My biggest gripe with this phone: Battery Life

I LOVE the Galaxy Nexus, but the rate at which the battery discharges is just ridiculous. I'll use the phone for 15 minutes doing things like Twitter or Web Browsing, and it'll discharge 5% in that time. To me, that is horrible. I'm being really conservative too. Throughout a day I try not to play videos, games, or anything else intensive because I know it'll ruin my battery life. Even on standby it discharges 5% in an hour. Typically I lose about 10% an hour and my max has been 12 hours so far.
I have auto sync turned on and keep the screen low when possible. I NEED auto sync on because of the nature of my work. Compared to my iPhone 4S battery is downright pathetic.
Today my usage consisted of one phone call, a few text messages, lots of Twitter, and light web browsing. Nothing too crazy. Again I'm being really conservative with my usage whereas on my iPhone I can do whatever I want and not worry. I'm just not seeing how people are getting 15+ hours and claim heavy usage. I'd love to believe that! The battery drains so fast during normal usage it may be a deal breaker for me.

It sounds like your definition of light usage is wrong.
I wouldn't consider heaps of twitter and some web browsing light usage. I would consider it moderate usage, in which case you seem to be in line with everyone else.
I agree with you in that the battery life isn't quite what I would have liked. Ideally I wouldn't have to worry about battery at all, and I'd be able to play games and browse the web as much as I like, but for normal usage it's fine.
The next Nexus though, man, that will only have to be charged once a month. I can't wait.

Twitter hardly taxes the processors at all. Refreshing it every so often should hardly take any battery life at all. Web Browsing I can understand, but my total time browsing today probably amounts to 10 minutes total.

I wonder how much of the drain is attributed to the 4.65" screen. It's a monster.

I expect the battery life go improve within the first few cycles. I had a similar experience with the Nexus S last year.

Most of it. 720p Super AMOLED HD is killing the battery. The only way to last a long time is to not turn the screen on.

I've had the phone for a week so far.

almost 3hours of screen from 10h standby!! mate give us a break and get back 4s. !!
heavy usage not low!
i can see low signal (coverage) what can also produce higher battery drain.
twiter running 24/7 in backround sync on + wifi + games...
i dont know what you want... you will never get anything similar from for example HTC sensation or even your favourite 4s.
dont take it on bad way..but if you dont know what to do - try to save your battery..
-lower your screen britness
-remove/disable apps that are producing the heavy drain (use betterbatterystats app)
-stop playing games - if you wanna long life for your battery.
-etc...
Best regards

People using a G2x claim to get a day and a half... I'm lucky to get out of work. Push email for work is to blame I think. I get tons of emails (100 a day) and I think its taxing. From your pics, the screen used over 50% of it. That's a lot.
Sucks.
Also make sure your aren't turning on the screen every 5 minutes to check the status. Since your coming from an iOS, are you closing apps properly (back = close, home = minimize).
I'm not saying your crazy but just saying.

I had the same thing happen with the Nexus One. The battery wasn't that great but, got better after a few charge cycles.
I've never had a Android phone that could match the battery life of the Iphone. I can sit the iphone down at night without putting it on the charger and, if it's at 100% it will be at about 90-95% when I wake up. I did the same thing with my Mytouch 4G and, it was at 15%
To the OP, I would recommend keeping a charging cable with you when you out and about especially in your car. I've had car docks with a few of my android phones and, always keep the phone docked when I'm driving somewhere. It really helps.

What you also need to remember is this is the first release of ICS and is still in development so battery life my be improved in the next update. Like you mention iPhone4S there was massive battery leakage in the first release of IOS 5 which Apple apparently fixed in the newest update.. So maybe in the next update we can expect some bugs ironed out.

Used to only have ONLY 2-3 hours screen ON on my Vibrant so I know how SAmoled looks like.
I know iphone battery is good, but you need to consider the screen size too..
Get a spare battery with your "light usage", but I am thinking how much would it cost becoz of the NPC antenna.

Too good thing is, unlike iPhone, you can buy a spare battery and carry it with you.

3 hours of screen use is what the problem is. That is a long time. I wouldn't complain about that at all.

I already said I didn't play any games today and my screen brightness is low. For some reason Shadowgun stays in the battery info screen. I played the game two days ago and manually closed it out. Even after rebooting the phone its still there.
I'm being 100% real, stop trying to make excuses or act like I'm an iPhone fanboy. The Galaxy Nexus combined with ICS is the best phone I've ever used! I'm just terribly disappointed with the battery life.

Twittering all day is sucking up battery because of all the data use. Dude, youre not a light user with 3 hours screen time moderate, possibly heavy depending on background stuff sycing automatically. You have some tweaking to do, not whining.

3 hours is not that much. Seriously. It shouldn't be damn near dead after 10 hours. Imagine if I decided to play a game for 15 minutes or watch 2 YouTube videos.
I bet if people were getting an hour and half with this phone, all the fanboys here would say the same thing. "Man, an hour and a half is a long time! You should be happy with that!".

I've tested out the battery difference by turning off auto sync. Doesn't make a difference at all. Fact of the matter is that the battery drains like crazy when the screen is on.
I'll just turn my phone on because actually using it is frowned upon here.

Display is killing battery...HELP

Alright so my display on the nexus is always using anywhere from 49%-53% and I have it on the lowest brightness setting. How do I get it lower? any sugestions? Also, I got the phone on christmas and the most battery I've been able to get is 12 hours using the phone not at all.

The display on a phone like this will almost always be the highest percent user of your battery, unless you never turn the screen on.
The more relevant question is how much Screen Time On are you getting out of a single charge?

Maybe you can open you phone and disconnect the display (have a look at http://www.ifixit.com/Teardown/Samsung-Galaxy-Nexus-Teardown/7182/1) it may help. Hopefully voice control works fine

Remember, its just percentage. The lower your screen % the higher everything else is drawing. You have to expect the screen will always be the biggest drawer. Better to go by run time, how long you are getting out of your battery before it dies. You still have quite a bit of life left at say 20% battery.
Turning down brightness is the most you can do, other than being proactive about turning the screen off when you are done and not letting it time-out.
Eventually new software will help with battery life; using custom roms with later releases has improved consumption. Also remember to turn off wifi if you are not using it. Big hog

When using my phone, the display is always the culprit for battery usage. That's normal.
If you don't use your phone heavily and only get 12 hours, your problem is elsewhere. What do your battery stats say (settings -> battery) ?
edit : typo

Isnt there a thousand threads on the internet about screen % and battery life

The display will most likely always draw the most power but you can do two things. First you can lower the brightness, and second, you can use black wallpapers because super amoled screens use the least amount of power when displaying black

This seems to be incorrect from a test someone did on this forum.
Basically on lowest brightness - white and black appear to use roughly same.
On max setting, white killed the battery in half the time that black did.

No, but if you have a choice to extend the battery 1%, by simply choosing something as simple as a darker wallpaper, I see no issue with the advice. Everything you hit the home button you'll see the wallpaper.

I prefer having a nice colorful wallpaper than a black one that would extend my battery a few %. It all depends on how you use your phone and what are your needs.
Today I've used my phone heavily (web browsing and google reader, gaming, bought a new bluetooth headset and played with it, 30' GPS with Google Maps, etc) and I'm at 38% after 17 hours, with an animated wallpaper. Not too bad...

This is my battery status from my display. Its not on the lowest setting, maybe 10% at most.

It's like every incarnation of a phone with an SAMOLED screen shocks people. I don't know why. The screen sucking juice is about the biggest, "well duh" concept out there.
It is what it is. All ya can do is live with it, or get a phone with an old TFT display.

unremarked said:
I was hoping someone was going to explain how to read the percentage but apparently no one is going to.
First, and I'm going to use the numbers from your last screen shot, your screen is not using 42% of your battery. Your phone has discharged 12%(meaning that you're at 88% of full charge), and 42% of that discharge went to your screen. 58% of that discharge went to the rest of your phones system. Does this make sense?
The screen will always have the highest percentage because it is the main way you interact with the phone. If something was above the screen, then something is wrong. Further the percentage will always change as some things are used more or others used less.

There are reverse LCDs that use power to make white, but virtually all LCDs need backlighting, so the tradeoff is less important. Also, LCDs really (theoretically, at least) only use power when changing state. As long as the display isn't changing, the power usage is virtually zero.
All that said, reducing the brightness on my gnex makes a HUGE difference in battery life.

That's roughly what I will get with brightness at about 70%. The battery life is not great on this phone, PERIOD. Just enjoy the phone and charge it when it needs to be charged (it charges up really quickly).
It is amazing how many people have 3-4 hours to be spending on their phone a day.

Well I might as well finish off any questions since this was revived
LCD screens use power even if the pixil was black. They use power even if the image is not moving.
Amoled screens (our phone) are the same as LCD except that black pixils don't use any power.
E-ink screens are a different matter they don't use any power when nothing is changing and they only use power at at the pixils that change to display the content. The issue with this tech for general display use is the refresh rate is a Max of 10 fps on the new displays. The new color displays are washed out.
The reason our battery life is like **** is because of our large displays and that poor battery does not have enough power to keep them going. They are the main power suckers of all electronics and our CPU takes a fraction compaird to them.
These kernels help by being more efficient with the power and undervolting the CPU giving us a idle time of over 20 Hrs.
The reason people can push 5 Hrs screen time is because of these black themes helping the screen use less power. Its the reason black themes are soon popular. In general your lucky to hit 3 Hrs its not that its defective its just how it is
I hope this clears some things up

With the watch, how is your PHONE battery life?

I have Note 3, stock 4.4 and rooted. I can usually go from 7am to 6pm with 40% battery left.
With the watch, now I have 13% left at the same time.

I know in the office tons of people use Bluetooth. I can scan my office and the Note will show all kind of devices. Mouse, keyboard, phone, headset, etc.
If broth interference is the main cause, there is really nothing I can do to stop this from decreasing my battery life. [emoji25]

That's most likely the cause. I've read some articles that have blamed high bluetooth traffic for battery drain.
I would check your battery life under similar use during days you're not in the office if you'd like to say that is for sure the cause.
I wouldn't be surprised if moto makes more bluetooth improvements in a future update that helps the battery, just like the last one.

I have a Nexus 4 so it's ****ty as per usual

LG flex here. With watch I unplug at 6am and plug back in at midnight. With light/moderate use I end up with about 40% but I'll torrent and play games on my lunch break so it's more around 15%

The Android wear thread goes a bit berzerk when you shut off your watch, constantly trying to reconnect every X seconds.
That's really stupid - it should be triggering on whenever the bluetooth connection to the 360 is re-established. My phone has been OK otherwise (I think)

My battery life hasn't really changed at all on my phone. I guess it's possible that the reduced time I use my screen due to the watch makes up for the battery drain from bluetooth?

As been mentioned, if your phone and watch are out of range Android Wear will chomp away at your battery. I leave my watch on my desk at night and my phone on my nightstand (which apparently is just outside of BT range.) . If I do not disconnect Android wear, it will crush my battery when I unplug the phone in the morning.
For now, I just disconnect Android wear before bed. Hopefully a widget will come along at some point...or a tasker plugin
As far as when they are connected, any battery hit I take from Android Wear seems to be more than offset but the reduced screen time I use on my phone.

Have rooted Note 3 4.3 and Moto 3 watch... No battery issues here on phone and on watch...

I have a OnePlus One and the battery life has gone down some with the 360. When I check my Wakelocks, the "BlueToothRemoteDevices" is usually near the top. It's not too bad though, the OnePlus has a huge battery and great at battery management, so I still end the day with plenty of juice left.

Galaxy s5 battery life is exceptional. Even with the 360.

Just 1 hour screen time though.

With the one plus one, I go from. 7 am to 5pm and still have 60% left with about 3 hours screen one time. I easily can go 2 days with the Moto 360. It's mainly a notification device for me and watch so I'm not always playing with it
Sent from my OnePlusOne

I am having the same massive phone battery drain using the Moto 360. I don't have a problem with the watch battery life. But I certainly do on my phone. At work I don't use the phone (or watch) and the phone normally drains about 8% or something. Now that I have the 360 and Google Wear, my phone battery is more like 72% when I get home and almost all of that is shown as being used by "Google Wear".
This is a Nexus 5. The two are always within about 3 feet of each other. I have Google Now OFF. I have not installed any "apps" on the 360. I rebooted both this morning as a test, made no difference. Four days in a row of this now (since I got the 360). So then I tried to factory reset the watch and resinstalled Wear on the Nexus. No change.
As an example: Today I demoed the watch to two people. I did almost nothing else the entire day. I had no notifications at all. Almost 10 hours off the charger. I made no calls. I had no texts. I didn't even wake the phone AT ALL. 20% of my phone battery disappeared and 65% of it was ANDROID WEAR! 55m and 15s of CPU usage on WEAR???!!!?!?!! Why???? What could possibly justify that much load/power?
(Oh, and the watch only used 25% of its charge during the same period) ((Posted on the G-Watch forum, since I found a similar thread there first, but this forum is more appropriate))

Not to sound rude but you are complaining about going almost 10hrs and losing only 20% with a bluetooth device having constant contact with the phone?
That isn't "massive" at all. The reason it's 55% is because you didn't do anything with your phone at all, apparently. If you had done ANYTHING ELSE at all Android wear wouldn't be at 55% because that is how it works. It's that high because nothing on your phone was doing anything else.

Yes. Most people are reporting almost no power usage from Android Wear. Reporting 65% battery use for something that is or should be almost "idle" is crazy. I have used other "real" bluetooth devices all the time and have never drain like this, and they certainly don't consume almost an hour of CPU time.

Of the 20% of the battery used, 65% of that was Android Wear. It doesn't matter what else MIGHT have been going on with the phone, Wear, alone, is draining power at the rate of 1.34% PER HOUR doing what should be essentially nothing. And yet that "nothing" required an hour of the CPU being busy? Put another way- if I were off the charger for 16 hours (a full awake day) I would be losing almost 22% of my battery... for nothing. Now, if I were actually DOING something with Wear during that time, it might be worth the 22% across the day.

it is doing something, it is talking to your watch.

On my Nexus 5...
Before i had the Moto 360 i'd end the day around 50% battery left.
With the Moto 360 im getting 40% at the end of day. (Moto 360 is @ 30-40% also with normal use).

LG G4: Battery Drains 1% Every Minute

Hi guys my lg g4 is draining battery about 1% a minute when in use. Simple things like texting or web browsing cause this. This is a serious problem. My previous phones never did this. I dont know if this is hardware or software related. What can be the solution? Samung s6 has a smaller battery but outperforms the G4. My brothers iphone 6 plus has better battery life too. So i want to know what is wrong with the G4 which has the biggest battery out of the two.
Sent from my LG-H815 using Tapatalk

Same problem for me.. have to use spare battery and power bank when I'm not home. Drains super fast.
Also, you can't compare to iPhone as the software is super optimized and the hardware not the same (power friendly CPU and not the same amount of RAM). Plus they added some features to improve battery life.
I can tell, as my bro owns an iPhone 6 Plus too, the SOT is insane.
While doing same activities for 1 hour, my G4 is down at 75% and his iPhone is ~90%. On a day away, his phone lasted without problem while I struggled with my equipment to get 6 hours of SOT.
Meh.

Well the iphone aside but lets compare the galaxy s6 for instance. It has a more powerful cpu and smaller battery but still outlasts the g4. I don't know what is causing this. The operating systems are the same. Both running the latest os possible but getting different battery performance. I believe its a hardware problem more than software. What do you guys think? Can it be software problem?
Sent from my LG-H815 using Tapatalk

Something is wrong then gyus. I get almost 1h SOT from 100% to 90% web browsing.
Maybe is some rouge app or something else.

agree with chaki-, I'm currently ad 75% with 1h screen on time using HSDPA/4G connection. something is messing up your device.
you could try factory reset and monitor your battery life without installing any app to check whether it's a hardware battery problem or not.

Im running the latest os possible. I dont get how samsung s6 can have longer battery life compared to the g4. We have a bigger battery plus the s6 has a more hungry cpu. So how is that possible?
Sent from my LG-H815 using Tapatalk

I have found that Google photos does drain mine. I have to keep going into that app and change to backup on charge only. Otherwise it just keeps going and going. Battery drain with that is like 2% a minute

I understand you might have to disable certain apps etc but im talking about general use. Straight compare with the galaxy s6 our battery performance lacks. I dont see how that is possible. We should have much better battery life compared to most phones.

Neither do we so start posting your battery usage screens. preferably at the end of a battery cycle. no point posting at 80% or 50% left we want to see what it is at 10% or whatever low point at which you decide to recharge.
do you see any items above 'screen' in the battery usage list. if so, click them and screen shot them too.
You did not mention whether your usage is wifi or data, mixed ? what is the split.
Oh and is this a new device you just got. How many recharge cycles have you had so far.

Screen discharge on is 119% and when its off its 57% (!)
why ?
do you have many widgets that are updating. what about your wall paper. Is it custom, how big is its file size ?
This is just one thing that is killing your battery every time the screen is off and when it is on.
Try removing widgets and using a very minimalist wall paper, run it a couple of cycles and then tell us what your screen discharge figures are.
Also, you can't compare to iPhone as the software is super optimized and the hardware not the same (power friendly CPU and not the same amount of RAM). Plus they added some features to improve battery life.

iphone has an auto-lock feature which allows it to sleep without being disturbed. There are equivalents in android but not built into the system.
it also allows to restrict apps from refreshing in the background. If you can do the same you will get the same result if not better.

Just a few widgets used with Smartbulletin display and the stock one with clock+weather. Also, wallpaper is Sony default animated, I got the apk working from my previous Z3. Color is black.
On the other side, boot is managed so only few apps can start and ops too thanks to Xprivacy + hidden menu.

Do an experiment, remove ALL widgets and use a simple wall paper. not live. file size of wallpaper must not bigger than 50kB.
Do two charge cycles. post your screen discharge on/off. also post your gsam.

I most of the time use 4G. However my point is a straight comparison to the S6. With both running the latest os possible and same usage style. So i dont understand how the s6 comes out on top with a more hungry cpu and smaller battery. What is wrong with our device? You would think we should have better battery life compared to the s6 or even the note 5. Its upsetting to see the phone lack in battery performance

This will kill a battery quickly if the signal isn't good. Relying on signal bars isn't enough
The way to tell how good your 4G signal is to go to settings->general->about device->status-> look for signal strength
there will be a figure there in dBm. How much is it ?

Its not a signal problem. I have already isolated that from the start. My comparison was with the s6. How can it last longer when we have a less hungry device with bigger battery

Because something is draining your battery faster than on the other device. As to what that 'something' or 'something's remains to be determined.
state your sot and total run time.
Btw how long have you had this device ? how many times have you charged it.

2 months i had it for.

I can see lg g4 is not power efficient like the s6. So we can never get the same battery life as the s6. Even though we have a bigger battery. This is really unfair.

what is your avg sot/run time. when on wifi and when on data. second time i've asked this basic question.
in two months what have you tried to do to improve battery life.

I tried to minimise brightness to about 30%. Deleted all the extra apps. Updated to the latest os. Updated all the apps on the phone to latest available. So something is wrong with the G4 in general. From what i read on the tests professionals have done is that the G4 isn't efficient like the s6. So this must be totally a software related problem. Os is not optimized to be efficient. This device has let me down in regards to battery life. I would most likely want to go with another device probably the xperia z5 premium. However i dont know how the g4 would perform with the marshmallow update. That is something we have to wait and see. Hopefully LG do a better job at it this time.

Did you try a factory reset.

I tried resetting too. I dont know whats causing it

I looked into this ... my search led me to purchasing a second huawei watch off eBay that I keep in my pocket in a tiny velvet pouch. I swap out my watches halfway through the day, they are exact same, nobody knows I swapped them. I do this because I have a rooted watch with skin1980's high performance kernel and I use it a lot for voice commands and tts (I have a driving job and I have to go hands/eyes free). I also keep brightness high and screen is always on with tilt-to-wake activated. I'm constantly speaking texts, speaking navigation addresses into the watch, having it read my texts and notifications etc. I've found this watch to be THE BEST interface for spoken voice commands that are immediately acted upon reliably.
so basically, I need 2 watches to run them at full potential so I can drive safely. my watch usage is not normal.

This actually made me laugh quite a bit. It's a sneaky move through.
I am planning on replacing my hw1 battery. I've done it once to a moto360 and it worked.
I don't think there is a compatible battery with a higher capacity available though... I wish I could just use the hw2 battery

I ordered this one from Ali Express. The original is 300mAh, this one is said to be 800. I hope their quality claims are true as well.

ah interesting, tell us your findings once you receive it! 800 seems extremely fake though... Also the reviews estimate it to be 450. But anything more than the original is already a win.

I left it charging now, probably will take for a test ride tomorrow. Note that the battery capacity says it can vary between 450 and 950 mAh, therefore either it's all 450 I think, or it's a lottery. It is taller and slightly thicker but it went in just fine.

Ok, so I am heading back home after an 8h work day. My watch battery meter is at 55% with low day usage (with always on display, voice control and motion detection turned off). My old battery would give me something in the area of 10 ~ 20%. Now, there is also the factor to considering that my old battery had some usage, even if I hadn't use my watch for a while, so this comparison is probably with 1,5y used battery, so I also don't think it is an 800 mAh, maybe 500 mAh?
I noticed a few weird things, when I took it from charger it only had 90% charged, not sure if it needed more time (I left it overnight) or if it got disconnected or something else. The first 5% dropped really fast when I connected it via Bluetooth to my phone and then it stood steady at 85% for a while. The other greatest drops where when opening the Play store on the watch and installing apps, but the rest had some steady decrease. I'll see tonight if I can reach 100%.

Ok, so second work day, this time I'm returning with 78% battery. I left with 100% this time and had about the same usage.. I'm guessing it also spent some battery on app updates yesterday.

Are you then saying that the new battery is outperforming the old battery significantly?

At this point I'm confident so. I mean, it won't compare to modern watches batteries nor I think it will allow it much power usage but so far seems it makes the watch usable at least.

Thank you very much for the information and updates on this battery. My HW1's battery seems to be doing fine at this moment but I think I will order one for a backup. I don't put my watch through much during the day and I keep the screen off unless I need it on. I have heard too many stories about screen burn in on these watches. I even switch faces every few days as an added precaution. Thanks again. :good: :good:

ah, too bad I forgot about this thread when ordering my battery. In the end I got this one: https://www.aliexpress.com/item/4000149469709.html
The battery life is definitely better than with my worn out battery! I'm into the second day with about 52% left. My usage has decreased quite a lot over time though.

@skunks11111, How long did it take for your battery to arrive from Aliexpress? I have not ordered the higher capacity battery yet but I am still considering it as a backup.

I just did this. Ordered it from aliexpress. It took about almost 2 months to arrive to Toronto. I would imagine now it will take more since Christmas coming.
This is day 2. First day it lasted me about 14 hours from 100% to off. Day 2 it lasted 11 hours. So far happy with it.
Note to be careful taking the screws out. I strip all of them when getting them out. I realized the white (look like plastic) things that came along with battery and tools are to help with this but I realized too late.

I still have not ordered the 800mAh battery. My watch is still doing about 2 days on the original battery. I do keep it in do not disturb mode when I am not using it. That really saves the battery for me.

Ya, I have everything on and use it a lot.

I am glad that it is working well for you. And thanks for the heads up on the screws and case tools.
