my phone Qmobile Noir A10 (pakistan brand same as micromax canvas A 110 of india brand)

i have rooted my phone, made a backup but that backup i cant access or use it.
this is the name "userdata_20131227_090252.backup" any help would be great.

now as my phone was lagging again and again, i formatted through backup and reset to factory data reset and also did drm reset too.
but this did not helped. lagging was their, without installing any app only had the reinstall app.
second i tried through cwm recovery and TRWP recoverey, wipe cache, dalvik cache, n system with it. and reinstall through a another person stock rom of same phone, but nothing lagging is still their without any app installed (except which was install within the rom).

So how can i fix this issue, for good.

Also whenever i shut down my phone n restart it my battery % is different all the time. sometimes it is low n when next restart it is higher. so not sure what is the issue here?
