[Q] Battery draining on idle almost 2% per hour with only WiFi on.

It easily looses 15% overnight. With everything turned off.
0 running apps, very few widgets, no BT, no sync, no GPS, auto brightness and even battery saving mode on. Only WIFI is on.
Somewhere Samsung has been promising like 800 hours of idle time. And with current pattern it is going to be 0% in approximately 50 hours without use.
BTW, with WIFI off, it is draining less but if I remember correct it was still at least 1% per hour, which would make it 100 hours. I noticed that battery chart shows Awake quite often, like every 5 minutes or so there is something, not much continuous deep sleep, maximum it was 1 hour of continuous deep sleep in the whole day.
Android OS tops the battery usage list with about 52% at the moment. The Android version 2.3.6. Baseband N7000XXKK5. Kernel 2.6.35.7-N7000XXKKA-CL726566. Build number GINGERBREAD.XXKKA.
I've been using it for a full week now. Could it be related to battery calibration?
What are your thoughts?

I installed JuiceDefender Plus and my battery life is improved. It's not significantly longer, but, I feel better as I can customized it.

Do you have background data enabled? And using the battery usage chart, what is using the most amount of power? The phone itself seems to use more power when the wifi is on consistently. Also, if you're using a rooted phone you might try apps like SetCPU or other CPU controlers to force the CPU to not run as high. Usually helps with increasing battery life.

Thanks for the tips. I have background data on (otherwise even Android Market is not opening).
Still I am not very happy with battery life. Especially idle battery life.
Last night I left it with Sync on and 100% battery. And look at the results:
Look at the screenshots, more than 50% gone in 8 hours. That's 6.5% of battery per hour on idle. And battery flat from 100% to 0% in less than 16 hours without even turning on the screen (with WiFi, Background data and Sync on and nothing else). This is not right.
Do you see similar results?
I am really hoping that ICS with its dual core support will resolve battery issue of Galaxy Note.

What is your wifi sleep policy set to? Try setting it to screen off. I really wonder if wifi can make such a huge difference. I hardly lose 2-3% during the night. I am using the abyssnote kernel now but im sure i didn't lose as much as you even when i was completely stock.
Also use cpuspy to see if your phone is going into deep sleep.
Sent from my GT-N7000 using XDA App

Go to a 2.6.35.14 based kernel to get rid of Android OS eating up all your CPU (its probably not going to deep sleep, check with cpu spy (how much time in deep sleep) and betterbatterystats (check whats using wakelocks) )
I'd install the FM kernel (or similar) and check with cpu spy and betterbatterystats.

Turning off background data (it is required for android market, but after your done downloading apps it can be turned off again) and wifi (for night or when not in use for long time) seems to help a lot.

Looking at those graphs its more of a end user issue than an andriod issue, wifi is enabled and running for the entire 8hrs and i esitmate about 5hrs that the phone is awake instead of sleep mode. which is probably caused by your app or settings.

I have Wi-Fi, GPS, background data and auto-sync on at all times. I lose 2 or 3% overnight (depending on how tired I am ). I do not run any sort of battery app.
So surely it can't be down to OP just having Wi-Fi and/or background data on?
Definitely it will be interesting for OP to switch both off and see what difference that makes.
The graph shows a very consistent drain so it's surely not down to anything intermittent.
OP are you using the original battery? I reckon it might be faulty...

Except it can't be the apps as the 97% OS shows...

Edanfalls, yes using original battery that came with the phone and which says made in Japan so should be solid .
Now after 3 weeks of use, I noticed an improvement of battery life overall, maybe it is that battery calibration that is happening still, slowly?
Now it does not loose so much overnight, last night for example with background data, wifi and even Skype on, it lost about 17%.
It is still draining much more than many people (including you) are reporting. I am suspecting that it is due to very old software (KKA build). I bought my note in Austria and they don't release updates for Austrian phones yet. German ones received already several updates since then and are reporting performance improvements. So this is likely what is affecting my Note's battery life. Will see how it will improve after finally software update comes, especially the ICS one.

I wouldn't think calibration would happen on its own unless the ROM was explicitly designed to run an auto script on reset (doubtful in your case).
I would read up on conditioning your battery and start with that, if you haven't done this already. Then, grab System Panel from market (paid, but well worth it) and use it to pinpoint the culprit(s). With the app, I can always find the offender, see battery usage over 2 hour / 8 hour / etc, and use its widget to *really* auto kill stuff ( by really I mean actually remove stuff out of memory gracefully, unlike many "app kilers"). Good luck.

Cell Standby has nothing to do with battery drain. That 46% is kind of measure to be 100%, so it's not the main problem. You should check it with some utility to help, such as BetterBatteryStats.

Got PowerMax on to help me get through the day
Update: It seems that my battery drains 1% every two hours with occasional time check and sms. Pretty good than stock Froyo.

its normal in almost GB 2.3.4 Versions... Battery is calibrated after some chargers!

experienced that too
these are my settings:
2G connection
GSM only
25% brightness
dark wallpaper
wifi-off
NO running apps on background
done with:
reflashing
battery calibration...still no luck
after sending 1-2 SMS, my battery consumes 1% already
any idea?

While I did not pay much attention to Zeus V1 battery drain I noticed good battery life with Zeus V2..Had 5% drain while idle for 13 hours and about 2 days with moderate to heavy usage...flashing stuff rebooting music and some wifi

Battery life in sleep mode?

I have had my Nexus 7 (16gig) for a week now, bought it at a local Sam's. Overall I love it. My one complaint is a big one:
The battery seems to drain as fast when the tablet is put to sleep and when it is in use with the screen at 100% !
I powered up the Nexus 7 at about 11am this morning and the battery was at 100% after a full nights charge. I used it to read for about an hour then shut the screen down. It was undisturbed until it about 10:30pm and the battery was completely dead would not even display the charging icon, let alone boot up for about 5 minutes after put on the charger?
Do I have a defective unit or is something not set right? It is still stock 4.1.1.
My Kindle Fire had amazing battery life when in sleep mode, like more than 24 hours.
Cen5

either defective or an app chewing it up.
My battery life is brilliant. I charged it up on Sat afternoon, took it off charger at 5pm. Didn't touch it again until 11am on Sunday morning -- 18 hours sleep -- and came back to it with 93% battery, This sleeps well, unlike my Xperia S

The only complaint I have about he nexus is also battery life, although nowhere nears as bad as the op, it's not even close to the iPad, which I can leave on standby for a week and come back to with plenty of life left, i'm lucky to get 3 days of standby on the nexus.

a lot depends on what you have syncing in the background and what settings you have. I don't use social media accounts much at all and as a result am not logged into them or syncing them. When I shut off the screen I have very little battery drain at all.

Saturday night, I had 54% battery life when I went to bed. The next day, morning , I had 53%. Went to work...left it at home, came back 5 hours later 49%. Used it for a ittle while Went to see the dark knight, came back, 44%.
Now its at 10% after a few hours a constant use.

set your N7's wifi policy to "OFF when Screen is Off". i bet a dollar it helps.

Sounds like an app or something is keeping the system awake. Check battery use settings. Has lots of useful information like keep awake time for different apps and stuff. Not perfect but gives an Idea.
I like to use the app "Batterysnap" so I get real time tracking for battery level, voltage, temp etc and I can view it in a nice graph.

Might want check out Google wallet, sounds dumb i know. My battery seemed to drain more in sleep one day, went into Google wallet (this was an issue on the nexus s early on). Even though i had already set it up the app acted like it was never opened, and would sit there trying setup for first time use and would hang at loading the tos.
Might be in my head, but the device drains at a respectable rate now

I had the same issue on my HTC HD2 running android, turned out it was an app that was running in the background keeping the GPS radio on and searching for a sat lock, disabled it and fixed the issue!

just check your battery stats and see what's keeping the CPU churning.

Mine was losing 1% per hour until I uninstalled facebook and turned off GPS.

I have FB and GPS on mine and only used about 2% overnight last night (about 8 hours).

I had mine on standby for nearly 12 hour and it only lost 1%. I had WiFi and gps turned off. I don't know if this is because I rooted it or not.

Had mine nearly full charge, went on vacation monday, came back saturday and the battery was 68%. Pretty impressive if you ask me.

I'd you aren't using NFC, try disabling that in settings as well.

Left mine at 99% last night. woke up to it at 98%. battery life is great for me

My battery isn't anything like the OP, but I am a little disappointed in the standby power use coming from a Nook Color running CM7. With just the wifi policy set to "off when the screen is off", it would lose about 2% per day. My Nexus 7 loses about 10% a day with me going in and disabling location services and wifi. That isn't awful but you know what's better than 10%? 2%. I thought the Tegra 3 companion core would actually keep the sleep power usage the same between the two devices.
Better Battery Stats shows that even in airplane mode (which grays out the NFC check so it should be off) NfcAdapterManagerImpl is waking the CPU, about a minute for every hour of sleep. If you don't use airplane mode, then the ConnectivityService uses power too (even if Wifi is off). Finally, if you don't disable all the location stuff NetworkLocationActiveCollector and the associate subservices such as CheckinsNotificationService also eat some battery.
By far the worst potential offender is com.google.android.apps.wallet.pin.PIN_EXPIRATION_SERVICE, which can hold a wakelock for hours at a time that drains the battery at two percent per hour.
Like I've said, the battery life isn't terrible (unless the google wallet service stays running), but it certainly could be better. Battery life while actually using the device is fantastic and I love it.

airplane mode...
i just power off when i know i wont be using within 10 hours.

It really has brilliant battery life. Syncing to G+, Gmail, Facebook

[Q] Poor battery life?

Hi, I bought my moto g 2014 2 days ago, I bought it because I briefly owned the 2013 version and I had great battery performance on that device.
Yesterday, I got only around 2.5 hours of on screen time, I installed titan rom and today I got 3.5 hours so it did improve, but in the battery thread most people are getting 5 hours of on screen time so I know it can perform better.
Do you think is because the battery is still calibrating?
I have good signal most of the time so I don't think that's the cause.

When i bought this phone i had similiar battery life at first time. I would recommend you to wait at least a week, 3-4 battery cycles. Now I'm getting about 4,5-5 hours SOT on my XT1068 too.

Well, that gives me hope, I was surprised by how bad the battery was.
Hopefully a few more charge cycles will make it better.

I easily get 5hrs sot on 3g... Acceptable

I get 4-5 hours with WiFi on and 50℅ brightness, good considering its the same battery as the G 2013.

You guys have lollipop? I heard that on lollipop the battery life is decreased.

Same here. on lollipop i get 3hours of SOT while on kitkat i got 5+ hours easily.

Well, I actually got lollipop because the battery on my first charge was TERRIBLE.
I got around 2.5 hours.
Is everyone in lollipop experiencing the same battery life as I am then?
Wasn't lollipop meant to use a new technology to save battery?
I use my speakers on max/almost max volume for about 30 minutes, of which maybe 10 are with the screen on.
Do you think that might be the reason?
It seems like a lot of battery consumption for 30 minutes of music though.

I installed the captured OTA zip 5.0.2 XT1068 when i had 69% battery remain.. After a day i have 3SOT and 25% remain. Looks promising. Will report after few days.

I can only get like 2-3 hours sot 3g browsing and I'm using greenify and my brightness is one from the lowest....

So far everything about lollipop seems to make me want to downgrade to KitKat.
Better performance & battery on KK as far as I have seen.

Anyone knows how to set "Contacts to display" on this phone?
I have gmail, also add hotmail and yahoo and all contacts are displayed even ones without phone#.
Very annoying.

Any help on fixing this appallingly terrible battery life? :/

With me it apparently was an issue with google play services and data.
I turned off background data but smartlock is not working now.
Today is my first day with that turned off, I'll see how the battery holds up, but so far it's performing way better than before.
My battery drains when there's no wifi around too. . .

I'm glad you figured out what was the problem. I forget to mention you the app BetterBatteryStats which can help you find out which apps are causing battery drain. Btw. now I can confirm that I'm getting the same battery life on 5.0.2 like I did on kitkat, around 5H of SoT maybe a little more.
I only made screenshot's today, so here is my battery performance for today:

How did you manage to achieve that battery life? Do you use a very low brightness setting? I'm using auto brightness. Could that be the cause?
The best I've achieved so far is almost 4 hours.

I always use auto brightness, but wifi was on only when the screen was on too or maybe a little bit longer + about an hour of listening to music with headphones). I think I have a little bit better battery life than on kitkat.
You can try factory reset or BetterBatteryStats to see which app causing the battery drain.

Looking good, just like kk

please help me fix the battery life on lollipop
Can someone please tell me how to fix battery life after upgrading to lollipop? I use to get 4 to 5 hrs of SOT on KK now its lucky to make it to 2hrs.

Try wipe the cache or factory reset!

I've had my Moto G (2014) for a week now and have gone through quite a few full battery cycles now. Still on kitkat 4.4.4. Rooted.
I am only able to get 9 hours of use daily with 2.5 - 3 hours of screen on time.
My brightness is set at 60%. I may listen to music about an hour a day while commuting. I don't really talk on my phone much, I mean really, I don't (10 minutes max on a talkative day). Between 20 - 50 SMS messages each day. about 1 hour in total of social media stuff a day.
I don't use GPS at all, I have it turned off. Wifi is on so I can use wifi at home and work.
Any ideas on getting my battery life up to around 12 hours a day?

Sudden battery drop

Ok, I know that maybe it's too early even to write something like that, but I would like to get your opinions/experience on this topic.
I have been using a brand new Huawei P20 Pro since the day before yesterday (Saturday). On that day, I unboxed the phone at around 5 pm (battery was 55%), and after installing the updates and everything, at 11:30 pm it was gone. I plugged it and charged overnight, then used it the next day from 10am to 11:30 pm, being quite happy about the battery usage (it was 40% yesterday evening). This morning I switched off the airplane mode at around 9, and suddenly started to notice that battery usage was different, like the phone was dropping 1% every 2 minutes just scrolling on Facebook or browsing online. At 4 pm, battery was 16%, and after 1 hour without using it, it was 4% and phone shut off.
As I told at the beginning, I know that it's probably too early to worry, but have you noticed anything similar on your devices?
Thanks!

Almost no problems here. I've had mine for around two weeks and so far its battery life has outperformed all my previous smartphones (various Samsung models).
I did say almost because there was one day about a week ago where battery was dropping a fair bit quicker than usual, though nothing nearly as dramatic as what you described. If I remember correctly a charge and a restart fixed it. I've had similar experiences with my past phones once in a while, so I'm guessing an app or the OS itself runs wild sometimes?
If your problem persists then you might have a faulty unit of course.

Thanks for your answer...
This is my latest battery usage. I charged the phone to 100% yesterday and unplugged it at around 8. Now it's at 5%. What worries me is the fact that this afternoon, while screen was on, battery dropped about 1% every 2-3 minutes...
Current SOT is 4h 33m. I mean, that's okay, but so far from the incredible results I've read on the Internet (people posting pictures of 6-7-8hrs of SOT). Stats don't seem to report anything unusual: most consumption comes from WhatsApp, then Telegram and Facebook.
Have you ever experienced something like that on your device? I read on another thread here on XDA that people noticed a better usage of battery after a week... Should I wait before worrying?
Thanks.

I haven't been keeping a close look on battery use until now, and I haven't done any screen on-time tests.
I just checked my current stats in the system battery screen and from the Ampere app (and I just installed AccuBattery now that I'm curious) and when I put on charge now I still had 64% battery left after almost 17 hours of use and three and half hours of screen time.
