I bought a Kittehface live wallpaper. I read that they didn't use very much of the battery. But after having a really bad day with my battery, I decided to go back to a still wallpaper and the battery is so much better. I hate that features on the phone are basically unusable because the battery gets sucked dry. Have to have brightness way down too.
You wold think it would only draw resources when one of the home screens is actually displayed.... I think when I had mine running a live wallpaper (beautiful widegets weather wallpaper) it only showed like 5% battery usage from android.

Hey guys, I consistently have the Captivate screen displayed as consuming about 90% and up of the battery life in the Android settings menu. Is this odd? I have the screen at the lowest brightness setting too. I don't make many calls but I do browse the internet a lot.
I have also noticed pretty poor battery life. Do you think a new battery from eBay would help. The build date on my battery says July 7 2010. I just bought this phone on craigslist and love it minus the battery life and gps.
No, that's normal. AMOLED screens use less power when displaying black pixels than normal TN or IPS screens but also consume more power when displaying non-black pixels.
So I guess if you stare at a black screen all day, it'll be more efficient.
If the pages you view have an option to change to a dark background, preferably completely black, do it. For instance I had all my e-book readers invert colors and it saved a lot of power.
New battery will likely not help. OEM batteries tend to be excellent.
I know there have been some discussions about battery, but I think what I'm about to share has not been explicitly mentioned.
It is about Live Wallpaper. If you read most forums/posts, there are people asking if Live Wallpaper uses a lot of battery. Then, most end with a response that says, "If you look at battery usage report, it is usually only 2% or so, so it shouldn't be a problem."
Well, I found that it is not true at all. I was using Live Wallpaper, and my phone's battery usage report said 2%, 4%, etc. So, I figured it really wasn't a problem. But, just out of curiosity, I tested my battery without Live Wallpaper, and I found out that it makes a HUGE difference. I mean, really HUGE.
With Live Wallpaper, By the end of the day (12~14hours), my battery was down to like 30% or less.
But, without Live Wallpaper, it lasts MUCH longer. For example, today, it's been 11 hours so far, and my battery is still at aroud 65% full. That's twice as much. The only difference I made was Live Wallpaper.
I'm sure it depends on which Live Wallpaper you use too, but don't be deceived by the battery usage report. It's not a reliable source to use when examining true battery usage.
well i thought the general opinion around was that live wallpapers DO in fact use significant battery. i've always avoided them regardless.
i had normal wallpaper with that display uses was 53%
but now with live wall paper on it reduced to 42% in one hour ??
confused
which one uses more battery simple wallpaper or live wallpaper ??

live is using more CPU !
maybe your stock background is more "light" and the live darker so the Samoled can handle the darker much better
and you cant compare 2 wallpapers cause of that thing in the settings! you did not used the two wallpars the equal time! so maybe you woke your phone with live lesser then with normal wallpaer up !

That just means the screen is responsible for a smaller percentage of the total battery loss, compared to everything else. My screen often eats about 50% of the battery. That could either mean that the screen is a battery hog, or that everything else on the phone is crazy efficient. Turn airplane mode on, auto brightness off, and screen timeout to 30 minutes. Then check the actual battery drop with each wallpaper after the phone sits idle for a half hour.
AMOLED screen
I'm pretty sure its the colour. As you may be aware, with AMOLED technology, darker colours on screen use less battery because unlike LCDs, the light is only generated where needed instead of being generated everwhere and blocked out where its not need. It also makes for much better contrast. So try experimenting with darker wallpapers if you want to get more battery life. I think the difference would be quite small though.
I'm surprised that after so much time since android has been released, people still don't know how the built in battery monitor works. The percentage shown there equals 100% if you add all of them. That shows the total energy that the phone uses and displays which apps consume it and how much of it. If it displays 100% for the android OS (let's just say, that it would display only this), it means that the only thing which consumes energy on your phone is the OS, nothing else. That doesn't mean that the battery usage is 100%, it would killl the phone in a few seconds from full charge.
So if you had 53% for the display before applying the live wallpaper and 46% after, it means that there is a new process in the phone that eats voltage.
Those values show what uses the most energy from your current total usage, it doesn't mean that the display eats 46% of your battery. The live wallpaper probably has 15% or so, but it has a much bigger impact on the battery then 15%.
Hi,
just a question just on that topic:
I got the I9023 with SLCD and i want to optimize my battery life.
What is a good % of power usage for the display? Mine is 54% and i think it's quite high, is it normal?
Is there anything i can do? I just got the phone 2 days ago, so i'm using it more often than usally (well it's new, i'm not familiar with android.) but in a week or so, when i'm used to the phone, i want to get the maximum battery life out of it.
Data:
Android 2.3.6
I9023XXKF1
Kernel

If anyone knows, how i can get a better battery life and overall performance, pls tell me, i really don't know where to start, i just downloaded the most common apps i needed, or wanted to use and used go launcher ex to get the touchwiz 4 theme on the phone, as i am more familiar with that (i had bada system before, hated it (well atleast i liked touchwiz )
Thanks a lot in advance guys!
Just wanted to get a better opinion on something I had thought of.
Does leaving the backlight on with the clock app going, perhaps like overnight. Does that bear any negative effects on the screen. Especially if you do it regularly?

Generally all screens would have a burn-out effect. But since the life span of a phone is short (assuming we change phones within an year or two), the possibility of anyone noticing it within that period would be very small to none.
It would be cheaper to get a night clock
Suggestion: If u could change the title to something like "reg. screen burnout" or something that's more related to question, it would be appreciated.
Alarm Clock Plus
I use this app for all my alarms and one thing I like most about it is you can configure it so that when you plug it in at nite ( i keep mine beside the bed) it displays the time in a screensaver fashion. I built a little stand for mine out of styrofoam that holds it at the best angle for viewing from the bed.
New to this made a wallpaper for my note and would like to share
Nice, but note should only use very dark wallpapers to save battery and screen life.

There's a difference between "should" and "could". You can use a black or dark wallpaper to save battery, but i haven't noticed any dramatic increase in battery life after using a completely black wallpaper, so i'm using whatever i want now. Light or dark, it doesn't matter unless you want to safe 0.000002% battery per hour.
Either way, very nice wallpaper! You got skills!
Some more i made like 5 years ago i dont do it any more wish i could lol

Bingo. Because unless if you leave that "dark wallpaper" image there constantly and not have anything else on your Android Home screen, there is very little battery benefits of using a dark wallpaper. Why? Simply because you'll be swiping through your home screen, some of your icons are bright, some of your widgets are not dark, etc. So effectively, as you swipe, the dark regions will be activated again and your perceived battery gain is nullified.
If you really want to save battery, turn off the screen.
thanks!!!!
nice ..
