Note 8 Ultra poor battery life

[dragonwarrior105]

I purchased note 8 Dec 2017, very poor battery life. Lost all power in Feb and wouldn't recharge. Contacted samsung was told to take to their auth. Repair center. 3 days later was advised tried 2 diff batteries they could get it to boot up but wouldn't recharge. Checked charging ports no problem. Was to to call Samsung. They'd advised me to send in. 6 weeks later after 2 calls to them for status. I'm told not covered under warranty liquid damage. The phone has never gotten wet. The repair facility checked for water damage prior to replacing battery. I even called and talked to supv. And stated to them it's never been near water and kept in a case. I then questioned how can the advertise the phone to be water resistant and withstand being submerged in 5 ft of water for 30 min and not get damaged. They had no comment. I filed with states at and then someone from samsung presidents office emailed that liquid damage not covered. I replied and got a message to call back. I called number 4 different times and still no call back. So I say buy apple or other carrier. Samsung will find excuse to decline warranty coverage

My multi year experience with Samsung is sometimes you get a bad phone due to hardware, software glitches, bad battery. My four Note 5's, three stunk to high heaven... the fourth was a charm, direct from Sammy repair with NEW and tested battery. This Note 8 From Sept has been absolutely stellar.Battery life excellent. NO social media, strong LTE and Wifi signals, cache partition clears. Battery is slowly degrading due to high usage and thanks to quick charge, this phone rocks

Yes. No difference in battery life.

can you check device maintenance,Battery,Battery Usage and see which app uses the most power?

For those that are on the fence with doing a full factory reset or not, this may help. A few months after updating to Oreo my battery life became terrible, mainly standby drain. After trying all the usual cache wipe, app settings, location settings, etc...including a complete wipe and restore from backup, there was little to no improvement. Two weeks ago I bit the bullet and did a complete wipe and manual install of all apps, files etc... Phone is back to working flawlessly with battery life just like it was new. Hope this may help someone.

Turn off/ Disable everything related to Bixby. It was not showing up under battery usage but if you go to Settings, Apps and look at the Bixby Apps my usage was 25% since last charge up. Disable it. Bixby sucks the fat one.

Complete wipe after Oreo sorted out my battery problems. Looks like new now. by the end of day I still need 40%. Good!

Has anyone noticed that all the screenshots of good battery life are on black background screens and the bad ones on the default white (maximum screen drain) background?

Things that drain battery:

• Constant polling of social media
• Bright screen backgrounds (black uses much less)
• Video and gaming
• Using on full screen brightness

Pick the social media apps you must have updates from and set the others to only update when you open them.

Even on high brightness and res the screen will use much less power if the background is black.

High res screens don't drain battery significantly more for home screens and internet but will for video and gaming.

I have max res set so I can usilise VR when needed without resizing screens and icons. I have all black themes set and have a 40/55/100 toggle set on brightness. 40% for home, 55 for public environments where I want to show the screen and 100 for outside or when 55 is not enough.

I run no social media apps on the phone. I check them via site during down time. I have no need to know that Joe got up late and had shreddies for breakfast while in a meeting at 10am.

Direct messages can be handled via other services such as IFTTT. A single push service rather than multiple polling apps using power and bandwidth.

Saying all that, the Note 8, and Android 7 handles power pretty well. Excessive battery drain is almost certainly due to excessive app misuse.

Pretty certain I'd get a day's worth of music, Words WF, Draw Something, Browsing and misc even without the precautions.
