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 :/

My understanding is that the battery drops fairly rapidly from 100% to 95% before stabilizing to a slower, more controlled drop
I think this was detailed in the Synergy ROM thread

It might be because you are in cell standby a lot, are you in a low signal area majority of the time? Checking for signal 41% of the time, might account for the battery decreasing so fast.
It also seems that the international phones are getting a firmware update to address cell standby battery drain, but I don't know if it pertains to us in the U.S. http://blog.gadgethelpline.com/samsung-seeds-firmware-update-fix-cell-standby-battery-drain/

No, usually most phones will charge to 100 then stop charging and let the battery drain a little, many phones down to 90 then recharge again. That way it doesn't harm that battery.
Now personally I always preferred trickle charging where the phone pulls just enough that it doesn't drain at all, but there has always been debates on if this destroys your battery faster.

Hmmm maybe cuz my wifi was disabled and it kept searching for 4g. This was the first time it happened.

During the night your phone charges and the drops to about 90% then up again. That is normal . Nothing to worry about.

Battery issues

I'm getting pretty horrid battery life. I'm not sure what to do to help improve? This is with brightness as low as possible. Screen time is 2.5 hours. Battery saving is on for everything beside regulating cpu speed. Rooted but with stock Rom.

There have been a few people who complained about this. It seems to be a problem with some of the phones. If this has been happening since you got it out shortly after, then it's probably the phone or battery. You might need to unroot and exchange it. Using battery tips or programs will only gain you about 10%.

If you're rooted try CPU Sleeper: https://play.google.com/store/apps/...wsMSwxLDMsImNvbS5ldWdlbmUzNzMuY3B1LnNsZWVwIl0.
It turns off one of the cores while your screen is off, which should help standby time.
Using a non-stock rom and kernel can also greatly help your battery, but it seems as though you want to stay stock.
Lastly, how's your signal? That's all I can really think of that would cause the S3 to have bad battery life. The S3 usually lasts a pretty long time.

Try GSAM battery monitor or Better Battery stats to find which app or service is drawing your battery. I've seen in other threads where giff_daemon and media server is causing lots of wakelocks and draining people's batteries.

Turn off sync, mobile data unless your actively using it, flash some other ROM and run Imos .07 kernel(aosp) or Kt747. Check what services are running. Freeze or disable ones you don't need.
Want mine to look like this unless I'm running an app.

Manually sync check everything.

Let not recommend custom rom/kernel etc.. Stock S3 should be very good on battery. You should find out exactly what drains your batter by using battery stats. Also enable battery saver mode and auto brightness. Turn off data sync, 4G, wifi, blue tooth and GPS (only turn them only when you needed) and see if it improved. Between using battery stats and turning off all the high drain options, we should able to pin point exactly what the draining source. A normal usage with stock rom, you should able to get around 4-5 hrs of screen on for normal usage.

Try setting up juicedefender, if you don't use your phone that often and battery still drains it will help. I use it at work since I don't use my phone, I have the ultimate version.

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

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.
