Very bad battery.

- Model Name: ZS661KS
- Firmware Version: 2009.99
- Rooted or not: not
- Frequency of Occurrence: Always
========================================
I've been having issues with my battery since I got my phone but just thought it was a rogue app as I was losing about 2-3% per hour without using my phone but over time that grew.
For the last 10-15 days I was losing 40-60% battery during the day (2-3h Screen on time) and over 25% battery overnight for 7-8 hours while I slept.
So I've finally got around to doing a factory reset this morning and for the first 4 hours I didn't install anything nor really use my phone and there's a really strange dip (rise) in power consumption.
After 4 hours I installed FB, Duo and Snapchat and here is the 8 hours worth of stats so far.
I'll post how tonight's battery drain goes tomorrow but I'm just wondering if anybody else is having issues and had it fixed with a replacement phone because I think that's my next step.

You got terrible battery ussage, lock at mine. Contact asus service and talk to them
What is ur firmware version?
If you're worried about the health of your battery, please contact service. If you want to do some more troubleshooting, charge your device to 100% and put it in flight mode before going to bed. Note the time and check your battery consumption in the morning.
.99 is My version
I went to sleep at 37% and woke up 6 hours later on 8%.
After the first screenshot of battery usage I had a 30 minute video call on Duo so that's the dip in the middle.
Do a factory reset, charge to 100% and monitor. If there is still strange dip, send the phone to the service centre.
