I haven't tried going back to stock. It would bring back the baseband_xmm_power wakelocks.

Didn't measure temperature in the two tests, but in both cases the outer shell was noticeably warm to touch.

[I'll paste the full reports below.]

Wakeup counts. First line is online, second is offline/airplanemode.

"baseband_xmm_power" (): 1 h 7 m 52 s (4072 s) Cnt:(c/wc/ec)1599/0/0 14.0%

"baseband_xmm_power" (): 5 m 22 s (322 s) Cnt:(c/wc/ec)55/0/0 1.4%

Is 1h7m a lot? It shouldn't account for a 61% drop in battery?

"wlan_rx_wake" (): 24 m 38 s (1478 s) Cnt:(c/wc/ec)1544/0/1543 5.1%

NA offline.

Battery Info

Online:

Level lost [%]: Bat.: -61% (99% to 38%) [7.7%/h]

Voltage lost [mV]: (4136-3697) [55.2%/h]

Offline:

Level lost [%]: Bat.: -44% (100% to 56%) [6.9%/h]

Voltage lost [mV]: (4196-3793) [62.8%/h]

Screen time looks accurate. I didn't set a customref on the online test. I did the setup of the test, unplugged and put to sleep so the timing may be a few secs off.

The heat emanates from the corner where the 4330 is. There is another set of chips on the back of the MB. I guess freeze spray could help. I'll see if I have some. I'll check if we have an IR camera too, not just a thermometer.

The heating was the reason I opened it in the first place, so it predates the opening. I went in with plastic tools starting next to the sim card hatch. There is a number of feathered contacts (?) that connect to copper tape on the rear. They are intact.

Here is the BBStats from the online test:
