I had exactly the same issues discussed here (Battery going from 100-5% in like 3 hours ... buggy system keeps on restarting -crashing ... slow response ... even after running jelly bean ... then i did 2 things ... 1. bought a 5300mAh battery for 20 euros from china ... 2. installed CyanogenMod Android kitkat (CM11M12) ... now the s3 is smooth .. fast .. reliable .. and lasts really long before needing to recharge it ...
the biggest bit of crap thit I ever purchased goes of network 2 to 3 times a day
Battery used to be good but it is deteriorating at a rapid rate :( have had it 2 years
When is battery 0% phone turns off , normaly . When I use the phone after 1 hour , my battery level is about 40 or 50 or more % . It wasn't charge on charger. I hava wi-fi so i think it has wi-fi charging....Someones opinion please ???
ramintm2014, 05 Jan 2015galaxy s3 is ugly but xperia sp very very beautiful yes SP is beautiful, but it lags a lot, you should choose S3, it has amoled screen and also doesn't lag like SP.
Anonymous, 04 Jan 2015battery its a píece of crap , it last less than an hour if i am in facebook1- Facebook and his spoiled son ( messenger ) are killing the battery in all phone brands not only on S3 !!! So advice you to remove ( messenger ) and Install instead of it app called ( FacebookChatEnabler ) After that Facebook will not be required to install annoying ( messenger ) ....
2- Not install many apps that consuming battery and ram such as social network apps or games ...etc, You must know that most of these applications are running in the background even if not used !!!!! Only install what you really need in your daily life .
3- If you are using battery for more than 18 months it’s better to change and get a new one .
The "begining"... Hands down. Love that phone even after those years. Performance, display, camera all great. Only battery is down side but not that much. Sure that in 2015 still will be a decent device. SGS3-The King.

guys i have a question,
is it safe to use a different brand of PowerBank charger to my Samsung Galaxy S3?
BlueLeopard, 03 Jan 2015Nope, it can get 4.4.2. Weird bit true.@ BlueLeopard
Sorry, but you are wrong. The S3 i9300 never has, and never will, get KitKat firmware.
On the pane to the left of these posts click on Specifications and then under OS you will see that it is upgradable to Jelly Bean v4.3
If you don't believe GSMArena then go to Sammmobile:
who also state that the i9300 will never receive KitKat.
If you don't believe GSMArena or Sammobile then head over to Samsung's own servers:
There you will find firmware for every country that Samsung has released firmware for. Not ONE country has ever received KitKat on the i9300
The parts are damn expensive.. my LED screen went out & now I might as well buy a new phone for as much as the screen costs!
gwh, 02 Jan 2015Android 4.4.2.0032 messed up. Phone shows EST time & calendar, but alarms go off 6 hours e... more@ gwh
What is even stranger is that the Samsung firmware for the i9300 never went above v4.3, yet you claim to have v4.4.2.0032 on your phone.
Something isn't right, and I think it is YOU!
