Battery sleep

I'm having an issue with my battery lasting barely 12 hours on just calls. I did the #*#*4636 etc.. and under "since last unplugged " it says 34 percent and when I click on it it says time spent without sleeping is 3 hours and 33 minutes. What other info do you guys need I will oblige. Thank you for the help much appreciated .. cm 6.1.0

Anyone please? My phone died yesterday while I was stuck in the snow and needed help. (NYC)
And I was stranded for 3 hours so any solutions would be helpful. Thank u and happy new year

I don't know what your problem is, probably something is draining your battery madly! I would suggest installing juiceplotter from the market, and then downloading super power v0.75 BETA. With juice plotter you can see what state your phone has been in (screen on, aon, wifi,...) and super power lets you very effectively control what your phone is doing. These are the two apps i use to substantially increase my battery life! Hope some of that makes sense and helps..

Thank you I will definitely try it out. Will it tell me what's using the battery?
Sent from my Nexus One using XDA App

You can easily see what is using your battery. Go to 'settings', then 'about phone', then 'battery use'. What does is say there?
I have seen a lot of people complaining about battery life when using CM. Not sure if that is a coincidence or not... Maybe do a Nandroid and try the stock ROM for a while to rule out a ROM issue?

It will show you if your screen/apn/wifi was on our not. Also if you charged your phone. You will have to play with it for a while till you understand which color indicates what but after that you can analyze what your phone is found doing on one sight! Complemented with super powers functionality it gives you a couple od great role tools to adage some good battery!

So it's lasted 12 hours, using the screen for an hour and 17 minutes worth of voice calls... I guess that doesn't really seem right to me, although maybe if the screen is 100% brightness... Maybe turn it down to 50% and screen time out to 30 seconds?
Have you always had this kinda battery life?
Can you try these things? :
type in *#*#4363#*#* in your dialer. Select battery information. Is battery health good?
type in *#*#4363#*#* in your dialer. Select battery history. first drop down select partial wake usage. Is anything look out of place (something much larger than the rest)?
Maybe download a program called traffic stats lite? This program will tell you which apps have been transmitting data and how much. Possibly a rogue app that is transmitting all the time?

Hi tech338. The battery health is good and I hardly ever have my screen on 100 percent bright. The battery was definitely better. On the partial wake lock the only thing with the highest bar is android system. The blue bar is half way up. And its at 1 hour and 17 mins
Thank you

It's a been a problem with almost all smartphones not just android. The only solution I've found and most reliable is to have a spare battery.

You can try my battery app linked in my sig. It pulls the info from inside your battery chip to re calibrate it.

[Q] What to do Against battery drain?

I now have one week to the Nexus One bought secondhand. It suits me perfectly stand alone I have a little trouble with the battery life of the phone. Morning when the phone is 100% and I come out of school (14:30 hours) the battery is still around 20%. I find this a bit short. Ok, I'll use him at school (bit Internet, twitter refreshes every 9 minutes)
There is an automatic task killer, and that helps a bit but I think there are about 80% after 8 hours battery life is a bit much. Me internet is also constantly and I really like to keep.
The battery is probably not because I've got 2 batteries and they both give the same result.
Anyone have any idea what I can do?
I've been a bit inet searched but not really found anything. I did see somewhere a separate battery behind the phone, but I'm not waiting because that makes him a bit heavier and uglier.

10% per hour is pretty poor battery life. Are you running stock Android? 3rd party firmwares can give you much better battery life (the latest versions of CyanogenMod are using less than 1% per hour when fully idle).
But there are things you can check. Have you looked in Settings -> About phone -> Battery usage? If you are using Gingerbread and you look at the graph, if there is a solid line (or mostly solid) next to the "awake" portion, it means that your phone isn't properly entering its low powered state. Download spare parts from the market and check out partial wake usage under the battery history section of that app.

Please post your screen on time value from the battery menu so we can see how long your screen is on.

I would say to go and disable background data. Disabling this will definitely improve your battery life. Of course, you aren't going to get you twitter updates but aside from that, the battery life should improve.

While it is true that battery life would improve if Background Data was disabled (or limited via a program like Juice Defender), it doesn't take into account his actual problem. Unless it is a ton of apps constantly downloading that is keeping his battery usage in the toilet, this will only yield a slight improvement. I believe the cause is is an app (or apps) that prevent his phone from entering the low powered sleep state.
I don't know what stock Android gets from completely idle use (haven't run it since July last year), but a basic CyanogenMod install would sip between 1-2% per hour with the latest stable and the latest nightlies, some are reporting 1% every 2-3 hours when the phone is left alone (due to a fix that lets the microphones go into a deep sleep state).

Twitter refreshing every 9 minutes can not be helping, that said I doubt that's your entire issue but reducing the refresh rate should help quite a bit.

If you bought it used, it could be a bum battery. Not sure i know what apps work best to find out that info. Anybody?

The battery app in my sig is the only one that reads the chip inside your battery to tell if it's legit or not, what the battery age is, etc. Needs root to work though.

You can also get Battery Left from the Marketplace and when it gets calibrated it gives you a time until death number and some other features.

for example, mine never last over 24hr even i turn off everything, use only 2G, with no app installed.
and it's instable, sometimes it drains so fast, sometimes not. I don't know why.

Until we get a software update probably will be great battery like the update for one x

I think that is why many of us expect a huge battery improvement after updating to JB ,perhaps the newer system wont be so power hungry.

these screenshots are fun and all but they are totaly irrelevant.
hoe much USE time are people gettng is whats interesting.
so screen on time.
as the goal is no drain with screen off and as long as possible screen on time (this is when you use apps and so on).
my phone can be on for 2 days and still hve 95% juice left but thats kinda irrelevant if i dont touch it.
when i use it non stop my use time averages on 4 hours and 15 minutes so far.
all the people having problems with battery drain must have either bad apps installed of verry poor wifi/3g connections.
as in a good serup with no bad apps and good signal wifi should not drain battery at all if your not using it.
i would so like all people with issue to lend me there phones for 3 days to see if in my stable envourement they have the same issues.
im fairly sure that all these problems are signal and user related and that it has nothing to do with the hardware.

My phone would only give me 2 hours max if the mobile data is on with sync off facebook sync set to 1 hour and hotmail sync set to 1 hours. But if wifi is on throughout the day i would get around 3 hours 15 min average with sync on hotmail set to push and facebook sync set to 1 hour. The battery is really poor as i only use it generally for txting whatsapp and just a bit browsing thats all nothing else. When i watch videos my phone consumes less battery, than normal usage which i do everyday. The highest screen time i have ever got was 4 hours 15 mins thatd because i watched a video for almost like 3 hours thats why. But the battery is still really poor

My android system also consumes a lot of power, its always on top no matter what. I am running on V_10H I disabled some stock apps using titanium backup and used fast demorcacy but the only difference I could see was android wakeups had been much lower thats all and so less power consumption when phone on standby thats all.

this is totally relevant information for regular users.
many people complain about battery drain and that a custom rom is the cause or custom kernel when its available, but what shows that it is not, is when you can place your handheld mobile or tablet alone with wifi set to instant off and you got 3g disabled and it lives for days without loss of battery, you know that it is stable.
when you suddenly lose battery in hours and previous tests showed it was lasting days, you can be sure you got battery infected apps trying to activate your cpu all the time.

i'd like to buy this phone but i'm a bit afaid of the battery drain. people who says it last 2 days with normal use other says that with gaming and browsing lasts 10-15h but a lot says that the battery lasts just 6 h with normal use... can someone who owns this phone and he use it with a middle-intense use (texting,browsing,gaming some time) tell me how much lasts the battery please??

Well, my usage pattern is kinda light, but still...
- took it off the charger at 7:15 am
- 3g data permanently on while I'm not at home (from 7:20 til 18:00 or 19:00)
- wifi on when I'm at home (during the night too, I never switch the phone off)
- sync always on (gmail, whatsapp)
- received a couple short phone calls, let's say 5-6 mins
- received a bunch of emails, say about 15 or something
- some messaging (on whatsapp and gtalk, I don't use sms)
- some facebook, let's say 15 minutes (through mobile website 'cause FB app sucks big time, always had and most probably always will)
- some net browsing looking for a few stuff, let's say 5-10 minutes
- checked a couple forums on tapatalk a couple times
- updated 3 or 4 apps on wifi
- downloaded a 50mb game on wifi and played it for like 10-15 minutes
- ebook reading on moon+ for 1 hour and 30 minutes (maybe even longer, didn't check the exact time)
I connected it to the charger when it reached 12% battery at about midnight THE NEXT DAY (yes, that is around 41 hours without recharging it)
Overall, I can say I'm satisfied, at least for my standard usage...
- Stock v10h firmware, no root (yet).
- Nova launcher since 5 minutes after buying it
- I usually keep brightness quite low unless I'm out in the open under the sun, good thing about this phone's screen is that it's usually very well visible even with only a 20% brightness. If I need to use it in full sunlight, I conveniently placed a full brightness widget on my homescreen, and then back to 20% with one click when I'm done. No autobrightness 'cause I don't like much how it's set to work on this phone (was kinda better on my old i9000, but oh well, 1 click widget and I'm good to go, no sweat)
- Disabled 3 or 4 stock apps (through app settings, no titanium or other stuff)
I noticed that battery usage was kinda higher before disabling those stock apps, I guess one of them was a powermonster of sorts (I suspect the meteo one, but I'm not sure)
- No facebook notifications of course, not for battery-related reasons but just 'cause I simply hate them... but I guess that's nice on the battery too

Impressive battery life

Guys is your battery life like mine? I'm impressed
Please note I disabled nfc and location services.

Must admit I found a huge leap in battery life by disabling location services.
For instance Facebook app instantly tries to find a GPS signal even if it's disabled in the apps settings. GPS just gets overly used in my opinion by a lot of apps.
I feel I lose too much functionality by disabling GPS with things such as Google Now so I keep mine on.
Still I find on the whole the Nexus 4 battery life is at least on par with the iPhone 5 in terms of my average daily activity.

you may also enable developer options then disable the animations ^_^

One of many things that the Facebook app does poorly. Why does it want my location when I open the app. At least 50% of the time, I'm only looking at my news feed. If I want to post my location or check in, look for the location at that point. At the very least give me an option in the settings to turn this off!
I find battery life pretty good even with location services on. It'll go a full day without problems which is all I expect of a modern smartphone. I can do the things I want and unless I play a lot of games one day, I won't need to charge until night time.

Please use the battery impression thread. Finding it will be an exercise left to the OP

the battery life

What really is up with Android phone and their battery life. This been bugging me for like forever and its 4:00 AM and i have to post.
Like my sister had s7 edge and just the general messenger apps IG, WhatsApp, telegram & Weechat. Rest are game for toddler. But all the time the phone been with her, her average SOT is like four hours and the BATTERY KEEPS ON DRAINING on Wi-Fi or Data and NEVER flats out. It only does when in airplane mode. Before you guys days uninstall the games, in the battery usage graph same with GSAMbattery, Android system is like up all the time. So it has to do with Android OS.
is Android really just like this? Do iPhones person better?
I have EXACTLY the same issue with my nexus 6 rooted. When my wifi is up, none stop drain and BBS doesn't show any unusual activity.

With 4 hours screen on time that is about what you can expect. Mainly when using things like weechat which is notorious for uploading all it data over and over again to its servers in China. Then you have whatsapp which is done by facebook which are known for some of the worst coded apps for battery drain in the market.
Your biggest issue is the screen on time. $ hours is a bit ruff on a device. As the screen is the biggest thing to take up battery. Unlike the iphone which uses a less intense screen due to its lower quality res.

Bro, you should use an iPhone and see! It's much worse than Android. iPhone have less size batteries and you can hardly get through the entire day with one charge according to your usage. Although apple's implementation of background apps optimization is excellent, but still the battery life is less due to small batteries. I feel android is much better in terms of battery.

You can add that android is still an open system which allows you to hard modify the system, apps behavior, etc.. So you can set your device especially for your daily use.
For example, the way I set my 2yo-phone gives me 8 to 10 hours SOT, which is faaaar from any Apple devices autonomy..

No it's really mostly just the screen being on. You can test this by setting the device screen to never time out and let it sit. You will notice that it kills the battery.

That is generic which means apps system api or systems the app uses. Like say the LG tones app. It uses the system BT api and if it drains the battery then all you see is BT at the top.

I'd say that you either have a battery that is past it's useful life, or you have some serious wakelocks going on. 2-2.5 hours SOT is awful. I bought my device used 9 months ago and can easily average 6-8 hours SOT over the course of 48 hours on battery (on stock 7.0 unrooted). I'm only now seeing a lower SOT with this current update to Google Play Services. And even now I still get 5-6 hours SOT in 48 hours.

I know the reason for my bad battery life. It's my signal. Signal here is spotty and if you leave town you lose signal all together. So my device spends most of the day looking for a stronger signal. SOT really doesn't mean much to me.

Yeah I normally keep late off. It doesn't help really. Signal is just too spotty. You can bounce between 2g,3g and lte in 5 min and never move. Then you have the times when the military blocks all GPS and unless you heard the announcement and turned GPS off that would also kill your battery. Then like I said once you leave town you have no signal for hundreds of miles.

I've tried different kernels, lineage/CyanogenMod, Pure Nexus, greenify, and even tried down clocking the CPU to 1.2 GHz or less at all times (shockingly, in normal use I couldn't tell the difference lol). Never got that much screen on time. I'm not even sure airplane mode would do that. My best was around 45 hours, but with about 3 hours of screen on time. And that was with the phone being less than 3 months old.
Currently I'm on stock Android, and getting 20 hours at best with 3 hours sot. At this point, I will say my battery is shot since it is a year old. But I'd love to see your settings and see if I could get close.

Here are screenshots of my battery use from March. 3 days with 6.5 hours SOT. I keep my screen at a relative 20% or so (lower at night). I have very strong signal (major city) And I use wifi about 65-70% of the time. I also actively moderate my screen touches (yes, they do indeed matter). I turn off NFC and I don't use BT. I also actively purge misbehaving apps (I refuse to install some, like Facebook) Other than this, I can't really say. Perhaps, I just lucked out and got a cherry of a system (with the exception of my headphone jack not working with mics...Grrr... and my camera's image stabilization Causing blur at certain shutter speeds)
