Samsung Galaxy S :: Battery Life Vs Usage
Aug 8, 2010
However, this simply has not been my experience at all, I get a couple of days out of my SGS whereas some others report only getting a day.
I just thought it would be interesting for us to post in here how much battery life we are getting for the amount of use we put the phone to.
There must be some sort of pattern.
My usage:
anywhere between 10 - 30 texts per day.
Several emails - sending and recieving.
a few phonecalls.
30 Minutes of gaming.
Twitter.
Live wallpaper running.
BBC News widget running and Weatherbug widget running.
I also listen to some music but this varies day by day.
3G and HSPDA are left on constantly as is my wireless.
GPS is turned off.
Thats my usage and i get at least a day and a half. Would be interesting to compare...

Since installing Froyo, and also doing a factory reset, my battery life seems much worse.
Also when I check what has been using the battery there are not as many apps displayed, typically just 'Display' and 'Cell Standby' even though I have used the web browser, wifi and Angry Birds.
Maybe the battery needs recalibrating with the new firmware?

I'd like to know the opinions various Galaxy S users have about this phone's battery life and their usage profile. I'd appreciate if you can provide me the following information:
1/ How long does the battery charge last between charges?
2/ What is your approximate phone usage profile during a day?
(Eg. 2hrs of browsing over wifi, 1 hour of browsing over 3G, 1 hour of video playback, 2 hours of audio playback/streaming while browsing etc.)
3/ Other useful information (Eg. signal conditions - poor 2G/3G coverage around my office)

As per this post, An idea for great battery life
Could someone with good battery life on a Galaxy S post their batterstats.bin file?
I'd like to try this fix and not sure if the batterystats file would work from the other thread since its a different phone.

I have had my Samsung Galaxy S phone (Samsung Fascinate to be specific) for a full year now, and it wasn't until just recently that i have been having battery life problems. I could get a full days worth and more in the past, but now, my battery has been acting odd. I would usually charge it while I was sleeping, then wake up and go through my day just fine. But now, the minute i take it off the charger, it goes straight to being only half charged, and this is after 5 or 6 hours of charging.

I propose that we all post our battery life graph like the one I am about to post below. This way we can look at these claims in scrutiny, and perhaps figure out why it is that some people's Evos seem to last longer than others. Here is a graph of my Evo's Battery Charge over 1 day:
Wake up at 7:30am to disconnect the charger, listen to Pandora on the car to work until I arrive at 8am. Idles until lunch time at 12pm. Use the Evo to read up on some news at lunch until 1:30pm. Listen to Pandora while working until 5pm. Drive home while listening to Pandora in the car. Battery starts giving warning indications while driving, and phone dies when I get home at 6pm. Very usual day, and matches what the battery charge graph shows. The top apps of the day are:
System Processes contains mediaserver (2.4% due to Pandora), akmd (0.3% accelerometer polling), and everything else is <0.1%. As you can see I barely used my phone during the day for anything but Pandora. So based on my data, I'd say that the normal battery life for the Evo is under 10 hours. My settings are: no 4g, no wifi, no bluetooth, yes gps, yes bckgrnd data, auto brightness, no live wallpaper, yes taskmanager (ATK, set to "safe" setting. Will probably get rid of this..), no friend stream, no flickr.
I'd love to see other people post up their Battery Usage graphs as well. The App used is "SystemPanel App / Task Manager", available for free in the market. Go into Settings and allow it to Monitor. The screenshots were made by ShootMe, also available in the market.

When my SD card is mounted in my Magic, the CPU usage is very high (90%+), the battery is very warm (34 degrees +) and it drains the battery very quickly (dead in 10 hrs with very min use).
When the SD card is unmounted or removed, the CPU usage drops to 10% or below, the phone is cool and the battery lasts very long.
Does anyone know the reason behind this and how it can be resolved?
I've reformatted the SD card and removed some of the media files not supported by my Magic but still have this issue.

We've all heard the horror stories (I just bought my Desire and the battery lasts for about 4 hours!) and the fanboy wankery (I get at least 3 days of heavy use!) So today I unplugged my Desire at about 6am and set off for work. It's 7pmish now and here's some stuff you may like to look at. I have 3G disabled, Sync on manual, no "live" widgets (just WiFi and bluetooth) live wallpaper (nexus) and screen brightness on auto. Here's the battery status (rounded up from 25% according to Battery Info in the Testing app)
The breakdown of usage:
My phone was idle for 9 hours and 45 mins:
The Display was on for a mere 2hours and 46 mins
With only 1.5 hours of WiFi:
And 30 mins of calls:
So, that'll be less than 3 hours of usage.

So when push email is enabled (for my exchange work email only) my battery drains 10% every hour, even if i don't touch the phone it drains 10% Is this normal?
Looking at my screen, the 3G icon in the notification bar is constanlty changing between a 3G and H and the arrows are lighting up all the time. I don't receive to many emails (between 1 and 5 an hour)
I have recently flashed to JM5 and have only had that problem since comming to0 JM5. I have tried to different tricks for restting the battery stats and calabrating the battery but nothing really works.

I installed the galaxo rom on my I7500L the other day and immediately encountered a problem. My battery died in less then 7 hours with the screen off. I read into the no sleep problem (and being able to tell I have it by not being prompted by lock screen) and do not believe I have that problem. I am running it pretty much bare bones, with adw launcher, advanced task killer, and handcent. I did have the task killer set to auto task kill and aggressive (turned it off completely now) that may have been the issue.
Although its particularly odd that every time I enter task kill the settings application is always open no matter if i kill it or not. Is there any common knowledge I didn't follow (heard of deleting launcher.apk cause galaxo constantly refreshes it) but haven't done so yet.
Allowing the screen to time out and using the end call button to bring it back on has resulted in the settings program not running in the task manager as it constantly has. scratch that, still doing it.

It's been 9 days since i bought my galaxy wonder.Its battery is too weird for 3 days.Because 3 days ago 2.5 hours passed until %98.Now once i unplug its charger, it downs to %84 in 2.5 hours
Why is it too unstable? I didn't calibrate. (If that means charging it 12 hours after it discharged for the first time, i didn't do it.May it be the reason?)
BTW, important note : All settings are off (Wi-fi,bluetooth,gps,syncronization) and screen brightness is about %30 or %35 i guess.I don't even use live wallpaper and only widget i use is battery widget.(A simple widget 100 kb)

My X recently (within the last week) started having extremely poor battery performance under the same usage conditions as the previous week (K-9 syncs every 15 min, maybe 2 texts per hour, 2-3 emails per hour, maybe 5 total minutes of phone use). After 4 hours, the battery would be at 20-30%
To make matters worse, most functions were extremely slow to respond (contact loading, test message loading, recent calls, bookmarks, any scrolling was choppy, etc.) The delay when trying the most basic things (opening the browser, making a call) was getting unbearable.
I started backtracking the changes in the last week. Although I started tinkering with Google's App Inventor over three weeks ago, that's where I focused. I uninstalled all App Inventor programs, including the Eyes-Free Text to Speech engine. This engine was recommended by Google to do things like read text messages in the Apps you create.
Still no luck.
I decided to investigate the battery use a little more. In Battery Manager, I found that "Android System" was using about 70% of my battery. I was typically used to seeing things like "display" at the top.
I have an app called Android System Info. This showed my CPU usage pegged at 100% (even after a reboot). It never got lower than 99%. The biggest CPU hog was "Android System" at 75-80%, consistently.
This App has a tab to view the log, and I noticed several recurring error messages in the log. They were occurring at the rate of about 180 times per second! The error? "Invalid TTS Engine" Well, the TTS is controlled by the "Android System". The "Android System" was constantly trying to load the uninstalled TTS engine.
I went into "Settings...Voice input and output", and, although the Eyes Free TTS engine wasn't available, the default TTS was not set. I checked the box to have the native TTS as the default, and checked the box for "Always use my settings".
Everything immediately went back to normal. CPU usage is now around 10-20%, and "Display" is back at the top of my battery hogging functions.
Battery life is back to over 10 hours, and the delays are gone.

Ive got the xperia x10 which I love now the battery problems are sorted but I've another upgrade due and had a quick play with the galaxy s today. Seemed pretty good but before deciding whether I should take it whats peoples opinions on the battery life and the camera? The battery on all my android phones hasn't been great but as long as I can happily get a day/day and half out of it with reasonable use i.e. bit of music, lot of texts, a little web and a few calls then id be happy with it. Also I notice the camera doesn't have a flash, what are the pics like people have been taking? I really liked the look and feel of phone but a little worried the amoled screen would drain the battery too much.

This is NOT a "my battery life sucks" thread, i'm just wondering what apps everyone uses to monitor their battery life and device usage.
I'm currently using:
Default Settings > Battery > Battery Use
Spare Parts
System Panel

I am getting a Galaxy S end of this week or early next week. Wondering how good it will be for VOIP. I am thinking of using either Skype, Fring or Nimbuzz in the background 24x7, connected mostly over 3G but sometimes (at home and at work) over Wi-Fi. If Wi-Fi is going to drain the battery faster, then I can have it on 3G all the time. I'm more than happy if I can get one day out of it. What do you guys think? Has anyone tried it?

I just rooted my Galaxy S Blaze and Got Rom Manager, Titanium backup which I have already backed up my phone. And I got SetPCU so my phone is currently over clocked I believe.
What roms could I get that enhance battery life? Or change the overral theme of my phone? I was expecting some drastic changes when I rooted

When you have the captivate plugged in and the battery is completely charged, does the phone then run completely off AC or does it continue to run off the battery and the AC just continually recharges it?

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.

How long does your battery last after "typical" usage? Everyone has its own special usage style, but just briefly say the recharging time, and what are used before charging.

I've been out of the Android game for awhile now. My first smart phone was an HTC Inspire and after that I jumped to the iPhone 4S. Well now I decided to go back to Android and I picked up a Galaxy S5 since I was impressed with my wife's S3. Love the phone, but I have one question that I can't quite figure out.
The AT&T Galaxy S5 has 16GB of memory. The available memory is a little over 10GB due to all of the bloatware and OS files, of course. Well I went out and purchased a 64GB MicroSD card and expanded that bad boy greatly. I moved any apps that I can over to the SD card and all of my music is over there as well. Well, here is the problem.
Out of the 10+ gigs available on the device (not SD), I only have 4GB free and 7.5GB used. I should not have that much space being used AT ALL. If I look at the My Files app, the graph shows that I only have 2GB of app data and no documents, 4mb audio (the rest on SD), video, ect. I only have 33mb of photos. I should have no more than 2.4GB used total. What could possibly be taking up so much space?

Well after trying evereything under the sun to get better battery life out of this vibrant, including atk, turning 3G off, installing battery apps, rooting, setcpu, lag fixes, now custom roms today. I finally know why the battery blows. I simply can't stop messing with this thing that is why! It's always in my hand like a nice comfort toy. Reminds of when the iPhone came out and I was hacking that thing to pieces updating unlocking jail breaking selling buying.

I have been having some battery issues on my Captivate and can only seem to get through 12 or so hours with minimal use and it is quite bothersome. The main reason I bought the phone was because of its battery life and so far, I am disappointed. For instance, I charged my phone all night, woke up and made a less than one minute phone call, looked at my status and I was at 96%. As the day went on with minimal use, it seems to drain without me even touching it. As of now (13 hours later), my battery icon is blue and showing halfway full, but the battery status says 36% which does not add up to me. I also don't have a live wallpaper and have Advanced Task Manager that kills all apps as well as GPS and Wifi turned off. Any tips? Should I take it back and get a new one or see if I can get a new battery?

I know this phone isn't know for blinding speed (at least running it stock), but lately it's having trouble keeping up with text input from the keyboard. Is this normal? I am using taskiller to kill any not needed background apps and normally have over 120mb left in RAM. Any tips on what I can do to fix this? I'm trying to hold off rooting until I get the t-mobile update. Also, does the phone normally give inaccurate battery readings to the widgets? Because I am literally looking at the phone and watching the percentage go up... up 6 percent in the last hour. lol anyone else getting this?
