Battery life is horrible!

[RUthLEss03]

I'm currently running the XM6r3 ROM, and my battery life is less than half of what it was with WM5. Anyone else notice this? I'm thinking it might be related to the weather panel app.

First, did you flash an official rom before you upgraded to XM6r3? If you have a corrupted Extended ROM, this has been shown to cause battery life that goes down very quickly.

Second, Yes, other apps you put on that are constantly accessing the network and such can cause battery life to go down faster. Did you have WeatherPanel on WM5? DO you do Push email (and how often is it setup to check / push)? Are you running BatteryStatus and overclocking? That definetly pulls more on the battery.

What Radio are you using on your phone? Newer radios (2.47, 2.61, and 2.69) all pull more on the battery (IMO) than the stock 2.25 radios from T-Mobile and Cingular. I think 2.19 is probably the most efficient (but also doesn't have as good of reception for some, but seems to work well for me).

When I first started messing with custom roms here, first AKU 3.3 (so WM5) and then WM6 roms, I would gripe about less battery life. Then it hit me, I'm using my phone WAY more than I was when I was on stock WM5 as it was so unreliable for me on the official roms, and now the phone does so much more. I do WAY more with my phone now with these custom roms. So yeah, battery life is going to go down faster as the phone is now being used all the time.

Also, I do think most of the custom WM6 roms do use more battery, but look at how much more they are doing by default.

If you really want to do a comparison, then build a WM6 rom that looks just like an official WM5 and don't use the phone anymore than you did with WM5 (same apps, etc). I think you will find the battery life is much closer in that case (but you won't be happy since its not overclocked, missing great apps you are now used to, etc)...

I'm experiencing the same issues...with only 2 or 3 days of the iphone theme, with Slide2Unlock and WisBar, my battery barely makes it 18 hours.
I'm going to try the suggestion of flashing it back to original and them just the latest WM6 (screw the iphone stuff).

[RUthLEss03]

I do take into effect that I use it more than I did before. I did not have weather panel with wm5, and I also use battery status. I only recently started overclocking it. I also use direct push with our exchange server.

I flashed it with the T-Mobile rom before upgrading. The radio is 2.25.11.

I guess it just comes with the territory :) I'm going to have get in the habit of charging it more often, because I like it WAY more than WM5.

Very hypothetical and analytical description of the Battery consumption problem being faced,cudn't be explained more elaborately .
Stock wm5 Roms never had any such applications as new wm6 custom Roms offer.
secondly over clocking will definitely effect the battery power.

I noticed too. Probably the file connmrg.exe is taking all the CPU power, that's why the battery's life is so worse. Batterystatus gives a constantly 100% CPU usage display...

[mfrazzz]

IF you see battery status showing 100% cpu usage you have some other issue. Mine is only at 100% when I start an app or doing heavy work on it. Otherwise it idles back under 195Mhz most of the time with CPUscalar for me. Also depends on what ROM you are running and what apps you have added.

I have been using this rom since it was released and have had no problems at all with the battery life.

Is it possible to damage the battery by installing a new ROM? My 8125 battery was fine on old wm6 ROM, but after I installed XM6r3 (and yes, I did install t-mobile os before to clean it), my battery level goes through the floor.
I managed to charge it to over 50% and installed stock cingular rom, and with no extra applications installed, just the virgin cingular software, BT/wifi not enabled, just gsm radio I still see a drop of few % a minute! So basically, my phone is effectively cannot be detached from charger or my battery will drain very fast and loose ability to start os and begin charging again in the phone.
I can see (using wizard service tool) some cingular customization stuff on the hidden extended rom, does this mean extended rom is not a cause of this? Should I use format ROM tool in WST? (sorry for probably stupid questions)
Is there any way to check that it is indeed the battery being shot and not some obscure software issue? I find it hard to believe that good battery can go bad exactly at the same time as OS upgrade, I am hoping I am missing some obvious software fix

I believe its something else because my girlfriend calls me every morning and I take it out of the charger. I talk to her for a couple minutes 5 minutes tops and I hang up I look at batterystatus and it says 79% left tops. This is OD crazy I don't know if its the rom or the battery. I don't feel like paying 40 bux for a battery and same thing happens. I am currently installing a new rom I am gonna try this for acouple days and see what happens. I only noticed it for one rom but that rom I used for two to three weeks straight I didn't notice with the other roms because I never kept them for more then a day.

Strange enough before reading this post I thought that my phone's battery is dying. But know I can say that its definitely this XM6r3 ROM has some problem. To be precise there is definitely some application that eats the battery. As sometime my battery works fine and other time it just drain. If anyone can work on what application is eating the battery would be appreciated.

Rest the ROM is great.
