Question Problem with charging when completely discharged. - OnePlus 9 Pro

Hello from Ukraine guys!
Last times I have one problem with my phone.
When my phone completely discharged and power off after that I cann't charge it.
I tried different cables and power units without any success.
My phone doesn't charge after 5 or 10 or 30 minutes.
But when I go to recovery mode with battery icon on top right corner my phone charging well and I can see percentages of charge and after 5 minutes with 5% I can power on my phone without any issues. After that my phone charging very well, but if I will forget charge it before it completely discharged I have to go to recovery mode to charge it.
Anyone can help me with this strange problem?
I am using last global OxygenOS 12 C.48 with magisk (root).
Thanks.

If you already tried the MSM tool and clean flashed your device, and the issue is still happening, it seems like there is a weird "HW" issue. So, return the device if you still got a warranty on it.

Sadly i have the same issue. May i ask if you are rooted? Bootloader unlocked?
Since i am on c.48 my phone doesn't turn off when battery is too low (below 1%)
It can go at least 30 minutes in 1 % and this is not the intended functionality.
Battery needs to keep a reservoir to start charging. If it completely drains it damages itself quickly.
Another problem in my end is that c48 doesn't have offline charging (probably because of magisk).
Offline charging is a mode where the phone charges while is off and shows a battery icon.
So in my current state if my phone goes below 1% and i don't manually turn it off, it will forcefully shut down and after i plug it in it will try to turn on and shut down again unable to start the charge.
Only fix is boot fastboot mode (which uses really low power) and plug in for hours until the battery picks up some more voltage and then turn the phone on to charge normally.
Not hardware related. I have this for a while and i still get 4:30 to 5 hours SOT 100 to 1% and fast charge works ok.
Just don't let it go below 2% and shut it off until a fix comes up

Just fyi. This is a really bad practice to do regularly. Battery should not go below 15% often or it will ruin the battery life. See screeshot.
Since you have fast charge, it should be easy to charge it before going to sleep.

@Sergykm since there is no offline charging, try to never let it drain completely

I don't want do it and clean all devices's data, because all working fine except charging in "offline mode".

Yes, mate I have unlocked bootloader and magisk and c48. My problem is absolutely the same.
It is not a big problem, but sometimes I forget to charge it before it goes offline.
I'm glad to know this is not only my problem. Hope the problem will be fix in future.

[Q] samsung galaxy s3 charging problem

Hi,
Ive been having problems while charging my phone. Usually i charge my phone from 11 pm to 7 am and sometimes when i wake up in the morning the battery light is green and it reads as 100% battery charge but the moment i disconnect the wire it instantly drops to 30-50%. Is anyone else having these issues?
Are you stock?
I have not had this problem and charge pretty much same as you. I am stock rooted with a few apps disabled and only had the phone since October.
Try this app
Also I'm pretty sure you shouldn't let it charge for so long, it will hinder you battery life in the long run. At least that's what I have read.

Option 1 : Clear battery stats
Option 2 : Get a new battery and 24 hour charge
Option 3 : Let the battery DIE, drop it in the freezer for a few hours, then 12 - 24 hour charge it again. Doing this though MAY (not always does) cause the water indicator to trip. Easiest solution I found for that was I vacuum sealed my battery THEN dropped it in the freezer. No air, no moisture, no trip.

I would also recommend trying this app. I tried it out a few days ago and it does seem to help out quite a bit.
I find mine drops instantly to 99%. Even sometimes when I'm at 74% and if I don't use it at all, I will check back and it goes up to 78% :-/

[Q][NOOB]battery charging takes a long time

I've noticed that on my phone it will charge to about 90% and no further sometimes even if charging for 3 days.. But when I reboot it it gives me the actual percentage battery life. Try rebooting after charging it for an hour or 2, and see if the percentage suddenly jumps up. If not then you just need to get a new charger.
Try this and see if it helps.
>Drain the battery completely, till the point it shuts off.
>Take out battery.
>Charge the phone till 100% while it's switched off.
>Boot into recovery. Wipe the battery stats.
>Unplug the charger and boot.
I read somewhere that it's advisable to charge the phone when it reaches below 20% and continuously till 100% (without disconnection). Each disconnection means a new cycle of the battery which degrades the life.

@sukhjit, Did the same... No difference
I checked the battery information while charging. Jumps to 4228mv then charges slowly. If I disconnect the charger and reconnect then the voltage drops to a value, and again jumps to 4220mv after a 2-3pc rise in battery charge.. then charges slowly taking about 5 hrs for full charge. What should I do??

You could try replacing the battery! If this doesn't help most probably the battery is at fault. If any friend or family has a htc phone with same battery, you can ask for a one day exchange and find out if it's the battery or phone.

Also Are you using original htc charger? Charging from PC takes a lot longer as PC supplies less voltage to the phone.

[Q] Battery drop after reboot?

I've been experiencing huge battery drops (from 10% up to 20%) after I reboot my phone. Is this a KitKat issue or is it my battery?
In the morning from 99% (after checking a few messages in the morning), I rebooted and I dropped 11% to 88%.
I think It may have been my battery giving me the huge drops. I don't seem to have this issue any more after buying a new one. :good:
I didnt found it on reboots, but i have this problem when i enter recovery. 20 minutes in recovery - i dont hace 20% of battery.

Hmmm that's strange.
I've noticed it usually drops more when I leave my headphones in.
full loaded ACE 2.
reboot cost u 5%
first 10 % gone in a few minutes for heavy users and in a few hours when deepsleep !!
what i wanna say.
the first 10 % gone in a few.
after that normal drain.
I often get this, although not as bad. I usually lose 2-5% on a reboot, sometimes up to 10%. The other week I charged it to 100% when it was off, turned it on and had 92%.
so is this actually a problem or is it normal for everyone?. Mine looses 5-8% in the first couple of minutes after I unplug the charger..
It's normal.

Its normal. I usually lose the first 5% of a full charge in a couple of minutes. After it gets to 95%, battery charge will drain normally depending on usage.

ok then, thanks...I just thought that this didn;t happen when I was on GB, but it doesn;t matter anyway..
If I reboot once, I will lose between 5 - 10% battery. However, if I reboot straight after the first reboot, I will lose between 0 - 2% battery. I've never really understood this.

Phone need more energy for reboot, that causing the drain. Mine usually drop 2-5%. After recharge battery alsi drop to 95-92% fast. Thats normal

Battery Charging Issue
Is this normal?
When I charge my battery whether it be from mains or USB computer it charges ok, but as soon as it gets to 100% it still says charging for a little time and doesn't report the unplug charger message right away.
With the Jellybean 4.1.2 system I don't get the alert tone when the battery reaches FULL, therefore I have a feeling that when it still says charging even though it's showing 100% that it's actually decreasing power at that point, any help please?
I have tried other batteries, and one in particular goes from 90% right up to 100% and seems to miss that last 10 percent, so I don't use that one now.
I have the most current firmware installed.
Buy a new one

when it says 100%, you still have to wait for a few minutes before it displays the green "full" icon in the upper left corner and asks you to disconnect the charger.
However, the first 5-8% always drains REALLY fast and not proportionally to the rest of the battery drain...
I think It may have been my battery giving me the huge drops. I don't seem to have this issue any more after buying a new one.

what about the initial drain? does the first 10% still drop fast or has this changed too with the new battery?
I just wish that JellyBean 4.1.2 would give an alert sound when the battery has reached it's full limit like Gingerbread used to do.
Who would be the best place to ask them to do this on their next update?
But I think that it does..a very short one indeed, but it does, along with the screen lighting up briefly..

Doesn't make a sound on my phone and im not always looking at my phone to see it light up.
I have sounds all turned on and on full volume so no reason why I dont hear a sound when its reached full capacity.

Phone charging >> on/off?

hi.. should i turn off my phone when i charge it?
because when i turn off my phone and charge it, it stuck at 97%, it won't go fully 100%.
but when i turn on my phone and charge it, it can fully charge 100%..
does it mean my battery start to get bad?
and with this litium battery is it true that if we use it until it completely depleted the battery will go bad?
i know that every energy storage (like battery) has lifespan, what i wanna say is, if we use the phone till the phone drop dead (battery completely depleted will shorten it lifespan?
thanks
and i bought this phone bout a month ago

Happened at my stolen device also just like you said, but not experiencing with my present device redmi 1s (bought used device from someone).
My stolen device use stock miui 5 rom, i remembered install repair battery life app from playstore.
And somehow it worked, dunno if it caused by the app or not, you can try tho...

Yes, like i said, "just like you said" about the device,
And im currently at cm 12.1 r4 and since the first cm 12, its the opposite
You'll not have issue with stuck at 97% charging while power off, but you'll stuck at 3% while using phone (no charging), never reach 0%.

No its not going bad. Its normal for the charging to slow down alot at 97% since overcharging is bad too. Just unplug and use it once its >95%
And yes its very bad for lithium batteries to go completely flat, and their lifespan will be longer if you charge it more often - that is a shallower discharge depth is better.

How I fixed my battery life [Calibration][NoRoot]

So I am on the WWE of Nougat, version 2.41.401.41. I was getting abysmal battery life, at about 2h30m screen on time, without doing anything special (just browsing, some social media, etc.).
Also, AccuBattery was showing the battery capacity at 2300 MhA, which I found quite impossible for a one year old device.
I suspected that my battery was badly calibrated. What I did is what is described in this thread, slightly modified:
Charge the phone while turned on up to 100%.
Remove the charger and reboot the phone. Upon reboot, the battery will have dropped at about 96-98%.
Reconnect the charger and charge again up to 100%.
Remove the charger again and reboot the phone. This time, the battery will have dropped again, but not as much as the first time.
Repeat steps 2 and 3 until after reboot your battery remains at 100% or at least 99% (depends on how freaky you want to get).
After doing the above I have been getting about 3h30m to 4h00m screen on time and AccuBattery is showing about 2700 MhA battery capacity.
Seems that HTC has really messed up the battery calibration on the 10. Hope this little "trick" helps you as much as it did help me.
----------------------
A follow up to this, here is a reply I got from HTC support, regarding battery:
* For battery calibration :
please unplug the phone from charger - turn off the phone device - press on Volume up + Volume down - Power on button all at the same time till the phone started on , please check the battery indicator ,then follow as below :
1. Restart your device
2. Turn on Airplane Mode
3. Connect your device to the charger, and charge it fully
4. Set screen brightness to Max.
5. Set Screen Time out to never.
6. Dial *#*#3424#*#*, choose battery and Charging run down test, and follow the instructions.
If the device loses more than 40% of battery in an hour, then send your device to the repair center

Depends on the usage really. I have given up on measuring the SOT, I just plug in every day at night. But has been pretty stable, gets me through the day.

Fair enough, it's a bit pointless at this point to be honest. Does the phone reboot randomly below 50/60% or has calibration fixed that issue? That's the biggest gripe I have with the Nougat update at the moment. If calibration fixes it, I'm gonna do it now! If not, do you reckon another kernel fix it?
Thanks for replying!

Turns out it is a common issue:
https://forum.xda-developers.com/htc-10/help/random-shut-boot-loops-t3690547. Seems to be software related hence my initial question!

Did that work for you?
For me the htc tool is showing like 6-7%discharge over the one hour...
But if I I use Spotify or any other online/local music app, this can't be true...
Seems to be a software problem, nothing to do with nougat or oreo, nor with firmware version.
Trying the "manual" calibration tomorrow.
About the 40% rule... I already had a support guy say it only needs to be 25%...
Still my battery is far far away from that... Sadly, would love to send it in to have a fresh battery...

from my understanding you are referring to the 40% in the quoted text
so when you do the test it should only lose about 25% in one hr like the HTC rep said to you instead of the 40 quoted by the other forum user?

Right, I am in contact with the HTC support using their FB chat.
Last time I asked, still on HTC One m7, it was around 40% for me too.
This time they said it should not drop below 75%.
To be sure you should ask the support yourself, maybe it depends on the country as well?

Have you tried wiping the cache partition, my battery was 100% & went to 81% and held its charge for much longer, it's a short way of clearing your battery stats
Another trick
I found an alternate trick and it looks like it's a bit more effective (at least for me):
Basically following OP's instructions: charging it to 100% then turn the phone off. But instead of restarting, Turn OFF the phone then hold power+volume down until the backlight of the back and app switcher buttons flashes twice then let go. Then turn on the phone while holding volume up. I think this helps force a battery recalibration every time.
When I did it once I got to 78% then the second restart 55%. I'm currently charging for the 3rd restart to see if I can get better than that. Previously when I tried OP's method a few days earlier I got 78% on the first restart , 98% on the second, and 99% for every time I tried after that.

Did you unplug the phone before turning it off or did you keep it plugged in?
have you guys tried the Chargie app? It's coupled with a hardware device that limits charging to the phone at your desired level and saves the battery long term.
Unfortunately none of the above did the trick for me. Still, the phone randomly (once in a while) goes to loop when 15 to 20 percent of charge is remaining and won't stop before I plug in a charger. /sad face/

Well the test consumed around 50% of my battery. The issue that started around a month ago is that my phone shuts off around 30% battery , however it won't switch on again till I plug-in the charger and when it is on , the battery is at 1%. Seems that the phones is displaying a 1% as 30% before shutting down. What should I do ?
