[BATTERY]Tips for better battery life

Here i would be presenting a thread in which i will be talking about how to get the most of your battery on our beautiful phones. It is a fact that at this moment of time battery is not that great on the HOX. But hopefully with the tips that i will present here, shall help people get the max out of their battery till we have some custom kernels drop our way. So without further or do i present a few things that you can do to get the most out of your battery.​​​​
Tips for better battery life​
1) Touch screen sounds and lock screen sounds untick them from Settings-Sound. That causes the audio_out1 wakelock and unfortunately it is here as well on the HOX and drains battery like hell. So untick those so you do not get that massive wakelock
2) If you are using stock rom and have not rooted yet you can use this option to disable bloatware. Go into settings-apps and go into all. There you can select the applications you want to disable. What that does it will not unistall them but freeze them like TB does for rooted phones. It will remove them from the background and from your app screen to. Pretty nice feature if you ask me. Mainly disable your carrier apps and the google ones as well like Play Books, Play Movies and Play Music if you do not use them. Just a small addition to be added thanks to (pnnorth)- If there have been any play store updates to the app, you will need to uninstall the update before it will show the option to disable the app (eg facebook)
3) If you are using Titanium Backup(i always recommend to get the Pro version) you can uninstall those apps or freeze them if you like. For me i personally would uninstall them as they do not have any use for me.
4) If you are at home and you want to browse the net on your phone always make sure you use Wifi. It is a no brainer that wifi drains less battery than 3G. So always have your mobile data in settings as off and just use wifi. When you are out and about though make sure you have wifi off and use your mobile data on your phone instead. Because if you have wifi on as well it will try and scan for the available networks it can pick up and that causes drainage on your battery. Have that off when you go out.
5) Regarding brightness. Make sure you either have it on low settings or auto. It is a fact that if you have max brightness for your display that is a battery killer as well. Settings-display-brightness and just adjust from there.
6) Regarding task killer apps or battery saving apps like Juice Defender i recommend to stay away from those. Those apps consume more battery than they are suppose to be saving. Regarding task killers it is NOT recommended to kill apps because Android does that for you anyway. Just make sure you the application that you use, you always use the back button to exit the app or just go into multitask and swipe it away.
7) If you are rooted make sure you fully charge your phone and then in recovery or from Leedroid tweaks if you are using that make sure you wipe battery stats. That always helps as well.
8) Regarding sync your accounts. Now i have mine on autosync. From reading around having to sync your email account and facebook and twitter and whatever account you have syncing that drains battery. Now you can do two things. One either set the option to have those on manual sync or if you do not use facebook then uninstall it. But to be honest i have everything on autosync and still get good battery so it is down to user preference really. But for those interested go into settings-accounts and sync and adjust to your choosing.
9) Switch to gsm/2g only instead of wcdma/3g in settings >mobile network >Network Mode. Specially if you're not planning to use any 3g internet/mms features. (thanks to Gdelrosario)
10) Try to avoid ad supported apps. A research showed that in apps where there is adds, 70% of the power use comes from downloading and managing those adds to your screen. 30sec use of an app that uses adds, might drain your fully charged battery 0.35%-0.70%. Research link found here (thanks to Tont0)
11) Settings > Developer options > Windows animation scale > "Animation is OFF".
12) Mentioned this above but will re-post here again with a bit more detail. (thanks to AndroidGX) If you have multiple mail accounts, turn off auto-sync feature to refresh them manually. Settings > Accounts & sync > Auto-sync : [UNTICK]
Note: this will works also for any app like Facebook, Twitter, Beautiful Widget, etc..
13) Disabling the options for louder ringtone when inside a pocket and stopping the ringtone when picking up the device might also help. (thanks to Hardstuffmuc)
14) Settings > Wi-Fi > Advanced > Keep Wi-Fi on during sleep : "Only when plugged in". That way wifi will not be on all the time and that means saving bit of juice in the process

*Another great thread to have a look at is the Rom Cleaner by Patrics83. What it does it basically gives you this option : Will remove as much as possible without breaking HTC Sense Launcher and Widgets! This is the best way to come close to a no-sense ROM and still use HTC Sense!

That is it for now. I will be updating this thread when i come across more battery saving tips. For now if anyone has anymore please post them and i will add them to the OP and give a thanks to you by adding your name next to the tip.

Was going to compile a list of apps that are safe to disable (for non-rooted users) and what to freeze uninstall (for rooted users). But since there is Rom Cleaner thread by Patrics83 as i have stated above you are probably best to go to his thread here where you can use his script and follow the guide on OP. This is script is for rooted users.
There also you can find a list of applications that is safe to disable for all those who are non rooted. Settings-apps and then go into all apps. As pointed out in first post tip 2 first if the application you are trying to disable has been updated first uninstall the updates and then disable the app
That is it for now more will follow

6) Regarding task killer apps or battery saving apps like Juice Defender i recommend to stay away from those. Those apps consume more battery than they are suppose to be saving. Regarding task killers it is NOT recommended to kill apps because Android does that for you anyway. Just make sure you the application that you use, you always use the back button to exit the app or just go into multitask and swipe it away.

This is not a task killer. Also the apps are not aktive in backgraound, they are hibernatet. If you want to kill a task go to task manager.

Juice Defender=Battery Saving App = Not so much of a battery saving app
And Maps, and even facebook are active in the background my friend. by disabling them you are kinda like freezing them anyway. And yes if you read above if you want to kill a task or terminate an app i did mention that you can do that through Task manager. Or even by going into multi tasking app and swiping the one that you do not use anymore exits the app my friend
Trust me i done my research before posting this thread. But i am also open to correcting something if i am wrong.

Just a small addition to point 2) - If there have been any play store updates to the app, you will need to uninstall the update before it will show the option to disable the app (eg facebook)

I already made another thread posting this one, but as I noticed there is one where to gather some common tips, I might as well add it here.

Here is the link for the research http://www.androidauthority.com/ad-suported-android-apps-battery-drain-65716/

Very good thread. I tend to do most of what is mentioned anyway. As soon I got the phone I was busy tweaking the settings so that I could get the maximum power out of the battery. I'm not considered a heavy user anyway so it typically lasts 2-3 days.

you can also add to switch to gsm/2g only instead of wcdma/3g in settings >mobile network >Network Mode
specially if you're not planning to use any 3g internet/mms features

Cheers guys...Any tips that we can get i can add them all to the OP so that way we can have one thread which has everything. That way no need for clutter of threads regarding on how to improve battery life people can come here and read and discuss. Thank you guys i really appreciate your help

Added the new tips to the OP. Thanks

Qn: Are all battery saving apps not actually saving battery then? (E.g. Juice Defender)

wiping battery stats is done when reaching 100% charge and holds nothing but the useage of apps and does nothing to calibrate or improve battery life.
heres a quote to back this up.
Deleting this file will basically wipe your battery usage reports, which is done anyways automatically when the phone is fully charged (hence you'll see a clear list when you reach a full charge). "Deleting it is not going to do anything to make your more device more fantastic and wonderful".

i will be honest with you. When i had my galaxy s2 and i had juice defender on that drained more battery than it was suppose to be saving. I could find you posts from users and kernel developers that i know from the s2 forums that advice against it. It is down to you to try and test but from my own testings i would advice against using them

True. You do have a point. but also on the other hand there has been people that saying by wiping battery stats that deletes the battery history makes everything start fresh as you mentioned above. What i am trying to get maybe it works maybe it does not. But one thing i know from my own experience by deleting those battery stats did help a bit on my battery. Hence why i posted that in the OP.

Like i said mate. In general i have not bothered with battery apps. For me they eat more battery than they are suppose to be saving. If you follow my guide and also search on xda to find more threads like mine most will say that battery apps really do nothing..But it is down to you at the end of the day.

That is easy to figure out. Most of the times it will be all the free apps in the market. If you are rooted install ADaway and that will install the hosts on your phone and will block those ads.

[Q] Battery Life Problem

Recently, my HTC One X has constantly been dropping with battery. It would go from 100% to 30% or 20% without me doing anything.
Any suggestions why?

Listen yeah, how you're a senior member is beyond me. If you want to help, send me a link or something, if you don't, don't bring yourself into this thread. I am eligible to post threads based on my concerns, therefore I should receive some assistance, and it's fine if it's not from you. There is no need for you to reply with such frustration. Thank you.

You become a senior member if you make 100 posts.
Anyway, it looks like you have an app which is keeping your phone awake a lot. That's the reason for the quick drain. If you go to Settings>Power>Battery use you'll see that your 'Awake' bar is full most of the time. There's an app called BetterBatteryStats in the Play Store. It also has a thread here on xda with an xda-members-only free version. This app will give you a lot more detailed info than the default Android battery usage screen. You can find out what's keeping the phone awake (called wakelocks) and uninstall that app. If no app is keeping your phone awake, then the reason for your quick battery drop may be a failing battery. In that case you'll have to replace the battery.
Also in case of battery posts, if you're using any ROM other than stock, it's better to mention your ROM name and CPU governor and frequency settings.

Plz Mention R u on stock Rom or on other and also tell me ur usage pattern like ur wifi/2g/3g always on when ur phone is in sleep mode ?

That should do a lot of good, yes. Because you'll have a fresh system and you can watch what apps you install. Especially be careful about apps with low ratings and low number of downloads. If this is still happening, then let BetterBatteryStats run from a full charge to empty and take screenshots of the overview section and wakelocks section.

About three weeks after originally purchasing my One X, it did exactly this, with battery life tanking. A full factory reset cleared the problem, along with a complete battery charge cycle. Haven't had any issues with battery since then - 6 months ago now.

Put your phone on flight mode or get an app that organizes when your phone should be out of flight mode. I put mine on flight mode over night and my phone gets sleep at least 97percent of the time.

Switch back to a 4.1.1 Rom

I have been saying this to each and everyone.
Don't revert to roms released before and in December.
The update in January contained a sds bug fix. It was a very critical bug.
Don't take for granted that Samsung will repair your phone in case of an sds bug issue. They may even say no and you'll be crying then. For God's sake don't downgrade.
Just imagine if you lose 5 months of messages, WhatsApp and what not.
All your pics. It's not worth not charging your phone everyday.
What's the problem. Just leave it charging overnight or when you aren't using it.

The problem is I only got the note 2 for the battery life. I don't want to "settle" for a battery draining update. If I wanted to charge it every day then I would have got the htc one x+ or nexus 4.
Samsung better fix this soon.

Ok then you can play with it's battery when your phone dies due to sds.
Good luck and best wishes.

Hahahahahahaha Btw that advice is actually quiet sound, its better to be on LL7 or later with worse battery life but the sds bug fixed than being on earlier stock ROMs with cgances of sds.
Btw, I am on Indian MA6 and this works as well as the LL3 used to for me atleast.

I'm still on 4.1.2 and unlikely to change back to 4.1.1. This is 99% due to the fact the browser in the older versions doesn't reflow text (like Nexus or HTC). Also, unfortunately due to the clowns at sky putting strict restrictions on their "Sky Go" app, it is not possible for me to use any of the custom roms as the app just does not work on them and there is no way around it.
I have to stick with stock and hope this drainage issue is sorted in the next update!

I normally don't use the stock browser. Somehow have always preferred Dolphin. And as for the Sky thingy, I am actually trying to make my sister in London kick Sky away cos they so blatantly support Apple products over Android devices. I am not sure if this is the case even now but some months ago their apps refused to run on Android tabs, and worked only on Phones.
Edit : I just thought of this, you can always flash 4.1.1 stock right? It isn't as if your phone status will change on just flashing a stock ROM on an unrooted device. And even if it does, you can change it back to normal using triangle away and all. That would allow you to use sky without any prob.

I always used Dolphin too but doesn't support flash on JB. Have to do a titanium backup and restore of the ICS version to get it to work and it seems every so slightly buggy.
The reason I don't go back to 4.1.1 is because it doesn't support text reflow. Similarily, ive always been rooted and need to toggle it on and off because I use apps like directorybind given Samsung's idiotic decision to use the internal memory as "SDCard"

If you are rooted, and sky does not work on modified devices, how do you get it to work? I need to get some apps feom my office to work on my root+stock device, but they normally don't start, displaying a message that 'Your device is modified'.
I tried directory bind for sometime, but found it to be a bit of a headache. Instead I use a simple script with ROM manager lite to switch external/internal storages. Found it on an external site, works flawlessly. I don't even have to backup game and audio/video data and when I flash a new rom now.

[Q] AudioOut_2 partial wakelock drains my battery

Hello, I know, on XDA is a lot of topics with this problem but I didn't find any solution there.
Some days ago I flashed my device to stock ROM 4.1.2 [XEO]. Of course, I made full wipe before flash and I didn't root my device.
I installed apps which I use and problem is here. I read, Viber is draining battery, so I went to settings of Viber and checked "Use System Sounds" and disabled vibrate when somebody sends me a message.
In android settings I disabled system sounds and vibrate too.
List of my apps:
Code:
AirDroid
Any.DO
Apex Launcher
BetterBatteryStats
Business Calendar
Cerberus
Dolphin Browser
Dropbox
Dropsync
EZ File Browser
Facebook
Feedly
Keep
Messenger (Facebook)
MX Player
PicsArt
SMS Backup & Restore
SoundHound
Swapps
Tapatalk
Tasker
Tinylight
Twitter
Viber
Waze
WeatherPro
WidgetLocker
Zooper Widget Pro
At night, tasker turns my device to airplane mode from 03:00 - 07:30.
Battery is really important for me so I will be really very thankful if somebody helps me to fix my problem with drain.
Here is BetterBatteryStats screen:

Look in da guide in mah sig.

Thank you for your answer.
Tip 1:
- doesn't work for me. I wrote to CurrentWidget support. They tell me, problem is with Samsung devices (still shows 0mA)
Tip 2:
- have all disabled / enabled
So I found, I must close all aps before I lock my device or use Advanced Task Killer. I read a lot of articles and they don't recommend use 3rd task killers apps and auto-killing is bad for android. So I don't know what I can do now.

Bs. If you configure it to automatically kill all apps at screen off then nothing is gonna go wrong. I have set it up and everything is good here. Also use greenify to stop apps from running in the background that you don't want.

I just uninstalled Viber, hope, it will fix my problem. / installed Whatsapp

I had this issue, i downloaded installed and ran "Rescan Media Root" from the Google Play Store. Problem solved. Without having to uninstall Whatsapp or Viber etc.

Thanks but I don't have rooted device. Btw still have AudioOut_2 problem.. BetterBatteryStats shows me 15 minutes of AudioOut_2 now..

It is not Viber, despite what many people say on numerous threads.
I uninstalled Viber and the problem is still there.
To this day no one knows what the cause is. There have been many suggestions but no definite answer.

And to make it more difficult to solve, it looks like it's completely random.
I hate this kind of problems, the intermittent ones...

It is due to any app that uses audio. To shortlist it is generally in apps that use audio and continue running in background.
The only solution is to kill all apps before letting it sleep.

Thank you for all replies. Hmmm today I get good stats of battery and AudioOut_2. I don't understand

I can personally confirm that both Viber and Skype (when signed in) cause this wakelock. Also, this wakelock appears regardless of whether you turn off your screen. Play 15 minutes of audio with the screen on, you get this wakelock. Play a game, kill the process, you get this wakelock. It occurs even if you're using the phone, not only during screen off.
Edit: What I meant to say was, Viber and Skype cause this wakelock during screen off time.

Some hours ago I sent some messages via fb messenger and whatsapp, read some topics in tapatalk and read rss via feedly. AudioOut_2 is high again.

Basically an instruction to the CPU that stops it going to deep sleep. But try what I said, set a custom reference in Better Battery Stats, play music for 15 minutes while using the phone. You will get 15 minutes of AudioOut_2.

I have the same findings as you. Get lots of AudioOut_2 wakelock but it actually corresponds to the time i spend playing games with sound on (which obviously happens when screen is on). And even with high amount of this wakelock, i still get my normally great battery life. Hence i conclude this wakelock is wrongly captured, at least for me. :cyclops:

Getting high audioout_2 while playing music or games or anything else which produces sound is of course normal, it's common sense.
The problem is when you have 8 hours of awake time when you're sleeping due to audioout_2. My battery went down by 11% overnight because of this.

So you want your cpu to go into deep sleep while you are using it?

Just configure advanced task killer and greenify. That's all you'll need.

Hello UtkarshGupta,
so I tried to install Advanced Task Killer and here is my setup:
In settings I checked Ignore service, fron app
Auto Kill Level: Crazy
Auto Kill Frequency: When screen off
I created recommend ignore list and add some apps but I don't know if I can kill for example Clock too.
BTW I see S Suggest and S Voice are runned. I don't know why, coz' I didn't start these apps.

I don't have any ignore list. In fact I deleted the ones which were pre configured. I don't have any issues.

but i.e. I'm using WidgetLocker or Apex Launcher. If I kill one of these apps, it will be not a good solution.. hm?

How old is your GN2? Age also degrades battery.
You can try Greenify to hibernate all user apps (but not those which you need notification from.) You can also try to freeze unused system apps using TB Pro or other free apps (there is a list presented somewhere in the DN3 thread, try search)
Goodluck.

about 4months , so i don't think its the age

For battery capacity is warranty for 6 months.
But use Wakelock Detector or Better Battery stats and see the results.

Use the app battery life repair. It activates the inactive cells in a battery. I found it to be useful.

Firstly, there is no reason to put all your writing in bold.
Second, your battery is either dying or you have too many things running in background. Check to see if you have backup services like picasa etc syncing without you realising. Go through everything and turn off the things you dont need/want.

Re calibrate your battery. It will help. There is an app called battery calibration in play store. If that doesn't work you can try manually. I forgot the method though. It really helped me
