Hey guys I have a att g935a upgraded to android nougat 7.0. I feel like my phone battery really sucks. From about 7am-11am it dropped 30% is that good? I personally think that's bad. Here is my day stats with charge. Should I go back to stock firmware and downgrade and factory reset? Or should I stick with this
Battery life with rooted/modded AT&T software was always very spotty for me. Sometimes it would go all day just fine with no problems and I'd get home in the 80% range. Other days it would drop like a rock. Every great once in a while, I would pull my phone out and it would be very hot and have drained the battery badly for no apparent reason, so I gave up on root.
However, I believe a lot of that is on AT&T. My phone has performed like a whole new device since I converted to the carrier-free U firmware. It is hard to understate what a difference it has made, and I believe a lot of what I attributed to the the root solution was actually just AT&T's bloat.

I would first look at what apps are running in the background. Close any apps not being used.

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.
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.
Hi,
I have been using this phone for a year now. I really feel we got more preformance after oreo. The phone is pretty smooth after all the hassle. I do think we lost a bit screen on time with the os update. I feel that is many times the price of getting more speed. Anyway i tried for a while my G4 rooted + optimized. My conclusion is that optimized + sabs and non rooted s7 edge is really fast phone. I see no lag. I feel this phone has a year left in it and thats actually impressive knowing its 2,5 years old.
I tried Oreo without factory reset. My experience was that some of the apps did not function well. So i did the factory reset and all works now. I think its only smart move after os update. Now i will just clear system cache after minor fixes.
The last as good deal was lg g2 to me. Love your phone still its in the competition with never phones. After year i bet we see improvements that will make many of us consider changing to a next generation of phones.
Btw. Did anyone else get the stability update after oreo? What do you guys think of it? My feel is that now almost 100% is working and smooth as a butter.
Model: SM-G935F, Exynos
You need to specify what version of the phone you actually have.
Thanks for the comment.
I edited the first post to give the model of my phone

I have moved back to nougat and stayed there for now, i did not mind the cell drain as it still lasted me all day, however i had random reboots as soon as i moved to official Oreo or even custom rom with 8.0 base, did not matter what i did the reboots would get worse over time. I moved back to nougat and not one reboot experienced, Oreo for me is good when it worked and would love to use it but drove me crackers when rebooting. SM-G935F

This is actually intresting. My phone did random screen freeze and couple of reboots in nougat, but on Oreo that is not happening to me.
But i do definetly have the cell drain still after the last update. I kind of woke up by the fact that i have lost about 1h screen on time. Yes i am a heavy user so thats the first que for something is eating the battery.
What kind of cycle your battery lasts average and how is your SOT on nougat? My is average 27hours on time hours and sot 5-6 hours

I am unable to advise you on SOT as i don't monitor this, i am running a custom rom with nougat base (Sac23 S8 port) i have a battery life of between 29 and 32 hours, never really goes past 40% remaining at the end of the day.
After the Oreo update, my s7 active has really sucked. A lot. It overheats, battery drain is through the roof, it lags constantly, the camera takes a solid 20 seconds to respond at times, and it just generally sucks. The problems sometimes seem to be heat related, as it slows down even more when on charge. I'd seen on another forum that flashing the older CP file would fix the heat issue. Anyone have any luck with this? I haven't done much android modding since the days of ICS/JB/KK, before knox and all of that. Would doing this brick me or trip knox? Any alternate suggestions besides ditching the awful carrier AT&T is in favor of a lesser evil that allows me to use a third party phone with WiFi calling or VoLTE support? That's all that's keeping me with ATT branded phones now, as where I live has little 3g reception for an urban area, so having to drop down on calls without VoLTE is a no-go for me.
Thanks guys!
Have you tried doing a hard reset on the phone first? It sounds like you updated to Oreo with all of your junk on it. No wonder it caused so many problems!
There isn't a way to downgrade from Oreo.
No way to downgrade from nougat but as I understand it, isn't it just the boot loader that can't be rolled back?
I'm not sure if what you're proposing is actually compatible but you could always check.
Best way to keep all your bits and pieces in my opinion is Samsung backup.
Just did it myself and I am getting better battery and cell signal than I ever have! On a two+ year old phone!!
I just got 4 God damn days of light use between charges!

Sorry, been away for a few days. I have done a reset and it works alright for a day or two then back to total suckage. I managed to drop 55% battery in a matter of two hours this afternoon with moderate use. Bright side, it was cold outside, so I got a nice hand warmer. What did you try? Flashing the older CP/CSC?
I was under the impression that the older OS wouldn't work with newer bootloader.

Yeah, I've done two hard resets so far. No luck, but I'm backing it up again for one more shot.

Before doing anything drastic like attempting to flash CSC from a previous version, have you tried clean flashing the following rom in latest modified Odin including all relevant wipes?
G891AUCS4CRJ1_CL13639069_QB20030093_REV02_user_low_ship_MULTI_CERT_meta
My original comments were more towards the fact that radio behaviour on this rom has been totally different for me than every other version I've had on the device, as a result I seem to be getting much better battery life. I'm not sure what CSC it comes with, but it is certainly acting in a different fashion to all previous versions: Lots more time with 4G icon, less with LTE. Far more readily jumping over to 3G when the signal is stronger etc.
After charging my device is still getting hot, but not during general use. I think my battery is just dying a slow death - it only has 3000mah capacity now. A real shame that it isn't replaceable without defeating the waterproofing.
If the Sonim XP8 were a little bit better specced I would buy one in a heartbeat.
Nice, I'll give that one a shot. I was going to flash a clean install of CRJ1 tomorrow after it downloaded. Don't have very fast internet here. I appreciate the input!!!
If it weren't for AT&T restricting VoLTE to their branded phones, I'd jump ship to oneplus or anything in the pixel lineup. Or the LG g7. Or literally any third party phone that wouldn't force botched updates and bloatware down my throat constantly and re-enable crap I've disabled with every update. But where I work has great LTE signal, very very little 3g/HSPA+, so not having VoLTE isn't an option. Same for wifi calling where my parents live, poor signal so no use having the phone when I visit if I can't use wifi for calls/texts.
Currently using my old g5. Whew. I forgot that this thing would fry eggs with light use. But at least the battery is replaceable. Tried replacing my aging S7 active battery on my first one. Four days later the bottom half of the screen died. Oops.
I loved my Moto X Pure. Got it unlocked from Motorola and used it on AT&T for years. Then came the OTA to Nougat. At first, was excited to get the update like everyone else. Then weird issues started. Battery not lasting as long. Phone would hang a lot. Phone would freeze then soft reboot. Ring and SMS tones would sound like they were being bogged down. LOTS of problems. I have wiped the phone and cache completely many times from Recovery mode. Check to see if it was any apps doing the issues. Was doing this ever since 7.0 was OTA on my Moto X Pure. When I had 6.0.1, it was great. Sure, battery charge was still lower than other phones but it never missed a beat. Would LOVE to bring it back to 6.0.1 and use it until it is really not usable anymore as I am not able to buy a new phone (disabled, hard to get a job, living on SSI).
I have read some threads and many were stating you cannot go back and if you did to 6.0, you have to go right back to 7.0. Is this true? If so, guess my smartphone life is at its end. lol
UPDATE: After much research, found out I can go back to MM but don't do the OTA and all will be good. I am guessing from the forums that everyone has moved on from this phone. Which sucks as the phone itself is still good just the official 7.0 update is terrible, as per original post. And not seeing anymore dev work on custom root ROMs either. Would love to have the money to just buy a new phone but 2 things bother me doing that (actually 3, the 3rd is I am poor ). One, the phone is still physically great. Has plenty of RAM and power to run all apps today. And two, I hate the throwaway society that is now. Wasting rare resources and making so much trash all over with tech that is still usable. And why phones are so damn expensive now.
Anyways, guess I can do the MM 6.0.1 downgrade and somehow make the notification to OTA update go away or use N 7.0 and have to factory reset the phone every 1 to 2 months.
nothing is wrong with 7.0, i bought my pure refurbished off eBay and battery sot was just over an hour and i thought it was 7.0. i downgraded to 6.0 and nothing changed, so i went back to 7.0 and there you have it the phone bricked via the ota. i followed the sd card boot to repair the boot loader and the flash stock 7.0 again, lesson learned. long story short i got a new battery off ifixit with the tool kit and i'm getting 5 1/2 sot with no lag. for more battery time, nfc off, location services set to WiFi battery saving with GPS off and radio set to 3G not LTE. it's the 2k screen resolution that is the battery killer imo, just my 2 cents.
Sometimes it just a bad update, and reflashing the same full firmware will fix issues.
