[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

How much battery do you lose over night?

Stock Nexus 4.0.2, everything off,...data, wifi, sync,...between 11:30 last night and 7am this morning went from topped off 100% to 92%. Seems like a lot to me for having everything off. Whats anyone else experience?

In the past, I have aimed for 1% per hour idle. Currently, w/ everything on, connected to wifi, and on cm9/Franco, I get 2% per hour.
Try airplane mode to get it lower.

With wifi, sync, and everything on, I go from 100% to about 92% in about 8 hours overnight. Not bad if you ask me.

Stock here too. I charge after I get up, so I leave my phone idle while I sleep. For the first week I turned off wifi before going to bed. I would lose around 12-14% each night. Last night I kept wifi connected and only lost 5%. Seems wifi uses much less energy than the 4g radio.
Going to keep wifi on this week and keep an eye on results.

4.0.2 stock with everything good on (wifi, syncs, gps, etc). i went from 11% to 8% in a 11 hour sleep (don't judge me!).

About 3% in 8 hours. GSM 4.0.1 stock, WiFi on overnight.

screen off airplane mode = 5%
screen off 'mobile data disabled' = 8 - 10%
screen off (4g on) = 40%
i don't do wifi.

Running Revolution HD with Wifi connected I lose ~1% over a 7 hour night. That's with stock kernel with a profile set to the lowest clock with screen off. Syncing was enabled.

I charge when I'm sleeping. Isn't that normal.

that's because you're using Juice Defender. uninstall it and just disable 'mobile data' when you go to bed.

Picked up the GNex on the 23'd and the OEM extended battery on the 26th. I charged up the phone with the extended battery then ran it for a bit over 24 hours and had 47% remaining after 24 hours.
I unplugged from the charger at about 11PM and the next morning, after about 8.5 hours, the battery was at 87% -- when I plugged it back in a bit after 11PM I was at 47%. I did not use the phone a great deal that day but I did use it. I had LTE, WiFi and GPS on and was within WiFi range about 80% of the time.
I'll see over the next couple weeks when I go back to work how it fares...

I use juice defender as well and I lose about 8-9% over 8 hours of sleep running stock 4.02 rom. And I dont run a night mode when Im doing my tests so wifi enables every 30 min to sync.
Do you customize your JD settings because 61% is ridiculous, I wouldnt be surprised if it was some other rogue app, you can use watchdog to monitor that.
Running Gummynex 0.3.0 with Imoseyon's lean experimental kernel v3 last night I lost 2% over 6 hours w/ JD.

Running AOKP with the stock kernel and I lose 4-5% overnight per 7-8 hour sleep.
Not bad at all.

I use to lose 2% over 8hrs of sleep. wifi/data everything on as normal. Was on stock 4.0.1 kk1 unrooted. I'll test tonight with stock 4.0.2 rooted kk7

Galaxy Note II GT-N7100 battery problem

Hi guys, I just got my galaxy note II for like 2 weeks ago. And i've noticed a problem about my phone.
My galaxy note II will drain the battery for like more than 20% ( 20%-25% ) while its in idle. Which means after i fully charged my phone, i unplugged the charger and i used it for awhile more like it was left 92% before i slept. Then the next day when i woke up i noticed that my phone's battery drained about 20++%, it became 79% (i slept for 8-9 hours). I didnt leave it with wifi on. I just left it with 3G & power saving on!!!! This is a serious problem, i mean how is it possible to drain for 20% just for around 9 hours of sleep.
And one more question, how long does your galaxy note II battery last after a full charge with you playing checking the phone for message once for almost every 20 mins?
Normally i woke up around 9am for work and by the time i reach home at night around 12am. It still has around 30% of battery. But today, this strange thing happened. I unplugged my phone around 9.30 am. Starting of the day was okay, it was normal. But right after it was reduced to 60%, the battery started to drain faster. By 8.30am it was already left 25%.
:crying:
GUYS HELP PLEASE!!! AS IM NEW HERE. REALLY REALLY NEED A SUGGESTION ABOUT WHAT TO DO TO MY PHONE.

Yes the battery does drain even as you sleep. Keeping 3G on actually drains more than Wifi. So if you really want to preserve your battery overnight, turn off your mobile data totally. It is somewhat an annoyance that you can't choose between 2G/3G like you do with iPhone. If you still want that connectivity, leave wifi on instead of mobile data.Give it a try for one night and see how it goes.
Are you using any power saving apps?

I just tried again last night and it drains from 100% to 81% from 8 hours of sleep? Is it really normal?
I am using this app callee "cpu spy". Over 8 hours of state time. Only 5 and a half hour my phone is actually in deep sleep. 200mhz for almost nearly 2 hours. And the rest go to 1000mhz and 1400mhz. Do you understand what it means? I dont. Can you please explain?
And im not using any battery saving app. Any suggestions?

Solution for battery problems

after talking to lg and rogers i found a way to fix my battery bug or what ever it was........
Issue: weak battery-very bad battery life-needed to charge twice a day on normal usage. Lg and rogers both said its a hardware issue and need to be replaced......(IT WASNT)
Solution few easy steps should fix it:
1. Let your battery die to 0%. It drives down by 2%. Turn it on, it will let you turn it back on and shots automaticly back down. do it a few times till it shows0%!!
2. Plug it into your charger and let it charge to 100%.
right now its 2 pm i started using the phone at 9 am haevy!! besides that is my s3 that i used half as much today. Battery life on the optimus G is 60% and on the S3 55%. Battery life of the LG seem to went to normal. they claim its 40% better then on the s3. im trying tomorow on eco mode see if there is a difference.
PS: sorry for my english im italian live in canada and grew up in germany haha

I'm not so sure this is a good thing to do. I've read that you should never allow a Li-Po battery to drain completely because it physically damages it.
Then again, it's hard to find credible information on the subject.
Edit: Wikipedia cites the following article which states that overdischarging will damage the battery: http://www.powerstream.com/li.htm

Damage is when you leave battery discharged for some time, short period = almost 0. Of course there is little damage by doing this but no more than frying your phone at 100% Sorry for my english..

Fixed mine tho my battery life is crazy long now

It calls the placebo effect.
Li-polymer batteries calibrated on factory and they absolutely dont like deep discharging.
By the way LG promised 800 cycles of charging before the battery will start dying. I think in case of full discharge, the amount of cycles will be greatly reduced.

I have provisioned my battery which means going from full charge to 0 three to 4 times when I first got it and I always get a full day with medium use now.
Sent from my LG-E973 using xda app-developers app

I'm wondering, if this provisioning is so helpful for a battery, why wouldn't they do it at the factory?

After reading your guys' posts I decided to do a bit of a test.. I ran my phone all the way down from 100 to 0.. phone turned off.
Then, I turned my phone on about 5 times which then would immediately shut off onve booted to the os.
Then, I turned the phone on and placed it in the recovery mode.. doing this ensured that the screen stayed on until the phone was indeed drained entirely.
Then I charged it up till 100% before I went to bed, turned airplane mode on, closed the screen and went to bed.
Wake up this morning and looked to see how much battery drain occurred during sleep.
After about 5 minutes of using my phone it dropped down to 97%.. only lost 3% overnight. I was very pleased to see this as it confirms in my case that the phone is able to go into deep sleep.
I've also noticed that my battery seems to be draining slower than before.. before I could surf the web for ten minutes over wifi and lose a full 10% of battery.. so far today I've been on the web, downloading email, messing with some apps for around an hour or so and I'm currently at 86%.. definite improvement I believe.
And FYI this is with eco mode off, screen at 50% brightness, no gps and sync on sparingly. This is also on the latest update (my phone is on bell)

I'd be really tempted to try this, but I've heard so much from so many credible sources that total drain on Li-ion is bad news. Conflicted

It's bad to constantly cycle it full to empty. A full cycle once in a while is fine and on some devices it's necessary to calibrate the battery. Additionally, it's not good to store the battery empty. There's no harm in letting it drain all the way occasionally although killing it then further killing it in recovery is probably overkill.
Sent from my LG-E973 using xda app-developers app

Indeed, I only did it in the hopes that it would help to recalibrate the battery.. I recently was forced to run a flash back to the original firmware using the kbz method.. I was able to bring back to stock but noticed afterward that my battery life did not seem anywhere near as good as it was prior.
It could be that the kbz I flashed to was the newest updated version and it just isn't as good with the battery life but I felt it was worth trying draining all the way to see if it would help.. it does seem to have helped a bit though my battery still shows that android system keeps awake for 4+hours which is odd..
Anyway, once in a while I don't see it being a big deal.

If anyone is going to attempt the things mentioned here, why not do us all a favor and post some actual numbers from Better Battery Stats (a before and after) for some real analysis.
I'm not implying that anyone is lying, but it is just too easy to perceive an improvement when that is what one is expecting.
The plural of anecdote is not data.

[Q] Battery Drain Over Night

When I had my Note 1, for some reason over night it would drain like 50% of the battery, no idea why so I sold it. When I has my iPhone the most it ever drained over night was about 5%, 4 and 5. Last night my Note 2 drained about 12%, the only App open was the Alarm.
I know 12% isn't anything major, but with the problems I had with the Note 1 I just don't want to wake up have been fully charged the night before and then have to charge in order to even use it the next day. I need an alarm set or I won't wake up to go to work.
What is the best way to keep battery life over night but still have an alarm set?

Install betterbatterystats from playstore to keep a check on Battery hogging useless apps.
YOu dont need to keep the Alarm open in the background exclusively. When you set an alarm,it would be there untill you disable it manually.
12% overnight is a bit more than normal. For a 6-7 hours, battery drain should not be more than 5-6% when the screen is off and phone goes into Deep Sleep mode.

Why not just charge it over night so that you always wake up with 100% :S

Cause the charge cable is short and doesn't reach to a sensible spot for me to be able to quickly turn the alarm off before it wakes the rest of the house up!
I'll do a few more test runs before I install any battery apps, from what I have seen so far most apps actually mess up the battery for me. That Battery Widget Reborn on my Nexus 7 takes the charge time from about 2-3 hours to 7-8. And one's I've used in the past actually drain it quicker.

Betterbatterystats is not an "battery" app. Is an app the monitors your phone and reports misbehaving apps or partial and kernel wakelocks.
It has nothing to do with increasing battery charge time.

May have to give it a go if the problem persists, but for 10% battery it's not major. But thanks for clearing that up!

The only thing that you need to do is turn off data connections and wifi. This way I lose 1-2% battery life over night.

Well Android's ecosystem is made in this way. Literally you can't do anything. If an app or a couple of apps think that they need to run at a certain time, then they WILL run, it's as simple as that. No app is there to stop it, but yes some apps are there to make it worse, so stay away from them. One night you will notice 5% drain, the other night 10%, with same exact settings.
Still try to turn off Data/3G at night, if you don't need it. And get used with it
