Camera is quite good and is much better than Mate8, MiMax but is not in the class of say Note7, S7e, LG V10. Even lowlight shots I rate it as above average. Snapping is close to immediate I deemed it good enough for my usage : for sharing on FB, whatsapp I would say most casual users will not be unhappy with its camera shots quality However i will rarely used its camera as this phablet is mainly for entertainment purposes. For my daily phablet it will be my MiMax and at times Note7 or A9 Pro
Best battery life I had experienced to date s Samsung A9pro with SD652 chip n 5000mAh : SOT 13-14 hours vs 9-10 on ZF3ultra, 10-11 on Mate8 n 11-12 on MiMax
so, basically it means that you use your phone actively for 9-10 hrs. whether it's playing games, surfing /k, watching videos, social networking... etc. however mileage will vary as each activity consume battery differently. surfing the web on wifi is different than on mobile data, with wifi tend to be more efficient. watching movie, especially those full of dark scenes, will also tend to be lower consumption than mobile surfing (usually web pages have white background)... these are not always the case though, as physical technology (screen, modem, SOC, etc.) can make the consumption rate differ also...
There is no clear specific benchmark for SOT. So 9-10 hours will be different depending on what you do. Pretty sure if you Pokemon Go the SOT will maybe go down to 4-5 hours compared to its normal operation.
Using this BIG phablet as an alternative to Note 7 or even MIMax ( from another users) ? I hope this phablet fits well into your pocket I only use this phablet as a mini tablet for videos, browsing , youtube etc and not as a daily working gadget I must say I am very impressed with it as an entertainment gadget
