        Pixel 3a from 100% to 94% in 6 Hours.
        Xiaomi Redmi Note 9 pro 100% to 43% in 6 hours.
        ASUS Zenphone - 100% to 94% in 6 hours.
        OP6 - 100% to 79% in 6 hours.

        Xiaomi Redmi Note 7.... And more...
        I have too many devices...

          On Xiaomi POCO X3 NFC (surya) , when I made the MR17, one month ago, I had measured a battery endurance of 34 hours (devel channel).

          Now, after OTA-5 (stable channel), I measure a 22-hour endurance…

          These 2 measurements were made in similar conditions: only phone calls, SMS, messages written on telegram, and web browsing with morph (no Wi-Fi, Bluetooth, NFC, VPN nor Waydroid)

          The problem has been discovered and confirmed by @Boldos , on the ut_pocox3 TG.

            It is my impression that this is the case on my Volla 22 as well. Stable release.

            Volla 22, Xiaomi Mi A2, Nexus5 (backup)

              Hi again all-

              I have been experimenting over the last couple weeks, and think i have found a couple patterns.

              1: After @Mario-CH 's suggestion, i tried leaving the phone off for 20 seconds, then rebooted. Sure enough battery performance was much better, and overnight (7-8 hours) i only lost about 5% from a full charge. However...

              2: The phone definitely drains a lot faster when it's using data rather than wifi. But, simply turning off wifi doesn't do it. The phone (not sure if it's the fault of the Pixel 3a, or UT, or my provider Freedom) does not reconnect to data immediately after turning off (or losing) wifi. It says it is connected, but I I always have to open up Mobile Settings and toggle network types before it "kicks in" and starts getting data. Once it does that, then battery usage goes up significantly, about 7% per hour, even when i'm not actively using it, all apps closed, screen off, etc.

              3: And then if i re-enable wifi, data usage goes down to normal again.

              So, i think my battery is fine, and i think on wifi it behaves well. But is that kind of drainage for data expected? And why does it not smoothly change to data working when wifi is lost or disconnected? (It always requires me to toggle the network type to get it to start working.)

              Anyone else experiencing any of this type of behavior on their devices?

                Hi,

                Anyone else experiencing any of this type of behavior on their devices?

                After @Fizz's post, I've done two measurements (on my Xiaomi Poco X3 NFC):

                1. With Wi-Fi off, data on, I measured 27 hours of battery lifetime.

                2. in same conditions, but with Wi-Fi on, data on, I measured 38 hours of battery lifetime

                    Hi @Fizz

                    Interesting that you get the opposite that i do; i get longer battery life when wi-fi is on.

                    I get longer battery life when Wi-fi is on : 38 hours…

                      Interesting! Are you running the Battery Saver app?

                      Is currently using an Op5t
                      Also owns an Op1, a BQ E4.5 and an Xperia X, as well as a BQ tablet and a Pinetab2. Please, someone... make it stop.

                        No. Not during these tests.

                              Hi,

                              As suggested by @Fuseteam, I disabled data connection and I did a new test (still without BatterySaver app):

                              1. Wi-Fi on, data off : 38 hours of battery lifetime

                              Same as Wi-Fi on and data on.
                              It seems that the data connection is not used while Wi-Fi is on.
