Power consumption in flight mode - Fire Q&A, Help & Troubleshooting

Hi,
I have a Fire 7 (2017) and fully charged in flight mode with no use at all it went from 100% to 85% in about 24 hrs.
Is that a normal battery drain or should I look for some app misbehaving?
And what exactly is flight more on this device?
I mean is there any difference between a device in flight mode and a device with simply wifi, blutooth and location turned off?
Many thanks!

Flight mode is Airplane Mode. By default it turns off all methods of wireless communication, but they still can be toggled. In Fire tablets, this only affects Wifi, Bluetooth and assisted GPS, but in other devices it also turns off things such as cell radios, NFC, WiMax, etc.
Check for any rogue apps running in the background.

The observed idle fall off rate (~0.6%/hr) is typical for FireOS v5 and the stock app portfolio. The device itself can do much better; I observe an idle drain rate of <0.1%/hr on a nearly identical 5th gen device w/custom ROM. Unfortunately, swapping out FireOS is not an option for 7th gen owners.
For reference, an idle drain rate of 0.5-0.8%/hr is fairly typical for most mobile phones running Android 6+ with all radios/services fully engaged. Add a few 10ths for devices running stock Lollipop and below all else being equal (which is rarely the case). FireOS v5 is based on Lollipop.
Engaging airplane/flight mode disables all onboard radios, location and 'sync' with a single control. Disengaging restore those items to their previous state.

[Q] KFHD Battery Question

I've tried search for an answer, but I can't seem to find a thread specifically for this device & issue.
My wife got a Kindle Fire HD 7 on launch day. She's been really disappointed with standby battery life. As is today - she loses 2-3% per hour in stand-by. Is that normal with these devices? If she turns wifi off during sleep it appears like it uses almost no battery.
I have a Nexus 7 - with Wifi policy set to Always on - I lose maybe 5-7% per day.
Now here's the kicker - she's worked with Kindle support and they sent her a new unit. Unfortunately she's seeing the same behavior. She's fully stock, no root, doesn't want to modify. I'm cursing amazon for gimping the battery stats in ICS. At least I can see on my Nexus who/what is using power.
I've had her try resetting the device and just leaving it not setup (no apps, just clean) does the same thing. Maybe I set her expectations too high, but I've owned a Galaxy Tab 7 Plus and the Nexus 7 - they use no where near the amount of power in stand-by. Heck my galaxy nexus was a 95% after 4 hours of standby; her fire was at 90% with absolutely no use - and I actually used my phone a bit whereas the kindle was just sitting in the living room.
Of note: the kindle itself does not appear to get 'hot' when in standby.
Did I set her expectations too high for a 7" tablet? Or is there something more going on here? The only thing I haven't tried is having her deauthorize her kindle and connect to my account (to see if it's some weird 'sync' related issue).
Sorry if I ranted a bit - I pride myself on figuring this kind of stuff out by lurking on forums - this one has me stumped!
That is not normal. I had lots of issues trying to figure out the KFHD battery drain issues and have been cautious on what to install. However if you do have location services turned on, it will drain the battery like no tomorrow. Once I turned it to off, I noticed my device will finally achieve deep sleep. Also check any apps that auto update data. The stock email is fine but things like hootsuite will keep it awake if you let it auto check for messages. I also noticed certain widgets such as Pandora may keep it from going to deep sleep even if I never ran the app. I found the KFHD to be very finicky. I went over to Nexus 7, I don't want a device that requires babysitting.
What is the best way to tell if the kindle is in deep sleep ?

Yeah - location services are off. Just did another factory restore and signed in with my Amazon account (nothing configured beyond sign in) to see if it still does the same thing. My nexus uses less power web browsing than the kfhd in stand by

I use cpuspy app, it only works on rooted devices.
Also OP, make sure your wife manually turns off the screen when the device is not in use. I noticed the battery drains rather fast if you let it time out in that 5 min. Also use auto brightness. Otherwise I'm not sure what else to tell you. Once I found my culprits, the battery life was much better.
On a side note, don't use any apps that modify wifi settings. That will break whatever hidden setting that Amazon has programmed and you can't get it back without a rest. Unlike the first edition KF, wifi will stay on, at least for exchange emails.

Yeah she's button OCD - so no problem there. She's used manual brightness set at like 30%.
I specifically did a factory reset last night on the 'old' device - signed in to my account (to remove her account as the 'cause'), charged up to 100%, unplugged and let set overnight (10 hours on the nose) - screen was off the whole time. Lost 33% battery! Gosh I wish I had a full battery stats Now she's looking at the new Nook.

My kindle fire hd 7, drains the battery even when its completely turned off (shut down).
Last night the battery goes from 29% to 9% in 15 hours while the tablet was turned off.

[Q] Wi-Fi on during sleep

Hi,
I changed the setting to turn off Wi-Fi when the tablet is in sleep mode. However, when I check my battery usage, it indicates that Wi-Fi is on almost 100% of the time.
Can I do anything to fix this?
Try better battery stats available here at XDA. Although it's designed to help you find out what's using your battery, the info the app produces will show you what programs are running the most. Odds are one of those uses wifi and that's what's keeping it on during sleep. Just remember that you'll need to be on battery and not plugged in or docked to gather the app usage info.
Sent from my Nexus 7 using Xparent Purple Tapatalk 2
Definitely an app keeping wi-fi awake. I have mine set to never turn off during sleep and I only lose 3-4% overnight. Wakelock Detector is another app that can identify which apps are keeping wi-fi active.
Thanks, I'll try to see if these apps can diagnose the problem.

[Q/Issue] Deep sleep with wlan on?

Hi!
I just noticed that my phone does not go to deep sleep if I have wlan on. Though I do not have any long wakelocks according to BetterBatteryStats, just some minutes total while the device have been awake for much more.
Stock .534 unrooted, newly repaired with _only_ BetterBatteryStats and CPU Spy installed. No accounts added etc.
Wlan/Advanced: "Always on"
Location-based wlan: "on"
Low battery mode: "on"
STAMIN mode: "off"
Location based services "on" / "off" tested.
When I have wlan on CPU Spy reports as Deep sleep unused, and instead most of the time is spent in 300 MHz.
Any of you that can reproduce?
Have the same problem. Is that normal that it doesnt goes to deep sleep ?

No, it's absolutely not normal. Something is keeping the device awake, probably a bug.
I left the device over night,
wlan kernel wakelock for 7h, but no long-standing partial wakelocks. I don't get it, how can something keep wifi awake without actually issuing a wakelock?
Bah I have suddenly been afflicted with this issue since yesterday. Noticed battery drain from 100% to 33% with minimal use between this morning and lunchtime while at work. Currently it is charging off my laptop but only holding its own, not increasing. Only had it a week, very little installed on it.
Battery life was fine for the first week of ownership, today it lost 75% with little or no use in 5 hours, then it did not charge when connected by USB to laptop it merely held the same charge, before quickly discharging again when disconnected.
No deep sleep all day

Hi, can you please verify that you indeed do not have any wakelocks caused by any other third-party programs you have installed? Just to knwo that we are in fact experiencing the same issue. You could also try to disable wlan (and mobile data (I haven't tested to turn that on, as I do not yet have a data plan).
The application needed to test that is Better Battery Stats, available here on XDA (or on Play): http://forum.xda-developers.com/showthread.php?t=1179809

Today's issue on my phone was driven by several hours of a "bam_dmux wakelock."
edit: and no partial wakelocks so no idea of the driver.

Ok. So it might be the same issue then, though I don't really know what the "bam_dmux" wakelock is.
FYI Mine is back to normal today. Lost 3% in 3 hours of light use. Only thing I have changed is I deleted a Wifi network from my preferred list that the phone was having trouble connecting to, may or may not be related.

Bluetooth battery drain

I'm having an issue with my Galaxy Tab S2 (Nougat 7.0, international unlocked T710 Snapdragon) when using any bluetooth device with it. The battery drains like hell. After a two or three hours of using a bluetooth keyboard, bluetooth is the main cultprit of battery usage. I don't know what to do - I wiped the cache partition, did a factory reset. Nothing helped.
Otherwise, the battery life is great, but as soon as I connect it with a BT device I can see it dropping. Everytime I click on Bluetooth in Battery settings I can see there's more mAh used...
I would appreciate any help.
Nougat.. thus better downgrade to MM or Lollipop.
Dear all,
I Have same bug with My SMT-813 since update Nougat, When I use with skeaper bluetooth.
Do you have found a solution?
Did you factory reset after OS update?

Dear,
Yes, all reset.
I think it's Nougat because with android 6.01 all is ok.
So better downgrade back to 6.0.1 then.

Yes, it's happening since the Nougat update. I've already filed a bug report for it but got no answer from Samsung till today.
The only thing you can do about it is to turn it off. And if you need it you have to downgrade to MM.
Same here on t819, but its kind of fake data, in my opinion there is somrthing wrong in calculating mah consumption. My battery still lasts the same, even when using or not using bt, but it has a lot of bugs, like forgetting paired devices or failing to pair. Everything about bluetooth is not perfect on N
Hi All
Do you have news about this bug?
Workaround
I've had the same battery drain issue on my S2 since upgrading to Nougat. Yesterday however I found I could 'fool' the system by turning on Flight Mode and then turning BT and WiFi back on - Consumption back to normal! It looks weird having Flight Mode on at the same time as BT & WiFi but it seems to work.
Update
I’ve just been trying to repeat my observations and the results are a little ‘challenging’
I saw a comment in another forum where someone suggested that the discharge effect is really a false positive caused by a faulty battery monitor in the Samsung software. So a downloaded a third party battery monitor, I charged my tablet to 100% , turned off flight mode and turned on both WiFi and Bluetooth.
The main observation is that the battery was not discharging rapidly – previously you could virtually watch the percentage on the battery meter decreasing in real time. After using the tablet for a day or so for browsing and watching some short videos I compared the two battery monitors – the Samsung monitor showed the battery down to 40% - but ascribed virtually all of the use to Bluetooth! The third party monitor showed a sensible mix: mostly browser and video player with small values for other programs.
I conclude therefore that the Samsung battery meter is definitely very broken.
As far as my earlier observed battery drain is concerned there seem to be two possibilities:
1) It was truly the Bluetooth causing the drain and switching to flight mode has cleared it (unlikely in my view)
2) The drain was caused by something else but was displayed by the battery meter as Bluetooth, and when I switched to Flight Mode it stopped - either by coincidence or because the Flight Mode really stopped the drain.
Number 2 seems to me the most likely explanation. I have noticed that all of my Android devices exhibit anomalous battery drain about once a month, and a functioning battery meter shows this as Android System usage. I don’t know what it is doing but my best guess it is some sort of file scan/verification (or maybe just harvesting data!). After a system upgrade it would be quite plausible that Android wants to scan the new installation.
I have, in the past, stopped this Android process by rebooting a device, so it is not impossible that entering Flight mode has had a similar effect.
For the moment my S2 seems to be using a sensible amount of power – both with and without Flight Mode - albeit with useless reporting of the details by the Samsung monitor.

Factory Reset does NOT solve S10 Battery Drain (15-20%) when Idle

I noticed my Samsung S10 T-Mobile Snapdragon would drain about 15-20% overnight while asleep (6-8 hours) since last week or so. The drain during the day is also significantly worse, but it's easier to compare the numbers when on idle. The first weeks that I had the phone, I was losing less than 5% overnight (6-8 hours). I am not sure if this was caused by the security updates, carrier updates, or a rogue application. I made no changes to the phone settings that I can recall. My phone was connected to WIFI overnight, with cellular, cellular data, and Bluetooth on. Prior to going to bed I would charge the phone to about 80% and unplug it.
I installed AccuBattery after reading some forums and it showed that my battery drain overnight was about 2-3% PER hour. AccuBattery also indicated that my phone was in deep sleep +85% of the time. The breakdown per application does not total the 15-20% so there's something else draining the battery. Eventually, I uninstalled AccuBattery to see if it was contributing to the drain, and it made no difference.
Below are most of the things that I have tried and tested overnight while I slept (6-8 hours), all of them have been UNSUCCESSFUL at solving the battery drain. I might have forgotten some other settings that I have changed. Keep in mind that this took me over a week of playing around with these settings, and checking the battery right before and after I went to sleep.
Restarted phone (There's always someone who would suggest this if not written down)
Cleared Google Services, Google, and other Apps Cache and Data
Cleared Cache Memory (Through recovery menu - Tried this about 5 times at this point)
Reset the big 3 (Reset settings, Reset network settings, Reset accessibility settings)
Enabled Airplane Mode (Cellular, WiFi, Bluetooth Off)
Disabled Location
Disabled Sync
Disabled Always on Display
Disabled ALL Motions and Gestures (e.g. Lift to Wake, Double tap to wake, Smart Stay, etc.)
Disabled Video enhancer
Disabled Game Launcher
Disabled Bixby Routines
Disabled Nearby Device Scanning
Disabled WiFi Scanning and Bluetooth Scanning (Improve Accuracy)
Disabled Show icon when screen is off (under fingerprints - from Samsung Forums)
Disabled certain Apps (AR Emoji, ARCore, Briefing, Chrome, Game Launcher, Google, Facebook, Secure Folder, etc.)
Forced Stop certain Apps (Bixby, Secure WiFi, etc. - they seem to all come back after a couple of minutes anyway)
Enabled/Disabled Adaptive Power Saving (Tried both settings, made no difference)
Enabled/Disabled Auto Optimization (Tried both settings, made no difference)
Switched between Power Modes (Optimized to Medium, made no difference)
Change lock screen and home screen to a 100% black wallpaper
Ran Safe Mode overnight with ALL of the settings above (Airplane with Location and Sync Off, etc.) Still got a 15% drain overnight.
Last night after I got fed up with playing with the countless of options, I decided to Factory Reset the phone thinking that this would solve my battery drain problem. Well, WRONG. Still got a 15% battery drain overnight with only the core apps installed, in airplane mode, location and sync disabled, and other settings disabled. I did NOT restore any backups from Samsung or Google, nor installed any additional apps that did not come with the phone.
I have complained to Samsung through their Samsung Members application under Feedback. If you guys are on the same boat, I suggest we all start complaining so that they can start taking a look at this and hopefully release a fix.
If you guys have any tips or anything has worked for you guys, please let me know.

If its still draining that much even in flight mode, then something is definitely wrong. Seems like you've tried everything. Can you not get a replacement under warranty from where you purchased it? Sounds faulty.
Sent from my [device_name] using XDA-Developers Legacy app
I have had this same issue with my S7. Hence my reply. At that time I have traced it down to a certain kernel process. The only way to resolve this was to replace the motherboard. A factory reset didnt helped either.
Later when i investigated it further it was like an Interrupt request for sleep mode. Eleminating the phone going to deep sleep. Than you will see drains like this
My advice. Get the device replaced. It was the only way to resolve the problem on my S7. Hardware replacement

I installed BetterBatteryStats and got a ~20 drain over 9 hours of standby while sleeping. The phone was untouched for 9 hours, airplane mode on, location off, sync off, and other settings off.

Also, how did you manage to get your phone replaced? By Samsung? I am past the 30 day return policy so I am not sure how easy/hard it will be for the to replace my device/motherboard. What did you say to them exactly?
Reflash firmware?
Which update are you on?
After the ASCA, but before the finger print sensor update, I had amazing battery life, less than 1% per hour on idle.
But after finger print sensor update, it's about 2% per hour on idle.
Maybe reflash ASCA without the fps update? If it's possible

Spoke to someone in Reddit and he flashed his phone to the Febraury update. It still had bad idle drain.
Additional things I have tried recently overnight with no success
Disabled fingerprint
Removed SIM Card
Cleared memory cache again
I'll wait for the April update and see if that solves things. If not, I guess I'll drop by one of their service centers/genuis bars.
What a terrible experience...
Yeah that does not seem normal.
With airplane mode drop 0.2%/hours.
Sorry you are having bad issues. I would try to install U1 firmware and see if that helps.

I'm having the same issue after the recent updates on AT&T. I used to get close to 9 hours SOT and now I barely get 4. Nothing unusual in the battery stats either so I'm not sure what's going on.
Same here. The idle drain is completely insane! It's a shame that the phone suffers from issues like this when you compare it to the price we paid for it. From what I can tell the issue stems from the kernel not being able to figure out the proper frequencies for the cores in idle which leads to **** performance. I'm gonna try to flash the asd4 firmware via odin once. If it doesn't work I'm gonna get a replacement if possible. Currently I get around 4 hours of sot no matter what I do. Doesn't matter what I do which is super weird. My s7 edge which was at least 2 years old gave me a better sot more regularly, so I'm definitely pretty irritated with this. Will update once I flash over odin.

To all who has this issues. First thing to check is .. Does the phone ever enters deep sleep ....
I used this app on my S7..
Wakelock Detector. Can be found in google play.. Sorry cant post links due to my new status here.
Znalazłem rozwiązanie szybkiego rozładowania bateri zwłaszcza jak telefon noszony jest w kieszeni. W moim przypadku telefon przez noc zużywa jakiś 3% bateri a po włożeniu do kieszeni w 2 godziny 15% do wczoraj. A teraz Rozwiazanie . Wychodzimy w MENU - ZAAWANSOWANE FUNKCJE - RUCH I GESTY* - i odznaczamy opcję DOTKNIJ DWUKROTNIE ABY WYBUDZIĆ. następnie w MENU - EKRAN BLOKADY - ALWAYS ON DISPLAY - TRYB WYŚWIETLACZA zmieniamy opcję DOTKNIJ ABY POKAZAĆ na którąś z pozostałych lub całkowicie wyłączamy ALWAYS ON DISPLAY . To powinno rozwiązać problem z baterią w moim przypadku kończąc**pracę**z telefonem w kieszeni po 8 godzinach miałem 30% Baterii a teraz 70% .

BetterBatteryStats shows it goes to deep sleep 99% of the time overnight. No abnormal kernel wakelocks/partial wakelocks/alarms.
A couple of other things I have tried recently unsuccessfully while sleeping (6-8 hours) over the past week:
Safe Mode
Safe Mode + airplane mode
Safe Mode + airplane mode + cache wipe + Google services wipe
Safe Mode + airplane mode + cache wipe + Google services wipe + Remaining Apps in Sleep Mode (Battery Settings>Sleeping Apps)
Safe Mode + airplane mode + cache wipe + Google services wipe + Remaning Apps in Sleep Mode + Max Battery Mode (instead of Optimized Mode)
The best idle drain I got overnight was 15% drain over ~6 hours (~2.5%/hour)
I'll try disabling the Adaptive Battery/Auto Optimization while I have all my Apps in Sleep Mode an Safe Mode. I'll also try another Factory Reset this weekend.
If that doesn't work, I'll schedule an appointment with one of their service centers.
This sucks. My 2-year old S7 Edge still has better battery life than this.
I remember reading a post on Reddit from a guy saying he had a current leak on his faulty motherboard. Maybe you got the same issue on yours.

To my surprise the battery drain was still present. From 5PM to 730AM my battery went down from 87% to 60%!!! So about ~2%/hour while the S10 was COMPLETELY OFF.
I'll be taking my phone to the service center sometime this week. For anybody else having crazy drain problems, turn your device completely off and see if the drain is still present. It might be a hardware issue

Which update are you on?
After the ASCA, but before the finger print sensor update, I had amazing battery life, less than 1% per hour on idle.
But after finger print sensor update, it's about 2% per hour on idle.
Maybe reflash ASCA without the fps update? If it's possible
