My - Battery Sucks -

I have to charge it twice a day, and my use is for only couple of hours talking and few browsing.
I tried that with stock as well as
[ROM] cwm-Phantom-X-
is anyone else also experiencing the same?

a few hours being like 10 hours straight talking?

You're crazy. This battery is the best I've seen in a long time.

im getting 12 hours with normal use and 8-9hours with very very heavy use(basically on my phone all day non stop)

I can drain a battery in 6 hours or less. I can't make it through a 8 hour work day without charging it. I guess you guys that go 12+ hours on a charge aren't power users. I tried every rom and kernel and my results are exactly the same.

Maybe the people who are complaining about battery life came from a flip phone or a blackberry. As far as smartphones go, this is the best you'll find for the features and enormous screen we have. Don't believe me then get an Amaze, Sensation, myTouch 4g Slide or G2x.

this is exactly what I am talking about.
Before I had HTC G2 and same amount of use it last for whole day (around 12+ hours) but this one hardly goes upto 7-8 hours with one charge...
I did the battery wipe with full charge, if that makes any difference.

I dont know bout anyone else... but the only battery problems ive experienced is the fact that ive become so damn lazy on keeping the phone charged.
The battery lasts so long that i forget to charge it, and then i run out of battery

I'm a heavy user literally all I do is watch 1080p movies and plays games on my phone. I get twelve to fourteen hours every day. I also get at least a text every fifteen minutes if not more. Maybe the developers didn't remove career ciq which bogs down performance and drain the battery. You can also try a different kernel.

don't forget that in areas where you have crappy signal, you phone pumps up the power to try and compensate. you may notice your phone heating up in your pocket too. If you have no signal at all, i weep for your battery life.
go into airplane mode to save juice.

I too get 24 hours or more from light to moderate use with juggernaut.
Heavy use still nets me at least 10 hours. Although I toggle things off if I remember and don't need them. Like wifi, data, auto bright, sync, etc. although WAY lead important with this phone than it was with vibrant running cm7.

I had some weird battery drain with the stock rom. I couldnt get more than 5 hrs with light usage or heavy usage. I flashed streamlined (a mostly stock rom) from teshxx and im back to having 9-10hrs of battery life with moderate to heavy usage (3hrs of on screen time)

Why don't you try adding another core to your G2 and see if you can even get 6+ hours!!!
Cmon man, this is a dual core phone...it's just common sense that it will use twice as much battery power to get it to run smoothly.
But honestly, I was able to get 21hrs out of a full charge. With heavy use but i had it UC'd @ 1.2max and 192min. Still ran pretty smooth tho.

I get about 18 to 20 hours from a full charge. Stock. Non-rooted, and no modifications of any kind. I have all my apps auto-sync every 4 hours, and my usual display "on time" is around 4 to 5 hours. Here are some screen shots. This is the best battery life I ever had.

Just to add. My brightness is at 40%

is it better to use autobrightness on our device or a set brightness setting to save battery?

I'd say set it to certain level. Having the phone constantly adjust I would think would use more battery.

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.

I would be ecstatic with this performance. I would say though that I am lucky to get half of that screen time, with brightness set at about 15%.

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).

Battery life Note 2 compared with S3

Aloha
I currently have the Galaxy S3 which is one of the best devices I have ever owned. Unfortunately the battery is quite disappointing. I only get 7 hours of battery life on heavy use (Wifi off, screen off, GPS off and only 3G) and I am thinking about switching to the Note 2 which has a superior battery.
My question is: is the Note II's battery life vastly superior to that of the S3 or isn't it that big? How long does your phone last on heavy usage?
Thanks

I regularly get 5 hours screen on time. I have no issues making it through a 15 hour day on a charge. The Note2 has a 3100mah battery, even with the bigger screen it will do better then an S3. I only owned an S3 for 20 days and returned, so I really don't have a clear idea of what battery life was like. At the time I liked my Note1 better and returned the S3.

All right thanks. Does the Note 2 get hot often?

i Have them both and the N 2 isway better i get easily 7 hours screen . The phone never gets hot. Its vety fluid. I hate using my s3 now lol. I might sell it for a grey note 2
Swyped from another galaxy

I have an S3, used if for about 4 months (wife has it now), and I can easily say the N2 has MUCH better battery life. I got maybe 7-8 hours out of my S3 (moderate use during the day) before I had to charge, the N2 I can get about 12-14 hours, same amount of use. The S3 is a great phone, but the N2 is much nicer as far as battery life, and is just so much more 'snappy' to use.

Much better battery than s3. Mine gets warm at the top around the camera area if I play need for speed most wanted for about half an hour or more straight. But not as hot as my hox got

on the other hand .. I can use my note2 until 9pm when it hits 20%.
if without the use of chat app. it will last even longer.

Sent from my GT-N7105

My Note 2 battery lasts 30~35 hours with moderate use. That includes gps off, wifi on always, 3g off, 20~30 minutes of voice calls, 4~5 hours screen on, everything in sync (dropbox, skydirve, camera uploads to both dropbox and google drive, gmail, etc), browsing, tweeter, and some games. My experience with Note 2 is much better than Note 1 and the good thing is it does not get hot like Note 1 or One X (could reach upto 47 C even with few minutes of game playing). Very moderate temperature (max 35 C) even after playing 3d games for some time.

Using galaxy n7100 i have 10:00 hrs screen on, and using gsIII i had 06:30 hts screen on.

It depends on your usage. I get about 3-3.5 hours of screen time, because I use my phone for instant messaging and downloading and uploading, that's all. I mean, I use the calendar, and other apps. But 99% of my battery usage is screen + data. I go to bed with about 1.5 - 2 hours of screen time with 30-50% battery life. A lot of wifi, but at work no 3G (hardly 2G!) and very low wifi signal. So I imagine a lot of the drain is from the strain of trying to hold onto data connections while I continually send messages / pictures / download / upload / etc.
But for sure it has a VERY good battery. I had the note 1, my partner has a S3 and the Note 2 has great battery life compared. Once again, it depends on your usage.

[Q] Battery Life

I'm a bit confused here and hope someone can clear it up for me. Some of the reviews are saying the battery life is under eight hours. However the review from Androidpolice is saying he got 22hrs heavy use and with normal use it could be almost 2 days. Can someone tell me what the battery life is really like?

I suspect the shorter times are referring to performance in a battery run down test where a HD video is put on a loop and played until the device dies.

I have only had mine for 2 days and this is not normal use because of downloads etc... but I believe I'm getting 8-10 hours out of the 2014 edition where I was getting 6-8 hours out of last years Note 10.1. I still have last years model as it is going to ebay soon so I know there is an improvement!

I'm hoping it lasts 9-10 hours at least. Coming from an iPad, I have a feeling the battery life will be one of the worst things about android for me.

I'm getting around 8h. battery life

really enough juice for me
Hello, i am a engineering student and i am very happy about my Battery life.
I Use my P-605 to take notes in the university.
For example, on a day with three lectures.
First Lecture, i use LectureNotes to mark something in the PDF scriptum and write down a few notes.
Second and third, creating a whole Entry which causes that the screen is nearly 95% of the 1,5h Lecture active.
After that, driving home with the bus with listening to music and checking facebook and xda.
The Energy saver made was enabled (because it was implemented for Such reasons) and screen on Auto (+0, +1).
After that day, 70%, not bad, or not?
I used some of the tricks mentioned here in an xda threat to increase the Batterytime.

That's about what I get of screen on time.
At this exact moment I'm on pace for about 9 and a half hours with 2 days on time
Sent from my SM-P600 using Tapatalk 4

8-9 hours screen time is what mine gets. This is with a 1 minute time out and 20% brightness. If you use the default 30 second time out and auto brightness, you may be able to squeeze out another hour or so.
Go by screen time and not total uptime. One person's "heavy use" is someone else's "casual". I'll use the Note for 5 or 6 hours straight. That will get me down to 30% or thereabouts. As such, I'll never get 2 days out of it or an iPad.

Playing any type of game, even ones that aren't graphically demanding like clash of clans or plants vs zombies 2 drains the battery very very fast, i could lose 50% in 2-3 hours.

Just about hitting 8 with all the extras disabled and just browsing the web and youtube

Impressed with battery life

I have been impressed with the battery on this phone the last few days. Now that Im up and running with all my apps I gave it some good tests the other day.
On my note 3, while driving with nav and music streaming from google, I would lose about 8-10% an hour.
This weekend I did about 5 hours of total driving, with nav and music on the whole time. With a few phone calls, by the end the of the day, I was still at 46%.
Last night I tested just music. I had a 2 hour round trip. (Hour there, hour back, all highway and the same route, so cell signal would be the same)
Driving down, I started at 80℅ and arrived with 76℅. No music was playing. Phone was ideling.
On my drive back, I started at 75% and ended with 71℅. Music streaming from google the whole time.
I will be testing more, but that is pretty damn impressive in my book.
I will post my settings and turned off apps list later.
Attached is a screen shot of battery use from this weekends driving.

I agree completely. I didn't have the note 3 but I did have the note 2 and this battery dominated it. And the Fast Charge is amazing 50%in 30 mins. WOW

As am I
I am VERY impressed and HAPPY. Coming from an S3 that would be at 50% by the time I got to my office at 9:30am. Granted I am up early and our work starts the same. I am handling everything first thing before my trek in. Anyway, yesterday I awoke to a full battery and decided to try it out. GPS, calls, email, normal business day type stuff. I had 12% left by the time I fell asleep. NIIIICE

Its 2:20pm here and I'm at 62%. My Note 3 would be about 30-40% at this point.

I'm not that impressed. Don't get me wrong, it's way better than the 4 hours I got on my S4, but I am a seriously heavy user, and I only get about 9 hours before I need to charge. It's largely because my brightness is at 100% but I expected a full day of usage between charges lol

I agree. The more I use the Note 4 the better the battery life "seems" to get. I don't know if it's just settling down or what but it does seem to have improved over the last couple of days.
