Standby drain

[tel033]

I'm experiencing this too .my battery life was fine till 2 days ago,don't know what change but in a day android system and os and idle are consuking around 300mAh EACH
Could it be the knox ,I just configure it some days ago
Also gsam doesn't let me see under app usage detailed info ,is that normal?

Did you enable it with adb commands with a pc? If not, in the app itself there is detailed instructions foe doing it

Getting horrible battery drian this is with everything turned off including AOD, mobile reception is full bars

Don't know what you have installed but the app in your notification bar - such app with real-time monitoring - usually consume a lot of battery.

It only monitors the internet download/upload speed only runs when mobile data/wifi is on, barely has any battery impact as ive tried uninstalling it. it was the FB app that made the high drain. I am not getting 1-2% loss in 8hrs.

Can anyone explain to me why Google services would be using sensor all the time? Significant motion sensor is on for many hours but I can't figure out how to reduce this. I don't have any of the fancy things set up like smart view or other things but I do have the retina unlocker.

Not sure why the Pic didn't post

The standby time is so good on this phone. Very impressed.

That doesn't look like a Note, unless you've replaced your ROM.

All of a sudden, for no apparent reason, standby times have become horrendous and idle battery drain goes haywire. No new apps, no updates, nothing.

Does anyone else feel that this happens to them on basically every Android phone they've ever had?

I don't really see the point of buying a smartphone and shutting off all the 'smart' things for the sake of not plugging in.

For me, I don't charge overnight as lithium-polymer batteries prefer to stay outside of the upper SOC. My phone sits by my beside, with wifi-on and AOD. I usually go to bed with about 40% and wake to about 30%.

30 minutes on the charger at that point gets it to a useful 80% and that usually is done on my commute. I may also put the phone on the charger occasionally throughout the day (1 more 30 minutes session) so I can leave work with it at about 80% charge.

So, I charge just about 1 hour per day and my phone battery never reaches 4.35v. I'll likely have a strong battery still 2 years later with this charge profile. Samsung already claims 95% capacity with normal charging and use patterns. My phone has a great chance of meeting those claims.

What's the point of having 95% capacity in 2 years time if you're only ever charging it to 80%?

Might as well charge to 100 and have 95% 2 years down the track.

It's a Note8 with stock ROM. Using Substratum and a custom font.

It's not that I NEVER charge to 100%. That would be an incorrect assumption. In my REGULAR charging, I don't exceed those amounts, because I usually don't need it. But I certainly have put the phone up to 100%.

Really, what I am avoiding is leaving the phone charged to upper SOCs for extended periods of time. My phone doesn't need to sit at 100% for 6 hours every night and making it do so would be detrimental to the battery's life.

Same here. With sealed batteries, I do the same. Unlike my Mrs she leaves her note 8 on wireless charger over night cooking. Tut Tut. Personally, I don't use wireless and is slow cable charge up to around 80% on average.

Are you sure you have your facts right?
As far as I know these batteries like to be full or at least near full. And not be drained down to say less than even 30-40%

Standby drain is 2% per hour, and that is really disturbing!

Yes! I have my facts right.

Being an ebike builder, I'm a lithium battery enthusiast. We study these things closely. Before I became an ebike guy, I just charged my phone overnight like everyone else. After caring for thousands of times the amount of li-poly batts in phone, I have a decent understanding of what is detrimental to the life of a battery.

I look at it like a rubber band: It doesn't want to be stretched to it's limits and definitely doesn't want to be held there overnight.

I think you're overreacting. It's not even close to detrimental.
Other things can be detrimental. This is more like slightly better if avoided.

these batteries don't like being full or empty. 40-70% is most ideal. being empty is most damaging.

I have the European (Exynos)dual sim version of the note 8 and since the last update a week ago,with November security patch the stand by battery life sucks. 2 to 4 % hour doing nothing I don’t get many notifications or anything. I have hard reset it and all and nothing seems to solve it. The phone also get much warmer using it . I think Samsung screwed up something

Damn it!

 

[note3userr]

The battery charge is only an issue if you're planning to keep the phone for years. Charging to 100% and draining to 1 will have no big effect in a year or 2. But I still don't condone charging overnight . I usually charge mine to 100 before sleep

So how comes so many folks with Note 5 devices needed battery replacement after 2 years ?

I believe if you want the battery to last longer than 2 years then use the 80-40% method .

I had a note 5 and didn't need a battery replacement. There is many factors that go into a batteries life other than charging it fully. I have owned Android's since the very first Nexus and always charged to 100 and never had an issue. Only using such a small window of your battery is such an annoyance that the benefits of it cancel out.
