Battery is really bad after jailbreaking

[Vital]

Hello,
I jailbroke my iPhone 5 (Brand new) iOS 7.0.6 (not OTA), the jailbreak went successful so I continued my regular day. Later on in the day I noticed that my battery was on 6% (After playing about 30minutes of Hill climb racing from 100%), I stared at the battery for around about 3 seconds, and then my phone turned off.

I tried to turn the phone back on but with no avail. It came up with the plug in charger screen! it charges normally but the battery runs out really quick.

Any ideas?

Thanks

Provide an AppList export, and a likely crash or system log that crops up in Settings > General > About > Diagnostics & Usage > Diagnostics & Usage Data that corresponds around the time during the battery drain.
