My phone just announced OTA upgrade, and description says minor bugfixes.
Any detailed information?

Just asked to the tech team, waiting for an answer 

+ fast losing charge

Admin, you can tell tech team that this update turns phone into paperweight.
My phone does NOT charge anymore except if turned off. 
And even then it went from 0% to 0% in four hours.

I tried all combinations of charging I could imagine: 
- original wall charger with original cable, 
- PC charging via microUSB and adapter
- original wall charger with microUSB and adapter
- PC charging via original cable

All I got was red charging light and 0% charge.
If phone is turned on, red charging light is blinking and battery is NOT showing any charging however I connect phone.
Each combination was given at least 30 minutes to show any charge different from 0%, but noooo...

I'm sorry to head that, it also happened to some people after the January and march updates. I reported that to the tech team.

Any solution?
I will try to downgrade FW.

On the bright side... Phone was turned off and connected to power bank for the last 12 hours.
And behold... battery is at the 54%. 
Problem is, power bank was new, fully loaded PQI ABG-100B 7800 mAh with original phone USB cable, so phone battery should be at 100%

Downgrading FW ASAP.

Yeah, downgrade to your previous firmware before you totally drain your battery!

So far looks like downgrade to 20171227 was successful, battery charging from PC via USB!
More info after few recharging cycles.

Remember also to perform a factory reset after the downgrade.

Should I install this update(via OTA) when I have version 20180124?
