© «Get best battery life & screen touch fix - EUROPEAN 815 only»

For information...
I installed the latest c firmware (d in build prop) with LG flash tool (NOT UPGRADE), a CLEAN install.
wiped(factory reset) before flashing, then in flash tool cleared and made a CLEAN install and factory reset after to be safe (3 resets) .
Now I get very few screen misses, and screen on time 4.5 hours.
Before this I got screen on time maximum 2,5 hours.
Just wanted to let you guys/Girls in on this as it worked perfect for me and my wife.

Thanks for the placebo

Think I've been around enough to make an accurate judgement, add I'm an recognised developer, I made a hell of a lot of mods and ROM's all developed for two things only battery life with good speed.
You don't have to believe me, what matters is for me, add I got a much better phone.

Hi smaberg,
I was wondering if you are on the Euro 815 version of the G4? Based on your post I'm guessing you are? As a guy who knows what he/she is doing, I was wondering if you could make a flashable zip of the version d firmware? I have a mac and my understanding is you need a pc for the LG flash tool?
Figured I would ask and would greatly appreciate if you could help!!

Do you have the same set of apps installed as you did before the firmware and resets?
I saw better battery results on my second G4 vs my first, some of which I assume was because I installed a lot less apps on the second unit. Which seems reasonable to me.

What device is the OP using?

I'm on international 815 (Euro).
Still using the exact same apps(didn't use LG backup Restore as it brings back the old draining Barry problem from my old backup).
And NO I can't make an zip, as it would skip some important steps. I mean I can make it, NO problem, but then you will end up with the exact same problem add the old.

hey Smaberg, can you outline the step to flash the new version? I'm using 815, but since i'm residing in Asia, my phone is not seeing any upgrades.

Yeah i also like to get exact steps you made to flash

lol at 3 factory resets..just makes me want to skip the whole ordeal
it's 2015 and google (+manufacturers) still can't get their **** together even when using the most powerful hardware available
android 5.x has been utter failure imo.

@smaberg, 4.5 hrs screenon is nothing to be specially proud on, yesterday i had 6hrs with 12.5hrs on battery. Device is H815 and firmware is v10c howecer, i got my device on saturday and did just root it this night... we will see how it behaves now.

Me too, but I did one before flash, one with the flash tool as I chose to make a CLEAN install, and the last mostly to be sure.

I know, but compared to before, with only 2 hours, sometimes even less worth stock a and b I'm pretty ☺ happy, now I'm going to deactivate some junk and see the results, and when I'm done I'll share it.
I'm trying to get the best battery without root, then with root and some of mine scripts and files mod. And we'll see where we stand. In the end maybe an ROM pure made for battery as in the old days. If some still want this? I thought/think people mostly want bling bling and speed...

Hi,
I would definitely be interested in a battery life based ROM. I find that premium phones have more than enough power you need (if youre not a gamer) so as long as the UI is smooth battery life is more important to me.
Regards,
Ravi

Only used 4% battery and got this screen on time. With everything on.

You can turn it on manually which some people do to prolong battery life rather than just when on low battery.

Correct I have it on pretty much all the time. It doesn't effect anything I do on the phone and I get a lot better battery life as you can see combined with the use of App Ops, DisableService, and greenify

I'm not sure what's going on with my battery life but it's less than five hours... I've had since noon today and it's already been charged once and taken off around 9pm tonight and I'm already down to 55%. Any ideas? I've hardly done anything other than texting and web browsing, all on wifi. I'm also not getting detailed battery stats. See below... Also, how the hell do you take a screenshot other than using screen write? Oh and i never got an update...

Yeah that's what it's always been on other phones, but my phone will not do it.
Edit: Guess i want holding it long enough. I just switched back to Android from iOS after 3 years. On the iPhone is instant lol.

did the device reboot into a recovery to install the update? curious is someone dropped the ball and left a open bootloader on the released device OR its just the monthly security patch, prob the latter...
further investigations...it did include a new bootloader. i would hold of on installing this if you want root. you never know

Lol yeah not rooting, leaving it alone

I did not install the update. I just love that they say that ATT wants to install an update and give no more information as to what or why. After my upgrade experience I'm not real trusting and was hoping someone could report what it is. Want to compare?

Sadly, it's probably a bunch of good fixes bundled in with some unwanted bloatware and security "enhancements". Lol
BUT... that's just pure conjecture on my part, as I watch the N7 forums and live vicariously through you all. I'm still happy with my rooted Note 3, can't justify the upgrade cost, can't live without my IR blaster, and so will wait.

So, anyone know whats in the update(is it just the Android Aug security update)? Any chance it really would affect root? For me, the only reason to not root is Samsung Pay and since it doesn't support either one of my cards, not worried about that "feature".

It does contain a new Bootloader, and the update was prob forced upon you. Yesterday my device buzzed in my pocket, heard the ATT ding ding dong sound. Pulled my Note out and it was optimizing apps (about 50 of them). Seems they forced the update to my Note, even though I had clicked "install later" many times through-out the day. bastards!

I believe it's just a security update.

I did not get update. Do you have to have a att simcard in phone to see update.

The only way to keep from downloading an update is to have Wi-Fi turned off or disable the update totally with package disabler pro. The phone automatically downloads any update if you are connected to Wi-Fi and will install it even if you hit install later. The phone does the install after the third time you decline it. All of my Samsung phones have done this.

Okay i sh*t you not, I read this on lunch and said in my head there's no way it forced itself, or maybe it's an option to disable under developer settings. Got off lunch and felt my phone vibrate because it was turning back on. Pulled my phone out and saw that it was optimizing apps and I'm like like wtfffffff out really forced itself. I wasnt on Wi-Fi or anything and my phones battery was at like 30% so i honestly couldn't believe it did the update as such a low battery without asking, crazy. ?

The device is brand new. You can expect battery improvements over the next few days, no matter what you do. It takes 3-7 days of charging and use for the battery to reach maximum efficiency.

Currently downloading the update. Hope it fixes my battery issues such as stopping at 88% when charging, and dying between 15 - 30%. Marshmallow sure sucks.

Does anyone know when will Samsung stops providing security updates for the Note4?
I'm glad that they are still updating this device.

^This. I was having similar problems. Replaced the battery and all the problems went away. Note 4 batteries seem to be dying faster than usual. My Galaxy S III battery lasted longer.

My suspicion is that fast charging shortens the lifetime of the battery. I have turned it off and only use it when I really need a fast charge.

I never use fast charge, don't even have a fast charger because i bought my phone used off a relative.
Anyhow, my point being. I still have my original battery since late 2015. Charge it at night, and it last me all day normal use.
I agree fast charge is bad for battery longevity.
Edit. Also is it confirmed that this new update still roots and can still downgrade?

I never used fast charge, either, and my battery died after 18 months. I could blame it on a cheap wireless charging receiver I bought (and later replaced with an OEM Samsung charging cover), but it's also possible that Note 4 batteries just suck.
It doesn't matter to me. The new battery has been working fine.

That's a big possibility, look what happened to the Note 7 batteries.
Either way batteries are gonna go bad. All you can do is try to maintain them to last longer. Plus there's a lot of variables for each user. (Temp and humidity, letting them often drain completely, the charger). I believe all these factors affect our batteries. On top of, every battery cell is not gonna be to notch to begin with.
Also, i believe my battery might be lasting better than most because, overall, compared to most people, I'm a very light user. I don't do many battery draining things. Test some roms and browse the web.

I was just able to put TWRP 3.0.1 on this ROM after OTA update to QB3. I will attempt the SuperSU 2.82 next and post my results. At the time of this posting I have a pending QC1 update I am going to forgo at this time. I understand it to only be a security update. After installing TWRP I can no longer get OTA updates (by design I'm sure). I will post about the rooting shortly.
The TWRP recovery didn't stick. after a reboot to system, and then reboot to recovery, the recovery was stock again. I think there is a fix for this. I'm a novice, but wanted to share my experiences.
---------- Post added at 02:31 PM ---------- Previous post was at 01:33 PM ----------
I did get it to root!!! For those of you wondering m process it is as follows:
I did OTA update to QB3 call me crazy but I have done back to back updates starting with PG1 and ending with QB3 today.
I put the superSU.zip file in the root of my SD card using windows I sued version 2.82 of SuperSu ( https://forum.xda-developers.com/apps/supersu/stable-2016-09-01supersu-v2-78-release-t3452703 )
ODIN flashed using the AP option and un-checking the "Auto Reboot" check box in the "Options" tab. I was able to install TWRP 3.0.2 from .TAR file ( twrp-3.0.2-0-trltespr.img.tar )
Once the flash completed I pulled the battery, then the usb cable.
waited 5 seconds or so, installed battery booted into recovery
selected install in TWRP 3.0.2
selected the SuperSu.zip file (it chews on things for a bit, and finally completes installation) Read the screen, it mentions the possible appearance of a boot loop, but indeed it is rooting. I hung in there, it didn't take but maybe 2-3 boots, and it was back to the sprint splash screen, and it booted normally.
I then installed Titanium backup, and SuperSu popped up asking to grant root permissions, I granted them.
looked over SuperSU, it seems happy.
rebooted (just for grins)
Back to Titanium, still shows root checkbox.
I can't speak for anyone else's mileage, but for me, this was straight forward, and working for me at this time.
As a bonus, after completing this process, TWRP is also sticking, and starts when booting into recovery.

My Note worked perfectly until this recent update. About 2 days after taking the update, my Note started rebooting, lagging, freezing...basically becoming unusable.
I have 4 batteries, and no matter which battery or whether plugged in or not, this happened.
Wake lock app helped but then, yesterday, the phone wouldnt boot. Nothing but black screen. Would not charge with any battery or any combo of cables and chargers.
By playing around with it, I finally got it to boot into recovery, however, there was no recovery. No matter whether I did power up or down, I got download mode.
The firmware repair using the PIT file got me back in action through Odin. It still took half a day to get the phone stable.
Long story short, it's not always the battery. I think these updates cause issues. The web is full of similar cases. My phone has been completely stock and still this happens. Even going back to Android 5.0 didn't cure the software corruption that this latest update caused me. My phone still won't work without the wake lock app.
I was thinking S8Plus but now I'm thinking no more Samsung.

This has nothing to do with the battery. This issue with the Note 4 rebooting is common and no matter which battery you use, the issue continues. I have numerous reason why that is but they seem to do with the MM updates not playing well with the hardware on the Note 4, especially the most recent updates (last 2 or 3). No matter what people try, the issue continues. The Wake Lock app seems to help a bit but this is no long term solution and honestly I don't think Samsung or Google will invest any time in fixing this issue for a device that is over 2 years old. They want people to upgrade.

Does this include stock unmodified and fully OEM phones? My wife's Note 4 started rebooting a lot in the last few days. She has done NOTHING other than standard user stuff. Me? I always mod mine or add an extended battery, but hers straight up the consumer setup, including the original battery.
If the battery, why would a battery cause this? just getting old or is this related to mods or buying after market batteries.

A phone battery (at least these days) isn't like a D battery you put in a flashlight. It communicates with the phone. When it starts to go bad, it can cause things like premature shutdowns and boot loops.
Yes, I've been running 6.0.1 ever since I got it OTA, and have never rooted or loaded a custom ROM since then. Suddenly my phone started shutting down at 40-60%, and often went into a boot loop. The only way I could stop it was to put it on the charger. But as soon as I had it fully charged, it would start giving me problems at 40-60% again.
I bought 2 supposedly Samsung OEM batteries, one from Amazon, and one with the external charger from Sprint. They both fixed the problem, but the Amazon battery sucks. It looks identical to the Sprint, but I suspect it's a clone. It doesn't last nearly as long as the Sprint OEM battery. I bet you can get a battery that is genuine Samsung other than using Sprint, but just beware.
EDIT: Just as an aside, I didn't suspect the battery was the problem at first. The battery started to swell up, which is why I replaced it. It was a lucky thing that replacing it fixed the problems.

Thanks, got one ordered. for $15, it is worth a try!

Or is it a conspiracy! Is Samsung killing our phones, to make us buy new ones? ???

Just my 2 cents. I don't know, but here is a theory.
Everyone i see make a post about rebooting issues always mentions it after taking ota's.
Now my theory, i can only speak for myself. I've never taken an ota, always upgraded through Odin. When i got my phone it was on ob7, i think. And i upgraded it through Odin since. Thank God i haven't had any problems.
So i wonder if it has something to do with Samsung's ota process? Just a thought!

Heating and Performance Issues

Hey all!
I purchased the Sprint Galaxy S4 (SPH-L720) off of Craigslist for a screaming deal of 30 bucks in April. It was a great device and at first I didn't notice the issues. After awhile though, I began to notice that it would heat up doing very menial tasks, such as web browsing. This would cause excessive battery drain and also performance issues. I have also noticed that during undemanding gaming it would heat as well. This issue isn't seen as much on the stock Touchwiz ROM (seen most obviously in custom ROMs) but is still present. So, I've a few questions for whoever is willing to help me out a little:
1. Is this issue always present on this phone, despite condition? Or is it a result of years of use? Or neither?...
2. Would a new S4 (preferably GT-i9505) have the same issues?
3. Is this a result of some difference between Sprint's variant and the i9505?
Thanks for any responses. FYI, I only use the phone over WiFi (Sprint isn't my carrier).

No; most of the reviews for them on Amazon say that they enlarge after a few charges. My sister has an S4 with that issue, and it's literally ripped her phone apart over time, separating the screen from the body and even causing the home button to fall off. If you could provide a link to a new stock battery that'd be great.

I had 6 different batteries for my S4 and never had that problem. Best thing to do is buy an OEM Samsung battery or one from a respected 3rd party such as Anker. I swear it does wonders. Especially on a device as old as this. It's a lot cheaper than buying a new phone.

Performance, no. It's a battery. It powers the device, that's it's only purpose. Battery life, yes. For performance, I would recommend trying a different ROM. A new battery should help with overheating, but could also be being caused by a number of things like apps running in the background and many other things. I recommend using Greenify if you aren't using it already.

Is the Team Wicked X ROM banner a little hint-hint?
I've found CM13 to be the best performer for me. My main concern is overheating while doing simple things like web browsing.

On my PC I have a signature, the app doesn't allow you to use banner signatures anymore. Use whatever works best for you, but if you haven't tried it I guarantee it is the most updated TouchWiz ROM for this device by far.
