Hi!
from time to time i get the problem that my galaxy tab 10.1v has around 50% of battery left, and when i want to turn it on a couple of hours later the battery completely drained to 0% !!! i know there's a thread about that in this forum.
to get a hold on this problem, i'm looking for an app which tracks the battery level (e.g. in log-file, a graph...) and maybe even tracks battery usage of applications. the standard android battery usage display isn't detailed enough.
on my mobile, i've got the "current widget", which comes close to my demands. but unfortunately it doesn't seem to run on my honeycomb tablet.
does anyone know such an app which meets my demands? thanks

Hi all,
I love the Sony Tablet except its battery life. for something that is so huge compared to the others similar products out there, I am sure that they could have squeezed a bigger battery into the unit.
The power capacity is pretty weak. Let's hope that Sony offers a higher capacity battery size. I would gladly pay to upgrade it.
That's weird, my battery life is fantastic. If I play games on it all day it'll last 8-12 hours, but if I just use it intermittently and moderately it'll easily last me a couple of days. On standby it only uses a couple percent a day if that!
I'm the same as unclespoon. Even during heavy use, I get about 9 hours, which is way better than my old Galaxy Tab could ever muster. Standby usage is crazy low, its fantastic!
Not sure what you mean either about being larger than most other devices. The Tablet's 9.4" screen is smaller than almost any other full-size Tab out there (including the iPad) and since the back curves, theres not actually a lot of usable rear space (look at how thin its getting at the thin end, now imagine trying to fit a battery in there!)
I'm not sure you'll find a Tab out there currently with a better combo of size/battery life. The chunkier Toshiba Thrive will last longer, the thinner Galaxy Tab's will last even less, and my Tablet S always outlasts my iPad, so it might just be your device. Try checking Settings -> About -> Battery Use
I'm of the same opinion as the op. My tablet s has dreadful battery life and especially when it isn't doing anything. (50% usage is system standby) my old galaxy 7 was far far better (charged about once a week)
I believe this may just be because it is new (only have 1 full charge) as my galaxy s2 was initially unimpressive and then lasted 3 days of moderate use without charge. Hoping the same will happen to my s1.
Time will tell
My only guess was that you did a shoddy job of conditioning the battery. My old Galaxy Tab (the first 7" one) was hopeless, but when I replaced it, I conditioned the battery better and it was a bit better.
My Tablet S lasts for days and days and the standby usage is tiny. Check whats using your battery in the Battery Use screen and get back to us, we might be able to help..
I noticed advanced wifi lock was causing massive amounts of wakelocks (8 hours out of 10 according to the stats in settings/about).
betterbatterystats is not available via market but I am trying out the XDA APK now

I noticed that as well. If you have Advanced WiFi lock activated the tablet won't go into deep sleep mode, there of massive battery usage. I still have Advanced WiFi lock on my tablet, but only activate it when I need to download/update something that takes time. Otherwise I turn it off. It's not worth the battry drain.
Wow. Your battery life are fantastic. 9 hours? That's huge. I have not used my Sony Tablet till flat but given the rate of battery loss think maybe the most is about 5 hours which is similar to what many reviewers are saying.
Just can't imagine that those reviewers are so far out of the ball park compared to you guys. I am using juice defender Beta. Not to sure if its helping or not. But at least if I not using WiFi it shuts it off automatically.
My battery used to drain badly during standby. I found that the Friend Stream service was preventing the tab from sleeping. Killed the service a while ago and battery has been fantastic since. Pushed it to 3 days with light use. About 3 hrs of browsing and facebook. My battery level is at 68%, been off power for 20h40 mins, and used for about 4hrs today - facebooking, Internet browsing. Note that no specific conditioning was performed.
What are the settings that you have on your Tablet? Auto brightness, background sync turned off ?
how did you stop friendstream, and what the heck is it, did you just kill the process and it stayed dead? (sometimes as u know u kill process but it will come back).
Good question. What is the Android software revision now. My is Android 3.2.1 (revision 2)
I acutally just uninstalled the crap-app. nothing I use anyway. It is an app for facebook, twitter and other social networks. So just get rid of it. Uninstall and be happy
my bad. I confused the HTC name and Sony name.
Social Feed Reader was misbehaving. Once started it kept running... rather than dropping off to sleep (and into Cached Apps).
Something wasn't right so I force stopped it and it stayed dead.
An additional note - the Setup, Applications, Running Applications feature isn't 100%. Some background apps aren't displaying as running or Cached. Go figure.
So any special method to stop the social feed reader?
I'm getting those kinds of numbers on mostly auto brightness (and sometimes lower, at night), with background sync turned on, WiFi sleep policy set to default, and no battery monitoring or saving apps running. The only thing I did was single initial conditioning cycle and since then its been great.
Also note that software-decoded video files will take a lot more of your battery than the equivalent properly encoded file. I havent had any trouble with Social Feed Reader, but I never even set it up and judging by the many stories around here, I would uninstall it if you're worried about battery..

Hi, that's good to know. Thanks for sharing. Unfortunately think I screwed up the initial conditioning. so I guess I will have to live with the 5 hour battery of my Tablet.
Btw how do you do battery conditioning?

In Setup, Applications, Running Services have a look at the awake time (listed on the right side) of the running processes. You'll note that system processes (the ones with the Android icon) have been awake since last boot.... but you might finds others that are as well. I noted Social Feed Reader showing high awake time and decided to nuke it. Simply click the offending app. You'll be given the option to stop the app... which is what I did. It's an app so doesn't restart once killed. Hope that helps...
Final thought: at the top right of the screen there's a 'Show cached processes' option.
The could be an offending app in there. Kill any installed app you suspect might be a problem and see if that helps.
my battery life is excellent.
Sent from my GT-I9100 using xda premium
Im looking for an app that will do the following:
log the battery percentage at set intervals.
(for instace, every 10 mins it would take note of the percentage of battery left.)
Im having problems with the battery in my epic 4g and I think that an app like this would help me diagnose the problem.
The default battery monitor app kind of does this, however it doesnt record the actual times (to my knowlege) it just shows a line graph.
The battery is draining at about 15% over the course of an hour.
UPDATE: A big thanks to user: JR67 for suggesting "Battery Monitor Widget" This does exactly what I was looking for.
EDIT/UPDATE:
So, im making some progress trying to find out whats wrong. I put my phone on airplane mode for over an hour and when I checked it again the battery had not dropped a single percent, as opposed to non-airplane mode, which was taking about 10-15% in that same time period. I suspect that there is an app or two that are contancting a server a little too often. Im going to keep an eye on my data use to find out what could be using it. I dont think that I have any third-party apps that could be doing this so I think it is something default in CM9. I'm going to keep updating this with more info as I figure it out. When I get to the bottom of this I might start a new info thread with the details of whats going on (in the EVO 4G forum)
Take a look at Battery Monitor Widget. It will log battery stats at set intervals. You could also take a look at Battery Monitor. It keeps track of how long your battery remained at a certain percent.
Cool I just flashed cm9 and it seems to help a bit, I'll try the widget and see what up. The sprint store said the battery was fine. I also underclocked the cpu to .8 and that seems to help. Im also thinking it might not be sleeping properly.
If you think that your phone might be having sleep issues then you should use BetterBatteryStats.

I would use Battery Monitor Widget as a diagnostic tool and would only enable the monitoring/logging when I'm having battery issues. It'll cause wakelocks when it reads the battery stats.
I think I have the problem 'solved'. As soon as I turn off all mobile(3G) data the battery is fine. loosing 1-3% per hr. I wonder why the data is taking so much...
Hi
I searched the web and also on Xda but I could not find an answer to the problem I got. I want to know if anybody has the same problem as I have. Firstly I want to clarify that I am NOT talking about a normal battery drainage caused by background apps, foreground apps, enabled wifi, bluetooth, google background activities, synchronisation, facebook, google location settings, any antivirus app or something of that kind. There are plenty of threads about that and google search is full of this topic. I am talking about something else when it comes to sudden and quick battery drainage.
It already happened to me a couple of times when I use the built in projector of my phone (samsung galaxy beam). So I watch a movie on the projector and it takes let say.. around 30 percent of my battery life. After I turn the projector off, close all foreground and background activities I wait like a minute or 2 and the battery status drops from lets say 28 to 20. This is normal as the battery status somehow needs some time to get "updated". So after every single fore- and background activity is closed and I got 20% battery left I go to bed. Then in the morning I look at my phone and its dead meaning the battery dropped to 0 causing the phone to turn off. And thats not normal for me. (I do hear the sound of very low battery in the early morning meaning it doesnt turn off within 1 hour which would mean faulty battery) First I was thinking that this problem might be caused by previously overheating the battery but I checked the temperature and here all is fine. Also both batteries are not too old and still work normally (beside the described problem). I may add that using the projector itself is not an "extreme" usage of the battery. When I use the projector, play an HD android game connected to my ps3 controller ...that is a different story.
So my question is what could cause this rapid battery percentage drop even tho the phone has no activity at all and sleeps. Sometimes it happens and sometimes it does not tho..If I would not use the projector then I loose around 2-3 percent overnight, if I use it then I sometimes loose 20% without doing anything. And thats not normal. I understand that a lot of people dont have my phone, but I still would like to know if anybody had the same issue on his phone after "heavy" usage? Maybe android somehow thinks that there is still activity even tho there isn´t. Like a virtual activity making the battery think its in use and therefore draining it. Any thoughts on that?
Im running on 4.1.2 JB stock rooted

I wrote that already in the post. Its the Samsung Galaxy Beam.
ya, even my xperia m with JB 4.3 drains heavily.
This is a case where actual current measurements will narrow things down.
It could be that when you turn off the projector, there is still some hardware drain going on.
It could also be that the last "20%" of your battery is really only 1%.
For current measurement, see: http://forum.xda-developers.com/showthread.php?t=2487055
this can be due to some defect with ur battery or with the charger that you are using, you can rule this out may be by trying different charger and also changing the battery to rule out the battery defect. what @Renate NST say could also be the issue.
Problem solved
Ok. Just a little heads up. I managed to solve the problem. Thanks for the replies. This is how I solved it:
1. I first ran this app ( Battery Life Repair) to check for any faults in the battery itself https://play.google.com/store/apps/details?id=com.BoshBashStudios.batterydoctorrepair
2. Then I installed this app (BatteryCalibration): https://play.google.com/store/apps/details?id=com.nema.batterycalibration and followed the advise as written on the app (regarding full charge and discharge- I discharged it until the phone switched off). Find the XDA thread of this app here: http://forum.xda-developers.com/showthread.php?t=1024867
3. After I watched a movie on the phones projector I restarted the phone and it stopped from draining the battery until 0 and went back to a normal discharging state
So with a bit of heavier battery usage (watching a movie on the projector) the phone or battery somehow memorized this usage, and thought it has to continue in this state even after I ended the movie and turned the projector off. But the above 3 actions solved my problem. Its important to mention that you will still loose some battery life as you need to restart the phone. But this is obviously way better than having the battery run down to 0% for a virtual usage... :good:
PS: If you still got problems with ur battery you might want to replace it or change your charger...
I have a Samsung Galaxy Tab S 10.5" Android Tablet that I purchased around mid December of 2014. Not too long ago, I noticed that the battery life is significantly shorter. I cannot pinpoint when this started, because I wasn't specifically watching for any reduction.
Also, I did do the upgrade to Android 5.0 Lollipop, and then a minor upgrade to 5.0.2 about a week or two ago. When I go into the Battery section of the OS section, I noticed that, by far, the screen was using the most power, and the percentage was INCREASING. At about 8:00 in, the morning, the screen was using 20% of the power. But, at about 1:00pm, it was up to 36%--WITHOUT ANY CHANGE IN USAGE. As a matter of fact, the tablet was often sitting idle (with the screen locking periodically).
Another thing I noticed while in the Battery section of the OS section was that the full 100% of power consumption is not accounted for--I added up the percentage numbers of everything that was listed as consuming power, and they did not even add up to 50% of total power consumption, So what accounts for the rest of the power consumption?
This happend to me as well with my Tab S 8.1", and the problem causing it was All Cast, even when i didn't use it were running in the backround and used a lot lf battery. When i forces closed it the problem disapeard and i don't have an problem anymore. Mighr not fix your device, as i don't know if you are using All Cast. But, good luck.
Hello.. Can someone who knows about battery draining give some help? I ve got this phone a week or so and I think the battery drains kinda fast. I'm not sure. I used to have Xiaomi Note 9s with a super battery. I m uploading a few screenshots . Is it drains fast?? Or all looks normal? Thanks in advance
That is normal battery life for this phone. In fact it looks pretty good.
Thanks for your reply
On my phone there is always Android System consuming a lot of battery, almost like Screen. I don't know if that's normal. On a REDMI 9 of a friend Android System is almost consuming nothing
@Primal.pr28 the cpu behaviour is setup to react to user action, rather than anticipate user action. If reacting to user actions is priority, then you want to react to the user action as quickly as possible (phone = smooth). This is not efficient. It means that even the smallest actions may require processing speeds greater than necessary. With better optimization you could get at least 25% more usage of your device at no cost of performance. Consider switching battery saver mode on by default forever as well, don't think you lose much performance.
Yesterday I used phone literally from 100-0%, and I noticed strange thing, the reading that it reported as consumed power by the screen was ~48% but it says something like 1300mAh. So obviously totally incorrect. If the battery is 4250mAh, then half of it should be around 2100mAh, not 1300.

It's not percent of the battery capacity that is displayed. It's percent of all things like hardware & software usage put together including system and apps.

Do you use your phone for more than 24h?? Xiaomi is showing only last 24h battery stats.
I'm having the same problem, 12.5.5.0, I heard 12.0.8.0 is more battery friendly?
Same here, insanely bad battery life with 12.5.5, dont understand why, android system is using more than 25%.
Look at this horor, pls

18% overnight !
12.5.5 is same as 12.5.3, most resources are consumed by screen, sometimes buggy Google app "Carrier services". Around 10% overnight battery consumption, phone lasts about 45-50 hours (light use, web browsing, work profile, emails, Whatsapp, constant synchronization of private and work apps on).
