At the very least it would be helpful to know why this change was made. The commit referenced above seems to reference an internal issue number not something from this issue tracker.

I'd like to see access to batterystats added back to Android.

I vote for this too.

And at least, such big changes that affect many applications should be announced in the release notes with a reasonable explanation of why it's been done.
There are also other such changes in the 4.4_r1 when compared to previous releases (4.3) and that isn't very good approach towards 3rd party developers.

As a user I want to be able to see these stats too.  I there is not a really good reason, this function should be restored.

As a user I want to be able to see these stats too.

As a user, I would also like to see this.

Apps to get better stats saved my batterie multiple times. 

This need to be fixed

Starting from KitKat  users  are not able to easily detect  "No-Sleep" bugs which is very well known Battery Drain cause. 

This change must be reverted

Ich möchte als Anwender den Batteryverbrauch ermitteln können.Ich möchte diese Statistiken sehen.

I'm curious about what the motivation for this change was. Are we missing some security issue? 

thanks so much but i think battery not save 
 

I vote for this!

I would like battery stats back as well.

Battery stats is beneficial for many users, it should be reverted to its previous state.

I would like them back too

I vote for this.

i vote for this too. without apps like this,  devs would not know if their apps have bugs that drain battery.  without that knowlege,  issues will not be identified and fixed.  users would get frustrated and would eventually swich to the other side. you wouldn't want that,  right?? 

I vote for this

I vote
 for this.

I also vote for restoring that permission, as there are lots of users who were benefiting from third party apps that detect abusive uses of battery and wakelock. 

Battery status permission is one of the distinguish feature from iOS.. i would like get this permission forever.. strictly vote this issue...

The one above me somewhere about iOS, and the one about third party apps,
that is the main reason why I want this permission moved back to the user
category.

I vote for this!

"According to a study made by P. Vekris: “55% of 328 applications using wakelocks do not follow our policies for no-sleep bugs” [2012]. Some major applications have been released with No-Sleep bugs."

How Android developers and users have to deal with this issue  in KitKat??

Please fix. Also please don't remove the gallery app. I don't want the dang Google Plus thing.

Be careful Google. 4.4 is looking more and more like you're going to piss a lot of people off.

I vote for this too, it is useful to see what is draining the battery in the case of aosp roms. 

Another unacceptable and unneeded change within Android. Please revert as suggested by the op.

I don't like the direction where android is going. Closed source changes, never a good thing.

I vote this too. How can I use some of the battery status apps that I like?

I vote for this too

Have my vote!

I'd like to see Wakelock Detector at the android 4.4 very much!

I absolutely vote for this!!!

Folks, please STAR the issue in the upper left hand corner of the page instead of constantly adding a vote comment. Vote comments serve not but to annoy the crap out of everyone who has starred it.

i vote for this !!

Not cool Goog.give it back.

I vote for Ruud. I need this app

I vote for this

Please allow battery stat permissions. Very useful for monitoring!

 Posting a comment that "you vote for this" does +nothing+.  Make sure you highlight the star near the top off this page.  That gets counted as a vote for this issue.

I agree with all of the above.  That someone could make this change with little or no consideration as to the negative effects of such a change is frustrating and a bit scary.  Is there no oversight of changes like this?  You don't change APIs without major justification.

In trying to deal with putting the backup control mechanism in the wrong place, they "fixed" the problem, but caused a much bigger problem.

They should have removed the backup controls from the battery info/status api and created a separate api for that function.  They took a shortcut and we're now seeing the downside of taking shortcuts.

Reverse this change.

Really need this back. Used an app for my Nexus 7 and found a couple of games were the culprit. Having issues again with something and now I have no way to find out. Frustrating as my partner was going to get a Nexus 7 but not until we can identify why my battery is terrible.

As a user, I would also like to see this.

Please reintroduce as required for wake lock analysis .

Please undo

I vote for this!!

Please undo this change asap! It makes no sense to me!

for the last time people,  click the star at the top left of this page,  typing "I vote for this" does nothing and you are annoying the people like me waiting for a useful response from Google or a workaround from the more capable dev community. 

Please undo this

I voted that I want my battery stats back. I use GSAM app everyday to know what's going on with my apps. 
I find we are entering Apple territory, that is, Big brother knows best and can control whatever he wants.

I vote for this.

Bad decision. Please restore this functionality so that apps like Wakelock Detector can work again. It helped me understand why my phone's battery occasionally drained after wireless charging.

Vote!
Undo this change or explain.

PLEASE DO NOT COMMENT if you have nothing constructive to say (technical information, information on why Google changed this, etc). DO NOT just say "I vote!!"

Bad time for that move, for me the KitKat update came in just after the trouble with Google Play Services keeping lots of devices awake and sucking their batteries empty. Starred.

I *ed the issue but would like to explain WHY this tool is useful from a user perspective.

After updating to 4.4 on my Nexus 4 I've noticed that my phone will go from a full charge to almost dead or fully dead /overnight/ (depending on how much I sleep in).  The class of applications that use this feature are the only tool I have for determining where the fault for this change in behavior lies and thus how to begin fixing the issue.

For those of you who have issues with overnight drain, put your phone on airplane mode and consider force stopping offending apps. I did that last night: when I went to sleep it was 88%, when I woke up it was 88%. Same story for most of the other times I did that. Regardless, I would definitely like to see this issue fixed; this is an important permission that shouldn't have been revoked in the first place. That said, I'm sure Google is on it.

Google, please make KitKat more user-friendly.

Something is keeping my phone awake and killing my battery. I used to be able to diagnose such issues, but not any more. Thanks Google!

Voted for this.  I seriously need to use applications which cause no-sleep problems.

I vote for this too!

Please undo this

This is an important issue that needs to be resolved.

One can suppose this permission was removed to prevent battery monitoring apps to blame other apps (including Google apps) for (supposedly) bad behaviour.

Starred issue, would definitely like this reverted please.

Bitte wieder Rückgängig machen

I vote for this... This service is critical for general troubleshooting 

I vote to revert this code so that BBS+ works again. 

What's wrong, Google? Afraid that msm_hsic_wakelock issue (which has never been solved and eats my phone's battery in a day) was getting too much attention?

I vote for this

STOP WRITING "I VOTE FOR THIS"! Simply click on the star!

As to the issue, I think that what happened is really a shame.

First of all, I sort of agree with the user that said that this could be a way to hide battery drain problems caused by Google services under the carpet. These problems must be solved, and if Google thinks that an "out of sight, out of mind" approach is an acceptable solution, well, this is a real problem.

Also, giving users the possibility to understand what causes a battery drain in their phones is important, that's why the choice of restricting the battery stat service is definitely an unfortunate choice. One of the reasons why Android gained traction over iOS is its flexibility. Now Google is going in the wrong direction.

Another big problem is the way Google is handling Android OS updates. I see two major problems:
1) there is no early access to newer versions of Android OS (betas) prior to official release
2) too often there are changes that break existing applications, and too often those changes are not documented and not disclosed to developers in advance.

Consider what Microsoft does with Windows... of course it's impossible to guarantee backwards compatibility to every applications for every new version of Windows. But new versions are released to developers many months before their actual release date, so developers (and common users) can test their applications with the new version.

So Google should really change the way they handle Android OS updates, otherwise its developers will get annoyed and switch to WP development as soon as it reaches a decent market share (which will happen).

This is the second time I've seen a comment like this:

"2) too often there are changes that break existing applications, and too often those changes are not documented and not disclosed to developers in advance."

I am very much in favor of restoring this functionality but everyone here needs to keep in mind that this was a private undocumented API. Apple and Microsoft aren't going to notify developers about changes to internal APIs anymore than Google has in this case and nor should they.

I want it back !!!

I would like this back please.

I vote for this!

I agree - upgrade policy is disgraceful.. features should be added not removed or broken.

sorry, but this move (and such) will drive end users away after developers start giving up..

"I'm curious about what the motivation for this change was. Are we missing some security issue?"

I'm also curious. Could the batterystats/batteryinfo make the device vulnerable to side channel attacks?

Voted.

Why would functionality like this be removed intentionally?

Maybe they have reason to do this, but seems we really need to hear a proper explanation.

I vote for this as well and would be very interested to know why it was changed in the first place!

Please undo this change. 

Google, please undo this change. As an user I found very helpful the detailed level of info provided by apps like BetterBatteryStats in order to diagnose which apps or services are draining the battery and in which cases. 

How can an os update ever be allowed to break apps that adheres to api's? Please ensure compatibility and proper regression testing before you roll out updates Google. This change is breaking one of my favorite apps. If battery stats truly breaks security why not offer an alternate interface/service to devs so that existing apps continue to work with a bit of porting work? 

Agree with the above.  The standard usage readout does not show all apps and doesn't provide enough drill down, especially when it comes to wakelocks, to be useful. The manner inwhich this has been introduced has also been ddisconcertingly opaque. 

Voto para esta modificação ser revertida !

I vote for you undo this change !

I need this feature.

Fixx

Open Source... ?
I need this feature restored as soon as possible.
Kitkat is killing my Nexus battery. Probably due to the "improved" gnow intagration.
Fix!

What happened to open-source?? Come on google remove the restriction pls.

I would like them back too

Please add them

Add them.

Please fix so I can monitor my battery again without root 

Dont you guys understand why Google dont want us to see stats? Because almost all the time the problem of drain has to do with 
google services. Google just doesn't want people to deactivate their services, instead of fixing the bugs.

People, dont you realise? Android will become closer and closer. It already started a few versions ago. It will become almost 
as closed as Apple. Mark my words. Keep this message. From 3/4 years you will see. This is not a hunch, it's just 
facts...

I hope Tizen soars up, and be a viable alternative and aim to be to what Android used to be.
