Battery life is horrible!

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).

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...

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.

No Problem with battery
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
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 (Battery life)
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.

Battery life?

Hi there,
I notice now for a while that the TyTN II has incredibly short battery life.
I've got a few questions about that. Are there ROMS out here, with which the battery life is longer?
And are there batteries out there with a higher capacity than 1350mah, but who still fit in the TyTN II without the need of a new back cover?
Thanks for your time
Regards,
Dennis

Although I don't have any answers, you are reading my mind. Hopefully one of the 'gurus' here have some answers!

You can read the posts under Kaiser accessories, this will help you find extended life batteries. I know there are a few posts there. As far as the Roms go, the fewer programs you have running the better off you are. I know active sync is a huge memory hog. I am using XDA live 1.3 and is great but it is for AT&T. I wish I could help YOU out more- trust me.

I switch from 3G to Edge when I am not browsing. My battery life greatly increased and I do use direct push.
-McMex

So the XDA Live 1.3 is only for the AT&T Tilt? Not the TyTN II?
Anyway, besides this, I don't use 3G. Even without using the internet on my PDA, the batterylife is soooo darn short!
I have WM6 version 5.2.1921 (Build 18521.0.7.0), with latest Radio.
All the battery options I see here above 1600mAh, make the TyTN II bigger as far as I know...
regards,
DM

You don't use 3G did you shut it off? Can you elaborate a little on short what is short to you one full day?
-McMex

Does edge use more power than normal GPRS?

Thanks!
Hi Martin!
Thanks for the tips. I will check out the area you suggested. I think I need to stop watching my slingbox on my Tytyn II ... I'm sure that would save me a lot of juice . I just can't seem to live without my American TV!
I think I will just buy a spare battery to swap with. I don't want to increase the size (or weight) of this thing any further!

As far as I know I shut it off. Under phone settings, I switched to GSM.
On a full day, hard to say. When I use the device "now and then" to lookup appointments and make a few calls, there's a quarter left at the end of the day.
Whatever I do, I need to recharge it every end of the day. It's a huge difference compared to an older Hermes device I owned.
Regards,
Dennis

Yeah, same experience here as well. Very very disappointing indeed from an otherwise great PPC!

I stay on 3G all day with Direct Push (about 60 messages / day) and about maybe an hour total of phone calls / 2 days and I am able to stay on for 2 complete work days (i.e, remove phone from charger Monday morning and not have to recharge until Tuesday bedtime).
With Edge only, I only last until the end of the same day.
Signal Strength is key. I get full-bore signal strength on 3G at home and work. I get 1~2 bars of EDGE at the same locations...

Interesting... I'll try setting my phone's "Network type and GSM/UMTS band" both to "Auto". I switched to GSM, because the signal strength seems rather low with 3G for some reason... Besides this, I've been told that 3G consumes more power?
Cheers.

my battery on my tilt goest down to about 88% by the end of a day with me using it marginally...(checking time, text messaging, not too much talking on it though)

WOW!!!.... That is hard to believe. Not that I doubt you, just that don't I'm down to 10% by the end of my day with just light use. You wouldn't consider trading phones would you? LOL!!!...

So it the end of the day you battery is at 88%? Or are you saying it losses 88% by days end? If the former, WOW... at that rate it would last you about 8 days!
Do either of you sync you phone to a PC during the day?

I get about 2 full work days as well with normal usage & about the same number of emails. I also keep bluetooth on. All in all I'd say that Kaiser battery life is better than Hermes.

I can get about a day and some change on one charge. But I don't think it was better than my Hermes. I usually charge my phone before I sleep< but even at 100% my tilt is around 89% when I get up after about 7 hours sleep. My Hermes would still read 100% and yes i do understand Hermes operates in increments of 10. Do you think the poor batter life can be attributed to the lack of ATI Imageon drivers. Since now even the simplest of rendering has to take up valuable cpu cycles, which could have been handled by the dedicated video hardware.

by the end of the day its at 88% sorry for not being clear, I dont sych it very often...just to add music or to toss a new rom on there.

Same for me. I had some issues with cooked ROMs with older radio...used to last about a day max. Now, I'm on CUSTEL's latest ROM with the latest radio. Not sure if it's the ROM or the radio software, but I'm on pretty much 2 full days. I'm right on 3G/Edge margin area...gets about 3-4 bars with EDGE, about 1-2 bars with 3G / H. Goes back and forth. I get about 100+ emails a day via continuously connected Direct Push on top of normal phone call usage.
So far, I'm pretty happy with the battery life. Definitely better than my 8525.

What the hell am I doing wrong?? I barely get though a whole day without charging. I only use my slingbox a bit and am on Wifi most times. I have my settings to automatic but think I usually connect via GPRS vs 3G when I'm not on wifi. I don't even have my bluetooth on
I am using the standard HTC ROM on my HTC Tytyn II that I downloaded from here and flashed (all by myself thank you). I needed WWE but my phone came with Swedish.
Sorry to hijack your thread, but I need answers!

best radio for duttys v3?-little talk lot of drain

hey guys Ive tried .10 and it seemed to suck the battery down from a full charge in the morning by that night it would be dead and i don't talk on it a whole lot any, suggestions?

did u try turn off the 3G (if u not using it)?

In the chicagoland area i'm using 11.31 and I see a difference in battery life due to the fact that is stays 3G more consistently than before...

Based on your comment about 3G, I am assuming you mean the battery life is shorter. Am I right?

I'm in Florida and use 11.31 and use hsdpa and 3g all day. By the end of the day my battery is at 65%. Now if I use GPS it can suck the battery down real quick.

In my opinion so far 1.27.12.17 is best for battery saving with good 3G reception, but 1.27.12.32 is best for 3G and in weak signal areas.

It's indicated by several posts in the big Dutty V2/V3-thread that some experience heavy/extreme battery drain, regardless of radio-ROM used, so which radio you use might not be the only explanation to this. It doesn't necessarily have to do with installed software and/or push-mail etc either.
In my case I have tested .12.10, .11, .17 and .32 as well as .11.31 as well as reflashes, hardresets and whatnot and no luck with any of them. I experience significally worse battery life than just a few ROMs ago. This is 2G/EDGE-mode. 3G I don't even want to talk about
/Mac

thanks for the info
after reading what has been said i believe it may jsust be the rom. Dont get me wrong i love it but i have tried the .17 and the .10 and haven't noticed much of a change. Thanks for everybodys input

very bad talk time on my Fuze! please advise

I just received my fuze for 2 weeks, but my talk time is really bad. I tried almost every radio available with matching rilphone.dll. I see its listed at least 5 hours talk time, but my battery drop like 15% battery with 20 mins talk time. that's with 3G off, data off. just Bluetooth and Phone on. I get about the similar battery life with all the radios.

Well , you can just turn the bluetooth off. I have the same problem when I using bluetooth headset .
I guess the CPU and touch screen takes a lot of power , I have to charge my raphael every day.
maybe you can buy a larger battery .

what other programs are you running? Running this like SPB mobile shell and TF3D are big battery drains. Also, keeping your other programs running in the background is bad for the batterylife. try turning off all programs that you're not using after you're done with them.

I do have SPB Mobile Shell running. does SPB Mobile Shell affect talk time battery life? because it drains about 2-3% the whole night when I sleep.

Bluetooth!
Same here, while using bluetooth, the battery drains like anything. I dont use bluetooth anymore. It sucks but cant help.

sorry for not replying after a while.
i have SPB MS3 and it doesnt really drain it too much (a little bit but not too much)
what rom/radio are you using? those can be very significant factors for battery drain

i dont got a problem with mine, im running XBMods Rhodium TF3D with the AT&T Leaked ROM, with radio 1.12.25.19 i get like 7 hours out of it, without TF3D i get like 8.5 hours, and the reason i have that much its because i keep the phone off as in the screen, and like also i dont do anything to it like txt while on the phone and also signal is also a role in battery life as well

I had bad battery performance with Stock AT&T ROM
Then I flashed the Energy ROM 2.0 two weeks back and now the battery performance is much better

Possible Solution
Battery life on my Fuze sucked so bad the first week I had it. I saw it drop 10 percent just by looking at it for 10 minutes. So i started to dig around here on these awesome forums and the solution was simple. Whether you use stock rom or custom rom. Just find a way to turn off 3g networking. There are a bunch of tricks to do it. One thing i noticed is that my area has barely noticable 3g coverage so i found the signal reception always 1 or 2 bars. When i disabled the 3g connection, i found my battery increased dramatically. You can see for yourself by using DrSigstat. With the 3g its using over 200mah constantly trying to acquire the weak signal. This uses the battery very quickly. With the 3g off I am using as of this message 53Mah which extends battery life immensely. I am only connected to edge checking email every 30 minutes and this phone is usable. If you need the speed you simply toggle the 3g back on. The 3g network drains battery quick disable it I know there are a bunch of CABS to do it and even add it to the Comm Manager. Hopefully this helps.

I had the same problem, but that all changed when I took the phone on a Tahoe trip. Since I was using Garmin, the phone was ON most of the time and about 2 or 3 times the battery completely drained -- the phone got switched off on those occasions. And I used Motorola car charger to charge the phone during that trip.
When I got home a couple of days later, all of a sudden, the battery holds up like anything. Now I can go on without charging for upto 3 days with moderate use of course, but I do have google calendar and contacts sync'd up using activesync, 3G is always on and email sync'd thru pop3. weather and stocks updated few times a day as well.
And soon after I flashed EnergyROM with latest radio and matching rilphone.dll and now I have to admit that its a totally different experience with this ROM and the battery holds really well as well.
So I think that draining the battery completely and charging it using Motorola charger helped and then the EneryROM has a part to play as well.
Like zalooa said above, if you are in a poor 3G coverage area, it's going to drain your battery a lot faster, so location matters as well.

battery drain fix - alternate method!

This is a sister-thread to "Battery Drain Fix" for the g2x that lists a factory reset as a possible fix to battery drain issues.
First, let me say that even if you do not currently have battery drain issues with your G2X, that doesn't mean that you're immune. My battery has been phenomenal at times, abysmal at others. I've done the factory reset and that DID help for awhile, but battery problems arose again.
I believe the problem that plagued my phone was the dreaded 50% cell standby problem. If you're unaware of this problem, essentially the issue is that "cell standby" (found under settings --> about phone --> battery use) is at or around 50% always -- in other words, it doesn't matter that the phone has fine reception, is or is not being used, or even has the signal active (that's right, the problem persists even with airplane mode activated).
While I do recommend the factory reset method (assuming that you haven't had your phone too long, as it can be a real pain to reconfigure everything if you've set it up how you like it over many weeks...), I think this alternate method is something we should all do as well. In brief, you'll want to do the following:
-open dial pad and dial *#*#4636#*#* (If Testing menu doesn't come up than click "Call" and it will come up)
-Go to Phone information
-Scroll down and you'll see preferred network type
-click it and switch it to GSM/WCDMA auto
-click back button
After taking these steps, you should see an immediate improvement to your battery drain problems, as well as much faster battery charge times. Additionally, your cell standby % should decrease dramatically.

Isn't the same effect achievable from the Network Settings? No need to go to the secret menu. Unless I'm missing something.

Interesting. I've had mine set to 2G networks only, so I hadn't noticed. I'll switch it over as well, and see what happens. I've been getting great battery life though, so this is purely an exercise in curiosity. Regardless, the root cause of this problem has already been determined- the drivers are ****ty. CyanogenMod is liable to fix this up immensely.

I changed mine too and I will report back if I notice any improvements

The battery reporting is terrible so cell standby could be nothing really.

I believe doing this also fixes the GsmTracker poll failure in one of the threads. At least mine is no longer red but green (in the logs)

I can personally attest to the fact that this does absolutely nothing different. I have had my phone switched between WCDMA, GSM and WCDMA/GSM auto just to see if there was any difference for the past few days. My device has battery life worse than the HTC Thunderbolt that I returned, and being only 7 days in I'm thinking about doing the same to this device. I'm definitely experiencing buyers remorse.

@TheMightiest -- did you do a factory reset first and then try this method?

I've factory reset my device 5 times, just drained it, for the 5th time and recharging it as we speak. I still lose between 15-30% per hour if data is enabled...just like the HTC Thunderbolt. At least I got 19mb download with the Thunderbolt, I'm getting an average of 6mb with the G2x, which ain't bad, i'm just saying.

Mine was set on gsm only. I've just made the switch so i'll report back if there is a difference or not.

I've read a lot on the whole philosophy of "drain completely and recharge fully to maximize battery life," and from the looks of it, that method doesn't do anything for Lithium-Ion batteries, which have no memory effect (http://en.wikipedia.org/wiki/Lithium-ion_battery - not that wikipedia is the ultimate authority on things, but hey, it's a link at least).
Your battery sounds WAY worse than others' batteries...you should seriously consider returning it and getting a new one.

Well, my cell standby percentage has not gone down at all, but still my battery consumption is much improved.
As was stated in this thread, the battery readings may be very off the mark from actual battery life, however, that fact doesn't help explain why some of us only were getting 5-6 hours of battery life with moderate (and sometimes no) use. There obviously is a problem, and CM7 may well fix it, but the method in this thread has definitely helped my phone stay on longer...irrespective of battery readings.

This is not the reason people on these forums recommend draining completely and charging fully. The reason is that in order for your phone to get a semi-accurate idea of what percentage the remaining battery life is at. With this particular phone, however this is probably still a lost cause as the driver will never give an accurate approximation of remaining life.
At any rate, the full drain, full charge is a one time thing. This will also in no way extend battery life (but I haven't seen anyone on the forums claim this either). You can, however, extend battery life by keeping the charge at ~80% and keeping it as cool as possible.
On a side note, great to see yet ANOTHER battery thread

It's amazing right - we have dual core 1Ghz processors in our smartphones with 1GB of RAM and high res screens, 4G data, etc. etc. yet battery technology hasn't advanced in years. Whoever improves battery tech is going to be the richest person in the world. Think about it.
Edit: Btw, mine was set to WCDMA preferred although in Network Settings it was on Auto so I changed it to Auto.

Okay. I read the original thread and it sounds like the 50% is refering to the "Time Without Signal" value when you actually click on Cell Standby. Not the value of Cell Standby itself.
My G1 running FroYo last month had at least 50% Cell Standby with only ~1% Time Without Signal and the battery lasted about 2.5 days with moderate use.
I'm not an EE so obviously, I could be wrong about this.

You sir have just received a thanks, because this could also be the cause of some of our data issues and how the phone picks up on 3G vs 4G signal. Im doing some testing regarding APN and now with this hidden menu. Have noticed my speeds are a little bit better then they were. Battery drain was not a problem for me before.

Thank you! i did this to mine and my husbands g2x's last night. seems to have fixed the switching issue
