[Q] Read battery log after restart

I have an issue I'd like to debug, but I need some information to help myself:
I charge my SGS (JM1) in the evening, when it's 100% full I disconnect the charger and go to bed (23:30), phone switches to airplane mode at 24:00. When I get up 8h after, my phone is off and has absolutely no battery left.
This happens every now and then, IMHO there's no app causing this (haven't installed anything lately). I can't reproduce the issue.
How would I best debug this and try to find out what's causing the battery drain?
Can I still read the battery log after a restart?

Don't see Amy bad apps.
You can.use sgs toolbox to see the battery usage is.
Some make the phone almost never go in powersave mode.

Thank you so far.
I looked at the battery usage stats and saw that bluetooth was enabled for more than 7 hours (although it was disconnected). That IMHO shouldn't have completely drained the battery though...

I am seeing the same problem recently; the battery drains out really quickly in no time even when there are no major apps running. Even the battery usage menu shows nothing major. During this time I have noticed that the phone gets really hot and the battery indicator app shows that the battery temperature as b/w 40-50 C (its around 25-35 C when there is no issue). During this time I can't even make calls or send/receive SMS!!! Seems that it just cannot get a network signal.
There were no such issues for the last couple of months. I can't imagine an app directly or indirectly causing this.

If an app keep the phone awake all.the time and use wifi/Bluetooth/gps it will drain the phone fast.
The only solution is to find out where the flaw is.
Personal i would backup the phone and do a complete wipe/ reset of the phone so it will be clean and like new. Then i would test to se if it drain the battery.
If it does then it is broken and need a.repair. Else i would start to intake the apps i need, but looking close what they do.

Have you installed any lagfixes recently? When I had voodoo lagfix on jg4 I would get at best 8 hours of stand by time. As soon as I flashed jpm I get 1% drain per hour
Sent from my GT-I9000 using XDA App

I have not installed any lagfixes, my phone is on stock JG4 firmware. The battery life is otherwise very good, only at times (very random) the battery starts draining from 100% to 0% in a matter of few hours.I use System panel to check if there is any app that is causing this, but it does not indicate anything like that.
The only thing that I can think of is that the phone for some reason looses network (I can't make a call and send/receive sms during this time) and keeps trying to reconnect without success and hence drains out the battery. Once I reboot the phone everything becomes fine and the battery usage becomes normal. Is there any way to find out that the phone is trying to connect to the mobile network and this is causing the battery to drain out?

Neither do I, never used any lagfix so far, I'm on stock JM1.

That's possible but I don't know how to log this...
Gnarf, it just happend again. Before going to work it was all normal, now it's frozen.
I connected it to my computer, but WinXP recognized it as an unknown device.
ADB doesn't work, else I had pulled the logfiles.

maybe u should consider upgrading to JM7 or JM9. and before installing apps do a full reset and cache wipe.

I'm waiting for CM 6.1 to sort it all out, given that "FroYo by Samsung" still isn't what I expected it to be - at least judging from the betas.

[Q] Since updating to JPO, my battery drains at around 8-10% per hour.

This isn't a little rise in battery draining. This is an absolutely ridiculous spike in battery usage. I left my phone overnight, and it dropped from 90% to 37% within the 8 hours I left it sleep.
Is there anything I can do? This is stock JPO updated via Kies. Will changing ROM or Kernal fix this? Because quite frankly, I am sick of this. I can't take my phone out for the day without it dying on me.
As far as I can tell, it's not the sensor bug some people are experiencing, as I'm not seeing any suspicious usage in the battery history.
Any help would be very much appreciated as I'm seriously debating getting rid of the phone. I just can't keep it with this appalling battery life.
Thanks.

Turn off auto rotation and data connection (3G). That should improve your battery life siginificantly. You don't need to check your emails in your dream do you?

Thanks for the reply.
I have auto-rotation off as default. It is really plausible that data connectivity is consuming this much power? I never had this much battery drainage in Eclair, even with auto-rotation on, data connectivity on and with the screen at maximum brightness.
I've downloaded APNdroid and will see if turning of data connectivity will help, though I very much doubt it. I'll update here in the case that it does though.

Do you have a exchange account configured?
It's known to drain your battery at that rate when not set to "Push" (generic Wake Lock problem in Froyo)
Also, if you don't mind spending a few bucks, install System Panel app and let it monitor CPU, that way you'll find out which apps are the top battery users (while asleep, battery drain is fairly equal to cpu usage, so the top cpu-usings apps will be the drainers). I have 75% battery left after 10 hours of light usage with Bluetooth. Auto Rotation and 3G enabled.

The only email I use is Gmail, synched to my phone. I've noticed that a fair-few people are having battery issues with a number of suspected causes. The exchange email setting being one and the sensor issue being another.
Would flashing to a custom ROM fix this issue? Or would it still persist? I really wouldn't mind flashing to a custom ROM if it fixes this absolutely pathetic battery life I have at the moment.

if you have any task killers installed try uninstalling.
I had advanced task killer installed and was experienced battery drain..not as much as you but if it helps it al counts

I don't use any form of task manager besides the stock one, which I use on rare occasions.
I'm really debating just trying to flash with any old ROM to see if that fixes the issue.

Are I using the ext4 lagfix? If so there's your problem there. Also to fix gallery bug you just need to root phone and use root exeplorer to copy fixed gallery.apk into /system/Apps. Putting new modded Tom won't fix it as thy mostly use old default gallery which has sensor bug. Look in search to find gallery3d.apk file

I'm not using any lagfix at all. It's stock JPO updated via Kies. The only modding I've done to it is rooted it.
How would I go about checking whether or not the Gallery is the cause of the battery issues?

[Q] Darkys 9.5 Wlan causes Battery Drain

Hey guys,
the day before yesterday i flashed Darky's 9.5 on my phone.
This is the first Darkys version for me. The flashing was fine and very easy but then i got big problem regarding the Wlan battery use.
First i tell you how i flashed Darkys, perhaps i did a failure here.
1) First i flashed Darkys Reserrection Version on my phone
2) After that i configured the Darkys App from the market and flashed the reserrection.zip with CWM
3) At the end i flashed Darky's 9.5 with CWM
Now the points regarding my problem.
Yesterday night i switch off my phone with at least 85% battery. I switched off GPS,Bluetooth and i deactivated the data transfer mode for UMTS. But it was my intention to test the battery drain with active WLAN, because with the original T-Mobile Firmware the phone uses circa 25% battery a night.
But when i woke up i was really shocked. My phone turned off and the battery was complete empty. In this night the battery drained 85%. How is this possible? There were no apps running excepting the Advanced Task Killer.
Did i something wrong? (When i flashed the battery was fully charged)!!
//edit
Here are my settings:
PDA: I9000XWJS8
Phone: I9000XXJVE
CSC: I9000XXJS1
Kernel: DarkCore 1.0

I wouldn't think this was a common issue. Have you tried just re-flashing the ROM again via CWM? Maybe try the same thing again?

Thx for your answer.
Yeah i even think that it's not a common issue.
I will watch the battery this night. If the bug occurs again, i will flash the Rom with CWM again. Have i to disable the lagfix or can i do it on the fly without changing something in the current system ? If yes, where?

my battery is the best its been in a long while since using this rom so i wouldnt dismiss it just yet. what modem are u using?

I use the modem Darky's App Configurator has recommend (JQ1 but i have read that JVE is flashed (se my settings above)). But i think I will try flashing again. This night the battery drops from 100% to 47% with the same settings I mentioned above. Then i watched the battery usage, but they were strange.
Wifi and "Wifi using" uses 100% cause they were running the whole time. But the category "execution" used 75%, so the phone did not drop into sleep mode for about 75% of the whole night? How is this possible? I checked all my 3rd party apps I installed on my own and they don't have a setting to manage this.
Does one app of Darky's Configurator do this?

Well Darky can answer question best .
Me i blame the rom change the rom .
jje

Now i flashed Darkys 9.5 with wipe again.I will watch the battery drain and I will notify you about the result.
//edit
Now I go asleep and I will report tomorrow if the flash was successfull. But I got one question left:
By accident I saw in the wireless setting window that my phone scans every 5 seconds for new devices, even if its connected to my own router. (If the phone goes to standby the WLAN does not scan cause of my settings). But why das it scan every 5 or 6 seconds, even if it's connected to my own device?? Is it possible to increment the scan time?

Good morning guys,
here is my update:
I think the reflash worked. Last night my phone uses 10% battery with wifi and data transfer on, gps and bluetooth off. I think this is a good value.
By using the flightmode the next times I will save some more
Now there is the question left regarding the number of wifi scanns. (see the post above). Is it modifiable ?

Did you recalibrate your battery after upgrading to Darky's 9.5?
It is recommended that u recalibrate your battery when you flash a new ROM.

You shoukd recalibrate your battery, i.e. drain it, turn off your phone and fully charge it, completely drain it (use it heavily). Then charge it again and voila, recalibrated!
Also, I find that after flashing a new ROM the battery drains really quick the first 2 times I charge it, before actually working as it should. So it's not that strange that your phones battery was dead in the morning. But I think this also has to do with recalibrating the battery.
Darkys v9.5 has a battery life of 3-4 days for me (not heavy usage) so it should be better after recalibrating your battery!

horrible battery life >.< help please

so yeah,,, i got a nexus one from a friend of mine (whos done alot of flashing and installing custom roms on this phone so i dont really know whats running) but it drains about 10-15% battery every hour or so.
ne suggestions on how i can figure out if its a bad rom or a bad battery??
thanks

Easiest way to know if it's the ROM is to flash a new one. I suggest cyanogen mod it is some what simple but works well and battery is just fine. There is plenty of documentation on the forum to show you how to flash but if you still can't get it just ask and I can walk you through it. You may also want to check settings -> about phone -> battery use to see what uses up the most of your battery.

you could try calibrating the battery

so ive ran some tests, basically fully charge one time without simcard and another time with, to see if the radio drains more battery. and both times its about the same.
i did order a few batteries off ebay, but probably will be like two weeks or so before they come in.
mmmm the md5 stuff kinda confuses me haha, dont know how that stuff works

You don't always need to check md5 you can if you want but most people don't just make a nandroid backup and that way if the file is corrupted you just flash it back and your good. But if you do want to check them just download ManD5 and check to see if the one on the file matches the one on the website.

Under >Settings >About Phone >Battery >Battery Use
What are the top 5 applications and what %?
Wifi should be set to never sleep. under >Settings >Wireless >Advanced >Wifi Sleep Policy
Find out which ROM and radio are being used. Cyanogenmod7.x or OxygenROM would be good for battery life.

You should also try charging the phone to 100% and then wiping battery stats.

Does your phone get warm when charging?
Having swapped ROMs back and forth, wiping everything, I get the same bad battery life (-10%/30 minutes). Wife's N1 runs fine, ours ran the same stock OTA versions until this. I needed to see if it was something related to the OS and tried some alternatives.
Replaced battery - no difference (wiped stats, etc)
Turned off data (wifi and non).
I can't tell when the radio was updated on mine - if it was related to an update that would correlate to the problem, but I have the latest radio that has been out a while.
Logcat looks just fine. It's not data related, nothing seems to be going on when charging...
My hands are cold, using the N1 as a hand warmer right now (it's plugged in)...

There's a bug with CM's kernels causing a LOT of battery drain when you set the wifi sleep policy to anything but "never sleep", check that and change it in case it's not. I know it sounds counter-intituive, but it really works.
I set mine to "never sleep" and easily last a full day on a charge. I also calibrated my battery using the battery calibration app, and using a plain black background helps somewhat if your N1 is AMOLED

[Q] Phone runs hot, High Drain - All usual fixes tested.

Device: Samsung Galaxy S GT i9000
Symptoms:
When Charging Device is hot to the Touch in the upper half of the screen and on the rear between the camera and the heat vent.
Battery drains at around 15-25% per hour when IDLE. 15% when in deep sleep in airplane mode with ALL APPS KILLED. 25% when I leave ALL network connections open and allow sync.
Phone was new less than 2 months ago. Still under warranty and I will send it back if no ideas come from this but wanted to see if anyone had a solution as I have noticed HUNDREDS of similar posts all vaguely scattered through different threads on different sites around the web and this seems like the definitive place to come to see if anyone can put their finger on it.
When did this occur?:
A short while after (days) of flashing CM9 nightly from the beginning of June (05/06 I think but can't recall exactly).
Tests performed:
Purchased new battery and fully charged - no change.
Flashed stock GB ROMs where the issue had not occured - no change.
Cleared battery stats several times - no change.
Tried different modems/radios including Nexus S radios- no result
Current ROM: CM 7.2
Kernel: Glitch 13.1
Other ROMs/Kernels where the same results were achieved...
CM9 (latest nightlies)
Stock JVU, JVS, JW4 and JW5
Semaphore Kernel, Devils Kernel
I use Voodoo Sound/Colour kernels apart from the testing I did with stock ROMs
Will leave it on over night after clearing stats so you can see for yourselves.
Any questions ask away.

I should add:
Used OS Monitor and one of the more detailed CPU monitors to look at what was going on.
Did not appear at any time to be using what I would consider high CPU utilisation, typically trending between 0 and 30ish. No background apps running, all radios turned off.
The only anomaly that stuck out at me is that system_server was using ~105% of RAM which I would have thought was rather difficult. Made me wonder if there was something loading/unloading itself from RAM.
As I am a heavy music user I have tested the Mediaserver issue where corrupt files are continually scanned by mediaserver process. Removed all media files from both my external and internal storage then formatted both while on a stock ROM (JVU and JW4). There was no change.
EDIT: I should add - The thing that makes this so strange to me is that the battery decreases at a rapid rate when Battery stats regarding usage DO NOT CHANGE. The percentages for the apps that WERE using the battery - i.e. winamp/mediaserver/android system do not change.
The reason I have posted this is that i have seen literally HUNDREDS of people posting this very same issue but never in the same place and never getting an answer.
Also - Thankyou to the kind mod/admin who approved my account so I can edit stuff. It was getting a bit annoying for the first week there.

Re
Hi,
To be honest I never heard/read of the problem you are describing. Most users report high battery drain on a certain ROM/kernel/modem but you say you have tried quite a lot.
If the phone is new, the only thing that comes to mind is that the USB charging socket is faulty. It may not charge properly or even have some bad connectors that are damaging the battery.
In any case, Samsung support is the way to go here.
Hope this helps

OMG, im having the same exact problem... the phone is super hot on the back where the sim card is inserted. I did everything as you, still no change, my battery lasts like 7 hours on deep sleep. Guess our phone is broken. super crap.

Anyone knows how to fix this? Is there anyway that my phone has some files from previous custom roms even though used odin to flash samsung original ones?

Had the same problem when my device was only 6 months old, the battery was becoming faulty, got a new battery and problem solved.

I bought a new battery and i still have the same problem... which battery did u get?

An official samsung battery from Amazon, re flash you device with another rom and wipe battery stats.

Did all that, the problem still continues... mega battery drain and the phone is at 44C degrees... is there any tool i can use to diagnose the problem?

Hi snaleman,
You could try BetterBatteryStats, to help diagnose your issue further, there is a paid version on the market (Google Play Store). There is also a thread on this forum, from the dev....hint
I tried winamp for android, ages ago, but had similar issues. (This player might well be your issue.) So I now use "PowerAmp". Neutron MP is cool too.
Also, do you use lippol94's kernel cleaning script. I use this every kernel/ROM change.
Search here for this:
ultimate_kernel_cleaning_script
Hope this info helps your baby.

Hey
U can try to flash a stock rom from sammmobile.com..
Use it for a few days and check...may help u..

Backup your apps with titanium backup or something else.
Make a backup from CWM recovery
Wipe data/cache/dalvik
Restore user apps and not system app
If your problem is not fixed you can restore your CWM backup

Nothing you guys posted worked... battery lasts 11 hours on sleep...

Another problem that im facing is that when im on a phone call, theres is alot of breaks in the other persons voice and sometimes the voice call goes out and i lose all my network signal.

If you are using the Voodoo sound app that may be the cause. I've noticed on my phone that deep sleep no longer works when the voodoo app is installed, most likely the app is holding a partial wake lock and not releasing it.
See if it happens with the app uninstalled or frozen.

You've just made me think of something else that it may be.
Do you have 4 or 5 bars of signal strength?
I've found when in certain areas (very close to "deadspots" in network reception), that if I use another frequency, [eg. 900 & 2100 (for my network), yours may be different] I can get a better signal, also much better battery life, as the phone is not struggling to reach the network.
If you use your dialer to enter this code
*#*#197328640#*#*
Then
[1] DEBUG SCREEN
THEN
[8] PHONE CONTROL
then
[7] NETWORK CONTROL
then
[2] BAND SELECTION
you will then have a selection of frequencies available. The asterisk * will tell you what one(s) is/are active.
"Google" your network service providers frequency bands. I found mine were on a "Wiki" page.
