Screen Time On Numbers

I'm starting to see that looking at battery life, we shouldn't be looking at any number but screen time on.
For me, no matter how long I use my phone. Let that be intense browsing to listening to music, my battery will not die until it reaches near the 2 hour screen on time.
I am trying to figure out if that is low compared to other users. If people can share that would be great.
thanks.

Hour and fourty five to two hours fifteen seem to be about the norm. Some users are getting ~3 hours of screen time with a lot of patience, kernel testing, fine tuning & tweaking as well as careful useage. I think we'll all get there sooner or later. In my opinion kernels can/will get MUCH better for this device. Only time can tell, but I'm not trying to put a show on. If I need my phone, I'm going to use it...whole point in having it.

Most GSM users get around 3 hours screen on time I believe.. I get three on a bad day

I have GSM with 2000mah extended and get average of five hours screen time and have Gmail accounts syncing Facebook weather and it lasts all day so I'm finally content with my phones battery life. Just don't need more

Actually both
1.standby
2.and actual phone usage
Standby can be sorted out via removing stupid apps or configs causing large amounts of wakelocks.
Actual screen on time AFAIK can only be done via lowering brightness, or maybe try reducing screen voltage(however, current may increase rendering this mute).
Having a lower dpi screen means less screen touch/input for scrolling so that also helps, it also looks great due to the high res screen (large ppi count).
obviously if you are doing battery intensive stuff like playing games or gps. Not much you can do there.

This is what I'm getting on average , GPS and bt is off everything else on. GSM 4.0.2

That's about my usage, I got two and a half hours yesterday. But I've since changed to Nitroz's Black Exodus so I hope to get more toward the 3-3.5 hour time.

I get between 2 and 2.5 hours with heavy usage on stock battery, GSM version, data on (2G screen off), sync on, AOKP M3 + franco kernel w/ turtle governor, 350/1000 UV. I'm trying gazelle with 700/1350 and I ordered the extended battery off eBay.
If you don't get at least 2 hours screen on with heavy usage (games, internet, etc.), research what is draining the battery.

On an average day I get over 4 hours screen time. A good day sees me hit 5 hours and a long time without charge can reduce this to around 3.5 hours.
I use the official extended GSM battery. Currently running AOKP 21 with Franco Kernel 14.4 undervolted by around -50mV. Auto-Brightness.
Here is an example of my last cycle.
Regards.

Stock everything GSM... Intermittent use of Skype. Wifi always on. Screen at 50%. Google calendar and mail sync.
4.0.1 just under 2 hours.
4.0.2 just over 2 hours and 2.5 hours max.
Average 16 hours without charge
I think it is just as important to post screen brightness as well as time on.
I've not yet tested a lower screen setting and I would be sacrificing its sexiness.

At least 4 hours screen time with:
Version: GSM GNex
ROM: AOKP Milestone 3 (power saver mode off)
Kernel: Lean Kernel
Battery: 2000 mAh
Frequency: 350/1350 InteractiveX
UV: -70 across all
3G/HSPA/LTE: 3G/HSPA and my network doesn't support 2G
What's off: BT, WiFi unless I'm home, Sync for Calender Contacts Browser and Photos.
Daily, I use: Netflix/Poweramp/Spotify/Reddit on my daily commute. Phone/Poweramp/Spotify/Reddit/Browser+ in between commute.
The WiFi is when I got home, and I didn't charge overnight, which explains the long straight line. My brightness is almost always at 40%, sometimes I go 100% if I get home and know I can waste the charge, sometimes it's at 0-10% if in very low light.

Amazing battery life on 4.0.4

I flashed Paul's 4.0.4 ROM a few days ago and my battery life has greatly improved. I wouldn't normally make a new thread about something like this but I've seen a lot of people complain about poor battery life. Hopefully this ROM helps others as much as it helped me. The ROM is still in beta but it's surprisingly stable.
I always keep my brightness at 40%

Maybe so, but neither stock nor 4.0.3 with Franco's kernel has been able to achieve amazingly long idle time and still handle hours of screen time.

Yeah, that's pretty low for a day and a half worth of usage. We already know that the Galaxy Nexus idles like a champ.

He still has 60% left so he's still got a lot of usage out of that charge. Could be looking at 2 days at that rate but yeah you don't really use the phone that much do you.

I've seen as low as 0-1% battery lost over 8 hours of sleeping before. So that plus WiFi for a full day isn't hard. I've been at 75% battery before with a full 24+ hours used but it was on Wifi with little screen usage and minimal things like texting and short calls and not much else.

I've managed 2 hours 40 minutes screen on time over 42 hours with eight percent left leaving brightness on auto, using AOKP and Franco 16.2.
I think that's pretty decent.

I second this, another thing is half the time people forget to mention their on AT&T not on Verizon, and they compare their 2 day battery life on GSM to an LTE phone...
My biggest battery hog is exchange syncing every 15 minutes, and with that and LTE with nothing but stock apps in the background I can get 2, 2 1/2 hours of on screen time within a day

[Q] How to get the most of out Gnex Battery

So I've tried various things, disabled apps I don't use such as Email, Exchange Services, News and Weather, and even disabled the Gallery app and using QuickPic instead (on GB, Gallery was known to waste battery for no reason). Also turned off data and connected via 2G only to save battery, have brightness the lowest possible, turned off auto sync, and yet, still don't have near as good battery life as on my GB running LG G2x.
So my question is, what do you guys do to get as much battery life as possible?
Sent from my Galaxy Nexus running AOKP+Franco

airplane mode...
jk. what kind of battery life are you getting? Maybe run stock?

Ha it seems to not have to do with the wireless settings at all, drains either way.
And with GB on LG G2x, got 12 hours of constant, heavy use. Music, XDA, Pulse, FB, some gaming, texting all day, definitely used my phone.
Now, with AOKP+Franco, getting around 8 hours of light usage, just messaging and music. Wi-fi on for not even an hour, and didn't play with it much.
And maybe I'll give that a try, I just love all the options in AOKP.

I'm in the same boat. My friends are on stock and claim they get much better battery life. I'm on AOKP with Franco and seem to be the same but I might give it a try... but love the little tweaks of AOKP that I probably won't

Might try Apex, battery lasted nicely if I remember correctly the few hours I ran stock. Apex is basically stock, with tweaks and customization.
I know for most phones, AOSP and similar based roms almost never provide as much battery life as the stock software w/wo tweaks. There are some exceptions, but maybe ICS is different. Going to flash Apex and tell you how it goes tomorrow.

I was actually just reading a thread someone posted about this. This guy has some pretty good instructions, I would read this:
http://forum.xda-developers.com/showthread.php?t=1226016

try the "on deman" governor , it worked very well for me...

Yeah there's nothing you can really do man. SAMOLED just takes up so much more battery than our old G2X's IPS. That's pretty much the only difference. Probably nothing web can do. I bought 3 spare 1750mAH batteries plus an external charger all for 13 bucks to compensate. That's the only way for me to fix my battery issues.

Oled uses more energy than LCD. You fell for the marketing. They are relying too heavily that black doesn't use energy but who uses all black screen?

That's true, I keep try to keep everything dark, gonna have to invest in a extended battery I guess.
Sent from my Galaxy Nexus running Apex

It is what it is. It could improve in the future, but oled has more visual advantages than LCD. I wouldn't get my panties in a was over it though. And just to throw it out there, bigger pled screens use more energy than a comparable LCD because of the pixels that are lit. The LCD screen is more constant because of back light.
...of the people, by the people, for the people...

Thanks for that, will definitely keep that mind when buying a new phone down the road. Hopefully not too soon.
Sent from my Galaxy Nexus running Apex

It appears that at lower brightness values, it's not the screen that's causing power drain. Though indeed, current S-LCDs are about 3 times more efficient than OLEDs when displaying white at same brightness.

not bad for me

Poor 3G signal will ruin the battery. As well as using that stupid Facebook app. Uninstall it and use the web browser. Also how much screen on time.
Sent from my Galaxy Nexus

Right now it's at 54 mins.

absolutely, that damned facebook app! your screen on time is adout an hour there(it looks like). is your brightness up high or are you using auto brightnes? do you have root, what governor are you using? whats your cpu speed?

Yeah about an hour...... It was at half brightness...... Rooted....... Franco kernel milestone 6........dyninteractive governor....... 230 mhz Min. 1036 mhz max.

try ondemand/deadline sampling rate 15000 up threshold of 98%, or try interactive/sio(i dont use it so cant give you good settings for this combo). if still fine for you, lower the brightness a little more(33%?).

there are a few good posts out on the net about how to save battery life. common talking points would be
Turning off Wi-Fi
Adjust screen brightness
Turn off mobile data when not needed
Turn off Sync for apps that don't need to be always in Sync
Haptic feedback
and many more..
I guess these are the really common ones, so give it a try and see how it works for you

Actually I get way better battery life with wifi on its weird.....if I use mobile data my phone gets hot and my battery just falls!

If you have a VZW Nexus I don't think it's an app, the screen, etc. The wife, the girlfriend, and I all have the Nexus and none of us can make it through the day for the last week or so. The drain is terrible. And we don't all have the same apps installed. I wanna say something's changed about LTE because besides the hardware and Jelly Bean it's the only thing absolutely all three phones have in common. But I have no actual proof, so...

I have the sprint galaxy nexus, and honestly your battery life seems pretty normal if its a CDMA variant. I'd actually consider that to be pretty good battery life considering its a CDMA nexus

Was that with the screen on the entire time? Or mostly idle and screen off? For screen on, that's not that bad. For idle, that's a little off. Me, personally, I only get about 3 hours at below minimum brightness (modified with rom). Try turning down your brightness even more. It should help. The screen is the biggest killer of battery life on the nexus, especially because it's not optimized for it. As well, keep wifi on. Don't turn it off. It'll just waste more battery switching it constantly. Only turn it off if you are going to be using data for an extended period of time. As well, you could try a different kernel. I'd recommend trinity, but it depends on your rom and what features you like.

An hour screen-on, 50% brightness, and the Facebook app can easily chew 33% of your battery... especially if you're on a stock battery.
As an aside, how can you even stand 50% brightness (assuming you're not in bright sunlight)? 50% just seems way too bright. I typically run at 10% brightness indoors, even at work, where we have fairly bright fluorescent lighting.

True that! At first I didn't think the FB app was consuming that much battery, but I tried uninstalling it and the battery statistics have greatly improved. Hope FB gets to fix this soon, it's nice to use facebook through a native app rather than a browser. Don't you think?

Try Fast For Facebook, it doesn't offer as much as the regular app, but it's an app and it doesn't suck up as much juice.

Damaged battery?

Hi guys, I'm a happy Nexus 5X owner, except for one thing: battery autonomy.
I had a true hope that Nougat would change my perception, but I got no improvement at all. After that I tried ElementalX kernel running every profile, including the newest GlassFish 1.2 and HawkTail 1.2. I also use Greenify and don't have facebook app installed.
I unplug my phone everyday at 7:30 AM and it can't get past 2:00 PM. My use is *only* web browsing (chrome) and whatsapp. Nothing like youtube, netflix, gaming or listening to music. I get only 2h30 SOT.
I've been using this charger for about 4 months: http://www.gearbest.com/chargers-cables/pp_350509.html
My question is: could my battery have been damaged?
Thanks!

Probably just the usual combination of Usage, Settings and Signal. We could only guess without some screenshots though, there's a battery life thread in General where you can post them and get advice.
The one thing I can suggest to evryeveryoneone is to use Developer Options > Running services and see which of your 3rd party apps are running 24/7 in the background. These are using your phones resources even if you never launch the app.
Nothing special is needed to get good battery life on this device, I typically see 5-6 hours SoT over 24-48 hours with stock 7.0. No root or loss of features.

I'm afraid of overheating because I sleep with the phone charging beside my bed.

Honestly, whats your brightness? Do you use bluetooth? Is NFC turned on? Location? Are you running 2G/3G or LTE? WIFI? Do you have wakelocks? I can make my nexus have 3 hours SoT ober a day also. But I can also make it have 5. Its all usage dude, unless you see a lot of heat, or drops of 5% over 5 mins, id say you battery is fine. Maybe its just the charger that doesnt fill it right? Why do you use that charger?

Thats actually normal considering you have auto brightness and half the time on 3g. However, your whatsapp usage is huge. Try running withouth it for a day. And do you really need location? How is your signal strength?

Hell yea. If you have it on 50% and use your phone anywhere outside or somwhere where the phone determines that you cant see it clearly, it will crank up the brightness, and that consumes a lot of battery. Try running it on 10-15% manual mode inside, and 20-25% outside or more if you really cant see, but keep the brightness mostly to 25%. The screen consumes a lot and plus 3g, no wonder you have such bad battery life :/ On 10% brightness, you can pull off 4 hours for sure. At least I can
