Battery Life

I get to around 75% after 16-hrs (morning to night) Using Juice Defender with Root and Most of the Options used. That being said, I have Bluetooth on all day, wifi on all day, NFC on all day, Maybe about an hour of screen use. I'll post my battery usage pic tomorrow.

My juice defender profile is quite aggressive though with no loss of functionality.

I could probably last 2 days without a charge.

I've experienced excellent battery life with regular use throughout the day. Talking Gmail, 2 push email accounts, watching YouTube, FB, Twitter, G+, streaming music...all that and plenty of juice for well over 12 hours.

I've had the HTC Aria, Motorola Atrix 4G and Atrix 2 and now the Galaxy SIII...even with the beefier processor, it has the best battery life out of the box, of the Android phones I've used.

This is really frustrating. One week my phone was literally burning up the battery. I mean it felt warm in my pocket when I pulled it out. I couldnt even make it half a day before I got a low battery warning, and I didnt even have push mail installed yet. Then, after the AT&T OTA update it seemed to get significantly better...maybe it was a placebo effect.. I installed push email and with autosync on it and gmail and was doing a decent amount of browsing as well and battery life was great.. I was shocked to see by late in the evening I still had over 40% left. Then this week my phone is back to burning a hole in my pocket again. I unplugged it at 630 am , used Tapatalk for about 10 minutes while in the "library" and my battery dropped all the way down to 89%. By 10 am at work I got the low battery alarm and had to charge it. I have power saver enabled, low brightness settings, Juice Defender installed but still its discharging like a mofo.... here's my screen shot..

Of course, but AT&T actually at least in FL had an issue with iPhones being able to go on 2G networks.

About 2 years ago, there was a small 3G outage. Parts of the 3G network were still up, and most phones worked on it fine. The full 2G network was up perfectly. What happened was in South Florida most people with iPhones ended up switching theirs to the 2G network for calls, and it took down the rest of the network.

The reason for this was that AT&T had started to cannibalize their 2G network for their 3G network (because of limited spectrum). They had reduced capacity, and while the phones were smart enough to work with what they had on 3G the moment people started to force their device to the weakened 2G it ended up taking down more of the network.

AT&T has already started cannibalizing parts of their 3G/2G network for LTE. Since they are backwards compatible it's not the end of the world, but that's my belief on why AT&T has prevented us from doing it. It's not exactly "right" but it does prevent network issues getting worse when something happens. It's better to have a crippled network than have a network completely and totally comatose.

How should I charge my battery?

What is the right way to charge the battery the first time you get the phone? I heard so many different opinions, should I let it die then fully charge it all night? or fully charge it when I get?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] jasvncnt1:
I just fully charge when i got it then let it run down to like 5% or so. Then fully charge again. I do that like 3 times. Then i dont worry about it. Thats just me though.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] ewingr:
I dont' know. If all your phone is doing is sitting there in standby, it makes sense that will be the highest measure.

I first try to decide if it is drawing too much power. Per my post earlier, I measure how much I lose per hour, while in standby (ie no varying user intervention), then compare as I make changes to things to try to improve it.

I was thinking battery life was pretty bad. Then I tested, and 1.11%/Hour with Wifi, GPS , and BT all on, I think that is pretty good. Although not as good as I hope to get with some future kernels.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] yokken:

[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] vinuneuro:
I was hoping for better. ATT version seems to be around the same or only marginally better than the ATT One X. Why is this despite the larger battery? Will non-oem rom's fix it?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] mastarifla:
It took a year for Samsung to optimize the software for the S2, so yes it will get better with time, and I am sure the developers can tweak a few settings as well, so I wouldn't worry about it.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] modestprophet:
After my first complete charge to 100% it took ~ 13 hours to get the battery down to 1%. This was filled with pretty heavy usage (Facebook, Words with Friends, internet browsing, installing apps I like, testing GPS, Wi-Fi on the entire time and about 2 hours of Cartoons Wars 2).

The battery life is a SIGNIFICANT improvement over the SGS I (T-Mobile) that I prior to the SGS 3.

I have noticed that there seems to be a long time gap between 99%/100% to the time when the phone actually tells you to unplug it from the charger.

I have seem some talk that the SGS 3 takes a really long time to charge. One reason might be because of the much larger battery capacity in the SGS3 @ 2100 mah. Most SGS 2 variants had 1800 mah batteries and I think the SGS 1 was 1500 or 1600 mah. Bigger battery = bigger gas tank = longer time to fill it.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] ewingr:
I just did another low usage test over night. In fact screen time was very low, at 1 hour 25 min. I like to get a general feel for battery standby usage.

It came out at .905% / hour. That's less than 1% / hour (just in case you didn't see the decimal). My Captivate, when stock, would use 3-4% / hour.

My next test will be to see how much screen time I get.

I'm not sure why maps shows time...I don't recall using maps.

BTW...looks like charging is relatively fast for me. I've had it plugged in now for maybe 30 - 45 minutes, and it has gone from 35% to 71%.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] lensgrabber:
I'm pretty sure maps is loaded at startup. Both my nexus and prime have maps as running apps regardless of if I launched it or not.

So the initial reports were that battery life was not that great. I'm assuming now that after a couple of cycles everyone is, for the most part, happy with battery life with the device on LTE?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] naturefreak85:
On the topic of maps....do you by chance have Latitude turned on?

---------- Post added at 11:15 AM ---------- Previous post was at 11:15 AM ----------

If I had full LTE in my area? I could say for sure, right now there is 1 maybe 2 towers enabled in my area, that's leading to switching between the two often, which ends up draining the battery faster.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] ewingr:
Oh, by they way: the above times for overnight was with APN turned off. (I am not in an LTE Area). As noted, that used 9.05% / hour. My first test was with APN on, and it used 1.11 % / hour.

I haven't even looked at Latitude, so I wouldn't expect it to be on.

Exchange service

I get good battery life, but I noticed when I add my work exchange account, I huge decrease in battery life, and very high data usage from exchange accesses (After 3 days it was using 208 MB of data (no attachments on my emails), and was responsible for 35% of my battery usage, more than even the screen)

I had to remove the exchange email account from my device, and now my battery usage and data is back to normal. I did a few searches and it seems that what ever Google did to "update" their exchange services for ICS really screwed things up.

I just woke up so I'm too lazy to provide a screenshot right now.

I get around 16 hours before it completely shuts down. Mind you, I have a SetCPU profile activated at 80% battery life that will reduce the max CPU speed to 800MHz and min CPU speed to 500MHz. I do use the phone, messaging app, music player, and several other social media apps during this time period. Also, LTE is always turned on whenever I'm out of the house. Gaming or watching videos while on this profile will be less responsive and choppy on video streaming.

I've also tested with 1.2GHz max and 800MHz min activated at 100% will provide the user with more gaming functionality without sacrificing performance or experience any choppy videos on Youtube or video streaming.

I don't do much gaming or intensive browsing on the go, so I've found that this low CPU speed profile is suitable for me.

Unreal battery life, no cheat.

So I got over 2 days on battery including more than 5 hours of screen time, this include around a couple of hour of browsing, a couple of hours reading a pdf and 1 hour of misc use, there was around 20 min of phone calls too. The first day was at home, with Wifi, while the second day was on the go, so I disabled Wifi. This is not ‘heavy’ use by any means, but truly exceptional battery life nonetheless.

I am on stock battery and running Triune II ROM with the stock kernel and I have really scrubbed the bloat that I do not use (Samsung, AT&T, DLNA…)

This is an AT&T phone, but I am currently in Europe (France) roaming on Orange, they do not have any LTE deployment, so I assume that the APN is possibly disabling the LTE radio and leading to some massive battery gains (?). I had great Battery life in the past under similar condition (AT&T phone roaming in Europe), but not as good at this time.
