Maybe i missed something. But my battery drains more quickly on my Samsung note 10+ with /e/OS than with stock with the same number of installed applications and the the same intensity of use.
I noticed the same behaviour in the past on another Samsung with Lineageos.
Did I miss something? Is there anything I can do to be able to use my phone at least 10 hours without charging ?
Splendid offer. I suggest a first measure is to go to Settings > Battery > Battery usage.
This comment may depend on your device and charging cycle: select a relevant part of “recorded time”
Battery usage can be
Viewed by apps – where usage is expected very close to your imagined use.
Viewed by systems – where usage is expected to mirror the above.
From the systems view I find it quite unusual to have system apps using more than 1% without good reason. One could compare screenshots which might validate or contradict this comment.
Just a word … Systems → CPU is higher than Screen. Not a problem but may say something about the use of your phone. Comparison with App usage might show you using high CPU demand apps, thus this 40% might mirror usage and / or the phone has an efficient screen.
Where I said system apps are not usually high … I really meant software (say like e-Drive or Mobile network) rather than hardware. The hardware will naturally use power, but battery drain will quite likely be due to software “waste of power”.
