While testing charging on the XZ2 I found out that we use the new Qnovo Charging technology which tries to reduce the usage of a CCCV point but adaptive charging.
Another really strange phenomenon was the maximum Voltage.
4.331V
After checking the disassembly video I saw the battery which stated 4.4V....
Sooo... Time for crowdsourcing!
I need your help guys.
Use this app: https://play.google.com/store/apps/details?id=kr.hwangti.batterylog
BatteryLog, or Ampere, or whichever method you want and take a good look at battery Voltage when you reach around 97-100%
Is the 4.4V on the Battery a fluke? Or do some batteries reach different max Voltage? Let's find out!

Hm. I haven't fully charged the XZ2 yet, but on my LG V20 it also says 4.4V. So I decided to open the back and take out the battery (removable batteries! Such a great thing!) and found Li-Ion Battery 3.85V, and lower down some chinese characters and then 4.40V. No idea what that's supposed to mean... maximum voltage? Anyway, the LG V20 also seems to top out at 4.4V.

Hi guys,
I charged battery till fully charged yesterday and I went to flash a firmware upgrade which took about 15 minutes in total and thereafter when my phone restarted, it showed me 39%, a huge 61% drop during this process and I checked the battery voltages in fastboot getvar all and using gsam battery app, it still showed me 4.2-4.3V which is usually a full charged battery. Now after charging a while, it suddenly goes back to 100%, any idea is this normal? This is the first time this is happening.
Hope to get some help and advice around here, thanks guys.
Screenshots after charging over an hour:
Just plugged into charger:

You need to re-calibrate your battery. There are a few different ways I've read people doing it. I usually just let it totally drain, then charge it to full again without messing around with it. You may want to search for a proper method.

Value changes, charge and check again.
Quick tip: If you're charging to 100 stop doing it. If you let your battery drop below 10% stop doing it. If you play on charge stop doing. It'll hit the battery life very slowly.
So i shouldnt charge beyond 100?
I normally charge overnight
Sent from my C6902
Mine had 288.something
Then it deep discharged and now it has 310.something again.
I would not care too much about this value to be honest.
Stop charging overnight. It hurts the battery and reduces cycles. If you don't charge to 100 and leave it you'll get thrice the battery lifetime (should last 800+ cycles).
The values keep flitting, try charging the phone and see if value increases.
Hi,
Im having trouble gaming with my Teclast X98 Air 3G C5J6 while charging.
When I'm not charging it is working fine.
But when charging (with 2.5A charger) I get much higher temperatures:

I get no thermal throttling, it just goes black after a few minutes. It shuts down, and I have to start it up again.
I'm thinking of doing this: https://www.youtube.com/watch?v=7GSfvAbrVVo
Will this help or is it related to something other than the CPU temp?
Thank you!
When you're charging your tablet, the battery inside gets warm so the CPU gets overheating. When i've installed cooper plate it's getting warm less.
I'm not 100% sure what's actually overheating, and id like to know to find a better solution, but you can use a 2 amp charger, or use a long cable to limit the amps and you should be able to stay right under the threshold to be able to game and charge the tablet. I use these cables with the stock charger and I can game while charging (the 6 foot model) http://www.monoprice.com/Product?p_id=9762
It takes 3 hours charging with orijinal adapter. İs that normal?

Your charging voltage and current seems to be too low for 43% battery level.
I have two "chargers" supplied with my P9 - one with UK pins, the other with AU pins. Both are rated 5V and 2A. I tried both.
When I charge at 47% level, the voltage is 4.05V for both chargers, and the current is 1440mA with one charger, and 1800mA with the other. Why the difference I don't know.
I also use the Ampere application, and did not have any other app running. Wi-Fi was on.
Personally, I would be happy with 3 hour charging. I believe it is the best for the longest battery life. But if you need fast charging, you need 9V "charger". There is a separate thread for fast charging.
cheers
Has this been resolved? Encountering the same issue.
Tried factory resetting to no avail. Looking into the option of swapping it to a new unit
in fast charging,it take 50 minutes to go from 5% to 90%
Hi, I had a little accident with my maze recently. Now I need to replace phone's battery but the problem is I don't know what battery to use. I've searched through loads of batteries and the voltage which is 3.85 does match the capacity which is close to 4000mAh is okay too, but the battery connectors don't seem to be exact. Anyway I hope someone can help me and possibly future users aswell!
Can you post the information on the body of your Maze Alpha battery? It would be helpful to post images of the battery and the connector.
same problem
hi, ive got the same problem, and have to remove the battery but can't source a new one, the battery is 6.5 mm wide, 8.6 mm long and 4 mm thick, i've attached links to photos of the connecter, thanks in advance for any help
