[G930FD] Seeking help for battery drain in Oreo. Many thanks - Samsung Galaxy S7 Questions and Answers

Phone: G930FD
ROM: G930FOZS5ESG5
Maybe this question is asked by many guys here. I follow their instructions to reboot, re-flash via odin and factory reset for the phone. Nothing improvement.
I see the update for the ROM for ESL9 in Jan 2020. However, root is must for my daily use so I worry for the lost of my root after upgrade and the process is irreversible since the BL will be upgraded.
The android system battery drain is 30% for 8 hours during my sleep. The phone is also hotter in normal use (chat and web browsing only, no Youtube or video watching) when compare the ROM in android 7.
Any helps? I still dont want to buy a new phone as Samsung really want us to buy !
It never happens in android 7.
Great thanks.

[Q] ICS 'After-Upgrade' advice please

Hi.
Sorry if this topic has been thrashed to death.....
I'm used to working with PC's flashing BIOS etc so have some background knowledge, but am new to Andriod.
Relevent Info....
Phone: Galaxy Note GT-N7000 (Not Rooted)
Firmware: PDA:LQ2 / PHONE:LPT / CSC:LP4 (XEU)
Baseband version: N7000XXLPT
Kernel version: 3.0.15-N7000XXLQ2-CL605927 [email protected] #3 SMP PREEMPT Tue May 22 11:17:48 KST 2012
Build number: IML74K.XXLQ2
I have upgraded from GB to ICS 4.0.3 through Kies using the official samsung release.
ICS seems to have given me no noticeable advantages and some disadvantages, but I hate to give up on what should be an upgrade.
Since the upgrade I have been experiencing lag regarding screen touch / watching video online / Battery drains faster, in fact many of the issues others are reporting. Some issues I have managed to sort after finding difficulties with other apps (JD was causing Wifi probs re. AOSP(?) ). I have also removed the battery for some 5 minutes and cleared the cache from all apps that I can.
I have done much reading and am unsure regarding one point, and so to the crux of the thread and question:
Some have reported performing a factory reset helps cure these problems, but I have also read reports of factory reset bricking the phone. The warnings given NOT to factory reset refer to 'ICS leak ROM'.
Is the official ROM released thru Kies by Samsung the same ROM as the leak version and will performing a factory reset with the ROM I have used likely brick the phone?
Sorry to take up your time and thank you in advance for any helpful information you may give.
Update:
After speaking to T-Mobile support I was assured that should the phone become unusable after a factory reset then they would replace the phone as I had done nothing improper, and they advised me to go ahead and do it.
I have now reset the phone and wiped the cache and the phone is still usable.
First thing I tried was to test the lagging movies through internet (demand 5 in my case). Was asked to install adobe flash which I did through google play (v11.1). End result movies still choppy. I have since learned of others having problems with Adobe flash in browsers so this problem may lay at their door.
Screen touch lag seems to be gone now. Too early to tell about battery drain.
Regards to all and good luck in your upgrading.

HTC One E8 bugs

Up until about a week ago, my HTC One E8 dual sim (M8SW - China Unicom) had been working perfectly, albeit only running android 4.4.2 as unknown to me when i bought it, it had been rooted and TWRP/Super SU installed (I assume because I'm in Australia and it's a chinese phone... ebay purchase...)
I'm not entirely sure why, but the battery life is now draining literally about twice as fast, and the google play services app seems to be using up a fair amount of the battery. I've tried a few apps (google services fix etc) to try to amend the problem, and have completely reset the phone, but haven't had any luck.
Just wanted some thoughts as to whether upgrading the phone to Android MM would fix this?
I've attempted to do so, but because my phone is rooted I can't get OTA updates. the other issue I have is that I can't get a copy of the stock recovery (the link provided at http://forum.xda-developers.com/one-e8/help/htc-one-e8-mid-cid-ruu-ota-twrp-t2903210 does not work...) and I believe I need to install the stock recovery to get the OTA updates. I'm not confident enough to try and install a custom rom and I have no issue with HTC 'bloatware'...
very much a rookie, but would appreciate if anyone is able to help as the phone is great and I'd rather not fork out the money for a new one just yet...
thanks
Hi there! I also bought a M8SW and also from eBay with the ROM in bootloop mode where the previous owner attempted to put in another ROM but failed but that's another story.
Not sure what's wrong with your phone battery drain but I initially finally got stock LP on mine and the battery life was good.
When I saw the MM update, I jumped on it straightaway but struggled to get OTA working as my initial LP was rooted with xposed hence my little journey to get back to stock LP and then OTA to MM here: http://forum.xda-developers.com/one-e8/general/tedious-update-m8sw-to-marshmallow-twrp-t3346318
I would say that MM seems to maybe drain the battery faster than LP but tbh, I love the super smooth stock Sense. Only thing to watchout for is that xposed on MM is not fully working for all the modules. That was nearly too much for me but I have stayed with MM with xposed with N-ify, Amplify, XNotifications and SenseToolBox - all semi working for the bits that I need.
My battery lasts for at least 2 days before I need to charge it. My typical usage is low: WhatsApp, twitter, FireFox and occasionally Music, News Republic and VLC to watch videos.
The E8 still cuts it I think. I don't play any games on it and recently I am using so called Sense8 HTC10 ROM which is pretty good - definitely recommend it: http://forum.xda-developers.com/one-e8/development/s-team-e8-s4-20-2x-ported-htc-10-sense-t3364650
I'm pretty keen to get a stock version of MM on the phone - provided I can get this issue sorted the phone will last me another year or two at least.
By the sound of things, if I want to get the stock version of MM or LP on my phone, I'll need to convert it to the European model?? is that an easy thing to do? I assume it's just installing a different ROM??
Alternatively, if I download the ROM you provided the link to, I should be able to install this onto my phone and have MM with this different version of sense?
thanks for your help!

[Completed] My Note 5 Extreme Battery Drain on Marshmallow and Can't Downgrade to Lollipop

I been having an awful battery life....my android OS is usually 30-50 when idle and android OS 100% when fully charged.
I didn't do anything with the phone for 3 hours and yet it drained 30% battery. I try downgrade back to lollipop but it turns out that the new software update restricted me from downgrading the software. The reasons are unknown to me. Having VoLTE on doesn't do much battery drain on my other xiome phone.
I disabled most bloatware using PRO DISABLER TOOL and disable location and location history. My display is set to 50% all day without turning on the auto brightness but still battery lost when idle.
When i try to downgrade to lollipop, odin failed and the error was hidden.img. I search for solution on the web. Using method of extracting and deleting the hidden.img before i flash again but still failed. I'm in a loop right now dealing with this software issue.
I'm using a Malaysia Carrier XME built. Galaxy Note 5 Duos (SM-N9208)
I really need help in :
1) can I downgrade back to lollipop and if can, HOW ?
2) if i can't downgrade back, can you guys help me in dealing my battery problem.
Thank for helping me and other people who has the same problem as me...TQ XDA

Greetings and welcome to assist. The error message from odin is because you are trying to install a firmware from a different carrier, the csc file is probably too big which means eithet use a fitmware with a pit file included or try and find a firmware for the carrier the phone was shipped with.
Too fix the battery drain I would first try wiping cache and davlik/art cache and if that didnt work factory reset. You could also install better battery stats and see what is causing the drain, why not create an account and ask here

Downgrading Firmware without Losing Data?

Ever since I upgraded my Verizon S8+ to firmware G955USQS1AQI6 two months ago, I have been noticing decreased battery life (last night my phone lost 22% with aod turned off, most of the drain coming from Android System and Android OS) and more stuttering in general, which is why I have been scared to install anymore updates on my phone. I want to downgrade to the G955USQU1AQGL firmware, which was what I had before installing the crippling update. The question is, if I flash the firmware to my phone from my computer using Odin, will I lose any data? I am asking because a factory reset is ABSOLUTELY the last thing I want to do for my phone.

Yes you will. No you can't do it without a factory reset.
Backup your stuff first

I keep finding certain threads on how to do it, but it never works.
Yea, me too, this damn J7 is so bad I'm seriously thinking of ceiling US Cell and having my J3 turned back on it was faster, better and the battery lasted longer at idle, the J7 almost got thrown against a block wall yesterday at work
After extensive search I've found a soloution.
T-Mobile put some heavy security on this phone, so it's a bit different then potrayed.
You'll need to flash it through Odin using AP of course, but in the Odin settings turn off auto reboot.
Once the flashing is finished pull your battery, and leave it off for 3 seconds before putting it back in. Hold power up and home for 3 seconds before additionally holding the power button. You should be in TWRP mode. From here go to settings and reboot back into system mode, not bootloader.
TWRP will now be on your device, despite OTA.
Now, this device doesn't have much support from the Android community in general, so always make nandroid backups, and I would really recommend a systemless root like Magisk.
Everything works just fine for me, things like Xposed work just fine too.
