Thanks to all developers for all The hard work to this comunity.
i think we all lile to come here and see a New Rom.
But in The end what is The diference from all of The roms here ?
No bugs or less bugs ?
More colours or less colours ?
I just want a stable rom with 24 hours of battery...but battery that let me use the SG2,,,use push mail , use GPS with acuracy , surf in The web ....
The iOS 4 let me do this...
I tried almost of The roms here...cant get more than 12 hours...diferent kernels...
I dont want set CPU , juice defender etc,,,i want a device that i dont want to think if i surf On The web ...i dont have battery for tonight.
I think The developers do a lota of effort..i think The sg2 is not good enough...
I bought 3 batterys ... All The same , waiting for The 2000mhn from Samsung ...last hope ...or i Will be back to iPhone .
Any advice On a good cobination / rom and kernel ?
Btw : The quality of The housing of The sg2 is poor..
Thanks for you advices , and thnks to all developers .

My SGS2 has better battery life than my iPhone. The only bad thing about the casing is the battery cover...that's the trade-off of having a removable battery. Sounds like you're using your battery wrong.

What you mean wrong ?
What rom and kernel are you using ?
Best
Galinha, there must be something wrong with your setup. On an iPhone 4 I was getting 7-8 hours of battery life. SGS2 lasts me a day at least. I'm using stock ROM and kernel.

Lol it was just a joke (remember iPhone-you're holding it wrong?).
I'm using cognition and ninphetamine. I took my phone off charge about 15 hours ago and my battery is at 73%. Made a few phone calls, sent a few messages, played wordfeud, used opera and some random stuff playing around in the phone. I suspect there might be something wrong with your phone or there's an app that isn't running correctly. Why don't you back up your photos etc and try a reset?
Definitely something is not right because for me the GS2 has the best battery life out of all the smartphones I've used!

Whats the matter
Maybe dont matter to you but i spent 600 euros in a device that after 12 hours is dead....without bat , no matter rom or kernel i use...
Realy in terms of battery all cooked roms are equal...The rom and kernel that Will make The difference Will be The one that is really battery friendly ...
Mate my phone is the best for me. i was like you wondering what im doing wrong and i got **** battery. but i read about it and chopped and changed kernels till i found the best one for me. now i can use my phone for a day or two without charging it
I am coming from an SGS and have just snapped up an SGS2, both of which I am very happy with. I am a heavy smartphone user, I can't do without them because they have made my life easier and more enjoyable in a number of ways.
There often are occasions when I would never make a full day on a single charge, on *any* smartphone. Now, one of the iPhones' several showstoppers for which I could NEVER buy one and for which I think it's an absolute POS and it's really for people who do not need smartphones, is their non-removable battery! The SGS2 has a removable one so I can't understand all the talk about having to worry and limiting oneself in using one's smartphone!!
An original Samsung battery for the SGS and SGS2 costs around € 18 here in Italy and an original desktop charger is about € 20. I had 3 1500mah batteries for the SGS and have 4 1650 ones for the SGS2. However long I am out and about I NEVER run out of juice and however many batteries I use in any given day I just charge them once I am at home! What's easier and simpler than that????
Even when I have just used a single battery and still have some charge left by the end of the day I NEVER plug in my phone at night, I put it in airplane mode and keep it handy on the nightstand to use as an alarmclock and to quickly check whatever I may need after I go to bed (an appointment, a note, something on the net etc etc). Once the battery runs out (during the next morning or whenever) I switch batteries and charge the depleted one when I am back home. So even if you can make a whole day on a single charge having at least 2 batteries and a desktop charger which can charge your battery alone, you would never have to keep your phone on the leash of the powercord and limiting your freedom in using it!
Lighten up guys..

Moving to Q&A
So, I made a switch from HD2 running android to Amaze hoping it will have a better battery life coz of its juicy more 1730mAh battery, more power efficient s-lcd screen and the fact its an native android device (which the hd2 wasn't) but its been barely 2 days and I'm seriously disappointed with it.
I'm have a moderate usage which includes calls, pandora, youtube and net surfing but it barely lasts till evening and the usage is actually less than what i did on HD2 coz I don't have put any games on Amaze yet. I had lots on HD2. With HD2 I could easily pass through the day and still have about 10-20% battery left at night and this was on its anemic 1230mAh battery
I do realize the HD2 was rooted and was running CM7 and had all kinds of custom kernels and stuff. So is stock Sense and HTC kernel the culprit here ?
I've already ticked in the setting for Power efficiency under power settings which turns off auto sync (I have google and facebook sync same as I had on HD2) and using auto brightness with the least setting, but neither of them are helping
One thing I noticed in current widget log and current widget display, is the power drain in standby hardly goes below 100mA anytime ? According to me, this seems to be the issue hogging the battery as on HD2 it used to be <10mA most of the times with occasional spikes...but in Amaze every value is like more than 100mA. Does the faux kernel and custom ROMS helps with this, a lot ?
Ideally I should try it myself and see, but don't want to unlock the bootloader and stuff just yet as if the things are going to be like this, I may as well sell it and put in some more money and switch to other side (sgs2)
The other theory I have is the CPU on HD2 is single core 1GHZ while Amaze is dual core 1.5ghz. Gingerbread doesn't have proper dual core support so things will improve when ICS comes ?
Also on a side note, is there a problem with earphones having L shaped jack on Amaze ? My primary headphones monster turbine pro which have L shaped jack don't have a very good fit in it and small amount of force seems to disconnect the headset from phone. Its really annoying, although my other earphones which have a straight pin don't have this issue. But its not the earphone problem either as I don't have this issue with turbine's in my mp3 player and HD2 ?
The stock battery was horrific for me so I bought the Anker 1900mah battery from ebay and It's far better than stock...I'm at 15 hours with 47% left...Tasker is helping a lil also.

Hmmm didn't think i would have to upgrade the battery just after buying it, although seems something wrong is with the battery though...maybe HTC just bloated its spec to 1730
Yea, I have advanced task manager with auto-kill, but its really the same with it or without..

Try letting the battery discharge completely until phone turns off, and then plug it up and let it charge to 100% without unplugging it.
My stock battery last 12-16hrs depending on use. I also have an Anker 1900mAH last a good 18-20 if I charge it inside the phone. If I charge it with the Anker charger it last about 8hrs.
Guys what about the current widget numbers ? Have anyone of you got it or can get it to see how is the drain like for you guys?
No matter how strong the battery, if its going to [email protected], it won't last very long. 18-19 hrs on after market 1900mAh battery isn't very impressive figure either
I'm not quite sure of this drain, is the fast 4g on Amaze the culprit just like LTE
Also let me know if you guys have stock or custom ROM ?

i assume youre talking about cell standby? you WANT this number to be high on the list
You should use a battery saving app like juice defender or battery fu.
Personally, I use battery fu and I have gotten more than 20 hours of battery, on stock battery, running on stock phone, unrooted.
Sent from my HTC_Amaze_4G using XDA
I havent had any battery life issues with mine. Before rooting I could go the whole day on a charge but it would be close to dead around 10PM. I'm still getting used to the new ROM I flashed but battery life has definitely improved.
I would recommend opening the task manager and killing off some unneeded apps.

Using task managers to kill an app that you don't want running isn't bad, I think its the continuely killing all apps every 30 minutes that makes it worse.

I'm not sure why this should be high
It should be low ? A high number would mean its losing more power during standby...
Guys, There are 2 school of thoughts about task manager...I agree task manager may consume more battery if you look into the theory how android works...but I've tried with and without task manager it doesn't make much of a difference from what I observed
Also what about L shaped jack earphone issue? Is it fine for everyone else?
I have the same issue my battery lasts 6-8 hours MAX with intermediate use....juice defender, tried every rom and different kernels.
My brother Easily gets 16-18 hours with intermediate use (galaxy s2) same processor. I know his battery is a little bigger but I didn't think his battery life would triple mine -__-

Hi Glacier,
Thanks for the update That seems reassuring...
I've been researching on Amaze battery quite a lot, I think current widget numbers are misleading because even in Airport mode it shows more than 100mAh drain, which is not possible..
I've found out another app...My battery drain analyzer written by a fellow member here at XDA
https://play.google.com/store/apps/details?id=com.WazaBe.android.BatteryDrain
It basically calculates the drain rate in %/hr, basically measures how much time does it take for battery to take 1% dip...
I've found for my amaze its close to 1.6-3%/Hr when in standby, when phone is not woken up during the period...I think its on a higher side but acceptable still...Can any member with a custom ROM/kernel also report his/her number..
BTW I've seen the numbers on TMO SGSII in their forum, this number is roughly the same there too ~ 2%/per hour for most users...
Hi SGS2 owners and experts. Im new here and a proud new Galaxy s 2 owner now. Im quite android savvy coming from the Spica development from Samdroid. I'v got a brand new GS2 on contract and wondering if the things I'v been experiencing are normal.
Battery life is only 14 hours with light usage and 3g, GPS and bluetooth turned off.
Phone gets warm around the camera sometimes, watching video and browsing the web.
Battery gets warm while charging.
Wifi reception is horrible.
Front facing camera is laggy.
Thats all I would like to know if its normal or should I take my phone back for new one.
Its running on Samsung firmware, gingerbread 2.3.4 XXKI1

For battery life im getting the same and im on checkrom and tried alots of ics rom im the same as u for battery life
And my device is the same the top left of the screen gets worm when multi tasking when the weather was cold i didnt feel it
But now after its summer i can feel my device getting worm abd hot when playing hd games
For battary mmm it gets little worm when charging
But if u use ur device while charging it will get hot ofc
Update to 2.3.7 or 2.3.6 the wifi will get better
Front facing camera yes its laggy
My advice update ur firmware or use custom kernel it will make ur battary and heat little bit better
If i helped dont forget to press thanks
Sent from my GT-I9100 using xda premium
yup all is normal an giv the phone some time to settle like charge and dischsrge cycle...and flash diff kernel an c which suits u.
Ya it's a bit weird to see people still on GB and not on ICS, but for sure update to latest update on GB (or try ICS).
As ayhamx360 said - try a good custom ROM. Look for one that has a lot of users and help. Check what bugs there are and anything else that's important to you (like battery life, heat, camera, wifi, etc).
PS
Most smart phones only last a day and need charging daily... it's the nature of their screens and other hardware excelerations. Newer phones will be coming with better tech that hopefully can consume less energy.
*That being said, with the right tweaks and kernels it can lost longer - mine is usually good for 1 day and 8-14hrs (1.5 days).
Your battery life seems low, but you may need a couple of cycles to get a more realistic idea.
Never had any of the other problems you mention.
I'd try XXLA4 - either stock or as part of a custom ROM. It's very stable.
Thanks for the advice. I sure feel better now. Thought I had a dud phone. Yeah I'm waiting to update ICS via Kies but old sammy hasn't released the update in South Africa yet. My phone is a little new to me to start messing around with custom ROMs like I did with my Spica. I'l prob switch to Cyanogen 9 when its stable.

I remember having much of this when I first got my S2, poor battery life, phone gets hot around camera (the cpus are located behind it) warm whilst charging and although wifi reception was never an issue, it would drop the connection if left idle for short periods of time, (sleep policy was set to off), most these will subside once you've updated to the latest firmware version, especially the heating up, and battery life will improve once the battery has been properly cycled.

Hello!
I have some concerns about the heat of my phone. I've read some threads, but everybody has different opinions and readings.
Basically, with room temperature at around 27-28, during browsing (especially with lots of scrolling through images) the phone will heat up to 40-41C (even to 42 with some encouraging) within 5 minutes, so the bottom front and back are very hot.
During other use, like writing a few messages in Whatsapp, going though settings in programs, menus etc it will, slowly, but will go up to ~36-37C.
Is it normal, or should I prepare for war with the shop I bought it from?
are you rinning a custom rom/kernel or stock? if so which?
I've found that different roms heat up more than others.
I'm using anaraxia rom 10.3 build and have no heat problems and the battery life is amazing!

Using a stock rom. I'm not experienced enough to flash custom roms yet, and I would also prefer to not void the warranty, at least since I'm not yet certain that my phone is not damaged in some way
I'm not that bothered by the heat, my only concern is whether this behavior is normal or not, and whether I should start the whole warranty war sooner.
Well I wouldn't be bothered tbh.. I've had 42°c while heavy usage and charging. If your phone overheats and burns out send it in then.. No point doing it now unless your warranty is out soon?

41.5, but how much did you strain the device? Today in a room where the temp was +-30-31C, while browsing XDA (which seemed to strain the device a bit) I got up to 44...
Also checked the idle tempretures, it's usually the same as the room temp at the moment, so it's not that it's always hot, just when used.
R: [Q] Regarding heat
Its weird that it should heat up while doing normal stuff...im on international version and last time it heated up was while i was playing modern combat 4 online after 2 hourse while connected to charger....so maybe youve got prpblems if it heats up like that only by viewing messages. I watch videos and browse the internet everyday, it never heats up. Im using stock rom and syiah ketnel...
Sent from my GT-I9300 using xda app-developers app
While doing regular stuff like messages etc it doesn't heat up much. The first test was done while browsing, but I kept it at 40% load and 1400mhz, so it can't not heat up. I think that room temperature matters, I live in a hot area, today was 31C.

I've had that "problem" (well it's not really a problem, only a minor annoyance during warm seasons) with stock rom too.
Didn't have that much experience with other roms and kernels (I'm very picky with features) but I never noticed it on Siyah with Wanamlite.
Stock kernel is far too happy to ramp up clock speeds to slightly improve response time (or so is the theory... practice is not noticeable) so it will heat up your device. More heat of course also means higher battery drain .
Note that a protection around your device usually keeps you from noticing this fact (while the phone gets even warmer due to worse cooling)

I've also noticed this heat problem, I'm also on a stock rom.
Using the "CPU power saving" in the Power Saving setting has helped, so I figured it was the kernel ramping itself up.
It's not that noticeable to run at a lower cpu frequency except that some games are sometimes choppy now
The fact that stock rom likes to ramp up the clock speeds is correct. Just by simply fast scrolling back and forth through pages on forums etc makes it go up to 1400mhz and keep it at 40% load, that's why I get the higher temps.
Well here is a problem with my battery, the thing is that my battery charges slower world what I talk about that is loaded in 12 hours or more, but that if I can not play because you are lowering the percentages just see it, I did the battery calibration and wait to be charged at 100% and nothing happened after I see the same, I read that was to change both roms, must be that these last two months I've changed like 3 times rom (paranoid, softmax, and again by the holo paranoid) then let me know if software problem or I have to buy another battery?
Or cable? Did you do a search? There are loads of threads on this issue and they all pretty much contain the answers

I'm wondering if anyone can help me out with a similar issue (wife's phone). I'm fairly certain it's not a cable issue; here's why:
I've tested with multiple cables and the issue persists. I decided to test her charger with my Galaxy Nexus and found charging was fine. I also loaded up Battery Monitor Widget on both phones and saw a huge difference. Her phone charges at 281 amps, mine charges at 685 amps. My phone runs CM 10.1, hers runs stock. FastCharge is NOT enabled on my G-Nex.
Her battery drains stupid fast. Faster than mine, and the G-Nex is not known for having a great battery, while I've generally read good things about the S3's battery.
So based on the 2 items above, I'm leaning towards an app or something that is draining battery (she installs all sorts of crap... she isn't tech savvy; but at least it's all from the Play Store). They're getting the same power from the same cable/charge (in theory), so I'm thinking an app is using the CPU preventing a faster charge. I can't seem to locate the app that's doing it. I also notice she's using a ton of data; with the Up/Down arrows flashing constantly, so I'm thinking maybe something is constantly accessing the network, but again I can't find it.
Reading battery stats doesn't seem to help since they all show the screen is the source of the battery drain. If the screen is off for the majority of the time, it wouldn't be caused by the screen, right?
So does anyone have any idea what could cause this or how I could find what app is killing network or cpu?
