My battery drains so fast...

I dont know what the deal with it. I downloaded juice defender and nothing has changed.
I unplugged it from charge today at 6.20am as of now (10.20am) I have %79 battery left. 5 mins (if that) web surfing on 3g, 10 txts and 3mins of voice...
This is just ridiculous. If I was a moderate user I will have no juice by 2pm
I dont get it??
I have cyanogen mod 5.0.7.1 with oc'ed kernel. Screen brightness is about %20-%25 and it times out in 1 min. It syncs every 2 hours.

Try Enom's official ROM. I get nearly twice the battery life on that than on cyanogen.

OC-ed kernel and looking for battery efficiency?

No need to be smart about it. My buddy has the same rom and with moderate usage he gets 24 hrs of battery life. And also, It down clocks to 245mhz when it is not in use.

Well, you've answered yourself - if the ROM is the same, you have 3 options: faulty battery, faulty HW, or different apps installed and one of them draining your battery.
You can test the battery by switching batteries with your buddy, and you can check the apps by doing Nandroid backup, wiping everything and monitoring the phone battery drain, possibly even comparing logs of switched off devices (yours and your buddy's). In case you'll keep seeing significant difference - there will be no other way but to assume your HW is faulty. In case your battery is ok and wiping helps - install apps one by one and monitor, to find the rogue one.

24 hours.... I cannot make it through an 8 hour work day.... sure I use the phone, but that is the point of it... I went to bed at 100% woke up at 94%... pretty big drop for sleep mode.... this screen and hardware, you will not get great battery life without tweaks, IMO.... (or just do not use it)

everytime i use cyanogen 507 i ALWAYS get poor battery life. i switch back to stock ROM and its better. i really dont know why that would be like that though...

psh i took a nap one night (maybe a 3 or 4 hour nap), left my battery at i would guess 20-30 percent and when i woke up, i wanted to check my tweets so i hit the home button, come to find out its dead O_O

I see 2.5-3.5%/hr here.. No Facebook or Twitter syncing, but Google cal/contat sync, K9 IMAP Push email, weather updating, some other misc stuff...
CLEARLY something is wrong... Have you guys run System Panel or something to monitor the processes running to make sure something isn't driving the CPU all the time or something?
Do your phones get warm? Mine stays ice cold if it's outside of my pocket at home or at my desk at work, 73ish degrees F/23 C.

What about when you first load a ROM and the setup wizard has a checkmark next to Data collection by Google? Could that be it?

You should check the "Other Usage" section of the Battery History (in Spare Parts). See if your phone is sleeping at all. If the awake time is 100%, then something is keeping it awake, so check the "Partial wake usage" to see which app is doing that.

going from 100% to 94% while you sleep overnight seems pretty normal to me. certainly doesnt seem "bad".
definitely use system panel to see what's using your CPU. in monitoring, history, plot, top apps.

I'm brand new to the nexus and android, I am not gonna lie....not sure what I am doing or how to tweak/take advantage of the software. Yet I unlocked and rooted anyway, lol. Any help or advice always appreciated.

well some of this is going to be common sense, but today I turned off 3g (use 2 g networks only), wifi and the gps, I turned off live wall paper and I turned my brightness from auto to 40% (which, you cannot even tell the difference... the phone is still well lit). I turned on wifi or 3g when I wanted to check something.... and then turned it off.... today was not a super busy day on the phone.. but at the end of the work day... I had 60% of my battery left.... it is usually around 10-15%... I got the ideas from this site

[Q] battery issues - 3 charges most days

Hi everyone,
I brought this wonderful phone (or atleast i thought wonderful) couple of weeks ago ( delivered on release date)
Now i expected the battery to be good as its 2300 mah but it the phone doesnt seem to last no way near as long as other claim i had an s3 before this htc one, 9 times outta 10 i only had to charge it once a day and never activated power saver mode,
On the htc one i constantly have power saver turn on and it just doesnt seem to be doing anything , i havnt changed my usage of my phone, if anything ive used it less,
For example the s3 lasted my full 8 hour shift with nothing running expcept the tunein radio app, the htc one only seems to last 4-5 hours with everything closed except the tune in radio app. Ive not changed networks so low signal shouldnt be causing the drain as there isnt a difference in signal levels,
So is there anything else i can do to stop bettery draining. Bluetooth, wifi, nfc, etc all turned off, screen on auto brightness ,
Sent from my htc one with just 26% battery left and i havnt even rrached 4 hours of my shift yet, left house at 9:45 with 100%

You probably have an app preventing the phone from sleeping. There are loads of tutorials on how to check for partial wake locks to fix this.

Try this or this to detect the wakelocks. For more info on wakelock, read this thread

Definitely sounds like you have an app which is preventing the phone from sleeping and you should be getting a pretty easy 1 day out the battery at the very least in moderate use.

How have you TuneIn setup.
As general when you press pause rather than stop, itt continues to record that station and is always active. Iif you go into the app settings and turn off 'autostop recording' which should be defaulted to 8 hours - turn this to never and try again to see if it improves. I've seen TuneIn eat battery life on other devices where ths happens (people thinkits stopped when its just paused and recording away in the background...

That's possible ^^^^, however if he was just to hit exit on the app it should stop the services. That and really want to be sure, swype it away in the multitasking section.
Can try Betterbatterystats in the play store as a lot of people rave about that.
Also make sure Google Now is disabled. It sucks battery life like no other. Awesome tool, however to much drain on the battery.

Would be great if you posted a picture of the battery use. You must have a wake lock.

Guaranteed that you have horrible wakelock issues. Rogue apps, bad settings, and anything in between could be the cause.

I can go to bed with the phone fully charged and, 8 hours later, wake it up to see it's still at 100% (mobile data, GPS, WiFi left active.)
Once I'm bored of constantly picking it up and playing with it (i.e. get back to standard usage patterns) I get the feeling it will likely run to 3 or more days between charges. Won't be this month though

The Same happens with my phone.
The battery is really good. It feels like it is the battery time of my Onex x3
gesendet von dem One and only

Well there are various reasons for this..Maybe an app that drains much battery not leaving cpu to sleep.You can download better battery stats and see the wakelocks and the cpu states that your cpu runs on.. You may also need a battery calibration.It will not increase the battery capacity of course but it will eliminate the faulty battery stats bin that tells the system the battery percentage.You may have for example 25% battery left and your device may show 2% or even close.
I assume that you do not have wifi always on, screen on for hours or using mobile data..The consumption of battery is huge.

how ? when u first got the phone ? did you turn it on or did you charge it?

Worth dialling *#*#3424#*#* and doing the battery test, although as everyone else has said it's more than likely an app.

I had a sgs2 over 2 years,rooted and optimized in battery usage, i was already happy. Now with the htc one it's a completely new experience....already now after a few days,with root but still no tweaks i get 60% left at 11pm!before the sgs2 was empty...can't wait
For fiture developement!!

Download Better Battery Stats, leave it for a day and then upload a screenshot of your wakelocks. My battery is easily lasting the day (ended at 11pm at 76% yesterday)

Same-ish problem.
Hey i'm having a similar problem,
I bought the HTC One (silver, 32Gb) A couple of days ago and the battery isn't even lasting a day with what I'd say as Medium/light usage. I do leave Mobile data on so i can get Skype/Facebook/line calls ect instantly, but i assumed that's normal.
I just left my phone alone for an hour with the screen off and it lost 4%, could this be a battery defect?
Are you telling me to get over a days usage, i have to leave mobile data turned off and only turn it on when i want to use Skype ect?
I saw a post above that one guys gets 3 days of usage with Mobile date, Wifi, etc all turned on. Is this the norm, or does he have a super hero battery?
I see the general consensus is to download "Better Battery Stats" and send pics of wakelocks, but Is there comparable app for free that will do the trick, as i don't have money currently on my English account.
Thanks to all those taking time out of their own lives to help others.

Gravitybox smart radio
Removed about all the bloatware I could find using titaniumbackup (including Google search,google plus, google now)
Disabled all auto-sync except for Gmail
Disabled x-reality
Disabled "scanning always available" (search for advanced wifi in settings)

If you just turn the phone on and watch videos for 10 hours, I'm sure you could do that. You can't look at reviews and think that their battery tests (which don't mimic real use) are gospel. I just had my first day with the Z3C with AT&T service. Long story short, I'm getting the same battery life on my Z3C that I had on my Razr Maxx HD. And that's with location reporting on and brightness at 75 or 80%. On my RMHD location reporting was off and brightness was around 50%. I took it off the charger at 6am, it's 8pm now and I'm at 63%. 2 hours SoT.
If this was my Moto X I'd be at 15% or less.

Yeah, I know that's where you got the 10 hours number from. However, typical "real life usage" doesn't mean having the screen on for 10 hours. For example, I listen to a lot of podcasts and music. If I didn't I could probably double my screen on time. Stuff runs in the background and uses power as well. Battery life isn't just screen on time.

did you have a SIM card inserted? I noticed they didn't have a SIM card in theirs. This may turn off the cellular antennas
The problem with these synthetic tests is its repeating the same thing over and over again. Things like caching start coming into play

They didnt have a sim in? Thats pretty much invalidates the 10 hours number for sure. Cell service always drains more battery than wifi.

He has the phone in ultra stamina mode. If you wanna turn your smartphone into a dumbphone and have it last a week go ahead. Im gonna get two days out of one charge. Probably around 4 or 5 hours SoT, along with 6 or 7 hours of listening to podcasts and/or music. 10 to 12 hours of actual usage over two days is pretty pimp in my book. Im plenty happy with that. Dont know what to tell you.

Battery life won't be consistent for the first couple of times
You'll be configuring the phone (installing new apps, blahblahblah, more CPU usage)
Try it out after a few days for your usage to settle down...

Well. I'm basing this off of the screenshot they posted (I don't even know what that screenshot is trying to show). They really didn't say in their article. You can see the "no SIM" icon at the top and they're on WiFi.
I doubt they ran the test with a SIM card and 4g/LTE, and then went through the trouble of taking the SIM out and enabling WiFi before taking the screenshot.
Regardless, the battery life is good enough for me. Best from a phone I've ever had.

Sony says you can get 1-2 days on a charge with no battery saving modes on, 3-4 days with stamina mode, and up to a week with ultra stamina mode. Dude is on day 6 in that screen shot, so draw your own conclusions there. Plus, like another poster said, he's not on 4G or HSPA. Of course he'll have crazy battery life. My old flip phones used to last 3-4 days easily as well.
Everyone is entitled to their own opinions. If you think that the battery in the Z3C sucks, fair enough. I, however, am more than happy with a phone that gets the same battery life as my Razr Maxx HD. The Z3C has brightness turned up higher, and EVERYTHING on (except bluetooth), whereas the RMHD didn't. After one full day and 5 hours of actual use (2 hours SoT and 3 hours of audio listening with Pocket Casts) I'm at exactly 50%. Didn't charge the phone overnight. Gonna use it like normal today, see if I can get 2 full days with no battery saving mode turned on, 10 hours actual use.

Well again, the guy doesn't have 4G or HSPA on and is on wifi. Those are not 'real world conditions'. Maybe he doesn't have 4G or HSPA where he lives, but I do and I'm gonna use it. Good for him. I like smartphones better than dumbphones though

That is the only difference I'm finding between his settings and mine but I'm doubtful it would double my screen on time.

What do you want, unlimited screen on time for 2 days no matter what? Thats now how batteries work.

Screen Brightness kills battery more than you'd think

So the poor battery life on my Note 4 might have more to do with screen brightness than I would have expected. Unfortunately, most people posting their SOT's aren't doing it in a very scientific way, so it's hard to know what we should expect from these devices.
Here are my battery test results using PCMark for Android https://play.google.com/store/apps/details?id=com.futuremark.pcmark.android.benchmark
In one test, I put the screen brightness to 100% and the results were pretty dismal. In the second test, I ran it at 50% brightness, which is brighter than the Note 2 at full and the results were much better.
I use Auto brightness during the day, which might explain my poor battery life, but I'd love to know what others score on PCMark are (it does run for 5+ hours!). I do keep my background BLACK, as well as using black themes on everything I can - for apps that only have white backgrounds, I use AutomateIt to invert the colors automatically. I would have thought these black backgrounds would do more, but it really comes down to brightness it seems.
I'm using an Exynos N910U model and left wifi connected while doing this test - 3 google accounts are synced on my device.

thanks for tests im using my exynos version on auto brightness and generally get 6 hours SOT. i saw on alot of people s stats and people who has problems generally has google play services on their battery usage list and it definetly shouldnt be at there... its probably about location reports to google every1 should disable it from location settings it doesnt break anything.

Yes, location can be an issue, but I think that impacts standby time more than SOT. Currently I've done the following to help with location-related issues:
- used lion tamer (soon to be called amplify) to slow down NLP wakelocks.
- set my location settings to powersave mode
- setup AutomateIt to turn on GPS when I'm in Google Maps (I'm usually plugged into the car outlet, so battery isn't a concern while navigating.
- Greenify stuff like Google search, Maps and several others.
I like and use Location Reporting, so disabling it outright isn't an option. My standby usage is very good at usually less than 1% an hour and my wakelocks keep my device awake usually less than 6%, but I'm still working to lower that number.

Before I started tweaking, I was getting around 6%-9% drain PER HOUR! Disabling stuff without root only got me so far, then the xposed tweaks and Titanium Backup had to be used.

like i said i dont know whats wrong for some people its probably something you installed(skype maybe) or mostly about location reporting. even last night i left my phone at 90% when i get it this morning after like 10 hours it was on 88% like i said earlier wifi was connected no power saving etc just normal idle time nothing special.

I was testing without any apps installed (just whatever I used to record battery consumption) and it was crazy high. Then I started adding accounts and apps, tweaking and I got my standby time to be much lower, but SOT leaves much to be desired. I'm going to try using the manual brightness and see if there are any differences - I often find auto brightness to be too bright or too dim! No "sweet spot" found! LOL

Greeny can also help but may need root

I'd suggest changing the settings for your Battery Monitor Widget app. AFAICS it polls every 10 minutes so a wakelock occurs every ten minutes to save the data. Use something like an hour and see what happens. Also would highly recommend BetterBatteryStats, a free version is available here for members.

I'll try that, although that might only improve wakelocks, not screen on time.
BBS never worked right for me. Always complaining that it couldn't retrieve the stats or falling back on something else.

I was getting around 6%-9% drain PER HOUR!

Wait, with the screen off? Then you have something horribly wrong with your device. Mine did a few % over a night. With nothing done to the phone to conserve battery at all. Snapdragon, though. With the update.

I loose only 2% for 7h of standby last night.

We are seeing a trend I think, I noticed that it's mainly us 910U users or exnyos users complaining about battery life. So it must be something in the 910U rom?

I've got a 910F and I get 6 hours screen on time maximum :/

Doesn't happen now that I've rooted and applied my standard tweaks, but I tried a factory reset to see if I could correct the high standby drain and was not successful without these tweaks.

I have 910f and i got same issues with my batt.
i've tried clean system, root, custom rom. Battery is always draining higher than some people.
As i said in other thread: some people have an issue, some have great battery life. And nobody knows why

Maybe it's the guys who keep it stock and don't root, custom rom and "tweak" that get the good battery life.

Delete it pls.

T700 Tab S Standby Time!

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!

Battery %bleed
Losing around 30% battery over night idle.
*wifi & sync on...

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.
