Windows are both called the System Tray.) That lets users choose which icons appear all of the time and which ones appear only when they have something significant to say. If MS built some sort of Status Bar Settings page, we could each choose which icons should we treated like the clock (i.e., always visible when the running app lets the tray show) and which should be hidden unless called upon (by tapping the tray) and the battery indicator could have a toggle for "iconic/percentage".
I always thought the reason why MS didn't show a percentage indicator was because it didn't fit in with their metro/modern design vision and the fact that the status bar disappeared was to help create that clean, simple look and feel of Windows Phone.
To be fair, my Nexus 5 running KitKat doesn't show the percentage by default either. I either have to swipe down and check via quick settings or install a 3rd party app just like on Windows Phone.
A good app for WP is called Battery Pro+. I think it's the only one that shows a 100 on the tile.
lust for statistical data humans crave.
sometimes I just want to check my battery percentage... What's so strange about that?
Nothing wrong and for exactly those sometimes, there is a percentage value in settings -> battery saver.
The reason there isn't a battery percentage is because Microsoft want you to concentrate on using the device, not the status of the battery. If it's statistics of your phone that you want then Windows Phone isn't for you.
We don't need a percentage because unlike iOS and Android devices Windows Phones don't really need charging every day.
This made me laugh at 39.2 dB. :wink:Battery %s don't actually mean anything. It satisfies a certain lust for statistical data humans crave, but its ultimately useless and only ever a guess the system makes based on current voltage.Its a made up number.
I'd rather they fix the defect that causes the drain than give me a percentage so that I can keep an eye on the defect. Of course, they could do both.Seach these forums for "Battery drain" and you will see many threads about battery problems on WP8 on different devices. There are unknown problems causing battery drain on WP8, thats why many people need to check the battery %.
