Here is a puzzle. Overall problem statement is that when the battery level is below 40%, the battery drains quickly with minimum wakelocks. In other words, the phone does not "deep sleep" when battery percentage is below 40%.
My definition of "deep sleep" is battery drain slows to less than 1%/hr and this is usually shown in the battery graph as a near horizontal line.
Phone: Samsung i337m (Telus)
ROM: Kitkat 4.4.2 NE1 Odin flash firmware, so everything is NE1.
Other info: Towelrooted, Xposed Framework installed
Below is a screenshot dump of the battery info, BBS, and Wakelock Detector (WLD).
Observe that BBS and WLD are logging since last unplugged at ~1.5 hrs ago. So when you look at the battery info screenshot, please take into account the last 1.5 hr time on the right hand side only. If you look carefully, there isn't too many wakelocks. This is confirmed by BBS and WLD.
Only exception is in the last SS in WLD showing NILS program keeping the screen on for 8 min & 32 sec, which doesn't really make sense.
Check out the last SS for the Poor Battery Drain batch to show that battery drain is much higher at 1.2%/hr over a 7 hour period. This is compared to 0.7%/hr over a similar 7 hour period. The only difference is the starting battery level.
Good Battery Drain SS posted for comparison purposes and to illustrate my point
Based on the above, my only theory is that the battery calibration is off such that below 40% the battery has drained much more than indicated....
Any other ideas or suggestions to fix this problem?
Poor Battery Drain
Good Battery Drain
hey guys I'm asking if it's only me or I'm having a bad battery life?
I have phoenix v10 installed and googy kernel with battery profile.
When I dont use it and the screen is off the battery last very long but if i start to use it a bit the battery start to drain pretty fast. I also noticed in battery menu that android os and android operative system is draining me 17 and 12 % for a total of 29%..
is this normal?
I will post a screenshot tomorrow of my battery life and a screen of BBS wakelocks.
Fast charging the battery? Bad data cable? Bad battery? Could be anything
"If someone helps, never forget to hit thanks ?"
the battery its good. the cable too. the battery charge it's the default i guess

Yes it's normal.
Your screen uses power. Also 29% is relative of the battery consumed. So If your battery is still at 99%, then android os etc can still have used 29% of that 1%.
I changed from Note 3 to s 6 edge plus recently
The battery drops 5% per hour overnight when not in use. If I go to bed with less than 40% battery at night I am sure to wake up with my phone switched off in the morning.
When in use with screen on, the battery drips one percent every two minutes. This is the worst battery life I have ever seen in a phone. I was a long loyal customer of samsung and this is my last samsung phone ever.
Extremely disappointed
Please post your battery stats ? so we can have a better understanding of your problem. I suggest you install 'Doze' which should stop unnecessary apps from connecting to the internet and causing your phone to awake from deep sleep.
Dear Akbar 11
Heres the battery stats....is it normal?
I had the same issue, and as far as I managed to find out, it is a bug in Samsung's kernel. Flashing Arter97 kernel solved the issue for, but do post battery stats from SmartManager. If it says 'Android' or 'Android OS', then you have the same problem many of us do.
I don't think it's a kernel problem. My android OS is very low 4%. Like zoolok said post your battery stats from settings, battery, battery usage
I have the same problem. Battery was great before I flash custom rom. After going back to stock I have big battery draining. I must stay on custom rom. With Audax rom and Skyhigh kernel i have great battery life.
You have either messed up something big or you have an app in the background that is eating up your battery like no tomorrow.
And the reason i say that is because i recently got this battery life on my Galaxy S6 edge+.
And this was taken 2 days ago.
Here i use the CRISSCROSS ROM, AudaxPro Kernel, Greeinify and Samsung's own 'Appoptimizing' feature (same as Doze in Android 6.0).
So my battery life is pretty awesome.
i have problem whit battery lose 25% when i sleep
This is a usual day with s6 edge plus
Any help?

i have this problem battery ... if u fixed it tell me how?
Well I was expecting Google Play Services to be eating your battery (which is quite common) but it looks like your Andriod OS is eating the most battery. I would uninstall Facebook and use the web version it always helps with the ram and battery furthermore, turn off location if you are not using it and check accounts which are being synced. These are the only tips I can give you as I have never seen Android OS drain so much battery.
Since a few days Google Play Store is eating up my battery: I go to sleep with 100% batt and wake up with 50%, if I check batt stats on top I have play store at 45%, with 5h active a d 2h of CPU.
Follows Android system at 5%.
Going crazy why...

You've charged your phone 4 times during that day. I can't see what's the interesting part here.

Most Likely Yes, But Your Usage Is The Largest Factor Discerning Whether a Battery Is Healthy. Install Betterbatterystats And GSAM Battery Monitor To Find Out What is draining your battery and which wakelocks are preventing deep sleep. Check your usage if it seems normal. Then the battery is the problem
