[SOLVED][Q] Battery issues?

Wondering if anyone else has had any battery issues? I went to sleep last night with about 85% or more battery, and 5.5 hours later my phone was dead....when i plugged it in for like 5 minutes to call my work and tell them i was going to be late...when i got to work my phone said 45% phone idle and 45% cell standby for battery use

none here - took phone off charger about midnight, this morning after alarm rang for the full 10 minutes, it still showed 100%
i've been watching it and am really impressed with battery life - is it possible you've got a program running in the background? - i had Startup Auditor to stop apps in the background but had that from before, on my Vibrant
on the vibrant,running a predominantly black wallpaper, screen brightness at 13%, putting phone in "airplane mode" when i sleep, keeping GPS off, data sync off etc, it'd be down to 17-22% at end of day before going back on charger
this G2, running live wallpaper (thunderstorm), no efficiency moves (ie GPS off, etc), screen brightness at 50%, phone still had 34% last night before going back on the charger - and the battery has not "conditioned" - i noticed on the past 2 phones batteries life got better after the first few weeks of use.

Nothing different than my nexus...and i was thinking maybe it was a game but that should have been killed automatically and i dont think it would say phone standby and cell idle if it was an app would it?

tonite you might try putting the phone in airplane mode when you go to bed, and turn off GPS
see what happens to battery drain overnite - if it diminishes then i'd look at what apps you've installed. there was an article on engadget not too long ago that some researchers had analyzed the 358 most popular apps, and found 30 were reporting data to their "mothership" that had not declared it or asked for permission to report data.
hope that helps

well another weird thing is, that when i bought the phone and brought it home, usually it comes with half battery and thats what it showed but i had to charge it quick with no apps really installed on it yet...Im charging now and will test to see what happens with battery...i just removed off alot of my apps.... to see whats up

I'm getting about 10 hours with regular usage though I wish I knew why Photobucket keeps starting everytime i kill it.

I hope you guys charged the phone fully before you used it first. That can play a big role in battery life.
I got my phone yesterday and haven't done any calibrations yet. I've been playing with it like you normally would if you buy a new smartphone. I took it off the charger around 9pm last night and at 7:32am right now I have about 60% left. So roughly 10.5 hours later and I've only lost about 40%. I'm very impressed by that. My vibrant would have been dead by now, it rarely lasts through the night if its not on the charger.

What's your time with out signal, sounds like the 50% bug to me, google the airplane mode fix, if not you might want to look into a new radio, and you should allways recal your battery after you flash

wp7 unknown battery drain

For the past 2 nights i have been experiencing this
had 50% power left the night before...
after 6 hours sleep
phone is out of battery @@
Now that aint right, im guessing something is running under locked screen and iono what!!! but i always jump out of any program when im about to sleep too, so it cant be because of that
In the past, i could have standby time for a long period especially after one night. But the past two days when i woke up, it always ran out of battery!! Also when i charged my phone to full life, i sometimes come back after a hour or two to find it dead!!!
This has never happened before and im wondering what could be the cause of it.
In the past i could leave my wifi, bluetooth, location on and it would still last overnight and i wasnt running any program
It cant be because of alphajax right? I mean i did install that two nights ago :\

That is really weird, which phone do you have? I have the hd7 and get 2 days between charges most of the time. Have you tried uninstalling alphajax to see if that helps?

I use a HTC mozart 7
Im gonna try uninstalling a few apps to see if that helps or switch to my secondary battery pack

just to let you know i watch videos before i go to sleep and because its get so hot it drains battery faster, even though i had 50% after I finished watching it went all out in about 8 hours of sleep.

That sounds highly likely, i was playing a game before that, then left it alone for 1 hour, check still had 50% battery, and then went to sleep
woke up with a dead phone

I will confirm that when I have overworked my focus, ie several hours of video and games, the battery can get very hot and if I wait until I get the low power warning, plugging it into my laptop USB can't keep up with the drain.

ok this is ridiculous
in 3 hours i lost 30% power on standby
ITS ON BLOODY STANDBY!!! lol i cant figure out whats causing it. I didnt use the phone for anything at all then put it to charge till 100%. Started counting down time...

If I were you and you dont mind loodsing games aves etc, Id try a hard reset and if that doesnt solve the problem go to LG and ask them to fix it if there may be a fault.
Sorry I cant help further and Goodluck!

I've had this issue as well. This has been going on for months for me. Before NoDo and the pre-update.

Perhaps the battery isn't calibrated properly. Mine shoots down to 50% over the day but sometimes an hour or so after I hit fifty the battery goes critical then dies.

Battery Drain
I have the Samsung Focus. Pre NoDo I could get maybe 18 hrs in standby, and charging from USB on my computer was not happening. I had to plug it into the wall. If I actually used my phone for maps, calls, web or whatever I would get about 10 hr's depending how "how much I used it". This was with EVERYTHING turned off. Bluetooth, location services, feedback, anything and everthing I could disable. After NoDo, I get about 2 days, and now it will charge from my computers USB. Go figure.
All I can guess is there was some sort of corruption in the ROM.
Just a side note, does anybody know what "NoDo" stands for???
Answer: No Donuts

Before the February and March updates, I woke up one day to see my battery had drained from 100% to 0% in about 6 hours of sleep. After recovering from an angry awakening next morning, I paid a lot of attention to how the battery was draining. So I charged up to 100%, went to work on the tube as I always do, and noticed how after about 45 minutes, the battery was down to 50%. That was just some music playback and checking a few mobile websites.
In the end I remembered the day before I had installed two applications, one of them being Lyrics and the other one being a BPM (beats per minute) detector for getting the tempo of a music track. I decided to remove that application and, voilá, the battery drain stopped. I would have uninstalled the Lyrics app but this was already taking me to a decent power usage state, so I stopped there.
If I were you I would check recently installed apps to make sure you don't have a power drainer that's magically working in the background when you put the phone to sleep.

Did you disable feedback in settings. That extended my battery life considerably

I know what your going through, but i found the solution.
Your mobile data is constantly running to check for updates on the game and push notifications. Disable data connection whenever your not using it, and i swear you will see a massive improvement. I have a htc trophy and its notorious for its bad battery. I used to only get 4-6 hours out of it, and now i get 12-14, with WiFi.

That reminded me.... alphajax uses push (although i had disabled it) to notify the user if the other player had made a move...
It all seems LOGICAL that alphajax is the culprit here....
but i also have lyrics, how does that app affect the battery???

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!

100% to nearly dead in 5.5 hours with no usage at all

So my battery life so far has been hugely inconsistent. The first day it was draining so fast (60% in an hour) that I contemplated turning around and taking it right back to the Verizon store.
I decided to give it a better chance than that and gave it a full conditioning cycle and all seemed well - I got 16 hours with moderate usage including an hour and a half where my screen was constantly on! I was very pleased. Extremely pleased.
So I charge my phone back up to 100% before I go to sleep then take it off the charger once it does. I drift off into dreamland, dead to the world, and five hours later I decided to check my phone for calls, texts and email.
Before I could even pull my notification bar down I saw something horrific - an extremely low battery capacity, nearly red. Checked battery usage and it said it went from 100% to 13% in about 5.5 hours.
Android OS - 64%
Phone Idle - 10%
This is the big indicator. Under Android OS, my phone (not the display) was kept awake for an hour and a half overnight. I'm really not sure what's going on here and what's causing this to happen. I haven't downloaded much - 1 game, Skype, Google Reader, Facebook, Tweetcaster, Evernote and Foursquare - and none of them showed any signs of being the culprit.
As you can tell, this is very worrisome. If I can't get more than 5.5 hours on a full charge what use is this phone to me? Does anyone know what could be going on or has anyone else run into this issue?

Thank you! I will direct my attention over there. Mods please close this thread.

[Q] Do I have a faulty device.?

So I had several calls yesterday for over 30 mins each..
Each time i would hear echoy sound of my voice, and i also feel like i could hear the voice coming out of the phone lol, even though the phone isnt on speaker.
I also my have a bad battery it'll go pretty low i guess. Yesterday was my first full day using it, went to work at 70% since i forgot to charge it, at noon unplugged it's at 100% came home around 9 and got 10% left. , so i got 9 hours in total, from calls. light browsing, light twitter, facebook use.. I havent even setup my work email, and i constantly get over 100+ emails a day on my account. So i know battery will go significantly
Should I wipe everything clean and see if it works.. I have 14 days to return for a new one.
also today left my house at 7:30.. it 9:50 now and already at 75%...

I think someone else on here had similar issue with having an echo when speaking into the phone. If im not mistaken they exchanged it and the new one did not have the problem. Maybe you should take it in for an exchange.
As far as battery life, well it seems to be varying from user to user. I am getting pretty good battery life, anywhere from 12-15 hours on a charge with medium use. On light use I get well over 15 hours. There are some that seem to be having poor battery life. Have you checked your battery stats? Whats your android OS % at? And what is your screen on time? Have you turned on ECO mode?

Assuming you dont have a lemon, it all depends on how you use your phone.
Do you have lots of apps with push notifications?
Or do you have lots of apps that check for new notifications every 10 minutes?
Screen brightness? Screen-on time?
What radios do you have on?
...the list goes on
On a typical day, I can get about 12 hours with moderate use (3 hrs screen on time). Close to 24 hours with light use. Mine idles pretty well (approx 1% or less battery loss per hour).
FWIW - my 'Android OS' is usually at around 50% and screen is at about 25%

Doesn't seem like a lemon to me. Falls somewhat in line with my battery experience.
You can check screen on time by going to the power saver in settings, scroll down to battery use and hit that. Then hit 'screen'

Yeah - I never turned those on or used any kind of juice defender either (thought I am on Wifi alot). I think you're fine.
Try this - fully charge your phone before you go to bed. Leave it off the charger over night. See how much your battery drops. Even with a few google accounts on push, facebook messenger push, instagram push, LG social+ and a couple of news readers that auto-update every few hours, I've seen my battery drop at most 5% over 7 hours.
