I'm having a really, really difficult time deciding between the HTC One, Galaxy S4, and Galaxy S4 Active.
Right now I'm mostly deciding between the S4 and Active. (why doesn't the Active have a 13 MP camera?!)
Anyways... I'm just wondering... Is it bad to run the S4 (AMOLED) at 100% brightness all the time?
It's really quite dim compared to the LCD screens (i.e. S4 Active) but at 100% brightness it's not too terrible.
Will the phone overheat or be damaged doing that? I've heard of the S4/S3 overheating quite fast...
I run mine at 95% or around that..sometimes it gets warm, but that is to be expected, hot, I haven't seen that yet. It does eat battery though.

Hey guys,
I am counting the days until the 1st November so I can purchase my Galaxy Tab.
I just have one question for you. What is the battery life like on your Tabs?
I have done a little maths and so far my results have told me that the battery life should be over double the life of a Samsung Galaxy S.
Maths:
Galaxy Tab: 4000 mah
Galaxy S: 1500 mah
Sinse the Galaxy tab has exactly the same specs as the galaxy s, the only thing I could think of that will drain the battery faster is the bigger screen on the tab.
Now lets pretend that the galaxy tab screen is 8 inches, exactly double of the galaxy s. Lets also pretend that the 8 inch screen makes the whole device consume 100% more than the Galaxy S. This means 3000 mah would make the device equivalent to a Galaxy S. That leaves 1000 extra mah!!
These figures are all over estimation so im hoping that it is double the battery life of the Galaxy s.
Are you guys getting these results?
for now im happy with mine
Mine is very good and i am a heavy user.
I can get at least 1.5 days out of it.
Seems good so far. I've been using mine heavily for last three days (typing this on it now) and it's been at about 40% battery when I go to bed and hook it up to the charger.
thanks for the info guys! sounds very good. I cant wait for november 1st!! so you guys think the battery is definatly noticebly better than the battery life of a high end android phone?
its not the best battery but better and can become more better with firmware updates
i have its since last saturday and i am getting decent 1 day battery with heavy usage
Yeah about a day on a full charge. By the way, could I have any problems from using a USB extender cable? The provided cable is pretty short.
Some days its ok, but days when I use 3G connection a lot the battery drains around 5:00 pm.
The battery life on my Galaxy-S phone is much better.
of course I use brightness on max most of the time...

Well,you can think of the issue this way: 8" diagonal vs 4" means 4 times bigger area.
With that said, you can not forget that it uses Super Crystal LCD vs SuperAMOLED
SuperAMOLED display is known as less power consuming than other, since it displays black without consuming power and works extremely hard showing white. So on black themes it is much less consuming than already bigger LCD the Tab got.
Third, the resolution itself. 1024x600 is roughly 2 times more than 800X480 which means twice as much processing power should be spent on exhibiting something on this already bigger, hungrier display.
So. If it was as simple as you think it should have last for a few hour using your equation.
P.S.
Mine is working 1.5 days with moderate usage.
it goes from 8 am to 8 pm but only barely. In fact I did run it down to 10% today. I will be buying a USB cable as soon as I can find one to plug it in in the office. I have 3G, WiFi and Bluetooh turned on all the time an run the screen at a decent brightness level though.
So basically, people with bad batter life have loads of things running (WiFi, 3G, BT) with high brightness.

Yep. Mine will last a full day from 7 am till 10pm. Using it to talk, video, browse and of course games. ..

Dear Friends and Community,
I recently acquired the S4 with moderate excitement. I already had a S3 and I was very happy with it but I had the option to get an S4 after extending one of our contracts so I went for it and gave my S3 to my wife - she's very happy with it now But i am not very happy with my S4 for 2 reasons:
- Extensive heat generation (36-47C) while surfing, watching videos, natigating calling etc.
- The heat seems to originate from the top portion of the phone on the back as well as the front side around the camera. it is uncomfortable to hold it against my hear on call
- My S3 did not heat up this much or this often. I also did not have any battery charge cliffs or jumps with my S3.
- As the device heats up, the battery drains INSANELY fast. Also I've noticed a disruptive and sudden battery discharge. As I charged my device for the frist time to 100% moments later the battery level jumped from for example 95% to 82% in one second. Is this due to battery calibration issues (because the device is new and the battery has not been charged many times yet) or is this something that can be considered a hardware flaw of the battery or device? I could be watching a video at medium brightness and my battery would go down by 1% each 2 minutes.
Sometimes during use and especially when it heats up some percentages are skipped while discharging (95%, 93%, 89% without sequencing down one by one but rather as 'chunks' of battery loss. ) did you exhibit similar behavior on your phone? Are these battery 'jumps' tied to the heat development?
And now the main questions: Should I return the device and exchange it against a new one or should I wait until Rom development or a patch tackles the problem ? I've already installed a recent OTA from Samsung and hoped the problem would vanish but no luck.
I'd be thrilled to hear your Opinions.
Best,
Thomas
Ive also noticed heating up and fast battery discharge, not one full day of normal usage, my s3 lasted at least 2 times longer. i hope it will pass as i finish 3 times battery charge discharge. for now im excited with camera quality and benchmarks scores i love this phone already, its still plastic but i dont care, with every phone i use silicon or other cases, for s4 i bought original samsung case with plastic back rounded by rubber.
In few days if overheating and fast discharge will not pass on its own i will flash firmware again with kies (repeir mode) and reset all settings.
I also experienced the same issue, its getting hot not warm while doing normal tasks... Dear Thomas u have see temp. in between 37 to 47 but my phone heats upto 55c while gaming... now my phone is with samsung service center, but i am not sure they will replace it with new one as their policy allows replacement only within seven days from the date of purchase and i bought it 27th April itself, just next day of launch. Now i am thinking that why the hell i rushed to buy it. i should have waited for user reviews...
And BTW flashing original firmware doesn't help. Because people at service center had done that and given my cell back to me, but that issue was still there so submitted it again to the service center.....
Are you guys getting these temperature readings using e.g. Battery temperature reading of Cool Tool?
My battery temperature as reported by cool tool never got above 40C but it felt quite hot to the touch already And I am not using any case on it...
I have a case arround it. I will play some games later to see where the temp peaks. but I think it will also be around 50 because it already gets pretty warm doing basic stuff like watching videos or using viber to call.
It feels like this is a problem for all S4's out there.
Check out this video at min 3:25 http://www.youtube.com/watch?v=aUx40kXZF5s (Steep drops in battery)
I really don't want to send in my device for no reason because I will most probably get a refurb or even a device with more problems.
I just want to know if other people have experienced similar issue.
You can check with the app called BatteryGraph and see if sometimes a few percent are skipped down the graph.
It would be great if someone did this for me
Same here with the heat. I undervolted -37,5mV and underclocked 300MHz, now everything is fine
Benchmarkscores are a little worse, but tbh, I really don't care. No current app or game is gonna use it anyway. Seems like a waste of battery life to keep the 1,9GHz clock speed.
Did the same with the Galaxy S2 I owned, which became quite hot too. Samsung has a tendency to overclock their chips just to outperform every other phone on the market, but the truth is, there is virtually no benefit in keeping the maxed clock speed in everyday use, other than doing benchmarks all the time ...
I think there's a serious issue with our phone's battery readings. Today I took the train at 8 am since boarding it have been using it, I also used it for 5 minutes before, it is now 846 am yet it shows screen on time of 30 minutes. Also when you restart your phone something goes wrong and the stats are totally wrong. Look at your stats now and reboot u will see that your screen on time is less than what it used to along with uptime.

I believe my battery isn't also what it should be. The thing is that it keeps overheating, which is much more power consuming. Not necessarily too hot, but hotter than I would expect it to get.
Most of the time around 32-35 Celcius, which in comparison to my constant overheated S2 is about the same temperature, but the S2 was busted, this is brand spanking new..
Even after flashing several roms, the phone still gets quite warm, which isn't so bad most of the time, but can get quite annoying when I have to make a call or something, and the phone is burning my ear off.
I guess it is something I have to live with until the next phone, but it would be nice if anyone could tell me a way to decrease the temp for just a little bit.
Post your battery life discussions here
I'm getting great battery on mine!
... Errrr, that was a dream I had last night. No edge for me yet.
Well i dont have the phone yet so i cant say to much.
but its only about 220mah less then the note 4.
It is newer tech tho and has a better battery saver then the note 3.
So my guess is the battery would last about as long as the note 3.
If the sidebar is able to display notifications/marquis stuff with the main panel off, then it would seem to make sense that during the course of a day you'd likely have a little less screen time, resulting in slightly better battery performance... thoughts?

True.
Just like how dark backgrounds give you better battery then light one.
This would be just a small part the the screen lite vs the full.
But to truly find out we needs hands on.
Samsung announced that battery charging is only 30 minutes For 50%
whether it applies when ON or OFF? since we know that charging while ON and OFF are different, while on its faster charging.
Current condition note 3 off charging at about 2 hours for charging 100%, and when phone on, a bit faster (do not know exactly) ..
how long charging to 100% while on and off for note 4?
but it was great news for 30m for 50%

You'll only want to do this occasionally if you want the battery to last long.

Yup, I think so. I prefer charging while phone off, because the battery last longer. But sometimes quick charging in a hurry really helpful, doesn't it?
What difference does the phone being on or off make on longevity ? Never heard of one.
And im pretty sure they mean while off. Unless the phone can be on at 0% lol. 30 mins 0-50% 99mins 0-full.
Source the Samsung unpacked after show video on YT
So I have the Snapdragon S7 Edge (AT&T) and I use hangouts probably 80% of the time I'm on my phone. Now when I do, the phone heats up significantly and performance and battery are very effected. Even if I'm just playing a game for 20 minutes or even a phone call, it heats up pretty bad. And I only get about 3hr of SOT. So do I have a defective device or is this normal??
Can't tell for sure, but from what I've read of the snapdragon variant, if anything, it just gets slightly warmer than the exynos, which even gets just slightly warm at heavy games, so I'd say you have a faulty device :/
Especially hangouts shouldn't have any effect on heat as long as you're not making long full quality video calls.

Mine is getting hot too without hardly doing anything. I'd heard that it was going to heat up when charging but this thing gets hot if it's on just browsing the Internet. It also really overheats when taking photos. I really don't want to have to get it replaced since I'm not sure what that will do to the already long wait for the gear vr.
How long have you had your device for? Mine only heated up the first couple of days but now it's almost always cool to the touch. The only time it gets warm is if I'm using the Gear VR.
