I have ongoing problems with eyestrain. Back-lit screens seem to be the issue. Have you found the SGS2 better or worse in regard to eyestrain, if this is an issue for you. I would really like the SGS2, but I may go with the Sensation if its screen may be better for me. Is max brightness on the SGS2 bearable? Reducing brightness seems to increase flicker on LED screens.
Does the job very nicely,

Regards.
Is it possible to keep SGS2 brightness at max and then use this app on top to make it appear darker? Or is Screen Filter just a replacement for the SGS2 brightness control that allows further dimming than minimum, or does it work differently?
Thanks
I havent noticed flicker on the S2's screen on normal usage unless I open up specific test patterns for flickering like this site
http://www.techmind.org/lcd/
It of course is to dimming it over min brightness for easier night reading without any sort of strain, haven't used with Max brightness as even 25% is too bright for me for normal usage and then that app with Auto brightness for night readings/browsing
Regards.

Oh. I thought maybe it worked differently since on the app description it talks about applying a "shade" over the screen.
It might work for me if it did not actually dim the LED, but "filtered" the information to be displayed so that it came out less bright. I don't know how exactly that would work, and I guess if this "software" dimming was available then manufacturers would already be using it.
I've decided to go with the HTC Sensation. I figure that the SGS2 will either be the worst or the best phone in regards to eye strain, and it's not worth the risk. Kind of bummed out since I had my heart set on the SGS2 but hey everyone keeps saying that they're both great phones.
Both phone are great but i dont seem to experience eye strain on sgs2 seems good to me...imho
I'm thinking of buying a GS2 and was curious when I read the review below on Amazon. In particular, the comments in points 1 and 3 regarding CPU/battery usage are a little worrying. Does anyone here agree/disagree with this?
**** 8 WEEK UPDATE ****
Having had this phone for two months now I thought I'd update this. There are several things now about Android and the GS2 in general that are now apparent to me and may be deal-breakers for some of you, though it should be noted that most of these are applicable to all Android phones, and not just the GS2:
1. If you use your phone as your primary music player (e.g. like an iPod) then this is NOT the phone for you - it (as far as I can determine) has no dedicated hardware to decode audio and so it uses a lot of CPU power to play music. The phone will get very hot in your pocket from the CPU heat and within 4 hours the battery will be completely dead. This turned out to be a deal breaker for me as I use my phone extensively for music playback, and the iPhone is still the only phone I know of that gives 40 hours playback.
2. Gapless audio playback is not supported by Android, though some players buffer the next track to simulate the feature (e.g. PowerAmp) if you're willing to pay for them. Gapless playback may be supported in future Android versions, though I don't know how or when one could find out exactly what version of Android will support it.
3. There is a very common bug in the GS2 whereby an application called 'Wifi Sharing' will randomly start itself in the background and consume a huge amount of CPU power (doing nothing) and drain your battery SEVERELY. Your battery will be dead in 6 hours if you don't 'force close' the application. The only solution at the moment if you have this problem is to install something like WatchDog Lite and set up an 'alert' to warn you when Wifi Sharing starts to overtake your CPU so that you can 'force close' it.
4. For all of Android's beauty and the Touchwiz inteface Samsung has put on top of it, I've become aware of some quirks of Android, especially relating to the (VERY) inconsistent use of the menu button. Many applications use this button differently (or not at all), showing different menu items on this button depending on what screen/section you are in on the application. It's definitely not intuitive in this regard compared to iOS, though some applications do use it appropriately and in a logical manner. On the other hand, the 'back' button is fantastic and I think Apple should employ one in their phones, too.
5. Screen burn-in. I've not seen many posts about this around the intertubes, but there is what can only be described as burn-in visible on the notification/status bar of the phone when you are using an application that hides the bar (e.g. having a white section where the status bar would otherwise be displayed). It looks exactly the same as burn-in looks on a plasma television; a slightly dark/grey area where the reception indicator, clock, and other indicators normally display. I suspect this is related to the super AMOLED plus screen technology though most people will probably never notice it - if they did it would be discussed in forums all over the internet.
6. Complications with applications are frequent. Unfortunately it would seem the Android market is severely fragmented due to the shear variety of different Android hardware (i.e. handsets) available. Almost every app you download will have comments attached saying things like 'won't work on HTC Desire... ' or 'If you get the so-and-so issue then uninstall, reset and reinstall' etc., etc., Coming from iOS, this is rather jarring and definitely does not fly on a 500GBP product. Furthermore, with the exception of the very common/popular applications, you are very likely to encounter flakey apps that consume too much battery power or randomly crash/force close (or 'FC' as it's commonly called in the Android community)
7. Speaking of battery power... In my initial review (below) I mentioned how awesome it is to have widgets on the home screen. This remains true, but generally at the expense of battery life. This, combined with the battery drain experienced when using the phone for audio playback will very quickly drain your battery. You will be lucky to last the working day if you also use the phone on the road to receive and respond to emails in addition to your music, surfing, widgets, etc. This may be considered an acceptable trade-off, but no one warns you of it beforehand (at least I wasn't aware of it, and just assumed I'd still get at least a full day out of the battery). I've since learned Android phones have a horrible reputation for poor battery life. Expect to last around 12 hours with medium-light use.
With all the above said, this remains an outstanding phone and by all accounts one of the very best phones available on the market. It is super-fast - faster than my laptop - and the physical design is beautiful. For any existing Android user this phone is a dream. For people coming from iOS, I hope the above update has warned you of some of the limitations on this otherwise outstanding product.

Is the comment regarding audio playback accurate? (i.e. the lack of dedicated hardware results in excessive CPU usage and battery drain)?
Sounds like an apple employee got bored...
The SGS2 is great for music playback. I use mine every day in work, for 8 hours and only ever get down to about 50%, and that's with some web browsing thrown in and texting.
Also, i thought it decoded most if not all audio formats fine? I have mp3, wav and flac files in my playlists and no problems there at all.
On my one hour daily commute..i listen to music plus screen on time at like 60% full brightness when i switch between songs whilst browsing between my news and football apps..and i probably use about 10-15%.
Wifi sharing annoys me..but i didnt notice extra large battery drops.. when i first got my phone i had wifi on all the time and it was fine. Since then i rooted my phone and 'froze' wifi sharing...so when my wifi is on...i don;t have to worry about it.
The super amoled screen gives this phone an edge on battery life above other android phones even though it still isn't as good as i hoped. And the standby time is really good.
Remember iphone battery is not removable so once you ruin it with the inevitable half charges and overnight charges your in the sh*t. You can atleast buy a spare battery for androids and keep it in your back pocket. lol jus read what i wrote...this phone has turned me into a bit of a fan boy

i dont understand this the sgs2 has a dedicated yamaha audio chip it isnt running as good as the wolfson from the sgs1 but it is still pretty decent in terms of audio quality
as for cpu useage and excessive drain on the battery i use music all day at work and its fine , it doesnt get hot , it doesnt drain battery badly , it doesnt run cpu at maximum
i use my sgs2 as my main audio device as i have bluetooth stereos in the car and home and some ok headhones from work and i dont have his troubles at all

The sound card is different from the SGS1, which was considered more efficient. This is why a few sound amplifier apps refuse to work with the SGS2 (Voodoo Sound) etc.
Obviously Samsung decided to cheap out on that aspect.
I have not seen any color burn ins, or anything like that.
You have to remember that people who dont like a product are more likely to write a review .Saying that i use Amazon reviews to get an idea about a product or alternatives a lot before buying .

Problem: For most of us, the big, bright screen eats up most of our battery power. One advantage of LED screens is the darker you make them (including using dark backgrounds), the fewer milliamps they use. So you could turn off auto-brightness and manually adjust the brightness to darker settings. Far from perfect since you must adjust it every time you go from a dark building to a bright sunny day - and vice-versa. A pain.
I recently installed Screen Filter by haxor industries. They only tout its ability to make the screen really dark for night-time viewing, with the side benefit that it will also save some battery. It works great for that. It will make the screen much, much darker than the lowest stock brightness level (even using apps which take it to its absolute lowest setting, which the stock brightness slider won't allow you to do). I've found going to 25% is perfect. It makes the screen a little gray when you go really dark but its a minor downside.
Solution: I realized it can also be set to only dim the screen a little, like 75%, or 80%. Not helpful at all in a dark room since it is still very bright. But I also noticed that it works along with the stock auto-brightness setting. So you can apply a fairly bright setting to Screen Filter and leave it on all the time, effectively lowering the stock auto-brightness level a few notches no matter what brightness it picks. You still get the benefit of auto, and you get to reduce the battery draw all the time, on the single-biggest battery user on the Note.
You can save multiple widgets on the home screen, each set to different levels, so you can turn off the 75% setting and apply a 25% setting at night with two button presses. Or turn it off with one button press in bright sun. And/or you can add it as an app shortcut which allows you to adjust the brightness from an "ongoing notification" in the notification bar.
I'm starting a test today, leaving mine on 75% all the time with auto-brightness on, and using 25% in dark situations which doesn't happen often. I expect this will produce a noticeable improvement in battery life.
are you representing the app ?...or for the company?......

Look at my post count and how long I've been on this board. No.
The app has no ads and is free, BTW.
Looks promising. Ran mine down to 5%. 15 hours on battery, 4 hours of screen time. Most people here only report 3 to 3 1/2 hours of screen time.
I just maintain my brightness, im anal like that. Especially with that notification shortcut for increasing or reducing brightness someone recently posted. i am good to go.

I use screen filter and did not think to use it all the time with auto brightness, I will give it a go thanks for the idea.
Simply setting my brightness down to about 25% and leaving it I get 4.5~5 hours screen on time.
This is still working well for me, with a noticeable increase in battery time.
I've adjusted my lowest setting from 25% to 30%, too much of a gray cast to the screen at 25%. 30% is still pretty dark in a dark room. The 75% setting is good most of the time but I've found in full sun I usually have to turn it off.
Lol at wish777, ya he is promoting a free app. Do some research before you assume and accuse someone of something.
Thanks to op for app suggestion, it works great. I downloaded it, you must of brainwashed me with your deceiving free app propaganda

Here is another, https://play.google.com/store/apps/...XJ2ZWZpc2gud2lkZ2V0cy5icmlnaHRuZXNzbGV2ZWwiXQ.. It is FREE, so no acusations. I am not the dev and I didn't even play one on TV. This one is nice because you have a single widget that pops up a window with several options of screen brightness.
ANd if you are using Juice Defender Ultimate, There is Brightness feature built in that do the same thing.

Looking at the reviews for that app, someone said that Dimmer takes the screen down farther. I tried Dimmer before Screen Filter (only for night time viewing) and can confirm it will take the Note down to the lowest allowed 10/255 where the stock brightness only allows you to go to 30/255. However, Screen Filter will make the screen even darker than Dimmer. Something to consider - not bashing any of the above. Just sounds like Screen Filter is better both for daytime and nightime use.
I use screen filter to read at night. I'm not sure about the battery savings but with screen filter set at 12.5% the screen is unreadable unless you are in a dark room. In a dark room at that level white text is more gray than white as well.

I'm getting just shy of and over 4 hours screen time, depending how long I'm actually talking on the phone for that day. Not using this app btw, wifi at home, LTE everywhere else
Actually, for me, the screen is the number 3 item for killing battery, trumped by phone calls at number one. And I dont even spend that much time on phone calls, usually less than an hour per night (I wish I could find a solution for this besides not making / taking calls).
Under Settings->Display->Auto Adjust Screen Power, I have this DISABLED.
This helps significantly with the 'greys' on a dark screen (to the best of my limited comprehension, this is being called black crush?) AND virtually eliminates the 'banding' I was seeing initially. Strangely however, I had to disable this option and it took a day or two before the banding almost completely disappeared (I was seeing it ALOT on the Google Market initial grey screen before it loads in the ads).
I use Auto Brightness.
I also have Settings->Power Saving->All Options are DISABLED.
Anyway, you might try disabling the power saving and auto adjust screen power and see if that helps with black appearing grey using the app you are mentioning.
Use the 15 toggle mod to turn of all cellular data when you don't use your phone. You can still receive messages/calls but there is no reason to leave mobile data on while at work or you're not using the phone.
I usually leave school with around 90% battery left and I'm on school from 8-1. All because I leave data off while not in use.

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:

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.

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?

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.

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?

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.

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.

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.
Overall I like the phone, but I have a few gripes. Maybe some of you agree, and maybe some of you know some solutions.
Much better than the Xperia z3v I had at first. The Xperia had a few odd things about it that bugged me, and the lack of root was getting to me. That is what made me switch.
But it did have much better battery life... I would have 50 to 60 percent battery when I returned home, the G3 will be below 20 percent most days.
The keyboard has a one handed mode, but its prediction and correction are not good. I somehow miss the space key and get run on words all the time, it's been a little frustrating. I know of no third party apps that have a one hand mode though.
The auto brightness is better than the Xperia but still not as good as it can be, it requires too much attention. It limits it's range and trays to be adjustable but it doesn't work well.
Its size has put it over my comfortable one handed use size. The one handed mode helps a bit though. Can't really do much about that. It seems to be the trend.
Its close to being a great phone but held back a bit. Maybe there are solutions to most of my woes.

Battery life for me is great. You might want to get Wakelock detector and see what is causing this. I can get 36 hours and still have 40% left. Also, it just depends on what you are doing with it. I send/receive text messages, make phone calls, surf the web, read news, etc. Usually, I have it charged before I go to bed and when I wake up 7 hours later, it's still at 100%. I leave it on all night as I use the phone as my alarm clock.
Now, I am rooted and I use Greenify to help hibernate a lot of apps. However, you don't have to be rooted to Greenify now. I don't hibernate any system apps and I don't sync a lot of unnecessary stuff either. I also have the Snapdragon Battery Guru app installed which works well. However, I will say, for a few days, I didn't root this phone, didn't use Greenify and used only the Snapdragon Battery Guru and I was still getting well over 24 hours of battery life.
I use Swiftkey and it has a one-handed/compact layout. It seems to be doing fine for me, but I don't use one-handed mode.
I feel you. Whenever I do any type of graphics intensive gaming (i.e. Real Racing 3) during the day, battery drain is crazy. When I don't use it as much, Ive had the phone go for two days. The phone seems to have great conservation when the screen is off, but that massive high-res screen has got to have something to do with battery drain. It's not the most convenient, but personally, I've found the best solution to be a quick mid-day charge. Phonearena did a charge comparison between phones, and the G3 is one of the fastest charging phones on the market right now. 2 hours for a full charge. Like I said, it's not the greatest thing to have to plug in your phone during the day, but I've found that even a solid half an hour charge makes a huge difference.

Well, yeah. Games are going to drain it no matter what and it depends on how long you play. I've noticed even with Game of War, an hour of gaming will drain it maybe 8% or more. Just depends on what you do with it.
Any phone is going to drain like crazy, but yes, the Quad HD display definitely drains the battery more due to the higher number of pixels. But, for those with every day normal use (not gaming), this phone definitely lasts more than a day.
Whenever I play a game, if I'm at home, I plug it in if I know I'm playing for a long period of time. otherwise, if I'm away from home, I know I can still play over an hour of a game and still have plenty of juice to last me the rest of the day.
I would rather have better battery than the added resolution screen. 1080p is very good for a phone.
I watch youtube and mess around online a bit on breaks. Same behavior as the z3v and dramatic difference in battery life.
I never found one handed mode in SwiftKey.
Nvm... Found it
The screen is the biggest user of battery... 60% according to the battery use chart.
These past few devices I have had... Has lead me to a conclusion.
All this undervolting and CPU throttling is pretty much useless.
The processor in this device and my last few, has had very little load on it for the most part. Some games may push the system, but general use and some youtube barely has the device going more than a couple steps above minimum clock speed.
Background services and sync... Small effects overall on battery.
It's all about that screen and it's power efficiency. Resolution has something to do with it as well. As the GPU must run harder on higher resolutions.
Turn down the brightness... And then I can't see the video I am watching.
An android phone with a current SoC, a 3000mah battery, a 4.7-5 inch screen, and 1080p resolution... Should be able to get well over 10 hours of screen on time, running video...
The radios are power hungry as well, but mostly in prolonged use like video streaming.
This size and resolution war has prevented us from gaining what we want most... Great battery life.
Still the phone ain't too bad.

True with that. This isn't an 1080p resolution screen. It's more since it's a QuadHD, so that is definitely what kills it. But, I don't watch videos for 10 hours! LOL. But, I know what you're driving at.
