Rooted Snapdragon Note8 Battery Life Discussion - Samsung Galaxy Note 8 Guides, News, & Discussion

I thought it might be helpful to have a thread devoted to this. Maybe people can post their battery stats, talk about how their battery life has been since root (anecdotally), etc. I know it's a big deal for many people considering root so it would possibly alleviate concerns if people discuss their experiences here.

I noticed that I burned through the battery quicker being rooted. I decided not to disable anything on the device in terms of bloat or apps that I don't use. I installed the same apps that I had on it before I rooted it but didn't do a backup restore to avoid any sort of conflicts. Used it for about a week rooted dodging work device compromise flags. I just wanted to see how much of an impact the 80% battery cap thing would have been. Although I am thankful for root, I realized that for me it is not needed at this present time and the battery hit isn't worth it.

I wonder if disabling and tweaking things via root capabilities could compensate for at least some of the loss. Some people have said they didn't notice any difference with the 80% cap and I'm wondering how.

To ROOT or NOT to Root, that is the question.

Coming from the DX, the benefits of rooting (even with it locked down) were WIFI tethering, screenshots, and overall just being able to customize the phone more with themes, colors, etc.
From what I can tell, the Wifi tethering app just can't hang with the native MobileHotSpot tethering option provided by the phone, in which case, it becomes less of a benefit.
I can see why people don't like Sense but it doesn't bother me one bit so that really isn't a factor. Just wondering what other features (or lack thereof) are pushing people one way or the other.
well i supposed it's up to you if you like to tinker or not. so far i am using the das bamf rom and really like it. for one, all the vzw bloat is gone, and there are a number of nice little features such as the battery charging icon, 5 icon wide app drawer, transparent app drawer/notifications.
root enables programs such as set cpu to control the cpu speed. for instance, i have the cpu slow way down when the screen is off saving battery.
if you are happy with your phone the way it is, leave it. if you like to play around, try new things, and have a better phone than the manufacturer came out with, root it. there is practically no danger and you can also go back to stock.
I just rooted because I hate all the bull**** bloatware. Also like to customize
The ability to remove the Verizon software off the phone (VVM, VZ Navigation, VZW Backup, etc) and the ability to change the DPI to something more usable (i.e., less big).
Those are my reasons...
Titanium Backup... Removal of bloatware... Those two things, even if you plan on keeping stock rom, is enough reason to root, in my opinion.

Are you referring to having to scroll through them when in the apps folder or actually feeling a performance difference by removing them? If it's scrolling past them, that doesn't much bother me..
Now that the kernel source is out, I'll definitely be rooting. Battery life is a top priority so undervolting is a big factor for me if nothing else.

who needs vz backup assistant when google does it for free? i guess some people can live with trialware taking up useless space but cityid is just awful. I use to get nag screens on my incredible. There is an option to remove it if you cancel the trail peroid, but it is still there taking up memory
My reasons that I rooted:
1. Get rid of bloatware
2. Get rid of bloatware
3. Customization options
4. *FULL* backups of my phone (Titanium Backup)
5. Overclocking, Underclocking, Overvolting and Undervolting
The Kernel was just released by HTC today, so we will be getting some really nice mods for the T-Bolt soon. Some of the things I want:
1. When my phone is plugged into a charger, I want it overvolted and overclocked for FULL performance (1.6ghz stable please )
2. When my phone is on battery, I want it back to 1ghz, but lets unvervolt it to get better battery.
3. When my phone's screen is locked lets underclock it down to 250mhz, seriously undervolt it, and get some real juice out of it.
4. When my phone's screen is locked, auto disable 4g, gps and wifi for even more battery savings.
Basically I want a phone that screams when it is supposed to scream, and tidy on the battery when it is supposed to be.
For me its about bloatware and speed. Plus (correct me if im wrong) the hotspot tethering is only free for a period of time, so eventually youll want that root for the tether.
I always equate it to if you buy a pc versus building it. Most people if they buy it the first thing they do is delete all the crap for overall performance.
Even if you root only to get rid of the bloatware your going to see an increase in battery life (especially from crappy blockbuster) and load speeds.

also read reports of blockbuster running in the background constantly updating and draining the battery unless you physically go in there and turn it off...i didnt bother checking that out, i promptly removed it for good
For me it was all about the customization. Everything I own I tweak to make it just to my like so the same goes for my phone, so rooting was just necessary. Also a lot of the custom ROMS are designed to help improve battery life, and since the battery life of the TB isn't very stellar to begin with, it is nice to be able to increase it by flashing the correct ROM. I really don't see a situation where you wouldn't want to root it.
My moto is when in doubt... Root.
It just makes it better
Had my Thunderbolt since day one. It's my first smartphone. I want to root it and in the process of doing so. I've read that it will wipe my phone. Just curious. Does that include my SD card as well? and how would i go about flashing my stock ROM just in case i need to take it in for warranty purposes?

It wont wipe your sd card unless you select it to in clockwork recovery.
to get back to out of the box with s-on and original rom. download this ruu and plug your phone in. http://forum.xda-developers.com/showthread.php?t=975888

Coming from the DX you were in a walled garden (not as bad as another walled garden, but walled none the less). While I do like Sense, there are also Cyanogen, Liquid Metal, and MIUI as examples of rom styles that will completely transform your phone.
MIUI menus for example are by far the best designed that I have seen. And you might reply who cares about menus, but once you have messed with it, it makes a world of difference.
Cyanogen adds a crap ton of function then tends to focus on stability. This lead to (IMHO) the smoothest most stable rom on the Droid Inc.
Liquid Metal is just way outside the box. I was not fond of it (except the kick ass lock screen), but I bet someone here who did fancy it could speak for its merits.
The real question is, why the hell wouldn't you root

I will most likely root, I guess I have just been pretty impressed with this phone stock, wasn't sure I needed it. Take into consideration more customization, tethering and increased battery life, again, I think it's a no-brainer.
Are you guys seeing an increase in speed and battery life now that you've rooted? I know killing bloatware also kills running services which should in theory help, but isn't undervolting the best way to maximize juice?

Rooting....

Nice to see the thread dealing with rooting, I am just wondering how the battery life is when rooted. I rooted my SG2 and it was great not having to worry about charging every 6 hrs, in fact I was getting well over a day.
I am thinking of rooting although this SG3 seems to be pretty good with the battery, hence my interest in how the battery is when rooted.
Thanks
sr
....well it really depends on what you do with the phone once rooted???
Rooting in itself will do NOTHING to change battery life, all it does is allow you to run apps that require root.
If you were to flash a new kernel or use root apps that adjust things like cpu speed etc then battery life can be affected, but otherwise it will act like an unrooted phone.

Horrible battery life on 1.58.502.1

Am I the only one? I just updated 3 days ago with RUU to the latest build. Before the update a full charge would last me about a day and a half with moderate use. Now with the new update I am lucky to last half a day without it going into Power Saving Mode, then about 2 hours later it will be in Extreme Power Saving Mode. Anyone else getting sh!tty battery life since the update?...

At the risk of sounding like a noob.... Whats ART?
Battery life is incredibly complex and elusive. Asking if other experience the same is all but useless. Reason being, such comparisons are just anecdotal and will often not apply to you. There are simply too many variables, such as how you use your phone, what apps, and often most important is reception in your local area. It could be that the new radio deployed with 1.58 simply does not play well in your area. The intent is to always be "improving" the radio software, but its the minority of cases where it actually gets worse, which can greatly affect battery life.
Also, I've seen a lot of cases where AT&T bloatware runs out of control and kills the battery. You might start by looking into this. There are various apps that allow you to accurately see what apps are using battery (in addition to the Usage in Settings). Lots of folks here seem to like Watchdog Task Manager.

Right I understand that, but what I'm really asking are those who updated to 1.58.502.1 from the older build, did you notice a decrease in battery life... Not trying to compare my battery life to someone elses, I get how that is an impossible answer.

How is asking if anyone is noticing decreased battery life after 1.58 any different from comparing battery life? Its the same thing.
I can guarantee that there are some people that have experienced worse battery life; and some have seen the same or better battery after 1.58 (as this has and will occur for any new OTA/RUU).
Not trying to be argumentative, but my point is whether folks have seen decreased battery life or not is somewhat irrelevant, and isn't going to solve your problem. Better to look into what processes are actually causing the drain, and go from there.
try booting into stock recovery and wiping cache partition...has helped some folks in past
I actually did what dudeluv said and am using ART now. Waaaaay better battery life, actually better than it was previously. Havnt ran into any bugs in it yet either. But we will see as time goes on.

Oh yeah, full charge yesterday, using it just as much as I normally would and when I plugged it before I went to be still had 86% battery life. Compared to being on 15% by 4 in the afternoon.

Battery life in Lollipop goes down?

Hey guys. Just saw this article stating that the G3 has less battery life with lollipop: http://www.techtimes.com/articles/3...alaxy-s5-htc-one-m8-nexus-5-lg-g3-results.htm
Are you guys running LP seeing a drop in battery like the article??
Im not on stock but I am on Lollipop and the battery life for me has been about the same. I feel like Google really dropped the ball with Lollipop as far as battery life is concerned... like they were talking up project volta and how it was supposed to make battery life 36% better on lollipop for certain devices. Yet most devices seem to be struggling to keep the battery life they had before the lollipop update. I know there is a lot of factors and development isn't necessarily going to be perfect with such a new release but still...
I get at least the same if not better battery use, for me typically 80+ hours before charging, my record, 124 hours.

One thing everyone must remember. Not all apps have been upgraded to utilize any new programming APIs, etc based on Lollipop. Lollipop under the hood is a different environment. No longer is Dalvik around. It's now ART. Some apps still do things that are only available under Dalvik, hence they do not work under LP.
Also, APIs go out of date, also known as deprecated, as OS'es mature. Apps that continue to use old, out-dated API calls, or were improperly programmed from the beginning but could get away with it in older versions of the Android OS, are now showing their issues. This can result in either the app not working at all, or the app could drain the battery.
Android apps are a different beast from your normal PC Windows application/program. They should not run in the background if minimized/when a user switches out. They usually go into a suspended mode so that they are not consuming resources. Out of the box, when an app is written, all of that handling is set up automatically. However, it can be circumvented due to someone not understanding the Android app life-cycle, or they know it and don't care, and just do poor programming. Either way can result in an app that misbehaves and drains the battery, as well as consuming resources (memory, CPU, etc). That also leads to battery drain.
So, I think part of this is Google, but I also believe that most of it is due to apps that are not optimized for Lollipop. I would like to see, or know, if these tests were run on straight stock with NO user downloaded apps. That would give us a clearer picture as to whether or not LP truly does gain better battery life for certain devices (I read that as newer devices).
No battery life difference for me.
Only difference I've noticed would be the stock LP gives better battery life than AOSP

Yeah I keep forgetting about the out of date API's but I practically use only Google Apps, I pretty much have everything I need on Google's platform. I only have a handful of apps that aren't google but I rarely use them. Still haven't noticed a change in battery. Not that the battery is bad per say my battery is actually pretty good especially compared to my S3 back in the day. Ive just been seeing other people complain in different forums. But you're right they are probably not using fully optimized apps for lollipop if they are having battery issues.

My wife and I aren't that popular, so we don't talk on the phone much. She does use hers a LOT for games. When we got our G3s, I picked up a Verizon LG G Tab 8.3 VK810.4G as well, so now I spare my phone battery a lot for music in the car, GPS, some gaming and quite a bit of TapaTalk or other web browsing. About the only time I do any of those on my phone is when I'm at work killing time sitting on the toilet, or waiting for my lunch to heat up in the microwave.
gosh one of the main reason i was going to upgrade to LP and reading this it doesn't seem worthwhile anymore. are there any reasons to upgrade to LP other than maybe material design? it seems sort to just be a ui makeover now...

ART instead of Dalvik. It's much smoother now.

Another thing to do is give it a few days after upgrading. At first, you might see poorer battery life but give it a few days and it might stabilize after that and you might see better battery life.
Also, once you've done this, start monitoring the battery section to see which apps are consuming the most battery life. This should give you an idea as to what is going on. That can help you pin point better misbehaving apps.
Also, I use the Snap Dragon Battery Guru app. That can also help pinpoint apps that might not be behaving correctly, plus it can do some managing of things to help preserve battery life. Not sure how much it helps, but it hasn't hurt, so I continue to use it.
Just some helpful hints that I've observed with this phone. I used to use Greenify, but I have found that I can get just about the same battery life without it as I did with it (at least on this phone), so I've since removed it. But, it's still an option to look at it, and it doesn't require root any more, which is nice for those that don't wish to root. And it has helped me in the past with other phones. I just haven't found that it helps that much with this phone.

Note that stock LG Lollipop builds 23A & 23B result in the SnapDragon Battery Guru app claiming it's incompatible when you go to it's Play Store page, although I haven't tried sideloading/restoring it from Titanium Backup.

Ahh. Since I haven't upgrade to LP (still on stock and happy as a clam), this is good to know.
Battery life does not change whatsoever. The display is always the culprit. Can get 5hrs of screen time sometimes 6 per stock battery.

Which is why I believe, as I stated earlier, this points to misbehaving apps that are not "tuned" correctly for LP. It's always better to just wipe clean (FDR) and then start restoring apps one by one to see what might be causing it. But also, give it a few days to settle down too.
I'm still waiting for the "official" release and then, will wait to see if either root can carry forward or else, the latest root still works on the official release.
T-Mobile users can now upgrade via the software tool on their Windows machines (not available as an OTA yet for them). Seeing how the G2 is getting it already, I have to imagine the G3 is not far behind. I'd much rather they just give us 5.1 to fix the memory leak.
I have noticed much better battery life on 23B Lollipop. I'm not rooted or anything, but for example I can listen to Audible for my daily drive into work that takes me 1.5 hours and the battery will only drop to 99%. I got 23B following another thread here, but my wife got a replacement G3 and it offered the update to 23b before the SIM card or SD card had been put in the phone. My son has a G2 that got the official Lollipop and it actually required two updates to get there. 1 just installed some system prereqs.
I'm in stock 23c and battery life is the same as it was under kk which for me is a good thing as I got excellent battery life under 12b. I'm not rooted because I want to wait and see if/when another ota comes out to fix the Wi-Fi sync issue.
I just finally updated to 23c. Seems wifi works fine for me thus far. I'll see how battery life is tomorrow after a full charge /discharge. Everything seems pretty snappy so far. I didn't even do a factory reset. Hopefully I won't have too.

Still running on original firmware. Time to finally update?

Ever since Samsung carrier specific phones have been becoming increasingly more difficult to root, the very first thing I do on my last 3 or 4 Samsung phones is get the package disabler to prevent any updates and notifications for updates. In hopes of getting root/custom recovery or maybe even magically unlock the bootloader asap, and don't want to accidentally download a patch the could prevent me from having the option. I am still running N950USQU1AQH7. I was wondering anyones opinions on weather or not I should just cave in finally now and accept that I won't be able to ever run root/xposed in the future of this phone.
I know we have that 80% battery root option, but I really would use that for Titanium Backup and possibly Greenify. Plus the 80 percent thing would drive my OCD nuts, even if if there is a visual only fix.
So I guess I'm asking, are there any significant benefits to finally updating my phone/firmware/moving on to 8.0? Or do you think there still may be a shred of hope for me?
I'm not really having any issues with my phone except for the bloatwares/Bixby junk I have disabled already.
hows your battery life so far??? I feel like oreo has made the battery drain quicker, but at the same time I have am a heavy user. I do alot of recording and editing on my device and I factory reset after updates. I remember when it would report 40 hrs of battery life, now I get 18 hrs.
I know its only a year old, but kind of a quick drop for a phone that was released at 1k
