Seidio 2600mAh extended battery

[preinvent]

Yeah the mV and mV% seem to be the best readings to use for Seidio. The estimated time left and time dead can easily be wrong.

I'm looking at ways of figuring out the estimated time based on mV readings, but it's not straightforward. mV readings start high (around 4200) and drop fairly quickly to a plateau of around 3700 (makes sense.. the batteries are 3.7V batteries) then just before they die they drop down to 3.5 ish. I was hoping for a linear discharge, but this isn't the case.

Hi Matt.... will it be possible to have a button that says "stop learning" or something of that nature?

I don't mind spending a few days or even a couple of weeks getting battery left calibrated just perfect but I don't want it to continue learning because I want to be able to top my battery off and charge whenever I can "especially since I don't have the extended battery at the moment" to avoid running out.

I'm concerned that once I get it calibrated, my change of habits " topping off frequently" will skew the readout and it will stop telling me "accurately" how much time I have left till discharge?

Does that make sense?.. not sure if I explained it right.

I normally never let my batteries get near dead.. just like I don't routinely run my tank dry of gas in my car before I fillup.. but I want to keep accurate readings.

Are my concerns unfounded or do you have any suggestions?

Makes perfect sense to disable calibration, that's definitely one way that this would work.

For folks who aren't techy at all... you could also have it auto stop calibration after it shows "accurate"... just a thought....

If someones habits change dramatically, they always have the option to recalibrate, and then the counter would restart to auto kill calibration again once battery left felt like readings were accurate.

Got the 2800mAh today and charging as we speak 4120MV

That's a good idea. If you change your habits then you can always re-calibrate.

I said it before, but maybe an option for the OEM battery and for the extended battery in the Settings. That way you're not forced to use the same algorithms.

EDIT: The battery died at about 34 hours. I've got it charging now on Seidio's multi-charger. The last voltage was 3276mV and it was pretty quick from 3456mv.

Wondering if anyone noticed an increase in the phone's internal temp with the extended battery?

I haven't; using battery left to gauge. I only noticed a rise in internal temperature when i have the charger plugged in and am using something like wifi tethering.

I haven't either. Not scientific, but I admit to playing Robo Defense and had noticed the stock battery feeling hot at times when running that game on high speed. I have not noticed that with the extended battery.

It seems like I may have to do my calibration for Battery Left while I am on vacation :dry:. It has been impossible so far to have the phone die at a convenient time so that I can give it a good 8-10 hours to charge to full (and we have to do this twice?). I am assuming that you have to have an uninterrupted charge cycle during the calibration period; am I right about this? I think windstring's suggestion is an excellent one.

This can't be good, tethering with my stock battery gives me a battery temp of 98.6 and a OMAP3 temp of 105.0/107.0 with the 2800mah battery tethering without being plugged in and running stock setcpu at 600 I have a battery temp of 102.2 and OMAP3 temp of 118.2/120.2


Update: I think I figured out the issue, while tethering all background apps need to be killed my final temp while tethering with the 2800 battery was 102 for the battery and the OMAP3 105/107

How much longer will this battery last than the original?

If it ever gets fixed

I would LOVE to have an extended life battery for my Moto Droid, but after reading all of the comments and especially re Battery Life, or for that matter, any other battery meter app, I just don't think I would be prudent to go to this batt at this time. I'm going to keep tracking, and if anyone finds success in monitoring the actual time left on this batt, then I will jump for the batt + charger.

Right now, with the stock batt, on Batt Left:
time left: 23.07
Time dead: 8:30 am
Acc: Moderate
estimated %: 87%
System %: 80%
Full Batt Life: 26:35

An excellent question, but this is a real case of YMMV.

I've never really ran the OEM battery down to see the exact time, but I've run it to 20% from 7am to 11pm (or 14 hours). The best I've gotten so far with the extended battery is 36 hours. Mind you, they want you to run it dry and do a full charge 5 or 6 times initially. Windstrings has gotten 54 hours (at least).

After 18 hours on the mulit-charger (5th full charge), it came off with 4147mV. The ideal initial voltage should be between 4180 and 4200. Just doesn't happen for me. I may have a defective battery or just needs more breaking in. I dunno.

I've found that after removing my stock or extended batteries from the Seidio wall charger that neither is ever at a full 4204-4207mV charge. They're usually at about 4179mV as soon as the phone powers up. Same as when i leave my phone and standard battery in the Motorola multimedia cradle. I end up having to charge the phone directly from the wall outlet for a few minutes before the battery is truly full.

I'd say mine lasts about a little less than twice what my stock does.
