My Galaxy S II (and pretty much any Android evice I've picked up) has a usable battery life of 45 minutes. I unplug the phone at 9 A.M. in the morning after charging it to 100%. By 12 in the afternoon I would have browsed the Internet, checked social apps and played a few rounds of a game for what feels like 45 minutes in total. By then the battery is at 30% and I have to put it away in fear of it dying before I get home. The phone is useless for the rest of the day. My iPhone 4 with its 3 year old battery lasts 2 days like this.
No wakelocks, 99% deep sleep. I have a 3200mAh battery which feels like it lasts 1.5 hours before I have to put it away in fear. Basically the phone is not usable at all due to the user being in constant fear of the battery dying.
If I don't use the phone at all it's down to 20% by the end of the day with no wakelocks and 99% deep sleep. If I don't use my iPhone 4 with its 3 year old battery, it still lasts 20 days.

Well, or you buy a new battery for the S2 or you keep going with your "stylish" i phone. The world is not complicated and phones are not rocket science.
And by the way, games drain battery hard, very hard.
Charge at work, upgrade the battery or stick with your iPhone.
I tip my hat to you and wish you a good day.

I hope you checked with BBS, if so and as you said "99% of deep sleep", it means that the games are draining your battery.Well, sometimes even a "newish" battery can be faulty.Try with different battery,I mean a good one for sure.And if your results are the same, stop playing those freakin' games.

Yes I use BBS and have completely disabled all bloatware using Autostarts. I have the original battery and the Mugen Power 3200mAh battery. The battery life is proportional to with the capacity of the batteries I've used.
The primary use of my phone is mobile gaming. I don't care about the phone part except for receiving push notifications for email, IMs etc. which I then reply to on the PC anyway.
My SG2 and pretty much every Android device I pick up has 45 minutes of battery... Either you have won the lottery and got a defect phone several times or there is something fishy going on..
My sg3 lasted for 24 hours, my s4 last for a couple of days, my motorola razr lasted a week and my iphone 4 went for a day and sometimes 24 hours..
Even if I stress test my sg4 and s3 all the time it would last for a lot loooonger than 45 minutes..
I know the games will use a lot of juice but 45 minutes? Something is wrong...
What kind of games are we talking about? I do not play so much myself, just online poker, some tetris and so on, my iphone and android phones is pretty similar when talking about these games...
You could go for a Nintendo Game Boy etc
That said I taught ICS used less battery than JB. And it's pretty weird if you have the mugen battery. My Razer had a 3300 battery and that would go for days, even with heavy usage.

I've extensively used the Galaxy S, Galaxy S II, Galaxy Note, Nexus One, Nexus S. All of them can be used heavily (3G, gaming) for just 45-60 minutes before the battery is low and you have to save it for the rest of the day.
Simply listening to music for 2 hours in the gym drains 35% battery! WTF? This is without any equaliser and while using an external headphone amplifier. I could listen to music for 2-3 hours a day for 1 week on my old iPod touch before needing to charge it.

With zero usage and I mean barely switching on the screen once or twice to check the time, my 3200mAh Mugen battery is at 55% by evening. No wakelock, full deep sleep. The original battery will be below 20% or dead with zero usage.

Possibly a crap battery, but im going to suggest you don't use the samsung charger. The phone holds a wakelock whilst charging, keeping the phone running at 200Mhz, so unless you are delivering 650mA, your phone will die. Therefore I suggest you are using an unofficial charger, which doesn't deliver the needed 650mA, or you have an unofficial battery which wont accept 650mA. Either way, if you're not using Samsung appliances you shouldn't really be complaining about crap battery.

I am using the original Samsung charger and the original Samsung battery. I have an additional 3200mAh Mugen Power battery.
It drains faster than the charge rate only if I'm playing games.
Could be many things then, but as you say BBS doesnt report wakelocks, it would all just be conjecture. Try and pull a logcat after an hour or so of deepsleep and see if you notice anything untoward. Also, have you done simple things like turn WiFi off when you're not using it? That scans every 15 seconds or something. Or if you're in a crap phone signal area, your phone will keep scanning for and trying to connect to a better signal.

It's the phone obviously. Like I said if I put it in Aeroplane mode than the battery is still at 99% at the end of the day. If it's in normal mode it drains severely. I don't have this problem on any other phone. I've flashed the latest modem for my region and tried older modems for my region as well.
Not sure but it sounds like you have technical issues with your phone.
I have the official Samsung uprated battery and I loose about 60% out of the phone battery a day with heavy usage. Usually doesn't get to that point as I charge at work or home when not in use.
I take it as a given that all smart phones, tablets or laptops have ****e battery life.
Blanket generalisations about specific OS' or brands being superior to others is just silliness.
Saying that, when it comes to battery life, my HP Touchpad running CM 10.1 pisses all over any iOS device and the ghost of Steve Jobs agrees with me!

60% at the end of the day is a joke. It's unacceptable. Without use My iPhone 4 is at 95% at the end of the day with everything switched on and every possible syncing enabled. Why is it so hard for Samsung to produce a properly working phone after 5 years? I am 100% sure their latest phones like the Galaxy S 4 behave exactly the same way no matter what PR bull**** they try to spin.

Seems the iPhone is the device meant for you, for me in normal usage it lasts 2 and a half days altogether with the stock battery, heavy usage like a gameplay of Gamelofts Modern Combat series or N.O.V.A gives me 3 hours of continuous play after which the battery reaches around 7-10%, wifi in JB sadly kills my battery only gets around 6 hour's with continuous usage which was greater in my GB and ICS days.
But 95% at the end of the day for the iPhone 4 with everything ON is a bit of an exaggeration(the hell kind of unremovable battery is that?) don't you think?

Hi,
What is the battery life we may expect from a Galaxy S2 ? Mine (from fully charged) lasted only 3-4 hours surfing the web using 3G, maybe including some wifi usage, however screen was dimmed down. Isn't the battery supposed to last a little longer ? The phone is new and I am on the third day now. Is there anything wrong with my device or will battery performance improve after some battery cycles ?

Mate 3g browsing on the sgs2 does kill that battery in 3-4 hours max.. that is actually the time scale most reviews give.. i know its a pain i hate it myself, but ull find generally using the phone ie camera, music etc gives you a longer battery. The browser rocks! but its a serious power drinker, i did discover that some sites are saying that using a 3rd party browser helps things abit e.g dolphin or opera. It has something to do wiv the gpu accelaration which enables u to do things like play 1080p videos in the stock browser and the constant smooth perfomance
oh and i found the battery does improve after a few cycles, but i think thats mainly due to the fact u tend to not be constantly playing with the phone al the time
Yep, 4 hours tops for me screen on usage.
Using Juice Defender which helps a bit..
Abouth the battery...
Earlier this evening my phone was at 28%, when i picked it back up an hour later it was 31%????
I watched the battery graph and it showed a Yellow line going upwarts slitghtly., is that strange??
Afterwards i saw green going down and than up again. I will post a pic of it.
Seriously, there are 5+ battery threads already, what is so specific about your case you felt the need to start a completely new discussion on it????
Fully charged this morning, moderate use throughout the day, on 52% now after 16 hours. I'm happy with that.

if they made the phone a bit thicker a tiny bit they could of put a bigger battery in there but samsung wants to compete with apple on thinest phones.

If it's notbthe stock charger you areblikely not using a rapid charger.

I pull mine off the charger at 7:00 and at 3pm or so it's down to 85%, I'll put it on the charger at work until I leave around 5-6pm (mainly because I'm used to having to do this on my previous phone) and at night if I'm not using it constantly it's around 70-75% when I plug it in at bed time.
I suspect anyone getting that bad of battery life must be using it constantly, ie: Playing games, browsing, trolling facebook, etc.. Even in the "new toy" stage I'm getting great battery life.
FYI I don't have LTE, but do generally have good 4G.
You honestly can't use any phone on GPS without external power and expect that you're not going to discharge quickly. Assuming that you are running a car charger during GPS and just didn't say so, search the i-717 threads, since the topic has been well vetted on what chargers are more effective,etc. There are definite differences.

The fact that there are people out there that get really good battery life means the problem is you and not the phone. If you refresh facebook every minute of course your battery life will be crappy. apps like juicedefender are just marketing crap. as long as there are no running apps in the background that eat your battery, you do not need any juicedefender or tasker. also setting screen-off behavior to conservative on set cpu helps improve battery life.
When I first got my i717 and was using it on the stock rom I had pretty terrible battery life. I take it off the charger at 5:00am and had decent battery life (around 5 to 7 hours without GPS) but I use my phone a lot for internet/email. I think your battery life is completely normal given your usage.

I had GPS running on my phone for 4 hours today, had blue tooth on half the time without knowing it, sending text messages, making two 5 min phone calls, checking maps, checking FML and reading a book for about an hour and drained down to about 70% and I have the brightness set at auto. I would exchange it for a new battery.
On average with several texts per hour, several 5-10 min phone calls, taking a few pics and uploading them to picasa, checking facebook, updating status and checking emails I can pull off the charger at 630am and still have 50% battery (at least) by 630pm.
I do have the juicedefender (which isn't crap, it turns off signal after so long so you aren't trolling for signals when you aren't on the phone).

I had a ss of my buddies yesterday, but can't restore mms lol. There are plenty of other ss in the note section. He was at 22+ hrs with about 4:30 of screen on and some % remaining. I have to charge around 7-9 everynight at 4-4:30 hrs screen on, but my use is pretty heavy. I sync 4 gmail accounts, a separate GV, 3 calendars, and several apps.
If yours is much worse than that, you likely have a few troublesome apps or are playing games. First, after a full charge, reset cpuspy timers, lock it, and set it down for a few hours (I know, impossible). Then check to see that your CPU has been in deep sleep about 95% of the time. If not, use better battery stats to see what has been request wakelocks. Not only the most total time, but the total number. Any app that looks outrageous, freeze it or uninstall it. For system processes that look troublesome, Google. You can often find simple tricks online that will tell you what's causing them to go crazy. Beyond that, turn off syncing of anything that isn't needed or doesn't matter (like Facebook), and uninstall stuff you never use.
Another slight help is the brightness widget (don't use the actual widget, just put the app on your homescreen, it works the same) or dimmer in market as they can both set the brightness to a value of 10 (Samsung lowest stock is 20), and even if you can't tell the difference, it helps. Jkay settings in saurom can set the auto brightness profile slightly darker than stock. Umm, and the obvious, use less Widgets, longer sync intervals, processor scaling and speed profiles, and buy a couple rapid chargers, wall and auto.
A couple things to note after seeing a few of these posts...
BT can be on, but without it searching, connected, or listening it's not active.
GPS isn't active unless its in use aand you see the icon in the notification bar. That being said, fb, websites, and many other apps that request location will activate it.

YOU MUST CALIBERATE THE BATTERY!! I have no issues I use my phone heavy all day and get 15 hours and I still have 20% left. All you have to do is
1) Charge you phone until it says "charged"
2)Leave phone plugged in and power off and let it charge until the battery meter literally says "100" (screen will sleep so you can check with volume rocker to light screen)
3) power on phone and let boot and than power off and wait till you see 100% again
4) now keep doin this and you will notice it will start displaying "100%" faster and faster usually takes 6-7 times cycling like this
5) After you do this download Battery Caliberation (root required) app from market and hit the caliberate button and boom your good to go
I do this on every android phone I own when I flash a new rom or purchase a fresh one. Everyone should do this everytime you flash a new rom and I can CONFIRM significant battery longevity on all my android phones I have done this with
You only have to do it once so just get it out the way and you'll get through a whole dayand have some juice to play with.

Just to be clear here, Tasker has nothing to do with battery life. It doesn't hurt it, nor "help" it. However, you certainly could write tasks/contexts that would decrease battery life, and there are a few scripts out there which do silly stuff like autokilling, etc... But if we're talking "battery savings", Tasker and JD do not go in the same category.
IMO JD is only useful if you're frequently in an area with no signal, like you work in a basement or deep inside of a solidly constructed building. Since you mentioned Tasker, in this context it does help me a bit on battery because my wifi turns off when I leave the house, but that's also something JD can help with. If you don't have a wifi connection it'll turn off wifi (and I believe turn it back on periodically to see if there's one available?) I don't use JD, so can't speak too much for it.

I'm going on 17 and a half hours with 73% battery left. Not a ton of on screen time but a lot of deep sleep but still good to me

The biggest drain is the screen, while in use, and this is my suggestion. Definitely has increased my screen-on time.

I use my note running Saurom RC7.1 with overclocking from 5am until 11pm everyday, I am doing various tasks throughout and have alot going on with different widgets running and such...
5am = 100%
10:15am = 73%
Not sure what your doing but maybe your battery maybe not holding a charge like it should?
Eric
Do not use Hyperion, QCell or any other cheap ebay/amazon batteries. They are only about 1700mah at best and will kill your phone under moderate use in about 60 to 90 minutes. Maybe less.
I'm on stock GB rooted with all bloat frozen via TB and I can get through a whole day of use on one Samsung OEM batt with light to med usage.

This is no where near the average!
And you seriously must not use your phone, like at all
17 hours at 73% is a bit extreme, but so is 2% per minute drain.
I think I can represent a fairly average user. I usually check email, weather and a little reddit during my morning routine. BT is always on and connects to my car while I drive to work for about 30 minutes. I average about 2 or 3 long phone calls a day on my phone. Some text messaging throughout the day and some short internet sessions on my phone while at work. Plus a few minutes here or there for Draw Something. I stream Google Music every day on my way home for about 30 minutes. Once at home my usage varies depending on what I do for the evening. But so far I usually find I have about 50% battery life when going to bed. I actually made it through Friday and Saturday on a single charge.
So I would say that this phone has above average battery life for an android device. It isn't stellar, but it isn't bad either. My Infuse could eek out about the same life with less use. My N1 never made it even close to this length. My buddy's MyTouch 4g can't usually make it a full 24 hours.

Considering the screen size, the battery isn't actually that big. It sounds enormous due to other phones with almost a thousand less mAH, but I just bought a bunch of extra batteries. The removable battery feature is the biggest reason I switched to Android.
LTE is a HUGE battery killer. I turned off wireless since LTE is SOOOOOO much faster than any wireless connection I'm on. I'd be lucky if I could get through a workday without it being below 50% by the end of a work day and completely dead by 7pm.
Turn on wireless and it's now almost 3pm and still have 78% left.
Lets face one fact everyone is different. .everyone claims this and that and regardless of what carrier or what device people will.never see the batt life they would really.like to see.Say like 50% after 3 days heavy usage that would be a thing we.may see in.smartphones in a few years. Android o.s will always be battery harsh.Its a huge topic.
Another point.on all the claims of Great and terrible batt life has to do with the fact. .people just dont truly get how others may use there devices so heavily..streaming vid...music...downloads...mail sync...Some maybe few truly use there phones 24 hrs non stop. There probably will never be a batt drain solution for those people.So telling one person that batt is fine with all this moderate usage coming from a person who uses there data more like "lightly" rather than heavy, doesnt help a person who is a heavy heavy data user.Neither sides will ever come to an agreement.

best thing to do... use setcpu or some other overclock program. make a profile so that when your phone is sleeping it runs at the very minimum. my battery can last me up to two days depending on use. heavy use at the very least 7 hours
This is about how much screen time I get a day with the new collective ics rom

Wow that is awesome! I'm getting home with a full days use at around 50-60%- It seems to be better than my captivate was on life that's for sure.
I have had mine for two weeks- On side note? hehehe Does cycling a battery really prove to get better life as time goes by or is it a old school story about batteries use to have memory etc... and now they don't?
Modern batteries don't have memory but their battery meters can become decalibrated which can be fixed with a full change cycle. Nonetheless, I don't recommend doing that too often (I only do it like once a year) since that's bad for the battery.

I've heard several different opinions on this. Condition or not to Condition the battery.
Do we need to condition this thing?
How are you doing it?
What kind of results are you getting?
Thanks in advance.

Li-ion
The battery is lithium Ion so you really shouldn't have to from my understanding.
People do even tho is not necessary, for some reason I don't but after a few day battery has gotten better

I mentioned this earlier -- I know it's a li ion that shouldn't need conditioning but when I first got mine my battery life was absolutely horrible. I went through two full discharge/recharge cycles and it seems to be much better now.
Currently 11 hours on battery, 50 minutes screen on, played a couple of games, downloaded a couple of apps, 15 minutes of voice calls, and battery is at 80%.
The way it was when I first got it, I'd probably be at 40 or 50% right now, if not even lower.
I'm also running juice defender and have stopped using the gmail app because you can't set the sync interval on it. Instead I've been using the built in email app and have it set to sync every 30 minutes. Not sure if any of this is doing anything but my battery life is definitely better than when I first got the phone. At first it was so bad that I came very close to just returning the phone.

That's true for me as well now that you mentioned it. First day, I got about 4 1/2 hours with it before i was down to 10%. I was shocked! Each day it has gotten a little better. Over the last 36 hours it has last a full days before a charge. It doesn't really make much sense to me that they are li-ion which shouldn't need conditioned but it seems that we do need to do this. A friend suggested I condition it when I got it and before I started heavily using it, I guess he was right.
Li-ion batteries don't need conditioned. Any signs of conditioning you see may be some sort of conditioning/learning of the OS.

See this kinda stuff freaks me out. I had one decent charge so far, had the phone a week, have been doing full discharge/charge the whole time. Sitting at 38% right now on 16 hours, about half of that was asleep with power save on (its been dropping 20-30% overnight) and only 48 minutes screen time. I dunno how long it should take to improve but it seems like its not taking this long for anyone else.

How long do you usually sleep for???
Seriously though, 20 - 30% overnight sounds like a lot. I tested mine and it dropped about 8% in roughly 7 hours of zero use while I was sleeping. I think even that is a little excessive but I can live with it.
Have you tried running something like Juice Defender? It seems to have made a difference with mine. When I got my S3 last week it was about the same as yours. I did a couple of complete discharge/charge cycles, installed juice defender, and have been going into the task manager and app manager and turning off all the crap that doesn't turn off automatically. It has made a difference.
Oh, and I also did the APN trick to disable LTE. Not sure if that has made any difference but with everything combined the battery seems to be doing a lot better than it was at first.
Don't "they" say that you should not use task managers as they don't work well with the phones? I'm no expert here, so don't quote me, but my understanding is that the One S and Siii owe a lot of their excellent battery lives to their own internal task managing.
Correct me if I'm wrong here.

The internal task managing is the reason you shouldn't use 3rd part task managers. That's the whole point. Android has done this since 2.0
Having said that, there's nothing inherently wrong with killing a task that is misbehaving... most things that say not to use task managers really mean to not (a) turn on auto task-killing, or (b) kill tasks across the board, albeit manually, under the false impression that freeing up RAM is a good thing.
When you guys say full discharge do you mean draining the battery till it shuts off or going down to 10%, I was under the impression that fully discharging would harm the battery.

I discharged it till zero. Then I turned the phone on and let it shut off again. I did this until the phone wouldn't even try to turn on any more.

Doing this enough times has the potential to damage your battery. Leaving it at 2% - 5% will not make a difference in the "calibration" compared to completely killing the battery.
Killing the battery may work for you, but I want others to be aware of the potential of damaging the battery.
Just my 2cents for the day.
Here. Is a link to battery charging for Li-ion. I have another site that is great in explaining these things. I have a couple of R/C trucks and this info is great to know and have. The same applies. To our phones charge rates. I would hope that when a dev makes up or mods a kernel that they have a basic knowledge of charge rates and the rest of the equations. Foe our batteries this is literally. Life and death. It could also cause a phone to burst into flames. Especially. If we use after market batteries that have poor protection circuitry in them.
I will find the other link later and post it up here to give a possible better understanding of these things. But, try not to rely on me as I tend to forget things a lot. Car accidents will do that to you when you crush your skull. Any way, GIYF.

You basically only need to do the "calibration" once. And the phone has limits set that will neither undercharge nor overcharge them.
edit I think heat is your batteries worst enemy.

This is the WORST thing you can do to a Li-Ion battery. I mean literally you can lose 10% of its life from doing this or even cause the battery to stop charging at all.
http://batteryuniversity.com/learn/article/charging_lithium_ion_batteries
Li-ion should never be discharged too low, and there are several safeguards to prevent this from happening. The equipment cuts off when the battery discharges to about 3.0V/cell, stopping the current flow. If the discharge continues to about 2.70V/cell or lower, the battery’s protection circuit puts the battery into a sleep mode. This renders the pack unserviceable and a recharge with most chargers is not possible. To prevent a battery from falling asleep, apply a partial charge before a long storage period.

Seriously everyone should spend a couple hours on that site at some point. Half the information will probably be way over your head (or at least it was mine) but there's enough good information that even half of it is definitely worth learning.
Here is the other site that I was talking about. Though it is for R/C battery packs it should still grant a measure of understanding to the workings of these batteries.

Take into account though. These batteries have circuitry. Built into them to prevent you from truly discharging. It all the way. That doesn't mean that it can not discharge all the way. Things like humidity can play its roll in taking a Li-ion or Lipo battery past the kill zone point. If you know that you will not be using the battery for a good period of time or it is strictly an in case of an emergency battery. Place it into a plastic bag and suck out all of the air that you can and seal it. A zip lock bag works best. Place it in the refrigerator or freezer. There is very little moisture. In there. And what ever moisture makes its way in when you open the fridge. Or freezer will not have time to get into the zip lock bag. The lack of moisture slows the discharge process down especially in the summer. Also the chilling of the battery's chemical. Compounds slows the molecular interactions down. Its a helpful two fold process.

How is the battery life on everyone's LG V10 VS990? I've got two batteries, a 3000mAH and a 3800mAH battery, but I find the battery life seems poor on either battery, both only lasting about 6-8 hours, sometimes a bit longer if I'm not using my phone a lot that day. Is this just me or everyone? I know a friend of mine with the T-Mobile variant of the V10 gets almost two days of battery life, but I'm not sure how heavy of a user he is.
A non power user can make a battery last forever on this thing. Weekends, I am not tethering or running Pandora, or getting blown up with group texts, so I can unplug at 8 am, and plug it in at 11pm with 30% or more. Week days, with all those things going on I can just get through the workday from 7:30am to 8pm or so and have to plug it in asap.

See, I unplug at 7:30am and can only get to about 3pm before I need to swap batteries if I'm not careful about how much I use my phone. Though I do a lot with my phone, it doesn't sound like as much as you do. I've checked the battery usage and it always says the Screen and Android System are using the most battery, which seems to be normal on most phones, so I know it's not a particular app. These two batteries are also only about a month old.
Don't know, I got mine at release, I do have two batteries, but only carry one unless I travel out of town. I often click to close all apps often throughout the day and use Wifi whenever possible and whenever not tethering to my iPad.
After root, I get roughly 2 days on a full charge. Greenify and freezing apps has increased battery life dramatically

Verizon location services app eats battery at a crazy rate even when the phone is asleep. Now when phone is sleeping it eats about 1% per hour instead of the nearly 10% it was eating. The stock battery is small to. 2800MaH for a phone this size is not a lot. GPS also eats battery. If you have location on try turning it off. Also if you live on the edge of a cell zone and your phone has to constantly keep talking to the tower it can use a lot of battery. You can test this by putting your phone into airplane mode, if your battery suddenly gets better... then the cell radio is killing you... unfortunately not much you can do for that.
I haven't been using the second battery yet, keeping it around as a replacement because we know what happens after the first year of using them.
