Is it okay to leave the Captivate plugged in over night?

So I think I have read that it is not good for the battery to leave it plugged in on a full charge. Last night I went to bed at 3 am on a 30% charged battery. I THOUGHT it was at 50% when I went to bed but looking at juice plotter I was wrong. At 8 am, according to juice plotter, the phone died. I missed my alarm and was late to work (my new job I have had for 2 weeks btw...doh!).
The screen was off and I have setCPU to underclock the CPU to 400 max 200 min when the screen is off. With the screen on and battery set to <80% the phone is underclocked to 800 max and 400 min. Basically the only time I have the CPU set to 1000 mhz is when it is plugged in.
Anywho, my question is this: Can I keep my phone plugged in while I am sleeping to insure this doesnt happen again without killing the longevity and usefulness of the battery? I know this time was mostly my fault with the battery being at only 30% when I went to bed, but I am trying to find a good balance between optimizing the battery and making sure this doesnt happen again.

Its how i charge mine every night for a month now. And no issues.

Have you paid for Juice Defender? If not i'd recommend it. I've spent the massive $4 for this app and like the rest of the customization for the power configuration. I used to leave my captivate on the charger all night but I don't anymore.. Not sure why your phone died on you, how do you have Juice Defender configured?

With a low battery level, you should charge your phone for anywhere from 8-12 hours. Battery indications are generally always incorrect. When your phone says it is at 100% after a few hours, that is incorrect. That is generally how it is for all electronics.

SetCPU has known issues with all SGS phones, Captivate included.
I had my phone depleted to 10 to 15% quite a few times now and I had no problem with charging. And I always leave my phone plugged in whenever I'm home.

You should be fine leaving the phone plugged in. The smart part of the charger is in the phone. You will get repeated charge complete notifications i think.

I have the free one. I must not know what exactly it does. I thought it just plots what the battery is doing?

Should I take setcpu off my phone? I know there are kernel issues I believe.

What's the benifit of the setCPU other than crash your phone ?
The biggest battery hog is always the screen display. If you're running stock JF6 ROM, it is well over 60% of the battery usage. Newer firmware does a better job controlling the screen brightness but still amount to 50% of the battery usage. The second biggest battery hog is 3G data transfer (or wifi data transfer if you primarily use wifi).
The saving from underclock the CPU will not be that much, IMO, other than make your phone feel slow I guess.

I permanently underclock to 800 mhz when using battery power. It still seems quite snappy to me.
If it is known to crash the SGS a lot, I will take it off. Guess I need to do some more research.
Any tips on how to handle the display?

Either flash to the newer beta firmware JH2/JH3 or manually dim the screen down. The automatic setting doesn't work well in JF6 firmware.

SetCPU is used to overclock, underclock, set different CPU throttling profiles. I don't think running setcpu is going to effect how fast your system is by running in the background, it uses like zero cpu cycles. My set up is currently the hybrid rom, setcpu oc to 100 to1.2 interactive and with the screen off 100 to 600 conservative. Ultimate juice defender set to turn wifi and 3g on only when certain apps are running that I picked, along with being one 1 min every 15. I'm getting about 36 hours a charge with average use, and I use about 1% an hour to every 2 hours in standby. My little juice defender score thing hovers around 2.33.
Setcpu does have good advantages, just learn how to set it.

I didn't mean setCPU itself use much CPU cycles, but rather by manually underclock the CPU to slow it down.
I see in your setup, you turn off the 3G data hence get better battery life. Unfortunately, it doesn't work for me. As I have 3 push email accounts: one Gmail, two Exchange Accounts which requires constant 3G connection.
If you leave the Juice Defender off, how much extra battery life do you get by under clock your CPU? One post I read that states once he removed SetCPU, his battery life actually improves.

Do you guys use JuiceDefender as an alternative to a Task Killer or side along with it? and does it work well with the captivate?
I keep myself plugged all night ALL the time and I'm also constantly on the phone from at least 12AM to 4AM while plugged in during that time. Haven't had problems so far.

Im patiently waiting for an official update. If it doesnt come by the end of my 30 days (which is 28 days away) at ATT, back the phone will go.

maybe something wrong with radio rom? (or how it is called)

If your phone stays in weak signal area a lot, that could kill your battery quick as well.

Yeah that happens to me, happened on my iPhones as well. My signal constantly switches between no signal, gprs, edge and 3G, it is never consistent and the searching just kills battery life. AT&T have been getting deluged with reports via the AT&T Mark the Spot app so hopefully they address the gap in coverage here soon!

Semi on-topic question. Is there a way to test battery health? I used to be able to get 36 hours on a single charge, and my phone was loaded with a ton of widgets and crap. Now I am lucky to get 12 hours and I have zero widgets, wifi always on, and a black lockscreen/background. Also running stock free juice defender.

Also, does anyone have an issue where they unplug their phone, and its already at 99% even after a full night of charging?

[Q] Please help with my battery life!!!

Hi guys, I love my SGS, but the battery life is killing me!!
I've tried 3 different ROMS, but all pretty much the same. I'm now on the 'official' JP6 / JPM. Phone is rooted, and One Click Lagfix running.
Display is set to minimum.
I sync an Exchange account using push. I've turned off gmail and facebook sync.
Using LauncherPro.
Basically, I unplug the phone from the charger at around 7am, and by 5pm it is dead!!
!!
Any suggestions!?

1: change your push-settings for exchange to 30 mins or an hour ( i did too , its better )
2: buy a extra battery
3: bring your charger to work
4: stop playing non-stop with your phone
to sum it up. we cant tell you what u are doing wrong with the small info u gave. you dont give % of battery usage ( liek 60 % display, 20 % standby etc )
all in all, i can say atm. stop push-mail
( i have same prob , i just leave my USB charger @ work lol)

root it again.

Also set phone to 2g mode rather then 3g and install juicedefender with nobars too.

There is no proof that 2g eats less battery

2g relly eats less that 3g. But i'm use both + wifi at home + look a flash video, get rss every hour and phone lives 36-48 hours on one standard battery. Maby your battery is dead. Replase it

Do it this way:
Make the phone empty.
Charge it all night (8 hours + ).
While still charging, open applictaion: Terminal Emulator (it is available on the market for free)
Write:
su
rm /data/system/batterystats.bin
it looks like that nothing really happens, but it does.
Reboote the phone. Important!
You will see the difference. I get from 1 day before to 3 days now.
For doing this, your phone, of course, should be rooted.

eh?
what would you like as a proof?
sure if you live under the antenna consumption may be the same, but 2g is much less processor intensive and has longer range.
so your phone works half as hard in 2g than 3g (both idle and on line)
with just 2g and only using phone features i can go 5-6 days
same usage with 3g goes down to 3 days
and that is with having mobile data off in both cases

2G eats muuuch much less battery. I didn't have 3G for a few weeks, huge difference in battery life.
I use Juicedefender just so that nothing goes on with my phone while the screen is off, only update rss/weather/sync when sync is on.

Can anyone confirm if this method works?
(On a side note: I'm looking for someone who can help me flash Korean firmware onto European phone so I can get "record call" feature. Thanks)

I manage to get 3+ days of battery time... I have data connection inactive, no syncs, and using a black theme Battery life just improves over time, after like 5 or 6 cycles of charging.

I've had my phone for a little less than 2-3 weeks. While my battery has gotten better with a few full discharge/charges, I still haven't reached those insane battery life times that some have had the luck of having.
I've done the full discharge method a few times. I've also done the "charge (on), unplug, charge (off), turn on for a few minutes, turn off, charge (off), method twice.
I have juice defender to set to keep everything off and only connect for 1 m every 15 m. I have root, but I've removed lagfix.
Yesterday night, I slept for around 6-7 hours. My battery life dropped a full 40%!
Here are my battery usage stats:
Display 44%
Cell Standby 20%
Android OS 14%
Phone Idle 13%
Android System 5%
I'm wondering if my phone or battery is defective and I should ask for a replacement?

Hey, try the 5min evey 2hours, that's what i have and i don't have any issues.
Obviously something is wrong. THis happened to me before, it was because of FB and google sync as well as the widgets constantly synchronizing and using mad data.

Welcome to the SGS.
Typical usuage for my SGS:
0800 - alarm used to wake me up.
0805 - disconnect from charger - full battery
Sync: K9 Mail - once an hour, headers only or messages less than 2Kb.
JuiceDefender: Data connects 5mins every 30 mins, otherwise 3g radio or wifi is deactivated.
Average time on 'phone calls: 10 mins.
Wireless use in work: 20mins max
3G/2G usage: 20 mins.
Brightness set to lowest setting.
Doing the above will empty a fully charged battery by about 1800, or usually sooner.
9 hours of use until empty, when the 'phone is predominately on stand-by.
The wireless and 2g/3g data radios are a real killer. With the data connection of, then I can watch the whole of the Avatar film on the device, and even have some power left over from some 'phone calls.
Solution: Don't use the SGS for data while not running from the mains power. It'll save the battery.
So, don't use the SGS for business. Its an expensive toy that pretends to be mobile, because really one it tethered to an electricity socket. Welcome to Android 'phones. Other than the lag that causes the 'phone to be unresponsive for a couple of mins, I like the device.

check your apps, I used to use widget locker and it'd drain about 30% a night. I dropped it even though I used to love it, I think they pushed out a bad update 2-3 months ago and never made it better.

Hrmmm, I don't have any out of the ordinary apps running. I've made an effort to check all apps and ensure they don't auto sync/auto - update or do so very rarely.
Apps I have:
Juice Defender
AutoKiller Memory Optimizer
Facebook
Whatsapp
Yelp
Uninstalled Tango
Uninstalled Samsung Apps
SMS Time Fix
The rest of my apps are either stock or don't use internet

At some point I shall do a factory reset and start again.

* In most phones when switching from 3g towards 2g will result in +1/3rd increment of batter-life
* Extra launchers(UI) will play a lot with your battery, best is to have only one running, not TW along with launcherpro
* Turn OFF the gps cos i noticed, by keeping it on, that it's a huge drain on the batterylife.
* check apps and be sure none will run in the background with adds (remove them with an add remover)
* flash to jpk and root with oclf, many complain about their roms, but after 130 apps and a month mine is still working splendidly, with maybe and just maybe the lagg once a week. (could be titaniumbackup at that moment)
downloaded a thing and send a few messages and it's at 85% atm, that's after +6 hours of use. (it was at 98% after 4 hours with a few uses)

Ok guys, Dark Steel JP6/JPM, hardly any apps, 1 Exchnge account.
I took the phone off charge at around 10am this morning, now at 6.30pm, down to only 16% left!!
Stats:
Display - 77%
Cell Standby - 17%
Phone Idle - 6%
I don't get this, the battery life is awful!! I've hardly used the phone today. Display brightness is set to absolutely minimum. 30 second timeout, and hardly used, so the screen has hardly been on!
Apps I have:
Flash 10.1
SetCPU
Remote Desktop
LauncherPro
Smart Keyboard Pro
ROM Manager
SGS Tools
Spare Parts
Plus the normal Maps, Navigation, Flash.
GPS Off. 1 Exchange account set to Push. Gmail sync turned off. Bluetooth used for around 30 minutes.
Please help me!!!! I've tried 3 different batteries by the way, so it's not that!
How many charge cycles does it need to sort itself out after deleting battery stats (deleted via clockworkmod recovery)?
Thanks!!!!

Your phone idle is only 6%, something is stopping the phone from sleeping. Give us the reported times for display, idle, e.t.c

What would you do when ...

hi all ,
my phone is having some battery drain issues ...when i use GXP v22 the battery drain 1% everty minute in standby ..no battery in just 2 hours with GDX it last only 10hours
even when i full wiped , clear dalvik , wipe battery stats the battery still dies to quickly ...
so what would you do?
oh ya i got this rather odd problem the battery went standby for about 4hours ..the battery was 75% and still is ..but then when you use like 1 minute it drop another 1% ..why?
will the launcher be he culprit? i use launcher 360 ..
i off everthing , 3g ,0% brightness , no haptic , no wifi , no bluetooth use silent etc...

flash the other rom after flashing gdx without full wipe.. hope it works ...

Try another "Rom" i guess it's not the launcher but the rom itself, try XGin 6.2 it has a great batt. life. been using it for over 2 weeks now and i'm pretty happy with the battery life.
wifi always on, calling, texting, media streaming, brightness set @ 70%, surfing and my batt last for about 1day 7hrs..

will it help if i give it some time ? maybe a week or 2 ?

I don´t think so.
But that battery drain IS NOT NORMAL, I normally get beetween 24h and 48h of without charging, sometimes even more, and less when I use Wi-Fi or play 3D games.
There´s a battery calibration app on the market:
You charge you phone, an when it´s at 100% you click a button and then the app wipes your battery stats.
You can also set an alarm that rings when the battery is on 100%.

GingerDX v022 on Stock Kernel, smartass governor (default scaling values of 122->600 MHz)
With WiFi and 3G turned OFF the battery drain is 1% in ~2.5-3 hours (phone idle).
With 3G turned on and WiFi turned off the battery drain (almost full reception) is 1% every 4.5 minutes!!! (~7 hours before the battery dies)
With WiFi turned on and 3G turned off the battery drain is 1% every 15-20 minutes (phone just sitting there causing the usual traffic of Gmail, Talk, Sync).
Try to set your phone to a comparable configuration (no idea if GXP has a CPU Governor setting - in GDX it's in CyanogenMod Settings) and try to replicate the test ...
From the "with GDX it last only 10hours" you wrote it sounds like your phone is constantly connected to WiFi or 3G (and maybe having download/upload traffic going on - therefore increasing the power consumption).
EDIT:
Also note that overclocking (as I recall I spotted a overclock thread of yours) will chew the juice out of your battery at a way faster pace.
Keep in mind that the values may differ depending on the GSM/3G reception ... the weaker the signal, the more power the phone needs to apply to communicate with the tower. If you're in an area where the reception is poor you shouldn't wonder about the battery getting eaten.
As a last resort, keep an eye on what applications you have running in the background. The more crap you got running, the more bat drain you're going to have when processes are fighting over CPU time.

NONO i never on wifi / 3G / bluetooth / GPS ..cause of the poor battery i tried my best to save as much battery as possible ...but in no use =( i cosntantly use task killers and i use smartass governer i think i will try stormvix ..oh! and starting my phone eats about 20% each time i does it ..is this normal?

i tried the battery calibration app ..doesn't do jack =(

should i pcc my phone? and redo everything

"starting my phone" translates into what ... ?
Turning it on (from being powered off) and letting it boot up results in 20% loss of battery charge?
That's NOT normal at all ... your charge should lose 1% at best if it was already close to going down by a percent.
Using the phone for a phone call makes it lose 20% battery charge?
Well, that entirely depends on the length of the call and the reception. Going down 20% would be about... hmmm... 1.5h talking time (estimated from the top of my head)?
At any rate ... a rapid loss of charge like your 10 hours while the phone just idles around twiddling thumbs and not being connected to WiFi or 2/3G is not normal no matter how you look at it. EDIT: Unless you overclock sky-high and running the performance governor which would keep the CPU fully clocked no matter what's currently going on.

starting in the sense like restarting eg entering cwm / xrec ...i flashed back to stock now ...gonna do it all again .. i knew this was too much drain i off everything even background data and i use smaratss 122 - 710 , even my brightness is 9% ...

Just for testing purposes to see if the bat drain stays within a sane stretch I recommend you stay with 122-600MHz.
It would also help to install some app/widget that monitors the current clock of the CPU - just to see if there's something which keeps your CPU busy and therefore running at full throttle. I recently saw something like that, I just fail to remember where and what the name of the app was ...........

okay so i flashed to stock last night ..i on everything sync , wifi , bluetooth , data etc for 5 hours it drained only 10% surpisingly ...after 10seconds it restarted and dropped to 3% ..odd...and i fully charged my phone to 100% and left it there for about 1hour and it dropped from 100% - 86% ..any solution?

There are only two things left that I would consider ...
a) The circuitry monitoring the battery charge is bogus and pulling random values out of thin air (would indicate a hardware defect in the loading circuit on the motherboard).
b) Any change the guys who repaired your phone from the hard brick returned your device with a old, almost dead, battery instead of the shiny new one you had in your W8 that bricked (you know, shady retailers thinking to make a few extra bucks by selling off the battery of your dead phone as used-part replacement to earn a "little something extra")? This would closer match to the 10->3% / 100->86% jump symptoms - the battery being about dead and therefore unable to hold the charge and draining like wild.
I don't know which of these two options to favor, but I would give "b" a 51% chance over "a".
EDIT: Stay with the Stock ROM and complain with either the repair shop or SE as the drain problem can be reproduced any given time. This should actually be covered through warranty as the original phone wasn't that old, and the repair is somewhat unrelated. The battery should at least last for two years before you should observe major degrades.

Optimux2X battery life with ICS

In threads in the Optimus2X development forum I often see posts that praise the battery life using new ROMs or basebands or RILs. The numbers always surprise me and make me jealous. I have read about some guy whose phone loses about 3% battery during the night, or some other guy who still had 75% battery left after 7h of 'normal' usage.
Today, I unplugged my phone from the charger at ten in the morning and 3 hours later, I had 80% battery left, with the phone only resting in my pocket in standby. Now, about 8 hours unplugged from the charger and less than normal use (15 min browsing, one GPS localization, two SMS sent) I am 25% battery.
I have disabled WiFi, decreased display brightness to the lowest value, always disable GPS & bluetooth unless I need it (which is very rare).
I am currently on owain's CM9 build 62, baseband 313 and RIL 218. I have also tried BB 725/RIL 725 (which caused big problems) and BB 420 / RIL 1120. Both did not give me a noticeable longer battery life.
Whats up with my phone or battery? How can I extend my battery life to the numbers said in the beginning?

battery
buy a bigger battery
i have a 3500mAH battery
more then 2 day on 1 charge
look on dealextreme

12 hours 30 mins, with 25% battery left
Over locked to 1.4ghz
Screen on 2 hrs
Calling 2 hrs
So yeah , I guess its pretty heavy use...
It also goes alright (;

i would say something is definitely wrong with your phone, rom or kernel. i use my phone even to play, games like dead space and more, and my battery always lasts for 1 day at least, also oc'd to 1.4 ghz.

I had the same prob, But I solved it,
now my phone survives a full day with normal usage.
Receiving/sending mails tweets facebook post G+ browsing the web etc.
try to drain your battery until your phone shuts down by itself
then fully recharge it after that unplug it and start it up again,
I hope it helps it did so for me.

X9 Battery Life

Just wanted to share that the battery life is very good on the X9. I am getting about 5.5 hours of screen-on-time.
I unplug the phone at 6am and at 11pm there is still 15% left with at least 5 hours of SOT.

That's excellent, I'm only getting around 3 hrs SOT myself.

Yes, I confirmed it. My X9 is in good battery life, normally I only need charging it once per day, even if I used it to browse web, some gaming.

Same here. SOT is consistently 5hrs+. This includes some gaming , alot of web browsing and some music.
Screen at 40% , 4g off , battery saving location setting and haptic feedback/ touch sounds disabled.
Everything else default.
Even if fast charging is only ver. 1.0 battery life is good enough to not need faster.
Very happy with this phone all around.

Slightly disappointed with the battery life. The standby power usage is not great compared to my other modern android phones. It is lightly debloated with all the power saving feature on except power save mode. Using power save mode only brings it to about the same level of my other phones without it on... Then, there is my Z3c.
~5hour screen on time is not great as well. Comparing similar screen size phones, it is pretty bad as I get about 6 on my Note4 (which is faster and pushing a higher resolution), and Zuk Z1 (CM13 with undervolt), which easily get 9-10+.
Edit: Some overnight numbers.
My main phone is an S6 and before going to bed was @ 43%. Checked phone 11 hours later = 38%. This is with wifi on and syncing 3 google accounts, 1 IM, NO SOCIAL MEDIA.
X9 @ 52%, with Wifi, sync off (no IMs/SM installed), no BT, no location, 2 SIM active (both get 5 full bars @ connection) = 41% checked at the same time. Doze is on and confirmed working. I've used with only 1 SIM before and it really doesn't change the numbers that much. I wouldn't be so harsh on the phone if it had quickcharge 2.0. But it only charges slowly @ ~5V 0.96A. There is something funky with the charging numbers, since it bumps up to ~1.1 amp after ~80%. It also doesn't trickle charge after 90% and only drop to trickle charge after hitting 100%. I am not sure about the battery longevity on this thing.

I had bought my x9 2days back battery drains very quickly.....disappointed any solution plz

Same with all phones... check all which apps are the most hungry.
If you suspect its an hardware issue, factory reset then uninstall/disable as many apps as you can, charge up and let it run and see if it last normally.
Usually it should be some apps eating up the battery.

There is an app (3C Battery Monitor Widget) in which you can inspect your battery to see if it works in normal condition or not. It shows you amount of real amperage drained from cellphone battery in different situation.
As I tested mine (htc one x9) it drains maximum current when capturing photo or recording video, location(gps) is on and map apps like google map is live, switching between different applications which result to rise frequency of cpu up to maximum (1.95 or 2.2 ghz in different model).
If you enable power saver mode in setting, maximum frequency of cpu wil be limited to about 1.32 ghz and conserves more battery and limits drained battery current below 900mA otherwise in aforementioned cases drained current will be raised above 1000mA and it is obvious that (3000mA/hrs) battery will be empty during 3hrs. Anyway normal application such as web surfing (specially with WiFi instead of mobile network), listen to music, talk with phone and brightness of display below 50% will result to more than 5hrs SON.
If you need more battery SON, one way is limit CPU/GPU frequency and some more sophisticated setting (you should first unlock boot loader, then root and also install kernel application or change stock kernel with custom kernel which can support change of CPU parameters the former is easier and the latter I couldn't find until now anything)
Finally I would be happy to announce you that I could reached 8 hrs son with this technique on my HTC ONE X9.

Battery life is quite good on my device too. Although I have disabled touchboost.
To disable touchboost open build.prop and change
ro.mtk_perfservice_support
From 1 to 0. Root is needed though.
Also limited max. Freq to 1.7GHz
1.9GHz is just an unnecessary heat generator and battery drainer.
