Anyone ever see how long the display stays on?

Before the battery dies I feel like it drains alot of battery was wondering whats the most it can stay on for.Im starting to think 2 hours.

It's much more than 2 hours...I remember reading in a few threads people have gotten 7-8 hours of display time. If your phone is dying in 2 hours of display time there is something seriously wrong with it. 2 hours probably brings me to 75%

7-8 hours with the screen on the entire time I dunno thats crazy I wish it lasted that long im gonna test it soon as i get a full charge

Yeah, my impression is that 4-5 hours of actual screen use time is average. It's the standby times that really matter, in terms of variation in batt life.

I agree 4-5 hours on auto brightness is probably the average, depending on what you're doing, obviously. I've hit 10+ hours with the screen on while using the Kindle app with white on black and minimum brightness.

I usually get around 2 hours max at 25% brightness...

You guys must be doing something wrong - like something wrong with your clock. I can play Angry Birds for more than 2hrs. Obviously, that's screen on, plus significant CPU/GPU usage.

If you're only getting 2 hrs, there's something wrong with your phone.
I needed to drain my battery completely last week so I cranked the brightness all the way, turned on GPS and 3G, set it to never sleep and set Angry Birds running and it took well over 2 hours to drain completely, and that was from 80% charged.

I got 3 hours with farm story open entire time I let the phone sit 10 percent left lowest brightness I did everything else to save battery but when it comes to display I'm at a lose any ideas

Just for some reference,
I have 50% battery now,
72% Is display and its time on 1h42m
Sounds normal isn't it?
Though I don't really like it

I was looking at system panel farm story was using 100% cpu the time it was on maybe I'll try with angery birds and see what happens 3 hours tho is bad id be happy with 5 at least

So does anyone have any idea how to prolong the amount of battery used while the display is on? I think someone suggested clearing the battery cache but I'm not sure how to do that...

"Reconditioning" your battery will not make it last longer. At all. It will EVENTUALLY (after several complete charge cycles) make your reading of the battery level more accurate across the whole discharge cycle. Wiping battery stats is, for the most part, a placebo. The only time you should wipe your battery stats is if you flash to a drastically different ROM/kernel or if you get a new battery.
If you want to get less drain from the screen itself your only options are:
1) low brightness
2) avoid the color white. A black pixel on a SAMOLED is literally off, a white pixel consumes the most power possible and it's a sliding scale in between.

I was browsing for about 2 hours and battery dropped to 70%. Brightness is adjusted 25% or less though.

Nexus 10 battery life

Hey everyone. I ordered my Nexus 10 in late March and just had a question: How much actual battery life do you get out of your N10? I found that I was barely able to get a day out of mine and am awaiting a RMA replacement. I did a Netflix test, where I charged it to 100%, unplugged and played Futurama on Netflix. I got about 5 hours 12 minutes before the device shut off. I have my screen brightness at 50% and no apps that would cause heavy background usage.

That is pretty good battery life for 50% screen brightness. I still cant comprehend why people need their brightness at 50% or even higher though.

Some people like me use their tablet in brightly lit rooms and outside which means in order to see the screen you need to have the brightness cranked. I never use my tablet in dim rooms.

7 hours man. That is too much

What do you have your brightness set to?

I'm on on the 2nd charge cycle, but I got almost 5hrs screen time on last charge with about 30% battery left before putting it on the charger. Pretty good in my opinion.

Mostly web surfing, youtube, gmail, G+ and facebook. Not too intensive, I suppose.
I have all sync on except for facebook and display on auto brightness. I also have a strong wifi signal most of the time.

When my tablet is AT HOME WITH ME instead of off cavorting around Samsung repair centers, its day starts about 6:45am. With all my apps and syncing, it lasts me through a work day and then some, going as late as 11:00pm and still being at 30% battery or more, depending on how much gaming I did.

When I am inside it is at minimum (which is still too bright), outside is between 25-35%
For the people who have really low battery, I have a good hunch that the problem is how much wifi sucks up. When I have wifi on I can feel the tablet is much hotter than normal, which means it is dissipating a lot of power. I suspect that the wifi traffic is the 2nd biggest battery drain for people who are browsing all day, the 1st most being the screen itself.

11 hers for me.... No gaming for that amount but still. How much more do you want
Sent from my Nexus 4 using xda premium

It seems there is a common trend with people who have long battery lives - low brightness. My eyesight is pretty bad so I really can't stand setting it any lower than 40%.

I get about 7 hours before it needs a charge and that's mostly browsing with wifi, which sounds around right according to claimed stats by Google. I'm on around 20% brightness, doesn't need to be higher.

About 8 hours, which is a full workday for me, mostly Evernote/webbrowsing/mails - no gaming. I usuall have ~20% left, so there's 1-2 hours more for emergencies.

I just ran both my original and RMA units side by side, factory reset and unrooted on Youtube playing a 10 hour loop video with brightness set to 100% and at 5h 6 minutes my original N10 hit the 15% warning, the RMA a few minutes later....so I feel kind of bad for wasting Googles time.

I think kernel and ROM have something to do with battery as well as WiFi. I have great signal and use 5ghz and I get great battery life with little drain. Before ras came to the n10 I was using cm and got amazing battery on the kernel it came with but horrible life on paranoid (early build). Also the first trinity kernels had poor battery life for me.

Is my Nexus 10 faulty?

I've had it for around a week now but I've yet to get over 6hrs battery life. I keep the display on the dimmest setting, have no bluetooth or anything on apart from wifi. I keep location services and Google Now off and I use it mainly for Internet browsing, you tube and a couple of bejewelled type games for around 10 mins a day. I haven't watched any films on it or played any real heavy duty cpu smashing games at all.
No matter what I do, I just don't get any more than 6hrs before I get the 15% battery warning.
I don't appear to have any wake locks, the battery graph shows that when the display is off, the tablet never seems to be awake.
I installed Better Battery Stats but I don't really understand what to look for.
Can anyone suggest anything before I give Google a call and they tell me factory reset and try again?
Any help would be greatly appreciated!

Mind posting a picture of your betterbattery with:
-Partial wake locks since boot
-Other since boot
If you use it like you explained you should be getting more than 6 hours.
I'm using a custom rom and kernel so that might explain why I can idle for an entire day and only lose around 6-8% depending on how many emails I get.
Typically I get around 8 hours of use which includes watching movies over stream, YouTube, flip board, email, xda surfing, and a few other things.

Charge your device to 100% and use your device the way you typically have been. Once you get down to red numbers, post a screen shot of the regular Android system battery usage. That might give a better picture of what's going on.
You can also charge to 100% and disconnect from the charger and let your device idle. Better battery stats is a better tool to use when you aren't using your tablet, and you are experiencing battery drain.
Also, you didn't mention whether you are stock, rooted, or rooted and ROM'ed. Please do that and we can go from there.

You said 6 hours battery life in OP, implying you were getting that battery life for the device... ._.
Congrats. You have a normal device... People may be using screen filter to get those results, but why not just enjoy the screen instead of gimping it for an extra hour or two of dimly viewed screen...It's not too tough to charge it overnight.

And if its really that big an issue, go get KTManta, Franco, or any kernel that lets you reduce the maximum clock from 1.7 to 1.3 or 1.2 GHz. I have benchmarks for the Manta at frequencies ranging from 1.2 to 2.1GHz and there's not a big difference in performance.

Battery Life Worry/Question

My battery life has been pretty good. However, the number one thing consistently using battery is "Android System". Is this normal? Thanks!

Same here. On all my other Android phones Screen is the top user.

U are using ips technology on the screen unlike amold that saamy used which kills the battery in hours in full brightness . As you could see that the iPhone has good batttery life because the 720p ips screen.
Sent from my LG-D801 using XDA Premium 4 mobile app

I've found that rebooting the phone after taking it off of charge, the battery life is awesome. There seem to be some wakelocks that kill the battery and for some reason, charging has something to do with it.

I don't know if this is why, but I heard the G2 has special screen technology that greatly reduces battery drain.

Those claiming that Android System > Screen for battery use on the G2...I'm coming from a Nexus 4 which is also IPS.

Yeah, somthing about 30% lower battery use or something like that. It's 6 hours since I took mine off the charger, must admit very moderate use, some toying, some photos, some mails and 1 phone call. but still, my phone is at 96% battery. My old S2 would be at 60% at this point.

I tried this and it worked. However, one instance is not proof I guess haha. I will experiment more tomorrow (namely, not rebooting after charging) and let you know what I find. I wonder what specifically about charging may cause wakelocks?

Over 48 hours of use, more than 50% battery left. 3,5 hours screen time. Android system worst offender with 35%, screen 2nd with 25%.

If you look at the programs listed under Android System, try uninstalling the ones that you would never use. This has seemed to help me. But to be honest it was kind of unnessary because the battery life is just crazy badass. In a few weeks or so when the devs have there way this phone is going to be epic.

It is two things, which by the way are great news.
A) LG's screen tech which doesn't refresh pixels when the images are static
and B) IPS
What we can't control is screen power consumption, but guess what? We can control android system consumption through kernels and roms. This means that we can *hopefully* expect EVEN BETTER! battery life since the screen is, for 80% of users, the main culprit for energy drain.

Just a quick note that flashing CleanROM on my ATT LG G2 basically took my battery life from <20% at the end of the workday to just under 80% at the end of the work day with increased use on the CleanROM install. Highly recommended.

Been off the charger since 6:50 this morning. Sitting here at work doing some texting, Words With Friends, and a test call for a co-worker...96% at 12:15pm. My Nexus would have been at 40% by now.

So is Android System different from Android OS?
I normally can squeeze out 15-22 hours since installing Snapdragon Battery Guru. Which has been working great until today.
Here's my situation today:
-100% charge at around 1230am. Light to moderate usage leaves me with
-77% between night before and waking up (only dropped like 2% overnight) at
-830, then i worked from 9 to 1230 so i didnt use my phone too much. But since ive been off work ive been using it more so im not too surprised about my low battery level currently.
But what concerns me is Android OS using half my battery! It says its been active for more than 4 hours and i dont understand where it comes from. Its way more than my screen usage even with a screen time of little over 3 hours.
Anyone know whats up with Android OS? It doesnt tell me what is running when i select it so im lost.
Also ive done many of the suggestions in this thread with positive results. Ive been monitoring my wakelocks and since doing some of the suggestions on here nlpcollector has actually gone down.

Just to benchmark .... I used the phone moderatley ..
I did.. a little over 50 hours of total on time
4.75 hours of on screen time,
2 hours of spotify with bluetooth for the entire time,
2 hours of MapMyRun with GPS running ..
then various text messaging and a couple phone calls
The only modifications i've made to the stop experiance is taking of google's location service for programs, but leaving GPS active .. and changing the screen to auto-brightness, baseline of 50%.
I came from the SGS2 ..... with 1 hour of on screen time and the other spotify and bluetooth .. i'd be around 10-20% after 8-10 hours !!!!!

Mines pretty awesome.

I'm not sure if my battery is defective or not. Right out of the box was around 75% and I drained it until it turned off then charged it to full.
Over the next few days at work it's on wifi and then on 3G/4G before /after work. I pull it from the charger at 7:30am and by 7pm its at 40%. Then on Friday night I unplugged it at 12am with 100% and woke up the next day with 80%. It's dropping like 1% about 10-15minutes. Would a factory reset fix the battery drain? or call for a replacement?

Battery life struggles

Is anyone else struggling to get more than 3hrs screen on time in a 12 hour day. I don't game or watch a lot of videos. It seems like the phone isn't going to sleep when I'm not using it. Just testing the waters if my unit is defective. I mostly web browse and read stuff on g+. My screen brightness is a little less than half with adaptive brightness on and enhanced voice over lte is disabled on Verizon. Thanks for the help.

3 hours of screen on time seems pretty good for a phone with a screen this big and with brightness around half way up. Is 3 hours SOT bringing you down to like 0 battery?
What do your battery stats say that make you think your phone isn't sleeping?
I only really tested the battery and checked the stats twice and I think the second time I had 2.5 hours of SOT over the course of 13 hours and my battery was at about 38% (also on Verizon).
I think that is pretty reasonable. If I could get 4 hours of SOT from full battery until dead I would be fine with it. Others have been posting much longer battery lives though.
I have read on this forum that one person tested the phone with the screen looping a video at full brightness and it lasted over 5 hours. http://forum.xda-developers.com/showpost.php?p=63642067&postcount=391
Some people are showing screen shots of over 5 hours of SOT http://forum.xda-developers.com/showpost.php?p=63690175&postcount=462

Off charge 23 hrs ,been using mix if WiFi and 4G all day and some poor signal areas

Do you have your bluetooth always on?

No never on unless I need it ,have WiFi on all the time and toggle mobile data on and off as I need it

Yeah my mobile network signal is mostly orange and red. I keep Bluetooth on all day for my smart watch

I found my moto 360 was keeping my phone awake (possible bug?). so I disconnected my watch and the phone actually slept when the screen was off! Give it a try!

I just have a pebble but I'll give it a try.

At 2 hours in 13 mins screen on time. Phone seems to be sleeping now but there is a bug in my battery stats. Any clue?

Here are the screen shots

Still not impressed. The phone isn't staying awake now that I disabled Bluetooth but isn't going to doze. I have purposely tried not to use my phone today.

Battery is terrible. I'm hoping once some new kernals hit it gets better... Because right now I'm thinking of returning this thing.

I am not sure why people keep complaining about BT on. I leave mine on all the time. Although i don't use my smart watch any more, so it is only connected in my car and my BT speakers at home when I want to listen to music in bedroom or so. I don't have any drains. I get 4-5 hours SOT in 24 hours. This is a first for me always owning nexus in the past. I am very happy. I also started testing the force doze mode on screen off setting with greenify today. It is making standby noticeably even better.

First day with pretty heavy use. The best battery I've had in a phone.
