I am getting strange battery life.. I'm running kp1 modem with andromeda and speed mod kernel, and my battery will not last me a day with light usage. (some xda browsing, tweetdeck, texting) I've deleted battery stats and fully discharged and then recharged and that is what these screen shots are from. Any ideas?

Well for what ever reason, a Kernel/Modem/ROM setup on one device might not have the same "Super Battery Sipper" effects on another.. It's all about trying out what works best for YOUR device.
So start playing with Kernel/Modem combo's unless you want to change your ROM.
Unfortunately there is no set science for some reason

If you're using an older version of speedmod, make sure the battery tweaks are enabled under the recovery menu.

I've tried everything, I've used jpy, jj4, and ji6 based roms, cognition, perception, andromeda, cezars... And I am using the most up to date kernel from hardcore. I'm using the kp1 modem for now but I've tried all the other modems and only jk4, jl2 and jk3 work well. I'm also using the lowest brightness setting and juice defender. I get about a day out of out with light usage..

Lite Rom v2. I use quick setting and turn off auto sync and mobile network when not needed. And add two hours to that time. I had a reboot and it took two hours off.

In theory, having a more "lightweight" ROM with less processes in the background should use less battery. But kernel and radio have as much (if not more) to do with battery life than just the "style" of ROM. In particular, if the radio you are on is not the optimal for your location, it may drain your battery much more than anything else. And there are so many other variables that determine battery life. Its best you do some trial and error on your own to figure out what ROM, kernel, radio gives you the best battery vs. performance vs. features for your own particular needs.

Insane battery drain

I am on Prometheus ROM with stock kernel. The battery drain is insane and it only happens when Wi-Fi is unable to turn off and gets stuck, any suggestions?

The only thing I have installed that relates to battery saving and wifi is wifi static which forces a static IP
@hugokaka which icon are you looking for specifically?

This can cause your problem. Wifi is trying to connect but can not by strange reason. I have this with different roms an kernels combinations. No cure till now.

That to me looks most likely some setting and ROM issue. Make a backup flash another ROM try how it goes but am pretty sure Any other ROM shouldn't drain this much. Don't want to judge any ROM or anything just trying to help.

What battery model is it? Some of the extended batteries going around are just regular cells in a fat case with shims, especially the cheaper ones.

Same 'problem' here

the same. I am curious why

I can't explain it technically, but its because the battery is being monitored while discharging at different rates.

The phone doesn't actually "know" the battery level, it only knows certain points, and the rest is interpolated based on previous usage. If the interpolation is off, then it is corrected at those bumps.

I think it increases the bigger the battery capacity is. When I was using a 7,000 mah extended battery on my old phone it would actually go back up a couple of %.

up!
