Usually charge my Tilt over night. But just to check it I unplug it before going to bed.
Started at 100% when I went to bed, I got up 7 hours later and it was at 56%. That is far worse than I expected!
Is this normal? Or shouls I restore it back the the original ROM and exchange it while I still have time.
What did you have turned on? If you leave Bluetooth and WiFi on overnight it'll definitely kill your battery... you should disable them in the commanger when not in use to save battery life.
Also, if you have the mail client set to check for new mail often (every 5 minutes or so) it'll keep firing up a data connection which uses the battery.
Thats certainly not normal. check if you dont have Wifi or an 3G connection at the moment.
I did have bluetooth on. I am on a 3G network, but not connected to a data session.
I had this problem with one of the 'cooked' roms. For the 5 weeks I had my phone, I never had a problem with it draining overnight. I flashed one of the roms, and two nights in a row I woke up to a dead battery. I reflashed the ATT rom, and haven't had a problem since.
Overnight battery drain
I have a tilt, std AT&T rom, with some modifications and updates, found here. I have pop email service running every 15 minutes, and commontime Mnotes push email to my lotus notes files and email, bluetooth on at all times. My overnight battery drain, 8-9 hours will be from 100% down to 89-92%, so I would say there is something else wrong. If you have "battery status" (found in this wiki) on your today screen, it will show you battery drain. You should also have the tweak settings to turn off your 3G connection after 1 minute after completion of data transfer. If this does not do it, go back to the OEM rom and then add your updates.
It should not drain the battery like you are seeing, my reference as a guide and I push my phone pretty hard for data and email.
Good luck,

Totally agree.
there is also the posibility that you have a defective battery that's not holding charge. If you check with your phone supplier and tell them nicely that's the problem they will most likely give you a replacement (as they will send the old one back in the packaging as a return).
OK, I'll flash back to my original AT&T ROM and see what that does. I have another batter (1650 from ebay, a cheap one) but don't expect to have it for another 4 or 5 days.
it's a shame because I really like this Dutty's ATT Beta 2.
Anyone have a good full featured ROM their using that I can try if I find the AT&T original give me better battery life?
My overnight drain with bluetooth On and band set on EDGE is 4%. The only times I've found it low to dead overnite is when I've left WiFi On, not sure why as it should standby when off, but at least twice it's sapped the battery dead.

I wonder if when you get below a certain crital % battery level that cellphone or any Tx/Rx connection drops off? I have noticed once before (and never associated it with anything) that when I was near an audio device (my PC speakers are best for this) and my battery was low that it was 'polling' the cell network like crazy as if losing connection! This may also work for WiFi (which in sleep periodically checks if the network is still in range) and BT?
Something to investigate!
Overnight, around 7hrs, from a 100% battery with BT always on Wi-Fi off, 3G always connected and it's setup to check my email every 2hrs, I only loose 1 to 2% battery life and my alarm going off for about 5mins , this is with the Orange HTC Tytn 2 using their original ROM
Wel, I flashed the latest Dutty's ATT touch ROM. My battery did improve.
From 100% to 78% over night with bluetooth on. Not great but much better.
I'll see how it goes tonight.
My overnight drain is typically 5-7%.
This is with e-mail poll every 5 minutes, so data connection is on.
Bluetooth & WiFi off.
OK, checked it again this morning and this time at was at 98%!
I couldnet figure out why the day before it was at 78% and today at 97%. everything was the same (or so I thought).
I noticed later that the Radio pluging (to toggle BT, WiFi, and phone radios on/off) was not on my today screen. It was set to, but apparently didn't load. Maybe that is somehow the issue. I'll keep it off all day and see it I don't have more juice at the end of the day than usual. I'll turn it on again for tomorrow and see my my battery drains quickly again.
I think the battery capabilities may have a lot to do with this.
Anyone here use Li-Polimer for anything else? I do, minature 3D (no pun intended!) RC helicopters, and the individual packs NEVER produce the same charge/discharge cycle..
Not one is the same from purchase.
Some packs can devolve a low current without much adverse effect, others can charge with a greater sustain. If you present a charge cycle whilst discharge is taking place, it can effect performance.
Lots to look at here guys including device settings but when you put all these aspects together, as in this thread, there is something to work on...
I could've swore that when you turn your phone on stand-by (press the power button on the side to turn the screen off) that it also disables wifi until you wake the phone up.
I was having this same issue. Turned off Bluetooth and Wi-fi at night, hit the power button on the phone and now it only drains about 3% in the 6 hours I sleep.

It does unless the ROM you install changes the registry keys or you do yourself.
ah, okay.. well as long as the battery life lasts longer than the tytns then i'm happy
don't forget the default design of WM !!! ( X does not closes running programs ) ... get a task manager and make sure X DOES fully exit
I had to add that in to cover all the bases
my phone is almost constatly awake (as shown in the battery use graph of 2.3.3).
is there any way to see what causes that? aside from spare parts battery history which says its android system.
any tips?
another poster had this issue and it looked like his phone would lose a signal/service, then re-acquire it, and from that point forward the phone stayed awake and did not go back to sleep. check to see if you have red signal area showing lost connection, and if that correlates to when your phone started staying awake the whole time...
also, check your wifi sleep policy. Settings->Wireless&Networks->Wifi settings->[press menu]->Advanced->wifi sleep policy. should be set to "never" anything else would drain my battery faster. there is some bug in gingerbread. i tried this and it helped me. see if it works for you.
oh yeah forgot to say remember to turn off your wifi when not in use
checked for signal loss ... nothing there
also wifi was never on so the policy can't be the culprit ...

That would be me The signal loss was deliberate though, I forced 2G only at that point, but yeah it stayed awake afterwards.
I've also had random extended awake periods in the night that weren't related to any signal loss, I'll have to remember to get a screen shot next time it happens.

I have the exact same issue. Help?? My phone is always in the 'awake' state regardless of what I do.
i'm using CM7 and one possible source of the problem is the trackball notifications. as long as the light is blinking the phone is in a wake state.
there must be other issues tho, as my phone keeps awake sometimes without any notification blinking.
Notifications keep phone awake.
I'm having the same trouble with my Nexus One on CM7. Any time I receive a notification, the trackball starts blinking and my phone stays awake until they are manually dealt with. I like the blinking light, but it would be better if it only went for a couple minutes or so and let my phone go back to bed...
Does anyone have any advice for this? I've tried CM7 stable and now the current nightlies, and it's all been the same.
Thanks!
Hey guys --
I did a search and while there is much discussion of deep sleep problems, there is no clear way I could easily find to identify the cause.
I have CM7.20, the MiRaGe latest build on my NC, with the settings listed in my thread (see the sig). Recently I noticed that it is not entering into deep sleep, indicated by losing ~20% battery while it is asleep overnight in about 8 hrs. Battery results tell me it's "WiFi" taking like 30% of the battery, which seems quite odd, since I had it set to turn off WiFi while the screen off unless connected to the charger.
Any clues on how to identify the problem with deep sleep?
As for usage, I am using my NC 99% of the time with the following apps:
Moon+ Reader (probably 70% of time)
YouVersion Bible app (most of the rest of the time)
Dolphin Browser HD (maybe 2% of the time)
Enhanced Email and MailDroid - very occasionally but they are checking mail on 15 min intervals when wifi is on.
I have a ton of other apps installed but I almost never use them except for these.
Any help on how to determine what is causing the NC to not go into deep sleep will be immensely helpful. I have a 2-week Euro business trip coming up next month and I would really like to solve this before then.
Thanks!
Better Battery Stats might help. Try turning off sync before bed and see if you still lose 20%. If so, it's definitely some app that's the culprit. Grab something that will tell you what program is using data and how much/how often and you should be able to isolate it pretty quick.

OK, but it should be turning off wifi, and therefore sync for ALL apps, when it is asleep. Can an app override this setting? That's my guess, is some app is doing this. How can I ID that?

Like envygreen said use that app to track wakelocks. Even if wifi is off, some app may be applying a wakelock to try to sync.

Alright, I'm on it
So last night I finished charging it and read for a couple of minutes, then put it to sleep to see how it went overnight.
My Wi-Fi sleep policy is set to turn off wifi when the display is off.
When I got up this morning I checked it and it had lost over 10% battery over night, and I checked BetterBatteryStats and I think it is going into deep sleep but maybe not shutting off wifi.
I have attached the screenshots from BetterBatteryStats, and I think I need help interpreting them and finding the cause.
ok, so here I am replying to my own thread... If I am reading this right it seems to be looking like my wifi is on the entire time, not only when the screen is on. Is this the right way to read this? In this case, it looks like "Wi-Fi sleep policy" being set to "When screen turns off" is not actually working... right?

It sure looks that way to me too. It says wifi on 8 hours. Did you try toggling the setting a few times? Also you are on Mirage and he may have done something in his tinkering that messed that setting up.

yeah I did toggle the setting on and off, and in fact before I had it set to "On during sleep if plugged" for a long time, recently changed it, thinking maybe this was the cause.
But it does appear that maybe this is what is killing the battery. There doesn't appear to be any network activity when the screen is off, just looks like the wifi radio is powered up.
Any advice?

Hmm. that seems like an extreme step, but maybe ... wonder how much of the snappiness I will lose.
EDIT: OK I switched to CM7.2 stable. Nice I didn't seem to lose any settings. Let's see how it goes. Thanks for the advice, I'll report back here if it still does the same thing.
Also uninstalled beautiful widgets... figured maybe that could be causing an issue.
Oh, and I probably had a SOD kernel patch applied... perhaps that was the problem too
guess I should change only one variable at a time for a good test, but in reality I just want to get it fixed and not really diagnose it.
I was having a similar problem...what I did was run the V6 supercharger script, granted i am running CM9 atm but it took care of any problems I had with battery life and wifi signal.
Question: does having WiFi on keep the phone from going into deep sleep at all?
I have found that my phone is not going into deep sleep. I checked what is holding wake locks, and the time with wake locks is way less than the time the phone has the screen off, so it appears it is not deep sleeping, even though there are not wake locks.
I have an extended battery, so I get good battery life, but always interested in improving it. But I also have this thought that if I have to turn everything off, and only synch when I turn the screen on, that is not ideal either.

Get CpuSpy free on play store. It will tell you exactly how much deep sleep you are getting.
Having wifi on all the time should not prevent deep sleep. Only when things use it does it come out of deep sleep.

I have CPUSpy Free, and that is how I know I am not getting deep sleep. My challenge now is to identify why.
OK, so it seems that CM7.20 stable definitely fixes things. I didn't flash the SOD fix, so maybe the SOD fix was preventing deep sleep before, or maybe something else in the kang build was preventing deep sleep with wifi on when the screen is on.
However the better battery stats still seems to say my wifi is never actually going off. I am not sure I am interpreting the results correctly. It looks like the wifi is on all the time even though it's set to turn off when the screen is off. But I can let the NC sit on my night stand overnight and lose only a couple of % where it was like 10+% before. I still think my problem was due to some app that updated and not the ROM because the problem started weeks after I last updated the ROM.
Hey I have just bought HTC One 2 days ago. Compared to my old Sensation XE battery life completly sucks. I usually use phone without battery saver, on auto brightness and with Wi-Fi/3g turned on only on demand. Today 8 hours after unplugging phone from the charger I only have 26%. Screen was turned on for 2 hours and 45 minutes only and Wi-Fi worked for 3 hours and 46 mins. I might also say that I did not charge my One before usage to 100% as HTC advised. Was that very crucial? Do you think that phone might be broken or I should just give him time to settle baterry better.
That's sounds like what I get. I turn off mobile data when using WiFi and vice versa. I always use power saver unless I'm 3D gaming. Which is only on the weekends.
I've had mine for 3 months now.
I've seen people get 7:00 screen time on stock unrooted.
I think my battery's broken too. I can barely reach 3 hours of screen time. With 2 hours I get like 11 maybe 12 hours of on time. Something's wrong with our phones...
Does anyone have any suggestions?

Your battery stats seem on par with me and the OP. Seems that only a select few phones get decent battery life.
My kernel (android os) has been in the 25-35% range,it has never been that high before.
battery life lousy
I get pretty horrible drain too. I charged it to nearly full around 7:30 last night. I took about 2 minutes of video, sent one text, and checked my email 3 times. After that I went to sleep and the phone sat idle. At 6:30 this morning, I'm down to 9%.

Wow, that's real bad.. When my phone is off during night maybe 7% is gone. Then again I'm rooted and use greenify aswell as battery doctor if that has any affect.
On screen time seems like my battery drains pretty fast too though. After 2 hours of music and surfing and watching videos I guess atleast 40% would be gone.
My battery life became horrible, too. My phones loses 4% per unused hour. No App seems to be responsible for that drain. Flightmode or powersaving mode ain't making a difference. I hope we'll find a solution for our drain.

@Racingmatt your power management services is on for quite a bit. do you have alarms.? i would bet that you either that maps location enabled or something of the sort. cause you also have NLPcollector on for around 40 minutes which is a bit much. also i would turn off GPS if your not actively using it.
@Rachorid how are you setting up your wifi? is it set to always be on? or set to turn off when screen off? you have alot of wifi wake. might be due to that. i know when i'm at home my wifi actively pings all devices connected which will force wake up my phone. yea its a bit annoying but i live with it. otherwise i just keep my phone plugged in.
if you both can get some SS of alarms i can give you a better idea. and when you SS the alarms make sure to click on the ones with the most wake lock so i can see the secondary screen that shows what the actual wakelock command is happening.

Here are the latest stats. As you can see many Google wakes.. removing Maps/Now/GMail/turning of Location (a few days ago) had no impact on my drain. The 2nd app on Partial Wakelocks was used actively.
I also disabled Wifi for about 2 hours.. no impact, too. Flightmode also had no impact (a few days ago).

The reason I didnt give you a alarm ss is because I didn't have any alarms when I went to the alarms section. I also had all locations services including GPS enabled but I just now disabled GPS but left network location enabled I'll give you a screenshot later so you can see the differences
I know exactly how you feel that's what happened to me,u was expecting so much from the battery and it turned out to be the worst..give ya some advice...3g drains the **** out of the battery ,so always jeep it off and turn it on only when you wanna use it...that way the battery will be acceptable...

I had awesome battery life a month ago with Wifi always on, auto. brightness and every app on hourly sync. (I have my phone since 7th of march) Sometimes I didn't lost a percent over night (8 hours) and I just don't know what it could be because I didn't install another app and no app seems to be responsible for that stanby drain. My on-screen battery life is still good. It also doesn't matter which ROM or kernel I'm using.
Here is my latest stats after 12 hours with 5 minutes of GPS use (turned off when not using)and network location on all the time with 3g/4g on all the time(turns off after a period of inactivity) . I can't give you a alarm stat because I'm not rooted.
Lithium-Ion batteries used in today's smartphones need atleast 10 cycles to show optimum power
so hold on until 2 weeks then you will get the full performance
i get 2 days of battery on my HTC One (since i dont have internet on my Simcard)
its 2G connection and auto Brightness and switched bloatwares off
i use Android Revolution HD 12.2

with normal use 3.6%/h is pretty reasonable. how much screen on time was that including?
My Tablet lasts 2 days before its totally dead with ZERO USE!
Updated to 5.0.2 as i hoped this would fix it. No change
Lost 10% battery while in power saver mode in a few hours!
Lags all over the place when scrolling, the play store is horrible when scrolling apps.
Right now my S6 has better standby on 4G and more life in use than my tablet has with no use!
Any ideas?
Can't speak for Lollipop, since staying with 4.4.2 and disabled auto updates. I only lose 2% in ten hours and the best Android tablet I have owned- especially in regards to low sleep bleed.
clearly something is not right have you factory reset it? That would be the first thing to make sure no apps are doing anything weird.
I flashed a whole new OS... should i wipe it?
You need to install a wake-lock checker, it will show how much time your tablet is actually in deep sleep mode, which uses the least amount of power, mine shows 97% time in deep sleep.
Some application can keep you tablet from going to sleep, alarm clock and sync can also, and apps/software you downloaded.
Do you get still get major battery drain after a reset, dont install any software/apps and the charge to 100% and then leve it for a few hours and then check how much power you have lost.
John.
Over an 8 hour period (avg) with wifi on, my screen brightness set to 10-20 range (that is the brightness I prefer on my tab s), and with greenify I lose maybe 1-2% battery. You definitely have some program or service constantly running or waking up your tablet, and due to the interactive governor that samsung uses your tablet wakes up at 1.9GHz each time to be more responsive/save battery by handling what ever is needed as fast as possible so it can sleep again. Unfortunatly if some app keeps going "hey, hey, I am here, I need you tablet, hey, hey, ect........." that battery saving governor will murder your battery.
So i wiped and its still 48 hour batter!

Do you need to have your wifi and sync on for business or something, if not turn them off, of use an app to to mange them like the free juice defender ect.
Just install it, make sure it is enabled and then make sure the icon is on your taskbar so it has not been killed, and them forget about it for a week and see how it goes.

for some reason on this tablet, wifi murders battery in standby. if you turn it off it lasts much better... but this tablet and this tablet only, leaving wifi on kills it horribly. but problem is, when you wake it for teh first time in hours and wifi activates, all of a sudden everything syncs and it's so damn laggy those first few minutes of use. it sucks. only this tablet. never had this issue with my nexus 7. that thing gave me 7 days stand-by time.

Try putting your tablet in airplane more overnight and see how much power it consumes. I lose 3% over 8 hours when I put it on airplane mode and disable wifi.
Im sorry but this is BS.
Its clearly faulty. its going to samsung. i demand a refund.
How much power wifi uses depends on the distance to the router and how much interference it has to try and break though to get a good connection which means using more power, that is why wifi uses more battery power on some peoples tablets than others do.
John.
disregard.. just realized my screen shots were messed up. I'll post my standby time tomorrow.
Here is a very simple stock no root mini guide to getting 1-5% loss over an 8-10 hour period while sleeping or at least while the tablet is asleep.
1. Install greenify even if you are not rooted and even if you do that have the donor package there are many many apps that do not like to sleep, greenify will fix that for you.
2. Unless you are a Doctor, CEO, or someone whose very life hangs on getting the latest cute cat post while you are asleep try to adjust your sync times from under an hour to as high as you can. (If you are turning off wifi then it might still matter if the app wakes up your device just to see it can't sync)
3. Samsung has given you a very nice QHD screen. It is high resolution, Amoled, and other nice rhings but while you sleep you can not see it so turn the brightness down before you touch the power button to 5-15. If you wake up in a dark room and need to use your tablet that level of brightness is far kinder to your eyes and even kinder to your battery.
Just doing this generally kept my battery usage down to only 2-4% per night, of course then I rooted my tablet and installed TW detox 3.0 and now it is closer to 1-2% per night. Try any or all of these and I hope it works out.

losing 48% per day... screen brightness wont help will it when screen is off all day
Screen brightness is for those times that an app wakes up the tablet and turns on the screen to tell you something (new email, facebook wall post, new cat video, ect....) and yes it helps.
If you are losing 48% a day then you have some app doing something that is keeping your tablet awake for a good portion of the day. Or you have a defective battery/tablet. I can surf the web for a good portion of the day and maybe lose 48%.

Are you rooted. It's sounds like you have some wakelocks? If rooted you should use greenify and a wakelock alarm to fix the problem.
i'm curious to see what apps and how many you have installed. Can you post screen shots of your app drawer?

what email apps and cat video watching apps are you using that turn the screen on? no app that I have EVER turns my screen on at all. the only app that does that is on my phone, and it's from textra, an sms app that isn't on my tablet.
