So while i was checking around trying to find battery saving info i ran across this ....
http://jsharkey.org/blog/2010/07/01/android-surfaceflinger-tricks-for-fun-and-profit/
It's interesting in the fact that it would be nice to possibly have a toggle to switch these on or off when you are doing things not requiring the full screen colors. Like reading emails, doing web searches or reading forums (most of my screen on-time) Some of the colors would be too hard to look at but some do not look so bad. plus it may almost double the battery life - - heck even if i got 14 hours with regular use then switched onto this some of the time i could add another 7-10 hours of battery time... could be very usefull when not near a power source or during storm events and power loss.
So who here is savy enough to make the app and would it work on any rom or have to be rom specific?
There is an app called galactic night in the market. Does what you described.

THANKS. - - going to fully charge and try it out. try to match up a typical day using it vs not using it.
just downloaded. the red screen isnt as bad to look at as i thought it would be (It almost looks like an orange theme). this will be interesting to see if it will increase battery by as much as almost double. If i get 24 hrs now - i'd be pushing 48 hours on a standard battery. That would be INSANE.
cm7 and/or cm9 had this feature built into it.
Some of the filtering doesn't stick when opening some apps. I found some other threads on it and it's a known issue on US S3's. There must be a way around it though to get the red filter to stick. I'm going to message the app developer. So far it is decumbent saving a lot of battery. Not sure I'd use it all the time, but it would be a huge benefit if out camping or if stuck without power or away from it all day.

Hi Folks.
Does anyone have any idea what a safe operating temperature for the Samsung Epic Touch 4G is?
I most recently have been using the usb to hdmi converter to play shows to my TV and then running a VNC Server on the phone so I can control the Epic from my laptop to pause, play, etc. while the phone is setting by the TV.
This works great, but with the video and the server running the Epic gets up to 42 to 46 degrees C.
I have felt phones get hotter, but I don't want to damage my phone either. It cooled down to 32 degrees C pretty fast after using it as a media center.
Any opinions or technical knowledge? I ran it for a few hours, and am hoping I did not cause any permanent damage.
I know epic 1 shut down at like 110° f. might be too low, but mime got so hot on halloween after using as projection for our haunted house. Bricked the phone until I factory reset it...played movie fine, just boot lopped.

I think I took the Touch to like 114F. I did not notice the phone misbehaving at all, and it cooled down fast enough. (Well not entirely true. It kinda froze up, but that happens everytime I unhook it from the TV, seems my ADW Launcher gets glitchy when using with TV, don't think related to heat.) I think the reason it really heated up was due to using as vnc server, would not even gain charge. Yesterday when I just streamed the video to the TV without vnc, it stayed charged and seemed cooler.
The phone you used for a projection, was it the Epic or the Epic Touch? And after doing the factory reset, did you notice any issues? Slower, freezing, etc.?
Just Bumping this...
Hoping to get some more incite into the Epic Touch temperature specifications.
Thanks in advance
Bump one more time. Anyone?

I think that the phone shuts down beforehand but it would be nice to know what that number is.

Thanks for the reply John.
I would think so too. Just curious as doing the streaming etc to the TV is very convenient but not worth damaging the phone. I really think its ok to do so though, the phone has been at 40-42C with normal use. Running a bit above that has not seemed to harm it.

I think I had a run in with a rogue app the other day. My battery was draining unusually fast and I plugged it in to charge, but it was charging very slowly and the temp got up to 120F according to the widget I'm using. I rebooted and everything has been fine since.
Sent from my SPH-D710 using Tapatalk
Often times (I mean, very often) when I go to grab and use my phone I can tell by touch that it's hot and check the battery temp - those times it's usually 106° F and higher. I could tell you now that seeing my temp at 110° to 115° F doesn't surprise me at all. What kills me is that most of these times I'm not actively doing anything with the phone - I've just pulled it out of my pocket and think, damn, it's hot again.
A couple of weeks ago I updated the Widget Locker app to the latest version to try out the Honeycomb and Ice Cream lock screens, so after updating I played around with it for a while. My phone started getting hot - as in HOTTER than I'm used to. I checked the temp and it was screaming hot at 122°. What's worse is that it kept getting hotter and when I checked my battery monitor app it was definitely Widget Locker that was driving it up there. I powered off, let the battery cool a bit then rebooted. I plugged in the phone to regain some charge and checked it a little while later to see it was really, really hot again. Now at some point it was so hot it would NOT charge - stating this explicitly. I pulled the battery to let it cool and tried again later. This happened about 3-4 times before I said screw it and uninstalled Widget Locker all together. Hasn't done that again since.
So, if it helps you at all, temps around 110° - 115° have been fine for me. Over 120° would start to concern me and I think it stops charging and gives you a warning at 130°.
I've attached some photos of that particular instance. The last photo shows my temp distribution... I'm assuming all the time, and it surprised me at being an avg of 88°.
Thanks Beans! That was very useful information. I feel mich better now. Thats to bad about Widget Locker. I have used that app on occasion. I have not had a problem yet with it getting to hot on its own. But if it does I will assume its a troublesome app. Thanks again!

I used to have a problem with Widget Locker in earlier versions but the updated versions have been much more battery friendly and my phone doesn't seem to get hot from it. I am using a custom slider that someone from XDA made though but I don't think that should matter

my epic 4g touch was on the cyanogenmod 10.1 wild for the night rom v. jan23v2. every time, if my phone were off a charger for 5-10 minutes the screen would flash to different brightness levels then turn off. it would do this every time since that rom. in order to fix the issue, i tried using sfhub's el29 root to go back to stock to try flashing the same updated rom. i was on el29 rooted and the issue still occured. i would have to plug it in for it to turn on again. is this a battery issue or is it something else? my battery is over a year old. any help would be appreciated. if you need more info, just ask

Amazon will have OEM batteries. Be careful though, some will label them like OEM but they are fake. You will probably be able to get a new one from Sprint or Samsung, though.

I've had good luck with cheap eBay ones for $3-$5. (~$10 for 2 + external charger, shipped from China)
Originally bought a cheap 1800mAh for my Epic, but kept it around and am using in my E4GT (when the orinal battery "puffed" and wouldn't hold much of a charge) Recently added a "2200mAh" one and external charger. It's a tiny bit thicker than my 1800, but still fits under the stock cover. I havent noticed the "2200" giving any better battery life than the "1800" - both work well and I've had no problems.
This issue is happening to me too but seems to occur when I'm downloading something like an MMS or app, or even an image intensive webpage. The screen flashes to different brightness levels and then the battery would suddenly "drain" to zero, where the software tells me it's at zero, but with a little extra charge and a reboot, the power level will be where it was before shutting down.
And none of this occurs while plugged in so I'm reasonably sure it's an old battery, I'd just like some confirmation. What gave it away though? The flashing screen thing had preceded a loss of signal so at first (and for about a week or so) I thought that was what it was until I found this thread.

Thanks.
When I went to get a new battery, the guy pulled the battery out and spun it on the counter. If it spins, it's expanded, and indicative of being on its last leg or already dead. Of course, you could also palpate the battery and you will feel the bulge but the spin test is simpler, definitive, and more entertaining. Just posting in case someone else runs into this problem or a similar battery problem and come across this thread - try the battery spin test.
so I have just recently purchased my note8 and Im still trying to get the hang of it. I notice that I frequently qet message saying that the smart stay can't detect my eyes.
I also notice that I rarely see the eye icon lights up (I assume its there to indicate that the feature is active).and one time, the screen went blank just right after the eye lit up.
maybe, speaking from my limited exp, just maybe, the smart stay works better on devices with smaller display as the variance of the eyes/ face orientation will be much smaller compared to on an 8"device.
While I understand the benefits, the question is how many of you find this feature reliable on this tablet? pls feel free to share your experience on how it performs on smaller devices.
Im thinking I might as well turn it off in exchange for some extra battery life.
thanks / Luke
Can't share any experience using this feature as turning it off was the very first thing I did after purchasing my device
I think the drain should be way too high since it uses the front camera all the time, doesn't it? Anyway, it happens maybe once a week that the display turns off when I'm actually looking at it - at most. And just before the display turning off it dims the screen, so there is still some time to react..

I find it doesn't work as well in the dark as my GS3 did under earlier firmware and I do often get the icon. But smart stay does work well for me. Unless I'm laying down on my side.

It checks every 15 seconds of inactivity to see if you're still looking at the screen. If you're not according to your front camera, it'll dim/shut the screen.

Mine only checks a few seconds before the screen is set to time out. Ie. If the screen is set to stay on for 2 minutes, it will check at about 1:50 of inactivity.
I kind of like it except, as posted above, it can be a little iffy in low light.

I really think it is almost completely useless and simply a waste of battery. I've also disabled lock screen. Nobody touches this tablet but me. When I use it I want it instant on, and when I'm done I turn the screen off myself. I hate my devices trying to decide for themselves when to switch off, and first thing I always TAKE THE POWER BACK!
Thanks for the feedback everyone. l have been trying it off and on but at the end I would have to agree that it doesn't work for me. I cant say how much power saving I get by turning it off but it feels good to know that some resources are relieved for something else.
I use it on my note 2 (8 months now) and note 8.... it doesn't burn much battery.... it works better on the note 2 because your face is exactly straight on the camera... On the tablet.. Usually we hold it slightly at an angle.. So the camera sometimes misses off

After reading this topic, I charged my Note 2 and disabled this feature to try to get more bvattery life.
The difference is like night and day. The screen consumes a lot less power (according to the JB's Battery widget) and the battery lasts much longer.
i've never used this on any of my devices. i always seem to have this odd habit of turning off electronics when i'm not using them
A big NAY for me, I just haven't been able to get it to work even a single time, keep getting the "Smart stay cannot detect your Eyes" message again.
Is it that bad, even in other device like the S3 or S4? S4 has so many features(like the smart pause based on it, makes me think I can't use it properly), any tips how to better the usability(other than the usual ones given by Samsung)?
I realize there's been other threads about the topic, but not this specific model and this situation. Specs...
Model: SPH-D710
Android Version: 4.1.2
Build: GB27
Anyway I haven't installed any new apps, obviously apps have been updating, but I haven't installed anything new recently. It started happening just over the past three days, the phone screen will flicker, like it's struggling to refresh then I'll loose cell phone signal, the screen will lock and then power off. When I try to power back on it shows the battery drained? I plug into a power source, let it set for a minute, it shows the correct charge and I can power it back on. It's happening roughly three times a day!
Aside from being annoying, yesterday I was on the road using it for navigation, and it crapped out. I had to find a rest-stop and do the recharge dance. Thank god I had a charger, otherwise.. well I'd have to find a gas station and ask someone, but really that's so barbaric right
So has anyone heard or seen this before? I'm hoping it doesn't mean I need a new phone, it's barely a year old. When it works I love this phone, but it's such a delicate POS sometimes, it really drives me nuts. Any help would be welcome

My battery drained pretty fast, I installed Greenify and that seemed to help, however I uninstalled Greenify and I'm still having the issue.
Ok take your battery out and sping it on the flat sides. If it spins like a top replace it.

Glad to hear it's a battery issue, however I'd remiss if I didn't ask about this spinning battery diagnostic. So does the battery's casing expand when it's going bad, or getting older? Or were you just screwing with the new guy
Screwing with you. Just kidding. On these batteries when they start to swell you can aldo notice an effect on the charhe it holds. I forgot who actually found it out. But when you can spin it feely its going bad. A new battery will maybe get a turn or two.

It arrived today. Had a play and set it up as I wanted. Following the guides here, rooting took about 30 seconds (had to do it twice though) and I used flashify to flash the twrp zip. All super noob simple. No driver needed for me but I've had both LG P920 and Nexus 7 drivers installed already.
Issues so far:
Bleed - none.
Blue line - none.
Yellow hue - none.
SD card with TiBU etc - works perfectly.
Dim screen - no and in fact I set it to 60%. Full brightness is too bright.
Thin black border around screen - yes but how could it bother you?
Poor speakers - yes, they sound tinny/echoey below half volume. Fine above that. Think it's the aluminium back.
Battery drain - yes its quite fast. Set CPU to 1.1ghz and removed some bloatware its much better.
I'm sticking with the stock ROM for now. I'm familiar with the LG system and the apps are quite cool. TV remote works far better than those crappy 3-in-1 remotes from poundland.
Anyway, it seems to me that the screen issues have been resolved, at least with mine. I'm very happy with it. Any questions, fire away. Injustice is much nicer than on my phone.

What did app/software did you use to limit the cpu and cleanse bloatware?
I used ROM toolbox and titanium backup. I like SetCPU cos you can set voltage levels with a custom kernel but I don't think one has been made for this device yet.

As I mentioned in another thread for bleed there are 2 issues with this tablet. Traditional bleed which my latest tablet does not really exhibit, and edge light brightness. This is something only noticeable when brightness is at 20 and below. It is always on the bottom screen area in portrait mode and seems most visible on white background (i.e. white picture or browser page when turned into landscape to the button bar(when set to black theme) is not obscuring it. You will see about 7 bright white spots at the very bottom tablet in a row. I suspect this is a limitation of the used display technology. If you look at this video by another owner on youtube you will see what I am describing under the above conditions:

Hmmm now I am not sure what to do.
First one I bought was a white one. It had traditional light bleed in 2 corners and had this bottom edgelight issue at low brightness.
Returned it for a black one. This one is better in that it has no light bleed except the bottom edgelight issue. This occurs at brightness below 20-25. IT is not an issue during day time as I am needing brightness above 40 to comfortably enjoy the screen.
But for night time use I have to kepe the tablet a bit brighter than I prefer so as not to see it under some circumstances, I.e. landscape viewing.
I am trying to decide if it is worth returning as I love everything else about it. I am on vacation in the US and do not have the time to keep going back and forth to various best buy locations hoping for a better unit. Especially since seems the black model is in limited supply with nearest store 30 minutes away. However also given the exchange rate on my credit card, Returning it will likely cost me 20$ based on how the Credit card companies charge....
Where did you buy it from? And for how much?
eBay, around £220-£225. Can post link if you want.

what bloatware is installed on the tablet just curious ?
about to buy the tablet real soon, in regards to what you have said about battery can it last a day o more at least ?
does setting the cpu require root on this device ?
Bloatware: Well I guess that's personal preference. Stuff I won't use is some LG stuff (home launcher, LG back up etc), live wallpapers, stock browser and video player, Google books, music, movies etc.
Tablet has no chance of 1 day battery life unless you aren't using it very much. It's not horrible though, I've had 3 hours constant use this morning and I'm at 50%. Screen is under 40% for night time use though.
Not sure if you need root to underclock. I always root every device so I've never checked. I guess theoretically you do not.
