I have seen many posts about the poor battery life on the ADAM when in heavy/normal use. I have seen very bad battery drain just in standby/sleep on all the roms I have tested (Stock Newest build, edenx, and now CM7). SetCpu currently doesn't support profiles but I wonder if the processor still runs heavily even when in standby.
I should note that i usually turn off WIFI when not in use and also background data sync.
Pixel Qi Wifi.
As usual, after unplugging the device in the morning and not touching it for 8+ hours, it has about 50% battery left and battery history shows Phone Standby using all the battery. I guess these quirks will not be resolved until Honeycomb if ever.
Which do you mean "cell standby" or "phone idle"? I have the same model and the battery still drains more than expect overnight, but notas much as 50%. Did you apply a fix to remove cell standby?
Phone idle is what is reported. Here is a more specific example: on battery power for 10 hours today in standby with wifi off and background sync off and the battey is down to 55%. This is not a huge problem but I dont like to leave it on the charger constantly when not in use.
Kill the "phone Idle" <- that's really draining and if you don't use SIP on a WiFi only you can de-install phone and phoneprovider
2 other things you could try,
Install from the market:
"autokiller memory optimizer" and
"Juice defender"
They seem to help for me.
or use BEAST ROM 2.2. My ADAM batterie status is after 23 hours on 36%.
Hi Guys,
I am wondering is there any of you having same issue as me ?
I am using TILAPIA device and suffering from around 5% / H battery drain during idle (all off and in airplane mode)
strangely, BBS report is showing my device is in sleep mode for more than 90% of the time
as per now what I can think of is to set tasker profile to shut down the device when screen is off for 5 mins
but I am still curious why and what is the cause of battery drain while the device is actually in "sleep mode"
Thank you

Hi, I have same problem. Asking if anyone can see something weird in BBS dump in post here
P.S. Concluded that my case is totally same as described here
I have a new Samsung S4. Trying to learn how best to configure it to minimise battery usage and to ensure I don't install apps that eat battery. There's nothing wrong with it, battery usage is fine, just trying to get the best out of it; whilst keeping as much functionality as possible without having to constantly turn things on and off. I'm trying to avoid rooting it.
As a starting point, I'm checking usage overnight, when blocking mode and power saving are on, with wi-fi and data off; but with the alarm clock set.
I have an i-onik 7.85" tablet on Android 4.2.2 - with a deep sleep battery saver app set to slumberer ("always deep sleep when screen off") it only uses about 2% of battery overnight - the battery currently holds about 3600 mAh - so that 3% equates to 108mAh.
First time I tested my Samsung S4 (the european LTE version 9505), (actually I think I had wifi, data, location setting turned on and power saving turned off), it used 4% battery overnight. Not bad, 4% of 2600 mAh is 104 mAh. Still I thought I might do better. I tried the deep sleep app on slumberer but inexplicably the usage then jumped to 12% (whereas it at least halves battery usage on my tablet). I've since un-installed deep sleep battery saver and started turning off wi-fi, data, and turning on power saving - so I'd expect it to use 4% or less battery overnight.
The actual battery usage instead increased to around 9% to 12% - although the settings used might have varied.
Three nights ago I made sure that all apps were closed, and everything turned off as above - battery usage overnight was still 9%. I used WakeLock Detector and found that a Morrisons App was causing wakelocks. I uninstalled that, and the next night the battery usages was down to 6% with much fewer wakelocks. Still not as good as before though.
I then found there were wakelocks due hotmail and gmail sync - hotmail I changed from push sync to sync every 4 hours, gmail I changed from hourly sync to manual sync and I also turned off master sync. I also turned off location setting. That cleared the wakelocks for these apps, but battery usage last night had increased to 9%.
So, despite the same settings and less wakelocks (and it was in deep sleep all night except for 16 minutes), battery usage increased from 6% to 9% - still no where near the 4% I had at the start despite making various changes that should reduce battery consumption.
The only significant wakelocks last night were:
com.domobile.applock (via alarmManager) awake 35s giving 992 cpu wakelocks
com.google.android.google (google app) 7 wakeups
Can anyone think of any cause for increased battery usage from 6% to 9% despite more time in deepsleep, less wakelocks (other than the 2 above but there were many more wakelocks the night before lasting several minutes) and location setting turned off. I wonder about starting again from a factory reset ... NB every night before going to bed I've rebooted the phone, and charged it to between 90% and 96% and it's been tested over the same period of time. Is it normal for battery usage when the phone is sleeping to vary so much?
Charging the battery inconsistently might lower the battery life. And letting it discharge to much does the same. I generally avoid letting it go under 50% and unplugging it before 100%.
I don't know what causes your issues, but if you want full control over your phone, you will have to root.
I also had 2% drain over night at some point, but now I have 4%. But this may also be rom related.
Thanks. I'm on stock ROM. I have rooted other devices but then find some apps don't work, and of course I want to maintain my warranty.
Each day my battery is generally dropping to about 30% at which point I charge it up to between 90% and 95% before turning turning most things off ready for bed.
At some point I may leave it plugged in overnight instead - is that a bad thing?
What do you mean by charging inconsistently? Sometimes my battery may be around 50% though more often around 30% when I start it charging.

By charging inconsistently I mean exactly what you said. You charge between 90 and 95% generally, instead of leaving it to charge 100%.
Somebody said that if you live in the EU you will not lose your consumer rights. I guess that includes the right to have your phone repaired because it is in warranty. Other people have reported that the phone service accepted and repaired their phone even though it had knox flag 0x1.
There isn't much you can do on stock unrooted roms in order to reduce battery consumption.
You battery drain is probably caused by weak signal strength. Having bad signal uses more battery. The screen and the phone radio use the most power on the phone. If you put our phone in airplane mode there should be almost no battery loss. If everything is turned off.
On my old device I used to put in airplane mode during the night. I had 0% drain over night in airplane mode.

Thanks - that's a good point about signal - my mobile signal and wi-fi signal does seem to vary, so that could contribute to fluctuating battery usage. I decided to test that by using airplane mode and have started charging to 100% on your advice. Unfortunately when trying to dismiss the prompt to upgrade to lollipop, I accidentally started the upgrade, with no way to cancel it. (For me, lollipop really seems a downgrade, I've lost a lot of functionality I used all the time in KitKat).
The bad news it that on lollipop overnight last night, despite using power saving mode and airplane mode, and basically everything else off including sync, it lost 7% of battery.
So I decided to do a factory reset, thinking it would go back to KitKat - but it didn't - it stayed on lollipop. It did give me the option to choose which extra apps to install (including some Samsung ones) - I declined to install any extra apps, and also turned off automatic app updates - I then turned off sync, backup and anything else that I thought might eat battery - leaving the phone with the most basic set up possible. I've not since installed any apps except Talk2Go.
The good news it that since the "factory reset" to lollipop, I've tested it for two periods of 4.5 hours on airplane mode, everything off, and I did not turn on power saving mode. The battery lost less than 1% - in fact for my last test it stayed at 100%. So either the reset fixed battery loss on lollipop, or the power saving mode was actually causing battery loss!
I'll investigate that and report back for the benefit of other users. I'll then gradually update my settings and see what, if anything causes battery usage to increase when on airplane mode. Of course it's also possible that battery usage might increase without changing anything, as per some reports from those upgraded to Lollipop - if so I'll report on that - and confirm if a reset seems fixes it.
Lollipop is supposed to have a battery saver mode - but it seems to be missing in the stock OTA update to S4 - does anyone know how to use this mode? It sounds better than Samsung's own power saving mode (especially since that might actually be causing battery drain rather than saving battery!)

Samsung probably replaced the stock lollipop battery saver with their own battery saver.
You could return to kitkat by flashing via Odin. Doing so will not give you knox status 0x1 and you don't even need root.
On second thought, you have the new bootloader so you probably won't be able to do it without tripping knox..
From what I saw, battery saver changes only the minimum screen brightness to a lower value than normal and it changes the CPU governor to a more battery friendly one.
This is what I observed on the GPE rom battery saver mode.
Testing continues - for the first few nights battery drain was less than 2% on airplane mode, but it wasn't repeated last night. It drained 9% with exactly the same settings (ie everything off except the alarm clock, no foreground processes running and airplane mode on).
I've installed a few apps - one from TalkTalk, one from Three Mobile, a terminal emulator and wakelocks detector. So have now uinstalled the first 2 to see if they are causing the drain - BUT I suspect it's a bug in this release of Android Lollipop.

Many people have problems with the stock lollipop. Samsung messed up.
It might also be the battery. I have my phone since november. My battery used to drain 2% over night. Now it drains 4% over night. Basically it drains very fast to 96%, from there it drains normaly, depending on the usage. This happens on every rom I tried and with even the most battery oriented settings.
You seem to be using applock. If you don't need it you can delete it and get rid of a few wakelocks.
Hey guys,
I am an owner of Meizu Pro 5, but I am experiencing heavy battery drains. Tried flashing an older Flyme version 4.5.x, 5.1.6 and 5.1.10 and on all of them the battery drain is heavy. "Cell standby" is taking almost 60% dont know why. What can be the problem from ? :/ Can I have the famous Mobile Radio Active bug ?
As always:
1. Install bettter battery stats and wakelock detector from googleplay
2. Turn off WIFI/BLUETOOTH/DATA and reboot phone before going to sleep and save log next day.
3. Next day enable WIFI before going to sleep and save log.
4. Then BLUETOOTH.
5. Then DATA.
:good:
Hey guys,
I know that there are too many people with battery drain problems in the forum. But I'm getting frustrated with the battery life of my S7E in the last few weeks. So I hope you can help me.
I'm using the latest Super Stock Rom V.2.4 on my Exynos S7E, connected to a Gear S3. Over the last few months I was able to get 5-6h SOT with any rom I used. But in the last few weeks I'm having strange battery drain. I'm having the battery issues with every rom I tried after a few days. With and without a connected gear
Issues I notized in the screenshots:
1.) Wifi was deactivated 80% of the day. But why is BBS showing me, that Wifi was running for the 100% of the time?
2.) The usage of the Proximity and Grip Sensor seems too high for me. What could cause this activity of both?
3.) 5000x RILJ wakelock? What the?
4. 1500x Android System Wakelock (things like Imsservice, *alarm*, motionservice and so on)
Some screenshots.
force doze disable sensor ?
