Hi everyone,

I appreciate that there are threads on this already but this is different.

I have created a petition because Samsung support have not acknowledged that there is an issue. There recommendation was to "Factory reset".

It has been identified by members of the forum that the mA in battery stats used to calculate Cell Standby % has been set ridiculously high.

Please see explanation here.

Rooted users can fix this by flashing more realistic values here


I would like everyone who has the issue to sign the petition, so we can send it to Samsung and prove how much we like this fixed.

Link is here:

http://www.ipetitions.com/petition/samsung-galaxy-s3-cell-standby-issue/


Moderators, please do not merge / delete. Could this sticky please?

I've stuck this thread for you guys .

Let us know when this is no longer an issue and we'll un-stick.

Good luck and I hope you get some results.

Cheers!

I didn't sign as I would like to see proof this is a real issue and that Samsung knows about it and they are doing nothing.

Also FWIW, every single smartphone I have owned, I have seen threads where someone says the battery does not last long, someone else saying it does not last a full day then others say they have no problem.

If its a real problem soon there will be 9-10 million S3's in use so lets see what happens. Lets see thousands of posts about it not a handful.

Its not about how long the battery lasts. Its about how much battery the battery statistics show is being used by cell standby. Want proof? Settings > Battery

jerofld

It's not the best example of it, but overnight I had the phone in airplane mode (where usage plateaus) and cell standby is still the highest.

Realistically, display or device idle should be the highest if kept in airplane mode.

I hope this issue will be solved.
Petition signed.

I am pretty certain the people reporting this issue are in areas where they have crummy service.

The galaxy s3 defaults to LTE at least for at&t right? If you live in an area with no LTE and/or HSPA+, wouldn't that cause some battery strain?

SUroot

My device isn't lte

So this is what a recompiled framework-res.apk looks like with the miscalculation of 34mA recalculated as 3mA (SGS 2 was 2mA)



This is based on some information I received from an XDA member.

To answer your first objection, see quote below:

In answer to your second objection, why don't you contact Samsung yourself, then you will know they know about it, and when they don't reply, then you will know they are doing nothing.

Pep

I've signed as the cell standby is usually double my screen usage

Mine to.

So what does a full day and 7 hours use (31 hours+) with still 17% left tell me?

It tells you that if you read the thread, you'd have the answer.

This was never about battery life.

rushmore

What is the problem? A calculation issue and or an actual battery drain issue?

I am thrown off based on posters talking about coverage areas.

SUroot

Calculation. The Radio power usage is set too high in battery stats so it isnt reporting accurately.

zigson

Is there a different calculation used on different networks then, because I'm getting varying cell drain in different countries?

Geordie Ahmed

What is the screen time for that?

SUroot

Varying usage based on incorrect values

How would doing a factory reset fix this problem?

It wouldn't. The values are incorrectly in the framework.

This is so annoyng. I was finally happy to have a phone that puts my battery worries behind, but it turns up that i have to charge it twice a day.

I really hope that they will fix this soon.

SUroot

To let you know, I have re-reported this issue to Samsung, including the 150+ signatures received so far

MisterEz

Sorry for what might be a stupid question, but if Samsung fix this does it mean that our batteries will last longer...?

Pothers

I'm quite happy with the battery life I'm getting so far but think it would be better if they fixed this issue.

I've only had my GS3 since last Saturday and I'm getting 2 days. But it drops about 15% over night. Alright I leave wifi and full sync on but I did that with my Desire HD and that only lost 3-5% at night.

Again I'm not complaining, as long as I can get a full day I'm happy, I just think it could be better

SUroot

No. battery life is already good (or should be with the correct settings).

All it means is Cell Standby will be calculated so it will appear a lower %. The overall % wont change though. Whatever % is reduced from cell standby, will be added to the other components, such as screen, android os...

ScootD

I seem to always get high cell standby usage on my Droid X. I've preordered the S3 so we'll see how it compares once it arrives. If this is due to incorrect values in a framework would the issue exist regardless of what carrier's network the phone is on? I guess I just don't fully understand the nature and origin of the proposed incorrect values and framework that were given as a possible cause for this.

kkalll

My colegue also has S3 and he gets 2 days of battery.

Im getting like 9 hours max and this is so disappointing. And this is with almost no use, just checking some things online and making few calls

If Samsung come up with update for this, will it solve the problem?
Cause if not I'll have to try to get a replacement.

FYI i am using galaxy ace.

same issue cell stand by higher than display.

Was thinking that the phone was using more battery to optimize the radio signal.
could be.

But the inaccurate stats could be an issue.

Flumme

@Kkall> This issue is about how the battery stats are wrong, in regards to how Cell Standby is reported in the battery usage stats.

When (If?) Samsung rectifies this, the only difference you will notice is that the reported Cell standby drops to the correct, actual, number.

Your very bad battery time is another issue all together. Possible causes are bad reception, dud battery, bad charger, settings for updates, screen brightness, rouge app, syncing...

Have you let the phone die completely a couple of times? This might help break in the battery...

kkalll

Hm I thought that the cell standby issue is causing my battery to drop so fast. I treated the phone from day one like my last htc and I cant figure out what can be the problem. Ill try letting the battery to die some more times and if that is not helping then what?

SUroot

Here's an update for you all:

Thanks. The article has got it wrong. Felt the need to leave a comment

Doit2it

So what the article got wrong was that the 34mA error doesn't really affect battery life, just the reporting of it in the battery stats, right. Are they correct in their statement that this will not be an issue with the US LTE variants?

SUroot

That's correct.

In regards to US, although drivers will be different, I highly doubt they would have changed power profiles.

kkalll

OK, if cell standby issue isnt affecting the battery life, why it is such a great problem?

Wouldnt it be a better idea to sign a petition for the bad battery life on some devices (such as mine)?

Dont get me wrong, no bad feelings its just that my battery seems to drain fast and Im just trying to get to the bottom of this.

SUroot

Initially it appeared to be a battery life issue, when this thread started. Then we realised battery life was actually really good. I still want accurate battery stats as this is the basis for identifying battery issues in the future.


If you are having battery issues, then something else is using your battery. You will need to investigate this as I for one am very happy. Its better than my 1Ghz single core HTC desire.

Apps like "betterBatteryStats" may be a good starting point.

Although you say you have bad battery, why not post your stats and pics in one of the existing battery threads?

Images are only useful if you include:

Main battery stats page
Battery stats graph (detailed by pressing it)
Screen on page.

kkalll

Thank you, sure, I'll do a screenshot this evening when my battery go low

Hustletron

I have a screenshot of my usage here. Not sure if its what you guys are talking about.....mines a GSM version.



Not sure if it worked since I'm in my phone and linking to my dropbox. If not heres the URL http://db.tt/pBPbRvCO

Just something i noticed.

Have been flashing roms lately, Found that the display reading is more and cell stanby is insignificant.(pretty low).

So Definitely something that can be rectified software wise.

SUroot

Yes they've all started implementing the "fix" linked in post 1 of this thread.

warwing

Well in that case the problem is fixed as most of us simply root n mod.
n dont depend on stock.
