How to determine actual battery capacity?

WarAxe · #1 (**permalink**) 03-17-2009, 11:19 AM

I have installed the nue utilities and drivers, and I can monitor my voltage, charges rate, and discharge rate.

But, is there a program that will record my battery voltage over a full discharge, and also measure my discharge rate to determine actual battery capacity during the full discharge?

I remember seeing something (someone correct me if I'm speaking out of turn here) in Juicy/JMZ 4.5.5 (now 4.6) that showed total charge, duration of charge, uptime between charges or something to that effect. Not sure if that only appears in that rom or somewhere else but that might fill the need

try ariel battery (its also a battery icon and when u click it, it gives u estimated battery time left) (except im not sure how accurate it is, hav'nt tested it out lol)

I think I found what I was looking for:

UPDATE: This app is buggy and crashes after a few minutes

spb benchmark has a power option. I've never used it, but I think it takes your battery from full to zero, and then gives you a report. I'm just not that patient.

nuePower CPL is quite nice also. but it doesn't do a benchmark. Shows discharge rate, charging rate and so forth.

Open the back cover, and read what it says infront of the mAh, then take the current discharge # and divide it.

battery mAh rating
--------------------------- = Hours.
current discharge mA

If your wanting your Battery Capacity the most exact way is to fully charge your phone. Turn off any power saving and low battery alarm/shutdown, and turn on battery monitor. With nothing in the background running this discharge # should be constant. Record how long it takes before it dies, then multiply it by the discharge rate and it will give you your battery capacity.

That's true... the discharge rate should be constant-ish and I could probably get a decent measure from it.

I may also try Groove's suggestion of SPB Benchmark.
