Today I decided to do a real world test of the Evo's battery life. I used my phone the way I would normally use it on an other day. As for the phone itself, I am running the rom from the OTA update. The only changes that have been made is that I am using unrevoked root method so that I can use the Overclock Widget (marketplace) to turn the processor freq down to 245000 when the screen is off. I also use Advanced Task Killer to turn off apps that I am not using. I had bluetooth and gps turned on throughout the entirety of this test, wifi was on for about 3.5 hours. During this test I played a game for a short period of time, did some light web browsing, and had several phone conversations that totalled a little more than 2 hours. With doing all this, my battery lasted for a little more than 11 hours. That being said, under normal use the Evo should definitely last you throughout a full day.
Thanks for the info. I got my Evo yesterday and haven't been able to put it to through extreme testing yet
No problem. just kind of got tired of hearing how poor the battery life was. Even before using the overclock widget I was still getting decent battery life, but the overclock widget just put it over the top. To add to that, I don't normally talk for 2 hrs. on my phone during a normal day, so really a lot of that 29% battery drain from phone use wouldn't be there. The only thing I didn't use today was 4g (which I don't normally use unless I'm on the phone and need to use data).
Not sure what this proves or "dispells". When people (myself included until making some friendstream changes) are getting 6 hours out of a charge with light use, that is a real problem. You must not have friendstream syncing...if you did and did everything you just wrote about, your phone would be dead in 3 hours tops. Thanks for the info., but once again, people are havnig real issues with the battery...it's not made up.

If you are experiencing poor battery life then it is most likely attributed to not managing your apps properly (friendstream included). For example, without advanced task killer you will get a drastically different amount of battery life than if you have it. Then add to that, the way you configure advanced task killer can add a large amount of battery life compared to having advanced task killer without it being configured properly. Even with friendstream running you should still be able to get a decent amount of battery life (I am aware that it does use more juice), try having your facebook sync less often.

I totally agree I've been using my evo and been fine, I only really have it connected to power when I have it tethering. Besides that it lasts me not all day but while I'm at work (which is the most important part) I get a good 9-10 hours out of it before I really need to charge. It should also be noted that I use locale to switch BT and wifi off when I'm not in an area to take advantage of them.
I think some people have bad batterys/evo's, it's not just a matter of running the right programs or killing tasks

While that is possible I think the majority of the problem rests with the user's mismanagement of apps. I have seen way to many posts from people declaring the battery life to be so horrible, only to make a few changes and then turn around and say how much better it got. If that person had a bad battery then the battery would still have been bad, it wouldn't just start being good. That said, it is very possible that there are people with bad batteries. I just think that most of the people have good batteries and bad phone management.
I did pretty much the same thing. I have the O/C widget to set the frequency to 245000 when the screen is off and also have Advance Task Manager configured to close apps I'm not using. Helps out a lot and I usually get around 12~14 hours on a charge.

While I completely understand what you are saying, I can't really agree that b/c someone is not getting a full day out of their phone it is b/c of poor app management. While deleting facebook for sense, then reinstalling with only contacts synced fixed everything for me, the fact that you have to go through the phone with a fine tooth comb to get it to run more than 6 hours at a time is pretty silly. While doing that stuff is fine for me and most on this forum, it will undoubtedly turn a lot of non-techie people off from this phone...especially with Sprint doing their new 30 day full refund policy.
It's all good though, just plugged my phone in after 19 hours...playing with it most of the day.
I use advanced task killer and turned off sync for apps I dont use. At 65% used pandora (in 4g for about an hour), browsed several sites, made phone calls, text, emailed. All the normal stuff. Took my phone off the charger 15 hours ago.
Prior to using advanced task killer I would be to about 18% right now. So for those saying that task managers kill more battery power my phone seems to do the exact opposite.

Task killers really only help if you have an app that would normally be giving you higher than usual wake time (the calendar comes to mind). At the start of every boot I always make sure to kill everything so only essential apps and those I use are running. I don't use any kind of auto kill.

It is no longer recommended that a task killer be used. It may result in poor phone performance.
After i rooted with Toasts method, installed OMJ's rom removing all of the sprintware and added the OverClockWidget to tweak the processor, i was able to go a full 32 hours without charging. i had gps and bluetooth on the whole time and wifi on for several hours. i made calls, sent texts, took pictures, basically normal usage.
Just to add to all this. Bad battery isnt just a HTC Evo problem. Go read the forums of almost every android phone released and they all report the same things (in the beginning). Someone that has had a android phone in the past probably hasnt said much about battery. There are so many things you can do to increase battery.
1. manage your apps. Exit them instead of leaving them running (press back button until the app closes, or some apps you can Menu> exit) Pressing home doesnt close the app, it only takes you to the homescreen. Also change the sync times of all your apps/widgets. If you dont use gmail or google calendar, then uncheck the "sync" in Menu>accounts & sync> google. One last thing use a task manager (not recommended by some devs) I use it to end tasks of apps that use data, or ones that i use maybe once a day or once a week, i dont need them cached for quick returning, so i end the task all together. I ignore apps so they dont end that i use very frequently or ones that dont use data or run in the background.
2. Calibrate your battery once like so.. Charge your phone to 100% and then use your phone like normal until its so dead it shuts off by itself. Dont plug it into the computer or wall charger in that time. Then once it shuts off, plug the phone into a wall charger and charge it till its 100% again. After that, plug and play as much as you want.
3. Buy a car charger, usb cord for the comp, and maybe another wall charger. Buy an extra battery or extended battery. Doing the above and adding these to them, youll have a huge increase in battery.
I have an htc hero and i can get well over 12 hours of use by just watching what syncs and what uses data. And i use my phone alot, and wake it up a ton to check for notifications.
I use a friends Evo so im not new to the device and I understand its a different phone.
Stock htc phones come with a lot of stuff preinstalled and widgets. When signing into them with your accounts the sync times are usually pretty high, some like every 15mins. Watch what you are doing with the phone and youll have normal battery life.
i avg 18 -19 hours per charge so im very happy
aaaaah ok now I know who is the idiot Dylan here. Thanks. What a dumbass know-it-all.
I think some people are getting poor battery life because intermittent signal. I know this was the case for me. When I go to a friends house that I barely have signal, the phone constantly tries to find signal or goes into roaming. It would drain the battery fast. When I was in good signal area it seemed to last quite a while. Just saying that it is more than just running apps that cause poor battery.
Also if you will not use the internet turn off the mobile network, put the widget in your screen. You can receive calls but the internet is off.

You make a very good point. Weak/no signal areas will drain your battery (as with any phone) very quickly due to the phone constantly scanning for signal. Not really much you can due about that other than turning your phone radio off or switching carriers lol. One thing I've read in the Dev forum that may help you is to change your prl to the Alltell/Verizon prl. Some people have reported that this works well in low signal areas.
I've had the HTC Aria for about four days now and my biggest issues is the battery drains to quickly. At first I attributed it to use because android phones prompt you to use them more often. However, even without use it still drains pretty rapidly. Does anyone know of a solution to this issue software wise. I have already turned off Bluetooth, GPS and Wifi. Are there other solutions
I got mine on Saturday, and I've actually gotten pretty good battery life out of it. I'm still in the habit of charging it every night, like I had to do with my old WinMo phone, but I think I could probably go two days without a charge. And that's with GPS / data always on, Wifi parts of the day, and pretty heavy use, since I'm always playing with it.
Have you tried something like Advanced Task Killer to keep apps closed that you aren't using? You can also adjust your screen brightness and timeout to try and save power.
It says that of my power is used by cellular idle or something like that 50% of it was used by that. Could it be my AT&T service
I don't get more than 10 hours out of mine. When I know I will be out all day, I turn the screen brightness almost all the way down to help conserve energy.
Good as it Gets.
With basic usage (some texting, a few calls and some market browsing or playing a game here and there) about 2 to 2.5 days without charging. Maybe the ones having issues with there phone sucking battery have to many widgets running.
In my current configuration I am only using 3 of my screens and only 3 widgets [favorites (small one), HTC clock/weather widget, and the HTC calendar widget (small)]. I have my work email checking every 30 minutes for syncing. I also have gmail and the default mail app pulling mail. I run ATK but only to kill apps on startup (cause it runs almost everything), other than that you don't need a task killer as you will have to reload these tasks next time and that will drain battery. I don't use it after that to kill anything. I am also running my screen at about 30% brightness.
Just some tips, widgets are nice, but they suck the battery life as well as constant updates. Check to see what you are running and disable/remove what is not needed or adjust sync times.
My battery life is fine. I got two days over the weekend with light usage. You need to look at what services are running and disable any widgets that you dont need. You may also want to look at the sync settings and turn off things you dont use (such as news). You do not need a task killer.
Also, see this post:
cranked said:
some quick tips:
1) disable market notifications - Market -> Downloads -> Notifications -> 'Don't Notify Me
2) Lower the sync times for your social network apps like twitter and facebook (or make them manual)
If you still suffer, have a look at some of the great tips HERE on the Cyanogenmod forums...ignore 1 and 3.

Also one might do *#*#4636#*#* then change phone setting from WCDMA to GSM .... Then that get little more out of battery...
It's critical that you turn off auto-sync; I have found that it absolutely destroys battery life.
Before I was losing maybe 5-10% every hour on standby, but ever since turning off auto-sync, I'm still sitting at 100% battery after 5 hours of standby.
Turning off mobile data/Wi-Fi doesn't make an impact on battery life, in my experience.

I edited your response..
Auto-Sync in itself is not going to be a problem.. Depends on what's syncing. EVERYONE will have different battery life because everyone uses their phones differently. Different configurations, different accounts used, different amounts of traffic on those accounts, not to mention actual usage patterns.

90% of people will have *slightly* different battery life.
5% of people will drain it fast.
5% will use it like a voice phone and might even get 16 hrs out of it.
But to turn off all apps makes for an invalid test because then you're testing the phone as if it were a non-smartphone, like a voice only phone.
I think the battery is too small for me and probably too small for most people. I look forward to fat batteries for this great phone.

My wife gets 2+ days out of hers... The battery is not that much smaller than my Nexus One, a more powerful phone, and I'm a power user with a lot of crap running including IMAP push mail, weather syncing... I look in at Market, Facebook, Twitter and manually sync those types of things etc.. I can easily get a full day out of it, off charger ~8am back on the charger midnight, 20-30% left. What I don't do is sit staring at my phone all day or play games for 8 hours at work, nor do I use it as a mp3 player..
Before getting the Note, I've been an iphone user ever since the first one came out. I switched especially because of the nice large screen which is handy for the type of work I do.
Some questions though:
1- Battery Life: I was pretty handy on the Iphone in getting everything I didn't need (some notifications, location services on certain apps) turned off to safe battery...while keeping only the ones I wanted. I haven't figured out how exactly to do this on the Note. My battery life is poor...at least compared to what I was getting on the iphone. I typically start my day at 8:30AM, and yesterday by 6PM the battery was already at around 10% (where I can't take pictures....)
2- Must I have GMAIL app and MAIL app? For some reason the GMAIL app's emails update much quicker than the main app I use MAIL. So when a new mail notification comes in I have to manually refresh the MAIL app for it to catch up with the GMAIL app. Otherwise I would have to wait a couple of minutes of the mail to show on MAIL app.
3- On Mail App I have two email accounts. Why is it that my welcome page is the page showing my accounts rather than my "ALL MAIL" page which is where I left it originally?
Thanks for sorry for the NOOB questions.
Ad 2):
Depending on what other email account you have there colud be an specific app for that provider that also supports push email (eg. Yahoo). Or you colud configure Google Mail to poll for mails from your other accounts.
1.) try to close auto sync, bluetooth, gps and use wifi everytime its available because 3G drain much more battery. and lower the brightness on ur screen to ur lowest, that can save a lot of battery (just open them when u need to use it)
or Root your Note and use custom rom. There are many roms that help you with battery.
hope that helps.

Battery - 10% in a day??! How much were you using the phone?
Allow the phone to fully charge and discharge for a full cycles. The screen is a big consumer of power - don;t use auto-brightness and keep the screen down to the best workable level for you. Also, the more apps you have using push syncing, the worse your battery will be.
Depending on what you're using the phone for, you should easily get a full day's reasonable use out of it.
I agree with the point shaoran_ojo made about wifi - but also turn wifi off when you're not using it.
Finally, it's absolutely right that many of the custom ROMs will give you better battery life
You can check the battery usage over time, if you go to Settings menu and then About phone -> Battery usage. You will see there what eats most power (most likely, Display).
Touch the chart in the upper part of this page to expand it - see if you can relate biggest drops of battery charge to some particular activities. For example, playing Crayon Physics drains the battery extremely fast.
Do you happen to be in areas with poor cell coverage? I've had phones drain like there's no tommorow in poor coverage areas, especially when GPS is turned on since most phones are equiped with assisted GPS chips that use cell-tower triangulation in order to get a faster fix on your position.
You could root your phone and switch to custom kernels or roms for better battery life as well as performance. A few ways in which you could then save battery are by undervolting or underclocking the processor or using an app like titanium backup pro to freeze battery draining apps. Wifi is also a big battery drainer. You can set the wifi sleep policy to screen off to curb its usage or keep it off entirely when you dony need it. Gps and bluetooth can be kept off and the screen brightness can be lowered. Im sure you wont be disappointed with the note's battery life after you tweak it right.

First of all decrease the screen brightness if possible. I have my brightness set to minimum and I have Screen Filter (free in the market) installed and set to 50%. This setup works for me when I am indoors and when I am outside I just disable Screen Filter. Hopefully it will work for you too, maybe with a little tweaking of the exact percentage.
Then take notice if your phone is unusually hot when you haven't used it in the last 5 minutes. This may indicate there is an app keeping your device from sleeping. Check the battery usage (Settings -> About Phone -> Battery Usage). Tap the graph and look for unusual drops and periods when the screen is not on but the device is awake.
If you notice something, BetterBatteryStats (paid in the market) might help reveal the source of the problem. Cpu Spy (free in the market) will show you how much time has the device spent in each CPU frequency.
If you are comfortable with it just root your device and install a custom kernel. I can't begin to explain how much this can increase the battery life.
Hope this helps and is not too hard to understand despite my bad english.
Nuff Said
Dunno' about you, but after an year I started noticing the battery isn't as good as back then.
Try JuiceDefender, that's what I'm using right now and it's quite good.
Doesnt that waste more battery?
Cause it runs in the background?
Not really sure, but thats what i think.
I vote JuiceDefender as well. It has very minor battery impact for a decent amount saved (as long as the phone's on standby and not syncing a lot). You don't state what you've already tried, but with root & unlocked bootloader you can underclock and undervolt which helps save battery a lot. Delete unneeded apps, especially the stock crud. Make sure no apps are using partial wake locks (keeping the phone from going into deep sleep) by using BetterBatteryStats. Btw, BetterBatteryStats can identify a lot of things that might be draining your battery. Of course, the most obvious battery savers would be turning brightness down, turning off GPS, turning off WiFi, lowering volume, etc.
Auto Brightness on or off ?
Really? Xperia Play's been the only Android device I've ever owned where battery life WASN'T a concern.
...at any rate... here's some tips!
• Toggle Data to "Off" when it's not needed or switch to 2G/EDGE (or even Airplane Mode for dedicated gaming sessions)
• Enable Auto-Brightness
• Disable the notifications in any app that keeps your phone in a data retrieving cycle (Facebook, Twitter, Skype, Weather, etc)
• Keep GPS/Location Data off whenever possible
• Stay away from process heavy battery destroying whores like Regina Launcher, GoLauncher, Xperia Home, Fullscreen Launcher and Claystone
• Use a minimalistic launcher (LauncherPro, Smart Launcher, Lightning Launcher, ssLauncher)
• If you like live wallpapers, that's fine - but fine-tune their options so that they aren't always murdering your battery
• Make sure your WiFi connection is set to disable mobile data (this is commonly set by default)
• Be very wise about your widget usage. If you're going to use them, fine-tune their settings so that they don't murder your battery
• Give your phone a complete battery drain, then recharge fully at least once every month.
• If you're in low-reception areas that have WiFi, save your phone a lot of battery-draining connection conflicts by keeping WiFi on.
I'm using almost everything TLR suggested plus set CPU with a profile for screen off that turns the CPU down to 340mhz. Battery seems to last pretty decent for me.

TLR brightness option is diff than mine, instead of auto bright i just simply put it as low as possible. It totally savs more.
Im using a Mugen 1800 battery . Bought it last week and i easily get 20-40% more charge than with the standard one.
It lasted me for full 2 days of light usage (2 hours and 30 minutes of display time) .
Tried nearly everything on this page.BUT, does OC waste alot of battery??
Overclocking would make your battery worse. I don't know if it has a major effect though, depends what you overclock it to.

How much battery time are you getting now?
My advice, go back to 100% stock factory reset.
Then debloat.
If your phone is old, your battery probably lost some of its capacity, so you could try a new battery.

My battery is fine now, tried all the tips and made massive difference. Thanks everyone!!
I don't know if battery is different here in Aus (BST41-1500mAh), but mine is 18 months old and just by turning off bluetooth and WiFi and controlling screen brightness and 3G as i need them, i got 2 days general use (10 calls per day 50 sms and 1hr 3G web browsing per day) R800i.
Last month i flashed JellyBean following these instructions: http://forum.xda-developers.com/showthread.php?t=1801983 and now I get 3-4 days use! With this mod I can leave it in 2G mode and for some reason it still gets data via EDGE so I can still get facebook + skype messages etc. This feature and i'm guessing better control of the CPU and tasks are obviously the main reasons for better life
I would really like that rom but i need camera.
Hey guys, so ive had my nexus 4 for around 4 months now? might be more and the battery is just terrible, obviously we already know this as ive seen so many people post about it and such
my question is this, what do you guys use to save battery? Im currently on XYLON ROM with Perf-enhanced-Stock-422 kernel which isnt bad, theres nothing wrong with it in fact but i literally only get around 2 hours screen on time, terrible i know
ive heard people say flash android 4.2.2 and then flash a custom rom, apparently it helps or something? not fact but ive seen a few people solve it with this issue
What kind of roms and kernels are you guys using? And what governor?
Cheers guys, Jack
I've seen most people running Franco kernel with either cyanogen mod 10.1, PAC or paranoid android. You'll probably get a similar battery life with all of them, and probably the best your going to get.
Check your wake locks, use juice defender, check you're not dropping in and out of signal (hammers battery), turn of location settings...
Sent from my GT-N7000 using xda premium
AKOP or CM with franco give me hours (4+) of calling or 1.5 days of moderate use.
I also have notification widgets on so I can quickly switch BT/WIFI/Brightness AND I make use of nfc tags so when I'm home wifi is auto turned on and when in the car it turns off.
From my experience, these battery saving apps such as juice defender are not good, you shouldn't use them.
About the battery life, there are tons of recommendations... stop syncing, turn brightness to as low as possible, turn off 3G when you don't need it...
Dont use your phone..
Seriously now, the battery is not bad at all, and in battery usage cases you need to state your usage of the phone (games, mail, 3g on most of the time? widgets? surfing and screen on time)
Without those parameters none can determine if you have wakelocks problem / some app is draining your battery or eventually maybe it's only psychological problem
Take in mind even on auto brightness, if you are playing heavy games dont expect to last a day or so..
Tricepz is on the money!
Need to analyze Your usage!
Most importantly you need to understand that this is not a primary game console or music player.
Things that drain battery fast!
1) Live Wallpaper
2) Games
3) Phone calls
4) Equalizers
5) Apps
Best to monitor your usage!
Personally I use the phone as follows for 16 to 22 hrs of usage.
Bus
1) 4 hrs of music with quality headphones that have noise canceling tech. Abel Planet 200b with built in amplifier.
2) 3 phone calls a day!
3) No games ! Have a tablet for that
4) Minimal reader for new feeds only updates once a day.
5) Music app either Apollo or NexMusic great music players without equalizer. simple controls.
On an average day headed to work paying bills I see 10 to 12 hrs easy.
Busy day on my phone 8 to 10 hrs.
Turn off services you don't need or use.
WIFI - Turn it off when you leave your house and when you don't need it. Leaving it on will drain power as it will continue to scan for a connection.
GPS - Turn off your GPS if you don't need.
Sync - Sync when you need to. Turn it off and access it manually.
Bluetooth - Turn it off when you don't need it
Location services - Go to the Settings menu and head over to Location access and switch "Access to my location" to off.
Backup services - Head over "Backup & Reset" and uncheck "Back up my data".
Screen brightness - The lower the brightness, the more power you'll save.
Apps - Applications like facebook and Google Maps will remain online as it runs in the background. As a result it will drain your battery. It can prevent your phone from entering deep-sleep to preserve power.
Signal - Connection is very important. If you're in a area where service is low to poor, your phone will draw more power to stay connected to the nearest cell antenna/tower. It's best to turn off on connections if you're in a no service area. Simply put the phone in "Airplane mode".
Usage - Battery life is dependent to whatever tasks you are performing on your phone. If you play games daily for a long period of time, then you should expect the battery to decrease dramatically. Conversely, if you just email, text, browse the web, make calls, little to no games then your battery life of the phone should last for quite a long time.
Useful apps
Greenify - This application allows you to hibernate apps from starting up like facebook, Google Maps and many more annoying apps that run in the background when they shouldn't be running. https://play.google.com/store/apps/...GwsMSwxLDMsImNvbS5vYXNpc2ZlbmcuZ3JlZW5pZnkiXQ..
Wakelock Detector - This wonderful app identifies apps that running during your usage and sees which one has been running the longest without your consent. You can use this with Greenify. https://play.google.com/store/apps/...EsImNvbS51enVtYXBwcy53YWtlbG9ja2RldGVjdG9yIl0.
BetteryBatteryStats - Similar to wakelock detector but offers a more in-depth look of wakelocks that active during your usage. https://play.google.com/store/apps/...wiY29tLmFza3N2ZW4uYmV0dGVyYmF0dGVyeXN0YXRzIl0.
Kernels and roms
One major reason why root is amazing. Kernels offer tweaks that are beneficial for the phone to perform smoother and offer amazing battery life. Offers more tweaks as well like gamma and undervolting. Roms can contribute a small portion of battery saving but not much.
Did I miss anything else?
Adding Maps to Greenify usually helps a lot regarding battery life, can leave GPS on for other apps when doing this and won't suck any battery.
try franco or faux and then UV and UO ` its works for me, 4+ screen time easily :fingers-crossed:
I didnt expect so many comments! ive used franko kernel and air kernel before and no change
ill try some of them apps that everyone has mentioned
again thanks guys! Jack
Just use a ROM for a while, let the battery do some cycles, and use the phone for that, as a phone, remember that we have a Quad Core here, i'm on stock rooted only, and last night i get 12h20m37s with 4h48m SOT with about 7% left, so that's pretty good. And i really use my phone, Twitter, Flipboard, G+, Wifi on all the way, Sync on.

Yep definitely something's not right, facebook is known to be a battery drainer, i suggest to you that open it up on the browser and uninstall the app, try it!

With 80% left I have 1hr of screen on and 10mins of call time, this is with whatever kernel the latest CM nightly is using, so yeah you could definitely get better but I have to think facebook is the contributor since I too have twitter (plume) and tumblr without the same battery drain.
greenify is a must to disable rude apps which do thing without asking, like facebook, games, etc, they connect to internet to download ads and sttuff, facebook being the worse cpu eater
i use 2g only, wify in home, disable wifi outside,
only wassap active, some opera mini browsing, pics, talk, sms, little gaming, i get 1.5 days
off course heavy gaming kills the battery, because of 3d, even 2d games drain the battery because of the screen, like angry birds
using stock 422 + franco
I like to use JuiceDefender only when the phone's battery gets really low and I want to sacrifice some functionality. It works well, but only if you allow it to keep 3G/Wifi off when the screen is off.
I use facebook so much though, ugh :/ ill give it a go and if the battery lasts longer then ill get rid of it
single biggest difference I've seen is to stay on wifi all the time as much as possible. I leave it on no matter what. Granted if you are out and about, it won't help but once you get to home/work/friends/etc, your phone will immediately connect and start saving you juice.
91% after 8 hours with light usage at work. With 3G, I normally would be approaching 60-70% by now with light usage. That 3G drain is real and should be avoided whenever possible.
Don't play games. It seems like no matter what game I play, it'll almost always lock my cpu to the max frequency until I exit. Even really simple non graphics intense games.
Well ideally you're biggest battery drainer should be the the display. If it's not then read below.
1) So for the screen the best way to go is to get a stable custom rom like xenon and tinker with the auto brightness settings. Tweak out auto brightness settings to your liking (they're generally very overbright by default) and you'll see major increases in data.
2) Screen aside your other biggest drainer is cell radio. Particularly if you're in a low signal area it will drain your battery really fast. So if your using wifi anyway be sure to turn data off and switch to 2g. That way you'll have a strong signal and 2g drains less battery anyway.
3) As some people have mentioned already. rogue apps. Social networking apps are a huge drainer in this regard. Especially facebook. You just can't have that app on your phone and get decent battery. As for other apps which draw on unnecessary background data, Greenify their a**es.
