Hi guys
My Redmi has experiencing a bit odd behaviour every time I charge his battery
I always do full charging cycles, from 0 to 100%, and than use it till it full drains.
I usually charge it with the phone off
The last couple of times a strange thing happened: I fully charge it from 0, with the phone off, but when I turn the phone on the battery level shows something in the 70% level, the last time it was 77% only., This time I connected it back to the charger, and it went to 100%
I already installed a battery calibrator, but this keeps happening now
I use the original Xiaomi charger, or a Sony charger.
My Redmi is running the stock Marshmallow ROM - that's another funny thing, my phone simply has no updates to Noughat or ahead, I'm in Portugal those updates should have already arrived
So, any suggestion from you?
Regards
Antonio
Most probably your device has fake MIUI vendor ROM. I am guessing this because there's no update you got on your phone.
Redmi 4X has been updated already to MIUI 10 based on nougat 7.1.2.
I would recommend you to backup your all data on phone and clean flash latest stable update and restore back everything.

I'm not very worried about using latest ROM's on my phone, the charging issue is the the thing that annoys me the most, I'll think about updating my phone if and when the other problem gets a solution.
Does anybody has a say on this matter?
You should try to keep your battery level above 50%. Lithium batteries need charge to keep their effectiveness.
Only do 0-100% maybe once a month. When you do, charge the phone when off to 100%. Boot phone, if it is below 100% at startup charge more until it reaches 100%, then restart. Continue this until you get stable 100% or consistently close to it.
Battery calibration apps are trash, don't even bother with it.

Okay here is my thought on your situation.
I charge my phone upto or around 90% to 95% and recharge it when it falls down to around 20% to 25%, due to my daily routine and usage i do get around 20% battery remaining almost everyday and in very rae case it goes below 10% till now for me it never went shutdown due to battery gone full zero.
I have Redmi 1S and i charge like this and i still do get around 2.5 hours of screen on time on it which is great considering it is 4 years old device. and i am still using same original battery came in the box which now shows some ageing signs since it has little bulge on it and sometimes phone shuts downs it self and after turning on it looses 10% to 15% of its charge.
it is recommended to keep some battery % left in phone for good battery health.
over time battery does loose its capacity.
you should consider changing how you charge your phone dont let it charge fully or let it drain fully. when battery drained out completely it does takes some time to hold some charge and when you charge you phone fully the battery does goes back to 99% and goes again to 100% since it is already on charge, this keep happening until stop charging which affects battery capacity and the charge it can hold.
i think in you case this issue happening due to the how you charge your phone.

Thanks for your input
That doesn't make much sense to me since I charge it almost every time with the phone off, so once its 100% the charging process stops, and there's no way the battery should start draining because the phone is off - and even if it was on, it shouldn't loose 25% at once . If it was hardware problem, with the battery getting worn, I would never have the chance to drain it to zero slowly (it would shut down at 10% or so) or get an 100% charge level - and once I turn the phone on, he does go to 100% without any problem, so the battery seems to be ok
I do the same process with my 5 years old Sony Z1, once I charge it 100% I turn it off, and once I turn the phone on again, the battery charging level shows 100%, even If I do it a month after last charging. This old guy's battery is showing first signs of age, nowadays I get half the time I used to, but not that dramatic thing of not be able to do a phone call with 10% battery level.
So, same charger, same process, why my Xiaomi is behaving differently than he used to?
Why the charge level indicates 100% and once I turn the phone on, it shows 70 something %, and than charges without any hesitation to 100% ?

The I am not sure why is that happening suddenly using same process.
I know you've said not interested in flashing ROM just yet but maybe consider changing ROM to official Global/china stable MIUI 8 or latest MIUI 10.
Possible reason for this hardware/battery or software issue.
Maybe get device checked at official xiaomi service center or contact them on customer care support. They should help you the best.
I'm trying to do the update route, but I'm not very confident on my tech skills - and the downloads are failing all the time.
What's the best/easiest way to update my 4x?

Hi
Thanks for your reply, I ended up finding there's a MIUI tool available on playstore with ready updates for most phones, so I just downloaded the updated ROM directly to my phone and installed it.
It even kept all my apps and files, I did some backups in the process but never had to use them
Thank you all guys
have you tried
1) power off the phone and then after few seconds power on
2) charge using a different charger + different cable when your battery level drops below 50%, just to check if the phone still charges to 76-77% or if it charges to 100%.
3) if the above fails you need try factory reset or flash latest MIUI rom

In addition to my other issues, refer to thread http://forum.xda-developers.com/viewtopic.php?t=43272 (ERROR: ITWriteDisk - An internal error occurred), I have noticed that battery meter on my 8125 flashed to the the imate aku2 rom, is always at 100%. I'm unsure whether this will effect charging since when I plug in the charger, the led turns green immediately and stops charging, and I have had the device turned on for 4 or 5 hours disabling all the power saving features, leaving the backlight on, turned on BT and wifi, and its still at 100%... either its a great battery, or somethings screwy.
small update.
after about 5 hours the battery meter started to drop quickly. Although this is good, the problem that comes up for the first 5 hours, you cannot charge the device as it thinks the battery is full.
Am I the only one experiencing this?
same here.... after 24 hours battery meter droped from 100 to 94
bafore it was 90 after 24 hours
maybe they improved something.. thats why it does not go so fast as before
I think it is the fact that the new rom seems to be much better with power consumption. I am getting almost a 50% gain between charges due to my pattern of usage!!! Very happy!
I'm more then happy at the battery improvement, what I am not happy about is that if this is a bug (granted there is improvement), the problem becomes when charging the phone, so I have it for 12 hours, its still showing 100%, I have an offsite meeting the next day, and would not be able to charge the phone for the entire day, the battery will start to drop very fast since the phone thought it was fully charged, when it really was not... I'm confusing myself here, but I think you understand what I am saying.
Also, while my battery was at 84%, I did a soft reset, when the phone came back up, it showed 100% battery and refused to charge... this is a problem.
You might want to inquire about a replacement device or battery - in case it's not the sotware.
My laptop has this issue. It's always been on external power and somehow that's weirded out the control circuit telling the machine how full the battery is. It will read 100%, but it's actually at 75%. Then if I disconnect it, it will go down to 5% in 8 minutes. However, it will happily run for 3 hours+ on that last 5%. Similarly, if I hook it back up to the charger, it goes to 99% (leaving the battery indicator light amber) in another 8 minutes. Takes many hours more for it to get back to 100% (making the battery indicator light blue).
With any luck the control circuit will be in the battery (I believe it is), and the easiest way to check is to exchange your battery for a temporary new one and see if the problem goes away.

Agreed.
If you think your battery is stuck - just do this little test.
Turn on Bluetooth, WiFi, make a GPRS connection, and set back light at 100% and don't let them turn off or let the unit power off. The battery should drain pretty quickly in this senario.
I thought mine was stuck, but it dropped 5% in less than 10 min in this mode.

I'm not so sure its the battery.. another issue that I just noticed, is taht even though the backlight is turning off, the screen itself is not turning off after the designated time I set...... this is rather bothersome as if I forgot to manually turn off the screen.. it remains on constantly.
Even with my original Qtek 9100 EN ROM, the screen doesn't turn off - only backlight. If you want the screen to be off, you'd need to go to Standby, or use a third party utility to turn the screen entirely off.
Although lithium batteries are best kept at a full charge, they should be periodically drained to recalibrate the fuel gauge.

I was also having this problem but after about 2 days use it began to go down. My G3 device seemed to hang at 100% and drop quickly after it hits 25%. I believe this must be a hardware issue as I now have a G4 (setup identically to the G3) and it does not have this issue.
i am having the same issue but i believe it the battery because my phone 8 months old and if you read the battery thread it has all the same issues your having
Hi
Got an extended battery for my G1 a few days ago from ebay.
The problem is, the phone doesn't recognized it after I switched the battery. I had the same charging % as the previuos battery right after I changed it (even though I never charged it) and the max use time in Battery time lite is the same....
Any ideas ?
Thanks,
Nati
bad phone ? my ext batterys work fine from ebay
is there any way I can be sure ?
Maybe it a firmware thing ?

I had similar issues when I first got an extended battery (Seidio 2600mA). After performing the steps below, I had no problems at all. I hope it works for you.
Try a COMPLETE drain and recharge cycle, a couple times.
Run the battery down until the phone shuts itself off, restart the phone and let it run until it shuts itself off again. Repeat until it will NOT boot anymore. This will take a surprisingly longer time than you think. Load up your music player, youtube via 3G, etc... kill that thing.
Once the batter is so dead that it can't even load the splash screen for a boot charge it up, but do not turn it on. Let it charge up to full for a few hours (usually four will do it) and turn it on. If it's not at 100% yet, let it charge for a while longer. When it's at 100% take it off the charger and run it down again like before. Run it until it is totally dead.
After a couple cycles like this, you shouldn't have any problem with your phone and battery giving accurate charge status results and operating as it should.
I've read, from a few sources, that between the internal monitoring on the battery works, and the way the G1 reads the battery state, that this complete drain and recharge cycling helps to establish baselines for "empty" and "full" and keep them synchronized. If your phone has never seen an extended battery and the battery was at partial charge when inserted, it may not have been able to accurately gauge the minimum and maximum extents and give faulty readings based on prior battery data.
That could be wrong, and I don't know for sure. But, a complete drain and recharge never hurts anyway, and in my case it actually seemed to solve the problem for me.
Good luck!

My battery never charges above ~76% when plugged in. After rebooting however, it is very much at 100% and lasts for a good amount of time. This is not necessarily a question, but I wonder if others are experiencing this too and if there is a fix? Read below.
I noticed that my battery life got very bad after installing custom roms. I also found out that this happened because I sometimes kept the phone plugged in while flashing, something that totally screws up the battery reading. So, I followed this guide to calibrate my battery and it worked.
Now, whenever the phone is plugged in it NEVER goes to 100% when charging. Maybe 80% if leaving it for a while (10 hours overnight). I'm worried about frying the battery. Is there a fix?
It is only a matter of presentation. It actually doesn't mean your batt is broken. Plug it and charge it overnight. Then discharge only for few percent and plug it back in. It should go to 100%.

Thanks, I'll give it a try.
What I'm concerned about is if the phone "thinks" the battery isn't recharged and keeps squeezing juice into it when in fact it is full (which a reboot will show)? That's not good for the battery. It should go into trickle charge after reaching 100%..
The process described in the desire forum is also known as formatting the battery. In fact most of battery manufacturers (lithium battery manufacturers) recommend doing this in a slightly different way:
Before first use:
1.) Before powering the device on, plug it in and let it charge until the LED is green (fully charged)
2.) Then take the battery out of the device and wait an hour (to make sure all the chemical processes in the battery are as idle as possible)
3.) Then plug it back in, while still off and let it charge untill green LED
4.) use the device....
You can practice this slightly modified with first step being:
Discharge the battery (by normal use)until only few percent are left (1 - 5 % are OK)
I've done these steps with my Mugen extended battery and I was getting around 4 - 5 days on Legend, now I'm getting 2 - 3 days on Desire S, but the ROM isn't very optimized yet, I believe it will be better in time...
Just one thing... Why is this in Development!?
No Idea.....
can mods move this?

Definitely did not solve it but at least the battery performance is ok. It just stays at 78% for a few hours drops from there. Very weird but as long as the battery doesn't get broken I guess it's ok.
Do you have some 3rd party battery installed in your Legend? I have one 1,5 Ah in mine and it is acting the same way. It doesn't bother me too much coz it was cheap... it lasts 48 hrs with data always on and moderate usage. I noticed this that when I charge it overnight and it reaches 80%, unplugging it stays at 80% for several hrs and just after it starts dropping if I plug it again, meter reaches 100%. It's weird but as I said I can live with that
I've got exactly the same issue with stock 2.2 ROM. I've never rooted or CM my phone; I was wondering if CM would do it, but doesn't look like it.
android forums /htc-legend/265545-battery-doesnt-fully-charge.html
(sorry, I can't post links; maybe an admin can fix the link for me?
This seems to indicate it's a phone hardware fault and requires a new Legend to fix! My big worry is, as stated, that the charging light never goes green; therefore is pumping lots of power into a potentially full battery.
Hello everyone!
This is my second post here...but I really felt like I had to take attitude this time and actually do something.
So my samsung galaxy s3 is acting so weird that I can't use it without something bad happening for one day.
So...first of all...my battery doesn't last more than four hours straight if, for example, I am listening to music.
It literally goes down about 1% every few minutes.
Also..there is something really weird happening with my battery even after it completely shuts down. Lets's say I am on 1% and the phone shuts off. After the screen goes black and I plug it in...the charging screen appears and the battery seems to be half charged. I open the phone again and it is already at 45%. All this operation takes a matter of seconds...but still it goes from 1% to 45%. After the phone is up...this percentage starts to go down even faster than before...in the end my phone shuts down again...and this time it starts to charge from 0%.
Today it shut off...and when I got home and plugged in the charger it didn't do anything...i just left it like that for about 10 minutes then tried to power it on without the charger being plugged in...and it worked. After that it started to charge. I have no ideea what is happening.
Also...my charging time is really big. I do not know why but when I use another charger from a samsung galaxy mini 2 it seems to charge way faster.
That's pretty much all so far. If you need more details, please let me know.
I hope you can help me sort this out!
Best regards!

1.Might be the battery is dead or broken, or its not calibrated. How old is the phone and battery?
2. It seems to take ages to charge my s3 lte too, give us a number in hours how much time you need?
3. The problem where phone wont turn on or show charging when battery is as low as 1%, i had this too, i think its normal, its protecting the battery
4. Do you have overcloacked anything? It happend to me when i had ovecloaced and did benchamark test, the phone froze and battery eas 5% when i restarted the phone, but before it was 45.
Not realy helpful but i am trying XD. Also might wanna buy new battery, its not that expesive
if you are running stock rom with no rooting no anything....100% it's the battery.
if not install stock and see how it goes...if it's acting normal then the mods are the problem...if it's the same it's the battery.
Do a factory data reset on stock recovery. See how that works out first
Starting from factory reset is bad idea - it should be the last step IMHO.
First what in such case we need to check is battery health.
Percentage we see on our phone is weak indicator, because it is calculated
Better to see the voltage in different situations. How to check this (terminal app or adb in console):
cat /sys/class/power_supply/battery/voltage_now
The lowest voltage that device can handle without heavy usage is less than 3500mV (I saw even 3240mV, but with low brightness, no data connection and after trying to make a call phone turned off).
The maximum voltage is obout 4300mV.
When You see 1% of battery and voltage is realy close to 3500mV or battery is charged and voltage after removing charge is dropping realy fast to then your battery very likely need to be replaced.
I bought Samsung Extended Battery (3000mAh) and this tripled the time usage than my 2 years old normal battery 2100mAh. You can see that difference in their capacity is much smaller - about 43% biger, but give me 300% much time on battery so old one was realy worn out.
BUT if your battery wasnt used for longer than half year, you can do as follows:
1. Discharge battery
2. When phone turns off - turn it on again, but into download mode (Home-VolumeDown-Power)
3. Leave phone for as long as it turns off again and repeat step 2 till time that Download Mode wont even boot.
4. Take off battery and place it back, and again try point 2 (start Download Mode) - do it until phone will show Download Mode for only 2-3 secconds
5. Again and last time replace battery and charge phone, but turned off
6. When phone will be charged, turn it on and leave it on charger for about one hour
After those steps use your phone lightly and try to repeat whole process one more time but only when the battery will normaly discharge and phone will turn off.
I tried those steps and battery for sure can work longer FOR ONE RUN, but unfortunately it can lead to loss of capacity much faster, but it will be noticable after one year - IMHO its always good time to buy new battery.

Nothing good will come from that procedure. Those steps were useful in the epoch of nickel-cadmium batteries, where the battery had no internal circuits to monitor itself and had a tendecy to uncalibrate. Those stops would force the device and the battery to re-adapt to one another.
But now we're using Li-Ion batteries, and those DO NOT like to be fully discharged. Hell, the device might not even recognize the battery, if it has really been fully discharged.

Okay...so I went to the shop from where I bought my s3 (Orange shop) And they told me to send it to their service and I did so...as I still had it under warranty. It was there for exactly a week and today I got it back. They told me they replaced the battery (which they actually did...I checked that) and the power connector from my phone. The battery it's still not good enaugh in my opinion. Immediately after I got it back...I turned it on and it had 79% battery. In about an hour it went down about 25% (so to 54%) but I didn't used it havely (note: the mobile data option was on). I really do not know what to do. I asked someone and they told me to send it again because this is not normal.
My s3 is running stock 4.3 and used to last waay longer back in the day.
What should I do? I literally got about max 5 hours of use before I sent it and I am afraid this will happen again. I do not even want to think what is going to happen if I listen to music for example.
I turned the phone off a few hours ago...then let it charge up to 59% and then stopped because I had to leave. I used it moderately for about 4 hours and 51 minutes (as my phone says) and i have about 2h and 15minutes of screen on time. My screen is using 50% of the battery and also Android system is using about 17%...chrome 12% Android OS 7% and I think everything else is less important as they use 7%<. After those almost 5 hours...while the mobile data option was on all the time I am at 14% battery.
What do you think? Is it good enaugh? Should I send it back? I really need help!
I am waiting for suggestions.
Best regards!

I think so, the fact that you have the screen on top of Android OS (and not the other way around) pleases me. You had your screen on for 2h15m, of course your battery went down fast
Test it, charge it full, and use it. Normally.
Do this for 2 or 3 days, and check how the battery lasts
Hi,
Using my N6 everyday since mid-2015, I'm considering replacing the battery with some ez30 models available on Amazon/Ebay.
Before doing that, I have a few questions :
- I often read bad reviews about batteries purchased on Internet. Is there a good and reliable place to buy one ?
- How to correctly measure the mAh remaining of my battery ?
- I installed AccuBattery telling me my battery is 91% capacity => 2932mAh out of 3220mAh. Is that reliable data after + 1,5 year of every day use ? I can't believe my battery is still that good today ^^
Thank you in advance
Hello,
Well, I bought my Nexus 6 in March 2015 and it still holding strong.
I also measured the battery with AccuBattery and it says the health is at 89% or 2872 out of 3220 mAh.
I read on some places that normally, batteries lose about 10% per year of its capacity, so I think the data is reliable.
With Android 7.1.1 stock + Franco kernel + encryption disabled and f2fs, I get 4h30 to 5h30 screen on-time, which I believe is on pair with many of the phones out there.

Got above battery installed a week ago, I'll measure this battery and post my findings.
Most batteries can go on a long time as long they don't go bad(mine did).

Any findings to post yet?
Better than the OEM?
Curious if this is a good replacement as it's 3 times the price of an eBay "OEM"...
Hi there I just got my N6 phone back from a repair, they should of replace the battery but I don't think they have, after one full charge from phone being at 5% charged over night using the same app as you guys my battery health is at 48% 1,545mAh estimated capacity ..... design capacity is 3,220mAh before I sent it away it said my battery health was 60% ....do I have to give it a few more charges before I get a more accurate reading or would you say this is a genuine reading.

UPDATE: Had to send my phone back a second time when it came back after the first charge I checked the battery health and it was 102% and the battery lasting all day and a half, so it seems they didn't replace the battery the first time.
i think this reading is so wrong, how can this be. still using original battery , never replaced.
updated screenshot after battery reset using bootloader logs reset then drained the battery to 0 let it shutdown then charge back to 100%.
does that mean i need a new battery ? @ktmom

Dunno about those stats. They're based on a small amount of data. My experience is based more on actual performance.
If resetting the bootloader logs improved the performance of the android reporting, if the device use time is deteriorating, and you deal with unexpected shutdowns, then I'd expect the battery to be the root cause.
I pushed my battery beyond those points and also experience problems turning the device off and on. The screen would go dark as though the device was off, but wouldn't respond to the charger. Long pressing the power button would shutdown the device. At its worst, plugging in the charger with the device off would not bring up the basic battery charging animation nor turn on the LED.
The original designed use for the LED was to indicate charging when the device is off. I would have to plug into a low power (computer) USB port for an hour or so, then unplugging and plugging back in would trigger the LED and the device off charging animation. At that point using the factory charger would work again. The drain time was abysmal at this point [emoji6]

the performance actually is not bad. infact its smooth , but when the battery falls below 50 or 40% the phone will start giving me random shutdown.
but today i did something I would call extensive draining. after the bootloader logs reset, i let it drain to 0 then it shutdown, then i again reset the bootloader logs then it started and show me 10% battery so i let it drain again , then again same process repeated it showed me 8% twice. then after 4 times of doing this draining process i finally got it to 0% where it refused start and show me empty battery icon. then i connected the charger for 1 minute then started the phone and it showed me 1% and charging. and from that point i let it charge full 100%. now iam testing it. if it still shuts down then my battery is dying.
and why replacement batteries have 3025mah ? whereas the one that came inside the phone has 3220mah.

The shutdowns at or near 40-50% I feel are early warning signs. I totally understand why you did it, I would have done the same, but charging from full dead to fully charged is actually harder on the battery. It's ideal to charge only a percentage at a time. That said, I charge when it's convenient, without regard for care for the battery. I often leave the phone on a low current charger such as when I'm traveling. I got about 2.5 years on the original battery and bought a spare last month figuring it'll need to be replaced before I replaced the phone.
My only guess why there is a variance in replacement battery capacity is that the ability to be used as a replacement (size/wiring) is the criteria rather than the capacity.
