Battery draining while sleeping? Try this!

This works in VegaN - YMMV...
Settings -> Wireless settings -> then hit the menu button, and choose "Advanced", then select "WiFi Sleep policy" (It was set to NEVER!)
Spare parts showed (via 'Spare Parts' app) that the WiFi was on 100% of the time - even while sleeping..

I'll give this a try tonight when I go to sleep.

I like to leave it at "never" so that there is no delay upon wake up to connect to wifi. With the table in use (vs. sleeping) the battery life is so long; almost 10 hours, I don't worry about a little battery drain while sleeping. Just connect it to the charger once a day or less.

You get a 'little' battery drain while sleeping? If I leave my gtab unplugged overnight, it loses about 4% per hour.. or about 30% overnight. That's why I'm trying different things. 30% overnight isn't a little to me -- it's way too much.
A tablet like this should all but go into a state of suspended animation while sleeping...

30%, really? That sounds as if there's something else going on rather than just wifi draining.
Edit- Some thoughts. There are some apps that require permission to update or snag some ads from the net and operate on their own.
Go take a look at what you have installed and look at your screen timeout settings.
If you have CWM and can get to recovery, wipe battery settings and then reboot/charge. Some people drain completely then charge to get to 100%. Some threads seem to show this is a Vegan issue. (Mine gets to 97 tops but as long as battery life is not affected, I'm good)

Just curios, why would you leave it on all night when it will never be used? it only takes a minute to boot in the morning when you turn it on.

I leave it in sleep mode because its my alarm clock. I also now leave it plugged in.
I've tried draining the battery then resetting stats in clockwork. If tried about every variation of doing that I can think of short of waiving a dead chicken over it.

I've left mine on and unplugged(it went to sleep) for 3 or 4 days and come back with battery still. 30% overnight seems odd.

I think you might be right, because I used Cyanogen Mod for a month and a half and had no issue like this. Now I am using TNT Lite 4.2.4 and I am still having no battery life issue.
Also I have never been not able to charge my Tab to 100%. So I may suggest that you guys try switching to cyanogen mod or tnt lite.

Battery issue after 4.1.2 update

Recently I've updated my Note through OTA to 4.1.2.
I've spot that after update the Note is just draining the battery.
I could read about 10 hours on it before, and now it is only about 6 !!!!!
I even do not mention gaming, which is draining the battery in 2.5-3h from 100% to about 5%. I could play approx. 5-6 hours before.
It's ridicules.
Did any of you spot the same thing?
I haven't installed any additional apps after update that may "help" to discharge the battery.
The values above are based on Screen usage time in Battery menu.
Any suggestions?

After the update, I'm facing recharging issues. The tab is taking twice the time of what it used too to recharge to 100%.

i haven't spot any issues with charging.
.

Same here.Used to get 10 hours of screen on time,now i am lucky if i get 8 hours!

Same here...
Some tips :
Kill all apps, switch to offline/airplane, and power saving mode when charging..
Still not working?
Try reboot your device once or twice if necessary..
And your device will charge normally
Work on my gnote...
I hope it will work for you too
Correct me if i'm wrong

Im using juice defender with good results, I lost a pretty noticeable amount of battery time after 4.1.2, too.

Maybe a problem with the battery stats?
Try to drain the battery empty and full charge afterwards.

It will damage the lithium battery when you drain it till empty

I think it is Wi-Fi that drains the battery !!!!
Usually I was leaving the tablet with wi-fi on all the time. After 4.1.2 update it takes approx 2% of battery per hour !!!!!!!!!! when you do not use the tablet but wi-fi is on, so after night in the drawer you had approx 10-15% drained.
When I turned the wi-fi off and left it overnight i haven't loose even a 1% during the night !!!!!
I have to try to work on it as usual but with wi-fi turned off, it will be difficult though as usually i play on-line or browsing the net
I think they f#^%*d something in 4.1.2 update with wi-fi energy consumption. hope they will repair it in next update.

I mean, just let the device turn off by itself, and after that, charge 100%.

Yeah, I had this problem after I updated too. It was also laggy. I did a factory erase and now it works better. I think it is still draining more than before, but not as bad as after I updated. I think a good rule of thumb is to wipe everything after an update and start all over. You could also try wiping and flashing the rom for a fresh install.

I suggest you to change your rom to germany stock 4.1.2...
It will solve your charging problem

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.

poor battery life?

Hi,
I received my gear S2 classic yesterday but I don't seem to be getting the battery life of 2 days. I took it off charge this morning at 11:30 am and it's now 12 noon and it's down to 89%. Is this normal? I've turned off the auto heart rate monitor and NFC and Wifi. It's constantly connected to my note 4 and the brightness is set to 5.
I've had a fair few notifications and haven't really used apps on it today so far but seems to be draining quicker than what I was expecting, just wondering if this is normal or not? I understand it's a small battery but when it's supposed to get 2 days and it doesn't seem like I'd get one day out of it if I was to take it off charge early in the morning like at 8 AM for example.

In 30 min it drained 11%? Seems like a lot. Restart it perhaps? I have wifi off, s voie off, and screen brightness set to 5 as well and it lasts 2+ days. I'd give a couple more days, if it doesn't improve then I would exchange it.

Think it's okay (ish) been off charge now for about 11 and a half hours and it's at 46% though this still is only barely a day of battery life not 2. Should be able to live with it though I normally put my phone on charge at night when I go bed anyway regardless of the charge I have left and I do the same with the S2. Speaking of phone is there anything I can do with it's battery life? Having bluetooth on 24/7 really takes a hit on my battery life on my note 4. Is there anyway I could put it into some kinda low powered bluetooth mode so maybe it's not quite as fast but still some kind of connection?

I had pretty bad battery life with watch connected too. It turned out it was a misbehaving app with bluetooth, GasBuddy in mycase. Uninstalled it and battery life went back to normal. I suspect something similar may be happening in your case.

+1 for the misbehaving app as the likely cause. For comparison: My Classic goes on at 9am and off around 9pm with about 60% left, consistently. Connected with bt...Wifi off and max brightness all day.

How did you determine the app causing issues? Do you have the clock always on or gestures on? it seems i am draining awfull fast too. Took off charger at 7am and now at 10 i am at 85% is this normal?

That drain seems a little fast to me but not too bad compared to the experience of others posted here.
Usually you'll notice the drain soon after installing troublesome apps, so the offender is likely one of the last few you installed. To fix this I just uninstall the last few apps I downloaded and test from there. If the battery issue is still not resolved after a while of usage, then I uninstall the ones before it. I don't know of any other way to test on the Gear S2 like we do on android phones (e.g. with bbs, wakelock detector, etc.).
The battery life I mentioned for my Classic is with gesture mide turned on, and always-on mode turned off.

Standby drain

When you sleep, does your phone sleep, or does it stay up all night and crunch 1s and 0s? Rate this thread to express how you deem the speed at which the OnePlus 5's battery drains under standby conditions. A higher rating indicates that when the phone is not in use, the battery drains minimally.
Then, drop a comment if you have anything to add!

I am not too pleased about idle battery drain.
Overnight, about 8h it consumes about 3%-5%. Sometimes more than 10%, if the device doesn't go in deep sleep for whatever reason..
If commute, it takes more battery (maybe sensors, switch to mobile data, etc).
About 20% in 9hours. wifi most of the time with about 1h hour on mobile data. And movement in pocket about 20-30mins.

My experience with idle drain has been good overall. Getting around 0.5% per hr

My idle drain is horrendous. I'm getting around 20% drain over night (7h sleep) with nothing enabled but WiFi. And that's with Greenify. I'm thinking of rooting and flashing the EX Kernel, but wanted to wait for an obviously outstanding major update before doing so.

Android System, Phone Services + Google Services, but only if WiFi/data is on. If they are off the battery life is perfect.

Battery was good until yesterday, 8hrs SOT circa. Suddenly battery starts draining and can I barely reach 2,30 SOT. Any idea? No apps showed in battery page, the only app I downloaded yesterday was Textra SMS (Beta), but it's very strange that it can drains so much.

For me Chrome was a big culprit for battery drain. Try to delete the cache and the storage of the app. You can as well disable and it and re enable it. That should be enough. Anyway, Chrome is a battery hog. I am thinking about switching to Opera or Firefox. Any recommendation for browsers?

I use Firefox with the add-on 'Dark Background and Light Text'. I have it set to turn the background of all pages to true black.

2% over night (7 hours) pretty pleased. But it was even better on OP3 when the drain over night was 0-1%

I'm on RR with no GAPPS and lost about 1.5% in about 8.5hrs of not being used (sleep + getting ready in the AM)

I have TASKER, and have set airplane mode to come on 8pm - 3am.
Currently getting roughly 2-3% drain in that "airplane mode" time

What the? Do you have gestures enabled (eg: double tap to wake)?
In my opinion it consumes too much.. one time i got about 3% drain in about 8-9h idle with wifi on and no commute.

That's why i hate android idle drain. A never-ending issue.
SOT only 34 mins, 1h mobile data, the rest on wifi.
I've disabled gestures, location history, no google fit, etc etc

Not bad here. About .3% per hour overnight. So about 2% overnight. That's on 4G as I rarely ever have my phone on WiFi. I also have email at to push (2 accounts) and I usually turn off the sync stuff in my Google account. Things like app data, calendar, contacts and the rest. I just sync when I make changes like adding a contract I then toggle the contacts on then off kind of thing. No need to let it sync all day and night for nothing imo.

I just have that drain when location is set to "high accuracy". When its set to "battery saving" everthing seems fine.

I don't know what's wrong with my device/apps. Several times now i had a standby drain in around 7 hours of 30%+. I didn't plug my phone in overnight because of Dash charging, when I went to bed, the battery was at 37%. The next morning I overslept massively and completely missed my shift because my battery died over night. This is with airplane mode on during 75% of the night. The highest drain in battery settings was displayed for "Android System" with around 12% or so, but that was with the last day counted in. I feel like the battery drain stats in settings are completely unreliable...
Except from that I get normal battery life during the day though, although during the first few days standby drain was higher than screen on drain...

Yeah man you need to download accubattery or something to monitor the drain. That's ridiculous. And yeah I've been kinda confused about the stock battery stats as well. It seems to tell you nothing.
I have noticed a lot more battery drain since the 911 update a few days ago. I was getting 7ish sot now I'm under 5hrs. I'll bet I'm not the only one who noticed it though. It'll be fixed don't worry.

I had AccuBattery installed at first but it didn't give me any meaningful insights so I uninstalled it a few weeks later.
I normally only get around 3 hours of SOT, but I'm not into mobile gaming or YouTube so that is normal...

I notice significant drain in idle after the 4.5.6 update last week. Android system seems to be the culprit, but not sure what's process under this is actually causing the problem.
All radios on, and 2 mail accounts syncing.
