S amoled screen, cell standby, and battery life

So the screen is supposed to have less drain on the battery? Why does it drain 80% of the battery consistently? So if this phone had a regular lcd screen it would only last 3 hours?
When I'm at work the service sucks and my phone is constantly searching for signal. The battery went down two % in a minute and goes down 5-6 every hour if not more when not using it. At home I don't have this issue and I get much better performance. I pimped my phone out and I feel like this is the cause of such short performance. The phone is much more responsive and I love it but if I want to make it through a day I can hardly use the thing. Just posting this thread caused my phone to go down 4%

If your phone is constantly searching for a signal, then you will see rapid battery drain.

I have not had this issue with other phones. At least not this bad

lol switch to the dell streak or the evo, you'll then truelly be able to appreciate battery life on the captivate.
in general though, it seems like you're having some bad luck with your battery. Some users suggested doing some power cycling and a factory reset of the phone. I also highly recommend reading the pimp my captivate pdf. Nifty little section in there for battery optimization.

When was your phone purchased? If you registered it, did you happen to notice the manufactured date?
if your phone is on standby, when you go to settings-about phone-battery- What is eating the battery?
My first Captivate would drain the battery (even in "standby") about 2-3% per hour. Even though the phone would be on standby more than on, the DISPLAY was eating the battery life more than "cell standby"
my 2nd captivate - battery is lasting much longer - took it off the charger Friday at 7PM - am currently at 34% - and I've used the web browser/navigation/browsed the market, made phone calls, etc)
When I view the battery settings, "cell standby" is first in line..
Also, when I do keep the phone on standby, the battery BARELY drains.. I'm talking maybe 1% for 3 hours
Oh, the GPS works on phone #2 as well. My 2nd phone was manufactured 7/20, first phone was 7/10

Is this how it is for most people? My battery history always shows display as the number one battery consumer at 65-70% no matter how I use the phone.

If you went down 4% just posting, then it sounds more like a battery issue. Can't really help you there. But the crappy service at work thing - have you tried seeing if flipping from 3g to edge helps? In my office, my 3g signal is bad - 0-2 bars, constantly fluctuating. If I filp to edge, 4 - 5 bars the whole time. You could definitely save some battery there, if it worked for you. Here's the thread for changing to 2g: hxxp://forum.xda-developers.com/showthread.php?t=737137

FYI - Checked battery at Midnight last night- battery status was 32%
Battery is STILL at 32% this morning.

If my phone is idleing, i hardly lose any battery percentage.
I use Juice Defender to help my battery. i can easily get 2 days out of it if I use my computer to browse the web, but sometimes it's just easier to use my phone if I am at home or laying in bed.

Some of you are getting some very impressive battery life, I cannot seem to compare.
My battery went down 5% over 6 hours. Which is a huge improvement over the 30 percent it did before.

My phone has been off the charger for 15 hours and 26 minutes. About 8 hours of which I was asleep and the phone was in standby. My display is still listed as #1 in battery history at 52%, I don't understand how anyone gets the display out of the #1 spot.

if you don't use the phone, it wont. I've had it where my display and idle were about the same, but that's because i haven't used it.
If you make a phone call, the display will turn off and your cell service will take over the #1 spot.
The display will drain the battery the fastest. Even if it does suck less juice than before, it is still more than android needs to run. If you take the display away and give it a black and white that you find on E-Readers, I bet this phone would last for days and days. You are paying for a 4 inch screen that is gorgeous. Of course it is going to use battery life. There aren't any other ways around this.
EDIT: I'll play around with it for the next few hours while i'm hitting golf balls and then I'll break it all down and we'll see how my battery has been affected.

For those of you who don't have there screen with the main drain what do you have it set at? I have auto brightness on and power saving on. Maybe these cause more problems. With the screen constantly adjusting our drains more than it save s

Voice calls is in first at 52% and display is at second with 38%. I get amazing battery life out of this device. Again I am comparing this to a BBC bold.

My battery would drain down twice per day.
If I was going to turn off background data, browse on my PC, and micromanage all the settings... well, I wouldn't have gotten a smartphone.
I would have preferred a slightly thicker phone to go with a larger battery. Samsung had the option with the BlackJack with a bigger battery & second battery door.

1500 mah is the largest battery in a phone yet. I am sure someone will release an extended battery which will also add thickness.
Typical Android devices get terrible battery life from what I have heard.

I'm not at all surprised that my display is the #1 factor in draining my battery. I bought this phone for its display.
What I am surprised to hear are those people who own this phone, use it, and don't have their display as numero uno in their battery history. I have to imagine they either: 1) don't use the phone all that much (e.g. have it in standby most of the time), 2) only use it for phone calls & texts, or 3) have their brightness/other settings set up uniquely.
I'm most interested as to whether #3 is true. If that's the case I'd like to find out what those settings are and try them out myself.

Battery life VASTLY improved since update

unplugged 2 hours, wifi on, gps on, auto update on, facebook, played friut ninja for about 20 minutes, 1 game of cribbage, and been getting 4-5 email per hour, battery at 86%, before I would have been at 60% with that much use.
Anyone else seen battery life increases?

This. It's noon and I'm still at 80%. I used to have to set my phone to flight mode all day at work just to make it through the day. Now I can leave 3G on all day and not worry about it. That's the best part of the update in my opinion.

I was about to post this also. Yes, I have noticed a dramatic increase in battery life since I've updated. Now granted, it's been less than 24 hours but it is noticeable. I'll see how it goes over the next few days. But I agree, I am very happy with the update so far.

Which ROM we're you guys running before? FJ6 (stock)? A lot of users noticed better battery life after updating to some of the leaked builds (JH2 onwards)

6 hours 53 minutes since unplug and I'm at 23% battery. This is roughly on track with previous battery depletion, but today I've been doing heavier internet and Facebook use than usual. I think that, previous to this update, I would have had to charge by now. This is with background data and sync on, over wifi, with a combination of Google Listen, Music Player, and Pandora use.
The telling point is that screen battery use is about 10-12% lower than usual for this type of usage, at 54%. I've seen it as high as 70% on days when I'm playing around with the phone a lot.
I'm ready to call this an improvement.

My phone was at about 75% at around 8:00PM last night. It's currently 2:42PM now and it's only down to 25%. Granted, it was in sleep mode from around 12:30AM to about 7:00AM. But I did use it moderately last night and throughout the day today. So the battery performance has definitely improved for mine (stock with yesterday's update).

For those who have seen an improvement:
- Did you use a task killer pre-update?
- Are you using one now?

Unfortunately my battery life has been greatly decreased by the update. My phone is rooted, but the update installed without any trouble on the first try. Before the update the phone was fine between 9am and 1-2am without charging it at all. That's being on wifi most of the time, and maybe a bit of talking, e-mail, and rss reading. Once asleep I'd let it charge overnight. Typically Display used the most battery, usually about 50%.
Since the update I find that I need to charge the phone in the middle of the day. The first full day of the update I used the audio player for several hours, so I thought maybe that was it, but I've done that before without a major impact on the battery. Today I didn't use the audio player at all, and after 8 hours the battery is down to 26%.
According to the power usage information the largest consumer is Voice calls, at 29%. That was 11m 46s of call time. Looking at Juiceplotter, for a typical day at work before the update my battery dropped about 2% in 2 hours, with the phone on wifi, and otherwise idle. Today the phone lost 6-9% in 2 hours of being idle.

The last time I charged my phone was yesterday morning. I just plugged it in an hour ago at 15%. Thats like, 35 hours on a charge after moderate usage. Not bad. Much better than my old G1 heh.

I'm at 45 hours, still at 29%. Light usage, probably ~12 hrs in flight mode, but music player on for about 5 hrs, 5 min voice call, a few texts, some facebook/web. Still very impressive!

I've had slightly better battery life since the update.

[Q] Actual battery life

Hi guys, any thoughts regarding Battery life? I get roughly 8 hrs, not the 9.5-10hrs advertised/reported in the forums. Of course, this is with very high use, screen on 7.5hrs, wifi on the whole time, plex on for an hour or so, mobo video playing for an hour, and web browsing for a couple of hours, and some games too. Is this standard? Dock battery is ok, gives around 5 hrs. Any ideas on improving battery? Screen stays at 60% brightness all the time. Plus i have cnn, facebook, youtube, pulse, cnbc and plume widgets on. And active mail sync in the background.

The 9.5h time is stated for constant 720p playback so I don't think your usage is that much higher. I never stopped the time for my ASUS but I am happy with it and I guess that's what matters most.
I use SetCPU (requires root) to set the clock speed to 216MHz when idle. That seems to improve battery life.

I am not getting anywhere close to 9 hours. At first I thought it's the apps I have been running in the background or the brightness, but it's the same after I adjust it. I get about 6 hours.

Dude....6 hours is pretty low.anyways, i havent rooted it yet because of the impending otas.will do it as soon as a gr8 custom rom comes out.

Yes but i do video streaming over wifi. Also my wifi is on the whole time. And as far as i know, wifi takes more battery than video decoding.
Sent from my Transformer TF101 using XDA Premium App

The 9.5 hours is for
Airplane mode
playing a local movie, only
display at about 30% based on the NITS listed and Anandtech measured brightness
I bet you can achieve the same if you duplicate their testing scenario.
As for improving battery life decreasing screen brightness can have a huge difference. The screen is often the #1 power usage item when I check on my phone. Also, reduce the checking frequency of any task that needs Wifi to get data.

It's been 15 days now since I had the TF and I can tell you based on my usage - I used up;
12% per hour - airplane mode, play games watch movies in auto brightness
1% per 2.5 hours standby.
So more or less 9 hours usage should be achievable.

I get about 18 hours of constant use with dock

I play with the thing all the time and I honestly haven't ended a day with my battery being below 50% yet.
Actually, out of fairly constant use, I haven't charged mine for, let's see... 2 days, 6 hours, and 52 minutes. Currently at 48% charge.
EDIT: Oh, and I don't have the dock, so it's not counting that.

It stays on auto. When it lasts me multiple days, I can't say I really worry about saving battery much.
For example, I unplugged it this morning at 7, played with it quite a bit today including playing Zenonia for a little over an hour and letting my friends play around, and my battery is currently at 75%.

Hi all. I just wanted to chime in on this thread here. Im a former owner of a xoom and can say that tablet was a beast when it came to battery life. I could have a full charge last for 2 weeks+ with very minimal use all consumed by idle standby. That was something to be said. The tf isn't as good; I can tell already, but I was surprised today! I charged it overnight and unplugged it around 11am. 98%, until I woke it up right now! Its at 97% with 13 hrs 39min. I probably had the screen on for only 5 minutes, but pretty good! One thing to point out that helped me a lot was to always have the tab in airplane mode. You can still have the wifi on and stay in airplane mode. That seemed to make a difference with the xoom. Just my $.02

I get 5ma constant use in sleep mode. By that logic, u would lose 1% in 13 hours on sleep mode. So yeah, idle use is pretty good. Decent tested flight mode yet though.but seriously, y doesn't battery use show the percent divisions like my phone? :O

Its doesn't seem that any of you guys are reading the manual when it comes to battery.
It says it clear in the manual. Why not follow what the book says, I guess some dont read.​
"If you intend to use battery power, be sure to fully charge your battery pack before going on long trips.Remember that the power adapter charges the battery pack as long as its plugged into the computer and AC power source. Be aware thats it takes much longer the charge the battery pack and when the Eee Pad is in use"
Remember to fully charge the battery (8 hours or more) before the first use and whenever it is depleted to prolong battery life. The battery reaaches it's maximum capacity after a few full charging and discharging cycles.
"To prolong Battery life, charge the battery for up to 8 hours when using Eee Pad for the first time and whenever the battery power is fully depleted.

Mine is more like 7%/hr, which is totally unacceptable, I have all sync turned off, except exchange... with my HD2 running Froyo, I could do 2%/hr with the same settings.... I am still trying to figure out what's draining my battery...
I have also noticed high data usage.. I've tracked it down to T-mobile's AppPack. I've never used the program but it's constantly draining away my data... Is there a way for me to remove the app or disable it?
Thanks!

Get Watchdog from the Amazon appstore to find out what's draining your battery. I believe it costs, but it is a thoroughly useful app
Don't think we can remove carrier apps until we have root...that said, you could try adb pull, but I'm not sure whether it will have any effect. May need root for ab pull, in which case we can't get rid of carrier apps :/ sorry

this has the best battery life ive ever saw. I'm in 0ma all the time the phone yesterday lasted from 530 am til 7 pm at night with a lot of text and playing games like homerunbattle 3d. If you play that game you know how much of a battery hog it is. Best battery life. Battery was soo good i barely charged it went to work with a 40% battery and it easily made it through a day with moderate texting all day!!

Gotta say... coming from a TBolt this thing is like sex in a tin can.
Idle is 1-2%/hr probably. I would get 10%+ on my TBolt at times... if not more. It was bad.

today is the first time I'm having issues. Only 4 hours since charge & down to 40%. The Awake time shows as 99% of Up Time. Is that normal??? Also, anytime I look at the task manager it shows wifi calling running even though I have it shut off

I've got an Asian model sensation (ie. 3g and not 4G model ) and I find my battery isn't really calibrated properly so its hard to comment on average percentage drop per hour. I've recharged my battery 3 times already and i find the battery stays at 100 percent for around 30 minutes of constant on web browsing, then it will drop at a rate of 10 percent every half an hour with constant use and will fluctuate.
To report on a rough usage breakdown, with all background syncing disabled, I managed to get 10 hours standby before my phone dropped below 10 percent. This was with 5 hours of screen being constantly on doing mainly web browsing on 3g and one 15 minute phone call using my wireless Bluetooth handsfree.
I can report the battery life with constant usage is better than what i got with ny hd2. Running android ROM, it used to do around 3 hours of constant web browsing before the battery will fall under 15 percent. In standby my hd2 used to drop around 1% per hour, which was quite excellent.

Those are the stuff I'm talking about, it appears that one of the settings and/or app is constantly using the processor, which causes the phone to stay awake even when the screen is off... I just haven't figured out which app is causing the problem.. I am suspecting it is one of the Tmo apps.

I'm looking at a full battery life of 11 hours, 49 minutes with moderate usage (some calls, decent amount of texting, some games). I use the app/widget "Battery Left" to do its own independent assessment of battery usage and life.
So far the battery reminds me of my early days with my Nexus One -- before I had it rooted and optimized and undervolted. Once rooted and optimized, I saw a good 50% increase (at least in battery life).
If you'd like some relief right now (before we get it rooted), I recommend Juice Defender on the market. It turns off data (among other things) every now and then to save battery, and with this I can squeeze out 18+ hours with moderate usage.

how are you checking the percentage? when I looked in the settings menu, all I see is a long green battery bar, no actual numbers. Or are you all estimating from that?
I don't monitor my standby time, but I'm sitting at what looks like 40% after 13 hours of fairly moderate usage during the day, I'm impressed.

Ive been getting about 9 hours out of a full charge. Had to put my phone on the charger today at around 4 o clock because it was dead. I dont have much more info other than that. I will keep an eye on my processes over the next few days. I have only 3-4 cycles on the battery though.

To check the percentage of the battery life u have to download some battery widget in the market.. I.e smart battery monitor or battery percentage s.th like that...
Sent from my HTC Sensation Z710e using XDA App

You can also check battery level by opening Phone and dialing *#*#4636#*#* and then select Battery information.

I'm using Juice Defender and I have to say it really does the job : my Sensation lasts More than one day and a half (30min calling a day, texting, Android Market, Angry Birds...). Without the app running it would last a day (Angry Birds drains...).
Juice Defender says it is increasing battery to 1,53% and it is very close from reality.
I've been owning the phone from 24th of May.

Horrible battery life Verizon model

to be fair, my gf's verizon GS3 is ridiculously efficient. granted she was on wifi most of the day and doesn't use internet as much, but she was at 53% with 13 hours and 2 hours 14 min of screen time.
my att on the other hand, wifi off and on LTE, was at 53% with 6 hours and 2 hours of screen time.

to be fair, my gf's verizon GS3 is ridiculously efficient. granted she was on wifi most of the day and doesn't use internet as much, but she was at 53% with 13 hours and 2 hours 14 min of screen time.

But both of those are higher than 15% after 7 hours with 2 hours of screen time

How is the LTE signal in your area, if its not strong and swapping back and forth from 3g to LTE all day it can take a huge toll on your battery.

Try it without wifi and 4g. ONLY use 3g. I have a theory...

I'll do that tomorrow and get back to you

Mine seems to be doing great. The signal isn't that great in my house either. This is more real time use as I was asleep for a while. But when I woke up at 10am this morning it was at 92. I've been using it moderately ever since. I get about 8 hours with ridiculous use(4+hr screen on time).
Never on wifi.
Edit: I realize its kind of a bad example since it was in standby more than awake. But I'm getting great battery.

I had the same problem as you did. What made a significant change for me was changing amount of apps to keep running at 4 instead of default. Also I found the xda app runs in the background, continues to drain the battery. I have to manually kill the xda app every time I exit it. For today I'm at 12 hour running, and screen on 1.5hrs and 59 percent battery life.

right, and im saying my gf's VERIZON model spanked mine.

Give the battery sometime.

I've been getting worse battery on wifi than 4g for some reason. I also noticed my idle power usage is around 115mA, where on my thunderbolt it was around 20mA

Ditto on the xda app, it was burning up cpu cycles while in the background, enough to make my phone warm. So I just close it every time I'm done using it.

I have gps, wifi, data, and sync on still netting 27-30hrs battery life. The key is rooting and debloating....

Woh how are you getting your current draw? The apps that I've tried won't support the s3.

I have the Verizon model of the S3 as well. I have had it for over a week now because I was an early pre-order so I got it really early. For the first few days I was getting really bad battery life. I would maybe only get 8 - 9 hours with moderate usage, that being about 2 hours of screen time. I would play no games, and just browse the web and text. I am a big texter though, but on my DINC as long as I had mobile data switched off I could get plenty of life out of my phone. With this phone for some reason after about 70 percent, mine will start to drain much faster regardless of what I am using it for, even if the screen is is off. Just to test it I left all the radios on while the phone was at 100 percent over night, and the next morning it was at 96. The next day I tried the same test when my phone was at 50 percent battery, and when I woke up it was at 10 . I don't really understand what is going on here either. I keep seeing all of the reviews for the device even the Verizon version to point towards great battery life, but I am just not seeing it. Maybe rooting and a re-flashing the stock rom plus removing bloatware will help. I also got another battery just to see if that was the problem, but it doesn't seem to be. I'm hoping this is just a software issue, because I don't know why some can get such great battery and some can't. I would also hate to have to get a replacement phone.

im getting around 10 hours with Heavy use ... 6 hours of pandora, youtube, email, facebook, twitter, web
On day 6 with the phone
