Hi just installed ios11.3
I checked the mac capacity of my battery,since the iphone x is only two months old i expected a 100/100.
I saw 99 instead...is this normal?i think itis too early for the battery to start loosing its capacity
Sounds pretty normal to me. There are a lot of little variables. One of them is that there might be a standard deviation for original capacity due to manufacturing variations.
Apple rates the battery at 500 complete charge-discharge cycles before a typical reduction in battery health to 80%. So if it's an average 250 cycles per year, a linear degradation would be expected to mean a reduction to 90% in one year. 99% doesn't sound like there's a problem.
Also - it's important to understand that the battery health number is just an estimate.
Mine is only a year old and it shows 89%. Is this normal?
Battery readouts can be confusing with phones. Anything between 95% and 100% are considered normal. You could for example, charge a phone to 100%, take it off the charger and find it reads a lower figure. That could be because of the background apps like mail and location begin to absorb power immediately, as too could be the brightness setting.
I don't know if iPhone X supports fast charging, but in general its an unwritten rule not to use chargers with more amps than the regular one of the phone. Using lower amps is fine though, like charging from an laptop/desktop USB.
With many people’s normal usage a typical smart phone or tablet battery may well lose up to 1% capacity per month. That’s not necessarily excessive at all. Most such batteries, used daily, will only last (in terms of expected average lifespan of ~80% capacity after 500 full discharge/charge cycles) 2 to 3 years, at which point they will typically retain less than ~80% of original capacity.
Also note that the software readout is an approximation - it’s impossible to precisely determine capacity at any given time so if you insist on monitoring it frequently you’re inherently going to get fluctuating results (they will vary by temperature and humidity, recent power draw or charging, etc).
Heavier usage, and thus more frequent full cycle equivalents over time, will degrade them even faster. Note too that lithium batteries degrade whether used or not - even if never used, their useful lifespan is finite as capacity will decline as the battery auto-oxidizes internally and the electrolyte degrades.
