Hi everyone
Since the day i installed latest Nougat on my p9000 i had problems with battery drain and after writing and reading a lot of forum threads,
here  http://bbs.elephone.hk/forum.php ... age=19#.WR8HhWh96Uk
and here  http://bbs.elephone.hk/forum.php ... age=22#.WR8Hw2h96Uk
i have solved battery drain on P9000.

The problem was the bluetooth battery drain  so to solve this i had to resset application preferences in settings. But than the same problem showed with Cell standby battery drain, so i had to change network selecting  to use only 3G and 4G without 2G and since then i dont have battery drain problem. I have made that in MTK settings change using MTK engineering Mode app from google play store.

and here are screenshots after no more bluetooth and cell standby battery drain problems.

For bluetooth you need to reset app preferences in phone settings -apps and then in 3 dot menu you reset app preferencies, but you also make changes in mtk settings under sim 2 you need to put only 3g and 4 g without 2g as shown in photo.

I have almost forgot, that i made this change also in cellular network settings. Screenshot_20170519-174302.png
I clicked on preferre networks and then click on whatevere is your network

click on it and then you will see network ID and network type

Click on network type and check all of them (or only 3G and 4G) in my phone before there were checked only 2G and 3G so i checked 4G also, and then in three dots menu in the corner to save.

so this is also the change I made by experimenting so I m not sure if it has any effect but now i have solved problem with bluetooth and cell standby battery drain.

it depends on ussage, sometimes shows 6 hours sometimes 3 hours if you play intensive games, it depends, with screen time on it still sucks but at least there is no battery drain in standby
