Any suggestions about my battery life

I know that there are lots of these battery life threads and i have read most of them and I've tried closing processes that i don't need and i have tried setcpu to keep the cpu low when the device is off, which seemed to help some but my phone would shutoff randomly. So last night i had a full battery and went to bed when i woke up 8 hrs later i was at 20% so about 10% an hr not even using the device. I have attached some pics for reference does anyone have any thoughts that might help. Thanks

I don't know about galaxy S but on my X10 the problem was wifi.
When I didn't have a data plan I had wifi on all day and the battery was down in 10h max 12h.
To improve it I had to use JuiceDefender to enable wifi every five minutes for updates..
Try to disable wifi overnight, reboot the phone and see what happens.
By the way, what app you used for those stats?

I don't have wifi enabled, I don't use it that often. the name of the prog is system panel

Very weird indeed. I have my Captivate with Wifi on all day, GPS signal and auto sync and when I go to bed and wake up, the battery hasnt gone down at all. I had the phone go on full battery one day and I even sent a few texts and went online for 10 minutes before it lost just a bit of battery.

Do you have that one LED app installed? The one that shows a little red dot on the corner of your screen when you have a notification?

yes i do.. Why? but it was turned off last night, as its turned off every night

Ok so i tested again last night and I did not have my im+ app running and the battery life was soooo much better. I also did not have system panel running which records all the battery and cpu stats but i'm think its the im+ app that was taking up all the juice. Can anyone think of another app that does skype and facebook but that also does not take up sooo much batter life??? Thanks

Possible he has his set to stay on. While yours may turn off when sleeping.

Open up the dialer and type in *#*#4636#*#*
Go to BATTERY HISTORY>PARTIAL WAKE USAGE and maybe that will show you which app is sucking up your battery life while you sleep.
Also try, if you don't absolutely need an internet connection while you sleep, SMODA widget to turn off your mobile internet. It's quick, free, and painless.

yeah the app that took the most juice was im+

I drained mine down to 5% and charged full a few times and still only got 8 - 10 hours on mine until i flashed to jh2 and now have been getting almost 16 hours with same usage and apps installed. I charge mine at night. I use ebuddy with the piwer saver option turbed on abd it does an ok job.

I have the stock ROM and stock launcher and my battery is awsome! 8 hours and I will still be above 80%.
Brightness: Lowest (manually control via stock stock gesture)
GPS: OFF
Wifi: ON all day
BT: OFF
GMail manual
Other emails accounts hourly for the most part.
Widgets: Google/Fancy Weather
BG: Mostly Black
I have never seen such good battery life on a smart phone.
I could easily get 2 days, but i rather charge every night and then not worry about battery usage.
The wifi/gmail/gps made a big difference, its too bad you can't set gmail to hourly or something lik e that. Some of my email accounts i would like to set longer than hourly.

The last few days have been pretty good one my phone. Used to get maybe 16 hours but my last charge lasted me about 50 hours with moderate browsing, gaming, and voice/text. Juiceplotter is telling me I'll be getting about 47 hours

How many hours with the display on?
Sent from my phone so I apologize for any spelling mistakes

My battery icon depletes one notch when I'm using the screen for about an hour. Some people recommend cycling the battery, in which you do a full drain and immediate full charge, 3 or 4 times. I've done it, but it's hard to say if it explains my good battery life.

let the battery drain COMPLETELY until the phone turns off a couple times, then charge it till 100% without unplugging it.

You don't want to drain the battery that much, those kind of batteries can be damaged. The phone turns off for a reason.
I haven't done the cycle thing and its fine. A lot of that comes from older batteries with the memory problem.

irus, software which is based on data connection drains the battery one way or another. Some apps now support push notifications and IM+ does too. Did you try to use push?

These claims of multiple day charges with moderate use is crazy to me. I have the newest ROM, a black screen, display all the way down, gps off, wifi on when in range, make zero voice calls, run juice, and only have 2 widgets that update every 4 hours. I use my phone for a maximum of 3 hours browsing the web, reading XDA and feedR, checking facebook and the occasional text message. My phone lasts a total of 12 to 14 hours. My battery has a manufacture date of late July. Is there some secret I am not aware of?

What is your standby drain? I'm looking @ 3.5%/hr.

Mine is more like 7%/hr, which is totally unacceptable, I have all sync turned off, except exchange... with my HD2 running Froyo, I could do 2%/hr with the same settings.... I am still trying to figure out what's draining my battery...
I have also noticed high data usage.. I've tracked it down to T-mobile's AppPack. I've never used the program but it's constantly draining away my data... Is there a way for me to remove the app or disable it?
Thanks!

Get Watchdog from the Amazon appstore to find out what's draining your battery. I believe it costs, but it is a thoroughly useful app
Don't think we can remove carrier apps until we have root...that said, you could try adb pull, but I'm not sure whether it will have any effect. May need root for ab pull, in which case we can't get rid of carrier apps :/ sorry

its funny how some people report 0% battery drain in 9 hours and other get 3-4% drain per hour.....
please post how many charge cycles you went through, its important.
I am personally using HD2 and battery live is amazing. and its only 1250

this has the best battery life ive ever saw. I'm in 0ma all the time the phone yesterday lasted from 530 am til 7 pm at night with a lot of text and playing games like homerunbattle 3d. If you play that game you know how much of a battery hog it is. Best battery life. Battery was soo good i barely charged it went to work with a 40% battery and it easily made it through a day with moderate texting all day!!

Gotta say... coming from a TBolt this thing is like sex in a tin can.
Idle is 1-2%/hr probably. I would get 10%+ on my TBolt at times... if not more. It was bad.

Seems like I'm the only person with excessive battery drain...at 7%/hr....
Just wondering, when you go into battery stats and extend the graph, does your phone stay awake when the screen is off?...
Mine seems to be awake all the time even though the screen is off.
I got Watchdog yesterday, I didn't notice any apps with high CPU usage...

Me too.. I lost about 8%/hour in 2g standby mode... Totally unacceptable comparing to my previous galaxy s...
Hope next FW update will improve it ..
Sent from my HTC Sensation Z710e using XDA App

today is the first time I'm having issues. Only 4 hours since charge & down to 40%. The Awake time shows as 99% of Up Time. Is that normal??? Also, anytime I look at the task manager it shows wifi calling running even though I have it shut off

I've got an Asian model sensation (ie. 3g and not 4G model ) and I find my battery isn't really calibrated properly so its hard to comment on average percentage drop per hour. I've recharged my battery 3 times already and i find the battery stays at 100 percent for around 30 minutes of constant on web browsing, then it will drop at a rate of 10 percent every half an hour with constant use and will fluctuate.
To report on a rough usage breakdown, with all background syncing disabled, I managed to get 10 hours standby before my phone dropped below 10 percent. This was with 5 hours of screen being constantly on doing mainly web browsing on 3g and one 15 minute phone call using my wireless Bluetooth handsfree.
I can report the battery life with constant usage is better than what i got with ny hd2. Running android ROM, it used to do around 3 hours of constant web browsing before the battery will fall under 15 percent. In standby my hd2 used to drop around 1% per hour, which was quite excellent.

Those are the stuff I'm talking about, it appears that one of the settings and/or app is constantly using the processor, which causes the phone to stay awake even when the screen is off... I just haven't figured out which app is causing the problem.. I am suspecting it is one of the Tmo apps.

I'm looking at a full battery life of 11 hours, 49 minutes with moderate usage (some calls, decent amount of texting, some games). I use the app/widget "Battery Left" to do its own independent assessment of battery usage and life.
So far the battery reminds me of my early days with my Nexus One -- before I had it rooted and optimized and undervolted. Once rooted and optimized, I saw a good 50% increase (at least in battery life).
If you'd like some relief right now (before we get it rooted), I recommend Juice Defender on the market. It turns off data (among other things) every now and then to save battery, and with this I can squeeze out 18+ hours with moderate usage.

how are you checking the percentage? when I looked in the settings menu, all I see is a long green battery bar, no actual numbers. Or are you all estimating from that?
I don't monitor my standby time, but I'm sitting at what looks like 40% after 13 hours of fairly moderate usage during the day, I'm impressed.

Ive been getting about 9 hours out of a full charge. Had to put my phone on the charger today at around 4 o clock because it was dead. I dont have much more info other than that. I will keep an eye on my processes over the next few days. I have only 3-4 cycles on the battery though.

To check the percentage of the battery life u have to download some battery widget in the market.. I.e smart battery monitor or battery percentage s.th like that...

You can also check battery level by opening Phone and dialing *#*#4636#*#* and then select Battery information.

I'm using Juice Defender and I have to say it really does the job : my Sensation lasts More than one day and a half (30min calling a day, texting, Android Market, Angry Birds...). Without the app running it would last a day (Angry Birds drains...).
Juice Defender says it is increasing battery to 1,53% and it is very close from reality.
I've been owning the phone from 24th of May.

That's defintiv much too much.
Look at battery stats in settings - phone-info - batterty - drain (or something similar) if any market app drains your battery.
Did you restore system(!)settings with titanium?
Last exit: wipe everything (eg from recovery - I'm not lbc,so it's not my tool ), redownload (md5 sum!?), reflash - and do not install any market apps for the first hours. Battery drain should be max 1% per hour with screen off.

Did you perform the battery re-calibration that is recommended after new ROM install?
see LBC post http://forum.xda-developers.com/showpost.php?p=14981516&postcount=581 where he corrected the previously written method.
I'd recommend following these instructions and then check battery usage again.
This thread should not have been started here in Development section, but either as post in LBC ROM thread or as new thread in general.

I never ever did such a re-calibration, but perhaps it helps...
Normaly battery indicator is correct after at last 2 days of normal usage (I always plug in over night and never turn off the phone - so seems that it re-calibrates itself)

I had the same problem with lbc 0.5.2. The battery life was like 12 hours normal use.
So i went back to lbc 0.5.1 and everything works fine. Standby time now more then 36 hours.
Maybe this will help you for a while.

Hey, sorry that I don't wrote that I tried this too.
I wrote with LBC about it. He told me, that he dont has the problem.
I also thought, that maybe the value isnt right, so I dont recharged it, but at 1 percent the phone turned off.
With 0.5.1 I dont have any problems.

mine drains fast as well...
I have followed all the instructions for a newbie with android in terms of saving battery life, but I still feel that my battery drains fast than the normal. Here is the scenario...
Full charge @ around 10-11pm, with one hour extended charging.
Turn off wi-fi before sleeping @ 11:30pm.
In the morning, battery is at 99% capacity as per battery indicator. Screen is at 25% brightness.
Turn on mobile network connection upon arriving at work @ 7am, there's no wi-fi in the office.
At about 9-10am, battery indicator is at 52% capacity. I normally use my phone in browsing Facebook, playing a li'l poker before working (my office is secluded), some browsing etc. I don't watch videos on my phone.
At around 12noon to 1pm, I connect my phone to USB charging in my PC, battery is at 25% only.
I don't think this is normal. My best guess is that the network connection is draining my battery, but I have no other choice but to use it. I'm need it turned on while in office to be connected to the outside world...
Anyway to extend battery life???

Does this mean you are connecting to data through the mobile network?
Is your wifi connection still switched on as well?
If wifi is searching for a connection all the time this will seriously drain the battery.

Depends on their sync settings. The battery stats app will show you which is the greatest consumer. If it happens to be facebook, dial back the usage. I used IM+ briefly, but uninstalled it. I can't remember why. I'm not on facebook.

I do the calibration after any flashing of custom rom. And it's allways helps to me, battery live is 2-3 days after this, and 1 day or few hours if not calibrated after flashig new rom.
Android 2.3.5 roms drain battery mush lower, and work faster. Flash it and calibrate battery after.

Terrible Battery life problem

I recently got a new lg g2x. Seems like an alright device (it's not the best out there, but it was free so it'll do). The only thing I can't stand it even with pretty low usage i'm getting around 12 hours of battery life max. With the same type of usage from the sensation I had before I would be getting around 24 hours or more.
Any one got any ideas of what to do? I'm currently on eaglesblood, I was on CM7 latest nightly before, and before that was stock. All battery life sucked though.
Any help would be appreciated. I did order a spare battery on ebay, that i'm hoping might do some good.

What happened to your Sensation?
Have you tried calibrating after flashing a new ROM? Personally, fitsnugly's CM7 Kang plus Faux's or Morfic's Trinity kernel has always given me really good battery life. Around 24 hours with average useage.

I'm returning it via American Express premium returns. By calibrate you mean?
Sent from my LG-P999 using XDA App

Use the battery calibration app in the market after flashing new roms. If you can't figure out how to make your battery last longer, just buy an extended battery for like 12 dollars off ebay. Everybody has had good luck with them. There's a thread over it in the accessories portion of the g2x forum.
Sent from my LG-P999 using XDA App

Alright, I already ordered a spare battery, but I'm not sure what else it could be. I'll post back after I get the battery and try calibrating it.

Just in case you may have overlooked this....turn your wifi off when not using it. Wifi burns goood.

My wifi is always off, although a few times when trying to turn it on when just flashing CM7 it resulted with not being able to turn it on due to some "error." A recent example of my battery drain is: Cell Standby 43%, Phone Idle 32%, Display 16%, Android System 11%.

Calibrating would be my advice. I get a good 24 hours of usage with CM7 with normal usage. I get 30+ with light usage, and this is with wifi set to never sleep.

Everyone that gets 16+ hours, do you have Data running all the time?
Data + Light Use = 8hr MAX
Juice Defender "Data Off" + Light Use = 14hrs MAX
Juice Defender "Data Off" + Medium USE = 8hrs
Only did a couple texting and my battery is at 35% already, and its only been 6 hours...
Battery Calibrate = Flash new rom > 100% > Calibrate > use and recharge for 3 days...

How can I find out if my Phone "Actually Sleeping"?

If it's actually sleeping, then your phone would not have any activity under "awake" while the screen is off. Also currently I'm on 30 hours battery with 33% left.

It show that it's was awake the whole time... the past 7 hours...
When I scroll down it show these that is on the whole time:
Launcher
Telephony Service on and off
Messaging
Facebook
Gmail
Email
Weird though, I have Juice Defender on Extreme.. so there isn't any data running until I enable it.

Well to find out if it's been awake the whole time you have to go in one more menu deeper. You can do that by pressing the graph in the battery stats.

I'm currently exploring which programs are preventing the phone to stay "asleep."
I freeze lots of programs I don't use, the only ones I see constantly active now are Google maps, Facebook, and the launcher (which I hope isn't one of the issues).
I froze the first 2 and I'll be doing tests today to see exactly what it is.
Do you guys use the default MIUI launcher?

Yeah I'm using the default MIUI launcher..
I also freezed MAP and FACEBOOK... see how that goes for the rest of the day.

Phone was off for about an hour straight, think I'm getting better "sleep" periods. Launcher activity is constantly blue.
I use the modified launcher with the extended settings. Only widget on it is fancy widget pro.
Going to see how well the phone fairs for the rest of the day.
EDIT:
Been doing research, apparently telocation causes a lot of battery drain, and alarm manager (although mine is almost always asleep).
I recently uninstalled fancy widget in hopes that launcher won't keep itself awake, and froze the telocation and no freeze or force close on anything.

I had a major battery issue with my last install of CM7 on a new G2X, what fixed it for me was enabling "use wireless networks" in location and security settings. I noticed something was odd when I ran speedtest and every time it would try to connect to servers in NY or NJ(I live in NC).....I'm not exactly sure what was going on, but enabling it fixed my battery life.

Anyone else disappointed with Extreme Power Saving Mode?

Anyone else not getting much "extreme power saving" when EPS is turned on? Honestly, my phone seems to drain at the same rate whether it is on or off.

At least triples my standby battery life over standard power saver mode.

10% overnight sounds like a lot. I would have to think you have an application that is causing the issue.

I get better with the normal than I do the eps. I can get through a day with normal to heavy use. And eps seems to drain just as fast

What battery level to you have it configured to become active? It doesn't run all the time - only when your battery reaches the configured level. It will not improve your day to day batter life - it helps your phone to last longer when the battery gets very low (configurable to either 20%, 10% or 5%) by turning off everything but essential features like calling, etc.

You can also manually turn it on...just fyi.
I'm going to try it out tonight with a full battery and see what I end up with by the morning.

I manually turn it on at night when I go to bed.

On my m8 in power saving mode I tap on the leaf to show the battery usage while in power saving mode and among other things it shows the Kindle app as using battery even though I never use it. My understanding is that it should only be running phone, texts, and the clock I wonder if this is a bug.

Yeah you've definitely have something keeping your phone awake at night. I'll drop 1% over 8 hours at night. With no EPS and leaving 4g on

10% over night with or with out?
You should drain about 2 to 5% over night with no attempt at battery conservation.
Also, the term "overnight" is very relative. I sleep 4 to 6 hours a night. Others 8 to 10...
Its best to describe battery drain in percent per hour %/hr

About 10% every 7-8 hours.

Rogue apps in EPS mode?

I also have strange apps running in Extreme Power Saving mode:
Amazon Kindle
Facebook
Skype
[Amazon] Appstore
What the **** Verizon?
Edit:
Add Amazon Music to that list. Just popped up now.
Edit edit:
I was wrong, it works great! You just need to set it and forget it (like while your sleeping)

Mine says Facebook, Beautiful Widgets, and Google Search have each used 1-2% during EPS mode.

I have found that Google plus, tasker, Kindle, snapdragon battery saver use battery. worst of all extreme power saving mode uses 5-15 percent of the battery usage

How are you able to see what apps are running while in EPS mode?On my wife's M7 I can't even get into the settings menu. Let alone open a custom app.

Tap the leaf next to the clock.

Turn mine on at 10 at nigh and its 100%. Wake up at 5 and its still sitting at 100%. Been great for me

This does nothing for me. But mine is working fine I lose about 0.33%/hr.

I've changed my mind
I turned on extreme power saving mode at midnight with 86% and turned it off at 8 am to find it still at 86%. Only tasks using battery in the morning before I exited EPS were essential apps (dialer, messages, and two others which I forgot).
Needless to say, I'm very happy with its performance. If you just turn it on and leave it alone, it seems to work as it is supposed to.
