I've been running TeamEOS on my Xoom for quite some time, and it's been great. However, recently the device's battery life has become incredibly poor. For example, today my Xoom has been unplugged for 8 hours 47 minutes, without being used at all, and the battery is at 61%.
Previously, the Battery usage settings view was showing the Wi-Fi in use all day, but today I turned Wi-Fi off and it is still the same. The 'GPS on' line shows one small section of blue (about 10 minutes) and the 'Awake' line shows a few times it has been awake, maybe half an hour in total.
I installed BetterBatteryStats and the longest Kernel Wakelock is PowerManagerService, for 2m 2s, the longest Partial Wakelock is ConnectivityService at 57s.
Under 'Other' it shows that the device was in Deep Sleep for 8h 39m.
Another odd thing is that when I first unplug the device, I get a kernel wakelock on cpcap_otg. If I don't do anything the battery drains even faster than it did today (it never goes into Deep Sleep), but if I plug in my USB card reader (without a card), and then unplug it again, that wakelock doesn't happen again, extending the battery life slightly.
I have a Wingray Xoom (MZ604), and I currently have TeamEOS nightly 114 installed. I have tried various nightlies, back as far as 90, and have also done a factory reset, to no avail. I haven't yet tried going back to Honeycomb, although maybe I should just to check, as it certainly used to work fine under TeamEOS 1.0.
Does anyone know anything else I can try to do to fix this?

Battery life seems to be so device specific that it's really difficult to diagnose, tho you seem to be looking in the right places. I'm on 114 as well and my battery life is fine...normal for my device, depending on use. It is said that you need to let a new rom install settle a bit, and I've been told to flash a new rom with a full charge...other than that, I don't know.
It could be some app you recently installed that wakes up your device wifi and consume battery. To diagnose more, get betterbatterystat app.

He said that is the app he is using. I'm sure, as you said, it is an app causing either wakelock or something syncing in background.
Are you syncing Facebook? I uninstalled the app a long time ago and battery life went up.
Tried wipe battery data in recovery? That may fix your battery issues.
kinda old thread, but if you are still facing battery problems, try this.
go to settings/wifi/advanced and choose never for "keep wifi on during sleep"
I had the exact same problem and it turned out that the device gets a wakeup call from the wifi router every now and then, which keeps it from entering deep sleep mode, resulting in horrible battery stats, running dry after about 1,5 days of just laying around.
Since I did the setting change, my xoom lasts for almost 1,5 weeks at light to medium use (mainly browsing and email) now

true, but don't forget that will also kill your apps from keeping their state up to date. email push won't work anymore. it's a matter of what you want, i personally rely on the phone for incoming mail and use the xoom for reading with disabled wifi during standby. it's the best of both worlds, instang notification and long battery.
oh, of course you´re right.
I didn´t thought that this could be an issue for other people.
Like you, I get my mails on phone and work on them on tablet.
Like you said,best of both worlds and feels so natural
But I still say, if you can sacrifice the "always-up-to-date" satus on your tab, just do it cause the battery uptime afterwards will be totaly awesome.
Does anyone else have the issue where android system is consuming 35+% of the battery? Looking at the stats it seems like one of the bundled services is keeping the radio on for 14/18hrs its been on.
Have the same isssue
Yeah, I'm having this issue too. Android System is consuming HUGE amounts of battery for me.
Thought I was the only one but glad that's not true! Still got good battery stats with the android system drain nonetheless.
Charged mine to full last night right before hitting the sack.
Woke up 7½ hours later and it had consumed 33% of the battery just sitting doing nothing bar getting email & polling (presumably) for Facebook updates.
And that was with Power Saving enabled. Bit disappointing, hoping when I disable auto-sync that it'll kill the drain.
There's lots of services running under Android Systems disable the ones u don't use, I have disabled some got better battery life, still testing some others...
The hardware on the phone is great, but touchwhiz drives me up the wall. I'll be happy if and when we get anything AOSP based, CM being the holy grail. Nice to know I'm not the only one getting this battery drain. I've disabled pretty much everything that's able to be disabled, as all I use is google services.
Same problem here.... Huge Android System battery drains.
I've played around with several things, and as of yet I haven't gotten it to stop other than turning off WiFi. Anyone found a fix?
Mine's more a combo of Android System and Google Services... both take up a majority of my usage... Services typically being a bit more.
Why are there two android systems? wtf...
Is there any way to reduce cell standby?

Same sh*t here. Went to bed last night fully charged, and 7-8 hours later, wake up with 23% of my battery gone.
I'm starting to wonder if moving away from the Nexus line was a mistake. I started running again and the N6 was just too big to lug along with me, on arm or in a waste band, so I decided to try Samsung.
Just got my S6 and I noticed this right away. Last charge I had 2:42 of SOT and "Android Systems" used 47% of the battery. I was just watching Netflix and YouTube mostly. My overnight drain is also quite high, about 1% every 30-40 minutes of standby.
Is that normal for most S6 owners?
To all:
Turn off VoLTE, turn off WiFi calling, install CPU Spy, ensure your phone is going into deep sleep. If it isn't, flash the stock recovery with Flashify, wipe the cache with it, then flash TWRP back with Flashify.
Post your results.

Is this only for people who already flashed TWRP? I'm stock rooted and seeing this.

This is for everyone. If you haven't flash TWRP, then simply wipe the cache with stock recovery.
I just assumed most people would have TWRP flashed, my bad.
I am guessing that that this is an Android problem as the Galaxy S6 Edge has the same problem with battery drains.

I'm not rooted and I don't plan on doing so. I'm not sure of any other options. I unplugged it last night an let it sleep. Android system used about 14% of the battery. And I lost 20% charge. Cpu run time was 38 minutes too. and I never even woke it up post unplugging it.
I believe this Battery Drain Issue is a Lollipop issue. Was haing it with my One Plus One, I fixed it by going into privacy Guard, and going to Google Play Services and not allowing it to stay awake, and start by itself.
Ill find the actual thread and post it, same issues happening with a lot of phones using lollipop
Battery drain on a new device = bad flash (very common on android devices, first run)
1 wipe the devices and start it again from factory problem should go away. (at least the excessive drain anyway)
2 Ensure you have updated the Samsung Services app (this was responsible for most if not all battery drain issues if you reset your device)
3. Turn the bloody Screen brightness down and turn off Adaptive display (way way way too much battery drain using them)
4. LTE off and Cell data off if you on wifi, your wasting battery power communicating with cell sites you arnt using, the weaker the signal the more power you will drain for no benefit
6. GPS / Loc data off unless you need it even then wifi / AGPS is usually more than accurate, remember GPS + poor sky visibility = more power used to get a loc.
5 NEVER measure battery life for the first 24 hours way too much stuff syncing and updating to measure with any accuracy.
I get a solid 2 days out of the S6 with mixed use and a screen on time of 2:30 could get that upto 3 hours but i have a hearthstone addiction
As mentioned above, I highly recommend wiping the cache, even when not rooted.
Also, worst comes to worse, i'd completely redo the phone from scratch via the Smart Switch software samsung provide.
I have a serious issue with my Xperia L running 4.2.2 stock, rooted rom. The battery drains extremely quickly without me using the phone. Today I took the phone off the charger at 7 am, and at about 12 pm with only 20m screen on time the phone had already shut itself down. During this time only my mobile data was turned on for about 40 minutes. Also the phone gets very hot in my pocket doing nothing (40 degrees C). I really have no clue what do, now my phone is practically unusable. :crying:

please loom gor background processes
try the following:
shut phone down
restart
while seeing sony logo (after recovery led) .... hold vol- .... let it hold until system boots
you should be in safe mode... if the phone works fine in this mode... its your system
you should now

Oddly enough now the phone works normally. I think it is something to do with the stock rom, because i have 2 batteries and with both the situation is the same.

ok if safemode is stable... then try to clean install stockrom
Sent from my Xperia T using XDA Free mobile app
Okay, so I did a clean install of the stock rom yesterday and the problem persists. It drains a little slower now, but still - I don't think that from 74% to 10% in 3 hours is acceptable. I noticed something really weird - the drain happens only when i'm not at home. Even if my mobile data is turned off, once I go outside the phone starts to get REALLY hot (~41 degrees) and battery starts to drain extremely quickly even without using it.
I really have no clue what is going on. Can it be a hardware problem or something?
I've been experiencing battery issues lately and I struggle to find a solution for it. When I first bought my Xperia Z3, battery was wonderful and was lasting over 2 days with moderate usage. Now, I am forced to charge it every night and it often dies even before the end of the day.
Every night, I charge my phone to full before going to bed and notice in the morning that 30% of the battery get drained overnight.
Since then, I have tried many things but it didn't solve my issues:
- Did a factory reset
- Disabled every widgets
- Kept apps to a minimum
But my battery is still draining overnight (and in general).
I installed GSam battery monitor and it seems that no specific app is draining the battery.
Here a more pictures for details: img ur.com/a/eqsuq#0 (copypaste as imgur, can't post link yet as I'm a new user )
What could be the source of my issues?
I'll be so happy if you could provide me with a solution. Thanks!

what firmware are you using?
I had the same problem after flashing a pre-rooted stock 5.1.1. The only solution I could find was to do a full wipe and flash a pre-rooted 5.0.2 now things are back to normal for me.

I'm running stock 5.1.1, unrooted. Never flashed anything before.
So if I understand correctly, you flashed a 5.0.2 and then let it update itself to 5.1.1?

no I flashed a stock 5.0.2 and have stayed on that. Disabled software update so I don't get OTA updates. Everything back to normal on 5.0.2. Won't update until a stable Marshmellow comes out. For me heat and overnight battery drainage problems made 5.1.1 a nightmare. 5.0.2 is rock solid.

I see. Damn that really would be a last resort for me, seems like a lot of work just to resolve the battery issues. I hope someone can come up with a fix because surely the Z3 is working perfectly under 5.1.1 for most other users.
I have seen the battery drain pictures and i see there is a solid blue line awith the Wifi awake option. I have experienced it before.
What you need to do is perform these steps and then report back.
1. Go to Wifi settings>Advanced>Disable "Scanning always Available".
2. If you don't want to recieve notifications when screen is off then also set the "Keep wifi on during sleep" to ALWAYS
3. Enable Stamina mode and use EXTENDED STANDBY
Check if the solid blue line cuts in between when screen is on and off.

Update on the situation:
You were totally right. My phone lost less than 2% overnight after following your steps. Moreover, the battery has been great so far with moderate use, standing at 60% remaining with more than 2 hours of SOT (2 hours SOT put me at around 30% remaining before).
Thanks a lot! Strangely, the history details screen still shows Wi-Fi as a solid blue line.
Here are some screenshots: img ur.com/a/zqG0E
First part shows the stats when I woke up in the morning, second part shows stats at the end of the afternoon.
Ideally, Stamina mode wouldn't be required but I think this is a good compromise until a fix comes up.
EDIT: After a second night in Stamina mode, it appears that I lost 30% overnight again. The only significant change I can think of is the fact that I added Whatsapp as a standby app so that I can receive messages when my phone screen is off. I will try to remove the app and see how it goes tonight but if I cannot put Whatsapp as a standby app at all, then it will be terribly inconvenient to not be able to receive messages instantly without having the screen on.

Sorry for not responding to this post. Just got back on.
So whats the update? Hows battery life going?
i havent put whatsapp onto the list for standby apps and i get messages fine when the screen isnt on
Hi dear XDA users!
I'm having a problem with my GS6 that sometimes, even though I closed all the apps running in the background and restart the phone, it becomes really really hot when in standby.
I don't know what to do about it but wait until it's over, which can take a long time and drains my battery a lot....
For example, I went out to get some Takoyaki (Japanese Squid balls) and left my home with 56% battery left.
It took me about an hour to get the Takoyaki and get back to my place, and my battery died before I could even hop back on the scooter to head back home.... Before dying it had this same problem that I described earlier, that it was becoming hot.
I was using google maps for a 1km drive, so I wasn't using it that long.
Then I decided to install a new rom, and rooter my phone (up until now my phone was never rooted before). I installed the rom, wiped cache etc. but it didn't help.
I am having serious battery drainage issues, I believe, and I was wondering what was the best ROM to save battery and which app would accommodate the rom well, to optimize battery even more.
"Turn down your screen brightness" isn't one of those advices I like to follow cause I like to keep it on automatic brightness so I can still see what's on my screen when I'm outside...
Hope you guys can help! :highfive: :good:
Thanks
Nathan
Irrelevant update
Today I'm going to get Hotcakes for lunch, which is much closer than the Takoyaki place, and I'm leaving with 96% battery! :silly:
I might have solved the problem myself, so if you are having battery issues with the Samsung Galaxy S6 and don't know how to properly fix them, try this out:
(NO NEED TO WIPE DATA ON PHONE)
Install the Rom "Tyrannus"
Install Greenify and forget about it
Install Naptime and set it on "agressive doze"
Boot into recovery and wipe all cache
