Rooting doesn't effect battery life.

You went down 13% in 4 mins -________-. Go exchange your phone, lmao. Or turn off 3G, Accounts & Sync, turn off brightness, and install JuiceDefender. See if that makes a difference. My phone goes down 1% in about 2 hours...

mine barley lasts until evening when I plug it back in... but thats just how these phones are. 1% in 2 hours is very unlikely unless you just don't use it and have everything disabled.

Rooting your phone alone has no advert consequences on your phone's battery life. What you do on your phone does

should i call samsung and tell them about the battery issue?

So you go 200 hours between charging? I find it hard to believe that you only need to plug it in every 8 days.

indeed what a troll

Just turning off push email/notifications can have a significant effect on battery run time. I doubled my run time by putting some reasonable settings on my sync intervals.
I refresh my exchange account every 15 mins during peak-time ( 1 hour off-peak ), Tweetdeck every 2 hours, all other accounts hourly. With moderate use I have no problem going 24 hours on a single charge.
Also be on the lookout for misbehaving apps. I had a single dormant streaming app sitting in the background using over 10% of my battery. I kill that app manually after every use.

As it's being said before, if you do not use your device you get excellent battery life out of it - might as well have a painted brick on your desk.

Mine lasts a bit more than half a day, but I use mu phone a lot for streaming, texting, browsing, a game sometimes. I think it is about average, I wouldn't sweat it. Still beats my old.nexus one in battery life

My battery last about 24hrs on average. I bought extra batteries and I have run each of them until they hit 1% and then I use and external battery charger, bought of of ebay, came with 2 batteries and a charger for them for 14 bucks, and i do have certian things i do that drain more than others, but for instance i watch a 2 hour movie, and started with a fresh battery, (99%) and when the movie was over I was at 73%, much better than when i first got my phone, but i also still use advance task manager which everyone says is bad for the phone, but i just use it and exempt everything that is used for normal operations, then it only kills the apps i have used and want to kill. now the settings does allow you to do this by each app, but i am just lazy and paid for the app back on my G1 days and it makes killing them in widget form so one click. i just tried to exclude all the things that the phone uses to operate smoothly, and kill the rest of the garbage apps, also you can try a program autostarts, i have it as it suggested it in the app forum sticky, costs a buck, but i used it, not sure how much it helps, but like i said all I have done and how i use all of my battery each and every use now gives me outstanding battery life. No 8 days or anything but still tons better than my G1 and i didn't keep much running like i do on this one. Also turn off auto brightness, and just use the slide if you need to turn it up, dont use live wallpapers and turn it to use 2g only, and then when you need the 3g turn that back on, there is widgets to get for that so its a one click as 3g really drains the battery, so when not in use go to 2g if your not surfing the web or wacthing videos off a site, doing those things will help the life of your battery.

That just means that your while your phone was turned on, 74 percent of the total power was used by your display.
Makes sense because you turned your screen on for about 74% of the time.

Try running fix permissions from clockwork. I recently got a boost in power & battery life from doing eugenes v6 mod and the suggested lag.

[Q] does the battery suppose to drain even in standby mode?

I am concerned about the battery life of my exchanged tab. The first tab I had has great battery life but had some sound issues that's why I replace it. But now I have this new tab but battery is draing fast even not using heavily. I am charging the tab whole night. I did not even has email account setup so its not retrieving any emails. Any suggestions to improve battery life please?

Is your wifi and GPS running at all times?
If you have rooted the tab try using an overclock tool to reduce the load, this should increase the battery life. Until then we are gonna have to wait for a custom honeycomb ROM that increases battery life. If its as bad as you say it is I would try another tablet and hope you dont get another thats messed up.
GL

No the tablet is not rooted but its factory unlocked. How do I know if the tablet is rooted?

It would only be rooted if you rooted it

Mine barely drains with screen off and Wifi on with everything syncing at the same time.. I can go like 2 days average use on my tab so far.

so it seems like there is an hardware issue. Diversion is your tab unlocked or locked?

Forever is an understatement.

I have different battery experience than the OP. I keep my wifi on constantly. On standby with little use (~0.5 hour today), the battery went from 100% to 93% since morning to midnight.

I think it's your unit. I use mine for about a total of 4 to 5 hours a day with wifi and bt at a fixed 75% brightness and when it goes into standby I only lose about 1% every 2 hours. Usually by the end of the day I'm at about 70% battery with a low of 50%.

Have you checked the battery usage to see if any apps are using a lot of battery? (Settings -> About Tablet -> Battery Use)
Mine was at 98% when I went to bed last night and at 94% about 7 hours later this morning. That's with wifi, bluetooth and GPS on, and GMail syncing (but not much else).

all of you guys whose battery has no issue do you guys have tab with locked or unlocked boot-loader. Mine is unlocked and i think because of that battery is discharging fast. Snoopstah i check the settings battery use is screen, browser (which is closed), wifi, android OS thats about it. Please let me know what should i do i have one more day to exchange it.
Thank you all

Exchange it. The battery life in standby mode is stellar. Mine's unlocked too and I lose 2% all night with everything on.

The bootloader on mine is unlocked, and came that way. In either case, that should not affect battery life, though I could imagine how rooting would possibly allow you to install or turn on something that would drain your battery faster (and is left off by default).
Just as an aside, what brightness setting do you guys use on your tabs? Somebody mentioned 75% and that seems super bright to me. I keep my brightness at around 20% or so. Auto brightness is way too dim on this thing. I look forward to some development action on this thing, the ability to customize the auto-brightness levels in CM7 on my Captivate is really awesome.

I have the same battery draining. I can only get 6 hours of straight usage with 20 on brightness. I'll exchange mine today. My zoom can last 8 hours straight of usage

I have no battery issue when in stand by mode and my tab is unlocked and the wifi policy is set to stay on. I drain about 3% per 7 hrs which is excellent.

quick battery drain

i was at 55% at about 5pm yesterday after 10+ hours of battery usage, 1.5hrs of screen, and probably 2 hours of LTE (the rest wifi). i use juice defender so when the screen is off it generally cuts data signals for me. well from 5pm to 9pm my battery went from 55% to 1% with maybe less than 30 minutes of usage (all on LTE though). i looked and no unwanted programs were running in the background.
i charged it overnight, got up and after an hour this morning of ALL standby (seriously the screen was on 3m), i went from 100% to 87%. that would mean on 100% standby the phone would have died within 8 hours, which is definitely not right or even similar to previous battery usage for me.
i restarted my phone, recharged, and so far it has been on for 40 minutes and the battery is at 99% with 2m of screen time, which makes a lot more sense. so have you ever experienced something like this where an android OS restart helps your battery, or does it sound like i might have a bad battery?

Install Carat, it will tell you exactly what is draining your battery. I'm guessing something something is syncing in the backgruond and killing your battery.

Lots of people are having an issue similar to this with ATT. Is your ATT?

i am in fact ATT. sorry i haven't seen the other posts about it, have they broken through to figure out the root of the problem? any link to a thread about this? it's very, very odd. 8 hours of battery life is no good, too.

I seem to get it when I am in a poor LTE coverage area, which includes one of my offices. It is strange. "Cell Standby" will usually have the largest battery usage in your settings. My temporary fix is to turn off "mobile data" from the toggle in notifications, especially if you have wifi where you are. You can usually tell when the battery is being drained b/c your phone will stay warm even with no apps running and the screen off. The only other thing that seems to help is restarting it every day or so. When I don't have this problem, the battery life on this phone is amazing, so I don't think it's a bad battery. If you find out a better solution, please let me know!

I'm assuming you get off work at 5 and use the phone more. If so, turn off juice defender when you leave work. Since juice defender turns off your signal, you have to reconnect every time you use the phone. That kills battery more than anything

I would agree with your deduction. Cell standby is a battery hog. I use Wifi when I am at work and home. and HSPA+ everywhere in between. (No LTE in NH)

Doesnt that defeat the purpose of having JD? Has anyone shown than JD uses more battery than not having it at all?
Fyi cell standby doesnt actually use as much battery as it reports, its just incorrectly displayed on the battery meter. Hopefully there will be an update to fix it eventually. Google it if you want to fix it manually.

Cell standby is just a reporting bug. It is not actually draining your phone as much as it shows.

There are two separate problems. There is the problem on the international S3's where it is reporting cell standby incorrectly. There is another problem with some of the ATT S3's where they are continually connecting or re-connecting to the network where they have a poor LTE signal. This is actually using the battery. You can feel the heat from your phone when you have no apps open and it is normally cool to the touch. The only solution I have found so far is to turn off mobile data, and the phone will cool down again and stop draining battery.

Right. It's just cosmetic.
I don't have LTE in my area and my battery life is okay. I use wifi at my house and at work. I just think it could be better, but i am used to my dinc with my custom rom and kernel. Amazing battery life. I can't wait until we get some sweet roms and kernels for the S3. So far i am super impressed with the phone.

i think you guys are right. the only thing that fixed my problem was restarting, which obviously also turned off/on the mobile data. how would you do that normally? just hit airplane mode and then turn it back on?
do you guys think this is a bug with AT&T that will be fixed?

This isn't a problem that too many people are having, but there are enough that it must be a bug, at least for ATT. There is a toggle in your notifications that will turn off mobile data. I don't think it is enough to just turn it off and back on. If you are in an area with bad reception, you have to leave it off or the draining continues. If you find something else that works, please share with us.

I'm also seeing this issue; battery gets hot and drains quick in sleep.
I'm running stock, and only rooted.
I do notice when checking my battery that "Android System" is taking up the majority of my battery, by a considerable amount. Is anyone else who is experiencing the drain issue also seeing this under their battery reporting menu?

Doze Performance

So Doze is supposed to minimize battery drain to almost nothing overnight or when the phone is not in use for a long time. How many people have actually experienced that? I'm not sure what to think, I lose about 1% per hour consistently overnight. That's without greenify or other battery saver methods. But it still seems excessive to me for such a hyped feature. I wonder if future hacks will be able to turn doze on in 1/2 hour instead of 1 hour. What have your experiences been?

1% per hour is pretty good. That means your phone would stay on for up to 100hrs which is more than 5 days. Are you complaining about that?

That is pretty bad if Doze is on given that 1%/hr is a widely accepted standard pre-marshmallow

Doze only dozes applications from waking up the phone at their will, but still does periodic wakes. It will only make a big difference really if you had a misbehaving app in the first place.
Don't forget that even in the best case that Doze stops all activity from apps, you are still using power connected to the cell and or Wi-Fi, plus power to refresh the memory and other peripheral chips, so 1% an hour could be considered quite good.
Try putting the phone into flight mode over night and see if that 1% drain an hour goes, if all is well you should get around 1 or 2% power loss in 8 hours.
The other think to note is apps can bypass Doze and schedule wakeups regardless, this needs an update to the app for Marshmellow. So if you had an app that wanted to wake the phone every 10 minutes to download the latest adverts, it will stop under Marshmellow when Doze kicks in, but they could update their app to use a different API call and go back to waking the device every 10 minutes bypassing Doze. I strongly suspect that the Google Play store will start recognizing this API call and may start warning about apps that are battery drains, so the user can make a better decision, otherwise Doze will have a short term benefit as apps work around it.

Phil

Doze is working really well for me. Battery drain overnight seems to almost be non existent. I went to bed with 51% battery life on my phone. I woke up roughly 7 hours later and it was still at 51%.

Yeah I had only 4% drain after 8 hours overnight.

that was a great explanation, also I do think 1% per hour is bad since like someone already stated that I've had phones that would drain about that without marshmallow. Also those other people who replied I would really like to know how you get such little battery drain, do you guys have a lot of apps installed? I unplugged today around 5 am and woke up around 10 am with 95%. I have about 60 apps and 3 email accounts (1 yahoo which is set to sync manually).
Personally I am trying to sort my battery issues with this phone as some are getting great battery life (5 hours sot with over 24 hours off charge) while others are barely hitting 3 hours like me. Also I would think doze would be better than what I am experiencing.

How long have you had the phone for? AFAIK it can take a few days for Doze to "learn" how to optimize (reduce) battery drain. You may find it gets better over the course of a week or so. If you check the "detailed" battery stats (click the first battery graph) you should see little to no "awake" time overnight when you'd expect Doze to kick in - e.g see this link as an example: https://drive.google.com/open?id=1wjguaIIcGgUZn7w-KXnY3MJ0qTK0rUCWiA
Otherwise try as @PhilipL suggested and run in aeroplane mode overnight.

Doze is working as advertised here. On my 5x and my N5 as well.

It could be your location and the cell signal you are receiving, sometimes even if you have a good signal you still might be evenly served by 2 or 3 masts and the phone keeps swapping between them, if you don't have too good a cell signal, the phone will be using more power during standby. The only way to tell for sure is to put the phone into flight mode overnight.
One thing to note, you will only get the maximum screen on time if you use your phone a lot, i.e. all the screen on time is used during a 12 hour day after a full charge. If you are only using say 30 minutes one day, 20 minutes the next and so on, your total on screen time achieved will be less than many are saying they get, this is because more power is spent over time on background tasks and syncing, leaving less for actual on screen time. My previous Nexus 5 for example, sometimes I would go 4 days without needing to charge it, but my actual on screen time was only an hour or so.
Perhaps crudely speaking, 1 day of very light usage may see enough battery power expended on back ground tasks to see 1 hour sacrificed of on screen time.
Usually it doesn't matter how many apps you have installed, that in itself doesn't use any battery, of course if those apps are constantly pinging back home to some server, then that is how power is used. Doze will be helping with those apps over night and other quiet periods.

Thats the thing I get about 2.5 hours sot in about 12-14 hours and have to recharge before the night is over. Of course quick charge helps but I really don't want to rely on something like that. Also I'm wondering if wifi calling on will help with battery or will it be like the iphone where it'll just drain more battery? Gonna have to play with it and see what I can improve on. Also noticed that chrome has been using about 15-25% battery on any given day. I do use it as my main browser but that still seems excessive so may try a different chrome iteration if it keeps up.
Thank you to everyone that has helped and hopefully this can be a come all thread for people with questions about or problems with Doze.

What brightness setting, as that can make quite a difference?

Adaptive brightness less than 50%

I'm getting 3 to 4% drain during 7 hours overnight, working well for me.

Hi
Did a test last night, charged the phone to 100%, put it into flight mode and went to bed, checked it this morning and still at 100%.

Now you need to find what is draining your battery overnight when not in Flight mode. I suspect you will find either Google Services or Google Play services not releasing the modem or something similar.

When I installed Cerebus it asked to turn off battery optimization. My guess is that is Doze could be wrong though. It was the only app that asked. So far battery life is better then the N6 that I had a Amplify running on.

That is pretty bad if Doze is on given that 1%/hr is a widely accepted standard pre-marshmallow

Might be a standard if everything worked perfectly, which I have yet to see. With this new architecture, you are guaranteed it. I love it.

I lost about 1% in 3 hours last night with WiFi calling on. Maybe it has to do with poor coverage. Last night I did end up with 3.5 hours sot which I think was my highest. So in the past few days I have factory reset and turned on WiFi calling.
Now I need to optimize my browser usage, chrome was talking more than screen was ~20%. Using #nochromo now and not much better.

Battery went from 66 to 64% last night in 8 hours.. #dozeisdope

Doze not what expected

When I got my N6P, I had expected standby time to be amazing thanks to Android Doze. My first day of use shows a lot of "awake" activity during the time when the phone is sitting on my bed side table, completely motionless.
Has anyone else had experience with their N6P doing the same? Am I doing something wrong that caused Doze to never activate?
As a frame of reference, when I went to bed the phone was at 47%. I took the screenshots when I woke up this morning.

Sorry if this is a silly question, but you have activated it haven't you?

Make sure it's on, and you've optimized all apps for battery savings. I lose 2% over night.

How do you know it's activated? The articles I've read say its automatic and you just need to leave the phone still.

I activated mine when my phone arrived. Settings>battery then use the battery menu and select battery optimisation.

Very frustrating reading replies that say Doze must somehow be turned on. It DOES NOT have to be turned on. It's interwoven into Marshmallow automatically.
You can tinker with battery optimizations within the phone's battery settings, but that's about it.
Note: If your phone needs to conduct maintenance (update apps over WiFi, etc.) doze may not kick in the way you think. If your phone has nothing to do and is sitting still for an extended period of time, it'll enter Doze and only sip battery.

You can try greenify beta it has aggressive doze when screen goes off, just whitelist the apps you need to notify you immediately.

Sorry, my bad. Battery optimisation is separate from doze then?

I'm seeing the same problem. 20% depleted in 7 hours overnight just sitting on my nightstand. Deep sleep in better battery stats showed 95%. Not sure what's going on.
How's your charging speed? It's nowhere close to what others are seeing. Even though it shows rapid charging, the amount of time to fully charge is high. 3 hours from 25%. 45 mins from 85% etc. Are you getting fast charging times? I can understand some process binging on my battery while running. I'm getting no more than 3 to 4 hours screen on time. But I don't understand why I would have slow charging times. But if you are also seeing slower charging time, then perhaps it could be.

That's just a feature that lets you decide what apps can override any kind of battery optimization

Lost 1% in 6 hrs last night,make sure all apps are optimised in doze setting

Looks like it could be Tasker. I'm going to uninstall it and see what happens.

Doze works great for me. For example, during the night, I only lose like 3 percent battery life. That's pretty freaking low. It's like I went to sleep at 75% and woke up at 72%. Very effective imo.

By the looks of it, doze should be on by default. Going into settings/battery/battery optimization-just shows which are optimized and which aren't. It's not an on/off thing.

The only apps I can't optimize is Android OS and dm service. What's dm service anyway

Unfortunately, that's done nothing. Lost 5% in 1 hour just sitting. BBS shows 76% in deep sleep. Screen on 1%. Awake (Screen off) 25%.

This was about 5 hours untouched on my table last night... Working fine...
The the thing I don't really like about doze is, it only works if the phone is flat on a table... Any type of movement, be it in pocket or even on the car dash, it won't come into play...

That horiztonal bar (a clear indication of Doze) just doesn't happen when leaving my phone overnight. The "awake" bars at the bottom of the battery screen in Settings is also switching on and off periodically when the phone should be dozing.
Does that mean a third-party app is the cause?

My guess is yes, some app is staying awake.
It would also explain slow charging....something is eating up CPU cycles and preventing the phone from idling down and sleeping.
It isnt just a 6P thing either....my LG G2 with numerous ROMs/kernels has occasionally experienced issues like this. Almost 100% of the time it could be traced to an app that was misbehaving. You can use a battery tracking app (GSM battery monitor, better battery stats, etc) to get more detailed info. If you arent rooted Im not sure how detailed the info can get, but its probably a lot better than the stock battery graph.
