Hello... I noticed that there are periods when my battery drains relatively fast and saw in betterbatterystats that suspend_backoff wakeups keep the CPU at 300 MHz preventing the phone from deep sleep. I came upon some threads claiming that Google Chrome is the culprit, but I don't keep Chrome running in memory...So anyone has any suggestions?

My rom is V30B - stock. I uninstalled Chrome and Google plus and haven't seen suspend_backoff wakeup poping up in BBS.
Now install only google chrome and report back.

There are plenty of threads concerning battery life. Search and read. Download "cpu spy" from market so you can see if your phone goes to sleep allright.
Uninstall failbook or atleast keep it from updating every three seconds or so. Etc etc etc.
I have installed cpu but can u tell me how it works? Very confused on how to see if theirs a problem. My reboots i think are from facebook so ive deleted that app.
Cheers

To use cpu spy....
Reboot your phone... Turn off the screen for few minutes... Then check deep sleep state in cpu spy.....
Has anyone tried the bigger batteries that you can get. Spotted some on eBay and amazon and wondered if they were any good.
I knot with some you get a replacement back as it increases the thickness of the phone but I don't know if this is a worthwhile trade off.

I used stunner and I used to get 2 days plus with normal battery with moderate usage. Now iam getting 1 and half day with AOKP.
For CPU spy - see if u get deep sleep.
Also chk out with Badass battery monitor which app using the most.
Lol first analyse root cause. In an hour of non activity and not on charger pecentage deep sleep should be approx 80% two hours 85-90%. Figures based on clean rom, nocrapware and no rediculious settings. Thats one, two how long does your battery last when using phone nonstop? 2.5 to 3 hours is normal. 3-4 then you know what you are doing 5 youre a guru.
Lmao
If your cpuspy figures are lower then above then with better batterystats you can find kernel and partial wakelocks. Google them and find out whats keeping your phone awake.

Hello,
since flashing to b39 im having a rather high battery drain of about 2-3% per hour, when my phone is in my pocket. bought better battery stats, which shows many partial wakelocks coming from syncloopwakelock.
i am using semaphore 1.2.2, standard settings.
do you have any ideas to fix this?
with kind regards,

Depends on what you did during that period.. If the processor was running at MAX frequency the entire time, yes thus might be normal.. Also as I notice from the screenshot, the screen is always in in that time frame.. So you deduce from this

No. It's broken. You should send it to me.
Hi,
Thats an abnormal drain. Try restarting your phone and seeing if the problem persists. Also note that the ROM you are using is still under testing and not a finished product so might experience some difficulties. Consider shifting to a more stable ROM if problem persists.
Having said that, battery drain will depend quite a lot on what apps you have running in the background and your settings.
Best way to analyse the situation is by installing an app called 'Better battery stats'. Its by a XDA member and if i'm not mistaken he offers it on XDA as free download. Try to see what is causing partial wakelocks and kernel wakelocks (your phone should be on deep sleep mode for the majority of time). Try to see what MHz is your processor running at (it shouldnt be in the 1400 range for too long unless you are playing some heavy duty games)
Also try to search for threads on 'wakelocks' on XDA to get more details on this subject.
I have experienced close to 10% drop in 1.5 hr in stock ROMs and around 15% in five hours on CleanNote ROM in idle states with lots of background apps disabled.
Whilst I have been having the screen on, it shouldn't be burning this fast and it certainly didn't use to. 23 minutes on battery and 20% burned?
Did you install a new rom or new kernel? You can install an app like BetterBatteryStats to check out what might be causing this battery drain.

Stock ROM 4.0.4 and have never rooted or flashed anything on before. It is completely stock and unaltered in every way. All I've done is install apps. It just seems to have been a little bad recently. I have BetterBatteryStats on, but the it isn't wakelocks. As I said, I've got the screen on consistently so the phone will always be awake. It is just that 20% in that amount of time seems really high, even for constant use, and I swear it didn't use to be that bad. I've installed Juice Defender because it tends to be good in how it managers network and WiFi. So far, things seem to be stabilising. But, I still want to know what can cause such sharp drainage...
Do you have a lot of apps running in the background? This is most likely the cause. Brightness is a big issue also. Flash a kernal!

Check that you have Auto-brightness enabled. Also, I found that certain apps can drain battery big time. I agree with checking via a battery stats program. Maybe an APP is running in the background causing the cpu to stay at max speed?

Totally agree. Before I root my Note to delete some unuse apps from stock 4.0.4, the battery drains very fast. The most reason is some apps running in the background.
Did you change your sim recently? Sometimes the culprit is sim card.

Not fixes, but suggestions:
- An app like Green Power will stop data usage when screen off
- As others said, look into your display. My favourite app is Display Brightness as it adds an invisible slider on your screen
- For some reason, Chrome in the last week began to EAT my phone. I uninstalled it and I'm back to a blessed 1% an hour drain

Thanks for your link, really helpful for me:good:
You may have to check your battery. Will it be hot when you are using it? Look at your battery, does it look "fat"? It happened once to me before, after changing a new battery. It's fine now. It was caused by overcharging it during the night.
I experienced it on my previous phone, now im going to prove it again in my note because i changed my sim recently and now i cannot achieved the 5 hrs i had before that my original sim card, best phone can do now is 3.5 hrs. I try to contact my provider if they can restore my previous sim card and see what will happen, its just a suspect.

how can it be over charging. Doesnt it has built in function that cut-off power when charging complete. all modern chargers have that..
really would like to know cause i always charge the phone before going to sleep..

u r right..all modern chargers hv that..so, it will cut off the power when charging is complete..even I do put my Note for charging & go to sleep
So, dont worry..put your charger for charging & u can confidently go to sleep :good:
If you have network location checked and or GPS in /setting/location and security.
that's your suck battery problem.
Network location awake the phone constantly in accord with weather widget and lot apps in background that use this feature.

Help! My screen randomly lights up partial on its own, when I mean partially I mean the screen is off but the backlight is on and stays on until I press the power button. This happened before and I was told that LiteFlow was probably the cause of it, causing wakelocks, so I uninstalled it and I've not noticed it since. Then suddenly the last few days I've noticed it happen again, I've got betterbatterystats installed and I've been keeping an eye on the wakelocks, nothing stands out!
Is anyone else having this same issue?

This happens due to low battery mode. If it is enabled, once the battery reaches the % mentioned for it to deactivate, the brightness kicks in and keeps the phone on and not on standby.
Example : your battery is at 3% and the low battery mode is set at 5%. As soon as the battery charge hits the 5%. We face the issue.
