How is the battery back-up on 7.1.1

Before flashing i would like to know what is the battery life after updating to official 7.1.1.
hello I have tried the backup and the autonomy of this stock 7.1.1 and it is not very good it is the same as stock 6.0.1 a little bit worst but if you flash stock 7.1.1 (NOT the backup) its better than the 6.0.1. I have flash this (XT1563 7.1.1 NPD26.49-24-1 Latin America) https://github.com/motoxplay/stock

Checking bootloader version on the phone

Hi, how do I check my current bootloader version that is on my phone? And how do i know what version of bootloader will be in any stock rom i want to flash?
I don't want to overwrite with older bootloader. Need to know the current and the next one i will flash.
My device is from Europe and I have NPN25.137-92 installed.. I think this is not the latest stock nougat for my region.
Cheers.

No need to push your question everyday. If someone is able/wants to answer he will do.
First of all: NPN25.137-92 is not the European firmware, it's the one for India and Brazil.
The latest one in Europe seems to be NPN25.137-93-14, since yesterday there is another update with version number NPN25.137-93-18 out incl. August security patch but until now only US users (software channel RETUS) have confirmed it. For India/Brazil (your firmware) the latest Nougat firmware is NPN25.137-92-14.
Have you fastboot flashed some firmware on your device so that you are on NPN25.137-92 now? That could be the reason you donĀ“t receive any further OTA updates.
Your bootlader version should be visible when you boot into stock recovery.
Yes, I must have flashed pretty wrong firmware, and now I want to get back on the track. Though I dont remember and I dont have knowledge what was flashed before that. Now I wonder what should be my next step in order to have latest European nougat, or oreo.

Flash latest european firmware NPN25.137-93-14 via fastboot. It can be found somwhere here in the Moto G 5+ threads or you can download it with Lenovo Smart Assistant: https://support.lenovo.com/de/de/downloads/ds101291
That should keep you back on track.
If you can't wait you can update to Oreo with the available OTA found here:
https://forum.xda-developers.com/g5...fficial-moto-g5-g5-plus-t3848246/post77856408 ( Read OP of that thread to find out how). But as I posted above there's a newer nougat firmware out in the US so you may not receive future Oreo updates if you use this OTA.

Need an advice: I'm currently on POTTER_NPNS25.137-93-10, OTA says i can update it to POTTER_NPNS25.137-93-14.. Then I could get Oreo OTA from the thread above. In case of any further trouble: will it be safe to return to nougat POTTER_NPNS25.137-93-10 via fastboot? If yes, if then I update again to POTTER_NPNS25.137-93-14, it is safe to take nougat OTA again? And then oreo OTA again? Hope you get my point.

No, that's not safe. Downgrading is always a risky thing because of the bootloader and taking OTA after that could completely hardbrick your phone.
So if you're once on 93-14 you shouldn't flash an older firmware than this. Same applies to downgrading from Oreo to Nougat.

Well, in case of firmware, I cannot find direct 93-14 fastboot rom for download. I have found 93-10 only, that's why I'm concerned about not having the most up to date rom version on my hard drive to flash in case of<>.

bootloader unlock Can You Receive Updates via Ota or No?

I am curious about these issues, my question is the following when I unlock my Bootloader I can do an update via OTA when it arrives on my device? Or is my phone going to have Hard Brick?
I want to give a Downgrande on my smartphone but it is still in stock without any modification. And through the tutorials I read ask for the unlock Bootloader. My intention is to only downgrade. A friend of mine gave the following idea: "unlock the bootloader to then downgrade and after it has been successfully done." I search how to lock the bootloader again using CMD to put a system with the bootloader locked and so in the future I will be able to receive updates via Ota. " Does This Worker Ideas In Practice?
This my Frist Post here If I make a mistake, tell me, we will not repeat.:fingers-crossed:
When it comes to being able to receive updates when bl is unlocked, that's a yes, it will work fine and won't affect your phone's functionality.
On the other hand downgrading is generally a bad idea. The problem is, when you update your phone your bootloader also gets an update. All parts of the OS except for the bootloader can be downgraded to a previous version, and if you do that, the downgraded OS can function normally on the newer bootloader.
Now comes the tricky part. If you try to do an OTA on a downgraded OS with a new bootloader, the OTA will treat the bootloader as if it were the old one, and will overwrite parts of it that it shouldn't, which will corrupt it. And there you have a pricey paperweight.
The only way of updating a downgraded device is to flash it clean with a newer version (or the version same as the bootloader).
Now what is the reason you'd want to downgrade?

My bootloader is unlocked.
I wanted to upgrade to the latest firmware and because I was rooted I flashed the firmware I was on at that moment (no down - or upgrade) again and after that I was able to apply and install every single OTA up to the latest. I could have flashed the latest Oreo firmware directly too but I wanted to test this way and to update by flashing latest firmware would have been possible after that too.
So updating via OTA with an unlocked bootloader was no problem for me.
In the end you get the unlock code from Motorola itself and it would be kind of strange if they won't deliver updates anymore for a feature they provide for their devices.

I am planning on to unlock bootloader only will I continue recieving official updates from Samsung and able to install them (not flashing that, OTA ones). I am not going to install custom recovery or kernel or even custom rom. Will it work that way?
