Redmi Note 4 Dead battery? - Xiaomi Redmi Note 4 Questions & Answers

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.

question about reconditioning battery

yesterday after flashing nero 5 i wanted to recondition, so while sleeping at night i charged my phone to 100, and now during the day time im trying to waste the battery, but during that i got caught up on adb and connected my charger, and left it there, now its back at 83% battery, does this mess up the reconditioning process? or do i have charge back to 100, then do it all over?
anyone? please lol

what you should do is drain it all the way untill you cant turn it on anymore and leave it chargin all night turned off, and when you wake up turn it on and let it charge untill its full again, then boot into recovery and wipe batt statt , and you should be good to go mine last about 20 hours after i did that

I did just about the same with mine, minus the chargin all night turned off, and I am getting about 20-24 hours with mine, which is more than I need as I plug it in every night

me to im near a power source or computer all the time so
What you should do is keep letting it drain until 1% or so. I don't think you need to let it die completely. Charge to 100%. Boot into recovery and clear battery stats with the charger still plugged in. This is the important part. Then drain the battery and charge to full. Then you should be good to go.
question, after draining to about 1%, does the phone have to be off? and can i use the phone just a bit while its charging?

The general consensus is that when you condition you should charge the phone while it's off. I don't know enough about battery chemistry to tell you why. Just do it to be safe
Battery "recondition", actually does not "recondition" the battery, it is a trick just to get more accuarte readings (that's the only reason you reset STATS)
The battery may not charge up to 100% and will never do, just following this procedure. It will just say it is @ 100% when you actually are @ 85 or 87, that's why the sudden "jump" you see.
Best way to try to get better readings is charging the battery till it says 100%, unplug it and plug it again a couple of times until it fully charges and follow the same procedure.
Once yo did this a few times, turn off phone, reboot in CWM (with the phone never unpluged) and clear battery stats. turn off phone and unplug,,,,
You will got at least more accurate readings

Android Police did a piece on plugging and unplugging your phone to get up to 100% (it's called bump charging, see below). They recommended that you NOT do it because it doesn't get you much additional juice and you wear your battery out faster. Normally I just charge my battery up to 100% (no drain), wipe the battery stats, unplug and go until it dies. I use it while it's plugged in and still get a full day easily out of my phone.

I hate to be the bearer of bad news. You can not condition a Lithium-Ion battery. All you are doing is wearing it out prematurely by deep cycling. Every time you do this you destroy your over all battery life a little.
I have posted about this here in several thread, and I am getting a little tired of having to tell people NOT to do this because they don't search for themselves. Do a search on the forums for deep cycle li-ion and see for yourself.
If you want to know the technical reasons why, Google is your friend.
so we just deal with what is perceived as faster battery depletion?
Im asking because As i have posted on another threat I am a complete freak about my battery life.
Basically yes, I have 3 batteries to go around all day, although I us the car charger, if for any reason one day I take the train to the city, I will eat up 2 and a half batteries in a day.......
I had 3 batterys for my hd2 I need to get 2 new batteries for my vibrant. I guess im just tripping because I tried and over clock kernal and it seems like its dying faster while the screen is off

Yea, just chill. It is all in your head. From ROM to ROM, usage pattern to usage pattern, and app version to app version - there are just too many variables to worry about. Just use your phone, charge it when it needs it, and relax.
Your phone's battery is going to get less life as it ages. There is nothing you can do about that. Also, it will likely only get 2-3 years before it needs replacement. If it gets less than 2 years it is because you have been "conditioning" it. which ages it prematurely and also causes how long it lasts between charges to shorten as well.
Li-ion does not have a memory, so conditioning is an inherently false concept. Recalibrating the devices ability to read the battery is a different story, but it should only be done if it really needs it (like it thinks it is at 1% when it is at 20%), and it should never be done more frequently than a minimum of 30 charge cycles or if you charge it once a day when you go to bed no more than once a month. Less frequent is better.
So sorry, you need to find something else to obsess about. Might I suggest getting Team Whiskey to make BlackFroyo the default theme, use the 5 bar signal meter, the larger numbers on the battery, and the hacked camera the used the power button to take pictures. That would save all of us some time.

Nice link - try reading the stuff by the engineers that work with batteries for a living now instead. You do know eHow is just a site where any idiot that thinks they know something can post, right? Are you going to reference wikipedia next?
BTW when you recalibrated your battery and got 6 more hours, did you do anything else that might have explained it? You know like flash a new effing ROM? That might possible change a few things to do with your power usage.

it was a joke
and no, i flashed Nero 4.1, and then used it for a week thinking the phone would adjust to the battery and new rom, it didn't.
then i thought i'd just take a chance and recondition my battery, it was my first time, and it worked out great.
and trust me i'm a heavy user.
roughly 300-400 texts per day.
20-40 phone calls
music about 5 hours per day
and i play soem games, but thats understandable because playing dungeon defenders uses like 30% battery per hour bcz of the high graphics and such.
a bunch of app downloading.

[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..]

Lumia 800 battery fix maybe?

Hi this is my first ever post so please bear with me, my lumia like many others suffers from ridiculous battery drain I have the new software and yes I can now charge to the max. However the battery cannot last the day out until I discovered this. Most people I know continually top up there battery, but if you just let it completely die then do a full charge overnight you may like me notice a massive increase in battery life, I have changed nothing about the way I use my phone the only difference is it now lasts 2 days easily.
The figures quoted in battery saver have not changed but as the day goes on the time since last charge goes up but so does the estimated battery life.
My phone is now IMO fantastic.
Maybe if you tried this it might work for you too, do hope so.
One word of caution when the phone has died the phone cannot be switched on until charger has been plugged in for some time, in my case about 20 minutes after plug in the phone switches itself on.
Please try and maybe you will also have the most amazing phone too.

I think I experienced something similar. I then flashed the new firmware and am back to lower battery life. Need to take the time for a few discharge cycles.
The problem with this approach is that some Lumia 800's cannot turn on after a full discharge. People have gone to great lengths to be able to get a tiny bit of charge so that it could power on. Some people have had to send them back for repair.
Question to TS. Do you let it completely die every time now or can you charge it whenever and still get the great battery life?
battery fix maybe
Hi after letting the phone die I have not done it again since, I just top up as needed or at night just as you would normally do.
Hope this helps.
Okey. When you say "completely let it die" do you mean letting it drain and turn off. Or do you start it once again after the first turning off and let it die again?
battery fix maybey
Just use the phone till it turns itself off, then plug in charger, this is when you may have to wait for the phone to switch on, mine turns itself on after about 20 minutes, charge as normal then use as normal, charging as you would normally do.
Good luck.
I did this once intentionally about two weeks ago. Did not notice any difference really. I do not have "bad" battery life to begin with. Not great either though. But it easily lasts a full day with heavy usage which is all I need really.
12 hours since last charge. 73% left on battery. I have used it "normally". About 10 quick calls. A few messages. Browsing on the marketplace installing a few apps editing contacts etc...
I'm pretty heavy on my usage, too. Lots of Mix Radio, sometimes played via bluetooth.

Battery Issues whilst off?

Hi All,
Quick question to see if anyone else has noticed this at all?
Last night my watch was on 57% after a day of usage which I thought to myself, Great if i turn my watch off over night it will last me the next day aswell,
But upon turning my watch on this morning, my battery had dropped from 57% down to 23%,
Has anyone else noticed or had this happen?
Thanks!
Why don't you just let it charge over night? You will need the charger to turn it back on anyways, it's not like this would be practical or anything..
But no, I haven't tried turning it off over night. My watch also goes down to about 50% after 1 day and then I just let it charge together with my phone at night. I love the charger, just put in on there, no need for plugging anything in, way better than all the other methods from Sony and Samsung etc

The reason i dont want to leave it on charge overnight is that it could potentially damage the battery, they havent been out long enough to know the long term affect on the battery life, and as it is a waterproof construction i dont see it being cheap getting a replacement battery, i never leave any of my stuff on charge overnight as to not damage the batteries of them.

modern lithium-ion batteries cannot be overcharged. you're misinformed.. that only happend with old battery technology
the only way to damage the battery is by overheating and for that to happen you would need to charge it more than just a night, more like 24 hours at least. and even that doesn't happen anymore because smartphones stop charging when at 100% and so does the watch.
But when the battery gets to 100% the charger may stop charging but when the battery drops to 99% the charger will kick in again,
Previous phone batteries - S4 and S3 were ruined doing that

so? that still doesn't ruin the battery. it's normal that batteries wear off after some time, but we're speaking like after a year or so. nothing you can do about that. not charging doesn't do the battery any good either. it's best to always charge a little and not from <10% to 100%
So after a year you're happy to pay another £170 because the battery will only last less than a day, I'd rather take care of it and not kill it, like my z2 only charging when dead and not leaving it on charge overnight I get 3-4 days battery on it currently yes it's only been out for a while but I don't see anyone else getting that usage from it

Do as you think, but charging the phone or watch overnight will not ruin your battery, it just naturally wears off after time. And im sure that when there will be replacement batteries it will be nowhere near 170 quid.
Anyway I am more the kind of guy that charges the phone couple of times a day, so I usually never get below 20% battery. As for the watch, I am going to charge that once every day. Right now it holds up for more than a day so after some time it will be probably down to a day, but as long it doesn't go below 15 hours, yes im fine with that.
But that's the point I'm trying to get across, a battery is stated to last a specific time so why should they not last that time without proper care, not over charging etc..
But maybe that's just my opinion.

To answer your original question, mine doesn't lose any battery when switched off. I turned it off overnight with a full battery and when I switched it on this morning, it still had a full battery.
All I can think is that you accidentally hit 'reboot' instead of 'shutdown'. I'm sure you are positive you didn't, but it is the only logical explanation. Try again and make sure

Yeah well last night when i charged it, it was 100% when i turned it off, and this morning it was on 99% when it turned on, so i will check the % tonight before i turn it off, and check it in the morning when i wake up, as of 4pm i am on 67% so it should only drop another 10-15% before i turn it off later.
Sometimes the cradle didn't pick up the watch correctly. You can place it in the cradle but it won't charge. Make sure the lighting bolt icon is on the watch

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.

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.
