I got a heavy battery drain after flashing to the official Kies 2.2 here in Norway, on JM2 I had over two days usable time, now down to a normal day.
I've reset it several times, tried running it without any apps at all, still heavy battery drain. After checking the battery statistics/history I can see under "Partial awake time", Android System, 2 hours after 14 hours "uptime". And under "Sensor use", Gallery eats up 9 hours, 11 mins. Now what the hell is that about T_T
At least waiting for the new official fw in november.. At least the GPS got better for my part, so it's not all bad
After updating to the official 2.2 that came here in Norway, I started experiencing heavy battery drain compared to before.
After some digging I noticed under *#*#4636#*#* and Battery History and Sensor Usage, Gallery is on top! And it's using the phone's sensors almost 100% of the time it's been on. So, now; the phone has been unplugged for 12 hours, 14 minutes, and Gallery has used the sensors for 12 hours, 4 minutes. Doesn't make sense.
I suspected wifi to be the culprit to begin with, as it throned at the top in the normal battery drainage-graph (about phone, battery usage), but even if I turned off wifi, 3g and autosync over the night, the battery percentage fell just as quickly.
Now, I've tried resetting the phone several times, as I thought it was an installed app that caused the drainage, but that wasn't the case. So, what else can I do when a reset doesn't do it?
Using a GT-i9000 with JPM/JP6 non-rooted.

Well, for what it's worth I too experienced exceptionally high battery usage when I updated to JP6 via KIES hack (same version as yours). Downgraded to the latest stock ROM for my region (Eclair JG4) and the issue is gone.
Now I think I will wait for the official 2.2 update for my region (although, having had a peek at what Froyo has to offer I think I can pretty safely even skip it without missing much).
I too notice a lot of power drain and general lack of ram. What I found was that froyo has a crapload of startup services/processes compared to eclair. I disabled most of them that could be removed and replaced most of the rest like k9 for email and handscent for messeging. System seems less laggy due to more free ram and more power as CPU isn't bogged down by extra unwanted processes like samsungs remote wipe and stupid sns

I'm also suffering from battery drainage with Froyo (JP6). I was quite satisfied with battery use on Eclair. Froyo has reduced battery life almost by 50 percent. I have same programs and I'm using exactly the same settings than with Eclair. I haven't noticed anything odd from the battery history statistics though. Only strange thing is that phone reports that screen in consuming over 90 percent of the battery all the time. Well, that's just not true.

it's a sensor issue, looking at the spare parts batt usage stats. but no idea what sensor/app is the culprit. very annoying
An App I use daily for all manor including checking battery usage is 'SystemPanel'. It's been a God-send and sorted out many a problem.
There's a Free & paid version but the App is that good I immediately went for the paid App.
In 6 hours battery has gone from full charge to 85% in standby mode.
Is this normal? Charge goes awfuly quick when using the phone.
3G on, all syncs off.
Running on Froyo reg hack. Same problem on Eclair!
Phone is 85% charge from full charge on idle over 6 hours.
3G is on, 2 bars showing. WiFi on, not connected.
Display 50%, WiFi 30%, Cell 14%, Phone 6%
Froyo, Eclair same usage except Wifi connected better with Eclair on home network...
2 meters from wifi transmitter and signal fluctuates.
Also, anyone's stock browser lags with yogurt? Was good on eclair
Is it because of fash? Seems to lag on all sites now.
Just to add to this... I had similar battery life in Froyo... HOWEVER, yesterday I used the Gallery and my battery drained from full in under 10 hours with no use (overnight standby with data off).
I check my battery stats when i switched my phone back on and they're okay for the 'since last unplugged'... however... for 'all time' gallery is also my highest user!
So, looks like gallery is only a problem if you use it... if not, it's fine.
crabby
I also have like a 2hr sensor usage on my gallery...
About the light sensor atleast on the JPM/JP6 theres like 2 steps of brightness full and low.. is this normal ?

+1 for that app! Paid one with possibility to see history over time..

Sensor usage for me was also 100% in spare parts, even if the phone was off. I had to turn off auto-rotate, and it quickly became a lot less. Although I have to say it haven't solved my problem! My battery consumption with full brightness over wifi is 10%/30 min. That's just ridiculous. I'm still on the problem, and will update anything I find out. We could actually make a "BIG BATTERY DRAINAGE" thread, where everybody posts detailed logs about the drain.

I have the payed version, How do I set it to monitor battery usage and show w/c app is using the battery so much ?
i'm on jp6 and my gallery is eating up my sensor usage too ):
looks like I've got to restart everytime I use the gallery.

activate monitoring under "menu / settings tab"
then you can see look under menu/monitor and select history tab..
on top tab where it says plot you can select top apps.
/H
just a question. you guys that are experiencing the sensor issues, are you on jp6? could it be a jp6 issue?
Exchange email accounts are a huge drain to in Scandinavian Froyo
If you set up Exchange email accounts, setting the Email retrieval update interval to anything else than 'Never' results in a continious 10% CPU load, draining the battery two times faster than in Eclair 2.1
Set it to 'Never', or have Tasker kill the Email app x seconds after Display Off
Determined by using System Panel app.
I have notice a large battery drain overnight with the OFFICIAL samsung froyo JPO. I suspect it may be the gallery/sensor issue.
1 can anyone affirm this.
2 can we replace the gallery or fix it
tanks
JPA was better for me. With JPO I noticed that the media scanner would eat up the CPU all the time. It seems to get stuck on certain files more easily.
I have enormous battery drain on my phone (Gingerbread) and it shows that phone is constantly "awake" and drained 25% of my battery in 2 hours. Majority is taken by "phone idle" and graph shows that it was almost 100% awake all that time even though I never used a phone.
Phone idle as a top consumer is normal. If you have the screen on a lot, it should be close to the Display consumption.
As far as a fix, I saw this on GB before upgrading the radio to .30P (I am on ATT).
Saw a dramatic improvement, which makes me conclude that the new radio is optimized to GB, whereas the .15P was only good enough for FroYo.
check for social network apps and widgets that update themselves constantly... i had the same issue and fixed it by freezing the social network stuff and setting my others not to check at OCD levels....
If you've got time on your hands and "System Panel" app from Market, this is going to be really worth it:

System panel is by far the best tool for this. Paid version with monitoring tracks all apps hitting your cpu. Must have.

I can second that. My phone was draining battery like crazy after Gingerbread. I flashed the .30P radio last night, and now it looks like it is back to normal. I'm on AT&T as well.

I'm trying the system panel solution. But it seems to be telling me nothing (I HAVE turned monitoring on) .
e.g. my top process after 3 hours is Beautiful live Weather at 1.8% then system at 0.4%? surely that's a bit low, if I add up everything in top processes I don't even get 10%.... also I'm sus as none of the blur stuff is showing up LOL, also I've been listening to music via BT for at least 1 hour and its not even showing 1%....
My drain is not crazy (~5% an hour if mostly idling, ~10% an hour with BT music) but I want to improve it

I do believe motoblur is included in "system"
About the percentages... is it the ammount of total battery used, percentage of processing capacity, or what? You have to look out for those details.
even if it is total amount of battery used, where is the drain caused by 1-2 hours of mp3 playback via bluetooth? surely thats on the list somewhere. I know for a fact that it doubles the rate of drain roughly.

well dont worry, i too now have this awwake problem. last night 9 hours unplugged, all while i was sleeping so no phone usage by me, my phone was awake constantly, just a thousand little awake blips on the graph.
so i check system panel, and it all shows as normal. nothing high usage or out of the ordinary. so something else is going on here.
i'm a religious system panel user too. never had the awake problem on my nexus one.
Hi,
I got my second android phone (LG G2 obviously) this christmas, and I haven't had time to properly use it (I don't have a micro SIM yet). I noticed that my battery is going empty pretty fast, although I heard this phone has a amazing battery. My friend got this phone too and he told he's been on one charge for about 36 hours with constant wi-fi connection, app downloading, playing games etc. so I figured something's off. I charged the device before going to bed and when I woke up (10 hrs later) battery was on 85% (only 2 MINUTES of screen time!!!!) and I had no apps running on the backround, no nothing. So now I'm thinking is there some easy fix for this or should I return it and get a replacement? Also something weird I noticed yesterday was that even though I don't have a SIM card yet, but 16% of the battery was used by the phone application. I did some screenshots of battery usage today and yesterday too if anyone's interested.
There are literally dozens of similar threads... suggest you start searching.
And I literally have gone through 90% of them so I decided to start a new thead. Do you (or someone) think that a factory reset could help? And the next question might sound stupid, but if I do a factory reset then does the warranty remain? Better safe than sorry I guess
I just played 4 minuts of hill climb racing and lost 3% of my battery, this is not normal. Does anyone even have a solution for this? All I see on other threads is questions and questions, but I don't see anyone saying "That worked and my battery life is normal now"
It's normal if screen is bright. Especially if carrier bloat is still there. Post screens, all you have, and what carrier. The phone could have been sick in a search state.
I don't think my phone is tied to any carrier, it was bought from just a regular electronics shop, but frankly I did a facory reset and didn't realize that all my screenshots will be gone too. Do you really think it's normal that 10 hrs of idling causes 15% battery loss? And it has the stock LG apps (safety care, life square, cell broadcast etc.). What do you mean by "The phone could have been sick in a search state."? My screen brightness is on 70%.
It's normal with bloat in it. They all have bloat stock. 70 is high and can eat at the battery pretty good. I mean it could have software glitched and was struck searching for activation behind the scenes. Use Wake Lock Detector and see what is keeping it awake.
This, almost 20% drop was caused by downloading 3 apps (facebook, facebook messenger and twitter), updating ~10 apps (all done via wi-fi) and rearranging my home screen.
Steamer86, are you sure? My friend told me that he has been 36 hrs on one charge without changing any settings and just downloading apps, playing games and testing the phone.
Your idle is great at that point in time. Facebook is a battery killer. That's a lot of activity with 70% brightness all the time. It's 17% and medium higher side usage and an hour+ of screen time. What are you expecting? At this rate with 70% constant screen and Wi-Fi pushing pretty good you would get almost 6 hours OST. That isn't bad bud.

This night i lost 18% of my battery and my phone was almost all the time on deep sleep.
But i did notice something weird, battery usage shows that Android OS is using up most of my battery and when I press on it and then hit the back button then the Android OS changes to something called surfaceflinger for a millisecond (check the screenshots)

Can you try putting your phone in airplane mode and then turn on Wi-Fi? If you aren't using a cell carrier than there's no need to keep that on.
See how this works in increasing battery life for you.

Has anyone else noticed a decrease in battery life since the 4.4.2 patch?
At first it seemed comparable to 4.3 battery life: 6-7 hours of screen time with Chrome:The Battery Hog. It also didn't discharge AT ALL when idle. Maybe 1% overmight or so. That is with most programs set to sync hourly and wifi off when screen is off.
However, I've let it fully discharge one time from 100% to 0% battery. It turned off and i immediately put it on the charger. I cant remember if it was since then or a few charging cycles later (100%-15% ), but now it uses a lot when idling: around 5% per hour or so. Screen on time is also terrible. See screenshots for details.
Can you guys share your thoughts on this matter?
More than likely it is your Google Play Services that are killing your device. This issue has been occurring ever since 4.4.x
Is that fixable or do i have to wait for a new update?
Also, I remember that the battery drain started when i connected to a friends phone to tether via his phone over wifi. Does that have to do anything with it?
I cleared data on Google play services, and put my location settings to battery saving. The GPS on all the time drains the battery. With moderate use, I'll last about 10 hours.

My video playback battery life have dropped significantly since I updated to from 4.3 to Kitkat
details can be found here
The following are using MX Player Pro, H/W+ Hardware acceleration, 720p videos( in 16:10 aspect ratio to fill the full screen). I seen no visible change between 4.4/4.4.1/4.4.2 AOSP in battery life.

I keep my brightness almost all the way down. And I have location services, and always listening turned off.
Okay so ive had another cycle. Now, it drained 10% overnight. The screen on time seems okay but ive switched to art with this cycle, and ive seen people get 10+ hours with that.
Im going to try to delete google play services data as you suggested, but it doesnt use as much battery, as you can see in the screenshot.
Android system and Media server seem to use the most energy, though at the time of the screenshot, 80% of my screen on time was whilst using chrome. Also, theres this process called com.android.chrome:sandboxed_process4. What is that? I have googled it, but to no avail. Ive seem multiple imstances, ranging from 0 to 4, in my battery usage list.

Yes, I am. Thanks. I will give it a try.
Or install app ops since you're rooted and disable keep awake for all android stuff, especially Google play services and Android system . For some reason Googles devs thinks drainage is less important than whatever they do but fortunately we can adjust their mistakes to our benefit. I get 3 days 10+h SOT. When the Google devs push out an update for something outside of play store "android OS" usually keeps awake until a reboot is made but luckily it doesn't happen too often.
And also, use a superior browser. I recommend Next or Dolphin.

At my age (15) I do not have much experience in developing/understanding how operating systems work but I'll try to explain it in a way that is understandable:
Android and pretty much any modern operating system has a way of "sandboxing" applications or programs. Basically picture a sandbox with sand in it. The sand cannot escape the sandbox because it is around that box. (This is where we actually get the term 'sandbox')
When Google was designing Android, they basically made an implementation into the system that reduces the frequency and impact of application security issues. With that being said, this was made so you can use the default file systems and such without harming the system itself. If you were modifying the system, you could potentially open your device to a exploit. The sandbox features come into play so it can isolate your application from other applications. If it wasn't like this, any application could execute code to steal data/code from other applications. You can still do this with exploits in the kernel and such, but it isn't as easy as it seems.
You may have heard of the software on Windows called Sandboxie which is designed to to prevent "permanent changes" changes to your system, files, etc. It basically separates the system from the application itself. It is commonly used to test to see if software that you have is infected. In short, this is similar to what Android has.
--
The site I linked you in my other post basically explains how Android creates these processes in a more technical manner. But that link was specifically for Google Chrome, but it can be pretty much used in any other application if needed.

I would suggest greenify and put everything but the system to sleep and see if that does it for you. If you unlock the bootloader, install TWRP, root and install a custom ROM on your tablet you can use a custom kernel and adjust (in layman's terms) the power your tablet consumes and when. You can remove some of the system apps you may not use and cut back on ROM usage too. Google adds all kinds of apps to the system that will function just fine as user apps.

What bugged me was the disappointing battery life when the screen was turned off (not completely powered off of course). Even in airplane mode it would die in a day or two just sitting around. Battery stats showed Android System and OS were killing the battery. I never figured out if there was a setting or something to fix it.
Instead I loaded Cyanogenmod 11 on it a week ago and now it uses only 3% of the battery a day when I'm not using it. I don't miss any of the Samsung extras.

Something must be keeping it awake. My tab has excellent standby battery life.
Doesnt lose more than 5% in a day. I do have the setting to turn wifi off when in sleep mode though (unless plugged in)
Battery life on the whole varies. Video watching through the stock video player drops about 10% an hour. Surfing would depend on your browsing habits. Gaming drains close to 20% an hour. Pretty standard. That along with the excellent stand by time means I get about 2 days of use on a charge.
Every day at work telephony, internet, email, IMO 24hours, 24hours Bluethooth Gear 2 connect. Dinner consists of my tablet battery 55%. For me life is great. My tablet root and frozen Samsung Apps (Bloatware) ... XDA .... Try the Nova launcher from the Play Store to Improve speed. Set it as your default launcher then Disable / Turn Off;
Flipboard, MagazineWidget, S Voice, Samsung Apps, Samsung Apps Widget, SapaMonitor, Screen Saver, World Clock, and (Hancom, Office for Android Share, Hcell, Hshow, Hword, Updater, Viewer Launcher, and Widget) if you do not plan on using it.
We will be adding Quadrant test 24,000 points on the original ROM.

Yes it was using as much battery as watching a movie with the screen on. Something was terribly wrong with it. I think this behavior started after a software update I got from Samsung.
I turned everything off including Wifi and it was still eating the battery while sitting there with the screen off. I have never seen that with any Android device I've ever owned.
But I'm happy with Cyanogenmod. Battery life is outstanding now.
My battery life was mediocre, and then I put cyanogenmod on, and it went to dreadful. With the tablet at 100% and OFF, untouched, it would be 20% down in 10 hours. In contrast, my iPad loses maybe 3% in that time, doing the same thing - tracking email.
I ran a wakelock tracker and noticed that Exchange Services has it awake about half the time. The total time. Like in 10 hours Exchange had it awake (with screen off) more than five hours. Effen ay. Something is seriously screwed up with how Cyanogenmod's Exchange talks to the two Exchange services I use. Switching from Push to "5 minutes" has helped significantly; Exchange is still the worst culprit, but now only by a factor of four rather than a few hundred.
Ideally what I'd like is the new Exchange apks modified to prevent admin and fixed to be less wakelock intensive.

Something must be keeping it awake. My tab has excellent standby battery life.
Doesnt lose more than 5% in a day. I do have the setting to turn wifi off when in sleep mode though (unless plugged in)
Battery life on the whole varies. Video watching through the stock video player drops about 10% an hour. Surfing would depend on your browsing habits. Gaming drains close to 20% an hour. Pretty standard. That along with the excellent stand by time means I get about 2 days of use on a charge.

What is your on-screen time during the 2 days?

Cyanogenmod has their own version of Exchange?
Our Exchange servers at work are ridiculously slow and unreliable. They can take two minutes to return your mail which is a major drain on your battery if it's set to check it every five minutes and you get a lot of mail. Sometimes they'll just stop responding and leave you hanging. The IT people just tell you to keep trying and you'll get your mail eventually.

Dunno.. 7-8 hrs I guess. Screen on time really doesnt mean much without any context.
I can get 12hrs+ watching videos on 20% brightness. I can kill it in 4 hrs playing games at 100%.
Like I said, the standby is excellent. Drains less than 10% in 2 days. So for me, I have about 90% to use over 2 days.. and from my experience,
video drains less than 10%/hr
gaming ~20%
reading books drains less than video.
General surfing, mails, social networking uses between 10-15% depending on how you are using it.
My brightness is usually around 40%. Goes up rarely when I'm using it bright conditions. Goes lower when I'm reading late at night
Should give you an indication of what you can expect from the battery depending on your usage..
Mine drains about 10% per hour while constantly using the device for light tasks, such as reading, web surfing, and watching some YT videos here and there. That increases to about 15%/hour when I watch movies. So after watching a 2 hour movie, I expect to see about 70-75% of battery left. Now if I'm listening to music for an hour at the gym with the screen turned off, it only drains about 3%.
At first, I thought that was pretty mediocre and felt disappointed. But I've taken my tablet with me on many trips and never had it die (usually just close to 20%). I rarely ever use my external battery pack. I know this will vary depending on how long the trip is and how much you're using it, but I'm just saying that it meets my needs despite having a lower battery life compared to some other tablets. I do all I can to extend it, but I don't have to constantly watch it.
Last night I charged the tab 100% and with Wifi off (sync for 1 min every hour. )
Today the battery is at 71% - On battery 13hours - 44 mins
27% Android OS
24% Google services
13% Android System
8% Onscreen time - 20 mins
Should I flash CM to fix this?

CM won't fix that. Install Better Battery Stats or Wakelock Detector to nail down the precise problem. If you're using them, it could be Exchange Services or Google Drive (yeah, that turkey wakelocked me to oblivion!), at which point you at least know what to attack.
You can find BB on XDA here and WakeLock Detector on XDA here, both are also in the Play Store.

Google search with 23 mins of wake time and Gmail with 6 mins.
Currently Deep sleep is 14 hr 26 mins. Total time is 17h 5m. Awake is 2h 39m. Screen on time - 27mins.
I added the google now widget a couple of weeks back and that caused some wakelocks and overnight battery drain. Removed it and didn't have the problem.
The battery life is pretty good for me. Was out a lot, so had wifi off for large parts.. watched videos (from device), read some books, played some Asphalt (not much.. around 30 mins) and some browsing/mails..
Got 11 hrs screen on over 2.5 days and still have 15% left.
Yeah was indoors so the brightness was never over a third (~30%) and reading books really doesnt drain much battery(especially if its at night and you turn the brightness further down)..
I'm not saying people will get 10+hrs screen on with their device and usage constantly.. 8hrs would be realistic.. but the point is, the battery is a lot better than I had originally expected.

I have this same problem - except my GTP is 100% stock, unrooted. I can go into Settings/Battery to see that Exchange Services is chewing my battery. It will die in less than 24 hours, even if I don't use it - as long as it has a WiFi connection. I think if I turn off WiFi, it will stop attempting to sync and the battery will last "normally". I don't know for sure, though, as I haven't tried. I'm not interested in a tablet with no network connection or even without my email.
I'm going to cut a VERY long story short (at least, here) and say that I have spent several hours logging the ActiveSync traffic between my tab and my server, poring over the logs, and I have identified the problem. It's one particular item that is failing to sync, which causes the tablet to retry the sync every 1 second. The sync failure causes the server to log an internal server exception every time - despite the ActiveSync requests from the tablet being correct. I also found a Microsoft KB article that appears to address this exact problem, and MS has a hotfix available for it.
I have talked to Tech Support at my hosted Exchange provider and they have confirmed with their operations staff that my server does not have the MS patch that is referenced in the KB article installed. Unfortunately, they are giving me a bit of the runaround on installing it. I only have one mailbox hosted with them, so I have no pull. They sound like Verizon. "We have to thoroughly test this update in our lab before we can install it on your server." And "nobody else has reported this problem and we can't put too much time into a problem that only one user is experiencing."
So, I am now just waiting for them to install it on my Exchange server and see if it really does fix the problem for me. If it does, I will be posting about it on XDA and the AC forums, as a Google search showed me that a lot of people, with a lot of different Android devices, have this same problem and nobody seems to know what's really going on or how to fix it. I will try to remember to post back in the GTP General subforum specifically, too, so stay tuned.
My battery life seems to be getting better as the battery gets some more charges on it.
Sounds basic / silly, but i simply put mine in battery saver mode and that made a big difference with little effect on performance
