I know that there are lots of these battery life threads and i have read most of them and I've tried closing processes that i don't need and i have tried setcpu to keep the cpu low when the device is off, which seemed to help some but my phone would shutoff randomly. So last night i had a full battery and went to bed when i woke up 8 hrs later i was at 20% so about 10% an hr not even using the device. I have attached some pics for reference does anyone have any thoughts that might help. Thanks
I don't know about galaxy S but on my X10 the problem was wifi.
When I didn't have a data plan I had wifi on all day and the battery was down in 10h max 12h.
To improve it I had to use JuiceDefender to enable wifi every five minutes for updates..
Try to disable wifi overnight, reboot the phone and see what happens.
By the way, what app you used for those stats?

I don't have wifi enabled, I don't use it that often. the name of the prog is system panel
Very weird indeed. I have my Captivate with Wifi on all day, GPS signal and auto sync and when I go to bed and wake up, the battery hasnt gone down at all. I had the phone go on full battery one day and I even sent a few texts and went online for 10 minutes before it lost just a bit of battery.
Do you have that one LED app installed? The one that shows a little red dot on the corner of your screen when you have a notification?

yes i do.. Why? but it was turned off last night, as its turned off every night
Ok so i tested again last night and I did not have my im+ app running and the battery life was soooo much better. I also did not have system panel running which records all the battery and cpu stats but i'm think its the im+ app that was taking up all the juice. Can anyone think of another app that does skype and facebook but that also does not take up sooo much batter life??? Thanks

Open up the dialer and type in *#*#4636#*#*
Go to BATTERY HISTORY>PARTIAL WAKE USAGE and maybe that will show you which app is sucking up your battery life while you sleep.
Also try, if you don't absolutely need an internet connection while you sleep, SMODA widget to turn off your mobile internet. It's quick, free, and painless.

I have never seen such good battery life on a smart phone.
I could easily get 2 days, but i rather charge every night and then not worry about battery usage.
The wifi/gmail/gps made a big difference, its too bad you can't set gmail to hourly or something lik e that. Some of my email accounts i would like to set longer than hourly.
The last few days have been pretty good one my phone. Used to get maybe 16 hours but my last charge lasted me about 50 hours with moderate browsing, gaming, and voice/text. Juiceplotter is telling me I'll be getting about 47 hours

How many hours with the display on?
Sent from my phone so I apologize for any spelling mistakes
My battery icon depletes one notch when I'm using the screen for about an hour. Some people recommend cycling the battery, in which you do a full drain and immediate full charge, 3 or 4 times. I've done it, but it's hard to say if it explains my good battery life.
let the battery drain COMPLETELY until the phone turns off a couple times, then charge it till 100% without unplugging it.

You don't want to drain the battery that much, those kind of batteries can be damaged. The phone turns off for a reason.
I haven't done the cycle thing and its fine. A lot of that comes from older batteries with the memory problem.
irus, software which is based on data connection drains the battery one way or another. Some apps now support push notifications and IM+ does too. Did you try to use push?
These claims of multiple day charges with moderate use is crazy to me. I have the newest ROM, a black screen, display all the way down, gps off, wifi on when in range, make zero voice calls, run juice, and only have 2 widgets that update every 4 hours. I use my phone for a maximum of 3 hours browsing the web, reading XDA and feedR, checking facebook and the occasional text message. My phone lasts a total of 12 to 14 hours. My battery has a manufacture date of late July. Is there some secret I am not aware of?

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.

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.
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.

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

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

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.
CM7 nightly+ Faux's kernel + SetCpu + Juice Defender = 8-9 hour battery life. I have tried EVERYTHING!!! I cannot make my phone last longer than 9 hours. What am I doing wrong? I'll take all suggestions....

Doing it wrong.
EB 2.3.5 + Trinity kernel
Charge your phone before sleeping. Leave it idle while you sleep, unplugged. If the battery stills drains you have an issue. If connected to wifi - shouldn't take more than 20% off your battery. If you have a weak signal, it could drain your battery.
Sounds like you're just always on the phone. Buy an extended battery. $10 on ebay from hong kong.
With moderate usage, in GREAT signal areas and/or wifi I can last 20+ hours. With poor coverage (where I work) I can't go more than 5 or so. The radio seems to eat the battery unless you have a strong connection.
set screen brightness to 25% unless you really need it. set a profile for 312 max/216 min screen off on setcpu. turn off auto sync. use your power control toggles. shut things off when you're not using them. basic smart phone theory. my battery drops 1% every 2.5 hrs. when idle. fwiw, i'm using the stock tweaked rom with updated baseband.
MIUI + Stock kernel = 20 hrs.
....
Uninstall the task killer....its not necessary. That could be eating ur battery. Im a fairly heavy user and i easily get 12 hrs on average.....mainly texting and browsing. I dont make many phone calls

I use this phone mainly for phone calls How crazy does that sound? I get awesome battery life. I'm running stock 2.3.3 and juice defender beta 3.5.9 and I get 14 hours on moderate use. I talk about 2-2.5 hours, send 30 texts, send 3-5 emails, browse for 1 hour, stream music for 1 hour, browse the market for 15-25 minutes, and occasionally play some tegra games (no more than 20 minutes, but this eats the battery up the most).
If you want more battery life, there is a 3500mah battery with a custom cover that should keep you going a full 24hours, its cheap too, but a little bulky. They are talking about it in the accessories section.
I can do 2.5 hours of gaming or 3 hours of browsing, to go from 100% to forced-shut-down. I find setcpu made it worse during idle times. I was using faux uv/oc and I realized performace was noticibly the same when I forced it down to 700mhz, so I did. But, during standby, when before at stock speeds with custom kernel I got 2-3%/hr drain, it was draining upwards of 10% per hour with the speed forced down in setcpu. This is all with the home screen as the open app during standby.
You will find that keeping google maps open (GPS off) during standby leads to a 5-10%/hr drain even though the phone should be doing the exact same thing with the app during standby as the home screen; nothing at all.
I will use the phone sparingly and I had it run out during my work day a few days ago, very embarrassing. I listened to less than 1 hour of music, browsed 30 minutes, used maps with no gps as that is broken anyway for a total of 30 minutes, texted about 40 in/out messages, and talked 20 minutes over 6 phone calls or so. I'll warranty it for the broken gps. Hopefully there are new G2x's out by now and I'll get a new revision or something.
