Battery problem after enabling battery percentage with ibackupbot

My battery on my iPod touch 5g drains faster after I added the battery percentage with ibackupbot. Does anyone who did this have the same problem?

Before my battery drain to 93% of constant usage ( wifi on,checking email, browsing safari, etc ) in about 1 hour and 25 minutes; now it goes to 93% in 45 to 50 minutes.

Also when I charge my iPod it gets only to 95% and stops charging, and when I unplugged it, it reads 99%.

Please help if you guys know how to fix this..
