Seriously? I'm getting eye strain if I was using the SGS2 on 100% brightness all day :p

Auto brightness provided perfect readability in pretty much any situation I found myself up to date. Really no complaints there.

However, I agree with it not being good for the phone to discharge so fast/charge so slow. I have seen that on some snapdragon phones too however ... So no biggie imo.
[Galaxy S II General] blackheart2925:
Interesting...but cmon why would you want a screen at 100% brightness? That's too bright and hurts the eyes...except when you are in direct sunlight rest of the time I put all my devices at 20% or less...I have also driven long distance along with my HD2 for navigation and my observation is that discharge and charge happens almost equally when running gps...but over a period of charging does happen...using a higher capacity charger should charge the phone faster but of course will generate more heat...

And I think phones around the 4.5" size are great...more viewing real estate when surfing or watching bids...and I don't mind the two hand usage :-)
[Galaxy S II General] obeyerik:
I didn't read every single post but here's my take anyways

I switched over from a iphone 4. I had a rooted droid incredible w cyanogen but moved to Europe where I can't use it and didn't like any of the android phones that were available at the time. This week I bought the Galaxy S II to finally get off the iphone and back to android and my battery life is great.

I use the phone pretty regularly, checking emails, checking the internet, whats app, text messaging, reading ebooks, and of course talking on the phone

I unplugged the phone 20h 43m 51s ago and still have 70% battery. I am using juice defender and I have a job where I have to work and not play with my phone constantly but I fell asleep reading a book in Aldiko, was using it this morning before work for a while, at each break, text messaging through out the day and playing games for a little while.

I don't know what more you could want from a battery. Everyone wants the phone to replace their laptop or netbook, but is baffled/ angry when the battery doesnt hold up. My work colleague has a net book and the battery only goes for 4 hours. If I use my phone like a netbook the battery lasts longer than that, and I find that impressive. Of course if battery length was my main criteria I would get a blackberry or a cheap nokia, but then I couldnt be playing angry birds and all that stuff. When you think about what cell phones were like 20 years ago, having a device in your pocket that you can do almost EVERYTHING on is pretty amazing.

Some of the whining on these sites is really ridiculous and I almost have to wonder if its sarcastic- "My phone sucks cause I can't watch HD movies on it all day, while sending picture messages and surfing the web, all the while receiving emails and chats instantly from all over the world" boo hoo are you people serious?
[Galaxy S II General] Mittaa:
Thanks ... completely agree :-)

On a travel I used my phone from early morning to evening with heavy use of GPS, camera, video editing and some WiFi ... still 30% left in late evening.

Normal daily usage with 2 hours of news reading, 1½ hour of talking and text'ing my battery last more than 2 days ...

In a week-ends me and my phone take a break, only ½ hour daily talk and text, so it's mainly on standby and therefore lasting 4~5 days

It have been totally stable, accurate GPS, no root, no tweak, no freezing, just plain stock ...

I think it's fantastic and I'm very satisfied with my SGS2.
[Galaxy S II General] JuniorGG:
Well, you are VERY lucky!

My phone struggles to last 1 day, and just the display at normal brightness eats out 30% of my battery per hour.

As you can see we are of different opinion. I mean, I don't think that you lie, but me neither... therefore there must be something odd with this phones or heir batteries, don't you think???
[Galaxy S II General] urbanomad:
I just updated to WKE7 from WKE2 today. I have noticed an increase in speed and I think the battery isn't draining in less than a day with little use.
[Galaxy S II General] stoney73:
+1

only difference is that I have rooted my phone, and 'frozen' a lot of the bloatware. apart from that, I'm on KE7.

I did find that after initially updating to KE7 through kies the phone suffered from

higher battery drain. At which point I wiped the cache/dalvik/factory reset(after backing up my apps) and reinstalled KE7 via Odin.

Since then, with light to medium use I'm getting 24+ hours from it. I did the same for my partners phone(sgs2) and she is still on 50-60% after coming home from work.
[Galaxy S II General] Mittaa:
I think it depend a lot how you use your phone. I'm not a heavy user. I do not have any automatic updates running and no twitter, no Face book and no living wallpaper running in background.

It's only using battery when I actually use the phone (and of course ½~1% per hour in standby).

Having been in my garden most of the day, my actual status now is 20 hours on battery going from 93% to 81%. I have had a few phone calls and 10 minutes on market updating some apps. So today VERY light usage.

One thing I noticed is the screen brightness having a very big impact on battery time. If I play a game or watch a movie with 100% brightness ... I too can drain battery after 5~6 hours.
[Galaxy S II General] Endr1:
This is my 4th day with my sgs2. I waited the usual 3 total recharge to have a relible idea of the battery.

Last phones were DHD e ip4. The Dhd suffered from a really small battery, sense bloatware and it was hard to get more than 8 hrs of regular use. (mean 5sms/im, 1 mail, twitter, 10 min music for every hour). The ip4 lasted longer but it never kept all the notification together and I hate that little cramped screen. Don't know about retina but for me it is just small.

Anyway my xp with this sgs2 are easy to summerize:

0.9% per hour in sleep mode with 3g. (still getting twitter and mail odd course)

10% per hour under intense use outdoor with the sun, 6% indoor.

I have note rooted yet, blocking stupid bloatware and services like wifi sharing and samsung ****ty hubs is really improving battery life?

OT: what is the point of a custom recovery if i can flash cooked rom via odin? Am I loosing something here? Thx
[Galaxy S II General] ph00ny:
I learned this from using captivate but on samsung phones with amoled screen, simple things such as using darker background/theme can do wonders with battery life. That's the first thing i did with the damn phone. i changed the background to plain black until recently
[Galaxy S II General] le3ky:
A battery monitor im using says my average is 16 hours, and thats fairly heavy use! Quite happy with this battery tbh.
[Galaxy S II General] urbanomad:
I agree... my battery dies in less than one day with syncing off, Wifi off, Data Network Mode off, etc. It also takes about 4-6 hours to charge completely. If I charge it completely, and let it "sleep" all night with 1 alarm set, battery is diminished about 15%, if I listen to music for about 30 minutes then let it sleep again for about 3-4 hours time. The batter is then reduced by about 70%.
[Galaxy S II General] ithehappy:
The Battery back up is OKAY imo, it went down to 30% from 70% after surfing net for 3 straight hours using Wi-Fi connection. So I guess it's ok, still could have been better. One great thing for me is if you forget to turn the Wi-Fi off the device doesn't drain that much battery which was supposedly the biggest problem I had on S8500. Anyway I am gonna install Juice Defender and see how it helps on battery back up, heard that it does very well, yet to prove it.
[Galaxy S II General] zkyevolved:
Here's my usage after 1 day, my first day, and first charge. I charged it to 100% then let it go the rest of the day. Auto screen brightness, 3G + wifi, but at work for 3 hours I didn't get 3G (so I got EDGE).

Not bad for the first charge :)
[Galaxy S II General] mancuk29:
how did you get rid of the tektrak ??? i cant work out how to get rid of it .... pls help
[Galaxy S II General] redmok:
The battery is doing OK so far. I use my phone a lot. Screen is on 4 - 5 hours a day, I download a lot of apps, 1 hour of voice calls and around 1 hour of skype calls. The battery will last around 13 hours before I need to recharge unless some a weird bug appears, I suspect skype, where the phone is awake all the time. I would still like my battery to last for something like 18 hours. I guess when I get used to the phone and stop playing with it every 30 sec.
[Galaxy S II General] :
compared to the SGSI the battery life on SGSII sucks. there might be a lot of reasons and bugs for this.

currently i would not buy the SGSII again. this might be a killer phone but at the moment it only kills your battery. so it's useless.
[Galaxy S II General] lovidore:
I just came from a Blackberry 9700. The battery life on that is really good.

Now that I have a SGSII I developed this insane paranoia that if the phone somehow reaches 60% all hell will break loose and the heavens will come crashing to the ground. And now I feel obliged to carry a USB cable with me everywhere I go and keep my phone charged whenever I have the chance.

One way to combat this however is juice defender (a bunch of people have mentioned this before) It's a really nifty little app and helps turn off Data/wifi/syncing etc when you need them automatically. I suggest you try that.
[Galaxy S II General] Riqz:
Are you crazy? Sgs2 has the best battery life I've seen on any smartphone. All it needs is a bit of tinkering to remove bloatware apps

. It easily lasts two days or more for me

[General Questions and Answers] Lennart5:
Hiya guys and girls!

Very often, my SGS won't play any media anymore. If i press play on my meridian widget, it skips through all the songs in the selected album and then gives an error which says something like can't play this media. After rebooting it starts working again. I suspect it has got something to do with my (standard) earplugs, because it doesn't seem to happen when i don't use the earplugs. I'm running Darky's Rom, but had the problem with Froyo as well. Not as often however, but maybe that's just me :).

Does anyone know a solution or cause for this? It's pretty frustrating.

Thanks in advance!

[General Questions and Answers] Serious_Beans:
Well I've got about $450 that I'm going to use to buy a G2x (probably for a lot cheaper since they are going for $350-$400 locally) BUT I'm wondering if it's worth buying it now seeing as the Sensation is coming out June 8th. I'm guessing it will be $500 off contract as usual so should I save my money, buy some last gen phone and wait for the Sensation or should I buy the G2x and hope the price doesn't fall too low by next month and try to sell it?
[General Questions and Answers] deez1234:
I would go with the G2X if your looking for more development. The Sensation is supposed to be pretty locked down.
[General Questions and Answers] donharden2002:
I think the sensation will be the better phone out of the box but like was said, it will be locked down so probably won't have much dev support.
[General Questions and Answers] Serious_Beans:
Hmm, well other phones have had locked boot loaders and had decent support no? If not then yeah I guess I'll stick with the G2x, I prefer development over out of the box performance.
[General Questions and Answers] cordaylec:
Yea I was wondering the samething. Might get both one for me and the other for the wife. Hope the Sensation is easy to MOD since I'll be coming from the HD2.
[General Questions and Answers] Serious_Beans:
It won't be nearly as open as the HD2 and as far as modding I'm sure it'd be easier but it will probably take a while for devs to figure out how to unlock the bootloader.
[General Questions and Answers] crawler9:
I am sending my G2x back. It just doesn't seem that impressive. It doesn't feel like as big of a leap forward as I was hoping. I might get the Sensation.
[General Questions and Answers] Serious_Beans:
A big leap coming from which device?

It's just the first Tegra 2 phone that's why. It's not THAT impressive, but the UI speed is noticeably faster.
[General Questions and Answers] Step666:
Assuming they do at all.
[General Questions and Answers] Serious_Beans:
Yeah :/ I hope they do because it's a really nice device, design and specs, but the SGS2 looks pretty sick, and with quadrant scores of 3500, that's impressive and it's already been OC'd to 1.5ghz. Quadrant scores don't matter really much, and I don't really like the way it looks, I prefer the design of the Sensation so I really do hope that someone figures out a way to unlock the bootloader and if not I'm sticking with the G2x.
[General Questions and Answers] Step666:
The Galaxy S2's specs are better IMO - the CPU seems to be more capable, it has more RAM and the slight increase in screen res doesn't really make up for the difference between S-LCD and S-AMOLED+.

Not to mention it's so light...
[General Questions and Answers] ErOR22:
@OP: What device you have now? I personally wouldn't recommend upgrading right now, wait until end of the year at least. Mobile technology is in that stage right now where a 6 month old phone is "outdated".

And I would definitely wait for Sensation to see how things go down and see if bootloader is encrypted and then maybe make your decision.

That's subjective.

Yep +1

Sure it does! Just look at the difference between 2 30" monitors, one running at 1920x1080 and other at 2560x1600, the difference is HUGE. Plus I would take close to accurate colors over somewhat saturated colors any day.

That's a down point for many people including me, I need to feel some weight to a phone. Also Galaxy is made out of plastic which also is a thumbs down from me.
[General Questions and Answers] Step666:
Not really.

It's posted some ridiculous benchmarks, which it's true mean very little individually but when you take them all together, it speaks volumes.

Now you're just being ridiculous.

It's more like the difference between 1920x1200 and 1920x1080.

qHD is half-arsed BS, it's an excuse for manufacturers to avoid actually improving screen resolutions in a meaningful way.

But not necessarily for the OP.
[General Questions and Answers] 1milenia:
g2x quadrant test blows any phone of the planet with its dual core processor
[General Questions and Answers] ErOR22:
Well from what I have seen I wasn't THAT impressed. It's better for sure but for how much these things cost I'm not sure it's worth it.

I knew you were gonna say that and well after thinking about it for a bit I must say I was being a bit ridiculous.

But unless there are more powerful GPUs in phones they can't really up the resolution that much. Look at the ASUS Transformer tablet (I think that's the name), quite a bit of lag.

Of course but I was just stating my opinion and fact in case OP wasn't aware of that.

Anyway I think either phone is great it's just a matter of preference and it's ability to be unlocked and flashed.

EDIT: My DHD at stock speed achieves around 2300 Quadrant and 37fps in NenaMark. At 1.6Ghz Quadrant scores around 3300 and NenaMark is around 46fps. Going higher didn't do much difference as the device is majorly undervolted.

Is the extra cost really worth the extra performance?
[General Questions and Answers] Step666:
It generally out-does the Tegra2-based handsets by about 20% if memory serves (which makes sense since they're both built around the same ARM architecture and the Exynos CPU in the Galaxy S2 is clocked 20% faster) but like all these things, you get the odd benchmark that seems to go against the flow as it were.

On the other hand, the benchmarks for the 1.5GHz MSM8660 dev hardware weren't generally 50% better than than the Tegra2 benchmarks, which leaves me thinking that down-clocked to 1.2GHz like the Sensation and Evo 3D will use, it won't be able to compete with the Exynos.

Of course, these are all synthetic benchmarks and not indicative of real-world performance but combined with the higher screen resolution and less RAM, I have a suspicion the Sensation won't feel as smooth or as quick as the Galaxy S2.

Well, if they were to push higher screen resolutions, manufacturers could always use something like the SGX543 GPU the iPad2 uses - it's supposed to be an improved version of the SGX540 the original Galaxy S uses, which is still one of the best GPUs in use in mobile phones just now.

As for the Transformer, I'm a bit surprised - I thought the reviews were generally very positive, much more so than those of the Xoom and the new Acer tablet.

edit:

I can't speak for New Zealand but over here the SIM-free and contract prices for the Galaxy S2 are the same as they were for the Desire HD when it was first launched.

Obviously it's come down in price since then but so will the Samsung in time.
[General Questions and Answers] Serious_Beans:
I personally dislike the light feeling of the Galaxy S series. The only one that wasn't so bad was the Nexus S, it had a decent weight to it, but I prefer heavier phones. Also I really love SAMOLED Technology, and I heard SAMOLED+ is even better.

As far as benchmarks and speed, if the UI is smooth after a certain point you can't really tell if it's any smoother.

Also if the G2x has better development that means overclocking and improved kernels and roms which would make it better than the Sensation. I really like the specs of the SGS2 but if it's as light as the Vibrant I will hate it. Currently I'm using no phone lol and I don't feel justified paying $250 for a Nexus One or $375 for a Nexus S when I can get a G2x locally for $350 which is what I'm going to pick it up for tomorrow. I'm really hoping after this leap in phone processing power they will focus on battery and screen resolution. Every screen should be SAMOLED+ and Retina Display with a weeks worth of battery. I'm sure the technology for it exists already...hell they could use tiny fuel cells to power everything, but most big battery companies have patented that technology so fail there.
[General Questions and Answers] tooter1:
I know it doesn't mean that much but, I just ran my first quadrant score and it was 2725 on the G2x I got today.

I'm really liking this phone! I have to order some kind of protection for it now.
[General Questions and Answers] Serious_Beans:
That's pretty high! I'm hoping to keep my next phone for AT LEAST 6 months. The last phone I had was my LE Nexus S(which got scammed :/ ) which I had for about 4 months? Maybe a little less, but if the only phones I have to look forward to are the Sensation and SGS2 I might just keep the G2x. Will have to see how the SGS2 feels in hand.
[General Questions and Answers] jwalk74:
I got a 3200 quadrant on my Vibrant, overclocked at 1.42!
[General Questions and Answers] ErOR22:
It's a great tablet, it's just has noticeable input lag due to not enough graphics power. I'm only basing this of videos I've seen and reviews.

Which was hugely overpriced when it was released. In a matter of 4 months it's come down around $400NZD, another thing is everything here is much more expensive then USA.

$350 for G2x!! Is that on a contract because that is damn cheap.

And about the lightness I feel the same way, 2nd reason why I didn't buy SGS and got a DHD. Also it seems like Sensation will be of the same build type I can imagine it will feel great in the hand just as a DHD feels.

I can see once these dual core phones achieve close to 2Ghz they are gonna be pretty dam fast, and chew battery like crazy.

Nope, someone is just selling them for $350 lol. The guy has 5 of them!
[General Questions and Answers] nok3:
I like the htc sensation more.. it better than the g2x.. but it's really difficult to install custom roms on the HTC, because they have locked some things.
[General Questions and Answers] Serious_Beans:
Depends what you mean by better.

The fact that the bootloader is locked and that it isn't running stock makes me dislike it...so I can't really say it's better. Maybe hardware wise, but then also it only has 1gb internal while the G2x has 8gb and allows for about 6gb of storage so that's an added 6gb on top of the 16gb I have which is really useful since I have a crap load of music.

I've decided to just stick with the G2x. It's beast enough of a phone and should last me for at least 6 months until something nicer comes out or the Sensation has more development.

[Galaxy S II General] El Salvador:
When I look at my battery usage I saw that my S2 is constantly awake, even when I turn the screen off and put the phone away for a couple of hours.

I've turned off Wifi/3G and even background sync, but it stays awake all the time causing the battery to drain a lot faster than I want. Is there a way to stop this?

I hear people talking about theirs dropping only a couple percent per hour when not using the phone but mine at least drains 10% per hour.

Could it be the Social Hub?

Btw, my S2 runs on the latest KE2 firmware.
[Galaxy S II General] LarcusMywood:
For me, I've noticed a big decrease in idle-battery draining when I rooted and removed Social Hub and I never even used it. It still stays "awake" as much as it did before on the little lines in the battery usage app, but a lot more juice. :)

Used to lose 10% per hour like you, now more like 5%.
