No . rooting will not affect and create such issues
3rd part dubious apps ESP cracked pirated apps will often cause such issues

i can only feel the warm on the left hand side.but not critical. still can surf smooth and no lag.

Anybody have any comments to the battery life? Mine seems to be drained at a very fast rate. For example had it charged to 100%. Used for a 2 hours on and off (light browsing and FB) and its down to approximately 65%. Then overnight and it drops 10% to 55%.

Had all the settings under control (GPS off, airplane mode, minimized syncing, brightness at reasonable levels).

Read some threads on Xda and seems like calibration is required. But my understand is that it is only required is custom ROMs are involved.

Any comments?

Actually mine weren't intensively used at all. Just light surfing and FB. I do have my email Exchange synced but that typically doesn't impact the battery adversely.

do checkup my official thread sgs Ii page 1 FAQ section q16-16d to understand better battery issues. dont think is battery problem. it is more how you manage your battery

Steven, I have similar experience as your with regards to the battery life. I am amazed that everyone is getting good results. For example last night I started at 99%. Within 30 minutes tinkering around the tablet, I'm down to 89%. Seems pretty quick.

At first I suspected maybe mine didn't have the 3G SIM in it and I had the GSM radio on causing it to drain as it tries to detect the SIM. So turned it off, but it doesn't seem to make any difference.

dun look at the droping of 10 percent.... try to monitor from 100% - 0%, how much u can get the juice out of it. i have my set to , no force feedback, no sound while typing exept using the dial pad. GSM whole day except i m out and no wifi available then i switch to 3G. screen brighness i set to auto. push mail on exchange, facebook update.  try and see to monitor from 100% - 0%. use as per normal to ur usage then u will know ur usage will last how long. then only u know ur tab can last you how many hours base on ur usage.

also remember to use task manager to close unactive application. if u open too many application, u will drain lot of battery. expecially free apps....u will have it connected to the net to pull the ad if u allowed them to hav ur syn active all the time instead of manual. i only active push mail immediately for exchange, the rest i set to manual.

if i put my set on idling from nite, lets say full charge 100% at midnite 12.30am, then i sleep, wake up go office around 8.30, i will have like 97% to 95%...

under setting>sound>uncheck haptic feedback
also uncheck screen lock sounds and uncheck audible selection
GSM whole day means i will set my phone to only on GSM mode if i dun need to use the tab to surf net. office i no need to use the tab, i can use my notebook to go to the net and also i try to connect to wifi available at cafe or restaurant..if not available then only i will set to 3G mode. i only push email from exchange and gmail. i did not add hotmail and yahoo inside. yes, i use facebook for social hub. and i did download facebook for andriod...but i did not syn that one..whenener i wan to see some update from facebook i will use the build in social hub widget to manualy sync it. and i syn with GSM ( edge).

my digi is unlimited internet also..i m using digi business plan. but i wan more battery power..... so, u got to choose.

where to buy case for dis monster?

glad that u got what u wan...try put it idle, off ur wifi when u sleep and also change to GSM mode only...u will love the battery power!!!
