Why does my iPhone battery drain so quickly after an iOS update?
Why does my iPhone battery drain so quickly after an iOS update? You might have expected a performance boost when you performed the new iOS update. How would you feel if things didn’t occur the way they are supposed to? Especially when it comes to the faster battery drain. The frustration you feel when the iPhone battery percentage drops even with minimal usage is unexplainable. Your anxiety must be at its peak when you think over battery health and potential repair costs. This blog provides you with insights into why your iPhone battery drains so quickly after an iOS update and ways to manage it. What Happens After an iOS update We understand your worries regarding the changes that have happened to your iPhone battery performance. Let’s first understand what happens after an iOS update: Your system runs background processes to complete installation tasks. As part of optimising the performance, the apps re-index data like photos, messages, and files. System settings revert to default configurations. New features will start to activate and start to consume power. iOS recalibrates the battery and performance metrics. Apps update compatibility settings in the background. Network syncing increases for iCloud, mail, and backups. A temporary increase in CPU load causes faster battery drain. Main Reasons iPhone Battery Drains After an Update Background Process Still Running The iOS update targets system optimisation and aims to ensure that your iPhone continuously runs several background processes to complete the system optimisation. The process, such as indexing files, organising data, and finalising installations, temporarily increases the CPU usage. All these can cause faster battery drain. System Recalibration Battery calibration may cause the battery percentage to drop following an update. This happens because iOS recalibrates battery performance metrics to accurately measure usage and health. Your battery will function normally. Even though you can find the battery percentage drops more quickly than usual during this period. New Features and Settings You need to manually adjust the features of your iPhone after an iOS update. After the update, you can expect additional features such as enhanced location services, live widgets, animations, and background refresh. All these can continuously consume power. This iPhone battery drain can be solved to a large extent by adjusting the features of your device after the update. App Behaviour After Update After an iOS update, the apps must adapt to it to ensure compatibility. As part of this, many apps run background updates to improve compatibility. This increases the CPU and battery usage. Some apps may not be fully optimised immediately after the update. Apps may resync data such as messages, photos, and cloud content, which consumes additional power. All these can contribute to abnormal battery consumption. Network & Syncing Activity You can expect an increase in network activity after the update. This is to be utilised for syncing iCloud data, emails, backups, and app content. Continuous background syncing places a heavy demand on the battery. This may be worse if your mobile is connected to mobile data or weak networks. How Long Does the Battery Drain Last? Your battery drain can be expected to last 24 to 72 hours. The drain mainly happens when your system completes background optimisation tasks. During this period, iOS recalibrates battery performance, indexes data, and stabilises new features. The duration of battery drain may extend if your device has a large number of apps that require optimisation. Older iPhone models may have hardware limitations, so it will take more time for stabilisation. Once all the background processes finish and apps update, you can expect improvement in battery performance. If the drain continues for more than a day, it signals app issues and settings changes. Escalation of the matter may require a diagnosis from an iPhone repair centre in Dubai. How to Check Battery Usage You can use the battery usage data to decide whether to update, limit, or remove battery-draining apps. Let’s check the steps. Go to the “Settings”. Tap on “Battery”. Check the “Battery Usage by App” section. Check “Last 24 Hours” and “Last 10 Days” and compare the usage. Review “Background Activity”. Check “Home & Lock Screen” or “System Services”. Practical Steps to Improve Battery Life Even though the battery drain happens for sure for a certain duration after an iOS update, you can optimise it through certain activities. Firstly, check on the outdated apps. It may run inefficient background processes that cause battery drain. So regularly update apps from the App Store. It ensures the bugs are fixed, performance is improved, and power efficiency is enhanced. Apple’s low power mode is a battery-saving feature that reduces battery consumption by limiting background activities, visual effects, and automatic downloads. When it comes to non-essential apps, you can disable the Background App Refresh. This can help prevent unnecessary processing and reduce CPU usage. As the biggest battery consumer, the display consumes noticeable battery power. So during the post-update adjustment phase, lower screen brightness, enable auto-brightness, and reduce screen timeout. Limit widgets and animations to improve overall device efficiency. You can disable motion effects, remove unnecessary widgets, and reduce animations through accessibility settings. Conclusion When an iOS update occurs, the first thing that comes to your mind is improved performance. However, the sudden changes in the software can adversely affect the battery, causing it to drain fast. This issue will last for a certain duration and solve itself on its own. If it didn’t, it’s better to consult a service centre for iPhone battery replacement in Dubai. Struggling with a persistent battery drain after an iOS update?
