Humongous power drain

edited September 2020 in ZenFone 5 Series
Model: ZE620KL

Rooted: No

Well, few months ago I complained about the fact that the battery life dropped from two straight days to one day. Over one single night.
Yesterday I updated the phone to Android 10 expecting this behaviour to be sorted out. What I got was very unexpected and surprising.
Now the god damn phone dies after 7 hours. Right now I am on 200km trip and need the phone to work. I sure know that the phone will die halfway there since when I woke up 5 hours ago I unplugged the phone from charger and now it has 24% of battery
Also, why does the phone consume almost 5.5GB of RAM? When I got the phone it needed 1.5GB and the phone lased 5 days straight.
Also, battery discharge rate of 700mA continuous with 1.3A is NUTS! That is 5W of energy!
I don't know what is up. Sure this behaviour looks very suspicious. Almost like the phenomenon of phones slowing down estabilished by Apple iPhones. The Christmas is coming and phones all across the globe suddenly got their battery lifespan severely lowered.
Please, sort this out. This is just getting riddiculous. I seriously don't want to buy new phone then this one is still like new.

  • I had problem with battery draining after update to Android 10. In my case helped to disable Facebook App Installer, Facebook App Manager and Facebook Services. Now I have more than 7h SOT Attachment not found.

    Try this same, maybe it helps.
  • I've uninstalled those both fb app you mentioned.
    But still after that I'm getting only 4 hr SOT (Location disabled, mostly using web via LTE)

    In Android 9 I used to get 6-7 hours of SOT

    Hmm, I have two SIM card, LTE, WiFi and BT always on. GPS turns on only in car (minimum one hour every day). Now i have more than 4h SOT and still 38% battery. Maybe ther is other app on your phone which draining battery.
  • Hi krivanek.prilohy,

    Please check if you have enabled "Backup & sync" in Google Photos. If yes, please also check if the syncing process is done.
    If the app cannot finish the syncing process, it may cause battery drain in the background.
    We would suggest that you disable Google Photos and check if the battery drain problem is improved.
    Thank you :)

    Hi Safal,

    Does this problem usually appear when using the phone or when the phone is in sleep mode?

    If while using the phone, does battery drain while using any specific apps?
    We would suggest you clear the background apps, and check how much battery is consumed from 100% after using the app for a certain time (e.g. 30 mins or 1 hour.)
    Please show me a screenshot of the battery usage after testing.
    Settings > Battery > Tap battery icon > Battery usage.

    If there are battery drain issues in sleep mode, please kindly follow the steps below and show us the screenshots.
    1) Charge the phone to 100% before going to bed > remove the charger > Clear all apps in recent app list > turn off screen > the next morning before using the phone, please screenshot the two pages:
    a) Settings > Battery
    b) Settings > Battery > ""Advanced battery usage"" (tap the battery icon to access)
    2) Tell me the battery variation: for example 23:00 (100%) > 08:00 (90%)

    Thank you :)
