[Q] Can S-Off; Root affect battery life? - Verizon HTC One (M8)

Did the S-Off; Custom Recovery; Permanent Root last night. Everything went fine, rebooted after everything was done and charged my phone to 100%.
Wake up this morning after not touching the phone for 8 hours and the phone lost 30% over night. Looking at the battery stats the Kernel (Android OS) took up 60% of the battery. Wakelock Detector is showing Google Search as a wakeup trigger 92 times.
Before this whole process I was averaging 5-6 hours of screen on time, anybody else seeing some weirdness going on with their battery life?

Nothing abnormal here... Getting the same performance as I did pre s-off
M8, nuff said.

Root and S-Off alone? No. Mods/tweaks that require root? Yes.
Can Google search be a random wakelock sometimes for seemingly no reason? Absolutely.

Install gsam and get a better idea of whats going on. I also flashed the insecure kernel thats floating around and since actually noticing back to normal use.
Questions should go in Q/A btw

No I will look around for that though and see what it's about.

I've been rooting my phones since the Thunderbolt and I'm my opinion/experience nothing is better than stock. Once I started messing with Kernels, custom recoveries, Roms, "tweaks" ect...battery seems to be affected big time. Maybe its things I do as I'm not an expert at any of this and by no means am I trying to bash on devs for the work they do but that has just been my personal experience.

FWIW I didn't experience any sort of battery drain with the temp root before we got S-Off.

root and s-off will not affect battery. Xposed modules, root apps, and other mods can. I have about 6 or so xposed modules running and I still get way, way over 1.5 days of battery life. I had 2 hours of screen on time and my phone used 55% in 1.5 days so.... its pretty good. Check to make sure google now isnt causing wakelocks, turn off location reporting and if you can, turn off google now completely. I really only used it for weather because I don't see much other functionality with it.

I haven't added any apps since running the temp root when I was getting great battery life.
I did the s-off, recovery, and root...uninstalled Verizon bloat and that's it.
Lost 30% over night last night. I drained the battery to 1% last night, turned phone off and charged to 100%, unplugged and didn't touch it....woke up to 70% battery life.

Clearly you have wakelock issues. Get gsam battery and wakelock detector, post your stats after your phone is idle for a few hours.

I've had both of those running since the temp. root. which screens will give you the best idea of what is going on?
I did flash the insecure kernel earlier this afternoon, and turned off google now.

If anything try a factory reset. It should definitely help.

Post the gsam home screen and the apps section. Also post the home screen of wakelock detector for kernel wakelocks

Most s-off will turn on debug process.
return s on state after you have done modes or you need many tweaks in further.

Which one has the best life?

Gummy 1.9 EP1Q?
If i am getting %12-15 drain per hour while totally idle with 4g, wifi, bluetooth, and GPS disabled on Gummy 2.0 (base with no other software installed/running) is it worth taking to verizon (flashed to stock ee4) and try to get a replacement battery or something?

First off this should probably be in Q&A...
Secondly whoa there buddy thats a ton of drain with nothing activated or running, I get about 10-12% drain when I'm using it heavily. Have you tried calibrating your battery? There's a neat thread here in the general section somewhere like the 13 steps to a calibrated battery... After that you might wanna try downloading SetCPU or Voltage Control from the market and messing with some undervolting. If all that fails maybe you could try flashing the EP1Q modems in Odin, they're supposed to really reduce the 4G/3G/1x 'handoff' that drains battery. Worst case if you don't see any improvement then yes maybe flash back to stock and see if VZ will give you a new battery
You should keep your charge charged because charging it will keep it on.

Hardy harr.
Anyway, I had this exact issue when I first flashed Gummy2.0. When you flash a new ROM your battery stats are messed up(they aren't used to the new ROM) and cause MAJOR drain. My phone died in 6 hours in light usage on the first day of flashing it(as opposed to the 23+ hours of light I usually get). Also, the new kernel included in Gummy2.0 doesn't help with the battery stats either. A very simple fix to this is to just Calibrate your battery. Download the Battery Calibration app from the Android Market which will make calibrating a lot easier.
You can also try Undervolting(use the Voltage Control app) and lowering your brightness(use the Screen Filter app and set your brightness to like 70% and it will give you a boost in battery life). Aside from those tips there's nothing else to say, as Kejar has told us; ROMs have almost nothing to do with battery life. It's almost solely based on the kernel. Don't choose a ROM because you think it has better battery life. Just calibrate and you'll be fine.
Screen filter does nothing for battery life itself. Lowering brightness will help but that is not always ideal. Do y'all happen to know what chip is used to control your display?

SO i forgot to mention i was losing 15% per hour Idle After doing a battery re-calibration and wiping battery stats - charging to 100 on, then again while off, then on then off etc. then drain to 0 then full charge with power off.
STILL i get 15% per hour drain. I have also NEVER made it a full day wihtout having to charge, even 23 hours of total idle with mobile data/gps/bluetooth/wifi totally off would not be possible.. on any RoM i ever had.

You should usually be able to tell if it's the battery by the above average heat signature it gives off. I had the same exact issue and swapped out a new battery no questions asked. It's actually more prevalent than you would think. They can ship you a new one express or you can go to a corporate store and switch it in person.
I'm now getting 18+ on "moderate" usage and 24+ on "light" usage.
In the end it wouldn't hurt to try.
Its funny you mention that. On the days when it REALLY drops fast the battery gets really hot even when its doing nothing. So would you advise that i go ask for a replacement?
Its unlikely its your battery. It could be but I suspect something rogue is draining it fast or cpu or gpu is rogue.

maybe there faking to make them self's look impressive and make us jealous?
i had a similar problem. i would suggest going into CWM and wipe everything then reflash gummy 2.0 also going over to rootzwiki and getting imoseyon's new kernel v. 1.2.1 and flashing that via cmw. then after you have done that, calibrate your battery. after doing all this i am now getting 15-20 hrs moderate use

Wipe data, wipe cache, wipe dalvik. U don't have to wipe but I think it would help its up to you. I would def. suggest reflashing gummy 2.0 and getting imoseyons most recent kernel over at rootzwiki.
He means wipe cache & dalvik cache. He might also want you to wipe your data/format but that will erase all your apps so be careful. I've already posted how to get phenomenal battery life in this thread, it's VERY simple. If it doesn't work for you then just try again, if it still doesn't then I can't help you.
And no, we're not just "saying" we can get 15 hours of moderate usage, if you can't make it through the day you are definitely doing something wrong.
It could make a difference with rom if a kernel is built into it. Otherwise rom itself has nothing to do with battery life.

Terrible Battery Life

I don't know how everyone else is getting 3-5 hours of on screen time. When my screen is on, I lose about 1 percent every 2 minutes it seems like. When I look at the app usage, the kernel and media are sucking the life out of the battery. I am really discouraged about this battery because my G2 would easily get 3.5+ hours of on screen time. So far, I am going to be lucky to get about an hour.

I have Gsam installed but sometimes it doesn't accurately record on screen time as it resets to 0. Also, today I unplugged my phone and the phone was thinking that the charger was still connected. As I said, Gsam reports that the Kernel is taking battery power.

Mine has terrible battery life
I am very much on the same page with you. I am on my 4th cycle.
Mine only last 14 hours with 3 hours of screen time. I don't understand how all these people are getting 5 to 6 hours of screen time.
I have both Better Battery Stat and GSam monitor and it shows Kernel is taking 50% and system is taking 6.2%
Just try with different kernals,good kernals would give exellent battery life
I would gladly take the battery problems to get rid of this brand new beast. It's too Frickin big.. I had g2 but sold it. Paid 700 for this att note 3...lol. straight talk on att towers to save on bills. But this thing may be the fastest latest greatest next to the new releases of '14 but I should have kept the g2...This is a tank. I'd swap for smaller phone in heartbeat. Might post cl ad

Are you in the right forum? This makes no sense.
I think it highly depends on what you're doing when screen is on. If you're playing games or using a lot of data, it can drain very quickly. If you're watching local videos or something, your battery would last a lot longer.
Im a beginner, xda said i must have 10 posts to do anything on xda so i was filling my posts..sorry friend....now i got 10 posts so im playing with n9005 rom section now
if you are rooted, install better battery stats (free on xda from the dev) to see the culprit.
clearly something is keeping the phone awake and hogging the cpu
So far today with only 10 minutes of screen on time and 45 minutes of playing a podcast through Bluetooth in my car the battery is down to 92%. This podcast was already downloaded and just playing from Dogcatcher. When I left I rebooted the phone right after pulling it off the charger. The phone is rooted and all Verizon apps are disabled. I see the android system at 40% and Google Services at 15% usage. Yesterday with only about 2 hours of screen on time I was down to 18% after 10 hours off the charger. I do not see any one app drawing power, it is always the android system it seems.
Edit: Using BetterbatteryStats I noticed that my phone has basically been awake the entire time it has been off the charger. Out of 2.5 hours it was in deep sleep for 10 minutes.
I don't get great battery life either. Nor do I get good game performance. Battery has went down 9% in less than 2 hours of idle. Just downloaded gsam the kernel use is the highest at 26+ percentage

Turning off Location Reporting made a HUGE difference to my battery life. I accidentally left my phone laying in bed next to me last night instead of plugged in, and it dropped maybe 5% over 6 hours.

I will try disabling location reporting. But I know with my Galaxy S3 I had this enabled and did not have battery issues.
I turned off location reporting and location history and am seeing better battery life today. 5hrs 47 min and 89% battery left.
My battery is confusing me. First 2 days.. 15hrs 3hrs screen on time.. 3 days after that 24+hrs with 5hrs screen on time... The past couple of days I'm back down to 14-15hrs with 1-3hrs screen on time. This is running it down to 10%
My usage isn't much different from day to day.
Power saving is now enabled and I turned off location settings. Let's see...
M8, nuff said.
What I do not understand is why my old GS3 and my co-workers HTC One M7 with location services on, do not have this battery drain problem. This should not be an issue.
Yeah, it seems to be an on and off issue. On my GNex sometimes after flashing a ROM I had to turn location reporting off to get through the day, and then after the next ROM flash I didn't.

[Q] Way to find out why phone not deep sleeping?

I am running Skyfall with stock kernel. I was getting decent battery life, but today noticed that phone was awake for 2 of the 4 hours that it was off the charger. I have gsam and wake detector and wake detector shows nothing crazy that wakes it. I did disable location reporting, so maybe that might be pissing off some apps? I have not installed any new apps, only change was location reporting.
Thanks in advance.
Here is what I use,
https://play.google.com/store/apps/details?id=com.uzumapps.wakelockdetector
Works great for helping to find those pesky apps.

It seemed like it. I installed it while I still had BBS running. While I was running GSAM my awake time was about 2.5 hours out of just under 4 hrs total and the phone was just in my pocket most of the time. After I removed it and rebooted the awake time stayed proportional to the time I was actually using it. Other than turning on WiFi optimization I can't think of anything else I did. So it may have been either one but I didn't have WiFi optimization on before I installed GSAM and my battery life was okay.

I have tried with and without gsam. I flashed the lastest firmware and radios and also the snapdragon app that monitors your use and is supposed to save on battery and today I got 3 hours of SOT, off charger for 16 hours and still have 55% left. And wake time back down to normal use. Im about to flash the latest Skyfall so we will see how things go on that build.
So started getting bad wake locks again. I looked and saw media server using a good portion. I have 0 media on my phone as I just stream. Anyone else seeing this issue?

[Q] battery dropping significantly?

I've been using the latest ota 44s rooted, but with no modifications. its probably the most stable yet. no issues apart from this. despite the battery being actually quite good, i get 6+ sot within 40+ hours. but i'm getting an issue where according to the battery monitor, it drops a few percentages in one go without me actually using the device. its still on deep sleep. no wakelocks or anything like that.
Could it be that the battery stats is not being monitored properly by the phone? where the phone is going down steadily and then it realises the battery is at a slower percentage than its already displaying?
or is it something else?
This has happened to me several times previously. though no reboots, and battery life is still good.
as you can see here it drops from 86% to 77% whilst the -mAh is at -9mAH
Use a app such as better battery stats and debug your apps. There's most likely a app causing the phone not to properly deep sleep

Re: Phone deep sleep battery drain
I have also come across the sudden battery drain issue this past week. My phone deep sleeps well and I can find no wakelocks. It appears to use excessive battery when idle. I have tried a fresh, blank install of CM11S 44S and that didn't resolve the issue. I have since moved to Cm11 nightlies and that slowed the battery drain but I am losing 12% battery per hr when idle and the phone is staying warm. I do not understand how this happened and why it just spontaneously began. A fresh install with no additional apps, and no problems entering deep sleep. shouldn't be doing this This phone was brilliant for battery life and I cannot work out how to resolve this.

I have checked that and it appears to be sitting at the minimum 300MHz as far as I can tell. Since posting I have tried PA 4.6 for 24 hrs, no additional apps, and now I have moved to Liquid Smooth Lollipop nightly just to see how they compare. Even changing radios doesn't appear to have any impact on the power consumption.
When using GSam battery monitor on both the CM11 and PA (both behaved similarly) my phone was using anywhere from 500mA to 800mA (minimum screen brightness) for no apparent reason. I am unsure what usage this phone should be to be honest but I think that is high.
On Lillipop, the category 'Miscellaneous' is by far the greatest usage category and is seeing 2-3 times expected mAh drain compared to its computed usage, though I am unsure how that is worked out.
The most my phone will last now is 8hrs standby, in deep sleep. I am beginning to wonder if there is something wrong with the hardware of this device now. Perhaps the power regulator... Not sure what test to do next TBH
Thanks for your reply

When using GSam battery monitor on both the CM11 and PA (both behaved similarly) my phone was using anywhere from 500mA to 800mA (minimum screen brightness) for no apparent reason. I am unsure what usage this phone should be to be honest but I think that is high.
On Lillipop, the category 'Miscellaneous' is by far the greatest usage category and is seeing 2-3 times expected mAh drain compared to its computed usage, though I am unsure how that is worked out.
The most my phone will last now is 8hrs standby, in deep sleep. I am beginning to wonder if there is something wrong with the hardware of this device now. Perhaps the power regulator... Not sure what test to do next TBH
Thanks for your reply

The next thing I'd do would be a complete wipe and flashing the fastboot images. This still return the device to a completely stock state (including wiping the user data), leave it like that (don't install any apps) and test for a day or two.

Before flashing the CM11 Nightlies to see if they rectified the issue, I had downloaded and clean flashed the stock 44 image via fastboot but the issue remained. I shall re flash it though and post back...

Fresh install, data off and left to own devices for a few hours and it is deep sleeping like you would expect, but a neat linear drop in the battery of 10-12% per hour as before...
I saw the same type of behavior while running CM11 based ROM. At night, I would put device into sleep (no data/no wi-fi/no sync/etc.) - basically everything off. In the morning, it would still show 100% - but then quickly drain several percentage each minute for the first 10 or so minutes. It was like it was catching up to the correct %. I have used wakelock and BBS and nothing sticks out. I also set Google Play services to stop wake (which did help battery life a lot).

Does this battery drain make sense?

I was at home all day yesterday, I barely used my phone. I unplugged it in the morning around 6:00am, and battery was reported at 100% until about 10:00am. That can't be accurate because I made a couple calls and browsed around a bit.
From 10:00am, it discharged slowly to about 60%, when I went to bed at 9:00pm.
When I woke up at 6:00am this morning, the phone was totally drained and off. This doesn't make sense. Standby drain should be 2 or 3% an hour. not 60% over 9 hours.
Something is up...I'd greatly appreciate if anyone can help me solve this.
The battery on this phone doesn't seem to be calibrated all that well, so it is dropping faster than it appears to be when you unplug with a full charge. It doesn't really stay at 100% for 4 hours, so eventually it will start dropping faster once the phone realizes you are missing more battery than it thought.
With that said, you definitely seem to have had some process that bugged out and was running all night until the battery died. If that keeps happening I'd do a factory reset

thanks. I appreciate the answer. Any idea how to find that bugged process? All of the battery stat apps require root to identify this, which doesn't exist at the moment.

I don't know how to yet on unrooted 8.0. I don't know if the keyboard is considered a system app, but I lost 20% of my battery yesterday to Gboard so I wonder if that's also your problem. Mine did show up somewhere in the battery stats though so if you didn't see it there that's probably not your issue
Try Better Battery Stats (there's a good xda thread) and gsam (from the play store). If unrooted, you have to set some things with adb to get all functions.

There is root now that is definitely some rouge apps and or un calibrated battery hope u get it sorted out
I don't have this phone (yet), but isn't there a way to boot into the stock recovery/bootloader and wipe the battery stats there? or maybe an app that can do it that does NOT require root?
