[OnePlus 6 Real Life Review] Gugus38:
Over several weeks on different Open Betas with xXx, tried stock as well as almost every kernel (EX, bluespark, Radioactive, smurf) for several days each, and get an average idle drain of 0.9%/h.

Custom kernels had negligible effect, or it would drop to 0.3% overnight, but would go back up to 0.8-0.9 on average after a few days, absolutely not worth the trouble of installing... they cause more problems than they solve.

So I stay on stock kernel with 0.89%/h idle drain. Overnight with airplane and battery saver i get 1-2% drop, perfect for me :)
[OnePlus 6 Real Life Review] Macusercom:
I don't fully understand. You get 0.9%/h on custom ROMs but almost the same on stock OOS?

Also why does it drop 1 to 2%/h overnight with 1% per hour. I am not getting it :eek::confused:

---------- Post added at 08:31 PM ---------- Previous post was at 08:29 PM ----------

Mostly Wi-Fi or also mobile data usage?
[OnePlus 6 Real Life Review] Gugus38:
Only on oos open betas, and overnight as I mentioned it's with airplane mode and battery saver :)
[OnePlus 6 Real Life Review] xxxSilverxxx:
Mostly mobile data.

rooted stock rom battery draining 14% in 8 hour standby with wifi and data off. Whatsapp, FB, Messenger forced stop before I go to bed. 14% is normal battery drain?
[OnePlus 6 Real Life Review] whizeguy:
No. It's like 10% too much
[OnePlus 6 Real Life Review] sinkoo1979:
any suggestions on custom roms that won't drain so much juice?
[OnePlus 6 Real Life Review] whizeguy:
Stock oos doesn't consume that much. I loose 2-3%

Treskmod is really good... Snappy and fast, performance it's the best I've used this far. I loose about 3-4% on it. But really, it won't matter if you have apps that constantly update all night
[OnePlus 6 Real Life Review] Totone56:
Tried almost every kernel, with OOS, TreskMod, Omni.

Full stock OOS 9.0.3 with stock kernel gives me amazing results, the best combination i had.

Around 3% lost in 9h of sleep (So around 0.3%/h), with LTE, Wifi, no particular battery saving tweak or app. Multiple social apps installed (FB, Messenger, Instagram, Snapchat, Twitter), no delays in notifications or background restrictions, "Advanced Optimization" disabled as it causes issues during sleep.
[OnePlus 6 Real Life Review] b4bass:
I get usually around 0.4% battery drain on stock stable OOS with FK kernel and a few tweak (like 25% downclock on gpu and CPU + nap time)

I have all major social network + chat apps. Also I use Facebook lite.

I usually on Wi-Fi.

Phone is snappy and ilde is quite low
[OnePlus 6 Real Life Review] FiloSvR:
I reduced my huge battery drain closing all the background app every time i want to lock the display. Without doing that i consume, in idle, around 3.4%. Closing the app around 0.4%.

I'm using all the aggressive background restrictions, but apps like tinder, clash royale, facebook etc. drain my phone anyway.

Does anyone find a solution for this?
[OnePlus 6 Real Life Review] Mord0rr:
2% or 3%...only GSM on...

Depends on dignal strenght, apps running on....for me is the normal value.
[OnePlus 6 Real Life Review] Mord0rr:
And 4% tonight with PIE 9.0.3.....i left with wi-fi off and data, 64% and at morning it was at 59%...

Not good....
[OnePlus 6 Real Life Review] meilbox:
Yeah....

Stop using tinder :)
[OnePlus 6 Real Life Review] FiloSvR:
Ahahah impossible, the other way to get la*d is waaay to expensive :laugh:
[OnePlus 6 Real Life Review] AndroidBolder:
LineageOS with the wireguard kernel module and microG standby drain is around 10% per night, much more than stock :/
[OnePlus 6 Real Life Review] jaber_jb:
Usually sleeps for 6-7hours. And battery drain while sleeping is 5-6%.
[OnePlus 6 Real Life Review] KJYap:
3-4% drain for 8 hours of idle. F2fs oos, arter kernel
[OnePlus 6 Real Life Review] Totone56:
Stock 9.0.3, with Smurf Kernel, no other mods.

Amazing battery life, with Spotify a few hours a day casting on Google Home, Facebook, ect, and WiFi + LTE enabled at night. Battery saver just turned on when reaching 25%, didn't use is otherwise.

Around 0.3% per hour when the phone is idle.

Charged Friday at 11pm, plugged Sunday evening at 10pm :laugh:
[OnePlus 6 Real Life Review] echo246:
I know it's a bit late to respond but I recommend buying FK manager and installing francokernel. I get 1.34% idle drain at best plus 5-6hrs SoT using apps like Snapchat with custom profiles. I definitely recommend you to buy it :).
[OnePlus 6 Real Life Review] ebady:
2 days continues on one charge

I don't root my phone or anything, but I running android Oreo with greeny and stock OOS. [IMG="battery life"]https://ibb.co/jkxkzL0[/IMG]
[OnePlus 6 Real Life Review] fuzmik:
Went back to Oreo 5.1.11 on xxx v5 stock kernel on 0.1% battery drain when I went to sleep.

But on pie, I'll get 6-7% battery drain on custom kernels.
[OnePlus 6 Real Life Review] Be4st187:
Damn, and I thought my 0.3% per hour was good on pie with MicroG
[OnePlus 6 Real Life Review] jimger:
Anyone on 10?
[OnePlus 6 Real Life Review] LuthorKid:
I am.
[OnePlus 6 Real Life Review] jimger:
Are u happy with the standby drain? Generally I am quite unhappy with battery performance on 9 and 10 of Oneplus 6. I think I haven't stayed much on Oreo though
[OnePlus 6 Real Life Review] LuthorKid:
Not really. Just with fairly use, it can last me almost a day but with heavy use, it's a drag between 3 to nearly 4 hrs. That's with WiFi connectivity. Network conectivity is of its own a different experience.
[OnePlus 6 Real Life Review] jimger:
Yeah I do have 4g sim and 2g on the 2nd sim and it certainly needs to charge it over the day with medium use. Haven't activated battery saver or anything, but during trip if I didn't have the power bank it wouldn't make it for over 1/3 of the day....

Let's see what the new stable versions will bring. At least before it was bug free... Now I have random reboots or screens remaining turned off
[OnePlus 6 Real Life Review] LeKeiser:
I don't have 2 SIM cards, so I might be wrong saying it doesn't matter if you have one or two SIMS in your phone. What drains the battery is a bad DATA reception. Mine is not that good at home and not good at all at work. I can see the battery going down faster there. The drain is not that bad when I'm outside.

So if you have 2 SIMs installed, then it's logical that the drain is double what others have.
[OnePlus 6 Real Life Review] Cst79:
Please note, I do NOT turn off syncing (to me phone, data and syncing are fundamental to a smartphone, turning these off means turning it into a useless toy), any application can sync at will, I only restrict sync for some Google features that I don't need. Google is really data hungry and careless about how it uses the battery as long as your data reaches their servers. And my phone loses around 1.5% per hour every night, which is not a low usage. But not the usage during the night is the one needing optimization :)

About the RAM, more chips means more power usage, it's simple. If the 6GB has one less DRAM chip, make sure it draws less power. DRAM needs constant refresh (unlike the permanent storage), and refreshing an extra 2GB is not free.

Here is what Apple said about putting 32GB of RAM in their MacBooks, for example:

https://www.macrumors.com/2016/10/28/new-macbook-pros-no-32gb-ram-battery-life/
[OnePlus 6 Real Life Review] LeKeiser:
A bad DATA reception really drains the battery. So with 2 SIM cards installed, you can double the drain. Like I said, I lose about 4% battery over night, WIFI off, only DATA on. But my reception suxx in my bedroom, so...

About the RAM, we're talking about 2GB difference and trust me, this is not what's gonna drain your battery. If we were talking about >100GB I would say "it might" but 2GB is so little that no, it doesn't matter.
[OnePlus 6 Real Life Review] piotrkruczek:
Dual sim drains battery - that's for sure, but I wouldnt say it doubles. I miss the special options from resurrection Rom from other devices, where i could pick one sim on constant LTE and the second one (only for calls) on 2g. Reception was great and it seemed to use less power.

About the sync:

Most of my apps can refresh while Im opening them. Resyncing from time to time without the need is pointless for me, so I manually pick inbox, chrome and Calendar to sync. Everything else from Google stays without it.
[OnePlus 6 Real Life Review] Muntasir Mahmud Saif:
only 2% total? people losing 10% even I'm also
[OnePlus 6 Real Life Review] randomA:
Been reading this thread for some really interesting tip.

I have a few questions, I hope you can help with:

1. How do you turn locations Off for everything and just let some apps have it On?

Or do you just disable location one by one in apps until 2 or 3 are left on?

2. I have 2 SIMs plugged in, but the phone says that only 1 is active , the other says "no SIM". What gives?

3. How do you only restrict sync for some Google features ?

3b. How to block usage access for Google Play, Google etc ?

3c. How to disable all syncing except "Gmail" and maybe "Contacts" for Google Drive, Google Photos etc?

Thanks a lot!
[OnePlus 6 Real Life Review] Muntasir Mahmud Saif:
i lose only 2% whole day if i just keep it on galaxy note 8 and it's full of bloat .but oos is stock but why it's losing 10% overnight? it's wierd and concerning..
[OnePlus 6 Real Life Review] Cst79:
1. Settings->Apps->Application List->[see which one has location access and remove it]

3. Settings->Accounts->Google->[click on each Google account to set what to sync and what not to]

3b. Settings->Security & Lock Screen -> Apps with Usage Access (disable the OnePlus Switch at least)

3c. See 3
[OnePlus 6 Real Life Review] randomA:
Thank you, appreciate that.

What is the Oneplus switch anyway ?

Also yea, according to the official OP forums, there seems to be something messing up with overnight battery drain: https://forums.oneplus.com/threads/...ot-how-to-improve-battery-life.837232/page-63

Nobody has found a solution so far besides putting the phone in airplane mode.
[OnePlus 6 Real Life Review] Xebeck:
.

.

What do you mean by charge/discharge cycles...

I thought we aren't supposed to drain batteries to 0% now days?

Cheers
[OnePlus 6 Real Life Review] masi0:
its all how you setup your phone, which apps you allow to work in background (like FB), choosing which one are supposed to allow push notification, disable wifi/bt scanning, etc.

its not rocket science really
[OnePlus 6 Real Life Review] Muntasir Mahmud Saif:
i also did that and still losing ****ing 10% overnight... it's so annoying... tried Greenify stopped all process and still this ****
[OnePlus 6 Real Life Review] piotrkruczek:
1. Open settings and Type in search box "Pemissions" and look for app pemissions.

2. Do you have the second one activated? Check SIM options in settings. In OnePlus 6 you have a toggle to activate sim.

3. Settings > accounts > Google > manualy switch off the ones you prefer.

4. Type usage access in settings and look for Google Play. You might want to take a look at other apps as well.

5. Same as point 3.
[OnePlus 6 Real Life Review] randomA:
seconding this Q

---------- Post added at 10:01 AM ---------- Previous post was at 09:57 AM ----------

in the settings, the sim 2 is blacked out and says "no sim".

pretty sure there's the sim in the sim2 slot inside the phone....
[OnePlus 6 Real Life Review] piotrkruczek:
Maybe try with a different sim card just to double check if the current one is working properly.

You can try taking sim1 card out and leaving just one, thats not working and see what happens.

I don't have such problem so can't figure out, what might cause it.

Anyway good luck

[MENTION=1999961]about[/MENTION] the battery:

You should drain battery to zero once in a while to recalibrate. I do it once a 1,5 months. Other than that - you should stay between 30-80% most of the time to reduce battery wear.
[OnePlus 6 Real Life Review] LeKeiser:
I'm sorry, I should have been more explicit with my view of cycles and charge/discharge. I let my battery go as low as 20% and then I charge it up to 80% max. I've done that for quite a long time and my O+1 is still rocking :)
[OnePlus 6 Real Life Review] Cst79:
For those unhappy about overnight battery drain, did you try turning on the "Advanced battery optimization" ? (Settings->Battery->Battery Optimization->[click the three dots in upper right corner]->Advanced Battery Optimization) followed by setting to "Do not optimize" for apps requiring instant notifications from, like Whatsapp, Gmail, etc. ? It seems to have a "very positive" effect to my phone :)
[OnePlus 6 Real Life Review] randomA:
funny the google apps dont appear in that list
[OnePlus 6 Real Life Review] Cst79:
It's probably because Google forbids Android phone manufacturers to mess with their services background activity outside of the optimizations provided by stock Android.

---------- Post added at 01:13 PM ---------- Previous post was at 12:32 PM ----------

Here is one more interesting tip to help with overnight drain and battery drain in general:

- Turn on Developer Options (Go to Settings->About Phone->[Tap the "Build Number" 7 times])

- Go to Settings->Developer Options and turn on the following setting: "App WiFi Multi/Broadcasting Filter". It specifically states that turning it on prevents battery drain.

It seems people have quite a bit of success with this option regarding overnight battery drain:

[OnePlus 6 Real Life Review] chrisjcks:
I brought this up on the OnePlus forum,

and within a day, a moderator closed my thread!

I stated a got great battery life on my OnePlus 6 in a previous thread, so apparently reporting my 'Airplane Mode Battery Drain over night was the exact same thing & contradictory

One is daily battery use, One is battery drain in airplane mode - 2 totally different things.

last night i lost 7% in Airplane mode! - 5hrs.

I have wifi/bluetooth scanning already disabled & definitely no FB or anything like that.

I will try the developer option above. :good:
[OnePlus 6 Real Life Review] vibrantliker:
Not clear on this. What apps are recommended to not optimize?
[OnePlus 6 Real Life Review] Cst79:
For each user it depends on what apps you need instant, real time notifications from. From the optimized apps the notifications may come out delayed.
[OnePlus 6 Real Life Review] vibrantliker:
Which saves battery, optimized or not optimized?

Also, what about this setting(image)? Seems that turned on should also save battery?
[OnePlus 6 Real Life Review] Cst79:
Optimized apps save battery.

And yes, like I said, that option (which is just another name for Aggressive Doze) should help save battery.
[OnePlus 6 Real Life Review] iElvis:
I turned it on and noticed a difference.
[OnePlus 6 Real Life Review] Septfox:
Anything that you need to keep running in the background or receive timely pushes from. E.g. Google Maps (for navigation, though they might have fixed it)/Waze/etc, non-SMS messaging services, non-GMS mail clients, games you want to keep an eye on, things like that.

-----

To clarify what you guys are messing with, Advanced Battery Optimization is part of (or maybe renamed) Doze, and might actually be "official" Aggressive Doze (as Greenify calls it). Doze forces apps to stop processing and communicating so much in the background outside of defined intervals.

Doze was enabled by default after implemented in Marshmallow, but it took a *long* time for devices to actually enter it because the device has to 1) be screen-off and 2) be completely stationary for a while; no input from the orientation/gyro/etc sensors. I assume that it's been improved for AOSP Nougat and Oreo, since the Marshmallow default implementation was 95% worthless for day-to-day usage, and OnePlus has probably fiddled with the settings themselves. Heck, rooted users can change the settings themselves, if they want.

Aggressive Doze forces Doze very soon after screen-off and (optionally) ignores sensor inputs, but unless you whitelist apps ("Not Battery Optimized") they're forced to comply and limit their activity for however long has been set.

TL;DR

Advanced Battery Optimization is probably Aggressive Doze

Battery Optimized: apps are limited in their background activity to intervals of whatever OnePlus has deemed sufficient, could be up to an hour but probably far less

Not Battery Optimized: apps can do whatever they like, basically default behavior in Marshmallow and earlier
[OnePlus 6 Real Life Review] randomA:
After enabling the various tips that were posted in this thread for maximizing preserving battery life, I can confirm that during last night the phone still dropped a whole 5% in total standby.

Is this acceptable?

Really the only thing that I can thing of is the red LED light blinking to notify the battery is low: does that even affect battery so much?
[OnePlus 6 Real Life Review] LeKeiser:
A LED drains nothing. Was your phone set in airplane mode during the night?
[OnePlus 6 Real Life Review] randomA:
no
[OnePlus 6 Real Life Review] LeKeiser:
then the drain is normal. I guess the DATA is still active, maybe we WiFi as well, so...
[OnePlus 6 Real Life Review] randomA:
so youre saying 5% drain overnight is normal?
[OnePlus 6 Real Life Review] LeKeiser:
yep

It's not because you're not using your phone that it's doing nothing. It's still receiving data through your SIM card and/or the WiFi and/or through your BT connection. If you have a bad DATA reception then the drain might even be worse.

If you want to check your drain during the night, activate the airplane mode. You'll still lose some %% but less than 5 I'd say :)
[OnePlus 6 Real Life Review] siddarthsmallya:
With 1 sim, data off, no wifi, alarm on - 3% over 8 hours. Same every day, very consistent
[OnePlus 6 Real Life Review] LeKeiser:
3% is "normal"

otherwise, turn off the phone :)
[OnePlus 6 Real Life Review] tdssmarty16:
My battery drained 25-30% overnight today and the battery graph shows a constant decline which means the phone did not go to sleep at all

Battery drain ivernight was amazing in oos 5.1.0

Things have gotten worse only after updating to oos 5.1.5

Is there any way to stop this overnight drain

Also i am coming from a xiaomi device and that drained a maximum of 2% overnight

Oneplus should really optimize the overnight drain
[OnePlus 6 Real Life Review] LeKeiser:
Please, have you done a wipe cache after the update?
[OnePlus 6 Real Life Review] Xebeck:
.

Do understand that there are no ideal machines...

Only real ones.

2-3 % over 6-8hours is normal if you've got your Mobile data and WiFi turned off.
[OnePlus 6 Real Life Review] b.huss2:
I also had a problem with unusually high screen off battery drain. I really think it all depends on how you setup your phone, what apps you install, what services you allow, etc. It's why everyone has different results. However, it's fixable without turning off your services like mobile data and location or ambient display or whatever. This is a phone so all of those things should be on to function properly. I'm not about to start turning off my services every night to accommodate something that shouldn't be a problem in the first place. So, I installed "better battery stats" and patiently went to work fixing partial wakelock problems. Now I usually plug my phone in at night...I mean that's what makes sense because it's not in use. However I've been getting very good reports on battery lately so I left it unplugged to see if anything was keeping it awake at all and......nothing.....deep sleep the whole night.....very little battery drain.....mission accomplished (with all services running as I like). It just took a little patience and maybe some research when certain issues rise to the top of the list.

Now I must add that I am on WiFi and get decent mobile service where I am. I understand that poor mobile services could make a difference with some so as usual, ymmv.
[OnePlus 6 Real Life Review] gothy.gothy:
And how did you block those wakelocks on an unrouted phone?
[OnePlus 6 Real Life Review] b.huss2:
What makes you think I'm not rooted?

I didn't have to block anything. first major partial wakelock was coming from samsung health. I just uninstalled that because I really don't need it. I initially installed it when I was setting up my watch without really thinking about it. The second major partial wakelock had something to do with location services. Something there just gets hung up sometimes. I just went into google settings and turned it off, then turned it back on and no more wakelock.

You were right by-the-way, I'm not rooted. I was, prior to all of this, until I decided I had no reason to be, so I reverted back.
[OnePlus 6 Real Life Review] Eric214:
letting a battery drain isn't a thing anymore with Lithium-Ion batteries. That was a thing for batteries from the 90's Ni-Cad (Nickle Cadium) batteries that developed a memory. With Ni-Cads if you always charged them at 50% they would start to show a fully depleted battery in the time it should be only 50%. Lithium-Ion batteries have no such memory issues and the further you let them discharge (Depth of Discharge is what it's called) the less charge cycles you will have long term. Meaning the battery capacity will start declining at a much year time.

I can use my OP6 all day for work (about 3-4 hours of SOT) and still get home with about 60-70% battery. That's with 30 emails with replies, hour or so of calls, whatsapp, texts, YouTube, web browsing but will charge my phone at over 50% to save the battery long term capacity. there are days I charge my phone at night when it's still over 70%. Depth of Discharge directly relates to the number of total charge cycles a battery will have life time. charging at under 25% regularly will give a battery 250-350 cycles, around 50% 500 or so cycles, and 75% or more 800-900 cycles. This is before diminished capacity becomes apparent. .
[OnePlus 6 Real Life Review] Xebeck:
.

If you mind me asking, but how do you know this?

---------- Post added at 04:35 AM ---------- Previous post was at 04:33 AM ----------

My battery drain at night is under 4% in about 7.5 to 8 hours with WiFi and Mobile data turned off.

It's good for me.
[OnePlus 6 Real Life Review] Eric214:
The battery type and the memory thing I've known for years. And how lithium-ion works and the charge cycles thing is from battery University.

http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries
[OnePlus 6 Real Life Review] Xebeck:
Thanks
[OnePlus 6 Real Life Review] Cst79:
I think you are really missing the point here. The point is not to increase the number of cycles, but to make your battery last a longer period of time.

Charging a battery when it is still at a high percentage questionably increases the number of charging cycles, but you also need to charge way more often !

I prefer to let the battery drain and charge it as rarely as possible, once every two days or even longer period between charges. This way, at the one year mark I have charged my battery 180 times while you will have charged yours 360 times. Which way is better ? It's a no-brainer :)
[OnePlus 6 Real Life Review] Xebeck:
Nope...

Those mini cycles do not count
