There doesn't seem to be any bug report thread on English forum, only other languages so thought it would be a good idea to post this.
Here is some bugs I've noticed, mainly related to performance.
-When you open notifications and switch to toggles, the animation is not smooth first time.
-The transition effects except default seem laggy, especially windmill. Not like this on my other Honor phone with significantly less powerful cpu.
-When you scroll to end/top of page, such as in play store or phone settings, then tap on something right away, the tap is not registered. You must wait until 'end of scroll' animation completes. Not like this on other phones I've tried.
- In balanced power mode, opening some apps such as phone dialer or browser causes the brightness to drop. Kind of annoying. The power modes should only affect the cpu.
Storage space lost after update from b100 to b121 bug.
I updated my phone before using it and storage space dropped from around 9.8gb to 9.1gb.
Space seemed to have been taken up by apps according to the storage info, but no additional apps were installed. Must be a bug where after the update, the app optimization made the phone think previously installed apps were installed again.
A power mode should only affect the cpu? Why? Its job is to save power so doing it in other ways to just cpu throttling is perfectly logical.

That's how the power mode worked before in EMU, and the brightness transition is glitchy and unsightly. It also mentions nothing about brightness changes in description, just cpu adjustments.
Most people like to set their own brightness, having it lower when you open the browser/dialer is just annoying and pointless. You can easily change brightness yourself but not how the cpu scales.

Hi guys!
I've noticed recently a new power save get option in the power saving menu in settings called 'system power saving'.
I've never seen much point in using the specific power saving mode that you can set to kick in at x% because it doesn't seem to do anything I can't and don't do manually myself.
Does anyone know anything about this new setting? Turning it on i've noticed screen transitions are a little less smooth, but does this actually do anything useful?
Any ideas?
Many thanks!

I would be interested in finding out what this does as well.
I noticed that frame rates seemed lower in games, and the responsiveness is a little slower (not considerably, though).
Is there a list of what it actually does?
I've notice that my phone uses less battery in this mode that without it.

Well, I would hope so...
I do know that it does NOT disable background data (I still receive push emails with both Exchange and Gmail)
Camera and Auto-flash are still enabled.
Everything that typically gets turned off in order to save battery is still on as far as I can tell...
We know it saves battery... but how?
If we find out how, then our developers could probably leverage that information when making new ROMs.
I would just like to know if anything is being disabled that I don't want disabled... but I don't know what I don't know
It lowers the CPU clock frequency, in my SGSII, scrolling desktops is not smooth at all with this option ON I've never been patient enough to test this option for a long time
when i activate powersaving it doesnt seem to make a difference

Seriously?
I have mine overclocked to 1.6 GHz and the conservative governor and I have not noticed the time-in-state data to be changing from what it was without this option set.
You were right about the clock speed.
system power save does the following:
Restricts core speed (mine was capped at 800)
Lowers brightness
Changes UI frame rate

Hey guys I noticed earlier that my Netflix app was ALOT smoother than it used to be before the ICS update but several others disagreed with me so I was confused. Then I remembered that I enabled this setting in the developer options menu in the android settings, "Force GPU Rendering". Make sure you enable that, close Netflix and start it back up and it should be a million times smoother after you do that. Hope this helps.
Definitely shows great improvement
Learned from GNex with ICS, this option may also FC some apps.
Do not force GPU rendering.
Leave it to app developers to turn it on and make sure nothing goes wrong. Forcing GPU for all apps will make some apps force close and some apps simply slower. If you use a lot of apps there's a chance that while some apps will be faster, others will become slower and more choppy. Read Galaxy Nexus forum for a lot of information on this.
i tired it and it didn't seem to do any difference.
Force GPU Rendering in Transformer Prime
Beware of Force GPU Rendering - DO NOT Enable it
Although some apps appear to run smoother with this option enabled, there are apps that become laggy or even crash with this option. Sometimes the touch response can also degrade. You may also see broken lines and artifacts. The option has no effect on vast majority of games that use GPU anyway. Thus, its not really worth the trouble - it is meant for developers to test/verify their older apps.
Please leave it up to app developers to turn it on for their apps - otherwise you may experience a buggy Transformer Prime with random lockups and crashes
If you do decide to use it - Please make sure you do a COLD BOOT (shut it down, and then press volume down and power button together to boot up). You may also want to clear the cache data for certain apps. This will help some apps to work better with the GPU option - and avoid some undesirable force close.
Thanks but I will leave mine enabled. The smoothness outweighs the 1 or 2 apps that dislike it (I really can't find any)
Have had it enabled since the minute I got the OTA.

thanks, I would be thankful if someone can experiment and share their findings regarding the following observation I had with my prime.
Please try Google Earth with and without Force GPU (dont forget to cold boot after changing the option) and see if you notice any subtle difference. Although at first it appears smoother with force GPU enabled, I sometimes find there are hidden lines displayed on edges of the globe. Also in a slower wifi connection, sometimes the touch response becomes less responsive, as the app waits to render/download the image data. It seems force gpu time to time affects the way the process priority is handled (touch response vs rendering of the globe). Clearing the force gpu restores the correct behaviour in slower connections.
May be this behavior is just random and isolated to my prime, but would be great if someone can try it and confirm.
It would be nice if there was a list of apps that become buggy with this option enabled in the Transformer Prime. There is a list for galaxy nexus that might be indicative of what might not work: http://forum.xda-developers.com/showthread.php?t=1372007
Also please note that for all apps that are released for Android 4.0 ICS will have GPU rendering turned ON by default with or without the "Force GPU rendering" option enabled. So, this option is for OLDER apps only, this option has no effect on newer apps and games.
As application developers start updating their older apps for ICS, they will turn it on for their apps to take advantage of GPU rendering. So, keeping your apps up-to-date from Android Market is the RECOMMENDED approach for getting the best reliability and performance.

chrome beta was design for ics so it must be using gpu for default but when i tried open the chrome settings it looks laggy and when i tried using force gpu the setting looks smooth!
Tried this on my gtab 10.1 running cm9
Enabling it makes Flipboard a lot smoother.
"Beware of Force GPU Rendering - DO NOT Enable it* "Although some apps appear to run smoother with this option enabled, there are apps that become laggy or even crash with this option. Sometimes the touch response can also degrade. You may also see broken lines and artifacts"
One answer; It can not be more worse...

Developers have all the fun
With this option enabled, if you scroll a list the CPU will not get past 500 Mhz, without it the CPU will go 100% if you scroll fast (tested it on SGN). So it is providing some battery savings at least....
ON SGN with this option enabled Reduce Photo does not work (crop FC) and SNote /SMemo is much slower.
Good, but not always the best option
Enabling this preference in developer options offloads task of rendering window components like buttons, text and complex 2d graphics calculations to GPU. This often results in much faster UI rendering including animations.
On one side you will definitely achieve better frame rate (and hence smooth experience) throughout system, but you may end up using more battery. On certain devices, GPU consumes more power the CPU, hence you may observe 5-15% lower battery life with option enabled.
offloading UI rendering to GPU has obvious benefits so that CPU can work on other important tasks like database IO, data manipulation, layout calculations and responding to other user inputs.
I would recommend having this option enabled on devices with weaker CPUs e.g. You should seldom need to enable this on dual-core 1.4ghz ARM CPU or better. Its best bet to have it switched off on quad-core CPU devices.

hi,i havent ever heared about such a booting metod guy! what the difference with normal boot from off state?
really will some apps(may be a game) toggle this option in background?how to get asured about that?
excuse bad Eng.
So after some research and Googling, I discovered that "Killling" your app is only worse or has no effect for your battery life. Even using apps that "save" battery only harm it even more. I've been told these were the fundamental things to save battery ever since I even got my hands on a smart phone.. Guess I've been asking the wrong people.
So, what are real ways to save battery? I'm a heavy phone user, often surfing the net or watching Netflix on the go. Dimming my screen is not enough, are there any other techniques to prevent my phone from dying? I've got an Android 4.
If you're rooted:
Underclock
Undervolt
Change cpu governor/io scheduler
Flash different ROMS and kernels
Change your modem
And a few more.
Not rooted:
Use screen filter? Lol.
Update your firmware

I am rooted, thank you for the info! I'll be looking into it~
Get bigger battery?
Turn thing off lol only kidding but turn off auto updates such as news etc
If you look at your battery stats, under settings, you'll see what uses the most battery. Usually I find that my screen uses around 70% of my battery, but if you have something else high on the list you might have a "rogue app" preventing your phone from going into sleep mode.
If your screen is the culprit you can only save 10% or so by throttling your CPU etc. The only way you can make real savings is by reducing screen brightness.
Easiest way to save battery is use gemini app manager to stop apps being able to autostart when you don't want them to as then you don't have the os having to kill off unused apps to make more free ram.
For example a lot of apps can autostart when your wifi goes on or off, when your 3G signal drops etcetera including things like facebook or google play. By changing auto start for such apps you don't have to run a task killer which also saves battery.

i use the aokp rom milestone 4 atm, and i also have come accross a fantastic battery app called "Badass Battery Monitor". its free and details very very specifically what apps are using the battery most.
I have managed to increase my battery by rooting out the apps i dont use that are using prescious power...
Also, turning off useless app permissions for apps theat really dont need them and work perfectly well without them will also save on power massively. for this i use "LBE Privacy Guard" works an absolute charm
I have widget where I can turn off Internet connection, set brightness, GPS etc. Internet stand-by mode uses damn much battery... And when you don't use Internet, you can put on 2G, it also saves battery.
This may not benefit you if you are a heavy user but I find the feature on my Droid 3 that turns off 3G after 15 minutes of inactivity saves battery and also saves data. Not sure if this is a standard Android feature or if it would even benefit you.
Here with LG P990 and I don't have option to turn off 3G aftre some minutes... but if/when you didn't need high speed you can choose only 2G network (for example when needed receive only notification): this save a lot your battery.
Moreover you can verify battery consumption to see if there are autostart apps from your vendor than have heavy power consumption (for me there was OnScreenPhone) and use gemini app manager as explained previously.
In the end you can find out custom ROM for your device usually optimized for smoothness and power consumption.
First apps I download when switching to a new Rom to get a little control on battery are
Adfree- Get rid of ads, they eat a bit of battery.
DroidWall- Control what apps are able to access Internet under separate "Mobile Data" and "Wifi" Conditions.
Screenfilter- Dim the screen below factory settings.
LED's hack- Turn off the Softbutton Backlights (home/menu/back/search), even though they don't seem like it may eat up your battery, it is an extra 'light' that's on, even though it may be minimal, it's still drawing power.
Also, It maybe just a Photon thing cuz of the Pentile display but I always use if not completely Black background image, a dark one because the 'lighter' or 'whiter/colorful' images take more battery, same reason I always look for 'Inverted' or black themed apps too.
Turn OFF any 'Haptic feedback' settings on your phone (Keyboard, Phone DialPad, Screen/UI Interactions, etc..)
For Calls (Ringtone) and Notification settings, don't have them set to 'Ring and Vibrate' or just 'Vibrate' because the Vibration Mechanism will eat alot if battery. Some may argue that the Notification 'Vibrate' setting and even the Haptic feedback (which does in fact use the phones Vibration mechanism) would not kill battery because it's a 'quick' or 'minimal' use (depending on use) and but if your keyboard had the Haptic feedback on, thinking of how many times your touch the keyboard for even on Text message, try will add up and help kill the battery.
Turn OFF any/all Homescreen/UI Animations
Turn OFF any Auto Sync setting and instead have APPS sync in a specified interval, (Of course Depending on how important the information that's being pulled like Email) , Could be set to like every 4 hours to sync an so on.
Manually input Date/Time settings instead of "Get network provided values" because it'll be one less thing pulling from Internet.
Set Screen Timeout to 30 Secs and Never have Auto-Brightness set, instead use a brightness toggle of some sort (Stock 'Power Control' Widget works well) to only have it as bright as you need to view in current conditions.
Open the Google 'Talk' application and uncheck the 'Auto log-in' setting, and then 'Sign out'. For some reason this always runs in the background and eats alot of battery.
If I think of more things ill post them
Hope these tips help, if they do don't forget to hit the thanks button thanks.

There are many ways...
Switch on WiFi, 3G at only using, and close the not using application, decrease display brightness etc...
And if you root your phone, you may change CPU governor, or build.prop tweaks, script tweaks... Or change to custom kernel or custom ROM.
I forgot that 'LED's hack' is not available in the market anymore, I attached it below.
i hv just downloaded screen-filter lets c how that works...
Juice defender
Try JuiceDefender by Latedroid. It helps a lot to turn off things you don't need when you don't need them. Sorry I can't post the link- I'm new to XDA
my experience:
undervolting does not help much. you have to test a lot for only a little bit of improvement.
in my opinion you will not really remark it.
but what helps, i think, is set cpu speed, if possible. for example i use samsung galaxy s2 where cpu has max 1200mhz. i set max cpu freq to 800mhz. with a good rom (hydrogenics f.e.) android keeps running smooth with 800mhz and battery lasts noticeable longer.
I agree that undervolting doesn't help so much.
Like in up post, best thing to save Your battery is to change cpu power. You can also use diffrent cpu govenor : good for battery are smartassv2 and power save. Just need to have rooted phone and download app, fx. Antutu CPU Master or Set CPU. U can also make your cpu speed profiles.
I made a lot of experiments trying to squeeze most of my GT-I8552 battery & RAM, and finally I reached those results by the below strategy (please note that this will be just strategy/tips, not detailed steps), and on ROOTED STOCK ROM It currently gives me:
1) Average Screen Off Discharging Speed 0.3-0.5%\hour (so battery needs 200 hours to discharge, or more than a week!)
2) Average Screen On Discharging Speed Between 10%-20%\hour (no Gaming) (so working hours about 8-7 hours)
3) Free RAM after full startup 65%.
(I gathered those statistics by setting Tasker to calculate them for me).
Battery Tips:
So to see almost a perfectly horizontal line of your battery discharge during your sleeping, you will need:
1) Rooted Stock ROM (I tried this on KitKat latest version).
2) Greenify.
3) Tasker
4) Your brain and some work.
OK to get most of the battery, do the following:
Remove all LG & Google Bloat ware; search XDA how to do that.
Disable all animations in you Settings-> Accessibility, this will save our battery and make apps faster.
Now all of the work should be done in Tasker, I assume that you already know how to work in this thing, if not search XDA there is a lot of tutorials...
Once your screen is off, do the following in Tasker:
Turn off the following : WIFI, Bluetooth, GPS, Auto Sync.
Greenify all bad behaving apps, after that use tasker to force close many of the bad behaved one (you should experiment with this).
Down Clock your CPU, for some reason my device reboots unless I set Governor to conservative or onDeman, so here we put it on conservative, with CPU clock between 300 and 652 MHz, there is no need to make it lower, because it gives no better battery life, and it makes wake up time longer.
Those steps are enough to make sure that you will lose about 0.5% per hour only! (my CPU needs about 5-10 minutes to enter deepsleep, this means that your battery drain during this time will more than 0.5%)
On screen ON, you need to immediately set back your CPU to onDemand mode, otherwise it will lag, actually I made 3 profiles for CPU, low (during screen of), medium (when screen on), and high (during gaming), so here I set the OnDemand with frequency 300-1190 MHz, and you will not notice any lag with those settings, also you need to set the maximum priority for the Tasker profile that will do this, well actually I made my own Lock Screen by Tasker screen so that tasker will stay foreground app and has best CPU priority, so swapping CPU profiles will be quite fast and you will see no Lag.
Also I set a periodic sync, when screen off each hour my phone wake ups and turning on wifi (or 3G if I’m out) and turning on AutoSync for couple minutes, and then turn all those things again to enter DeepSleep (step 1).
you need to make a good Screen brightness management in Tasker, there is tutorials on line for that.
Finally, during working, I set many specialized profiles for different apps I use a lot, for example, you don't need AutoSync when you are talking by phone, or reading a book, also when reading books, you don't need high CPU frequency, so I lowering it down, all this tweaks needs some work, but anyway you it will give you considerable battery gain, and you will see that the application that you really using a lot are not more than 10 apps.
I would like to note that I tried many ways to optimize this (except trying different ROMs) like playing with application's wake locks, but nothing worked as good as this strategy for me, if you have some more suggestions it will be great.
RAM Tips:
Many of us trying to make our phones customized and more beautiful, but after a lot of tries I found that all those things only making things worse, even for a monster like LG G2: I tried almost 99% of Launchers available on store, and all of them are very bad in scene of resource usage, for example the most beloved Go Launcher, having 200+ apps, and 3 pages of widgets, uses about 150 Mb. of RAM, this is too much, considering that android itself using about 200Mb. in worst scenarios, even the launchers that claims to be very efficient like Lightning & ssLauncher, that is not true, because once you install them, they indeed use too little at the beginning, but once you customize them and will add widgets, objects to them, they will jump up to 100Mb., well this still is better anyway than Go Launcher.
So to be short, the best one in terms of memory usage, is definitely, and without any competition, is Smart Launcher, it seems that it has a unique possibility to draw/load the widgets on demand (you can add them on special pages) and once you go back to main screen, it will free up used memory in minutes, that's really great, because this launcher on average uses only 50Mb. whatever the widgets you use!!
Also I would like to note that most Lock screens are very memory hungry, I tried lot of them, and none of them used less than 40Mb.!! so it almost like a second launcher! even the best of them like widget Locker or C-Locker! that why I made my own by Tasker itself, but note that after designing a scene in Tasker, it will use a lot of memory (70-80Mb.), and for some reason doesn’t free it unless you restart Tasker, and fortunately after that it will use not more than 20-30Mb. even when the scene is visible! so considering other things Tasker is doing, it's pretty low! so I highly recommend this.
Also any programs like recent app's viewers, side bars, screen buttons etc.. are also very memory hungry, I tried a lot and none of them really efficient, don't dream to get one with less of 50Mb. usage! so it's better, in my tests, "on screen buttons" are the best one with about 10-15 Mb. usage in case you don't like the navigation bar as me))

Not KitKat..wrote that by mistake..:silly:
ohk
it looks good
Why there is no rom yet that is able to update itself without entering recovery.
A rom that only needs a reboot to aply the update.
Could a rom not check for commits and replace changed files by it self and ask gently for reboot and do this maybe even by itself by time set by the user.
A rom where you can change whatever you like.
My idea is that there should be a cm rom where you can mod anything by longpressibg on it. Since alot roms come with customizations you might not need.
Imagine longpressing on audiofx option in settings and choose between cm audio fx/ viper/ dolby .... And even combine. Longpressing on performance settings and choose even an app you prefere. Totaly customize the whole settings interface by longpressing on any option and replacing such with options from other custom roms such as pac/rr/aicp/... Mixing them however we like, adding options to settings by toggling a settings icon in setrings menu. Sharing the settingsinterface with people all around the world by simply uploading a backup file created in the settings menu.
Any modification/update could be downloaded as a patch and removed again if you want to go back to stock version without a trace. Without being bloat.
Imagine the phone automaticaly uninstalling unimportant system apps such as calculator or stock music player when those are not used but allways ready to use (such apps would be shown in a separed app drawer and be reinstalled when the user tapps on its icon) and the app being backed up on a folder chosen by the user.
Imagine the stock launcher uninstalls itself when you dont use it but keeps a backup and restores itself when you uninstall your custom launcher.
We would only enter twrp for backups/flashing modems/ bootloaders and kernels.
More rom ideas:
Ram usage/cpu usage of each app shown in recents
Recents order by ramusage/cpu usage
A launcher where you can add screens aound the homescreen and not only left or right of it.
Imagine a invisible fps counter that comes with a kernel tuner that automaticly changes cpu/gpu freq to generate desired fps that you choose. And allot devs told me that is impossible and i think thats stupid because even gltools is able to save the fps as a log and apps are able to read logs so... It is basicly the holy grail idea since it could set cpu gpu so low when you are not gaming. If you leave an intense game It would detect that there is sudden fps increase and throttle cpu down. You could also modify the behaviour of this feature by setting how it should behave at a higher fps on lower cpu scales. For example automaticly limiting max fps to 20 and whike gaming 40.
For amoled screens an app that doesnt only simulate a filter by adding pixles to save battery but also having the function of turning the screen light off by reproducing a black picture on the screen withing fractions of a second and removing it again. This could also interact with the fps settings since it would adapt to the fps of the content. It would also recreat a smoother experience by showing that blackscreen between each frame (the frames would look less lasting because the blackscreen shortens its apearence)
A boot animation that looks like the first bootscreen is part of the animation.
Sound notification when wifi gets critical.
Cpu/heat or ram indicator as led light with pulserate indicating its speed and colour indicating how much cores are in use or how much ram is used combined with cpu indication.
Adaptive amoled backlight keeping energy usage of the screen allways constant. Darker contet brighter but instantly and precise in its function.
Share your rom ideas please
Thanks
