Battery Drain On Amazon HD 8 - Fire HD 8 and HD 10 Q&A, Help & Troubleshooting

Recently purchased the Amazon HD 8 and thanks to everyone that contributes to this board (whom I would sincerely like to thank for all their hard work) was able to root and install Google Playstore. I subsequently installed ROMtoolbox Pro. I froze most of the Amazon apps that were running based on the list from a previous post that outlined what they found was safe to hide, or in my case, freeze.
While everything seems to work well (occasional freezes and unresponsiveness that I can live with as I assume its looking for an app or something that has been disabled) but what I can't live with is the battery drain. Its ridiculous. I saw in a previous thread that someone seemed to think Kingroot was the source of the battery drain. I actually have uninstalled Kingroot but I assume that the changes that it made are still running somewhere to maintain the root status.
Has anyone else experienced severe battery drain?

Well, I went ahead and restored to factory default. I re-rooted, used SuperSume to remove the kingroot install and used "hide" command to remove Amazon bloatware instead of using app dependent "freeze. It seems to be doing ok now. I passed on the nova launcher for now just to see how it does.
I'm betting it was Kingroot causing the extreme battery drain. I was down to 50% from 100% in 15 minutes of light web browsing and reddit app before I did all this.

[PSA] Removing bloat may make battery life *worse*

Just one data point, but it seems like a very clear takeaway:
I used titanium to uninstall a bunch of social apps, specifically anything including the words
facebook
twitter
flickr
instagram
linkedin
picasa
Importantly, I included any related apps (eg "Facebook Engine.." "Facebook for HTC Sense" etc)
I also uninstalled Car.. and HTC Car..
I found to my surprise that battery life got worse.
Much worse.
I ran the phone like this for two weeks and got somewhere between half and three-quarters of the battery performance during a normal day's use. A key observation is I went from losing 1-6% battery capacity overnight to losing 20% every night.
I restored a nandroid backup (returning the phone to its state immediately before removing these apps - - I made the nandroid for this reason and only this reason, and removing the social apps was the only change I made to the phone after making the nandroid) and my battery life immediately returned to normal. The last two nights since I made the change I lost only 2% battery life instead of 20.
Again, this is only one data point, and it's *possible* some other random thing happened in my world that could have caused this. But I really earnestly tried to be scientific (and patient) about this, and to me at least the result was very VERY clear.
Just leave the social apps, even if you don't use them.
[NB- I always remove 7digital, kidmode, rescue security, and I sometimes remove Chrome, and have never noticed an effect on battery life after removing those apps, over many months of owning the phone]
PS I don't have the paid version of TB, so no, I didn't freeze, I uninstalled outright and was forced to nandroid back to get to where I was before.
That sounds very strange!?
well, anyway, those apps, how much space are they taking from storage?
i feel i dont need to remove any apps, have plenty of room.
Just disable them under apps, and the hide the rest with whatever launcher you're using.
Battery life was fine for me (when I ran stock), and it's fine on my gf's one (who is currently still stock)
I remover app bloat all the time and get better battery. Are your sure your not doing it wrong?

Just selected the app in Titanium and clicked "uninstall". You tell me - is that doing it wrong?
I don't think this so much about *how* to uninstall an app but rather *whether* to uninstall an app that other parts of the whole system are expecting to be there.

Usually bloatware is installed as a system app. Sometimes when you uninstall them you can get some weird wakelocks or FC's. I usually freeze the app. Delete all data then uninstall.

This is true. Get an app like BetterBatteryStats and it will tell you if there is anything causing excessive drain. I have personally never experienced worse battery life after installing social apps.
That's crazy talk. Its definitely all in your head...
Experienced similar thing too. Tried several "debloated" ROMs like Trickdroid, Orio, few others (both when they were 4.2 and now leaked 4.3) and had an awful battery life. Went back to 4.2.2 stock (2.24.401.8) and now I can use my phone throughout the day again.
Well, what's being discussed here is taking a virgin stock ROM that has been running happily for some time and then using titanium to uninstall all the social apps at once: this method may cause wakelocks.
A ROM that has had all the "bloat" removed in advance before you even flash it seems less likely to leave your phone in such a state?
I'm not saying your experience is not real, and it raises an interesting point, but it still seems to me if bad battery life were common to all those debloated ROMs, I think we'd have heard more about it by now?
The right way to really test this, which was suggested above and I'm sorry I didn't do, is install BBS or GSAM and find out *what* is eating battery.
All I know is
- I changed X
- Things got worse
- I undid X
- Things got better

Now to test again remove the bloat again and see what the battery life does. But it's good you actually did some testing unlike the people calling you crazy but if your battery life decreases again after repeating the experiment the results are much stronger.
i remove all bloat that i would never use and my battery is fine
When I was stock, I froze everything that I considered to be bloat. I typically don't uninstalled system components. There's always a chance of borking something by uninstalling something you shouldn't have.

I'll uninstall carrier apps, because those are added after the fact. Uninstalling system apps can definitely cause issues. Better to hide them like someone suggested.

[Q] G2 VZW 442 stock rom terrible battery life for past month or so

Hey guys, I've had my VZW G2 since Feb and could not imagine being any happier with a phone. It's been completely perfect up until about a month ago.
I've been running official KK 442 since close to release. I tether a Pebble Steel daily. Phone is rooted and xposed with G2 Tweaksbox, GravityBox (KK),XBlast, and XuiMod as the main xposed mods installed.
Apps commonly used:
Facebook
FB Messenger
Poweramp
Chrome
Opera
Spotify
BleacherReport
Yahoo Fantasy
Light Flow
Sync (bit torrent Sync- just started using it well after battery issues started)
Pocket Casts
Mint
Pebble app (always latest from Play Store)
Various pebble apps like MusicBoss and PebbleLocker
Running this set up, i used to EASILY get at least 30+ hours battery life, with most days above 40+. That's being tethered to my watch for 9 hours. I didnt even have a charger at work because id be at 75% by the end of the day and would get an entire second work day out of the same charge.
Then one day I woke up and havent been able to get better than 25, with many days barely making 12-18. My battery life has been effectively halved and I can't figure out why. I'm constantly playing with settings or installing new apps, so I reverted any and all possible changes I'd made and froze all recently installed/new apps. When this didn't fix the problem, I started uninstalling and freezing apps that had been updated recently in the Play Store. When that didn't work, i took more drastic measures:
Things I've done:
FDR device, including wiping all data in TWRP and turning off google's app data sync to ensure fresh settings/config files
Uninstalled or used TitaniumBackup to freeze 40+ apps, including all non-necessary apps often considered to be battery hogs (fb+messenger, for example)
Froze Xposed and disabled all mods to run almost completely stock ROM with largely default settings
Monitored GSAM, BetterBatteryStats, Wakelock Detector, and CPU Spy for rogue/borked apps
Skipped wearing Pebble for a day to test
Updated and downgraded Google Play Services (various versions from as old as this past spring to the latest version released last week)
Prayed to Joe Pesci
Has anyone heard or seen ANYTHING that could be causing massive battery life losses but that doesn't show up as an app with massive wakelocks? Google Play Services has tons of wakelocks, but it always has. It's a known battery hog, but additional WLs and battery consumption are now expected with Google consolidating more and more services into it, so I'm not sure what to expect now. I dont use Hangouts but keep it installed and frozen 99.9999% of the time.
Not sure what else to do at this point.
still having major battery life issues. I've fdr twice and ran stock with minimal apps for a day with very little change.
guess my battery is bad. ugh.
is it worth replacing myself or should I try and get vzw or lg to replace it under standard warranty?

GSAM Battery App not working correctly?

Hey All,
After getting my nexus 6p, i added pure nexus/xposed/root on it. However, for whatever reason my GSAM app just doesn't work even with the root. See screenshot for what is happening.
http://imgur.com/4TF1HuA
I had the same issue. Seems to be related to the root companion app.
http://forum.xda-developers.com/showpost.php?p=63653215&postcount=201 (this post and a few after it)
I was able to get it working (actually showing percents instead of broken variables) by clearing cache and dalvik and installing the main app only. If I installed the root helper, the whole app lags and doesn't show any data. Unfortunately, without the root app you can't see wakelocks and detailed app stats, so I switched to BetterBatteryStats. Hoping GSAM gets fixed though, because I liked it better.
I installed and reinstalled like 3 times and finally got it working, i feel like it's random since i didnt have root companion installed
Try using BetterBatteryStats instead, it's a better app anyway.
I've had issues with gsam wake locking my device

Battery drain after Google Play installation

Hello,
I installed Google Play on my HDX (without rooting, since I can't yet) and noticed right away that the battery drains much faster. I had also installed an alternate launcher and the device seemed slow, so I factory reset the HDX and installed just Google Play again. Again the battery is drain is noticeably faster. Has anyone else experienced this and is there a way to mitigate it?
Thank you.
I have not experienced that but I have an hd10. Not an hdx
This is not the right fourm section for the HDX, however I do not see why your battery would drain after installing the Play Store.
Check your running services and processes, and go ahead and post your CPU/RAM usage, maybe Google Play Services is draining your battery.

(Qualcomm varient, I believe) [XT1768] Moto E4 - abnormal CPU, very low battery

I apologise in advance if this has already been discussed elsewhere, because I have been unable to find said topic if it exists.
My problem:
I have a Moto E4, bought from Republic Wireless in 2017, shortly after its launch. Up until last week, I have had no serious problems with it. This last week, however, I suddenly have had 50% reduced battery runtime, in addition to noticably slower performance.
After some quick digging, I determined that the culprit is not an app, but the OS (battery stats under settings places "Android System" around 70% of the battery's usage). I installed a CPU monitoring app, and discovered that the CPU speed was stuck at the max 1.4 GHz (it never scaled down) with an idle utilization of 25%. Although I am unable to see the utilization of each of the 4 cores, I believe one of them is running a code loop. Restarts, and cache, app cleaning have had no effect thus far.
As I have done no more digging (I am on vacation and haven't had much time), I would like to know what next steps I should take. I have not performed a factory reset, but it is one of my next options for when I return home.
I do not want to root if I don't have to, but I know how to do so if it's absolutely required.
Thank you in advance, i know this post is lengthy...

A factory reset is probably the next step if you prefer not to root. Also try to identify the source with a monitoring app like BBS or GSAM (I prefer the latter). You'll need to grant a few extra permissions via ADB on an unrooted device to get the full picture. GSAM walks you through the procedure via the overflow (3 dot) menu. Good luck.
I installed GSAM, used my PC to enable permissions, and checked the app after awhile. Once again, it's showing "Android system" as the main CPU AND battery hog, at over 74.6%. I would attach a picture, if I could figure out how to do it... (Please tell me how, I feel dumb). But that's what I have done this far. When I get home, I'll work on factory resetting it.
However, I am still worried that a factory reset might not fix the problem, since it is with the Android system. If all else fails, would it be possible to reflash the OS? The phone shipped with Republic Wireless software, so I would need the ROM from them..... And I would probably have to ask them for it. But that is only if reset fails to fix my problem. Is a reflash even possible...?

If it's the 1768 then the retail firmware should be fine (I'd say preferable even). Unless you need that extra software that is.
After factory resetting my phone, I reinstalled everything. BUT, to my surprise, as soon as I installed Snapchat, the same problem BEGAN HAPPENING AGAIN. I used GSAM, expecting to see Snapchat this time. Yet, it still said Android System was hogging the battery.
So I uninstalled Snapchat.
Surprisingly, the problem ceased to exist.
To be sure, I reinstalled Snapchat. The problem appeared. Uninstalled, problem disappeared.
So it appears that a factory reset might not have been necessary, but I'm wondering what aspect of Snapchat was causing the core overload. Regardless, I am never using Snapchat again, until I hear word of this problem being looked into/fixed. (I did capture and send them a bug report, but that might be of no help regarding this situation)

Did you grant permissions (via ADB) to allow GSAM to disambiguate resource consumption on an unrooted device. Try using Greenify to rein in bad app behaviors. Works a treat on rooted devices and *should* be effective on user installed apps if unrooted.
I'll try that. And yes, despite using my laptop to give GSAM permissions, it only showed Android system as using the power. I'll install Snapchat, see if the problem appears again, open GSAM, and give it some time. I'll also install the other app and set that up too.
Between those two, I should be able to determine if Snapchat is causing this issue; and if so, what part is. (Phone is unrooted, because I don't want to void warranty (Motorola needs to give me the key to root, and I don't want to do THAT just yet) so we'll see what happens)
Okay. After extensive testing, the phone has finally "cooled down". Snapchat no longer hogs battery, and now I get more battery life than before this problem even began. I wonder if, somehow, somewhere, a system file became corrupted, instead of Snapchat causing the problem...
Whatever the cause, a full system reset forced the loop to break.
Now I'll use Snapchat (and every other app) with caution now... I have a CPU monitoring app running 24/7 (it uses almost no battery)
