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.

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

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 :/

[Q] The screen really uses this much battery?

I'm at like 70% battery and 25% of what's gone after 6 hours is the display, having only been on for 25 minutes total? One fifteenth of the uptime accounts for 25% of the battery loss. That makes no sense...
Is there a good way to reduce battery usage by the display? I'm running at what looks to be about 10-15% brightness, not automatic...

You're on target to get an hour of screen on time, but 24 hours total charge time. You just need to use your phone more It's probably not deep sleeping properly. Try signing out of Latitude and anything else that will wake your phone randomly... email, or facebook updating, etc. Disable background data, maybe root and setcpu and underclock/ undervolt
I came to this phone from an Epic 4g thouch, and the battery life is literally half of the 4G tocuh... kinda sucks. I blame LTE.

I'm not complaining about the battery life as a whole. That's not too bad at all, I'm more confused as to how that much screen time really constitutes the majority of my battery use after 6 hours...

Im in just about the same boat actually, 78% remaining, 36 min screen on time which is 78% of my battery use. 5 hr 9 min

Well thats actually a good thing. The more screen time takes of battery, that means everything else is using less. On the 4g touch some people have 30-40% android system useage and their phone is getting like 7 hours out of a whole charge. You want display high, because when it's on, everyhting is working. Everything else should be sleeping when the screen is off.

Is that an ICS ROM you are running?

Battery usage critique please!

Hi everyone,
Phone is Sensation XE.
ROM is Virtuous Insquisition 4.0.2 (using kernel that comes with the ROM).
I think i'm a moderate user. I dont surf or play games that much. I do text/chat quite a bit. However, my battery can never last a whole day.

Can the phone last the whole day with Mugen battery? I've already purchased it. waiting for it to arrive.
Please advice,
Thanks

Yes it should get you through I bought the anker and it works perfectly no issues but I wish I could still get more juice because I am an extreme user lol...
Swyped From My Sensation.

I'm also an extreme user and anker battery helps a lot! What a difference from stock battery!
Not sure about the mugan I've never tried it.I'm sure it will help out a lot I know Anker does.

If you have all those apps up and running they will withoud doubt kill the battery life
The other poster are correct in that a better battery/larger capicity will provide considerable help
Are you aware that Wif uses lots of power looking for and trying to connect to wifi, so if its not connected switching this off help, also GPS is a grat battery hog and should only be on when needed
try without them on for a few recharge cycles and see
I recommend a quality replacement battery - try the Anker 1800 ma I get almost 48 hous of medium us - no GPS and wifi only on when I'm at home or work - it uses less power when connected unlike the GPS

battery dead?

Hi,
You should use your battery for 3 or 4 cycles (charge/discharge) before judging it.

Yes above post is correct. Please cycle 3-5 times before judge. I just received a. New mugen 3500mah battery
It's recommended to cycle 4-5 times before it reaches full capacity. I'm on first cycle. So far a hour of use still at 100%.but it won't be to full capacities until its cycled at least 4 times.also I read not to drain to zero percent before next cycle. Hope this helps out.also you can get a long lasting battery if issues still persist. Personally I finally broke down and got a mugen 3500 mah for my device. The back cover is pretty ugly but so far first cycle battery is amazing! That's what matters to me anyway. Phone may look a bit pregnant but great battery life is the trade off . So far its worth every penny. I was tired of having battery issues. If you do decide to purchase one. Purchase from mugen site. Also follow instructions before use device must be charged 12 hours even if showing 100% also instructions recommend never discharging to zero before next cycle of 12 hours . I hope this helps.
