Samsung EPIC 4G :: Battery Lasted 4 Hours?
Oct 20, 2010
I had bluetooth, 4G, wifi, screen on the brightest, 20 apps running at once, screen timeout at 30 min, and sprint tv playing, and it took me 4 hrs to drain my battery....is there a faster way? I was hoping I could drain it in like 2 hrs lol. I'm trying to condition my battery!

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 switched from eris to incredible couple days ago and loving this phone. Since many people are havin trouble with their battery, mine just lasted for 36 hrs with some heavy use; GPS navigation for 1 hr, music for couple hrs, texting, calling, foolin around in the market, instaling apps. If i did all tht on my eris, tht piece of shit would die in less than 6 hrs.
SO this phone is really good, i have had few signal issues but its bug so cant do much about it but the Battery which was my main concern has been really good.

I live in the central time zone. This morning I woke up and my phone decided to adjust for daylight savings time by 2 hours instead of 1. I checked the time and date settings to find that the date settings were checked to "automatic". Somehow the phone decided I was in the Mountain time zone instead of central. why/how that would happen? If I uncheck the automatic, and manually change my time zone it works fine.

Got the notice to update my system last night. At first it would not download at all. And then when it stated, it's been grinding away for over 10 hours! Anyone else experiencing extremely long update times?

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'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.

Many of us have experienced some battery life fall out since the last update. I mentioned this in the battery life thread but I thought it deserved it own topic. I have an app that I downloaded called battery status. it has a battery history. and it says time without sleeping 7h 10m 25s ago. Thats exactally when I unplugged my phone. This explains why I am seeing 2-3% per hour loss while not using the phone and while in airplane mode. Before the update I could keep the phone in airplane mode, not usre it, and leave work with over 94% battery life. So this proves that somehow the phone is not going into sleep mode... I can guarantee that everyone else in that is experiencing battery drain since the sept 16th update is due to this reason. The question is... why the hell is this happening and why won't the phone go into sleep mode?

Has anyone noticed an increase in battey drain while using the Lookout Mobile Security app? I noticed my battery drain was a little higher than usual today. I also have an app called battery indicator installed and was wondering if those apps cause higher battery drain also?

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've had this phone since day one and I've ran the battery down almost every day and only had minimum "low battery" alerts but tonight I am getting a warning flash on the screen every 10 seconds saying "Low Battery: Please Charge Battery". Seriously, every 10 seconds and it started at 15% battery left.so I have at least 30-60 minutes of life left.

Oops, forgot I charged in the car for 30 minutes.But this is still way better than before.

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 usually get bout 6 to 8 hours of usage before I'm in the red. Today I started a job and I haven't worked since I got my evo in june. From there till last night I havent put this thing down. Long story short, I'm a auto technician and my hands are always dirty so i haven't touched my phone but 2 times today. Been off the charger for 8 hours and I'm at 85 percent. At this rate I'm looking at 40 plus hours!! So there u have it, the secret to long battery life.

Does anyone know of an app that measures which apps use the most battery? I tried using various battery meters, including Battery History, BatteryLife, Battery Time, and others, but none of these seem to have this useful functionality.

Just picked up the Epic yesterday, and already been having issues all day long. The phone has does this about 5 or 6 times today. It will fade away, and when I come back to it a little later to check messages or anything, it will all be blacked out, and nothing will come back. (by hitting the power button) No matter what I push, the screen stays black, and the phone seems like it is off. (A few times, the lights have stayed on, and the buttons act like they are responding, but nothing works still) It has also lost signal completely twice today, and I've had to restart it to get signal back.

I am coming to the conclusion that the poor battery charge time is a result of the batteries and not the phone. The reason I believe this to be true is: I purchased the charger that comes with a spare battery and it takes a good 3-4 hours to charge in that, with no phone attached. Batteries in my previous phones would take an hour to fully charge in a dedicated charger. I bet when Seidio comes out with batteries for this phone, we will see much better charge times and possibly better battery life.

I've had my phone unplugged since 11AM this morning. It's now 8PM. My battery meter shows 1h 30m since unplugged (I think this is the built-in status from the OS). Additionally my battery widget shows 26% but the blue batter in the top corner shows 1/2 full. Are there any good battery meters out there that I can trust? Is anyone else noticing wild inconsistencies in time's and battery meters?

Battery life and Battery stability. I still cannot seem to get a good consistent battery life from my Evo. One day it lasts 10 hours the next I get only 5 hours with about the same usage time and its driving me bonkers. If I find the Epic to be more reliable with power management I'm keeping the Epic and changing over. Its all up to the battery now!

To find this, long press on the home button and then press the summary tab. There is a battery monitor at the bottom. Not sure how it works.

New user here. My battery life sucks and I seriously need help. I've had the phone for about 4 days, and I don't think I am doing too much to drain my battery at all. I connect WiFi and 4g only when available.After being unplugged for 2 hours, I am down to 85%. I have plugged in through USB and watched about 5 minutes of video, then disconnected. I've noticed that while plugged in USB in charge mode and doing anything on the phone, it charges only when the phone is on standby. It will stay at same percentage if I am doing something as little as navigating around the phone. I have 5 hours of life left according to Juice Plotter (free). I have Juice Defender (free) on and it says it has increased my battery life by x1.52. I have 4g off and bluetooth on. I updated my PRL. I toggled on/off Airplane Mode. Quit DRM. I also kill applications that I am no longer using so I never have more than 3 apps running in a short period of time.
