While charging and on battery with about +70% i measure a battery voltage of 4200 mvolt = 4.2 volt, sometimes even 4300 mVolt. The sticker on the battery says it is a 3.8V battery. Is this normal behaviour?
Have you ever looked at NiCd or NiMH batts? They list them as 1.2 v, but they will show over 1.5 v when fully charged and will be actually discharged at 1.2 v (with no load), so yes it's all just about right, I'm showing about 4v at 80%
I pit the Motorola Turbo Charger against one of my other 2A charger, a Trent NT90c
I set to charge from 15% to 100%. Screen off, turning on every 5 minutes to check percentage. Didn't turn off anything else as I want to test this as normal as possible.

Turbo Charger is able to supply at least 6% of charge for at least 45minutes, then it slows down to 4% per 5minutes until it's fully charged. That last 2% charge did take a lot longer though.
Trent charger is pretty much constant at 4% per 5 minutes, then down to 3% increase after it got to 92% charged.
I'll try a 1A charger next, lol I also have a Nexus 10 charger to try as well. I dont have a 3A charger to test.
Awesome info. Just curious why you start from 5%?

That's what the phone was at at the time I thought about doing it.
it's probably an 8%-10% increase per 5mins for the first 15mins for the Turbo Charger.
i'll do another this weekend.
Test 2 from almost depleted 1% battery.

Hey can you update it again as mine is taking 90-100 mins to chagre with the tubro charger itself.
Thanks
How hot does the battery get when you are turbo charging it? IIRC, hotter batteries = shorter battery life overall.
what happen to 15 min 60% charge lol.
my battery gets pretty hot/warm when charging.
I think it was 6 hours of usage (overall, not 6 hours of gaming) in 15 min. And with my battery lasting 36+ hours, that 23% would def get me 6 hours.

yours is about the same. mine charged in 93mins w/ the Turbo Charger. I dont think 3-7 mins is that much of a difference.
Now that I've added a few more apps tho, it might be a lil more. I'll try time it again.

Thanks a lot man. Will keep waiting for it

Also tried an Anker 60W 6port USB charger.
It has Power IQ where it's supposed to adjust charging power to what the device requires. I think it's supposed to max out between 2a - 2.4a
Well, from completely drained out battery, it took a full 3hrs to fully charge the device.
If you want your device charged fast, don't get this charger.
If you have time to wait and a lot of devices to charge all at once and like to travel, get this device.
Has anyone monitored the voltage/current output of their turbo charger? I cannot get to the "turbo 2" output (12 V, 1.2 A) listed on the charger. Even from 4% battery, I max out ~ 9 V, 1.5 A, which is listed as "turbo 1". In my test today, charging was pretty constant around 1.3% per minute up to 60%, then dropped off as expected. Some more data: starting at 4%, here are the total times (in minutes) to critical percentages.

I haven't seen it use the 12V output yet. Its not s large difference 13.5 W for turbo and 14.4 W for 12V. I wonder how much faster it would charge and if it's a software or hardware limitation

Waiting for it
What app r u using to see the current output?? Ill check mine too
I personally found that the stock cable that comes with the phone doesn't allow for that much voltage/amperage to pass through it. I do have another cable at home that is thicker and it charges it a whole lot faster. I will try and get the data for it.
So what's the best cable and wall plug for fastest charging?

18 watts?
I am getting similar results as the OP. It works out to about 2400maH, which is about 75% charge in one hour. This is theoretically about the same as you would get from a 5v 2.4A (12w) amp non-turbo charger, which I have achieved with my "Note 3" 2.4A standard charger. One would think the turbo charger would charge about 50% faster on the Nexus 6 either at 9v 2A, or 12v 1.5A, which is 18w, which I haven't heard of anyone achieving.

For some reason, I don't trust those turbo chargers. I think I'll stay with a regular 2.1A charger. It doesn't charge real fast, but I have time and it may be safer for the battery.
My charging rate
What are your true battery capacity? Has anyone run the full battery charge cycle through mAh meter? My phone was in transit for a whopping 2.5 months. It arrived with 0% battery, fully drained. It charged OK, but battery seemed too weak. I did charge it couple of times, then after a full discharge (to 0%, and shut-off) I charged it to 100% through mAh meter, and it only showed that battery took in 2232 mAh instead of factory capacity of 3100 mAh. I'm afraid that the battery has really degraded while being at 0% in winter cold (mild but sub-zero temperatures here in Canada). Or is it just because it's new and will improve after several cycles? Not sure how accurate is the mAh meter, or whether it's the right way to test. I've also installed AccuBattery, will see what it reports, but I'm not optimistic. With another phone I'd replace the battery, but you need a heat gun to open this one, it's a huge mess with a chance to kill it... So any feedback on your batteries or tests? How can I really verify that the battery is within factory specs?
Drain the battery to 0%, then use a 5v/1a charger to charge the device. Verify with an app that the phone is craging at 5v/1a, then switch off device and measure exactly how long it takes to charge to 100%. Then use this equation
Q(mAh) = 1000 × E(Wh) / V(V)
simple version:
mah = 1000 x (5 x hours charging) / 5
Then we can establish true battery capacity
I have solved this issue. Turns out that with fast charging my USB meter was giving inaccurate results. I used another charger that was not engaging fast charging, then USB meter showed normal capacity, which was almost exactly 3100 mAh stated.

How are you finding the battery life? Can it always get you thought a full day?
Yes. I'm not a very aggressive user. Occasional use gets me to about 40% to 60% by the end of the day. Most people will use phone more.
hi guys, as a heavy user as i am i have 6,5 hours of SOT, so it should be enough for a heavy day use.

i forget to mention im on the AOKP ROM
I have been using my phone since 13 July and have been using AccuBattery right from the start. Been charging my phone to 80% amd not to full. Yet the battery capacity is 92% right FROM THE START. I dont think my battery was already 10% degraded right from the start.
What is the stats for other people who are using AccuBattery on their OP5?
What may be causing the discrepancy? Kindly help.
I have the same. Charged from 1% to 100% and above (till charge current went to 0 mAh) and the capacity seems to be 3100 mAh instead of 3300 mAh.
Another thread about AccuBattery crap.
I recently bought a used Huawei Nexus 6P on Swappa. It looks and works great, with one exception: When I quick-charged it (with its OEM quick charger) to 100%, AccuBattery reported:
Battery health: 27%
Estimated capacity: 940 mAh
Design capacity: 3,450 mAh
{From these numbers, it seems that Battery health = Estimated capacity / Design capacity}
By itself, that would make me think that it just needs a new battery. However, if after reaching 100% charge, I leave it plugged in, the "Estimated capacity" continues to rise for a period of time. (The charge stays at 100%, but the Battery health sometimes increases.) Once, the "Estimated capacity" rose to over 2,000 mAh before it stopped rising. This makes me think that the problem might be with the battery calibration, rather than with the battery itself.
If I use the phone until it shuts off, and then recharge it, the same thing happens again (although with different numbers).
How can I tell whether the problem is with the battery itself, the battery calibration, or the phone's charging system (on the motherboard?)?
To recalibrate the battery, should I stop charging it when it reaches 100%, or when its AccuBattery reported Estimated capacity stops rising, or ...?
Thanks.
