Sudden excessive battery drain starting today (11/30/12)

I noticed today that my phone connected to the computer's USB wasn't gaining any battery this morning. Unplugged I am losing about a percentage every few minutes, quite excessive. I recall that there was an update to AllShare today and looking into it "Media" is my top couplet in "Use details" using 55%+ battery. I am trying to track down the app or setting to fix this battery drain.
Going into Allshare Cast I can turn it off in settings, but when I go back in its right back on.
Under "Media" Included Packages are as follows:
Downloads
DRM Protected Content Storage
Downloads
com.sec.android.providers.downloads
Media Storage
Does anyone have any clues or suggestions to track down the offender?

I should also note that I do not have any "DRM Protected Media" on the device nor do I have any media players active.

I would look into uninstalling the update, it seems the beginning of your issue

I have tried uninstalling everything AllShare, force stopping the "Media" under the battery only to have it restart on its own.
I guess I will try reformatting my SD card.
It is quite warm around the reader.

I had the same problem and reformatted the sdcard fixed it

I got the allshare update this morning as well, and no issues so far.

Just do a cache clearing and see if that helps.

I had this same issue. It turned out to be a bad SD card. Reformatting didn't stop the battery drain.

I have been losing a % a min since I got my phone! I am stock everything. ..I can't tell what is the cause either. I came from an epic 4g and its battery has always sucked do I was just used to bad battery life but then I get on these boards and folks are talking about how great their Bay life is. ..I just chalked it up to my not being rooted! Since I am not interested in rooting at all, should I just plan to continue taking my charger everywhere I go? Any suggestions?

Honestly, I have everything on except bluetooth and roaming. I even have a live wallpaper. Go to settings, then battery. See which process is draining the battery. This is my second Note. The first one stopped charging after a week. It would light up the red led and charging icon. Only give away was no charging indication on lock screen and no increase on charge level.

Search XDA for an app called Better Battery Stats. Look for any app or programs that have excessive wake locks or kernel wake locks. Google is your friend.

I have been suffering from the same battery drain issue. Its's really annoying. I think I get about 8 to 10 hours with normal use. I normally text with the rare chrome usuage (since sprint 3g is slow) and I seem to lose a % every few minutes. It says my screen time on is the culprit and next under that would be android os. I can't seem to figure out whats wasting my batter.
Does a reformat really help? How does that affect the batter?

its probably your battery. i recent had my stock battery do the same thing. i turned it off at 90% one day and the phone would turn back on. stuck the battery in a charger and let it charge for about 10hrs. when i turned put it back in the phone it was only at 60%. for them on out it only last 8-12hrs max with minimal use. i ordered 2 anker batteries from amazon and curretly im going on 1day 7hrs and some change with 8% left.

It seems that my device idle is never any where near the top. I just checked, its at 2% for idle. So something is keeping my phone on in the background.

Battery percentage setting issues

Hi again,
Just about to give up on this tablet when I noticed that it seems to be the battery percentage setting that is causing my charging and discharging issues.
With the setting turned on and the percentage visible, the battery seems to discharge and charge oddly, and also the percentage shown does not reflect the amount shown on the battery icon, or at least it rarely does, but it varies.
With the percentage setting off, the discharge seems much slower and predictable.
If you have a p600, could you possibly try this for me with and without and see if it matches with my findings?
Thanks.

I'm having very odd battery issues myself. I'll give this a try and see if it improves for me.

With it on I have noticed............ If I remove charger at 96% next thing I notice battery is at 100% and my battery app charts that jump.
I'm using Battery HD, are you using a battery app also?

Thanks for the reply. I'm not using any battery app, just the one that comes with the stock tablet.
I think I did encounter the same thing as you, and also unplugging at 100%, then taking it upstairs and looking and it was 96% or so, and then after a restart, it was 100% again. Very odd, but it doesn't do it for me unless the percentage setting is enabled.

No i suspect my device might have some deeper issue. I can drain the battery from 100% to 0 in an hour of playing games but if i turn off the note and turn it back on, it'll be back at 60% or whatever it's actual battery level is. I can rinse and repeat and slowly get it down to 0. Either way the battery drains much quicker than it should. It could probably only last 6 hours of screen on time with very light usage. I might need to get motherboard or battery replaced.
I am still hoping that its a software glitch and something like this could fix it.

I wonder if the tablet needs a little time to calibrate the battery usage, maybe there is an internal process that has to happen over time?

I've had it since it was released in october or november and the battery life used to be good and last 10+ hours and probably 5-6 hours while playing games. Not sure what happened in between. It has taken a few very light drops with no visible damage and i did break (bend) a charge with it in the tablet but the charging port seems normal and still works fine.

Just checked with battery % off for 30 mins and battery dropped 4% which is normal.

I still had crazy battery drops with the percentage turned off. so didn't seem to make any difference for me.

Is your unit still rooted????? If so have you tried removing root and installing the most current factory rom.
Have you seen this post "Longer Battery Life (or How You're Being Robbed!)"
It may help some that are having issue with battery drainage but after seeing your post #36 in the BATTERY posting .... I'm leaning towards a cracked or damaged board from the few drops you talked about.

I've tried unrooting and odined back to a factory rom, also cleared my SD cards, nothing helped so i'm back to being rooted for now. I've done a lot of the tweaks to improve battery life but whenever I play games, it just drains like crazy even with minimum brightness. The drops were very very minor, like from 1 foot onto carpet and with a case so I doubt that it was the cause but I guess theres always a chance.
I'm still wondering if I should just live with terrible battery life and stay tethered to a charger or risk sending it back to samsung and having them find out it was rooted and overcharging me for repair. And I love the device so much, I don't know if I'd want to give it up for a week or two.

Tested again last night and this does seem to be the problem on my unit. Just over 2 hours and the battery icon had barely moved, and looking in the settings, it showed that I had 84% left. Hopefully it wasn't a one off.

Thanks :good:
So, I wonder which is correct, the icon or the percentage? If the percentage is right, my tablet is faulty. If the icon is right, it would seem to be ok.
And all these reviews and people that get 10-12 hours, I guess they went by the icon?

The percentage gives a more accurate time I guess.
But people and myself use the "Screen on time" as the usage data.

Was doing ok last night and then came here and the battery took a dive. Went and grabbed adblock for firefox and ghostery and ghostery was reporting 65 trackers on this site. Also the malware popups were becoming ridiculous and they only happened here. Going to do a factory reset and not come come here tonight, see if that helps anything.
I did do a bit of a search regarding the malware here, and it was being reported as early as last june it seems.

Battery Issues

Our devices use a 4600 mAh battery and was wondering if anyone ever actually sees that figure? I've been struggling to get more than 4-5 hours use and started investigating why. The highest I've ever seen on a full charge is 4309 and the average is about 4260-4280.
Another strange thing I've noticed is that if I start playing a game with 100% charge and the tab plugged in I still loose about 1% per minute.
I've tried multiple roms and they all seem about the same as far as battery usage goes. Right now I'm back to the stock LG KitKat as it seems to perform about the best for me and very stable. I use the battery calibration app and was wondering is there another that might work better?
In closing looking forward to any suggestions or advise

Yep,same for me.battery life is terrible.have tried multiple roms,lucky to get anywhere near 4hrs.

I just tried an experiment, 100% charged, unplugged tab w/o turning anything on and I already lost 7% in 15 minutes !! I have Greenify installed and all non system apps hibernated and it still eats the battery.
My Sero Pro can sit all day and only loose 1%. If I could be sure I would receive a perfect unit I would consider RMA. But after reading all the issues with the screen problems I'm not going to take the chance. My tab is perfect aside from battery life.
I found a replacement battery on Ebay and am considering buying it to see if I have a bad battery. Something definitely isn't right.

I went to Mahdi rom as soon as I got my tablet about 2 weeks ago. This past weekend I did two battery tests.
These tests were done with wifi always on (medium signal strength, most google apps synced, google location reporting off, no twitter/facebook app, no greenify or any power management apps
If I left the display on indoors at auto brightness, it lasted for about 7-8 hours.
If I left the tablet idle (display off), it consumed about 3% per day (most of it consumed by wifi).
I would suggest trying the same thing with yours and see whether its a hardware issue. You can just do it for a few hours and extrapolate.
I've never calibrated my battery (drain until its empty) unless I notice an erratic drain from a constant task.

Mine is the same, not being used it drains almost nothing. Currently mine is at 49%, been unplugged about 12 hours with 2:47 of screen on time according to the battery stats in settings. 100% stock KitKat, bluetooth off. 15 minutes of screen off (with the screen on long enough to look at battery settings) and no % lost.

Same. If I leave it in standby overnight, I see zero battery drain (in 8 hours). I also tested a full HD movie (1080p) in full screen at 45% brightness and medium loudspeaker volume, and measured roughly 12-14% drain per hour, which suggests it could run 7-8 hours of movie playback on a single charge.

I'm happy with my battery usage. I think it's at least as good as my 2012 N7.
Here's a screen shot of usage just reading the other day. Keep in mind I mainly stop my tablet charging at between 90-95% as often as possible.

I'm with the OP as far as battery drain goes. Mine loses almost 10% in 12 hours at idle with wifi on. With wifi off it'll lose about 3-4% in 12 hours. I haven't done a full to zero test, but battery life is not that great on my personal unit. That is the only thing I don't like about it. I'm running idterror's v50018a ROM.

Then you have an issue with software you installed. It is neither the battery nor the ROM.

Well I went ahead and ordered the battery. I'm fairly confident it'll solve my problem. To Subtleone, with my tablet even with a barebones install I still have real bad battery life. It does not change very much between barebones and all my apps installed.

I don't think so. Even with a barebones install I get similar battery drain. But I knew the G Pad had terrible battery life going in as noted by every industry review I read prior to purchase.

Don't have any battery problems here (stock KitKat, rooted and most non-system apps greenified), get about 6 hours screen-on time at 70-100% brightness when reading books (wifi off) and an hour or so browsing/youtube'ing.
Are people actually going by unplug time until the device physically shuts down, or just what the battery bar claims? Battery stats are rarely 100% accurate, and there's protection measures built in to prevent a battery actually reaching 100% or 0% despite what the device says.

Except that I don't have terrible battery life. In fact, most don't. With KitKat (the one in my sig), with WiFi on, I get exactly 0% drain after 8 hours with it in standby (not actually off). Zero. Needless to say, I do not have any known battery killers such as the Facebook app.
At 45% brightness or so, I see about 13% battery drain after an hour of watching a 1080p movie in full screen with sound coming through loudspeakers.

Biggest battery eaters are apps like Google+ and Facebook.
UCCW and Weather apps too. Also having gps on.
There's some smashing eye candy apps for use and just for info on your lockscreen, they all seem to suck juice like no tomorrow. It's all the updating they do.
Best advice is to use something like wakelock detector to highlight your problem apps, then use greenify to get them to sleep properly. Also have your wifi set to only stay on when your tablet is plugged in.

To test a lot of theory I loaded up stock LG KitKat this A.M. . After letting it install and rebooting 3 times in 60 minutes I turned off WIFI and GPS and left it idle. In 4 hours and 12 minutes I was at 79%. Keep in mind when I left it idle the last time I was at 100%.
So at least in "my" case its most certainly not the software. My battery is scheduled for delivery 5/9/14. I'm hoping that will solve the battery issues.
Once I receive the new battery I'll update the thread. And thanks for the replies

My GPS is always on so I do not think it drains battery in any unusual way. I'll also add that it works darn well. I used the tablet for navigation in a car and it was impressive.

So to continue the theories I put my screen @ 50% watched 60 minutes of 1080p video via MX Player and lost 31%! That's totally bare aside from MX Player. So after seeing Subtelone's results I'm very convinced I indeed have a bad battery.

I know it's not a fair comparison but I've been using my mum's Acer W4 tablet as my 8.3 is being repaired for bad LCD (mura/spots). The W8.1 tablet actually gives me about 8-9 hours of web browsing time. Yes, it's got fewer pixels to push but bear in mind it is running the full fat Windows 8! I just think it's quite disappointing that the LG pad for me barely lasts 4 hours SOT when I mainly use it for web browsing.

Yes, something is seriously wrong with your battery if everything else is identical. My results are exactly as posted.

another battery life issue

I'm sure this question has been asked before. But I'm coming from an iPhone so Neff help with this.
As soon as I start using the phone in the morning when it's connected to WiFi. Within a second of using it or 2 minutes if we're being realistic. The phone loses 2%. Is this normal ? Coming from an iPhone where 100% would last at least 20-30 mjnutes. I can't seem to find anything draining my phone either !

I think a longer observation period (a full day / through the night) will give a better idea of how your battery performs. Use the default power settings or other batter monitoring application like GSam Battery Monitor and compare it against other users here.

I'm sure this question has been asked before. But I'm coming from an iPhone so Neff help with this.
As soon as I start using the phone in the morning when it's connected to WiFi. Within a second of using it or 2 minutes if we're being realistic. The phone loses 2%. Is this normal ? Coming from an iPhone where 100% would last at least 20-30 mjnutes. I can't seem to find anything draining my phone either !

Had about 3-4 days worth this end will keep an update here. So far not bad been intense usage for about 2-3 hours lost about 25 percent. Could be worse

Well that's 3.5 hours of screen on time and you're at 45%. That doesn't look bad to me.

Any update?

Got nearly 20 hours off charge with moderate usage throughout the day with a mixture of WiFi and 4G. Turning power saver at 50. Phone had 33 per cent left by end of day.

Urban myths and old wives tales. Cycling the battery doesn't "improve" battery life on a Li ion battery. What you are possibly doing is making the battery meter more accurate (placement of the "high" and "low" flags that correlate voltage with "full" and "empty"). But its just a means of measurement, and this doesn't affect the battery life itself. Meaning, it doesn't "improve" battery life any more than messing with the fuel gauge in your car would increase or decrease the amount of gas in the tank.

This doesn't mean anything. The battery % is just an estimation based on battery voltage remaining versus how the phone "thinks" you are going to use it. Comparing 98% on Android versus 100% on iOS is apples to oranges. There is no standard for this, or reason to believe they are in anyway comparable.
As previously noted, 3.5 hours screen-on time with 55% drain (45% remaining) is very normal, even good. A lot of things affect battery life, not least of which is how you use your phone, and cell reception in your area. You will see a wide array of variance in the battery life people get. And since yours seems actually pretty good, I wouldn't worry about it.

Thanks [emoji3] it was actually &37 percent but that's still pretty good with the battery save g options available I should be able to exceed a full day in the event of an unplanned night out !

To be fair, I feel like Apple designs their phone where their first 20% will take forever to drop but as soon as it passed that point it falls to 0. And yes I've seen it shut down at 10, turned it back on it's at 2. Where as this phone's last 15% seems to take forever to drop.

id say thats pretty good life outta the battery. the more you use it the more its gonna drain. and those getting like 6 hours of screen on time are strictly on wifi at an office or something. if your out roaming with LTE and the such your probably not going to get 6 hours...

Intense usage on 4g with lots of camera usage and uploads music and a few phone calls. So far so good! Had more than enough when I got home to leave without changing I case I needed it

I feel the M8, and my past Android phones take a disproportionate amount of time to drop the first few % as well. Maybe not as much as what you are mentioning for the iPhone (couldn't personally comment). May have to do with the saturation charge that occurs when the battery nears full (in fact, you should actually leave your phone on charge for some time after it says full).
Also, the battery meter on any phone is far from accurate. It often can't really be trusted with be within 5 or even 10%. So that would explain why you saw it "jump" down 8%.

Yeah my point was that all these phones' measure battery differently and not exactly accurate so you shouldn't compare Apple to oranges. Oh and the jump in percentages was referring to the iPhones. If anything Android tends to jump up when turned back on lol.

Battery life

Hi, yestarday, I've recived LG g3, I've switched to it, because my G2 starting to have very poor battery life, like 10 hours with 3h with screen on. I've searched the forum, and I notice that most of u have 5, 6 hours screen with 30 h or more of use, but for me it will be the same as on g2, maaaaby a little bit better, I've restored all my apps, yes, but non of the battery monitor apps showing that some app is using high percentage of battery, let me show some screen shots:

Some of them can ba inaccurate, because I've just rebooted my phone, but u see that my phone was on 12 hours (with about 7, 8 hours at night doing nothing and switching to 2G only) I had 2h and 35m of screen, and I didn't play any games, just browsing internet, and I have 46 percent left...
What could causing this poor battery life? It can be some app, that is not showing in battery monitor as a draining one? Or what could be the issue?

You need to root your device and install Better Battery Stats, Xposed Framework, and Wakelock Terminator. Then use bbs to determine which Wakelocks you need to terminate to save battery.
Using this method got my battery drain down to about 1% per 6h of screen off time.
I had to terminate 2 wakelocks to fix my battery life: NlpCollectorWakeLock in Google Play Services, and WifiOffDelayIfNotUsed in Android System.

Nyorbee, I might be wrong, because I own g3 only for a few days, but your battery life looks to be pretty normal to me.
The phone drains really slowly in standby, but 4 hours screen on time during a regular day looks to be quite ok.
Web browsing is particularly taxing on the battery, because of the high res display.
Do not expect the same battery as on G2, from my experience it is lower at least by 1/3 (I upgraded from G2 too).

What do you think about that? Everything looks normal to me, but I could be wrong.
I can also test this again with full battery from 0 to 100

Yeah, we will definitely need more than 10 minutes of data. You don't need to go from 100 to 0 though. Just get some data from a few hours of screen off time and show me both the kernel wakelock and partial wakelock info.
Edit: The screen off time doesn't have to be all at once. However, the easiest way I found to pinpoint my battery drain was to charge the phone fully just before bed, and unplug it overnight.

My sensor usage also strikes me as very high. Is there anyway to figure out what sensors are keeping the phone awake so much of the time?

I need to see your partial wakelock info as well. Those sensor readings alone don't tell me much. One thing to keep in mind: as you reduce the usage of pointless activities, the usage percentiges for other activities like sensors will rise, but this doesn't mean they are consuming more battery.
I also need to know how much of that time the screen was on/off. If your battery drained 70% in 10 hours of screen off time, it wasn't just your sensors, i can assure you.
You should also consider whether your battery is defective. If you get a good amount of screen on time with a full charge, the battery is probably OK. But if you can drain a full charge in an hour or two of heavy use, you might need to replace your battery.
Good luck!

Also try Wakelock Detector / Greenify - an amazing battery combo

Thanks for the response. Here are the partial wakelocks, captured at the same time. Unfortunately, I didn't capture the "Others" page, but screen on time was about 3 hours. Wake time was considerably higher than screen on time. I've rebooted the phone, in case something weird was going on. I see what these numbers look like tomorrow. If they still seem odd, I'll repost with all the relevant data.

Ok, here are my stats over night:

I've lost 4 percent of the battery doing nothing over maby 8 hours.
But the real problem is when screen is on, than I'm loosing 1 percent every one or two minutes. I'm out of juice in 10 to 12 hours with less than 4 houurs of screen. I'll show u my stats after full battery cycle. And I have two batteries, it's the same, so I guess this is not battery fault...

If your big drain is coming from screen on time, I suggest using gsam battery monitor to determine what's eating the battery. It's easier to read, and I find the stats a bit more relevant for screen on drain.
4% loss over 8 hours of screen off time doesn't seem bad at all, honestly. Its probably improvable, but not necessarily worth the effort.
What are you doing during your screen on time, and what screen brightness? I can burn a full charge in about 3-4 hours of Netflix at full brightness and full volume, but I get considerably more time if I'm browsing the web at minimum brightness.
Edit: I'd you don't use it, i highly suggest disabling or uninstalling google search. It's a prime culprit for wasting battery. I'm not entirely sure, but this might break google now, if you use that. Of course, google now is also a big battery waster.

Are you on WiFi most of the day? I'm just curious, is this a residential AP or are you on a corporate network? We recently upgraded our school to a Meru wireless network, and since then my battery will go from 100 > 50 in 8 hours, versus 100 > 80+ when at home, and at home I use it even more.
When I use BBS at work, the awake time is MUCH higher, and I also have very high sensor use.

This is mine with wireless on and sync on. Rooted and Unbounced. Removed some programs access to internet.
But when i use it it drains like normal.

I'm experience a huge draining in battery life just last few days. It was perfectly fine but not anymore. I have tried to factory reset with no luck. I have greenify at work.... I don't know how to read from better batt stats data so I was hoping someone here would be so nice to help me with that.
Here's the log file:

I'm not trying to steel your thread. But since we have the same problem we are search for similar solution....

Is it safe to disabling the services of google? My phone has v10c rom and can at most 3h of screentime.

If you disable Google Play Services you won't be able to use the play store or some other google apps. However, you can use Wakelock Terminator to prevent it from draining your battery.
I have frequently read that some wireless networks can cause more drain than others. If this is what's draining your battery I'm afraid I don't know of any good solution. If you have a good data connection and/or unlimited data, you may get better battery life using that. Have you tried disabling mobile data entirely when you're in Wi-Fi range? I have very limited mobile data, so I keep it off unless I have a specific need for it. I do think this has improved my battery a bit.
Again, i suggest getting gsam battery monitor. It's free on the play store, and offers an easier display of what's eating your battery compared to BBS.
Edit: don't get discouraged if you have some trouble getting your battery life up to spec. It took me three weeks of googling and tweaking to get mine where I'm happy with it.
