DCD 3.1.2 battery and backlight issues.

[Cycomachead]

For whatever reason my battery life is only being reported in 10% increments. Anyone have any idea as to why? AFAIK, it hasn't been removed, right? Searching didn't turn up anything.

Also my battery life seems shorter, but it could be the battery.

The backlight issue has been there for a while and I've tracked it down to installing HTCHome (the one from this forum) How can I fix this? Uninstalling seems to fix it and i've tried to save and recopy the exe and dll for the backlight, but recopying didn't work.

I haven't installed much recently except for the Diamond large start menu and Adobe 2.5 from the diamond. Further back I installed the 2.0 task manager with big buttons. But I don't know how long it hasn't been working right.
I'm using DCD 3.1.2 and radio 3.35 on an xv6800.

10% increments are the WM6 default. A special battery.dll was created [I believe by no2chem] and integrated in the previous DCD ROMs.. but for some reason it was pulled.

Battery life with 3.1.2 has been fine. It's your battery. Be sure to keep it well charged*, never let it dip below 30%! If you notice it's wearing thin -edit- it may simply be the indicator reading your battery incorrectly, in which case a full discharge / recharge will allow the phone to more accurately read the charge level. Regardless, your battery is under warranty and I suggest taking advantage of that and starting fresh with a strong initial charge.

Could you be more specific about this backlight issue?

*battery is optimally stored [for longest life] around 40% capacity.

The 1% battery dll was not added to 3.1.2 by accident. It's fixed in the next release. In the mean time, you can manually add it to the 3.1.2 kitchen by going into the 3.0.4 kitchen's OEM\OEMDrivers folder and copying the battery.dll and battdrvr.dll folders to 3.1.2 kitchen's OEM\OEMDrivers folder overwriting the ones in there.

Battery life with 3.1.2 has been fine. It's your battery. Be sure to keep it well charged, never let it dip below 30%! If you notice it's wearing thin you can try a deep cycle [24-48 hrs] with the phone OFF. Regardless, your battery is under warranty and I suggest taking advantage of that and starting fresh with a 24-48 hr initial deep charge.

I must comment on this with my questions because there are so many theories going around on what the proper way to handle this is...

first question.. you say don't let it go below 30%??? I thought it was GOOD to have it drained down to nothing every once in a while then doing a full charge?

second question.. DEEP charge? 24-48hours? seriously? I know it's good to always start with a full charge on the battery but does it really matter going beyond the full mark (a few hours I think?)...

Reason I'm really curious about this is because I just had VZW send me a new battery but I haven't unpacked it yet because I wanted to make sure I had the time to give it a good initial charge (over night). I'm not so sure I can go 24-48hrs without my phone but if it really makes a difference I might consider it?

I've noticed on my phone once it hit's 30% itll drop to 0% fast and i cannot use my phone for a couple hours because it'll take forever to hit 5% to turn the radio on

Well, since you took me up on it I am doing some academic research on the mechanisms Li-ion batteries use..


I do work in a cellphone store, and had the following experience with my battery:

First battery, charging method was improper and under regular use lasted no more than 7 hrs resulting in multiple charges per day.

Replacement battery came in, and underwent a lengthy initial charge because I had a second titan handy. 48 hrs.


I was amazed to find my battery life at around 3 days regular use.

I kept my phone charge above 30-40%, charging _regularly_ [once all night, with occasional top-ups during the day] and find the capacity has not changed.


Take from that what you will. Certainly, the length of time I charged my battery initially was probably not strictly necessary, but.. I'll do some more research and report back.

FYI, the majority of people with dead batteries who walk into my store are typically under the impression the batteries need to be near-fully [or fully? which is it, huh?] drained before recharge.

Which is _incorrect_ as it is only NiCad & Nickel Metal-Hydride batteries that suffered the memory effect.

It is worth mention that my first battery was often dying, which only seemed to exacerbate the issue.

Most make the mistake of running it down because previous generations of batteries worked that way. I have a dock that I got months ago (can't remember from where, but you can find it on the forums) that charges the device and a spare battery in a 2nd slot at the same time. That gets around the issue of not having your phone while the battery charges.

I completely screwed up. I was messing with the battery.dll file and ended up witout any battery monitoring whatsoever, and I'm not sure if the battery is even charging.

I restored my most recent backup (Sprite) and the battery is still "no status"

I took the battery out and reset, no luck.

I tried to flash a new rom, and I get [error 220] "battery less than 50% ...."

I know that the battery is at least 80%, so I figured that the battery problem is not letting the RUU run.

Is there a way to bypass the RUU error's,
I just yesterday lost my spare SDcard that I used for flashing. So that's out.

The only card I have is an SDHC (4GB)

anyone have any suggestions???

My ignorance is once again confirmed. a simple hard reset fixed the trick.

It's a simple copy/paste. You copy the 2 folders out of 3.0.4 OEM\OEMDrivers and paste them into 3.1.2 OEM\OEMDrivers overwriting the current ones in there. Then you just cook your rom like usual and flash.

Jefferson - To bypass the RUU error - Put your phone in bootloader mode (POWER + CAMERA + RESET) Tricolor screen. Now plug the phone into the PC and run the RUU. It should run fine.....

GC - The RUU won't run with the phone already booted into windows cuz it tries to read the battery level and can't....

Oh right...it's been so damn long since I've flashed with an RUU I forgot it's dumb like that and needs 50% battery. :D

I guess the part about having to "deep charge" for 24-48hrs is not accurate...

http://www.batteryuniversity.com/partone-12.htm
Lithium-ion is a very clean system and does not need priming as nickel-based batteries do. The 1st charge is no different to the 5th or the 50th charge. Stickers instructing to charge the battery for 8 hours or more for the first time may be a leftover from the nickel battery days.

[Cycomachead]

GC and other's thanks for the replies! I've been busy with school (NOW I"M DONE, for a while!!!) and then on vacation.

My titan seems to be having charging issues so it's going to verizon to be checked out.

Any ideas about HTCHome?

[Cycomachead]

Oh yeah, the other thing:

WinMo couldn't be more annoying with it's battery warnings!!!! I swear half my low battery time is spent trying to shut em up.
