What Gives?
With wifi on, cell radio, gps and bluetooth off, no notifications, no apps allowed to connect besides sipdroid, I get 30 hours standby on Captivate. Under the same conditions, I get over 250 hours with my iPhone 4...
This can't be a straight hardware issue, I'm at a loss to explain why android is unusable as a wifi-only softphone, while the i4 does the job perfectly.
Are you using a modified ROM? Most modified ROM's don't turn off wifi when sleeping, whereas the official OTA ROM's do.

Seriously? In a comparison test where you do not even use your $200 phone (with contract) you are concerned about battery consumption? Is it that hard to find a charger in 30 hours? What real world application are you trying to test?
On a side note my Escalade gets the same mpg as my civic hybrid when parked.

Odd....i get 20+ actually using the thing though i have noticed battery life is significantly better if you turn it off if you are not going to do anything with it but let it sit on the counter for days....also confirmed working on my evo. Perhaps i should look into developing this theory more
Music player testing
I spent $200 on this piece of junk, compared to my cassette player why is it that 2 years after I last used it it still plays but my captivate won't even power on?

Maybe it is not an android issue either. I have android phones in standby with cell radio off for 10 days. Maybe it is sipdroid - have you considered that?
haters gonna hate.
It's a phone, not an iPod.
granted, i love my captivate.. but i notice power drain when 'idle' with wifi on too.. if i recall, it seems to be more severe depending on the encryption.. (none vs WPA2 tkip+aes)
if im not actively using wifi i tend to turn it off to save juice.

You guys do know that you can set the wifi to sleep when the screen is off? The default is fifteen minutes but this can be modified as well.
Setting your wifi sleep policy to never should actually get you more battery life. A strong wifi connection is generally going to use less battery than a 3G data connection, especially if you have less than 4 bars reception. On the stock firmware with wifi sleep set to never I was getting 75+ hour battery life with light use. Basically I was getting 3 days with light use, 2 days with moderate use, and 1 full day with heavy use.
Homeboy's got to be on a leaked 2.2 build. On 2.1, I was getting nearly 4 days on wifi, and 3 days with minimal use on 3g, and that's with the wifi connection set to be always on.
The purpose is to have a wifi softphone
It's like splitting the difference between a cell phone and a landline. No contract! Free calls and sms!
When you factor in the savings from losing the contract, the phone (any phone...) pays for itself in less than a year.
Yes, I am on a leaked 2.2 rom. For some reason I assumed battery management would be better...
I need to revert back to stock eclair and test again!
Also, I think this iphone battery might need calibration. It took two full days to lose 20% and then lost 36% in 12 hours. So the results are a better but less shockingly so.
I'll update after a full calibration on the iphone battery and run on the captivate with stock eclair-

I'm catching your drift now.... If you don't find that flashing back to stock gives you acceptable battery life, try perception 8. Non uv/oc version. That's what I'm on now and it is amazing.
I know exactly what he's talking about. I had my captivate, and battery life was horrible on 2.1 and the leaked 2.2 build. I've had my iPhone 4 for about a week now, and the battery life is significantly better.
Geez, you guys get DAYS worth of usage out of it? I'm lucky to make it through the day! But I'm starting to think I'm just a heavier user. I have a very active Exchange account with Push, 4 more email accounts on 30 minute fetch, handful of widgets on 30 minute updates. WiFi always in use (thanks to the Y5 App), I use remote desktop/vnc a few times a day, and I do everything I can to keep it charged.
During the weekdays I'll get 15 hours of use, weekends I could possibly stretch it out to 24-30. Eh.....that's on Axura.
Was an I phone user. The hardware is great. I os is horrid. Too controlled, too limited. I would expect that you would get good battery life when the phone inhibits you from doing just about everything. Could never see myself going back unless they scrap the os and open it up.

The question is... why are you still reading the Captivate forum? If you were completely satisfied with the switch it seems like you would only be reading iPhone dev forums.

It actually should be a lot better in 2.2. My friend who owns an HTC Desire said his battery life increased by about 75% after the 2.2 update (though he may be exaggerating, who knows). The reason our battery life gets worse with the 2.2 roms is because they're all based off of unfinished leaked roms, which still have a lot of bugs and aren't completely optimized for our devices. I expect things to get significantly better once the official 2.2 rom is released or when/if we get a 2.3 port from the nexus s.
my captivate lasts more than 30 hours lol
my phone lasts 60+ hrs with light use and everything on. normal use and i get about 40.
So my friend who bought a captivate at the same time as mine (about 8 months ago) has been using stock rom (JF6) for a while. He basically just makes 10-15 mins call a day, checks weather and livescore sometimes, no background data, and he told me that he got at least 4 days!!! Right after he upgrade to the official Froyo, his battery life drops down, and he said not even lasts a day! I helped him install the Serendipity 6.3, told him to run for several days and recalibrate the battery. He reported back to me that with the same manner of using his phone, set the screen brightness to the lowest, his phone last from 6:00pm to 12:00pm the next day (about 18 hours). I then helped him to come back to JF6 yesterday afternoon and up to noon today, he said the battery doesn't change (means it drops less than 20%).
So does it means that in term of battery life, the JF6 gives us the best? What in Froyo makes it that bad in battery life? I might want to go back to JF6 to test. For now I'm using Phoenix Ultimate and got like 12 hours. Of course I use a lot of google voice, email syncs etc ...
I love Phoenix Ultimate. I made the switch to Phoenix Unleashed though. Much quicker. Man that is a great rom.

I agree with this statement
Hmm... I haven't really noticed a huge difference going from ROM to ROM. But I do know that on Andromeda3 in the 17 hours and 17 minutes since I unplugged my phone last night I've used 22% of my battery; this is with WiFi and the GPS enabled.

same here, I noticed that, I use completely stock eclair and official froyo rom, my cappy never tried to flash any rom, so I can only compare the stock eclair and official froyo's battery performance.
my eclair last for only about 18 to 22hrs, I'm a heavy user, after the froyo update, my battery can last up to max of 12hrs, that sucks!
Sent from my SAMSUNG-SGH-I897 using XDA App
I am on a custom ROM, and with 2-3 hours calls and 1-2 hour display with 3 accounts pushing in mails, I easily get past 48 hours.
i never found that to be the case. the battery life on eclair was fair but not great for me. i used the phone a bit heavier but found it to be similar to my iphone 3g or slightly less if it was being used most of the day. ok so i could get 4 days on the iphone but i really didn't use that phone much. the cappy even with light use wouldn't go more than 2, it used a bit more on standby than the iphone. every phone is different so i cant say that your friend doesn't get 4 days but in every day use i dont see froyo using much more battery on standby and probably uses less for me during use.
the best battery life on a rom i ever had was jk3 from the i9000m. it was perception something and was very light. the rom was also fast and feature packed. battery life was about 2.5 days on average. the next best was a tie between andromeda and the jh2 leak 2.1 with unhelpfuls kernel 1.4.1 and a lot of undervolting and the gpu underclocked for frequencies up to 600mhz and overclocked for 800-1200. that kernel ran great but was overshadowed by 2.2 with jit. i wish unhelpful would make a 2.2 version because his undervolt never suffered from charge death and the phone would tolerate much lower voltages. plus control over the gpu was a nice feature.
some of the 2.2 roms may eat a lot of power on standby but if the use is that light it should still get a day+ but i feel under use there isn't a difference i can detect consistently.
I don't like to get 4 days by just make phone call, because then why do you need a smart phone? I'm just wondering why that kind of thing happens? What in 2.2 eats battery that 2.1 doesn't? Ok, improvement in performance can shorten battery life, but should not be that whole difference (I mean from 4 days to 1 day)! That guy he even keeps all the crap wares from AT&T and doesn't have any task killer installed!

Really? I'm about the same usage as you and my Captivate cannot last longer than 18 hours...
Think again! I own TB since March and the battery is the worst thing i eva seen. Pls spare me all the tips abt charging the phone, i have tried themall. If i turn on lte, the phone will not last me more than 5 hours and it was not even heavy use. Please keep this in mind if u want to switch.
My gf has a charge I have a thunderbolt. Running a good Rom and kernel pretty much takes care if battery issues for me. I get about 2 hours more than hers with about the same usage. If you compare both using stock roms than yes the charge will last longer though.

Is she rooted and running a custom ROM as well, or are you comparing custom ROM to stock?
I'm giving up with running custom ROMs. Been there, done that. I just need a phone that works. Wait...there isn't one but really I just need a decent phone. I feel like I'm going down that road again using Android...ya know that Linux tinkering when Slackware was installing from floppies and the ego "I could do whatever I want" with it. Maybe I need to switch to the dark side for a break
If I switch to 3G on TB, I will have about 30% left by the end of the day. If I give the phone to my son so he could play a litto game or watch litto utube, I better have somewhere to charge the phone right away. It also depends on where you're at as far as LTE coverage goes. I think I have decent coverage (12mb/s dl; 2-3mb/s upload)
I'm confident that Samsung will release new firmware to address some of the issues. Don't think switching to a different phone, you won't have issue(s). For TB, I will seriously think twice as the known battery issue.

OP sounds like he needs to buy an iphone or a crackberry. Great battery life, no tinkering required.
I currently have active TB, Charge, Nexus S, iPhone 4.
Battery life - iP4 the best, then NS, then a total tossup on the TB/Charge.
Form Factor - NS the best, TB, Charge, iP4.
Screen/Display - Charge best, iP4, NS, TB horrible.
Call quality/coverage - VZW is great at both, AT&T is decent coverage, but call quality not top notch, T-Mobile terrible coverage, decent call quality.
The TB has a wonderful advantage, for my usage habits, over all the other VZW offerings in that it has the simultaneous voice/data over 3G. No other phone on VZW can do that yet.
A friend saw I had both phones on my desk yesterday; she asked about both since she wants a new one. She assumed the Charge was my favorite for some reason, but when she flat out asked I told her all things considered, the TB had a slight edge over the Charge.
I'd recommend either phone, but I'd also say they both must be rooted and tweaked to be of much use. The TB battery is much better on BAMF, but it still sucks, than stock, and the Charge is a laggy piece of cow dung if you leave it stock RFS file system.
I had the thunderbolt since launch day - and the one really, and only "killer" is svdo over 3g. Battery life killed me, as did the shoddy build quality (3 cln replacements in 3 weeks). The screen also was far far far too washed out in direct sunlight (didnt really noticed until summer, dang those grey New England days!). I ended up having VzW executive customer service swap my Bot for a new Charge - whilst my Thunderbolt would burn 15% mostly standby to 20% using the device on LTE or about 8-10% over 3g. I'm still a slave to wifi at home with the Charge, but at least the screen is usable outdoors and I can make it approximately 10 hours on 4g/18 forced to 3g/24+ on wifi. The LTE radio in all of these phones are the killers.
With that said, LTE speed overall really isnt needed, at least until video chat (or 2.3.4) is available and stable. I do really miss svdo over 3g from the bolt, thankfully Boston metro is blanketed in 4g, but I'm finding the Charge quite possibly the best overall 4G device on VzW especially after the debloat and voodoo mods.
OOB though with no modifications? Thunderbolt. If you can deal with the absolutely terrible battery life (on 4g) and are never out in the sun and need to see your display.
But the Charge's screen is superb, the phone is more comfortable to hold for an extended period of time, and battery life is head and shoulders better. I'm just scared that 2.3.4 will not make it on time, due to Samsung's terrible track record with updates and Skype with video will stall for Android on a whole.
Edit - I also absolutely hate TouchWiz. LauncherPro saved the day in that regard as well.
I had 1% battery drain overnight while the phone idled for 6 hours. I turned mobile data off at the time. 1%.
Right now the battery is at 75% and has been off of the charger for 12 hours and 17 minutes. The phone has been on constant 4G from ~6:45am until now, 12:41pm.
I love my battery life

Who said they weren't?
I just switched from a stock rooted TB to a Charge. My thoughts:
-Like everyone else, TB battery life was dismal in 4G areas. Even with the extended battery it was very poor.
-Screen on TB is *very* hard to see outside.
-TB pretty freaking heavy.
-HTC's Sense UI is a lot prettier than Samsung's UI.

How are you getting this kind of battery life. I'm running Gummycharged 1.7.5 with the PBJ OTC kernal (not overclocked though), and I lose 20% over eight hours while I'm sleeping.

As I said in the kernel thread, if you are going to stick with stock clock speeds, you will get better battery life on the non-OC version of my kernel.
I'm normally in a decent to strong 4G area, and I really don't see a huge difference in battery life between the TB and DC, but this week I've been working in a location that's 3G only, and in a building where the coverage is weak for data.
In this circumstance, the battery life between my Droid and my Thunderbolt is very dramatic. Whether it's just physically a better radio, or a better software for it, the Charge's battery life is amazing compared to the Thunderbolt's. This morning, after not even three hours, my Charge still had 90% battery life, my Thunderbolt was down to 48%. Neither phone had been used for anything; they were both just idle on my desk. Amazing.
The Charge clearly handles weak signals better than the TB in this area (Santa Clarita, CA - near Magic Mountain just north of Los Angeles).
I purchased the Droid Charge based on the Engadget review of the device. In particular, I wanted a device that could get on the LTE network AND have great battery life. This excerpt sold me:
When it comes to battery life, there's no competition. The Charge blitzed through a full day of what we'd consider typical use, coming off the charger at about 9am and not getting slotted back in again until 9pm the next night. Yes, you read that right, two working days of what we'd consider average use with GPS and WiFi on, taking pictures and videos, all powered by a single 1,600mAh battery. Granted, we weren't running our performance benchmarks at the time, but we were hammering the LTE antenna to get some speed results.
I expected to get, at a minimum, a full day's charge using LTE on this device, considering I live in an area where LTE isn't hard to come by (Los Angeles). Alas, I was sorely disappointed when my battery drained within 5 hours with minimal use. 5 hours!!! How can Engadget claim it will last for two days and that "there's no competition." It's totally misleading. The Droid Charge has a serious battery issue which nobody can seem to get to the bottom of. I even tried installing the latest Gingerbread rom to ameliorate the issue, but to no avail. Has anyone gotten a full day's use out of the device when on the LTE network?

I just got back from a full day's use on 4G with GPS on, WiFi on and Exchange and Gmail pushing mail as needed. I did not, however, text at all. One of my pages has an IP camera app that updates three feeds (snapshots) at least every five minutes. I am in a pretty consistent 4G area except when I'm at home (Philladelphia suburbs by my home is in a geographically challenged location)!
The phone just turned off as it dropped below 2% so I can't give any battery stats; I've been following the battery recalibration procedure listed here.
Keep the faith...you may not reach two days but you should be able to get a lot more than 5 hours!

Out of curiosity, which ROM are you using to get this kind of battery life? I just installed the latest Gingerbread leak and my phone is leaking battery at a rate of 15-20% per hour. I saw that re-calibration post, but I'm wondering if I can simply charge my phone to 100% and place the same ROM on top of the one I already installed. Just want to make sure I don't brick my phone.
Any thoughts?
If you wondering if you can just replace your current COM with the same one you are using by just replacing the files on the SD card then yes you can. If you're asking about re-flashing the same ROM over it again without wiping during the calibration then you can. It shouldn't harm anything.

I've already installed the latest Gingerbread ROM and updated all my apps and widgets on the device. Can I now charge the device to 100%, bump charge a couple of times (per the instructions in another post on the board), and then restart and wipe the battery stats in recovery mode? Or, do I have to charge to 100% and then completely reinstall the same exact ROM on top of the one I just installed?
Stockmoose.
5 hours? That's questionable that you only got 5 hours with minimal use. No Engadget did not lie, and until the 1700 mah phones are released the end of the month, there is no comparison.
Only with Altered Beast and heavy use was I able to kill the battery in under 8 hours. So I would chalk it up to a bad battery. Not everything is perfect.
Gingerbread is a leak, so trying to compare it to the stock rom does you no good.
You can wipe the battery cache without having to re-flash everything again.
Agreed, I was heavily influenced by the Engadget review and was seriously disappointed when I struggle to get a day's worth of usage out of the stock ROM on 4G.
The Gingerbread leaks have some serious battery issues. I reccomend flashing Humble v1.3 (Froyo) and undervolting. Best battery life by far. I can hammer the LTE radio for a few hours straight.
As a side note, all of Verizon's current 4G Android offerings have awful battery life due to having the dual CDMA and LTE radios. That being said, the Charge evidently has the best life out of the three of them. Future phones (when Verizon dumps CDMA altogether in favor of LTE) will have way better life.

Curious while running Humble v1.3 and undervolting which kernel are you running atm. And second what undervoltage settings are your using atm currently so yo uare getting random reboots. Reaosn I ask is I just flashed v1.3 this am and updated to Imnut's newest OC kernel but have left it alone right now without touching any voltage settings. So any input would be great and I'd like to set mine nad check it out to see if I can get even better battery life out of it. Thanks

This should help.
I get about 12 hours with minimal to moderate usage throughout the day 4G, wifi/gps off for the majority. I might have to try this bump charging, though. Would be incredible to get a solid day out of this thing.
9 hours of using my phone to check XDA post, playing bubble buster, and texting and my phone is at 77%. Only thing different on my phone is i'm using SetCPU to undervolt. But even with that. if you are only getting 6 hours with minor use. There is something wrong.
I just did a solid 36 hours by staying on my home Wifi almost the whole time. I'm using Gummy Charged 1.8. Before everyone starts calling bull----, I probably used the phone a total of 1 hour over that period of time.
Normally, it lasts 14-18 hours with only Exchange mail and an hour of gaming (no facebook, social networks, etc.)
If I recall correctly, battery life was an issue with the gingerbread leaks.
I did the battery charging cycles as mentioned above and erased the battery stats last night. Now I'm down to 20% after 6 hours of light use. That's pretty much the same way as before. What did I do wrong?

Not a chance I'll say bull**** that is for sure. When leaving the device on Wifi battery life will DRASTICALLY increase. The radio in the device is what is eating it up. If you want to conserve even more battery I've found and don't ask me why if you actually turn off Mobile data and then turn Wifi on it will help even more.
Ran a test last night and with over 7hrs on Wifi it dropped on 5%

I just did a solid 36 hours by staying on my home Wifi almost the whole time. I'm using Gummy Charged 1.8. Before everyone starts calling bull----, I probably used the phone a total of 1 hour over that period of time.
Normally, it lasts 14-18 hours with only Exchange mail and an hour of gaming (no facebook, social networks, etc.)
If I recall correctly, battery life was an issue with the gingerbread leaks.

I've gotten 24 hours with about 20% to spare going in and out of Wifi and 4G. I had 3 gmail accounts sync'd to the phone and I probably streamed about 20 minutes worth of music using Google Music. But, I probably used the phone for a combined total of 1.5 hours over that period, and it was a slow day, so I actually didn't get many emails.
I think I was using one of the Froyo Gummy ROMs.
I don't think it's very fair to use custom ROMs and then complain about battery life. Was your battery life lower than 5 hours on the stock ROM? Did you even use the stock ROM?

Try reading more than skimming the OP. He implied that he started stock there, and about 3 posts down said that it was ridiculous that even the stock ROM couldn't get 5 hours.

My apologies, I misread his second to last sentence in the OP.
Either way, 5 hours is not normal and I wouldn't blame the Charge just yet. Not sure if you guys have official 2.3 yet (I'm a Thunderbolt owner myself), but I know the Froyo ROMs on the TB have a very noticeable increase in battery life compared to the Gingerbread leak builds.
I get about 6-8 hours of heavy use on my 2.3 ROM on the TB. Probably closer to 13+ with Froyo.
Hello All,
Hoping to get some advice. I bought the official i9020a from best buy yesterday (on launch day) seems to be a great phone but I have a few questions and problems.
I unlocked the bootloader but did not root it yet
The biggest issue is battery life. Its terrible (like nexus one before applying the wifi setting trick after 2.3.4 terrible). this NS loses almost 10% of its battery power per hour on standby.
While on standby I have the following running
-wifi turned on
-3 push gmail accounts
Also I noticed that the hotspot doesn't work. when i turn it on it briefly shows 3G and the signal strength bars in green but then the 3G icon goes away and the signal bars turn white, my tablet and laptop can connect but no internet from connected devices and the phone browser itself - just page's not found
my baseband is: i9020aucke1
kernel version: 2.6.35.7-ge382d80
adroid-build 'at' apa28 #1
Build Number: GTJ61
Any advice on the above would be great, I can easily return it but would rather keep it.
Anyone else buy the official Best Buy version and having issues?
Also Anyone know if this phone is locked to AT&T? I don't have handy access to a t-mobile sim card.
Thanks in advance!
Flash new rom. I am sure ATT has some tethering lock on the build. That should be expected.

10% / hr is unbelievably bad (assuming the display isn't constantly on). What's consuming the battery in the battery stats?
Thus far no subsidized Nexus device has ever been sold sim locked (The Vodafone Nexus One, T-Mobile N1 and NS and the various Canadian Nexus devices). I'd be surprised if it were sim locked.
Thanks everyone for the tips. After my original post and now I finished the root and installed cm7.
Cm7 took care of the hotspot issue. Battery life is still pretty dismal in standby. Ill do a test tonight and leave it unplugged all night and post what used the battery the most in the morning.
Thanks again

no man, something is really wrong with your device. My phone loses ~1% in each 4hrs in stand-by (during the night).... I can easily stay 2 days with one single charge (with light use) and with everything ON!
edit: oh, and btw, you won't find better battery in any rom out there. stock rom with stock kernel is the best so far (regarding battery life)... i really tried every single combo and it's the main reason i'm back to stock after so many time (with several devices) using cyanogen. with cm7 i use to lose 1~2% per hour in stand-by!
edit2: you should make some complete battery cycles. Battery life in the first week is not really great, but not that bad anyway!
I think there is something pretty wrong with it
a little over 4 hours last night unplugged in standby/locked
start power: 75%
end power: 35%
most used
display 64%
android system 6%
cell standby 6%
Everything else was system stuff at 1%
Display seems to be the culprit in standby.
Hardware? If so I can easily exchange the phone
Thanks again for the advice
I bought the T-Mobile version back in April. I found that my battery life on day 10 was about TWICE what it was on days 1, 2, 3.... I guess the battery adjusted as it got used some.
I suggest you give it two weeks and then note your battery life again.

I have seen the "battery gets better over time" statements quite a bit on XDA and other forums. I'll give it a week or two and some cycles.
I have to say the "it gets better" is not something i have ever encountered on any smartphone or dumb phone i have ever had though?
Anyone also getting really really slow charging during the 1st week?

If you previously had a non samsung device it charges *slow* even on a 1A charger. No way around that.

thank you! yes - i should have probably mentioned that this is my 1st samsung smartphone.
Yes, it charges really slow and it wont be better. Takes about 3,5hrs to a complete charge.
Battery really gets better after 2 weeks, but even in day 1, never was so bad as you described.

Fixed!
Ended up returning to best buy swapping the phone. the new unit straight away showed normal discharge during stand by and normal battery when in use.
In the end a bad phone.
Thanks to all for the above responses!
ya you definitely had a bad dud...i was lucky in enough to get a good "dud". with approx. of 3 hours of display on, background syncing, and other moderately intensive tasks i was at a point where i was going on 1 day 12 hours 16 mins and still had 40% of battery left.
