[Q] Some General G3 Questions

Hey guys ! Today I traded my S5 for a G3 and I have some questions :
1. Which is the latest and which is the best firmware ? I am currently on V10H. I see that there are V10i and V10j firmwares, but I don't get a OTA. Should I manually flash them and are they newer and better ?
2.Is it normal for the phone to heat up so much. My G3 heats up just from listening to music and using facebook messenger on 3G. The first boot after updateing my phone it was hot like an oven. Barely touchable on the top side of the screen. (also the brightness could't go beyond 90%)
3. If I root my G3, do I loose my warranty ?
4. Can I do something after rooting to improve the battery life and lower down the heat ?
5. My G3 uses around 10-12% overnight (6-7 hours) Isn't that too much ? My S5 used around 2-3% overnight...
6. Also on Antutu v5 at exactly 27% I get High temperature warning and my phone reboots. Anyone else having this problem ?

Please guys !

1) I think I and J are kind of the same but others will know better, they are the latest firmware.
2) No but what you call heat and what others call heat might be different but it shouldn't get anything more than warm at most.
3) Yes but you can revert back easily to keep warranty. I used Stump Root.
4) Yes lots of things but I haven't tried any as I have very good battery. There are things you can do without rooting as well.
5) Yes that is way too much. Mine uses no more than 2% over 8 hours but I have a few of the Google things turned off.
6) Never done it but from what I've read others have had the same problem.
If you have an SD card in the phone remove it and see if the heat will stop.
It is a Saturday so give it some time for others to answer.

1) My D855 is on 10H at the moment with no OTAs available at the moment. Most of the OTAs so far have just been small bug fixes and such (the change log for J is exactly the same as H). Its not worth trying to manually flash them yourself. Sometimes the update is available by the LG PC Suite before the OTA, so maybe give that a go.
2) The G3 warming up isnt uncommon. I can usually feel mine warming up around the power button in usage similar to yours. I wouldn't worry too much about the phone being hot after just booting from an update, the phone has probably been running the CPU flat out during the update and boot process to finish everything. The limited brightness is an automatic thing put in place by LG to prevent overheating. (If it was limited to 90%, then I would have thought it is not getting that hot otherwise the brightness would be limited even more)
3) Probably. I haven't rooted mine, but I believe there is a root counter/status thing in the hidden service menu that LG may look if ever your phone is sent back by which they may deny repairs or charge you for them out of warranty. (But if it is a genuine hardware defect, they may be lenient. I sent my HTC One back for repairs for the purple tint issue on the camera with the bootloader still unlocked, but they didn't say anything)
4) Not sure about that (as I haven't rooted).
5) That usage seems about the same drain I have when leaving the phone while it is on cellular data. My G3 has superb standby battery life while it is on WiFi.
6) I think that is a common occurrence with the G3, the phone is rebooting as the phone is getting too hot.

Thanks a lot for the info guys !
When my phone reboots during antutu it is not even warm. I even tried doing the benchmark in the fridge and same thing happened. It just makes no sense.

Also 1 more question - Is there some kind of a list of apps that are safe to remove/dissable ?

Charging issues on Lollipop

Sideloaded the ZVG update a few days ago, did a factory reset, and set up my phone. Everything was working great and I loved the update... until I noticed yesterday that the phone now takes much longer to charge. Previously, using a 2A charger, it would charge at roughly 1% per min, but now it seems to be more like 1% per 2-3 mins. Not sure if this is on purpose to extend battery longevity or an actual bug in the update. Either way, it's kind of annoying. Just wondering if anyone else has noticed this.

Yes I've noticed it, but I think if you were in another non stock ROM. You would have modified kernel that may have had a quicker charging installed in it.

I noticed the same thing yesterday. I have been on stock rom, with only root, since the announced that we were getting LP. Another thing that I noticed, my battery life has gone to hell in the last couple of days. As an example, I unplugged my phone this morning at 6am (100%) and by 8:15am my phone was down to 65% and I was barely using my phone during that time. A couple of co workers have the G3 with Verizon and they were telling me that their battery life had gotten bad after the update. So for about a week and a half (I updated on the 27th) everything was running normal and now charging takes longer and battery last shorter. My next step is to back up my data and reset the phone.

I just did a search on this problem. It seems that all of the LG G2s & G3s are having the same issue since the Lollipop upgrade regardless of carrier. LG needs to release a fix for all of these issues ASAP or their current users won't stay LG users for much longer. I for one was planning on getting the G4 but if they don't fix this problem soon I will be forced to change phones before it is released on Sprint.

I'm not having any of these issues.
I've had my phone unplugged for just under 15 hours and it went from 100% to 63% in that time with a SOT of 2 hours. Granted I do Greenify practically everything and only use the radios when I need them
It does seem to take longer to charge but that is not an issue for me.
Did you sideload ZVG or take the OTA to ZVG? There are some people who have said that the OTA is what is causing problems... I sideloaded ZVG BTW.

LG G4 marshmallow poor battery life and performance ?!?!

I am on MM almost three days and i noticed huge battery drains. Tried hard reset and calibrating the battery, but no luck. Im stuck on 2.5h SOT and it makes me angry. On lollipop i was getting almost 4.5-5h SOT on 3g and data always on. I noticed some lags and downgrade in performance. Shame on you LG, please fix this.. G4 is best phone and we need best software for it.

yep, same battery results for me. i went back to LL

went back to LP too till they get MM rooted

I'm not having this problem with my mm
did you do a full wipe cache ?

I meant a full factory reset after upgrading from LP ?

I have same SoT time like LP.
Can't understand what's wrong with others.
2.5hr that's insane....

Me too ... My battery sucks...i niticed that the drain is more visible in mobile data. I don't know if gsam battery make a correct read in mm but it siad that"system logd" eats battery. In WiFi is side by side with android system but on mobile data is double. A bad joke this update. I wait root appears for lg mm and get rid of this . also chrome and Google now use more battery like before. Where is doze...after night usually I lose 5-6% now 12-13%. It's always like this ... I make the same mistake upgrading to lollipop from KitKat with HTC m8 and go worst. Now the same. Goodbye updates from me. I stay with the original software. I love android but here always sucks ... In the meantime for example my battery lost 3% when I wrote that ?

Yep, I factory reset and reinstalled everything, still poor battery

3 h SOT here too but with greenify (donation version) I reach 4 h.
By the way it's ridiculous..

By the way after I make the factory reset I run gsam monitor with no app inside... The same system logd system dbox or something are in line with the screen. So it's not a misbehaving app it's only a bad implementation of mm made by lg. They want to be the first but they become the worst.

are you using V20b or V20a ??

let me tell you something dude
If you want to get a less battery eater screen you have two solutions :
- Go back to fHD screens like Sony Xperia phones
- Go to amoled panel like note 5 with all of it famous weaknesses (SOT = 5.5 - 6 max )
For me a powerbank is the best solution to enjoy this beautiful screen of G4

Hy dude... I was talking about some background process that apear after mm update. even with this doze mode my phone running out of juice faster in stand by. I don't get your opinion ... You think that with lollipop I have a different screen? Before the update I get easily 4 h sot with some coc playing.

I guess we must wait for MM to get some software updates and optimization .. For now the best is to roll back to LP like i did and wait

you guys are doing something very wrong, my H815 battery life is insane, with heavy use, I cannot run down the battery in a 16 hour day! - I go to bed and the phone is still on over 40% - running stock newest marshmallow 20B with a few tweaks

How you do this ? My battery lasts only 2h screen on time

And how do you get v20B ? I am on v20A and it shows me that i dont have update

Horrible Battery Life on Nougat

So Just to announce where I am coming from, I am a Sony fan for the past 4 years, Had the Z2 and was totally blown away by the battery life it offered. Then I got the Z5P and even though the battery performance was nowhere near the Z2 I still got through an entire day with it without issues so I was happy.
Then came the Nougat update and all hell broke loose. I am literally getting just 6 hrs of battery life since the update. And even when it is idle it still drains battery like atleast 2 percent every hour.
Also the charging is very slow. I have a quick charger that used to take the battery life from 0 to 20 in atleast 10 - 15 mins. But now it actually drains the battery if I am using the phone while charging. And yes I have switched off the battery optimization option.
Any help will be appreciated even if it is just a confirmation that I am not the only one having this issue, which will at least let me know that it is not just my phone.

There must be some process with corrupted data after de update which is constantly executing something. I recommend you to do a full wipe, factory reset

Oh did not know this could happen. Will definitely try doing a full wipe and see how things go! Thanks a lot!

I never fully trust OTA updates, because it keeps all the applications data and some special case of your current configuration maybe is not "converted" to the new version and causes the programs to behave weird. Have you looked at the battery usage? Maybe you find the process which a huge % of battery eaten, and just wiping that app data is enough

Thanks for the reply! Yeah I looked at the battery usage stats and no specific app is draining more than 2 percent of the battery over a charge. The only things that have taken most out of the battery are 1. The Screen On Time which is to expected and 2. The Idle Phone which takes around 15% consistently in every charge.

after updating to .372 , i learned from internet that this build has battery draining issues. ( i never faced any )
after updating to .376. , the phone is as steady stable as my other xperias (btw z5p is my 6th xperia )
now there is however a catch.
1. if you updated on OTA , this means the update of 1.2gb via ota only replaced certain files from .305 to make it .372 build (android 6 to 7) --- such OTA updates USUALLY ends up having problems (in general) with battery draining issues. Such problems i personally faced during updating from honeycomb to ics. - in short whenever update is available; always install FRESH
2. if your bootloader is locked then use xperia companion to install fresh after wiping all data. (makebackups)
3. if your phone is not rooted then try disabling all un necessary apps under Apps section.
----
Trivia
You cannot compare Z5p with predecessors like Z3/Z2/Z1 and Z since
1. they were always smaller in screen size / resolution and were not 4k
2. They stops at Android 5 / 6 as their last builds and battery life was awesome w.r.t consumption

however some of friends on XDA agrees that .305 (android 6.0.1) (came out dec2016) is the BEST build ever for z5p. addressed all battery issues and it was the final build for z5p on android 6.0.1
even i am thinking to degrade my phone due to ram consumption of N is very high!
this is why xzp has 4gb ram!

I need to know. If I updated my phone to .376 and it's having this lack of battery life, DO I HAVE TO SELL IT OR DISPOSE OF IT BECAUSE IT'S LITERALLY A LOST CAUSE NOW? (P.S. I immediately did a factory reset after the Nougat install completed.)
Because apparently if you updated to this build, then returned to the last Marshmallow build, THE PROBLEM IS NOT FIXED, and reloading nougat will only make things worse. And if you updated to .378, it not only does this not get fixed, it breaks your headphone jack to boot.
Please help. I am freaking out about this battery life. I lost 60 PERCENT IN 6 HOURS OF BASICALLY PODCASTS. ?

Well, after all my trials I flashed MM back and everything is back to normal. The issue is with 7 so not sure what happened to your handset
EDIT: Re-upgraded once again= battery 8 hour life. Go into About Phone, Status and disable battery optimization. The handset reboots and incredibly this morning it was like the old days .

Maybe I'll try that. The best I was able to do was 21 hours with one bar LTE, 6 hour's sleep, and 3h40m screen on time with several hour's worth of Pocket Casts.

i confirm that on build .33 i lost my battery even on stamina mode one percent every 10 minuets over using wifi , it just keeps the battery when device is screen off -_- its horrible i didnt have this kind of problem with .253 and im wondering revert back to MM

Going from Oreo to Marshmallow & Battery??????

hello there, been following this forum for ages, and a owner of a htc 10 for two weeks....
But I have a big problem....... the battery.....It really is abysmal......
I am currently on LeeDroid oreo, but have tried other roms, and come to the conclusion, the battery sucks!
I know there are kernal tweaks, but with this phone, i just like running the basic custom rom, no bells and whistles......
i am s-off and know how to downgrade/sort signal out/CID/ADB and everything, but I am reluctant to go too far back (Although I do like marshmallow)
I know on other phones, that going back to a previous firmware...sometimes improves the battery
but will it improve my battery????????

I went from Oreo to Nougat. Battery much improved. I was running pure stock rooted. No other mods on Nougat. Took a day to settle, but I could finally leave the house not worrying if I needed to carry a USB cable with me for a charge.

And overnight, do you notice any abnormal discharge? As much as 25/30%? or less?
I have this much of a discharge on nougat and on oreo... Did not noticed much of a difference on both FW tbh... As i bought this phone 2nd hand about a month ago, it was already on N and never tested it on MM to tell if there is any difference.
Our luck is the fast charge capability this phone has...

I would say so, yes I had problems. I bought this phone 2nd hand as well. A mint Red one. Pristine condition - at least in appearance. I also have/coming from a daily driver LG V20. Which also uses same 820 chipset. So I had some kind of expectation as to what battery life around. I was kind of shocked how bad the battery was on the 10. Phone was dropping like maybe 20% overnight. In the daytime on stock before I rooted I was getting maybe 1.5 - 2 SOT hours depending on use(i'm not a heavy gamer). I had never experienced such bad battery life before on an HTC phone. I unlocked it/rooted it and started playing with mods. The most success I had was with the Helix engine. I also had some Magisk modules installed to help deep sleep. Probably improved to getting 3 - 3.5 hours SOT. There is a thread dedicated to getting better battery life on Oreo in the guides section and I'd follow that thread and try various things. Also I had done the HTC calibration a few times, and the HTC battery test just to get a sense of the battery's health. In their test, I scored an 85, so I'd say the battery was OK. Not in the area of being a replacement.
But in the end, I was curious to go back to Nougat and then maybe on to Marshmallow to see how battery life would be. Simply going down to Nougat, I was satisfied. Not quite as good as my LG V20, but close enough. Don't feel the need to go down to marshmallow for it.
Maybe in the future I'll go back to Oreo on the 10, but for the most part, Nougat is fine.
From what I've read as well, HTC sort of 'unleashed' the power of the 820 chipset in Nougat, therefore when people went from Marshmallow to Nougat they reported worst battery life but improved performance especially in gaming.

Im aware on the unleashed power htc did on N, but it just don't justify the amount of energy drained. It does not make sense to remove social or other apps from background just because you need to retain battery. Still have a one M7 and the battery still is way better than this htc, with all the apps and settings i need on both, almost a clone of my m7. Im no gamer at all, and don't use whatsup, viber, FB, g+ etc.
You are saying that just by returning from Oero to Nougat, your htc 10 battery got less discharge, like it got fixed? without any mod's?
Thanks for your time to answer me!

Yeah, for me moving back to Nougat fixed my drain problems. Keep in mind, I didn't own the phone before Oreo, so I can't say what it was like pre oreo. But I finally felt comfortable with the performance/battery life I was getting on Nougat. I can't say this will work for you, but others have reported the same. Moving back to Nougat improved battery life.
Before you do it, I'd advise to rule out a hardware problem though to save the aggrivation of downgrading. Do the HTC battery test. If you fall below 70% in the test after an hour, I'd say it might be more hardware related than software.

Good morning.
Wile i was chating with you (yesterday), finally used the htc battery test and to my surprise it went from 99% to 88% in that hour test (99 because it was off and spent that ~1% booting). So, hopefully, will experience the same as the most of you who made the downgrade.
Perhaps its some part on the process of downgrading that fixes something, maybe the format of the [persist] partition one have to wipe to recover access to the baseband (thus the imei) repairs something, a kind of file system error that makes the android system use a lot of power(?).
As i told before, if do mobile repair and to this day, after several hundred of phone fix (hard and software, various brands as lg, samsung, htc,, iDeveices and china phones, never seen this type of problem unless it was hardware problems like pmic (power management IC) due to use of bad chargers / bad cables, water damage, drop damage, etc. Got this 10 and as soon i got here (xda) immediately noticed the amount of people that had the very same problem. And we are (here on xda) just a few to the many thousands of 10 owners around the globe that don't use xda or any other forums to talk about this problem.
Going to do this downgrade today. Im eager to see the result and use my 10 finally (another agnostic hope :angel!!
Thanks!
