Battery

Hi all! I've had my note for about a month with no problems, but last night it went flat in 11 hours of no use.... The battery use screen shows that it was the OS with nothing else running!

I have this problem too, really need to know answers!

Do u leave ur wifi,packet data, gps and Bluetooth always on? This may be the problem,just use any battery saver tools and close unnecessary hardware

wifi - yes
packet data - dunno
gps - no
bluetooth - no
but i always have the same settings - why such a sudden drop in battery life?

Check if you are in 3G mode or 2G.... 2G save a lot battery
Im happy can reach 5 to 6 hours screen on

Installed anything just before the drain problem?
Pretty much all the problems I've had with battery drain have been traced to an app misbehaving. The battery stats info can be a bit misleading too - so don't trust that the OS itself is draining the juice... Its more likely to be some service app that doesn't show up a itself on the stats.
I've found Widget Locker a painful battery hog, for example, but it never shows up in my battery stats. Instead the Android OS, or whatever last write to the system log (log cat) show up as using all the power. Uninstalling WL always fixes the problem so I know its that app causing the drain.

Also, is that shield in your notifications bar some sort of battery saver?
If so it may be the cause not the saviour! I've read that the latest free version of Green Power tries to connect to ad-servers constantly and drains the battery double-quick. Apparently the premium version doesn't have this issue but you have to pay for it, obviously!

the issue is undoubtedly running services..you probably added an app or three that is high maintenance.
shut down and restart your phone and then without starting or using any apps, leave it overnight to get a better benchmark for battery life.
If still low, look at the running services, you may be staggered to see what amount of crap is running in the background..

how do we find what services are running?

Mine hasn't had any new apps installed and normally loses about 7 percent overnight. The shield in the pic is lookout which I've always used without a problem. I have restarted the phone so I'll see how it goes today. Its wierd because nothing has changed in use or apps so something must have hung and run it down.
I'll post any other findings!
Thanks
Steve

just done a hard restart
turned off wifi
removed weather widget
removed live wallpaper
turned off haptic feedback
will test results later

Note 3 WiFi drain when is on

Hello everybody
I have problem with battery drain when my WiFi is on. During night my battery drain 1-2% which is great and WiFi is off, but when I turn my WiFi on and just read news with some app it goes down 5-10% in like 10-15 min. I'm not rooted because he is still in warranty and I don't wanna lose it just yet.
I've searched the forum and I have just found that people have problem when WiFi is off and battery drain like is on but that's not problem here.
Any suggestion?
Thanks.

To diagnose this you would need an app that monitors what it is that is draining the battery.
Try installing "Better Battery Stats," open the app once then close it. For a few hours, use your phone like normal or in a situation you want to diagnose. Then go into Better Battery Stats and post a screenshot of "Kernel Wakelocks," "Partial Wakelocks," and "Other" here so we can take a look.
Better Battery Stats: http://forum.xda-developers.com/attachment.php?attachmentid=2411941&d=1385305325
Other apps which are good to see what is draining the battery are GSam Battery Monitor and Wakelock Detector.
GSam Battery Monitor: https://play.google.com/store/apps/details?id=com.gsamlabs.bbm
Wakelock Detector: https://play.google.com/store/apps/details?id=com.uzumapps.wakelockdetector
Do the same with these apps as I said with Better Battery Stats and post screenshots from them.
Good luck!

Thanks for quick replay. I'm using GSam Battery Monitor for 2 weeks now and here are the images I think it could helps.
If you need something more just ask.

Those pictures look pretty alright. I'd say you aren't suffering from the Android OS bug a lot of other people are suffering from. What is your screen on time? 32% battery left after 6½ hours is quite a lot of drain, it seems as though you must have had the screen on almost the entire time. Looks as though Facebook and Google Services are the ones draining your battery. You could uninstall or deactivate sync for Facebook for a while and see. Google Play Services issued an update some day ago which is rolling out which should fix battery drain as well. You'll have to keep a lookout for that one.

[Q] What is draining my battery

Hi All,
For the last month I have major problem with battery life.
While the phone is NOT in use (like over night) it drains almost 10% per hour.
I didn't install any new APP. The ROM version is Samsung stock 4.3
I installed 2 Apps GSam Batter Monitor and Wakelock detector.
As you can see in the screen shots the Kernel is the major consumer (about 90%).
I will appreciate your help.

Antivirus, task killer/clenat etc?

Thats realy bad... Disable all GAPS (except Gmail and Play Store), any unnecessary apps (Task killers, AV etc). Let the battery go down to 5%, turn off the phone and fully charge it. Try WakeLock detector if no improvement.

Back up your stuff and reflash the FW. I would suggest using KIES 3 and in Tools option Emergency Recovery. It will completely wipe your phone and flash latest FW. When finished, boot up phone but don't set up. Do hard reset (either via Menu or use the 3 key combo) and you should be ok...

Delete it. Its a bad app. Do only battery draining. No more Because android its not the same like windows
Or battery is old.

Either your battery is so old that it's just had it, or you have a serious issue somewhere.
Why has no one suggested the app 'Better Battery Stats'? Install that, charge the phone to full and when it's at 5% screenshot the stats and/or save them and come back and post them here.

i'm also have problem with battery drain issue and after checked with wakelock detector app here Wakelock detector
it was wechat app that have wakelock several time say 2000 times a day.
then i used xposed name per app hacking to prevent app wakelock and it solved my problem..

Hi,
I already installed wakelock app.
Here is screen shots.
Please advice.
Thank you

Your wakelock is kernel related. It could be GPS, bluetooth, using the wrong governor...there are so many things that it could be that it's impossible to guess.
Use Better Battery Stats as has been suggested. It gives a much more in depth report of battery use.

Yeah,it's hard to guess when related to kernel...mine is related on app itself

[Q] My S5 have deep sleep 90% of the time, but the battery still lose like 4%/h

Hi all,
Please help to move the thread to a suitable place if this is not the right place.
As the title said, I have my phone deep sleep like 90% of the time but the battery still lose 4%+/h.
Does any one have any idea how this is possible? Thank you in advance.
Attached is my BBS dump.
Appreciate your support!

May be some apps are running in background, which is disturbing your device to have deep sleep..
Use Wakelock detector app to observe which apps are main culprit..

[Q] battery drain already?

Hey guys. First proper charge from around 3% too 100% and I'm getting battery drain already, I thought this issue was resolved in lollipop? Not the mention the emense heat that comes off of this device
Check out the picture and get back to me. Thanks.
Jack

Same thing is happening to me... I don't find that the drain is really so bad, as I still get pretty great battery life, but does appear that this issue is still present in lollipop. Seems pretty wide spread among Android users.

I had an iphone for about 5 months. Went back to android and the problem still persists I got 3.5 hours of screen on time yesterday. Take a look at this

Also getting battery drain, the main offender seems to be the "mobile standby" which is always around 50-65% for me.

I think this was an error in reporting in the stock firmware, I haven't had a problem with the battery, in fact it's been really good. Since updating to B132 (GRA-L09) the battery usage seems to be reported correctly.

Interesting, I'm not sure what the normal drain should be then. My HTC One had a pretty good battery life, but it seems with this phone the battery drains quite fast when I'm using Chrome and WhatsApp etc. The power saver reports Chrome uses a max of around 10% but the rest use very little %, yet it seems I'm using around 30-40% of the battery in around half an hour.
Do you think using a custom rom (when they become available) would be any different?

Not sure if a custom rom would help. Are you rooted? If so you should have a look at betterbatterystats which should show you what's using up the battery.
When I'm mostly on wifi I can get 5 hours of screen time with 32+ hours running time.

i have the same problem with the "mobile standby" batery drain
i did a clear data/cache then factory reset, and now it's ok
androyd system still drain batery pretty much
sorry for my bad english

Was going to wait for a few roms to be released before rooting, but the battery life seems so poor I think I'll do it just to find out.

I've had the same Problem with the battery drain and analysed this with the Wakelock Detektor (needs root). Cause was the "NlpWakeLock" thats part of the Google Services. Then I disable the Google Location History everything went well. They are a lot of of useres, who have the same problem. The only real solution (If you want to use the Location history) is a Xposed module for that you need a working Xposed framework.

I have now disabled Google location history, hopefully this fixes the problem for me too.
