How do your results compare to just one battery? There are people getting 4hours screen on with one battery.

You should plasti dip those exposed wires or something. If one breaks off because of a cold solder and shorts out it could start a fire. At the very least put some electrical tape on it.

Good point...screen on time is not important as cpu max load. If your phone work ar max load it will die a lot quicker than screen on

Any update in your battery?

Would be possible to use a generic extended battery housing and swap out the battery's with Samsung ones?

nope. at least not with my Max power ones. i was going to try to use the same charging circuit board off the Max power batts but the samsung cells are bigger and dont fit inside the non-OEM case underneath the stickers.

however the battery door from my Max power batts does fit the phone with the modded Samsung 4200mAh if thats what your asking?

i actually haven't gone thru any full discharges other than the ones i posted due to a really busy work schedule. but i will update ASAP.

update:

25hrs off the charger. 3hrs screen time, played N64 emu for about 45min, poweramp for 2hrs, pandora for 1.5hrs, 30min of web browsing, 45 min of voice calls, etc...

all radios on except WiFi. been on 4G this whole time. no power saving, auto brightness.


still got 41% left.

need to figure out what "Media server" is and why its taken more power than my browser...

Sweet, thanks.

Currently @ 6% and over 7hrs screen time. Ill prob be able to squeeze 36hrs out of thisbattery with no compromise on my usage. On heavy use days (more web and screen time) I'd surly be able to get a full 16-18 hrs of use.

Ill post screen shots when i get down to 1-2%

i will but im pretty sure NFC is not working right now. ill have to do some crazy soldering tricks to get it working. worst part is that it all will be off theory. as i still cant find a schematic.

-------------------------

Update:

i had it down to 4% and then i had to use my GPS for a longer period of time than the batt would last so to avoid taking screen shots and rebooting during my trip i had to just put it on the charger. but here are the screen shots. im pretty happy with the results.

mind you i would not consider this "heavy use" for my normal day to day. but the idea is accomplished. i have a battery that can last me 1 full day now matter how hard i beat on it.

all radios on (except WiFi) always on 4G, no power saving, auto brightness.

5hrs of pandora

3hrs of PowerAmp

1hr of N64oid

7hrs screen time

45min voice calls

Wow this is crazy. I would love more details of how you did this. I'd seriously pay for a battery mod pack like this.
