Umm my notes battery lasted me for about 6-7 hours before. But now when I charge it to 100% overnight and then go to school nd come back at 6 then the battery is 40 something percent…then I check what’s using the battery up by going to the settings nd I see that the android OS is using up the battery the most…I still have have the warranty and everything..This started only recently..awhile ago I used my note while it was charging extensively… Is this the problem?? Can someone please help me?!?January 8, 2013 at 1:54 pm #691
Yes, the battery has a life span of a few years for moderate use. Usually, the battery will lose considerable capacity after 500-600 cycles. There is another thread on this battery issue: https://www.allaboutgalaxynote.com/topic/note-battery-issue/
In most regions, the warranty for battery is only 6 months (while the note normally has one year warranty).
So, you may try to get a new battery if you used it heavily before.January 8, 2013 at 3:43 pm #692AnonymousInactive
ooo but my phone was bought about 3 and a 1/2 months ago… How can it be that it suddenly stopped working to it full capacity? !? Also I looked at that thread and I don’t think my battery is bloated in some places…it just is draining really fast…is it some system problem??because when I go to the settings and look at what’s taking up my battery it just says android OS… Is it because the phone is not going into deep sleep mode?? I also have juice defender and previously the battery decreased by like only 20% in the same time frame and now it’s like decreasing 50 percent… I don’t know what to do.. Even if I exchange the battery will it even affect anything?? Please answer fast..January 9, 2013 at 11:10 am #695
You may try CPUSpy and BBS as explained in this post. I had thought you haven’t found any issues in deep sleep.
Sometimes, if the issue was caused by system, you can try to reboot your phone.January 9, 2013 at 1:59 pm #696AnonymousInactive
ah well I used cpu spy and nd it said the only unused state was deep sleep mode.. Most of the time it was 200 ghz for like 85% nd the rest was 500 ghz… I read that article nd that is not what is happening… It’s just losing battery nd the battery is relatively new as well.. The phone is 3 months old… Also with bbs there aren’t any major apps which take up more than a few min in the partial wake locks and the highest 30 min… I don’t know what’s happening… Also I went to battery in settings and then I see that the android OS is taking 38 percent up.. So what is the problem?? Also this was a period of 13 hours with the Internet on… Before it used to be that my battery lasted me for about 2-3 days if I barely used it.. Now I need to charge it every night… Can u please help me?? I live in hyderabad India.. I got this from reliance digital.. If u live in India u would know what reliance digital is.January 10, 2013 at 12:24 pm #704
It seems your phone cannot enter deep sleep state. When your phone is not in use, it is supposed to enter deep sleep mode. This is probably the major reason of the battery drain.
You may try to shutdown the phone, remove the battery,, wait a min, then put the battery back and power on the phone. Now wait a few hours, and check:
1). the reading of CPU Spy
2). reading of “Others” in BBS
3). reading of “Partial Wakelocks”
4). reading of “Kernel Wakelocks”
If you cannot find the problem, you may post the reading in this thread. We can try to help you figure it out.January 10, 2013 at 1:13 pm #706AnonymousInactive
Umm can I please have a email on which I can send the screen shots to? Because I am not able to post it on this… Umm I will do that and I will get back to u by tomorrow and give you the following details which you requested.. And you are right… My phone is not entering deep sleep mode at all.. I checked on cpu spy… Please tell me the email as I want this to start entering deep sleep mode fast.. I will send the pictures to the email by tomorrow at this time.January 11, 2013 at 11:59 am #707
For BBS, you cna dump all info into a file: tap the menu (left) button, go to More, then choose Dump to File. The info will then be in a text file in /sdcard (the top folder you can access if your phone is not rooted).
You can send us info with attachment through this page: https://www.allaboutgalaxynote.com/feedback/January 16, 2013 at 2:41 pm #711AnonymousInactive
I could only send the cpu spy attachment as the bbs attachment wasn’t sending.. I don’t know why because it was a text file… Umm could I have a email or something please… And if u saw the feedback form you could see that it was only on 200 mhz for like 58%…There must be some process or app that’s keeping it from going into deep sleep mode.. If I could have a email which I could send the bbs stats to u to that would be great.. Btw sorry for replying this late…January 17, 2013 at 12:17 pm #713
I didn’t receive your message.
anyway, please send the files to: feedback AT allaboutgalaxynote.comJanuary 18, 2013 at 12:43 pm #718
Hi Puneeth, I received your BBS log. Apparently, your phone failed to enter deep sleep state because of the following kernel wakelocks:
1. "suspend_backoff" (): 6 h 31 m (23460 s) Cnt:(c/wc/ec)2349/0/2349 51.0% 2. "alarm" (): 4 h 55 m 24 s (17724 s) Cnt:(c/wc/ec)332931/0/0 38.6% 3. "l2_hsic" (): 3 h 28 s (10828 s) Cnt:(c/wc/ec)21943/0/21942 23.6% 4. "sec-battery-monitor" (): 2 h 9 m 17 s (7757 s) Cnt:(c/wc/ec)21654/0/0 16.9% 5. "deleted_wake_locks" (): 52 m 57 s (3177 s) Cnt:(c/wc/ec)15409/0/178 6.9%
Based on the processes, you may try:
1. stop JuiceDefender
2. stop Chrome
3. stop the antivirus;
(you can stop an app by Settings–Applications–downloaded, find the app, then choose Force Stop).
Please let us know whether it works.January 26, 2013 at 5:47 pm #734AnonymousInactive
