Do I have a bad battery or phone? - Samsung Galaxy Nexus

I get 3-4 hours battery life at best I see people saying they get 10 hours I don't see how that is possible? Is my phone a dud or what this is very frustrating. It does the samething On the extended 2100mah battery. I'm running aopk milestone 4 and glados kernel

It looks like you were had screen on for close to 2 hours and made a phone call, albeit short. This is normal battery life for as much as you use the device.

You should try manually sync or set the syncing interval as high as possible.
Wifi always ON doesn't affect the battery life unless your wireless connection is weak/unstable.
Lower your screen's brightness or use Auto Brightness.
Fully charge your phone and let it alone for 2, 3 hours and check how much battery drains. If it drains 3-4% in idle mode, it's normal. Check also if your phone wakes up a lot, maybe some apps are running in the background and they wake your phone up frequently.
Hope it helps.

I used to have really poor battery life and like you wondered how people managed to get the stats I was seeing here.
I recently decided to do a factory reset for a different reason and to my surprise my battery life has improved incredibly. Yesterday I got over 18 hours in total with over 4 hours on screen time. This was with the stock gsm battery. Granted I was using wifi throughout but I was lucky to get 8 hours before the reset, even with wifi. With 3g I'm now getting 14 hours easily with over 3 hours screen time.
My point is if you've never done a factory reset, you may want to give it a go.

It's a bit hard to diagnose the problem based on only a screenshot of your battery stats.
Since your screen is using over 50% of your battery life, my guess is that you just had your screen on for about two hours of the total two hours and forty-five minutes. It's normal to not get more than about two hours of screen time. (Tap on the Screen part of battery stats to get more info on how long the screen was on for.)
In my experience with three Android phones (MyTouch 3G, MyTouch 4G, Galaxy Nexus), all the usual tips to conserve battery life pretty much do nothing to improve battery life: turning off syncing and background data, turning off wireless, don't use widgets, turn off GPS, etc.
Pretty much there are two big battery suckers on Android phones and particularly the Galaxy Nexus--the screen being on and LTE being on. If you dim the screen or just keep it off, you will seriously prolong the battery life. And if you use CDMA only, you will also seriously prolong your phone's battery life.
That said, it's also possible something is wrong with your phone... or your battery. We can't know just from the screenshot you posted.

This looks normal. How much screen on time do you have?

My screen on time is about 1h 30 minutes with WiFi ON.. 3g/sync/gps off auto brightness

GSM nexus battery life WAY better than Verizon Nexus

My two Brothers just picked up the unlocked GSM Nexus off the Play/Market store last week. One has it running on pre-paid T-Mobile, the other on Straight Talk ATT, and their battery life is ****ing unbelievably better than what three of us get on the Verizon Nexus, and we are not using 4G/LTE at all.
Both my Brothers use their phone at work, no Wifi just the 3G signal, and they both text me this week telling me battery life %. Right now after 4+ hours unplugged they both around 85%-90%, not using it except sending several texts and reading websites. And after a work day unplugged for like 10 hours they both have like 70%-75% left.
Now myself, my Wife and buddy have the Verizon Nexus, my Wife barely uses her phone at all, and at lunch time will be at like 70% battery left, and after getting home still unplugged for 10+ hours she's at like 45%. Where my Brothers with same use would be at 70%.
My buddy has the same as my Wife's usage, no WiFi wither, not using phone much and his phone is at like 40% after 12 hours or so. Both of them have 4G/LTE off and GPS off, and no sync on.
I use my phone a lot for work sales calls, and I am in the red by like 4:00pm, I get maybe 7 - 9 hours of use on a busy workday.
My Brother on the GSM T-Mobile, said after 23 hours his phone was at 45% battery life, and that was him using it quite a bit, dozens and dozens of texts, lots of websurfing, tons of e-mails. Our Verizon Nexus would never get that kind of battery life.
It is known. What really matters though is screen on time.

I agree screen time is crucial. But my Wife uses her Verizon Nexus very little at work and by time she comes home is at like 45% battery after about 12 hours or so. My Brother on GSM Nexus after 12 hours and using it a bit more would be at 70% battery.
That is a HUGE difference in battery life with very similar use.

do they work in the same building?
if your wife works in a place with not as good of a signal, i expect her battery to drain faster as the phone is trying to get more signal.
I installed AOKP 5 on her phone last night. Her battery seems much better. Unplugged for 7 hours at 80% battery now. That is a major upgrade. But again she barely uses her phone at all during work, pretty much just sits there. Where my Brother with same use today is at 90%.
I am running CM9, unplugged for 6 hours at 35% battery, but I use my phone a lot during work. Have 2.5 hours screen time. Tons of texts...lots emails...several phone calls....web surfing.

With GSM you can expect around 3 hours screen time and tons of standby time.
The standby time is great, but the screen time is somewhat mediocre to me.
Some days my battery just gets ate and others (like today) I'm having good battery. Usually I'm finding that apps are open in the background even after I hit back to "close" them. So if I keep up on the "Recents" menu and swipe it all away, I see an improvement.
I'm waiting for the MIUI styled "X" that closes ALL recent apps in one strike. Every little bit helps. An older version of Gummy (x.8) I had insane battery life. From 8am-3pm I would still have like 75%. I'm running LiquidSmooth right now and at 3pm I am at 60%. This was with 40 emails and 2 20min calls. No texting today
But LiquidSmooth has more options and is much faster then Gummy, so IMO the small battery difference is a good trade off. Later Gummy versions seems to consume more battery while lacking in the features.
AOKP never ran well for me in either the performance or battery department. Seemed to be laggy AND battery lousy. However I haven't played with it in a few weeks.
I too keep 4G disabled but I also have WiFi on all day (I never turn it off). I also use "Bluetooth On Call" which enables my bluetooth while on a call, so I can use a wireless headset. It automatically disables bluetooth, but I'm sure it consumes more battery then a normal call.
I only have 40minutes of screen ON time too. Mostly quick checks of emails. A few turns of WordFued and DrawSomething. I do work in a dungeon with little/no signal, which I suspect eats it up.

But it depends what you do in that screen time. If you do a lot of gaming and browsing with 3 hours it's great. If you just swipe through the home screen and send a couple text message with 6 hours of screen time, not so great.
A cool test would be to turn on airplane mode and play a movie. I'd be interested to see if it has something to do with programming vs hardware.
Then the same test with 3G.
Both really need to be setup similarly, same wallpaper, apps, etc, to really get a good measure of comparison
This isn't a news flash. Its been pretty well known.

Well, yes and no. Gaming does use more cpu and such than just flipping through your home screens so I see where your coming from and agree to an extent.. But also consider that display is almost always the biggest battery consumer in battery stats, regardless of what you are using it for.
If you switch the 4G off then it will be a different story.

If you really want to compare the battery on all those phones, at the end of the day have your wife, your buddy, your brothers, etc...send you a screen shot of their battery stats. There are so many reasons why your battery life can change, and unless you are following someone all day then you really won't know the full picture.
And yes I usually say screen on time is a better "quick" comparison of battery life. Someone who has a display timeout of 1 min compared to someone with 5 min will have significantly different battery results, even with similar usage.
LTE is a *****.

CDMA radio technology is a bit worse on battery than GSM, I'm betting that's where most of the difference comes from (LTE excluded obviously). With my screen on constantly, I've gone over 5.5 hours of screen on time before on my VZW GNex with about 50% 3G/50% WIFI usage. Again though, that was almost constant screen on from 100% to 0% battery. I've also watched the entirety of LOTR: Return of the King Extended Cut (4:20 minute run time) with my phone while also having 2 or so hours of standby on one charge, but I was in airplane mode for the majority of the movie watching. The screen is absolutely the worst battery killer by leaps and bounds and that will hold true no matter the variant.

True, it always is the biggest battery consumer as anything you do on the phone requires the screen to be on. But it also depends on what kind of users we are. If you use your phone mainly for calling and texting and emails, then 4+ hours of screen time with a total of 16 hours should be good and doable. But if you do a lot of gaming, browsing web, tasks that are heavy then 3hours+ on screen time with a total of 10-12 hours on the chart is pretty good I think.
I agree with a previous poster, screen on time is all that matters. That's why I got an ugly humpbacked Trexcell 3800 battery. Now I get 5 1/2 hours of screen on time on my Verizon GNex. Great when compared to my old time of about 2 hours.

None of us on the Verizon Nexus have 4G on. We all leave LTE off.
So why is the GSM version getting substantially better battery life ? Seems to be at least a 25% difference, if not 1/3rd better battery life on the GSM Nexus.

See my post above. CDMA radios are slightly worse on battery than GSM radios.
Like I said, I've seen 5.5 hours of screen on before once and 4+ many many times. I highly doubt the difference in battery between my VZW Nexus and a GSM Nexus under constant use from 100% charge would be more than +/-5% in either direction so the difference is somewhere in the standby times of the two devices ie. GSM vs. CDMA radio.

Battery...hmm not bad

So I 've been wanting to really test how long my battery could go with minimal use.
This included...
about 45 minutes of 3G tethering
and about 13 hours on 3G. 4G was disabled the whole entire time
As you can see it was idle a lot, but I almost got 2 full days on stock battery. So no complaints.
Part of me feels like if it was not for that 3G tethering maybe I could have got 4 more hours+
Not bad indeed.
Would rather use my phone and have to charge when I get home then leave it in my pocket all day.
Also your wifi was toggled on the whole time... that would have saved some battery.

That sounds pretty dire....are you running at full brightness with Wifi and bluetooth and the GPS on (happens e.g. if you enable GPS for apps and then open Facebook) and no screen timeout while running the camera?
I've had an hour of screen time, and about 9 hours of screen off; I've not had it on to charge at all today, and I'm at 60% battery.
If you go into settings/battery, what else is keeping your phone awake? In other threads, people suggest installing 'Better Battery Stats' (nb, cheap, not free) and posting screen shots of the kernel/partial wakelocks. I can't interpret them myself, but others can...

When I'm at home, it's crap, and I'm about in the same boat as you.

The only complaint I have with this phone is the massive difference between hspa and lte versions in battery life. Other than the razr maxx no late phone has acceptable battery life including the nexus. To get 5-6.5 hours screen time on my nexus versus friends 2.5-3 on an lte version is just crummy. I know some people just have extra batteries but that short of usable battery life is just too much of a hassle for me when I'm out and about. I would be forced to get a huge ugly seidio battery if I needed to move to Verizon. Even with 4g disabled the Verizon/sprint versions don't get the screen time I get with my hspa nexus. I really hope lte radios get more efficient and battery tech gets better. Removable or not, all phones can be made as sleek with a huge battery if manufacturers wanted. The maxx is proof of that.

I am giving my machine a hard time every day. Usually it ****s up after something like 4 hours. That is much better than the old machine I had. However, it is not good enough cause I work for 8 hours. So after the midday break in the canteen there is no more angry birds for me. I think of getting a second machine, one for the morning and one for the afternoon.
Yay, another super 1337 battery thread.

Lol, how's this for on screen time on a stock battery? I just managed to get the screens before I had to charge it up, It's the longest I've gotten with my ROM and kernel combo. Last screen shows it's the ~1800 mAh battery, the third line down reads 35/1750 mAh.
*Edit* Hold the phone, 1400 mAh is stock, right? My 'stock' battery is 1750mAh... How does that work?

Is everyone else getting strange battery drops? When the battery is at 19%, it drops directly to 15%, without going through 18,17,16. Is this happening to you or is my battery screwed up? It's been doing it for weeks now so I don't think it's about lack of battery training
This is with a genuine 2000mah extended battery, minimal use over a long weekend. This is also with emails, facebook etc all polling at 30 min intervals, wifi on but not always connected and screen on auto brightness. I had also conditioned the battery by fully charging and discharging about 5 times when the battery was new.

[Q] Whats your battery life like?

I haven't seen a battery life thread for the AT&T S3, so I'll start one.
Mine is around 13 hours with moderate use. I listen to podcasts for an hour in the morning (commute to work), read Pulse News and Facebook for about an hour at lunch, and listen to another hour of podcasts for the commute back home. By the time I get home, I'm around 13% life. I usually get the battery warning while listening to my podcast. In comparison, my GNex GSM gets 17 hours with the same use pattern. When I get home, I'm usually around 37%. Besides Samsung's and AT&T's bloatware, same apps, no widgets.
All told, I am very disappointed with battery life. I don't believe in underclocking my CPU in or disabling haptic feedback. I use the "Power Saver" mode, but only use the reduced screen power consumption feature (reduces framerates and brightness). WFI is always off (I don't have WIFI at work). I also disabled all of the Motion features. I disabled S-Voice (it monitors for the Hi Galaxy, and disabling also allows for a very responsive Home button).
I calculated my idle battery drain (unplugged when fully charged and not touch it) at around 4.4% per hour. That only gives 22.7 hours of standby! My Galaxy Nexus GSM can go at least 2 days (sometimes I forget to charge it at night on the weekends - also not used the phone).
Is it AT&T's LTE? Is it the Gsiff_daemon process? Is it TouchWiz? Or is it just my phone?
What's your battery life like?
You pretty much hit it right on the head. I had the extended battery from Samsung on my Gnex and could easily get 20 hours with moderate usage.
This phone despite using CM10 or AOKP with the JB kernel I never see battery life that good. I'm in the 14-15 hour range with about 3 hours of screen on time. That's with wifi off, and we don't have LTE yet. All in all, it isn't very good.

Stock? What features do you have turned off? Do you use WIFI exclusively? Do you turn off your data network (LTE/HSPA)? Did you turn off Sync?
I don't use WIFI, and I leave my data on (as it should be - just like I had it on my GNex). I also leave sync on. I understand that using these decrease battery life, but come on... not like this. The GNex faired very well, and it had a smaller battery. Besides LTE and an S4 (and the S4 should be more power efficient), there isn't much different between the GNex and the S3.
If I turn on the screen for 8 hours, there won't be enough for sleep time! It'll just die... if it even makes it to 8 hours...
20+ hrs with multiple accounts syncing at 1 to 2hr intervals, screen on time of average 4hrs. Heavy use. Wifi on all the time.
stock, rooted, debloated, super-aggressive power management I was getting maybe 12 hours with 2 hours screen time.
I saw you didn't believe in underclocking, but I started using Cpu Editor http://forum.xda-developers.com/showthread.php?t=1798765 and am loving it, can do 16 hours and 4 hours of screen time with no problems, will do the trick for me.

You have a faulty radio.
I consistently get 40+ hours off charger with 4-5 hours screen on time with a couple hours of browsing, 3-4 hours of music, texts, an hour of calls or so, playing casual games for another hour.
Stock. No hacks. No root. Disabled all unnecessary carrier and samsung apps and disabled GPS unless i need it. Auto brightness, 2 hours sync for weathereye, flipboard and gmail syncing all the time. I do mostly use Wifi at home because my signal at home is bad and that quickly drains my battery. At work my phone idles for eight hours at a 2-3 % loss with 3G on (i use my old SIM, i do not have an LTE plan, I am on Rogers Wireless).

I just factory reset (wiped data and cache) the phone and installed the apps I need (maybe something was badly configured or something) - did that yesterday night. Charged it up for this morning, and now I got 18 hours and still have 17% left. Screen on time says 1:38 hours.
This is on the same stock rooted and deodexed ROM. No hotboots either, so gsiff_daemon didn't rear it's ugly head.
Also no CPU Sleeper or any of these underclocking apps. I'm happy now, but wondering wtf was causing the problem... and will it happen again (after all, this is only day one).
I'm getting about 13 hours with 5 and a half hours of screen time. Underclocked to 1.2ghz and I have my own screen off profile. Great battery in my opinion

Phone finally died. Just over 19 hours. Heavy use towards the end because I was downloading and installing the rest of my apps from Google Play & Amazon App Store. Was also setting the apps up ( accounts, settings, and notifications...). Final screen on time was about 2 hours.
It's only been two days since I've had the phone, I've gotten about 14 hrs with roughly 3.5 hrs screen on time. I hate when I see people with 2 days off the charger and ridiculous screen on time. If you put the phone in airplane mode and ran just the screen you probably wouldn't last 10 hrs unless it was on low brightness. I had the Razor Maxx and I could get around 30 hrs usage with 4-5 hrs talk and 6 hrs screen on and that's the best battery life I've ever gotten on any phone with real usage.
I would like to get better stand by and more screen time out of this phone without getting an extended battery.

No airplane mode. Cellular connection is always on even during the night. Only difference is at home i have wifi on instead of data.
Flipboard, weathereye and an appsales app syncing every 4 hours. Auto sync for google account and facebook. Automatic brightness. Almost all samsung and Rogers apps disabled (except for myaccount and a couple samsung apps) and motion disabled since i have no use for the gestures apart from being a novelty the first week.
No root. No hacks. I am actually amazed. This is the first android phone that has battery life on par with my iPhone 4 and the unparalleled smoothness. My HTC One X lagged, this never does even with a few apps installed now including games. I look at my iPhone and think "why do i still keep it? It is no longer relevant".
Ive got my UV tweaked just right on my ktoonez kernel and keeping my screen level as low as can be and I'm now practically making it to TWO days battery life! Plug in every second afternoon or evening after moderate use. Occasionally it doesn't last as long. Quite happy now. Oh and that's with this baby cranked to 1.809Ghz! But obviously tweaked to use that under strain otherwise using lower clocks and deep sleeping with 384mhz.
Got a 4200mah extended battery on way and can't wait to see how much I can squeeze out of it too.

Every night when I go to sleep, my flight mode is turned ON. (I sleep around 9-10 hours everyday, so the phone stays on flight mode for 9-10 hours a day)
In the morning, I turn the flight mode OFF.
Bluetooth, GPS both are turned OFF
Screen brightness turned 1/4 brightness
LED notification turned OFF
Also, I have a task killer killing ALL BACKGROUND SERVICES every half hour.
Without killing all the background apps, my RAM usage is around 600-700 MB out of 1.6 GB of RAM
Killing all the background apps brings the RAM usage to around 360 MB of 1.6 GB
Without killing background apps, my battery life is shortened even when the phone is on standby.
Do this, and your battery life is pretty good..

Bad Battery? Bad device?

I've had my Verizon Galaxy Nexus since launch day. I've NEVER been able to get more than 3.5 hours of screen-on time with this thing. But lately it's been even worse. I'm seeing anywhere from an hour to two hours before I have to reach for a charger, usually right around 1.5 hours of screen-on time. It will sleep for a good long while (no wakelocks causing drain that I've found).
I keep sync on for some Google services, like Gmail, but not many. Battery life doesn't really seem to change regardless of using 3G or LTE, nor does wifi seem to improve. When the phone is awake, and the screen is on, the battery just drops like a rock. Literally every time I look at the battery percentage in the status bar, it's dropped another 1-2%, even if I'm not doing anything.
I've run everything from stock 4.0.2 to AOKP JB nightlies (which I'm currently running, with imo's kernel). I've tried practically every ROM/kernel combo out there and never seen an improvement. I've undervolted, underclocked, played with brightness settings, everything I can think of. It's been wiped, the battery has been occasionally cycled, etc, and nothing seems to improve the battery life--it's only gotten worse over time. I did, at one point, have an OEM extended battery, but it wasn't a significant improvement enough for me to get over losing "the hump" so I got rid of it (actually traded it for a Droid X, lol).
So I'm kind of at a loss with this thing. Does the battery really suck this much? The other day, a coworker with a Galaxy S III on Sprint used his phone for over 3 hours of screen-on time (I looked at his battery stats) leaving him at about 35% battery. Mine was also at 35%, with only 1 hour of screen on time. I understand the GS3 gets better battery life in general, but this is getting to the point of being unacceptable.
Not unusual. Big screen = big power requirement. Poor reception (i.e. bad coverage area) saps the battery the quickest, extended screen time on is a close second. Have you tried the extended battery? It adds enough to get well through a work day and commutes if you're not using the phone as a laptop. However if the phone is being used as a laptop, I'd suggest buying an actual laptop, or better yet a tablet. I get 10 hours of steady use out of my Xoom.

Try completely wiping your device through download mode and setting everything back up

The phone doesn't have amazing battery life but what you're describing sounds pretty abnormal. It may be a bad battery.
Yeah seeing as the battery is around 9 months old, I would first try and get another battery and see if that makes a difference. Most batteries dont go bad that quickly but wouldnt be surprised if it did. Worst case you would have an extra battery that you can also keep fully charged as it seems though you have tried most everything you could regarding any software issue.

Pathetic battery life

Running 4.2.2 I get 9h of standby and 1h screen on at the most on a HSPA+ Galaxy Nexus using a OEM 2000mAh extended battery.
I checked wakelocks and there was nothing out of the ordinary. Anyone else getting this bad battery life?
A phone that dies half through the day with light usage is pretty much useless. (I've had to use the 1750, 2000 and the 3800 battery to come through the day.)
Depends if you have any apps syncing a lot or using the radios a lot.
Signal strength plays a big role in battery life as well.

Only Gmail/whatsapp sync a bit, the rest is all turned of/ wifi only. Used gps maybe 20min for google maps ans public transport.
Signal strenght was mostly good with the occasional no signal, 10 min total.
Still, it shouldn't be this bad.

btw im using sprints galaxy nexus running the unofficial xylon, with ak diamond19 kernel, with lte off, and pie controls.
Same here. I'll charge my phone to 100% set it down pick it up 15 minutes later 8-11% battery gone. No GPS, screen turned down, underclocked. I don't get it. I have a Toro also.. Just have to make due I guess till I figure it out.

I just started using a Nexus this week. I came from a RAZR M. The first thing I noticed was the lack of battery life. I found a couple tweaks to help with this issue.
They are: disable network time and date sync, 3g only till you really need to charge through some web browsing, undervolt to 1GHz, and minimal to 383 or so. I flashed the Franco kernel and use the Wheatley governor. Auto brightness was on auto. I also have the 2100mah battery.
I can almost reach 3 hours screen time per charge. I didn't realize that's a feat so I haven't taken a screenshot. My M got around 5 hours screen time. Ugh.. But the Gnex has won me over.

Something is definitely wrong bro... I have the same gsm model with the stock battery. With light usage I can easily go about 36 hours off the charger with 3 hours screen time. Sync with Gapps, Facebook, Keep, Drop box, Google +
Something is Jacked up somewhere...

Use trickster mod to see if your device is deep sleeping. I've had deep sleep issues on 4.2.2

And if you undervolt too much it will actually destroy your battery life

My device is deep sleeping fine, it is really a 3G/data issue. On wifi I can get 4h screen on and days of standby, no problem. But on mobile data my battery just evaporates in thin air.
I think the real problem is the 3G radio power management, that was excellent on 4.0 or 4.1 (never had issues) but on 4.2 it is outrageous.
The thing is, on wifi (home/work/...) I have the possibility to charge my phone. If I'm on HSPA+, I haven't.
My stats on wifi at the moment: 2h standby, 35min screen on 89% left.
Select 2G only if you do not really need 3G or LTE for phone and data! For simple phone calls or texting, the quality is not much different between 2G, 3G or LTE. In fact, in my city, there is more 2G than 3G and LTE transmissions.
It will at lease save you 30% battery.
I can put my phone on 2G only, but than I can't search something when I'm on a call, get delayed sms (really noticable). Not mentioning 2G is a pain in the ass, even for IM and email.
And constantly switching between 2G and 3G is also not a good option for battery life. Turning LTE off on a maguro won't do anything.
It doesn't matter how many features you turn off, battery life will not improve. Your phone will become a dumbphone and it will still die on you. I recommend to stop turning on the screen constantly and use it lightly. The screen used on this device is not efficient at all. I hope the next Nexus greatly improves on battery life or I'm switching to something else.

Android OS is high, BBS will tell you what it is, it's usually a kernel wakelock. Also if you don't use Maps, disable it, because since they brought the offline prefetching, it starts services like mad and runs in BG. Android AOSP has it's own location services and MapView, so you won't loose that.
My phone has become almost unusable after receiving the 4.2.2 update (on Verizon, totally stock phone). Battery has gotten as hot as 113F at times, and I can watch it decrease 1% at a time very quickly...
BBS keeps pointing to Exchange. I removed the account the first day and added it back in and that seemed to have helped initially but now is no longer the case. I haven't wiped the phone in over a year plus so this is my next step.
Is there any way to see what apps were recently updated?
Same battery problems for me (maguro). Not long ago I could use the phone for around 48 hours without charging, and suddenly one day to another it all changed and is drained within 9 - 10 hours. I have tried everything:
- monitoring with betterbatterystats (nothing out of the ordinary),
- tried different roms (including stock 4.0, 4.1),
- tried monitoring with betterbatterystats without any apps installed (disbled google apps to prevent syncing), without wifi / 3g / location services / NFC etcetera, even without sim card. --> No big battery draining wakelocks.
- tried different kernels
- tried new battery
- checked if phone was going into deep sleep (did that fine)
All without any impact, the battery life is still very bad (easily draining 5+ % per hour, if it is on standby all the time).
I'm starting to think it might be a hardware problem, I don't know what to do anymore without sending it back for warranty.
3 initial things I always look for when diagnosing somebody's battery woes:
1) Have you loaded (adb then fastboot) the totally stock nexus images from Google's website? At least for 3 days and no additional apps installed
2) How old and what is the usage of your OEM battery? If you're using a 3rd party battery who knows what will happen
3) What's your signal strength like in your daily travels? Bad signal will eat your battery almost as much as screen time
If you still have bad battery after thinking about those 3 questions then you have a unique situation. Otherwise, your problem might be simpler than it seems
IMO, turning off gps/wifi etc doesn't really help with battery life, at most 1-2%. Usually what causes battery to drain faster is when apps prevent the phone from sleeping, or if they're constantly running in the background.
