Getting really pissed about battery life
 

I would see previous posts about poor battery performance in the past, and just ignore them, because I had always had decent battery life. I found out early on how much push mail drains so I set it up for longer incriments of time.

Now I'm starting to see really absurd battery drains. I would charge my phone up at night and leave for work, and lets say at 8:30am this morning I unplugged it from the charger. Now at 11am, my meter shows 74%. I think over the course of that 2.5 hours, I installed skyfire, and read 2 emails and 2 text messages. I can't figure out what the hell has changed recently to make this problem start happening. I did have a charging cable go bad about that time. It would not charge the phone, and would constantly show errors if plugged into a computer. Wonder if it ruined my battery?

I run mightyrom, and recently switched from Sense to Titanium. I do run System Seven for mail push but it had never before caused any real drain. I'm thinking of just going to get my battery replaced, and maybe trying a fresh hard reset. I'm just a little disappointed that on average, I go from 8:30am -> maybe 9pm and down to under 40% with medium usage. Not playing any kind of media. I open some web pages, emails, text messages, and make some phone calls. Pretty lame how spotty the battery is.

wow, your getting better life than me. I'm typically at 40% or less by 1pm and putting it on the charger. I use the heck outta it tho. I just have lots of chargers available where I typically hang, work,home,homeoffice, car. I just live with it. Saw pics of a tp2 with a 3500mAh. Nice batt life, but big bad bulge not for me.
I do think my battery life is worse than when new(3 months ago). You could try a clean start(hard reset) and test it with nothing on for a bit. Might see something using lots a juice. Otherwise gotta just deal with it.

Re: Getting really pissed about battery life
 

hey guys,

i used to have battery problems all the time and i changed a few things to remedy this problem...i had google latitude installed which probably killed the battery cause it keep constantly trying to update my location, push email was set to every 2 hours, push internet was set to every 4 hours, and slide2unlock...and on top of all this i dont get reception at work which kills the battery cause it it constantly searching for a signal. After disabling most of these service the battery has dramatically improved. I'll agree the battery on this phone is pretty bad compared to my previous phones but considering it has a 3.6 screen and is very web/media-centric im not surprised.

Re: Getting really pissed about battery life
 

hmm now that I think about it... Slide2Unlock is something I added recently but didn't think it contributed to battery life issues. Is that really true? I just removed System Seven but maybe I didnt need to. Maybe s2u2 is the culprit?
I might try the discharge/recharge process once as well.

Re: Getting really pissed about battery life
 

Wow. And I have the opposite experience. My TP1 lasted 10-12 hours in a regular work day, and it wasn't my primary number. Now I've swapped my primary to the TP2, and I get atleast 1.5 and possibly 2 days out of a single charge. I pulled my phone off the charger this morning at 6:30. I'm at 70%, and I've installed Swype, sent > 75 text messages, and have Acrobat running in the background all the time (I like to read!). I'm running the 2nd to latest MightyROM. Sync with exchange, but every 15 minutes during the day. (30 at night). No push pages setup(push internet disabled). S2U2 is running as well.

Re: Getting really pissed about battery life
 

I'm running Energy's latest 6.5.3 Rom, Dec 7 28011 with S2U2 and easily get 1.5+ days. It seems to drain quickly for the first 5-10%, then slows to a crawl. Sweet.

Regarding S2U2, I saw huge increase in batter drain on my TP, but with the TP2 my battery life actually seems to improve with S2U2.

Re: Getting really pissed about battery life
 

there is a good chance that s2u2 may be one of the problems...ive read a couple threads where they said it was causing a battery drain...i also disabled the automatic screen dimmer..i felt that also reduced my battery life cause i think it takes more energy dimming and brightening the screen as opposed to jus keeping it at a set brightness

EDIT: supposedly some of the 1% battery increment cabs also reduce battery life..which i find totally stupid

Re: Getting really pissed about battery life
 

It must be something I did in the course of tweaking settings. I might just hard reset with mm latest and not try and tweak anything.

Re: Getting really pissed about battery life
 

have you guys tried a battery reset yet?

There is a rumor that there's a bug in WM that causes it to measure the half-full battery charge on a new phone as full(You know how when you buy a new phone, how the battery is only half full), and it will only charge to that level from then on no matter how much you calibrate it. I dunno how truthful this rumor is, but I have noticed a HUGE difference after doing this.

1. Let the phone go completely dead, until you can't even boot it up.

2. Charge for about 5 minutes, just long enough to get enough of a charge to boot up & hard reset(obviously, back up your data before you do this step).

3. Let the phone do it's configurations & reset, then plug it back in & let it charge OVERNIGHT.

And S2U2 is a major battery hog. I won't use it.

Re: Getting really pissed about battery life
 

I think I get pretty good battery life. In fact I was just testing it today for playing movies. I let the phone sit and play Casino Royal at 50% brightness. After the first time through the battery was well above 50%. I left push running all day and still had 15% battery life after it played the 2hr+ movie 2 times. Pretty good for that type of media usage IMHO.

I am running a1jatt REV1 6.5.1 ROM and also running S2U2.

Re: Getting really pissed about battery life
 

I had an issue when I had Skyfire installed that would keep my data connection open and cause excessive battery drain (The phone would also get pretty warm). Once I uninstalled Skyfire that issue went away. I don't know if this could still be an issue with the latest version or not that was just released.

Re: Getting really pissed about battery life
 

I have noticed a big difference after doing a number of things. Not sure which really fixed it but at this point it doesnt matter :-)
I replaced s2u2 with smartlock. Removed System Seven and just set up gmail activesync at like 15 minute intervals. Changed the backlight setting to be constant instead of automatic. With all of this, I'm not seeing a fast drain like before.
Thanks everyone for feedback!

Re: Getting really pissed about battery life
 

iheard that was an issue with mighty....on juicy for me i could take it off the charger at 8am and by 8am the next day i think im at 30-40%

Re: Getting really pissed about battery life
 

I've been running on Energy ROMs and the previous ROM Leo 28008 wasn't great on battery and BackLight was auto. Then I installed 28011 and set back light to fixed (30 percent I think). Battery has been outstanding now. Push Mail is off and data is up continuos due to HTC weather.

Engery just send a tweet saying he thinks the battery is outstanding on 28011 as well. So it may be the ROM.

Re: Getting really pissed about battery life
 

I have stuck with mightyrom after trying a few others... and am now using titanium. Do you think Juicy or Energy would be better for battery purposes if I plan to not even use Sense?

Re: Getting really pissed about battery life
 

I am on the Energy Leo ROM. When i first installed it i was having simaler issues to you with my battery generally going from about 100% to dead but the time i got home from work. Ended up noticing that his had a 3g option that is auto-set to on when you install. I disabled it and now get ~ 1.5-2 days per full charge.

Re: Getting really pissed about battery life
 

So what does that mean? It disables a 3G connection?

Re: Getting really pissed about battery life
 

+1 here. Running SSK's rom. Email push on, S2U2 installed.

I can easily get through an entire day on 1 charge, while I was only getting half a day on the TP1 with basically the same usage/software.

Re: Getting really pissed about battery life
 

I've been seeing higher drains while using nueRom's battery driver for TP2, (the one that shows 1% increments.) as well as the one in Good2Life's cleanup cab. You can follow the discussion HERE.

Re: Getting really pissed about battery life
 

That's an interesting theory, but Lithium batteries in our phones are smart batteries, their internal controls is what determines if it's full or not. The whole memory reset theories come from Nickel batteries, which actually needed a full discharge and recharge every once in a while to help the battery "remember" it's capacity. With a lithium battery, they degenerate faster below 30% or above 80%, basically meaning they if you are constantly charging the battery or keep it at constant low charge, it will kill the battery faster than if you used it in a normal manner.

Re: Getting really pissed about battery life
 

the first thing people need to do to increase battery life is stop using the bloated s2u2

I had problems with S2U2 draining my battery...Aso when I leave the nueROM batttery meter open, it drains my battery like crazy, so I could see how a 1% driver could suck up some battery

Re: Getting really pissed about battery life
 

Err - I'm using S2U2, 15 minute emails from 8am - 10pm and 30 minute emails from 10pm - 8am and I get atleast 36, usually 48-50 hours out of a charge. I usually send about 50 SMS/day, as well as reading books (Acrobat Reader - which I leave open) during the day, periodically - plus some other random usage. I'm not entirely sure it is S2U2. I don't have the 1% battery driver, though.

Re: Getting really pissed about battery life
 

I have been getting inconsistent battery life, especially when I ride local Rapid Transit to work. What I usually notice is that it sometime (about 90% of time) drain battery like crazy after in and out of tunnel and underground a few time. That got me to think, maybe the phone is scanning for signal.

Looking around the phone I notice that while it is in global mode, it will search both the CDMA and GSM for signal which leads me to guess it might be scanning for CDMA then GSM, then CDMA and somehow get into a loop. I can even feel the battery gets hot and it would be dead in 2-3 hours from a fresh charge.

Turning off the global mode and set it to CDMA only has greatly improved my battery and have not had the drain problem since.

setting -> phone network mode -> network tab -> change to CDMA only and see if that helps.
