Standby is bad . 3-5 hours video or continuous phone calls and high bright settings. 3-5 day stby ( don’t take any manual battery life as gospel - phone location distance talking to network and user, + user settings determine battery life) (Note, some apps you put on may badly drain battery standby consumption running in the background)
Touchscreen function is good and picture quality is great.
Video streaming also good - I can run Youtube & Netflix on 3g/4g or wifi without interruption and tennis streaming is good direct from the web site - not via an app though- adds kill it.
Phone calls work fine, as well as using speaker phone in the car.
Camera like most phones, tiny cameras need plenty of light for quality pictures and video.
No generic faults found. I enjoy using this phone, meets the needs for $100 prepaid price -( note you can unlock free after 6mths generally if you need to change providers)
