I have inserted a 8GB SD Card in my Optimus 4X HD and since then only GPS enabled my phone loss abt 5% per hour battery. For me it is a big shock to only last a day at best as usually my old phone which is way smaller last for 2 days on battery...really awful but if I remove the SD Card and use the replacement battery got from MPJ, the battery life is awesome.
Is the SD Card fautly or something wrong with my phone??
