Samsung Fascinate :: Battery Draining In 3 To 4 Hours After Rooting
Nov 17, 2010
I just rooted a few days ago. Put a custom ROM on it (KaosFroyo v38). Ever since I rooted my battery dyes in about 3 to 4 hours. My phone says its awake 99.9% and the android OS is using 40-50% battery. Is it possibly the ROM? If so how can I change to a new one? I have a Droid Eris.

I noticed this today, I use my phone to USB tether, and after coming home from running errands today my phone was at about 80% battery life, so I put it on the USB cord that it came with and connected it to my computer so I could check email and facebook, etc. Well after a few hours I took my phone off the charger and the battery had dropped to 40%. How is this possible, I know tethering uses power from the phone, but if its connected to the computer and charging as well, why is it still draining my battery? my droid never had this problem and i tethered all the time, is it possible that I have a bad battery?

Following my last thread for same reason,"full charge battery goes empty in less then 3-4 hours,even with wi-fi,gps, turned off",with tip of you guys,i monitored battery usage with "spare parts" app,first i haven't notice anything unusual: SPARE PARTS gave me very normal cpu usage:1-android system2-browser, but then in the end of list of usage option,i checked other usage & what i found was very interesting:
SPARE PARTS>battery history>other usage>total in all time:
running =time without sleeping 28.1 %
SPARE PARTS>battery history>other usage>since last unplugged:
running =time spend without sleeping 99.999 %
SPARE PARTS>battery history>other usage>total since boot:
running=time spend without sleeping 99.999 %
Now i guess i know why my phone run out of charge in less then 3-4 hours,question is what i have to do about it?
any solution please? previous post:with a full charge battery in STAND-BY, it takes just about 3-4 hours for battery to be empty! help!
also i checked main setting now: setting>about phone>status>Awake time 100%

My girlfriend and I both bought this phone from Verizon last Friday. We both let the battery run down completely before charging it up (which I was told by the Verizon rep was the "way to go"), and we have both been experiencing GOD AWFUL battery life. Strange battery behavior has included (but has not been limited to):
- Battery going from 100% to 5% after 5.5 hours straight of browsing, playing games, etc., followed by the Battery going from 100% to 5% after 5.5 hours of idle (with light texting and a few quick phone calls mixed in). Seemingly no consistency.
- Battery draining down to around 30% after about 8 hours off-charger with light to moderate use (a few web pages, a few apps downloaded, and about half a dozen texts). If this wasn't annoying enough, shortly after reaching 30%, the phone suddenly took a nosedive into the red, and warned me that I had 5% battery remaining.................

Has anyone experienced this? I searched the forums and the common answer was that 3 hours was normal but it takes my phone around 8 hours to charge on both USB and wall charging.
I just got the fascinate a few days ago. Defective battery or handset? I called Verizon and they said that it can't be troubleshot.
I really like the phone but 8 hours is excessive.

Battery life issues for me are over. In the beggining I would be happy if the battery lasted for 2 days. Now I can have my phone always on for 7 days straight, that is 168 hrs (when using very limited wireless data connectivity of course), thanks to Galaxhero and some other tweaks.But anyway, lately I've been doing some tests regarding Google Latitude. I suspected that Latitude was messing (not just) a little bit with the battery life.So, yesterday at 9AM I unplugged the fully charged phone that had the Latitude feature on. Result: at 5PM the battery was at 90%.Today, I decided to turn off Latitude (leaving the rest of the configurations intact) and unplugged the fully charged phone again at 9AM. Result: it's 5PM and the battery status is at 100%.

The last day or so after charging my phone to 100% overnight (phone is on when charging) and then putting in standby mode I'm losing like 5-7% of battery every hour.Over the weekend I was losing just 6% every 9 hours in standby mode. Today in 4 hours time I'm down to 65% already with mostly standby mode and a few minutes of browsing. I even had JuiceDefender installed since last night and it's not helping at all.To me it seems that something is in the background that is draining the battery though I when I check running services I don't see anything that shouldn't be there. When I was losing only 6% every 10 hours I did have a live wallpaper, weather/clock widget, and task killer. I didn't change anything on the next charge and now I'm constantly losing battery even in standby mode.
I have Wifi/GPS/background data off, brightness at minimum, no animations, etc. So pretty much followed all the battery saving pointers. I thought it was working good when I got just about 36 hours over the weekend with standby and moderate usage. So I don't know what has happened to my battery all of a sudden.The two times that I have managed to do 30+ hours on a single charge I had Advanced Task Killer running.However, even after doing 36 hours on one charge the next day even with ATK the battery started to drain a lot every hour in just standby. Anyone else having similar issues? I don't know what else to do at this time. I've uninstalled many of the apps thinking it might one of them causing the issue, but still having issues.

Battery is draining fast on SGS. comes down from full charge at 4 am to 70% by 8 am without any usage. During the day will have to charge it twice. Any possible causes or tips to manage it? am on EDGE with air-tel but use wi-fi mostly.

I'd like to thank the people over at XDA.I think they may have found the culprit for the horrible battery performance some of us are seeing. There are two threads of interest over there:Time without signal > 50% - xda-developers Wow battery from 100 to 10 in 3 hours xda-developers.The short of it is that the 3G signals don't stay locked and the phone keeps hunting.If you go under the battery life settings and click on "Cell Standby" there's a field for "Time Without Service".Mine and many others were hover around 50%.This is constantly draining battery even while you do nothing.So the temporary quick fix is to turn on Airplane mode, then turn it right back off.This fixes some incorrect setting.On my phone, Time Without Service dropped from 52% last night to 0% today.And my battery only dropped about 9-10% idling over night.This is MUCH better than the 30% draining overnight I was seeing over the past few days.

I went to bed at 1am and woke up at 10:20am. My battery was at 65% before bed and 44% when I woke up.
I killed all tasks with advanced task killer as I do throughout the day as well. I don't use the email program on my phone nor do I get any notifications for any other programs. My Wi-Fi sleep policy is set to never because I have Wi-Fi at home. Brightness is at a low setting too. So, any ideas what would be draining my battery during the overnight when I'm not using my phone? I don't have problems during the day when I use it.

Since I got my Captivate just a couple of weeks after it hit the market, I experienced really good battery life. I could plug the charger in at 6:00 when I get up, take it off the charger at 7:30 when I leave for work, and make it til the next morning most days.A couple of weeks ago, I left for work with a full charge, and around 11:00 I took out my phone to test WiFi coverage for some new access points we had installed in the office. The phone felt very warm, and the battery indicator was yellow. For the next couple of days it went like this. I had a spare Samsung battery from when AT&T sent us a new one for my wife's Captivate when she was having random shutdown issues, so I swapped batteries. Things were fine for 10-11 days. Then suddenly last evening about 7:30, when I went to look something up online with my phone, it was very warm again, and the battery indicator was red. Had to put it on the car charger when I left church.When I got home, I put it on the charger all night. By midday today, it was in the yellow, and it finally died about an hour ago. again the handset felt very warm. I don't have a spare USB cable here at work, so will have to wait to get home to charge it. Anything particular I should look for on the phone (running apps, etc.)? Or do I just need to go ahead and place a call to AT&T support?

I got my Captivate about a week ago and some far I am liking it a lot. However, I thought I was having some battery issues, as my phone is draining faster than my brother's iPhone.
Using one of the battery status widgets, I've noticed that my batter drops about 1 percent for every text that send and receive (send one text+receive one text = 1% drain) meaning that I'd only be able to send about 100 texts in a day on a full charge. Most days I don't reach that but there are some days which are pretty text heavy. Is this a normal rate at which the battery should be draining for doing something like that? I am using Juicedefender and Advanced Task Killer to monitor what is going on, and the only widget I have running is Fancy Widget.

I've been getting pretty good battery life (about 14-16 hours on average) when I use the airplane mode trick and kill the Media Hub service. However, my phone has not been able to sleep since the past 2 days and the battery is draining quickly.
The up time indicates that the phone cannot go to sleep. I'm just surprised because I haven't changed any of my phone settings so I don't know why this is happening. I uninstalled the last app that I downloaded and that didn't help.
Should I try doing a hard reset? Are there any apps that will specifically tell me what is keeping the phone awake?

Minimal use, but still. Probably about 20 texts and checked email 3 or 4 times. Currently unplugged for 12+ hours and my battery is at 90%!
Let me first say, I'm rooted and running a noobnl's Andromeda custom ROM, bloatware is removed, OmaDRMconfigService.drm removed.
3G and wifi off by using Quick Settings (from market) except when in use.

I've a Galaxy and I installed the rom GalaxHero, but last few days my Galaxy uses a lot of battery. Turn On the phone at 13 o'clock, still in standby, at 21 o'clock the battery was at 55%. That is completely abnormal. I've installed the application "spare parts" and I see that in "Battery History" - "Other usage" it reported running 97%. So I Installed another program, "Drain-O-Meter", this brings me to the process "System_Server" which uses the CPU to 100%. The battery lasts me very little, maximum 24 hours in complete standby. Before we even did about 70 hours!

I got CL14 on the 19th after having my moment for a couple months they fixed the battery gauge! However, I got a new issue with CL14. I work at a job that is in a bomb proof area. I have always left my phone on in the area even though I usually get no service, sometimes one bar.
The reason I leave the phone on is because sometimes I am in there for 2 minutes, sometimes for 3 hours between breaks so with the long boot times it sucks turning on and off and and off (especially if I am only in there a minute). I also cant switch it off while I am in there since I would get in trouble for taking it out of my pocket.
Eveything had been fine until CL14, now when I go into that room with little service after about 1-2 hours the phone battery it totally dead. The phone is very hot to the touch as well. at first i though it was the screen was somehow on, but I have been checking it every few minutes and its not. Basically my hunch is something changed in the CPU usage when the phone is searching for service with the CL14 update that causes the battery to run out of juice (for real this time) very very fast. Any setting I can change? Most regular cells go into a "power save" mode when there is no service, the moment does not.
Cliff notes:
Cl05, battery gauge, but no problem for months at my work with no service.
CL14 installed now battery is being completely drained from full to shut down in 1-2 hours, in low/no service areas, phone getting very hot.

I understand the wanting to remove Bing as the default search engine and getting rid of the bloatware, but those are just annoyances to me. Not something I'm willing to brick my SF over.So, I'm asking, what exactly are you doing to the phone when you root it and are there any other advantages to rooting other than getting rid of annoyances?

I finally got my fascinate yesterday. I know that there is a app out there called wireless tether that is used for a mobile hotspot. I know it requires rooting the phone. I need a simple very detailed instructions on how to do this.

Anyone try the wireless tether app after rooting? I must admit, I love my Skyraider ROM'd DInc, but damn that phone is sexy! 2.2 is nice, but if I'm tethered, I could wait.

I was gonna by a Fascinate when i get my new every 2 but the /forced Bing is a huge turn off. I'd like my Google Android phone to be exactly that, a Google Android phone.

After noticing my battery was draining quickly, and then after reading this thread, I installed Android System Info to see what was draining my battery so fast. I notice that whenever I would turn on WiFi, the phone will never go to sleep , regardless of what I set the WiFi sleep policy to. After turning off WiFi, the battery still drains heavily.
The WiFi will shut off after 15mins (if you set it to "When screen turns off" or "never when plugged in"). However it seems to keep the CPU on causing it to drain down the battery.
It would seem that whenever WiFi is enabled, the Android system process creates a partial wakelock that does not go away even if you turn off WiFi. The only way to resolve this is by powering off or rebooting the phone.
You can verify this in Android System Info by going into Battery-History-Other Usage-Partial Wake usage to see how much time the "Android System" process holding a partial wake.
I even did a factory reset on the device; and it is still happening so it doesn't appear to be any app that caused the issue. As I said, it works fine as long as I don't enable WiFi.
I already know of two users having this issue, but I'm wondering if folks having battery problems are going through this as well. Is anyone else having similar issues after using WiFi? I'm hoping someone will be able to identify what exactly is putting the wakelock on and we'll be able to find a fix for it. Other than not using WiFi at all or rebooting the phone after using Wifi.

I know Universal Androot says it supports the Galaxy S, but does that mean the Fascinate is also supported? Trying to help someone out here and want to give the easiest and safest possible rooting guidance.

Do those numbers seem normal to the rest of you? Right now if I am using my phone for browsing, video, etc. it will run the battery from full charge to dead in just under 4 hours. If I just leave the phone turned on but with no apps running (standby) it runs out of power in roughly 48 hours. Is this the battery life I should expect from this phone?

I followed this tutorial exactly: How to Root - Android Forums
1) i downloaded/installed the drivers
2) i unpackaged the rootkit onto the sdcard
3) i executed start_root.bat
4) the script(s) ran and the phone rebooted.
now, when i connect the phone to the computer (any computer) via usb, it isn't recognized. this is the main problem. i also downloaded rom manager, and it says i do not have root.
when i run start_root from the tutorial now:
