Battery Life is Horrible on the T-Mobile Note 4 After Updating to Lollipop

Battery Life is Horrible After Updating to Lollipop, Its been only 4 hours and I went from 100% to 34%. Seriously, did T-Mobile upload the wrong update or are they expecting us to "upgrade" to an S6 / S6 Edge? I'm about hop on ODIN to revert back.

Seriously, :crying:

Battery life much improved, here.

^^^ Are you referring to the T-Mobile Note 4 or International?
Either I downgrade and wait for the next update which might take as little as two weeks to up to another 6 months, or I pay developers to get this sorted out, haha.

Never judge battery life after an OS update. You just flashed 15000 files or so. Come back in 4 days then we'll see what battery life really is. There's a lot going on under the hood after writing over 1 Gig of Code.

I cant say the same, battery looks just fine to me even that have passed only 24h from update. And was on full brightness 70% of the time On, and not to mention 1h30mins zynga poker.

If you're rooted, even after the update, you may need to get SE to Permissive. I did that previously when I had bad battery life on a stock (but Canadian) ROM and suddenly, magic.

It's odd that some say it's better and some say it's worse. For me battery life has gone down, not a huge amount, but a noticeable decrease. I'm all stock, not rooted.

Amazing despite all the warnings from the actual AOSP 5.01...all the warnings from sprint, verizon, and ATT users...we are STILL acting like this is some huge surprise and blaming Tmobile...

Never able to achieve 4 hrs sot

Our predictions came to life. Endless bug threads. Most of which are user error. And only one day or even a few hours of use. Sigh. O well

I tried Canadian port and my battery life was way better than KitKat. So far TMo Lolli seems just as good. I am very happy with Lollipop battery life.

38 hours of battery
Mine seems to be working incredibly well, even better than it was on Firekat. I have had it on for 10 hours and it says I still have 1 day 3 hours left.
Steps I took
Updated
Factory Reset
Set up as new device
Formated SD
Rooted and installed TWRP
Setup Greenify
Success

I had terrible battery life when I updated my Note 3 to Lollipop. Tried every trick listed on the Internet. Finally did a factory reset and everything was perfect. Did that from the get-go with my Note 4 and battery life after Lollipop is great. I don't know why the OTA update seems to cause battery problems, but a factory reset was the answer for me, at least on the Note 3. It would be interesting to see how many of those with problems did an update without a reset.

Has anybody rooted the T-mobile S7 edge and actually kept it rooted?

A few days ago, I rooted my phone. My phone got hot and slow so I restored a stock image. Has anyone rooted their phone that actually uses it?
Did all those tutorials actually make the rooted phone worth using?

Been rooted for about close to 3 weeks now. Soon as i rooted, flashed TEKXV2 and all has been good so far. Never had an issue with phone not staying rooted. There are more than a few tweaks floating around that will definitely help improve things overall. But again, never had any type of issues staying rooted.
when you rooted, did you change the kernel governor to Interactive? That should have helped some with the phone getting hot.

It hasn't happened to me yet.

Just read all 80 pages of the how to root thread and then the post root problens thread. Everything you need is in there. Just seriously take the time to read and take notes and itll be the best rooted phone ever. Been a month for me. If you dont read it all people arent going to answer because of all the repetative questions that keep getting asked because of people not reading the existing info

The root on the s7 edge has been the best root for me so far and I've been rooting since the g1 days. If you follow all instructions you will have no problems. Use package disabled pro and turn off software update, there are 2, and you should be good with keeping root for as long as you want. I'm using viper and getting all day battery with tekhd ver2.

I'm running root on the stock ROM and so far so good. I have ViPER4Android + Dolby Atmos and things couldn't be better. The lag and heating issues lasted only for about the first 24 hours, after that battery life improved and the lag ceased a lot. Disable all the bloatware, set the cpu and you'll be fine.

I'm still rooted on stock PG9. After the first day, through heavy tweaking, I was able to get SOT above stock time. There is no lag, and benchmark numbers dropped by less than 2% due to the tweaks.

I have two S7 Edge phones. I rooted one last weekend and after a day, rooted the second one. Only the first one is still rooted today. I'm still not so sure I like the battery life on the rooted one. I changed the governor to on demand as was recommended by the OP in the root thread. After 17hrs standby, I have one hr screen time with 49% left to go. I average about 2-3 hrs on the non rooted phone with 1-2 days standby. I'll likely get less then two on the rooted one with just over a day of standby.
I seriously thought of going back to stock on the rooted one today but I'll hold out for a few more days.
I still have my Note 5, Note 4, Note Edge all rooted so I have plenty of toys to play with no matter what I do with the S7 Edge.

Use this guide - http://forum.xda-developers.com/ver...-to-notes-root-install-xposed-unroot-t3411039 - in the "recommended next steps", there is a flashable zip that corrects all the kernel issues. I've been running flawlessly with it, better battery life than my wife's unrooted S7E.

i've rooted mine and love it!

Other than the international S7 Edge of course. :angel:

Been on current rooted 935T since July 10 - no issues. Tried it earlier but did not factory reset first and had many issues including frequent reboots.

Are reports of battery drain after rooting real??

My s7 is arriving today and I was all set to root. But I keep reading posts about how the phone becomes super laggy with all types of battery drain.
I guess I'm trying to gauge if that's a real issue or people just overreacting.
If anyone can share their findings and thoughts I'd appreciate it.

If you follow all the steps after rooting it's not bad. Sot is not as good but standby time is the same for me. I also have no lag.

Follow swicks lag thread. When I first got my s7, I couldn't go more than 7 hours without having to charge it. First day with the tweaks in his thread. I got this

Look into the U firmware. It removes the Verizon bloat, stable, and great battery life!

You can fix idle time on stock by downloading ez disabler (Samsung) from the market and getting a XML list of everything to disable.

I rooted my SM-G930V, and I am experiencing some heat from the phone when it is sleeping- not so much when it is unlocked and operating.
As for battery drain- I have not noticed any major loss in battery usage.
There also seems to be a significant speed issue with speed- took around 5 seconds to open the settings app, But this can be fixed by
editing CPU governor from interactive to ondemand with Kernel Aduitor.
I am looking into this article to fix the heat issue: http://forum.xda-developers.com/ver...guide-to-fix-s7-lag-root-s7-variants-t3441715

Stang5litre rom and you wont regret it

You can do a lot with various Xposed modules and other root apps to mitigate the drain, but there is some drain nonetheless. SOT takes a bit of a hit. Standby time, it's negligible.

I recommened personally sticking to stock. I use to be rooted and between battery life and issues I went back to stock. This was before the roms came out. I have a new born and a family I can't play around with signal dropping, phone restarting, lagging and whatever else. I like stock with nougat beta. If the bootloader ever gets unlocked or something else that interests me to root maybe one day but not worth it for me right now.

With Stang5litre's rom I've have zero problems.

There is no way with any rom or any app (unless it is magical and brand new) that you aren't having issues with this phone and root. I tried every app I could and 2 roms available here for it as well and it was still laggy with terrible battery life. I held on with this phone as long as I could hoping for a better root method but I couldn't wait any more. The performance after a few apps and kernel changes is still terrible compared to stock. The battery life after fixes and kernel changes is equally as terrible. I was getting around 1 hour and 10 mins of SOT before it was completely dead. I loved the phone and stock it had great performance and battery life, but that eng kernel for root just destroys it. I NEED root on my phone or I would have kept it stock. Word of advise, keep this phone stock or sell it and get something that can be rooted and actually stay usable.

I get about 5-6 hours SOT and no performance issues. I occasionally overheat but that's it. Different people have different results, for whatever reason.

Battery life issues

I'm on the T-Mobile variant. My battery was amazing the first few days lasting anywhere from 6.6-7.5 hours of SOT. Now Im avereging 5-6 hours of SOT. A lot of Android OS and Android system drainage. I'm not rooted neither. Anyone else?

Did you take the 10i update?

Haven't received it yet. I checked yesterday for updates and nothing popped up. Did you get one?

This is what I have so far

I'm rooted so I'm on 10d for now.
I was hoping you had taken it, because that would've explained the battery. Honestly, though, even 5-6 hours seems like a ton. Maybe you installed something new? I'd recommend GSam, but that doesn't work on Nougat without root.

Screen time, depends on what your doing, and what your connection speed is.
Maybe Google featured apps? Also you may be doing things you weren't doing before on the phone.
Its hard to tell, I wouldn't say you have a drain issue based on previous screen time.
Now if you said, I was getting 6.5 before and now only getting 3 hours, than I'd say there's an issue.

Not sure if it applies. But I noticed some greater than usual battery drain right before my external speaker became all distorted. Since then I've noticed a marked decrease in battery especially standby. Hopefully that will change once I send it in and get it fixed.

Anyone still on Marshmallow?

I'm still on the last August build of PureNexus 6.0.1. Mainly because for some reason V4A works and processes everything whereas Nougat won't process SoundCloud, and xposed modules.
Who else is on MM?

I'm still on stock MM September build. I'm dubious to update after reading about the battery issues on Android 7.

Battery issues? What battery issues? I've been on Nougat for almost 3 months with no random shutdowns, unexplained drain, etc. With Google Now on, location on, and all sorts of other battery draining features enabled my phone routinely lasts 18+ hours with 5+ hours of SOT with 20% or more battery left. My 6P is only 3 months old, so my battery is still basically new, unlike most 6P's out there.
The "battery issues" you hear about are hardware faults, not Nougat issues. It's just a coincidence that they started popping up around the same time Nougat was released.

O Nougat since it came out. No problem whatsoever. Keep in mind the people having problem are little to none.

I was on Nougat for months, but I'm back on MTC20L (6.0.1).

What battery issues? I must have made that up then? Hardware fault, maybe. Coincidence that they appeared at the same time as Nougat, maybe.
My 6P is 12 months old next week, so there is a very good chance that I could be susceptible to the "non existent" battery issues with Nougat. Until I'm sure it is safe to upgrade (it was the same with my Nexus 4.,I delayed updgrading due to issues with updates for that) I'll upgrade.
If it ain't broke is my motto...

Well how can it exist if one doesn't experience it? The issue is the the rom is the easiest thing to blame when there isnt anything else to blame. I'd narrow it down to app + phone usage. Ive had my phone since it came out and the only issue is its non-functional in weather below 0c. Im using N, on AICP w/ Flash kernal and i exceed 4+ SOT on normal usage. With games its down to 2-3 hours depending on how long or intensive the game is.

If it was a wide spread problem that affected everyone on Nougat, then I should probably be experiencing it.
If you look at the random shutdown/bootloop threads almost everyone affected has had their phones since it came out, which means their batteries are old and worn out. Most of them have reported that replacing the battery/getting a new phone has fixed their issues, which further reinforces my hardware fault argument.
It's easy to blame Google and their software because no one wants to believe that their $500+ phone is defective, but the cold hard truth is it's not Nougat's fault.
This winter my Nexus 6 on Marshmallow started shutting down randomly in the cold, but is that the fault of the software? No. The battery was over 2 years old and had reached the end of its usable life.

I'm on marshmallow because of Xpose. ?

I'm about to go back to marshmallow. Tired of playing cat and mouse to get adfree YouTube. Suddenly I have ads again. Miss the good old days with the Xposed module to take care of that problem.
Gonna be weird going back, lol.

Went back to September build since it was the last one. Was never actually on mm before since I started updating to nougat immediately after getting the phone. Curious how Xposed would work on the 6p. Great, I'd have to say. I have the phone exactly how I want it. Changed the dpi to 640. No more squinting. Won't be upgrading unless Xposed is also working.
