AccuBattery

Search This thread
Could you try to charge your phone from 0 too 100% and see what AccuBattery says then? :)

Short term AccuBattery use is not an accurate measurement of battery capacity. You need at least a month worth of charge logs to get anywhere near an accurate reading from AccuBattery.

I just charged my Rog Phone 2 (received it 3 days ago) from 0% to 100% with a USB Power Meter inline on the charging cable (which is the best and most accurate method of testing battery capacity), and it took exactly 6,105mAh to fill the battery.

I know that ;) As i wrote, I just wanted to see for fun

Here is my Ab measurements. Will test with a USB-meter later to see if it is really accurate. I hope not ?

I'm seeing very similar results to you, I tested with a USB meter but it's hard to guess how efficient the charging process is.

Yeah, but I see you haven't charged your phone from 0 to 100%. Please try that and see (remember to let it charge fully after 100%, until you see the current reach 0mA)

I have done but only with the phone turned off to get a more accurate figure. I don't think it's that important for AB, especially considering my results are almost identical to what other users have reported.

I see people in this thread using USB power meters, saying things like "it took exactly 6,105mAh to fill the battery" but there are no maths explaining how they got to this figure. You can't just take the reading from the USB power meter as that is charging at 5V or 9V which is different to how the batteries capacity is rated. Ideally we should be using mWh as it makes these things easier.

When I charged mine 0 - 100% with the device off, I got 27.4Wh from the power meter, the battery is rated at 23.1Wh so taking a guess at 15% for efficiency losses and you get 23.4Wh charged.

You need to have the phone turned on with AccuBattery running for it to measure ?

Estimated capacity is going down pretty fast.. (was around 5600mah when I got the phone) Also measuring only around 5080mah with a USB-meter.. The battery-% on this phone is very unstable. Anyone else with the same experience?

    Hello!

    Has anyone tested the battery-capacity with AccuBattery? I know it isn't always that "accurate," but I want just to see for fun :silly:

    Yes, it shows me 5,579 mAh... based on 9 sessions with 542% charged for 30,236 mAh total.
