Can somebody help me with similar setting for Reliance CDMA

Hi I am not sure if this is the right forum to post this issue. If not request you to guide me to the right place. I am using an Epic 4G with R-network. The problem with my set is that once the battery charge reaches below 50% the phone will suddenly get switched off during call. After a restart after a few minutes it'll continue to work without recharging and if keept idle for some time it'll slowly start regaining the battery capacity to the level where it has fallen from. I think I first notice this after an upgrade to EL30 form EC05>EI22. Presently I have FC09. This happens during movie recording and also sometimes when the flashs works with the camera. Another thing I noticed is if the battery is less than @ 35% then this problem is not noticed. I have done factory reset, wiped the "batterystats.bin" and what not but no solution.One thing is sure- the battery is healthy, otherwise it should not regain to the charge level before shutdown. I would like to know if anybody else has observed this problem and the remedy if any. Thanks in advance Regards HKP
