Redmi Note 2 - turns off randomly while charging - Redmi Note 2 Q&A, Help & Troubleshooting

OK, I know that I should be looking into getting a new phone, I've had it for a while. I know that this model has battery life issues. But here is what happens. When it is connected to a charger, it will turn itself off sometime during the charging process. This means that I sometimes miss calls and messages.
The battery life also sucks. It can go from fully charged to 0% in about a half an hour.
I'm running MIUI 9 Global 8.2.1 Android 5.0.2
Any suggestions?

I had the same trouble my Redmi note 2, are there any solutions??????

It's hard to tell the exact problem, but I had the same problem, when 2 years ago I ordered a battery for my RN2 from China, and it proved to be a total disaster..
My phone randomly switched itself off, and the charging didn't even last for one day. I ordered another battery from another shop, and the problem disappeared.
If you just bought a new battery, it may be causing the malfunction.

[Q] Concering batterystats and major battery level problems.

Alright, before you tell me to remove batterystats.bin and move along read this carefully.
I've had my HTC Legend for about 8(?) months now. Around the same time, my mum also bought one. I rooted mine, flashed CM 7.0.0, up to the newest nightly now. She left it as she got it, only upgraded to Froyo when the update came out. Everything is working great, except for the battery statistics.
Around 4 months ago my mother first complained about her battery not charging to 100%. It got worse over the weeks, and the battery level also started dropping faster and faster. It has gotten to the point where, when she gets it off the charger in the morning, it's around 52% (Even though it's been charging for forever, and should theoretically easily be on 100%). After about 5(!) minutes of using the phone, it will have dropped to a 2% battery. Battery life, however, is hardly suffering. She can just walk around with a 2% battery for the rest of the day. Obviously the batterystats are totally ****ed up. After 2-3 months my phone started doing the same, except it does it less severe. I can only charge to 50~60% as well too.
Around this point, I started looking around, and found about how android saves it's battery levels. I rooted and flashed my phone, and using fake flash, I booted into Clockwork recovery, mounted /System (S-on phone, can't edit system when phone is on, still no s-off for hboot 1.01..) and removed the batterystats.bin. I did in a couple of ways now, including the build-in option and using Android Commander. My phone, however, still won't charge past certain numbers.
Now my questions to everyone here is: Did anyone else have problems like these? Any solutions you'd like to suggest? Are batterystats/total voltage also saved somewhere else?
I'd like to point out that the battery itself is not damaged or anything. When my mum's phone had these problems, and mine didn't yet, we tested her battery in my phone, and it would charge to 100% just fine, and the levels weren't messed up.
Her problems started around the time she flashed Froyo from the official update. I can see how flashing a new rom messes up the batterystats.bin, but apparently that's not the only file being wrong?
Any suggestions are VERY welcome.
Tl;dr: Phone battery won't charge past 50% or so, battery level drops to 1% in 5 minutes.
EDIT 1: My mum send her Legend to HTC to get it ''fixed'' THREE weeks ago. She got it back today, them saying it was fixed. After a good 10 hours in the charger it still won't go to 100%, and after 30 minutes the battery levels dropped from 70% to 1%. I think it's quite shocking how HTC can say something is fixed without even trying to charge it to 100%.
you can try this, can't hurt
Turn your phone on and charge it for 8 hours or more
Unplug the charger
Turn your phone off and charge it for one hour
Unplug the charger
Turn on the phone and wait 2 minutes
Turn your phone off and charge it for one hour
Unplug, turn it on and use as normal.

Thanks for the reply,
sad to say I've already followed steps like these atleast three times. Including charging without entering pin, when off, when on, etc etc. Still, thanks for the suggestion.
no such problem yet ... but i'd be interested to know if you were able to resolve it... it cant be a coincidence both you and your mom 's battery levels acting up.

Could be so, but I don't think we're the only people in the whole world to have this problem. I'll keep this thread updated with any information I might stumble across and any other solutions tried. If anyone could tell me where the maximum values for the battery are stored in android it'd be great, seeing how deleting the batterstats.bin file didn't help, there must be another file in android tracking battery..
Hi,
so you're not alone. My Legend is showing the exact same symptoms.
I bought my Legend used via ebay and the seller told that the battery won't fully charge. No problem i thought, just buy a new battery.
Even with the new battery it won't charge more than 60% and it decreases to 10% in 5 minutes.
Just had a test. Even with 60% power at the beginning and 10% after 5 minutes it still was working for 80 hours!
unfortunately i don't know when the probs started to occur. My legend is also with the official Froyo flashed.
regards
Mario

Everyone seems to have this problem since Froyo. HTC fixes it by replacing the motherboard, which basically means they replace 90% of the phone... So basically, there is no real fix around. :/
seem like hardware fault..

Could be so, but it seems strange as the problem starts occuring after flashing to froyo. [Even though going back to eclair doesn't seem to fix it..]

Battery Too Hot Notification

So lately my 1.5 year old Galaxy Alpha running Lollipop (never rooted or modded) started having poor battery life. It used to shut off at 1% battery life. But started to die at even 15% recently. Now this past weekend I was on vacation and a few times the phone died at approx 35% and wouldn't turn back on without a charge first. And when it did come back on the time and date were very!! far off although I was in air plane mode but still seemed odd. A few days later I had it plugged in over night as I always do and saw that the phone was very hot in the morning in my hand. I unlocked it and a notification was up. Cant remember word for word but something along the lines of "battery too hot to charge". It would not charge, I've tried to pulled the battery and reinsert it etc. The odd time it will show on the screen that it is charging but it is stops very quickly. Is this normal for a 1.5 year old battery? Will a new battery solve this problem? I've had no issues with the charging port on this phone. The only problem I've had with this phone is the fingerprint scanner but I've opted to just not use it.
Basically I am hoping someone else has had similar symptons. I hope its not hardware and hoping its as simple as a new battery. But hate to order one and wait a week to find it hasn't helped. Thanks so much for reading this and hope to hear from you guys!

I've had mine since it was released and have never had a heating problem, even with the original battery.

Gs2 won't hold charge

I get service from Qlink. They sent me a refurb as all their phones are refurb, Sprint Samsung Galaxy S2. It came with 8 or 4gb and a 1400 battery or something. A much smaller battery then the retail phone.
Ever since I got it, it won't hold a charge. I don't remember if this started right after I got it because it took me a long time to notice it won't hold a charge. I'd charge it and when I would shut off the phone and try to turn it on a few days later it wouldn't boot. I'd have to charge it for hrs before it'd even boot. When I shut off phone it would always have over 70% battery. Then I notice it says connect to charger even though it is.
Then all of a sudden it stopped charging. I have a 4 port smart charger and cable that has no problems with my other android phone which is an unlocked Moto X Pure or my iPhone 6s Plus.
I ordered from Amazon a sprint galaxy s2 battery. Got it. Plug in and charge many hrs. Turn on. Battery shows about 93%. Turn off phone. Les then two hrs later I turn it on and lost 4% charge to 6%. That doesn't seem right. Turn off phone. Next day phone won't turn on. Hold power and vol down says no battery power. Leave it charge for hrs. Won't turn on. Finally it turns on. I notice battery going down 1% every 10 minutes or less. Not right. Just sitting there.
Then I notice it looses battery % even while charging. % went down. Now when I try to charge it don't work. It powers on by itself. Says connect charger. Shuts off. While later it powers on again and keeps repeating this every so often.
Also when it was on once, it opened calendar even with me not touching it. It would like open it and go to home screen by itself. This after a factory reset.
Now it won't charge. Just does the above turn on then off every so often.
I am clueless what's going on. I wonder if I must get another phone which cost $25. They send anything. All used crap non hd phones. Qlink is a lifeline program thing.
Install android n, of that doesn't entirely solve it, get an unofficial high capacity battery.
Found the original charger and cable. Now when I charge you see the big battery with dots under it when the phone is off. So that's good. Why don't you see this with other chargers?
Battery now seems to work and hold the charge. I don't get it.
I don't think the phone can update to any newer then what's on it now. It's 4.something. Nothing of 5.0 when you check for updates. I think the phone is too weak for 5 at good performance but I don't know.

I think he meant installing a custom ROM. There's currently one Cyanogenm... Lineage OS 14.1 for the Galaxy S2. It is based on Android 7.1. If you are curious, check out this link: https://forum.xda-developers.com/showthread.php?p=68771297
Nice to hear that your problem seems to be solved! I am a little bit surprised, as I often used different chargers without problems.
Why won't it hold the charge long?
With official cable and charger and batter it came with from lifeline program it looses full battery while powered off in like 3 days. And gone from 94% to 87% in less then 30 minutes.
What's going on?
Then one week it'll be fine.
Me too, i have the same problem too , and I'm charging my phone almost 4 times in a day

Redmi Note 4 Dead battery?

Hi to all.
Strange things are happening with my battery, phone...
In last few days my battery can't hold much. It drains very fast, i mean very very fast. When i use the phone, maybe it can hold for 1 hour and more. Just browsing, chat, nothing special. When i put the phone to the charger it's also charging very fast, and even,it's skipping the numbers. For example, i'm looking at my phone, it's 19%, and for another moment it's 21-22%, maybe 15-20 seconds difference, literally you can see numbers skipping. Also, for example, i have now 45% battery, it's not on charger, and the second moment when you look at the phone it's 48%, that usually happens when the phone is in sleep or stanby mode, call it whatever you want.
I won't try flashing ROMs , factory reset etc... because the same thing happens when the phone it's turned off. I mean, the fast charging and skipping problem.
I don't have any problem with heating. The phone works as usuall, it's fast and everything. Well, from my earlier experience, the battery is probably dead. I even ordered a new one, but it will take a few weeks to arrive from China.
I will post also a screenshot of battery stats, and i will mark the parts where you can see the percentage of battery going up, even when it's not on charger (what the heck).
Does anybody have this kind of or similiar experience/problem? Not on the same phone, i meant in other phones also. Could be there some problem with motherboard, charging, or something else?
Here's the screenshot. I hope everybody will understand what am i talking about.

I'm wondering if you have a hardware issue, you stated in another thread your battery​ was charging in an hour, now that is very unusual to me.
It should be around +/- 2hrs with phone switched off.

Well i'm also wondering. I will found out probably soon, when i get the new battery. From the start, when i bought the phone it always took less than 2 hours to charge, later that changed a little bit. The charging got faster over time. I was never thinking to much about it. The phone is really useless now, at the moment i don't have another phone. I was thinking buying a new one, but i will probably wait to see the results when i change the battetry.

I'd be interested to know when you do replace it, whether it's just an inheritly bad battery or something to to with the charging PCB.

Hi to All, and Hi to you Wilderone!
As i already wrote, i was waiting for the battery to arrive, and it arrived yesterday. I replaced the battery, it was charged already to 41%. For now, the battery is holding quite good. No "problem" while charging either. It takes now approx. 1 hour and 50 minutes to charge from 0 to 100%. Before, it was approx 70 minutes. I can't tell yet anything about the battery life, because it was charged only one time, and i didn't use it much from yesterday because i was working all the day, but i hope i will be able to post battery stats in a few days. So i hope that it was only bad battery, and that there is no problem with motherboard or with the Charging PCB. Will keep you informed.

Mate 10 Pro - Battery percentage out of the box

Hi all, this may seem like a strange question.
Just got a new Mate 10 Pro, and when I switched it on for the first time the battery percentage was at 42%. I've read somewhere that as a general rule for new phones, batteries are normally between 50 and 60% out of the box, and if it is anything less this could be a sign that the battery is faulty (e.g. can't hold charge for long). Also my last few phones have actually been around 50-60%, so was a little concerned to see it at 42%.
Does anyone know if this is true or what I've read is a load of rubbish?
Don't want to return phone but will if I have to.
Thanks.
I had mine with 34%. Some even got them at 0%. Try charging and see if it charges fast. And then use the phone. If all seems normal than there's no problem.
But that's is really weird,i saw 3 new mate 10 that came with dead battery, I'm sure that's not normal.
I'm thinking that while the phones were shipped they turned on automatically and drained the battery.
..
I spoke to Huawei and they say they've had multiple cases of battery being below 60% due to phones being accidently turned on in transit. They suggested charging to 100%, then leaving phone in airplane mode overnight with all apps closed and seeing how much the battery drains. Anything above 96% is a good battery apparently.

Same here!!!!
Completely dead!!!!!
Mine was stone dead out of the box. Zero %. !!! Charged it up.... took an hour and a bit to get to 100%. Used it for just over a week now and battery is fine and dandy... Drops a couple of percent overnight... Lasts forever during the day. Really is a monster battery. Seen quite a few reports of zero % out of the box (which is pretty unusual....most phones I've had seem to be about 60%) but doesn't seem to be an issue... maybe that's how they ship them now...for whatever reason ???? Anyway, seems to be a non-issue.
Same thing. My first mobile with dead battery after I opened box. But about 10minutes I had same percent I can use.
Odesláno z mého BLA-L29 pomocí Tapatalk
mines had 12% i never switched it on plugged in the charger as i like to start with 100% battery while setting up a new phone.
Guys, the battery measurements seem to be screwed up at first. Even when I switched phone off, it drained like 10%. However, after about 3 full charges, everything is great. Still at 100% in 2 days (yeah, I left it off for 2 days just to check). So, my theory is just that the phone needs to calibrate its measurement of the charge percentage.
My pro came with dead battery too.
Same here, dead battery. After first charging, is working just fine.

Mine was around 60%
My Mate 10 standard was at about 87‰.
Mine came dead too, i was very concerend and also started a new thread about it here. Relived to see that many have the same "problem" so far I am loosing about 10% overnight with wifi and all enabled. Seems a lot to be honest but I am going to try it for a few weeks to see what happens...

With wifi, there might be some background app processes running that are draining battery life. Try it without wifi. You should lose less than 5%.
mine completely dead on arrival...I also notice that the power button easily press n get the phone to restart few times for me...
They're supposed to charge it till its full on the first time to optimise it
I'm surprised so many Mate 10 Pro's have been delivered dead or with minimum percentage. Mine switched itself off at 10% so seems like there is some calibration issues too. Hopefully these will work themselves out after a few charges, not sure if it's because the phone is so new (maybe first batch niggles?), but didn't have any of these issues with my Mate 9.
How are people's batteries that came dead or with minimum percentage performing so far?

Very well, no issues with battery life so far. Mine came dad and acted up quite a bit in the beginning.
