Develop Bugs

Now this battery life is more like it

-Wifi and Bluetooth on whole time
- Tons of texting, a lot
- Over 1 hour of phone calls on Bluetooth
- Over 3 hours of A2DP streaming
- Periods of no signal (subway)
- Screen on for 2 hours
- Google Reader and Web browsing
- Used the phone as I would normally without thinking about battery at all.
Very very happy. UPDATED with recent screenshots before I plugged it in.

Out of interest, how many times have you charged your phone (0%-100%)?

Never drained it to zero and started using it right away without charging it. Its been charged to 100 twice already. My uptime is 73 hours and that's exactly how long I've had the phone.

Wow! I wish mine was as good as that, seems to be getting better with each charge though, which is a positive.

Most I have got is 12,
Hopefully this will increase over time

Probably dim screen. Usually screen takes 60%-70% of the power.

Honest question, how many times are you more than 12 hours from sleeping or relaxing in your house?
12 hours is more than adequate for a normal user

This is mine after a fresh wipe and no apps installed. Just thought i`d see how it did with normal use.

Here's mine; at a point the phone got itself shut down for some reason, and I couldnt get it restarted at that moment, so I left it like that, and when I could turn it back on, it was quite warm around the camera unit, and also the battery was pretty much drained - thats what you can also see on the screenshot at the "20minutes" part of t he scale. After I've removed the battery and put it back, the phone was working for quite a while again, like 12 more hours.

I'm sure auto brightness helps as it keeps screen dim but during my use it was brighter especially outdoors. My whole point is there is no secret, you should use the phone as you would like it. One thing I could have done I'm sure to improve battery life is turn off wifi and bt when they weren't in use and possibly not have as many apps running but then what's the point in having the phone?: D

I get around 11-13 hours. Not too impressed. My iPhone 4S gets 20 easily. I'm really conservative on my Nexus too because doing anything intensive (games, video recording, youtube etc) really rapes the battery. I'm guessing some of you turn off auto sync or something.

I'm currently on 1 day 1 hour, with 50% left. Although with light usage.

It's simple really - the more you use the phone the worse battery life is but that's because you used the phone more! I never use the phone LESS just for battery life because then you're doing yourself and the phone injustice.

43% - 14h.. screen taking up 48%

from what I can see, apart from the screen, the biggest battery hog is wifi/3g
I installed Juice Defender and I am getting fantastic battery life now:

So JuiceDefender works fine for you? I just read that alot of users had problems with ICS and JD. Would be great if it worked though!

Here's mine. Since I was at work all day I only got time to play Dillo Hills for about 20 mins but I've found the battery is REALLY good after flashing the Android Revolution ROM. MoDaCo causes too much drain IMHO.

Battery life isn't too bad on mine. I got mine on the 10th and I used it right out of the box. Battery life wasn't that great until I did a charge to 100%. The OTA update didn't change much for me in regards to battery. Currently at 21h uptime and I'm at 32%.

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.

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).

[HOW TO] So I'm getting awesome battery life...

13 hours and only down to 60%. My calculations that's possibly up to 30 hours over a whole charge!
No extended battery, normal college student use. The big kicker is having wifi connected when possible, but even so I was also listening to spotify for awhile and texting. Currents was up there as well.
Here's what I have:
CM9 kang (1/5/2012)
Jdkernel 1.1.2
Use no-frills CPU to set governor to smartassv2 (no locking up on wake, always loved this governor)
That's it! Hope this works for you guys.

Also I noticed wifi was on for majority of the time. I always get better battery life on standby when wifi is connected but I don't have access to wifi when at work.

It could still be better. The Android OS should not be that high on the list, it is consuming CPU time and awake time.

My battery life has improved significantly in the past week. I now average 16-22 hours between charges.
I'm using the extended battery, and I've been "conditioning" it by letting the battery run to 4% before charging it completely to 100%. My phone sees mild to heavy use (mostly podcasts with the screen off), always on LTE, never wifi.

I wouldn't run it down that far often. I personally try not to let mine run down past 20%. It hurts your charging cycles. Some people recommend higher. It is true though keeping charged and not at 95%+ helps longevity of battery.

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.

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.

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.

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.

Hey guys, how's my battery life?

im posting a day's usage for GS3 Tmo
can you guys tell me if the battery life is normal, bad, good?
(im posting the batt. life and top 5 usages)

completely stock, tmo bloat disabled, screen @ lowest brightness, sync off

With 27% left, I'd say that's about average-good.

Dear God, I get about 8 hours with average usage. Seems very good life to me. Do you have power saver and/or sync enabled?

It's exactly like mine. However, some users actually got theirs up to 5 hours screen time. How? I'll never know

Battery life good bro, cool story

Mine's absolutely horrid, I can't for the life of me figure out what the hell's wrong with it. I'll run out of battery after about 12 hours, with the screen time at 1 hour and maybe 30 minutes if I'm lucky? The phone drinks away my battery in standby mode like a former alcoholic united with an opened beer. When I was on ICS, turning off 4G every time the screen was off with the AutomateIt app would give me excellent battery life. Ever since Jelly Bean, it doesn't seem to make a difference. I just don't even bother using AutomateIt anymore, I even uninstalled it. Useless. I check marked the option, "Restrict Background Data," but I actually had worse results with that on even. Following the thread about the Guide to good battery life, I turned off auto-sync. The only thing that seems to do for me is not get my emails in real time. No effect on the battery though. I'm guessing the battery drain has something to do with being on data (even though turning it off doesn't seem to do much) because everytime I go to school where there's little WiFi, battery's worse. Also, somehow my Messaging app takes up more battery than the screen. What's with that? I'll text every now and then, but it shouldn't eat away my battery like a fat man with the last batch of Twinkies. Enough with the dumb similes, haha, but I actually need help with this. I really don't wanna buy a battery off eBay cause the damn people are too lazy to send you the battery until a month passes, and I hate charging in the middle of the day.
I'm on 100% stock. I used to root and mess around with a ton of ROMs, but then I realized all my favourite ROMs were the ones closest to stock...

.... look at the eBay expected arrival and/or look for a seller in the USA ?
Anyway, that bit aside - have you installed something like BetterBatteryStats to be able to see what the problem is so you can fix it ?

5 hours... how !?
Easy !
I'm on stock and if I'm almost all the day on WIFI, not playing too much games, and with auto-brightness,
I can get 5 to 6 hours screen time.
(but on 4G all the day, it's more around 3 hours screen time)

This is what most people get with normal use around 14 to 16 hours and 4 to 5 hours screen time. I think the biggest issue is that 4G radio that most people have on all the time. I I have wifi everywhere so most of the time I have mine off that helps a ton. Plus all the sync stuff off, I get about 6 hours over 17 hours battery life and about 30 to 40% brightness.

14-16 is what was normal for me when I first got my GS3 (after JB update). If you want more battery life, I recommend trying juice defender (custom settings for data off while locked). If you have stretches where you don't use your phone it works really well. Just thought I would throw that out there.
