Now also I am using this phone.I would like to say about mainly battery backup, storage, hanging up and heating up.Battery backup will reduce month by month when you start using this mobile.They will 16gb storage and finally it exists with only 10gb, after using some days in that 10gb7gb will be fill will apps and apps data
Finally you don't get storage to store your data.
While charging, using with less time it will heat up. Furthermore definitely it will if you will clear your ram and rom.
