Yea, I was going to put the sim in an old Moto I had ( the THREE z2's I used (family & friends had mildly used ones, long stories) all failed around the same time on battery failure. One of them the screen separated from the phone and I smelt it when I followed the **bleep**ty advice this forum had to offer.)
Just to remember that Moto needs a new ROM because the update screwed it up.

Is there a fix for this issue.love my z2 force now it keeps powering off ... before power off was at 45% now even at 85% it's being shut down low power ..any verdict on the fix or is the z2 junk?

There's no "fix" or "patch" if that is what you are asking. All you can do is follow the normal troubleshooting steps:
* Boot into Safe Mode and see how the phone performs. Is it better? The same? Then go from there.
* If necessary, backup all personal data and factory reset the phone. See how it performs with NO play store apps installed and no changes to any Settings. Is it better? The same?
* If that doesn't help, then either a replacement, repair or a new phone is the next step.
I know people get tired of seeing the same things posted all the time, bit those are the normal troubleshooting steps to follow.

An update on my warrenty, my old phone at the end of the work day would be at 70% the batery lasted about 5 months and then it would shut off at 80 %. My replacement phone WOW after work still at 90 % I charge it about every 3 days ( I am not a heavy user. Also I do NOT use the moto fast charger any more. ) They also gave me another month warrenty whitch has expired. Over 7 months so far and still going strong. I hope this keeps up now warrenty is over, Thank You Moto

I am new to this forum after having read up on z2 force battery drain and restart issues I am having with my ~1.5yr old phone. I have not seen a valid explanation for this battery drain issue so maybe the below can help others.
Based on my personal experimentation over the past week including safe mode operation, hardware reset and numerous app operations that cause the shutoff, I have deduced that this issue is related to the Battery Protection IC that is inside the battery. This IC determines if the battery or external charger is to provide power to the internal workings of the phone. If this IC "gets confused", then the phone shuts off unless there is an alternative power source. Since this issue can be recovered by plugging in the charger, this seems to make sense. Though since it continues to happen this tells me it is the IC and not software that is the root cause of this issue. So this gives me some hope that replacing the battery should fix the problem - unless the Battery Protection IC is faulty in the replacement. If not, then time to get a different phone.
I did review the teardown reports for this phone to better understand the Battery SubSystem and to verify which Battery Protection IC that is being used. After reviewing the datasheet for this IC and how it operates - it does seem to explain the issue. Though I can not explain why this IC is having an issue after a certain amount of time. Obviously I can't name the IC Manufacturer since I can't prove it is the source of the problem. But I suspect Lenovo/Motorola should be able to confirm this with relative ease...if they choose to identify the root cause.
Hope this helps.

Update: Last night phone got stuck in the power up boot loop. Left charging over night and had same issue this morning. Phone would turn on, get to the carrier logo and then shut off. Tried multiple times and would always do the same boot power up loop. I found the link below for a factory mode reset and wiped the data entirely (even personal data) after removing the SD Card and SIM card. So far it has powered up, connected to WiFi and gmail. So far so good. I was going to get a new phone but may not have to. This might be worth a try to see if it can get your phone to recover.

Hope this helps as it has saved me the headache of getting a new phone - so far.

Update 2: Ok...never mind update 1.
Looks like issue is still present though seems more software related than battery hardware issue as I had previously thought. I was able to boot up and use the phone a couple of times. Though it is back to the boot loop again with a wierd caveat. The power up graphics are stuck in a loop from "powered by andriod" to the "Lenovo" banner to the "Motorola" wording being displayed and back to the "powered by andriod" words. Connecting the charger during this loop has no impact on the software looping. It will react to the power button but gets stuck in the same software loop. My phone has 7.1.1 and it won't update to 8.x to see if that fixes anything.
So this Moto x2 is back to being a paperweight.
