How to Tell if You Need a New iPhone Battery

by birtanpublished on November 26, 2020

It wasn't that long ago December 2017 that Apple admitted it was indeed slowing down iPhones overtime on purpose ostensibly this was to make sure you didn't want to throw your iPhone against a wall after an OS upgrade because the batteries inside were becoming a real drag on the performance and sometimes causing unexpected shutdowns Apple throttled the battery output to the CPU down on older iPhones so that the battery would last a little longer and shutdowns would cease the slowdown in performance was discovered when replacing a battery put older iPhones back to full performance which would

Have been a good thing if the general public had been told about it up front in response to that kerfuffle Apple ordered $29 replacement batteries for select older iPhone models throughout 2018 however Apple did not stop throttling older iPhones the difference is it'll actually tell you about it now and by tell I mean you can go looking for the info in your iPhone's battery settings is your iPhone's battery capacity bad enough that it needs a replacement that could be a scary process for your expensive lifeline to all connectivity especially if you're

Quarantined at home and it isn't cheap it costs $49 for older iPhones or $69 for the X X s XR and 11 models if you go through Apple it could mean relinquishing your iPhone for days Apple stores could do it during a lunch hour but who knows when they'll reopen same likely goes for any third-party Fixit shop if you do go to one make sure they wash their hands or do it yourself I fix it sells iPhone battery kits including tools for $29.99 for iPhone 8 made plus with more expensive options for the X X R and X X max before you decide make sure to dig into the data about

Your iPhone's battery to determine if the replacement is even warranted rest assured if you hang on to your iPhone long enough it will be warranted eventually beware of performance management in iOS 11.3 released in March 2018 Apple added battery health in order to save face amidst legal battles related to better eventually Apple agreed to pay everyone affected by it $25 each part of a class-action lawsuit total cost to Apple in the end will be between 310 and 500 million dollars the battery health option exists to provide the smallest

Modicum of transparency about the capacity of an iPhone's battery and if I OS is crippling iPhone performance supposedly iOS will only throttle the power to the CPU if your battery is below 100% capacity and it has one expected shutdown in iOS 11.3 or later go to settings and in battery at the bottom Apple now includes lovely bar graphs showing your iPhone battery charge levels and screen activity over the last 24 hours or 10 days you can also see the full battery usage per app that's a nice way to determine if some app is in the

Background sucking up all the juice but mostly it's a bad activity time you can toggle back and forth between activity and battery usage above those tap battery health this is the area of importance next to maximum capacity is a percentage of how much your battery can currently hold in comparison to when it was brand new the lower it is the worse things are for all the lithium ion inside holding the power peak performance capability is the one to watch it might say your battery is currently supporting normal peak performance that means it is as daddy

Used to say in Star Trek functioning with normal parameters however it might say this iPhone has experienced an unexpected shutdown because the battery was unable to deliver the necessary peak power performance management has been applied to help prevent this from happening again that last bit is a flowery way of saying we throttle the power to your CPU for your own good thankfully the option should be right there for you to disable performance management be aware that if the phone has another unexpected shutdown that the iOS blames on the weak

Battery getting sucked hard by the CPU it'll apply performance management throttling all over again you may also see a message that says your iPhone batteries health can't be determined or that it is so sufficiently degraded that now is the time for you to replace it that generally won't happen until the maximum capacity is lower than 80% after 500 complete charging cycles read more about that in our story about battery myths with the iOS 11.3 update Apple locked apps out of looking at the battery capacity or charge cycle number way to keep it transparent Cupertino

However for more details on what's happening inside the iPhone download an app like Liam device info Lite it doesn't look at battery info but does chart the ups and downs of your iPhones chip performance under this device than CPU and CPU actual clock you'll be able to see performance changes in real time if you want to do any of this on your iPad or even the iPod touch you can't battery health is only available on iPhones because Apple isn't throttling iPads and the iPod touch however the charts displaying charge levels and screen activity are available

If you're interested in counting exactly how many charge cycles your iPhone or iPad or iPod Touch have been through that's not easy to find but there are desktop apps that can help coconut battery 3 for Mac OS or the $35 I backup bot for Windows can pull data from the I device connected to a PC and display the cycle count number among other data and anything over 500 charges your iPhone battery has seen better days for iPad the numbers more like a thousand cycles it has a bigger battery so what's the criteria for getting a new battery certainly consider it if you see the

Performance management kick in who often or the lehre device info app displays a significant downgrade in the CPU actual clock number definitely upgrade if the iPhones own peak performance capability says your battery health is significantly downgraded if you're brave and or cheap get the iFixit battery replacement kit option otherwise you may have to live with the problem until the 2020 quarantine comes to an end or until you mail order your next complete iPhone upgrade
