    I got my One Plus 8T on 29th Oct. Been using this for around 2.5 days now. Beautiful device no questions asked. the 120 Hz refresh rate and the smoothness is amazing. Camera takes decent pictures maybe not S20 level but we can get by this.

    Battery usage right now for me is around 5.5-6 hours Screen on time with moderate usage with 120Hz refresh rate and no restriction of apps. The definition of my moderate usage is

    - Plenty of Calls during the day , some of which via either Bluetooth Headset or via Car's Bluetooth Speakers
    - Lots of Whatsapp checking and messages being received. Also a bit of Instagram usage along with Sufficient browsing via google chrome .
    - Since i travel a bit for my work the network connectivity keeps varying between 4G, 3G and sometimes Wifi and little bit of hotspot usage to get my work done.

    I personally feel that the battery life needs to significantly improve. As somebody pointed out here, it might get better with the OS learning about my usage pattern and also with completion of initial battery cycles.

    However i do not expect to get these 8-9 hours of Screen on time that Youtuber's are showing as part of Battery Test. I believe that those tests are conducted without the insertion of a sim and purely on wifi and with just some select applications running one after another. That is not a real life usage scenario. In real life we might use the phone, whatsapp, messaging platforms, bit of web browsing and other tasks in tandem which is far more of a strain on the battery rather than just running a single application for 2 hours and then another application for a certain period of time.


    This has been my app usage pattern for the last 3 days.


    This is my current screen on time.

    However there is something which i noticed that is puzzling me. Whatsapp and True caller seems to be very active in the background as opposed to other apps that is listed above.

    Could this be a reason for the battery drain ? Although these are common apps it is only in this phone i have noticed this metric of 'Background Activity' usage time.

    Please do let me know about this.

    These apps remain in background as they have services that are running to recieve messages and calls.

    After the OTA update to battery is draining really fast even under normal usage. Battery drain was comparatively less on OxygenOS, so I want to rollback to OxygenOS Can anyone please help with full firmware download link for OxygenOS INDIA version.

    Thank you
