Poll: How Long Does Your Battery Last? - Page 5

well, just to clarify the batteries don't have memory per say, but the phone does. there's chip level control of the charge, and software control. the trick is getting both to agree. best way to do this is letting the phone completely die, 0%. then fully charge.

I've been running the stock rom (fully tweaked) on my tp for a few months now, and honestly the battery performance is on par with every cell phone i've ever had. (minus 6700 and 6800, as they were pretty bad.)

sorry I can't give more specifics on use, cuz really I don't pay attention. I have a spare, and typically put it on the charger at night. only time I have trouble with it dying is when i'm talking alot or using data alot, especially in the hot weather we've been having.

So if the phone really has a memory, what do you do when you switch batteries to reset that memory? I too have 2 batteries and was wondering that. I was trying to understand more with the battery monitor app and started a thread about it a little while ago, http://forum.ppcgeeks.com/showthread.php?t=70648 but I haven't really gotten much feedback. Any thoughts?

Just run it down all the way. Do this once and it should be fine.

Actually I got a new battery and it seems to be lasting a lot longer. I think my old battery was just bad because I wouldn't be able to make it through a day but now I can.

Did you get one from Sprint or where? Mine seems to be having a tough time making it a day as well, so I might try to get a new one (have read sprint gives them to people, but I've been unlucky so far).

1 ) How long does your battery last? 24 Hours
2 ) Which ROM are you running? Reborn
3 ) What tweaks have you done besides what came with your ROM? Disabled voice command, disabled auto back light, manual updates on everything
4 ) How many text messages do you approximately receive a day? 40-100
5 ) How many minutes on the phone do you spend on the average each day? 20 mins MAYBE
6 ) How many data related activities do you do? Include how frequent you check e-mail. A lot of twitter, some email....weather updates. Not too much
7 ) Do you use bluetooth or wi-fi a lot and how much? Wifi at home as I have no service...also adding to battery drain
8 ) Do you have any practical suggestions not already mentioned? Close your apps, take stuff off of auto, give roms a few days after a flash to calibrate battery

@ mwalt2; if their in your area, you could drop the name uscc in the convo and see where it leads.

I have 3 batteries and 2 phones. 1 PAM so it commonly runs til dead (thanks no2! boo qualcomm), and my primary rarely dies.
I alwasy get variations between the 3 batteries when I boot, but since i've had a consistent rom setup going a few weeks I did almost have everything totally calibrated and down pat.
I recently tried a new kitchen

and now just charging a dead battery (via PAM phone) in my primary phone with new rom and @ boot it reads 90% on PAM i get 80%. for fun I went ahead checked for the battery that was in PAM (15%) and it showed 35% in my primary, pulled and rebooted and it shows 20% now consistently.

I know that might be hard to follow, but I think it shows just how much inconsistency is involved with batteries, and not that it's the batteries fault, just all the bells and whistles put in to manage them have to error tward safety.

so basically after a rom flash drain(+boot) and fully charge(+boot) all batteries, but 1 cycle should do it.
(+boot = means to boot again after death, and boot after the full charge if charged off)
i have not noticed a difference in charging ON or OFF as long as the radio is cool.

Is that with heavy usage

The lowest I've ever seen the battery monitor register in it's log file in sleep mode is 13ma, assuming battery monitor not running maybe we get to 10ma, that would give us 135 hours maximum on a normal cdma 1350 mah battery, that's an absolute maximum standy time in sleep mode of about 5 1/2 days. With light usage I can't imagine any normal battery lasting more that 3 days. Are people that claim a week even turning the phone on or is that how long is takes a battery to go dead sitting unattached to the phone? I find my spare battery holds it's charge a real long time when it's sitting unattached in my pocket!
