There’s one thing we can state as a fact for an iPhone, that it’s battery tracker is not reliable. This belief is shared by users on popular technology forums, some of whom have reported scenarios where their batteries dropped from 20% to 0% in 2 minutes or stayed at 100% for 2 hours before dropping to a surprising 85%. Other users have reported super-fast battery charging that they can’t explain. (10% to 30% in 1 min, anyone?)
The battery issue has been igniting debate for some years now. In January 2016, Apple confirmed that the battery meters for the iPhone 6S and iPhone 6S Plus models were experiencing a bug triggered by manual changes to the ‘date and time settings’ phone feature.
The company noted that the bug was affecting the way the battery meter would display, with higher percentages being shown despite having little battery left. Other iPhone users, some of them with new devices, were also experiencing sudden shutdowns and low battery percentage displays even after achieving full charge.
Apple replied swiftly and, in the wake of the events, it revealed that it was working on a permanent fix to the battery meter issue. That was 2016. Considering that it’s nearly 2018 and the battery meter is still misleading users. We can be sure that the solution definitely hasn’t arrived yet.
If you’ve experienced a sudden shutdown while using your iPhone, you know how interfering it can be for work or leisure. But why does it happen? Did Apple forget its batteries when rethinking – and ultimately designing – the wonder that is the iPhone?
It’s a technical issue…….probably!
The iPhone, like any other phone, uses its iOS to gauge the battery used, basing on the actions the phone has taken(say, streaming videos , connecting to WI-FI or making calls), its current environment (whether hot or cold) and how long it’s been in use. The battery meter displays what the iOS measures as remaining battery at the top of the screen.
But unlike many other phone models, the iPhone battery tends to report battery dips much later than they occur. One estimate shows that the iPhone will display 100% when the battery is really 95%, display 50% when the actual battery us 47.5%, and so on. In other words, battery dips do happen, but the iPhone takes longer time to acknowledge them for display.
What theories define?
There are different theories as to why the iPhone’s battery meter still plays with you. One suggests that the older a battery gets, the higher the chances that it will report different battery readings from the actual ones. Another takes a different approach, pointing the finger at the measurement system used by the battery to monitor charge.
Apparently, some manufacturers design their batteries to measure existing charge based on the current voltage, while others measure the amount of charge flowing through a battery over time to determine how much battery’s been used. The final theory suggests that there is a slight delay or disconnection between the software, the battery meter and the battery, resulting in displays of wrong readings.
Either way, the battery meter is never fully accurate, even in other phone models. The value displayed on the screen is always, at best, a near estimate.
What you can do?
On some tech forums, some users report that they finally fixed their battery meter issues with a few simple tricks. Some users maintain that no trick has yet solved their issue and that their battery meters still give them a great deal of trouble.
There are a couple of things you can do to better this situation too. One of them is recalibrating your iPhone battery, a method many forum users said had worked as promised. Recalibration involves draining your phone’s existing battery until it shuts down, charging it to 100% (plus two more hours of charge after it clocks 100%) and restarting it with the ‘warm restart’. The whole process is done twice.
Remember: This might, or might not work for you.
You can also check for software updates if you haven’t done so in a long time. Apple releases regular software updates, some of which are targeted toward battery longevity and performance. As part of its response following the January 2016 battery issue, Apple released a software update that fixed the bug for users. The company had promised more updates in the future, with emphasis on the battery issue.
If all are lost and your battery meter is going out of hand, consider taking your iPhone over to the nearest Apple store for a check-up. If your battery is found to have a problem, you could always get a new one and start anew.
