Hi,

A week after getting X I checked capacity with Coconut battery app and here are the stats:

design capacity 2701 mah

full charge capacity: 2763 mah

cycle count: 5

Are these numbers in line with general decline of lithium batteries? I am asking because:

iphone 6 753 cycle count and 91% of design capactity (1647mah/1810mah)
iphone 6s plus with 188 cycle count is at 94% design capacity (2585/2750 mah)

my 2011 Macbook pro 13" wtih 403 cycles is at 80.9% deisgn capacity whereas my Macbook 2015"(august 2015) is at 65.3% design capcacity after 302 cycles.

Or is coconut battery app not accurate?

Design capacity is what it should have. You have 62 more. It’s going to explode..not

Use and enjoy your phone. Don’t get hung up watching apps like Coconut battery all the time. I seriously doubt you have lost any real battery life in a week.

Battery discharge and charge is not on a level plane. As such, you will have readings that differ from hour to hour and day to day.

Before I go into a huge battery post again.... BasicGreatGuy is 100% correct. Turn off the battery % reader on your phone, try to enjoy your phone. The readings are not consistent (it is normal to have a little fluctuation).



It is normal for design capacity to fluctuate. Take it from someone who monitors coconutBattery religiously and writes everything down into an excel file for my 6+, 6s+, and my 8+.

http://batteryuniversity.com/ -- great place for battery OCD people like myself. He has a great book as well - I highly recommend it. I've read it a handful of times. http://www.amazon.com/Batteries-Portable-World-Rechargeable-Non-Engineers/dp/0968211844/

Lithium Ion batteries fluctuate. But, they should actually grow a little in overall design capacity at first, after the first 100 cycles or so, then start a downward trend, depending on use, over the next 200-300 with an overall life cycle of 500 cycles and still retain 80% of design capacity.

My 6+ had 95.60% design capacity after 235 cycles but started out at 96% out of box. My 6+ started out at 106% design capacity out of box and after 240+ cycles had 97% capacity.

Pointers:
Only read the design capacity after a full charge (where it stops charging - this can take a long time to get to this point). Keep the phone from getting super hot. Keep the phone above 20% if you can help it. Doing trickle charging from 85%-100% is better for your phone than draining down to 40% and back up to 100%.

Mine came with 2803 mah as full charge capacity when I first got it. Currently reads that i'm already at 3 cycle count and still at 2803 mah full charge capacity.

I’ve had mine since release day and my battery is still at 100% capacity.

Have you been in extreme temperatures?

I have not been using it as my primary phone until today. Just swapped sim cards from 6s+. I have been using it on wi-fi at home mostly.

Sounds like the X was launched prematurely based on the problems I’m reading about it. Glad I got the 8 plus. Lots of issues with the X I see. Hopefully they will get fixed soon.

Me: with battery percentage visible on home screen = charging my phone as soon as it gets below 90%.

Me: without battery percentage visible on home screen = charging my phone when ever I see the icon maybe around 50%.

Me = much happier without thinking about battery life except once or twice a day now versus monitoring it like a hawk.

Also, I am only going to have the phone for a year so absolutely unconcerned with any battery cell capacity loss over that year.

X Already lost 62maH capacity in a week?

That is an issue.

Stop trying to make this an issue. There is basically no info in the OP's post. Certainly nothing concrete or scientific. In fact looking at their post it looks like the phone at full charge is GREATER than the design capacity for the phone, so they are getting more battery power not less.

Use your brain and stop trying to find trivial things to be outraged over.
