Develop Bugs

I've been doubting myself too much

to the point where I'm thinking of returning my Galaxy Nexus. The phone is beautiful and slick but I can't deal with the battery life. I'm especially worried for when I go back to my University next week because I'm not sure if the phone would last while I'm going from class to class from 9 AM to 5 PM everyday and most rooms having low to no reception.
Before this phone I had the HTC Thunderbolt with the extended battery and it could last me the whole day while I was going from class to class and under heavy and constan usage (to the point where I never had to bother monitering it or caring about the battery). I would have auto-brightness on, GPS, Google Latitude, use Facebook app freeling, have Google+ uploading my pics as soon as they were taken, use Pulse, and be ALWAYS connected to 4G without worrying about the battery life.
Now with the Galaxy Nexus I'm forced to turn down my brightness, turn off GPS, turn off Latitude (you can see where this is going. Pretty much opposite of Thunderbolt), uninstall Facebook and disable Google+, minimize my usage, and use Wifi whenever possible to get through a few hours. I even uninstalled Google Voice today to see if that makes any difference. Really? Why am I crippling my smartphone? Why should I have to turn off 4G on a 4G phone to save battery?
I'm obviously an idiot for comparing a Thunderbolt that has an extended battery (2,750 mAh) with the Galaxy Nexus that has a normal battery (1,850 mAh). It's also my fault for trying to believe that battery technology would improve in about a year especially after the horrible battery life from the Thunderbolt; I thought that people would learn from other's mistakes. I thought that the Galaxy Nexus, Google's new and precious baby, would fix the woes from previous phones.
I've been following a ton of forums to find out if there's a fix and I've done a bunch of stuff (disable Google+, uninstall Facebook, etc) but there's barely a difference. Some people are suggesting that an update will come along to fix the battery but I'm tired of hearing that excuse. A software fix will only do so much. And 4.0.3 has been announced for a quite a while from Google. Why hasn't this phone been update to 4.0.3? Why did Google halt it from the Nexus S? Is there something that's running down the battery even more with that update? I don't want to go off topic but I just hate being kept in the dark and not understanding what is going on.
Here I am now typing this as I'm looking at my Thunderbolt while it charges. I'm planning on trying out a few ICS ROMs to see how they go. I'm just tired of second guessing myself. The Galaxy Nexus is a beautiful device, both software and hardware wise; the camera may not be the best but I love it's speed and ICS is just sleek as F. But I can't fully enjoy the phone with the mediocre battery life that I am getting.

I suggest stock 4.0.2 with ogdobber's jamesbond kernel which only has undervolt open and the gpu oc'ed. Probably need to turn off lte and stick to the CDMA. 3g CDMA isn't fast but it is passable and battery efficient.

even if battery tech does drastically increase 1750 mah will ALWAYS still be 1750mah it may take up less space or create less heat.. Mah is a measurement of milliamperes per hour

Try Paul O'Brien's excellent MoDaCo ROM - very impressive battery life and for $9 you get access to the kitchen. There's an update due today which will fix a flaky call issue.
Alternatively, hang on for 4.0.3 which is likely to bring some decent battery life improvements and bug fixes (though wouldn't surprise me if it's out for the Galaxy S2 first). I used to get 2-3 days of heavy use from my SGS2, get one of those and wait for ICS if you want better battery.
And a last alternatively... shove one of these in your bag:

If your in places with no reception, put the thing in airplace mode or disable mobile data.
This phone gives me the best battery life vs my last 4 phones,... HTC hero, htc evo, Nexus s, and htc evo 3d...

Get an external battery. Since you are in uni I suppose you will be carrying around a bag anyway so it won't be too inconvenient to lug around. Just leave your phone charging during lunch and it should last the rest if the afternoon.

Go into your sstem/app folder and take off apps that you don't use. EVERYTHING you don't use. if you take a trip to that folder you're gonna see a lot of **** that you didn't know was there.
Do some cleaning and you should be fine with your normal usage. Also, try to flash a kernel so you can customize the governors and allow the phone to sleep more efficiently.
Coming from a thunderbolt, you should know how horrible battery life is for ANY stock android device...
There's no need to gimp your smartphone. I fluffing hate it when people say "just disable 4g, 3g, take auto-sync off, turn brightness all the way down, and only surf the web with wifi"
WHAT? WHY THE **** DID I BUY A 4G SMARTPHONE THEN IF I'M ONLY GONNA USE IT AS JUST A PHONE?

Also to put it in context...I'm using the epic 4g and I still have the stock 1500 mAh battery and the only time I lasted more than 4 hours on stock without having to charge was with a gngerbread leak.
But after a couple days of devs getting dirty and taking the time to clean up, your battery should last exponentially longer since people will have figured out what exactly drains the batter and how to stop it.
On the epic, it was the DRM. **** always ran in the background, then someone discovered it and about a month later it became so irrelevant since all the devs knew what code to get the drm to stfu until you needed it

Lol lay off the nerd 'roids. It like leaving all the lights on and air conditioning in your house and wondering why the bill is so high. It's like a lot of people are expecting their smartphone to automatically be efficient. Get a bigger gas tank if you need to run a marathon. Otherwise sprint efficiently with what you have.

Battery lasts me all day on the GSM version.
Folks, powering an extra radio uses extra power.
Moreover, the longer your data connection stays active, the longer your radio is active which is an even bigger drain. Since the LTE Gnexus devices are powering 2 radios (CDMA *and* LTE) simultaneously, and the second radio isn't as efficient as the standard radio that's part of the SoC package, this means that you need to ration your data usage if you want your battery to last.
Again, on the GSM version this isn't an issue because the radio is built into the SoC from the ground up, as well as it being only a single active radio at a time (GSM *or* UMTS/HSPA).
Software updates won't change that. It's a matter of physics. The LTE version may see some improvements here and there, but no software will counteract the effects of having to power 2 radios constantly.

Lol its definitely not like that. Its more like buying a new eco lightbulb that you use just like your old lightbulb but your bill is $80 more. Wut? LOL
But nah my epic 4g lasts me the whole day with 4g on (no access to wifi :[ ), auto-sync for gmail (i don't use facebook so its always the first app to go), blah blah blah. The only time battery is a problem is if I'm in a no sprint zone and forget to make my phone roam. Other than that, its used as a smartphone with 3+ hours of screen on time (voodoo color allowsyou to edit the gamm values and what not so its able to sip less power for the same brightness if that makes sense)
Seriously, root your phone and if stock is your thing, just install a custom kernel. Kernels handle the voltages and frequencies andhow your phone interacts with certain things so a custom kernel will almost ALWAYS have been optimized over stock. You will probably see a muc better result if you flash a ROM and Kernel, simply because custom roms are made to work without all the extra **** running in the background that no one wants

Just to clarify, make sure you KNOW what you're deleting and make backups anyway, just in case something you remove from there causes issues with another application that expects it to be there. Sure, you can remove a lot (if not most) of things from system/app without harm, but don't just go deleting random things unless you are SURE there will not be side effects.

You can have good battery life, of course
Here is mine, all stocks, not-rooted, not-unlocked, 4.0.1, yakju.
Using EXTENDED Battery 2000 mAH, GSM version.
Stand by 2 days and 7 hours, screen on time was 3 hours and 18 minutes.
It still has about 17% battery life, which could easily translate to 1 hour or so screen on time

Your words were to delete EVERYTHING in system/app that you don't use. I'm not trying to pick an argument here, but I just like to clarify, because what may be common sense to some people may not be to another. Not even necessarily the OP, but others that come across the thread in the future.

[LTE]New GNexus owner - thoughts and (battery) issues

Coming from AT&T and a carrier branded GSII (i777) followed by an international note (N7000), I'm evaluating Verizon and the galaxy note. If the service is better, I'll jump from AT&T... otherwise, I'll go back to AT&T and my note.
However, this isn't about the service - but about the phone. I understand that some of this stuff might be CDMA/LTE specific (hence the reason for the title)
The biggest thing I see as an issue with this phone (so far) is the (stock) battery life. It completely sucks. 6% battery drain an hour with the screen on only 3 minutes? That's beyond horrible. I don't have anything loaded on here thats a "known" wakelock issue (such as skype, facebook, etc.) As a matter of fact, it's configured (mostly) the same as my GSII and GNote, so it's easy to notice the horrid battery drain. In the same 1 hour period, syncing the exact same exchange server (push email) account, but with 10 minutes display on time, the gnote drained 1%. (I realize that the note has a much larger battery [and display to drain it], but it's useful to compare anyway.)
If I actually use the gnote (display on), the battery drops much faster. With actual light usage (such as for reading email), I get about 6-8 hours of battery life total. If I use it heavily, I'll be recharging so often I might as well hard wire to a wall outlet.
I'm using the AOKP (m4) firmware - first with the kernel it comes with, and I installed the latest STABLE "lean" kernel last night hoping to resolve the battery drain (so far, it's not.)
BetterBatteryStats isn't showing me anything unusual other than a "modem_usb_suspend_block" kernel wakelock (5 min of 1 hour)
Is this what verizon galaxy nexus users typically deal with? Is the battery life on this device really THAT horrible?
Did I miss a "FABQ" (frequently asked battery questions) thread somewhere? Surely the "google experience" isn't only a quickie...
Thanks
Gary

Battery drain while off should be between 1-5% per hour (From what I have noticed). Try enabling AOKP battery saver which will drop from 4G to 3G while the screen is off which should help with the screen off battery.

disable LTE, and you'll watch your battery life double.
Or just return the Verizon version and buy the GSM version instead.

Drain should be 1-5/hr with 4G enabled or disabled?
I'm kind of in shock at the battery drain on this thing. I'm pretty fluent with android devices, and I generally avoid any of the normal battery blackholes (such as social networking, skype, etc) I also know how to PROPERLY configure exchange so it doesn't drain battery/data. (make sure the IP number of the exchange server doesn't change when switching to/from internal wifi networks.)
However, this is my first experience with using a verizon android device - and first with LTE. My SGSII (GSM) could get 2days on a charge (2%/hr was normal when not on wifi.) and the Note (international version) could go for 3 days on a single charge.
With the LTE GNexus, 6%/hr drain with nearly no usage would give me about 15 hours of usage before 10% turn off. If I actually want to read my email messages or make a phone call (it IS a phone, you know), I might drop to less than 12 hours. I can't imagine that this is normal - or that google, verizon and samsung would endorse something like that.
(Okay, maybe samsung would... they seem to be going downhill lately.)
Surely I'm doing something wrong and the phone doesn't suck this badly. (I really hope I'm doing something wrong, as it will completely destroy my opinion of google if a "google experience" is a phone that lasts only 15 hours/charge when just left in standby.)
Thanks

the problem with battery life is LTE... its a double edged sword: you get insane speeds at the cost of battery life. every CDMA phone takes a huge hit when LTE is enabled which i think is the reason that apple has been reluctant to release an LTE enabled iphone thus far until the tech matures. im using a GSM gnex (i9250) and i can use the phone all day and still be over 30-40% at the end of the day

even with franco kernel 121 on my miui gn, i still need to charge 3 times a day... this is android.

its not android, its LTE.. as you can see both of you are on verizon
my older HTC sensation actually got over 2 days of constant use easily (dual core snapdragon running ICS) since it was GSM.. my galaxy nexus while not getting 2 days, easily gets 1 day no problem on GSM
AFAIK there is no LTE iphone which is why you see on average the insane battery life on those devices

I've made the change mentioned in another reply (turn off LTE when the screen turns off.) I'm charging the phone back up and will see how things go then.
With both wifi and LTE disabled, I won't be happy with drain higher than 2%/hr (assuming the screen stays off and I don't get a massive influx of email.)
For the person who said that's just the android is, you are VERY wrong. As I mentioned earlier, I'd get 2 days on a AT&T branded galaxy SII (i777) and I get 3 days on my galaxy note (international version.)

I don't know, it has to be something with your apps or your signal. I mean, 6% is fairly high in my opinion, even on LTE. I never turn LTE off unless I'm out of town (which is hardly ever). I usually get anywhere between a total of 15-20 hours of total time, and 2-3 hours of screen-on time. This is with auto brightness enabled, no GPS, no BT, just LTE. All my notifications are push as well. Make sure your signal is always a light yellow-green color (in the battery settings menu), otherwise that will definitely be the big battery eater. May I suggest trying different radios, or flashing a 4.0.4 rom? I think the new radios/4.0.4 roms have substantially increased my total and screen on time.

Which kernel are you using? Which radios?
I just updated my radios to use the 4.0.2 for CDMA and 4.0.3 for LTE. Not sure if that will help battery life, but my LTE d/l speeds jumped from about 6mbps to 24mbps (as reported by the speedtest.net app.)

No reason to turn your GPS off. It only gets used when needed so will not hurt you battery.

On lte with everything else disabled, sync disabled, cm9 with lean kernel 3.1.0exp1, I get just about a day of usage with about 2 .5 hours of screen life, I think it is possible o get decent battery life on lte.
Sent from my Galaxy Nexus using XDA

removing the "my verizon" app (and the associated "data usage" widget) seems to have helped the battery a bit. Now at about 4%/hr on LTE with BT/Wifi off, GPS on (but unused.) Perhaps changing the LTE radio to 4.0.3 also helped. Using that same "lean" kernel that seems to be popular in this thread... whatever he has flagged as "stable" as of this post.
The only thing that runs beyond exchange syncing is beautiful widgets (home screen with hourly weather and time.) No other widgets, weather turned off in AOKP.
Take care

Post some pictures of your battery stats so we can see whats going on.
People usually complain about battery life when the first get a phone because they are using it non-stop, downloading apps, etc. If you go from 100% to 0% in 1.5 hours there is cause for concern.

Looks like your screen was on the majority of the time. People have reported between 2.5-4 hours of screen time from 100-0% with the LTE version. So, to me, it seems normal, especially if you are gaming or browsing during that time.

Battery life blows on the Verizon version. I have tried all ROM's and kernels. I have LTE off, no syncing at all. GPS off, etc...
This is on par with the EVO 4G crappy battery life.
I get maybe 6 - 7 hours battery life on a weekday. And a full day + on weekends with light use and WiFi.
Weekdays I make 30-40 phone calls...send 100 texts...read and send couple dozen emails...surf the web...use navigation once per day...doing all that this phone dies fast.

Curious, was the battery life any better or worse when it was stock?

I forked out the money and bought the Seidio extended battery along with their protective case. It definitely makes life better. I live in a non-LTE area, so I tend to just keep it off unless I'm travelling somewhere.
But I have the AOKP ROM, the Franco nightly kernel, you can use various apps to have it turn off one of the cores when your phone's screen is off, and even underclock it. I don't use Juice Defender, but that will help when the screen is off. I wouldn't mind an app that knocked you down to 2g when the screen was off (less battery consumption I've heard).
I am about to install this radio: http://forum.xda-developers.com/showthread.php?t=1469687
Not sure if it'll handle my connections better or save any battery or not, but if you live in an LTE area, it's probably a must-have.

Nobody really knows why. Even with lte off the Verizon nexus gets horrendous battery compared to the GSM version. Its a mystery.

No mystery. GSM has always had better battery life than CDMA. And LTE is even worse.

i use AOSP 4.0.4 from birdman and franco's milestone 2 kernel. after a few days and reboots 1x per day, the phone battery lasts so much longer. im getting like 25% more life out of it. i have the extendedn 2100 mah battery and some days now, im going to sleep with the battery at 40 - 60% instead of the normal 4%.

Yeah but we're talking about the GSM version on 3g which is wcdma air interface, which has the same performance as cdma since they both are near identical.
If we were talking about the phone on edge tdma then yes that battery life is much longer.

There's a post somewhere around about improving battery life (think it's linked inside either the Android HD ROM or Codename Android ROM thread)... but basically in that post - it talks about wiping your battery stats file at 100% so the phone has a proper idea of what 100% is.
When you flash, your phone assumes whatever current charge you're at is the 100% mark.
You should be at 4200mV(give or take) at 100% battery (at least this is true for GSM, I'm not familiar enough with the LTE version to know if the value is different). If it's lower, you're not actually fully charging your battery and that's why your battery life is terrible.
Might be worth a check at least to see what you're getting for 100%, and then trying to update the batterystats file by the method in that thread. I'll see if I can dig it up.

It really doesn't if LTE is off.
Worse sure, but not on the order of magnitude to consider it horrendous.
My wife is on stock IMM30B, not rooted gets an easy day out of the battery. A day and a half if she uses it less. I have LTE turned off at all times for her.
My battery sucks, but considering I am constantly rebooting, flashing, and overclocking, that is of no shock.

Im concerned..Please Help

Hey guys...im thinking of buying this awesome phone but there is one concern which is the battery life of this phone, i have searched many places, read many reviews, all were mixed. So i decided to open a thread here and ask the actual users of this phone about the battery.
please report how many hours you get wth a single charge and what activities you perform..
im not a very heavy user, but use my wifi from time to time, dont use 3g at ALL, one hour of games. mostly browsing stuff, checking mails,twitter,gplus,news and all.
sorry for making a new thread for this
Thanks in advance

You can't measure battery like that, each user has a unique way of using their phone.
With the usage you describe it will last you until you're back at a charger, at least 12 hrs with 2-3 hrs screen time.

I would consider myself a heavy user. I watch about an hour of video every day via YouTube and have wifi and data always enabled. I do have to say I run a custom rom and kernel and that has significantly improved battery life since I bought it. I usually finish a days use with about 20-40% before charging again. It's hard to say since everyone uses their phones very differently, but compared to other android phones I have owned this is by no means a battery whore (any more).

Battery life for me is worse than any Android device I've ever owned (see my signature), by far, even with the same amount of usage.
Best ever was my UV/UC Nexus One. I miss that metallic masterpiece.

What are you using. Iv installed a few roms and kernels and my battery is still horrible. With little use too! Im in school all day where I get a perfect 4g signal. Yet the phone still drains battery.

i know we cant measure the battery life like that, and its not my first android devices, i have used htc wildfire, and gakaxy i9003.
i was asking compared to others is the battery satisfying ?

You're looking at 3-4 hours of screen on time per day on average.
I've had it last for almost 3 days (very minimal use) or 6 hours (very heavy use, 5hrs 16mins screen on time)
Depends how you use it.
And to ryjabo, the battery life in this is better than the nexus s. Definitely.

The GSM version gets very good battery, especially if you are not a heavy user. The Verizon sprint version gets bad battery. I go 8 hours and have 70% left with 1 hour display time. This phone idles very very well. On wifi all day is even better.

Well for starters I have a gsm phone, not lte and I'm sure that helps a lot with battery. Apart from that I'm on cm9s latest build with Francos latest nightly.

I have the Google Play GSM version, rooted but with no special power tweaks. Yesterday I didn't use it very heavily (< 1 hour screen on), and last night I had 82% remaining after 16.5 hours. That was with wi-fi on all day. It definitely seems like the screen is the most power-hungry component, and it typically accounts for about 50% of my battery usage.

You should expect mixed reviews for this phone. This phone targets developers. Developers know all the intricates of a device and benchmark it against other hardware.
The Gnex is on par with the Photon 4G and has a better battery life than the EPIC 4G. (for me). I stick to stock roms and only change the kernel.

Yeah the fact that you're even connected to 4g all day is probably why your battery life sucks. I always stay on 3g when im not on WiFi unless i need to download something or do some browsing or what not.

Is the Galaxy Nexus battery really that bad?

I just got the Samsung Galaxy S3. So far I love it..... Except for the fact it has the locked bootloader. All my Androids have had full custom roms. I just like the user experience of AOSP much better.
I am an average or below average power user. Yesterday I took my SGS3 off the charger at 6am and with above average use all day (I was setting all my email and apps up and a few video google talk chats), and was able to make it till 11pm before the device shutdown.
With the SGS3 having a locked bootloader, and not knowing if there will be a workaround to get me a AOSP rom running, I was thinking about returning this device and getting a Samsung Galaxy Nexus.
Is the battery life really as bad as I am reading?
I am north of Boston and not in a 4G market yet, and even if I was I would most likely shut 4G off for the most part.
Should I hold out in hopes of a bootloader unlock workaround for the SGS3?
Thanks for any responses.

I'm content with the battery. One charge gets me through the day with what I do and want to do. When I'm home, I always have a charger to use so I only need the battery to last 8 hours.

I have the GSM model and I can easily do two days with a charge. In areas with bad reception this is reduced. However, I still would get 32 hours without a problem.

As long as you don't 4G whore all day, a full day is easy.

I'm a heavy user. I average 4 to 5 hours screen on time with ease. Phone last from 6 am to 11 pm with juice left still if I cut back to 2 to 3 hours screen on time.

If battery life is important to you then check out the Power Saving mode on the GS3. You can activate in Settings or in the Notification Drop-down. Among other things it downclocks both the CPU and GPU. The phone feels noticably slower in some tasks but it can really stretch out the battery if that's what you care about.

Would I get rid of an SIII for a Nexus? I don't think I would. I love my Nexus and I love the fact that I'm already running JB, but the SIII is one nice phone.
As far as battery life, just the other day I had done 12 hours and it was down to 59% on my GSM Nexus. That was probably a little bit less activity than I normally do but still fairly normal. No video calls or anything like that though. But even with that, for me I've always found that I can get great batteries and chargers from Amazon for cheap and I always carry an extra battery with me just in case. I have one in my bag (gadget freak so I have my gadgets bag), one in my car, one at work. They hold a charge for a very long time too so it's not like I have to be charging them all the time.
What I haven't been able to easily find for the GSM Nexus is spare original batteries. I could easily find those in Amazon for the CDMA one but not the GSM. I like using my NFC and the spare batteries I have do not have NFC

you easily make one day. my average use is 1.5, sometimes above. i have never felt its consumption is weak or bad. if you can, get nexus. i wouldnt wait for anything software related down there in the food chain. hardware is not as important as people make it or manufacturers, who sell new devices every week, would wish it to be. google makes phones that withstand a solid 2 year run. try that with an s3. a fully unlocked and cyanogenmod supprted s3 is something else, but still, when key lime is out you'll be haunted again.

This phone has amazing battery, only the galaxy note and the blu studio 5.3(this thing lasts longer than anything) are better in my case

I've had the phone for about 2 weeks now and the battery is not great, but it does seem to perform better after the initial couple weeks. I'm a heavy user, and I have a charger at work and home and it works for me. I love the phone and all the features so it's worth it to me; it's essentially my main computer now.

I get great battery life with this phone, even my girl too and she always has issues with battery. But we did switch from sprint to prepaid with straight tall and monthly 4g

Well, I guess I'll be a downer. I have never been able to get over 8 hours with 2 hours screen on time, tried a few different rom and kernel combos. In my opinion keep the S3.

So long as you're talking about the GSM Galaxy Nexus, OP, the battery is praiseworthy. I bought a GNex from the play store shortly after learning that Samsung would all but abandon the GS2 with regards to future OS updates now that the GS3 is out. Battery is pretty much comparable, I'd say. I managed about 1 day and 10 hours on a charge a few days ago, with 3 hours of screen-on time or so. Some of that time was spent using turn-by-turn navigation as well. I think I put it back on the charger with 8 or 9 percent of the battery left. Friends who have the Verizon Galaxy Nexus report very different results when it comes to battery.

From what I have gathered from the OP he mentions that his SGS3 has a locked bootloader which probably means he has the Verizon version. I would think he wants comparisons to the Verizon/LTE variant of the Galaxy Nexus in terms of battery life, not the GSM version.
The reason I bring this up is that, from what I have read in the forums, the GSM GNex is far better on battery life than the LTE version so it would be an inconsistent comparison.

I've gotten 4.5+ hours of screen time with ease. Bone stock and no attempts to improve battery life at all.
On both the SGS and SGS2 AOSP ROMs (I tried many) got half the battery life that CheeseWiz got.
