Impressive Battery Life?

Hey everyone, I have now had my Nexus S for 3 days and have loved every minute of it.
One of the things that has surprised me is the battery life. Check it out:

I still have 39% battery after two days! This is really amazing I think. Granted I only had 2 phone calls in that time but I have been texting a lot and playing around with settings.
How long does your battery last and do you have any tips on improving battery life?
I am running CM7.1 with Go Launcher Ex and have the brightness set on very low plus I don't use screen orientation switch either.

What is your screen on time?

I use matr1x kernel wich has the best batterylife for me, but i still have to recharge every day...

I run it completely stock and unrooted, and get about a day with average use. By far the best smart phone I have owned.

Matrix or Trinity seem to give the best battery life.

Sorry I don't know how to find screen on time.
I put my phone on charge after 2 days 22 hours and it was still on 19% but I charged it to be safe because I am expecting a very important phone call.

Calculating data regarding battery stats using morfic TEUV-S22-05102011, you could reach around 80 hours with cell connected but having very little activity.

Same place as that pic but click on display that will have shown display on time

How did u do the screen shot unrooted?
That's still impressive battery life.

For the people on matrix or trinity kernel, how long is your battery lasting you off charger? And how heavy of a user are you? Just curious been messing around trying to get it over a day :/

Hey everyone. Here's a screenshot I took of my phones battery use. I was just wondering if this rate of discharge is normal. My screen brightness is always let to the lowest possible, all power saving settings enabled, phone overclocked at 1.6 with ondemand governor. I am using the sensay XE35 v 2.1.0. How could I improve battery life, any help is appreciated. Thanks in advance.

Screens of the battery use screen would be very helpful.

Did u let ur phone battery cycle a couple times?

Thanks for the reply guys, stabro I've had this Rom for about a week now shouldnt the battery be calibrated by now, or does it need a little longer. And matt, isn't that what I uploaded or is there something else that I need to upload

The screen you were at before you clicked the graph to get what you already posted. It shows a bunch of apps with how much of the battery it's been using.

Oh haha sorry, blacked out for a moment
Here's the shot of that.
I have no idea why it doesn't show actual apps, but I havnt messed with it. I'm assuming its rom related?
Sent from my HTC Sensation Z710e using XDA App

Was your wi-fi on the whole time, and is your cellular service always on even in standby? Changing those can have a large impact. Did you have better battery life on a previous rom? Is it the stock battery, cause if so, the life on it is typically not very good.
I've found in all the Sense roms I have used, display is always right at the top in battery use. I would normally have mine at a set brightness like 45% during the day and 25% at night which would drop display usage a bit. Plus try underclocking instead of your overclocking to 1.6.

That might be because you had plugged it in for a few minutes. It shows the battery usage since the last time it was disconnected.

LBN1 yeah I always keep WiFi on, my phone is always on 2g mode. Before this Rom I was using miui, the battery on that wasn't the best but it would see me get through the day with medium use, and prior to that, ARHD by far best Rom for battery imo. Yeah I still use the stock battery, though I'm thinking about buying another battery.
I've read somewhere, cant remember where lol, that a low signal uses a lot more battery as its constantly searching for a Signal, I think u guys have noticed from screenshots that my house, has very bad reception

Do you use your phone alot? I am gaming alot on the phone during schooltime, and it DRAINS battery (1% per minute almost) And I usually charge my phone when I come home again. And what kernel do you use? I use Bricked 1.6 beta, and it's awesome (1.5ghz ondemand)
Some things that helped me a bit was:
-Calibrate battery
-Undervoltage (download system tuner and hit 6 times on the -12.5v button)
-Juice Defender ultimate (It works really good for me)
Hope it helps

Not sure if this is right for what I use
Sent from my Sensation using xda premium

If you want better battery life, I can suggest a few things.
Buy a better battery, flash a non sense rom(sense takes up a lot of battery), shut off your gps, turn down your brightness, if those still don't help, there might be a rogue app in the background . Use system tuner to find it.

What like cm9 I was on fence I guess I will try it bright on auto no money for battery

I find this hard to believe. I've tried all three, non-sense, sense, and AOSP. I get about the same battery life (screen on, max brightness, active use; 3.25 hours). That's whether or not I strip most of the useless applications out.
Anyway, OP, best I can tell you is to remove that Sense 4 rom. Seriously, they're not 100% ready for our phones and may never be. Any instabilities or issues you have using them are your own doing.

I disagree that Sense takes up a lot of battery. I've run AOSP, Sense and Senseless ROMs and to be honest, they take up about the same amount of battery. But yes, turn down your brightness (don't use auto-brightness) and try another ROM. I've generally found Sense 4 ROMs to have greater battery drain, which I believe can't be helped at the moment considering that they're ports and the devs are still working hard to make them stable/smooth.
I've got stock battery and I can definitely get more than 12 hours with moderate use.

you should disable automatic brightness if you want better battery life, but there is really something wrong with your sensation, try to install the newest firmware and do a full wipe and a new install of the rom you prefer.

Battery Life and Radios

So I get terrible battery life on GB, ICS, an JB compared to my Nexus One.
Tried almost every ROM + Kernel combo now and no use.
Turned off every battery draining thing (Data, Wifi, Bluetooth, NFC, GPS, No widgets, No fancy wallpaper) and yet my battery goes down like 20% just being in my pocket for an hour to two hours.
In that same time I would lose at most 10% on my Nexus One.
Could it be that I have a bad radio? Do you guys who seem to get awesome battery life have a newer radio than I do?

Have you turned off the google auto-sync? You can do so from the power widget.

Yep. I have everything related to sync off and I also have backup data off as well.
Is 9% battery loss in 45 minutes okay with all those things off and it just being in my pocket?

You need to use better battery stats to figure out what is draining your battery. You can find it here.

Install cpu spy. Maybe your phone doesnt go deep sleep.

Maybe your battery is physically dying.
Sent from my Nexus S using xda app-developers app

Yes, there are many things that can adversely affect battery life, and radios are on of them. You can try to flash a compatible radio, but make sure you have a backup. Also, all radios eat battery when they're in bad signal (the phone uses a lot more power amplifying the signal).
BUT
Battery drain can be caused by many things. So while it wouldn't hurt to flash a new radio, you should still monitor the drain with betterbatterystats
Sent from my Nexus S using xda app-developers app

Assuming the OP didn't switch on '2G only' in the settings I'd be inclined to suggest that flaky 3G signal is the cause of his battery drain. I'm on the newest radio (XXKI1) and whenever I'm in an area with poor 3G coverage (the inside of my house, for example) I often fall prey to horrible wakelocks. Switching to 2G only (plus WiFi for data) solves the issue.

[Q] dissapointing battery life on Paranoid Android Beta 5

I have kept the screen brightness at the lowest of the low, only turned on data when needed, and still my battery can't have more than 2:50 of screen on time before the battery dies (1%). I am assuming stock rom is most likely the best for battery life, but I require some custom features that only non-stock roms have. So what I am asking is, what else can I do to improve the battery, or what other roms have good battery life for Nexus 5
Thanks

Use better battery stats to identify wakelocks / wake ups etc

You also need to examine wakelocks and hungry apps...d/l and use a wakelock detector and try to forego the top 5 apps that waste the most. (eg. Facebook?)
Damn..beaten by rootSU again!

roms dont really have anything to do with battery life. kernels do somewhat, but to a point. battery life is mostly affected by how you personally set up your phone, what apps you chose to install, how you personally use your phone, and mainly the quality of your phone/data signal. remember, as many phone users as there are, as many different ways that people use their phones.
