Ok 3 hrs screen on. With 40% bat life left. . 24/7 data.

Lowering brightness to 20% or less than30%
Significantly improves battery life

Yea nt much different Cox NW.my CPU n gourmet heavily undervolt

Lol for me no much difference between 800 n 1.2 lol. Both allow me to open up big excel n PDF file without lag. Dual core here we r talking about.

Yeap yeap . Significant reduction in heat production. I'm quite happy withmysetting now. Can very reach 4 hrs of screen on even more with single charge.
thanks to pro here who made me pro to some extent

i was suprised initially when i downclocked da cpu, there wasnt much change to da UI fluidity ( to me no difference, lol). i can even feel sluggishness (very minimal) in htc sensation most likely due to sense..tw+gingerbread do not need 1.2ghz.. let alone dual core

where can i get nice bookmark widget for android that displays preview... I miss those widgets i had in n900

wanted to download today... too bad da server was down

ok 4 hrs 10 mins left 15%... off to charger now...

ONE tip for all ... lower da brightness to about 20-30%..below 30%.. u will see significant battery life improvement

screen on time... my target

i presumed that's time since unplugged... i think ur screen on time around 1-1.5 hr ..check under display

Going da ignorant way 3g 24/7.. lol..

Lol 3g 24/7 battery sucker to da Max. Lol

i suggest u read n watch video.. double intelligence is better than one..

google ChainFire root for sgs2..read thru.

video - gadgetcheck how to root on youtube

CF root is da easiest with odin..

Less than 5 minutes including removing yellow triangle part.. this is rooting process as downloading part would take longer unless ur internet speed is fast

under mobile n network settings>mobile network>network mode > chose gsm only
or go to market download 2g/3g toggle widget by curvefish ..useful

Checkrom revolution quite hot in this thread...
another one u can try check my siggy

whats ur ROM? have u tried rebooting ur device?

I also cannot tahan
. Used other browser... dolphin still da best la

androidmeda latest rom has improvement on performance n scrolling speed..yea finally something that will make me download and flash

lol androidmeda has been releasing updates for the past 1 week.. those updates are to fill holes from previous release lol..

what's ur screen on time? u on data 24/7.. battry drain during sleep?

ok... i think fb chat is giving u wakelock...erm try close all active chats .. or dun use them at all ..

juicedefender also givs u abit of wakelock...

is data on 24/7 with HSPDA... what's ur line? digi?
3 things that will drain battery on anyphone

1)bad signal, using 3g all da time
2) screen brightness
3)apps running background preventing phone from going to sleep..

here's a 'standard' u can folo.. assuming u'r on stock rom.. with fb polling background.. setting data to edge..

battery lever shud drop 1-2% per hour or 1.5.

things u have to differentiate.. battery drop during sleep (screen off) vs battery drop during screen on (usage with 3g,dun include games..tey are born to suck battery) vs both

most of us here try to minimize the first... (priority 1)

screen on usage is highly subjective (things that can be controlled ...brightness set to below 30% disabling autobrightness, using EDGE instead of 3G)

changing da charging rate frm da kernel is rather unsafe in the long run.

assuming da circuit that breaks the charging is built on da main board (judging frm da ability to software tweak da charging rate) it's generally not safe to increase da current as the operating current is inversely proportional to the life span of some components

about the circuit - it functions to cut off any further charge to the battery(in other words, to prevent them from overcharging) china made batteries lack this circuit or have defective circuit, so they tend to swell up when overcharged..

Maximum current output for USB 2.0 is 500mA. since output is fixed, there is no way to trick da phone into taking more current. unless u use usb 3.0 (900mA) output

some portion of the current will be lost as heat, that's y battery heats up during charging. it actually decreases the charging efficiency therefore it is better if u place ur phone in cooling area while charging.
