Battery replacement - Xiaomi Mi A1 Questions & Answers

Hello,
I replaced battery on my phone 2 days ago and when i put to charge it go to 83% and stop,after disconnect cable and back again then continue few percent and need to repeat few times till reach 100%.
Someone knows what is the problem?
Thanks!

No idea what's happening, you could try to calibrate the battery (discharging until it shuts down automatically and then charge it till 100% with phone shut down), if this doesn't helps you should change that battery for another, an official one preferably.
Hope this helps you.

Already tried that.Full discharge,also i do hard reset and it's same.Only different thing is that not always charge to 83%,sometimes 86,sometims 96 etc.But never to full 100% with one charge.So you thin it's definitely bad battery?I don't know where to find original one.I purchase from amazon here in Germany.

They sell OEM stuff, you can tray ordering from them. Don't know if they will ship it to Germany.
Stupid batteries and regulations lmao.

They send me the new battery,i replaced again and again first changing is to 86% and say it's full charged.
I don't think that the problem is in battery,2 times 2 new battery and charge to same percentage.
Does anyone know what the problem may be?

Well, maybe charging port is faulty? I honestly don't know what else can cause issues apart from battery and charging port...

Hi, I'm experiencing exactly the same issue, but since I bought the replacement battery at a local shop and they installed it themselves, they replaced for another new battery twice, but the issue still continues.
Any luck solving it?

battery must be charged between 20% and 80% to preserve health.

Sure, but it's a brand new battery and therefore your comment doesn't reply apply here.

why want absolutely charge upper 80%, when it's not adviced!

Whether it's adviced or not, a battery should charge to 100%.
The shop replaced my battery 3 times and still doesn't fully charge, and more importantly, it does not last as long as it should. So I just want to know whether the issue might not be the battery.

Every aftermarket battery has this exact same issue. Buy OEM battery, it will charge fully and gives exact same backup as the new phone. I had also bought one from amazon India in march 2021 and it is giving very good backup.
Xiaomi has three vendors for the batteries:
1. Zhuahi Coslight Battery Co. Ltd.
2. Everup Battery India Pvt. Ltd.
3. Sunwoda Electronic Co. Ltd.
Mia1 and most of the redmi phones launched in 2018 or before comes with Zhuahi Coslight Battery and phones launched after 2018 comes with either sunwoda or everup battery. Everup is Xiaomi's new vendor for battery, specially for devices assembled in India.
You can go with battery from any of the above three vendors but I"ll recommend you to buy either zhuahi coslight or everup India because I have tested both. You can look at the attached image for your reference.

Sorry I don't have an answer to your battery issue but I'm looking for some help on how to open this damn phone. And you are obviously someone who has successfully opened yours. I have watched countless videos and I take out the sim and remove the two bottom screws. Then everyone seems to pop the back off with ease. I have a cellphone toolkit and it's just chewing my tools trying to pry this open. The bottom separates a little but I can't get anything else to pop. Any recommendations?

Here are tools it chewed up on the corners. I finally got it with some force and a guitar pick. Sorry for hijacking.

is there any alternative to dragontt for the battery? They couldn't send it to me due to battery shipping restrictions on chile and maybe their country and no matter how hard i search i haven't found any original battery for this phone this far...

One of your attached images is named VBCFT. What is this exactly? Is it a trusted supplier?
VBCFT Original BN45 4000mAh Battery for Redmi Note 5 Pro (4000mAh) with 3 Months Warranty https://www.amazon.in/dp/B085T5NMQ6...abc_4KMBRPV1ZW8FJCC1Q7ST?_encoding=UTF8&psc=1
Does this seem like a genuine battery for note 5 pro. It is from VBCFT

i9500 huge battery problem

Hello everybody,
I have searched a lot on this forum, but I could not find this exact problem and I am getting very frustrated. I had this phone since mid September. The phone is not rooted.
Battery life was great for the first 3 months, than something weird started to happen. I also upgraded to 4.3, because I have the gear, but I do not think this is the main issue.
When the battery is fully charged, it drains more quickly than before and from my understandin looking around Internet, this could be because of 4.3. Ok, but it is not all.
When the battery reaches 40%, it starts draining super fast, like 15% per hour without doing anything. When it reaches 20% the phone becomes really hot and if I reboot it goes into a boot loop and battery goes instantly to 0%. If i plug in the chargher, it doesn't aknowledge it and does not charge. In order to fix it, I have to remove the battery and start charging. Now I can do it with phone on or off but the phone starts to charge super fast, definitively not normal. it goes from 0 to 10% in two minutes and keeps charghing super fast till it reaches about 50%, then it starts to cool off and charges more or less at a normal speed.
Today I unplug it when it reached 50% because I wanted to look at the battery SN, as I read there are faulty batteries starting with BD and mine does too. I tried to see if it is swalled, but it is hard to say without a good one to compare. Well, when I put the battery back in and turn the phone on, the indicator showed 80%!
I am very confused, as there are many factors involved. I read that 4.3 has some issues, I read there are faulty batteries, I read that many people tried to solve with calibration, but other people say it is useless on S4...
Would you mind sharing some thoughts?
Thank you very much!
I wanted to add my batter SN is BD1D606XX. According to this post http://forum.xda-developers.com/showthread.php?t=2504093
it shuldn't be faulty...
Change the battery. Batteries are cheap. Only tc dont buy again one with serial starting for BD :highfive:
Thanks for the quick answers. I live in Thailand, I bet all the batteries here comes from China and starts with BD. Are you positive it is the battery?

I was having the exact same issues and replacing battery solved everything. If you live near a Samsung service centre they should be able to do a swap for you with no bother. Samsung are aware of this issue and should not give you a battery with the same serial at the service centre. Obviously if you order a battery through a third-party supplier you will have to be a little more careful, but if you mention the issue at time of ordering you should be ok!
Best of luck :good::good:
Thank you. Yes, I live close to a Smsung service Center. I had already brought it in because it had stopped charghing, maybe USB ribbon. They fixed it in 1 day under warranty, so I will try to have the battery replaced under warranty. Worst case scenario, I will buy a new one, it is not expensive, but I want to find a different batch!!!

Replacement Battery issues

Hey all...
I recently had to replace my Note 4 battery and have found that the battery is not available... It's been replaced with a different part number. The old one is EB-BN910BBU while the new one has been marked EB-BN910BBE...
What's the real difference? I have been struggling with charging it fully as well... Stops right around 89%. I have factory reset to see how it goes but with the new battery it seems to drain awfully quick.
Has anyone else had any issues with finding batteries? OR does anyone know what the difference in the batteries is?
Thanks!

i have 2 original samsung note 4 battery, both are EB-BN910BBE and they have no problems giving me expected battery lifes. you can try reset the fuel gauge by entering *#0228# in dialer and then press quick start, after the phone lids up you charge the phone until 100% and leave it for sometime.. hope it works.

What does resetting the fuel gauge even do? That doesn't make entire sense to me... does it just re-calibrate it?

Yes both the new batteries I got are OEM. I have tried to charge the two new batteries to 100% but they don't want to fully charge. I've factory reset my phone and wiped the cache... still no dice. But then the question about the differences between the batteries comes up... IS there a difference between the U battery (which is the old stock battery from when I got the phone) and the E battery (which is the new replacement OEM one...)
I was personally told by Samsung that the U and E are region codes for the batteries designed for different models of the phone. They went further to tell me that getting a battery for a different region phone would have unpredictable and possibly bad results if used in a U.S. branded (U) phone.
The true differences I have no clue and have just started looking this true difference due to my battery is now failing and it is a U battery. Some things I have uncovered is the E variant is suppose to be superior to the U variant however, I keep seeing a pattern for those with 'older' U.S. Note 4s, particularly the AT&T models with poor performance from the E batteries. If it is simply bad luck or actual truth I have no clue. Still looking.
I had the issue buying 3 of the E version on ebay not knowing any difference from china. They worked fine for 6 months then completely died. noticing the original battery was U version and still working I found this link. I can confirm the phone occasionally reboot for no reason about 3 months into using them but since the phone is a couple years old I did not really suspect the batteries at the time.
1. Batteries wear out (slowly) sitting on the shelf. Buying demonstrably NEWly manufactured batteries would be in my opinion the trick to successful battery replacement. Maybe this is a problem for the obsolete Note 4. Bought a "new" battery today... Ad says OEM but is it going to be? And will it have been on a shelf for the past 4 years? Maybe. I will see.
2. Charger issue on an old phone? I do not know about this if it is an issue or not.

N910F shooting down at 30% battery

I have a problem with my note 4, the phone shuts down by itself before reaching 0% battery and then it goes in a bootloop or it remains shutdown. If I want to power it up it doesn't pass the first "note 4" screen and it shuts down again.
The only way to power it up is to connect it to a power source. And the charging continues form the percentage at wich it did shutdown. Sometimes does this at 10% sometimes at 20%.
Sometimes after a sudden shutdown it powers itself up and the percentage is 0% and shuts down again, but if I plug the charger it continues from the percentage at wich it shuted down (25% for example).
I read somewhere that buying a new battery will do the trick. So I bought a new oem authentic Samsung battery but the problem is even bigger now. The new battery sometimes shuts down at 60%.
I thought the problem is my custom rom so I flashed the stock one unrooted, just stock firmware. The problem persists.
I tried to calibrate the battery using diferite methods, root method, classic method, a method where I type *#0228# in the dialer. No luck.
Another thing is that the new battery it's not at all better at battery life than the old one, it looks like it's draining at the same speed as the 2 year old one.
I found a lot of topics on Google about this problem but no solution.
Should I get my new battery replaced? Some people did this but with no luck.
Please help, I don't want to buy a new phone because I really love this note 4 but if I can't find a solution I will have to replace it.

Where did you buy the "new oem authentic Samsung battery"? In my experience, if it didn't actually come from Samsung or a carrier, it's probably fake. Maybe try an Anker?
It's probably a fake battery. I bought (against my will ) a refurbished Note 4 a couple of days ago and I had that problem. The battery that came with the phone was not an original one. You can verify it by touching it or just looking at it. The original ones have a NFC chip under the label, the fake ones don't.
Before returning the phone i bought an OEM battery and it went down to 0 before shutting down. With the fake battery it would shut down between 18 and 15%.
Buy a brand new genuine Samsung battery mate. If not online go to them Samsung cafes or whatever they are called in your place.
The battery looks like a original one and has the nfc chip.
I bought it from a big online retailer and I have warranty and invoice. I will go to a Samsung service center and ask for a replacement under warranty and if they say the battery is fake I will return it from where I bought it.
I will update the thread when I have news.
Thank you for your advices.

So what's dead / dying in my 6P

This happened to me today while browsing facebook.
My phone suddenly shut down. While trying to turn on, it would get to booting screen and then shut down again. It didn't loop - I had to try each time manually.
I cleared cache and reset it to factory settings to no avail. BUT once I got back home and managed to connect it to a charger (the battery was at estimated 90% capacity), everything runs smoothly. No shutdowns, no freezes - despite the phone getting warm. I stressed it quite a lot and it seems to hold, so I don't think this is related to the "bigger" CPU.
Could it possibly be a battery issue? Could my device be misreading the actual capacity of the battery?
As a sidenote: it did crash/shutdown once I disconnected the charger, but only after 20 minutes or so when I uninstalled a running at that time app.
Any feedback will be greatly appreciated, so I have something to work with and replace stuff accordingly - and hopefully not the entire phone, as I love my 6P.
It seems like it has to be connected to the battery, as it has been now holding (presumably) at 56% charge for over 4 (!) hours. AccuBattery shows the same data as what the phone reads, and now it seems that my power drain is in negative without charging the phone.
Sadly, there are no original replacements available in my country. Only cheap 3550mAh knockoffs that sellers call OEM. They do have Huawei logo, but everyone knows that 3450mAh is the only original capacity (right?)
Update: Nearly 20 hours on the same displayed 56% capacity.
Any help? Please?
No, you are wrong. Those 3550mAh batterys are the brand new ones from huawei. Those are the newest revision of the battery. Dont get the 3450 ones. If the seller is really selling a 3450mAh one, then its probably one of the old ones with the known issues.

Thanks for the heads-up. Just out of curiosity - how do you know that? When I contacted Huawei support, they did not answer me whether the 3550mah bat is a genuine product, or a farce. They avoided that question until they force-closed my support ticket without a proper answer.
First: Because i bought one and informed myself before. Then the new battery ran better then ever before. Even better then when the nexus 6p was new. Its the new batch that is better then ever before.
Second: you can read more about this topic in the correct forum thread about that: https://forum.xda-developers.com/showpost.php?p=78453441&postcount=1023
The thickness of the cable does not matter that much. Something you can care about is the weight. But this is something you can check when you got the new battery and also took the old one out.
To have longer battery life dont use the original charger. Use max a 5V 2A one. For example from a older Samsung mobile phone. Those have good electrical efficiency.

Thanks again.
For the 3 years I've bee using my 6P I never had battery life issues. In fact, even now the battery is holding well, despite the stats showing that my battery might be dying.
I came to this forum section looking for feedback on what could possibly be going on with my phone presenting the issues I am having. I am no mobile tech unlike many of guys around here. I might budge then and hope that the local Huawei repair center in my city will be of more help than the official Huawei support.

Replaced battery, still old bad capacity.

S7 edge exynos bought in Norway close to release.
So I finally got to replace my battery after using it for about half a year with minor swelling. Accubattery reported it at 64%health with about 2200mAh capacity (design capacity is 3600).
After about 10 charges with the new battery and some "manual benchmarks" (you deplete it totally and charge it to 100 and some additional minutes to see how much goes into the battery) I still only got about 2400mAh so I went back and got them to switch the battery again (not official Samsung service center, but it's original OEM parts).
New one (2nd replacement) seems to also max out at 2400 after a couple of charges (and yes I've tried resetting phone and wiping cache partition). When I go into the testing section in the samsung members app it goes through my phone looking for problems and it states that the battery health is bad and should be taken to a service center for replacement, but this battery is totally new.
Atm, I'm trying the re-calibration method of depleting it totally, on and off on and off, then to 100% and down again and up, but I doubt it will work.
I've also put in an order for the galaxy A70 which I get for basically nothing (1700NOK - 191$, normally costs 4700NOK - 530$). Unless the replacement battery sorts itself out I'm gonna have to admit defeat and switch from my dream phone.
My theory is that either my mobo has some weird ass issue or there's some systemcarememory that hasn't reset and it treats the new battery like the old not letting it charge as much as it can as a safety. Tried contacting samsung support, but no reply.
Any help/advice is welcomed with open arms. Also if anyone have thoughts on the S7edge to A70 switch I'd love to hear em
The only solution is if you are on Oreo you should downgrade to Nougat and then reflash Oreo and if you are on Oreo and have a binary say u4 and you could not find binary u4 Nougat then I'm afraid no solution. No custom Nougat won't do the trick.
