battery life

my battery just about lasts a day with small usage, when i click on whats using the power its 46% cell standby and 47% phone idle, 5% android system and 2% display is there anyway of bringing the cell standby and phone idle percentages down? or is this just the wildfire and battery which is supplied with it? got the phone brand new and been using it for less then 6 months?? thank you for any answers

Here's a little info I found earlier about an app called autostarts and also taskkillers, I've been using autostarts for a while now but just saw this today.http://forum.xda-developers.com/showthread.php?p=17236867
There's a few other things you can try to save a bit of battery life like calibrating your battery by wiping the stats from cwm when its just about flat then charging till full, never read a guide on this but I presume that's how it works (someone correct me if I'm wrong), there's a free app from the market I use called llama which can be setup to switch off wifi,GPS etc whenever the screen goes off or to use location to switch on wifi in a specific place etc......

Battery problem

I'hv flashed cm7 last week. The problem is that my defy battery drains too fast as compared to stock Froyo. I have calibrated its battery correctly. Also phone always remains hot. I am looking for solution but didn't get proper solution. Plz help..
Sent from my MB525 using XDA App

I've noticed the same, since flashing CM 7.1 my battery will barely last the day, I don't think it's going into deep sleep.

I'm having the same problem

When I flashed CM7 the second time recalibrated and deleted battery stat battery life improved...now i get about 35-40 hrs on one charge.
But of course there are many factors that contribute to battery life and our devices won't be the same.

Not proper solution yet..

I had problems too but after the Calibration the battery works just fine.. try Calibration again

Thanks to all..will post after getting my problem solved.trying cm7 stable..

I tried cm7 stable..here battery is draining more quickly..is there any ROM for better battery performance..?
Sent from my MB525 using XDA App

can you give us some numbers and specifics about your usage ? its not possible to give any view point or explanation till we know whether you are running on 2g or 3g wifi on/off etc etc .

that your phone remains hot can be caused by two things (in my experience): your cpu is always on 100%, or your gps is on. First of all, try wiping battery stats from recovery when fully charged, than let it discharge. secondly, try using setvsel to control the frequencies. if your battery still drains fast, check whether its water damage indicator is red (the - originally - white sticker near the battery pins), cuz mine is red, which means it was contacted by water, which couldve caused a short, and till then my battery drains much faster.

You can use cpu spy from market to see what is your cpu doing and the times for each state. Check if it's going to deep sleep.

I always keep my GPS, wifi off.
CPU is undervolted at minimum values as 300-16,600-26,1000-46.
I've already calibrated battery.
My battery statistics are: (approx.)
Display- 40%
Android system- 10%
Phone idle -15%
Cell standby- 10%
Android OS -5%
Remaining- other apps
Display is taking 40% while I always keep it at minimum brightness.

I finally got solution.. My defy's battery performance improved a lot. I have installed wakjiui ROM and calibrated the battery and it was unbelievable. Using it since last week. Almost doubled battery performance. At night it drains by only 2%. And one more thing about wakj ROM is it is perfect combination of miui and some apps from cm7. .

i got 48 hours.. sometimes more using MIUI .. highly recommend you to use it!

It is based on miui.

Battery Drain Problem

So I bought my ATT GS3 out in Los Angeles this summer and then I returned to New Jersey to find that I have horrible battery life. It was not right away so this could be completely unrelated. As of right now my phone is at 75% and I let it drain while i was sleeping for 10.5 hours. I have tried several different roms which are usually good the first two days and then after that the battery life is bad again. I thought it may be some application I have installed so I removed a few of the ones I remembered downloading since I got back to NJ. I also updated to the latest radio ending in H9 because I was two behind when I checked. I have attached some battery information below. Any help anyone could provide would be great. I have tried Juice Defender which did save some battery life but it also caused a problem where I couldn't use the internet for 10 seconds after I wake the phone.

U need a Rom with cell standby fix
Sent from my SAMSUNG-SGH-I747 using xda app-developers app

I thought the cell standby problem only effected the international GS3? If the cell standby fix was the problem then I shouldn't actually be draining that low right? Something must be draining the battery then. Google maps is probably draining the battery but how do I stop that from happening?

No its not just international and it is cell standby using almost 10% battery

try Triune ii or Black jelly 0.7 i tried them both on my s3 these both hav good battery backup..

Ariel 2.10 fixes everything!

I just installed the standby fix and im going to test that and see if it helps. If that doesn't work I'll try the other roms everyone has suggested. Will take a little while to make sure whats good and whats not though. Thanks for the advice.

Just another observation. Battery tends to drain faster if you leave it in your pocket. If you flash a rom, you might have to calibrate the battery stats. I only lose 1% every 2 hours overnight if I leave it on a cold surface.
Sent from my SAMSUNG-SGH-I747 using xda premium

So I have tried a few different roms and I'm still not happy with the battery life. I calibrate the battery after every rom installed and I usually keep that rom for atleast 2 days to test it. Right now I'm on AOKP. If the phone is on standby whats the general %/hr? When I go to sleep my phone drops from 92%-75% for about 10-11 hours (on desk at temp 60F). By Apocalypse487's response I should only see a drop of 5-6 % over night when I see 17%. Am I supposed to me losing this much battery life over night? To me I feel like I barely use my phone. Today wasn't too bad with 1 hr with screen on and about 1 hr in calls. I made it about 1 day 1 hour 36min on battery. My phone was sleeping for about 23.5 hours. Is this the typical battery life or is something wrong with mine? Tonight I'm going to try juicedefender and see if that helps.

I'm using ParanoidAndroid based off of CM10. Version 2.16 of PA gave me the best battery life. Try that. Certain Roms have better battery management, but that probably depends on the kernel. PA uses stock.
Sent from my SAMSUNG-SGH-I747 using xda premium

I'll give ParanoidAndroid a try and see what that does. So Juicedefender ended up making it so I only lost 1% over 9 hours. Thats pretty good. Way better than I wanted. So what could be draining the power over night. Is it because my data is on all the time but shut off when using Juicedefender?

I use Trinue 2, and I use an app called Go Power Master.
In GPM you can setup options that will turn off mobile data/gps/wifi when the screen is turned off, will automatically turn them back on when the screen is back on.
Those things little things I find can make a big difference for the battery to last throughout the day.

It's as Sianspheric says, common things like gps, data, and wifi uses power. I just started using Juicedefender since my friend told me it helps. Also download battery calibration. It's a root only app. Don't let your device discharge completely. It's bad for Lithium Ion batteries. That will clear out any bad data from Samsung.

Best thing I have found is to totally drain battery to the point it the phone will only slightly vibrate. Remove the Battery. Put the battery back in and then fully charge with the phone on charge mode to 100 percent. Unplug. Then plug back in a few seconds later for fully charged to reappear. Done. Really helps to do this once every month or two. Credit to someone on another forum for this tip. Turning off data when not in use and low screen brightness will substantially increase battery life. No syncing, bluetooth or wifi will help. An app called GSam battery monitor will identify apps that suck battery. I use longevity by trend micro to shut my data off.

Fully draining a lithium ion battery will significantly decrease it's lifespan. Any positive effects you see from this are probably not measurable, or scientifically reproducible. Your other tip is solid, disabling data (or using an app to do so) greatly increases battery life. As well as turning down the brightness.

Had no idea this practice decreases lifespan of the battery. Good to know. I thought the this resets the phone ability to recharge the battery to the fullest. That's what I thought. I seem to be getting some benefit.

- inverted apps for almost everything that I use heavy.
That's what I can think of right now.
Typically get ~5 hours "screen on".
That could be 12 hours or 2 days between charges.

Battery lifespan for lithium ion batteries is measured on how many cycles its been through (hits 100%). If you go from 90% to 100%, you just used up a battery cycle. Even 99% to 100% counts as a cycle.
The method you described in your earlier post is for conditioning your battery, it works on older batteries but is not needed for lithium or poly lithimer batteries.
Tips for battery life, disable radios and keep screen dim. A dark wallpaper helps too, white screens are a battery drainer!
Sent from my SAMSUNG-SGH-T989 using xda app-developers app

Get a app that disables other apps that start up on system boot-up or other events. Autostarts its a good app I use. As you all should know dont use app-killers unless u know how and when to use them (READ). Like said keep ur screen dim or on auto if u have that issue like me were ur constantly going in n out at work and find ur phone too dim for daylight. The darker your themes the better battery life. Remember that ur screen is one of the top (if not the top) battery drainers. Data, wifi, gps, bluetooth, auto-sync, running widgets, live wallpapers...if you dont need it on or could live without it, then either turn it off or get rid of it.
Also like said before, lithium-ion batteries dont suffer from memory effect like older rechargable batteries. If you could avoid it, dont run ur battery all the way down. Be free to charge ur battery as often as possible and that way you extend the life of ur battery.

Use the lowested sync frequency setting you can or manally sync. Wifi tether guzzles juice. Live wallpaper is a killer. Make task killing a subconscious reflex. The smaller the number is next to "running in background" also makes for more time away from an outlet. Of course these may not help any one else, but it works for me

Fully charge 2 batteries. Unlimited talk and text. True story

I run the ParanoidAndroid 2.51 rom (10/24) with the KKO kernel and it goes pretty good so far. It may be the first day of using it but I will expectedly average 20hours of use on it. (using the live wallpaper phase beam the whole time). Used the wheatly governor with SIO and changed the max cpu to about 1028 so its only using 1Ghz. (seem to get decent battery life)

[Q] Battery Issue

So here's my problem:
About few weeks ago, my battery started to fooling with me. When I use it for Facebook, Twitter and normal web surfing, the battery goes down, fast, from 100% to 10% took only about one hour plus. Then I left it aside. Check it again after 30 minutes, the battery went up to 27%. So I think battery was miscalibrated so I tried to calibrate the battery using all the guides I can find on the net for weeks but none worked.
So what should I do? Should I change a new battery?

Did u try calibrate it properly, eg.. wait till its charged fully then wipe them. using an app from playstore is the best way. If u wipe stats when its not charged100% then it will start jumping percentages.

Standard batteries are terrible anyway. I couldn't do without my 3600mah one now.
As wedgess said, get an app for calibration. I use 'battery calibration' (simple enough) which works perfectly for me

Well try to underclock it and make the screen brightness lowest. Try to look at the battery stats too as you may have an app which is using a lot of resources of your phone. If you can live without your phone then switch it off completely, try to find the charger with highest mAh output (the higher the mAh output is the quicker it is charging), connect your turned off phone to the charger, make sure it's charging, leave it for 2 days charging like this and then disconnect it, boot it straight to the recovery, wipe the battery stats from recovery. If this is not going to help then I seriously have no idea what else you can do.

Phone's not overclocked, brightness is always low, I used it for texting my gf for whole day, played word search for a while and my phone left 50%, no data no WiFi nothing, When I turned on WiFi and keep using it, battery drops fast. Reached 4% I left it, went back to 16%, continue using, left 4 % again, left it again went back to 10%, then I used it till 4% again, now left 6%. Using stock charger but with different cable since my stock cable is broken. Is that related? If yes I'm going to get a new charger.
