Battery gets hot, won't hold charge - Xiaomi Redmi 4X Questions & Answers

My Redmi 4X has developed a battery issue. The phone gets quite hot, and the battery won't hold a charge for more than a couple of hours. I can watch the charge level go down. Is this fixable?

Are you using custom rom or custom rom with custom kernel? This may give such issue.
You should give more information about ROM, custom kernel (if you are using), are you using original accessories for charging?

I have no idea what you're talking about. I just want my phone to work, I don't care how it works. I am using the charger that came with the phone, but this issue started around a year after I got the phone.

Okay, in simple words I was asking if you are using any third party/after market software (for e.g. Lineage OS).
Redmi 4X software is MIUI.
For your information some bad seller install their modified version of software and repack and sell it(not to worry it can be changed to original) which ruins whole experience of using device and users don't get any updates and get stuck with fake software which may cause issue and that was the whole purpose of asking ROM(which is your software on your device which can be checked in settings> about phone)
Most possibly software update(s) may cause this issue or faulty battery.
Redmi 4X has 4100 mAh Lithum polymer battery which usually should last up to 2 to 3 years or more with some battery capacity decreased considering xiaomi gives good batteries in their devices.
Even with several recharge and discharge it should retain it's 80% or more of capacity over years of use.
There could be issue with battery or software causing this issue.
If you know how to install/flash software then I would recommend you to install latest stable version of MIUI (software) to check if software causing it or not.
If it doesn't then it is probably issue with battery and it may need to change.
If you are totally don't know anything at all about above my mentioned things it's better to visit and get checked your device at official xiaomi service center.

[Q] Battery problems G1

Hi to everyone! I have a g1 and I decided to use it again. I replaced the battery for a new one (I bought it few days ago). When I used after charging it all night it just lasted 3 hours. Then I googled for solutions and I did all what I found (charge it full and reset battery stats and let it drain all, charge it with the phone off, etc) without results. Then I tried one Barry with more capacity (the ones that you need to change the cover) that a friend have and was the same. After more or less three hours, the phone turned off. I had cyanogenmod 7 installed with the latest radio and spl. Today I tried with stock room, unrooted with the same results.
If someone knows a solution, please let me know. Thanks
It may be your ROM, but this is very new to me, even those big ones? Try another ROM:FroyoByLazslo is my favourite and fastest
I'm checking with the stock rom, but I'm going to give a try. Thanks!
Hi,
maybe you overclocked it very much; this can use very much battery. If you want to save energy, you should undervolt it...

Hmmm, I don't think is that. I tried with the stock room (1.6) and was the same. And this morning I tried to use the phone, but I had decided last night to turn it off to save battery and was dead! Maybe the phone has something... today I flashed the room froyo by laslo, looks good and is fast! I'm going to underclock it and see what happen. Also I read something about a draining problem when you connect it in the laptop through usb, might it is the cause of all this?
Only with some kernels, if your drain problem is due to software then flash a different kernel

Yeah, may didn't wipe during a ROM change?
PS: You're welcome!
HI, after checking all that you say. I wipe all and after I charged the battery, y wip e the stats and now is working better! With the normal one, I get 6 hours on standby and with normal use, 4..... I tried with 2200mhA and I get 12 hours with medium use, but I with this one the phone is bulky..... BUt well now is my gps!
Thanks!
No prob dude we are here to help the guys who need help, that's why it's a forum XD
TC, you must understand that all G1 batteries are quite old now. They were made betwixt 2008-2010, batteries begin losing their max charge right after they are made in the factories. It's only natural for your battery life to be poor, batteries can be damaged heavily by heat sources, my notebook's battery life became 5 Minutes b/c the wear level was extremely high. I assume your G1's battery is in "bad" condition cell wise. Either calibrate or buy an OEM battery(3rd batteries are tricky). If you calibrate try one of these...

Also if you need battery you should honestly stick with cupcake, donut. Anything past that is already sluggish and pushes the G1, which means the CPU is always at max which leads to shorter battery. And lets not forget the post donut versions have more services and what not.

What's wrong with 3rd party batteries? In my experience I've had two different ones bought off eBay and each worked better than my new OEM battery.

Battery issues already?

I'm not sure if this is hardware related but as of this morning my n6 will not charge beyond 93%
My phone is just over a month old and I'm running a fairly basic cm12 build.
Has anyone else experienced similar issues?
Ok have you gone back to stock just to make sure it isn't rom related?
Install "ampere" from Play. Its the only truly accurate battery / charging monitor I've found.
Essentially the android OS works out what the percentage is based on voltage information supplied by your battery chip. Charge your phone as high as it will go, take it off charge and see what voltage it reads. Compare that voltage to someone else with the app installed when they are at 100%

Almost. Android doesn't have the voltage-percentage table. That is PMIC+firmware.

I believe it is a rom related problem, i have had my n6 for over a month and just last week decided to root, while on stock my battery life was REALLY GREAT and once i installed CM12 I've been having all kinds of issues
it's an early stage of cm12, it'll get better but for now i think i am going back to stock

Seriuos Overheating and Battery Problem??

Hi everyone! My phone is 2 months old, 1 week ago, my phone start to heat so badly, in upper part is really really hot... As a matter of fact the battery is drained really fast, 3 hours in stand by... Before can get one day easily... Make a factory reset, doesn't work... The problem start a few days after I update de stage fright update, you think is the problem? Anyone else experience this? The phone is out of warranty in USA, cause is a UK version, xt1068....
Ty:good::good::good:
processor in probably running at full speed doing something it's not supposed to. I seriously doubt it's a hardware problem so I would recommend unlocking the bootloader and try using another ROM.
could it be as a UK phone in USA its always trying to find a better network? this would cause heat and drain issues?
Yeah think the same. I'll try... The 5.1 update it suppose to comes up this month...

I do not think so... Happens the same, without sim...
Besides, even when I charge power off, with a wall adapter 1A, it never charges, because it discharge more easily than charge. I have to charge with a 2A charger, but is really slow, more than 8 hours to get completly charge... What do you think?
As decipher said, what seems to be is a process eating all the battery and keeping the CPU at full speed. We don't know if it's an app you're using or an Android problem so to see it the best thing you can do is to unlock your bootloader, install twrp or cwm recovery and then flash a custom rom. Personally I had some overheating problems on my xt 1068 at stock version and battery drain, but not this 3 hours standby you're getting. Now I'm using Minimal OS and it's working nice! Tell us if it solves your problem! Good luck! :good::fingers-crossed:

Yeah, ok, so, when I charge it power off, it still keeping heat and draining the battery, so weird, right?

Yes. I don't like to say this, but maybe it's a battery issue. But let's listen what other people say.

Placing the 3400 mAh Oneplus 3T in the Oneplus 3

JerryRigEverything just placed the 3T battery inside the 3. And everything was working fine. Only the software part still only recognizes 3000 mAh. Is this something that a custom rom could fix? Or is this in a part of the OS that is closed source? It should charge to 100% anyways.
This could give the 3 even a longer battery life when the battery would die eventually.
https://www.youtube.com/watch?v=n1sg2y8OuJs
That is an interesting find. I really do hope this is something the kernel devs can add via an update from 3T sources. I have no remotely idea about kernel development, so can't be sure.
This does sound like a worthwhile tweak to keep in mind for when the battery on the oneplus 3 inevitably starts to wear out. How are the charge speeds? If the software is reporting it incorrectly, does it at least charge at full speed?
I had look into 3T kernel sources and Oneplus might did it trough very weird ways. For example, this file from OP3 is the exact same than this one in OP3T sources. The file is explicitely talking about 3Ah battery, whereas OP3T has a 3400mAh one. But some intresting changes occured in drivers/power/qpnp-fg.c file : OP3 vs OP3T
I dont have many knowledge in kernel source and editing, even if i got the LG G2 battery on my old Nexus 5, and even its correct size detected by kernel edits, it seems that Oneplus, and more modern phones dont deal with battery "drivers' the same as before
Sourcing the battery from the 3t may be difficult as well. Has OnePlus ever sold 'spare parts'?

There's a bunch of OP3 batteries on eBay. I would imagine OP3T batteries will start showing up also.
I'm just not sure if I would trust the eBay batteries. They may be fine but they may also be a crap shoot
Wouldn't it be very easy to port the 3T battery-related software to the 3? This would solve the software limitations, no?
Have we had a chance to test out side-by-side in regards to SoT/longevity of the 3+3Tbattery?
But if we put 3T battery to 3 is it still giving more juice's even when software dont recognize it?

Could this be due to some extra protection to prevent overcharging a battery?

Idk but batteries always have an IC preventing overcharging, etc, so I don't see the point for a phone to get kernel controlled switchoffs for charging batteries
Look at this video from JerryRigEverything, he got the same 'issue':
https://youtu.be/n1sg2y8OuJs?t=2m20s
How about the different termination voltage of the 2 batteries? How are handled? The size are the same because the more capacity is reached by a higher termination voltage rather than a different size. This make me think that they have different chemistries first and than the circuitry should also be able to manage different voltages and the different charging stages because they would happen at different voltages. Even if chemistries are the same charging the battery with a higher termination voltage treating it as it would be the standard op3 batt will lead in pretty much the same capacity fitted in. Imho... As this is what normally happens when you charge at 4.2V a battery with nominal voltage of 4.35V ... If you have confidence with 18650 batteries you know this stuff
OP3Ts battery gets charged to 4.314 volts and that's exactly the same as in OP3 so it'll charge fully in either phone. I'm guessing discharging is the same except OP3Ts battery holds charge for a bit longer. There's no need for software support, you can actually just swap them and get better battery life. If it's priced south of $30 I'm going for it as soon as it's available.
This would be fantastic!
Any news regarding this ?
most important thing is availability of original oem battery.
as far as I know OnePlus doesn't sale spare part.

exactly. I do not see any chance to get the new batteries... (except out of damaged oneplus 3T's)

hmmm interesting i have few questions now:
1. 4.314V is an OP3T battery in an Op3 NON-T phone?
2. Source for 4.314V?
Because if you see the video in here
https://forums.oneplus.net/threads/oneplus-3-oneplus-3t-battery-swap-works.476918/
The OP clearly states different voltages and you can also see in the attached screenshot 4.35 VS 4.40, which corresponds obviously in a difference in capacity
Also if the 4.314V for the OP3T battery is reached in an OP3, then this would be pretty understandable. If the circuitry of the OP3 can be firmware coded to a different voltage this is a thing i could not know at this time.
1. that's op3t battery in op3t
2. http://forum.xda-developers.com/oneplus-3t/how-to/battery-life-sd821-400mah-t3505786/post69936814
What's funny is that according to the same thread mentioned @ no. 2 op3ts battery discharges to 3.39V which is quite a bit lower compared to op3s battery 3.54V.

Question Does anyone know why my Redmi Note 10 5G do this?

It randomly died at 50% charge, then when I tried to boot it up all it shows is a black screen with a white empty battery icon, what does this mean? And how to fix this? Please and thank you.
Last time I used it is on the charger it came with, but after a moment the phone doesn't seem to work anymore.
My phone has started doing this too, did you find a solution?

Unfortunately not; I tried asking in Mi Forums as well but no one, not even a community rep answered.
this will be my last redmi phone i ever buy or recommend
time to warranty check
i never have any problem wirh xiaomi. best for quality/cost. if i will decide change brand, my next phone will be a pixel. the only one better than xiaomi. in most of cases, your battery problem is caused by a bad charger use. not from phone hardware or software. simply buy a new battery and recharge wirh a good charger from min 20 to max 80. a continuos full discharge process cause battery fast degrade. web is full of articles that talk about this
This is very likely to be due to a faulty/worn out battery.
