Its strange for me too since they are both fast charge. And i used ampere app, they both max 2400mAh when charging (both samsung and lg) and fill the juice up for same time. Thanks for the help man. Im going to try other fast charger if they produce that annoying green tinge. But as of now, im using the samsung charger. So far, it does not produce any green tinge.

Any way to split the phone and text volumes?! I thought on 7.1.1 you could do that
[ZTE Axon 7 Questions & Answers] brophylad:
Hi,

Phone is running stock firmware and not rooted.

Im thinking its the phone and not software related as issue seemed to being happening out of no where after the phone for the last 9 months had been superb for battery life considering usage it gets.

Originally thought it could have been an app update that caused it so uninstalled all previously installed and updated apps but same issue keeps happening with rapid battery drop off. Next course of action was to format phone and start from scratch with nothing installed and only my gmail account added. The same issue with battery rapidly dropping when not in airplane mode. Issue is shown in screen captures below with phone basically stock and no apps installed.

First 2 images show a day where I was working and had phone in and out of Airplane mode which shows the graduall drop off of power but then the drastic vertical drop was when I put phone back into service.

images 3+4 show battery life over 19hrs where phone had to be charged twice due to battery drain.

Can anyone shed some light on this? is my battery fried?

On another note should this need to be sent back under warranty it was originally bought direct from Amazon spain - would it be ZTE UK I contact and if so whats the best way to do this?

Thanks for looking....

It seems some of us has this issue. It might be software like the modem! Since it drains so fast from a weak signal. I really hope there's a fix. I hope oreo fixes this too
[ZTE Axon 7 Questions & Answers] brophylad:
Although if you look at my first screen capture even at times when the phone has strong signal there is severe drop off of power. Has there be any mention of ZTE replacing batterys under warranty?
[ZTE Axon 7 Questions & Answers] wallor77:
I was telling on XDA that b08 is worst ROM ever. More people have this issue, its software related. Not hardware of any kind. Cant recall what is the name of android battery saving function. Snooze or something. It doesn't work at all. I managed to improve battery life by uninstalling some apps that maybe drain battery. But my phone can't manage to stay alive for more then 8 hours moderate usage. Same thing goes for mic echo issue. That is not user fault. Same goes here with German b08 ROM. I personally thing that German group is more like copy paste type of developers then actual European support.

For me best ROM so far in terms of battery life was MM B06

Whats most irritating is that i am back with old type of resolving issue about this phone. Disabling 2/3 of processes. But in this case for battery sake not processor or ram issue
[ZTE Axon 7 Questions & Answers] gecko702:
this is getting crazy theres like 3 threads now of battery drains
[ZTE Axon 7 Questions & Answers] Teet1:
Don't even know what it is. I'm really guessing it is A2017U Bootstack B35. Any custom rom under any kernel yields the same horrible battery life. I'm afraid of flashing an older bootstack. Perhaps the safest one is LineageOS universal bootloader B15 and Modem
[ZTE Axon 7 Questions & Answers] Teet1:

That battery usage is NOT normal. I believe culprit is the modem. The battery seems to take a hit more when the signal changes rapidly. I had a strange anomaly yesterday when I had 69% battery for over 40 minutes. The signal was more or less much more stable than that in another area. Those screenshots were taken at work. I've never had that much drain prior to updating bootstack

Edit: this is that anomaly from yesterday https://imgur.com/a/VnDBS the signal was more or less more stable and the battery was really good. Like normal. And that was with music playing from Spotify via mobile data and Dolby atmos and viper4a while browsing Facebook and using messenger. So yes, I believe it could be the modem

I don't know where to look up my version, but I'm running on the latest resurrection remix and I'm also getting like 2 hours sot max... It'd be really nice if there was any way to know how we can circumvent this or maybe update to a newer version of the bootstack - I'm on an A2017G

I also made a thread here: https://xdaforums.com/axon-7/help/horrible-battery-life-t3712365
[ZTE Axon 7 Questions & Answers] Choose an username...:
i'm pretty sure it's not the bootstack, otherwise everyone would have the same problems - i had 7h SOT on RR.

So, miflash didn't work?
[ZTE Axon 7 Questions & Answers] vadsvads:
Sorry, what do you mean?
[ZTE Axon 7 Questions & Answers] Choose an username...:
My question to everyone with this problem was if flashing a full stock image through MiFlash wouldn't solve it. I've had this problem; also random reboots which didn't get fixed even by updating from M to N, and MiFlash (or going LOS then back to stock) fixed it. I thought i had told you to use miflash, but it must have been someone else lol

What's the point in fragmenting the issue in like 3 different threads? Are the other ones dead?
[ZTE Axon 7 Questions & Answers] vadsvads:
Yeah, sorry, either you meant someone else or I missed you giving me that advice - anymay, I might try it this weekend.

So you're running on RR now again after going through this progress and you're getting a whopping 7 hours sot? When did you buy your Axon (or rather, how old is your battery)? 7 hours sounds like Utopia to me
[ZTE Axon 7 Questions & Answers] Choose an username...:
Nope, not like that.

I bought my phone in February. I mostly used it with stock, but tried some custom ROMs although most were horrible to use back then. One day around May (i think) I had some trouble going back to stock, and I DFU-bricked my phone. So, 4th categ brick repair. After using MiFlash to install Marshmallow B10 I used it for a couple weeks (Xposed being one of the reasons), but battery life was around 3.5h SOT and I had random reboots, even without xposed... I updated to the latest N and it was exactly the same. Back to the drawing board then.

So I flashed RR, then a kernel, then added substratum + swift black to the mix, and I got 7h SOT.

Then I got bored of RR and returned to stock, and that's when I got the 3 hours of overall battery (not even SOT) so I used Nuclea for like a month. After that I went back to stock and had the usual 4-5h SOT.

You basically have to reinstall the system from the ground up and your battery life will get fixed eventually if it is a software problem. But better do it fast, because each charging cycle is bad for the battery
[ZTE Axon 7 Questions & Answers] Kantastisch:
I know that this is not topic related and everything but how is the sound in custom roms? Isbthe speaker as good as in the stock rom and what about the headphone sound? I am thiking about installing a custom rom but I want the sound to be just as good.
[ZTE Axon 7 Questions & Answers] Choose an username...:
I don't know about the speakers but I believe they sound okay (way better than my friends' S7edge/S8/3T for sure xd). As of headphones you HAVE to flash the AK4490 patch or you'll be using the other DAC.

I recommend to use Viper4ARISE or the V4A magisk module from shadysquirrel. You'll learn to live without Atmos since the AK4490 will work on everything, so it compensates with soundstage.
[ZTE Axon 7 Questions & Answers] Kantastisch:
never really used the dolby feaute or app anyway
[ZTE Axon 7 Questions & Answers] Choose an username...:
that's okay then

I'd even say that standard mp3 sound is even better on custom (with poweramp or even youtube) than stock
[ZTE Axon 7 Questions & Answers] Kantastisch:
Okay, so RR + custom kernel + substratum swift black is the best for battery life? Which kernel exactly?

And I just realized you're the guy who helped me to unbrick my axon 7 2 months ago or so lol
[ZTE Axon 7 Questions & Answers] Choose an username...:
lol

yeah, pretty much. It's a matter of trying kernels. I may have also experimented with AKT profiles too, but I don't know if I did...
[ZTE Axon 7 Questions & Answers] Kantastisch:
And is rr without a kernel still better or the same as stock when it comes to battery life? And did you try LOS?
[ZTE Axon 7 Questions & Answers] Choose an username...:
don't know, that was around 5 months ago. But stock and LOS are basically the same crappy thing, barely 4 hours SOT. I've been using BeastMode kernel on LOS though, so i think it traded battery for performance
[ZTE Axon 7 Questions & Answers] Kantastisch:
Hm, I'll try it out. What would you recommend trying first when not really caring about performance too much?
[ZTE Axon 7 Questions & Answers] Choose an username...:
dunno, ax7? Or maybe just stay in the stock kernel for some time

Just remember to flash gapps right after you flash the ROM (without rebooting) or it may crash constantly and fucc up your battery life
[ZTE Axon 7 Questions & Answers] Kantastisch:
Yeah, but which rom. I'm trying to avoid getting a custom kernel
[ZTE Axon 7 Questions & Answers] Choose an username...:
Maybe Nuclea; RR works too

[ZTE Axon 7 Questions & Answers] Teet1:
Alright so I had a strange thing happen to me yesterday and today. After reading [MENTION=7799420]Choose an username...[/MENTION] post about different SOTs on different ROMs and said RR had the best, I decided to flash RR from stock B32.

This is on an A2017U device.

I went to recovery, and wiped System, Data, Cache, and Dalvik

Attempted to flash RR, but couldn't due to TrustZone, so I said screw it, I flashed the Universal Bootloader B15 and Modem from the LOS 14.1 thread

Wiped again

Flashed RR

Wiped dalvik and rebooted without flashing gapps

After awhile of using the phone with no gapps and using facebook though browser and LTE on, the battery was amazing, with what seemed to have approximately 6-8 hours of screen on time.

https://i.imgur.com/szSkgMs.png

with 1 hour and 10 minutes of the screen being on the entire time, from around 93% to 80 in one hour and 25 minutes is amazing. I would drop 10% in less than 20 minutes with screen on the entire time.

So, I went ahead and flashed gapps, installed my apps and played a bit of animal crossing and flashed HELLSGATE EAS kernel

https://i.imgur.com/YTtE2xQ.png

battery still went normally and stably, still went the 7 hour battery life/screen on time approximation. Keep in mind i had my screen on for the full 3 hours, give or take 15 minutes.

So by the end of the day, went to bed with my battery at 29% and 5 hours of screen on time and approximately said 2 hours left. I plugged in my phone to charge and went to bed.

I wake up the next day and unplug my phone and use the bathroom. 30 seconds in, it drops from 100 to 99%, then about a minute and a half it dropped to 98 and thus began the horrible battery life cycle once again. Approximately 3 hours of battery life with the screen.

https://i.imgur.com/WiqpcA6.png

Screen on was only 42 minutes. the 19 hours from 74% is a lie, because its counting the moment I had the screen off and LTE off, which is STILL very awful battery life since that means I have 19 hours left of battery WITH THE SCREEN AND LTE OFF

Here it is after leaving work.

My phone is not being held hostage by wakelocks. It has to be software.

Here is Android OS using up a ton of battery

https://i.imgur.com/rtqO29l.png

It might be RR, I highly doubt it though. IT was fine before I charged it fully, so I'm thinking clean flashing a ROM without charging fully will give you amazing battery life and charging it fully absolutely destroys it. Who knows. I will test my theory soon. This is so confusing so if anyone has solutions I'm willing to try anything.
[ZTE Axon 7 Questions & Answers] Choose an username...:
I've been thinking: What if you install another person's backup from an okay device? There's a B05 ROM that's installable as a TWRP backup, this could actually work

I'm just giving ideas, maybe i'm wasting your time as well :p

Another idea: Charge it to 100%, then use Battery Calibration, made by NèMa (i think it's like that) then monitor the voltage as it drops (for example write down the voltage each 10% battery drop). Also Ampere might be useful; check current draw.

Yet another one: Wipe system, flash RR again plus whatever else you use, flash AX7 kernel or any with battery charge limit, limit charge to 90%, then monitor draw and all that stuff

And lastly, try MiFlash with a stock package if nothing else worked

Just go to the Device Manager, uninstall qdloader, select 'delete driver software', then get zadig ready, and hold all 3 buttons until the device manager spazzes. As soon as Windows starts to install the driver, press the button on Zadig and you should be ready to go

If anything fails just hold all 3 buttons until that thing happens and try again (i guess you're using axon7tool?)

On other somewhat unrelated news, I seem to have 5 hours SOT on A2017G B09 (latest nougat). No kernel (pretty obvious, as there isn't one xd) or even Substratum yet.

[ZTE Axon 7 Questions & Answers] Choose an username...:
Look just download the flashable zips that raystef66 made and flash them as he says. I don't know if you can go to stock just by flashing them but maybe you can

Or fire up MiFlash, download the official B09 zip, and flash it from there. You'll need to install TWRP again later, but that's it.
[ZTE Axon 7 Questions & Answers] vadsvads:
Have you tried it yet? I didn't have time to, unfortunately, but I want to try it asap - I'm just not sure if I can flash it over my current RR (or on my A2017G model at all, for that matter) ^^

[ZTE Axon 7 Questions & Answers] Kantastisch:
Well, I initally wanted to get a custom rom but I seem to get pretty okay SOT on the stock rom with everything stock official.

Mathematically what would equal around 5h SOT, so it's not too bad but not great either.

The device is 1 year old tho according to the pre owner and why would he lie.

I am using the a2017g model.

hopefully something will get fixed not to mention if we destroy our batteries itll be hard for us to find parts now that axon 7 is discontinued

im running stock SOT is fine for me 6hrs max i dont use it as much but from 100%to 99% takes almost 2hrs if idle better than last time on RR 100%to 99% in less than 10 mins idle!

"6 hours SOT is okay"? Are you sure that's your SOT? That is pretty darn good

Hey, could you use Trepn Profiler to see if there's something wrong with the CPU governors? I don't believe that's the case, but hey, why not. Simply go to Advanced mode, Settings, disable all overlays, and enable only CPU frequency data points (all 4) and battery power. Then go back, Profile System, and leave it profiling in the background. If you can put the lock on the app (so that you don't close it) do so.

After a day's usage or so, go there and take a screenshot of the 'Stats' tab

My battery was fine for a while, but then this suddenly starts to happen where it uses up to 200-600 mAh throughout the day. Rebooting fixes it after a while but then it happens again. My phone also starts to lag a bit. I don't know what causes this, but it shows up with every ROM. I don't know why this is happening now when it was fine before. If you have bad battery life, does it have Android System showing up?
[ZTE Axon 7 Questions & Answers] Kingo64:
Yes, it's Android system showing up but BBS is telling me that it is just because it owns the alarm/wakelock schedulers that apps are abusing. I suspect some common app most of us use is the culprit e.g. Google Maps or Google Play Services.

Can anybody without Gapps comment on their battery life?

I had the same problem. actually I still have the same problem. I sent the phone back, for warranty repair and it was free (they also paid for the FedEx postage, they really do have excellent c/s), it came back about 9 days later and the issue is still there. they told me originally that when they received my phone they would send out another phone that was already refurbished but I got the same phone back, it still has the sticker with the serial number on the back. i will follow-up with them & let you know what happens.

So you said you used rr with swift black and some AKT profiles and got up to 7h on screen time and I finally could unlock my bootloader after disabling the internet on the PC and downgrading to b10 6.0 I flashed nicleaRom with twrp, rooted it, substratum swift black theme and using Project X.A.N.A extreme battery I still only get about 5h SOT and tbh I expected more. And it's really odd that every google app that I opened, drained tons of battery. I uploaded 2 small files voa google drive and it got a drain of 10% with a cpu load of only 3 minutes!!!! And YouTube (blacked themed mod) used whopping 27% with about an hour of use!!

The screen itself was only about 9% after 4h 20 min and 27% left.
[ZTE Axon 7 Questions & Answers] Choose an username...:
X.A.N.A. extreme uses a very weird way to achieve good battery life, which is dividing load between the LITTLE and the big cores. So some load goes to the big cores too. Use another profile, I think Zhana works okay.

Also you may want to keep an eye at CPU average states. Just use Kernel Adiutor and, if you see high average frequencies, then the AKT profile is utter crap. The idea is to keep the frequency as low as possible at all times
[ZTE Axon 7 Questions & Answers] Kantastisch:
All look really low so that isn't the problem. But I am more concerned about this google app drain. What is this??

88% with 32 SOT. I've tried so many things and can only get about >3.5 SOT and the best I've gotten was 4 hours and 20 minutes. Really don't know if it just depends on usage, apps and signal. I have bad LTE signal most of the time so I changed it to H+ and I lose 0% from signal instead so signal is not a problem now. Maybe apps and usage, most I use it for is browsing with chrome and Facebook. Sometimes I just think my battery life is dying but I don't think so.
