My Touchpad drains 400+mah with the WiFi turned off, but once turned on, battery drain goes up to 1700+mah.

Could this be a faulty WiFi? I haven't had any issues with it till one night it just started to get really hot on the back near the camera (this was also when WiFi was on). Anyone have any ideas?

I got all drain values from Govnah

My Pre+ has done the same a couple of times... Have you tried rebooting both the TP and the router?

Yes, I have tried reformatting it repeatedly too, Even drained the battery and recharged it, I don't think the router has anything to do with it though.. as long as the wifi is turned on, no matter if it's connected to a router or not, it still drains over 1700ma to 1800ma charge

Oh I see. Either the WiFi radio's firmware is corrupted or the chip itself is going bad.

If it's the latter, someone here can probably sell you a new WiFi board from a parted up Touchpad...

How can I check the WiFi radio firmware? Also is the WiFi board easy to replace if broken?
Otherwise I guess I'll just have to use my TP without WiFi.

I don't think you can flash the firmware to the chip. You can only load it while loading the driver for it.

You could try observing why the system is using so much battery. Look at the WiFi icon and see if it drops out intermittently. Check the logs to see if it show any problems. Run PmWiFiService by itself and see if it produces anything exceptional.

As mentioned before, It only picks up if the WiFi is on, It connects fine and works fine as well. Everything's fine except the fact that once turned on, Battery drain increases to 1600+ and the back of the touchpad heats up. It remains heated even when on sleep IF the WiFi is left on during sleep. Will try to get the logs as soon as I can.
