battery/charging problem.

i'm using donut's android build and this battery/charging problem is driving me nuts. my battery lasts 4-5 hours max and the weird thing is it only takes 10 -15 mins to show my battery is fully charged. i tried flashing again, left the phone until it dies by itself and charge it, left it being charged over night but none of them helps. anyone having same issue? i know with android on our vogue the battery life sux but is it this bad??

might be time for a new battery. It should take 30 to 45 mins to charge. And it should last longer than that. How much time do you spend playing games ect. Gps also is a battery drainer. Also alot of data usage.

My battery can last all or most of the day with moderate use on Android.
If you are running off an SD card, try booting back into windows for a day or so to see if you have a similar battery problem there too. Actually, windows battery life was MUCH worse for me. The difference is that Android does not wake the screen for Calendar alerts or text messages like WinMo does... though in Android you do still get the vibrate or sound alert.

win mo is actually quite ROM dependent (NFSFAN's ROMs got awesome battery life). android is pretty kernel dependent. if you are charging overnight, and using latest zimage/kernel, and turing off syncing (background data), and that is the battery life you are getting, you need a new battery.

i use gps a lot as i work as a field technician but i don't have gps turned on all the time while im driving as the screen shuts off by itself in a minute or so. maybe gps is still working even with the screen shut off? and it's a nand install so trying with winmo is not possible. i had much better battery life with winmo for sure. if i turn off the syncing will i still be able to use gps?

Which NBH are you using? The newest ones are way better than the older ones. If your using a current one check out tatnai's FAQ... http://forum.xda-developers.com/showpost.php?p=5599516&postcount=33

It's the kernel. you know the file you rename RUU_signed and you flash.

I am definitely having this problem as well, and the charge does not last very long it seems either. Was much, MUCH better in the Windows Mobile builds I was using previously.
I am on Bell using the basic HTC Touch

Same problem here. Brand new battery on bell.

Yeah, although battery life is positively improved and pretty decent now, there is definitely still something funky going on with charging. I still don't rely on / believe when the phone says it is fully charged. It happens too quickly to be possibly true.

I have the exact same issue and it is absolutely a problem with charging within Android. I have two identical batteries. One was fully charged in winmo before I flashed - I took it out and swapped for the other one. Flashed it with that battery in and charged it overnight. It only lasted about a half-day. Came home and swapped out for my other fully-charged (in winmo) battery, and it lasted for more than a day. Same settings, same use. After it discharged, I recharged overnight from Android and it behaved the same as the first - discharging in about a half-day.
What gives?
I'm curious what builds people are using? I'm totally new to this but I'm using warm donut with voguimg-240x320-06-04-10.nbh. It seems that nbh isn't posted on the sourceforge site yet - maybe I should switch back to an older one?

Maybe kernel problem.
I'm experiencing the same problem as everyone.
Lately my battery suddenly drops from 100% to 4%.
When I put to charge, it reaches 100% very fast. Should reach only 5%
I think it can be a problem in the kernel.
Now, i'm trying to solve it. If I find something I'll share with you
I can not determine which kernel brought the problem...
23/04 - 16:16 (GMT-3 - Rio de Janeiro) - Trying an old kernel
23/04 - 17:00 - Nothing. But came to the conclusion that the problem is with the battery.
Battery really "thinks" its 100% charged, since it accepts flash a nbh without the need of the phone is charging. And this only happens when the battery is at least 50% charged...

My battery life is pretty bad and I recently bought a new OEM battery. Coming of NSFANs 6.5 rom, Myn's warm donut on 240x320 is wonderful but the battery life is pretty lousy.

Another battery moaning thread

I have read a load of threads relating to the battery life, but this is slightly different. I'm on jm1 official and have been for weeks, its was fine until a day ago, now I'm sitting at work, watching the battery percentage go down everytime i look at it, I'm now talking about now when I'm using 3g, just when phones idle.
I went to sleep last night and unplugged phone before I did, fully charged. Woke up and it was on 94%....
Really my question is, is there any way to find out what's using all my battery apart from the built in function which seems to only refresh every hour! I'm not looking for juice defender or such apps

Spare parts can give you, sometimes, some rough approximations. Really, if you started experiencing issues one day, you should try to remember what you downloaded most recently, it might be poorly coded and you should look to replace it with competing software.
Also, there are somethings you wouldn't want to intentionally or unintentionally leave running in the background. Use task manager (not ATK cuz it doesn't track "running" processes very well unless they've updated) to find out if anything is running. Even the marketplace will run in the background and not let your phone properly sleep.

Also, 6 percent seems about right. 2% for all services and 3g off, 6% for 3g? I'll have to look into it when I'm not on my phone. Especially if you dress your batteries by running them down to 0s%, this is bad to do to li-on batteries, I don't know how long it takes to feel the effects but short cycles are better for the batteries health.

Ok, 3g is never on at my house I can't get it there anyway.
The only reason I run it down to 0% is because I'm using my phone and it doesn't last, its stupid to say use it in low cycles because then I'm really only getting 20% battery life anyway...
I have advanced task manager but don't really use it from what ive read I shouldn't have to. And I had thought about the recent apps I've installed and I have installed nothing much new apart from angry birds
Just not happy with the noticeable change in the space of a few days.

If consumers keep "living" with things then they deserve the crap they get. As a consumer, you have the right to be heard so make sure the people you're giving your hard earned cash to is taking your feedback and providing products and services for YOUR needs, not the company's needs.
I'm loosing 10% every night too. It's a joke and I'm hoping the updates will improve it somewhat.

ye i know. but funny thing is, it's rather random. with the same settings and nothing changed at all. sometimes overnight, it drops close to none. and some nights, it drops 10%.
i've lost 10% over 4 hours today with no usage (idle) so lol. i'm glad i'm at least getting 2 days worth of usage.
let's hope this famous froyo does something. sometime soon...

Make sure all applications are dead (ie. use samsung task manager).
Turn off apn (so that you can guarantee no apps are using data).
If you do those two things, I'm sure you won't lose more than 5% overnight.
Personally, if I do that, I don't lose more than 1% overnight.

maybe it's due to over-flashing and all. de-calibrates the battery or whatever. either way, meh.
i've probably only got this calender widget refreshing itself every 12 hours to update the day's events and my Google account on active sync. maybe some applications screwing up somewhere.
to point out, a fresh flash always gave me no problems with battery draining. (after "re-calibrating")

just updated my phone to the TEST firmware JPJG8 which is currently the latest one available thru kies which includes arabic, and have seen no changes from the original firmware the phone came with ( Originally bought from Abu Dhabi with whatever firmware that had the android market not being available )
toying with juice defender for 2-3 days my SGS laged like hell even with the RyanZ lag fix OCLF from the market and it said that i saved 1.5% more juice tho i didnt see any diff with batt, it still drained fast (full charge overnight + extra charge with phone off on my way from home to work and starting @ 100% once leaving my car and ending @ 30-20% in the afternoon about 4-5pm, need to charge a little more if i wanted it to last till 10pm T_T )
deleted it today and thought why not simply use the extended control widgets to disable the connection when the screen was off + switch off the auto sync, like how the program did but manually and amazingly batt life felt like a big nasty battery i felt the diff immediatly.
kept the program juice plotter to see how steep the batt was used to compare the results.
1. keeping my phone on 2g almost all the time except for when i need to browse the net/use msn on phone - i do use facebook/twit and i might be missing the fast notifications but 2g is good with those 2 and battery life sure is extended as i can see.
2. closing the apn when locking the phone and bringing it up when screen is on is a great idea and u can almost instantly tell ur battery life is better
3. keeping screen off as much as possible helped my batt too tho i dont like it but it works.
really noticed a diff in battery usage today so im currently backing up the phone and after a fresh format/restore session will apply root and OCLF and keep you all posted on how long the battery lasts using this method
will test for 2-3 days before reporting again.
Current Battery stat killers are
1.loads of calls
2.display due to a large amount of sms's
see you again after my test in a couple of days

I don't think jg8's a test though unless it's a new rev by kies. used it a month back, pretty awesome but I've switched.
heading to bed now, shall see what happens tonight! such adventure and excitement every night.

jg8 isn't a new rev, it was out for a while and cant be found without using the ctrl+alt+u+p (and if that = test then its not an official release) at the firmware update in kies, its a middle east version with arabic support.
ok impressions on how things went.......
voice calls = 49% with 1H 13M 23Sec
Display = 35% with 5H 0M 9Sec
Cell standby = 7% with 16H 58M 44Sec
Phone idle = 4% with 11H 58M 34Sec
Android System = 3% with 42M 30Sec on CPU Usage and just 20Sec on CPU foreground
batt did last a full day for me i guess ending @ 6% when i got home
but what use is trying to save the batt life when i hardly use the phone
lets say i browsed the net for a 30min-1hour session, watched a few youtube video's/even downloaded video's for that matter or played a game or 2 for like 30 mins to an hour
ofcourse the display will be the major batt sucker by doing this and i doubt it would last an afternoon if i did so in the morning/noon time
I guess my only solution would be an extra batt or 2 for that matter if i really wanna show-off the phone and enjoy it fully for a full day. But the problem would be charging them all without a phone stand with extra batt charger
Anyways, does the batt last a full day for me , yes it does
am i satisfied doing what i did to make the batt last , N O

I got sick of my battery running out at around 3pm at work every day so I've now bought 2 extra batteries and an external charger from spider-foot.com

Well, greetings to all.
I just wanted to share my experience regarding the battery issue.
As I purchased the phone some 12 days ago, my experience is short, but somewhat effective.
First couple of days the battery lasted for app. 24h, with lots of usage (wi-fi surfing, lots of applications installation, calls, games, music, etc.). Then, I installed some "battery-indicator-related app", fully charged battery and used the phone for 15 minutes or so and went to sleep. In the morning my battery was at 80% !(it was on stand-by the whole night), and till 2pm it was at 15%, without using the phone at all.
Battery usage stated 64% "cell standby". I thought - what the .... ?
Than I did the next thing.
Uninstalled that crappy app, installed another one (similar, but other manufacturer),turned off the phone, fully charged it, turned it on, checked that wi-fi and BT are off, turned off 3G and syncs and updates, set brightness to lowest, installed black wallpaper, used task killer to kill all unwanted apps, and decided to see for how long will battery last with that settings and very little usage (couple of calls, sms and some sudoku playing).
The result:
4 days, 18 hours - since unplugged. Battery at 39%.

@ some of your replies
overflashing - ive only flashed once.
be lucky it only drops 6% when totally idle - the whole point in writing this thread was because ive previous lost 0%! when idle for hours and hours...
I have background data off (which i dont want to have to do) i have an APN switch which i use sometimes, but tbh its tedious and i shouldnt have to do this.
as far as im concerned, when i idle the phone, it shouldnt do ANYTHING

[Q] Captivate Battery and Serendipity

Hi folks.
Sorry if this is a redundant question or thread, I have used the search feature and am not getting the results I want. Furthermore I have a 2 year old and 9 month old hanging on my legs here and just need an answer so again apologies if this is redundant.
I have had my Captivate for about 5 days now. I rooted it and installed Serendipity 5.3 ROM. Today I noticed my battery went from 100% to 5% in 4 hours. Is this normal?
I got home and updated Serendipity to 5.4 and then 5.5 but not sure if that will fix the battery issue. The day before I ran the battery all day 10 hours and I was at 35% which to me was normal as my iPhone 4 had the same performance. But 100-5% in 4 hours seems a bit strange.
Any help would be appreciated sorry for the long post I need to get back to my kids.
Thanks!

4 hours for almost 100% battery usage is not normal.
check your wifi setting, gps setting first.

Sounds to me like your battery needs a calibration. It's generally a good idea to re-calibrate your battery after flashing. I generally get 20hrs on my Captivate with Serendipity 5.2 with average usage.

Now that one kid is asleep and the other on her way....what is the optimal wi-fi setting for best battery life and the same for gps?
Also, I looked at that thread and I am in process of trying it out integrasaurus.
This is my first time with an Android phone, I came from an iPhone 4 jailbroken so I am an Android virgin and 5 days old.
I also want to say I am sorry about starting a thread if this topic was hit on already. I have been around forums a long time and I know how frustrating it is when noobs do these things so I thought I'd offer my sincerest apologies for doing what I would get mad at too.

usually after you flash a new rom, the gps is set to on. turn it off if you are not using it;
go to settings->wireless and network->wi-fi settings, then click menu to bring up the advanced->in the wi-fi sleep policy->make sure select "when screen turns off";
go to settings->applications->samsung apps->make sure it is "off"

Hmmm
I dont see this?

I got the wi-fi taken care of though thanks for that.

It was strange today though, I plugged the phone in to wall ac and it took forever (5hours) to charge from 5% to 40% and then drained in less than an hour back to 5%.
Its charging now and has been on my usb port for 2 hours and its up to 72% from 4%.
That was also a confusing mystery.

Hey guys, just want to say thanks again. I'm still working on calibrating batt but I after reading some more in the forums (kids finally both in bed and OUT) I discovered that I had 2 task killers installed and that these apps are battery killers (at least in some opinions).
I uninstalled them and charging seems to be moving faster than before. I will let you know how things go.
Thanks again!

I am running Serendipity 5.5 and my battery typically lasts between 26-30 hours with normal use. I don't use any task killers, but if you have your task killers set to be too aggressive I'm sure that would drain the battery pretty fast. I'd suggest just ditching them completely though, as I get over a day's battery without trying to manage all of that.

Also, check if ur gallery has the sensor bug. U can find this out under battery usage using the SPARE PARTS app.

yup, I deleted them already. I believe that was the cause of the sudden change in life, as I didnt have many problems before them.
After my battery cal I have been running the phone on and off normal use for over an hour. Battery is now at 95%, started at 100%.
I see improvements already, but will hold off saying its fixed completely until I can give it a day or two of testing.

sometimes the thumnails get corrupt which eats battery while trying to load and need to be "refreshed" a simple way to do this is in the app SGS TOOLS run the script "clean_thumb_db.txt" this should fix gallery issues.

Thanks for this info. This will be something I will keep an eye on for sure. Phone is still above 90% after over 2 hours. Hoping the calibration and deletion of task killers did the trick.

Charge battery 100% then some... Power off phone and let charge longer... Boot into Clockwork and reset battery stats.... Run the phone a few charges and you should be gold.... Under normal/light use I can get 1.5 days out of my battery...

Also check your wireless settings. Try setting them to turn off wireless when the screen is off. That was a huge battery drain for me.

Thanks to all here for the help and thoughts.
So last night I
1. Got rid of task killers
2. Updated Serendipity from 5.3 to 5.5
3. Adjusted wireless settings
4. Calibrated battery
I finished all this at 8:15pm CST and the phone has been unplugged since then, with moderate use between 8:15 and 10:15pm. It is now 7am CST and the phone is at 63% power which is a huge improvement from yesterday.
I am convinced it was the task killers that had the most drain on the battery.
I will give it one or two more days and see how performance is then and let you know.
You guys rock!

Back on Serendipity 4.3, while OC/UVing I could get about 25-28 hours with normal use, texting throughout the day, occasional calls.
Now that I'm on 5.5, I am getting about 28-32 hours, still OC/UVing.
Also, I use advanced task manager, and it doesn't kill my battery at all. Any more than other apps at least.

Glad everything is working out for you iDroidd!
..Now back to flashing lol.

[Q] Battery life question - are there different battery versions?

Hello all,
I have a brand new Galaxy Tab ( three full charges so far) - and I get quite different results re. battery life then others.
Then again: I read some posts with really long batt life, and others with shorter.
I have Gingerbread - Overcome RC1 installed, and I in about 1.5 hours use ( no 3G, some wifi, medium backlight; time spent mainly installing / removing apps, some games, some email and web browsing) I am at 75%.
When the unit is fully charged, after I switch it on it goes to 99% immediately (I see 100% maybe for less than a minute). This morning I am at about 65% battery life, with about 2 hours use. ( I have erased the battery stats after installing the Overcome rom).
When not using the unit for several hours (for example over night): I do a complete shut-down.
Now others seem to get significantly longer run times.
Is it possible that there are (at least) two versions of the GT, one with better battery the other one with weaker battery?
Or do I have a defective unit and should I try to return it? ( I am within the 30 days return policy, and could go for an exchange)?
Or is my experience totally normal, and the "really long" battery lifes are more the exception?
Or will my battery life get longer after a few more charge / recharge cycles?
I would appreciate any feedback!
Thank you!

People claiming better battery life are running custom firmwares, have their cpu moderated, and have pulled all kinde of tricks to achieve this.
Also, your battery has to "settle"

Thank you for the reply.
I am also using a custom firmware but no other tricks (slowing CPU etc.)
So my unit is then probably normal?
How long does it take for the battery to reach full capacity?

I think I will return the GT for replacement...
Another update.
Yesterday, I have done a full recycle ( fully empty the battery and fully recharge).
Today, when I started to use it, within 50 minutes the battery level went to 80%.
I have removed now all apps, all widgets etc ( factory fresh gingerbread) and I will fully charge and then reset the battery memory within CW.
Lets see how that goes... but I start to worry now as my return period has just passed ( 14 days from purchase) - so I may be stuck with a unit with a battery problem...

I would reccomend to stop delete battery stat everytime now and then. Another thing is please wait few cycles so battery will settle down as someone said. When I got my SGT for the first time I was quite worried that my battery drain so quick. Simple internet browsing over wifi last for 3-4h. Later on I found tha some apps sync itself constantly, name pulse, weather widgets, rss readers etc. Ive check the apps and disable auto sync. Also moving from 2.2 to 2.3 gives me huge boost and make battery last muuch longer.

Thank you. Lets hope you are right.

Install the version beta2. The battery on it lasts much longer. I checked and returned to the beta2 since RC1. Only first JJ4, then JQ1 and beta2. My English is not good, so I apologize if I wrote something wrong

Wow. That is an interesting theory. I will definitely test: you well may be right. I have used beta2 only for a short time, but I think the battery did last longer...

In beta2 worked for 11 hours. The RC1 is less than 7 hours. A friend has the same. Both went back to beta2. Wi-fi enabled, much inernet ,radio, Google mail, mp3. Used on a single chargefor more than iPad

Same problem here..
Strange it is. .

In the beginning with stock rom i barely got trough one day with heavy use.
Now its no problem getting trough two days of heavy use. Using Overcomes (rc1) latest rom.

I would deffinitelly recommend going back to beta2 as in my case on rc1 I was able to get maximum 7-8 hours when switching to beta2 gave me at least 12 hours. At the moment when not extensively using the tab I am able to get around 60 hours.
ps1
as someone mentioned before pleae stop erasing batterystats.bin
ps2
Do not try to install beta2 on rc1 as it wil cause you a lot of problems. Start with jq1 at least and then beta2.

Hello,
I had the same problem too, but I have resolved it now.
I started by browsing this thread:
http://forum.xda-developers.com/showthread.php?t=986067&highlight=false+status
Then I opened up my tab and disconnected battery for 30 mins. Reconnect and close up and that fixed the problem permanently.
For some people, flashing overcome 2.0 rc1 solved their issues.
Hope that helped.

Battery not so good

I didn't use the note much, but it needs to charge each day. This is bad than tablet. Any software to save battery? I tried 'air plane mode' sofeware, but it also turns off phone after sleep.

What apps and widgets are you running? Have you gone through 2 or 3 full discharge/recharge cycles? There are apps out there that can detect if any app is consuming your battery but you will have to search the forums as I don't know of any first hand.
Also, which ROM are you using? When I was using Rocket Rom v22 with AbyssKernel 4.1, my Note would last more than a day on the same charge even with moderate use. Give that a try as it also really boosts performance.
I'm currently on Team Rocket Rom (ICS based) v5 but have not used it extensively to comment on battery yet. So far with 3 activesync email accounts (all push), some widgets running (weather, clock, etc.) and the Note sitting idle consume about 2-3% battery per hour. Will monitor this.

most smartphones ned to be charged every day, what battery life are you expecting to get ?

battery depends on the usage and applications you installed on the phone.
have you tried rooting already? usually custom roms have the best alternatives of extending your phone's battery and giving it an optimal performance.
Try to stop some bloatwares that your phone's loading up everytime it starts up(from rebooting)

I am using la2 rom. Here i attached an picture.

Geez... i personally feel that one day charge is reasonable especially with the juice required to drive the big display.
Anyway, Juice Defender premium is one app that has helped me, and may help you too.
Since you got Activesync, with the premium version of JD, you can customize app to be excluded from 'power saving', so that the inbox is up to date.

+1 for juicedefender.
Other tips that may not be obvious to first-time smartphone owners are:
1. Set your screen brightness to auto. You don't need the brightness cranked right up all the time.
2. Disable bluetooth and GPS if you're not using them. Juicedefender will do a pretty good job of managing your other radios.
3. If you've got email syncing set up on your phone, set it to check as rarely as you can put up with. Push email uses a LOT of battery life, and even a scheduled check can blaze through your battery if it's happening often enough.
4. If you've put on a custom ROM your phone may be reporting inaccurate battery stats. Give it a full charge, boot into clockwork recovery and wipe your battery stats. You'll find a few days after that your phone will start reporting more accurately.
Good luck, and if any of this was unclear feel free to ask further questions.

I only got one phone call for one min., so i think 1 day is too short.

Try a later ROM to see if the same issue exists. I think you should instal rocket rom v22 - you'll be happy with performance and battery life based on your usage.

try to calibrate your battery as well... there are many apps out there that offers better battery calibration or you can do a manual calibration as well.

Give it some time and upgrade your ROM
I am getting great battery life. It runs for full day (24 hrs) with 30% of battery usage. though in a day i dont use it much, just 5 to 10 calls of around half an hour to 40 minutes.. data and gps always on.. screen brightness on auto...

My note running the OEM battery last me about 6 hrs.
Averages about 45mins talk time/day
About 50 SMS/day
Screen brightness set to 100
Checks email every 5 mins
Using a live wallpaper
Refreshes the daily weather using Accuweather every hr
Bluetooth always turned on
Battery Widget
Fancy Widget
ESPN scoreboard ticker widget refreshes
Twitter running all day
Facebook Widget syncing all day

^ This. Or better yet, just always set your brightness to the lowest brightness setting, 50% afaik. And use black/dark wallpapers and always turn on night mode (if applicable, especially when using your browser)
If in case you need to adjust the brightness, you don't have to go through the jungle of settings, just click notification bar and slide horizontally to change to your preferred brightness.

Jd is hit n miss will actually helping out. If your phone sleeps a lot jd is nice at keeping cell or wifi off if your like me and on it every 10 minutes then toggling data and other things can consume more juice. .... I have tried with and without on my tablets and phones and see no big difference depending on use.
Sent from my Ice Creamy Galaxy NOTE

I was pretty happy with my battery until two days ago. I use my note very little, for e-mail checking (which I pull manually) a few times a day, and to make two or three phone calls per day. I also text my kids occasionally. GPS and Bluetooth are off most of the time. Battery used to last me about two and a half days under these conditions, which seemed reasonable to me. All of a sudden, two days ago, I charged my battery, and after a full charge it drained 60% overnight. Thought that it was a fluke, so rebooted my phone, fully charged again, and the same thing (over half of the juice gone overnight) happened again. Battery stats tell me that Android OS were 100% responsible for overnight drainage. Any clues? I am on stock ROM, by the way.
Thank you.

Get a good app to check what is using the battery or keeping the phone awake. This last is the most likely.
Baddass Battery Monitor is my recommendation.

Not a single phone call, only used about 10 mins. after 21 hours only 11% left. Install Jd with 'balanced' option.

Thank you. I will give that a try.
Badass, got to love that name....

Ok, I used the Badass monitor to see what's going on. Once again, no phone usage, quick overnight battery drainage. Android OS 100% responsible, and the main power sucker is the Kernel (96%). Why is this happening? And, is there a remedy? I have changed nothing that would trigger this! My Note is still within the return window, so if there is anything wrong with it, I will return it.
Thanks again.

Badass Monitor is very useful, my note was drained by Dolphin Browser, it used 38% of battery. Seems like for this browser, if I only press home key to exit, It will keep running?
I think the reason the battery drain fast is we press 'home' key to return to main menu, that will keep a lot of apps run in the background.
