[Galaxy S III Q&A, Help & Troubleshooting] Mithrandir007:
I've found a similar problem, and explanations on why it's happening, but it says that it appeared in Gingerbread but has been corrected in Honeycomb and ICS.

It does seem like the exact same problem with the same symptoms though, so I wonder if it really is gone...

Here is the page where I found the info :

http://fivasim.pcriot.com/androsensor.html

And here is a quote from that page :

Update: After many months of testing and debugging I haven't found a way to fix the battery issue for good. Perhaps I shouldn't... It's not really my issue but a general android problem (just google for "gingerbread battery drain"). And it happens with EVERY app that makes use of the sensors that are the root of the problem.

The battery leakage comes from android sensors that are not well supported by the kernel or the android OS. Most usually the accelerometer sensor causes the issue but sometimes the light sensor and the proximity sensor can cause this issue as well. Other sensors seem to have nothing to do with battery drain.

However I have found what's causing it and ways to `patch` over it (unfortunately, no way to permanently fix it).

Trying to invoke a sensor with such a problem, will cause the sensor to stay open even after the app is stoped and disposed of memory.

Another common issue is a conflict. Two apps register the same sensor, then one app unregisters but fails because the sensor is in use by the other app. The sensor stays in use by one of the two apps and this will remain even after both apps are killed.

In most cases there is a way to fix this:

- In the first case, you may just find which sensor is misbehaving (strange readings, very slow response or 'Failed to start' error etc.). Go to AndroSensor's settings and disable that sensor. Then reboot, run AndroSensor once and wait to see if the problem persists. Most usually the light and the proximity sensors are to blame for this issue. Sometimes the issue is caused only if both light and proximity are enabled, but disappears after disabling any of the two.

- If you don't have a misbehaving sensor then there is probably some conflict. Conflicts can be caused (usually in Gingerbread) when having auto-rotate (accelerometer use) or auto-brightness on.

Solution: Go to your device's display settings and disable auto-brightness and auto-rotation. Then reboot, run AndroSensor once and wait to see if the battery drain continues. If the problem persists then there is probably a conflict with some hidden/system service. Most usual is the conflict with SGS and SGS2 secret menu ( by dialling "*#0*#" on the dialer ). I have found no way to bypass this and it can only be solved by disabling the accelerometer and orientation sensors in AndroSensor, then reboot (orientation sensor makes seemless use of the accelerometer).

The only good thing about this, is that in HoneyComb and ICS the issue seems to have disappeared for good!

Am I really the only one with the problem?
[Galaxy S III Q&A, Help & Troubleshooting] chamonix:
Does CPU Spy confirm that problem, showing awake instead of deep sleep?
[Galaxy S III Q&A, Help & Troubleshooting] Mithrandir007:
It does seem to go to deep sleep, but I still see a big difference in battery life between when it happens (around 7-10%/hour), and after I reboot (~ 1%/hour).

Before I start applications using those sensors, the battery life is normal as well, so I don't think it's something else.
[Galaxy S III Q&A, Help & Troubleshooting] Mithrandir007:
I've just made a few screenshots to show what's happening.

Last night, before going to bed, I've rebooted the phone, then started Sygic and AndroSensor, exited the apps, then manually force closed them to make sure.

Then I left the phone charging for the night.

This morning, I remove the phone from the charger, and Badass Battery Monitor starts from that point to calculate the battery drain from everything (so I'm sure neither Sygic nor AndroSensor have been running at all since I unplugged the phone).

Since then, a bit less than 2 hours have passed (I've barely used my phone during that period since I was getting ready then driving to work).

There was a 5% discharge (which is strangely not as much as I had yesterday, but still more than the usual 1%/hour when in standby) and we can clearly see what's eating the battery the most in Badass Battery Monitor.

The "Orientation", "Pressure", "Magnetic Field" and "Accelerometer" sensors have been running the whole time since it was unplugged.

What do you think, is this normal behavior?
[Galaxy S III Q&A, Help & Troubleshooting] Mithrandir007:
I've now installed another custom ROM (Omega 8, with the new samsung firmware update), and the problem seems to remain..

If I'm the only one with the problem, I'm starting to think it might be something hardware (or an app I've installed every time maybe), since I've had the problem with every ROM I've installed...
[Galaxy S III Q&A, Help & Troubleshooting] Mithrandir007:
Switching to another kernel didn't seem to help either.. I'm really starting to wonder if this is something I can fix.

Does no one else have the problem?
[Galaxy S III Q&A, Help & Troubleshooting] Mithrandir007:
I think I've found the reason but now I wonder why no one else seems to have the problem (or maybe I'm the only one who actually cares ;) ).

It looks like it's a battery usage reporting bug in the Samsung firmwares, not an actual drain.

Whenever you run an app which uses sensors (like GPS Status, AndroSensors, Sygic, ...), there is a good chance that when quitting the app, Android will not register the sensors as "stopped", even though they are not running anymore.

This means that the current battery life calculation takes those sensors into account as if they were still running, and the battery % drops faster than it should.

Here's a post from the creator of GPS Status, explaining the problem :

http://xdaforums.com/showpost.php?p=23106668&postcount=491

There is also a small explanation from the author on the Google Play page for GPS Status, I'll quote :

"KNOWN FIRMWARE ISSUES (please do not report them):

- Samsung phones: Because of a firmware bug those phones may report extreme battery consumption for GPS Status (and for other programs using sensors) even if it is not running. This is harmless and no power is consumed! Just ignore it and let's hope that a future firmware upgrade will fix this."

So I'm still wondering if this is something we can fix, or if we have to wait for Samsung to correct that bug?
[Galaxy S III Q&A, Help & Troubleshooting] XDA-Usr:
Yes I care. Thanks very much for posting this. I've noticed exactly the same thing and it's been driving me crazy. Good to know it's just a false alarm. With ICS 4.0.4 coming to the Galaxy S2 soon, maybe it will be fix there.
[Galaxy S III Q&A, Help & Troubleshooting] chamonix:
If this is really the problem that would be an deep in Android or between the hardware and android as it is the 'batteryinfo' service reporting sensors data.
[Galaxy S III Q&A, Help & Troubleshooting] Mithrandir007:
Indeed, I don't think there is an easy fix for this one, unless someone has already worked on that part ((un)registration of sensors from the battery measurement service).

Hopefully it'll be fixed in a future version of the firmware, or in Jelly Bean.

XDA-Usr : maybe it'll be fixed in that version, indeed..

It is just a false alarm, although it still leads to inaccuracy of the battery level.
[Galaxy S III Q&A, Help & Troubleshooting] luzok:
Now 1 year has past since your original post. I'm still experiencing the same problem on my Galaxy Note 2. :silly:

installed leak?
[Motorola Droid RAZR] rigbyrobot:
If it fails to rsd back you probably have been updated to ics, that being the case trying to rsd back to gingerbread will always fail. You will need to rsd to the .211 build. I'd use mats new tool possibly skip to the new 214 leak then use the same bundled tool for rooting. (given you are cdma) I must recommend a full charge for any flashing, a low battery can result in failed flash and also blows your batt stats to hell

You can use "TPSparkyRoot" to root your phone

IF I HELPED YOU HIT THANKS
[Miscellaneous Android Development] ramsuresh4:
Dear Friend,

Can you guide me for proper file link, and proper method (steps).

I searched in Xda, but that is for Asus Epad. Also I got link through gsmarena, but I fear to use those both.

Because, anything will go wrong, then warranty will be void.

Thanks.
[Miscellaneous Android Development] papabubadio:
Hi,

this is the link of the link to the TPSparkyRoot thread. About warranty. It is void from the moment your device was rooted, but mostly they doesn't check if it is. You can still restore it to stock and re-lock it, before you send it to the service.

Have fun!
[Miscellaneous Android Development] ramsuresh4:
Dear Friend,

Thanks for the link. But anyway I know that thread. But I have no driver of my Celkon A 97 to install in my Xp system. Celkon didn't give the pc suite software. But I got driver file for MTK 6575 processor from that thread link. But it is not installing in my Xp system.

So, if you have, please give and guide the steps for rooting.

Thanks.

Have you succeeded rooting A97

Hi suresh,

Have you succeeded rooting the mobile? You got the drivers? And also am facing internal memory full problem. I have moved all thr apps to sd still there is no internal memory.. Is showing like it have a internal memory of 790Mb where as celkon official website claims it have 4Gb internal memory.. Please help.
[Miscellaneous Android Development] ramsuresh4:
Hi Parween & Friends,

I didn't get the driver, so I cant root the phone. I got the mt 6575 driver from the xda links. But I can't install that, that only contains 'inf' file. While connected to my toshiba Xp laptop, system asked to install the driver. But , mt 6575 driver cant install in the Xp system, also I tried in windows 7 also. But not succeeded. I think, after installing the driver only, we can root the phone through Tpsparkyroot method.

Reg. Memory, I didn't test it. I have less applications only. But in usb connection mode, the mobile internal memory 2GB is opening in the system. But after rooting we can install 'a2sd' or 'link2sd' like that, for application moving to external storage.

I request that anybody is having a97 driver?
[Miscellaneous Android Development] droidvijayan:
Rooting a Celkon A97 a Mediatek MTK6575 based android phone

I see lot of people are looking out for rooting the Celkon A97 Phone here in xda and in gsmarena.

For the benefit of all the noobs, I am just listing out how I rooted this Celkon A97. The credit for rooting goes to TPSparky root creator.

The rooting was tested and works fine on a factory 2.3.6 ROM.

Note:

Rooting may void your warranty. Do it at your own risk.

What's needed:

1. USB data cable

2. MediaTek USB VCOM drivers

h*t*t*p://w*w*w.4shared.com/rar/9onOaDl5/Driver_New.html

3. Windows OS (xp/vista/7)

4. TPSparkyroot. You can download it from the mediafire link

h*t*t*p://205.196.123.98/92pj8g8zetpg/9d48ldfadquanj0/TPSparkyRoot.rar

5. Of-course an unrooted Celkon A97

Step 1:

Install ADB driver for Celkon A97 using the Mediatek USB VCOM drivers. Check whether the ADB device appears in Windows device manager.

If this ADB device is not listed in Device manager , you will get "device not found" error while using TPSsparky root.

If the ADB driver doesnot install on your system, you may want to edit the inf file usb2ser_****.inf and update the device id of your phone.

where **** is the version of the windows inside your version of the windows directory and install the driver again.

Step 2:

Rooting using TPSparkyroot.

Extract the TPSparkyroot.rar file. The TPSparkyroot folder contains

adb.exe binary

adb winapi and usbapi dll files.

busybox binary

su binary

SuperUser.apk

RootExplorer.apk ( Chinese version) of an Android root filemanager.

TPSparkyroot.bat shell script AKA batch file

Step 3.

Run the batch file TPSparkyroot.bat as administrator on windows.

The TPSparkyroot.bat has the exploit to gain ROOT access via AndroidDebugBridge. During this time it reboots the phone Three times( Yes three times).

Once it gets the ADB root shell, the next process is using ADB, it copies all the required files to the phone.

The files are

busybox, su binary

Superuser.apk

Rootexplorer.apk

It cleans up all the temporary files it has created. Then it reboots the phone.

Thats it, you will have a rooted Celkon A97 phone upon reboot. You will have two application installed as part of this. 'su' and Chinese version of the rootfilemanager.

My two cents :-)

How is the phone's battery backup?

I have seen this handset at a local mobile store. I was impressed by the build quality and all but, could somebody tell me how the battery would last if the GPRS data was continuously on and we were reading a novel continuously ?? How long would the battery last on extensive use?(Like gaming continuously as well as putting a download in the background and listening to music, all simultaneously)

And how long does the charging take?? Does it heat up while using??

How is the camera's quality in low light conditions??

How much is the internal user storage?

Is there a digital compass in built.(I am not asking about GPS sensor, I need to know if there is a compass built in or not)?

These are the doubts that only can be cleared by someone who has used the phone for certain amount of time. Answers would be much appreciated. :)
[Miscellaneous Android Development] droidvijayan:
Battery life A97

The main battery hoggers in a typical bigger smartphones are

1. Display

2. GPS

3. 3G

It will definitely consume battery if you use all the three at the same time.

Listening to music doesnot consume much battery. A97 has a decent battery life It would last a day with reading novel for couple of hours doing mail for half an hour with GPRS and 10-15calls/day and 10-20messages. 3G consumes more power than GPRS(2G). Of course you cannot download big fat torrent files on a 3G or Wifi and expect the battery to last the whole day.

This phone does a decent job in all the three for the price it is selling at. Even a iphone4-S lasts a same for me. Iphone4 used to last for 2 days.

https://discussions.apple.com/thread/3391947?start=0&tstart=0

And how long does the charging take?? Does it heat up while using??

It charges to 90% in less than a hour if I connect it to a physical charger. On a laptop charge it takes couple of hours.

All smartphones get warm after a continuous extensive usage as it does not have a fan for cooling the CPU and the GPU. It is the same with A97.

I have not observed it getting HOT so far.

How is the camera's quality in low light conditions??

The camera is good in a normal lighting. Any mobile camera is not suitable for low light photography. Low light photography needs adequate lighting which can captured only with a professional DSLR camera with a good flash.

How much is the internal user storage?

It has two types of internal storage. One is 799MB(userdata) and internal 2GB(fat). It also has provision for external MicroSD card which can hold upto 32GB .

Here is the memory dump of Celkon A97.

part no: start_sect number_sects partition_name Size

emmc_p1: 00000020 00000002 "ebr1" 1 KB

emmc_p2: 000cf720 000d6800 "cache" 427 MB

emmc_p3: 001a6720 0018f800 "usrdata" 799 MB

emmc_p4: 00336720 0040b8e0 "fat" 2000 MB ( 2 GB )

emmc_p5: 00009f00 00002800 "sec_ro" 5 MB

emmc_p6: 0000ef20 000c0000 "android" 384 MB

Sects size is 512 bytes. 2 sectors is 1KB.

Size is calculated as ( number_sects / 2) / 1024 . All sect size are in hex. Convert it into decimal.

Is there a digital compass in built.(I am not asking about GPS sensor, I need to know if there is a compass built in or not)?

A97 has a digital compass. You can install tons of compass applications(super compass, Vaastu compass..) from the Google playstrore. You can also enable compass mode in the google maps.
