3days earlier I purchased BlackBerry Z3
Its really amazing phone with fluid, buttery OS
Diplay is also good, most of apps work installed
Amazon marketplace and Mobomarket

Now the thing is my phone takes 3hrs to charge
And in each hour 5-7 % battery drain on standby but my main concern is when I use my phone for talking or surfing net
Battery drains very fast example 10% drain in 10 minutes is this normal??
I have read reviews on net they said phone has good battery remain for one or two days
My software version is 10.2.1.2977

I think it's because the phone is new! Wait for sometime. And also that the 2977 doesn't have the best battery, why don't you try a hard reset!
You perform this by holding the volume up and down buttons till the BLUE BlackBerry logo comes!
This won't delete anything and won't change anything, but will free up ram

Thanks for reply bro
Tried security wipe which take around 1hr
Searched on net for full reset but just little bit better hope BlackBerry will fix this and give update
I have Xperia C also it has got 2430mah battery but it really give superb backup so as compared to z3 2500mah it stand nowhere

did you upgrade the OS since unboxing?

[Rajesh Rathod]

I also had the same problem. You need to reload the OS

What's the average battery backup for Z3

Calibrate your battery and you'll feel later

5-7% battery drop in one hour standby is abnormal.
My Z3 drops 1% per hour (standby) most of the time.

with your data off, shld be 1% in 3hrs

I have reloaded OS but for 2 days it was working well but again BBM has started to consume all my battery. I guess we need to wait until next BBM update
