Go Comment or Star for Battery Fix

I'm sure we all know that the battery life on the G Nexus is pretty awful, so let's all go star and comment on the issue so we can get Google's attention!
http://code.google.com/p/android/is...s Owner Summary Stars&groupby=&sort=&id=22878
Just scroll all the way down to the bottom and star the issue or leave a comment too.

Done and done... I hope this comes before I need to return the VZ GNex

Hmm, compared to my EVO 4G, I barely had to do anything to this to get the battery life to be very good (estimate 100 -> 0 = 15hours). Maybe I use the screen less than you guys though.

At home, no LTE connection. 5.5 Hours.

On GSM.. battery life is stellar.. keep in mind, like the person who posted above me that if you are in a low signal area your battery will be destroyed searching for signal..

Yeah I don't have LTE where I am either, but I have it forced to CDMA only. Android OS is my battery killer. I usually get around 6 hours before having to plug it up.
I really think that if enough people starred the issue then it will get someones attention! (Crosses fingers)

Please star, but don't comment. There is enough useless comments there already, and everyone gets notified on new comments.

you probably have a rogue app killing your battery. if I let my nexus sit idle with LTE on I get close to 2 and a half days

Hi,
This high Android OS Keep awake time is not specifically about battery life issue.
We are discussing the fact that, because of this, the phone is constantly waking up (wake up state).
And that's should not happen while the device is turned off, for example.
Yes, of course, this will relate to battery life at the end. But, that's not the point of the discussion / bug as everybody has different preference of battery life. One can say 12 hours is enough, while others may say 24 hours is not enough, according their usage pattern.

Yeah I don't think that is the case... even after rebooting it stills is draining even when idle...

i aint charged in 3 days so im all good

This is nothing new. Android is a batt hog, plain and simple. You think google doesnt know this already. Its an "acceptable" item. Where they know about it & it's not the best, but thats what they get if they want a phone thats constantly using the network, has a large HD screen and is so damn good to look at you wont want to put it down.
Quit itchin and get on with it....

I have the extended battery from Verizon so keeping that in mind, my phone lasted 14 hours with 10% remaining with normal use. I stopped testing since I had to go to sleep
By the way I have Beweather and Facebook updating every hour and Pulse updating every 6 hours. I also have endgadget, Cnet, Google currents, Flickr and 500px updating.

So far battery life is a bit lower than I would like but not to a horrible state. definitely going to need the extended battery though. playing around today to see how fast I can kill it.
can't get photo to upload now though for some reason but got 2 hours 10 minutes with 12% remaining. would kinda like to see that as a stat added to phone reviews, minimum battery life. Max is fine but I'd rather know how long it will last with power using.

I'd say battery life was less than great on 4.0.1 but 4.0.2&.0.3 its pretty damn good now my idle usage is next to nothing. 2 days ago i had 47 minutes talk time, 1h38m screen on and about 13-15 hours of idle and still had almost 40% left at midnight.

I think you don't understand.
This is not about battery life, but the high Android OS Keep awake time. Which means your phone was awake when it's turned off.
Obviously, this doesn't happen on my HTC Desire, nor Nexus S with Gingerbread.

I can't speak for battery life on the LTE Nex as i have the HSPA+ version...I've found that the battery life is quite excellent after a few charge cycles...Have gotten 21hrs on a single charge with normal usage...if i'm watchin vids or playin games then im putting my phone on the charger cuz the screen really does eat up battery alot.

Screen killing battery

hello my phone doesnt last 1 day of charge and it says 40% is due to display/screen can anyone help me?

You can lower your brightness if it is not already at the lowest setting.

Unfortunately, the galaxy nexus has poor battery life. You could also try turning off data when you don't need it.
Sent from my Galaxy Nexus using Tapatalk

the screen is at lowest and it doesnt make sense turning of data if the problem is from screen right?

I'm having the exact same issue. Screen is totally eating up my battery life. It took 30 minutes for the battery to go down by like 10%. And the screen is 40% of the battery life issue.

Maybe I just don't use the screen as much as you, but I don't find this to be true for me. I find it has great battery life. I don't sit for hours with the screen on, but I do regularly text and check emails throughout the day, do a bit of web browsing, take some calls, and play some Angry Birds or other games in the evening. The screen is always at the top of the list for battery usage, but even on an extreme day I still have more than 30% battery left by the time I go to bed. I throw it on the charger and I'm ready to go again in the morning.
I disagree that the Galaxy Nexus has poor battery life, in general. I would argue that: all high-end phones have "poor" battery life because of all the things they do (especially 720p screens), your personal use of it consumes a lot of power and you could benefit from an extended battery, or you have a faulty device.

hi there, i do that exact same things with no games, so less usage but i get less than a day... i love the phone but the batery is just no working...

I don't understand why people don't get that when you have a screen that is 4.65'' it will destroy the battery life. My screen use is always at 60% or more but yet I still get good battery life. The screen is going to use the majority of your battery when compared to other things, that's just how it is.

sorry but thats not the point, when you pay 700 for a top phone, that is suposed to be the google experience to carry arround wiith you and you can only get 10 hours of battery time something went wrong in the process...

Most phones are $600 to $700, and name one 4g phone that will last more than 10 hours with moderate use and no extended battery, just not going to happen. You need to reset your expectations.

GN battery is giving lots of trouble, too. I picked up the phone from charge and it was 100% charged. ! hour of usage with 3g on. Usage includes 1 hours or music and reading of pdf books simultaniously and battery is dropped to 61%.

I think you should take a look at every other android phone that has come out with the same specs in the last year. Everything from the EVO 3d to the thunderbolt have their default battery's not last more than around 6-8 hours with constant use because of the screen & processors.
THis is why Verizon offered the extended batteries at a discounted rate right off the bat, because default batteries have never ever lasted that long in topof the line smartphones. FFS the new iphone 4s I've heard from a friend that their phones don't even last 24 hours.
I have a galaxy nexus, and mine has lasted... let me see.. one sec...1 day 3 hours and 25sec's with 35% left. (of course I have the extended battery) but here's the kicker: the extended battery has basically the same back as the regular phone does. so if they so desired, verizon could technically put out another extended battery just like all the rest of the phones, but they might not do that. I'm content with the battery life as it is almost identical as the droid X from which I came. The only difference is since I have a lot of un-updated apps for ice cream sandwich one of them is using "mediaserver" A LOT. I'm talking about that being the top of my battery draining with the screen being second. They both have taken ~20% with android OS itself taking 13, PlayerPro taking 13, and other random things like calls and txt msging taking ~10% each.
So I would suggest not trying to watch a lot of stuff on your phone while on battery, or don't expect your battery to survive long while watching stuff on that great screen

hymn thanks for the feedback so the only solution I see would be to go for a bigger battery. I'm from Portugal were could I buy one and whays the power?

If your screen usage is less than 50%, it be more worried about what else is killing your battery........

How are people getting such great battery life on the Epic Touch!?

I am watching this thread (http://forum.xda-developers.com/showthread.php?p=23272848) in amazement, as people report 24+ hours of battery life, with screen-on time of four, five, or even SEVEN hours!
I can't understand how folks get such great life.
Mine averages about two or three hours of screen time and about 14-18 hours, I'd say. I'm using Blazer 4.0, FB27 modem, and Rogue 1.4 kernel.
I know everybody's usage is different, and also we're all going to get different results due to other factors (signal strength, apps, etc), but I can't understand why the massive difference in battery life!
And I do have an 1800 maH battery.
Note: I do have a handful of apps, but not a whole lot, and I don't think any are destroying the battery. According to BetterBatteryStats, it doesn't look like the phone is having any trouble sleeping. That is, the screen-on time is just slightly lower than the awake time, meaning that the phone is typically sleeping when the screen is off.

With your usage, you feel 14-18 hours of battery is bad??? Id say a day of 16 hours consistently is pretty darn good. Now, I know that I have gotten over a day on battery by using it all day and then forgetting to charge it over night. Sleeping while the phone isnt awake can give some pretty outrageous looking battery life. Again, Id say if you are getting 14-18 hours on one charge, you are doing pretty darn good.

Im lucky if I can get 7-8 with all the "videos" I watch during the day

Well, I understand that when the phone is sleeping, it generally uses very little power -- especially on wifi.
It's mainly the screen-on time that amazes me. How can somebody get seven hours of screen-on time?? Just seems unreal!

Well I am assuming that their 7 hours of screen on time was doing something minor. Then again, these are electronics, and they are all different. He just may have found his perfect set up. But again, if you can get through your day, doing everything you needed to with your phone and lasted 14-18 hours, I would be happy.

disabling fb/twitter sync has helped my bat life improve.
always turning screen off when done rather than letting 1min timer take care of that whenever possible.
wifi is better on battery than 4g/3g. also disable wifi sleep.
other than that.. all comes down to extra 3rd party apps you have and personal usage.

I've never calculated mine all out, but I do get some pretty decent battery life.

Its all about how you use the phone. everyone seems to have there own definition of what "heavy" and "light" usage is but the fact is people getting 14+ hours aren't using there phone all that often. if you want to know how much actual usage time you can get out of the phone check the time the phone has been awake or the time the screen has been on.
for example my g2x goes for about 2 and a half hours of screen on time. my vibrant, 2 hours. havent had the e4gt long enough to see. these numbers of course changes depending on what you're actually doing (data intensive tasks will obviously cause faster drain) but it will give you an idea of how much you can actually use the phone before it dies. if all youre doing is texting here and there and checking email plus maybe 15-20 minutes of games or videos it isnt hard to get through a 10-12 hour day on a single charge. but if youre like me where i spend extended periods of time browsing the net while messaging and texting then the batter is going to die fast regardless of what battery saving tricks people suggest.

I recently removed OfficeSuite Pro 5 and noticed about 15-20% better battery life.
I also removed it from my other android devices and my tablets. Still testing them to see if theres a difference or not but so far it seems a bit better battery life.

I don't know. Just how much can you believe people who are posting on forums that they are not exaggerating? Take for instance the post below where this guy was claiming he got 11 hours of screen on time and STILL had over 50% battery left on stock battery. By far the biggest claim in battery life I have ever seen. And he was insistent on it:
http://forum.xda-developers.com/showpost.php?p=22293195&postcount=30
All I'm saying is take what people are saying about amazing battery life with a grain of salt.
I average about 3 hours screen on time, and occasionally get over 4 hours with ~24 hours total time. But if my signal isn't the greatest, like when I'm at work, I get probably 1.5 hours screen on time and 17 hours total time.

I'm currently at 14h 41m with display on for 2h 36m and still have 47% battery left (I'm on stock rooted EL29).

Your HOX battery life experience?

I see countless comments with people complaining about battery life not being good enough in most threads, and it being affected positively/negatively by updates.
I'm aware a lot of ROMs can have a very positive effect on battery life but I am more interested in the general overview – your battery life's life if you will! The reason I ask for your experiences is that I would like to qualitatively collect a bit of information from a fair few people and see what's to be seen.
It's worth noting that my latest HOX's battery life is exceptional and I believe it's down to a simple life/career change. It's really nothing new to someone who knows their fair share about batteries however I would be interested to compare.
So, list the times you wake up, take your phone off charge, put your phone back on charge, and go to sleep. If you can it would also be nice to know what your battery percentage is at certain points. It would also be interesting to know what hours you do on an average working week and in what sort of work environment (home/architect, office/marketing, shop/clothes retail etc).
If anyone can remember the things off the top of your head, even rough estimates just chuck then in the thread. I will then compare them all to my own personal habits.

Sent from my faster than SGS3 HOX.

Personally for me ICS was 4.0.4 was perfect, after update to JB it's really bad. On ICS i was loosing 1% of my battery during whole night on JB i can even loose 10% ; d. Overall battery drains faster during usage... all stock.

There's already a thread for battery stats.

Fantastic. I'm more interested in people's actual habits not stats about their battery because it only tells one half of the story. Like I mentioned this is more of a qualitative approach, so less battery stats.
I should of assumed that most people would be like more yourself so I will get straight to the point.
I have the benefit of working at home which means I can charge my phone whenever. I'm not forced to charge it over night; having it over charging for excessive amounts of time. I charge mine in the day and as a result I'm conscious when it hits 100% – I then unplug it. Other than natural degradation, I doubt I have ever damaged my battery in any way which has left me with a great battery life.
I was quite interested if most people charge their phones at night, go to sleep, unplug their phones when they wake up etc. This will severely accelerate the degradation of the battery.

well for me, ICS was bad...im using custom rom and various kernel to see which has the best battery life...all bad accept ncx 0.99....well some of the time its ok but some not...the battery percentage in ICS if not using will stay at 1% but for a 5 minute use, it will drop 10%...but amazingly, if you keep using in screen on, wifi or whatever, it will not drop that fast, well for me its ok....but now i have updated to JB still in stock, and the battery life is great.. i have watch HD movie using MX player in 2 hour and only drop 20%....when in ICS about 80%...big difference....i think stock kernel is best...

Well for me it's decent i mean yes it could be better but it's okay... heres my usage: i take it off the charge around 10 am when i wake up or so and it's off the charge till the next day morning with avarage 45-50% battery left and screan on time avarage 2:30 hours - 3 hours, sync with FB , hotmail and weather is On all the time as well is the wi-fi even when i sleep, my reception aint so great tho , around 2-3 bars top 4, 2g network, anyway my tops on the screan time would be around 6 hours with around 30% brightness idk how that guy managed to achive 6hours 20 mins on a single charge on medium brightness , could be jelly bean or maybe partitial charges ( i'm on ics btw ), anyway hox battery aint so bad as ppl may think, besides if you're lucky enough you'll get hox + battery into your hox ( 2100 ma ) which should provide avarage 6 hours + screan on time, tho i bet we could get around 8 with that battery. Hope this helps.

Ive got arhd and i got to say Im happy with my battery life, first I wasnt, when I went through a couple of charge cycles it got better and better. Now I can do 3.5 hours on screen time playing games and use it for atleast 24 hours with a mix of everything with watching videos to on the bus lol. So mines has been really good.

Battery has been pretty bad on any ROM. Now that I have ICJ421, my battery is near perfect. Yesterday I got 14h with 3h22m Screen On time.

Battery Reducing Quickly?

Hello everyone, new to the forum since I just picked up my note 10+ and thiught this forum seemed more knowledgeable than others for battery issues or issues in general. I dont really know if it's an issue but I'm curious of how others people batteries are acting for their note 10+'s. Mine died a few hours ago and once it hit 100% I removed the charger and didn't use it for just over an hour and I noticed my battery went down to 2%. I have my always on screen on of course, most of the apps were dead and I did optimize the battery in the settings while my phone was charging then stopped using it until it charged fully. So I had no apps open and I had a version of battery saving on. I did medium but left the higher res screen on including the cpu at 100%. Would this cause my battery to go down 2% in an hour without any use?
For a side question, is there a better way to get the most out of your battery? I always thought it was let it die everyone inna while but I read recently charging it to 80 then letting it down to 60 and back up to 80 and repeat is the best? If that's true, how do you keep that up and how long will you need to keep that before normal chargers?
Thanks. Hope someone can help

If it went down 2% in an hour, that's 50 hours of standby plus always on display. That's crazy good.
Sent from my SM-N975U using Tapatalk

Best way to go is using normal charge an never let the battery drop below 20% forget about trying to maintain certain range (60-80), it will just drive you crazy

If I put my iPad mini to sleep at 100%, I wake up the next morning with 100%. Maybe 99. But usually 100.
That's not the norm, and it's not perfect apples to apples, but it is possible.
Also, 2 days of standby with zero use is not unusual, but definitely not "crazy good".

So besides that little fight you had with the other forum member (lol) I appreciate your comment. But there seems to be back and forth, one other person says its good, another says its not. (the one I quoted below). Just seems weird to me that with no open or running apps and just the always on display running that it went down in an hour in 2%. Searching around, people saying losing 1% In an hour with the same set up, no running apps with AOD is bad. I kind of agree since its not truly in use. But unfortunately I cannot find any battery standby tests from Samsung or anyone else to confirm it.

I agree with you more honestly that it shouldn't be going down that fast in an hour with just the AOD running. I didn't have any apps running once it 100%, I was on it while charing it to around 50% but then once I knew I was putting it down for a while I ran the optimization and had the phone kill all the apps. When I saw it go down the 2% I did check out the apps using the battery and the AOD was the only thing listed. Maybe I didn't charge to a full 100%? even though it said 100%... Ill check it out tomorrow once I charge it fully again, today I was charging it up and down most of the day sadly. I try and keep most apps from not running in the background, some I do need though like for my IoT devices needing to know my location, I have yet to change that to just using LTE as my location GPS, but that was not on last night all. Ill try out the sleeping apps though, I didn't know there was a setting for that. Thanks again

AOD typically consumes 1%~2% in my past note devices(7,8,9)

Battery optimization takes a little bit so if you just started using the phone give it a few days.
Also, package disabler or ADB can be used to turn off any major things that you are not using (i.e. Bixby or DeX).
Regarding Cell life: Yes between about 30% and 80% are the optimal percents. That doesn't mean try and always keep it there, that would just be silly and unrealistic.
However, it is important to be conscious of this. For example, don't leave your phone on the charger for days on end sitting at 100%. Don't leave your phone in a drawer or a backpack with 0% in the cells.
Cells are technically damaged (or worn would be a better word) every cycle. The most damage comes from when the voltage drops to its lowest point and its highest point. (i.e. 0% and 100%)
For example, if someone were to charge a LiPo or Li-Ion battery only between 30% - 80% for an entire year and another person with the same phone always went down to 1% and always to 100%, the latter phone would have more cell wear thus it would not hold as much power.
Once you learn of this and become conscious of this then you tend to adjust your habits. All other myths and theories about battery calibration have really not been a thing in many many generations of Android. While you can screw up battery calibration through a service menu, rarely (if at all) a battery loses calibration. Most people start seeing battery wear and think its a calibration issue and then seek ways to fix this. At that point, it cannot be achieved because there is a physical change to their battery which can only be refreshed by getting a new battery.

Reporting my battery life. I guess this is truly an all day device.

Give it a couple days to settle. The first three days, mine got pretty bad battery life. Then yesterday I got almost 10 hours of screen time after using it pretty heavy all day. Mixture of Facebook (battery hog), Internet, texting, emailing, and using the camera (also a battery hog). What finally killed the battery was me downloading, installing, and uninstalling multiple versions of GCam trying to find one that worked well enough to use. I finally found one before my phone hit 0%.

In an hour? Last night I even scheduled it off and had no running apps and medium power saving mode fully on and lost 5% battery in roughly 7 hours with no use.

Battery optimization takes a little bit so if you just started using the phone give it a few days.
Also, package disabler or ADB can be used to turn off any major things that you are not using (i.e. Bixby or DeX).
Regarding Cell life: Yes between about 30% and 80% are the optimal percents. That doesn't mean try and always keep it there, that would just be silly and unrealistic.

This is useful, thank you. Never knew not discharging device is the way to go but we all learn new things every day. I'm at 65% right now, when waking up at 6am with 95%. Wireless android auto for about an hour, plus okay-ish use. Ill make sure to charge it up to around 80% tonight.

Thanks, I think I am seeing a bit better today after having it for 4 days or so now? Ill follow the above quote about calibration and go from there.

Over 8 hours screen time is great, best I've gotten so far is 7.5 hours

I just wanted to throw my two cents in here... My battery life is pretty terrible in comparison to my S10+. Trying to find a rogue app of some sort but I just hit 1% with 12 hours off the charger. Keep in mind that is not 12 hours of use. In fact I used it for about an hour of total screen time today.

Yeah I came from an S10+ and noticed my battery on the N10+ was pretty bad in comparison.
I did restore everything from my S10+ though, not a clean install of everything.
Wonder if that may be causing issues.

Is everyone having problems on Verizon?

Unless you put it in airplane mode, your phone will keep connected to cell tower (or wifi if you have wifi calling) otherwise you won't receive calls and messages, so there is no such thing as phone with no use, and if you have weak signal or some interference your battery usage can increase drastically even in standby because the cell radio will try to connect at full transmit power. And then you have all those programs running in the background, God knows what they're doing. As others suggested disable programs you don't use, also you can force close programs that you don't use often. When I had my older Note rooted, I optimized it so well it would run 2% down per 8 hrs overnight, but it took some effort. Biggest problem is to know what to disable without loosing functionality for stuff you need. Give it some time for people to learn more about new phone. BTW my 3 day old phone has 435 apps and services installed and most of them I have no idea what they do.
