Just right now i'm on a bus and lost 5% in less than 10 minutes. Listening to music. All i did was send five texts, check Facebook for a minute and read the posts on this thread. That doesn't seem normal at all. 4G on, sync on.

this is more than what I'm expecting, but definitely shows that something is wrong with my battery life.
[T-Mobile Samsung Galaxy S II SGH-T989] xFrozen:
You give me some hope. I recently ordered an Anker 2050mAh battery for this, hopefully that will help in the meanwhile.
[T-Mobile Samsung Galaxy S II SGH-T989] doug36:
2050mAh wouldn't get you to much more out of thr battery..

Only 200mAh over stock, hows this supposed to help if you have a sleep mode issue or app issue?

Bringz me back to my first statement.

Your kernel is NOT allowing deep sleep mode for whatever reason, your best bet would be make a backup

Delete data/factory reset and try it over a day.. if it works good, its an app issue, still the same. It is undoubtedly the kernel. Why pay more for maybe an hour out of your phone?

Run some actual tests to clarify the issue first..

There. I said my peace
[T-Mobile Samsung Galaxy S II SGH-T989] RealPariah:
If you tried everything else try recalibrating the battery.

I have seen this happen most often when flashing new ROMs. Especially if you did not wipe your system, data, and caches before install it seems to encourage this.

To	Recalibrate Battery (must have custom recovery like cwm):

Charge phone to FULL

(I highly recommend AC charger for this)

Reboot into recovery

Look for wipe battery stats (should be I'm advanced if not main menu)

Unplug phone and restart it

Now FULLY KILL THE BATTERY

(for faster results set mp3 or video on repeat and let her rip)

Fully charge one more time and done

(again I highly suggest AC adaptor)

Keep in mind if you set your CPU to Max frequency or leave a demanding app running and CPU is set to allow full usage ondemand or performance the phone will kill battery very quickly.

Same if you leave antenna on auto 4G and it is weak around you and phone is always searching it will go fast as well.

xFrozen: have you downloaded cpuspy to actually see if your phone is hitting deep sleep?
[T-Mobile Samsung Galaxy S II SGH-T989] doug36:
You sir, are a n00b, calibrating the battery is useless to this device and actually done automaticly.

So your post is useless and rather a waste of everyones time even reading. So thanks.

@above

Its obviously not hitting deep sleep, there's no way it can be and be draining the battery this quick.

@OP

As suggested above use cpuspy to check on the cpu when idle,

Sleep mode should kick in within 30sec to a minute.

Also chek my reply a few posts up and follow steps there..

Ignore Realn00b's post

Again:

@Realn00b

Please take the time to read up on batterystats.bin and find out what its for,

You don't need cwm to delete, just root explorer.. its in:

Data/system/batterystats.bin

Also, the entire basis of this is stupidity and was takin way out of context.

Batterystats is used to cache the active information of running applications (uptime/cpu usage, etc. NOT battery percents)

And should only be deleted under very very rare occasions (effecting above)

Your battery percent, is actually the mAh

Your system collects the information from a chip on the battery, among the information read, max mAh and current mAh.

The device then calculates from these the value we know as the percent.

Meaning, no device with a lithium ion battery stores charge information for the battery, making the entire purpose of your post for this, or ANY device not only useless, but also a little pathetic considering you would actually try to post a tip on something you are obviously completely uneducated about.

Please don't provide tips unless you are 100% sure of the situation and are actually educated on the material. Thanks
[T-Mobile Samsung Galaxy S II SGH-T989] xFrozen:
I originally purchased it for two reasons:

1. For long trips or for when I'll be gaming a lot

2. It had no reviews, so I figured I should buy it and test it. It's cheap anyways, $11.

Also, I'm on stock kernel. Everything stock + rooted.

I just did a re-flash with ODIN, so it has all the bloatware back on. I rooted and installed most of the main apps I use (facebook, aim, xda, google apps, games, basic things).

Currently I have sync on for Google contacts, calendar, and gmail. Facebook syncs with existing google contacts. T-Mobile contact sync off. Dropbox auto uploads camera photos on wifi only (I rarely take photos).

It's charging right now, at 50%. I might not have time to leave it idle today, so I could try in the morning if I have time.
[T-Mobile Samsung Galaxy S II SGH-T989] doug36:
Yea your right that is a good price.. is it same size as stock and have NFC? can you post link?

Thanks.

And please excuse realn00b up there..

He didn't know wat he was talking about.. read my post below it if you want an explanation.

Take a look at the safe to remove apps list aswell I'll see if I can find it on google pages for you. I definitely recommend

Deleting unndeeded applications and even replace stock with third party where applicable.

[T-Mobile Samsung Galaxy S II SGH-T989] doug36:

That is a good deal.. doesn't say if it has NFC though, got some tags comming now

So definitely want that lol xD i dont want one of those bulky ass ones though
[T-Mobile Samsung Galaxy S II SGH-T989] xFrozen:
I don't think it has NFC since it's not stated, and I don't mind not having it. I never used it and probably won't for a long time.

I have high hopes for this battery. I got an Anker battery for my HTC Sensation (stock 1500, Anker 1900!) and it was AMAZING. It felt close to 1.5x - 2x the battery life, yet only a 400mAh difference.

The best thing is, it fits with the standard cover, perfectly :)
[T-Mobile Samsung Galaxy S II SGH-T989] doug36:
Nice.. and ye.. aslong as I had the stock doesn't hurt to have a spare I guess

Thanks again for the link bro, much appreciated

And sorry for having to try and make that clear for him back there and kinda throwing the post off lmao xD some things just need to be laid out in black and white for people..

*edit when you get em lemme know how u like em, might buy em, but I like my reviews xD

Also:

heres that list

Found it right here in the forums actually xD thanks noodles2224

Whoa. That spreedsheet contains golden information. Is it certainly for SGS2 or for other phones too?
[T-Mobile Samsung Galaxy S II SGH-T989] suaverc118:
What does sleep mode mean? I am not rooted and my phone will be around 20% around 6pm or so and has been uncharged since 8:30 or so. So i was wondering when my phone turns off (not powered off), what can I do to get more battery life? Again, what is sleep mode?
[T-Mobile Samsung Galaxy S II SGH-T989] xFrozen:
Sleep mode is basically what happens when you lock your phone. The display goes off and once any running activities are done, the phone just stays idle, doing nothing but waiting for calls, texts, or background data.
[T-Mobile Samsung Galaxy S II SGH-T989] doug36:
Precisely,

Your phone has two sleep modes,

we'll refer to them as Standard, and deep,

Standard happens as soon as the display is turned off, either by timeout or by pressig power/locking screen.

This process cuts your cpu speed back a little bit, aswell as obviously, turning off the display, etc.

The second, deep sleep comes approximately 30seconds to 1minute later, where your wireless is usually timed out,

Cpu speed cut, programs resources cut. Connections dimmed. This proccess is the most energy efficient of .

the second mode CAN be disabled on applications request, say your downloading a large file and the display turns off,

Deep sleep wont initiate till the files done.

And to get more juice, read posts like these, their all over the forum

*edit|21/03/12

@xFrozen i think it is.. lmao xD

That spreadsheet is awesome, and i think its for the SII/s2x family as some on the list coexist with other phones (i9100 has some)

And there is some that might not pertain to this device persay..

Forgot to answer your question and didnt wanna make a new post to do it xD
[T-Mobile Samsung Galaxy S II SGH-T989] FrancisV:
To help clarify a beleaguered point.

All lithium ion batteries have a monitoring chip in them since the lithium ion batteries, unlike their NiCad counterparts, have a nasty habit of burning up if overcharged. Anyone remember the counterfeit Dell battery fiasco a few years back. Android can query the charge level but the built in the charging circuit does all of the actual monitoring and control . If Android had anything to do with the charging of the phone how could you charge the battery with the phone off!

As for calculating the true discharged level, it's based on monitoring current over time calculating the presumed level. In other words it doesn't directly measure the charge level, instead it keeps track of the input and output over time, and uses that, coupled with it's knowledge of the battery pack's capacity, to provide you with your current battery level.

In theory totally draining your battery (which is actually not totally drained since that kills a lithium ion battery so the battery monitor prevents it) does set the battery to a known level allowing monitoring to be re-baseline, and but I doubt this makes a huge difference. Personally I don't do anything special to my batteries. I simply trust the phone to monitor the battery for me. On occasion I'll accidentally run the phone dead through stupidity or circumstance, so I don't run it dead on purpose. As far as any apps that claim to condition batteries, well they smell like snake oil to me. And constantly running your batteries to zero isn't being very nice to them either.

For those who remember the days of the NiCad, you'll likely remember how they would develop a 'memory' if you didn't run them dead each time you used them. Lithium ion batteries do not develop a memory like the NiCad did. Lithium ion batteries don't mind being topped off. My philosophy is plug in and plug in often.

Now for a question? I normally get great 4g coverage. However I work in a huge metal building. While at work I have Tasker turn off 4g for 50 minutes of every hour to save battery life. I definitely see a difference in battery life when I use Tasker to switch off 4g. For example if I go to an area in the building with barely enough coverage to keep the 3g/4g alive(my building has many such areas) my battery will be dead in two hours. That's with zero actual use! Same use case but now in an area with a strong 4g signal and I might drop 2 to 3 percent an hourly My question is, I am assuming the radios are somewhat independent from the Android OS. Short of turning the 3g/4g off like I do now is there something else I can do to trigger a timeout that will make the radio give up trying to communicate with the network? Just curious, my Tasker knock off of juice defender is working fine.
[T-Mobile Samsung Galaxy S II SGH-T989] Teo032:
Your phone is being drained by an app or something in the background. Your screenshots shows that something is still active when your phone is suppose to be asleep. I would factory reset the phone and you'll be fine.
[T-Mobile Samsung Galaxy S II SGH-T989] doug36:
Sorry, just re-reclarification xD

It must be said

(At least you use commen sence

1.) Lithium ion cells have a control board with a chip

This chip has multiple strings of data, some variable, included in this data are:

Max, min, and current mAh, max is listed on the cell casing, min is usually round ~100mAh, current, is obvious..

Once said cell is connected to a device that device is automaticly given read access to this chip.

The chip, if current value >min device is given enough current to initialize.

2.) If current mAh is equal to, or lower than said min, device is denied privileges.

To put it simply:

The battery gets all "nooooo its mine, you no touchy"

dropping ths cell to 0mAh will reset the board and drasticly reduce expectancy and overall life of the cell.

3.) This works the other way to:

When MAX mAh meets current mAh, said device drops connection to rhe cell and resumes strictly on AC.

4.) said device has NO write access to this chip, making theories on overcharging, draining, charging from half, using different chargers (read one of my other posts for clarification on chargers), modifyin a file on said device,

On this or ANY device with a lithium ion cell, IMPOSSIBLE, and rather born of stupidity. Honestly people need to research more..

to answer your auestion, this isnt from a timeout, basicly your datas constantly connected, when low, the device then trys to increase intervals to make up for loss of quality you can disable, lemme see where i seen those timings..

I don't really know why but I don't really like launchers, for example nova.
[HTC Sensation] dallashigh:
The launcher that comes stock is part of Sense. When a chef removes Sense from their ROM the launcher is removed, so they have to replace it with a different launcher. If you can't find a third-party launcher that you like, you'll have to stick with Sense ROMs.
[HTC Sensation] lccl97:
Aren't there some phones that do not have any Sense or TouchWiz or anything like that? Just a stock GB or stock ICS without any extra launcher or modifications by the maker of the phone?

I think that the answer to your question would be alomst universally no. If there is an android phone it has a launcher, same with all other phones pretty much. Check this out http://xdaforums.com/showthread.php?t=1545845

U r better off with some kind of launcher anyways
[HTC Sensation] KAwAtA:
+1 You pretty much NEED a launcher to use your phone. Stock HTC comes with Rosie launcher, AOSP comes with I guess you could call it AOSP Launcher. Samsung = Touchwiz launcher. You have to use a launcher, what you're asking is pretty much close to impossible

Stock Android (which Nova, Trebuchet, etc. are all based on and look the same as)

I've been a loyal Tmobile customer for over 10 years, even before they became Tmobile. However, after the terrible customer service experience I've been having with them the past few days over trying to purchasing a GS2 I have decided to brake my contact and move to a different carrier.

They have been giving me the run around and wrong information. I've had enough of their bs!

This is what they have been telling me each time I have called to purchase one. Keep in mind I haven't purchased a Tmobile phone in over 5 years.

(paraphrasing here)

Call #1 They said yes I "qualify for a full upgrade discount" and they have the white GS2 "in stock".

Call #2 , 4 days later, It's my paydays and ready to purchase..."no sorry we don't have any in stock". I said ok nevermind. I'm now thinking I 'll just buy an iphone 4 from craigslist and jailbrake/unlock it. She then puts me on hold. Different rep answers and says "yes we do have some in stock". I order one and again specifically (because I thought they were just trying to keep me happy) say "I want a white samsung galaxy s2". The guys says "no problem, I have that noted."

Call #3, 4 days later they ship me a black GS2. I called and told them the mistake. The rep said I was given the wrong information and that the white GS2 is on "back order". She was very apologetic and said they would ship out a white one asap. I said fine, i'll ship it back and wait out for the white one since I have already been charged $340 for the white one.

Call #4, 5 days later I called to confirm if they received the phone back. They said yes and when I asked when the white would be shipped she said I "don't qualify for a discounted white gs2" and that I could only purchase the black one for the $340 I was charged. I of course was furious because I had been told that I do since I haven't even purchased a phone from them in years. On top of that I haven't found a different price for a white GS2 either from Tmobile.

That was it for me. I asked for a refund and as soon as I get credited back I'm cancelling my service with Tmobile.

I'm moving on to AT&T and getting that sexy Samsung Note!

Awesome story
[Networking] fastfed:
Really sucks you went through that man.. I feel your pain..

Just really hope you don't go with an Iphone.. Don't get me wrong, its a decent phone, but a decent phone for a 3-4 year old platform..

There is absolutely no competition anymore, the tiny screens, the none existent 4g, the lack of freedom, the list just goes on.

Good luck with whatever you choose.. If you're really leaving I saw go to Verizon and get the Nexus!
[Networking] BLASTphemus:
I've been an avid fan of the jailbraking community. It's nice what you can do with a jailbroken iphone. However, since I'm with Tmobile I don't ever get a chance to browse 3g/4g speeds. That's probably the main reason why I'm moving away from the iphone and into android/rooting community.

I was leaning on getting the GS2 but today I went to the AT&T store and was blown away by the Samsung Note. I'm getting one Wednesday. :D

yup. my wife ordered me one as a surprise/gift and they sent an amaze. two months later i finally got my sgs2, $400 on a 2 year contract... if my wife wasn't making me stay with tmob, i would pay the etf and get a galaxy nexus tomorrow.

Damn y are you guys paying so much with a contact? I was only 14 months into my contract when I called the loyalty department, told em att made me an offer I couldn't refuse which included paying my termination fees and asked what they were willing to do to keep me.

there customer service may not be perfect but when calling in if the reg cs agent says thru can't do anything or basically tells you no...tell em you want to speak with loyalty department. I have yet to get off the phone without getting my way. Also when speaking with em don't ask for something, you tell em this is what is going to happen, they say O we can't do that simply ask, well fine what's my termination costs?

loyalty/retention department is your best friend

when you call 611 or whatever to call tmobile and the automated system says "what can i help you with today.. you can say etc etc"

SAY: CANCEL or RETENTION

they will transfer you to that department right away. I always talk to the reps there, because they're basically the reps who has been with the company longer and has more power over everything. They are basically supervisors (not really but could be?) to the regular reps, that means their own supervisors even have more power lol.

But anyways, any problems you guys have.. talk to these guys first because they have more access to "the system" than the regular reps, such as discounts and ****.

like bobby said he got a bogo free for $249 free everything.. this is their regular deal.. in fact it's not a deal at all. usually when you're almost 1.5 years into your contract, you're allowed early upgrade.

why is it not a deal? because... the standard upgrade price ranges from free-250 (depends if there are any promotions) so they could've just beautify and you're actually paying the regular upgrade price of $125 per phone (look into it, a lot of people either get the phone free or around $125 when upgrading). Or the phone is $249 and they credit you the $250 "credit" you get when you sign a extension to your contract and that goes into buying your phone.

Anyways! retention! thats who you have to call, I usually jump in and ask the rep whats the best they can do for me. If they say anything lower than $250 credit. that's BS. I have seen people get free phone + $250 credit. you can tell the rep that's what another rep has offered just "30 mins ago" they will try to match it, if not, hang up and call again, talk to another rep.

You know what I ended up getting $250 credit + $10 off every month of my contract. IT is usually one or the other because $10x24 = $240. And yes I have access to $10 2gb plans and $20 5 gb plans as well.

sorry for the ramble but hope this helps people save money on dealing with tmobile reps

My two cents......... I've also been with t mobile for over 12 years. Went thru the same thing as the op, with one exception i was just trying to get a sgs2. Didn't care what color it was. i was told i had to order one and that it wouldn't come till April (this was at the beginning of march) at a price of 340 dollars .

long story short, got mad, cancelled my order with t mobile and told them i was talking my business elsewhere. they told me no one in my market had this phone, and going thru them would be the fastest way to put this phone in my hands----WRONG. an hour later and only 160 dollars spent i had the phone. TARGET had 10 in stock at half the price.
