Conditioned the battery gauge, bought a new charger from Amazon, and I've been very happy with the performance over the past 5 or 6 weeks. With my regular phone usage pattern, the battery lasts a couple of days.
That all changed this past weekend and I couldn't figure out why. I had taken a 500 mile roundtrip (GPS worked perfectly, fyi) with the phone plugged in to a car charger and all I could guess was that it somehow messed up my battery. I had installed one other application, but the battery stats didn't show any unusual behavior or partial wake usage, and the problem persisted after I uninstalled that app.
Then it hit me that I had changed one other thing: I had purchased a 32GB SanDisk microSD card from Verizon and the travel weekend was the first time that I had left it in the phone continuously.
I have experimented over the past few days and it is clear: my battery lasts for a significant time without the microSD card, while it drains ridiculously quickly (with no phone usage) if the microSD card is in. The comparison is like night and day. Two days of regular phone usage without an external microSD card installed, compared to less than a day of minimal phone usage with an external microSD card installed.
Has anyone else experienced this? Anyone else using the 32GB SanDisk from Verizon? Either way, which brand/capacity cards are other people using? I am not even certain which company I should report this to!
(Captivate on AT&T with the stock firmware)
I have an 8GB SanDisk card. I have not tried without the card, but I get one to two days of regular usage with it in.
Using an 8GB Trancend class 6 card and get great battery life.
In the past Samsung has had issues with SD cards killing battery life if you set things like the camera to store your pics on it. I had a eternity and if I set the phone to store pics on my SD card the battery would be dead in 4-5 hours, store pics on the phone and the battery lasts a week.
So I guess this would not be unheard of with Samsung phones.
Thank you, Pmac25, that perfectly describes my situation.
I had it set to store/record photos and video to the external microSD card on Saturday and I didn't change it back to the internal card when I was finished.
If I leave the Camera set to store things on the internal card and just use the external for previously stored music/movies, will it have the same effect on the battery?
Cheers for pointing out the issue, much obliged.
I have a 32GB SDcard installed. I only store older data on that card and I get 2 days on one charge.
Pmac25, does your observation also apply to storing/listening to music on the SD card?

I have noticed that running video/music from the external SD kills like 1% of battery life every 5 minues on my phone!. After making this observation, i moved some commonly used stuff to the internal sd and have not noticed such a drastic reduction in juice.

well this sucks..!! I have all my music and videos stored on external SD card so that they are portable I can just take sd card and all my music n vids are there...but now it seems I will have to transfer all my stuff on internal storage. But then whats the use of having external card when it drains a lot more battery. company like samsung should have fixed this issue long time ago.

1% every 5 minutes would equate to 500 minutes of continuous use (8.3 hours). I guess it depends how much of your mix is video and how much was audio.
The hardest part of any battery test is determining if anything else has been left running in the background between tests.
I have all my music and movies on the external card, but I record pics and video to my internal card.
I am not to sure about storing/listening to music off the SD Card. Like I said the Eternity has this issue and I have not really checked to see if the Captivate had it or not.
I have music and a couple movies on my Ext. SD Card and right now I have the camera set to store there as well. I guess I should run a test and see if the SD Card issue is still there.
If I remember right on the Eternity the bigger the SD Card the faster if drained the battery.
Ok now you guys got me thinking. Is the battery issues with the Cappy the same as with the Eternity.
I will see if I can find the thread on the Eternity board about the issue.
Did some more testing.
Empty external 32GB microSD card installed. Camera app set to store on the internal card, so nothing was "touching" the external card.
Battery drain was still substantially higher than I normally experience; test was run with almost no regular phone use today (a few texts and a few mins of phone calls). It isn't quite as bad as when I had the camera app set to store on the external card, but still a far cry from my battery performance with no external card installed and much higher actual phone usage (with the phone in the same location, with the same wireless connection, every other variable I can think of the same).
I did a quick test. Pulled out my 4GB SD card and waited 2 days to see what would happen. With normal use, my phone lasted about 12 hours longer (about 1.5 days) without the card. Put the card back in and my phone barely last 20 hours. I'm leaving the card out for now.
Incredible how the card has that much of a drain on the battery.
Ski
Very interesting
Very intersting, wish more people would jump in on this. Doing test myself, but this may explain my battery issues. Seems thats about the time it started draining faster is when installed my 16GB micro.
Are there any cases for the Captivate that have a microSD card holder? That would be really convenient; I have a 32gb card as well.
A firmware bug could potentially cause this extra battery drain when microSD is not in use. Did you guys that notice the battery issue with SD card all still running stock JF6 firmware?

May be you are right. I am running stock firmware. I hope samsung will fix this issue with froyo update. I guess we can suggest these changes on twitter or something. that is what I read some where that you can reach samsung & suggest then some thing on twitter they were very active ob twitter promoting this galaxy series.

I left my phone off the charger last night for 7 hours. With 16GB microSD card in and cameras are always set to save to external microSD card as well all my podcasts and movies are on the SD card as well. GMail sync, weather sync (every 3 hours) are both on. My phone battery dropped only 5%. And I'm running latest JH7 firmware. So, it is safe to say there is no battery drain on external SD card in JH7 firmware.
I'd love to try running this with no SD, but my lag fix is there... Ugh, I wonder if it worked be worth the experiment.
Sent from my SAMSUNG-SGH-I897 using XDA App
If your lag fix partition is on your external SD card, you will no doubt add extra battery drain to your phone because your external SD card will be accessed a lot while your phone is on.
I haven't seen these concerns mentioned anywhere else, so I'm sorry if it's a duplicate.
I updated to KB1 on the 24th. Yesterday & today, I have noticed unusual battery drain. The battery manager says that my screen has drained 83% of my battery (my battery total is 41%) from a 100% charge. My phone has been on for 7 1/2 hours and the display has bren on for 1 hour, 16 minutes. This just seems like an unusually high amount of drain compared to JH1. Do I need to let the battery stats reset after the update by draining the battery and charging it a few times?
Second issue... Whenever I was using my phone, the back was getting VERY toasty near the SIM and SD slots. I ejected my external SD and the heat has not returned. The same SD card has been used for several months with JH1. Anyone else experiencing this issue?
Sent from my Samsung Captivate
Can't say as I have noticed any heat but I can relate about the display using a high percentage of battery on the phone. I am also typically not showing anything else using the battery other than idle, standby, voice calls, and Wi-Fi. Now for example I am at 10 hours of use, have 62% battery left, and was using the music player for a while at work, updated and downloaded apps from the marketplace, shot some HD video and stills, sent some texts, checked some FB, did some GPS tests, etc. I don't know if 2.2 stock is just very efficient (went about 36 hours before charging and still had over 25% left this morning) and so the only thing using the battery is the display but it seems like it just isn't reporting everything to me. Maybe a few more days of use, a full drain or two, etc and it might start reporting correctly if it isn't already.
Battery is normal, I have noticed some heat though...even went as far as to turn my phone off for an hour today because of it.
I thought it was just me, but I noticed batt drain too

Yeah, I am starting to think the official 2.2 is a major flop. I had high hopes, but so far it just hasn't delivered to my expectations.

I also feel like it isn't telling me everything that is using battery. Since the update, I'm only seeing Display (always on top), wi-fi, and cell standby.
To add to the SD heat issue, the media scanner has been running for about 5 minutes now and still says that 0% has been scanned in the notification bar.

I can't say I have had any issues with the media scanner taking an unusual amount of time. I have over 1000 songs, about 6 full length movies, photos, music videos, etc, and I can't say it ever runs more than about 20 seconds or so.
Just plugged my phone in and didn't notice any heat, but was still only showing display, wifi, standby, voice calls, and idle. Battery life itself though is still good (at least good enough for me - 24 hours + on a single charge with moderate use). I have been stock since I bought the phone back in August.

Go into MyFiles and delete your Android folder then reboot. Sometimes the media scanner freezes due to the cache in the Android folder.
I've also been having a lot of battery issues. Twice today my phone died within 2 hours of being off the charger. The first time was 1 hour and 15 minutes with sending and receiving 2 texts. The second time was 1 hour and 45 minutes, no texts. I didn't have GPS, Wifi, or Bluetooth on and didn't use the phone except for those texts. I used to get a full 14 hours + out of my phone before updating to froyo!

Is there any sort of side-effect when deleting that cache folder? The scanner also hasn't been running since a reboot so that may have been a fluke.

I also am experiencing terrible battery life. On jh1 with heavy use I would have to put the phone on the charger which was expected but it would be fine for the rest of the day without any problem. Now I'm having to live off of a charger. I haven't experienced heat issues but I haven't had my SD card in either.
Another issue I've been wondering about other people having is sending MMS. Before the update I done this without any problems at all, now I am very lucky to send one. I read somewhere that the MMS limit was actually smaller after the update, though I have no proof of this. I was just trying to send a couple 2-4 second audio clips that can't be larger than a few KB.
I had a Droid Incredible before this and was root doing everything under the sun with it, when I got this phone I didn't feel the need as much. This update has proved me wrong and I will be jumping on a custom ROM real quick like.

I decided to completely drain my battery. It died after 2 hours of screen use (over the day) with texting, web browsing, a check-in or two on Foursquare & Gowalla (no GPS,) and a little gaming. Display, Wi-fi, & Cell Standby were the only listed items for battery drain. I don't understand!
I just bought a Captivate and updated to 2.2. I also have a quick drainging battery issue. Are the phones defective or are all of them likes this ?

Main one for me at the moment is you cant move apps/games and their data to the external sd card on a unrooted phone ,they will only work if on the internal sd card which is only 8gb,once that is used up (which doesnt take much ) then you cant install any more games unless you delete an old game.

In 2D mode the battery lasts over a day with normal talking and browsing + e-mail. With 3D the battery goes down fast. Of course we are all playing a lot with our new toys so several hours is pretty OK for a beginning

I think this will be quickly sorted. However, I'm putting all my photos/videos/music etc. onto the "external" card and some stuff (iGO8) seems quite happy to run with the data files on the external card. I actually installed this (as an .apk file) from the external card, It might be an idea to try this with others.

Yes i also have moved 3d movies,photos to the external sd card they seem to work well from there,but i did install a GPS navigation program which was a apk file from the external sd card,but once i installed it,it then downloaded the maps and other data to the internal sd card and would only work afterwards from there,tried moving the maps to the external sd card but no good.
I charged ny battery til its tells u its fully charged. Then powered it off then unplugged then plugged back in. Once offscreen battery indicator shows the battery fully green unplugged then powered on. Once phone is on i plugged power cabke back in. Once phone tells u is fully charged i repeat the steps a couple more times. Then i boot into clock work recovery and delete battery cache. Then use ur phone until battery is totally drained. And thats it. Before my phone would last barely 6-7 hrs. Now it lasts me all day, with some 2d gaming, 3d gaming, texting, web surfing, google +ing, fbing..etc.

Hiya,
Did anyone notice that the proximity sensor takes few seconds to deactivate?
I sent an email to LG and this is what they replied to me:
“We are not aware of this issue with the proximity sensor taking a few seconds to deactivate itself. We recommend to book it in for repair with ourselves if the issue progresses to an more severe level. This can be done by contacting ourselves on 0844 8475454.”
Does anyone have this “problem” as well?
Cheers,
In an attempt to tame mediaserver wake locks I copied all music and pictures to internal storage, then removed my sd card.
Mediaserver used to keep my phone awake for an average of 30 minutes a day. Now it's showing about 1 minute total.
My average battery life also changed from 24 hours to 48!?
My sd card was a pny class 10 16 gb, I tried exfat and fat32 and different allocations sizes before just removing it completely.
I really changed nothing else on my phone. It is possible the way the s3 handles sd cards is severely flawed.
Try it and let us know your results!
I'd also like to note that my s3 killed a new class 10 SanDisk in about a month.

Those pictures don't seem anywhere near right. Your screen was on for 3 hours and the cell standby took almost 4x the juice that 3 hours of screen would(therefor like 11-12 hours of screen time, 14-15 total) and you got over 36 hours out of your battery?
Somethin ain't right with that. Or do you have the extended battery?
I have the stock battery. I have always had really good battery life with my phone.
Sent from my SCH-I535 using xda app-developers app
I don't know how you got 36 hours of battery life with as much juice as the screen and cell standby took...not to mention the rest of the apps. It just doesn't make any sense.
I'm running probably one of the best ROM's for battery life, CM10 Official, and if I don't use my WiFi tether I can get about a full day with moderate use. Screen time roughly 2 hours +/- half an hour depending on what I'm doing. And that's staying in a 4g area where my phone isn't searching for towers or anything.
Cell standby on some roms is "calculated" wrong and appears to eat way more battery than it does. It is a glitch in the system and should generally be ignored. First couple ROMs I ran cell standby was always top of my list. Now it never is, and I do nothing different, just running a different ROM.

I am running stock ics VRALF2 odexed and rooted. I also have lean kernel 0.9 installed which is undervolted so that definitely helps with battery but I was running that before I took the card out.
The radio showing as taking so much power is because Samsung accidentally has it set as taking up 39 milivolts rather than what it should be, 3.9. The error doesn't affect your battery life at all, it just gives the battery app the wrong info. There is a fix for it in the Android dev forum for our phone but I think you have to be rooted to do it.

I get much better battery life on AOKP than I ever did with TW.
This is all good info. Let's try to stay on topic though. Anyone try removing SD card?
I am still netting huge battery gains. I will post gsam graphs and stock battery graphs soon.
Oh and my mediaserver wakelock stay awake time was 30 minutes yesterday but still same battery life.
Maybe our phones use a lot of power scanning for media on an SD card. SD cards are MUCH slower than the internal storage. Or maybe the s3 supplies too much power to the SD card resulting in battery issues and the "is your s3 killing your SD card?" thread.
The sandisk that died on me was a 30 mb/s version. I use those on my Nikon D90 with microsd plugged into an adapter, whichever is on sale SD or micro. Those have lasted me thousands of pictures and at least 2 years, and still are not dead.
It may be a good idea to rig up a multimeter to the power contact on our microSD cards and make notes of the max and average voltage during normal every day use. We would also need an entirely different phone to compare it to. Different manufacturer mainly. But still ICS.
Is it possible to change SD card supplied voltage in a kernel?
Again, let's please stay on topic and not turn this into a what ROM is better thread.
Thanks all!

It's not fat32.Thought bout it but havnt gotten around to it.Would just be for CWM anyway.Allocation size, ya got me there, guess whatever default is cuz I never tweaked or partitioned anything when I formatted.Tried a SanDisk initially but wouldn't mount right.That's why I just kicked extra cpl bucks for Samsung card.Sounds like it paid off in more ways than 1.Forgot what size your card was but I think the bigger the more juice it uses up.Sorry not much help other than go the Sammy route.

I've bought the international version of the S7 (the only one available here in Portugal) which is the SM-930F on the last tuestday (2016-09-16).
During the wednesday, I've noticed that the battery drained really fast, but I thought that it was because of the whole first-day configuration / installing 50 apps thing.
On thursday (yesterday), I removed it from the charger at 8h30, barely used it, and at around 13h00 it had 44% battery. I don't have a lot of background syncing or anything like that, just the normal I've used on other phones before the S7.
I've read somewhere from people that had similar problems and they said a factory reset solved. I did a factory reset but the battery kept draining at the same rate.
So, at around 20h30 I went to the store and asked for a replacement. Exactly the same model and color.
I went home, installed all apps and updated everything so I could test it today without updates and downloads. I didn't restore any settings from previous installations.
Today I took it off from the charger again at around 9h00, it's 14h30 and it has 64% and I barely touched it! I've checked some stuff at lunch time for like 10min, that's all.
What can possibly be wrong here? Everyone on the internet says that this phone's battery life is one of the best out there, but it's draining faster than any of my previous phones!
Both the original and replacement phones were sealed in the box.
Any ideas?

I've read somewhere from people that had similar problems and they said a factory reset solved. I did a factory reset but the battery kept draining at the same rate.
So, at around 20h30 I went to the store and asked for a replacement. Exactly the same model and color.
I went home, installed all apps and updated everything so I could test it today without updates and downloads. I didn't restore any settings from previous installations.
Today I took it off from the charger again at around 9h00, it's 14h30 and it has 64% and I barely touched it! I've checked some stuff at lunch time for like 10min, that's all.
What can possibly be wrong here? Everyone on the internet says that this phone's battery life is one of the best out there, but it's draining faster than any of my previous phones!
Both the original and replacement phones were sealed in the box.
Any ideas?

Hi
Most of times battery consumption is due to settings , WIFI , e-mail sync , location , rogue app , facebook..... review them......maybe do a factory reset , install nothing and see how it behaves , install app in smaller lots to see if there an increase on battery drainage , if you where root there is an app that is great to see exactly who is the culprit

If it was a rogue app, wouldn't that show up in battery usage?
For apps, syncing, location and network, I have the exact same settings I had in my previous Note 4 and LG G2, and nothing like this ever happened.
Location is on all the time, I'm connected to my company's WiFi, 4G always on (overriden by the WiFi most of the time).
The only thing I didn't have in those phones was the "screen always on" of the S7 that shows the time, which reviewers say that it's so optimized that it barely makes a difference.
I wouldn't be complaining if it were draining a bit faster than the Note 4 or the old LG G2, but it's actually draining like 4-5 times faster!
Yesterday I had both the G2 and the S7 with me, with all the same apps, with a SIM card from the same network/account.
When I reached the store, the S7 had almost critical battery, while the G2 had around 80%...
The S7 didn't get hot or anything.
I will wait a couple days to see if it improves, but it's extremely disappointing, after spending 730€ on a new phone (around $820).

Battery drainage is a Bit** , some time is hard to find out what is going on and you need to be patient and methodical
to your questions

Not necessary , may be is a process and do not show in there , most times you need a better app (BBS the link i gave you) and be root to see those process , or by discarding apps to find out
For apps, syncing, location and network, I have the exact same settings I had in my previous Note 4 and LG G2, and nothing like this ever happened.
Different phones , not necessarily the apps behave the same in different phones
Location is on all the time, I'm connected to my company's WiFi, 4G always on (overriden by the WiFi most of the time).
Try different settings and see if they make a difference , see what apps are using location , do not have wifi on all the time during sleep......
In my case i do not have even half of that drainage , of course we all use the phone in different ways and have different apps......as i said is a royal pain in the a** and need to be patient and methodical to find out if is a real hardware problem or a configuration problem
After reading this,
https://www.reddit.com/r/GalaxyS7/c..._s7_edge_battery_drains_20_overnight_8_hours/
I've decided to wait for a few days to see if it improves. The poster seemed to have the same problem I have and he said it stabilized after a few days.
If he problem persists, I will try the things you said.
Thank you.
Maybe you can install Better Battery Stats and wait for it to give you some answers.
I would suspect that the phone has trouble connecting to network, WiFi or mobile network or tries to constantly fix to gps signals. A constant search for better connection results problems like yours. If you can, try another operator sim for a day, or try another location.
Perhaps do not use wifi for a day to rule out bad compatibility with your routers settings.
My S7 SM-930F do not lose ever one percent per hour if left unused with everything on and no powersaving.
Did you use Memory card ? I had similar issue on S4. There was damaged file and phone tried read it whole time.
I had the similar problem which was caused by Email App. Try to install Wakelock Detector Lite and see which app drains the battery most. In my case, Email app was preventing phone to enter deep sleep mode and it can not be seen in Android battery statistics.
Wakelock Detector does not need root but you need to enable developer mode and use adb shell. Code is below, you can Google it for how to.
Code:
"adb -d shell pm grant com.uzumapps.wakelockdetector.noroot android.permission.BATTERY_STATS"
Here's an update:
So I've waited a couple days and the battery seems perfect now. I've unplugged it yesterday at around 12h30, used 9gag, browser, facebook, youtube, gmail (a bit of everything, actually) and now it's almost 10h00 and it still has 44%.
I've installed that GSam app and it seems that the phone was transferring lots of stuff through WiFi in the first 2 days, I assume that was the cause.
Thanks everyone for the tips!

Thank you for reporting back on how this went for you! Not everyone is so good at doing us this favour!
A lot is going on with a newly initiated mobile and perhaps it was a new firmware too that was downloading in the first days and together with everything else the battery life seems terrible to start with. My S7 downloaded a new firmware and flashed it in my first few hours with the phone and I didn’t notice before it wanted to reboot to flash. Together with all other updating going on if you reinstall apps and set things up it takes a while for the poor thing to settle!
The switching of phones did of course make the whole process start from scratch again and this made the problem seem even worse to you!
Well, Samsung should put some kind of warning in the box or something, I was getting extremely disappointed. I'm very happy now though, the phone seems to be amazing.
