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

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.

Shutdown when charging and gaming?

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

What's your Battery Voltage?

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.

Charging speed

The reviews said watt this and watt that so I expected big things
Plugged in seems to take 2 hours, forever, and so I bought a £60 wireless charger, and that is 90 mins to charge only 50%
Why has charging seemingly gone backwards? I know the battery is bigger but still.

It's just how Samsung works. No one understands this behaviour, I mean why does the phone almost costs 1000$ and doesn't even have like 20W/27W charging.
Even Xiaomi and other budget phones have this.

This would arguably be my biggest fault with the S10 tbh. I charged my phone at 16% today and it took 1hr and 40 mins to reach 100%. Its not a deal breaker given the batteries capacity but its not exactly "fast" either. Slightly off topic but it bugs me even more that theres no way to see what % your on or if the phone is even charging without turning on the display! This baffles me! Any other handset and you can easily see what % the charge is at when charging

Charging port is overheated. Issue with the charger.

Hello. I have an issue with the charging port since yesterday. I was in ROM RR and I wanted to charge my phone when i realize that the quick charging was not working and the charging time was super super slow. So I tried with different chargers but the same, and also I wiped and installed ROM Miui EU, thinking that it may be a software error; but no. Also I have cleaned the port with different thin objects and air, and I didn't have any solution.
In the Miui EU ROM I have the warning (warning of the photo) and the charging is as always very very slow, but if I charge the phone in recovery mode, I can charge the phone normally. So, I don't know what the problem might be, because I am able to charge the phone perfect in recovery mode but no in normal boot or when is off.
What can I do?

I advise you NOT to charge your device in recovery because there is no software protection. The slow charging is not an issue but a measure to prevent damage from overheating.
You should try with different cable/charger/power supply and clean better the charging port. If it doesn't work you may need to replace the pcb (search: mi 8 se charging port or dock connector)
