why is battery drain so different

hi
this is not question, just more a thought
now i have read on several post on different forum, about the battery drain on the galaxy s 2.
and my big "concern" is why is there sooooo big different on the battery drain. some people can last for 2-3 days and some only 5-8-10 hours. from what they are telling they are using the phone almost equally..
for an example this first post here, he still have 50 % left, although he saw video,playing , surfing and call http://forum.xda-developers.com/showthread.php?t=1055164
mine last for about 10-12 hour with moderate use.. and i have killed all unused apps/task/services, wifi ,only 3g, low brightness, wipe batt state.. and installed villainrom
it sounds to me that some people get a really good phone/battery and some not.

Everyone's idea of light, moderate and heavy use varies. It really only comes down to a few major things. How long the screen is on, how often the device is awake, and how intensively the device was operating while awake.

If people know what to do (search the bloody forums for a start)they can achieve good battery life, too many fools are too quick to come on here and complain about poor battery life without even searching the forum, also anyone who gets 2-3 days clearly isn't using the phone that much, i usually get a full day out of medium/heavy usage and you cant complain about that, this is a smartphone and if people are that obsessed with battery life i suggest they use an old Nokia

Very true. I can easily get 2-3 days if I just used it for calls and text.
Heck, I can get it to last 1-2 weeks. Just put it in flight mode and don't touch it except every couple of days to check %.
Why people don't just buy spare batteries is beyond me. I bought 3 spares + a wall charger off eBay for around $10. When I'm low I just pop the used one in the charger and replace with a full one. From 0% to 100% in 30 seconds. I even leave one in the car in case. Did the same thing with the S1.
BTW, to the OP why leave it on 3G? I'm assuming you switched off H. For me I use the 2g-3g widget and select GSM only. When I need 3g/H for data I turn it on.

My 2 cents
I will tell you this. For what its worth.
I've had 4 friends get the GS2. 2 of them are white, 2 are black (the phones, not them.)
In all four cases with the stock ROM They came and complained to me how they love the phone but the battery dies before they can get home.
All four cases I've done this update for them via ODIN
- ROM Update: XWKI4 (UK XEU, android 2.3.4 to support google video chat)
- Kernel: XWKJ3 (stock)
- Modem update: XXKG5
Each and everyone has told me they're getting literally exponentially better battery life, snappier response and stable usage.
Take it for what its worth. But i recommend your combo.
I think usage pattern is definitely important but i've experienced idle drain and gone through months of struggling with this. not all roms/kernels have the idle drain issue. The above combo should work well for you. Good luck

Well there are differences in software and usage, but thats it. use a clean up to date rom, good kernel and do not install crappy apps like facebook which drain the battery. Using a modem which suits your provider does make quiete a noticeable difference, especially with hspa activated, idle aswell as using the data connection. Battery life of 12 hours or less is clearly a use or apprelated problem.

2 years later?

I think this will be a good general discussion:
Whats the battery performance like for you guys on a 2 year old phone, i know after a while the battery begins to degrade which is why im trying to see if this is the case for everyone :laugh:
Also what rom, kernel, tweaks are you using to get your current battery

1.5 years ago I easily get 6-7 hours screen on with power saving mode, for now i only get 4-5 hours with the same usage with Hurricane rom.

this phone is not two years old......

Yeah this phone is not 2 years old yet.. but aside, I love the Note 2 and don't plan on upgrading. I have 6 batteries for it, plus a external charger, so I never have to plug my phone in again. As far as UI goes, yes, it's missing some features, especially on 4.1.2 (luckily I never did the update ), but its multitasking features are kick-ass. At least for beginners. I had to tweak things to my liking, thanks to Xposed, such as default expanded notifications, Multiwindow for all apps, and such, but now that I have so much time into tweaking this phone I have no reason to upgrade.

I hardly noticed any difference between the time I purchased and now. My phone is 18 months old now.
Then again it could b me using 2 batteries and rotating the battery between uses so it doesn't degrade that fast.
But then again I'm not on stock rom. I was using miui in the past. Then regret upgrading to 4.3 which I found it too big of a hassle to downgrade to use miui again (4.1) and used hurricane rom with note3 mod installed. I tried ditto kitkat beta and rc1 but always reverted back to hurricane after a day of usage.

Mine last fine, about 5 or 6 hours of screen on.
Kitkat official, about 30apps frozen (Samsung I hate you lol), and greenify ftw.

Im getting 4+ hours screen time with average 15+ hours minimum of use .
this is on 4.3 stock rooted and AGNi kernel set to extreme battery saver.
normally charge phone when still at 20%.
On stock 4.3 I was getting best 14 hours.

thats minimum because when playing clash of clans all day in a marathon to collect lute really kills battery. With norman use easy get 18+ hours easy.
I also de blotted my stock 4.3. Eitherway better battery than before.
cheers

I was stock rom and after numerous useless updates from samsung my battery wont last even 12 hours. I moved to xperized rom and even then battery backup was less. I have just switched to SuperBeam and I am seeing an improvement. will post detailed update later. right now getting near 14 hours with 3-4 hours screen time with wifi and bluetooth constantly on.

Hmm yeah thats what i get too here and there depends on if i play games or not which i rarely do! Im trying out Omega rom v27 4.4 atm and testing the battery for a couple of days :fingers-crossed:

really guys only 6-7 hours? I go at least 10-12 hours, yeah of course it depends how much you use it for example when I use 3G and Wifi Hotspot simultaneously the battery drains like 1 second for 1%. I recommend you guys to install WakeLock Detector app. This app will tell you which app drain your battery, and guys, remove the facebook app as soon as possible it was on the top of the list.

My battery life is steadily declining. Still getting by the day, but not easily like it previously was. Hopefully it'll last until the Note 4 hits.

Is there an app out there that can accurate measure the battery of your phone?

There are tons of battery app , there is one that comes with CleanMaster app hope that should be good as cleanmaster is good app

I get 2 hours and 30 min with screen on and 5 hours with the phone off the charger and on 3g and 2 hours with screen on and 4 hours on 4g with screen on with stock 4.3 and custom roms and i get 7 hours with the on wifi and 2 hours 30 min with the screen on that is with good signal and on Telstra.
Apps i am using are facebook and facebook messenger and pocket cast and google apps that is all on 3g
I've only had the Phone since 16th of January 2013 and that is with two battery as well

After 1 year 2 months of usage, my note 2 lives around 7 hours screen on for wifi and 5 hours screen on for 3G

Note3 8hr battery life

Note3 running Beans stock 4.2.2 rom. I've removed/disabled a lot of the system apps/bloatware and run a couple xposed mods (in pic below). Phone was half on wifi half on good 4G; also in good service areas entire time. GPS off, automatic brightness. I only get 4hrs of screen time and total running time is approx 8hrs with 15% left. I think this is quite low for a 3200mah battery. Anyone give me any suggestions to prolong the battery?..or reasons why I can't seem to go a full day?
...I posted this because my bro has stock nonrooted S5 with high brightness on whole day and can easily go 1.5 days with same on screen time so I was lil disappointed in my note.
Thanks ahead of time for any help!

you have something keeping the phone awake or chewing the battery...most note 3 get about 15-25 hours per charge... i keep my brightness fixed at about 25% i have greenify now it seemed to help.

How do I check what it is? I'm not sure what it could be but know that 15% with 8 hr total battery time and 4 hr screen time that it's a little under what I expect out of a note3.

solution to low battery life
It doesnt seem to be a problem since my old note 3 had the same battery life.
A tip ill give u is to try to turn off the wifi every while...
And also try to use this app: screen filter
It reduces battery life by lowering the brightness.

I have similar issues however I get a little better battery life as I have basically turned off every good option on this phone in order to make it last . Ive concluded that this phone has terrible battery life due to Android 4.3 and higher sucking up the battery unnecessarily .. the background processes are endless and truly destroy the daily longevity and options of this phone. Take a look at the Note 2, same battery, different operating system and more or less same hardware and out of the box the note 2 lasts WAY longer than the note 3 (at least from my own personal experience). Frankily, if it was possible, I would love to downgrade to 4.2 (or 4.1.x) to see how significant of a change the battery life would be. Thats my 2 cents

I use greenify and es task manager to disable auto starting programs. I see many more reports of other people getting 20 hours with 4 hours screen time.

that just adds more evidence to my theory... the android 4.3 OS is a battery sucking operating system when it doesn't really need to be.

I never had a problem with 4.3. I was running hyperdrive 4.3 with greenify, v6 supercharger, and a crap storm of other tweaks and xposed mods and with very little usage (didn't take a screenshot of screen on time) I was at 5 days 13 hours 43 min with 6% battery left. I tried to update to hyperdrive kit kat and had nothing but problems so I flashed stock nc2, upgraded to nc4 modem and have spent the last week (couple hours a night) modifying and tweaking. I'm currently at 1 day 20 hours 13 min with 4 hrs 15 min screen on time and I have 19% battery left. I would probably be closer to 25%-30+% but last night I decided to go all out with the cpu control and run antutu benchmark twice to test different I/o schedulers.

So do you think with a custom ROM instead of being on stock 4.2.2 will help me get more outta the battery?

Probably the first step would get better battery stats and find out what is draining your battery. Freezing app apps won't do much to save battery if your not freezing the ones draining battery. Also look into greenify you can hibernate apps that you need installed and to run frequently but can put them to sleep when you don't need them
Also I got rid of V6 and decided to do min free and kernel tweaks manually with Rom toolbox pro. Not sure if a fluke but currently I've had 2 hours of screen on time and only dropped 20%. That's as much a 10 hours screen on time on a single charge.

Did you flash to stick slot and flash nc2 before flashing hyperdrive or were your issues some menus did not work if so those have been patched and everything works now.

I had wakelocks that lagged my phone (500k+ in twelve hours) and ran the batter almost dead in that time. Yea I flashed nc2 upgraded to rsl8 and updated the modems. Just didn't feel like trouble shooting anymore and with xposed I can have everything I want and biting I don't

Horrible battery life on S3

Hello guys i have been facing absolutely horrible battery life on my s3 i9300 for the past 3 months or so....im currently running archidroid 2 which has absolutely amazing battery life as compared to the other roms that i have used and by that i mean almost all the popular roms that have been made for the s3 i9300 i have changed chargers....i just got a new battery about an hour ago and thats also not helping me at all i lose 2 percent in every 5 mins while doing light tasks like writing this thread and 2 percent in every 3 mins while playing games like clash of clans /fifa 14 ....one of my friends who has an s3 has abolutely amazing battery life he says he loses just 5 percent in one hour of fifa 14 i have disabled sync put my phone on 2g brightness on auto greenified almost all apps...pls help :'(

Yeah, those friends xD. On s3 you can play for about 3-4 hours depending on game. You must take care of screen on time. Look at it on yours friend phone Thats the real time of using your smartphone. Max screen on time that i had was about 5.5h but I was only reading a book. And the 3g browsing eats your battery like a boss I discharged my phone in 2h so thats normal.
Peace

Use BetterBatteryStats to have full control over it. Also, I don't know what apps you have running, but try to use Greenify.
You're running a custom rom, so the culprit can be the kernel too. Use an untouched stock kernel if you want or heavily tweak the custom one you're using.
We can't tell you more than this, because we don't know what you have installed, what you have running and how do you use it.

check out BetterBatteryStats, as already mentioned for the real battery killers.
put down the brightness to a low level
turn off your mobile internet in moments you dont really need it (i.e. during sports). just like you turn off wifi, when you leave your house

Is your phone 2 years old?
Buy a new battery.

try calibrate battery or boeffla kernel

Looks like your battery needs to be recalibrated.
Completely drained your battery & charge it for 8 hours without stopping during the night.
It happened to me too a few weeks ago when I bought a new battery.
Use BBS, greenify & tweaks your kernel settings will definitely help too.
Good luck

I still like the look of the S2

Replace your battery
Either get another Samsung battery - or go big and get ZeroLemon 7000mAh - worth every penny! and you get used to the size & weight pretty fast.

Awful battery life with any ROM/kernel

Hi, i've a i9505 and my battery life is awful, no matter wich kernel i'm using. I've already bought a new battery (RAV Power) but nothing changed. There's a way to check what causes those incredibile drain/a way to solve my problem? Right now, i lose up to 10% with a 15 minutes video on YouTube...

Search for Better Battery Stats on the forums and install it to check to see if you have a wakelock or other issue keeping your device awake.

Why is that drain? In general you only have battery drain when you lose lot's of battery while screen is off.
You screen uses power. Your cpu uses power. Your gpu uses power. 10% battery when watching 15 minutes on Youtube is perfectly normal.

Not when you've everything off except for Wi-Fi. Also, i'm always with just 15% of brightness and i locked all my cores to 1600 MHz, that's just not normal, my battery life was way better 3-4 months ago.

10% per 15 mins extrapolates to 100-0% in 150 mins. Which is 2 hours and 30 minutes of on-screen time. I'd say it's rather bad.
@Madafacca do you have a good signal reception? Bad signal can drain your battery a lot. I'm talking about carrier signal, not wi-fi signal.

I tried most of roms/kernel with my s4 and I can only dream of 2hours of screen on, even when it's stock, I use only viber, whatsapp and facebook ( without messenger ) and there is no way, i have 2 batteries, same with any of them... gonna add some money and buy lg g2, had it bout 4 months ago, and i get about 4hours of screen on time with g2, s4 for me is sh*t

Facebook is a resource hog. I haven't seen an app to use so much RAM as facebook does. And it also cripples the performance of the phone.

Everything is disabled in FB app, notifications, refresh, so when i exit it, it doesn't do any background refresh.... you can't say that is because of FB because I had like almost every phone until now ( except 2015 flagships ) and only s4 is so bad at battery, switched from s5 to s4 because I was broke and had to sell it, before s5 I had note 3, lg g2, m7, m8, z2, s4 active, note 2 ( 2nd best battery life after lg g2 )

Well, I don't know what's wrong with your phone. I can get 100-50% in about 2 hours gaming. I generally don't let it go under 50%. So that should mean about 4 hours total if I were to go 100-1%.

Battery calibration is a waste of time. All calibration does is wipe batterystats.bin, which is wiped when the device is fully charged anyway. Thus a waste of time.

I'm hating this phone right now, i think i'll switch to the 1+2 asap. Battery life is just too bad, i can't handle it.

Well, something is obviously draining your battery. 100-0% in 2 hours is just too much. In 2 hours I go from 100-50% when gaming. Of course, no wifi, lowest screen brightness, no bluetooth and no useless app's (like facebook app) running in the background thanks to greenify.
Put your phone in airplane mode and see how much drain you get. In airplane mode there should be practically no drain, since keeping the device connected to the network eats battery.

Yes there is but until we get some data from him we're basically tossing darts blindfolded. I recommended in post 2 that he install Better Battery Stats from the forums. If he runs it and posts its output, that should be of assistance in pinpointing where his battery drain is coming from.
OP, help us help you. Get the app, run it, and save a log of its data before your battery dies.
