[Q] My Battery Life - Screenshots

Hi guys, I know there's a lot of battery related threads lately, but I've not been able to find a solution or explanation for my problems.
So last night I put my phone on charge around 10pm and went to sleep, I got up to go for a whizz during the night and saw that the light was green, approx 2.30am, so I disconnected the charger and left the phone on my desk and went back to sleep.
When I got up this morning I was quite surprised to see that my battery was down to 38%. This is the problem I've been having lately, rogue battery loss. I leave my "wi-fi on during sleep" set to never, and I believe the network was on 2g only (o2 UK), I'm running the Viper rom, with Nova Launcher and the Faux Kernel, not o/c or anything.
This is not the first time it's happened, so my question is, from looking at the screenshots, can anybody see an obvious culprit for the drain?
Thanks in advance.

Yeahp it's quite obvious that it's the android OS ... Some app is causing it to be awake ...

Yea I gathered that much, but what's the best way of narrowing it down? I've noticed in some other threads the guys have been asking for screenshots from better battery stats to help identify the problem. Did you see anything in what I posted?

try full a wipe of your system and then see the result.
If its working fine then install app one by one and see which app is causing the problem?

[Q] ROM CM 10.1 Battery Consumption

Guys,
Have you noticed huge battery consumption with CM 10.1 Unofficial ROM on E-980? I used to get 2 complete days on stock, but now I have to recharge my phone every night, no exception.
The biggest battery hogger is Android OS which consumes more than 50%. This is the original thread: http://forum.xda-developers.com/showthread.php?t=2387499&page=1.
Please let me know if any one of you have any solution.
Thanks!

Do yourself a favor and install Better Battery Stats. Then after a day of usage look into your Kernel Wake Locks and Partial Wake Locks. That'll give you a much better idea of what's draining your battery.

I just have installed it and will check it out in 24 hrs.
Meanwhile I wanted to know whether anyone else faced the same problem?

Quite a few of us had battery drain issues related to baseband. If you had installed the Value Pack update prior to installing CM you'd have the baseband which causes a lot of grief. Check the 10.1 thread. @madmack posted about what baseband you should have installed to stop the deep sleep issues.

Worked!

WOW, Thanks for your tip! As you suggested, I installed the model, and my phone is back to normal in battery consumption. Thanks!
I didn't notice this earlier, but my video recording doesn't work. Photos are coming properly, but as soon as I start shooting a video, my camera hangs. Even if I close it, I can't start it again until I restart my phone.
Can someone please help me?

Bad Battery Life since KitKat

Hi Guys,
i have a bit of a problem with the battery in my GNex maguro.
I'm an avid Rom flasher, but when i have something that works well i usually settle with it for a while. So i flashed Cataclysm (http://forum.xda-developers.com/showthread.php?t=1995801) sometime in the last months and it was running great. Best bettery life i had so far.
Then with the release of Android 4.4 i looked for a rom to test it. I flashed XP (http://forum.xda-developers.com/showthread.php?t=2539201) and i really like the 4.4 changes.
But since then my battery won't even last a day in standby mode. I thought maybe it's an issue with 4.4. still, but even after flashing back to Cataclysm (newest release) i still had the same issues. I thought it may well be, that the final version isn't what it used to be, so i flashed another rom again. This time Purity (http://forum.xda-developers.com/showthread.php?t=2012706) aaaand... still the same problem. So now i'm pretty much lost. I also tried different kernels (lean kernel specifically) but to no avail.
My battery used to last 2+ days in idle mode. Now i can see my battery drop every minute. It barely holds over 10 hours. I already did a full phone wipe and flashed back to stock before installing cataclysm again but still no improvement.
I hope someone can help me here or point in the right direction.
Sorry if this topic already exists, but the search funtion doesn't seem to work right now and google didn't show something helpfull.
Thank you all in advance.

I don't know why you would still have bad battery life moving back to the original rom you used but.. on 4.4 it is most likely the new Google Now features that constantly listen for voice commands. Disable it by long pressing on an empty part of the home screen and go to settings. Slide Google Now Off and go to voice and turn off hotword detection as well.
I get great standby battery life on 4.4. I'm running the 11/29 ART build of cmetal(toro), 150ish hours of uptime without any issues so far.

Re: Bad Battery Life since KK
What kernel are you running? Are you just using whatever kernels come with each ROM?

I'll try turning off google now and the voice stuff and report back.
It still seems really weird to me, that the problem still persists after flashing back to 4.3. My guess would be, that 4.4 flashes something hidden that messes with the battery. But i don't know where or what.
Especially since it persists after a complete wipe (/data, /system and /cache).
Well, i'll see how it behaves without google now.

Well i used mostly lean Kernel with 4.3 roms but i can't find any 4.4 kerneles besides CM. I have XP installed right know which uses CM Kernel.

Re:Bad Battery
Make sure your governor is set to interactive or ondemand...it could be seeing power drain from being set to one of the performance settings.
It's also possible that your battery is just going bad...do you have a backup battery you can try?

It could just be that you need to replace your battery. They are only good for so many charges and do degrade.

Reporting back. After deactivating google now yesterday my battery is still ****. It's at 50% after 2h idle and 30 minutes screentime. Before the 4.4 flash it would be at around ~85-90% now. I suspect that 4.4 flashes something in some hidden partition that i don't have access to, that messes with the battery. Users on other boards report the same issues as i have.

Just checked. Governor is set to interactive. It's also the default setting.
I sadly don't have a backup battery.

Could be, of course. But it's kinda weird that the decline is so dramatic and it has to be a pretty big coincidence that it just happend after a 4.4 flash. Seems unlikely to me.
edit: I'll order a new battery just to eliminate the battery as the source of error.

Same problem here. Since I flashed Kitkat on my phone, battery life isn't enough to last a day on standby. I tried installing another kernel (ASKP) but to no avail. Please keep in mind that I'm not very experienced with custom roms and rooting my phone. Does anyone have some good tips to improve battery life?

Update: After fiddling around a bit with better battery stats, greenify and a bunch of other stuff... i still don't have a solution. I made some screenshots of my stats, but can't post them here because i don't have permission to do that...

So i reflashed swordrune's cm11 rom and it seems to be working better with 1080p kernel w/o art enabled. i'm 11 hrs in with 80% battery on the extended battery (toro btw)

are u sure greenify didnt helping??? already got rooted & exposed installer running??
can u state your screen on time??
usually gnex can handle 3-4 hour screen on depend on battery condition n phone performance... not include idle n stanby time.

if u lightweight user, i suggest u to optimized performance. use apps such trickster mod, rom toolbox, or in addition of any light battery saving apps ( for optimization)
should be improve on screen time.

Not to hijack your thread, but I'm also experiencing battery issues after flashing the XP 4.4 rom. I did enjoy it but the battery drain was terrible. Not only that, for some reason my charger drains on a 1A charger but charges slowly on a .7A somehow. I only have 1 micro usb cable so I can't test if it's the cable and I can't find any apps to check the current speed. I tried downgrading and flashing to Slimbean but so far it's been no dice.

Ok, back again. hibernated every app and system-app that was running in background. Still wasn't getting better. I then saw the only services still running are google location services. I deactivated them now to see if these are causing it.
The biggest wakelocks i have are "wlan_rx_wake" which seem to be a known problem with KK:
http://forum.xda-developers.com/showthread.php?t=2519294
I then researched again and found several threads in google groups which describe the same problems that i have. Across several devices (though mostly Nexus 4, 5 and 7).
Google seems to be aware of that issue and is working on it.

Yes, same for me. Charging is really slow since 4.4 as is the bootprocess of my phone. From the first vibrate when switching the phone on it takes ~10 seconds until the google logo pops up.

i dont know any about gapps issues bcoz not running any gapps in my phone since last year.
1. try searching for updated radio.img (baseband/ radio) if got any network issue.
2. try install trickster mod app. this app can help you for tweaking into deep sleep, also help for optimizing.

[Q] [ARHD] Battery Drain

Hello guys,
I'm in a little trouble right now. For past two weeks I'm experiencing high battery drain on my HTC M8. I'm running Android Revolution HD 10.2 for three months and I've never had that much battery drain as I'm having now. For example, I unplug charger in the morning after all night charging and after 45 minutes (screen off, lte off, WiFi, bt and stuff also off) I have left only 92 % of battery.
What can I do? I appreciate any help and I'm ready to post all data you need.
Best regards,
pablo7890

Since you've been on the same ROM for 3 months, I suspect its some app or mod that you applied recently.
Otherwise it has to be a hardware issue.

I finally found out that Snapchat was draining battery as hell. I deleted it, but still it's draining badly. What can I do? Are there some good power saving tweaks or something?
Thanks

It will suck but your going to have to go app/mod by app/mod youve installed to find the culprit.

After you install the app, you can try disabling the tweaks that you have installed for a day or two to see how the battery goes. If its still bad, take a look at the wakelocks that's causing the issue. Or you can go for a full wipe and set-up your device from scratch without tweaks to see how the battery fares.

Nougat battery drain

Okay so, I flashed the latest Resurrection Remix yesterday, great performance ; however, there's a weird battery drain occurring to me. I've already tried multiple guides using greenify, amplify, etc but none really worked. I was using Viperrom 5.10 and wanted to revert back to complete stock after noticing random restarts and this battery drain. I installed stock through twrp with the backup I had before flashing and rooting then installed the stock recovery but still there was a battery drain. I flashed Leedroid, PureFusion 7.1.2 and still same problem. I think this is caused by something in Nougat since all the ROMs I flashed were nougat and showed the same issue. Now, I've seen many people experience the same problem but no one found a proper solution. Any insight as to whatever causes this battery drain would be appreciated. I'm not a heavy user at all; I don't have any games and all my apps are basically just social media like Telegram, Whatsapp, Youtube, Instagram and get barely 2.5hrs of SoT. Something to note too, my phone reports illogical battery percentages and sometimes shuts down when less than 50~40% due to an empty battery. For example, I restarted my phone a few minutes ago and upon booting it was 98% from full charge then I rebooted again and it's 78%.I'm not sure if this is a faulty battery or something wrong with the calibration. I tried calibrating multiple times but still nothing. I never abused my battery and most times I charged my phone before it hit 10-20%. Also one more question, I've noticed that on PureFusion the charging amperage was around 2-2.8 amps but on RR it reports 1.7 amps so is quick charge enabled on this ROM and if not what are the kernels I can flash to get QC? I've tried flashing Elemental X but it gets me stuck on the HTC splash screen.
I admit I'm kind of a noob when it comes to reporting bugs or issues, and I'm sorry for the length.
I'll add better screenshots of my stats after I collect more data.

I, and a lot of others, have suffered from the same symptoms. I thought I was alone but there is a big thread here https://forum.xda-developers.com/htc-10/help/random-shut-boot-loops-t3690547. I have got a support ticket (which is probably soon to expire, whoops!) but I've currently got it stuck in a bootloop at HTC (white) screen. Is this what yours did? Can you help me out?

No, my phone simply stays on the black screen with HTC logo in the center and the red text under it. Idk why it does that after flashing the kernel, probably not compatible idk,but what works with me is flashing the ROM again without messing with anything else.

Fixed mine, thanks. Just reflashed a stock rom I found on here. Wish I could help you more, but I think you might have to just return it unfortunately mate

I bought mine from another country and no international warranty so :/
I'd appreciate it if anyone replied to this thread. My phone is really unusable and disabling everything makes it useless and doesn't even save that much battery. My last resort would be to replace the battery but we all know how that would turn out and how it happens .
I tried :
1.Factory resets.
2.Flashed Viperrom,Leedroid,Purefusion 7.1.2,Resurrection Remix.
3.Flashed kernels like Cleanslate,Helix
4.Used battery saving apps like Greenify, Amplify, ForceDoze.
5.Disabled location, wifi, sync, cleared cache , reset app prefences, etc...
6.Started phone in safe mode.
Took all these steps and literally no significant improvement. I can't pinpoint an exact reason as to why I'm getting this drain but I noticed a lot of usage in GSam made by Android OS and in BBS and Wakelock detector PowerManagerService.Wakelocks seems to be on top of usage, and *launch* and *alarm* also have a very high number of wakelocks +1000 or even +10000. I've read on another thread that it might be wifi issue staying awake all the time. If someone has a good app to recommend me to monitor exactly and record whats draining I'll be eternally grateful .

Just a quick update.
I collected some stats. Not much but i saw some errors in there maybe some make some sense of them?
Mainly errors that are about Batterystats service: No controller energy info supplied and Power HAL : Failed to acquire lock whenever i touch the screen
I'll collect more logs and screenshots overnight in a +6hr period.

I found no solution except a battery replacement i can say it was definitely the battery. However, the drain is somewhat higher than it should be on Oreo.
