Got my SIII A few days ago & I love it. I wouldn't say I have any problems with it, but just wondering if any of you are experiencing what I am. So first thing is battery life, It takes about an hour, maybe an hour & a half to get fully charged when it's about 5% battery life. My son was playing games on it last night starting at 100% (Wifi was off & screen brightness was at about 5%) & he played for about 35 minutes straight, the battery life got down to 80% after those 35 minutes. Does this sound about normal for the battery life? Also, I watched a few Youtube videos about this phone & Some users asked the S Voice a question like "How many days until christmas" and the answer it gave was the right answer. Now I asked the same thing, but it said "I'm sorry I don't have that answer would you like to search the web" So I'm not sure why It didn't give me an answer like it did for the guy on The video. Not sure if it's Just different Providers Or what. I have AT&T by the way. But just let me know how your SIII is doing & if you have any tips to save battery life or anything else. I usually have wifi on when I'm at home or school. When I'm inside my brightness is usually off or barely on. Power saving mode I also have that on. I use my Task manager to Close unwanted apps. I just wanna make sure this is a normal thing for the SIII, don't think mine has a defect but still, just curious. Thanks

What I do for some reason because I think it really does something, I put it on the charger every night So it will be full in the morning. When I wake up, I turn the phone off, still leaving it plugged in. Do what I do to get ready in the morning, when I'm done I turn the phone back on, make sure it's at 100% When I take it off. I use my Task manager and close all of the apps. I go into my apps & force close any running apps that I am not using or don't need running. Honestly, I don't know if this really helps or anything but I've been doing it before my SIII. Does anyone else do this?

I do it sometimes because I am afraid an app is running in the background when I don't want it to, but it's been well-discussed here that this procedure doesn't save any battery and probably costs some. Android is very good at stopping apps from using battery once you've switched apps or returned to the home screen. It keeps the apps you use most loaded into memory, and if you close them with the task manager then (1) it will be confused about the apps it should keep loaded, and (2) when you open those apps again it will take battery and time to reload them.

What is important, though, is to be aware of all the apps you have and which ones sync. You should set the sync rate for those apps to the lowest number you are comfortable with. So, for example, I set my Facebook refresh interval to "never" (it synchs when I go to the app), and my email only syncs when I press the sync button. I also disabled a bunch of Samsung apps and removed my Samsung account so it won't sync.

Can you explain what are the Samsung apps and account? Perhaps you're referring to Google apps and account? I have the Samsung Galaxy Nexus (gsm) which may explain my confusion!

It's mobile data that's doing it. The rest are negligible.

After reset notice a difference after a few hours. My battery life almost doubled and I have no idea why a reset would do this but very happy with battery life on the s3 now.

Thanks dude. I tried this and I find that my battery life is a lot better. I slowly started installing apps and so far so good.

One thing I have noticed though is that I havent put any music on my phone yet and I noticed using GSAM that mediaserver service was holding my phone awake for 1h 48 minutes after my phone has been on for like 20 hours+.

I dont know if it matters since my battery life is better after factory reset but seeing that mediaserver is keeping my phone awake for more than an hour wasnt sure if that was normal or not

Thanks

My held awake time is 1.8% - But it's the middle of the day.

So do I need to check it after a night?

I have looking at this battery thing a little bit seeing if I can eke some more out.

Downloaded the infamous GSAM.

I charged yesterday and left overnight without really using it.
A few text, emails etc.
I did the tip of charging fully and then unlock the screen before removing the cable as there was a suggestion this may cause an issue with wakelock.
Anyway.

I left data, email, notifications on.
I only reduced the volume to vibrate.
I had 2 gmails at 3:38 in the morning and my phone was flashing at 6:50.

I took a few screenshots.









These last one was interesting as it appears to me to show that WITHOUT a good signal, it doesnt use much battery?

Maybe something is running in the background causing it to wake and not deep sleep.

If you look at my Third image, View Num Times Waking Device, the weather app has fired up 18 times, once per hour as my settings.
Check yours and see if something looks out of sync.

Its certainly a place to start.

Just think in your own mind "in those 42 minutes it been on is the 45 times related to eBay too much"
What I would say, in my limited experience, don't start removing everything in one go cos you wont know exactly what has changed.

Change one thing per day and give it a test.
I haven't used the blocking mode yet (to reduce power and connectivity overnight) as I want to see what effect these other things have.

Wondering if people can help me analyze this. I unplugged at 100% around 7pm. Now at noon the following day its dead. Little use last night. Overnight it lost a little over 10%. Below average use throughout the day, no Wifi, no email checking. Am i getting good battery life, or at least average? I should be getting above average with my use today. 16 hrs of battery life this charge.

Bigger questions: Why did the phone radio use over 45% of my battery?! poor service? And why the hell did the system, google services, and maps wake my phone for a combined 380+ times? everything else is negligible.

You need to pull up the graph of your signal strength and check the timeline against your location. My signal at home is crap, even on 3g which I can compare directly with my wife's iPhone 4.

With the first screenshot, click on the second icon along the bottom to give you the graph, these should show you the signal strength. If its poor signal then maybe there is something there.

i plugged in my phone so the graph reset. or did it? i dont know exactly how this app stores data. anyway, i just switched from an iPhone 4 and i frequently had little to no reception in my apt. Now with my GS3 i have fantastic reception... but apparently, at what cost? lots of battery life i suppose.

Alright here are two shots. Looks like while i was sleeping it just flatlined at a medium reception? Im not really sure what the reception graph implies.

second ss just reinforcing cell usage. very annoying that its so high. why is it so high?

I'm having a similar problem with my signal. After 9.5 hours at work with a consistent decent signal, I come home with 40% of my battery remaining which I figure should last me the rest of the night since I'll switch to wifi and not use it much.

But then apparently the signal jumps all over the place which is causing my battery to nosedive and need a charge a couple hours later. It doesn't make much sense since I work a block away from home, and when I look at the status screen at any given time in both places, it says similar numbers. between -88 and -92 and 54 asu. I've been in spots that are worse than -100 and according to gsam, it doesn't jump around as much as when I'm home.

If you look at this gsam shot, the parts where it plummets are the parts of my day where I'm home. In the morning, half hour lunch, and at the end of the day.

If you look at the history screen shots, you can see that when I'm home (the times where wifi is on), the signal bar goes from solid green to yellow, etc and back to green repeatedly.

The Verizon store guy thought it was completely normal, and said Samsung antennas suck.

Just to make you sick!



Ok, to be honest it lasted a whole weekend. I didnt use it much apart from a few emails and texts etc.

Dennygreen, I check mine just now.



You seem to have a lot of awake time. Mine is much less awake maybe meaning that yours isnt going into a deep sleep.

Anyone else got any inspiration?

yeah I don't let mine sleep at all. Pretty much from the time I take it off the charger in the morning till I'm done with work its doing something. podcasts, music, texting, browsing etc.

I'm just kinda annoyed that the battery drains so much faster at home on wifi with less use than at work on lte with a lot of use. It seems to be a result of this jumping signal thing.

hmm. thanks. yours looks like it's kinda all over the place too.

I wonder if there's a better app for measuring this stuff in better detail.

Hello guys. I'm a noob here and just wanted to say that I have had my s3 for about a month, have downloaded Juice Defender Ultimate, Gsam Battery Monitor and have read every message in this thread and followed the suggestions where/when I could and now average a hair under 27 hours of battery life with moderate use. Am I wrong in thinking this is pretty damn good? Should I strive for even more life? It is not really needed as I live in Houston, Texas and am never away from a charging plug for more than a couple of hours at a time anyway.

I can't respond directly since I haven't done any long-term tests. I like to test the phone overnight when it's not being used. I find that with JDU, the battery drain is in the range of 0.3-0.4 %/h. Basically, I run the test by fully charging the phone then unplugging it and turning off screen. In the morning I start it up and check GSam first thing. I suggest trying that and seeing how you compare. The results are considerably better than running the same test with JDU disabled. As near as I can tell, I don't have any misbehaving apps. I'm using BetterBatteryStats, Watchdog, GSam, and BatteryMix. They all provide useful information.

For purposes of comparison, you might want to describe your JDU configuration

Nothing special on JDU. Just the basic balanced setting. I wanted to test a few times to see how that setting did before I jacked with it.

Question

A number of times it's been mentioned here to reduce the amount of times that the apps like Facebook etc... sync. I would love to do that but can't see how!

Sorry for my ignorance but could someone please give me a step>by step>by step please?

For Facebook:
- Run Facebook
- Click the Menu button on the lower-left corner of your S3
- Select Settings (gear icon)
- Select Refresh interval
- Select an option
- For maximum battery life, you can choose Never, then each time you run Facebook, pull the screen down for a moment, then release, and you should see your feeds reload.

Many apps follow a similar principle, but they usually call it "sync" and not "refresh".

Another place to look is your phone settings' Accounts and sync:
- Pull down your notification screen (from the top of the phone down)
- Choose the "gear" icon on the upper right
- Scroll down and select Accounts and sync
- This will show you what accounts you have that synch. You can examine those accounts and make any changes you'd like to try out.

Thanks, sorted it on the Facebook App, but I don't have an Accounts and Sync menu path any more since I updated to JB 4.1.1.

When I go into settings, I scroll down and I now have a section called "Accounts". In that section (but without having to press a button) I can see the apps which I assume require Syncing, pressing the menu button here does nothing so I'm left with going into each app. Unfortunately, a lot of the apps don't have sync options as far as I can see, (e.g. Twitter) so I assume they're just push applications?

Also, I don't see Gmail listed and doing your steps in Gmail doesn't really help me out, so I assume that's a push app too?

Thanks for the advice, hope I'm not hijacking a useful thread, if I am let me know.

If you don't see any controls in your Accounts settings, then you can run each individual app and press the phone's Menu button to access that app's settings.

There has been a lot of speculation here that push Gmail is better for your battery than having your email program "poll" the Gmail server periodically.

There's an excellent, free app called Gsam Battery Monitor. It will give you a breakdown of what components of your phone used your battery since you pulled it off the charger (or you can put in a new starting point manually). If you run that, you'll see what apps are really using your juice. It will say something like App Usage...56%, and if you touch App Usage it will show you a breakdown by app. If you see an app near the top of the list that you haven't been using that day, you'll know it's been syncing.

But I don't know if the opposite is also true. I.e., is is possible for an app to use the phone radio for syncing but not show up high in the App Usage list as having used a lot of battery? Maybe others can address that point.

That's fine. The beauty of running the test described above is that you eliminate variability caused by things such as screen, phone calls, etc, but highlight any misbehaving apps. In other words, it provides more of an apples-to-apples comparison.

Cool, my battery is pretty good to be fair, about 25 hours. I had Gsam but I'm only after realising that I could go to the App Sucker and click on the top right drop down to see where my wake locks were coming from. Turns out eBay (which I promptly uninstalled) and my maps (because I have location based services turned on) were draining my battery the most, I'm happy enough leaving on my location based services. So that's cool. Thanks!

Default Phone radio

Hi Guys,

I have installed GSam battery monitor.
I notice that "Phone Radio" uses over 80% of the battery.
What is that Phone Radio?
Is it possible to close that process?
Please let me know how to reduce Phone Radio's Battery usage.

Take a look at the screenshot below,

mpadhu, click on Phone Radio and it will take you to a breakdown of how strong your signal strength has been.

If you have a weak cell signal, your phone will use lots of battery to stay connected. You can try turning off mobile data on the pull-down settings screen when you are in an area with very weak signal to see if that helps with your battery life, but you won't be able to receive text messages or use Internet functions unless you're on wifi.

Turning off mobile data only disables MMS not SMS.

Ok, thanks for the correction. What's the best way to deal with a weak cell signal's effect on the battery while still being able to be connected to wifi?

As mentioned a few times, the GS3 has the best battery life of the many phones I have tested with medium to good signal. The bad thing is it easily has the worst battery life with a weak signal.

It gets so bad in weak areas it would be nice if there were an app that would dynamically turn off the data radio at a certain signal strength threshold.

It is a great device, but has gosh awful power draw in weak signal areas. As example, the Incredible, DX2, Droid 3 and Razr also drained more with weak signal, but the GS3 is in it's league of bad compared to them.

I've heard that the GS3 power drain/cell standy issue is fixed in JB 4.1 but obviously I cannot confirm yet. But yes the GS3 has serious cell standby problems.

I have had my phone for three days and battery life has been awful.

Today, I have used less than five hours off a fully charged battery and I'm down to 80% with little usage.

My battery shows 38% from android and 33% from screen. I have the screen set at 15%.

I live in Maui and have everything from decent to bad reception. I'm wondering if my battery drain is because of reception issues.

Very frustrated and discouraged.

It's karma, dude. You are being punished for living in Maui while the rest of us do not.

If your average reception area is weak, that is a big chunk of the issue. Turn data off just to test if true or not.

Dude that is not that bad. You probably have something running in the background.

I'll run the battery monitoring app when I get home and see what is happening.

But while I'm typing I have lost 1%.

Ever since I updated to JB, the "Media" is using up to 40% of the battery. Any ideas? I have a feeling Google Music is the culprit.
