Default galaxy note 8 battery life help

so i have a galaxy note 8 and i have had it for 6 months now and the battery life is just awful i can only usually get 1hour screen time and its already down to 60-70 percent.

i have done every single battery saving trick in the god damn books, i have battery saving on, brightness down, no haptic feedback sound, no motion controls, no sync, no auto updates, no gps, the only thing on my quick toggles are wifi and power saving and rotation on.
i have used juice defender
i have rooted and used titanium backup to debloat everything!

Maybe your charging problem
When charging , you must power off until 100%
And maybe your charger cable have problem .
And also you try this kernel

I'm new here since I bought the device yesterday, but this looks like a general issue...

This thread explains battery saving, some issues that might be related to your case are:
- If you misuse Greenify or any other "battery saving" apps they can actually lead to battery drain
- @gafri1: If "When charging , you must power off until 100%" means that every time you charge you must do it until 100% then it's false. Lithium ion batteries DO NOT have "memory", so charging to 100% or 70% doesn't make any difference. There's this thread that contains a brief explanation and this entire website dedicated to batteries.


As far as your specific problem is concerned, what do your battery stats say?

Better Battery Stats and Wakelock Detector can be used to collect more complete battery stats. They DO NOT SAVE BATTERY, they just tell you what might be draining it. The first step should be to check the built in battery stats in the Settings and then turn to other more sophisticated tools.

Default Charging issues

OK, had a few instances of odd charging that may be what is happening.

One OEM cable got pinched at the head of the micro USB. Shorting and bad connection. Battery shows charging, but never increasing charge.

Ended up melting the head and heating up the tablet.

Long aftermarket charging cable or extension cord. Some do not have proper pin out... will not charge or show charge. End up having little charge after disconnecting from charger.

I watched, a tablet go from 100% to 90% within 2 minutes and slowly decrease the rate until it leveled at 60%. A false reading of charge state until battery data caught up with battery's true charge.

WiFi only, or connected to cell network? This is a very important detail, since if its on the cell network, the reception in your area can have a HUGE effect on battery drain. In fact, when talking about smartphones, I'd say cell reception is the primary factor behind battery life.

In any case, the battery drain you mention (30-40% drain with 1 hour screen on time) is not awful, although not great either. Especially depending on what you are doing during that screen on time (gaming can be a huge drain, streaming video too, but usually less so). I get maybe 5 hours screen on time if I'm watching Netflix. That with no battery saving, WiFi only Note 8.

Also, make sure Smart Stay is turned off, as it seemed to me to be a big battery drain (and never really worked all that well for me, anyway).

Agree with both these points. I've seen these "battery saver" types of apps (Juice Defender in particular) which have caused more issues than they solve. Some folks will swear by them. But don't take for granted they will increase your battery, and use them wisely. Don't "misuse" them as you say.

And charging while the phone is powered off is a myth that has been debunked long ago. Aside from the fact that the device will charge slightly faster (it won't be draining as its charging) this will have no effect on battery life.
