[5z] Bad Service! Battery Changed 4 Months ago and now it is very Badly Degraded, Seeing Idle Drain.

Model Name: ZS620KL
Firmware Version:100.10.107.123
Rooted or not: Not
Frequency of Occurrence: Daily
APP Name & APP Version (If your issue relates to the app): Hardware issue related to new replaced Battery.
On February 24th i got my battery changed from authorised service centre by paying a certain amount thinking that i can use my Zenfone 5z for another 2 years, even when i was getting normal 4hrs of satisfactory SOT for normal use from my 2.6 year old original battery.
About Changed/Replaced battery :-
Until 4 months there was no problem with my changed battery i use to daily get 6hrs of SOT for normal usage. And there was no idle drain.
From last 15 days i started seeing a lot of idle drain issue where i always need to charge my device for 2 times in a day (4 months old new Battery). So here i thought it may be a software issue and i still awaited and tried many battery restricting features for day to day usage but nothing helped and belive me i use to put my device on charge daily with battery care features i.e scheduled charging,Switch by battery level,Dynamic charging upto 80% and many other workarounds but still behaviour of my battery remained as it is. And with frustration Later after 12 days i decided to factory data reset to see if that will help. But issue is still the same.
After Factory data Reset :-
Behaviour is still the same even after using all battery caring features,even i use auto start manager denied all apps and also have restricted many apps but no help.
Now what i am seeing is if i dont use my phone for so long or u can say if it is kept idle/Standby drain keeps running in background while super clean feature for all apps is On, as soon as i lock my device Drain is continous. you can say for for every 1.5 Hr of idle time battery drains 4-5 percent approximately.
Daily while i Go to sleep i have turned super saving mode On, what i see is if i keep my battery 20% before going to sleep at 4.30am until in the morning when i wake up at 10.30am i see that my battery is 2-3% remaining or sometimes phone is switched Off.
Now here i really doubt if my replaced/changed battery is original. Which is provided by authorised service centre. I trusted Authorised service centre for Original battery and so i decided to take a chance and what i now see is something fisshy here even after paying so much to replace a battery. How can a origianal battery degrade soo much just in 4months after replacement?? While my old original battery which came with device use to give me 4hrs of SOT even after 2.5 years of usage before replacement.
Here are some proofs with date and time how battery is degraded and keeps doing idle drain while i was working for long time without unlocking my device (Auto start manager all apps are denied)👇:-
At 4.55 pm 50%

At 6.20 pm 46%

At 8.03 pm 41%

Now at night while going to sleep :-
At 4.25 am 20% (Super saving On)

At 10.58 am 3% (Woke up)

Overall SOT i am getting for normal use (4 months old battery only)👇:-

Battery page doesnt show that idle drain i dont know why,but aside battery starts to drain continous in the background as soon as i lock my device. 🥺😰
I never had any issues with my Zenfone 5z till date but just taking my device to Authorised service centre to change my battery by trusting them ruined my all Flagship experince and now i am frustrated with such backup. Is my replaced/changed battery not an original battery..??
help me with the solution my battery is still new. I am sad with spare service.

Update :-
I got a call yesterday from mathews sir and his authority head chetan sir according to both of them battery tests are getting passed and as they dont have any authority to check with motherboard as it can get dead if device is out of warrenty
So now they have offered me the change of battery again and they said as you are not satisfied with our service we are ordering a new battery again for you but here i think my issue will still remain as it is because last time battery was changed and problem stayed as it was, so now i think if its board issue they said i have to pay 80 % of board cost in advance and they will check with board. Those were two options i was offered then i told them change of battery is the only thing i can afford for now..!
I dont know my problem will get resolved even after this new battery installation 😞 if problem stays then i have to use my device with idle drain issue as it is.... 😞
I hope in future service centres will change its policy of not touching board for out of warrenty customers... Because most of issues reside on boards or else customers will get unsatisfied as i am....:(

My wide angle has stopped working all of a sudden and yet I don't care much of going to service center coz in 6-7 months I am anyway changing my phone.
The SC near my home is a outsourced one where they don't even have the tools to open up the glass panel, thus not going there. (Joke brand, I live in the capital of India and even here they have just a single official SC)
The exclusive and official Asus SC is far of that my half day would be wasted there and who knows what would be the end result, whether they ask for money or do it for free (courtesy of device being 3yr old)
Move on bro, this 5z was plagued with issues from the start itself like no SIM issue, camera blur issue, not fast charging issue and what not...
Even if the ZF8 comes in India, the 4000mAh is not gonna make it, atleast for me... So probably first and last Asus phone for me

Same, man.
Wide Angle camera stopped working, all of a sudden.

Response is to take it to the service center.
Anyway, I am also going to change my phone, so not going to spend a single more penny on this one.

Same issue wide angle camera is dead and battery is weak . I got the device just a few days after launch & it is a good device with pathetic service & support . Looking at the service experience of 2-3 guys visiting Asus outsourced service centers seem to be dangerous for your phone 💀

Is Asus deliberating doing this?
Bad battery backup, I can understand, after three yeas, but wide angle camera not working suddenly is weird.

We can take a survey and then report it to tech websites and other authorities.
