This battery life isn't normal right? Bad drain

I cant tell if it's always been like this. Or if this actually isn't normal because I'm always concern with battery life. Im a very heavy user in the sense my phone will be on and im texting, xda, social apps i.e google +, email check every hr, and twitter.
However, i started feeling like my battery has been draining alot faster when the screen is on. I have no problem with the phone sleeping. I was experience this on Calk rom and now acs ics rom. I literally can look at my battery percentage drop 10% in like a half hour. Is this normal if screen is on the whole time? I've used better battery stats and system panel I can't find anything causing the drain. I see the suspend and events but doesn't that effect the phone sleeping?

Are you on the new modem? Looks like you have weak a signal. EG31 might help a little if your not on it already. I used the full EG31 tar right when it dropped and have been getting great battery life (it may be to early but so far so good)

not sure if its going to work but hoping it does thanks for the response still

turn your display down to under 50% you won't see a difference except outside in daylight and kill this app every time you reboot the phone hit Settings>Applications>Running services then hit DRM content > stop > ok
I get over a day on one charge.

Ok ill try the drm content stop..however my display brightness is already down at like 10%.

Also, kill the Social Hub as well, that drains the battery significantly.

You might try one of several roms available in dev. They address most of the aforementioned issues.

The biggest battery drain reason is the location by wireless network option. Make sure its unchecked. Ever since I did that, my battery life has been awesome. I get to keep my brightness high, Bluetooth on, etc...

All the basics (brightness and all that stuff) on top of the stuff you have running. The darn task killer/manager I see in the icon top left of your screenshot is a HOG on resources check the caching... You can literally **** with these phones for half a day to set it up the right way to conserve. I think wireless is hogging too but I am talking primarily about the first part of your rapid loss, the left part of the graph so to speak.

I purchased an extended battery and was still getting crappy battery life. SpareParts always FC'd on me... but last night I found Badass Battery Monitor in the market and in my opinion it's even better than SpareParts!
It helped me find that the Hotmail app was keeping my phone awake for almost an hour every day even though I had it set to download email only once a day. Removed that right away.
Plus it gives a great % readout in notification of the battery level. I think it's a fairly new app, but it really is worth checking out especially if you're having battery drain problems.

Just killing Social Hub has increased my battery life significantly. I'm at 11 hours now on battery, with 62% left. This is from last night when I unplugged the phone at 100%.

I'm on the Sydnicate Rom there isn't even no social hubb app. He has alot of the mods like noCiq and everything. My phone sleeps well its just when I start using it I can see it basically draining like 10% every half hour. I'm a heavy user I know my phone will drain fast while I'm on it I just would expect it to last 8-10 hours on heavy use.
Right NOW:
I'm at 4 hours 12 mins 22 secs at 37% left.
Display Time is 50% 2 hrs 41 mins 51s (Brightness is set all the way down)
Android OS 10%
So I'm assuming in 2 more hours my phone will die. If this is just normal for a heavy user then I guess I have to deal with it?

I was very disappointed with my Epic Touch when I first got it. I was getting a dead battery in about 6 to 8 hours no matter what I did or did not do.
Calibrating the battery seems to have fixed it.
I'm at 73% battery with 8:32 hours up time and I've made about 12 calls ranging from 2 to 10 minutes.
I've also checked voice mails, emails and other stuff.
I just charged the battery til it was full, plugged and repeated until it stayed at 10%, popped into CWM5 and cleared the battery data and then used Battery Calibration from the market (free) and it's like a got a battery upgrade!
As far as wake lock issues, I've not having any of those. I took my charger off the phone around 3:30am this morning (100% charge) and when I left for work at 6:50am, I had 98% battery still.
When I got to work it was down to 96%, I checked my email on the drive there.

I'm trying this out, wish me luck.
There doesn't seem to be any possible way to charge my battery to 100%, unplug it and not have it immediately drop to 99%.

If those screens are both from the same charge, I see nothing wrong with your phone.
you have 17% left, and you have 2.5 hours of screen on time. So you're on target to get just over 3 hours of on screeen time which is completely in the norm for these phones. AND you're over 12 hours. I don't understand what else you could ask for?
People get all caught up on total charge time, but, to be honest, it's completely IRRELEVENT.
If I dont use my phone I'll get easily over 48 hours out of the phone... Screen on time is what matters. And from a full charge, if I were to use my phone for 4 straight hours without stopping, it would be about dead. When the screen is on, you're using the phone, and the display is the biggest battery suck out there. When I do all the tricks to conserve battery, and I set it up right, I get 4 hours screen on time, which is pretty incredible with these phones.
Now, If you WANT to get better then you have right now, a few things are coming into play.
1) Your signal is weak, this will suck power no matter what more then it should, so get better signal if you want some more time out of your phone.
2) If you installed a new rom, and you didn't calibrate your battery properly, you're losing battery life.
to calibrate properly:
a) download battery callibration app from market
b) charge to 100%
c) unplug battery charger and REPLUG IN and wait for 100%
d) repeat step c a couple times
e) while plugged in hit the calibrate battery button in the app
f) unplug phone and use til dead and recharge
This will yeild you the best battery life.
3) De-Theme. Although I use a theme, every theme I've tested, for one reason or another, drains my battery faster then running the stock phone theme.
4) If you haven't done the basic battery saving things, you should do them to help yourself out. Here's a few I use.
a) Turn off background data, you only need it on to use market
b) Turn off, or set sync for all email and social apps at as long intervals as possible
c) dont use any widgets
d) download watchdog lite so you can see when apps are acting up and using extra battery
e) when you're done using your phone, open task manager, kill all apps, and clear memory
f) always leave the brightness off automatic and as low as possible
g) download SETCPU and run your phone at 800mhz, and undervolt as much as possible (50mv most all phone can take)
h) use black or dark wallpapers, on LED screens back means the pixel is off which uses less battery
G will be your biggest battery save. I've also tried using the SUPERFREEZE thing in the dev section and, besides in sleep mode, I saw no adverse effect. If you wanna kill socialhub, fine, but I dont see any noticable difference on my phone with it off.
If you do all these I promise you'll get better battery life.

Wow, I did a proper calibration today and I'm getting great results already. I've calibrated before but I never had cleared stats in CWM or did the unplug then replug charging thing.
Anyways, I after 12 hours I'm still at 35%! The longest I've ever gone before is 12.5 hours. Screen on time = 1 hour 30 min, but some of that was a battery intensive game (puzzle quest 2). Also i'm running calk's rom, so i'm sure that helped.
Thanks kdoggy, i didn't expect to see results this great.
Those are good tips too Jermzz, thanks!

[Q] Battery and screen percentage?

I don't seem to have the standard Android OS killing my battery, but I am still losing battery fast and it seems to be coming from the screen. I have turned down my screen to 10-20% (30 second turn off delay) with no change really.
Screen is normally eating 40-50% of the battery. Android OS only has 14%. Anyone getting similar numbers?

Yes. But in the evening when I plug my phone to the charger before I go to sleep, it still has around 30% battery. I'm quite happy with the battery usage so far.

Good to know, I am a verizon user. I only had the phone since yesterday, so I am hoping this is just a battery burn in thing and my battery life will improve.

Today is my first full day to test my normal battery conditions.. and I am experiencing the same.
45% is currently going to the screen and 20 to the OS.
It still looks like i'll squeek by with about 9 hours of battery life (which is alright).
I refuse to have the screen at anything other than 100% brightness though.

There's your problem.
It's a beautiful screen, especially at full brightness, but I'm fairly certain you can hear the battery sobbing quietly if you listen closely.

Uploaded a screenshot of my battery performance today. It's 9 PM over here, about 2 hours to go before it gets juice again. My screen brightness is set to auto.

[Q] battery drain for LC-ICS

hello guys,
i flashed the radio to 12.62.60.27p_26.13.04.19_M after which i flashed update-LC-ICS-1.0.beta4-DesireHD-signed.zip by wiping completely. During standby, the drain was very less (about 1 mA , occasionally reaching 5 mA.) After 24 hours, the drain increased beyond 10 mA, sometimes even reaching 40mA or more in standby mode. It was only after i rebooted the device, the drain is somewhat acceptable now.
Is this normal or something is wrong? what could be the reason?
in the above cases, the phone was in standby mode, no calls, no data, only 2G. the only difference in the second case was additional applications like facebook, etc but no data, no sync.
btw, i just rebooted my phone and lost battery level from 3.735 to 3.691 , drop of 14% as shown in current widget.
any suggestions ?

I'm running cm7 and for me that's quite normal.
The drain per 5 minutes is between 1mA and 10mA while in 2G standby, screen off, data off.
The drain of course jumps up to 40mA to 200mA if the screen is on and i'm using the phone (wifi on, using google reader etc)
Getting 1mA per 5 minutes all the time sounds a bit unrealistic to me. Maybe in airplane mode and no screen on time.
I guess your problem could be the additional apps. Maybe an app is running wild?
And might i ask what you mean by "battery level"? Are you talking about the mV?

First of all, make sure you're are really wiping everything. Just to be sure, you may follow this steps:
http://forum.xda-developers.com/showthread.php?t=1226016
You can also take a look in your battery stats, the battery usage of mediaserver. In come ICS based ROMs, it drained battery a lot.
I tested LCs 1.0.v4 and also got poor battery performance, may be inherent to this ROM.

hi, standby => night time when no screen is on...
it was about 1 mA most of the times and occasionally reaching 5mA

hi, yes, i have been following the link for wiping since the time i sarted flashing ROMS..
but what you are saying could be right.. the ROM itself could have battery issues...

I'm running LC ICS v1.2. I haven't seen any significant battery drain though I'm using an Inspire 4G. There's also an undervolting app on the second post in his thread. Undervolting has improved the battery performance slightly as well for me...

Battery Meter or Voltage Meter problem?

My G2 gets ghastly battery life. I've tried Juice Defender and I've recalibrated more times than I can remember. Most notifications are turned off and I'm conservative about powering off the various radios when I'm not using them. It wasn't always like that. I felt like I was getting most of a full day on one charge and loving it for many months, but something happened last summer I think. Maybe dust or moisture affected the phone. I've got a total of six batteries and three external battery chargers. No battery whether it's the OEM original, 1500mah spares that were amazing before, or the new 1800mah evo shift 4g batteries I tried out, will last more than about four hours from full charge to the 15% warning sound.
I've tried only charging in the phone. I've tried rotating batteries charged in the external chargers. Like I said, I've tried calibration scenarios of various kinds.
Last night, I took a fully charged 1800mah battery and put it in my phone and then charged the battery in the phone. The orange led never turns green when the phone is off. When the phone is on, I can just barely get the led to turn green at about 91% (starting from what should be a full charge that is reported as 80% by the phone). This takes a good 10 hours of charging. As soon as I woke the phone this morning, the battery meter started dropping while the phone was still plugged in. After unplugging, the meter drops to 80% in a matter of a few minutes.
Like I said, I tried juice defender. It only helps a little but the cost is waiting for the data radio to reconnect every time I wake the phone. I thought BT was the culprit for a while, but now it really doesn't matter if I leave it on or turn it off.
At the other end of the charge, the phone can run for several hours when the battery is supposedly between 1 and 3%. I know we are told to start charging again at 15% but my phone drops to that level in 3-4 hours of regular use. I haven't seen the phone report 100% charge on any battery in six months time, but it runs and runs at 1%. This is what bugs me. Is the phone just mis-reading how many milivolts are coming out of the battery? Why can't I complete the first step of calibration (charge overnight to the 100% mark)? Is there a hardware component that can be causing this or should it be entirely fixable in software?
Thanks for any ideas or tips

I changed radios and did RIL matching last fall based on other's comments about better battery life, 4G and GPS. While I've had faster GPS locks and maybe better 4G performance, my battery life did not improve. It may have even gotten worse.
Today I'm trying out some different CPU governor settings. The CM 7.2 RC1 default is 'interactive' and I wouldn't normally touch those settings. I think the powersave governor helped a lot, but the phone became almost unresponsive. Trying 'conservative' now. I should have read This long ago, but just got around to it today. I might invest in the SetCPU app as well.

OK, I can count on a good six hours of normal use if setCPU is holding down the max cpu frequency at night or when the screen is off. I'm still tweaking. Today, the phone crashed while playing music over A2DP and tracking a run with runkeeper. I think it needs to tick faster than 368Mhz when the screen is off.

Are you seeing improvement? I changed radios and like you havent seen much improvement. But I am a little better off than you are. My battery drain is terrible (1-3%per minute) only when connected to the internet (4g or wifi) or using navigation. If the screen is off, or if Im using non-internet apps I seem to get regular battery use. Good luck with your cpu settings.. I have ordered a new battery, but I doubt it will solve my issue. I may try tweaking my settings too soon, but Id better research more.

Just wondering do you have SuperCharger V6 installed? On my Desire Z I had some serious battery problems just as you mentioned. After I would flash my ROM (wiping the caches + reinstalling) my battery life would return to normal. But whenever I would flash SuperCharger v6 my battery life would spiral out of control. My suggestion for a ROM that handles battery life fairly well is Andromadus Audacity B2, just make sure you download and flash GAPPs (google apps). For example running that rom I have been getting very good battery life, approx. 16-20 hours of battery life with moderate use) with default CPU settings and data always turned on. I'm sure if you use Juice Defender to control your data you'll get above average battery life.
Note: Andromadus is an ICS (android 4.0) ROM

Thanks (and thanked) Ive been waiting till ICS roms are bug free and having working cameras, but I think I may just jump on it now. My battery issues are untenable at the moment on a CM7 based rom. Thanks for the advice.

I was seeing some improvement due to SetCPU profiles. However, now if I have GPS and Bluetooth on so that I can listen to music and track my run in runkeeper, the phone seems to 'crash' after about 35 minutes or so. The battery meter shows that the battery takes a nose dive and I think the phone shuts down at 1%. If I restart the phone, it might say I have 30 or 40% charge left but then it drops rapidly again. It seems like it hates the warmth of my pocket. If I let the phone out in the cool air like on my desk, I can reboot at get back to 60 or 70% even though it was just saying 3%. I'm not running SuperCharger.
I'm trying to find cheap G2s for parts on ebay now. Maybe I can at least test out my six batteries in a different phone to see if any of them are shot. They all seem to have the same problems in my phone.

This will be my final update. I bought a used G2 off ebay. The same batteries I used before now show as fully charged when I expect them to be fully charged. I will be getting a feel for general battery life over the next few days, but I expect battery life to be roughly the same. I just won't have to guess at what the current battery level really is.
I'm seeing now that the new phone will show a 60% charge when the old phone shows 15% for the same battery at about the same time.
The new phone shows 100% when topped off but if I put the topped off battery in my old phone, I see 75-80% charge.
I may try sending the old phone to HTC depending on what they offer for repair services.

I think what's happened to your old phone (and mine!) is that the onboard voltmeter chip is reading low. I've compared the on-board mV reading to a multimeter-measured battery voltage and what the phone reads as 3.9V the multimeter gets 4.2V (a fully charged Li-Ion battery).
Who knows what's behind it, but it seems like a hardware problem to me.

Wakelocks: VBUS_PRESENT & WLAN _RX_WAKE

I'm running CM10 10.0 Stable and the latest Lightening ZAP Kernel.
I've always had problems with battery life that are somewhat random. Sometimes my phone will last over 24 hours with the same usage as when my phone decides to die in 8 hours. This is very concerning because I know a phone should not be this random with the same apps and usage charge after charge.
I've relentlessly searched for the wakelocks that keep this crazy phone awake using BetterBatteryStats, CPU Spy, Battery Monitor Widget and GSam Battery Monitor. My average charge time on a rooted stock 4.0.4 was about 20 hours. My average time on CM10 stable is 8 hours. I now carry around an external USB battery all the time because of this with a wall charger and multiple micro USB cables in my arsenal.
Now I'm playing with undervolting but I know that's not getting to the source.
My phone does seem to go into deep sleep when unplugged but only 50% of the time. I've read that VBUS_PRESENT is when charging with a non friendly charger. Well I've been using a stock Samsung charger that came with my phone and it still shows up. WLAN_RX_WAKE I'm totally not sure of...it uses a huge amount of time keeping the phone awake why?? I'm not sure. It didn't used to do this and I leave WiFi, Data, and Syncing on. I have the same outcome whether Google Now is on or off as well.
Any help would be really really appreciated. I think I have battled battery run time since I started using Android. I wish it wasn't like that because I love the openness of the operating system compared to iOS which I have used in the original iPhone and every generation up to the iPhone 4. If you guys require screenshots I'd be more than happy to give them. There are so many smart minds here that know far more than me and I know it!!

I'm having the same issue running Gangnam Style CM10 on my Evo 3D. I'm seeing huge wlan_rx_wake wakelock that I haven't seen on any other ROM (same networks).
Apparently, it's multicast network traffic that the phone should ignore, but instead wakes up and replies.
Sucks.

Hmmm strange. I reformatted my phone and wiped everything clean...and reinstalled CM10 stable with the newest lighting zap kernel. But now the phone app is taking a massive amount of power from wakelocks and CPU. My phone is left with a higher than average CPU idle running at 1566MHz for 40% of the time before my battery dies at 10%/hour. Something is really up and I can't figure it out. I know that when my phone was operating at 4+ hours per charge the temp would be under 30C. Now running at idle it's 33C. I normally never feel the back of the phone heat up near the camera LED but now it sometimes feels warm or hot when it's deciding to try to deplete power within a few hours. This is a strange thing....I don't hear of people with CM10 having this problem...or does everyone think having an 8-10 hour burn time is normal?

Just switched to Slim Bean ROM (JB) and still have wlan_rx_wake jamming me up on wifi networks.

u guys need to change the settings under the advanced menu to tell your phone when to enable/disable WiFi sleeping, the delay amount, that's what the wlan_RX wakelock is
as the op stated,vbus is indeed when using a charger other than the stock Samsung one that came with your phone

What should the delay amount be? I used to have it set to 5 minutes under "only when plugged in". I use my OEM Samsung charger and nothing else but I still get vbus.
I just did a test and turned all data and wifi off. Battery drain has been completely normal at less than 1%/hour. This is great so now I need to find my internet culprit. I get the same type of nasty battery drain with Wifi on, Data on, Wifi & Data on.

I'd rather have the wifi never sleep. Why use a low speed, higher power radio (3g) when you have access to a wifi network.
Wlan_rx_wake never kept the phone awake on gingerbread ROMs.
