[Q] Best Battery Life Setup

Just wondering regarding data connections.
What setting is likely to give the best overall battery life. WiFi set to never sleep or WiFi set to sleep when screen is off
I'm not sure what would use more power. WiFi or 3G

Calibrating battery(free in market) is the best for you battery, full charge til mv=4182(or higher if you get it), then use the phone til it`s completely empty and shots it self off. Then your up to go. You can use Hp power packs as well with hp kernel.

I've gone back to using HP SR2 and battery life is great. But wifi and Bluetooth doesn't work properly with this kernel

[Q] Wi-fi and Battery relation

Hey guys I got a question;
My wi-fi router seems to be broken, wi-fi signal drops too often (not just on my one, it also happens on my nexus 7 and one s so I think it is broken). My question is; does that make battery drain faster? I mean phone is constantly having on and off wi-fi.

Does the whole network get no data incoming, or are you connected to a WiFi that drops it's connections but still broadcasting it's SSID?

I loss incoming data completely. It happens to often, I mean maybe 6-7 times in a minute. And I noticed my phone's battery draining too fast even without me making a call or using an app or anything. So I suspected if that broken wi-fi causing it. If it is not my battery might have some problem too, which I hope not.

WiFi shouldn't drain any more than usual if incoming data is lost as long as you remain connected to the WiFi. I might be wrong though. Install GSAM Battery Monitor and see what's draining your battery the most. If you need a more detailed one, try Better Battery Stats (it's free for XDA users, it's in the App forum )

I can't find it.
And the thing is im not connected to wi-fi all the time, that's the problem. Maybe dropping off and connecting back all the time causes battery to drop low faster than usual, that's what I'm wondering.

As long as you can see the WiFI logo on your phone it shouldn't matter whether there is a connection or not for battery drain.

Then yes it will drain. Your router is dropping the network as well as the connection, so that will drain a lot of battery cos the phone is constantly scanning for available networks when your router is down.

Battery drain on Android 6 Marshmallow when IDLE

I've found several threads about drain, but all of them are Android 5 related.
Unfortunately I still have this problem on Marshmallow.
I don't notice it when using the phone, but while idle, it drains battery. Attaching the screenshot indicating I charged my phone at around 10 pm and at 1 pm next day it was already at 15%. Screen on time was only 2 hours.
Wakelock Detector does not work on Marshmallow. Installed BetterBattery Stats to try to find out what's causing this, but If any body's experienced it and has any idea what should I do, please share your opinion.
I've got MRA58R, bootloader unlocked, rooted, root aps list is: call recorder, adaway, betterbattery stats, es file explorer, gmd gesture control, nexus 6 double tap to wake.
Don't know if any of this is really important, but still. The rest is pure stock installed with full wipe.
PROBLEM SOLVED:
Nexus 6 on Android 6 has bug with 5 Ghz WiFi networks, use 2.4 Ghz and your battery will be fine!

Today before going to sleep I charged the phone to 100%.
I left it with wifi on for the night. In the morning after 8 hours I had 65% left. Screen on time was only 42 mins.
Attaching screens from battery and better battery stats.
What should I do next?
I would appreciate any opinion.
I wanted to try turning off Google Now (it helped my friend on Nexus 4), but on Nexus 6 I just can't find this ON\OFF switch of Google Now, how to turn it off?

I'm running pure nexus and get none of that. Around 6 hours sot. I'm not sure what would cause this, have not seen it

i bet, 99.999%, that its your wifi. try leaving it off your wifi then check idle drain. my work wifi does the same thing, so i rarely use it.

This. I had a similar issue a while back (although it didn't happen every time). One thing someone told me was to avoid the 5g band on wifi. Whoever it was correctly determined that I was connected to the 5g band of wifi at home and suggested I use it on the 2.4 instead. I did so and my drain dropped significantly. Now if I charge to full, leave it on my nightstand overnight off charge, I wake up 6 or 7 hours later and lose *maybe* 1% per hour. That's with wifi, bluetooth, gps all on etc.

I will turn off WiFi now and give it a try! Thank you guys!
I will then test 2.4Ghz WiFi to see if it's really only 5Ghz WiFi that's causing the problems

I'll keep my fingers crossed for you that this fixes the issue. Additionally I should have noted, the person who suggested I use the 2.4 band instead of the 5 specifically noted that there is a documented "bug" where 5g wifi bands cause significant drain. That's apparently the reason that 5g specifically tends to be the culprit.

I have a similar problem as well. I have had wifi turned off all day today and its at the top of the list on battery usage. I have looked at every possible wifi option and turned it off. I dont understand what could be causing this. Im only bootloader unlocked, non-rooted, running stock image MRA58K

When you set it up did you set it to allow it to keep wifi scanning even when it is off for the location settings? I leave my wifi on 99% of the time and my battery life is great.

I dont remember if I did but I did turn that setting off when I was trying to diagnose the issue. I don't know if maybe it's a 6.0 bug that needs to be fixed. Good thing that being a nexus I hope it won't take too long.

I updated the firmware on my router and after doing thus none of my devices would enter power save mode on the 5ghz radio anymore and drain is now massive (check your router logs)
I tried flashing back to the prior firmware but still no go, so it must have been a driver update on the Quantanna radio as that's the only thing that was updated and it's a known issue with my particular model.

That helped me! Thank you guys! I connected to 2.4 Ghz and lost only 6% overnight!
I wish this information was easier to find, I'll update first post when I get home, it'll probably be useful to a lot of people.

It is a known issue with Quantenna radios on multiple routers; my ASUS RT-AC87 is one of them. Specifically as you said, on the 5GHz band. Switching to 2.4GHz wireless can fix this for the time being on Quantenna-based routers.
I've also had times where my battery seemed to have excessive drain if the cell signal dropped to non-existent; the N6 appears to drain fairly quickly searching for a signal. Unfortunately, AT&T occasionally drops in my house, and that's the carrier my work is on, so I have to live with it.

[Solved-Don't use 5Ghz Wifi]Having standby battery problems

So yeah I'm getting unusual battery drain during the night.
I disabled localisation, I have wifi on yeah but it shouldn't drain this much. Even my phone during the night with wifi+localisation on drains less than this , wth ?
Any idea what might be the culprit ? You can see on my battery graph I played something on the battery for like 45 min then when to sleep, and it decreased at a steady pace during that
https://goo.gl/photos/gvovhWsJZir9uPWJ8 , here's all the relevant photos. shows battery graph , tablet version and all the apps I have installed
Thanks in advance if anyone can help me solve this, because that's really annoying ;w;

Have you tried Doze ?
is it rooted ?
if so, you should have a look at this guide : [GUIDE][21/12]Extreme Battery Life Thread(Greenify+Amplify+Power Nap)✭ by v7
my 9.7 Tab S2 T815 has 0.1% to 0.5% per hour during nights

Haven't tried it no. But in the past I didn't need to. I also have an old galaxy tab 10.1 tablet and it only loses like 1-2% battery during the night. also with wifi constantly on
So why does this tablet drains so much during the night ? x.x Without being able to view wakelocks it's annoying, and I don't wanna root yet since it's still under warranty lol

Doze is good for non rooted devices, it only allow white listed apps to use network without disconnecting your device
---------- Post added at 01:58 PM ---------- Previous post was at 01:57 PM ----------
Mine is under waranty as well, but I rooted it the 1st day I got it, cant live without root ...

Well I'll check it out for next time then
I hope one day there will be a root method that doesn't trip KNOX :/ Would be nice

Tried out Doze for the whole day, and the problem still persists. Constant like 2-4% per hour battery drain when the screen is off ://
It's really annoying, is there any way to find out where it comes from while being unrooted ?

Hey there !
I have set wifi to off during stand by and also disabled bluetooth.
I noticed a huge improvement when I did this.

The culprit has been found !
Turns out using the 5Ghz Wifi of my house caused the drain. I connected to the 2.4Ghz wifi instead and no more drain during the night, complete flat line ^_^

I have an Asus router, and I'm using 5Ghz, and my standby battery drain is awful. I'll move to a 2.4Ghz band now to see if that helps.
Why did you ask about Asus routers? Is this a known issue?

With my AVM Fritzbox router, standby drain is perfectly fine when connected to 5GHz.

I don't know what the issue is, but I can confirm that 5Ghz was the source of my battery drain as well. Mine's an Asus and the OP said his was a B-box, so clearly this issue affects routers from multiple vendors.

Multiple Wifi issues.

For sometimes MI 5 battery was acting a bit weird time to time.
Clean flashing to LOS seemed to solve the battery issue, but I discovered another issue while checking up with ampere.
When wifi is on, battery drain is abnormally high. (-870 ma on average in ampere). Even in idle time, there can be 20-30% drain when the phone is virtually nothing. And in addition to that, the heating was a bit high too, with wifi on.
I tried everything I could to solve these. Tested different roms (Xiaomi.eu, LOS, RR, Paranoid), firmwares, tried wavelock blocking and all that.
Of course, I tested the battery drain on a fresh rom - and the issue persisted. So it's not some rouge 3rd party app, unless one of the Gapps is the culprit. But, of course, I even tried disabling some of the gapps like gp service and play store, just to be sure. Yes, the problem exists even with synch and location off, and those wifi scanning and other settings doesn't do anything either.
However, with wifi off, battery was quite good (-100 ma drain on average in ampere)
Recently the issue started escalating. Not only was there the abnormal high drain with wifi on, but toggling wifi crashed the device and started a reboot, after which the device connected.
The only major thing I had remaining to be done - is fastboot. I did even that. Fastbooted into official roms, older 6.0 Xiaomi.eu roms which worked fine in the past ....but the issue persisted. In fact it started to escalate further. More reboots when I try to switch on wifi. Sometimes got stuck in a reboot loop ...and so on.
Right now, wifi is not even connecting. It just stays at 'saved'. Oddly enough, enabling bluetooth and trying to reconnect seems to allow the connection to take place. The drain is still here. (The solutions in this thread: https://forum.xda-developers.com/mi-5/help/wifi-connectivity-problem-t3517777 isn't helping me either)
I don't think this is a router issue either. I did tweak router settings, channels, and all that. I rebooted it and all. No help. And, other devices are working fine with the same router. But, the most definitive evidence that it's not a router problem is that I faced the same issues when trying to connect (with wifi) to a hotspot created from a mobile network from another device.
Do you think it's the worst case scenario: a hardware malfunction?

Could you provide battery apps and hardware usage stats and graph?
My prediction it caused by Google location service that try to lock location but was unable to get GPS lock, so it tried to used WIFI scanning to get location lock.

I can provide the stats later. My device has been offline (normal condition) for quite a while...so there's not much stat to share as of now. I will collect and share them later.
However, I have checked them before. There wasn't anything too interesting. The graph very vividly showed how it fell only when wifi is on...but other than that, most battery was taken by device, idle state or something like that. I didn't find anything interesting in betterbatterystats either. Other than that I did checked the frequencies with kernel auditor too. It seemed normal overall. Though once, I did notice high spike in CPU usage. IIRC, the phone was in deep sleep for most of the time too. Not sure, what the current state is, because new issues are coming up now. So I have to recheck the condition.
I always keep wifi scanning, bluetooth scanning off anyway. So that's not the issue. 'I will again check in the china rom (no gapps), this time more rigorously,....that should clear gapps out of suspicion, if they are innocent.

Check the screenshot
In a freshly fastbooted MIUI global stable rom (with wifi scanning off, and wifi always on off), I got 1% battery drain (100% -> 99%) overnight (6 hours approx)
But, only in a few minutes battery went down to 91% when wifi was on.
The device was idle in both cases.
In past I have assured that it was in deep sleep. Similar rate drain in chinese rom (so no rouge Gapps), and same drain in custom roms.
The hardware usage was taken after I used the device for a while, which is why drain due to screen on is high. Anyway, even before using the device, the maximum drainage was attributed to 'idle phone' so there isn't really any interesting info. One thing to note, that the hardware battery drain states doesn't consider wifi to be the cause of high drain, however the drain is still clearly correlated with active wifi.
