Battery drain problem/sensor usage

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.

Severe Battery Drain from "Android OS"

Anyone else having this problem? All the sudden Android OS is taking a ton of battery, killed half my battery overnight while the screen was off. Anyone have any of these problems?

Android OS is too general to say what is causing the wakelock. Use an app that can see which process is causing the wakelock directly and you will know what the problem is.

Then you definitley have an app or two that is causing it. Try CPU Spy (let's you know if you get deep sleep or not) and see if that helps any. I hate battery drain so best of luck in solving your battery drain issue.

Since I've upgraded to 4.2 roms on all my devices I've noticed this too. Normally, Maps is the culprit causing a "normal" wakelock. Google +, Latitude, Google Now, etc. This is just the way Google operates now & the biggest difference between 4.1 & 4.2. I've taken to disabling Location unless I'm needing GPS service. It checks your location every couple minutes it seems.
I've had a situation you describe a few times caused by media storage. It keeps scanning the SD card. Sometimes a reboot helps but mostly I've just changed roms instead of chasing it. Better Batt Stats should show it somewhere. Keep looking, look in "alarms". Also you might try GSam Battery Monitor. That app has come a long way lately & also helps finding battery sucking sources.

For me it was Viber. After deleting it I get almost no battery drain over night. Maybe 1% in 8 hours...

[Q] Screen destroying battery

So I just figure I'll ask about this, but I have a feeling people will suggest I wipe and I just don't have time to do that anytime soon... But it appears that my screen is absolutely destroying my battery life. I keep the screen off whenever I'm not using the phone, but just now in 6hours on battery i'm down to 69% and 57% of it is all screen. The next biggest is 11% on Android OS. Just doesn't seem normal right? Any ideas?

Screen wil always be at the top of the battery list in Settings, if it is not there is something seriously wrong.
One thing you need to understand; the percentage listed there is not the actual percentage of drain. It's how much of the actual percentage is caused by those apps/systems/hardware.
So 57% screen means that of the total drain, 57% is caused by the screen. The total drain is not 57%.
Try using BetterBatteryStats and Wakelock Detector to find out what is really draining your battery. You can find them here on XDA, and on Google Play.
Do you have autosync on? What wallpaper? Location services?
Send From My Samsung Galaxy Note 3 N9005 Using Tapatalk

All my syncing is on yea, just a plain wallpaper, not a live one, and I have Access to my location and use Wireless Networks checked in location services. GPS is off whenever I'm not using navigation. I'll check out those apps. someone else suggested batterydoctor so I'm playing with that one right now, not that it's really telling me anything except to kill apps, which I know is against the general consensus on these boards (killing apps manually)... And of course it says to turn my brightness down or to auto, which I don't even like the phone when it's not on full brightness so that's a no go.

[Q] Android OS accounting for a huge part of battery usage

Hello all.
First off, bear with me if this has been discussed before, I have searched on google and in previous threads here (including the amazing 58.5 hr standby and 6 hr. usage thread) but I cannot find the culprit of the huge Android OS drain.
The battery lasts about 4.5 hrs of screen on time , which is pretty neat but nowhere near what other people are reporting. I know the battery needs to go through a few cycles before reaching its full potential, but the Android OS drain is what bothers me. Please note that I am unrooted due to warranty issues and an unreliable rootchecker.
I have done the following:
Disabled bloatware
Disabled LG MIT (P.S Do you recommend me to change other settings from the hidden menu?)
Disabled auto sync and backup in the settings menu.
Disabled Google Location services from Google Settings, although I kept the location settings in the settings menu due to widget.
I installed Lux to prolong battery life and it only operates upon waking the device.
Installed BBS and Wakelock detector
BBS shows 154 partial wakelocks in just 3 hours of standby from WifiOffDelayIfNotUsed and NetworkLocationLocator 191 partial wakelocks.
Wakelock detector shows a fair amount of Facebook wakelocks (86 in 3 hours - could that be the culprit?) and Viber with 21 wakelocks. This makes me miss Greenify - damn!
To round this off, can anybody please give me advice on how to solve this drain? As previously mentioned I am not willing to root it just yet. Feel free to include perfomance boosting tips as well if you have any
Thanks in advance.

I don't know how to solve the problem, but I can tell you this regarding root: Flashing a KDZ file after doing a full factory reset makes the roottripper reset too, including a showing of UNROOTED in the download mode.

Awesome news! Makes me reconsider rooting my device. I would still want to know what I can do without rooting. Thanks a lot for the info ?

Use Better Battery Stats to see exactly what is causing wakelocks and GSam Battery Monitor to see what's using other things.
"A huge amount of battery" is meaningless without context. If it says "50%" but that's .5%/hr, it means NOTHING else was doing anything really.

Disable KnockON, then Android OS will shrink to a few percents in your statistics.
I have tested it out, KnockON is causing the most part of Android OS.
Via LG G2

Wifioffdelayifnotused can be caused by going in and out of service. Disable optimizing in Wi-Fi, disable disconnect on low signal, set sleep policy to never.

well. As stated in OP I am using BBS but I will try out Gsam battery.
You've got a point there, but I'm not seeing 24 hours of standby, which annoys me. A side note- if there was no' something' draining my battery wouldn't it show as "device is idle" rather than android os?

Thanks for the tip. I am well aware that knock on uses up some battery but I don't recall the people getting 6 hrs of usage and 50 hrs of standby disabling this feature. Anyway I wouldn't disable this feature even if it would give me am extra hour of usage (unless in dire need) ??
And to the last post (which I forgot to quote) WiFi is set enabled in standby and the other option is disabled. The only thing I have checked in the advanced WiFi settings is lower battery consumption when device is using WiFi. Thanks for clarifying though.
It seems like. Android os is a mystery ?

Delete.

The cpu power consumption is the biggest problem~
I had read a Chinese thread that CPU quality is the major problem causing this huge battery drain. Qualcom classified 7 quality levels. Slow, nominal, fast, very fast, ultra fast,....from class 0 to 6.(higher is better). the higher class quality means that cpu can use lower voltage to reach higher frequencies. The difference between C 6 and 0 is about 0.15V,,, :crying:
PS: [email protected](0.95V Max)/ [email protected](1.1V Max)

There has been some improvement but the phone was awake for 42 minutes more than screen on time . I posted some screenshots.

I'd say leave wifi optimization, set sleep policy to any other than never, and turn off the feature that turns wifi off if the access point you're connect doesn't have internet access. Or try aosp

If you're connected to more Wi-Fi than cell signal, leaving this on will do nothing to increase battery usage, more so increase it. Counterintuitive, but it is what it is. This is Google software itself, not hardware. Learn before you post BS. The phone uses more battery searching and refreshing for 4G data signal than it ever will on Wi-Fi. Do what this guy says if you spend most the day in Wi-Fi, and watch those counts hit the roof. If your of Wi-Fi most the day, just turn it off until you are, all good. Why waste battery when unneeded.

Awake with Screen Off percentage

Hi All,
I currently own a Nexus 6P and was find the battery life OK.. not great.
Lasts me the whole day but did expect better considering the size of the battery.
I recently installed BetterBatteryStats - my device unrooted and with stock rom etc. so the detail the app could give me was limited.
But from the screenshot attached you can see that at about 20% battery after about a days use - with around 4hr SOT - it shows that 34% of my entire battery usage was when my screen was off.
Which is more than the whole time the screen was on.
Now, I did use Apple Music on my way to and from work on this day which according to the app had a CPU Total time of around 45mins - so could probably minus that from the awake with screen off stats.
Nevertheless- this would still be a massive amount of the battery usage.
In terms of config of the phone, I have wifi on always on, bluetooth is off and bluetooth scanning is off, wifi scanning is on and location is set to high accuracy.
Was just wondering if anyone else had used this app or similar to get their daily stats. Would like to know if there is possibly an app on my phone which is draining my batter faster than expected.
I've attached additional screenshots as well all taken around the time.
One last thing - one of the screenshots attached is something which keeps showing up in my battery stats - Media Server. I have no idea what this is but any knowledge on that would be great.
Thanks a bunch!

The phone calls may also count towards your screen off drain in better battery stats? Honestly 4 hours is about the average screen on time for a stock 6P. I expected it to be more too. I wouldn't worry too much about Media Server unless it's really chewing up battery. It will run when you're playing music.
