If you have ever wondered about the battery in your Z2 Force especially after your device has started dying at different battery percentages, well, this is what happens. The first time my Z2 Force died was about 10 days ago and the battery was at 38%. It died when I opened the camera app. The second time it died was with 46% battery life remaining. After this it would die with 98% battery. After doing some research and reading all of the post at the Lenovo forum about the battery issues with our device I decided to order a Moto Battery from Amazon and I installed it earlier this evening. I am letting it charge to 100% before I power up my device and then I am going to use my Z2 until it is completely dead and then recharge it again to calibrate the battery. Here are some pics of what the original battery looked like. The battery was broken into several pieces inside its wrapper and you can see where it had been swelling over and over. Ive had this Z2 since August of 2018. The original battery made it just over a year before I started having the random shutdown issue. I have attached a link to the battery I ordered in case anyone needs a recommendation. This battery comes with the tool kit to disassemble to device but the only thing I did was remove and replace the battery and it took me a total of about 25 minutes. I did use a hair drier to assist with the adhesive but I did not feel it was absolutely necessary.

Just a quick update about the new battery.
When I installed the battery it was fully discharged to 0%. I plugged in the original USB-C cable and the original Moto Turbo Charger that came in the box when the device was new.
Before I powered up my device with the new battery I let it charge to 100% and when it reached full I set a timer to let my Z2 Force stay on the charger for one hour.
When that hour was up I turned my device on and went through all the things I could remember that would cause it to shut down. I couldn't make it shut down with the new battery.
With the first charge my SoT was 7:18. That was a surprise for sure. When my device was new I would frequently get over 6hrs of SoT.

So I've been having issues with battery life and my charging.
When I woke up this morning my phone was at 1%. I went ahead and played with it till it died. I kept it turned off and let it charge for about 2.5 hours or so. I would think that it would be close to fully charge. The battery charging icon when phone was off made it seem that way, but when I turn my phone on it's only at 40%. I turn it back off and let it charge for another 1.5hr while i'm at the gym. Come home to find that it's only charged up to 46% since then.
This is a brand new, official samsung battery. Came with the Samsung spare battery charger. Similar things have happened with a 2nd spare battery i've bought. None of these issues happened when I was using my original battery though.
Do you think it's the phone or the battery itself? I'm leaning towards phone
My phone doesn't charges above 70+,if i remove the battery and reinsert it it shows 92% after that it charges normally till 100%,again the same thing is continued in next session of charging. ..I tried calibrating the battery by removing the battery and hold the power on button for 60+ seconds and also tried the battery calibrating app..no use at ol...one thing is, if a use the mobile continuously it charges very slowly after 70+,if its not used again it stops charging but indigates as charging,till 70% charging is smooth and fast...pls help me to troubleshoot this thing plzzzz... :crying:
sounds like you might need a new battery
Yes, you need a new one.
Most batteries from more than a year ago starting to have this problem after updating to 6.0.1
The update stress the battery too much and if your battery is more than a year old, will likely be damaged after that stress.
Yes, samsung batteries are less than cr*p.
Context:
My dear LG G4 started having some battery issues this summer: it would sometimes turn off at around 15%, usually if I tried using the camera app. It would turn back on, at <10%. Left idle, it would actually increase the battery %.
About 1 month ago (maybe a bit more), the problem started to increase: it would turn off at ~40% - but not always, rarely. Last week, this happened everytime. Sometimes it would turn on back with ~5%, sometimes with 30%. Anyway, weird behaviour.
So I decided to buy a new battery. Can't be sure it's 100% genuine, but reviews say it should be fine (looks 99% like the old one).
Hoping it would finally solve my issues, I put the new battery in the phone. 5% charged - well, it's new, ok, np -> charge it to 100% and then go out to lunch.
The drain was awful, in less than 30 minutes it was at 75% (moderate usage at most). When it hit 74% it turned off. Problem is, this won't even turn back on. Got back to the office, plugged in charger - battery still reported 74%, phone turned on. Disconnected the charger, 1 minute later, phone turns off.
It's like when it hits 74%, it stops working.
Any ideas? Phone is still in warranty for a month, but not sure if this kind of problem is covered.
It's also my second G4, first one was replaced due to bootloop in summer 2016.
Download Accubattery app from Play Store, for the old battery , check it's health, repeat for the new battery.
My 2.5 year old LG G4 still has bad battery life because you know the SD 808 heats up quickly specially on hot summers or while charging, the battery's no1 enemy would be heat! So with the help of the app , I found the battery health had depreciated to 69% of it's 3000 mAh (that is 2069 mAh ) If your battery is new , I think your battery health should be 90%-100% in the Accubattery app!
Buy a new battery its done
Wonder if anyone might know whether the fault is with Battery or internal charging circuit.
The watch wouldn't charge so eventually died
Occasional connection to charger showed a battery with lightning bolt symbol
Still won't charge
or boot up now.
No longer shows the battery with a lightning bolt icon
Assume battery is completely flat.
I have 3 official charging docks and multiple power sources - none work.
I stripped the watch down and tried my son's battery without removing his battery and the watch booted up fine.
But I can't risk taking sons battery out as it seems to damage them.
With new 3100 watches around the corner and already own the HW2 I don't really want to spend £20 on a new battery for a 3-year-old watch if it turns out to be the internal charging circuit
Any suggestions
Hi, something like this happened to me about a few months ago, same symptom no power and the Lightning bolt, I used a 500 mha charger (not the original huawei charger, while it delivers 2.0 mha ) and left the watch there all day and all night and checked on it later the next day and it was fully charged and had powered up on its own. I didn't open it up as you did. anyway l think that this happened due to l had not used the watch for months but now even if l don't wear it l still power it on once in a while and charge it so the battery won"t go completely dead.
A few days ago my Z2 started turning off. When trying to turn back on, 0% battery. Plug into charger and instantly shows 32%, 6x% or 7x%. Tried the whole recalibration voodoo of charge til full + 1 hr, drain down to shutdown. Charge to 100%+1hr... but no. Did a restore hoping I had a bugged app but just happened again with 32% remaining. Do any of these battery apps help or is it just ****ed.

This is what happens when the battery fails inside our device. I just replaced the battery in my Z2 Force about a month ago. When I removed the display on mine you could visually see the battery was damaged. Once I disconnected the battery and removed it from my device I could bend and fold the battery in half. It was swollen and cracked in several places.
I picked up a new battery along with a tool kit from Amazon for under $15.00. The kit I ordered had an original Moto battery in it.
