Battery with System Panel

I went to sleep around 11:30 last night. Before I went to bed I turned off mobile completely and had 94%. When I woke up at 7:45 I had 64%. Take a look at these screenshots and tell me how I can improve my battery. As you can see in the second screenshot I didn't use my phone at all but look at the drastic decrease.

That's odd for sure. Did you check the system's battery stats? Just seems like the app you're using isn't telling the whole story.
BTW, what app is that?

Anyone know what I could do to fix this?

First thing I'd target is system panel itself...an app that polls your phone for system statistics...yeah...

Was this a one time thing, or does it happen every night? Did you check the system's battery info, as suggested above? Are you running a custom kernel/ROM? Did you see CPU spikes in System Panel during that period? Was wifi on?
I frankly have no idea what your problem could be, but a little more info might help.

system panel is superb, it uses barely any cpu at all.
anyway to the OP, i do the same test every night, i leave my phone idle, then check system panel in the morning. i drop 6% in 7 hours, but yours definitely dropped a lot. obviously no app or process is showing up, so i would just reboot and try another test tonight. perhaps some glitch happened, radio was wacky, i dont know. but that's not normal.
however we do know that the stock ROM has a high current draw at idle, around 34mA, when other phones get 4mA during idle. so who knows maybe it's normal.
i wish i had some screen shots of my system panel figures to show you.

I've noticed abnormal battery usage with low phone signal as well. Think the phones (Inc and Thunderbolt) ramp up voltage trying to amplify a low signal.
But i notice that you have a graph for 8 hours but the usage report is showing you only 2 mins. Dont think it's giving you an accurate usage report while charging. Depending on what you having it charging on it's possible to drain more charge than your receiving. Especially with USB computer charging.

Linux is actually keeping the statistics, the app just scans /proc and other directories at intervals to log it over time. Intervals are 15 minutes-ish on battery, our target spec is <1 min of CPU consumption per day to perform this service. (Am the author)
Unfortunately SystemPanel also isn't finding the specific culprit in this case, i.e., it's only showing that app CPU usage isn't the problem. Best guess in such scenarios is either some app that is running in the background preventing the phone from going into its best low power state or is using a bunch of power running one of the radios. I'd next try doing the same thing in airplane mode.
Will be adding more data logging for additional such as network bandwidth in future versions.

What the usage report is saying is that in those 8 hours his System Processes only used the CPU for about 2 minutes. That would lead me to believe that there is something running in the back ground that System Monitor is not picking up. I would suggest doing what the Dev above me said and see if that might help figure out what process that is.

i believe system panel uses linux commands such as "top" which picks up everything that hits the CPU. so the offending battery drainer is something else, such as the radio for example going wacky, etc. i admit the OP's usage seems strange as i do the same test every night with system panel, but when something weird does happen, the ofending app clearly shows up in system panel.
the next step is taking logs with the current widget and seeing how high idle current draw is. i get around 5mA to 10mA idle current draw.

[HELP] Battery Use App has gone mad!?!

Hi folks!
I tried to search the topic before starting a new thread but I couldn't find any.
So, here's my problem. I noticed that since I flashed the stock JQ1 Gingerbread from chainfire's thread apart from everything else being fantastic, the battery use statistics in Settings -> Status -> Battery Use I can see are stranger and stranger.
First I have noticed that my the battery usage of Display had frozen to 2%. It is completely impossible, comparing it to the Froyo before, where it often went beyond 50 or even 60% of total battery usage.
Then, I saw that the Android System was taking about 90% of the stats. At first I thought it may be the infamous Gingerbread battery drain. It is not that, however, because I do not feel the battery draining any faster than before.
Then came the realization that no matter what application I am running, it does not get reflected in the Battery Use - only Android System percentage grows bigger. The funny part is that from time to time the total of all percentage goes beyond 100%
And, finally, today I unchecked the background update of the PULSE application, because I do not really use it and checking the Battery Use again what did I see. See attachment:

}
Not only the display category had gone away totally, but half of the battery usage is now transferred to PULSE, which I don't use.
Please, do you have any ideas how to repair that?
I am on a European Galaxy Tab, JQ1 2.3.3 Android + CF-Root v3.3 for JQ1

Not anyone experiencing the same problem? Just a little update from me. I read half the cloud already, strange but it is the first time that I cannot really find my topic in Google.
I tried what not - no result. I wiped battery stats, which only helped to the extent that the PULSE has gone from battery use stats, and display is back but the readings are stuck at 2% no matter how much I am actually using the display.
I read somewhere that it could be the kernel, where some thing may have not been allowed or switched on??? But if that was the case I would not be the only one with the same problem, but all the people that have flashed the ROM + CF Root 3.3 from chainfire's thread????
Still no ideas?

Hey guy,
Once ago I had the same problem. I don't think that pulse realy eats your battery. But we all know that the battery statistics is incorrect. So don't worry. Do use "AntTek App Manager ☆ root" (its free) to remove the puls app and wipe the cach. Or just install the overcome rom. It's much better then the Sock Rom. Trust me Because after removing of puls, there are other false statuses. I don't remember but i think it will show you that the battery is eaten by the core apps for more then 70%.
Sorry guy... I know about my terrible english

Hey odysseus84,
don't worry about your English. I am glad that you tried to be helpful. It is not that bad. After all I understood what you mean. You are right, even without Pulse in battery stats, I am still missing statistics for practically everything.
It is interesting that the Battery Use fails to record third party apps. As you can see below, the usage for all main system processes like Idle, Standby, Bluetooth, Wi-fi, Voice Calls are there. The statistics for display usage is stuck at 2% as already mentioned, which is the most annoying part.
Another interesting thing is that everything seems to be put into Android System usage, because normally it wouldn't get more than 10% of the overall battery usage share.
May I ask for other people running Gingerbread 2.3.3 to post their battery stats here?

Look. It's just a Bug. There is "Android System"written but it means the % of the Display. There is "Display" written but it means something else. As you can see on the attached pic we have almost the same "Display" usage.
And the other thing is that the statistics nothing shows with less then 2% usage.
Finally you can just accept it or flash something else.

Z3 D6603 - Battery life is not good

Hello,
So recently i've noticed the Battery performance on my Sony Xperia Z3 has become poor, I mainly use my device for socialising etc, I don't game alot. I'm currently Running Android 4.4 Kitkat (UK)
(I'm usually at home and connected to Wi-Fi)
See the results for yourself:

Check if the device is constantly awake at the detailed battery information if you click on the graph.
If that's the case, search xda for "wakelock" and how to get rid of it.
An easier attempt is, to think if it's a certain app you installed recently or a change you made to your system.

Thank you for your response,
I'll Go ahead and download a Wakelock Detector By someone who works here at XDA, and i'll see if it finds anything; But as of now my battery died again; So i left it dead for 15 minutes, and now i'm charging it back to 100% with no interruptions

You could also install the ota update for lollipop and see if that automatically solves your issue. (new versions are being created to be better)
Another option is to flash the lollipop stock rom and try if that solves it. (but that's a bit more advance)

I suddenly got a similar issue - not as bad as yours but a drop in battery life. I turned off scanning even when wifi is off and turned on location based wifi and my battery life went back to normal. I'd just had a Google Play Services update and have had this issue with various play services updates in the past on other devices which is why that was one of the first solutions I tried.
Might be worth a shot if you haven't already tried it :good:

There's always Greenify.

Repair it or flash another ftf file.

Same thing here. Since I've had this when I purchased it new I've not had any good battery life. My old z2 had way better battery life and stamina mode works.

Was there any update to this matter, OP?
What brightness options are you using? (% and adaptive or not?)
Also, did you actually update it to Lollipop? Was there any problem with wakelock?
Best regards.

Network & Wake Lock
The last screenshot you posted clearly shows that the battery drain is because of your Mobile Network and a Wake Lock.
Network Signal:
As signal strength decreases, the device requires additional power resulting in battery drain.
The cost of 1 hour’s worth of calls is 150mA, assuming a strong signal
So, on a 2000mA battery, it takes 8% of total capacity (8% =150 / 2000)
This means the same 1 hour of calls could cost as much as 23% of battery life (23% = 450 / 2000)
Wake Lock:
WakeLocks are a Power Manager system Service feature, available to your applications to control the power state of the host device.
Wake Locks can be used to keep the CPU running, prevent the screen from dimming, prevent the screen from turning off, and prevent the keyboard backlight from turning off.

How to fix terrible battery life after update?

I used search and looked through several pages of Q&A threads and didn't see an answer to this. If I missed the thread, please point me to it and accept my apology.
I updated to check for the recall and I'll be getting a new Shield Tablet eventually but my battery life nosedived immediately after the update. I read that Lollypop has had battery issues but the only fix I seem to read about elsewhere is flashing CM which does not interest me particularly. My battery life instantly dropped from 4-6 hours to barely 2 since the update.
When I went to battery stats prior to the update, I saw all the apps that were running and after the update I only see things like "screen," "android os," "android system," and "chrome." I'll have lost 50% of the battery and battery stats will tell me that the screen has used 15%, os & system have used 5% but there aren't enough percentages to add up to either the 50% lost or 100% of used battery life. I'm not even sure how to read the stats anymore.
Is there a kernel I can flash or something to regain the battery life I had prior to the update?
Any assistance is most appreciated.

Hi
I've actually noticed the same thing, thought I had lost my mind or something. Luckily I'm getting a RMA ( faulty battery recall)
But I would really like to find a solution to this in the mean time...
Tried a factory reset?

Its all about using hardware ....

Okay so In your tablet you got 4 core
4 core means twice as much battery use because you can adjust it y dividing them to half
which is with update they made the cpus using full capacity all 4 of them
so when your not gaming or with your gaming which is it didnt show any difference to me while Im playing heartstone
settings >shield power control>my power mode enable again and customize my power mode >max cpu cores 2
then try with this and youll be allright also
another poing I would love to make and share my experience with you
So far if any of your google apps or location apps is on they draw approx 30 percent more battery
Its disgracefull I know so for that
Settings>location>off
then another thing is I come across a lot
settings > wifi >advanced options ( top of right corner 3 dots)>Scanning always available is off
:fingers-crossed:

Limiting the number of active cups is not the option. But three are other settings related to CPU which not te reduce their number but reducing their frequency first. Your room possibly is too much conservative about power usage because Android is made to used the "on demand" governor for CPU settings and assumes that there's a scheduler that will update the frequency every few seconds instead of every minute where all cups will email active for at least some time, so that it is never really idle. The exists some tools like CPU tuner that allows defining the CPU parameters and the threshold of time usage for which the usage rates can be updated down or up.

Has anyone noticed that under the shield power control --> apps , one can no longer set apps to "let Nvidia optimise it" . Only two option available, disabled or custom
Running the latest update
Anyone else?

Something is messing my battery up.

While using Twitter or any app, my battery goes down at least 4-5%. I can't get decent battery on this.
I have the Verizon edition.

After charging the phone i think in all editions you need to reboot in order to stop the battery drain try it and tell us. It is like a "bug " on current firmware

The bug i told you is from android system battery drain
twitter and also facebook are battery non friendly....
i personally deactivate facebook and twitter with package disabler pro when i dont use them.
post your android systems battery stats
you had 25 mine is between 15-18
is your phone band new ? if yes maybe you need to let the battery make some charging circles

It is pretty new. I didn't think that would effect anything. I guess I will let it have some cycles then.

I have some ideas that might be able to get the problem solved. I would first try turning off your phone for 5-10 minutes since it might be overheating. Then I would uninstall any new apps that you might have installed since you can remember the battery drain starting. There is a small chance you might be experiencing some battery drain issues from a third party app that caused a virus. Its also a good idea to get a security app like avg since its free. Other then that you might also want to check that your phone is not completely full on storage, and also consider turning off the facebook app since it can cause some serious battery drain issues as well. I think thats pretty much it if you want to get rid of facebook on your galaxy s7 here is how to do it. and it will really help with your battery life

I had the same kind of battery drain on my Sprint variant. A factory reset quickly fixed that issue for me.

So I used it up for a day and let it die completely. Charged it right back up and now its pretty bad today. These are screenshots from when I made it die.
I did disable Facebook. The Android System and Screen are using the most up right now. It went down about 7% for being almost idle. I used Twitter once.

Possible Solution to the DRAIN!
Ok, so I've had the same issues as you. My findings are as per Gsam Battery Monitor:
1. High Android OS and Android System usage~ 20-30%
2. High Phone Radio ~ 40% at times
3. Overnight drain of at least 4% (stanbby drain)
4. Screen usage 'while off' higher than 'while on'
This was frustrating and is as mentioned by other users to be a bug from updates and related to charging.
SOLUTION:
Today Gsam reports my Android OS and Android System usage and Phone Radio at 10% and below.
All i did was...
1. Let it drain to about 90% after charge.
2. Restart the phone.
3. Then plug in the micro USB to USB connector (the one that comes with the phone) with a flash drive attached and play a song/short video.
4. Unplug and enjoy great battery life.
This worked for me so it's worth a try. Will test a full charge soon and hopefully it doesn't require the steps above every time to stop the drain.
btw I'm NOT rooted, using LTE.........wifi,bluetooth, AOD and locations all off.
