Hi, i had this problem too and I think its definitely a hardware issue. I think Lenovo just has some quality assurance issues in the production and you and i just had the luck of getting a defective unit.

I'm really happy that i still had warranty when that happened. The main board on mine was switched, so i guess its not even an wifi/bluetooth antenna issue.
[Moto Z Questions & Answers] izamd:
Latest update 7.1.1 September security patch solve the issue.

WiFi unable to connect on 2.4GHz networks issue? :confused:
[Moto Z Questions & Answers] izamd:
I can confirm that is working for my moto Z . 2.4GHz without any problem.
[Moto Z Questions & Answers] enetec:
Yes, but I'm on MM and my WiFi/BT have not been broken by an update but suddendly with no modify... :confused:
[Moto Z Questions & Answers] Achi Shukuteki:
But what channel are you on? From what I've gathered it's only retapac right now.
[Moto Z Questions & Answers] enetec:
No more having this?

Mine (just before been destroyed by assistance center trying to change battery... :rolleyes:) had begun to not be able to connect (if not sometimes...) on 5 GHz networks too... it definitely seems an hardware issue... :(
[Moto Z Questions & Answers] octa87:
i have the same problem, no wifi and bluetooth. Anybody tried flashing modem?
[Moto Z Questions & Answers] striker59:
Losing connection happens mostly when connected to 5GHz, can't find a way to force connection to 2.4GHz.

[Moto Z Questions & Answers] enetec:
After only 10 months of "honorated" work, the battery of my Moto Z has already reduced it''s capacity from about 2700 mAh to less then 2000 mAh (both measured with Accubattery) and this is clearly showed in (a lot) reduced screen on time and total charge endurance. Ok.

BUT now it is showing a weird behaviour that I don't undestand....

If it is at a battery level under 30% or similar and I reboot it, it doesn't start anymore, showing the "too low battery" logo just after shutdown, even if without rebooting it would have worked for one or two more hours... :confused:

If I connect it to a charger it shows charging from the same % it has before trying to reboot it and I'm able to boot it. After booting, if I disconnect charger it will continue to work even until 2-3% of batterywith no issues... BUT if I try to restart it... no way again. :(

Any others with this behaviour? Any idea on how to fix this? Any idea on how to make boot more "tolerant" to low % of battery?
[Moto Z Questions & Answers] erfanoabdi:
Awesome!, Exactly same here

and after a while my 30% went to 40% then 60% now it's on 100%

my phone can only be turned on for 24 secounds

i want to order new battery :|

battery mod is helping me to keep my device on.
[Moto Z Questions & Answers] enetec:
Great! :(
[Moto Z Questions & Answers] Poor1ya:
Same here ?
[Moto Z Questions & Answers] Jeik:
You guys do know that it isn't hard to replace the battery, right? And not to mention that a new one costs under 30$(if you manage to find a good choice).
[Moto Z Questions & Answers] rickiolivas:
same here, right after 9 months.

Another issue I'm experiencing is whenever I reboot my moto, it drains 30% of the battery, it doesn't matter if it is fully charged.
[Moto Z Questions & Answers] Somcom3X:
Same boat as you guys... Bit disappointed but I'll be replacing the battery soon.View attachment 4288380
[Moto Z Questions & Answers] Somcom3X:

[Moto Z Questions & Answers] erfanoabdi:
one more thing i noticed today

i've been using my phone with battery mod for a while

and

now battery mod is started to die at 25%

:\\\\

i've unlocked bootloader in first day i bought this phone and flashed my kernel

now what problem could be?

my questions to everyone is reading this post :

verizon guys doesn't have this issue?

anyone here have this issue with locked OEM bootloader (never unlocked)

theories :

personally i've always used high CPU freq, not moto lite (1.8), maybe this is reason moto limited cpu freq

on stock rom ramdisk we have this lines :

on property:sys.boot_completed=1 && property:ro.boot.secure_hardware=0
start batt_health

batt_health is an executable binary which i'm not sure what is doing but it must be related to battery health and intresting part of this is "ro.boot.secure_hardware=0"

it means this batt_health won't launch on unlocked bootloaders !!!

(Alberto believes this is debugging tool but i'm not sure : https://review.lineageos.org/#/c/182562/ )

moto doesn't care about battery health of unlocked bootloader users?

i noticed my dying mostly was on wifi or high gps usage

we're using custom wifi drivers on kernels so might be a reason, maybe !? wasn't issue on old moto devices
[Moto Z Questions & Answers] brose111:
Had the same issue, just did an RMA with them. We'll see how that goes.
[Moto Z Questions & Answers] enetec:
Really? I thought this was hard to open/repair...

Do you have any video about it to link?
[Moto Z Questions & Answers] enetec:
Great! :rolleyes:

I have bootloader unlocked from day one and often used Incipio wireless battery in efficiency mode too... but never used overclock.

(It overheats easily on summer even without it...)

But less than a year to have a bad battery is really too early!! :(
[Moto Z Questions & Answers] Poor1ya:
Dear Erfan

This issue happened to me right after unlocking my moto z :(

Before that everything was fine.

Do you suggest any solution ?

[Moto Z Questions & Answers] enetec:
Thank you very much... BUT... it seems not so easy to me (glued display... very easy to break it... :eek: )
[Moto Z Questions & Answers] Jeik:
Well,I repaired unibody phones which could only be opened by taking the screen off. Imagine the joy when they use ridiculously strong glue.
[Moto Z Questions & Answers] Poor1ya:
Dear Erfan

I manage run batt_health with this command

# touch /data/power_supply_logger/enable_logging

# echo 1 > /data/power_supply_logger/enable_logging

# batt_health

But I cannot add it to init.d so that it runs whenever the phone reboot.

It seems that the battery health is ok and reporting to battery monitor accurately.

if you can find a way to add batt_health to startup, it would be perfect.

Regards
[Moto Z Questions & Answers] erfanoabdi:
yeah sure, flash this
[Moto Z Questions & Answers] Poor1ya:
Thanks Erfan,

I will try it tomorrow.

[Moto Z Questions & Answers] heronian:
I've had my phone repaired by the Norfolk repair centre in the UK for battery issues. It came back and i charged it to 100% then restarted it and it held only 68% charge. The only non-Google app i've added is Accubattery, which is suggesting it has less than 1000mah battery capacity. It's back on charge to see what happens next.
[Moto Z Questions & Answers] enetec:
I think you need to reset battery stats with one of the available apps (it requires root anyway...)

Do you know if thy used an original part from Motorola?
[Moto Z Questions & Answers] Somcom3X:
I'm definitely replacing this battery soon.
[Moto Z Questions & Answers] Poor1ya:
Dear Erfan

I try it , and batt_health now run in process .

but nothing changed :(

do you think replace battery resolve the problem ?
[Moto Z Questions & Answers] erfanoabdi:
Yeah it changes nothing on damaged batteries

Yeah we need to replace battery :(
[Moto Z Questions & Answers] heronian:
I've not rooted the phone, and am not convinced they've even touched the battery. Accubattery thinks it's at 1200Mah capacity :(
[Moto Z Questions & Answers] heronian:
i've escalated back to Motorola, and told them the phone is clearly not fit for purpose and i expect a full refund. I asked if they fitted a battery and if so whether it was a motorola part code. They've gone away to check. I'll report back.

Full battery Screen On estimate from Accubattery is 2h 33min after "repair". The app is estimating capacity at 1244mah, so nowhere near 2600. I've bought a lemon!
[Moto Z Questions & Answers] izamd:
I have done OTA September security update . The file size is 1188.8MB

NPL26.118-20-5 Android version 7.1.1

Mine is moto z dual sim variant.

Seems the Bluetooth issue, battery bug issue and LTE band issue is gone.

The phone now is live and kicking.

Thanks Motorola.

---------- Post added at 10:51 AM ---------- Previous post was at 10:47 AM ----------

The lesson i learned is during OTA and installing update process, always connect your wall charger and 100% batt. Don't ever ever disconnect the charger. May be thats help to reset the batt stat.
[Moto Z Questions & Answers] Somcom3X:
What's the lte band issue? I guess we need to update the blobs.
[Moto Z Questions & Answers] izamd:
Certain LTE band keep disconnect. Band 4.
[Moto Z Questions & Answers] Benoe:
What region phone do you have?

I also got this update for my XT1650-03 reteu single sim, but it is only 100MB, not 1188.8
[Moto Z Questions & Answers] izamd:
Software channel retapac . I will upload pic for reference.
[Moto Z Questions & Answers] Benoe:
When I put the same version, but retapac as a channel into Ota Link Generator Tool, I still get the same 100MB file. What was your Blur Version before the update?
[Moto Z Questions & Answers] izamd:
This is my Blur version in 7.0 , i didn't record the last version before 1 September update.

Blur_Version.25.41.29.griffin.retail.en.
[Moto Z Questions & Answers] izamd:
This i get.
[Moto Z Questions & Answers] Benoe:
You just received 7.1.1., previously you were on 7.0.0., right?

Now I think we are on the same version, we just get here with different steps. Our big size OTA (to NPL26.118-20, Blur_Version.26.51.19.griffin.retail.en.US, 1189MB) was when we upgraded to 7.1.1, but it was two upgrades earlier.
[Moto Z Questions & Answers] izamd:
Good for everybody,Bravo for motorola. They keep the promise to all moto Z owner and never let down.
[Moto Z Questions & Answers] heronian:
Motorola claim they reset my software and a battery wasn't required. Still only lasts a couple of hours and displays strange behaviour. Just charged it to 100% and switched it on and it showed 73%. Definitely something strange going on.
[Moto Z Questions & Answers] enetec:
Low quality batteries, bad SW management and killing (battery) mods in my opinion... :(
[Moto Z Questions & Answers] matrixex:
exactly they are using cheap batteries. I have already used sony phones with 1770Mah battery and it was doing better than my moto z , :P

My battery is draining at 5-6 %/hour because of it's bad SW management. Phone is heating too much and I'm still missing that headphone jack.

EDIT : instead of making slimmest phone, they should have considered improving/inserting a huge battery.
[Moto Z Questions & Answers] Vcek:
I read somewhere here on the forums the instructions for resetting battery stats for Moto Z :

Hold power button until screen turns off

Enter bootloader by holding vol down

Turn off phone and keep it in the charger for 1-2 hours AFTER it reach 100%

Can anyone with a horrible battery life try this and tell us if there's any difference, because I couldn't tell if I was getting better battery

My phone usually lasts a whole work day usually with 2-3 SOT
[Moto Z Questions & Answers] BengkelGawai:
Damn, I just read up this thread after my return period passed.

So, it might happen to any Moto Z, not only with unlocked bootloader?

Maybe any idea if using turbopack mod continuously in efficiency mode will really preserve battery or make it worse?
[Moto Z Questions & Answers] anqorallo:
I think I got a battery problem too. Whenever I'm using the phone and it reaches around 35% it suddenly shuts off. But when I restart it or plug it in, it works normally. Is this a common Moto Z problem? I'm worried that Motorola Philippines won't honor the warranty because I've got a two minor dents on the sides of my phone. They might ignore the warranty and claim that the battery problem was caused by the phone falling down.
[Moto Z Questions & Answers] brose111:
Alright, a Motorola Rep stopped by my workplace yesterday (cause I sell phones), and I talked to him about this issue and gave him the link to this thread, he said he'll include it in his weekly report. Here's hoping we can get some clearer answers.
[Moto Z Questions & Answers] heronian:
My phone has gone back into the repair centre. My turbopower moto mod has just arrived, so hopefully with a new battery (fingers crossed) and the extra power it will bring a new lease of life. I also ordered a Verizon bumper from the US,to complete the new look. The turbopower mod is a real step forward in design from the Incipio model, it both looks and feels great.
[Moto Z Questions & Answers] Achi Shukuteki:
I'm trying it now. I'll let you know. I just got my hands on an MZ. Nice phone, very buggy it looks like.

Edit: [MENTION=4234157]Vcek[/MENTION] this method worked for my phone.
[Moto Z Questions & Answers] 41LY45:
Been trying to look for sources for the GV30 battery.

Most of the looks legit ones are in US
[Moto Z Questions & Answers] smlamch:
Anybody found a solution to this yet? My phone last for an hour with heavy use but switches itself off if not charged. Greenify has been a little helpful with screen off time.
[Moto Z Questions & Answers] Benoe:
There are reports, that by reflashing the full flash image, the situation will be better. Here is an example how to do it.

But you should be careful, selecting the correct rom for your device.
[Moto Z Questions & Answers] Flowsche:
Having same errors here... 7.1.1 reteu with latest security patches of september, I just wanted to know if there are equal failures in the community and then this thread. ;)

This cannot be a battery failure for us all, I think there is a software bug somewhere... That's a typical behavior, other brands had such symptoms too and after a patch all was fine. Hope that moto will look at their "old" model too :/
[Moto Z Questions & Answers] anqorallo:
Finally sent it to the service center, last update they said that they will diagnose it first and see if it is still under warranty. The frustrating part is that it is still under a year and they mentioned that battery warranty is for 6 months only, which is bull**** because the warranty card said that embedded battery should be covered for a year!
[Moto Z Questions & Answers] smlamch:
The service center closest to me told me it will take a month for the spare battery to arrive lol Took my phone back and placed the order anyways. But 1 month is too damn long. Wish Motorola could improve on this aspect. The last Samsung Note i had, they repaired my crack display in a matter of days. I might likely go back to Samsung, even considering Mi Mix 2.
[Moto Z Questions & Answers] Achi Shukuteki:
This post I was referring to.
[Moto Z Questions & Answers] anqorallo:
Yup. If my phone will be fixed, I might as well sell it and go for the LG V30, G6 or V20. Not really a fan of Samsung, or if I'd go the Samsung route, I'll most likely put Nova Launcher on it and make it look like the Z's interface.
[Moto Z Questions & Answers] heronian:
My phone came back from the UK repair centre with a new battery this time (i believe). Accubattery was showing a capacity estimate a little over 2600mah, so that's already a major improvement! Back at the intended spec i've been using the phone with and without turbopower mod (on efficiency mode) and not had to obsess about battery life at all this last few days.

As an aside, I really like the combination of the phone and the Verizon bumper that i ordered from the US. The supplied black herringbone battery back/cover goes well with it, as does the textured plastic of the turbopower mod. With the new mod the phone feels slimmer than i thought it might. I have previously used the Otterbox commuter case and like the options i now have with the black and grey bumper.
[Moto Z Questions & Answers] heronian:
Battery life now as it should be, but both bluetooth and NFC no longer work. What do they do with these phones in the service centre?

---------- Post added at 04:20 PM ---------- Previous post was at 03:25 PM ----------

I've been told to book another warranty repair. FFS!
[Moto Z Questions & Answers] Somcom3X:
I — this made my morning.

As of writing I have 900 mAh still usable on my phone.
[Moto Z Questions & Answers] 41LY45:
According to Accubattery I have 1042 mAh left in the battery.

And it tends to auto shut off whenever it reaches 44%.

Thankfully a battery replacement with a local shop is relatively cheap.
[Moto Z Questions & Answers] heronian:
What a saga. Motorola have come back to me today to dispute that the broken bluetooth and NFC (while they were replacing the battery) are a warranty repair and they need proof of purchase again. They've had the phone three times since September and almost a week this time (in what was explained by their support team as an "expedited repair"). Expedited my arse!

Motorola and Lenovo have already cost me two months of use and multiple hours spent resetting and again testing this phone, so I've asked them to confirm that they'll honour the EU requirement to provide 24 months warranty (as they do in the rest of the EU but not the UK), and will give me two months additional warranty once they've repaired and returned the phone. If they don't agree I will know what a bunch of no-hopers they really are and buy elsewhere in future.

I remember some years ago posting an HTC One X for repair one Monday and receiving it back and working on the Wednesday. That was not an expedited repair.

As and when i get this sorted out I will let you know :)
[Moto Z Questions & Answers] heronian:
I've been without the phone since 6th November, as they clearly don't have parts to repair the bluetooth/NFC fault caused when they swapped the battery. Last week they called me to say they'd try to replace the phone. As i haven't heard anything further I've asked them today to replace the phone with a Z2 Force.

---------- Post added at 05:52 PM ---------- Previous post was at 04:56 PM ----------

I've been offered a new Z2 Play. What would you do? It's a mid range phone to replace an 8 month old former flagship model. My mods will work and i'll get a headphone jack again, but it's a worse screen and processor and my case and screen protectors will be heading for ebay. Decision day is tomorrow.
[Moto Z Questions & Answers] kooocko:
I would go for a refund at the original price if that's an option. If not, Z2Play is not a bad phone at all :)
[Moto Z Questions & Answers] 41LY45:
Battery replacement was a success. But the repair place killed my screen. (had it replaced for half price because of that)

Y'all might wanna do the iFixIt iOpener/Heat gun + guitar picks on the screen thing first.
[Moto Z Questions & Answers] Somcom3X:
My phone no longer holds a charge. Tried replacing it via geeksquad and they no longer have Moto Z's for replacement.

Currently looking for a new phone.
[Moto Z Questions & Answers] iZak17:
Exactly the same here.

I'm sick and tired of this behavior.

Just as [MENTION=6298645]erfanoabdi[/MENTION] sayd, the battery mod is the only way to keep an "admissible" use of the phone.

How did you fixed? I couldt find a replacement for battery on amazon...
[Moto Z Questions & Answers] Flowsche:
Welcome to the club! Like I said, this must be the result of a software update, totally strange behavior!
[Moto Z Questions & Answers] enetec:
Even more weird, if you try to turn on it in bootloader mode... it turns on. But if you select start system... :(

I've not fixed mine. It's dead. :crying:

I've bringed it to a repair center and they broke screen since of a bit thicker replace battery (I think...). :rolleyes:

In Italy stock batteries are hard to find so they tried with an aftermarket that it's very common on eBay... but beware, because it is a bit thicker and is very hard to close phone after fitting it... :rolleyes:
[Moto Z Questions & Answers] erfanoabdi:
I bought a battery from AliExpress

Yesterday it's arrived and i replaced it

It's good for me

At least phone is usable, Not dying in 30% but drains fast :(
[Moto Z Questions & Answers] iZak17:
Yes, I know, it is very weird to see how come the phone turns on on bootloader, but if you try to boot, it say is drained.

If it is difficult to find stock battery in Italy, now imagine how hard is to do that in Colombia :(

I saw the video where it shows how to change the battery... There's no way to do that here.

The worst part is that my phone is out of guarantee with motorola (after just 10 months) because bootloader is unlocked.

---------- Post added at 04:55 PM ---------- Previous post was at 04:36 PM ----------

I'm glad you could change the battery. I found some oem batteries on internet, but now that I know how risky is to change it, I have my doubts :s

It's a shame even if with a new battery, you don't get a good behavior.
[Moto Z Questions & Answers] Mehdi_Hp:
I have the same problem and I thought it's from corrupted ROM or something. well, ****.
[Moto Z Questions & Answers] enetec:
They reports same fast drain on mine before crashing screen... it could be related to low quality replacement battery or since of calibrating issues... but I can't tell for sure since I never had the possibility to check it first hand...

If I'll find a screen replacement at a good price I woild try to repair it myself eventually... :rolleyes:
[Moto Z Questions & Answers] Mehdi_Hp:
Are you guys sure it's not anyhow ROM related? I mean suddenly bunch of moto Z users are experiencing battery drain and shut down at 30ish%? at the same time?
[Moto Z Questions & Answers] ricardofjayme:
There is a similar post in Lenovo Oficial Forum (maybe some of you looked there too..): https://forums.lenovo.com/t5/forums/v3_1/forumtopicpage/board-id/Moto_Z/thread-id/2713/page/1

No "we" don't!! I and others posted it here and you and others always write something about changing batteries. That's simply not true, I never had problems and now since the 7.1.x update it crashes randomly at 30/40%. They did something wrong, that's a fact.
