I am facing a peculiar problem since last few months.
On every Restart of the phone, the battery goes down by atleast 8-10% sometimes as much as by 15-20%. But this is not real drainage as on the reduced percentage the phone stays for long as it would have taken to drain in real usage.
I can't recollect from exactly when this happened but its not less than four five months. In the meantime I have changed many ROMs, calibrated battery with "Battery Calibrator" many a times, deleted batterystats from CWM when the position seemed to improve a bit. But after two or three restarts the same problem comes back. I am now on Mini CM7 ROM latest version by nAa.
I think its a calibration problem or is it time to change the battery?
Any similar eperience / opinion on this / help to rectify this. BTW I searched / googled for this topic but not found any. In fact I found a thread in some other forum for some other device where battery increases by 10% on every restart (Great thing is't it?)
Expecting some positive reply

Try to clean battery history (xRecovery/CWM -> Advanced Settings -> Clean Batery History) or use Battery Calibrator, found for free on market. The app has the instructions.
Either that or you could use a root explorer to delete the batterystats.bin file in data - system
Try to fully charge the phone first though then delete the batterystats file then unplug and let the phone fully discharge the battery, this should totally refresh the battery statistics that the phone reads

Thanks to both of you . I have tried similar solution. Still then I will try them again.
ok i have a x10 mini with mini cm 2.2.1 and nAa v14 kernel
if i restart i gain 10-15% more battery
it seems that if i charge it from usb i get better readings but if i use the house charger ( a iphone charger ) it charges quicker but battery stats are way off
did everything wipe battery stats , delete batterystats.bin , charge on or off etc
has anyone come across the Razr Battery self discharging? I noticed that recently the phone would run out of battery really quickly, charge very slowly and on top of that the battery will drain even while the phone is off.
Is this a phone motherboard problem or a bad battery?
My RAZR had been doing this even with smart actions on. I used to pull up to work with at least 90% battery n when I got off 12 hours later it would drop to 80% or so. Now I go to work and when I get off its at 50% or less. *note* during the 12 hours I'm not using the phone at all.

sounds like you got a "runaway" program or your somewhere with real sketchy (in and out) signal. check out your battery usage and see whats using the most battery (apps running in background using data networks suck power real quick), and in that click cell standby and see what the percentange of "time without signal" is.
Also, if you don't do it regularly (at least once every 2 weeks) power your phone off all the way and then back, i usually do it right before I plug it up to charge, kinda like what you gotta do with windows XP to keep it from slowing down. I say this because I'm fairly confident that most people don't ever shut there smart phone off unless the batter dies on them, but like xp this copy of gingerbread seems to slow down if run to long without a reboot.
it can't be a runaway program
1. the phone is turned off yet the battery drains.
2. The phone is a fresh install of the latest Verizon ICS leak
Is your phone rooted? if yes, is it rooted with the boot.img replace method?
if yes to both, then you replaced the boot.img after root, with a wrong boot.img...
to solve, create a folder and copy the boot.img from your fastboot package of the leak you installed, or find it form the ota.....
the create a txt file with the followinf command and save it with .bat extension.... then, run the .bat....
command :
adb reboot bootloader
fastboot flash boot boot.img
fastboot reboot
its possible I'm not entirely sure. I did do something with the bootloaders as I flashed 209 ICS leak with the UNSTUCK ics thing
Also, have you used a lapdock or hd dock? I had used them before with no problem, but this week if I use the lapdock it starts an application called evbridge which kills the battery. Worse, it shows up in battery usage but not in running applications or ES File Explorer task killer, so the only way to stop it is to power off after undocking.
Hello Im new here and to Android itself.
I know that there is a lot of similar threats about this but I havent found neither a solution that works nor the description of the problems in such disscusion that describes my situation exactly; MY BATTERY DRAINS WAY TO MUCH WHEN IN USE so here it is.
I flashed to generic GB, to get rid of the bloatware of my carrier (Telcel); then when available to generic ( i think it was Swiss) ICS 4.04 and then to the next compilation 6.1.A.2.45, I didnt notice much difference then.
But then I rooted it (like 4 days ago or little more) using a script that I found here only asked me plug my phone, restore the file it put in "Back up and restore" and then reboot,
My CPU SETTINGS are:
1512 max 648 min screen on.
468 max 384 min screen off
At 1st even seemed that my battery extended from 8 to 10 hrs average but then I noticed that my phones was dying rather quickl; I though it was the Nova Launcher, but after stop using it still my battery si draining i repaired with Sony SUS to stock ROM and re-rooted using the same method, but i restore my apps and setting with Titanium..
The thing is that if I do not do anything on the phone it seems to last but the minute I turn on the screen (which is at less than 40% of brightness) it start consuming power at 16-21 % per hour or more, sometimes it goes up to 40% and even 500% strange is that Android System it consuming 33% to 51% this morning permantely or so it says settings.
It is normal that the phone consum3 10% of its battery by having the the screen on for a couple of minutes?
I have tried Watchdog, GSbattery AutoRun manege and I dont find the culprit
I attached the screenshots, along with some of the app "Battery drain"
Thanks in advance
I've had my P900 for probably 5 years of heavy use.
The back of it has always got quite hot. Last couple of months I've started thinking it might be time to get a new battery, as battery life was getting quite poor. After reading through the old threads in here about battery problems actually being caused by the connector I decided to open it and have a look. I disconnected the battery, then pushed the connector firmly back into place.
The battery life is now about as good as it was a couple of years ago, and the area of the back that was getting hot is now not really any warmer than the rest of the back. I can only imagine how good the battery life would've been if I'd done this years ago when I got it nearly new.
I'd recommend anyone to try this first if your battery life is deteriorating, or if the device is getting hot. The difference is remarkable.
... is not a big effort but unfortunately I dare to doubt that this problem occurs more often ... I also use my tablet extremely. Actually 24/7 and I often push it to the limit. Furthermore, it has fallen down more than 2-3 times. But nothing has ever slipped. In addition, there are mostly plug, click and screw connections installed inside
If the battery is not broken, the most efficient way, I think, is to save only the app settings of the most urgently and needed apps, download an app that finds empty folders and files on your device, search manually the internal storage folders and find out what is what, delete what you don't need anymore, search manually your folders for files what you want to keep and save it together with the App settings externally.
After that make a factory reset, install the apps and paste the wished folders from external to internal storage again ...
At least for me this is often the only possibility to get more battery life back. ---- [ without Root permission or Flash ]
I on my xiaomi mi9 I installed the battery increased by 4000mha, I changed the kernel values with a file manager by making the phone read the same battery capacity and I do six hours of display on! To do this you must have root permissions with any custom rom (does not work with miui!) and buy 4000mha battery ...
the path to take with franco kernel manager is:
/sys/class/power_supply/bms/charge_full"
/sys/class/power_supply/battery/charge_ful
Through a file manager, that is the path to follow to edit the file. After doing the procedure you can go back to Miui with the kernel value unchanged at 4000mha ... fantastic isn't it?
where did you buy this enlarged batery? give me a link please
Hello, unfortunately I have a problem. The changes I make through FKM are not saved. They go back to their previous values. The change by the regular manager also failed. Anyone able to help me? Thanks!
All increased batteries are fake. I have bought a 7000mAh one one taobao (just to try) and it is still showing 3300. Writing a bad comment to the seller and got harassed on the phone like crazy until I agreed to erase my comment. On the positive side the battery is running ok as a 3300mAh and the seller just gave my money back!
Your 7000 mAh battery is obviously fake, who would've thought

Do you really think you can have a bigger battery capacity without having a bigger battery in size? I really doubt. The Mi9 pro has a 4000mAh battery and is 1mm thicker than normal Mi9. There are lots of different battery size on Taobao, from the original 3300mAh to 7000. Honestly do your battery really last longer after a full charge?

Of course you can! I myself bought a battery with a declared capacity of 4000mAh. After checking it has 3943mAh. So everything is fine. The battery, being in the phone now, I have to charge a maximum of 3300mAh, because that's what is set in the settings. If you want to be cheated, they will always cheat you ...

No, but I've already told you in another thread were you posted your claims that the battery (Lehehe 4000/4200 mAh) I've replaced is slightly thicker than the original battery.

Yes, noticeably. Standby deep sleep time, SOT, amount of charge left at the end of the day, power throughout the weekend with less usage, power while using GCam... Everything improved. Checking with AIDA64, my old battery had about 2700 mAh charge left. The new one still has slightly below 4000 mAh after almost 8 months of usage. But I'm not the only one, every single user who swapped to this battery is giving the same feedback (2 friends and multiple other users on telegram groups).
-> you need to manually adjust the "charge_full" value once after the swap (root needed)
edit: to give more info on this, this isn't a fixed value, the system itself manages it and it will change by itself with time depending on the calculated / measured charge to give the estimated mAh capacity left. Don't mistake it for the "charge_full_design" value, which is permantently fixed to 3300 mAh (what's being reported to HW info apps which don't show the above value)
-> you need to charge longer after it reaches 100%, AIDA64 is a good indicator, as it will show you when its charging and when it's really fully charged, it takes at least 30min longer after showing 100% in the system
-> you obviously got fooled with your 7K battery, "do you really think you can have a bigger battery capacity without having a bigger battery in size?"

Sure if you change your old battery with a new one you will have improvement! but ok, maybe I can be wrong
Concerning being fooled it's a yes and no. I knew it would be fake so I didn't expect the battery to perform as a 7000mAh. As the comments were good I just had a try.

Unfortunately, I have a problem with that. After changing the values to what I want, they go back to their original values. What program are you using to edit them? I currently have Android 12 and I am wondering if this is the cause of my problems.

You only have to edit one file:
root/sys/class/power_supply/bms/charge_full
Make sure you are in the BMS folder.
Root is needed. I use Solid Explorer to open the folder and edit the file.
Currently running Pixel Experience 12 and I can still edit and save it fine.

I do literally the same ... Unfortunately, I get the message: Failed to copy the file from (path) to (path). I tried Total Commander, it didn't work either.

It looks like the App isn't opening the file right in the folder, but caching it to another folder, editing, then wants to save it back which fails.

Exactly! However, Total Commander it communicates that there is no place. I do not understand this...
Do you really think the manufacturer didn't use the largest battery possible?
If there's any additional space it's likely there for an important reason. The batteries are designed for reliability and safety. There's no wasted space.
A fully charged Li internal short caused meltdown will destroy the phone... collateral damage can be expected if this happens.
Hi, what particular kernel and ROM can I use this on? I saw geekerwan changing the sys/class/power_supply/bms/charge_full value by using a script on what I think is a stock MIUI ROM but I couldn't do the same on mine. Doing so using root explorer reverts the value back

Hi, yes I was able to solve this problem but the solution is a bit more complex than I expected. Check my guide on it. I made it work on my raphael. Here's a link to a thread I made:
Making a multi-battery setup on your Mi 9T/K20/Pro, or any other Xiaomi Device
Hello everyone! Some time ago, I watched a video by Geekerwan on making a DIY Gaming Phone and I figured why not try it on my Mi 9T with a swapped K20 Pro motherboard. (More about the motherboard swap here). This could be done with other devices...
