Thanks for this update goes to Unknownforce @ PPCG!
Just thought I'd share this here...
First and Foremost. This is NOT supported by the Devs... NOR am I a
Dev... This is simply a modification of the code that generates the
zImage file. (specifically the file htc_battery_smem.c)
Secondly... This has ONLY been tested on MY OWN Sprint Touch Pro 2... I
cannot guarantee it will work on ANY other device including other
sprint tp2's.. I just know that it works on MY device... so I figured
I'd share it...
Thirdly... It's not dead accurate, it's using some of the calculations
from the raphael's battery calculations... I have been told by one of
the devs that the rhodium calculates battery life much differently, so
I will say that this isn't supposed to be a REAL fix, just a temporary
workaround.
OK, now that all that is out of the way... here's somewhat of a "fix"
for the Battery meter for the SPRINT CDMA TP2 RHODIUM (At least that's
all I've tested it on)
It's the same zImage as all the others with just a single modified
source file compiled in. So all you have to do is copy it over the
zImage file you currently have and run android like normal.
The zImage includes all zImage updates including the one from 5/29/10

6/4 UPDATE
As you may have noticed... when you plug your phone in the battery
meter jumps WAY up... well I have done a slight modification to the
code to have it show something a Little more accurate... (only slight
testing done)
Basically what I did was make it check to see if it's charging, if it
is, it does less of a calculation based on the mV reading...
It's not perfect, but it's much closer to accurate when charging now,
And what I did was make it so that it's a few percent HIGHER than the
actual reading, so hopefully (and I don't know for certain) it will
think it's at 100% when it's more like 95 ish then it will stop
charging the battery and it won't keep charging and possibly do
damage... as I said, I've only done some slight testing with this...
but I figured I'd post it and get some feedback... My next thing is to
figure out how to stabilize the battery meter so that it doesn't
fluctuate as much, As an example, the percentage should never go UP
when the phone is not charging, and it does... and also when you're
actually using the phone for something that's got a drain on the
battery, the percentage drops a lot because the mV reading drops when
it's under load, So I have to try to figure out how to add in some
calculation to incorporate current load so that it doesn't drop
dramatically when you're online or something...
But back to the fix at hand here... You'll notice that at first when
you plug it in, the % drops a bit, this is because the mV reading does
not increase immediately, give it a minute or so and you will notice it
start to climb back up as the mV reading increases. The inverse is also
the same, in that when you unplug it AFTER charging for a bit, the %
will spike for a bit, the mV reading will start to drop and it will
stabilize in a minute or so.
I also made the change apply to all devices (not just the rhodium) but
I don't know that it's a problem on other devices, but figured it
wouldn't hurt to add it as most people here are using the rhodium
anyways...
I will gladly share the code if anyone wants to take a peek.
Enjoy!
Use this
rootfs below instead. You will have to download it, rename it, and add
it manually to your andboot folder. Do not use the updater for roofts as the current one is
corrupt! I will update further when a fix has been pushed through.
