Battery thread

Wow, this nexus is thirsty! Charged it twice today already and now charging again! I was expecting it to be bad but not this bad!
This I'm my first android phone so any tips to increase battery life will be greatly appreciated. I have turned off nfc and also all 3 location/GPS options but didn't change much. I also downloaded a application to kill running tasks etc.
Thanks in advance.

Hey.
Turn off background data and automatic account sync. Should save alot on power!
Personally, i wouldnt use a task killer. As ICS already has a task manager integrated.
Hope this works.

Juice Defender is your friend. The ultimate version is worth the money

This post slightly worries me. On the Evo, I spent half the freaking memory trying to keep my battery alive for more than 5 hours.
Future updates on battery life are truly appreciated.

Your task killer might be the problem. Also, make wallpaper black amd anything else you can as this is oled tech.
I invented cyberspace. You're trespassing.

Maybe you have wifi, bluetooth or your phone is doing lots of downloads. Try to put your phone into 2g + Data= off if you don't use the data, for me it helps a lot

Background data sync ate up a lot of my battery. Apps such as Facebook, twitter, weather apps, weather widgets all typically perform some sort of background sync. You have to go in and disable them.
Avoid task killers, android is usually good enough at managing mutitask.

1. turn dual mode GSM/WCDMA off
2. choose one mode only, preferable is GSM
3. uninstall task killer.

Root the device, download setCPU and create a profile to set the CPU as low as it can go when the screens off

I hate when people say this kind of stuff. Having WiFi and Bluetooth on, but not utilizing them, does virtually nothing to your battery. Anytime I'm in my car (80 minutes a day, just for the drive to and from work) my phone is connected via bluetooth *AND* WiFi to my car. At work, I have it connected to WiFi at least 80% of the day (sometimes I use 3G for various reasons). It barely makes a dent in my battery.
If you have WiFi and Bluetooth on but you're not actively using it (and you have it set to not be scanning for new signals all the time), it won't do much to your battery life.

Lower screen brightness levels to a comfortable level.

You're right with your points but probably the op doesn't know how to deactivate wifi scanning he already mentioned that it is his first Android phone.
@op could you probably use your phone like you did before and don't mess around to "improve" the battery life. After a couple of hours take some detailed screenshots of the battery settings menu. It's very important that we can see how long your phone was awake, how long the screen was on, wifi etc on or not. Give us as much information possible. Otherwise we're not able to help you. In addition keep in mind that your battery needs some time until it reaches it's full potential.

Firstly - Ignore all the comments suggesting to switch something on or off and to use other Apps.
I got my GN 20 mins after the London Launch and im easily getting 27 hours on a full charge with lots of background data on.
Let your battery fully drain a couple of times then fully charge it.
Also be sure to check in your battery settings (Settings > Battery) to make sure there isnt a particular app thats killing your battery.
Also see if there are lots of open apps in the recent App button, close any that arnt needed.

Only fully drain and charge your battery for calibration purposes. It is not a Nickel-cadmium battery and this is not good for it. I have found that charging it at a lower voltage through USB (my PC or Xbox, not USB connected to wall outlet) will give me more juice throughout the day. I haven't done any tests and cannot confirm these results, it is just a believe between my friends.

1) get rid of that damn task killer.
2) turn off wifi and bluetooth if you're not using them.
3) GPS isn't a big deal, but turn it off if you know never going to use it (you can leave on assisted cell tower GPS).
4) turn your brightness down or use auto-brightness.
Just use it for a few days. because its your first phone you're probably using it a TON. Life will get better once the "newness" wears off and you get into a normal usage pattern.
Do this, and if your battery is still crappy in a few days then look into other options. Don't go installing weird battery saving apps or anything right off the bat.

Well, sort of. The first few charges should be full charges (because the initial calibration of the battery sensor takes a few good full charges). Basically, all the way to dead and back up again.
Then do that once per month. Aside from that one time per month, just keep it charged any time you can. Plug it in at every opportunity. When I'm at work at least 80% of the time I have my phone in a dock on my desk. My battery life was 99% on my Atrix 4G when I gave it to my dad 3 weeks ago. My battery life on my iPhone 4 was 97% when I sold it after buying the Atrix.
Heck, my previous Macbook Pro was 2 years old and the battery life was listed as 94%. Lithium Ion batteries are fantastic, if you handle them correctly.

As others have said there's no need for the Task Killer. Just adjust settings to make sure certain apps aren't pulling data too frequently.
My battery stats show 19 hours use with 28% left, with wifi active but set to sleep never when plugged in', phone was used a fair bit during the day also. Its never going to be amazing but IMO its more than acceptable
Sent from my Galaxy Nexus using xda premium

just hope it lasts 24 hours with light use

My top two tips is, go into fb app and enter settings, set it to NEVER update automatically, any time you ooen the app it will still update and it takes a sec or two.
Nr2 is dont use task killers, it will only work your device harder, keep killing tasks that then has to restart from scratch over and over and over again.
Edit, also, if using like weatherbug widget, set that to only update every 4 hours or so, weather dont change thaat much in a day.

The Battery Really Is Amazing!

Hi guys,
Go this One X about 2 weeks ago tomorrow, so I'm guessing the battery has now reached its maximum capacity. Yesterday I was using my phone loads, I had nothing to do and so I kept messing about on it and I got these AMAZING statistics. I'm on 1.29, and for a heavy day of usage these statistics are excellent!
Anyone else seeing anything like this

The battery consumption in standby is almost negligible. 3% for all the night. Having the same kind of statistics since last 38days. But the consumption when the screen is on, isn't so great. But for me it can easily sustain for a day, only thing I have to keep my hands off my mobile.

I have often noted not a single % loss overnight! I couldn't believe it when I went to bed (it was 91%) and woke up 7 hours later and it was still at 91%. I confirmed this behaviour over about 3 or 4 nights - same. Very impressed. Overall I must say that I am actually pretty impressed considering what this phone is packing inside. Over the weekend when I'm not using my phone as much as during the week (family duties call ;-) I can go about 2 days without a charge which is outstanding. The One X is by far the best handset I have ever owned. I love it.

I agree with this statement. I can't go that long without a charge, but there again I am always using my phone so you know. The GSIII has nothing on this, it really doesn't.

Totally recommend a factory reset, by the sounds of things your battery needs calibrating or something firmware wise is wrong.

Done it many a time mate (I install new ROMs every week or so)
As for calibrating my battery I have done it once but I will be trying it again soon

There's a market application that can do it, but it will install those annoying adds that put the little green '+' in your notification bar, however uninstalling the application will remove these.. so you could do a calibration and run

I'm also really impressed with the battery life
It's so much better than my old iPhone 4S
Here's a screenshot of a few days usage (using the phone whenever I needed, no just leaving it idle for days.... )

I wish i could be that enthusiast about the battery life. I ran the HTC Battery Test and it went from 100% to 89%, which is supposed to be really good (or at least shows that there is nothing wrong with the battery). However, when the screen is on, the battery level decreases pretty quickly. I've seen people here who use the screen for 4 hours and still have 50% battery but it's clearly not my case.
I've had the phone for like 10 days, so maybe it will get better. Let's hope so

It is because you have hardly used the phone as indicated by the fact that the screen is only at 28%. The standby life is good, however as soon as you start using the phone battery goes down fast. Also it does not update battery properly while in standby, as soon as you start using it the battery will drop by 5-6% in one go.

Stock v20c (AT&T) battery life

I have always felt that stock has offered the best battery life in both standby and active. I re installed 100% stock rooted with this method (thanks reddevil) http://forum.xda-developers.com/showthread.php?t=2052321. I also installed the LG Optimus fast dormancy tool that I found on another XDA forum and can be downloaded here: https://drive.google.com/fe/m?gsessionid=WZD8FPkXXWpJWcFV3xyoCg# and this is what I acheived:

Stock... Sweet huh? I found that by disabling fast dormancy it makes a huge difference in standby battery drain. Unfortunately it only works on stock (all versions). Without it the internal timer is always waking up the phone to check on network status which really isn't needed. I also have gotten away from using the hi-cap so on could use cases

I actually didn't look maybe a little less than an hour. Did surf for a while and paid some bills a few phone calls and the flat spot on the graph was over night so it would say very light use. I usually use my phone a lot more but forgot my charger at work so I was deliberately used it conservatively. The dashes below the graph are the wake times.

I'm getting pretty much the same with data turned off (sync for 5 mins only every hour) and not using the phone (2-3 % discharge per hour).
But the thing is, when i actually use the phone (screen, web browsing) it discharges like 30-40% per hour (non-stop use). I feel this is wrong, is it?
Fast dormancy fix applied.

We have almost no adjustments that can be made with screen on. Maybe some tweaking here or there. My biggest concern was power drain with screen off. I set out on this quest when I first got the phone in May and it had Gingerbread and I was draining like 5% / hr with the screen off. CM9 was better but horrible with screen on. I found stock to be the best balance but until I found this FD app it was still draining 1-2% per hour now it's like every 2 - 3 hrs. To get back to your question.... Is it normal? Well yes and maybe it really depends on what you are doing.. Surfing the Web... Not so much. Talking on the phone.... Playing games, etc heck yes that is normal. Try adjusting screen brightness and also an app like juice defender that can dynamically adjust cpu & screen.

You are missing the whole point of my posting. I was promoting the capability to improve the Nitro's battery life while in standby. We Nitro users can get all the battery life we can get and it is up to you if you want to reduce stand by battery usage by over 50% by using this FD toggle app. I would suggest trying this app for 2 days and use your phone like you normally do then two days without it and see for yourself if you have better battery life. Just a heads up with the app DISABLE must be selected for it to work. Pay special attention to Android System power usage vs Cell Standby power usage. If Android System is more than Cell Standby you will have greater power usage with screen off.
Sent from my LG-P930 using xda app-developers app

my point was i get better battery life than that with no battery saver and no fast dormant tool, i use liquid nitro v6 and callibrate my battery every other week, right now this is what my usage reads.
35% battery remaining.
Usage
36% screen
18% standby
13% android os
8% phone idle
7% android system
5% media server
5% wifi
4% voice calls
3% bluetooth
2% power amp
2% google chrome
Time 1D 0H 55M 45s On battery (still35% remaining)
this battery will still last another 10 hours, total usage will be around 36 hours and i used LESS standby/idle time than you, hense i'm getting far more out of my battery with less mods. im running V20c liquid nitro V6 wind kenerl v3.0 with NO BATTERY APPS (battery apps usually consume as much energy as they save sometims more sometimes less depending on system environment) the stock battery saver on this phone doesn't even turn on until 30% battery so mine hasn't turned on yet, but all it does is disable whatever services u want once phone reaches 30%. if you want to get more out of your battery, just run an efficient rom, calibrate battery properly (ask me if u need info) and be smart with what apps you install.

i'm gonna let the battery run under 5% then take a screenshot

The FD tool actually doesn't stay resident it initiates a script that starts at boot but I would be interested in the other tools you have used as it might also work on other OS's as I am playing with 10.1 right now. One word of caution I have been told by devs on this site that battery calibration does more harm than good. Also I haven't been able to run v6 phone keeps rebooting
One more thing what battery are you using and what was your on screen time? Well I guess that's two

Yeah these batteries don't like to go all the way to zero. I've owned 9 android devices and have tinkered a lot- the conclusion I've drawn is that you get a nice placebo effect from "calibrating" the battery.

i tested 3 batteries, their life on standby and running video from 100% to 0% and all 3 batteries had better life after calibration, in every test. call me crazy but it seems to work. the only explination i can come up with is that people don't do it properly. i got my battery wipe procedure from this page: i did exactly what he said to calibrate my battery i tested 3 differant batteries and it helped all 3 one of them got 15% more life on video playback and 35% more on stanby after calibration.
http://www.droidxforums.com/forum/droid-x-hacking-guides/14714-how-optimize-battery-life-speed.html
step 3 is battery calibration. EDIT -> this step is found under section 2b Operation System.
note: i am not agreeing with everything on this thread i'm just saying that i tested batteries after using those steps for calibration and they all performed better after.
side note: it would be interesting to test what the battery lifes would be if i was to wipe the battery stats in CWM whent he battery was 50% charge. then let randomly charge it without doing the proper full discharge and recharge, and see if that ruins that battery life. i suspect that it would, and this is why people think it harms the battery, im not an expert this is just an assumption. my testing was not extensive enough to prove this only to prove that the batteries i was using had better life on the roms i tested them on in both video and standby after calibration.

few things i want to point out.
i used my phone more (less standby and more screen usage)
i got longer battery life.
i didn't waste 7% of my battery on juice defender
i used more apps and media tools.
i'm using stock battery and my rom is linked in sig
i had wi-fi or data on 24/7 sometimes both
stock battery.
as i respect other peoples opinions my science background leads me to lead towards strong evidence until i see stronger evidence supporting another theory.

here is battery at 7%
*edit* for the purpose of this test i turned off the stock battery saver (the thing that turns off wifi etc under 30%) at 32% so it never even came on

Really dont know about battery times of the Note II. But do battery cycles. Let the phone turn off by it self then recharge to 100% a couple of times. And I recommend you downloading BetterBatteryStats to see what really is eating your battery out. Post a screenshot of it and post it, let some of the BBS veterans diagnose the problem. With what I know I can help. BTW you on stock/stock (ROM/kernel)?

Looks like you have ****ty signal most times. If you're on wifi most of the time turn off mobile data and use wifi calling if you need. If you turn off mobile data and it still dies that quick somethings wrong. Also juice defender can oftentimes have a negative effect, try it without. Also, you used your phone almost continuously. 5 hours screen time out of 8?

Really dont know about battery times of the Note II. But do battery cycles. Let the phone turn off by it self then recharge to 100% a couple of times. And I recommend you downloading BetterBatteryStats to see what really is eating your battery out. Post a screenshot of it and post it, let some of the BBS veterans diagnose the problem. With what I know I can help. BTW you on stock/stock (ROM/kernel)?

Don't cycle your battery. Will only hurt your battery not help. System Tuner also works nice to tweak a few things and add some battery, Better BatteryStats is a great tool as well.

I have bbs also Im new to it but Im just not sure what im looking at but here are some SS's below

Yeah juice defender is causing a ton of wakelocks. Of course, again you seem to have zero data connection or signal most times. If you use your phone almost constantly juice defender will def have a negative effect. I know from experience.

Ok. First uninstall Juice Defender its only making it worse. When not using GPS turn it off. You have weak signal plus GPS on thats 3x the drain since its always looking for location. Again same with WiFi. When not in a place with it turn it off.

Good to hear! Also screen brightness has a lot to do with screen on time.. It not the same 3h of screen on time with 100% brightness than with 30%. The less bright as possible the better buddy.

+1 100% brightness is awesome but a major killer on battery when you don't really need it.

Its better than that one day however I did not begin to use it intensely until later on at night and just played a few games of ruzzle on wifi and it dropped about 15% within the 2 hours so its a so so solution as of now I ordered a gold battery with 4200mAh of power hopefully that'll show some improvement

I'm runnng the international XXDMB6 based ROM on mine and currently, I'm at 76% with only an hour and 3 minutes of screentime?
I don't use Wi-Fi.
My LTE signal is rather poor.
My screen generally stays around 50% but it's on auto.
Of course I let my apps sync. But that's pretty much just gmail and facebook.
I have my weather set to sync once every hour.
I uninstalled the apps that are pretty much bloat (flipfonts, the hubs, the samsung live wallpapers, musicFX since I use DPSManager, Samsung's music app and that's all I can think of)
I'm running Perseus's kernel with about 200-350mV undervolts.
Is it truly the poor LTE signal that's taking such a toll on my battery life? I used to average 5-5.5 hours before my battery dies. Now I'm betting I'll only get around 4. When I had Verizon, the power draw from LTE was unnoticeable from 3G. Is it really that different on GSM phones?

I found Battery Drain Analyzer helpful. I kept it running for a couple of months and was able to determine which apps consume the most power (widgets, by far). But, after having spent weeks trying different underclocking configurations and apps without success, I ended up buying three extra batteries. It's really awesome to not have to worry about it. I just keep them in my pocket and swap them out as needed. It's not a very technologically advanced solution, but, it sure is effective. I use this Charger for the spares. It takes a long time to charge the batteries, but charges them fully to 100% and I believe that the batteries hold the charge better, whereas, charging the battery in the phone doesn't seem to work as well.
If you would rather go the tweak/underclock route, I agree with the others that Juice Defender does more harm than good. I had better luck with SetCPU.
But, as stated above, I eventually opted for high performance and extra batteries. For me, the ability to run the phone at full speed, to multitask smoothly, and generally to be able to take advantage of the device's full technological potential is worth the cost of the spares. And, not insignificantly, now that I am no longer spending time on trying to increase battery life through hacks/tweaks/apps, I have more time (and speed and processing power since I can overclock without concern) to flash, mod, tweak, and customize all the other aspects of my phone.

LG G4: Battery Drains 1% Every Minute

Hi guys my lg g4 is draining battery about 1% a minute when in use. Simple things like texting or web browsing cause this. This is a serious problem. My previous phones never did this. I dont know if this is hardware or software related. What can be the solution? Samung s6 has a smaller battery but outperforms the G4. My brothers iphone 6 plus has better battery life too. So i want to know what is wrong with the G4 which has the biggest battery out of the two.
Sent from my LG-H815 using Tapatalk

Same problem for me.. have to use spare battery and power bank when I'm not home. Drains super fast.
Also, you can't compare to iPhone as the software is super optimized and the hardware not the same (power friendly CPU and not the same amount of RAM). Plus they added some features to improve battery life.
I can tell, as my bro owns an iPhone 6 Plus too, the SOT is insane.
While doing same activities for 1 hour, my G4 is down at 75% and his iPhone is ~90%. On a day away, his phone lasted without problem while I struggled with my equipment to get 6 hours of SOT.
Meh.

Well the iphone aside but lets compare the galaxy s6 for instance. It has a more powerful cpu and smaller battery but still outlasts the g4. I don't know what is causing this. The operating systems are the same. Both running the latest os possible but getting different battery performance. I believe its a hardware problem more than software. What do you guys think? Can it be software problem?
Sent from my LG-H815 using Tapatalk

Something is wrong then gyus. I get almost 1h SOT from 100% to 90% web browsing.
Maybe is some rouge app or something else.

agree with chaki-, I'm currently ad 75% with 1h screen on time using HSDPA/4G connection. something is messing up your device.
you could try factory reset and monitor your battery life without installing any app to check whether it's a hardware battery problem or not.

Im running the latest os possible. I dont get how samsung s6 can have longer battery life compared to the g4. We have a bigger battery plus the s6 has a more hungry cpu. So how is that possible?
Sent from my LG-H815 using Tapatalk

I have found that Google photos does drain mine. I have to keep going into that app and change to backup on charge only. Otherwise it just keeps going and going. Battery drain with that is like 2% a minute

I understand you might have to disable certain apps etc but im talking about general use. Straight compare with the galaxy s6 our battery performance lacks. I dont see how that is possible. We should have much better battery life compared to most phones.

Neither do we so start posting your battery usage screens. preferably at the end of a battery cycle. no point posting at 80% or 50% left we want to see what it is at 10% or whatever low point at which you decide to recharge.
do you see any items above 'screen' in the battery usage list. if so, click them and screen shot them too.
You did not mention whether your usage is wifi or data, mixed ? what is the split.
Oh and is this a new device you just got. How many recharge cycles have you had so far.

Screen discharge on is 119% and when its off its 57% (!)
why ?
do you have many widgets that are updating. what about your wall paper. Is it custom, how big is its file size ?
This is just one thing that is killing your battery every time the screen is off and when it is on.
Try removing widgets and using a very minimalist wall paper, run it a couple of cycles and then tell us what your screen discharge figures are.
Also, you can't compare to iPhone as the software is super optimized and the hardware not the same (power friendly CPU and not the same amount of RAM). Plus they added some features to improve battery life.

iphone has an auto-lock feature which allows it to sleep without being disturbed. There are equivalents in android but not built into the system.
it also allows to restrict apps from refreshing in the background. If you can do the same you will get the same result if not better.

Just a few widgets used with Smartbulletin display and the stock one with clock+weather. Also, wallpaper is Sony default animated, I got the apk working from my previous Z3. Color is black.
On the other side, boot is managed so only few apps can start and ops too thanks to Xprivacy + hidden menu.

Do an experiment, remove ALL widgets and use a simple wall paper. not live. file size of wallpaper must not bigger than 50kB.
Do two charge cycles. post your screen discharge on/off. also post your gsam.

I most of the time use 4G. However my point is a straight comparison to the S6. With both running the latest os possible and same usage style. So i dont understand how the s6 comes out on top with a more hungry cpu and smaller battery. What is wrong with our device? You would think we should have better battery life compared to the s6 or even the note 5. Its upsetting to see the phone lack in battery performance

This will kill a battery quickly if the signal isn't good. Relying on signal bars isn't enough
The way to tell how good your 4G signal is to go to settings->general->about device->status-> look for signal strength
there will be a figure there in dBm. How much is it ?

Its not a signal problem. I have already isolated that from the start. My comparison was with the s6. How can it last longer when we have a less hungry device with bigger battery

Because something is draining your battery faster than on the other device. As to what that 'something' or 'something's remains to be determined.
state your sot and total run time.
Btw how long have you had this device ? how many times have you charged it.

2 months i had it for.

I can see lg g4 is not power efficient like the s6. So we can never get the same battery life as the s6. Even though we have a bigger battery. This is really unfair.

what is your avg sot/run time. when on wifi and when on data. second time i've asked this basic question.
in two months what have you tried to do to improve battery life.

I tried to minimise brightness to about 30%. Deleted all the extra apps. Updated to the latest os. Updated all the apps on the phone to latest available. So something is wrong with the G4 in general. From what i read on the tests professionals have done is that the G4 isn't efficient like the s6. So this must be totally a software related problem. Os is not optimized to be efficient. This device has let me down in regards to battery life. I would most likely want to go with another device probably the xperia z5 premium. However i dont know how the g4 would perform with the marshmallow update. That is something we have to wait and see. Hopefully LG do a better job at it this time.
