First off, thanks Ohmster. I've been lurking on this forum following this thread and the one in the development section since I started fooling around with nightlies. Anyway I just wanted to thank you for your involvement in these parts.

I think I didn't explain the battery issues too well. For the most part the battery life is good and I try to be careful (Bluetooth off unless I'm using it, GPS on power saving unless I need it, phone on airplane mode when I'm on the subway). The issue is that when I reach the 60%s in charge, eventually the battery just drops to 50% all of a sudden. Next time it happens I'll save a screenshot of the details in the battery settings. Anyway it looks like a complete vertical drop instead of a continuous discharge. This behavior also happens when charged to around 30%s and drops to 20%. This is over many nightlies (and monthly snapshots), after wiping Dalvik, Cache, the whole ROM slot on SafeStrap, deleting and making a new slot.

Again, thanks for the recommendation for Battery Doctor and the article. I've tried the app before (saw you mention it once) but I'll give it another go. I'm amazed how you manage to stay on top of these threads.

Two things, 'Battery Calibration' app is designed to clear the battery stats saved in the phone and could help minimize 'jumps' after a couple of charge/discharge cycles; I've also seen devs state that our phone's hardware was designed for 10% battery monitoring, and the 1% 'hack' we're used to is not reliable/accurate. Just to add to the confusion, compare battery levels as you boot between stock ROM, SafeStrap and CM11...

Reminds me of the story of the man who wore two watches... he never knew WHAT time it was!

Thanks. That bit about our phones being made to detect the charge in 10% increments and not 1% makes sense, I just would've guessed the sudden drops would have been to the next lowest lowest interval of 10% (so something from the 60%s to 60%, not 50%). Maybe there's some 'drift' in the readings compared to the true value.

I wasn't trying to save the 'best' for last, but if you can duplicate that drop across more than one ROM even after clearing battery stats, that is also a symptom of a Li-ion battery nearing the end of it's service life. [emoji20]

Very good, Brian. Yes, the phones do measure in 10% increments. The battery stats are cleared every time you put the phone on charge. I learned this with wakelock, all the important stats I wanted to see were gone when I put the phone on charge and that is how it works. I have been in consumer electronics repair all of my life. Lithium Ion batteries are very good, last a long time, do not get the memory effect, but they do die. And like Brian said, they can drop huge chunks of charge when they do.

The reason I suggested Battery Doctor and WakeLock is because you would get some stats as to what was using power and when. You get to see the discharge cycle and either find the culprit or identify a battery on it's way out.

Brian is very good at problem solving and he is good at explaining it. So far as staying on top of things in the thread, well, that is a shared responsibility and good members take turns covering the group. When I am not available, Brian will step up. When others have obscure problems like APN issues, you will see chinkster or my2 jump in to help as they have a lot of experience with issues like this that I have never seen. It is a coop group where we all take care of each others needs and you can be a part of it too if you want. If you see someone with an issue that you are familiar with, step up and give some advice. This takes the load off other senior members to help others. We have a good, working thread here.

Brian, you know your emoticons from TapaTalk do not work in the thread on a PC? I see [emoji20] instead of the actual emoticon itself. You can try some of the basic emoticons by text if you want such as a a colon followed by an open parenthesis to show a smile. It works and all the rest have these same text foundations. So the smilie with text only characters looks like this:

A thumbs up is a "colon, good, colon" to create like this:

You get the idea. Thanks for helping out Brian. This is an excellent way to show insanespecialist exactly how this thread and the cooperation between members really works. You have done an excellent job, Bri. Thanks buddy!

Hmmm. "JakeDHS07 and Ohmster's CyanogenMod Q&A Thread" doesn't sound possible anymore. But when people like you and you yourself appear to help out those new guys with questions, well maybe we can keep Shaun's legend alive that way. What a glorious tribute that would be. You really rock, Mr. Hughes. Did you know that?

Thanks for the advice - I'll look into more tomorrow after a good night's rest. Thus has been an issue for several months now so I'm guessing it's not a sign of imminent failure.

Anyway, Ohmster, I saw you asking about the call screen settings in the other thread. Asking flashing 7/29 I was looking around for them too. I think I got it. Goto "Phone" (the app), settings, then scroll down and you'll see a section called "Other Call Settings". The third setting from the top is "Incoming Call Screen Style". That has two options, "Classic" and "Fullscreen Caller Photo". Hope that helps.
