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

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%.

Limit the Note 2 from 1.6Ghz to 1.1Ghz with build in feature to save battery

I know most of you already notice this but if you don't:
In Setting/ Power saving mode, check the "CPU power saving" then your phone will be limit to 1.1GHz max from 1.6Ghz.
I would suggest to tick on the "Screen power saving", "background color" and "turn off haptic feedback" to save some extra juice.

LTE on. 24h unplugged. 75% screen brightness. Full heavy haptic feedback. Heavy gaming and Internet use. Phone calls. Texting. 3D live wallpaper. Still 7h screen on time before the phone finally had to be plugged in.
I don't know what you use your phone for but I'm going crazy on mine and can't kill the battery. If you need more juice, then more power to ya. I can't fathom why.

LOL I tried to kill mine but it out lasted me I woke up at 5 for work and by end of the day I went on a 2 hour gaming session to try and completely drain it and got it to 9% but it was like 10 and had work next day so gave up. I lost

Try a day without charging your phone at your desk. Yesterday I pulled in about 7 hours of on-screen time. That's with LTE and anything else internet intensive you could imagine. The only way you'll overcome that worry you have is to test it out yourself. I'm sure you won't be disappointed.

I'm with you. I came from the Skyrocket and it was a struggle to get through a full weekday on LTE. In the past week with the Note 2 I don't even have to think about charging it when I'm awake during the day. It's very liberating!

I would understand this philosophy if the Note 2 didn't have an easily replaceable battery, but in a years time you could replace a poor battery for cheap. Just recently the stand with extra battery and charger was $30 on the Samsung site (it may still be that price)

I think its my ocd from my note 1. Always seeking the longest battery life possible

Damn, I wish I could get run times like that. I usually get HSPA signal and after 16 hrs I'm dead with 4-5 hrs of screen on time. I mostly text and do web browsing. Maybe an hour of music with wifi on all the time and auto brightness. Still lasts longer than my SGS3 did.

My first charge is 7 hours screen time for 24 hours unplugged. Now it's going down hill to 4-4:30 hours after i rooted and remove bloats. Installed couple MoDs.. Dammed i wish i can go back to 7 hours screen time

You do know to "remove bloat" all you had to do was go into the stock app manager in settings and disable anything you didn't want. That is actually a much better solution than "freezing" with TiBu or removing altogether. I'm not convinced root and mods are 100% stable yet. Most people reporting decreased battery life are those that have rooted or modded something. I'm still 100% stock with ATT stuff disabled and batt life is still 7+ hours.

Even bare stock I wasn't getting that much screen on time. So far I've only rooted and changed the kernel. Though today my battery life is starting off good. Yesterday I ticked the power saving option for the screen. I'll post an update tomorrow.

Today I was on for 5.5 hours, screen time of 2.2 and was at 54% with Power Saving On
So I went to bell and grabbed another battery
Time will tell if that helps
I could never reach 5 hours of screen time but could have the phone on for 30+ hours
I cant wait till we get more developer support, I used Francos Kernel with my galaxy nexus and it improved battery by 30 % and made my 8 hours overnight use only 2% battery. I was using 12-17% overnight with my note 2 asleep. Aside from kernels and roms I use this phone exactly the same as I did my Nexus. wifi off, bt off, gps on, push email on, auto brightness

Lithium Ion batteries actually do better if you don't charge it constantly. In other words let it run down a bit before charging. You don't want to always keep "topping it off". But in general these batteries are much more resilient than others.
Just do some research. There's lots of info out there.

Umm, no, it does not. You are stressing the battery out. Unless needed, dont keep the battery below 20%. Its healthier to charge the phone sporatically throughout the day.
These aren't nickel batteries...they dont need to be trained or "cycled"

I'm a battery test engineer so I have played around with Li-ion batts.
If you can keep the phone at cool temperature and charge at 40% and stop at 80% then keep doing 40-80, your battery will last double long

Agreed. Full discharges are not necessary for lithium ion batteries. Full discharges were needed for NiCad or NiMH batteries as they suffered from memory effect. LithIon doesn't suffer from this. With that said, a lot of experts do suggest discharging a LithIon periodically, maybe once a month or every other month.

ok so i watched another video about someone else saying he got 29 hours of power on a charge. im still getting about 8 with heavy usage. not rooted yet. is this normal battery life? screen is on 3/4 wifi is always off as is gps.

Wifi uses less power than 3g. 8hrs of screen on time is reasonable at stock imho.

With avg use, and counting that I do sleep 8hrs/day... I have 2 li-ion poly batteries & never tether to a wall... I generally get 24hrs, with about 10% or more remaining. I swap, read a book, until I am sleepy, go to sleep. The battery usually is about 95-97% when I wake up.

I don't think the op said that he/ahe is getting 8 hours of screen time. I think it's 8 hours total and if that's true then that's pretty bad battery life.

I have had the phone for a month now and have yet to kill it in under 24 hours (ok fine I got it to die in 23 hours and 36 minutes). I usually get about 1 day and 6 Hours. Of course, I am sleeping for a good portion of that... Typical screen use time is about 3 hours for me (inside that 24 hour phone use time) but I have done as much as 5 Hours of screen time. Im assuming that you could kill the phone faster if you really tried, but i have a hard time believing it would die in 8 hours unless you were doing everything you could to kill it..

ok thank you guys can i ask are you all roooted? im still on the fence about rooting this phone like i have my others. can not being rooted effect battery?

I'm rooted, running UltraLight1.5 with Perseus kernel. Rooting aside a big battery killer is the wireless network locater in Settings/Location Services. That stupid service kills battery with thousands of pointless kernel wakelocks. I used to disable Maps entirely, but that ain't needed.
I leave GPS &WIFI on all the time with screen brightness on auto, power saving turned on on the screen and cpu. 8hrs of screen on time easy...overnight at idle there's minimal eating of battery while I sleep.

my brother got 2 days and 8 hours. he uses wifi when at home. not sure about work. he has a live wallpaper. he is stock rooted.

Obviously heavy usage is relative. I definitely get over 24 hours worth normal use. I'm pretty much on it constantly. I would imagine if you are gaming or watching videos then your battery is going to die much quicker.

Being rooted doesn't give better battery life is just an access for to things you couldn't unlock before like admin rights.
However if you freeze a few apps you don't use and close any apps after your done with them you'll get better results.

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.

[Q] Getting terrible battery life on Moto 360

Hey guys,
I've had my Moto 360 since Sunday evening and have been getting to grips with the device for the past few days.. I have one big problem though :/ Before buying the watch I saw EVERY review there was to see and read EVERY article there was to read to have the widest opinion about it since I would have to order it without seeing it in person. I decided to pull the trigger and buy it... It was a bit smaller and taller than I initially thought, but I like Android Wear, don't mind the lag (even though I do notice it) but the battery has shocked me a bit tbh. Everyone said that a full 12 hour day with ambient mode off is no problem and after the update it should be even better. I don't get nearly at all this batterylife. I took it off the charger today at 7:15, haven't used it as much as I wanted to at all just to see if the batterylife is acceptable and now at 4:25 ( a bit over 7 hours later) I'm at 21%. I even formated the battery prior to this( drained it completely and charged it up completely 3 times) and will do again today. I reseted the watch AND my phone yesterday so I can't tell if it helped or not. I am running software version 4.4W.1 build number KGW42R. Any ideas ? I only installed pixtocam. :crying: What are your findings with the batterylife? Thnx
Edit: added build number
Oh and two last things: 1. Have been using with my Galaxy Nexus two days and since then with my Sony Z1 and 2. the watch takes longer to charge aswell I've noticed It takes cca 1 hour and 25 minutes to get to 100%
LAST EDIT: Down 14% in an hour and about 20 minutes.

I've been getting literally about 24 hours on one charge with the minimal watch face, and no ambient light (auto dimming on) there seems to be a correlation between watch faces and battery life. A basic face gives you more life compared to a face with many dials and info. This was only achieved after the last update. Before that I was getting about 13 hours.

I am getting awesome battery life out of my unit. It's currently been off the charger for 19 1/2 hours and I'm at 57%. I'm also on the same build/software version as you

I get close to 30hrs with ambient off and 15 with ambient on. I'm thinking you might want to exchange for a different one. Unless its pixtocam. Did you reset the device and install no apps for a few days?

I've only had it since Sunday so I'm going to try that today and see what I get :/ But replacing it would be a real pain I'm the a** since I'm studying abroad

Not pleased with 9 hour battery life
Ok, there is much variation here. I've had this for 3 days, charged to 100%...and after a 30 min commute, I'm at 75%.
I ride a motorcycle...is it possible the fitness sensor is going crazy? I had 3800 steps regsitered.
So today I turned the watch OFF and only turned it on after getting to work. It was charged to 100% before I left and it was 97% after 30 minutes...OFF! Today, after 9 hours I was down to 18% battery...I swiped maybe 10 cards, and checked the time maybe 20 times all day...no apps have been loaded other than default setup. It's build #KGW42R, ambient screen is OFF, watch face is MINIMAL.
I basically have to turn it off in the afternoon at work, otherwise it will go to 0%. I'm online now to find a charger I can keep at work.
Was expecting better...

Yeah man that sounds exactly like my situation! Apart from the fact I don't ride a bike lol Anyway I'm down 6% in an hour and a few minutes with basically zero use and about 10 time checks :/ it dies after about 8 and a half hours Thus being miles away from " all day battery life"
