Hi
I've this particular Note 8 for just a couple of days, but had previous Note 8s since 16th September.
Generally I leave them on a wireless charging stand overnight.
This morning, when I woke up I saw that during the night, whilst sitting on the stand, the battery had dropped from 100% to 92% and stayed at 92% for an hour or so until I got up, neither charging nor discharging. The screen hadn't come on when the battery dropped, and the battery temperature hadn't spiked significantly.

I've never seen this before - has anyone else? I've already had 2 faulty Note 8s, I really don't want to have to return this one too and get my 4th one....
Thanks
Could it be something to do with this?

Looking at it again, it looks like the battery level reported by the system was actually just catching up with the actual battery voltage - but why was the actual voltage so erratic and dropping whilst on the charger?

Huh?
Anyone else seen this erratic dropping battery voltage whilst on wireless charger?
Bump... It's happened again... Anyone....?
Thanks

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:

After charging over an hour, suddenly it shows up at 100%
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.
Hi xda
When i go to service tests screen and check the battery info screen. I am getting less than 3000 mAhr value....is my battery deteriorating?

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.
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
Anyone know where I can buy a new battery for the RP2? I've put mine through the ringer since I got my RP2 and this thing can't even hold a charge for half a day. 5 hours off the charger, less than 30 minutes of screen on time, with nothing eating away at the battery in the background, and I'm already down to 47%. I've been searching for a few days and the best I've found is used batteries on eBay.
Same. I also posted about if anyone knows of a store to purchase a new battery. Only seen them on eBay as used and no guarantee they aren't as used up as mine.
Also working for a replacement battery, Original/OEM, any leads ?
I am experiencing the same problem. After 2.5 years of RP2 operation I replaced the battery due to the fact that the smartphone began to turn off at low temperatures (about 0 degrees). And, if this behavior appeared after exactly one year of operation, that the smartphone could turn off at 15%, now it can turn off at 70%, even at room temperature.
A week ago I replaced the battery, which I purchased on Aliexpress, but it has only gotten worse. The smartphone can turn off at 30-40% of charge. This indicates that the battery is not able to deliver the necessary current. It is likely that its condition is used, but under the guise of a new one.

I have the Chinese phone with Origin OS, and I'm missing the features that many other modern smartphone brands have; optimized battery charging.
For example, it's not ideal for the battery's well being to always recharge the battery to 100 %, I would rather set it to 80 % like you can with Samsung and Sony units. I've read OnePlus and Apple can charge from 80 to 100% the last minutes before you usually climbs up in the morning, as this is supposed to be good for the battery.
Am I blind and have missed these battery settings for the X70 pro+ ? This is the only settings I can find.

Can't find that feature on the device. However, AccuBattery says the damage caused charging up to 100% is negligible if you're charging it from what they perceive is an optimum charge? That's something between 20–60%. Plus, the phone trickle-charges up from 90%. You can also find the charging speed slows down considerably and the phone warms down when charging 90–100% off the heat that's generated during charging up to 90%, 'fast-charging' the device. The app usually registers considerable 'battery wear' if you charge the phone when it is already 'charged enough'.
I don't even charge this phone overnight anymore.
Since it can charge so quickly I just put it on charge while I am showering and stuff in the morning. Then I remove it when it's around 80%
