Why do we got the problems with our BATTERYs ?!

So... I was wondering... WHY DO WE GOT THAT PROBLEMS !?
If we take the NEXUS S Rom and convert it for our PHONES (GT540), where is the TRICK ? Why do we get that problems with the battery and te NEXUS S users not ?!
NEXUS S got the same battery like GT540 and after the GSMarena compare, the GT540 takes it much better then the NEXUS S !
CAN someone explain it maybe ?! Cause I really dont understand

Its the rom itself not the battery.

I know that thx for the reply... But where is the TRICK, why is the ROM quilty for that probs, why is everything else working just perfect and just the battery not ?!
Im sry for that topic and for that question, but Im gonna sell my phone cause of the freakin ****ty battery lifes on every better ROM

Well the rom has a file with the battery calculator. And this isnt calibrated right for all roms.
Also most roms are still under active development so dont get your hopes up about good battery life etc etc

I think battery problem have something with kernel, on 2.1 i use 4 diferent kernel (orginal lg, 666 infernal, quarx, pcfighter) and every kernel have diferent battery life, diferente dischargin steps. So... no orginal kernel no good battery life.

THX for you answer !

I have a Nexus S. The battery lasts 1 day If I use .It is not overclocked (yet) . The battery is same on gt540 it lasts 1 day if I use it.See the attached screenshots from my Nexus S.

What I usually do is that after the battery is charged to 100%, I reboot the phone in recovery and keep it plugged in and charge for anther 15 mins. That seems to give me an additional 1 hour as my phone stays at 100% for at-least an hour before falling back to 99%.

I have had my phone off charge for 5 hours and its sitting on 95%.

Really god i need to invest time in re calibrating mines shocking 13hrs then it died

Battery depends on few things.
1. Kernel
2. Rom itself
3. It will drain faster with data on.
4. Some crapy apps kill your battery.
Choose kernel and rom wisely. Turn off your data if you don't need it. Uninstall unnecessary apps

FOR all those WHO GOT the same problem like me...
I fingered out how my battery is holding for 4 days now...
When you plugin your phone into charge mode... just dont let it to go into "SCREEN OFF"... make your Screen OFF to 30minutes and just hit the screen every 25 mins... or just install an app which doesent allow your phone to autoScreenOff it
After this lil trick... it just works for me now... I hit 113Hours with this trick on Muraiks M6 Version !!!!!!!!!

You don't need an app You need to go to development settings and click never sleep on USB. Thats what I do

Battery Drains QUICKLY!

I got school at around 6 am. By the time I eat lunch it's already at 57%. By the time I get home around 5 and it's already at 17%.
All I do is listen to music (doubletwist/playerpro) and play Cut the Rope, WTF!?
Cell standy by is 46% in batter usage followed by wifi with 11%
any help guys?

What I tend to do is have brightness down to about half. Have you also tried fully charging the phone, taking the battery out and charging back to full? I sometimes find it drops down but regenerates itself.

Brightness is below half,I never go over. WiFi is on but not all the time.
Stock rom 2.3.4 rooted

Do you have data off?

How's your phone signal most of the time? It has been proven that low/bad signal drains battery quicker than good signal.
Sometimes certain buildings/rooms have pretty bad reception making it a huge drain for your phone.

This is a useful piece of information, however is not really practical. Ideally we don't want to be turning off our phones on every charge :/
I myself own 3 batteries, and alternate them (I have a wall charger for the batteries)

what ver are you using if 2.3.4 the battery issue is fix.

I get 3 /4 bars, at school right new and yea some times I get nothing, especial ly during the subway ruse which is an hour

Once I updated my phone to 2.3.3 I noticed that the battery life was sub-par, only lasting 3/5s of the day on a full charge.
I proceeded to root my phone (as I don't have the money to unlock my Big Red Bootloader); after installing SetCPU I took down the clocking meter 1 notch (768MHz) and the phone is stable with not difference in performance (so far). Doing this and removing some unneeded bloatware has increased my battery life 2.5x and I can go almost 3 days on a single charge.

xiEvo is correct and I've read a lot of good stuff regarding battery life with 2.3.4. I can only begin to imagine what kind of battery life I'll have once I get that update.

get juice defender off the market ultimate version is best. this will lookafter everything for you.. juice defender is a must have app for all android devices
Sent from my R800i using xda premium

I'm 2.3.4.
Honestly I had the best battery life with 2.3.2, IDK why.

Someone help me! (BatLife woes)

Alright I wasn't going to make a thread on this because this topic is already discussed elsewhere naturally but I feel my situation is different. All over the place I see people reporting great battery life with ICS.. well mine is HORRIBLE. I just flashed the latest nightly for Pete's bugless. I didn't change the kernel. Everything is stock. Only a few apps installed. Noop for scheduler and ondemand for governer.
The phones been off the charger for 55 minutes and I'm sitting at 76%. Idk what's going on. I've tried so many rom/kernel combos and I seem to get the same exact battery life no matter what. Around 6-9 hours with less than 1 hour of screen on time.
Things I've tried to combat this:
Undervolting
Freezing apps
Restricting background data
Underclocking
Brightness set to auto
And I'm sure a few other things I'm forgetting about. I've done all this and still get ****ty battery life. I've flashed the new radio hoping that it would solve my issues but no dice. My signal strength reports at -67 dbm yet the bars never go over 2. 3g or 4g. Even after updating plr.
On gingerbread cm7 I ran brightness at 70%, ocd to 1.4ghz and always got 15+ hours.
For the love of god someone help me. Cuz I think my phone hates the cream sammiches.

try this kernel, trinity teuv underclocked/undervolted kernel, oc'd gpu http://goo.gl/rY6ga
and do not set brightness to auto, its a battery killer. i keep my brightness at about 20-25%.
also, be sure to fully discharge your battery then charge it completely, after 2 or 3 cycles you should be good.

I do this every day lol I let the battery drain to around 15-30% before I plug it back in.
Screenie: 1 hour later and I lost another 25% this can't be rom or kernel related. As I have tried trinity already and the same thing happens

Ugh. Another 20% gone. Its only been a half hour from the above screenie. You guys see my dilemma? Lol **** me.

i was having horrible battery drain after flashing a new rom & kernel - i finally figured it out that my APN settings were messed up and I re-entered them according to the correct carrier settings.
i don't know if that will apply to you since it looks like your 4G data is working properly, but since I was on wifi 99% of the time, as soon as I went off, my data didn't work. but it's something to look at.

4 hours later I'm down to 4% from a full charge.

Could you try better battery stats to see if something is holding a wakelock?

Turn Data usage off :/ i think Fb or some app is using your 4g

I would be interested to see what your battle life diff is without 4g switched on. Also in that 4 hrs what was ur screen on time?
Have you thought of trying a new batt? Just got an OEM Samsung for 5 bucks on eBay. Worth a shot.
Oh remove fb app it blows...install friend caster way better less batt make sure you change the sync interval.
You could also try green power from the market to manage your data use while screen is off.

Ok here's how my battery performs back in cm7 nightly 174 gingerbread. Almost 4 hours and only 25% chipped away. If you look above you'll notice I lost more than 40% in the same time with ics. And I'm doing nothing different. I'm even overclocked to 1.3ghz ondemand with noop for a scheduler.
I think I'm sticking to gbread until official source is out. Maybe then ill get the same battery life.
Sent from my Nexus S 4G using xda premium

That is really weird, if you have time try Milestone 3 and SG's latest kernel and just leave the settings stock . I get wonderful battery life with it hopefully you do to
Oh and are there any apps you are using on ICS that you aren't on CM7?
Sent from my Nexus S 4G using XDA App

Nope. Lately its only been a handful. I actually have more apps installed on gbread to achieve some of the features that are baked into ics. I just don't get it. Ics hates my phone. I even used the GPS today. So weird.

This. If you are installing the same ol battery-draining POS app then you are not going to fix it with any rom or kernel.

So you guys think my batter watcher widget is preventing my phone from sleeping properly? Ok.. I'm on cm7 right now. Battery is def back to normal. And this is with bacround data on. Ill delete bw and get better battery stats.

Better battery stats is not the same thing as other (mostly useless) monitoring apps.

Look. 16 hours on gb. If none of my apps are killing the battery then what could it be?

Bad battery life after rooting and istalling a rom

Hey guys. I recently rooted my gt540 for the first time. Everything went smoothly, i installed a rom with fastboot, installed clockwork recovery and then the problems came. I installed swiftdroid 2.3.7 and i noticed the battery was draining too fast. The only thing that was on was wifi. I dont even use a sim in that phone. I left the phone at home and when i came home 5hours later it turned off. I thought this rom was to blame so I installed polish blood beta 6 ics rom. When i'm using the phone the battery is draining very fast. And also when i plug it in it is recharging too fast. It goes from 40% to 60% in a minute. Before I started installing these custom roms my phone could last weeks in standby mode with wifi on. Does anyone know the solution to this problem? Thanks in advance

You have two options, first from the android market download battery calibration, charge your phone to 100 % or when phone indicates "charged", run battery calibration and click calibrate, it will remove battery stats from the system (you need to do this every time you flash a rom, the second method, after your phone is fully charged, go into clockwork recovery (power + home), choose advance, and choose remove battery stats to remove it, restart and enjoy, hope it helps!

Our phone is not suitable for later versions on android,tha one you mentioned are roms which eat a lot of battery.......if you are lookin for battery performance switch to 2.1 roms.......
Sent from my GT540 using xda premium

So then it's not just my phone. But it seems illogical that it drains so fast. If I used this phone as my personal device it wouldnt last me even two hours of active usage. What's the point of these ROMS if they cant get you at least through the day?

that always happen to me too ... deleting stats isn't usefull ... maybe it's a battery problem ... my battery isn't perfect but it can make about 2 - 2.30 screen on time and a total of 14 hours all sync active ... a newer battery could give me probably some more juice

Yea same result running matrix so I think its the battery
Hopefully.....

using straight aosp 4.2 with any kernel gets me at best, 5 hours of standby time. I noticed this about a month ago and immediately started looking for ways to prolong my battery life. What seems to be working best for me is disabling mobile data when I'm not using it. Just this one setting gives me a boost from 4-5 hours in standby to well over 12 hours of normal use (of course, with the exception of any web service). I have come home from 13 hour shifts and still had 30-40% battery left several times!! However, this only happens if I disable mobile data.
Something needs to be done....and QUICKLY!!! My phone is pretty damn well useless for anything involving internet connectivity unless I'm using wifi
btw, my battery is about 14 months old.

I'm pretty sure the battery drain is from 4.2, when I was running 4.1 I had no issues
