Android OS battery Drain on 6210 - Samsung Galaxy Tab Plus

I don't know why this is happening... and I am doing quite a bit to try and alleviate it.
When I first got this tablet the battery was fantastic and it maybe used 2% over night when I slept. Now in one hour it can use 3% to 4%.
I have done the whole 9 yards of flashing back to stock, factory reset, all of that.
I sent this in recently to Samsung since I was having SOD issues and told them to fix this problem too but they fixed my SOD problem but not this one.
When in the battery use area in setting android is using any where between 12% and 40% of my battery with over 10 minutes of CPU time. When I first got this tablet android OS MIGHT have used 5% on a bad day.
I am saying this is the problem in terms of my battery but any input would be appreciated.
Edit:
Here is a screen cap of my battery usage (ignore that white line on the graph that was when I flashed LA3 back on to the Tab)

Foyo update...Battery life shortened ?

Has anyone noticed their battery life seems shorter since the update ? I installed the official froyo update last night and it seems I'm running out of juice much quicker than before.
At first mine ran down faster. I ran it all the way down. Charged it. And ran it all the way down again and charged. It seems back to normal.
I didn't have any issues. Maybe you changed something else as well? Could always try a few recharge cycles and see if it stabilizes..
I was running the leaked 2.2 and I flashed to official 2.2. My battery life is almost double what it was. I can't complain one bit about battery life, although I have other gripes with the official Froyo release.
I'm with icepop on this one.. I was running the stock rogers rom pre-update and now with the official rogers 2.2 I'm getting at least double the use before having to charge again.
I'm having battery issues with the new stock Froyo. I lose a huge amount of juce when in standby. I thought I may have my widgets updating too often so I charged it up and put it into airplane mode last night. The phone lost about 1% per hour in airplane mode. IDK what is normal but that seems like a lot to me. I didn't have any apps running, except my alarm was set for the morning.
I have SystemPanel installed and my cpu load NEVER goes below 10 percent, even in airplane mode. I suspect this is a large part of the issue. In app history, system and system processes are always on the top of the list and are around 3% each. IDK what controls this or how to lower it. I would love some feedback from someone else with SystemPanel just to see how our numbers compare. Overall the battery life I'm experiencing is pretty terrible and a buddy of mine's Fascinate has much better battery life (hence something must be wrong somewhere). He and I were skiing all day over the weekend and when we got back to our cars, my phone was half dead and his had lost almost zero juice. This displeases me.
mine's was better actually. but i didnt stayon it for long
My initial results with 2.2 were very bad (10% drop per hour when idling). I reset the phone back to 2.1 then re-installed 2.2. This did not help. Now I did this again (2.1 then 2.2) but this time I have not re-installed my apps and have not rooted (yet). So far, battery life seems to be normal. I suspect that some of my applications might mis-behave when installed on 2.2. I am planning to add them slowly and watch the battery.
Not here, seems the same to me
Mine is terrible ! I don't know what it might have been on 2.1 as I upgraded fairly quickly. Essentially I charge all night and then disconnect from power at 6:30am and then by 4:30pm I'm out of juice (phone shuts off). Any ideas here? I'm not running anything extravegant (email only) and hardly make any calls.
Whenever you flash to a new ROM, wait for at least a week of normal usage before you judge the battery life. The reason is simple, your battery stats are reset after ROM flash and your new OS needs time to learn how your battery drains before it can give you accurate readings.
If you can't wait for that long, you need follow the battery calibration thread to force a manual calibration of the battery.
I'll give it a week and see how it is then. Definitely is draining much quicker now though. I think It acted similiarly when I first got the phone as well. If I recall correctly the batter life sucked when I first got it, but then a week or so seemed to get much better.
I did the manual battery recalibration (let it die, charge while off, turn on and bump charge...etc). Last night I lost about 2.5% of battery per hour while in standby. This seems improved since calibration but its still pretty terrible IMHO. Is this in line with the amount of drain other are getting or am I draining more than usual?

Running stock since purchasing the Captivate back in August, and so far battery life actually seems to be routinely as good if not better than 2.1. I must admit I didn't use my phone a huge amount yesterday (except for about an hour plus of downloading a bunch of wallpapers off Zedge for some ungodly reason lol), and after 18 hours of the phone being on I was still over 50% battery life left. 2.5% in standby doesn't sound like all is well - you must have something running in the background or similar issue. I have a live background, sync 5 e-mail accounts (granted, only one of those is every 15 minutes - the others are every thirty minutes, every hour, and once a day on two of them), and with light use I am getting over 40 hours with 2.2 so far (about in line with 2.1, but seems maybe just a little better). Heavy use I am dropping more like to the 12 - 18 hour mark (heavy use for me means the screen on more than off, actively playing games or using apps, large amounts of texting, etc. Solid game playing I haven't figured out a drain yet, but on some games it seems like I can drop almost the whole battery in close to 10 hours). At your rate of 2.5% per hour in standby you would only make it forty hours without even using the phone. I have been using mine just a little this morning (FB check, logging in to one of the desktops at work remotely to make some changes, live background running, WiFi sleep policy is set to when screen is off, but to be honest that is about it) and I haven't moved off the 100% mark yet and the phone has been unplugged over an hour and a half.
All that said though, as other users have stated you might want to give it a little more time for the system to recalibrate the battery usage. I would definitely check your processor usage though regularly to see if anything seems 'off'. One thing that caused me problems was that my SNS service would be running but then would get stuck in a pattern of 'Restarting' - would drain my battery rapidly.
It has been said that bettery drain is not linear. First 5% goes real fast. So, you need to judget the average over a day of use, not first hour or so. I'm still in first week of ROM flashing. So I can't confirm anything yet.

Faulty Hardware Battery drain?

Hey everyone,
I recently upgraded to android ICS 4.0.4 from 4.0.3 with the hope of the battery issue no longer an issue with my nexus s...
Though my battery drains around 1% every 2-4minutes with normal use, as in just scrolling and going through settings (not using apps), very very light use. I have factory wiped it , I have installed new roms and kernels - mixed and matched, uninstalled apps and installed apps one at a time (to see what drains), I even disabled some the high % wasting applications...
My screen dim is on the lowest, wifi is off, data is off, sync is off, gps is off, screen rotation is off, yet still no improvement, I even fully discharged my battery and re-charged it (while phone is off)- no improvement. And i also changed the CPU settings to 800max and still no improvement.
and when i'm playing a game or something it drops around 10% in ten - fifteen minutes, sometimes drops more.
When my screen is sleeping it takes around 1-2% every 1 hour-2hours, which I think is normal.
My screen is usually 45-50% Battery used by the display and backlight
Android system is usually 15%-20%
Android OS is usually 3%-10%
My battery is only about 4-5 months old, and I've always charge it when its 5-10% left, I don't let it die. I'm going to purchase a new battery to see if the problem occurs, if it does, can it be something with the phone hardware?
But any suggestion on what it is?
I've looked around on forums etc and none of the solutions have worked.
The display is going to use the most. There is no way around it. What are your average use times? If you're only losing a few % an hour idling, that's great! The only things I can think that would help is using black backgrounds whenever possible. You also have to keep in mind you're gaming with your phone and that's CPU intensive, which will cause more drain.

Yeah the display will use the most, but I remember it used to be around 30-35%, I've just been seeing how the battery is lately - just going through settings etc and it goes down every 2-3 minutes by 1%, it used to last much longer than that - 1% every ten mins. Sad thing is - I do use a black background lol to save battery and with games I hardly play them but when I do bye bye battery.
try battery callibration apk from market before you recharge your phone and no use 3g just 2g and make conservative 100/1000 the governor.

I'll try the battery calibration and see how that goes, and change the governor as well to see if any improvement.

Yesterday morning i charged it full 100%. I took it off the charger and left it on the table. It had no wifi or games running at all( at about 8 am) I leave it there all day until about 6 or so. and when i come back its down to 30% WTF IS THAT!. On my dads phone he could have 1% battery and leave it standing by all day and night and he can still turn it on without losing the last percent. Its not an iphone either. Hopefully 4.1 Jelly Bean will have some battery fix for the nexus
BetterBatteryStats. Your best friend when it comes to battery life.
Yeah. Mine isn't bad, but I also just go by my screen usage. If can't get at least 3 hours by the end of the day(which is probably 13 hours), then something is up. Note on calibration, it won't do anything. Those stats are reset once the phone is charged past 90% IIRC. On top of that, our batteries have a different way of reporting the charge. It's not the same as htcs.

I managed to get my screen down to 40ish% and my Android system is under 10% and I've been timing my battery and noticed every 4minutes exactly it still goes down. I tried calibration does nothing as you said. I'm gonna download betterbatterystats and I have cpu spy running atm...

I have the same issues. 10 hours max not touching the phone at all. Stock, custom, matrix, nothing helps.
Maybe 6 hours if I start using it moderately

Similar issue here. Tried all combinations of ROMs (jb,ics,gb) and kernels (air,marmite,matr1x,lucid) to no avail. Even reverted back to stock GB ROM, radio, and bootloader. Nowhere near 6 hours talk time or 200 hours standby time. I get between 8-10 hours standby time if I'm lucky. I even tried turning the phone off overnight, with a full charge even, and when I went to turn it back on in the morning the battery was dead and I had to plug it in to turn it on.
I picked up a new battery today but the issue seems to persist. I put the new battery in at noon with 98% charge and now 2.5 hours later I'm down to 70%. I am convinced there is a hardware problem that is causing the battery to drain excessively. GSAM Battery Monitor and stock battery stats all look normal with screen using the most battery followed by Android System etc etc. Aside from the battery problem, the phone is awesome and I really don't want to have to buy a GNex when this phone is still salvageable.
So what part of this phone could drain the battery so fast with the screen off? It could be the CPU, GPU, screen digitizer perhaps?
I know you tried with your old battery, but could you try again with the new battery with your phone turned completely off? If there's a drain, then there's definitely a hardware issue.

Phone off for half hour yielded a 9% drop in battery life. I'll keep the responses in this thread only. I just realized every time I respond to a thread it gets bumped to the top of the forum!

Definitely something wrong. I don't lose anything with phone off, so something is messing up hardware wise. Did the phone get water damage?

Bad Battery life or Bad Battery on Nexus 5 with 5.1

Hello,
I've searching for like 2 months about problems with battery life and Lollipop with nexus 5. I understand the issues but since it was released, i never had much problems with it. I used to have 2h SOT for like 40% battery or so.
My daily routine allowed me to reach home with a bit more than 50% battery with 2h SOT more or less. (a lot of messaging on viber/whatsapp)
But something changed since 1 and half months ago. I can no longer do the same and it seems that i have a CONSTANT battery drain. I remember when i unplugged my phone i would reach my workplace (1:30h after unplug) i would have like 2-4% less battery depending on the usage. Currently when i get out of home the battery is already at like 92% or more depending on the usage. If i let the phone stay idle all the time, i usally get home with 30-40% battery now. I'm already thinking that my battery has gone bad. This started to happen from one day to another and i never let the battery stay too much below 30% usually, but nowadays it's impossible to predict the battery life since some days it seems to drain more than others.
I've used some apps to monitor the usage but i really don't understand much about it and can't seem to find a pattern. I've already did factory reset with all Lollipop versions and i remember doing a KK regression for some hours but the drain seemed like it was still there (can't use KK on my nexus 5 anyway, it feels weird after Lollipop experience ) but i didn't even fully charged the battery as i remember. Anyway if it would be an app, there should be some kind of logging in battery stats which doesn't, and i can't think about anything else.
I finally gave up and decided to ask help here, since i don't know what else to do. I'm actually leaning towards getting a nexus 6 but after reading about so many issues (screen/battery life/burn-in) i'm not sure what else i can do with my nexus 5.
If anyone can give me a hint i'd be very grateful
PS: already tried Cataclysm ROM and using currently ElementalX kernel. I notice a bit better battery life with ElementalX but i think the pictures speak for themselves.
Judging by that constant drain with very little shown awake time I'd install Better Battery Stats and check for kernel wakelocks. I had a similar situation with a wake lock from using a wireless charger that did not show in the regular battery stats.

i already installed it before, but currently don't have it installed. I have Wakelock Detector app i can post a screenshot if helps
Installed Better Battery Stats, i'll post results tomorrow (battery at 19% already).
As promised, there's still some battery left but i didn't even use the phone today mostly... in days like these i should be over 70% as usual or maybe close to 80% that i remember.
Can't seem to find the cause
bump i guess
will some full discharge cycles fix this ? iirc that can make things worse.
I feel your pain...when I was on Kitkat, I'd get to work running just Waze and Pandora and my battery life would be at 80%. Installed Lollipop 5.1 and now half way through my trip (15 minutes of use) the phone shuts down with a dead battery. Maybe it's just a coincidence that my battery decided to give up the ghost at the same time I install 5.1, but I find that very odd...the phone is only a 1.5 years old...lithium battery's tend to last 2+ years and even then they don't fall off a cliff in terms of capacity. At this point I think I'll buy a new battery and see what happens, LG OEM are about $25 on Amazon.

SERIOUS Battery Drain

i know there are a lot of other threads out there, but I haven't found one that talked about the problem deeper and has a fix. anyways, I'm experiencing a serious battery drain where I charge my phone up to 100, unplug it in the morning, go to school and leave it in my pocket for 2 hours, and it ends up being 70-80% and the screen on time isn't even on the battery stats because I've barely used my phone to have it show up. As im typing this on my phone, ive even lost 2%. Is anyone experiencing something similar and is there a fix for this? At 33% now, according to the battery usage, cell standby is at the top of the list with 10% and screen on time is 25 minutes . Thanks so much
Please post some screenshots of battery stats and someone may be able to help

My phone is the same way. Even with the latest update that made cell standby way better where it sits at 1-3% my phone drains like crazy. It's been off the charger for 3 hours and 1 hour of screen on time and it's at 57%. They need a bigger battery in the s7.
Check to see if you have a VPN app installed, Firefox, Candy Crush (or other King app), or a weather app. Many use mdnsd that eats power. King apps send data all the time. And there may be some adware that you have that is eating power. Hope this helps...

Battery Drain
I have had the same problem. With the earlier update I had the issue with (what I consider) excessive drain caused by cell phone standby. With the latest update cell phone standby has taken a back seat to Android System. Here is a screenshot from today. As you can see Android System has more than twice the percentage of anything else. I reset the phone a couple of days ago but that had absolutely no effect. Went to a local Verizon store to complain which naturally went nowhere.

I did a factory reset in recovery wiped cache twice and rebooted I have had much better battery. 20-30% higher when I leave work. I also kept WiFi calling turned off not sure if that was the drainer.

Massive Battery Drain even when powered off

For the past few weeks, I've been having massive problems with the battery life of the phone (XT1955-4 RETEU2).
At first the battery would last for 3-4 days (Stock firmware Android 9 February patch) but now it will only last for about 12h, draining about 8% per hour, no matter if I use the phone or just let it sit.
Accubattery reports a deep sleep of ~90% while the screen is off.
Even if I turn the phone completely off it will lose about 5% per hour.
When I turn the phone off in the evening with 40% left, it'll be completely depleted in the morning with the battery LED lighting up when I plug it in.
At first I was on stock, then I unlocked the bootloader, hard bricked it first, successfully followed the guide by sluggedlemon (https://forum.xda-developers.com/g7-power/how-to/guide-recovering-hard-brick-t3989753) and then I checked out some of the custom ROMs.
Later I returned to stock and flashed OCEAN_RETEU_PPOS29.114-134-13_cid50 from lolinet.
Since then the battery life is disastrous.
I flashed the stock firmware again using the LSMA but that would'nt solve the high battery drain issue.
Then I tried to revert to OCEAN_RETEU_PPOS29.114-134-10 (February patch) but that wouldn't help either. (bootloader and modem couldn't be reverted)
All custom ROMs I tried seem to have the same problem now.
As I read similar posts about battery life issues after the April patch, I hoped that the Android 10 patch would fix it.
But even as the Android 10 update arrived and the June update soon after, nothing has changed for the better.
Is anyone experiencing something similar? Especially the battery drain when the phone is powered off?
Or has anyone an idea what could cause this issue?
Any help, advise or idea would be highly appreciated.

If it drains when it is off sounds like ur battery needs to be replaced I have a phone that dose that
It looks like there's something wrong with your battery. Maybe you should replace it.
My battery only drains a lot when the device is on standby. To avoid this I use the Naptime app. It helps a lot, you should try it too
