sounds like more of a phone problem, try restoring your phone to new phone and see if that helps, if you don't want to, try a hard reset first.
if not then maybe you can try bringing it to a reseller store like epicentre see if those dudes can help you out
if all else fails, bring back to digi and ask them to check if its their sides problem, if not warranty time i guess =\

Added on January 5, 2012, 3:05 amhey anyone else notice their battery life has become much better after using it for quite a while? i stopped checking my battery time, last i remember was only like 5hours on a full100% charge
then today i felt like checking
this screenshot taken RIGHT after i connected my phone to charge
whole day i didnt charge
from 100% at 8am until now 3am it was 5% then when i connected i saja saja wanted to check and i was shocked at how much better it appeared now
is this possible? after using a li-ion battery for a while, it becomes better?  [attachmentid=2623227]
