Very poor battery life Moto Z with 7.1.1 - Moto Z Questions & Answers

I run stock 7.1.1 on my Moto Z and lately I have seen that the battery life is terrible. If I take the phone off the charger at say 7am I will be lucky to get to 3pm before needing charging. I don't play games or watch videos using the phone primarily for phone calls (!), texts, email, news reading (I use Google Playstand) and the occasional social media (no Facebook).
The only "customisations" I have are using the Pixel Launcher 3 instead of the Motorola one, the Google camera and the native AOSP dialer rathen than the Motorola one.
I had seen a few posts from folks saying a factory reset might fix it but I want to avoid that if I can with many work apps having quite convoluted processes to get then to authenticate and sign onto to Enterprise servers again,
Thanks

Maybe reflashing the stock ROM via fastboot avoiding the line "fastboot erase userdata" because if you'll avoid this line your personal data wouldn't be erased

Check your battery wear using Accubattery.

I have the same issue. Did you find any solution?
Sent from my Moto Z using XDA Labs

the only thing that help me with this problem, was a factory reset with a fresh install of all the apps, avoiding the restore

You could try to install Greenify https://play.google.com/store/apps/details?id=com.oasisfeng.greenify if the phone uses a lot of battery when the screen is off.

I've been running that app for a few days now and it says my battery is 91% of health which is pretty poor for a phone and was purchased new in April of last year.

It is?
Then what about mine?
87%, purchased about the same time (about a month later).

Given both our phones are less than one year old I wonder if Motorola will replace the batteries under warranty?

I first let the app run for a month... my first value was 83%, which was awfully low...
I could live with anything nearby 90%.

My phone has 1 year and battery was terrible. I've got it replaced and it's working fine now.

HOw did you about that? I went to the Lenovo support forums and a senior agent replied as follows:
https://forums.lenovo.com/t5/Moto-Z/MOTO-Z-battery-life-terrible/m-p/3927759#M4349
Only one day but after deleting the cache partition, today's usage is much better - almost 14 hours.
However battery health is only 90% which seems low.

If you follow accubattery recommendations you should keep your phone ideally between 40-70% or at most 20-80% and don't ever let it run to zero unless you're recalibrating the battery and don't charge it to 100%. My Z Force is from August 2016 is at 95%, but even with that there's been a reduction in battery life.

I went to a local repair shop and paid something about 50$ to get it replaced.

I was playing a Daydream VR game that froze up and had to hold the power button to restart. Battery was around 70%, when the phone restarted it showed around 15%. My battery has been downhill since. This was last week. Today I have my phone plugged in charging with the Incipio battery back on and both showed 100% with the phone on. Powered the phone off while still plugged in and the power off screen shows the mod as 100% but my phone battery shows 78% and will continues showing 78% after 15 minutes of charging. Powered it back on and the mod is still at 100% and the phone battery is at 78%. Not sure whats going on. Accubattery shows 57% health after about a week of use. I have a battery replacement ordered...

First signs of the phone going to catch fire like my Z force did.
Took an update and it caused massive issues. Battery life was horrible and started to over heat. Not long later sitting at the Android set up screen about 1% battery drain per minute. Motorola said it's normal and no issues. Phones frame was getting to 90c again Motorola said ots normal and withen spec. Then other caught fire. Can't comment any more due to legal process. I'm just posting stuff I already have when I first seen the issues.
Be careful. Lucky at that point I was charging my phone in a metal pot. So if you see a huge battery drain and start to see overheating and reboots keep it in a metal pot. The pot is what saved my house from burning down.

I think that the incipio mod is the problem, O noted the same behavior using the mod, some weeks ago I purchased the turbo mod and it works better than the incipio.

I'm having the very same problem and will send the phone in for battery replacement.
Hundreds of users are complaining over there in the Lenovo Forums about this problem that came with 7.1.1.
Motorla recommended one user to clear the cache partition, but I don't think this will finally solve the 7.1.1 problems.
Let's wait for a software fix from Lenovo/Motorola or hope for Android 8.0/OREO

I think It's from some weird bug from 7.1.1
I got this problem after flashed 7.1.1 and now, it's in the warranty for battery replacement :/
and with my experience, nothing will fix if you flash back to 7.0.0
Check this too:
https://forum.xda-developers.com/moto-z/help/issue-2-crazy-battery-behaviours-t3680766

I replaced my battery. Before the battery would give 1.5-2 hours screen on time (57 percent drain an hour). Now I'm getting 4-5 hours of screen on time (17 percent drain an hour). Both measurements are on the same Android version 7.1.1 and same settings

Battery life and warranty

Hello
Recently the battery on my phone very quickly discharged.
The phone is after a hard reset without any applications installed.
When it is almost unused batteries lasts about 5 hours
android os 88%
phone idle 5%
display 4%
stanby mobile 3%
When surfing the Internet or make the call battery is discharged after 1-2 hours.
I'm going to send the phone for warranty repair in UK.
Has anyone had a similar problem?
How long will it take to repair it?
Looks like some application is using up lots off battery. Try resetting your phone, install apps one by one.. If student you lose battery life that's the culprit.

It's not an app that's using up battery life, it's the "Android OS" itself. Uninstalling apps would have a small effect.
Though I do recommend a factory reset, it could be a setting that is using up all this battery.
Battery usage when turned OFF???
I've seen something that really surprised me. I have two Razrs, nearly identically configured. One of them I turn off most of the week except when I need to tether. I charge it once a week.
I thought this was a fluke, but it's happening consistently since ICS:
It used to be when I charged the battery once a week, this phone was nearly completely charged and only took a minute or so to reach 100% charge.
Now under ICS, when I plug the phone in for charging once a week, the battery meter reads below 50% and takes a couple of hours to charge up to 100%.
What has changed with ICS?
Is there something still running when I turn the phone off now? It would seem to me that OFF should mean OFF.
Or, is the ICS battery meter more accurate? Or does the meter need to be reset to 0 somehow? I did do a factory reset after installing ICS.
Any shared wisdom would be greatly appreciated.

With those stats, there's nothing wrong with the battery. I've never seen the Android OS use more power than the display (doesn't make any sense why it should). There's something running intensely on your phone. The bloatware is considered part of the OS (motorola apps), try disabling some of them. Otherwise I'd suggest a factory reset/cache wipe but since you've already done that, try re-downloading the OTA and installing all over again

Not too happy with my V10 right now

I am a light phone user. I only make a few calls a week, and most of my phone activity is sending and receiving texts from my wife and a few co-workers a day. The problem I am having is either the battery in this phone stinks, or there is some process running it down quickly. I keep all network, GPS, bluetooth, syncing, turned off unless I use them. I have installed Greenify as I have on all of my Android devices. This morning, I have received one text. That is it.....have done nothing else on the phone, and started the day on a full charge. It has been up 3 hours and it is at 93%. yesterday, I sent and received about 4-5 texts and the phone went down to around 80 % during the same time period. That was with wifi on, but the phone is set to turn that off when the screen blanks. My phone is on Marshmallow and is unrooted. Is anybody else having the same problems with this phone?
No. I have been off charger for roughly 4 hours. About 1 hr phone calls on BT, 30 min playing games, several texts. 4 gmail accounts all set to sync. 90% battery left. On MM, probably 30 apps disabled. Best battery on a stock phone I have ever got.

Unless I can get the phone back to Lollipop, or somebody figures out how to root the phone with Marshmallow, I am stuck with it as it is. Today I sent and received a total of 20 texts, installed an app from the Playstore using wifi, used the mobile hotspot for about 5 minutes using mobile data, and made no calls. I turned off wifi and mobile data as soon as I stoppped using them. I also disabled background data. The phone is now at 64% charge. My HTC One Max would have still been over 90%.

Did you factory reset after the update? Did you 100% drain the battery and then recharge? Something seems to be off.

I hear you, but for some reason on this phone i had to drain 100% to get my battery back on track. Mine used to stay on 100% for over an hour. After a full discharge, it now displays accurately.

Just to add my $.02 to the mix. I to am having HORRIBLE battery life after updating to MM. I have factory reset once already and am planning on doing it again tonight because the battery life is bad after the update.
I have frozen a few of the VZW things, but I do use a lot of google stuff. I've already bought a couple of extra batteries as it seems that I'm going to get stuck somewhere without a charger, and my battery will go out completely .

Also, how long is your screen time-out? If it is a long time-out and getting notifications turns your backlight on, that might 'reduce the juice' significantly. Just another thing to check-off.

Greenify has no real effect unless you are rooted so I don't reccomend using it. Since you have Android M doze mode should be good enough to use. Also you probably only have legitimately received one text message, unless someone has confirmed that it isn't working. The main issue with Android M that I have is that sometimes phone calls will not go through on my phone, and that's really all there is for glitches on this phone so far.
I did a full factory reset from the recovery menu, then ran the battery down all the way and did a full recharge. So far, it is working MUCH better. Yesterday it was at 89% at the end of the day. All I did was send a few texts and play a few rounds of Skyforce 2014. Unlike the other day, it is not running down quickly while it is idle.
I have been off charge with little usage for 3 hours now and I am still at 100% but when I go to lunch and actually use my phone for social media and such I will burn through at least 25% in 30 to 40 minutes.

No! I do not do Facebook, Twitter, or any other social apps. The app is not on the phone. It has been on a few of my phones, but I always disable it. I am on day 3 now after the factory reset and running the battery all the way down, and that seems to have resolved my problem. I would recommend to anybody to try this if you are having the same problems I was!!
I've had horrible battery since MM update. I left it at 100% last night about 1130am and this morning at around 800am the battery was down to 89%. I even left gmail and hangouts unoptimized. I'm going to try going full 100% to 0 then see if that fixes it. If not, then I'll factory reset. I'll update... Hopefully someone figures out what is eating the battery. I loved this phone on Lollipop.....

G5 battery issues

Hi guys,
Just wanted to know if any of you have had these problems before I ask for a replacement.
I've had the phone for around 10 days now and I'm having to charge my phone twice a day, and it drops from 100% to 0% twice a day too. This is whilst i am at work as well, so i have the phone screen on for 3 hours max. Just now it dropped to 0% with 2 hours 5 minutes SoT. The phone basically doesnt charge at all if I use it, and I am not getting anywhere near 80% charge in 30 minutes? (Bought anker quick charge 3.0 charger).
Any advice would be appreciated,
Cheers
Check to see whats using the battery... I had mine drop like a rock today & I found that Maps had used 57% & I never used the map today. Didnt change any setting or anything yet, but from a quick google search this seems to be an issue.

The only things using the battery were Screen, Phone idle and Phone Standby. I have asked for a replacement which will come later anyway, as the phone used to overheat for no reason. So hopefully the new one has no problems.

I kept getting notifications asking to turn on my location and found that Google location history kept polling my location every 30 minutes. Maybe you can see if you have that on.

Quick update, I was given a replacement phone as soon as I reported the problems to EE. They classed the phone as faulty. I have exactly the same apps on the new phone and it is charging a lot faster, and the battery is lasting longer too, so don't think an app was causing the issues on the first phone

LG G5 (RS988) Battery Won't Hold Charge - Please Help!

I bought my LG G5 new last November (2017). Ever since last week the battery can't hold a charge for more than a few hours. It goes from 100% to dead two to three times a day. Before this disturbing trend, my normal usage would get a full day off a full charge.
A normal day for me is listening to a music player w/ headphones, making sure the screen in on standby. If the screen isn't off I'm just doing light web browsing, like checking forums, searching eBay, reading articles...just really basic web browser stuff. I make sure to keep the brightness at 40-50% on average; close to zero at night.
Anyone have an idea why this happening and how to remedy?
Thanks.
The battery is most likely no longer able to hold a charge, like you described

After the last OTA update mine suddenly started to do the same thing. I bought 2 batteries online () but they did the same thing. So I got the unlock file from LG and installed twrp and lineage 15.01. Battery improved some. Installed greenify and now i get almost all day. I still swap between 4 batteries. Each lasts about 8 hours and I always take an extra battery with me when i leave home and plug in car charger.

What's the OTA update? If it doesn't download automatically that's not the reason. Plus, this just started happening like 5-6 days ago.
I ordered a new battery yesterday. I couldn't find one that said it was compatible with the RS988; hopefully it works with my model.
Someone suggested I test my battery with a multimeter. I actually have one.. can't belive I didn't think of that. Also, never heard of greenify. I'll have to check it out.
Over the air updates are pushed out by the carrier or manufacturers. I don't know the last version but they can be automatic so you might have it. I found another thread on this https://forum.xda-developers.com/lg-g5/how-to/rs988-software-update-21c-t3663768
So I got the new battery in the mail and no dice, it still is chewing right through it. It doesn't seem as drastic as it was initially, but I still need to charge it again in the mid-late afternoon.
I think it could the charger. Shortly after i got the phone the battery wasn't holding so well. Then I left the stock charger at a friends. I didn't have time to go pick it up, so I bought a replacement and all of a sudden the battery was holding all day. Then after a while that new charger wasn't holding the battery, so I switched back to the stock one and it was holding it all day again. So chargers have alot to do with battery performance. I ordered another one; hopefully that fixes the problem.
It was the USB-C cable. I bought a new one and I'm getting a full 24 hrs of charge.

Extreme Battery Drain after OneUI 2.1 / September Security update

Hello all, it's been a while since I've posted but this is quite a serious issue and could some guidance. A few weeks ago, I finally updated my Galaxy S9+ to Android 10 after being on 8.0 for so long and it's been a decent update so far. I had gripes with SoT not being the greatest but it was tolerable. Last night, I received an update for my phone and I installed it. Didn't think too much of it and continued on. I charged from my phone to ~87% today, used it lightly while working. By the end of my shift, I had 50% left.
I left the house to go for a 81 minute walk with 47%. I usually don't worry about having enough juice to make it back home but I experienced the worst battery drain I've had with this device so far. During my 90 min walk I:
listened to Spotify using my Galaxy Buds (one ended up dying towards the end because I forgot to charge them)
Checked Instagram occasionally and responded to some texts
Took 2 pics in Snapchat
Had a short video call on Messenger
It was right after the video call I noticed my battery was at 17%, which I thought was very strange. I don't leave apps running in the background for long and I have a habit of closing them out when not actively using them and I noticed the battery kept on draining despite there being no apps open besides Spotify.
Turned on the medium power saving and within a few minutes, I was at 5%. Decided to kill everything and pit my device on max power saving mode for the first time since I've owned the device. By the time I was home, my phone was at 1%.
I'm really baffled at how the battery drained at an exponential rate. I'm a medium user and I've had this phone since late 2018. Never leave location services on, never used AOD, and used the FHD display instead of QHD along with dark mode.
I'm hoping today was just an outlier as I want to keep this phone for another 2 years, but if this happens on a consistent basis I'm gonna have to start searching for a new device.
In the meantime, I have charged my phone to a 100% and disconnected the phone and observed the following:
Within 2 minutes of disconnecting, battery went from 100 - 98%. Not a good sign considering it was just idling
The battery continue to drain every other minute and I could see the battery go down on each unlock
Wiped the cache partition and I went from 93 to 94% for a brief moment prior to the phone going back to the same pattern
This is very worrisome to me as I don't believe the phone will last until midnight, I'm wondering if it's possible to roll back to the previous update.
TL;DR - After the update yesterday, the battery drained at an exponential rate despite light to medium usage
Also, here's some screenshots of my battery usage

I know this isn't the answer you are looking for, but all I can do is suggest changing the battery and doing a full, stock firmware flash via Odin to completely wipe your phone.
I recently replaced my phone's battery and did flash the firmware and my battery is really hanging in there. My battery was also 2 years old and before, I would get about 3h SOT when I play a game (and I do a lot). Now, I'm getting 5h SOT no problem with about 2-3h gaming included, so I really do suggest a battery change. I'm thinking you could be able to squeeze another 1 or 2 years into this amazing phone.
