Battery wear is not linear like a glass of water. My boss' 4s had 86% capacity after many years and 1200?+ cycles. I do not see a problem with a phone having a 95% capacity after 1000 cycles. I believe Apple got a batch of bad batteries that had difficulty maintaining their voltage as the phones aged hence their willingness to do cheap battery replacements to help satisfy these unhappy customers. This is the same thing my wife's 6s+ did (voltage drop). The fact that your phone's performance management was enabled means the battery dipped below acceptable voltage. On an older battery, this capacity difference will widen significantly, especially if a reading is taken further away from a full charge.Īpple's health meter is definitely pre-programmed to take a different approach to reading battery capacity. I've seen a 3-6% capacity difference when reading below a full charge, even more at a 20-40% charge. For consistency I only read at full charge. Battery capacity can vary depending on when you do the reading. Getting an accurate reading on them is difficult, especially over time. Later on, during the battery fiasco that spawned the Battery Health reader in iOS, Apple refunded us $50 without us having to do anything.īatteries are a chemistry. In so doing, they destroyed my wife's 6s+ and we got a new 6s+. They shrugged their shoulders and had to be forced to let me pay them for a new battery out of pocket. We showed them how it shut off below 70% with any load. Of course, when we took it into Apple, they showed "green" and healthy. coconutBattery showed her battery capacity randomly fluctuating between 40%, 60%, and 90%. Less than 6 months into ownership, her phone would randomly shut off and last easily half as long as my identical phone. My wife's 6s+ was the only anomaly in our lineup of phones from the 6+ to the Xs MAX. Most of my other phones strayed a percentage or two (6+ and 8+) - this includes iPads. The worst was my 6+ that went from 108% from design capacity to 98% after almost 2 years. I'm a light user and my wife is a heavy user of her phone.Īfter 2 years and 230 - 300 cycles my phones have had little to no battery degradation in terms of overall capacity. My wife gets the same phone I do so I have 2 phones to "observe" and compare against with very different usage. I usually keep my phones for 1.5-2 years. I take weekly readings and focus on the battery capacity vs design capacity. I have watched all of my devices with coconutBattery since the 6+, to the 6s+, to the 8+, and now Xs MAX. As a self prescribed battery hobbyist, I must admit I'm not entirely sure what is going on. Thanks to its simple and intuitive user interface, even most inexperienced users will find their way around the app quite easily.I don't think either are lying. User friendly battery health tracker with export and import optionsĪdditionally, coconutBattery offers you the possibility to backup the readings by exporting them to CSV or archive files: this way you will be able to preserve the information even if you reinstall your system.Īlso noteworthy is that coconutBattery can import only archive files: you can use the CSVs for sharing purposes, but you must generate an archive to be able to import the data.ĬoconutBattery provides basic tools for reading the current status of your notebook’s battery and is able to save the logs separately. Moreover, you can see the manufacture date, the number of load cycles, the OSX Battery status, and the battery temperature / usage level / state.Īll this information and the fact that you can save the readings as historical log files, give you the possibility to see how the battery health deprecates in time. Extensive information about the battery's current statusĬoconutBattery displays data about the current battery charge, the maximum possible charge at the time, but also the initial capacity for the battery design. Provides you with detailed information about your Mac's battery via a minimalist user interfaceĬoconutBattery comes with a small window that is separated in two tabs: summary (here you can view details about the battery’s current status) and history (allows you to browse the available logs).īesides information related to the battery health, coconutBattery is also able to provide details about the Mac model you are using, the manufacture date, the age in days, the serial number, and the currently installed operating system. coconutBattery is a small but very useful Mac app that analyses the current status of your battery and keeps historical logs. Your Apple notebook’s battery looses its health in time, so tracking the battery health level is a good idea if you do not want to be caught by surprise.
