hello, is it a common problem? or is there a problem with mine? Not actually very hot, but hotter than the room temperature
I have the same thing, especially if the handset is charging through USB from my laptop.
I don't recharge from USB as I've read that it is bad for the battery. Again, not very hot. Also slightly hot when using UiFi for a very long time, or playing a lot. I guess it's normal. Being used a lot ... :-? I don't know, just asking
Hi georgeono,
I can't remember how to disable charging on connectivity to the PC. Can you please point that out to me?
Many thanks,
Ayman
Hey, I already found it. Don't bother yourself )
It's Settings -> All Settings -> System Tab -> Power -> Battery Tab
And why would charging through USB be bad??
well, to make a good charge, you should leave the phone 5-6 hours (even though the led is green, I let it even up to 10 hours (charging at night)). When at PC, I don't think you all the time keep the phone pluged. In order to make a good charge, the battery has to be nearly empty (new phones work well without this waiting, but still, in time ... you see the differences). And I don't think anyone waits for his phone to be empty to connect via USB. .
I previously had an SE 850i (4 years used). Always charged when battery was empty, charged about 6 hours, and now, in stand-by, the battery resists 10-11 days. That is something ... 4 years!!!
It's normal,the battery heats up when under heavy use/if charged. It's nothing to worry about
Thanks. Had the same opinion, but still asked. never know ...

This is a myth for lithium rechargeables
Lithium type batteries do not mind when they are charged, and topping them up is perfectly fine. Topping up little but often is probably going to extend the life of the battery if anything and not reduce it, why? The biggest killer of lithium type batteries is heat, and giving it a charge from nothing to the maximum means it gets opportunity to get very warm which ages it, whereas lots of little charges will not up the temperature nearly as much.
Also another myth, you can't damage lithium batteries by overcharging them, this is because the current is stopped when they are fully charged as if it wasn't they would explode!
Lithium batteries also have a use by date, and as soon as they are made they start to age and reduce in capacity, so you are better off using and abusing the battery to get as much from it as you can, as age and heat will probably kill it first.

My device is very hot when charging... Much hotter than my Touch Pro2 gets
i experienced a few times that my compact V (topaz model from T-mobile) freezes while using navigation software in the car, meanwhile charging... When i took my phone from the holder, it was extremely hot! After holding it in front of the airco for a while and restarting, everything worked fine again. Anyone else with the same problem?
I found out, that using GPS uses the battery extremely.
It drains with about 300 mA, while normal usage ist at <70-80 mA and standby even a lot less.
Additionally I found out, that the device becomes sluggish due to processor-Usage of nearly 100% (while using gps).
That might be what you are seeing.
Regards Thorsten
talking about GPS usage, when ever i'm on iGo when i minimize it to make a phone call, it doesnt connects. i had to exit iGO n wait a while before it is available to dail. or a quick soft resets solve it.
any of u have the same problem?

similar problem here - igo gets disconnected from gps receiver because it's getting hot !
Hi, I have Darky 10.1 installed right now. And it gets really hot while surfing the next on 3G network, charging or using the phone normal way. According to Spare Parts app my battery temp is around 38-45 degrees. is it normal ?
Share your temps please, especialy on Custom ROMS
Depends on your ambient temps but yes its pretty normal.. right now im getting 36c.. When I forgot and left my phone infront of the AC battery temp went as low as 22c
Yeah, it's normal - the battery usually runs at 30 to 50 degrees. Can get hotter if charging while playing, watching videos or browsing. So, don't worry - I've had mine pretty hot while watching hd movies for several hours non-stop while charging - the only thing that happened was the notification that the phone stopped charging coz the battery temperature was too high. Of course, this can't be good for the battery and the phone but I'm talking for temperatures way above 45 degrees - 45 is perfectly safe and harmless.
So i have been noticing my Tab 3 8.0 has been having issues charging and draining battery pretty fast. Today im noticing in this one battery widget that it initially plugged in charges good then the charge rate drops off (note I'm using the charging cable and wall adapter it came with.) Then earlier this morning it drained down to 40% in an hour after being charged 100% overnight all i was doing on the device was surfing tapatalk/facebook and messaging a group of friends. Iv also noticed plugging and unplugging the micro usb from the device will get it to charge at a higher rate but then drop again.
I've also noticed after the system update, kitkat i think it was i noticed my battery lift become a lot less than it originally was. I have the my screen brightness set at the min setting all the time yet the device shows 70% battery usage from the screen in the settings/battery tab.
Not sure if anyone hss encountered this issue before. I'm at a loss and almost ready to contact samsung to have them look the device over.
I tried posting a screen shot of what im talking about but i do not have a high enough post count
Edit: it showed about 39% charged i unplugged it for a min and it jumped to 99% and lost 6% charge in a few min and its bouncing back and forth between 90s and 30s%
EDITEDIT: Fixed the jumping around battery % with a cache wipe/factory reset. New problem I burned 80% of my battery in about 2 hours of light usage screen a min brightness all power savings on while only on facebook messenger.

Hello, I hope all of you are well and I can get a reply or suggestion from you guys for this.
I have a new P20Pro. Bought it on the end of October.
The battery life is absolutely great with almost two full days of usage.
The issue I got is this.
When I am using my phone and it comes on the last 10% of battery it staets droping by 2-3% immediately. So it will go from 10 to 7 and then 4 and then 2 and immediately shut down.
The whole thing would happen to 3-4 mins in total.
When it gets to 2-3% it says it will shut down in 30secs and never goes to the last 1% or 0%. The other thing that bothers me, connected with what I said before, is that when I connect it to the charger when it turns off completetly, usually starts charging from 2-3%, almost never starting from 0. Today for example turned down when it was 4% and started charging from 12%>
I have tried almost everything, recalibrating the battery, doing the charging cycle correctly, wiping the cache and factory resetting it and also chenging the settings but nothing seems to be working.
Any ideas please ?
What you describe is usually a battery problem on older phones and a new battery remedies that. Mine us also in a bit of hurry ti switch off below 15% so I make sure to keep my juice always relatively high. I might take it for replacement of battery in a few months to have a new one after 500-600 cycles [emoji4]

Mine starts shutting down at 6% I think! It's caught me out a few times, thinking I had at least another 20 minutes.
I can't complain about the battery life though so no big deal really. Conversely when I unplug from a full night's charge it can stay at 100% for ages whilst using it.
I'm guessing either calibration is a bit off or EMUI is really going the extra mile to protect your battery from being damaged by draining too low.
almost 2 full days usage?
man I barely get one day, the battery is being drained quite quick
I just switched from OnePlus 5T to P20 Pro, and the battery life of the first is way ahead (and recharges much faster)
maybe there's a problem with my p20pro?

Hi!
Follow the below steps.
Phone manager>Do optimise>tap on battery icon>Optimise battery usage. And dont let any apps to run in background. Using auto start manager you can control the apps which are running in the background.
and please post the battery usage details and check which app is consuming more battery & kill the apps which are consuming more battery
Hopefully it would help.

Hi Thanks for your help
I will definitely do it and will keep yous updated
Meanwhile, let me bring something else: My phone doesn't supercharge. Even when I use the original cable + charger (and plugged straight into the wall) it doesn't fast charge. Doesn't display that it is being supercharged or something and it will take about 3 hours to finish charging.
This is a brand new phone which I got last week.
I used to have an OnePlus 5T which recharges pretty quick but this P20 Pro, although it is a beautiful phone, charges like my old Moto X.
Anything else I need to setup in order to enable supercharge?

Download Ampere from the app store and see what the charging rate is.
When almost empty I get a rate of 4200mA ish.
The more it charges the lower the charging rate.

When I use the original chargers from Huawei, it won't get past 1800mA
Then I went to visit a friend who got a Mate 20 Lite, he has a fast charger and I tested his in my p20pro and it went to ~2300mA (and then it displays in my phone "fast charge"). However, if we use on his phone, it will go more than 3500mA
The supercharger won't come by default in the box? I'm asking because when I got at home I checked the output of my recharger and it shows 4.5-5v -> 2A, it seems it isn't the fast/super charger
Hi there! What you have described with the battery percentage going to 3% and then immediately to 0% is an issue on ALL Huawei phones. I had previously owned a P10 LITE, a Honor 7C, Huawei P20 PRO and Mate 20 Pro. They all do this. I suspect it has something to do with the reserved battery percentage . It shuts down quickly so that it can keep 2 % and not drain completly. I do not know the benefit of this but all phones do it, however Huawei's software implementation is so poor that it actually displays wrong percentages. It has nothing to do with the battery being old. They do it straight out of the box and ufortunately do not know of any solution to this.
Just an update:
I had a chat with the store which sent me the phone and then they sent me the correct charger with supercharge.
Now it works well and on Ampere it shows 4.5A

Goto Phone Manager touch power saving->Optimize.Phone Manager will rapidly identify apps or features that are rapidly drainning the battery.Touch the Optimize button net to each or feartures to disable it and start saving power.You can touch Recover to re-enable the app or feature.When you remove an app from the protected apps list,your phone will close the app automatically when you turn off the screen to save batterry.
Hi guys,
I keep having weird battery behaviour which led me to believe, that the battery is not properly calibrated:
When charged to 100%, the phone usually stays at 100% for a few hours depending on usage. Around 40% however it keeps dropping 1% every 2-3 seconds until after a few minutes it is drained completely and switches off.
Did anyone else notice that kind of behaviour? (Some guys on Reddit are facing the same issues)
And does anyone know a fix except waiting for a custom rom?
Thanks and all the best.
Jay

Same here, I didn't notice the battery after 40% but the phone stays at 100% for a really long time, I played Honkai Impact at max setting and it still manages to stay at 100% for an hour, mb it's software issue, I'm on 12.5.7 Global btw.
I didn't experienced that kind of issue. 12.5.13.0 EEA here.
you have to calibrate the battery.
- discharge the battery until the phone turns off
- with a slow charger (10 / 25w) charge the mobile OFF
- once it reaches 100% (1-2 hrs) wait another 2 hours.
- Power up and test.
This method usually solves this problem, it is important to use a slow charger and only use the 120w one when it is really necessary. It seems that some batteries have not been properly calibrated

Thanks, I'll try to do that with a slow charger.
After it reached 100% still keep the phone on charge for the next two hours or just wait two hours to power up?

Still keep the phone on charge min 2 hours or more (ex. When you sleep) next you can turn on

For me viper4android it's much better if you use wired headphones. I tried to use Dolby but it's not the same.
I'm on 12.5.13.0 EEA, same problem. Phone stay at 100% for hours, then when power dropped to 35-30% weird thing happened, it keeps dropping 1% every 2-3 seconds until after a few minutes it is drained completely and switches off.
Then it takes 5-10 minutes to start again
I will try to calibrate the battery tonight
Hi, I was facing a similar issue.
I have used 3 chargers. 120W (stock), 10W (samsung), 65W (Anker). I was worried about my battery life, so decided to ditch the 120W charger which was also not giving me a good enough battery life, considering its a 5000 mah phone.
Im not paid by anker or something, but I saw a major difference between SOT compared with stock and samsung charger as well. I dont know why this is working out so well, but im getting 7+Hrs SOT easily, on heavy usage. AndI have been getting consistent results from the past week since i switched to anker. I genuinely dont know why or how this is working. But if it works, it works.
Im assuming due to the 120W quick charge, the battery calibration gets messed up. But idk how to explain the longer duration of SOT on the anker charger.
Ps. I dont use 5G

yes, I don't think you are very far from the problem. I also think that charging the mobile at 120w spoils the calibration of the battery so I use it only at specific times. I use a standard 15w charger (approx 2hrs)
3 days later It looks like calibration sorted my issues. Now battery behaves as is should.
So calibration is very recommended if battery plays up
I recently purchased this cell phone, and I am experiencing this problem. I have disabled almost everything, and uninstalled blotware. Should I calibrate the battery to improve battery drain?

Please read my reply in this thread, that will extend the battery drastically.
im facing this problem with this phone as well but also something else: after the battery drops to 18-20% it then discharges very very quickly to a point where in a matter of 5-10 minutes of use it's down to 0%. is this normal or is it another one of those side effects that their trashy fraudulent scamming xiaomi battery measurement causes?
will another rom fix these issues or are we stuck with them in this phone i rapidly regret getting?
I'm also facing the same issue, below 25% to 0% it drains like a liquid, I attached the screen record

mine got fixed (at least for now) by calibrating the battery (leave it to discharge and turn off - try to turn on again until it wont - charge to 100% with phone off) i'll see how long this lasts and update
Ya i did it for now it is fixed might be a temporary fix. I'll post here if it happens again
Same problem at first month, 100 - 99 became shorter and shorter while charging cycle increasing.
