[Q] Infuse Display taking up 95% of battery usage

As someone who was looking to extend battery life, I downloaded "Battery Widget". After 9 hours off the charger and maybe 2 1/2 hours with the display on, I looked to see what was using up the battery the most. Everything from the OS to web to Wi-Fi was at no more than 2% but the display was at 95%. I know its a huge display and its going to use a lot of battery but is this much normal? The battery was dead in about 10 hours.

Sounds like you have the brightness up on it, I would turn it down a little if you have not done so already. Mine is on about a quarter brightness and it is only 79% and the battery lasts the entire day.

Are you on stock ROM? If so, you may want to consider flashing a custom ROM. When I flashed Infused ROM, my battery life significantly improved. And I am not exaggerating... I would drop 100 > 90% in about 5 hours before, now I can easily go 9-10 hours from 100 > 90% with light use.
Regarding display, please see this thread which may help with that:

My screen was on 100%. I changed it to 50%. Hopefully I will see a difference.
I am on stock ROM, however, I've been looking alot into Infused. This is my first android phone and I'm a little weary of custom ROMs being buggy. But of course those fears are pretty much unfounded since I've never seen a phone with a custom ROM in use.
BTW, thank you guys, or gals, for such quick responses.

I understand your concerns and if you are not comfortable, do not do it. However, I can say that the Infused ROM works much better for me than the stock ROM and I highly recommend it. It is much faster and better on battery. I can tell you that the version of Infused ROM I am on is not buggy and much better than stock. Cannot say anything about the latest version since I decided to stay on a previous version because I am so happy with it.

with your brightness up to 100%, i'm not surprised your display eats so much battery.
i'm still on stock and i used to run my display at 50% all the time. then i turned it down to 0% and i still have no issues seeing the screen in any kind of light, even outside. i only turn the brightness up to 50% when i'm playing a game or watching a video.
try 0%, you'd be surprised!

I have the nexus S and the Infuse. You're right, for some reason the Infuse Display percentage is WAYYY high!! My brightness is usually at 50%. But the Display is the cause of 90% of my battery drainage. It's very weird.

Okay so an update.... I've had my screen on 0% for the past couple days and I installed infused a couple of days ago as well. I haven't seen any kind of improvment. ( display is still in the 85%-90% range of battery usage.) Is it possible I just have a defective phone? I love this phone and but im really frustrated with havung to keep an eye on how much juice I have left

+1 on Infused 1.5. Rock solid and amazing battery life.

Huh weird. Im running stock and I had brightness around 30 to 40 percent and my usage for the screen was 66 percent after like 6 to 7 hrs

No I'm not watching videos. Just using the web, words with friends, messaging, and messing around with the home screen.
A little more info...... last night I unplugged my phone from the charger at 4 am with 100% charge. When I woke at 8:30 am it had 97% charge and said the display was causing 37% of the drainage( I hadn't touched it since 4:00 am). At 8:40 I started playing around on XDA app and, starting at 97%, after twenty five minutes I'm now down to 88% battery with the display causing 80% of the drainage.

It is all a matter of how much you are using your phone and how long the screen is on for. It is not unusual for the screen to eat up 75% or more of your battery power if you are contastly turning the screen on or viewing things on it.
My display is sitting at around 80% right now, and on my old Nexus One, it was usually around 78%.
I don't take personal calls while at work, so almost all of what I do with my phone while at work keeps the display on constantly. I do text and check websites that are blocked at work as well as conduct all personal or financial business using my phone.
Things like calls turn the display off and other things like streaming or playing music will let the display time out and keep working.

The things you are doing are not processor intensive, wifi intensive, radio intensive, but do work the screen.
Are you running a live wallpaper?

No I'm not using live wall paper. I understand that the display is going to use a lot of battery. I guess what I'm asking is it normal for the battery to go down 10% points while looking at Xda forums for twenty minutes. If its normal ill deal with it but if its not I can still take it back and replace it. And thank you all for taking an interest in this thread.

Actually my experience is that the XDA app has some sort of memory leak. It takes a long time to load for me and crashes about 20% of the time for me. I use the browser most the time, and find it is very well optimized for smartphones.
And yes, your battery use is fairly normal if you aren't gaming, phone calling or downloading. In fact my use is at 87% for the screen. But still, I have 70% battery left and only an hour more of work.

I am not sure if I can explain this properly. I am not a word person.
What you see is a rolling average. If you were to not use the phone at all. Let it sit completely idle without firing on the display. You would see that the display is using a low to zero percentage (of course you could not, in fact, see that). You would find that wifi or 3g or android system (or some other task) are at 95% more or less.
The display being the most power consuming component on the device will make a dramatice change to these percentages the moment your fire it. Turning on the display simply to check the battery stats will have run the display's battery percent far higher than the others quicker than you can probably even get to the screen to check the stats.
Keep in mind this is a rolling average. It does not indicate fault or that the display is CONSTANTLY drawing 95% of the battery. It is just using 90% more of the the battery than something at 5% when it is in use.
One should chalk this up to completely normal. Make a poll if you want. You are likely to find near 100% of respondents will reply that display is highest in their stats (unless they have some kind of accessory or something that draws more power)

Nexus S = TFT LCD
Infuse = SAMOLED
To reduce battery drain from screen...use more blacks. Black on SAMOLED screens are actually pixels turned off...while TFT LCD and retina displays jave a pixel displaying black.
Hope this helps put more into perspective.

tell me you did not just say that the nexus s has an lcd display... its a galaxy s phone, made by samsung. it has an amoled screen!

well, in his defense there is a SLCD version of it somewhere in europe/asia.

Why do people say they get awesome battery life with the 1S?

Why do people keep saying that the battery life of the HTC One S is awesome?
I seriously get no more than 4 hours of screen time (although the standby time was 30 hours) and thats with very very aggressive battery saving methods. I just can't get more than that. Most of the time between 2-3 hours under moderate/heavy use with standard settings.
Same thing goes for AMOLED. Yesterday I was only using the stock browser with INVERTED colors, aggressive battery saving profile and nothing else. And still, still I only got 4 hours out of it. How is this even possible? I mean everything on my phone was pitch black. Wallpapers, themes, websites. But under normal use I basically get the same results?
Has this been a lie all this time?

I´d say 4 hours of screen time is pretty good.
At least assuming you havn´t had it to min. brightness.

I think people aren't comparing the same figures
screentime vs battery uptime

4 hours of screen time with 30 hours of total use is pretty damn good for any smartphone.

I've owned several android devices and the difference in battery life from all the others to the One S is ridiculous. I really don't see what you're complaining about.

I don't think that the Battery is that great. If i use it moderate i survive a day. That is okay but not great. My galaxy S lasted a half day longer...
But it is realy useless to discuss it. There is no standard for moderate or heavy use. If i use it very low because i am busy with something else it holds two days and more...
But 4h screen on and still 30h runtime sounds pretty good to me too

I did 2 hours of on screen time (browsing the internet over Wifi, downloading apps, etc.), and my battery went from 100% down to ~70%. I'm pretty happy with that.

thats 6.7 hours of browsing while on wifi. I am not even getting 4 hours of browsing with inverted/black colors on 3G.
Guys, this phone has an AMOLED screen and I am browsing the web where virtually everything is pitch black except text while wifi/bt/gps/sync is disabled and virtually no other background processes are running except for the android stuff and one app called tasker. Auto-brightness enabled. The screen is basically off except for the text! I took it to the extreme but where are my power savings?
Even standby time is not that impressive. Anytime I am not using the browser the phone is in 2G mode, no wifi/bt/gps/mobiledata, auto rotate turned off, auto brightness enabled, no widgets, disabled all the status bar icons such as time/battery/signal icons, no wallpaper, no other fancy stuff. Just a grid of icons on my homescreen and tasker running in the background.
I had colors on my iphone and I get way more browsing time while not compromising at all with the other stuff.

Thats true. But I guess I am not even getting 1 day or 8 hours of screen time

Set the brightness down to min and/or try a custom rom. I was on stock, but I hear the battery life improves quite a bit on some of the custom roms available.
Also, this phone is significantly faster (spec-wise) than the iPhone. If you want longer battery life, perhaps you should switch to a phone that allows you to swap out the battery (GS3), or go for a low-end phone like the iPhone.
I should also add that the updated firmware 1.70, 1.78 also extends battery life. Those updates have not been released to U.S. phones yet.

OP -- seriously? Are you complaining? Find me a smartphone with better battery life with a comparable specs-to-batterySize. Droid Razr Maxx doesnt count, as its battery is 2x as large.
I took mine off the charger at work @ 5pm yesterday. It's now 10:23am, and I'm at 72%. I did a decent amount of web browsing, calls, and texting, and some music.

OP can you send me the browser apk with the inverted colors?

Stock browser has it already. Settings -> Accessibility -> scroll down a bit and you will see inverted rendering. Basically makes every B/W and inverts the blacks and the whites.
I was btw running CM9 alpha6. And seriously I don't really know about the other smartphones since I have only used the iphone 4. I believe that smartphone gets more screen time. So probably the iphone 4s too. I think the 1X and 1XL gets better screen time when I read the reviews and with the latest updates.

" or go for a low-end phone like the iPhone."
LOL!

I was confused about this for a moment. I think you think that the battery time left is what your screen shot says 4 hours and change. That's the time it has ben off the charger blnot what's left on battery. That seems normal to me for it to be @ 60

I can get almost two days of moderate use, including tethering on the stock Rom. I'm sure not every phone is equal but the battery life on this phone's exceeds my HTC Aria, iPhone's and my G2x.

His first screen shot tells us he got 4 hours and 7 minutes of screen on time and it accounted for 65% of his battery usage.
Which it way better then I get I only get about 2 hours of screen on time out of a full day of usage.
And the OP is right that IOS is the king of battery live when it comes to web browsing.

Wrong my battery was at 6% (actually even lower like 3% but I didn't take a screenshot). And the display accounts for 65% of that battery drainage. Don't you guys use android at all?
Btw according to that graph its getting 5-6 hours. But why am not even getting 4 hours max? When I did as much as possible to reduce battery consumption. Going as far as to invert the colors. I was expecting major savings. After all isn't the screen suppose to be off when its displaying blacks? I am very skeptic about amoleds now and the claims that it saves battery life when displaying dark colors. And how this is all the time used as a pro. I think its phony.
No one is going to browse the internet like me and it didnt even work

Need a good answer on my battery:

I've been debating on whether or not to go get my Galaxy S III replaced at Best Buy because of the sub-par battery life I've been getting. On average I get about 10 hours of battery life even with low usage. I keep autosync/bluetooth/gps turned off, and have screen brightness set to auto. At any given time of the day (I work from home) I have anywhere from 0 bars to 3 bars (crappy signal at my house). I'm thinking that my cell radio is what's draining the battery mostly due to low signal strength. I was wondering what you guys thought.
Also I did run CPU Spy for a few days and my phone was going into deep sleep when I wasn't using the phone.

How much screen time are you getting? I have some screenshots of nearly the same amount of time on battery as yours. I had 4 hours 20 min of screen time which I think is great!

I would start with option 1.
Option 1: If the phone works well besides battery life then see if they can just exchange the battery at Best Buy.
Option 2: Exchange it for a different phone through Best Buy if your under the 14 day period.
Option 3: Buy a good cheap battery off ebay, either an Anker or Hyperion battery. They both work well and I have used both. No NFC chip though.
Option 4: Buy a new samsung battery.

Only two hours, light - moderate use... I would say try and get a new battery. Factory reset could help but from the screen shots looks like it's sleeping fine. I would go with ^ that guys ^ ideas.
Btw I also have poor signal were I'm at for the summer, so I wouldn't think the radio is to blame.

Damn. That picture was right after a factory reset . I'll go exchange it then .

My girlfriend and I both have noticed the battery life gets WAY better after using the phone for about a week or less. I think it has to do with the battery cache and the phone calibrating itself. DONT wipe the battery cache like most people recommend, itll just restart the whole process.

let's talk battery..

so as it may be known, i came from an iPhone 4S and traded that for an HTC One X, i've had it for a little over a week and i really like it a lot BUT (you knew that was coming i think..) the battery is below par, i get about 3, on a real good day 4 hours of usage from a full charge. i only auto sync mail, screen is on 25% (also tried auto for a few days), when at home it's connected to WiFi, data off and when i go out the other way around, GPS and Bluetooth are off at all times. the main thing i do on my device is Twitter, Google+, Facebook and Instagram, + some light browsing the Internet. i understand the screen and processor take quite some battery but it's not cool to only be able to use the device about 3-4 hours before running empty. emailed the guy i traded with and he said he got about 7hrs, which would be awesome after dealing with 3-4 ;}
i am using Nova Launcher Prime, but prior to that when i ran Sense the battery was about the same. may just revert to stock to see how that will affect the battery, even though i will miss my widgets and setup. i also emailed HTC and was considering going to AT&T but since i traded the device i doubt they'll be much help.
what do you guys get... and what if anything did you do to improve it ?
thanks.

How much screen on time? 4 hours is nuts. I easily got 24 hours on stock, with light usage, maybe even a day and a half. The 2.2X versions firmwares seem to get better battery life. Just this morning I had just under 50% battery left after 24 hours, with 1 hour screen on time.
If screen brightness in on "Auto" turn that off, and set it to something like 40-50%. That should save you some, but doesn't account the type of battery drain you are talking about.
Might be some runaway processes. Or any possibility you are in a fringe LTE area?

on screen time is what i was reporting, round about 4 hours -which yea is pretty horrible i'd say. i even have the screen brightness lower; 25%. checked the processes and for what i know nothing out of the ordinary, but i'm a novice Android user so.. prior to yesterday i only used 4G when out, so at home i stayed on WiFi.
battery stats now:
- 76%
- 5h 8m 54s on battery
- screen on 59m 28s

Screen on time of 4 hours very normal, and its good for a smartphone. Everyone uses their phone differently, of course. But 4 hours of screen time gets most people through a day, and charge overnight. What type of screen on time did you get with the iPhone?

Your stats are very normal for this phone model. The One XL screen is gigantic, but isn't AMOLED and as such uses much more battery life to power than some other Android devices. I get ~3 hours of screen on time in a days use of battery, and that is about 10-15 hours away from a charger. From what I can gather of your usage, if you are looking to extend your battery life, the only thing to do is leave the screen off more.
Do you flash custom ROMs? If so, try a custom kernel that allows you to change the CPU governor and clock speeds. The processor in the One XL maxes out at 1.5GHz by default, but you can underclock it to 1.2GHz with no noticeable detriment to performance. Also you can set the minimum frequency to an even lower clock speed, which allows the phone to use even less power when idling. Finally, make sure that the CPU governor is set to Ondemand. Powersave actually doesn't save as much power as you would think!

my favorite part was when he compared a tiny 3.5" screen to a 4.7" screen and expected the same battery life, even though it is roughly the same

Firstly, 4 hours screen on time isn't bad at all. I'm sorry your only reference is an iPhone.
To get 6+ hours of onscreen time with this phone like I and many others get you will need to do two things. Firstly, flash a custom ROM. CleanROM 4.5 is a good one that's as close to stock as you're gonna get. The second thing you need to do is turn off auto brightness. Leave the brightness set at 35% - 40%. This will improve battery life immensely. And no, 40% brightness is not dim.
Happy flashing!

with my iPhone (GPS on always, WiFi always, screen on about 70-80%) i got an average of 6 hours with peaks of 7. 4 hours with the HTC One X is on a good day.

i did not flash a ROM since i can not unlock the phone (yet). where i compared, referred to the iPhone is based upon the previous owner who said he usually got 6-7 hours on screen per day. it's uncool that people not live by the rule if you don't have anything nice to say, don't say nothing... i'm only trying to get some help here (luckily most members are helpful... i'll try and ignore the others) and my other reference would be a BB Storm, which lasted very long, but the device wasn't very exciting
i'm following the thread where rooting is discussed but i believe there's little progress. AT&T is also not pushing Sense 4.1 (yet, mine has 4.0) and ICS 4.0.4.
just spoke with HTC and they agree it's too short and are willing to exchange battery... downside i would be w/o a phone for 7-10 business days. might swing by AT&T and discuss, "issue" is i was not the original buyer.. he (HTC rep) stated they might give you a loaner (i doubt it..) we shall see.
thanks to those with positive feedback.

so far..
click here for today's results --16% left.. slightly over 3hr on screen time.

It really depends on how you use your phone, and not all screen-on time is the same. 4 Hours is screen time is pretty good, and pretty on par with what other users on here have observed. The phone is new to you, so I bet you are using it like crazy. If that use includes a lot of internet, playing video, or games, its going to use more battery than some other activities. I don't know if a replacment is going to make you any happier.
You also have to consider, aside from a much larger screen, its also much higher resolution than the iPhone. Pushing all those pixels by the GPU takes power. The CPU is also much faster than the iPhone (and just about any other smartphone except the Galaxy S3), again using more power. Screen time may be less, but its doing so much more in that time.

4 hours, if I made would be somewhat acceptable, yesterday I had a little more then 3. I do not play game, I manly do social media & a little surfing..

The 2.20 OTA has an new radio. So its possible that the new radio happens to result in worse reception (and therefore battery life) than the previous one. Newer radios do not always get better results for all people, as its very geographically dependent.

Thank you for the reply and yes the radio looked like it was a new one and in PA i dont get that great of service everywhere.

Yeah, 4 hours of screen on time is normal so I definitely don't think you have any sort of defect. Signal strength also has a lot of impact on battery life. Keep brightness as low as possible while still being comfortable to your eyes (battery life isn't worth putting extra strain on your eyes). I use an app called display brightness that allows you to change brightness by swiping across the statusbar. I keep mine at the lowest level and just swipe a bit to increase it when I need it and then swipe it back down when I'm done. A custom rom could help some. If nothing else, root so that you can use something like better battery stats to give you more info on what's happening behind the scenes so you can make some adjustments. Although I'm not one to push using this, you might want to install something like juice defender to see if it helps. Verify you don't have some app running in the background unnecessarily chewing up cpu use. Note though that just because an app is running in the background doesn't mean you should kill it. As long as it's not doing anything, it's better for it to be running than to have to load it up (especially if it's an app you use frequently). A couple of other things to verify, don't use push notifications / syncing (I keep background syncing off a manually sync (well, I use Tasker to sync things at different times of the day)). If you can, use wifi. If wifi isn't available, turn it off. Also make sure wifi notifications are off and that you aren't using 'best wifi performance' (both under wifi advanced settings).
I'm sure there are some others I missed but hopefully these help and at least give you a starting place. No matter what though, enjoy your device and don't obsess too much with the battery. Once you've gotten over the 'new toy' syndrome, you should get a days use out of it. I pretty much take mine off charge in the morning and put it on charge before going to bed with around 30‰ left. Sometimes more, sometimes less. 3-4 hours average of screen on time, 30-60 minutes of calling.

Np. Been using it since early on and it continues to improve. One of those handy must have apps.

update.
went to the AT&T Device Center (did not know it existed until the regular AT&T store told me about it...) they played with my phone and concluded that the battery was draining too fast while using it, so w/o discussion they exchanged it.
got a follow up question since AT&T did not know, with the iPhones i would let them drain all the way down at least and then fully recharge and leave it on the charger for an extra 2 hours after it being 100%, i *think* that helped condition the battery.. anything you guys can suggest anything for me to to now that i have a new device to maybe improve/condition the battery ?
thanks.

Post your battery stats screenshots here!

Ok, I have to admit, I'm not the biggest fan of this phone so far (way too much bloatware, and a little laggy, IMO). But the battery life is effing fabulous. 5.5 hours screen on time with nearly 20 hours screen on time. AND THAT IS ON LTE THE ENTIRE TIME -- WIFI WAS NOT USED AT ALL.
Don't ask me why my "mobile network signal" bar has some black gaps on it. I was not in airplane mode at all and as far as I know I had a full LTE connection the entire time the phone was on.
I don't think I've ever seen 5.5 hours screen-on time on LTE on a stock ROM/kernel before, so I'm pretty impressed.
Info: Brightness manually set to ~25%. This was mostly browsing the web and xda, and using messaging. There was a short call and about 30 minutes of GPS navigation. One Gmail account syncing the entire time. Solid black wallpaper. Most of Samsung's gimmicky features disabled, and most of Samsung & AT&T bloat disabled (see my HOLY MOTHER OF BLOATWARE thread for full list).

That is amazing, even with LTE enabled it does exceptionally well.

Yep I'm very impressed with battery personally. That was my first charge cycle too--it may well improve!
Anybody else want to post? I especially want to know if I'm the only person with the black gaps in my mobile signal bar--that worries me a bit.

I went to bed for 10 hours left it idle with wifi and GPS on it only went down 2% lol

Yeah this thing gets some serious flat lines while idling.

Did you enable force GPU rendering in developer options & cut down the animations to .5 or turn then off try it out should speed ui make things faster try it out if you haven't already

I have turned off animations. Any downside to forcing gpu rendering?

So what is the technique you will be using to cycle your battery? Charge for 8 hrs before powering on. Then drain until it shuts off by itself. Or until it reaches 1-5%? Then power off and full charge? And how many cycles do you normally do? About 3 or?

Or you can just use your device normally as I don't think the battery has a memory.

Dont want to be a negative nancy here.....but given that the screen eats most of the battery, I was hoping for more at 25% brightness. I had the One for a few days, and it was set to auto brightness most of the time (which was pretty generous with the backlight, seemed to hover around 40% indoors except in total darkness, and maxing out outdoors) and it lasted me 5 hours on LTE.

Yeah I am not impressed with the battery figures considering the battery size...
Although that extra 200MHz of clock speed certainly can factor into that and nobody has really dove into what device-specific CPU optimizations each device has.

Fantastic. Nice job Sammy. Looks like respectable battery life!

Went on 16 hours yesterday so thats pretty good!

I made it 1d 1h 50m with 5 hour screen on time (50% brightness manually set) Wifi was on the entire time, mobile data was disabled and gps was on from time to time (10 hours straight at one point) It handled pretty well for its first day, got the phone set up during that time. 1% Life atm

It has a 1080p Super "Power Sucking" Amoled screen, so 5 hours of screen on time is quite good in my opinion.

Impressed myself so far...

Im really happy...watched over an hour of youtube (music festival videos) listened to over 2 hours of music...and general messing around...with everything on default settings...turned nothing off when I got the phone, and have nit uninstalled any bloatware yet...so this is with wifi on, lte on, gps on and whatever other s features are on by default and auto brightness I believe

Can someone please post the screen that shows the mobile indicator bar? I want to know if I'm the only one getting black gaps.

I could only go with about 3 and a half hours of screen time on my SIII so 5 hours is definitely very good!
