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. ..

Cheers everyone,i have a problem with my battery-it is draining too much power in standby mode.I flashed 7-8 roms(both sense,aosp or cm7) and with all of them the battery drains 31-34mah .I know this is not extreme,but i don't think its normal.My SGS drains 2-4mah no matter the rom,my hd2 drains 7-9mah with nand android.
By night,when i sleep,battery goes down from 100% to 78% (that's 8 hours)
As i said,i tried many roms,i changed radio,too.
For info my g2 is s-off and dz hboot.
Any suggestions?

Mid 30s mAh is the lowest I get with the G2. That's my battery drain if I have good, consistent reception or if I'm connected to Wi-Fi with wifi calling enabled.
With my average use (a good amount of texts, whatsapp messages, emails, small amount of web browsing), I'm down from 100% to low 60's or mid 50's at the end of the day. If I don't charge at night I can get 40 hours on a single charge if I am very conservative.
That being said I really don't think you can do any better, nor do I think your battery situation is anything to complain about. Regarding the the other phones with 2-4 mAh, I have read of those kinds of readings for other phones but in the end the battery life in terms of hours is similar.
I'm 32mA on standby, I seriously doubt the 2-4mA reading, old nokia's drew more than that.
Only advice I can offer is breaking your battery in if new or purchasing a bigger battery. I was pointed to 1600mAh Anker batteries recently, around £8 on amazon uk. Just waiting on delivery though I am reasonably happy with the stock battery, get a around 24hrs on a typical day.

2-4mA is the drain of the SGS.My battery record with sgs with stock battery is 3 days and a half with 8 hours display ON.I could never get that battery life with my g2.
I noticed a significant drop in battery life when I updated the latest version of google Maps. I wish that I could back out to a previous version. A normal drain for me prior to the update was minimal (say a quarter of the way on the icon) for an entire day's usage of phone and various apps and texting. Now, my battery drains down to YELLOW stage even if I'm only on Stand-by mode.
I am running the latest stable version of CM7 and had absolutely no problems or significant negatives until this gMap update.

That's impressive! I hadn't heard anything about such good battery life for the SGS. Makes me wonder exactly is the cause of the vision standby drain, with all the internal components current draw & screen off, I would have thought maybe around 10mA would be reasonable.
Hmmm.

I think samsung just did a better job than htc in terms of battery.Ofcourse,these 8 hours display on,are mostly with dark colours,i read books with white text on black blackground,maybe this is what extends battery life on the sgs so much.Yet,even if so,sgs has better battery life.
Remember were talking mili amps here ppl, I doubt anything can survive on 2mA...js

I don't want to ruin the moment... but any info about battery life on Nexus 4?
I don't want to waste ~u$s360 with a device that longs 4/5 hours...
Thanks.
And how are we supposed to gather this type of information?
Wait for hands on reviews!

According to gsmarena, it has a 2100 mah battery

Yeah, the big downside of a non-removable battery is the inability to upgrade if the battery life sucks. I can go over 24 hours on my Sensation with moderate use thanks to the extended battery I purchased for it.
It's a far cry from the GNexs 1750mAh battery, the 2100mAh battery in this should last a little longer.
I heard somewhere (for the life of me I cannot remember where) that it has somewhere around 12 hours talk-time. Of course that's yet to be confirmed...
well your basically getting a gnex with 350mah extra battery. and this time they are using a Li-polymer battery instead of the normal Li-ion so the battery will not degrade in about 2 years it will still hold a good charge.
anything's better than the iPhone 5's 1700 mAh batter
As seen in the pdf manual, there are only two little screws keeping you from removing the battery

1440 mAh.
That said, it's not only about mAh -- the iP5 holds pretty close to the Maxx from a lot of reviews.

Exactly. But Android phones, particularly the high-end ones, require an added boost. The iPhone 5 doesn't need the extra battery power; Apple have been very clever when it comes to power consumption. It's impressive.

I took a review concerning this topic:
http://www.phonearena.com/news/LG-O...-Galaxy-S-III-claims-an-LG-experiment_id35585
LG Optimus also has 2100mAh (I know, doesn't have to be same manufacteur) and the same components and it has a really good battery life.
Always better than S3.
+ LG says that their battery has more charging cycles. In the data sheet of Nexus 4 and Optimus G it says 800 instead of the usual 500:

Nice!
2100mAh should be pretty good, especially without LTE.

One other small thing to note, the battery is a bit higher voltage than your standard cell. 3.8v vs 3.6v, so that works out to 7.98Wh vs 7.56Wh.

Mine was giving me about 36 hrs with moderate use on ARHD ? Like a year ago ? Besides this phone will have so many kernels and rooms to choose from in like a month or so that will help you get better management of it that I just don't see it being an issue ??? And chances are you might not even have it after two years when the battery starts degrading ...
I'm considering buying Nexus 4 and after reading various reviews and user opinions my only concern is - how is the battery life?
Some are saying it's great, others are saying it's crap... See me confused.
I've got no intention of using it for watching movies or heavy gaming, but would still like it to last me at least whole day without charging (24 hrs).
Currently, my SGS2 lasts from 1,5-2 days without charging (I'm using JuiceDefender).
Can anyone comment on the subject, especially compared to SGS2?
I had a galaxy s2 before the nexus. Compared to my s2 the nexus pisses through power mainly on WiFi and surfing the web. Location services and google now use battery a lot too + overnight i loose more power compared to thr s2. I'm hoping its software related and Google improve battery in updates to JB.
I don't believe those who say the battery is great for one minute.
Pretty damn good so far for me my SGS2 would be dead in half the time, even with the screen off!

Depending on the apps you use, battery drain can be a huge downer for this phone. I use eBuddies for aim chats at work and that thing drains through, so does GChat. Navigation apps such as Google Maps or Navigon also burn battery like there's no tomorrow.
So the question of battery life really is dependent on your daily needs. The difference with other phones is that some have removable batteries.
Expect to invest in a mobile recharger, or to have spare charge cables always on hand with this phone.
I don't do much with my N4 during the day and came over from an SGS2. SGS2 by far outperforms the N4 on battery life from my experiences.
It seems the N4 has fantastic idle battery drain. I let it sit a full 7 hours over night and lost 3% battery, but it seems when you're actually using the phone, the battery is middle of the road. I'd say its still better than my S2 and as good, or slightly better than my S3. :good:

Since i always post the same problem, battery life could be better, will probably get 8-9 hours, with 3-4 screen time. Gonna keep it stock kernal so its more stable.

It's 2600 mAh, not 2800 mAh. And why do you think it won't be enough? They're probably making AMOLED even more efficient than it was last year and the new Exynos SoC is up to 30% more efficient than current offers because of the 14 nm half node.
They are slapping power user in the face with non removable battery. Now instead of carrying spare battery I need to bring a chunky PowerBank. Can't Samsung realize they are not apple and they abandon their core audience do them no good?

is it not possible to insert 3000 mAh battery to s6? it won't be more usefull for users? why samsung still parsimonious? s5 has 2800 mAh battery & s4 has 2600 mAh battery and s6 will come with 2600 mAh battery. sometimes i can't understand to Samsung.

Like I said, if these rumors get confirmed, it's quite possible that the GS6 will perform better than current smartphones, even with a smaller battery. Which in that case allows a slimmer, lighter device.
Enviado do meu Galaxy S5
If the phone is getting a QHD Screen I doubt that there will be any better battery results than the other mainstream smartphones.
Just compare the Note 3 vs Note 4.
What about a poll with:
a) I want a phone slim like a post card with 3-5 hours SOT
b) I want a phone slim like a S3/One/Lumia with 12-15 hours SOT

The QHD on the Korean S5 LTE-A had about the same battery life as the US variant. Therefore, the QHD on the S6 should have the same...if not better battery life even with a smaller 2600 battery. I wouldn't worry too much about...my only complaint is that it'll be non-removable

Since S6 was said to use Exynos7420 instead of Qualcomm........the consumption of cortex A57 would exceed A15 and Krait a lot according to Anandtech

I'll take Option C. A phone that is 12mm thin and has more like 20 hours of SOT.
There's no point in making super powerful smartphones, if we can't use them like the pocket sized PCs that they have evolved into. I'm sure there are many people who would love to use their phone to get actual work done without having to worry about the battery. Also, since batteries wear out over time, I'd rather have a bigger battery than what would seem to be big enough at first.

Because the CPU/GPU only within the same generation range on 1080P(note3) and 2K(note4) though on paper spec. the latter one should be a lot better but still same generation and indeed that kind of power isn't enough to push 2K. Hence, the CPU/GPU will always require to run at a higher clock and battery draining even just on 2D.
S6 is running a whole new CPU with 14nm manufacturing process, the situation should be much better though but I agreed 1080P is enough on a tiny screen and I also prefer more battery life.
Is the battery removable?
I don't think so
The battery will NOT be 2600 for the MILLIONTH TIME. IT'S ANNOYING ME HOW blind all these websites and you lot are. The info is right in front of you the batteries were for G925 WHICH IS THE CODE FOR THE S EDGE. NOT S6
SO WHAT DOES THAT MEAN? S6 WILL BE MORE JUST LIKE WITH THE NOTE
NOTE 4 BATTERY 3220
NOTE EDGE BATTERY 3000
NOW STOP SAYING IT'LL BE 2600.
Its funny to see how rumors, leaks and teasers mess with people's brains and expectations, the media really knows how to get in your heads. We will know by sunday's time, then all of you will really have something solid to criticize until the next device comes up, so just hang in there. I just hope it lasts me the whole day on moderate use, so that I can charge it overnight
Butthurt much?
Battery size difference of 200 mah is meaningless. What matters is actual battery performance. Is there a correlation? Sure. Does every phone last same length of time with the same capacity battery? Hell, no.
