Samsung still claims 720 hours of standy time on the GS3?

[fr]

No F-ing way! I've been using it on the stock ROM for nearly 3 months and I've never gotten more than 36 hours of standby time before the battery goes down to critical (under 5%). Given, it's never been entirely idle for that entire period of time, but often I won't touch the phone for 12 hours and it's already loss 30% of it's battery.

 

[Suspicious-Teach8788]

i suggest someone trying airplane mode and letting it sit forever. I think you can get decent standby time, maybe a week or two like that.

Or maybe turning your data off.

I see people post like 2 day screenshots all the time but it's clear they did like nothing on their phones during that time.

 

[Muyoso]

I am sure that number is with no account syncing, wifi off, maybe even in airplane mode.

 

[Kanalua]

Yeah, I'm assuming this is in airplane more of with wifi and syncing disabled. When I upgraded to the Gnex I began using my Vibrant as a media play in airplane mode and I was very surprised at how much better battery life was! Would go days without charging.

I consider standby time to be the time it can standby waiting for a phone call. Traditionally that's what it's meant.

Therefore, airplane mode time is not what we should be measuring.

 

[ponyo]

I can easily believe that if it's in airplane mode. My original 7" Galaxy Tab is currently at 46% battery life after 19 days (456 hours) in airplane mode with WiFi turned on.

While I agree, I also see the reason why. Standing by for a call is extremely variable depending on signal strength etc... I wish there was a set standard but there isn't. 720 is kind of laughable, 250 that Apple says is also laughable. Neither phone get's that much time.

To get better times, try talk times?

You'd want WiFi on and connected, it uses less power than 3G and substantially less than LTE.

In airplane mode you have all radios off. This uses the least amount of battery other than shutting the phone off entirely.

Yeah but the WiFi still works. So you can still browse and do things you need to do other than make/send calls. The device is still on and ready anytime you want to use it. I consider that standby.

 

[Eug]

Airplane mode shuts off WiFi on the iPhone.

I believe it's the same on the Nexus 7, but I don't have it in front of me right now.

That said, you can turn WiFi back on, although that kinda defeats the purpose of airplane mode.

As far as I'm concerned, airplane mode with WiFi on defeats the purpose of airplane mode.

Airphone mode shuts off WiFi but you can turn the Wifi back on. At least that's how it is on Android devices. My original 3G 7" Galaxy Tab has the same cell radios as a phone and has full phone functionality. Like I said, I'm currently on 19 days on Airplane mode with 46% battery life still remaining. It's useful on phones/tablets with cell radio if you just want to use it as media device.

Nexus 7 is Wifi only device but you can still turn on WiFi while in Airplane mode.

 

[Yuriman]

Best standby I've had is 6 days with the cell radio and WiFi on with my GS2, that was 100% to 1% with practically zero use and a good signal the whole time. 144 hours is close to the absolute max I've heard from anyone.

 

[Eug]

Airphone mode shuts off WiFi but you can turn the Wifi back on. At least that's how it is on Android devices.

Yeah, I added that in my post before you posted yours. Same in iOS too.

But it does kinda defeat the purpose of airplane mode, at least on an airplane. However, I suppose airplane mode doesn't have to be used on an airplane, and can be used just as a master switch for all data transmissions. Turn on airplane mode to ensure everything is off, and then just turn on WiFi.

On my Nexus 7, I only have WiFi and GPS on. No Bluetooth, and it doesn't have cellular data anyway. Actually, I may as well turn off GPS too. It doesn't work in my workplace, and it doesn't work in my house very well either. Not that I need GPS in my house.

I've hit 5 hours of onscreen time with my gs3.why is it so hard to believe its getting amazing battery life?

People need to understand its not using a normal lipo battery its using a 3.8 volt one and it charges to 4.4 volts.my old nexus uses a 3.7 volt and only charge to 4.1 volts so there battery is filling up with more power meaning a gs3 battery is like charging a nexus batter to 120% and over charging it.

We get about 2 hours of use on a full charge and if we could fit our battery in a nexus it would show it being 100% full since it charged over it speced battery settings.

I've hit 5 hours of onscreen time with my gs3 and the app power draw is bugged up but the actual total usage is OK.

I watched the hunger games on it and that took up 2.3 hours of screen use alone

How has anything you've said convinced anyone that you can hit 720 hours of standby? We know standard smartphone users charge every night. Even with great batteries like in the SGS3, my gf will go to sleep with like 30% battery. Ok, so say she does get up and use it the next day til lunch? Is that 720 hours?

Ok now let's say she starts turning off stuff and stops using her cell phone. Even if she squeezes 3-4 days out of it which probably less than 1% of smartphone users even achieve, is that 720 hours?

No.

Also not sure why people are saying Airplane mode + Wifi. Just syncing alone is going to drain battery. Maybe you guys get 2 emails a day or something, or don't sync anything, but if you sync Twitter, FB, Gmail, work mail, even wifi isn't going to save you.

 

[grkM3]

I have all syncing off and manually refresh email and don't use twitter of Facebook app.I just use the browser and if you shut data off and let the phone sleep for 720 hours it will ring when it gets a phone call.

I don't think anyone thinks a cell phone can have 4g connected synced standby with emails and social media alerts being pushed to it last 6 days.but it will if u let it sleep with late and 3g off and just using the radio for voice calls.

I also disable GPS and only use it when I need it and the fb app is notorious for killing battery life.every time you post a status it searches and locks your GPS to tag your location in the post.

Tell your gf to turn all that crap off and see if it gets better life out of it.

If you make a post that can take like a minute tops. A minute of GPS use isn't going to kill your battery. If you make 60 Facebook posts a day on your phone though.... I mean I'd argue iPhone users probably have the same location services enabled by default, so unless Android's GPS eats 10x the battery or something, I don't see this really being the killer.

For me, I see the top wakelocks being:
- Google Latitude
- Google Talk

Latitude not only uses location services, but if your data connection sucks, trying to grab location via cellular data and continuously trying to communicate with the server will ruin your battery. GTalk pushes all day long and certainly is a drainer too.

The gs3 has a GPS locking issue and it wintvstay locked so Facebook is making your gos try to relock every time and it will show the searching for GPS for like 3 min and most times not even lock.

Verizon finally admitted there is a GPS issue and there is an update coming from Samsung in the next touch wiz jellybean build.

Its sad that my gs3 right now for the life of it lock its GPS and that is why I keep it off.there are hundreds of posts over at xda with users blaming custom cm ROMs from having GPS not work but now we are seeing perfectly stock phones not locking.

I just read on the latest jb tiuchwiz leaked ROM that people are locking gps fine and looks like the issue has been fixed.

I also don't use lattidue and that crap will suck power like no other.

I use the browser for twitter and Facebook and have no need for spps to be awake and keeping the cell from deep sleep.

 

[vshah]

i don't doubt that you could get to 720 hours in 2g, with no data enabled, screen off, no apps installed, perfect signal strength etc. but that's not really realistic usage for a smartphone.

 

[pm]

The big manufacturers seem to quote the absolute extremes. You get worst-case usage - "talk time" and "movie watching" - where they are continuously using that capability, and you get the absolute best-case usage “idle time” where data is disabled and nothing is going on at all. The problem might be that it’s really hard to describe typical usage and having the manufacturers try to quote a number opens themselves up to charges of false advertising. You might say “720hours of standby is false advertising” but I would bet that they have factual laboratory data showing that number to be correct – misleading, but correct. But if you say “you’ll get 24 hours of typical use” then you end up with all of the different apps doing different things in the background and one person’s typical use is very different than anothers.

 

[MrX8503]

Apple actually lists realistic/typical specs. 720hrs was probably the extreme.

 

[Zaap]

I don't need or care about any 720 hours of standby time claim.

But the SGS3 does get excellent battery life. If dicking over the 720 hour claim makes people feel better, then so be it, but it doesn't change anything.

And the battery is easily-swapped which makes that whole dumb pissing match moot anyway. Like it's funny to me times when my friends forget to charge their iPhones and have to leave it charging. The whole battery life issue is 100% MOOT when your damn phone is sitting somewhere charging, or tethered to a charger cable, instead of you being able to walk off with it and use it.

My SGS3 never will put me in that situation because I can just pop the back off, install a fresh battery, put the spent one in the charger cradle, and off we go. So great battery life + easily swapped anyway = STFU already with the pissing match.

Uh ok.

The SGS3 is fast. If dicking over the 32 core claim makes people feel better, then so be it, but it doesn't change anything. Is that better? Is it ok for Samsung to spec 32 cores?

A spec is a spec. It's one thing if you quote extreme specs, and another if you quote realistic specs. The federal government makes sure mpg ratings are based on some fair assessment. Would you like 150 mpg ratings that were obtained coasting downhill?

Not everyone wants a second battery or wants to carry a second battery on them all the time. Furthermore, a second battery requires a dock charger in order to effectively use a 2 battery solution--unless of course you love charging your phone then swapping batteries and charging it again (a bit inefficient IMO). I appreciate a 2 battery solution, but a spec is a spec.

I really don't see the reason to start insulting iPhones and getting extremely defensive about a possibly unreasonable spec.

Likewise, the iPhone 5's 225 hours standby is a bit high too, though only 1/3 Samsung's claim. I'd love to see people challenge that too.

But given the nature of Android and syncing and pulling data constantly, I find it harder for the average Android user to get as good battery life as an iPhone. You would have to work hard to disable a lot of syncing.

You're busy playing team-sports. I don't give a rat what Samsung claims, or Apple, or anyone else.

Good for them, then they can CHOOSE not to, as opposed to have NO CHOICE not to.

This doesn't make any sense. Batteries for the SGS3 are a dime a dozen- many of them are higher capacity than the stock, meaning that easily much higher charge times are possible than the average amounts claimed. (And again, I don't care about the corporate hype theoretical limit claims) and I can take as many with me as I may need if I were to be in a situation where I need my phone for periods longer than it would take to charge it.

There's ZERO phone downtime with an interchangeable battery, where with an iPhone there's guaranteed time where you have to leave the phone to charge, and any other solution isn't as good as merely swapping a battery.

Often there's time where my wife will use her iPhone all day at work, come home, and it's pretty much done, but then, hey, let's go out to a social function. She either has to leave her phone tethered, or carry it with her with the near-dead battery screaming for a charge, having no idea if it'll die on her. Meanwhile, my SGS3 is NEVER in that situation, and never needs to be. Battery life means DICK when the phone isn't fully charged and is toward the end of the cycle, and yet you still needs to be using it for unknown hours longer; it's just that simple.

I really don't see the reason to start insulting iPhones and getting extremely defensive about a possibly unreasonable spec.

I don't see the reason why you're trying to make such a big deal out of a spec, when the specs of the phone are awesome, and no one really needs some unrealistic 720 hours of standby time.

Likewise, the iPhone 5's 225 hours standby is a bit high too, though only 1/3 Samsung's claim. I'd love to see people challenge that too.

Why? Again, who really cares? Both are obviously just extreme examples that you'd probably need a lab to reproduce. Every other tech company, with every other tech product makes the same sort of 'non-real world' claims. People usually don't get too worked up about them one way or another unless they're caught up in the usual team sports nonsense.

But given the nature of Android and syncing and pulling data constantly, I find it harder for the average Android user to get as good battery life as an iPhone. You would have to work hard to disable a lot of syncing.

This makes no sense to me. What constant syncing and pulling data constantly? My data connection is never turned on unless I need it. On wifi, the SGS3 has a setting to turn off wifi as soon as the phone sleeps. That's even if Tasker or JuiceDefender or other settings weren't already handling that sort of thing anyway.
