Okay...?
The majority of the people here have rooted.

It won't help. I have deleted the batterystats on mine phone more than 20 times in the last 3 days and there is no change nor hope!

Let me rephrase by saying your ROOTED phones battery stats might be lying to you.
And for the guy who tried it three times and failed. I don't think you took the time for fully discharging the phone. That's right I'm calling BS.
Anyway got to go my battery just dropped 30%

Just wanted to let you guys know that this is completely true in my case. The other night around 2am I went to sleep with the battery around 68%. When I woke up 4hours later for work my phone was turned off. I then plugged it in and my battery was at 0%.
I was on the perfect storm Rom. I then switched to das bamf. Still happens. Tried bump charging and 0-100 charging and its helped but when I reboot the phone the battery shows about 7% less then where it was.

I think that is thy the stock battery icons don't show an exact %, b/c they haven't been able to make it work right. Don't worry though i believe that the devs will get it before HTC.

Ok my battery was just now at 50%. I restarted and now showing 41%. I don't know what's going on.

As I said, you can charge and discharge all day long, it won't help!

Thank you for reposting this. So sick and tired of people complaining about dropping 10% in a few minutes after a full charge.

I think this is a glitch. It drops like crazy after restart but then stays there until it "catches up" I guess.

So far,I have only rooted my phone, not a custom rom. I either have a crappy battery life, which seems better when I shut 4g down, or there is a glitch on the metering. My .02 worth.

My battery life!

I'm having a great overall experience with the Inspire 4G w/ CM7. Just wanted to show you guys some screenshots of the battery life I'm getting so far. These shots I took after a day of heavy usage, including a few hours of net browsing, texting, and e-mails.

Hey try using juice defender or current widget to exceed your current battery life. Both control which apps that are eating up your battery. Kills the non needed ones.

i've seen all the complaints about battery life but i must say mine is more than adequate. maybe because for the first 4 days i had the phone, after charging it for 10+hrs, i ran the battery all the way to 0 (til it shutdown), recharged to full, then drained it again.
it was my old habit from my nokia days.

Yeah, to be honest, this is equal to or better than the battery life I was getting with my Captivate. I can tell you with an absolute certainty that the battery did have to "break in" for a short period, after installing CM7.
Sent from my Desire HD using XDA App

Its deff better than captivate, 99% due to the screen. I got over 5 hours screen on time in a 16 hour period the other day with my rom/kernel combo with screen brightness at about 40-50%. That's pretty damn good, way better than the captivate could ever get

On my LG Ally i was lucky to get 6-8 hours with just light use. With the Inspire on cm7 i have gotten around 20ish hours with moderate to high use.
I'm still shocked that i am able to get that much battery life. lol

I'm still breaking my Captivate records. I took my phone off the charger @ 7:00am on Wednesday the 20th. I'm now at 15%.

What roms are you guys running. Im on coredroid 5.4. I get about 20 h with moderate use. I consider it to be pretty good. But no way can I get over like 30 h. I don't like to use juice defender or setcpu. Don't feel like I should use apps that override android os. Especially GB is so will optimized and efficient.

I'm on CM7 and only wish I could get the battery you guys are talking about. I just went from 93% to 90% in a matter of minutes doing nothing on the phone. It was sitting on my desk!

Does your phone get lonely spending all that time lying silent longing for your swipe?

Not at all. It's my personal and work cell, so I talk, text, surf, and play games what I would consider a moderate amount. I don't use a large overclock. I use the smart ass governor on Leedroid's most recent rom, and my screen brightness at 1/3.
There are days that I can put it tonthe test, but my first charge got me 35 hours with 5 hours awake time.

That's it? I got this a while ago and that's before I did some optimizations... I'm going to see what it can pull this weekend before it hits the 15% warning.
Apparently I can't add images until I get some more posts.

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...
Sent from my Google Nexus S using XDA App

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

Ok I found it, it says 3hours 24min and 10s.

wow.... 3h 24min display time and still 39% battery? amazing.

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 :/

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.
