This firmware resolves the issue: http://updato.com/firmware-archive-select-model?record=1D0F4E90377111E7963AFA163EE8F90B ! Confirmed 0% drain over 3 hours on standby would have def lost at least 2-3 % by now.

Look for BTU firmware T820XXU1AQDC if the link expires.

Does anyone not charge their tab overnight? That negates all of this *****ing. Then it is at 100% when you wake up. Win win for all.
[Samsung Galaxy Tab S3 Guides, News, & Discussion] undrwater:
I charge on the weekends. I use the tab to take notes for work during the week.

Currently, I have tasker turn off wifi when the screen is off. I have updated, so I'll try without tasker.
[Samsung Galaxy Tab S3 Guides, News, & Discussion] BarryH_GEG:
I have a EU LTE Tab S3. It's connected to Wi-Fi continually when I'm home. I lose 2-3% when the tablet's sleeping overnight. I didn't know there was a Wi-Fi bug until I saw this thread. But I do have a Netgear R9000 which is a beast of a router. Is there any commonality to the Wi-Fi drain problem? I don't remember which Samsung phone it was but one had a big problem with D-Link routers specifically.
[Samsung Galaxy Tab S3 Guides, News, & Discussion] mva5580:
So it's now referred to as "*****ing" when people are noticing a very clear obvious issue with a device and would like to see it fixed. Amazing. Maybe for the S4 they can just not put speakers on it and we can all be considered "*****ing" because we should all just use headphones?

Anyway......completely ridiculous that there are constantly issues with these things. I TRY to switch away from iPad constantly and there is just not an Android tablet on the market that is in the same ballpark and at this point I doubt there ever will be. I've lost 8% of battery life today already and the thing has been on for like 2 and a half hours, and of that time I've probably spent like 5 minutes actually using it. The rest of the time it's just been sitting there, screen off. Pathetic. An iPad would still be at 100%, MAYBE 99%.

That is not the latest one. The latest AQF3 is OTA only right now after you update to AQDC for BTU via ODIN.
[Samsung Galaxy Tab S3 Guides, News, & Discussion] muniz_ri:
QD6 is the latest firmware for the u.s. variant.
[Samsung Galaxy Tab S3 Guides, News, & Discussion] undertaker2k14:
US variant is always 2 months behind the rest just like it was for the S2 so you want to be running the BTU firmware on this as that seems to be getting updages first. The country code is largely irrelevant as the device is 100% the same, some countries csc restrict the 5 ghz bands to only lower channnels like DBT (Germany) but no such issue with the BTU/UK firmware.
[Samsung Galaxy Tab S3 Guides, News, & Discussion] muniz_ri:
Thanks for the heads up, but I'm good with qd6.
[Samsung Galaxy Tab S3 Guides, News, & Discussion] undertaker2k14:
Tried to find the root cause using wakelock detector and greenify, didn't yield much. The problem is likely at the system firmware/wifi driver level. I suggest all folks start returning their S3s , teach Samsung a lesson.
[Samsung Galaxy Tab S3 Guides, News, & Discussion] undertaker2k14:
AQF5 build came out today for Korea, trying that now. The way they are increasing the build numbers, hopefully they are actually fixing something. Interestingly this had a modem file too though the SM-T820 is wifi only.

[Samsung Galaxy Tab S3 Guides, News, & Discussion] BarryH_GEG:
If you don't mind the extra money get a LTE version. I have a SM-T825 (LTE) from the UK and it has no Wi-Fi drain issues. It'll drop one or two percentage points in battery connected to Wi-Fi overnight off its charger. It obviously has a different radio than the Wi-Fi only version in order to support cellular connectivity.
[Samsung Galaxy Tab S3 Guides, News, & Discussion] undertaker2k14:
The extra 200-300 is a bit hard to swallow if you dont need LTE for something that should be working right in the first place.
[Samsung Galaxy Tab S3 Guides, News, & Discussion] acc3d:
FYI, a new firmware version has been rolled out to US devices on 07/19/17.

After a few days of testing, the WiFi battery drain bug seems to be fixed. I let my tablet sit for 16 hours and it only dropped 2%, which is much better than before.

Screen-off memo is also much improved, and overall tablet performance seems a bit better.

Can anyone else comment on standby battery drain?

Device name : Galaxy Tab S3

Model number: SM-T820

Android version: 7.0

It seems fixed and indeed is fixed for the first charge after a new update but it will come back sure enough, trust me :)
[Samsung Galaxy Tab S3 Guides, News, & Discussion] bimmerboii:
It has been a week already since installing the latest T820XXU1AQF3 update and battery standby time on my device has improved a little. Wifi battery drain is still there.
[Samsung Galaxy Tab S3 Guides, News, & Discussion] volcolm:
Mine wasn't experiencing battery WiFi drain (doubt Canadian firmware releases to be different but we did get the S3 before the US) but just fast drain in general. I can confirm that recent firmware updates have improved the useability of the device in terms of battery performance/SoT(read that as "off time" because that's where it was happening) overall.
[Samsung Galaxy S8+ Questions & Answers] usfbulls:
Hi All,

I got a new S8 Plus this past Friday. Nice phone, but after spending a few days with it, it seems to have some issues.

The SD card seems to mount and unmount randomly. I have a few apps that are on my SD card and every now and then I just get the gray android generic "App Not Available" icon in place of the correct app icon. Then eventually it may show up again, or it may take a reboot to show up again.

The other thing (more annoying to me) is that the phone randomly reboots without error. No heat, no other issues that I can find, just a complete reboot. Again, there is no app that seems to do it, no excessive (or any noticiable heat at all for that matter). Just a reboot. I know it does it overnight as well because I can check the system up time, and I can also tell because I have iris scanning set up and after a reboot you have to plug in your pin number no matter what.

FYI - I called Samsung and they had me clear my cache and reboot to safe mode. Other than that, they did nothing else, said to watch it. And did not indicate anyone else was experiencing this.

Just wanted to know if anyone else is experiencing this.

Thank you!
[Samsung Galaxy S8+ Questions & Answers] Xealot42:
A lot of folks are experiencing this, myself included. Try moving any apps you have put on your SD card to back to internal storage, that stopped the random reboots for me. I've removed my SD card for now, hoping a software fix is possible. If this "SD Card Monitor" app is correct my card mounts/unmounts 100+ times per day, even when sitting untouched on my desk!

[OnePlus 3 Questions & Answers] ephumuris:
I'm after trying something new after keeping my OP3 stock for a good 8 months or so.

Was wondering if there's a way to unlock bootloader without wiping my data or is there a no root way of backing up my data?

Also was hoping to find a rom where my banking apps still work although I have a feeling that might not work.
[OnePlus 3 Questions & Answers] Anova's Origin:
If you have the technological know-how to exploit the current OOS security bug, you could downgrade your OOS version to OOS 3.X.X or 4.0.1 through OTA spoofing, then exploit this security flaw to unlock the bootloader without wiping your phone. As for how the first flaw works, I've got no idea.

[ZTE Z7, Z7 Max, Z7 Mini] livgrave:
Hi everyone, I have Nubia Z7 Max and its spec sheet says that it has 802.11ac. Currently I don't have an AC router, and on the current router and the N connection standard I have 150Mbps link speed. Since I also have a gigabit LAN, with a server for exchanging data between devices, would I gain any kind of speed by switching my router to a one that supports 802.11ac? I know it depends on how many spatial streams and what kind of bandwidths the phone has, but I can't find this info anywhere, is there any detailed info for the AC wifi configuration on ZTE Nubia Z7 Max? Thank you...

[Google Pixel XL Questions & Answers] PFusion:
I need some help and I've looked all over but the information is fragmented and there is too many unfamiliar acronyms used which make it incredibly difficult for some like myself to catch up. So for the benefit of others who may be new I wanted to get some additional guidance.

I got the Pixel XL Google Version

Objectives:

1. Root with the ability to hide root so other apps will work

2. Native Mobile Hotspot

3. The ability to easily receive android updates without having to reflash etc..

4. Stay close to stock if possible, but willing to explore other options as long as security is trusted, and has good

compatibility.

5. Security is a concern, I tried a rom in the past with a Galaxy S4 and swear it had a backdoor installed in the rom.

What do you guys recommend? And how do I go about doing it?

Thank you!
[Google Pixel XL Questions & Answers] parakleet:
If security is truly a concern you will not unlock your bootloader and root your phone.

Otherwise it all depends on which version phone you have, Verizon or Google?
[Google Pixel XL Questions & Answers] mikaole:
1. You need magisk root for that.

3. No updates when you are rooted

4.5. Never heard of any custom rom with a backdoor. That's absolutely bull****. More likely it was an app you installed.

Unlocked bootloader is a security issue, so better to stay on full stock.

Root is a big security issue so better stay on full stock.

Jokes aside the only security issue is your phone gets stolen or you install apps outside playstore.

If you stay encrypted and use a hard pattern with fingerprint you are fine and there is always the way to delete your phone when it gets stolen.
[Google Pixel XL Questions & Answers] PFusion:
My point about security really was that it's quite possible a ROM could have a backdoor. That a side..

Root is not a big security issue for me as long as the rom is trusted etc..

Shouldn't I be able to turn root off then be able to update and turn it back on again?
[Google Pixel XL Questions & Answers] alluringreality:
It's possible to root to one slot with SuperSU while the other slot remains unrooted, and then the phone can be switched between slots with TWRP or fastboot commands. Kernels have been posted with safetynet patches, to hide that the bootloader is unlocked, but I'm not sure if any are available with the software version on my phone's current slot. As noted, Magisk can also hide root and that the bootloader is unlocked, so it's probably less hassle than trying to root and hide using SuperSU.

FlashFire can use the OTA to update and stay rooted with SuperSU. The past couple months I've used FlashFire to update my phone, and it seems quicker and easier than the sideloading and reinstalling process I had been using. I'm not aware of anything similar to FlashFire for Magisk users, so to me it seems like you would have to decide if 1 or 3 is more personally important.

While reading I got the impression that I might be able to uninstall SuperSU and use the OTA update, but that didn't work with SuperSU the times I tried it, so I presume something SuperSU changed or something I did with root must have caused the update to fail. I haven't read the Magisk threads as much, yet I've seen that other SuperSU users also indicate that OTA updates no longer worked for them after rooting the phone.
[Google Pixel XL Questions & Answers] PFusion:
Wow thanks for the great reply! It's so refreshing!

What do you mean by root one slot?
[Google Pixel XL Questions & Answers] alluringreality:
The phone has two "slots" for Android. The basic idea is that you have two copies of Android on the phone that share the same user data. On a stock phone it's intended to allow for less noticeable updates, and it also can allow the phone to fall back to the previous software version if something goes wrong with an update. On the May update my phone did automatically switch between slots, due to what is discussed in the second link below. The first link below gives some information and additional links to discussion about the slots on these phones.

Well for starters, try going in to the recovery and clear Cache and Dalvik Cache. See if that works. And if that doesn't, then you always have the nuke option, download a full ISO for OOS and flash it to fully reset your device. (You can also simply reset through the recovery but flashing OOS all over again might fix any faulty firmware)
