hmmm, i thought you guys already upgrade those battery to the bigger one 2000mAH. i've been using it for quite a while now.battery life would be ok coz i always surf internet n play games.
the only - about the 2000mAH battery is that it won't fit into the majority of casings from the market. really saks though.

My ori battery showing signs of old age. Bought 1650mAh oem batt from Brotan RM29.
Not too bad & cheap.

Yes really holding back purchasing Note2 coz of S4. Playing with Note2 earlier @ Harvey Norman really kena pioson kau2. Damn cun device. Hope S4 come quick.

thank you very much.
i did google but search the wrong direction. i was looking for wakelocks, and better battery stats.
and i mainly focus on "no data connection" "no or unknown signal" since they have the highest duration.
thanks again for the tip. i owe you big time.

never thought the answer was in s3 forum.
i have tested and indeed the issue is USB OTG.
everytime i unplug USB otg, it wont ever go back to deep sleep.

the solution to this issue is to NOT unmount by pulling down notification tray and tap unmount.
instead, go to settings>storage, and unmount from there. confirm to work. no wakelock

how much u bought it?

wanted to buy the 2000mAh one, but cant find it anywhere.
glad i didn't bought it.

because i bought spare battery from garage sales.
same 1650mah from Brotan for just rm29

having two 1650mah battery (2x1650=3400mah)
and a external charger, is way more convenient.
grateful that s2 back cover is so easy to pop open.

no worries glad to help.

Cheers and have a happy new year!

i see the word siyah, straight away duwan to download already.
v5.5 serves me well, and jeboo kernel solves the lockscreen freeze and exynos exploit.
the only problem i have left is bad battery life due to unknown wakelock, which is solved now,
its the unmount bug that affects s3 and note1&2. solution is to unmount from settings.

using anything related to siyah and you'll bound to have some sod, random reboot, bad battery life etc.
dual boot and fancy kernel tweaks is not worth having the mentioned issues.
there was 0 mention of sod in disaster rom thread, expect to see lots of them pop out soon.

just take a look at few pages back in this forum,
all the complains about jellybam is related to dorimanx (modified siyah)
as long you use cm10 kernel in jellybam, non of these issues will happen.

Yes this is Siyah v6.0 Beta. Haha.. will let this rom run for a few more days to observe performance. Hand itchy
just want to flash last rom of the year.

I have a moga game controller want to sell. You can refer it on here forum

yeah. and since can get good quality s2 batt for cheap from brotan
i rather go for another one or even 2 extra battery

around rm139 from Samsung authorized shop in JB. i bought it last year. it should be cheaper by now. it depends actually either you want to buy the ori or other one that has near the same capacity.check them in garage sales, should still got there.

i have been planning to buy the external battery charger such as yobaoo brand.but still havent find any that i really bekenan lor.

Among the Sammy base which one has the least bug?
