My Xiaomi Redmi Note 7 discharges while plugged in - Xiaomi Redmi Note 7 Questions & Answers

Recently, my redmi note 7 phone started to take a long time to charge. It's been several days since I was able to get it to 100%. It got worse as sometimes, the battery drops while charging. I can't tell if it's a software or hardware issue. I updated to the latest, MIUI 11.0.1 before going online to find that many experienced charging issues after updating. But for me, this issue has existed before I updated the phone. Anything I can do to fix this?

Maybe dust in the USB port, other cable or the charger.

I've cleaned the port with methylated spirit. No difference. I haven't tried another cable yet though, I'm the only one in my house with a USB type C charger.

[Q] Nexus 7 does not charge while on.

My Nexus 7 is no longer charging while turned on. If I power it off it'll charge with the battery symbol. I can't even get my PC to recognize it while plugged in to USB. I'm using the stock charger and cable. Any thoughts?
I'm currently running Paranoid Android 2.54, however when this started I was on 2.50. I thought flashing a newer version might help.
Not charging
Plus 1 on this issue,
Running stock ROM and it updated yesterday to version JOP40C now it's only charging when turned off.
+1, same here, but now it won't charge as the battery got completly drained.
Still does not charge. This is a launch N7, curious if Google will replace it.

I just received a replacement seven this week for the same issue, mine stopped charging. I called google play customer service, and they didn't give me a hastle at all.
Were you rooted/running a custom ROM? I am, and with my N7 not getting recognized I feel like flashing back to stock might be problematic.

yea, rooted, custom ROM and kernel. doesn't matter though, it just started one day randomly. I finally did get it to charge BTW, by giving it a few firm smacks on the back. they didn't even ask if it was with root or if it was a custom ROM. if its hardware related, it won't make a difference. i sent it back with twrp recovery, rasbean jelly rom, and trinity kernel. i did wipe the data and the storage before i sent it in.
Yeah my Nexus' charging is messed up since 4.2. Battery seems to run down extremely quickly (around 30% in two hours with Spotify on and general browsing.) Plugging it into the wall with the official charger sometimes charges it EXTREMELY slowly, and sometimes just says its charges and still the battery is running down.
It happened to charge last night, and over the course of around 10 hours, I think I had 60% battery. Trying to charge now, and nothing, just losing battery. No idea what the issue could be. Tablet completely stock.

+1 on this issue. N7 isn't charging when turned on, no charging issues if turned off. It isn't recognized when connected to a PC. Whenever I try switching users, the darn thing restarts itself. It does the same thing when I try USB debugging. I am running 4.2.1.
Please help!
Investigated problem
After upgrading to 4.2.1 my N7 charged very slowly. Finally today I decided to investigate it, albeit inaccurately.
Plugging a 2A charger into my 120V power monitor, I noticed the following:
When the N7 was on, the power draw continually alternated between 0 watts and 2 watts.
When the N7 had been shut down from the bootloader (not from the OS) and the cable plugged in/out, the power draw was a constant 2 watts.
The max charging rate of the N7 is around 10 watts.
So it looks like the N7 is will charge either very slowly, or kind of slowly. What I find strange is that this issue only occurs on some devices. Perhaps later devices use a different charging controller?
Either way, would really like a fix for this.

From the way you described your test setup, you seem to be measuring the power consumed by the charger itself on a 120 VAC source. The wattage there should be low, albeit still higher than what you're seeing. Along that line, if you ever see it go up anywhere near 10 watts, then something has gone horribly wrong.
Also, the slow charging seems to be peculiar to 4.2 and above, indicating that it is not actually a hardware issue.
same!
Been having the same problem for a few days now, I was on stock 4.2 and updated today to a custom ROM based off of 4.2.1 and there is still no difference. Anyone found a solution yet?? Its quite concerning especially since I got mine from GameStop in the US then moved to the UK shortly after!
Just wanted to add, before this started I was having the same problem that is talked about here http://forums.androidcentral.com/google-nexus-7-tablet-forum/228706-nexus-7-problem-wont-charge-when-does-screen-goes-dead-pixels-fly-across-screen.html
I figured it was caused by letting the battery drain completely so I opened it up pulled the battery plug out, plugged it back in and charged it till it was full and it continued to work. haven't let it die since.
Same problem here, stock Nexus 7 running 4.2.1, roughly 2 months old.
It charges when the device is turned off, but will not charge when powered on -- started happening about 2 weeks ago (charged fine previously). This is using the stock brick and cable that came with the tablet.
I have to imagine that this is a software issue and that the next one will have a similar problem -- has anyone else swapped one out and had the problem disappear with the new one?

[Q] Nexus 7 will not charge

my nexus7 will not charge until it has completely drained....
I am aware of the current battery problems, but mine is a bit different....
Even after going to bootloader and choosing power off my nexus will sit on charge (wall) overnight and be dead in the morning, even though it was at 30% when plugged in....
The only way to charge it seems to be off my laptop. but even then it takes over a full day to charge.
If i hook up to laptop while runing it basically only slows down the drain but still doesn't charge up....
this is very frustrating, and i'm at my ropes end
would dowgrading to an older rom take care of this issue?

No solution, I'm afraid, I'm chiming in to say that I have also been having problems since the same time. For two days, I have been trying different combos of chargers, cables, and outlets, to see if other equipment is the problem. But all of it works fine with my Nexus 4. Mostly, I am experiencing that the unit says "charging" but the battery level is going down instead of up. I managed to get a full charge overnight by using an external battery that I got just for this type of emergency backup. After use, it is back down. This morning, third cable I tried finally seems to be working, for now. In 40 minutes it went from 63% to 65%. I am somewhat relieved but this situation is not normal.
I'm going to start reading through the forum to try some suggestions. I wasn't paying attention to updates. Has this problem been triggered by a recent update?
I understand some suggestions call for letting the battery discharge entirely. It seems that won't be hard to do. I can leave it plugged in and, as happened with most of the cables I tried, the battery level will go down to zero pretty fast. I'm really annoyed, but very happy right now that I splurged on an external battery.
Have you tried a new charging block... That would more that likely be your culprit.

Check your port for bent pins.

I used three different chargers plus the external battery. Two of the chargers have two inputs (i.e., for Apple and non-Apple products). I have five different charging cords, longest is 6 ft and the others much shorter (two are from Monoprice), and one retractable I usually use in the car. I tried every combination I could think of between chargers, cables, input ports, and several different electrical outlets at two locations.
All the various combos functioned fine with my Nexus 4, the other device I have with me. None of them worked with the Nexus 7. All showed as "charging", but they weren't. In some cases, the numbers were going down quote rapidly. Goes without saying, when you're charging, it shouldn't go from 64% to 59%.
The thing that finally worked - with no hiccups - was the external battery. Since everything worked on the Nexus 4, it's quite apparent the problem is the Nexus 7.
Having said that, by this morning, things inexplicably changed for the better. With the device at around 70%, I connected one of the chargers and it functioned normally. Battery filled up within the normal timeframe. I was using it intermittently while charging, as I often do.
I'm glad it's working and very glad I have the external battery that can fill up both the Nexus 4 and Nexus 7 in a pinch. But I still think there's something wrong with the Nexus 7, and I'm not knowledgeable enough to dare try some of the more technical suggestions. Just the term "shorting out the pins" is enough to warn me that I'm not expert enugh to try anything like that. For now it works, I hope it lasts like that until perhaps I can understand the issues a little better.
I'm having the exact same issue as you guys and it has me stumped. On some days it'll work, others it wouldn't. At first I thought I could fix it by rebooting but last night mine just drained all the way down overnight while charging from around 50% and this morning I wasn't having much luck getting it charged using the 2 stock Nexus 7 wall chargers that I have. I'll try using an external that I got recently and hopefully that'll solve the issue for now at least.
Edit: Some people have had luck reversing the polarity on their charging block. I'll give that a go and report back whether it worked for me or not.
Edit/Update: Yup, flipped my brick around so that the big end sticks off the left side and it's at 32% now from 0% after 2.5 hours. You guys might have some luck with this too.
Nexus 7 fails to charge
We have two Nexus 7 in the house, one 11 months the other 6 months old.* The older one stopped charging just before our holiday last month so we took the other. It stopped charging while we were away.* Fortunately my wife had here Samsung Ace [mains] phone charger with her. This worked every time.*
Once home I checked the two Nexus 7 mains units and 2 Nexus 7 usb cables. No combination would charge either Nexus 7.* The Samsung mains charger would always charge both Nexus 7.
Solution:* Suspicious, I ordered an Asus Nexus 7 cradle while we were away. Any combination of Nexus 7 mains unit and usb cable charges both Nexus 7s on the cradle.
Conclusion: The USB socket on the Nexus 7 cannot take repeated insertion and removal of the cable.
Hope this may help somebody.
Yea I had the EXACT same story as you. I had for got to take my nexus 7 charger on holiday but I had my Samsung galaxy ace (s5830i) charger so I used that. when I came back and pluged In my charger It said that It wasn't charging so I used my brothers nexus 7 charger but still no good. It said that my brothers nexus 7 was charging but not mine and than I figured out what I had damaged... My nexus 7 charging port. I had proved this by comparing the the 2 charges and they where very different... Luckly It was still under warranty so I took it to (I cant tell you that). I looked all innocent and pretended I was new to this stuff and they then tried to charge it but no use so they replaced it with a new one but now I know not to put different chargers in my new nexus 7 and that goes to people out there as well

Battery/Charging Issue

Hi everyone,
Thought i needed to come to the expert on this one as i've not seen much online, but i have seen a little on here.
I'm having severe charging/battery issues on my Nexus 6p. The phone is about 18-20 months old now (purchased in nov 2015).
So I'm on the beta program so i have Android O developer preview 4 installed currently. Over the last few months ive found that my battery has been depleting rather quickly, which is not too much of a bother as i have chargers scattered around the place, either that are Benson approved or it's OEM. This last week ive been trying to charge my phone and after leaving it on charge all night i woke up with it at 90%. Then when in bed i placed it on charge and was using it before i went to sleep and i found that it was discharging (all with the OEM charger). Now it is taking an absolute age to charge so I'm trying to figure out what the problem is.
1. The battery has reached full cycle and now i need to replace it (i've ordered a replacement battery but dont feel comfortable installing it myself).
2. The charging port is messed up?
3. I need to roll back from Android O?
Please let me know what your thoughts are and if you need any other info let me know.
I appreciate the help.
Thanks
My Nexus 6P is also on the Beta Program - Android O.
The problem I am having is that my phone is no longer rapid charging ... it just says charging.
My brother also has a Nexus 6P and I used his charger and cable that is rapid charging his phone and it is still not rapid charging mine.
Does anyone else have this same problem or know of a fix for this problem?
I'm also on DP4 Android O. I had this problem when I installed every DP. I got a tip around the net. And it worked for the drainage problem don't know about charging problem. Make battery to dry. Make sure your phone doesn't still have any juice left. And Try to startup your phone for a five to ten times without being plugged. And now plugin the charger and wait till it reaches full. This may may or may not work but you can see decent battery life than the previous usage. Worked for me

Op5 won't charge past 70%

The past couple months I have had some charging issues with my phone. The first few times it just didn't want to recognize the charger or would only slow charge. A couple times cleaning the port helped. Then it seemed like the cord might be the problem so I ordered a new OEM one. The problem has gotten worse and happens the same with the brand new charger.
The last few days it will fast charge to 70% and then stop charging altogether. I can't get it to take any more than 70%. I had the accubattery app which had a feature to stop the charging at a preset value to prevent wear of the battery. I only used this for a little bit and turned it off. Then I uninstalled the app in case a glitch was causing it to keep stopping the charge.
I have a new OEM battery ready to install if the battery is indeed faulty but even starting at 70% I can't kill the phone in a day so I'm not rushing to replace the battery yet. I'm just not sure that is the problem.
The phone is not rooted and is completely stock. It hasn't been wiped or anything since I bought it new over a year ago. Anyone have any ideas?

Update: I powered off the phone when it was refusing to charge at all and it was down to 56 percent. While powered off it charged all the way up to 100% no problem and since doing that it will charge without problems. Seems like this fixed it.
Update: the problem is still there. Still not charging above 70% while turned on. Not sure if the battery is failing or if it's a software issue.
Does anyone know of any other forums people might be discussing issues with the OnePlus 5? This forum is looking quiet these days and/or people aren't having a lot of hardware issues with this phone (hopefully).

The op5 forum isn't quiet. If nobody has an idea or any possible solution for you, you won't receive an answer. Seems you're the only one who has this sort of problem.
If you have warranty, just claim it. That's the easier way. Cause when it's the logic board or parts of it, it can be expensive.
It's already over a year old so no more warranty. I'm just going to try replacing the battery when I get a chance. If that doesn't work I'll try a new charging port (already tried a new charger).

Have you tried using the Ampere app? It does not make any magic, but it can give you and idea of what the problem may be.

Yes I installed it the other day and discovered when I was plugged in above 70% it was actually charging but very slowly. But this isn't always the case because when I first discovered the problem I kept waking up with a phone at 70% that had been plugged in all night.
I'm not sure how long ago this started because I typically try to charge it in the morning after my alarm goes off since dash charging is so fast. Eventually I noticed it never getting above 70% so I plugged it in overnight and still didn't get over 70%.
Accubattery says my battery is now 82% healthy. Despite not being able to charge above 70 I can still get a heavy days usage or a couple easy days. So maybe the lost health in my battery came completely off the top of the displayed percentage of my battery?
Occasionally it seemed like my phone wouldn't charge at all no matter what the percentage so the problem could be worse, but I may also be dealing with a worn out 1 year old charger cable and a new one I got a month ago that is defective because when I couldn't charge at all with the new one the old one charged fine. So I'm still trying to figure this out.

i am facing the same issue, i keep plugging the charger in and out till it works ... don't know why
Now that I've gone back to the original charger it seems to be making it to 100% every time and no longer seems to stop at 70 but if I move the phone a little while plugged in it sometimes stops dash charging and starts slow charging. Before when I heard it stop charging and start charging again randomly while I was in bed (it makes that little sound when dash charging starts) it was sitting on the floor unmoved.
So I think my possibilities are 1) 2 bad chargers
2) 1 bad charger and a bad charging port
3) bad charging port
4) bad battery + 1 or more bad chargers.
Or any other combinations of those problems. I think I'm dealing with 2 issues and that's why I can't figure it out.

Question Anyone facing battery charging and drain issues?

Hi, I got a Nothing Phone (1) around 20 days back. Ever since the Phone has received only one system update that too was just a couple of days ago. I thought the battery drainage was something that happened from the beginning. A couple of days back, the phone wasn't charging. I was using a third-party adapter, One Plus Warp Charger for One Plus 7T my previous phone. Anyone facing battery issues with third-party charging. I am getting myself the Nothing Adapter for sure. I just hop I am not too late. I love the experience but battery life and charging issues are something I don't want to deal with again!!
I'm have been using third party 35w charger since I got my Nothing. Working perfectly fine, charging fast, battery working fine as usual. Nothing Adapter kinda pricy to me so....

Better invest in a proper charging adapter because the one you're using rn have different technical specs comparing to the Nothing phone adapter
