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.

TIPS for Improving Battery Life

Hey guys, so i've noticed that a lot of people are complaining about their battery lives. There are a few things that I have done which are not too complicated that I think the rest of you should do too (if you haven't done so already). With these steps, i have my brightness almost to the max the entire time, and the battery lasts me most of the day without needing to charge.
1) Calibrate your battery - This first step is a given, and should definitely be done, especially after rooting. You can find steps by searching in the forums for how to calibrate battery.
2) Uncheck "Use Wireless Networks" in the Locations menu in the settings. This is a huge battery hog, if not the biggest on the phone (next to brightness and 4G). If you feel like you need it to use the "Places" app better, then you can either always turn on GPS just when you need to use it, or just search for whatever you want in Google Maps directly. Many ways around this problem.
3) ROOTED USERS ONLY - Get a root explorer, go into /system/apps and move the following apps to a different folder, preferably on the sd card: Socialhub.apk, Mediahub.apk, Sprintzone.apk, SprintID.apk (sometimes called w_sprint.apk). Obviously if you use those apps, dont move them because you'll essentially be deleting them, but from my experience most people don't use them, and they are always just running in the background. Huge battery hogs as well.
- You can also delete the other sprint apps through the usual app removal process if you'd like.
Also, if you use widgets such as Beautiful Widgets, or Minimalistic Text, for time and weather that require Use Wireless Networks for updates, it would be best not to use them. Especially BW, drains a good portion of the battery. There are other alternatives that I feel are just as good, such as a decent looking modded stock digital clock and the genie widget from ICS (Thats what i personally use). They take a fraction of the others and provide the same information.

Very nice tips. I didn't really like media hub and got tired of seeing it.. but the sprint files you mentioned weren't in my folder.. The apps are still there
EDIT.. also can you like me to battery calibration instructions? O didn't even know that was a thing...

You can also freeze those apps if you are rooted. Same results

How do I go about doing that?

I am always so surprised to read people with bad battery life. I have a stick phone running all sick items except having root and I well easily get well over a full day on my battery. I plug it in asst the end of the day with 60% battery on a regular and that is after 14-16 hours. GPS always on, brightness on auto, sync what needs to be synced, using the phone as a phone, with Bluetooth at times as well. The only time I lose significant power is when I use Netflix or start running games for an hour or so.
Are people running stock on this or a built ROM? Also, are you running stock kernel with CWM? CWM put my battery into a hole so I went back to stock without CWM, no idea why out would do it though.

It seems to me like from those pictures that you barely use your phone for other things than making calls. The reason that i can come to that conclusion is because your display battery usage is just so much less than your Android OS, that just means your screen is off for the majority of the day. I'm assuming from that that you're probably an older gentleman who has less use for things like texting and Facebook. Unfortunately, the majority of my communication is through those 2, as well as some other channels.
And to answer your other question, i am running stock rooted without cwm.

I guess i can just describe it for you, its pretty simple. Just follow the following steps:
1) charge your phone to 100% (if it reaches 100 unplug it then plug it back in, it'll most likely take another 20 minutes to truly reach 100)
2) if you are rooted and have clockwork mod recovery, boot into recovery, and wipe the battery stats. Then continue to the next step. If you are not rooted, dont worry, just go onto the following step anyway.
3) from the market, download a battery calibration app and calibrate it.
4) then use your phone regularly throughout the entirety of its battery cycle (don't plug it in for mini charges until it fully dies)
5) when it dies, recharge it back to a full 100% (don't unplug it before it reaches 100%).
Then you're done.

I wouldn't jump to that conclusion. By the end of a 16-hour day, I have about 2-hours of screen-time, and my battery is around 50%. I have corporate email on my phone, so it wakes up frequently, and I check my messages all day long.
There's also the issue with Android OS taking up way more of the battery charts than it's supposed to. Most of the time, that bar is 2x longer than my display bar, unless I unplug it and play a game for four or five hours. There is a bug on this phone, that either calculates the Android OS bar improperly, or the phone is genuinely using tons of battery in the background and Android OS is a giant battery drain.
If you hang out on the forums a bit longer, you'll see this pop up pretty often.

lol, I've actually already read those forums before, but the thing is that I just don't think its a bug with those people. The thing is that its simply a balance. If your screen is set to a very low brightness, or just off most of the day, it clearly won't be the main battery drainer, but all that means is that something else will be. Something will always be the main battery drainer, even if its not draining that much.
Maybe it just makes more sense in my head than on here, but I'm pretty sure lol.

That's even better with showing you all his awake time.

Not sure why you would be getting such bad battery life. I was just trying to help and see if there was anything you could pick up from me that would help with you.

It is in fact a bug. Here is a bug report in Google's bug tracker. Here's another. There's also a very long XDA thread that explains what the Android OS bug actually is, and how it works.
If the lines are proportional, then Android OS is using more power than 2 hours of display time, and I've gone as high as 5 hours and 30 minutes. I've had times when 4 hours of screen time is still less than Android OS. What? That makes no sense.
From the XDA thread:
Same network, same location, same signal strength, same ROM (Changing my font maybe fixed it....) , same wakelocks between them, same background apps running. Not even 5 minutes screen time on the two. The only difference with .14 patched kernels I'm experiencing is that it's not showing up anymore in the stats, but it drains just as much as in the right screen, showing the same CPU state behavior. It's also happening less often, and many say it's not happening at all anymore, but how would they know it it's hidden now?
Click to expand...
Click to collapse
Before that were two screenshots. One of them showed a minimal Android OS bar, while the other had it at 95%. The only difference was the patched kernel. This. Is. A. Bug. Period. High Android OS usage means absolutely nothing. Even after tracking down wakelocks, it will be high or low pretty much at random. Sometimes this is a legit stuck suspend, in which case rebooting is the only fix. Other times, it's just the bad profile. There's no way to know unless you study CPU spy, better battery stats, and possibly Watchdog.
In any case, read that XDA thread that explains what Android OS is. It has very little to do with how much screen time you have.

wow, thats crazy.

I'm not trying to bash you or say I get bad battery life. I just don't see someone who is taking his or her phone out every 10mins getting emails, and calls, social updates, background syncing is going to get 10hours of battery with just about 95% left.
Maybe if all you do is check emails and take 15 min calls and put your phone back into sleep mode you can probly get that. But even then. I can't say real world usage = 10hr with 95% left. only if you have a extended battery on
From my Samsung GS2 E4GT

This is with an hour of screen time. Admittedly, that's less than half my normal usage, but I was working on my book on the train instead of reading reddit. I'd normally be in the 50's by now with about 2.5 hours of screen time.
Way better than my Eris.

i've found that turning off facebook and twitter sync alone have greatly improved battery life. enough where i dont really have to diable anything else.

Battery percentage setting issues

Hi again,
Just about to give up on this tablet when I noticed that it seems to be the battery percentage setting that is causing my charging and discharging issues.
With the setting turned on and the percentage visible, the battery seems to discharge and charge oddly, and also the percentage shown does not reflect the amount shown on the battery icon, or at least it rarely does, but it varies.
With the percentage setting off, the discharge seems much slower and predictable.
If you have a p600, could you possibly try this for me with and without and see if it matches with my findings?
Thanks.

I'm having very odd battery issues myself. I'll give this a try and see if it improves for me.

Thanks for the reply. I'm not using any battery app, just the one that comes with the stock tablet.
I think I did encounter the same thing as you, and also unplugging at 100%, then taking it upstairs and looking and it was 96% or so, and then after a restart, it was 100% again. Very odd, but it doesn't do it for me unless the percentage setting is enabled.

No i suspect my device might have some deeper issue. I can drain the battery from 100% to 0 in an hour of playing games but if i turn off the note and turn it back on, it'll be back at 60% or whatever it's actual battery level is. I can rinse and repeat and slowly get it down to 0. Either way the battery drains much quicker than it should. It could probably only last 6 hours of screen on time with very light usage. I might need to get motherboard or battery replaced.
I am still hoping that its a software glitch and something like this could fix it.

I've had it since it was released in october or november and the battery life used to be good and last 10+ hours and probably 5-6 hours while playing games. Not sure what happened in between. It has taken a few very light drops with no visible damage and i did break (bend) a charge with it in the tablet but the charging port seems normal and still works fine.

Just checked with battery % off for 30 mins and battery dropped 4% which is normal.

Is your unit still rooted????? If so have you tried removing root and installing the most current factory rom.
Have you seen this post "Longer Battery Life (or How You're Being Robbed!)"
It may help some that are having issue with battery drainage but after seeing your post #36 in the BATTERY posting .... I'm leaning towards a cracked or damaged board from the few drops you talked about.

I've tried unrooting and odined back to a factory rom, also cleared my SD cards, nothing helped so i'm back to being rooted for now. I've done a lot of the tweaks to improve battery life but whenever I play games, it just drains like crazy even with minimum brightness. The drops were very very minor, like from 1 foot onto carpet and with a case so I doubt that it was the cause but I guess theres always a chance.
I'm still wondering if I should just live with terrible battery life and stay tethered to a charger or risk sending it back to samsung and having them find out it was rooted and overcharging me for repair. And I love the device so much, I don't know if I'd want to give it up for a week or two.

Thanks :good:
So, I wonder which is correct, the icon or the percentage? If the percentage is right, my tablet is faulty. If the icon is right, it would seem to be ok.
And all these reviews and people that get 10-12 hours, I guess they went by the icon?

The percentage gives a more accurate time I guess.
But people and myself use the "Screen on time" as the usage data.

Was doing ok last night and then came here and the battery took a dive. Went and grabbed adblock for firefox and ghostery and ghostery was reporting 65 trackers on this site. Also the malware popups were becoming ridiculous and they only happened here. Going to do a factory reset and not come come here tonight, see if that helps anything.
I did do a bit of a search regarding the malware here, and it was being reported as early as last june it seems.

another battery life issue

I'm sure this question has been asked before. But I'm coming from an iPhone so Neff help with this.
As soon as I start using the phone in the morning when it's connected to WiFi. Within a second of using it or 2 minutes if we're being realistic. The phone loses 2%. Is this normal ? Coming from an iPhone where 100% would last at least 20-30 mjnutes. I can't seem to find anything draining my phone either !

I think a longer observation period (a full day / through the night) will give a better idea of how your battery performs. Use the default power settings or other batter monitoring application like GSam Battery Monitor and compare it against other users here.

Well that's 3.5 hours of screen on time and you're at 45%. That doesn't look bad to me.

Got nearly 20 hours off charge with moderate usage throughout the day with a mixture of WiFi and 4G. Turning power saver at 50. Phone had 33 per cent left by end of day.

Urban myths and old wives tales. Cycling the battery doesn't "improve" battery life on a Li ion battery. What you are possibly doing is making the battery meter more accurate (placement of the "high" and "low" flags that correlate voltage with "full" and "empty"). But its just a means of measurement, and this doesn't affect the battery life itself. Meaning, it doesn't "improve" battery life any more than messing with the fuel gauge in your car would increase or decrease the amount of gas in the tank.

This doesn't mean anything. The battery % is just an estimation based on battery voltage remaining versus how the phone "thinks" you are going to use it. Comparing 98% on Android versus 100% on iOS is apples to oranges. There is no standard for this, or reason to believe they are in anyway comparable.
As previously noted, 3.5 hours screen-on time with 55% drain (45% remaining) is very normal, even good. A lot of things affect battery life, not least of which is how you use your phone, and cell reception in your area. You will see a wide array of variance in the battery life people get. And since yours seems actually pretty good, I wouldn't worry about it.

Thanks [emoji3] it was actually &37 percent but that's still pretty good with the battery save g options available I should be able to exceed a full day in the event of an unplanned night out !

To be fair, I feel like Apple designs their phone where their first 20% will take forever to drop but as soon as it passed that point it falls to 0. And yes I've seen it shut down at 10, turned it back on it's at 2. Where as this phone's last 15% seems to take forever to drop.

id say thats pretty good life outta the battery. the more you use it the more its gonna drain. and those getting like 6 hours of screen on time are strictly on wifi at an office or something. if your out roaming with LTE and the such your probably not going to get 6 hours...

Intense usage on 4g with lots of camera usage and uploads music and a few phone calls. So far so good! Had more than enough when I got home to leave without changing I case I needed it

I feel the M8, and my past Android phones take a disproportionate amount of time to drop the first few % as well. Maybe not as much as what you are mentioning for the iPhone (couldn't personally comment). May have to do with the saturation charge that occurs when the battery nears full (in fact, you should actually leave your phone on charge for some time after it says full).
Also, the battery meter on any phone is far from accurate. It often can't really be trusted with be within 5 or even 10%. So that would explain why you saw it "jump" down 8%.

Yeah my point was that all these phones' measure battery differently and not exactly accurate so you shouldn't compare Apple to oranges. Oh and the jump in percentages was referring to the iPhones. If anything Android tends to jump up when turned back on lol.

Can anyone give their battery life numbers please?

What battery figures are you guys getting? Sot, type of usage, installed apps etc. Thanks.

Used the phone almost 12 hours exactly (11h 59m 26s) and at 75% battery.
SOT - 1h 24m 19s

Thanks for your reply. So that would translate to approximately 6 hours sot I guess?
Anyone else have some numbers please?

It seems like I'll get 4-6 hours of SOT with two sim cards and a bluetooth smartwatch constantly connected. I've been more concerned with measuring standby time than SOT though. Doing a pure standby test, the phone drains just under 1% per hour as far as I can tell... about 6% in 7 hours.
Having left the phone alone, charged to 100%, I'm at 91% after 12 hours, with 5 minutes of SOT. This is on latest EU rom, which is based off of the MIUI 9 developer version released on Sept 22.
Hopefully standby improves with future updates, but generally I've found with two SIMs, standby times just can't be very good on any phone.

After doing my best to drain this beast, I ran the phone 6 hours as a hotspot, along with constant fiddling with the phone because the device is so sweet. Once I got home, I fired up my Slingbox app, and set the brightness to max, and let the phone stream 1080p via 4G until the device died, ~4 hours later.
I push my devices to the limit daily, and have held onto a s6 edge + for so long because the battery recharges so fast, and lasts quite long. However, I still use a Zerolemon case with a 8500mAh battery, because i tether so much. I've also gone through the Pixel XL 128, Xperia Z5 Premium, s8+, and was unimpressed by the battery life when tethering, and playing slingbox.
The Mi Mix 2 is hands down my new favorite phone. I installed playstore, and used the Package disabler app that was only samsung exclusive, to take admin control, and remove the chinese apps. The only thing I am left trying to figure out, is getting sam pay to work from my Gear s3.
Cheers.

Excellent. Thanks for the information. I was considering the Mate 9 until I saw the prices and the leaked pics. But it's the Mix2 I've always wanted with the smaller battery being the only question mark. Looks like battery life won't be a problem at all.

Battery life gets closer to the original mix than I expected, Snapdragon 835 and reduced screen size do help compensate more for the battery reduction than I thought it would. I'm on wifi at home but I'm always tinkering with the phone, browsing, reading books, etc etc. I plug it in every day but since I initially charged it to full, I haven't gotten the battery down to 50%. Even if I forget to plug it in after I come home, the phone "rewards" you for leaving it alone. I'm sure as I use more features and apps (shopping for a smartwatch) I'll drain it quicker. Not allowed to use phone at work, I can only do quick tasks for a few seconds at a time. Snapdragon 835's strength seems to be power usage while idling. Again, as I add more apps and features and on days when I'm bombarded by notifications, it will drain faster. I was out of touch with smartphone progress for the past 3 years, I appreciate quick charging more than I expected. I just got up during typing this post to check on the phone. I haven't even moved the charger to the bedroom and that's a good sign. I woke up, phone was at 55%, plugged it in, made coffee, browsed the internet, started posting here and battery is back to 97%.

That's impressive. I'm going to be ordering in the next few weeks. I'm leaning towards the 64gb model as I never use above 25gb on my phones thanks to Google Photos.

I'm really impressed with the Mix 2. MIUI 9 Beta. Battery optimization as well as MIUI Optimization turned off as well no battery saver mode used.
Take a look at the remaining percentage compared to screen on time.
Lots of reading news, YouTube, playing music by streaming, taking photos. This charge primarily on wifi, 90 minutes 4G.
Standby is also very very good indeed. Went to bed last night with 43 procent left. After 7 hours down to 39.

As written in the my first post it's the MIUI 9 Beta.
And it looks like you are right. There is around 10% difference after all.

Around 50 minutes/10%is pretty solid though.
