Oneplus One Battery discharge even when completely switched off

From past 1 month I'm having a hard time with my 1+1, I started experience heavy battery drain during stand by around 35-45% over night (aprox7-8hrs) I thought the battery has come to end of its life so I ordered a new battery for 1+1 and replaced it myself. But guess what I'm still facing the same issue overnight the battery drains 35-45% even when the phone is completely turned off. What's happening I don't really understand. I also tried charging the battery to 100% and removed it from 1+1 and left it for a day and when I popped it back in it was holding the battery very well it was 99%. It is only draining when I connect it to the phone the battery starts draining again. Is there anybody who can help me with this issue.? I really like this phone that I don't want to buy any other phone right now.

Ya but I cant I purchased it last year around June even before it was launched in my Country. So have to try to fix it myself

Hey hello..
I pity you.. Btw even I have similar problem.. I know how it feels.. The battery used to last 2 days easily and now merely pulls a day.. Same 35% battery drop even when I have it switched off.. I have tried almost all ROM's in vain.. Only thing I can tel you is, try charging the phone overnight and discharge completely before charging it again.. repeat this for 3 to 4 times.. This trick worked out of nowhere for me.. But again now after 10 days, it has gone to the state of not holding juice longer.. I am at a loss to understand what is wrong..
PS.. Do lemme know if you find a way out of this..

galaxy j7 battery problem

i think my phone has some serious problems and i'm wondering if it's the battery dying or a short circuit
when i plug it on a charger while of it shows a normal charging image but how it switches from one animation to the other so i can see the status of battery percent it's like a short on the screen happened
it chargers to 100 but when i switch it on it shows mybe 95 but never 100 and if i connect it to a charger to get to 100 it only decreases
it gets warm now days which did not happen and it like drains 50% overnight which is obviously not normal. these two days the battery life is like 4 hours with internet wich with j7's battery it should not happen. if i switch it off and then on again i loose like 20% of battery and if that is all i had i get 0% and the phone doesnt switch on. the phone never had contact with water . it's been 4 days since this started and it happened all of sudden like today my phone stays up to two days at most and i just woke up it barely finishes a day without data and with power saving mode
i'm sure it's not about background apps or any activities because i hard reset it already and i don't have any app. and it's not about wifi or sync or poor network i tried all that. i did everything it didnt help. i could buy a new battery but i'm scared it might be a short because i don't think a battery can just die in one night like this.
can anyone help me with this or it's nothing serious and i have to change the battery

Charging Problem

It has been just 20 days, and I have just realised that there is a charging problem with my Honor View 10.
At night, when I turn off my phone and put on charge, the phone starts charging but in the morning i. e arnd after 7 hours I see that the battery is around 70% and still its shows that its charging but actually the battery is draining because after sometime when I check it again the battery is like 68% or so and it still shows charging P. S in whole process the phone is switched off and this happens every time (around 6 to 7 times). And I am using the same charger that came with the phone. Phone is updated to the latest firmware.
I have done the factory reset but still the same problem persists.
Please you guys check and let me know if anyone else is also suffering with same issue.

Better you should visit company service center or probably honor official forum for support from company... As far as I think it is your handset problem either check with ampere app from play store to see how much current it is taken when charging , so either your charging port is damaged , maybe charging IC or maybe battery issue... Not sure though..

There is charging related bug in the latest update. Also battery drain is higher. You will need to wait for next update.

Lets wait and watch!

Apr 2018.. Same charging issue. Shows fast charging but doesn't
This post is from Feb and I bought this phone now in Apr. I am facing the same issue. The fast charging lasted for a day and then it is very slow.. Max 750mah measured via Ampere app. Earlier it used to be excess of 2500mah when it was fast charging.
Have you find any solution to this issue?

Google pixel 1 (5") depletes as it charges.

Basically my Google pixel has been having these issues since January/Feb
But the phone refused to fully charge it would stop at 98% and the battery wouldn't last long at all I used to get 4h screen on time and have like 20% left now I get 2h 22m with the replacement device that Google gave me.
I have had the device replaced four times, yes four. And I have tried to charge the device with no data on it and no email. So it would be a fair test.
With this, the fourth device, it charges, then reaches 100% then depletes while in the charger and not being used and so it has 97% after.
The device lasts no where near as long as it should and when I take it out of the charger in the morning it drops from 97% to 92% with 5 mins of use.
Google are now telling to replace it again. I am using the official charger.
Someone please advise me!

This is happening to my Pixel too. Also when battery has like 25% left, the phone suddenly power off, and it won't turn on until i charge it. When it boots, the battery indicator shows 1%. Truly weird. Idk if it's a software issue, a battery issue or wth is it. Hope somebody has a solution

Both of these sound like bad batteries.
@Zikohh, you're probably being given refurbished phones as replacements, and they don't have a new battery. I recommend you suggest them to pay for a battery replacement, rather than change the device again.

hopefully they will agree. Four replacements had the same behaviour. And yes they are all refurbs.

Two things try to update (may security update) and if not any better and you haven't already - try a factory reset my camera app caused similar stuff and a factory reset fixed it. But if you tried once don't bother just try updating it.

Poco f2 pro charge only to 89%

Hello guys,i bought poco f2 pro global a week ago.My problem is the follow:
When i put my phone for charging the process go to 89% and freeze there.if i disconnect and connect again the charger then its make it 100%!?u can wait 5 h but no more than 89%.
Its very anoyning ,coz when i got to bed i put the phone on charge and at the morning i get it on 89%.
Factory reset didn't solve it.Any ideas?thx

Try draining the battery to 0%, then let it charge uninterrupted and see if that helps..

Hi if you've seen some of my posts. I got a Poco F2 Pro and on the second day it started showing 1% battery charge all the time. As well as an overheating issue and would close the camera after 5 seconds. Not sure what I did other than turned it off and let it charge a few times. For no known reason it started working fine. That was a week ago, so haven't had the problem occur since.
I'd check while the phone is off what the battery level shows as. If it still shows 89% it might be more serious, otherwise could be a bug

ITs not uncommon a miss-calibrated battery. Make a full discharge, wait all the time until your phone is power off. Once completely drained, try (without charger) power on some times, to be completely sure is totally death. Now, make a complete Full cicle. This time, the phone should reach 100%

Thank you all for the suggestions. I discharged the battery to 0 %,then plug it again and the result was 92%.So no luck..I really hope that this is software bug and will be fixed with miui 12 .Will be very unlucky if my unit is defective.the phone is a week old .what do you think,if i download the present software and flash it , maybe that's will help?

This so called "calibration of the battery" is total BS.
At every boot with at least the latest 4 Android versions it will "calibrate" itself and nothing one can do about it to "trigger calibration" or that kind of stuff.
When the battery won't charge beyond 89% something else is causing it, faulty battery or software related.
Did you unlock your device or is it still locked?
When locked try to manually download the whole rom new from the update menu and reflash it.
Then check if it charges correct of not.

Some devices that I have seen with the same behavior would not think the same as you, obviously with a healthy battery. A bad battery can behave abnormally too, but I doubt that is the case.
And yes, it can be called a ... "calibration", although nothing to do with the supposed magic cures of deleting the battery statistics file. What happens is not that % battery is lost or that the battery is not fully charged. In fact, if the battery is fully charged, it is the count that fails. This is perfectly evident, when the phone reaches 1% it stays in that% much longer than usual, because the phone really did not have 78% (for example) and is not full drained yet. Once the battery is completely drained, the margins are recalculated correctly again. It is not a bad battery that is not fully charged, it is fully charged, what happens is that the battery reports incorrect data due to a "calibration" mismatch.
In any case, the partner will be able to tell us perfectly if it worked, or not . I repeat, there are many phones that I have seen with this behavior and many that have returned to their being. It is clear that if the battery is bad it will continue to be bad. It has happened to me in the past with a pair of Xiaomi phones, the last one a Redmi 6, is not uncommon

Hi
Sorry , i don't have anything intelligent to say about battery calibration (except that if the battery sound faulty, take advantage of the phone warranty while you can!)
So... I just saw @Snah001 had a F2 pro and a Mi 9T pro... Could you please give us your quick opinion and advice here ? https://forum.xda-developers.com/poco-f2-pro/help/poco-f2-pro-t4137287
Thanks so much
Cheers !
