[Galaxy S II General] Zakir.Umar:
I've finally got rid of my SGS2.

It is an amazing phone, too many great features to list, but all these features are useless when the battery life is ridiculous.

I tried everything, i rooted and froze all the preloaded apps, still didn't work.

I flashed Litening custom ROM, still made no difference.

I also tried KE2 and KE7, still it made no difference.

Oh, and i calibrated my battery again and again, but still the battery life was a load of crap.

I also purchased Juice Defender Pro, and lo and behold, still no difference.

I noticed that leaving it idle kept the battery alive, but as the cnet Australia article exactly points out, when i actually used it to surf the web it drained at a ridiculous level.

I realised this is all bull**** and that i didn't pay for a £400+ phone to go through all this crap of flashing ROMs and rooting my device just because of the ridiculous battery life which did not even last me a day. I wasn't asking for much, just from morning till night; but no, SGS2 did not offer me that.

I am not a heavy user either, i would say moderate at most. I understand if i turned off data and wifi and only switched on when i needed and turned off sync it would have helped, but like i said; i realised this is all bull**** and i didn't pay £400+ to have to do that when i know my friends don't have to do that on theirs.

I am not sure now, whether it is Samsung or Android? I want a new smartphone, certainly not SGS2, but it feels i have to go for iPhone because all this battery stuff makes me mad.

I don't know why some people have great battery life on theirs...but certainly there is a problem here because a significant number of people do have some serious issues.
[Galaxy S II General] nikzDHD:
Very odd, I've always got data on, apps syncing and such and my battery life is really good.

Good luck with your next phone, which phone will you be getting?
[Galaxy S II General] zkyevolved:
That's strange. I've been using mine all day :s Not HEAVY usage, but nevertheless, ALL day usage (tweeting, emails, whatsapp, browsing, downloading apps, etc) and I still have 35% left :s

If I may state the obvious, maybe you got a dud battery :s.

Anyways, try the Sensation! That's the next great phone :) But I doubt battery life will be BETTER. If anything, it'll be on par or worse. HTC makes good phones, but those bad boys suck battery like a baby from a mama's teet.
[Galaxy S II General] Noam23:
I don't understand why browsing the web should consume so much battery. I mean, when the page has finished loading and you're reading, it's mainly the screen that should take battery, and the screen suppose to be very energy efficient (OLED).
[Galaxy S II General] zkyevolved:
Yes, but most websites are WHITE. So that consumes 3x the amount of battery as an LCD.

Also, the GPU kicks in if you're using the stock browser. You can get an extra half our or 1 hour if you're good about it using Opera Mobile, which doesn't use hardware acceleration.
[Galaxy S II General] Noam23:
If by saving a few seconds of page loading time, the GPU is wasting a few *hours* of battery time, then I'd say that's a pretty lousy tradeoff (one that shouldn't have been made in the first place).
[Galaxy S II General] zkyevolved:
Agreed. I prefer opera mobile anyways.
[Galaxy S II General] Zakir.Umar:
I'm quite confused now! I thought the S2 was supposed to be the best android out there at the mo?

I'm an Android person all the way, but i feel Android just hasn't got things perfect yet.

I don't know, maybe? It never used to run out in my pocket, but exactly how the cnet article describes when used it ran out at a significantly fast rate. There must be an issue with the battery with certain handsets, not all, because i have Googled this and it seems to be a very hot topic. It can't just be all coincidence. Although we have the same phones, perhaps there are slight variations in different handsets from different parts of the world and different manufacturing dates which may explain why some people have good battery?
[Galaxy S II General] lynxboy:
Really enjoyed the NordicHardware and Swedroid atricles and recommend them to anyone who hasn't had a look!

Regards.
[Galaxy S II General] lgkahn:
i have to agree with them.. with no use i only get 1 day max out of sgs ii.. with use.. probably about 12 hours.

with my sgs i get 2.5 to 3 days with use.

battery life sucks on my sgs ii.. hopefully the 2.3.4 upcoming release will fix it.

but just found out on the sgs forums that the 2.3.4 releaase has not fixed the pptp vpn over 3g issue.. bummer.
[Galaxy S II General] RogerPodacter:
In my never ending battery testing, I recently came across some iPhone 4 power data and it shows that the iPhone 4 with screen on but not doing anything pulls 75 mA. Now my nexus one on minimum brightness, showing a complete full screen of pure black color pulls 105 mA no matter how much I try to get it lower. On full brightness its up to 250 and 350 mA. I can get it up to pulling 750 mA loading a white web site.

So it baffles me how apple got their power so low. But other measurements do show the iPhone 4 pulling 600 mA during navigation, so that does line up with android equivalents. Maybe lithium polymer is just more robust over lithium ion.
[Galaxy S II General] leedavis:
Exactly. Not great! I do hope they fix it soon. Fed up of my wife taking the p*ss because her iPhone 4 lasts 2 full days with usage heavier than mine. :(
[Galaxy S II General] android53:
Got a link?
[Galaxy S II General] bilboa1:
The review is b/s. These guys even report the drop from 100% to 90% or less as an issue, because they DONT KNOW HOW IT WORKS. Which is typical of such news websites, a shame, and horribly wrong.

For the record, the 100% displayed by the phone is fake, because the battery is not charged constantly, as it would kill it quickly over time. Usually when you unplug the phone its charged between 90 and 100% (-or 95 and 100-) but displays 100% and will "appear to drain faster" from 100 to 90 or less of course.

Such IGNORANCE is so annoying.

On a side note, the SGS2 does drain more than the IP4 with screen on (the screen is much larger anyway), but it seems to drain a lot less on standby (granted proper settings / apps installed).

For the record i bough an IP4 and I still own it. Also a SGS, 2x3G and 1x3GS.

The SGS was arguably as good or better than the IP4 for some things, worse for other things (battery life is pretty bad on the SGS). The SGS2 kill them both on all points I can think of except audio quality.
[Galaxy S II General] zkyevolved:
My iPhone 4 doesn't last days. She must have some magic fingers. LOL. On 3g mu i4 never lasted more than 6 hours (total. Not on screen time) and I'm a heavy user. I've had two different iPhones as well. So I don't think I had two duds. Standby time is good. But my % drops every minute. 30 min on my i4 with 3g and listening to stored music will kill 15% of my battery.
[Galaxy S II General] Cetin:
Same usage iph4 (im+ messenger,sip client standby on wlan all the time,no games, webbrowser a little,...) since 1 year my iph4 lasts one and a half day and with lot of more usage like internetradio etc. too.

My SGS2 lasts just maximum 12 hours even without any webbrowser.

Yesterday i navigated 1 hour with navigon software and battery lost 50%. my iph4 just 5%.

Yesterday i went bed at 2am with 32% left and i wanted just to look on the clock at 9 am but the sgs2 was down. Unbelievable! Who knows when it went off the night.

So no one can tell me that sgs2 is tied with iph4 in battery drain.

Sgs2 is completely useless in that case!

Best smartphone with bad battery software management. Hope it is not hardware related.
[Galaxy S II General] RogerPodacter:
That's strange cause I've done browsing tests on the iPhone 4 by browsing 30 minutes and the percentage went down very slow, 1% every 7-10 minutes. Interesting.
[Galaxy S II General] RogerPodacter:
Its still only anecdotal evidence but searching Google images for the term "iphone bootvoltage" with no spaces brings up the only few screen shots I could get. Only 4 image results came up, each showing shots of current of 70 mA, 74 mA, 71 mA. Anecdotal, yes, but in line with my findings from actual use; my search continues.

Then search "iPhone batterydetective" has info where I browsed this thread:

http://myapple.pl/iphone-ipod-touch/165417-bateria-w-iphone-zuzycie-uzycie-sprawdz-i-swoja-7.html

Those show higher mA values doing more intensive tasks which does line up with the high android mA numbers, so those seem to make sense.
[Galaxy S II General] bilboa1:
one big diff on the iphones is that its hard to shoot yourself in the phone regarding battery management.

on android is hard NOT to shoot yourself in the foot regarding that

it's probably what's causing most troubles. sgs2 standby with 3 emails checks on push and a couple of other things every 1 or 2h should barely take a %

however, some apps wake up the phone a lot more than they need to, or not the way they should, and those can really drain battery quickly even on standby. *cough* skype *cough* tango etc (actually only im+ and gtalk seems to work with push half properly - those barely use any battery)
[Galaxy S II General] android53:
+1 I have tested the iphone 4 myself and agree.

Unless you have really bad signal you get no worse than 1% drain per 5min

I managed 11 hours browsing on wifi lol
[Galaxy S II General] RogerPodacter:
Well I feel a bit better. Today I did extensive test. I lined up iPhone 4 next to nexus one, and literally browsed the web simultaneously. Click each link together, scroll and read simultaneously, then load the next thread. Did an hour straight literally, and the iPhone 4 wasn't that much different. It lost 20% in that hour. My n1 a bit more but it was close. So the iPhone wasn't all that much better than I thought.

So the galaxy s2 likely is similarly near performance. My flaw last test was leaving wifi on during my test, but using 3g on the other phone.
[Galaxy S II General] ph00ny:
I left my sgsii and carried around my bb once and this is what i got on my sgs ii

Don't forget. Music players will use different amounts of power based on the volume level too.
[Galaxy S II General] android53:
was this test using 3g or wifi?

3g drain is only slightly better than on android

Wifi drain is massively better
[Galaxy S II General] RogerPodacter:
this was purposely on 3G because wifi browsing gives incredibly better battery life. that was the problem with one of my earlier tests, the iphone was on wifi and the n1 was on 3G. 3g browsing eats battery like nobody's business. so with both on 3G, it was very close to equal, with the iphone only being slightly better.

it wasnt a blowout like before.
[Galaxy S II General] ShaggyDragon:
I get terrible battery life on my SGS - I mean, what sort of smart phone only lasts 2 days 14 hours and has 18% left??

See screen capture.
[Galaxy S II General] huzz:
LMAO good one :-p
[Galaxy S II General] android53:
Now post the screen on time
[Galaxy S II General] bcam117:
Cnet is full of ****. I don't know how some of these idiots end up with these jobs.
[Galaxy S II General] dlo2008:
That was a looong read to learn nothing at all about SGS2 battery life... Post #72 was by far the best.

- battery life from 6h-52h?

- iphone 4 sucks/great

- big AMOLED screens seem not to be so power efficient?

I get about 20hrs of 'normal usage' (calling, GPS, a bit of wifi-browsing), so I'm quite content. Maybe 'usage' should be defined somewhere properly, or is it?

I am convinced that my battery life will get even better when I start to get sick of playing with the phone (I cannot stop installing apps and flipping screens, how can I judge battery life?). And for longer term, I think I'll buy one of these: http://cgi.ebay.co.uk/4000mAh-Solar-Charger-Samsung-Galaxy-S2-i9100-/130534279639

By the way, didn't really like the CNET review either...

Hi,

I have a Samsung GT500 (i5500) and i unofficially upgraded to 2.2. I am now wanting to change my device ID but i seem to have to Root my phone first?

Is it possible to Root with it being 2.2, or will i have to Downgrade and then root?

If there is a way to change Device ID without rooting, that would be better

Thanks Guys
[Atrix 4G Q&A, Help & Troubleshooting] winky!:
Hi,

I recently moved from the US (AT&T) to Australia (and now use Telstra). I got my phone working... all except my data. I have absolutely no data. When I first unlocked my phone, I recieved emails, but now, nothing.

I checked my APN and entered in all of Telstra's info, and still, nothing.

What caused this? How do I fix it? I have been reading of people swapping radios without changing their SBF.. How do you do that? Is the process hard? lay it all out for me.
[Atrix 4G Q&A, Help & Troubleshooting] SC.:
My AT&T Atrix is working on Telstra. Use http://configure.telstra.com.au/ it will provision the correct APN values for you automagically. That should fix it :)

Hey guys,

I recently installed CM7 nightly #22 andere noticed a strange problem with the UKW Radio: If I try to play the radio trough my headphones it stops after a few seconds after the Softkey Backlight goes off. If I keep clicking on the softkeys the radio works. Ans ideas how to fix this?

I know that this are problems of a nightly but maybe someone know how to fix this.

Thought some of you might want to see some custom boot animations(like on TRIGGER)!!!

This is the KB5 kernel that Krylon360 modded to allow bootanimation.zip... I just made it cwm flashable. should work flashed over any rom. :-)

Instructions:

Delete the bootsamsung.qmg & bootsamsungloop.qmg files from /system/media

Push a custom bootanimation.zip to /system/media

Delete the PowerOn.wav file from /system/etc

Quickboot to recovery

Flash KB5CUSTOMKERNEL.ZIP

Reboot!

Thanks again to krylon360, Dr. honk, Supercurio and Rickyc19!

NOTE:

IF FLASHING OVER A ROM THAT ALREADY HAS A CUSTOM BOOT ANIMATION (LIKE TRIGGER) JUST FLASH KERNEL AND REBOOT.
[Samsung Galaxy S (4G Model)] rickyc19:
thank you kind sir i will test it and report back with you

ok so just so people dont get confused...i think you are supposed to delete bootsamsung.qmg because there is no samsungboot.qmg ;) just thought i'd let ya know :)

also there is another file called bootsamsungloop.qmg do we delete that?

haha i was about to ask you if you could do something like that :D

thank you soo much!!! :D
[Samsung Galaxy S (4G Model)] rickyc19:
nope they are 2 different kernels which will override each other...sorry bud for now its 1 or the other ;)
[Samsung Galaxy S (4G Model)] robbbbit:
You're right... One kernel at a time...

Yes u can use this kernel with the kd1 rom. This can be flashed over ANY ROM. :-)
[Samsung Galaxy S (4G Model)] rickyc19:
oh yeah...i thought he meant like flashing over the bali kernel sorry :(
[Samsung Galaxy S (4G Model)] mad_fitter:
Ya, at this stage, if you flash a new kernel....it overwrites the one your using now. @robbbbit will have to implement these changes to each kernel individually. The only way I know of to overwrite a kernel is if its essentially the same kernel with minor changes. It's impossible (from what I know) to take parts of one and add to another...without building it from source.

sent from the pits of hell (from an sgs4g)
[Samsung Galaxy S (4G Model)] robbbbit:
Yeah... Can't exhange parts. Just tweakage. Lol, i cant believe im even using this instead of bali(no uv). i just love bootanimations... Har.

Hee hee hee. I feel ya. I dislike the t-mo jingle with a passion, lol.

[Samsung Galaxy S (4G Model)] fknfocused:
I know that we now have two custom roms now, but i think it would be good to have the options just like the modems. I cant believe were finally getting there! im so excited!!

how can i open the kernel to modify/compare? Id like to try and help.
[Samsung Galaxy S (4G Model)] mad_fitter:
Would have to do it from source I believe. Decompile to make changes, or compile from scratch. I don't know of any other way to make kernel changes.
[Samsung Galaxy S (4G Model)] dsexton702:

[Epic 4G General] Pete720:
Hello all. I am sort of new to the smartphone hacking (for lack of a better word). I recently switched from my Evo 4G to the Epic 4G. Evo was great but I just loved the AMOLED screen too much and the slide out keyboard. Actually my personal opinion is the Epic is a better phone, again personal haha. But the Epic does need tweaking. I do experience more issues with it than I did with the Evo. I have spent days on this forum reading about Odin and ROMS and what not and I am thinking of taking Syndicate Frozen for a test drive. I REALLY want Gingerbread as I gave my Evo to my wife and I did the 2.3 update and that Evo phone is SO much better. Anyway since no one really knows when the Epic is getting the new cookie rom I want to try something else in the meantime. A couple questions I have is: oh and I am waiting for 1.1.1 Fully loaded I like touchwiz

What exactly is removed from the phone ie. The "bloat"

Will I still be able to put Gingerbread on my phone when it releases?

What exact files and programs do I need to have on my computer to get Frozen?

How do I backup my phone so I can stock it if I have to go to Sprint?

I apologize if the questions are silly but I'm humble enough to admit I am a noob haha. Thanks in advance for any assistance you folks can offer.

[Epic 4G General] qbking77:
All sprint apps. Tv, NFL, Nascar etc. Think free office. Allshare... all of those are gone.

You will, but you need to make sure you back up all your apps using titanium backup as you might have to do a factory reset to do so.

Go to youtube.com/qbking77. That's my channel. Find Root using one click root 3.0.2.5 and do that. After you do that find me and message me and I can help you out.

Also in that youtube channel there is a video on how to properly use odin. That is how you will get back to stock in case you need to take it back to sprint.

yes for waranty i dont know whichi sbf where in my phone when i received i just know that te boot sign was white not red it had no blur name was 2.1 update 1 and i have made myself a nadroid backup aswell
[Defy General] salingpusa:
If you havent flash anything yet, just check by phone status. Then go to dev forum for defy and look for the sbf there. For the easy way, just unroot, then wipe and check if there are still apps that uses root that still remains like recovery and super user

Now I just purchased one for my father.

And his screen is much better, may be it is just the calibration

But the color seem more bright, vivid and white.

the color of mine is more yellow.

Just a thought

May be Samy improve for the last batch

May be is only that i don't have chance and the 2 first i get is like that.

In fact i don't see a band like other thread mention, it just like calibration thing.

i don't think picture would reveal that small details, and will send his phone to the dad day.
