What is your firmware version?
You can find out by going to:
Settings - System - About phone
Post software information.
Here is that information
Thanks, can you take a screenshot of the Battery screen too?
That information?
Settings - Battery
And then you should see list of apps with battery usage.
If you want a better battery, i would advice to downgrade to A9 since i am currently on A9 and i see a drastic change in battery usage. Lasts easily 15+ hours of youtube and 20+ hours of Screen Off Time.
There is!
Great thanks!
If you go back to Settings - Battery - Power Master and choose Auto Start Manager.
Disable all apps but the ones you want notifications like WhatsApp, Discord, Telegram.
Pokemon Go you should disable because it is constantly using Locations which is probably why you have this draining even though you're not doing anything.
Even though I leave my Locations on everytime, it does drain more than it is turned off. So if you have no use for Locations, you should turn this off. Locations should only be used if you're using maps to navigate or Pokemon Go.
Apart from that, the usage looks fine to me except the gap you have in the graph, which probably suggested you turned off the phone and started charging.
Thanks for your time and troubleshoot but that information shared was after my post here so I don´t have exactly the information before that. Maybe next when I'll charge my phone again up to 100%.
Hello, me again :)
Today I charged my phone up to 92% and two hours later (no used) the battery is at 75%. it is normal?.
What apps have you allowed unrestricted use of battery?
Please also post back what you have enabled under: Settings - Battery - Power Master - Auto Start Manager
Recently and donwloaded app no check, preloaded:
No apps in Downloaded section?
Yes but only whatsApp is enable
That is odd. Did this issue occur from the last time you posted? 15th.
Also, can you show a screenshot from Amoury Crate too?
I would give battery calibration a try - please see below page for instructions:
It does seems like I have a similar problem, "Screen" take more than usual. I will try the calibration but I doubt it will work.
Worked fine after the update but some time after it decided to drain real fast through Screen instead of Android System
The other thing I can think off is the fingerprint reader - but that's if you use it.
Go to settings - security & lock screen - Fingerprint - enter your pin - press on where it says "Unlock device" (not the enable/disabled button).
Here you should see "Unlock device when screen is off" - what I have here is (tricky as well as it could be a bug):
The only thing you should have ticked is "Tap screen to show indicator" and the "On" at the top of screen.
Alright, I've done this, does it should look like this? Also I should be able to try the calibration soon
Yep , that's what mine looks like.
Use this for the time being to see if it helps and then you can do calibration after since it will take longer to do.
Try restarting device and fully draining the battery to 0% until it turns itself off. After that charge it to 100% while off. Its the easiest way to calibrate a battery or troubleshoot any issues related to battery. Let us know if this fixed your issue.
