I've searched for an answer to this but I can't seem to find anything. When my GSII gets below 15% or 10% (can't remember which) it starts locking out functions like the ability to take pictures or video, and most annoying adjust screen brightness. I know this has been a problem on other devices, but does anyone have a fix or an idea of a fix for the GSII?
I'd much rather have the control to do what I want with my device than be forced to this power saving mode...which seems insane considering there is already a settings menu for a power saver mode.
I've heard this is fixed in the KE7 firmware upgrade. Not sure though
I had a topic abouth this too. It is just REALLY stupid!!!
You can say you only have 85 % of battery life, because after that, you are not in control of your phone...
If I want to watch browser info on the highest brightness with my last 15% i think I should be able too... And if I want to take a picture with the same 15% that should be possible too.
This is so stupid, does Samsung think we are kids?? If I want to save battery for something else, i will use power save mode.

Go to the VRTweaks thread in dev forum
I've got an app that lets you replace these stupid restrictions in apps with my modded versions that don't do this.
As a bonus, you can listen to music while using camera too

I'm liking what you've done so far, but it's really the removal of brightness control that's getting to me, and it doesn't look like you've approached that problem yet. I'm fairly ignorant - do you know if that's something that can be dealt with through the sorts of tweaks you're doing or is it something more complicated?

Hmmm... I thought your issue was the low battery and using the camera?
Anyway, I can look at the brightness issue, if you can let me know what appears when it happens?
It seems to me that you CAN control these settings from the power saving menu? Is that not correct?

The biggest thing for me is not being able to control screen brightness once the phone decides it's battery is low, and to a lesser extent taking photos (it will play videos at any battery level though, which looked like one of the issues you fixed with your tweaks oddly enough).
I can't remember if it's 10% or 15% remaining, but at one of those points the phone warns of low battery and automatically dims the screen to 0%, among other changes. The brightness can sometimes be forced back up, but it's only temporary, reseting itself after a few seconds or after a screen lock. The power saving menu I don't understand the purpose of at all, because I have that turned off and these things still happen. If I turn it on and set the screen brightness to a higher level, it does what I mentioned above. It's as if there are 2 power saving modes that aren't cooperating.
Is that clearer?
I used to have WM phones before (x220, SE X1), so let's say I know the basics. After a year of struggle with Android (Desire, SE X10), I'm back to where I feel at home; WM. But this time with a brand new HD2 (German T-mobile had them on stock at a very nice price). I already flashed a custom rom (Basic Energy 29.... C2.0) without any problems. I like the speed and the looks, but I am disappointed with battery life. So now I'm at trying tweaks. And here I feel a bit stuck. Apparently I forgot things.
So here are the questions;
What is the expected average battery life on HD2 on idle with all wireless connections, except GSM, turned off, and with all auto update things turned off also? (it is understandable that there is no fix value here. I'd like to hear few thoughts and experiences on this)
Is there a custom ROM that is generally known as a battery saver?
Is there some kind of a (virtual) map to show which radio is best for which region? (Croatia for instance)
Is there a specific radio which is gentle on the battery?
Is there an application to show what is (Cell, Display, Wi-Fi, CPU...) draining the battery in % like "Battery Use" on Android?
Is there an application like CPU Spy on Android?
In the tweaks, somebody mentioned the term "find battery saving wallpaper". What is this? I couldn't find it anywhere on the forum.
Is there a CPU managment application to manage (downclock) the CPU manualyl or automatically?
Is there an application similar to the Gesture search in Android (the only besides the implemented Battery Use and CPU Spy, that I miss form the Android)?
Is there a custom camera with less artificial noise reduction (I find it to be way too excessive)?
Is there a way to fit excellent X1 in ear earphones properly on the HD2. THe stoch HD2 heaphones are awful like on Desire too, and I still have those X1 earphones. The porblem is, the sound is skewed if I don't hold the answer button constantly pressed on the earphone's handsfree, so I used some tape and fixed it. However this way, I cannot use the handsfree. Can this somehow be adjusted?
Why do some part of the UI and some parts of apps look like they are scaled up to WVGA? This wasn't so on SE X1.
These are only the questions from the 36hours of use, so there could be more.
I did try to search and read about it before asking, but I couldn't find answers so fast, as the HD2 threads are really massive.
Thank you!
1... a day, day N a half.
2 ...not to my knowledge
3 ... no, what works for one wont necessarily work for the next.
4... not really, the latest supposedly has better power management, but I've not seen any evidence of that, PLUS the reception / stability is shocking on that radio, at least for me. Ask ten people you will get 8 different answers.
After using a BlackBerry for years, I am really bothered by not having a LED notification light.
I have seen posts about noled and bln, but would like some opinions
I would like a recommendation for an non-rooted phone. I am also concerned about battery life.
Thanks in advance.
we could do what IOS5 does, they use the LED flash to let people know a notification is pending..
lol, could you imagine.. dark room, and you get a txt.. then all of a sudden your camera flash is lighting up the room,

None if you care about battery.
NoLED turns on the screen and I believe also inhibits deep sleep - it'll eat battery like crazy.
BLN isn't implemented for our phones yet - I tried porting a patch for the I9100 kernels but I screwed something up, if the notification light is on, the code holds a wakelock that prevents deep sleep. As a result, that BLN implementation ate battery too. I'm hoping to eventually get it working sanely, but it's much lower on my priorities list now.

I can say, that for me, this is a big deal. I almost switched to another carrier's S2 because of it. After reading the reviews, I'm glad I didn't.
This is a great phone. Battery was a concern, but after a few battery cycles and turning wifi off, it now kicks ass for such a powerful phone.
The LEd notification light would have made it the perfect phone...lol

Hopefully eventually we'll get BLN that's stable AND doesn't wakelock the phone - but I am thinking that right now the reason it's stable is because it isn't holding excessive wakelocks.

Since noled turns the screen on, but bln doesn't, and they both inhibit deep sleep, wouldn't even this flawed BLN implementation be better than NoLed for those who really need some sort of notification light?
Its weird how this phone needs a custom kernel for BLN. The Thrill I returned had an app in the market that worked for BLN, all it needed was root. It was sweet too: you could choose different blinking combos for different notifications.
I can't complain though, this phone more than makes up for that in so many other ways. Its just a matter of time before we have it. Plus this phone has the built in option to keep those on with the screen. I was so excited when I saw that.

Hmm... I'll consider it, user clue-factor and reading comprehension HAS been better than I expected based on my past experience with the Infuse. (I was expecting to have a bunch of overclock instability reports despite the giant red text, like a bunch of Infuse ROM devs had. But I haven't and as a result haven't had to yank OC from the kernel.
Maybe tomorrow... Too late for tonight's release, that's in testing.

I totally agree. I can see you posting this with a huge battery-drain warning in large bold type and then seeing post after post after post of people complaining about battery issues.... tough call, but I'd say it's probably worth posting if it is not too much work for you to compile a version with it enabled. Easy for me to say, of course! Thank you again for all of your amazing hard work!

Are you using it on the GSII?
Ive been using NoLED from the beginning and my battery life is outstanding. I guess results may vary.
I know this may sound silly, but I just recieved my samsung galaxy PowerPack.. and I just noticed it doesnt have an ON/OFF switch!
As you know, batteries have a certain number charging cycles, and Im not always in the need for the extra juice of the power pack (but I always neet it as a phone case..)... but the power pack wont let me choose when to use its charge..
SO... im wondering if there is any way I could disable charging in the phone itself, to avoid unnecesarry usage of the power pack...
Thanks guys!

Well that would really beat the point of having a power pack. Because its advantages are that it combines the protection of a case with the versatility of having an extended battery.
If I have to physically remove anything it would beat the purpose.
So my question really goes into the software realms. A line of code or a widget that could serve as an ON/OFF switch to enable disable charging.
It's not exactly an elegant solution, but you could compile your own kernel omitting CONFIG_MAX8922_CHARGER. It might leave you stuck if you forget to switch back to a kernel supporting charging.
See this post for more information.
Okay I got the perfect 3-step solution for your complicated request.
Step 1: Hold the phone
Step 2: Slide the phone OUT of the power pack so that it barely escapes the port.
Step 3: Power on your phone, and be amazed how it is not charging while still in the case!
Congratulations, you disabled charging
But seriously, it's not fun for an average user to poke at hardware or software modifications by themselves, just stick with the simplest.
Jmmm.. I would have to give it a thought to see the workarounds.. but it could be an option.
On another hand... Im reading the power pack manual and it states that charging will be prevented if the temperature is not suitable for operation...
So my best guess is that the temperature that is being read is the one of the battery...
So if there could be a non-flashing method to fool the battery temperature meter and make it think its above the suitable limit.. it could prevent charging...
( I never Overclock my device, so Im not worried about this..)

I underestand what you mean, but Im dissapointed that samsung failed to implement such a basic feature as an ON/OFF switch...
I could have opted for one of those oversized internal batteries instead... but its not pretty, nor gives me enough confidence that it will protect my phone as this case does... thats why removing the phone from the pack totally beats its purpose...
I used to own a Mophie power pack for iPod.. and it had a simple on/off switch and was great at protecting the iPod..
Anyway... Im confident someone at this forum could find a workaround for this..
Thanks for the input
Charging
The charging process is both automatic and robust. The Lithium battery can not be overcharged and that is a function of its chemistry because the current self limits as the target voltage is reached. Multiple small top ups has no ill effect at all. The decrease in performance is both a function of time and the total amount of charge going into and out of the battery. A Lithium type battery left of the shelf will even loose 20 to 30% of its potential max charge each year.
Just use the phone as your habits dictate and don't worry about it.
Regards,
John.
You will throw away your phone for a new one before it wears out, don't worry about it.
Well, maybe you could adjust charging power to be at 0 mAh for all sources and back to normal with some app? You would definitely need root, but the question is what app allows that. In voltage control it's possible to put it down to 450 mAh minimum.

i got a solution to this problem. its very simple.. just take a very thin plastic cut it and place it between phone and power pack charging jack.. now plastic wont allow phone to charge.. and when u need power pack just remove the plastic.
OK here is the official SGS2 I777 Battery saving thread. I don't mean to be a culprit and post "another battery saving thread", but I am. So get over it. This thread is meant to maintain the battery savings threads, all in one place. INCLUDING: Battery savings tips, philosophies, and other methods of efficiently managing the charge that your battery witholds. Since I searched through basically all of the 17 pages in both the I777 and regular SG2 to collect all this. NOTE: THIS THREAD IS NOT MEANT TO ADDRESS BATTERY DRAIN PROBLEMS OR ANYTHING OF THE LIKE. DO NOT POST YOUR PROBLEMS HERE. This is simply a collection of what I found to be the most essential threads and information regarding efficient use of battery charge and battery savings. I'll update this every few months, or as I see fit. I don't see things changing much since the way a battery works, and our android os will be relatively similar over the years.
I realize that people looking for this information could just go through all the threads like any other xda troll would be the first to point out, but I also recognize the noob community for this phone (I was once there myself) and would like to be helpful in providing it all in one place to prevent others from wasting their time, whether deserving or not

THE TWO THINGS THAT KILL YOUR BATTERY THE MOST:
Super AMOLED Screen: Now it's all apparent to us at this point that android screens (S-amoled's) kill very large amounts of battery. You will save copious amounts of battery if you do not use your screen as much, hence why half of the people posting their battery stats have screen on like once an hour for half a second. They basically don't use their phones.
Data/Radio: Ever notice that when you put your phone on airplane mode before you go to bed, when you wake up it's only gone down by about 1%? That's because you're not getting any service, and have no data coming in. Believe it or not, the phones hardware is pretty efficient. CPU's don't use very much idle power at all, and I expect that to stay the same, even with quad-core processors coming out. It's mostly the over air things (and screen ) that kill our battery. Data itself uses a **** ton of battery. On a daily basis (And I've tried just about all the roms; CM7,CM9, MIUI (GB and ICS), SammyTW ones, etc.) I use a considerable amount of data. I try to have my data on most of the day since I get facebook notifiations and send/receive MMS's, but on the days where I have it off for a couple hours I start to notice, damn, my battery is still pretty high
EDIT: Using Edge/2G saves a lot of battery if you're someone who needs data on most of the day. I recently switched to instead of intermitedly turning data on and off, just having Edge on all day (for notifications) and then switching to 3G when I needed to browse or use maps, etc. Idle usage of Edge vs. 3G is probably around 40% less battery consumption (my opinion), it works really well for me.
PHILOSOPHIES:
If you want to compare your own battery life with others to get a better idea about things, check out this thread:
http://forum.xda-developers.com/showthread.php?t=1498303&highlight=undervolt
Juice Defender + others: I am a fan of this application. I used to use it for the first couple months I had the phone and it made a significant difference (mostly because of data deactivation). It makes 20-35% difference in savings from having not micro-managed anything yourself to then using the app. There are other variations of JD, GreenPower, Battery Booster, etc.

Fast Dormancy effects the trafficway in which your data makes it to your phone, both effecting the speed at which is arrives, and the battery it consumes while doing so. Check out this thread:

Underclocking and Overclocking: These are ways of tweaking your CPU usage. Underclocking is known for when you limit the maximum frequency, your CPU can clock to. So in laymans terms, what that transaltes to is your 1.2 GHz (1200 MHz) processor, can be changed to a 0.8 GHz (800 MHz) processor, if you were to underclock it to 800 Mhz. This is helpful to some almost completely dependant on your usage.
More elaborate, drawn out explanation: While your phone is idling, or sitting with the screen off, it is sitting at 200 MHz (lowest default - if you go lower than that your phone can become unstable [screen not turn on, etc.]), so underclocking won't help you improve battery usage much if you just keep your phone off most of the day. Undervolting would help more with that. if you however, find that you play lots of games, or mindless swipe across homescreens all day confused, or perhaps photo editing apps, or other things that use the maximum cpu frequency; then you will find that having your phone underclocked to 800 MHz, forces your cpu to work less during those heavy maintence situations, but in turn, prevents heavy battery drain. What this translates to in daily use: If you play angry birds, your phone's cpu might be jumping up to 1200 MHz (depends on your kernel settings - usually it's set to ondemand, in which case it will do so) during those swipes when the bird flys across the screen. However, that is not a very cpu intensive action, so if you were underclocked to 800 MHz, you probably wouldn't see any difference (lag, stutters) in your game play. However, if you were playing a 3D defense game, or esentially any other 3D game which requires you to scroll around the map, or has many many things on the screen at once (beyond fruit ninja and angry birds), then you would notice a difference in performance due to underclocking. I mention all of this because underclocking will be most effective during those situations, but it can also be the most hindering, in those same situations. All depends on how you're using your phone and what you're trying to achieve, while maintaining a certain level of quality.
Overclocking works the opposite, if you are trying to reach a certain level of performance (you just downloaded a new 3D MMO dungeon defense game and your phone is jittering and laggy during gameplay), beyond your default 200-1200 MHz clocked cpu, you may overclock up to 1600 MHz (some devs don't like you doing it - because it is essentially quite harmful for your cpu if used for a longer period of time), also depending on the kernel (again, devs created them) you may not be able to overclock, but on the majority you can.
To Underclock you will need an app called SetCpu (or equivalent) in order to change your over-underclock rate, as well as the scaling of your kernel (ondemand, performance [max frequency, all the time], conservative, etc.), also some roms have clocking options built in (such as AOKP).

AMOLEDs are supposed to be more energy efficient than LCDs I thought. That being said, I think one problem might be that many users of the former tend to keep their screens very bright because they are such a beauty to look at. I get what I think is good battery life by adjusting the brightness of my screen down when on battery only and by fine-tuning auto brightness settings.
One of the nice things about the S-AMOLED screen is that when it shows blacks, it's not using pixels. Pixels are actually turned off for the blacks. You can get further battery saving by using darker themes and inverted apps. Of course, that's not to everyone's liking. Me, I tend to like darker, tending towards minimalist screens as opposed to bright, busy ones, so it's a win for me.

First, in reading my paragraph I was speaking of JD's helpfulness in relation to not micro-managing (turning off data, etc.) anything yourself. In this case JD helps a lot....
Second, I didn't bash any part of our AMOLED screens, but they use a lot of battery...idk anything about how they compare to other screens, and idc...that has nothing to do with my post. We all have I777's, and that's the way it is, so I'm not too concerned of other screens.
I will say, that in light of reading most of your comments (which are found everywhere) , evidently, that you do at least make a good point, most of the time.

Yes data drains battery. If you are rooted (I hope you are since you are reading this on xda), you should get Droidwall. It's a firewall for your phone which limits certain apps to use network data, wifi data, or neither. Useful if you are also a little bit paranoid :silly:.
Another amazing app I also use is called llama. It is similar to tasker but it's free. This app allows me to set profiles and actions based on location (antenna mast instead of GPS to save battery) and other triggers. Not sure how ICS manages BT and Wifi scanning but those things use to drain my battery under GB so I got into a habit of toggling them on/off. Llama can do it automatically for me because I am lazy or sometimes I forget to.
I think any phone screen can be a big battery drainer if left on long and are set really bright. I have a habit of hitting the power button after I am done using it as opposed to just letting it shut off by itself.

They are more efficient than LCD's, and I made no notion to say they weren't. I simply said that they were one of the two main culprits of battery drain. I'm not saying our phones suck cus they have AMOLED screens, it's actually awesome. I'm just saying, like any other phone, having the screen on lot is going to kill your battery.
Yeah on stock (rooted after a month) I used to use auto-brightness most of the time, and sammy's auto seems a little brighter than necessary by default (so I'd keep it on 40% some days). But after switching around to different rooms (before I started tweaking auto-brightness) having brightness at what I'd actually consider an adequate level, versus a little bit brighter makes a huge difference. When the screen looks just a little too dull in all situations it really takes away from the experience hah
Also, I know black pixels are technically off on AMOLEDS, but I've noticed on many occasion when using in a room with no light on at night (pitch black, essentially) that when rebooting and hitting the yellow triangle screen (mostly black) you can see the black area of the screen. It's not completely black. It's definitely a very real looking black, but it still looks like there's a backlight behind the screen. Is that the case? Can anyone confirm?

. . .idk anything about how they compare to other screens, and idc...that has nothing to do with my post.

While it may not have anything to do with your post, per se, I think it's a good idea for people to be educated about our screens since many *are* coming from the LCD world and some of the rules they're used to don't apply. And some of those rules very definitely have an effect on battery life, like the rendering of blacks that I mentioned above.

They are more efficient than LCD's, and I made no notion to say they weren't. I simply said that they were one of the two main culprits of battery drain. I'm not saying our phones suck cus they have AMOLED screens, it's actually awesome. I'm just saying, like any other phone, having the screen on lot is going to kill your battery.
Yeah on stock (rooted after a month) I used to use auto-brightness most of the time, and sammy's auto seems a little brighter than necessary by default (so I'd keep it on 40% some days). But after switching around to different rooms (before I started tweaking auto-brightness) having brightness at what I'd actually consider an adequate level, versus a little bit brighter makes a huge difference.

That is the case with LED screens. In a mostly black scene, the individual pixels for the black area are not lit, however there is still a backlight lighting the screen itself which you may see bleed through. This is of course assuming the phone LED works at least somewhat similarly to a TV.

Yes I agree with you on that. It is more the manner of criticism which he spoke it that I am not favorable of, not necessarily the information which he shared. Which is why I wrote what I did at the end of my comment.

Ahem....let me try to get his thread back on track.
I agree wih your comments vanillacracker. On a gb rom if I disable auto sync it helps me a lot wih battery life because he signal is really awful at my work. So I guess if the signal is bad it tries to sync amd keeps doing it for a long time whih really drains the battery. Disabling background data helps even more but I like to get my emails so I do not.
Sammy based roms are the best wih auto brightness quickness. Aosp roms are always slow to react. I hate when I step outside and the screen takes for ever to adjust. But the sammy based roms also have high default brightness as you mentioned.
Ps: do not feed the trolls. Just report them.

I will agree with you on most of your points and yes you are correct about the signal, the worse your signal is the more it affects the battery. Also, tasks aokp has the option now to change the reaction speed so if you like aosp but hate the reaction speed that is an option.
How exactly was I trolling? I know you're referring to me, I made a criticism of two points out of the entire thing and he tells me I'm a troll and that I need to take an anti depressant. What exactly did I do wrong?

Ohh alright that makes a lot of sense then. Thanks a lot, that was really helpful for me! Yeah cus in the completely black screen sometimes I can see the little splotches that look like it's where the backlight is squished against the screen or something. I noticed the marks are in a different spot on my current I777 than they were on my old one (replaced cus power button stopped working). Yeah it would make sense that AMOLED's came around the same time LED's started getting more popular in TVs too (few years ago), pretty baller technology for a phone! I'm loving it haha

Way to come back with a personal attack, it's been proven in many cases that JD does not help and if anything hurts battery life. I used to use it and now I don't with no hit on battery. I'm not depressed thank you very much. I reported you for that one. I wasn't saying anything bad or personal but you had to go ahead and do it.

I disagree with you that Juice defender does not improve battery life. I am aware that obviously running an app in the background (Juice defender in this case) uses battery. But if the app is disabling your data (data uses battery..more than the juice defender app uses) then it's not possible for it to not increase battery.....just logic there. Anyway I'm sure there's been reports that say it does and does not increase battery, it's been obvious to me that it does, and it's logical to assume it does (if you know what I'm addressing) too. So I'll say to each their own. I do not wish to argue about things anymore, I will not edit my thread to your liking, you may simply dismiss that tip if you'd like.
I do not care about a report, I'm sure most people see the way I act and understand my reasoning. I probably overreacted a bit to your initial response , I've edited my accords. :cyclops:
BTW, VC, thanks for the compilation. Hopefully it will prove useful to folks!

Dude.....no offense but your first post was pretty disrespectful....hence my comment. However your quoted post was very useful. I believe in one thing...you give respect you get respect.
Now...getting back to the topic....good point about tasks rom....I did try it out but frankly speaking it is still not at par with sammy base roms wih regards to auto brightness. It does rock otherwise.
I am currently on ktoonsezs MIUI port (love that guy. No homo)....and m pretty happy with the auto brightness

If the only thing which is holding you from using aokp is the auto brightness, there is a flashable zip in the fluxxi thread which gives great settings.

OLED screens do not have a backlight. That is one of the things that make them much more power efficient than LCD. The pixels themselves in an OLED display generate light.
