Attention!!!!!! Everyone with battery life issues please read this!

I think I finally found the solution to lousy battery performance on Android phones in general!
If you are using Spare Parts -or any other battery monitor app- and noticed a near 100% of awake time then,
it's as simple as that:
Go to menu, choose Settings->Applications->Development
and make sure that Stay Awake (second option) is NOT checked.
If it is checked the phone never sleeps while charging, but unfortunately, due to an android bug I guess, won't return to his regular sleep schedule after disconnecting from the charger.
Please try this and let me know! It worked for me!

Do you have Spare Parts installed?
If yes, then you can see what exactly is using your battery.
My solution applies to those who constantly have near 100% awake time.
I hope you find your culprit soon!

Timescape is the culprit.
Force close it and remove it from your home screen and watch your battery life double.

Well i'm having the 100%, so i will defenitely give it a shot. Thank you.

You speak my words absolutely right Timescape is the Main Battery sucker and nothing else. I removed it Days ago including of closing the Process in Taskmanager. my battery Life got up from 7 Hours to 16 Hours. Nothing else had effect for me even changing the Launcher to Helix or whatever.
Timescape / Mediascape is what sucks the X10 down.

No timescape on my homescreen and stay awake is not checked...still batterylife is lousy
Its fine when its not being used but as soon as i start using apps or use the phone in general, the battery drains fast.....

I reset the phone after unplugging it in the morning after a full charge, and my battery lasts a good 18 hours. Thats with Wifi on 75% of the time and 3g always on.

Wow....thats great...how did you manage that?
could you guide me through what settings you use please
cause with wifi on ....i get like half a day!

3 to 4 days with wi-fi off,3g off and gps on......................
don't twit or face though.

After being fed up with barely making it throughout the day, I decided to perform the following experiment:
1) wiped the phone clean (factory reset);
2) did NOT configure my google account with the phone to avoid needless sync with google as well as all those processes running in background no matter data connection available or not;
3) disabled data (as that line I am testing the X10 on has no data plan on it);
4) switched off location services; removed every single widget from the home screens;
5) installed HelixLauncherDONUT and left default widgets + added SE's digital clock;
6) installed startup auditor to prevent stuff like timescape from starting
7) contacts/settings/show status updates changed from all to none
Now after 24 hours and 45 minutes since unplugged phone has 88% battery left!!! There was no usage beside me checking stats every few hours. Phone is set to 3G, so switching to 2G may yield even better results.
Before this test I have done exactly the same test with the only difference of Google account being enabled on the phone (with sync disabled). No matter there was no data connection at all, phone went thru 20% of battery in just 6 hours with same usage pattern - 'no usage, just standby and checking every now and then the status of battery'. Not bad as with normal use of the phone I was been able to make it thru the day without shutting down due to battery empty.
Bottomline, I blame Google services for the excessive battery drainage in this phone. It is 1.6 'Donut' with its outdated google services 'at fault' IMO.
Hopefully with the planned Eclair update (lets hope Froyo too!) this situation will be addressed, at least to a certain degree.
Cheers!

Don't get me wrong. The experiment I've done is a "proof of concept" sort of - I am trying to figure out what is wrong with the battery usage in this phone.
If we look from your point of view, just to have the phone on standby and not using it, not Motorola V3, but a toy phone from the dollar store would suffice.

oh, i know. i just upset with SE, we're here to find some solutions
it's so sad that we buy the phone for the look & the features, too bad that SE did a very bad job. now we have to wait for months to get an update from them, & still don't know it'll fix all the issues???

What I've found out is that most battery drain comes from apps. Install an app that monitors cpu time per app and cpu speed and load. Shortly after I got the phone I was about ready to throw it from a bridge or something because of the horrible battery performance. However, one day I noticed that the cpu was running at ~1GHz most of the time even though it's supposed to throttle down and match speed to need. I found out that one app had ALOT more cpu time that all other apps/services (a widget from DMI, the Danish weather service, in case you care). Once uninstalled, my phone could go through half a day with both 3G and Wifi enable and not even drop below 90% battery capacity - although only mild usage because I was working. Before, the battery went from 100% to like 60% during a night with 6-7hrs of sleep.
Finding out how to improve battery usage has definitely made me like the phone alot more, but I still wish HTC had made the software for it.
Regards - Martin

I get a good full day with my x10. I use Timescape but set the update option to NEVER so it only updates by tapping on timescape tile; i also turn of wi-fi when not in range of my home wi-fi, bt off, gps off (unless needed for maps).
I also trained the battery. Let power off by itself and charging full 4 or 5 times.

as for the google thing id suggest going into settings then data synchronization.. click google and uncheck background data.. it even tells you it will save battery and lower data usage.. whenever you use market though it will ask you to enable it in order to use it.
hope it helps!!

To follow up on my test - 7 days, 18 hours with 3% battery left. Here is a quick video I made: http://www.youtube.com/watch?v=lt2YjrREgxg

for me i use Launcher Donut
and disable data and mms
settings > wireless controls > Mobile network settings > MMS & DATA
try it and tell me how much u will reach in the same daily using average

Removing Timescape & Mediascape totally from the home screens.
and disabling Data Sync>Gmail
battery life is showing huge improvement.

Battery drain while idle - "suspend" process

Hello,
When I got my SGS it only ate 2-3% of the battery during the night. Since then I've tried many different firmwares, currently on the latest JM6, and all of them have had a very annoying problem. It eats 8-10% of the battery during night. I haven't changed anything, wifi is "always on" to avoid it eating battery using 3G. Ofcourse I've tried turning it off, too. The funny thing is that using Spare Parts it seems like it's the "suspend" process using a lot of CPU, which I believe it definately shouldn't. Some times after flashing it seems okay and can sleep properly, but then it goes haywire again - without having installed anything since it worked. Anyone else having "suspend" process using a lot of CPU?
To test, install Spare Parts. Plug in the charger, and remove it again to reset stats (Spare Parts uses some system app to show the CPU usage, and its default view is "since last unplugged", very practical). Go to bed. Sleep. Wake up. Start Spare Parts. Select "Battery History". Click "Other usage", select "CPU usage". Wait for half a minute or so (it needs to load data, if you click anything now you won't get CPU time used). Find the "suspend" process. Check how much CPU it has used.
I might add, that this doesn't seem to have anything to do with wake locks, it's something strange in the system itself.

try next time with all unecessary items off
like WiFi, GPS, BT anything that you don't use when you go to sleep

Thanks, but I've noticed something strange - still checking, but it seems as if I haven't got my SD card inserted, it looks okay...

I use JM5, Wifi Always on, 3G Always on, Auto sync off when unnecessary.
I was working at the polling booths on Election day here in AU, that's from 7:30AM till 11:30PM, I didn't really need to use my phone for anything, but when I got out 16 hours later I noticed that I had only lost about 3-4% battery.
It's pretty good. D:
For the record:
Bluetooth - This only needs to be turned off if there are devices that auto-pair with the phone, such as a bluetooth headset, in which case you probably want it on anyway?
GPS - This does not need to be turned off as it only uses battery when a service is actively requesting a gps fix. For example if you have Maps open it will drain more battery, but it won't on standby unless you are using Location tracking software or otherwise location aware software.
WiFi - Truth to be told, WiFi when connected uses less power than a 3G connection on standby. WiFi does have the potential to use a lot more power than 3G because of the higher speed potential over a local wireless network. In most cases it's pretty safe to have WiFi always on, however it should be noted that when WiFi is NOT connected it will constantly scan for access points to connect to, this process uses power ON TOP of 3G, so it would be wasteful to leave this on unnecessarily unless you were using it for Google Location services via WiFi access points.
3G Data - The only reason this 'uses power' is because it's a always-on connection, you can partially remedy this by giving WiFi always-on priority saving both mobile data quota and some power. 2G uses a lot less power than 3G simply because it uses the GSM chip in the phone, not it's own higher power chip. So switch to 2G if u don't need high speed data, but want always on Push notifications and such. (EDGE is fairly fast, but I only get GPRS and 3G on my carrier. )
Brightness - This phone has a super bright screen, use something in the lower settings, auto brightness at day if you want.

I've got bluetooth off all the time, it's currently running a very new install of JM6, and I haven't installed anything that runs when I don't want it to run. 3G isn't used, as wifi is always on (advanced wifi settings).
It's around 7 hours since I pulled the plug, after having restarted phone after removing SD card, and the suspend process isn't even on the list anymore... I find this quite interesting - it might just be a coincidence, but right now it looks like there is some kind of problem with suspend process when SD card is in... Do you have an "external" SD card in your phone?

ive just flashed JM1 and hate how much power its using... no idea what the problem is, but ive just come off the official JM1 from Kies, and had a big problem so had to flash the first thing i could find. can this really be down to firmware?
i mean im really noticing a difference on standby, before id loose like 3-4% in a whole day of not using it, now it drops 10% in like a few hours...

i do use 16GB class 6 external SD from Transcent

MoWa22,
I had this happen to me last night and (am stock DXJG04) so very interesting. Trying to remember what my battery drain was last night but I think it was around 10-15% and previously I would get 1% if I turned everything off except being able to receive calls.
I always thought these issues were related to wake locks or that the phone just cannot sleep. Something to try is to reboot the phone and check the battery power before going to sleep and see the battery drain over the night. If minimal battery drain, then maybe it is a rogue app which you may have opened/used during the day. If same 8-10% drain, then am guessing some service or inbuilt process is causing issues.
Half the battle is trying to track the CPU hog or rogue app.

Dang. Lost almost 10% again tonight - but actually the "suspend" process almost didn't use any CPU, SD card still not in phone. Using the built-in battery usage thing, it has cell standby on top, phone idle right below. This is really starting to bother me...

Last night while I turned off APN, Wifi, GPS, etc, I left my phone on as 3G only. I've heard the switch between 3G to 2G causes extra battery drain so I had left the phone on as 3G only. I know 2G is lot less of a battery strain but wonder if it affects cell phone standby. Going to leave my phone on 2G tonight.

I have 3G and sync on. I have weather and feed widgets updated every hour. Plus some other widgets and Google Latitude which I know is using cpu time. My drain is about 1 to 1.2% drain per hour of standby. Firmware DJG4.
I think you dont need to bother too much if battery drains 1-2% per hour on standby (this gives you at least 2-4 days if you use the phone very little). Any more than this means you may have some rouge apps/widgets.
The more critical is the usage time (i.e. with screen on). This is usually like 15-20% drop per hour of use.

Been testing a bit again - this night I had a total of approx. 1% battery used in 9 hours. Still without SD card. I inserted the SD card one hour ago, and I've lost 5-6% already - and suspend process is on top of the list again... Definately something weird going on when SD card is inserted! Please, can anyone test with/without SD card and check for differences?

I spotted this thread and read with interest as last night I noticed my power dropped "unreasonably". I've not started any troubleshooting yet but I am curious about the SD card thing.
Have you tried having the SD card in, but unmounted? Does it still suck powere when unmounted?
Obviously unmounting it is a simpler and quicker process than removing the cover and then physically removing the card.
Mark.

Upgraded to the new Froyo today, seems to be without suspend problems even with SD card. Gotta check how much battery it'll eat during the night.

How did you manage that? Everything off? auto-sync off? Wifi? 3g? 2g?

I'm on jm5 with Samset 1.9f and for all the time ive had this phone it has only used 2% battery overnight. Exceptional cases were when i used Fancy Widget, it ate up all my battery overnight leaving me with nothing for the next day. Have stopped using it ever since.
Nowadays, my battery drains heavily when screen is on(when im using the phone). Drains roughly about 1% for every 2 mins im using it, but standby time is still great at 2% overnight...

The new Froyo beta JPC. Same settings as always - WiFi always on (which by the way seems to be default setting on JPC). Everything else standard (it won't switch to 3G while using WiFi).

Gets hot and uses battery while idle

Recently I have noticed on several occasions that my phone have gotten hot and started eating away the battery. One time I had around 30% battery and the phone was laying in my pocket. I felt the heat through the pockets and took it up to see what's up. It then had 0% battery and turned itself off.
When looking at battery use in settings, it's hard to pick out one specific application that might do this. If anything it would have to be "Android system", right now it's tied with the screen on 40%, but I charged the phone an hour ago and I haven't used the screen much.
Edit: I should add that the same thing just happened, from 99% to 89% then it stopped. That's why the information above about battery usage is relevant.
Do you think it might be hardware-related, like a partial short circuit or something, or is it most likely a software thing?

Bump. 10 signs.

Had mine for a few days, have not experienced anything like what you describe
I have though felt the screen get hot when turned on full brightness and reading a e-book on it (white - black text)

Well this is while it's laying in my pocket, with the screen off, so it's not the screen. (it's the battery that gets hot)

Take it back.
[Funny story that probably isn't relevant. I had a dodgy micro sd card that made my phone drain battery super fast and as a result my phone got incredibly hot. Took it out and it's back to normal.]

Sounds software related to me, your android system should definitely not be 40% of your battery. It sounds like some rogue app/process is utilizing your cpu and thus your battery very heavily. If you select the "Android system" in the battery usage list, does it not give you a further breakdown of what is included in that that is using your battery? Also, what does it say for the cpu time for the android system?

May be firmware bug
I've had this happen to me a few times when I was running the original firmware. In some early firmware there was a bug related to switching between wifi and 3G, which would get it stuck so that you couldn't toggle wifi on or off. The times this happened to me, it was also stuck in the wifi bug (although I had the wifi bug and it didn't drain the battery).
I now run the newer firmware (JG4) and both problems have stopped.

I've had this problem with my asian i9000 since the beginning. The app called Top showed me that it is ksoftirq/d that is running and System Panel showed me that the cpu was running at 100% at 1ghz.
At first the only solution seemed to be restarting the phone. However some information shared on this forum led me to try restarting wifi which also works. For that thread search for "ksoftirq/d."

I have had the "stuck wifi" bug, but I'm not sure if it was happening the last time this happened. I'll check it out the next time.
There's no official firmware update on Kies for Norway yet, so I think I'll wait for one.

Had exactly the same problem and tracked the culprit - it was Fancy widget in my case. Removed it, installed Beautiful widget and all is well since
Sent from my GT-I9000 using XDA App

That might actually be it. If I'm not mistaken Fancy Widget had 30% battery consumption when I checked. I deleted it just to see if it would make a difference. So far so good.

Some details:
Fancy Widget will hit the 100% cpu on auto-refresh if there's no data connection available (either wifi or cellular). It seems there are 2 bugs with Fancy Widget; it ignores "auto-refresh off" option and it tries to connect to server even when offline.
A dirty work around would be to set refresh time to let's say 12 hours and make sure to manually refresh at least once every

That makes me even more convinced that Fancy Widget is the culprit. I usually have cellular network disabled (APNDroid On/Off Widget) to save battery and my wifi connection keeps loosing connection, probably due to some software bug in XXJF3 stock firmware.

Insane Battery Drain...Please help

This is my first android phone and I'm wondering if I am doing anything wrong. Yesterday I charged my phone and it was at 83%. I unplugged the phone and went to sleep, when I woke up this morning the battery was completely drained.
This happens a lot. Even if I am not doing anything it still drains like crazy. I just text, make some phone calls and it barely makes it through the day. I don't play any games, no gps, no Bluetooth or anything. With my plan, I don't have a data connection so I can't connect to 3g/4g so that shouldn't drain anything.
What could I be doing wrong? When I'm done using the phone I tap the power button on top, the screen goes black - to sleep I presume and I put it away. I had an iphone before this and I did exactly the same thing and the battery lasted for 3-4 days on one charge.
Whenever I see what's using up the battery, the display tops the list. The display is using up 75-80% of the battery. If the phone is asleep for most of the time why is the display using up that much battery? Am I not putting the phone to sleep correctly?

If you cant connect to 3g/4g, you should turn it off in settings. Otherwise, Your phone will constantly look for a signal, draining your battery.

Battery life is all relative. Every single person will experience different battery life. The apps you have installed, the amount of time you spend on it and the time you spend on/in each app, distance from cell towers, distance from Wi-Fi sources, settings you have for every app and things like sync and what not.

The first thing to check is if your phone is being affected by the init or suspend bugs. The good news is the former has an easy fix, and the latter can be temporarily fixed by a reboot.
First, download & install Watchdog Lite from the market. Then open its preferences and check "include phone processes," "monitor phone processes," and "display all phone processes." Then just use your phone as normal. It may take a while before you get an alert from Watchdog (and maybe you never will and it ends up you have a different problem). But if you do, note the process that is the culprit.
If it is the init process, go to settings>applications>development> check "usb debugging."
If it is the suspend process, reboot the phone. It should keep it from happening again for a while.
I know the second answer isn't really an answer, but so far it's all we've got for that problem. There is more information on the 2 problems in these threads:
Init:

Suspend:

Good luck...I had both of the problems and my phone didn't last to dinner time. Now I get better battery life than the iphone 3GS I had before this...about a day and a half of moderate use.
EDIT: also you'll probably want to go to settings>wireless & networks>uncheck "mobile network" since you don't have a data plan. No reason to have that on since you don't have a data plan.

Does Watchdog use a lot of system resources when running in this manner? Will it cause the battery to drain noticeably faster?

Completely unnoticeable, IMO.

I installed watchdog lite and I have had couple of alerts. I got suspended couple of times and I also got Android system once.
Android system - 50.1%
Foreground
Suspend - 54.4%
Linux Process
I turned off the data usage from the settings and it did help save battery. The display is not using so much battery life anymore. It went from using 70% to 35%.
Edit: Battsatt reported that the battery was at 93%. When I saw the two alerts above I rebooted the phone and Battsatt now starts reporting the phone is fully charged.

Make sure the GPS is turned Off, too...

All these answers and the easy ones were not mentioned..
Make sure you shut your AUTO SYNC off...
Make sure you lower your brightneess....
Make sure you turn off GPS(was stated above me)
Turn off your wifi if you are not using it.. make sure you are not transmitting your hot spot stuff...

You just summed it up right there. You are experiencing the 'suspend' issue, period. There is no app you can install to fix it. There is no app you can uninstall to fix it. There is no setting you can adjust to fix it. There is no fix for the 'suspend' issue, literally.
I started the following thread in an attempt to consolidate posts and hopefully work toward flushing out what the real issue is...
http://forum.xda-developers.com/showthread.php?t=872839
This is a real, legitimate issue with Android 2.2.x Froyo. As I linked in my post, this is Issue # 11126 on Google Code...
http://code.google.com/p/android/issues/detail?id=11126
If there was an app or setting that fixed the 'suspend' issue, we wouldn't even be discussing this right now. There are fixes/workarounds for a lot of things, but right now, the 'suspend' process issue truly is a mystery. No one, not a single person has yet to post, "this is the cause of the issue," let alone a fix for it.
I wish you had a fix man, I really do. My fiancee experiences this and there's only one way she's found to sort of workaround it, sort of - she reboots her phone every morning. This seems to keep it at bay, at least more so than when she doesn't reboot each morning, once she takes it off the charger. She still gets it though and she's just used to looking for Watchdog and checking her processes now.
This thread could go on and on forever but it comes down to this:
- The MT4G does not have insane battery drain and will give you about 12 hours of life, under normal>medium usage. If your battery is draining insanely quickly AND if you're seeing the suspend process jacked up so high, then there.is.no.fix.yet.
There might be a ton of other replies after this about uninstall this, install that, change this, don't use widgets, use widgets, etc. Those attempts will be futile.

Unexplainable battery drain

For a month or more I'm facing totally unexplainable battery drain.
As seen on the screens below, the phone is awake, but it is not detected anywhere - not by android nor by GSam. In any case the battery draws faster.
I have one observation tho - this happens after I make phone calls. Not every time, but once per 2,3 days.
Any ideas?

You have this problem
http://forum.xda-developers.com/note-4/general/explanation-horrible-note-4-battery-t3004274

I'm pretty sure that I don't have this issue. Yes, the percentage in GSam maybe high, but I don't believe this reflects what is happening.
First of all - I don't have bad battery life. Usually my over night drain is less than 1%/1h.
Second - the issue appears sporadically.
Third - in the provided thread I don't see the issue appearing in stock battery monitor, while mine appear.
At last - my battery drains faster only while the issue is present and before I restart. After that it is back to normal ...

@Spo0f
Just some suggestions maybe you're using 3g I always have that turned off and switch it on when I use it my guess is that some apps are causing your drain after a call maybe like you said if you're not fimiliar with greenify I suggest you use it to stop all those apps and system apps also uninstall all those bloatware you don't need or at least freeze them if you don't mind lower the resolution to 1080p with nomone app use power save or disable dvfs and use an app to lower and raise the CPU to save juice when not needed....

Thanks for the suggestions, but as I said - this problem appear sporadically - home when using WiFi as well as outside when using 3G.
All of the rest is done - I'm no newby

Oh sorry mate well I don't use much 3g so I can't help you there but if you're having drainage when you're using WiFi in general then maybe you should reconsider investigating the post above with the link I don't have so much drainage on connectivity with 3g or WiFi....viewing the pics you uploaded it seems suspicious.... Maybe an app? I don't know...

Use wakelock detector

My overnight drain was also very low, but that was because the faulty device on the network was asleep at night too (my desktop).
If you're not rooted, use the PC version of Wakelock Detector at the end of your day and post screenshots of your highest drainers for the various categories. In my case, the device was being woken up by something on the network and it showed.
Bear in mind that actively downloading something in the time period will also raise wifi power used but more stats will help.
The fact that you're still experiencing a lot of drain even when outside suggests it might be a rogue app

One phone call today and after it the phone stayed awake.
Because I had issue with the PC WLD the screen shots are from 11 minutes after one of the disconnects. The device was awake all of them.

I also checked out my battery behaviour this night and was very disappointed. Although my phone was in flight mode and every peripherals and services shut down, today morning my phone was crying for energy. So I made a quick investigation in my power diagram and found out, that "Android OS" requested a wakelock during the whole power-on time. So I installed "CPU Spy" to check in which states the phone was really over the whole charging period. I couldn't believe my eyes. Although the kernel should do it's job good, cause most of the CPU times are in lower freqeuncy states, the deep sleep mode was never activated.
Therefore I installed an app called "Wakelock Detector" to check out which apps could cause that. I found out, that S Health had a big amount of wakelocks and also active-time, so the first thing was to disable S Health. After some minutes I checked back, but nevertheless still no deep sleep time in "CPU Spy".
So I searched around and found another one arguing about the wakelocks and that they could be the products of some programming issues concerning WiFi. The should be gone, after turning off WiFi and rebooting yout phone. And it seems that he was right. I waited some time and hooray, "CPU Spy" listed the phone state "Deep Sleep" the first time as an active state and also with the major active-time. So at least that was some step ahead. (I have to remark, that S Health was already unfrozen at this time, so S Health should not be responsible in any way.)
The next step was to reactivate WiFi, leave it on and set the phone on standby. After some time I checked back again the phone showed even more deep sleep time. So that was an improvement. I reactivated everything and waited some time... Deep Sleep all over the time. Can't figure out for now, if it was S Health, WiFi, or anything else that caused the wakelock for sure. At least the reboot helped. I'll check that out on a long-term test, maybe I get some further conclusions.
