Is this mv normal on my extended battery? - EVO 4G Q&A, Help & Troubleshooting

3697mv is shown at 15% on Battery Calibrator. I already let it drain and then let it charge for 8 hours. Now I'm draining my extended from 100% for the first time.

Extended battery fail

Bought the extended battery from verizon, installed it, charged it and now my battery is dropping about 1% a minute. What the hell?

Those and most extended batteries suggest up to 5 charging cycles before you see better results. Give it some time.
Yeah just wait and let it settle for a week...it's too early to assess results on first full charge..

Confused

Does this mean my display has used 84% of my battery. Its been off the whole night.

No, your battery is still at 97% so out of the 3% consumed, 84% of that 3% was used by the screen. Those percentages represent which apps have used the amount of battery used since off charger. Savvy?

Still having battery issues. Ext. Battery....

Im using the HTC Evo extended battery. Li-ion 3.7v 3500 mAh battery. The problem is no matter how i try to calibrate it whether using hipkats methods or other methods it WILL NOT measure the full capacity. It never measures more than 1800 mAh. Right now its at 1589 mAh measured with 4233 mV as my max voltage. What is the max possible voltage for this battery? And is there any way at all to get the phone to measure the full 3500 mAh or even close to it? If so please tell me how.

You will not be able to charge any Li battery much more than 4.233 volts or 4.3V tops. Not sure about the methods.
Perhaps you need to reset the app or go into recovery and reset the battery stats.
Like "conductive" said. Go into recovery and wipe battery stats like 3 times. I think the battery must be full before doing it. Wait till it drains out and charge it back to full. Then check again.

Ive done that. That's part of the calibration process. Ive wiped at full charge, let it drain until it shut off from low battery and fully charged without the phone being turned on.

Nothing fixes it or even makes it register the full capacity of the battery...

Decent Extended Battery in India?

I need a decent extended battery that could last about 24 hours with proper usage. Is something like this possible in India?

Don't know about battery but there is a extended battery cover. The cover has an battery inbuilt so when your phone dies or is about to die just switch on the button on the cover and the battery gets charging
Hope this is something you are looking for

Can you share the link?
Buy a 3400 mah battery from ebay.com, mine lasts avg 36 to 48 hrs with my usage, yours will vary.

Weird battery stats

So I have the anker 4400 extended battery and for some reason every time I charge it to 100. It works as normal but when it hits 90 percent it resets the stats. Does anyone have a solution for this ? I'm on the hyperdrive ROM.
