Switch off data. It helps alot. My phone can stay 15 to 16 hours under minimal usage with 5% batt consumption only.

Average about 10~20sec on cold start
4~10sec on hot start
with jve modem n gps aids with brute force few day ago
even indoor

But I feel jve modem is draining battery abit...

Just normal sweethoney.

reboot your phone to try again and on data with sensor aiding function.

Hey guys, anyone sent their SGS for warranty before? Do they allow if I am on custom roms/rooted and such?

nowdays Samsung does e-warranty
upon purchase, they (seller/shop) will send ur phone IMEI (through sms only) to Samsung to register the warranty.
they dont do any IC or anything if i'm not mistaken

to check ur warranty status with samsung
sms this

<PC>SPACE<IMEI> to 33802 <celcom line> or 62002 <digi / Maxis line>

good luck to you this brave fella..haha..
anyways, if u cant get into download mode or recovery mode, we cant help much also..
but hey, what is debus a8? and mind tell us what the step u do to make it become like this?

That's weird, I find that JVE modem > JQ1 modem. Was outside earlier at Coffee Bean Belissa Row (Penang), opened Google Maps with JQ1 modem and it locked me in about 200m plus away from my actual location. Booted into CWM and changed to JVE modem and then I got locked in about 10m away from actual location. Will stick with JVE to see if battery life is ok or not (probably will be ok since I have a bigger batt now ha ha)..

Update on the Momax 2700mAh batt - left charger with 100% at 9am, 50% left now at 11pm with my usual usage (10-15 mins of calls, 3-5 SMS, 15 mins of whatsapp chat, approx. 45 mins of reading FB and Twitter via Tweetdeck and Miren web, lots of reading Gmail and some Gtalk + Youtube activity. Digi data connection always on, WIFI always on)
