I prefer get those higher mAh and with at least 1000mAh output; Most of the portable charger is 500ma, which is very slow, but useful as a backup/emergency.

Here's a lot of choices available:

I reset my set last night. I hope it won't happen again. If anything, i think it's firmware stability issue not hardware.

that one everyone already know already...how about put this...
808 > SIII 

in andriod thread 

I never notice any battery drain issue. But then i rarely use the phone for calls, sms etc. The data usage only for whatsapp and maybe auto update checking.

for those who interested, pls view my WTS post @ http://forum.lowyat.net/topic/2391096

let's wait D600 release and performance test first 
even now nikon D3200 is 24mp, it is like setting lowest benchmark that newer camera should not lower than 24mp haha.... so big possibility D600 will be 24mp i guess... because D800 36mp is over kill... in RAW file la.

wait D600 first haha... when change liao DSLR, the 808 already drop till maybe 1.5k?

808 Meet S3

I suggest u to take lumia 920. coz soon will be win8 era. pc win 8+tablet win 8+phone win 8=GG

when i got my 808, i thought i would sell off my S2.
but i decided to keep both, cos my S2 works better as a mediaplayer when hooked up to my TV
and of cos the fb, watsapp on android is better written than on symbian.
i really hate it when on the 808, after closing fb / watsapp, and then close the data connection...a 'mobile data off, no connections available' crap keeps popping up over and over and over and over again preventing the phone from going to standby...even if u kill the app from appstop or whatever.
of cos can always keep the data connection on but it just kills batt.

throw away your 550D, get sony RX1
or nikon D800/ D600, or maybe canon 6D...

then get s3... camera sound not so important to you, it is not like S3 sucks  to max...still decent la. just not good compare to 808 of course.

like you need high megapixel to crop or do heavy edit or something? usually we just snap and upload right? not even bother to edit colour etc all the time?

instagram all the way
