Battery problem - Huawei P20 Questions & Answers

Hi, today I have seen one problem and I wanna share with you. I noticed that when my phone battery reaches 13%, it starts rapidly to decrease the percentage, which is about one percent in 5-10 seconds. Then, on 3% the notification pops out that the device will turn off within 30 seconds, but turns off after 5. When it finally discharges and connects to the charger it starts charging and almost immediately goes from 1 to 13 percent. Does anyone of you have this kind of problem, and if so, how did you solve it, and if not, does anyone have a solution?

[Q] HOS random shutting down - battery problem

Hi there, I would like to solve the problem with my HTC One S S4. From the OTA update to Jelly Bean my phone started to do unexpecting actions. First of all, it started to dischranging and charging very quickly. When I have for example 15% of battery, after 30 seconds phone says I have about 9% and in the next 15 seconds I am out of battery power. The same thing is charging. I am charging battery for an hour to charge about 30% and then in the next 5 minutes it´s charget to 100. That gives me no sense.
The second thing is random shutting down. I noticed it´s more sensitive to shutdown when I want to do something with my SIM card (calling, accesing in mobile internet, but that´s not the rule). After shut down I have significantly less battery power ( from 65% I have about 20%). Sometimes it counts wrong and I have more power then a few minutes before (not 20 but for example 32).
I have flashed Recovery and Fastboot, loaded Custom ROMs MaximuS 2.5 and Trickdroid 9.1, but that didn´t help.
How can I fix that ? Thank you

[Q] Battery not charging

Hi guys
Since two days I'm having a weird battery issue.
My note is not charging beyond 60% although the battery is charging properly till that with a standard charger. But as soon as I switch to fast charging and restart my device, it shows 0% charging while switched off. Then when I restart my device it shows 0% but starts to charge really really quick till 50% in just 5 minutes or so. But still never charges beyond 60%.
Can anyone please tell me what could be the issue. I've tried wiping everything and switched rom but nothing's helping.
Is it battery problem or charging port problem?
Please help.
I'm having the same problem with my phone, just started the other day.

Battery issue, software or hardware?

Hello,
I bought a second hand S6, and after some while I noticed a battery issue.
While discharging, everyting is normal until about 11-12%, when it drops to 5% and then continues like normal, 4-3-2-1-shutdown.
If I put the charger even for a second in any percentage below 5% it jumps to 8-9% , and then contunues the discharge from there without missing capacity.
If again I continue to charge without disconnecting, if goes lets say from 1% to 8% instantly and then continues charging like normal.
Is this normal for an old phone? Or can I fix it somehow?
I had never noticed anything like that in any of my android phones before, ever 3 years old.
I have already deleted battery stats, and performed 2-3 times full charge/discharge cycles, without results
The ROM is original 6.0.1 rooted.
Hello,
Tried at 100% and stayed at 100%
Should I try at 10% or 1% ?

It happens for me too. It's just Samsung's failure. Sometimes my battery jumps %1 to %17 when i plug the charger.
To be honest, you can't do anything about it.
I did the proceadure at 14% it dropped to 0% after some seconds and then shut down.
I charged it OFF but when it reached 95% went to 100% in seconds.
When I unplug at 100% and wait 5 minutes (always OFF) at next connection to charger showed 95%.
So it took me 1 hour of intermitted charges to reach 100% and stay there.
We'll see what happens next. I'll keep you updated.

Galaxy Fold Z2 battery dropping to zero from 50%

Hey fourm, sorry for the long read but if anyone is technically savvy with batteries or voltages/electrical components please read! this might not be specific to a Fold but any device may suffer from what my device is suffering from.
I have recently had issues with my Galaxy Fold Z2 and it unexpectedly dropping to 0% charge, the first time this happened yesterday i was in an application and was switching from the larger display into the smaller one, upon closing the display the phone shut down and i wasn't able to get anylife out of the phone except a vibration when holding the power button, but nothing on the screen. I had about 35% battery at the time but all of a sudden it was at 0, after putting it on the charger it spring back into life. Today however i experienced an even worse problem... My battery was around 55% and i was connecting my phone to my cars bluetooth and importing contacts to the cars console, suddenly the battery went from 55% down to 9% instantly! i was shocked and took a screenshot of the battery graph showing its gradual decline from 100% to 55% but not to 9% to highlight the sudden drop, the battery status on the top of the notification bar was showing 9% all of a sudden but the graph wasnt just to actually see the drop! after that drop in battery it only took about a 30 seconds for that 9% of battery to jump down to 1% again in an instant fashion, following this only a few seconds later it shut down.I was thinking it could just be a dodgy battery for whatever reason but after trying to charge my phone after this sudden crash from 55%-9%-Flat i was unable to charge it up. The phone would signify that it was charging but not giving me a percentage, it would show the charging animation (the animation you get when phone is off and charging) but would only last for around 3-5 seconds before shutting off again and showing the charging icon again, and then shutting off again and rinse and repeat on a loop without charging but attempting too and resetting every few seconds! So for about an hour i couldnt get it to boot/charger properly and i almost gave up, but i decided to try a different charger, i was using the 25w supplied charger but i switched to a 15w older one and the phone ran the charge animation again however this time it identified the battery was charged at 55% rather that it not showing any charge level and resetting and trying again as it did before, this time it went right to 55% and from here the phone booted up and is working normally again!
Im really not sure whats wrong, im starting a process to send the phone back but i really wish to know whats wrong with my device! if anyone has any clue to this strange behaviour please let me know!
