Performance and responsiveness in daily usage apps.
4C, P1M and P8 lite are all almost equal with no major difference, despite of having different processing power. None of them have major lag or freezing issues. P1M is a solid performer (better than Galaxy J5) even with just a quad core.
Heating and thermal stability.
All have stable performance. No overheating issues, their peak performance remains consistent, even when used heavily in a hot environment. Overheating slows down the phone.
Camera
1. P8 lite
2. 4C
3. P1M (biggest weakness of it).
Camera is very important in smartphone and for resale value too, but its just personal preferences, like I prefer digital camera over smartphone camera.
Display
Vibe P1M has better, more vibrant and much brighter display than 4c and P8 lite.
Battery timings.
4c and P8 lite have ~4-4.5 hours of screen on time, which is actually considered good. P1M is best for its exceptional battery timings.
Reliability.
Huawei is more reliable than Lenovo, but Lenovo is not bad either. Both are very good.
Sound output
P8 Lite and Honor 4C is excellent and louder. P1M is loud enough, but not that loud as them.
Developer support
No idea about that, as I am totally out of this field now, after working a lot on it.
Led Notifications
They have it which works perfectly fine and blink for missed events, even in P1M.
