ICS ROMs and the battery charging issue, possible cause?

---

In the CleanROM ICS thread, Marine6680 posed an observation that I think bears looking into.

Please vote only if you are using an ICS ROM.

EDIT TO ADD***

Also please vote based on how your phone behaves while it is turned on. If you experience different behavior when the phone is off, please post that as a response.

END EDIT***

So it could be that these new 3.8v batteries (which are tweaked chemistry versions that have a slightly higher voltage than standard 3.7v) are not supported by the new kernel's charging controls. (which seems odd that it wouldn't) That is, if that is even controlled by the kernel and not hard wired into the mainboard.

So it may be an issue with the batteries... or not. If it only happens with the stock batteries then it will be harder to say for sure.

I've posed the question in both the CleanROM and Ineffabilis ICS threads, but figured I'd post here to try to get all ICS ROM users to see it.

So far, all responses in those 2 threads have been that people with charging issues all had 3.8v batteries and that people with no charging issues (myself included) had 3.7v batteries.

Please respond here with your findings. Just pull out your battery and look on the back, top line of text.

I'm not sure what can be done about it, but at least it would answer a question that seems to be annoying a lot of people across ALL ICS ROMs.

Great idea for the poll, but still wrong section. Should be posted in General.

Sorry. Can a mod please move?

I have the 3.7 battery and have had no issues with charging at all.

I have a 3.8 for about another 3 hours. I'm stopping by Verizon and getting a 3.7. I dare them to try to tell me no.

I have a 3.7 with no charging issues.

Well, my battery lasts like 2 hours since I put ICS on there but I can't tell if thats the usual terrible Rezound battery life or something wrong with my rom.

If I charge too 100% while it's turned off (since I have the 3.8v battery), I get great battery life on ICS. Yesterday I got around 16 hours with 4g on all day under normal use. On stock GB and the two GB roms I tested out, I was getting between 14 and 15 hours on average with 4g turned off.

If I try to charge with it turned on and experience the 87% ceiling, I get horrible battery life. 10 hours max, and the battery seems to discharge very quickly when I'm actually using it.

on my De-Sensed ICS Rom it doesn't charge up to 100% pretty much stops at around 98%~.. I have pretty amazing Battery life Could go an entire day with out hitting 20%, but then again I don;t have alot of apps

I have a 3.8v battery, running ICS, no charging problems, no battery life issues.... no nothing.


The ONLY strange issue I have, and I've had it since day one on GB, is that when i unplug my phone from the charger it will say either 99 or 100% on my battery widget, however if you wait a bit and then look at the battery stats chart later in the day, it shows that it began discharging from 93-94% rather than 99-100%. I simply assumed the battery scaling in software was slightly off from what the battery itself is reporting, but since it doesn't seem to be a problem at all I have just ignored it. The battery easily lasts all day with plenty of juice to spare for me.

That's normal if you're not bump-charging.
