[Q] D802 lose system time and brightness setting on reboot - G2 Q&A, Help & Troubleshooting

My D802 seems to be losing some settings when it's rebooted.
1) On all reboot, the brightness is back to 100%.
In settings/display, I set the brightness to 60% with auto disabled. After a reboot, the display is back to 100%.
2) *Sometimes* it sets the system time to random
I observed this only twice. The time remains correct on other reboots. The time jump happens when I turn off the phone and leave it off for a few hours, and turn it back on. Both the hour and minutes are wrong. "Automatic date time" and "Automatic timezone" are both disabled. There is no SIM card and no WIFI enabled.
Does it look like a hardware problem? Can someone help see if you also have these symptom, especially 1) since it happens everytime for me.

It is happening for my G2 as well. Did you discover what the issue is?
I have my suspicious that could be the lack of SIM card, as I am now preparing the device for my brother and he needs a micro seem which he does not have... The device worked as intended before the hard reset, and I tried to reset it again, but the issue persist...
Thank you

XV6800 Problem... Need Help

So this problem has been going on for the past 2 days, and its very perplexing. Any help would be much appreciated.
For whatever reason, my phone has stopped automatically turning off after X minutes.
I'm talking about when you go into Start, Settings, System tab. There's options for automatically turning off the backlight after X amount of minutes (one option for when its using battery, another when its on AC Power).
The backlight auto off works just fine. After 1 minute, the screen goes semi-dark, but not blank.
What's not working is the Power setting, where you go to Power, then Advanced, and then both battery power and external power, you can have the device turn off if not used for X minutes. I've tried 1, 2 5, 10, and none of them seem to work.
The device only turns off the backlight, but then remains on, draining the battery at incredible speed. I need to manually keep hitting the hardware power button on the right side of the device to get the screen to go off completely.
Any help, ideas, suggestions? Thanks!

Are you running custom or stock rom, have you thought about possibly doing a hard reset. besides adjusting those settings have you tried something else. Was anything instlled just before this started if so what....I know thats alot of questions but it might help..
I thought dimming the screen was the manufacturers idea of turning off....mine has done that since day one. I too have tried everything and thought that was normal.
Hmmm, Mine dimms then turns off IE: 1 Min to turn off I'd say 30 Seconds it dimms and 30 seconds later it turns off.....
I'm using a stock ROM, havent installed anything "new" in the past few days. I normally run a bunch of various programs though, but I wasnt having this issue before.
I did a hard reset. Everything was fine. Then I ran a backup and it reinstalled all my programs/files/settings, and issue returned.
So its obviously being caused by oen of the programs I use, I just dont know which I guess.
Edit- Upon further investigation, I *think* its Palringo. I removed it completely, and everything seems to be ok again

Self shut down / switch off in standby

Hi All,
I'm experiencing a major issue with my HD. it will self shut down or switch off after entering standby mode, ranging from few minutes to few hours (3 hours to be precise, the last time). Is there anyone having the same issue? if yes, is there anyway to solve this?
please help.
regards,
sanchez
Check if the battery is properly fixed. I mean, that it doesn't move. If it doesn't a perfect contact, as soon as you move or touch the device a bit harder than usual, it can turn itself off.

i did and still it shuts down.. it shuts down randomly in standby mode, ranging from few minutes to hours (maximum 8 hrs so far). the seller refused to replace mine because
1) the phone didnt shut off in standby mode when they were checking it
2) they refused to test it for a longer time
I have the same problm. Every now and then it will shut down and reboot. Annoying when the phone wakes me up in the middle of the night (htc boot-sound)

yours actually reboots itself? mine only shut down / switch off by itself. my only self found solution is by deactivating standby mode, so the phone will go the stage of switching backlight off but screen is still visible... its draining the battery =(
It's not that strange that the phone reboots, that is what happens if a program crashes.
If your seller won't test it for a longer time, try going to an HTC point.

Actually that was what happened with my Diamond. Even hard-resetting the phone did not help.
I sent it back for repairs twice, but the problem persisted.
You device might be faulty, if a hard-reset does not solve the problem.

Wi-Fi Not Allowing Deep Sleep

So I posted this in a different thread but figured I would post it here to see if anyone could duplicate my findings. I have a Note3 from T-Mobile and for whatever reason leaving the Wi-Fi on will not allow the phone to go into deep sleep mode. I noticed when I was down to 40% battery after 10 hours with only one hour of screen on time. After running some tests I had only 2 minutes of deep sleep those entire 10 hours (tested using BetterBatteryStats) I tried setting "Keep Wi-Fi on during sleep" to Never and unchecking "Always allow scanning" under advanced network settings but neither of them fix the issue. In fact, after several tests I concluded that setting never for "Keep Wi-Fi on during sleep" wasn't even functioning as my access points still showed the client connected while the phone was asleep.
Can anyone else confirm this issue is actually a bug and not just my phone being defective?
Here's my original post on the topic regarding how I found the problem and what I have tested so far:
OK so after only 2 days of owning this phone (got it late Monday night, the T-Mobile variant) I finally figured out why I'm getting such bad battery, and I suspect the same thing may be happening for the other people in this thread. Hopefully this information helps at least one person.
My battery stats was almost identical to all the other users in this thread that had bad battery, I would get barely around 10-12 hours on the phone with less than 2 hours of screen on time. After using multiple apps to track down the issue I finally got what it was.
Wireless. Yes, wireless was my cause. But the thing is Wi-Fi didn't show up at all in any of the battery apps so I assumed it was a non issue. I've had other phones and have always kept the wireless turned on the entire time without problems. The basic problem is not that Wi-Fi is using power itself but it's that by default the phone cannot enter deep sleep while connected to Wi-Fi. This is why trying to use apps like BetterBatteryStats will lead you nowhere initially (though they were useful in finding out what was causing the issue) You can discover this by turning on Wi-Fi and connecting the phone to a charger, then disconnecting it so your BBS information will reset. Then power off the screen and power it back on after 10 minutes. You'll notice in the other section that deep sleep will have less than a minute time while awake probably has close to 9 minutes, if not more. This is with everything else turned off, almost no apps, and no special Samsung stuff enabled.
Under Apps > Settings > Wi-Fi > Menu > Advanced there are two options that should help this: "Keep Wi-Fi on during sleep" and "Always allow scanning" I set the "Keep Wi-Fi on during sleep" to Never and unchecked Always allow scanning and rebooted the phone. And low and behold...nothing. Yes, these options don't work (at least not to fix this problem) The phone still won't enter deep sleep mode while the wireless is enabled. Based on my company's wireless devices I can see that even with the screen off for well over 10 minutes it still shows connected as a client meaning the wireless is not turning off properly while it's in sleep mode. Or perhaps it can't go into sleep mode because the wireless is on which stops it from going into sleep mode and turning off the wireless. My guess is that it's a Samsung bug.
The reason why there's so many people here to get good battery usage is because they're either used to turning Wi-Fi on only when needed and keeping it off. You'll also not notice it if you have more than 6 hours of screen on time because you could easily assume that it would make sense that you phone would only last 10 hours total with that much screen on time, even though it should have technically lasted 20+ hours with only 6 hours of screen on time if the phone could have entered deep sleep.
So what's the real fix for this? Unless it's by design my belief is that it's a bug and won't be fixed until Samsung/T-mobile notices. I can't test to see if the same thing happens on other carriers so if someone feels like testing this theory out it would help.
For now, I guess we're just left to manually turning Wi-Fi on only when needed and leaving it off in all other cases. For those that have the T-mobile variant, make sure you also go into Settings > General > Backup and reset > Collect diagnostics and uncheck the "Allow Diagnostics" as that will probably be the highest offender of Partial Wakelocks (it'll show up as com.carrieriq.tmobile.wakelock or System Manager Application)
If anyone wants more information on my testing let me know!

That's because the 'Keep WiFi during sleep: Never" setting only disconnects, it doesn't shut down the WiFi radio.
You're going to have to use a manager (Like Deep Sleep Battery Saver).
Or just hit the toggle yourself... If you're going to keep it disconnected in sleep anyway, just swipe down the notification bar and hit the bloody toggle.

The problem is that it doesn't disconnect, the access point 100% shows it is connected and transferring data every now and then. But the real issue isn't weather it disconnects or not but it's the fact that Wi-Fi will not allow the phone to go into deep sleep mode. For now I am fine with switching Wi-Fi off and on as needed, but with no other phone have I needed to do this before and definitely seems like a bug.
But regardless, what I'm trying to figure out if this is a legit bug that I should submit to Samsung/T-mobile or if it's just my phone and I should ask for a replacement. If anyone has BetterBatteryStats and could test this with their Note3 that would help.
My stupid phone has just started this same issue!!!! Freaking annoying, after only 8 hrs from 100% charged state, the battery is at 46% with only 26 mins screen ontime, I checked out that the phone never goes into deep sleep. What is going on and what can be causing this? Did you manage to resolve your issue?
PS I checked out wakelock detector but doesn't tell me a thing, as what program is keeping the phone awake all the time. Starting to hate this phone and miss my S3
What is your GPS accuracy setting set to? GPS, Wifi or Networks? Try setting it to GPS only.

Well, your issue looks pretty similar to mine, which I solved with this Xposed mod (you could give it a try if you're on KitKat): http://forum.xda-developers.com/xposed/modules/mod-wi-fi-deep-sleep-t2752947. I was experiencing that even when "Keep Wi-Fi on during sleep" is set to Never, Wi-Fi still was awake most of the time according to battery stats.

phone won't enter sleep on it's own

All,
I've got a stock Nexus 6P, Android 6.0.1, build MHC19Q.
Sometimes the phone will go to sleep and sometimes it won't. In the settings, Display Sleep setting I have 30 seconds as the value, but I've seen my phone stay on for way longer, sometimes until I hit the power button.
I've tried several changes to the time but it doesn't seem to help the times it stays on, it just changes the time for the sleep when it does work.
To explain exactly, when I stop using my phone and I'm on the home screen, if I leave the phone alone for several minutes, it will not sleep, no matter what value I put in the setting. Other times it seems to sleep without a problem.
I've not been able to determine if some app is holding it awake, and I don't see any pattern the would point to any other condition that keeps the phone awake.
I looking for additional ideas to troubleshoot the problem, it just stays on and runs down the battery.
Ideas?

Download and install GSAM. It will tell you specifically which app is keeping the screen on.
If it days Android, System, or Media Playback is the highest, it may be a tweak / custom rom / kernel issue.

No DeepSleep, phone always Awake

So I've been having this problem since a few days. It happened a few times in MIUI 10.3.5 global version then after updating to 10.3.6 I had it ALL the time.
Checking battery stats gives no info on this. Apps shown to consume battery are the ones I use and they only have 1 minute of keeping screen awake timer.
I've no idea what's causing this and I don't want to root my device as some of my applications have aggressive root detection and won't work.
CPU spy shows 0 deep sleep and 660 mhz is used instead of sleeping.
Steps I've taken so far:
The only temporary fix I found was to disable MIUI optimizations in developers options but that isn't of any help anymore.
Factory reset, playing around with different settings including turning off sync, wifi, mobile data and airplane mode on phone still didn't sleep.
Logged out of MIUI account and haven't logged back in after factory reset.
Turned location off/tried GPS only.
I'm going to reflash my firmware today and post the results, need any advice on this as I've scoured the internet but found no solution.
Probably fix(?) Not turning to sleep mode xiaomi
Hi, I actually faced the same problem before and like yourself, I turned off my mi optimization and I use Xiaomi Redmi Note 5. This is how it works for me, so it might help you? So I turned the mi optimization off, and later turn it on back but my phone has yet to enter the sleep mode even though it should be even after the set time. I restarted my phone and it didn't work either. So what I did, is basically turn mi optimization off, reboot and turn it on, to reboot again. I know it might sound strange but I have a theory, if we reboot the device after turning it off and on, it might as well go back to normal as we, according to the warning, need to reboot our device after turning mi optimization off.
