[MOD][XPOSED][2.3+] DisableCriticalBatteryShutdown - v1.0 [ABANDONED]

[zst123]

DisableCriticalBatteryShutdown
(for Xposed Framework)

What?
Disables the Auto-Shutdown when Android detects a critical battery level


Why?
This is to prevent the auto-shutdown when you have 1% left of battery. It is useful for calibrating your battery by draining it completely, using Chinese Branded Batteries with terrible battery percentage detection or even lengthen the life of a phone with non-removable battery with terrible calibration.

Compatiblility
Not working on 4.3+
Tested only on AOSP 2.3, 4.0, 4.1

This project is abandoned, I will not add support for any other ROMs.

The App has no interface. It only shows a notification for the attempted shutdown (shown in the attachments)

Disclaimer 1
I am not responsible for any damage to CPUs, SD cards, Internal Storages, or other failures that happened after your battery became flat and your phone abruptly dies.
By choosing to use this module, you are fully aware that this can cause damage to your phone especially when writing data to the SD Card or Internal Storage.

Disclaimer 2
Lithium-Ion batteries should not be drained everyday over a long period of time. Doing so WILL decrease the lifespan of your battery. Calibration may or may not be a placebo, however, it really depends on how you use and what type of battery you use. If it has no effect for you on the first "calibration", please do not continue to drain your battery everyday.

some questions from me:
1. if phone's battery goes '0' bar, will it shutdown automatically?
2. compatible with android 4.4.2 or not?

thanks in advance

1) No. Until your battery is completely dead
2) Yes, I haven't tested but it is compatible.
If it works, your phone will abruptly shutdown after receiving the "Blocked Shutdown X times"
If it doesn't work, you will see the shutdown dialog with the spinning wheel before your phone shuts down.

this might give an extra 5minutes juice, that's it?

Thanks for your explanation. So, Whats the side effect from this app to the battery life? not damage to the phone's battery, isn't?

Yea. Maybe more or less but long term usage will decrease your battery life. Only use it for calibration.

Thanks for your explanation. So, Whats the side effect from this app to the battery life? not damage to the phone's battery, isn't?

The side effect is allowing the battery to drain completely. Ususally used for calibration but if you use it everyday over a long period of time, it WILL decrease your battery life.

So, when did the right time to use it?

 

[iede]

Tried it with SGS4 I9500 Android 4.3
Doesn't work.

It's not compatible with 4.3 mate?

 

[killoid]

@zst123 gonna try it on my galaxy y duos stock GB 2.3.6.will post results later.

EDIT: it worked! thank you so much!

Lithium-Ion batteries are NOT meant to be drained. You WILL decrease the life of your battery (since it weakens the anode bars physically). Draining works for Ni-Mh batteries. Android calibrates your battery between 80 and 90% so if you have Lithium ion batteries, calibration is a placebo. Correct me if I'm wrong. :good:

Actually, if the battery metering chip (also known as the 'fuel gauge') is giving inaccurate results, calibration will make a world of difference. Here's an example - on my (generic Chinese) tablet, the meter often goes down quite slowly during usage, while voltage goes down normally (according to BMW). When the meter hits ~35%, the battery starts going down abruptly (~1%/second), until it gets to 0 and the tablet shuts down.

This doesn't mean at all that I have a flawed battery, since I am getting the same usage time as when I bought it (battery was flawed from the start? :silly: ) - the battery meter chip is simply inaccurate.

Thank you, OP, for this mod, it's gonna come in handy.

Sorry for my ignorance but what is the difference between this & removing the batterystats.bin system file?

Very clever question:laugh: Want to know that too

Removing battery stats is different. On a battery with a terrible calibration, it will not prevent Android from shutting down when it (wrongly) detects a low battery. This module disables the shutdown when you reach 1% and below. Long term usage of draining to 0% WILL lower your battery life. So use only for calibration

Thanks. I recently purchased an extended battery with twice the mAh as the stock battery but I am still getting roughly the same amount of time out of a full charge. I am hoping this will fix that. :good:

 

[ronald_loulan]

YES!!!
Looking for 1 of this for sometime...
Good job...

 

[Rimmir]

My phone seems to have wonky battery life, it will jump from 14 to 12 to 10 to 3 percent then shut down.

This should help immensely for calibration if it does work.

Will report back. Happy holidays ☺

Didn't seem to work for my Beanstalk 4.4.2 HTC One. I am 100% willing to beta test or provide any data if needed

(I installed and activated module, rebooted, let battery drain to 0 from 16, phone proceeded to shut off right away)
