Hi,
I made a screenshits that you want plus a screenshots to 3c battery.
The strange thing is alth ...

Thanks for screenshot.
This what I can see is that your phone last 1 day and 18 hours including 5 - 6 hours screen on and 1h calls. This is good result. About wi-fi please go to settings - wi-fi - switch on wi-fi  - top right three dots - advanced - keep wi-fi on during sleep - never and network notification off!
This should deactivate wi-fi from list.
Could you please perform factory reset, charge phone to full from 1% and discharge how quick is possible maximum in 24 h.
Also you can use SPFT and flash phone.
This looks like be incorrect system calculation or some system bug.
Here is SPFT instruction

And here all available ROMs

Please give me update

Hi,
It is just 1 day and 8 hours not 1 day and 18 hours.

According to the wifi, i already disabled these features as i knew from this forum about this issue, but the system show it is always on, the good thing that it doesn't consume power.

According to the battery and the fast drain after 30%, i think also it is a bug in the system calculation, as now while i write these words the system show there is still 69% but when i summed up the computed power use  ( in setting>>battery option >> then choose each application) for all applications and other stuff like screen it give me 2080 mAH which is more than 50% not just 31%(100-69).
I don't know if my method to calculate the power drained from battery is correct or not, you can advice about that.

According to format the system i will do this after some days and feed you back.

Thanks for your support

Sorry but I picked calling time as stand by time as 1 day and 12 hours and I added 5 hours of screen on.
Please don't look on mAh details as on most devices this is not calculated correctly.
Detailed which is system calculating are on background and in hidden partitions so without rooting phone you will not get access to see this.

\n\nToday I tested it again (it's hard to post screenshots from the phone in this forum).
With the app you suggested it can be seen that it drops REALLY fast after 30%. I was sleeping and it went from 40% to 30% in 4 hours. Then it went from 30% to 20% in 30 minutes, all of that while I was still sleeping! The phone was doing nothing more than from 40 to 30! I woke up when it was at 10%, and it went from 20 to 10 in 30 minutes, all while I was sleeping.WHILE SLEEPING:
40 > 30: 4 hours
30 > 20: 30 minutes
20 > 10: 30 minutes (then I woke up).
It's a PROBLEM.
I flashed it.
I reset to factory
Nothing solved it.
And it's a problem you can see in ANY UMI PRODUCT.
So I think it's probably something in the software, because batteries are all different yet the problem is always the same.

''And it's a problem you can see in ANY UMI PRODUCT.

Those two statements are obviously very far from the reality. It's not even a general issue of the Plus E. How could you know about all units of all models of UMi? Most users talk about the great battery life of UMi Plus E and basically that's the highest battery life UMi smartphone currently.
If you've really flashed your phone with SP Flash Tool (in Firmware Upgrade mode) but your issue still persists, then you probably have a defective or at least not perfect battery and the solution is to replace that defective battery. In a specific case if your battery lasts enough long time anyway, you might have a wrong calibration data saved. You might fix it by flashing the latest ROM in Format All + Download mode but in that case you have to re-write your IMEI numbers with the SN Write Tool.

It cant be a defective battery because it still lasts more than 24 hours.
If you tour the Z Pro, Z and Plus E you can see others complaining about this (dunno about the previous models, I haven't checked the forums).
If it was a faulty battery one could have seen it in the whole time, not just in the latter 30%: it seems something's running off in the system that drains the battery super fast, like some kind of software protection for the battery to not make it run out 100% so its life is actually longer. It seems like something artificially drains the battery.
If it were a way to trace WHAT is causing the power drain I'm pretty sure it would be something of the system.
I had a faulty battery on my iPhone, yet the OVERALL power consumption was too fast, not just at the end.
And you can see many people here with this issue (in this thread and in Z, Z Pro forum), everyone complaining that it happens at around 30%...
The most honest deduction from that is that there's something in the software that's either not showing the correct battery usage from 100 to 30 (like the software is overestimating the battey capacity in that period, like it's actually draining 100 to 5) or something's draining it way too fast at 30%.

Sorry but I can't see. Or we should match the number that means "many".
I suggest you to process that Format All + Download type flashing.

@bencebacsi
Can you tell me which files I need to rewirte the IMEI? The turotial says "Modem_1 database" and "AP database"
