I also see this behaviour; my phone begins draining battery when I charge it via my computer. Charging via the charger or carcharger doesn't result in batterydrain, but charging via computer does.

I also see battery drain occur when I did a bluetooth enable and disable sequence.

Today I saw another strange behaviour; I didn't use bluetooth and haven't connected my phone to a computer. I only changed the gouvernor to Convervative and noticed battery drain this morning.

Well, I have the same problem. The difference is that I had it with 6.0. I was just about to wipe everything and start from scratch, when I found 6.1 and installed it.For about 2.5 hours, my battery went from 98% to 14%.

The biggest problem is that when I go to sleep, the battery dies and the alarm does not wake me up (My old Siemens MC60 fires the alarm even if the phone is switched off, with no battery to run calls...Great thing!)

The RED button was not set to make my device go to sleep for some reason with 6.1. I do not know what it was set to with 6.0 but I was running it for 2-3 months before it started draining the battery (no changes made during that time).

I remember I installed some apps at the same time I started noticing this battery drain. But going through the running processes, I found nothing closely connected to those new apps (Quickoffice and some stupid game).

I do not think it is the apps, because I tried removing them. I had that issue with 6.0 and now with 6.1. My button is set to "go to sleep". Everybody is quoting that changelog with the "reboot your phone after removing the usb", but this is for the new kernel. And I had the problem with the one that was in the 6.0 (the first final version posted here).

EDIT: I forgot to mention, 6.1 is way faster than any other CM I have ever tried. I was looking at a friend's Galaxy S and I thought "My phone sucks, too slow for anything", but with 6.1 it's at the front line again.

Probably people have tried this already, but if you're having problems, have you reset the battery stats?  My first day of running 6.1RC1, I used the entire battery in ~3 hrs after unplugging from AC; weirdly, the dialer had used something like 40% even though I hadn't made a call.  I let it charge on AC 'til full, then rebooted to recovery, wiped the battery stats, waited about 20 minutes then unplugged it, and let the battery drain so far that it couldn't turn on anymore.  After the subsequent recharge, my battery behavior is back to normal.

Pls tell us where is the newest kernel of 35.8 ? Thanks!

Other than on my SD card you can get it here :-P

I also attempted to attach it.
You can also download it in rom manager if you bought the pro version. :-) good luck!

Another vote confirming USB charging kills the battery. Before this thread, my phone would die by 4 PM (less than 8 hours of juice). Today, turned my phone off and back on this morning and came home at 6 PM with 40% of my battery!

Still, it'll be tough to remember this as I tether a lot and don't always remember to reboot. Is there a kernel that fixes this?

PS - I'm running the official T-mobile ROM on a G1 (or rather Dev Phone 1).

So, with the new kernel will fix the problem with the battery ?

There is no new kernel that solves the problem.

The new kernel worked better for me. However charging the phone fully with it powered off and then booting into recovery and erasing battery stats seems to have worked.

Thank you! But this kernel still didnot solve the problem.

Is there any downside on using the older kernel 2.6.34.7 with CM6 RC1 ?
Are the new drivers cyanogen mentions included in this kernal?

Thanks.

I've used both, 2.6.34.7 seems to me a little slower, it doesn't allow you to OC up to 614Mhz. Now I'm using 2.6.35.7 with reboots after charging because I feel it faster, but it's just my opinion, I'm not really sure.

Anyway, with 2.6.34.7 everything will work fine, I didn't have any problems at all.

This worked for me. I was losing a full charge in about 2 hours not using the phone at all, tried this and it seems to be close to normal again.

It is listed as "known issue" and it will go to "resolved issues" soon. I am happy with the workaround since the phone works way better than with 6.0 and it is worth the efforts of pressing reboot

I think not so soon , it looks like it is  not easy to remove this bug - it is already known for about 1 month . Maybe can we ask kernel developers together to focus on that problem ?

I've had CM draining the battery super fast since cm5 releases.

For me, I've noticed that I spend most of my time in rather marginal 3g coverage areas, so the phone is forever switching between 3g and 2g.  If I set it to use 2g only, my battery lasts literally for days, currently it's at 23:11:57 since unplugged and at 75%, with probably an hour of phone calls, a few texts and some twitter browsing over wifi.

On the OTA 2.2 it was getting down to more like 50% with 3g enabled after 24 hours.  With stock 1.6  (Vodafone AU) and cm4 I was, with 3g on, getting similar performance to cm6 with 3g off.

When I was in the big smoke (Sydney) last week, with strong 3g coverage and not switching to 2g all the time, battery performance was subjectively much better, I didn't pay too much attention to my phone, was busy doing things.

Most G1 batteries are 2 years old, (mine was). I had horrible battery life and thought it was the kerel, I tried all the fixes with no luck.  Yesterday I pulled the battery.  It was slightly convex.  I swapped it for another from my wifes dropped g1 and I now have acceptable life.  I unplugged this morning and had 50 percent left at 2pm.  I'll take that after what I had, and I ordered a new one...  Check your batteries.

Main problem is not a battery age , but kernel . 34.x kernels are almost free of issue while 35.x suffer heavily . I also have theory that bug might be connected with "Debuging USB" option , which is advised to be ON on rooted phones .

Doesn't Pershoot's 2.6.35 kernel supposed to have some bad battery drainage after connecting you phone through USB?
Is that getting fixed just after a reboot? or do you have to reboot every time you connected it to a computer using USB...if that's still the case I prefer to keep using 2.6.34

I use 2.6.35.8 and use usb all the time with no problems and do not reboot, left my phone unplugged all night last night right after I had been USB tethering and picked up the phone 9 hours later to 96% battery. No reboot no nothing just unplugged from usb and went to sleep. Maybe I'm just lucky, or maybe there is another issue causing this. I thought the issue was for versions older than Froyo anyways, so it shouldn't matter for us that are on 6.0 and above.

I reboot the phone everytime I connect the USB, I don't know if it's needed but after 16 hours I'm at 54%, I don't think it's a bad time.

[iparker]

I'm at 55% running on 44 hours.

I have 6.1rc1 running.

However, before I updated from 6.0 my battery life was much worst.

Also, I only charge via adapter.

[guille26]

26 hours and 32% (internet browsing, wifi, calls, mailing...using it a lot), much better than 6.0, that's for sure.

I feel weird not connecting it every day at work and at home.
