Roll back to Nougat - Google Pixel Questions & Answers

Hey guys
Is there an easy way to roll back my stock device from Oreo to Nougat? My battery life with Oreo is terrible. like 1.5 hours SOT and 9 hours total life. I'm getting married this week and then immediately on honeymoon, and at the moment, my battery life isn't good enough to last the day, never mind be used as my camera and navigation whilst I'm travelling.
Any help would be much appreciated - I'm so out of the loop with the development community.
Cheers

Is it a Google bought or did it come from Verizon? If from Google it may be possible but I'm not sure of the steps. If it is from Big Red you are on O now and will need to wait for the fixes to be released.

Check to see if bootloader can be unlocked. If so, would have to download factory N image and flash through fastboot. I would also seek a second opinion just to be safe.

Nexus 5 is coming to me..i need some advice!

Hi guys!
In the next days the Nexus should be arrive also to me and i have a few doubts about the modding! Then i'm not new to Android modding...i have a LG Optimus 3D and i modded it in every possible ways (change bootloader or baseband, flash custom roms, root etc).
I read a lot of guides about Nexus 5's modding and i think that the modding is not hard!
However i want when i will put out the phone of his box i want only to turn on to see if it works fine and then if the battery is equal or above 60 % i want to unlock the bootloader as soon as i can and then recovery, root(with SuperSU.zip or with a stock rom pre rooted) and franco's kernel!
Then i know that flash things and also unlock bootloader can affect the battery percentage...however my main question is if i will make these things immediately after i put out of the box this can affect in some ways the battery's life? I mean...after the battery will discharge for the first time i need to put the phone on charging for 12 hours? (and then after this 12 hours i can mod my phone?)...i'm really confused about battery because i read a lot of things...someone told that with modern batteries the 12 hours is not necessary someone told that is necessary...
Thanks in advance!
There are a lot of different opinions about extending the life of your battery with proper charging habits (including the first charge)...I've read lots of conflicting information too. But honestly, I don't think it's worth stressing over. If you don't charge it "correctly" the first time, any long term reduction in battery life is going to be very minimal.
The average life span of phones these days is about 2 years for most people, and I doubt you would notice a significant difference within that time anyway (barring any defects). Batteries are built to last much longer than that.
My phone arrived with a 90% charge, so I proceeded to unlock, root, etc. right out of the box like just you're planning to, then charged it afterward (don't remember what percent it was at). No problems here, so you should be fine to do the same.

It won't mess the battery. When I got mine I unlocked the boot loader installed a custom recovery, and made a nandroid. Then I played with it on stock to make sure everything worked. I would recommend that
Thanks to all! Some time ago i bought an extended battery for my Optimus 3D by Mugen...and in the start guide they told the the first charge needed 12-14 Hours and then you can charge the battery every time you want! However i wish that my Nexus 5 will have a good percentage and i can unlock the bootloader, after i will put root or a rom stock prerooted and then the franco's kernel! I want to keep my phone stock because for other functions i will installa Xposed! Thanks for the help guys! Oh and if you have any other advice it will be appreciated!

Latest Software still causing battery drain?

I have read on various forums that the latest software update has been causing problematic battery drain on the M8 and more often the Verizon version. I briefly had one about a month ago but had to return it due to some contract issues. Now I am looking to get another as I really liked it. I did however notice that the battery did drain pretty fast when I had mine. It had the latest 4.4.2 software on it. If I root it, can I install an older ROM and have the great battery life return? Are there any tips on what was causing the issue? I see AT&T actually pulled the Kitkat update due to battery issues several months ago.
Thanks for the info,
Rob
No battery drain on my device. I'm on all stock Verizon and I did a factory reset after the 4.4.4 update. Battery life is excellent and I get through a 24 hr work shift with about 20 percent battery left, about 3 hrs SOT. I'm sure you can get an older ROM version by asking in the thread of the ROM you choose if it isn't available in the OP. Many fine folks here keep old copies. Good luck buddy!

Thanks I appreciate the reply.
The oldest ROM it originally came with is 4.4.2 so I don't know how much that would help your case. Maybe the newest 4.4.4 can help if you still have problems on 4.4.2 on your new phone (if it isn't 4.4.4 already)
I've had the phone since release date and never had a battery drain issue. The battery life was great at launch and has gotten a bit better with firmware releases.
Before I had the M8 I had a Gnex. On that Gnex android 4.4.4 would cause the phone to get very warm and increased battery drain. It doesn't surprise me that it does it on the M8 as well.
I didn't see any battery drain on 4.4.2, 4.4.3, or 4.4.4.
Pfft with all the ROMs out and kernels to help who needs battery drain.
HTC One M8
After the update, my battery life dropped by an honest 50%.
I dont use my phone much and used to get 6 days on a charge, now I only get 3.
I realize that's more than most and I should not complain, but still.
I also had to reset my phone due to problems with pictures in my previously recieved texts not opening.
The reset obviously did not help my battery problem.

6 days per charge? Haha what?

It's true, I'm older & only use a phone to make calls, & a few texts.
No social media stuff or anything like that, all Forum stuff is done on a tablet or computer.

O+O - Disastrous battery life due to CM12?

Hey all !
I am back to O+O since 1 month as I was able to find a bamboo version.
Previously, last year, I owned a normal O+O running CM11 and I was really happy with battery life. I was wable to go trough my working day and then get a drink in the evening and keep battery life until morning.
With the Bamboo one I have now, it is impossible. I am around 10% of battery life near midnight. The only differences I see are :
- Bamboo cover (I don't think it is impacting battery life)
- The phone is 1 year old, perhaps the other owner did something wrong with the phone and ruined the battery
- CM12
I think the answer is in the version of CM ... Can you confirm me that ? Do you know if I can downgrade from 12 to 11 ?
My phone is used at work, not too much, I shutdown useless services and connection as LTE, Bluetooth, NFC, Location, ...
So that's really annoying I am already lowering my usage of this fabulous phone to be able to reach a full battery day and it is getting me sad
Thanks in advance for your help and toughs and excuse my poor english

I'm guessing its going to be due to CM12 which has poorer battery life across different devices compared to previous life on Kitkat. You can go back to kitkat or run both via multrom which is what I do. You can compare both and I clearly see that kitkat standby time is far better with probably an extra hour or 2 screen on time. Is your bootloader unlocked? If not your going to need to, to flash back to previous android versions.

I had also the feeling the issue is caused by CM12 and Jelly bean.
thanks for your idea of multirom, I am going to have a look at that tonight !

Its definitely worth it, theres a guide to booting lollipop and kitkat roms alongside eachother in the thread below. Sounds tricky but once you get the right files together its fine.

MultiRom is installed and updated, I am now checking your loink to get the right version of KitKat rom and I'll install it.
I'll come back here with my impressions asap.
Thanks !

Unlocking the bootloader

Are the devs anywhere near TA backup? Should I wait or should I just unlock? Is it worth it?

Yeah, I'd say the decision ultimately depends on why you want to mod your device. There isn't much development for this device, and the two custom ROMs are either not going to be supported much longer (Turbo) or aren't working very well (Carbon). So, first you'd need to be good with manually updating your firmware, patching DRM keys, hoping someone still updates kernels, etc. Either that or your excellent camera goes to waste with green pics.
I wanted better sound and so, from that perspective I am happy I rooted and set up Viper. However, on the whole I'd probably not have unlocked my bootloader because applying security updates is time consuming and there aren't good close to stock options in terms of zip flashable ROMs.
Overall, I'll never buy another Sony device as the DRM key fiasco is utter bull****, and my specific device has a couple problems.

well, stock get sh!t battery and its not only me though.
yes with stamina its good but still I should easily get 6 hours without stamina, here I got stamina on battery perferred and still barely touching the 6 hour screen on time...
I litterally tried every thing, I think my battery is leaking XD because if i use my device straight I still get 6 hours without stamina mode enabled, but if I occasionally use it I still get 6 hours even less, because when the screen is off battery still going down like a b!tcH its like a sale you know? XD in 6 hours the battery dies wether you use it or not XD

Experience is definitely personal. My average battery use (presently 18 cycles on Accubattery) is about 8% per hour screen on and 1.5% per hour screen off. With the screen off I stream quite a lot of music, so I'm probably more like 1% per hour standby. Full battery estimates are nearly 13h screen on, 55h screen off and 30h combined.
I've typically been stock, but rooted with DRM patch. I tested Turbo for a short while but found the system UI customizations lacking, sound not all that great, and battery was worse.

OOS11 Terrible battery although good on 10

I used OOS 11.0.1.1 for 3 weeks now. Although my phone is 2 years old now, my battery was very good on OOS 10. I literally walked with 30% battery in the day and had no problems. Then i updated to OOS11 11.0.0.2 ~ Performence is good but i had to charge my phone something like 2-3 times a day ;(;(. Now i downgraded back to OOS 10 using the MSM tool.
[Update] I lost Widevine L1 after going from 11.0.1.1. to 10.3.8. It comes back when i upgrade again.
I've got a backup of my persitent partition back from 10 when 11 was not released yet. I thought bringing the phone to the same OS as from where it was extracted and lock it again could fix that. Probably someone knows something about it but i am not going to experiment with that ****.
Wtf is OnePlus doing... Have also a cheap One UI 3.1 tablet and it runs like butter on Android 11. Lol i can even disable fastcharge and limit the battery 85% in the settings and damm the UI is good. Think my next phone will be a Samsung... Sure i miss the root but Oxygen11 ... Wtf. Its not only the battery... I like the OneUI like effects OnePlus has put into it but they are terrible implemented... The animation are literally lagging and dont look near as good and the roms are not near as functional as the ones from Samsung ;(
Anyone had a similiar experience?

Did you tried to factory reset the phone after updating?
I know it is a painfull procedure to set up your device from scratch,but in many cases,this is the best way to solve any update issues.
If the problem persists,then yes it is better to downgrade.
I was in android 10 with my Oneplus 7,and had updated to the beta version of 11,but due to several issues,i downgraded to 10.
Even though my device is almost 2 years old,i never had any excessive battery drain issues,which ever was my android version.
After a few months,when android 11.0.1.1 came out,i tried again.
Its about more than 1 month now,and my phone is working without any issues,BUT,in case that something was about to go wrong,after the update,i tried a cache wipe,not data and cache.
In battery performance though,i must say that i lost about 1 hour SOT,for a full charge comparing to android 10,but it is better in idle times,where i lose about 1% every 3 hours.
Maybe you should give a try to that android version,and now that you know the way how to downgrade,you can do it again.
