The first impression is very good; The phone is very well-built for the price.
But that impression quickly disappears as soon as you start the phone.
Let's start with the positive ones. The screen is good, something I definitely did not expect. Obviously not in class with phones in higher price ranges, but still far beyond expectation.
The phone's battery life is the next positive surprise. In moderate use it will last for up to 2 days. Worse is it with the charging time; It feels like it takes infinity to charge the phone when it's used to it not taking more than half an hour to charge the phone. Here it takes about half an hour per 10%.
And there was an end to positive aspects and it feels like it's time to sneak into the slightly worse aspects of the phone.
Huawei has chosen to stuff the phone full of its own apps and various other things that no healthy person would like to touch. Fortunately, much of the junk goes away, apart from Huawei's own apps then, of course.
Under all this is also Huawei's customization of Android "Emotion UI 5" and it has to be one of the worst experiences I've had with Android. Fortunately, you can fix most of the problems here by installing your own launchers.
In addition to this, the camera is so bad that it would probably have been better if instead they were completely incorrect to install it. It is basically useless even under good condition.
Performanceally, it is under all criticisms; Sometimes it's quite rap, but for the most part it's slower than a phone from 10 years back. It may take 5-10 seconds for the phone to turn on the display only after touching the fingerprint reader. 15-30 seconds to open an app. Sometimes it locks for several minutes. Have tried everything to make it respond faster, but not even a complete reset keeps it crazy for many days. Terribly frustrating!
All in all then? The Huawei P9 Lite is not a phone I would recommend for everyday use. If you do not do much more than scrolling a bit on Facebook and calling / texting, it may be enough, but otherwise I would probably see the phone as a cheap backup phone for the emergencies.
