Seidio 2600mAh extended battery

Hey windstrings. Just out of curiousity, can you give us a bit of a breakdown on your usage when you receive 51 hours (or something close).

Like, how much display time you use. Phone time, etc. If it's too much trouble, don't worry about...but I would like to see how my time compares to yours. I am doing a full cycle today to recalibrate Battery Left, and I'm currently at 3870 mv with about 1 1/2 hours of display time and only about 5 minutes of phone calls.

Unfortunately, with DroidMod, you can't get readings on any other uses like specific programs...but these are the two big ones that drain you, I think.

I"m recharging now... but basically thats has a fair amount of standby time because with 50 hours, you have two sleep periods "at least" involved.

Usually its just for calls and texting at work with light browsing .... I'll try to remember to spell it out when I get discharged again...... I have posted similiar reports in the past.. but this thread is getting pretty long.

so basically....this battery does work and give you double the battery life..but from what i'm reading.. it just doesn't show accurately on the battery meter? Is that all? I mean I can deal with that until a fix or something is out... jus want to clarify this before I buy one

[forsaken]

in short.... yes double or more even as far as triple. battery left is your answer for the battery meter. im a VERY heavy user, i was only getting 6-10 hrs on my stock battery. i normally get between 26-32 on the seidio.

I would say that I'm a moderate user, running a rooted Droid o/c to 800. Right now I'm running on about 26 hours since my last charge. The only real usage during that time is 30 minutes of phone calls and 1:45 in display time. I can't breakdown the specific usage on the display because DroidMod doesn't list that, but I know that I spent probably 20 minutes on Homerun 3D Baseball, and the rest was general browsing, market use, etc. I also listened to DroidLive and RadioTime for approximately 45 minutes last night (without the display on).

Currently my mv reading is 3805, which according to what windstrings has posted, should give me a decent amount of time left. I usually charge every night, but I'm going to allow it to drain today to give me a good reading on Battery Left.

On that subject, I have a question for preinvent! I am calibrating my usage today and yesterday at work. On my days off, my usage is much heavier. Does Battery Left adjust based on schedules that are drastically different, or will the readings simply be inaccurate on the weekends when my usage is heavier. If I understand correctly, the readings are based on time rather than actual battery consumption...but I may be wrong about that?

[windstrings]

I"m not Matt, but I'll say what I think based on what I"ve read and heard.

The battery left app continues to learn.. even after its calibrated and shows "accurate".. if you drastically change your schedule and that schedule will be a permanent change I believe Matt recommended to fully charge and recalibrate for the quickest resolution of what would be considered "accurate".

However if you schedule bounces around routinely... like you say.. heavier on weekends "or days off" verses weekdays, if its calibrated during the week and then you go into heavy use it will be temporarily inaccurate until it has time to learn and average that use into the equation too.

I would guess that routine will cause it to take an average of each day to give you its best guess since it doesn't have intelligence to know when the weekend is coming up.

I would think once the dust finally settled "in 2 - 3 weeks" you would get an average readout that would continue to fine tune itself over time.

Unless I'm wrong and Matt corrects me.... thats my guess.

I personally put the MV reading as my middle primary readout because regardless of what the percentage says, the battery will never die till it falls below 3400mv or so.... that way I'm not surprised and left with a dead battery away from a charger.

The extended Seidio battery is robust enough that as long as you don't try to do heavy use, you will always be good for several hours as long as the mv reading is above 3600mv.... once it drops below that, things get unstable and you still have several hours "maybe 3 - 5 hours" if you are in standby and only occasional use, but heavy use will drop it on down rather quickly.... "maybe 30 min to an hour before dead"

The readings are based both on time and the system battery level reports. If your schedule changes drastically then it may take a few charge cycles for Battery Left to catch up. The algorithms are designed to take a broad average of your usage and continuously keep an eye on how accurate it is. It adapts over time, but it doesn't keep really old results so depending on how often you charge will probably only keep the last 1-2 weeks or so worth of usage history.

Thanks for the info!

Annoyingly, one of my co-workers wanted to see my phone today and accidently rebooted it. Does this mean I should restart the calibration process again after a full charge, or will Battery Left understand that it was simply a reboot and give me an accurate reading? I saw some mention of this above, but I don't know if a definite answer was ever found.

I'm on hour 30 right now since my charge, but the reboot just happened about an hour ago.

[preinvent]

No need to recal - Battery Left will continue calibration again when your battery level changes (accuracy will read "READING" whilst it's waiting for this to happen).

Great! I get really worried when I'm not sure how much battery life I have, so I was hoping I wouldn't have to do this again for a while.

As annoying as this battery can be, the life on it is nothing short of amazing. It's been running for 37 hours now and is still at 3700mv. I have had about 5 hours of display time, watched about an hour of Youtube, listened to quite a bit of streaming radio, and played probably at least thirty minutes of Homerun 3D Baseball, which is quite draining on the battery. Getting this thing to fully drain is going to be quite a chore.

I used to have an extended battery on my LG EnV Touch and I was lucky to get this much time on it even with barely any use. Something like using the internet for 5 minutes was enough to significantly lower it's power.

One thing I've found about it however, and I think it's been mentioned before, if you don't get a full charge on it, it isn't nearly as great. I charged it for about 5 hours one day this weekend and I only got about 8-9 hours of usage out of it. I was a little worried about the battery, but now I see that it was just a case of it not being fully charged.
