I am going to try and not leave anything out here....
This first started while running Cyan 3.6.8.1 with 1.3 recovery, 26I radio and HardSPL. I was running the overclock widget and I stupidly set the high and low to 528. What this has to do with it, I dont know. Ever since my battery has been very bad and very wierd.
It will drain very quickly. (I have owned my G1 since November so I am aware how short the battery normally lasts) Re Flashed, wiped, tried 1.4 recovery, tried JF's ROMS, older stable Cyan's ROM (3.4.something). During this time I could not hit 100% battery, even after a 15 hour charge. At this point I bought a new stock battery and a 2300mah battery. Even though the 2300 seemed to last a little longer, it still dies within hours.
I got it up to 99% and deleted the batterystats.bin file through the terminal and still nothing. Also, I let the battery run down until the phone shut off a couple times durring this whole ordeal.
It seemed like I had no other choice, but to unroot. I then got the OTA to CRC1. At this point The battery wasn't dropping as quickly and I actually hit 100%!!!!!! Things seemed to be going my way. Over the next day it was great. Then once again it turned for the worst. I once again couldn't hit 100% and now it seems to stop charging at random points... once at 98% then 71% then 63% then in the 70's again.... You get the point. I am using the BatteryLife widget and while watching the extended info totally freaks me out. While I was not charging I watched to mV go from 3808 and 58% battery to 3816 and 52% battery! How can the mV's go up with the phone unplugged?!?! How can the % go down with the mV's going up?!?!?!
Any ideas????? Anything would be greatly appreciated.
Thanks
I think mV is the drain on the battery or the actual volts in the battery. For example, 4000mV may be 4.0V, however in Cyan v3.97 there's a feature in Spare Parts under Battery Info that tells you your battery health.
For example, mine is currently:
State: Charging (AC)
Bat. Level: 54
Battery Scale: 100 <-- Dunno what this is.
Battery Health: Good
Battery Voltage: 4128mV
Battery Temp: 33.3*C
Batt. Tech: Li-Ion
If you get "Battery Health: Bad" well, replace it. Also, with the battery not charging 100%, it could be getting too hot. Maybe pop it in front of a fan or something?
the battery scale is just the scale it uses to determine the battery level. scale of 0 to 100 battery level of 0% to 100%. i do not know why your battery level is depleting at that rate. clocking it to 528/528 will drain battery faster, and when it freezes at a percent try rebooting the phone and see if that corrects what the stats are displaying for the charging percent. it has been documented in other threads that the battery will freeze at a percent but fix its readings upon a reboot
I dont even need to reboot it to "unfreeze" the percent. Just unplug it for 5 minutes and plug it back in. I know clocking to 528/528 will drain it faster, but that was long ago as I am now unrooted trying to fix this. Also, when I say fast, I mean fast. Sometimes it will go from 99% to 50% in about 20 minutes with the phone at idle.
The battery drops quickly to 5 %. Often skips levels, such as drops directly from 40 to 20.
If I reboot, the percentage often increases by several levels.
When it has reached 5 %, it stays there for a long time before shutting itself down.
I plug the charger in and it will say 5 % but already after 20-45 min it will say maybe 50 %.
Then I unplug and start the phone, and then it might say 70 % instead of 50.
I use battery monitor widget and have some interesting lines of info from its history attached as a screen shot.
At the top of the screen shot, I started running wifi hotspot (the temperature drops because I placed the phone in the refridgerator so that it wouldn't get so hot).
Notice how it drops from 50 % to 15 % in 10 minutes.
Notice how it then stays at 5 % for more than 90 minutes before shutting itself down.
Notice how it recharges quite quickly, 20 % almost immediately after plugging in and starting up the phone.
I have tried a new battery and I think I even got the entire phone replaced (warranty), but this still happens.
I've tried various calibration techniques and ROMs...
Does this happen to anyone else and does anyone know of a calibration technique that actually helps for this?
Its realy strange u can try to delate date/system/baterystats.bin maybe that help... I got no clue why u phone see diferent voltage every time. Did u change u system recently?

Change the system? I flashed Telus Lite a week or two ago. You're right, I hadn't thought about the voltage going up and down
I have tried deleting that file
Would someone with a Milestone with alright battery life, please upload their batterystats.bin here, so I can try replacing mine with it?
I have this same issue with the battery I bought in amazon. Out just takes 1h to see the high percentage battery drops. The battery calibration does not work.
This Issue not happens with the battery that came with the phone.

I have the original battery and a battery from ebay, the phone acts the same way with both though.
Would really appreciate it if someone could upload their batterystats.bin
Edit: This is probably gonna need a new thread.
Hi
My Nexus One just completed one year by this july.
And my problem is that My battery switches OFF at 23% battery.
That is, when it reaches around 23% it suddenly show 0% and switches off.
similarly when i charge the battery after around 75+ % it suddenly jumps to 100% percent and says charging completed.
I tried manually deleting the battery stats file.
I tried the Battery Calibration tool.
I tried charging the mobile to 100% as soon as its starts to shut down.
But still the same issue.
Is there a way to calibrate it or do i need to buy a new one ?
My rom : OxygeN1mod
I am getting around 6 to 8 hours if i use Gprs or wifi.
Another query :
in ebay.in 3200mAH battery is 9800 INR which is too high for me ( i bought my mobile for 14000 INR)
1400mAH battery is 2400 INR.
So is it better to buy a spare 14oomAH battery or a 3200 Battery ?
Please help me.
THanks in advance
Any one , please help
Tha'ts not normal if it's shut down at 25% ! ! !
Normally at 10%
Should buy à New One
If you don't care about the design of your n1. I suggest you the 3200 one

I heard that you can't fully charge the battery while the phone is running, it has too leave room since the battery is in use at the same time it's charging so it wont overcharge and ruin the battery.
So I was recommended to shut the phone off once in a while to charge the phone to full 100%.
Mine is now starting to die at around 20% but when new it died around 10%, newer lower.
But then again the battery could just be going bad.

Install de battery calibrator (for nexus one) search in the google play
Verify the field "battery age" and set to 100%
Reboot and give a full charge
Drain normaly the battery, and look the percentage of the shutdown
If your phone shutdown on the 15%, set the battery age to 85% (100%-15%)
If dont work try:

Hello, X510 just arrived in my country, Morocco
Pretty nice phone , well at least not bad (price about 84 USD).
but I've noticed that the battery is not calibrated , It shows 100% but when I restart the device, then it shows 80 or 70.
and then the battery goes to 0% in less than 2 hours.
some say that infinix fix that bug in updates, but my phone is up to date 23/01/2016 .
anyone have the same Probleme, or solution ?

Try draining the battery to zero, keep it turned off, and fully charge to 100%. Turn the phone on and see if that helps.
The Battery Doctor app from Playstore can also help clear and reset your battery stats. Be forewarned its a huge file and uses alot of RAM. I disabled it after using it.
You may also have a lot of apps running or running in the background that will drain your battery dry (e.g. Facebook, Internet, What'sApp, various games, etc.). Greenify is another app that will help close those pesky Apps running in the background).

I am having this issue as well. It happens when using powerbank and non-infinix charger (the percentage raised up from 30% to 91%).
My batt was at 36% and when charging under powered with pb, instead of increasing batt %, it was decreasing LoL. Then it suddenly showed 91% when powered off while charginf by pb.
H, since I updated from miui 10 to miui 11 and even now that I have miui 12 I have noticed that the battery doesn't last as long as before. I state that since I purchased the phone (July 2019) I have always charged the battery in the best way trying to never go below 20% and trying not to go beyond 80% so I don't think a battery can lose more than 30% of its real capacity in less than a year of life. Starting to investigate I found that the battery does not charge at its real capacity i.e. 3300 mAh but at around 2200/2300 mAh. To verify all this I have carried out several tests and the easiest way to verify it is to look at the battery characteristics through the AIDA64 app (screenshot below). From these tests it seems that the device limits the real battery capacity by not allowing it to be charged to its maximum capacity. A reply to what I wrote can be found by looking at some system files that are located in /sys/class/power_supply/battery. In particular, looking at the file called charge_full (screenshot below) you can see how the value of the file is much lower than the real battery capacity. I hope someone more competent than I can understand how to solve this hateful problem and I also invite you to check the value to try to better understand the cause of this problem.
I'm using miuimix 12.0.2 stable and the capacity is not 3300, either.

And sorry i don't know how to post a picture, mine is 2943.
I know that batteries won't be forever and are always decreasing during the year but I think Xiaomi do a good job. I have some devices from 4 years ago and they reduced their batteries just a little. In the case of Mi 9 I have it since March 2019 and my battery still being the same. I charge it from 10-25% to 100% just some times I charge it until 80-90%, maybe every month I let it to 0% I wait for a while and charge it again to 100%.

From the photo you posted it doesn't seem that your battery is fully charged .. we have done other research and we have discovered that most likely Xiaomi has inserted in the kernel a sort of programmed obsolescence on the battery.
Can you disclose some of the research you done on the kernel it seems interesting. I have checked with Aida64 my battery before and it never charges to 3300 even if you leave the phone plugged in the value will keep increasing but once you plug it out it drops...still getting about 5 hrs sot so not bad...I wonder if you change that value in the full charger screen you posted what will happen?
"From these tests it seems that the device limits the real battery capacity by not allowing it to be charged to its maximum capacity. "
Actually it's better for battery life longterm to keep the device in the middle - never 0, never 100
I've certainly lost no battery life in the year + I've had the Mi 9
You are doing a good job of using the phone in the 20 to 80% range. But do you charge it at the lowest possible temperature? Temperature is a battery's worst enemy. Wireless charging is a joke. It's a glued heater in the battery.
I for instance, almost all the times charge it in front a mini fan. With this I can charge it 5ºC below normal temp charge.
And like @cezikos said, use quickcharge only on emergencies. Use at max a 1.5Amps charger. Quick charge is a marketing thing. The chemistry of the batteries are almost the same in this 10 years.
Mi mi9 have one year and the battery is 100%.
The important thing that you should precise is a type of charger that you are using. Do you use Quick Charge? If Yes, then battery capacity will be dramatically degrated. I use 5V 0.5-1.5A charger, it depends how fast I need to charge the Phone.
The next thing is a battery temperature, not Only while charging the Phone but also when you are using it. I`m using CPU Monitor and it's overlay to see the battery temp, you can also configure alerts when battery is starting to overheat.
Heavy Gaming decreases the life of the battery, there are a lot of variables that you have to cobsider, not only "programmed obsolescence"
I had the same problem. Hopefully the battery could make 3 hours of screen, the strange thing was that suddenly it began to last very little, and I was with that problem for a couple of weeks, so I decided to calibrate the battery hoping to have some results and now the battery lasted again approximately 7 hours of screen. Try to make the battery run out from 100% to 0%. The system will not let you start because it calculates that it has no battery, so what I did was leave it in recovery mode and with the screen always active, until it turns off completely, then with a 5V 1A charger. With the phone turned off, charge it until it reaches 100%. I did it three times and the battery was back to the way it was before. You could try to do the same and I hope you can solve that problem.
Sorry for bad English
I tested, I put the phone to play videos until it turned off. In 1% I cleared battery stats.
Then plugged the charger and entered the TWRP and unplugged. Put the backlight to maximum, and the phone stayed on more than an hour!
Then I plugged the charger 1.5A and let it charge to max.
It worked, now the phone has a steady discharge, not discharge 100% to 80 in an hour.
I will do this procedure from time to time. not the best for the battery, but is needed in mi9...
It's an absurd that this problem exists in 2020, my galaxy S2 don't have such harsh problems with something so simple and basic like battery management!
Battery on my Mi9 (mildly used in one year) lost 500 mAh.
Confirmed, with this trick, in doing it ONE time, I have the phone running well again, more than 8h screen on.
0.5 discharge in sleep.

Thanks! I just don't know how to clean the battery status...
You will need root.
Then are several apps that can do it. Like l speed or adiutor.
And now again confirming, in one month the phone is completely lost regarding battery again, just 3h SOT from 80 to 20. There's some pretty **** up code regarding battery in xiaomi android.
I have no problems at all using it since release.
newest xiaomi eu.
I also have problems with battery drain...
Hello guys, just want to share with you a little trick that just helped me get better SoT. First of all, I just want to mention that I'm on the newest xiaomi.eu rom (20.8.13) and that AccuBattery is showing that my battery is at 2500mAh estimated capacity. (That might be different in reality, because it's only after one charging, so don't believe it that much). Lately I noticed a significant drain while the phone was idle (screen turned off). It was draining like 1-2% every hour and I could barely get over 5h SoT. So I investigated a little bit, and found a solution on reddit. The thing was that I had many apps on autostart. If you want to check them and turn it off then open Settings > type 'autostart' in the search bar > open it > 3 dots > show system apps > turn off every unnecessary app that you think don't need that option. I turned off every app, except: Gmail, GPay, Google Photos, Clock, Calendar, Bank app, Weather app and the app called 'safety system addon' - it might be called different because I'm not on english language on my phone. I left them on just in case to have notifications/synchronization, though i don't know if it's necessary. After that there was almost 0% idle drain over the day. Now I'm on 5h4m SoT and still have 25% of battery left. The result might be even better, cause I did this trick just today while my phone was on 90-85%.
Give it guys a try, hope it will improve your daily experience with Mi 9.
P.S. Let me know guys If I could turn off the before mentioned apps and still get notifications and sync from them.
Mine reports 2800mah, debloated with Szaki tool all autostart apps disabled also did factory reset after miui12 update.
Really sad how bad miui12 has turned for me. Im having way worse battery life compared to miui11 the idle is mostly the same its just the battery doesn't last as it used to last with miui11.

I can confirm this. AIDA64 said my battery was at 2550mah capacity when fully charged. I followed this procedure and now after being fully charged, it says 3125 mah, which is much better.
I'm curious about the screen on time now. Me happy. Thanks!
