3 hour screen time normal?

So basically I've had the nexus for 2 days now, and battery life is bad for my standards. I had the Note for 2 weeks and averaged 6 1/2 hours of screen on time before the battery went dead, that includes browsing mostly on the web and the xda app. The only thing on was data and bluetooth, no wifi. On the nexus, with everything off except data, I only average 3 hour screen time. Is this what other folks are experiencing on their nexus?

I was denied a Nexus last week so waiting until tomorrow now. I have a Rezound atm and on this thing it lasts about 2 - 2 1/2 hours(constant use).
just last night I played a game called Sentinal 3 on it. phone was in CDMA mode(LTE off), bluetooth & wifi disabled, and brightness all the way down. when I started playing the battery was at 93%... played 2 levels, took a break & then the battery was at 34%.
granted, each level took about 20min... but still...

I get about ~4 hours of screen time before my battery is dead. Really depends on what I'm doing, and how spread out those 4 hours are.

I'm getting about 3/12 on a work day. With about 25% left. Which is pretty damn good considering the screen. My gpu is 384 mhz and my undervolt's are 250mv+ for each frequency. This weekend i'm seeing if i can get 5 hours screen time with wifi. I know i can get 4 hours plus already and that was before patching my kernel for upping the gpu and undervolting.

I should have mentioned that those hours I was talking about were spread over 12-14 hours each day. Btw, would changing kernel and ROM improve battery?

Note has pretty much the same screen as the Nexus (exactly the same except 1280x800 vs 1280x720), but a massively larger battery. That will allow higher screen on times.

Mine was 3 hours too over 12 hours. Not 3.5. This is before i patched my kernel for undervolting. Also my workday is strictly cellular data with many high rises so my cellular is constantly switching radios beause of reception and congestion. I am very very pleased with how well it does. My standby drain is ridiculously good. I get about 1% drain an hour at work and about 1% drain every 2-3 hours at home. I still haven't tested light flow because it is not playing nice with ics yet. I'm sure that will affect my drain. I think people's expectations were/are too high for display time. People that are social nuts and have a live ticker feed on their homescreen so they know when their friends are picking their nose should get the s-lcd version of the nexus. Lcd power drain is a lot more linear compared to amoled screens.

Your standby drain makes me so jealous. I am in the same camp as many, seeing about 3-4% drain an hour with the screen off. That's also with Juice Defender shutting down wifi and data when the screen is off. This leads to my screen/total stats ending up around 2/12, which is frustratingly bad given the numbers I know this phone should be capable of.
I've tried 3 different ROMs, 2 different kernels, 2 basebands, multiple battery calibrations and charge/discharge cycles, but things never improve. So annoying.

I'm pretty happy with my nexus's performance.
It depends what you're doing, keeping wifi on seems to be a killer, im assuming that's because it's constantly scanning. I get ~5 hours screen time with 25% left at the end of the day.
I take off charge @ 7.30am
Goes back on charge with 20-25% at about 11pm
I use auto brightness
I listen to internet radio during my commute for about 30minutes each way over 3G, read my rss feeds and regularly using gtalk and gmail throughout the day. I rarely make phone calls.

not true, specifically during standby. Keeping wifi on during standby and keeping sleep policy to always on has dramatically saved my battery life. I too was @ 3-4% an hour when wifi was off. Now I keep it on and I average 1% an hour. 3g/4g radio towers use more juice on standby than does wifi. There is countless articles about this on the web.
I get about 3:30 hours of screen time on a full charge. But I think this question is very relative. For example I could get more screen time if I wasn't streaming 30-45 minutes of music and didn't have 1:30-2:00 hours of voice calls.

Pixels aren't necessarily what matter when talking about battery life. It's important, but since both are pushing, generally, the same number of pixels...it comes down to screen size. Screen size makes a much bigger impact on battery life (nonlinearly).

Horrible battery life with their "extended" battery

I call it "extende" battery because it's 250maH more than the stock, big whoop.
I have maybe 10-15 calls per day. I unplug at 10am and by 4-5PM I am at 14% battery. There is NOTHING running. I even switched to CDMA only from LTE/CDMA and it didn't help much.
Any recommendations? I am about to return it. My HTC Thunderbolt which has the WORST battery life of ANY phone lasts me through the day and that's with Facebook and other notification apps.

Wait for 4.03 and see if that helps. Otherwise, turn down screen brightness, turn off LTE, and get better reception. Also, charge it every chance you get.
Sent from my Galaxy Nexus using xda premium

I can't fix any reception issues. This has horrible reception compared to my Thunderbolt as well which itself was bad with reception.
I have it on 3G only and the screen is already turned down.
I mean no disrespect but if the only option is to wait for a "patch" to fix this I probably should return it.
I paid out of contract price for this phone. $649.99 + 8.1% sales tax.
Don't get me wrong. This phone is blazing fast compared to my Thunderbolt but in the end I may just exchange it for an iPhone 4S which has sucky battery life but I can get through 2-3 days on a single charge.

If you even have to think about getting an iPhone, this phone isn't for you.
Seriously, something is probably wrong with your device. I get no reception issues. Sounds like that is the brunt if your issues.

I would say return the 2100mAh battery at least but don't return the phone. LTE is a huge battery hog as is and with the size of this screen it isn't helping either. I'm anxiously awaiting either Mugen or Seidio to make a decent extended battery for it. There is a generic 'made in China' 3800mAh battery currently circulating around eBay pretty cheap, although I haven't tried it out myself yet.

How long have you been using the extended battery? You have to give it at least a week before making any decisions.

I've had the phone since Monday/Tuesday

You should first compare with the standard battery with the same usage pattern. If the standard battery gives you more time then there's a problem with your extended battery. If the standard battery gives you less time, then the extended battery is okay but you should look at your rom settings instead.

If you're using the phone lightly and losing 85% in 6 hours, then there is a hardware problem. Don't buy into the hype that an OS update is going to fix the problem, it probably won't. I have great battery life on my GN using 4.0.2. I think a lot of people have a hardware defected phone, and are in for a surprise when the OS update launches and doesn't fix the battery issues. The Galaxy S already got 4.0.3, and users are still reporting massive battery drain.

Carry a few batteries or a charger and enjoy.

I have found that the battery life I get with my extended battery is above and beyond anything I would have expected. Use WiFi if it is available for you at work or at home because it's typically faster (unless you have 4G signal and slow wifi) and uses much less power than typical cell radios.

Lol totally a reasonable way to keep your phone functional. Hey, just sew another pocket on your jeans just to hold cellphone batteries, no biggie.

I think battery life varies wildly depending on individual circumstances.
My area has stellar LTE reception, I keep the screen at 30% brightness, and I do light web browsing, RSS viewing, and podcast listening.
With the extended battery, I get anywhere from 9-12 hours before hitting 5% battery. Battery usage typically shows ~50% screen and ~20% Android OS.
Granted, battery life dips significantly when gaming or watching Netflix, which I always do at 100% brightness.

although Nexus S has 4.0.3, the update for Galaxy Nexus will be designed for that specific hardware; thus battery life, performance etc will be completely different.

I have the extended battery, using Roman's ROM and I go to sleep at night with about 25% battery left. I make about 5 calls a day, lasting about 20 minutes each. I surf on the phone a LOT, but am always on wifi when surfing.
I have always found that finding the right ROM with the best battery life (sometimes using different kernals) is a necessity with smartphones.

This is ridiculous. Unplugged for 1 hour and now it's at 44%. Absolutely nothing running. I watched it drop from 46-44%

What is your screen on time? How many apps do you have installed? Are you running stock? Has the phone actually died?
Just because it says its that low doesn't even mean it's that low. Could be an error in reporting. I don't pay much attention to the percent... I go by when my phone actually dies.

Get the iPhone and enjoy the tiny screen and amazingly horrible display. Then enjoy the fact that you can't do anything software related to the iPhone as well. And finally, go wait online for the next iPhone flop like every other fanbois out there and don't bother coming back to visit XDA where people enjoy the most up to date technology and don't waste Thread space by posting more useless threads.

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...

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.
Check out my super 1337 battery savings with a stock battery!!!

I'm lucky to break 2 hours screen time on my GSM phone before I have to recharge. How the hell you guys managing such spectacular battery life?

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.

I can get as much as 10+ screen on time with my Note 3 though 8-9 hours is more normal. That's with -5-6 or so hours of SlingBox/Netflix/HBO GO/YouTube streaming with Web, Note taking and email all day. I've watched whole NFL games with my SlingBox in HD with 40% brightness and still had 55-60% battery left to give you an idea. I run my Note 3 with 25% or so brightness most of the time unless I'm streaming video content. I'm not into a gaming much on my phone though. I don't want the burn in with Amoled displays so I keep my screen low unless i need it up.
I don't know a lot about the G2 but the Note 3 is a beat with battery life. The SS is from a few days ago with 4 episodes of Breaking bad and an hour of the Super Bowl streaming with my SlingBox. Damn GF hauled my ass out of the house for an hour during the SB. That's 5+ hours and still 47% battery left.

Stock battery life = anywhere from a day and a half with 12-16 screen on hours to a full days use with 8-12 hours screen on.
Zero lemon im getting up to 5-6 days with at least 24hrs screen on time but have seen 36hrs screen on before, minimum battery life i have gotten was a solid 48 hrs with heavy use and 26-32 hrs screen on.

I'm running stock ROM but removed bloat, CIQ, running leankernel and typically go 3 days between having to charge the phone.
I am on WiFi 90% of the time, and mainly just use the phone for checking SNS, email, and some texting/chatting and daily YouTube updates for 30-60 mins.
Been getting roughly 8 hours screen-on time before hitting that 15% battery remaining notification.

Yes this was stock at the time

I'm not familiar with the real-world performance of the G2 battery. But I must say that, by far, the Note3 has the best battery performance out of any smart phone I've ever owned. (Which isn't saying much cuz I can say that about every smart phone I owned compared to the previous phone) I just use it as much as I want. I don't even worry about it anymore.
I've even gotten crazy and started underclocking to 960mhz with conservative governor. Keep your screen around 40-50% and (so long as you aren't in a very low signal on all protocols area) it barely drains and I barely notice even the slightest hit to performance. (...and I am picky as hell about stuff like that. 30fps drives me crazy, I can detect latency in the 10-20ms range...it's a curse really). I just get a clump of lag every now and then. For 2 days off charge? I'll take it.
I don't keep track of screen on time...yet. I guess I should do that one of these days. But I take my phone off the charger at 6:30am and usually plug it in again around 12:30am or so...I'm usually around 35%, give or take 10% depending on if it was a heavy or light use day.
Sorry I can't answer your direct comparison question. I can't imagine a phone having better battery life stock (even if I didn't underclock)...but from what I've read in this thread the G2 is the one to beat. It seems as though they are at least comparable within a reasonable margin of error.

I've not had the G2 but from what I've been reading if they are fairly comparable with the GS with a 5.2" display and 3500mah battery and the Note 3 has a 5.7" display with a 3200mah battery I would have to look at the OS optimizations as being better maybe with the Note 3. Plus you do get the Spen and 3GB of RAM instead of 2GB of Ram with the G2

Note 3 Battery life is amazing and even better if you get the Zerolemon extended battery (completely overkill btw)
