Have you ever experienced a situation where you fully charged your iPhone in the morning, only to find it almost completely drained by the afternoon? Or perhaps you remember your iPhone being fully charged, but when you pick it up, the battery has dropped significantly. In such cases, we might immediately look for the cause on the phone itself.
Actually, besides the phone itself, a bad phone case can also cause the phone's battery to drain faster.Today, we'll help you find the reasons why your phone case drains the battery and explain how to choose a phone case that is better for your device.
Common reasons why iPhone battery draining fast
Software
Background app refresh: Some mobile apps continue to refresh and receive new messages in the background even when not in use. For example, social media apps also constantly refresh and receive new messages in the background. During this refreshing process, the phone's CPU is woken up to process tasks, which consumes battery power. Even though you're not using your phone, the battery is secretly working overtime.
System Update: After a system update, the corresponding files and data on your phone will be rebuilt or optimized. For 1-2 days after the update, your phone may experience slightly faster battery consumption as it needs to adapt to the new system. Once your phone has adapted, battery consumption will return to normal.
High power-consuming applications: Prolonged use of high power-consuming applications can also accelerate battery drain. For example, games and videos drain battery faster because these applications require more network support and place higher demands on the CPU. Over time, this increases battery consumption, resulting in a larger battery usage in a short period.
Hardware
Battery aging: Battery aging is the most common hardware cause of rapid battery drain in mobile phones. Improper use or prolonged use of the phone can lead to battery aging. Simple examples include using the phone while charging, leaving the charger plugged in after the phone is fully charged, always charging when the battery is almost empty, and frequent charging and unplugging. Of course, the lifespan of lithium-ion batteries used in mobile phones will also shorten over time.
Excessive screen brightness: Too high a screen brightness will also increase battery consumption. We can think of a phone screen as a light bulb array; the brighter the screen, the more bulbs need to be lit, and naturally, the more power the phone consumes. When the screen is off, the bulbs are all off, so naturally, no power is consumed.
Frequent network searches: When using a mobile phone, in order to connect to the internet, it needs to constantly update Wi-Fi or cellular data. Frequent network refreshes constantly wake up the CPU to process data, naturally increasing battery consumption.
External environment
High temperature or direct sunlight: Excessively high ambient temperatures will accelerate the phone's power consumption. In high-temperature environments, the chemical reactions of lithium batteries will accelerate, and the internal resistance of the battery will also increase. This means that our phones need to use a larger current to maintain the same operating power, thus accelerating power consumption.
Low temperature environment: Low temperature environment will reduce the battery capacity. In order to maintain its performance, the mobile phone needs more current, so the battery will drop faster. Therefore, in low temperature environment, the battery level displayed by the mobile phone may be less than the actual battery level.
Can a phone case affect a phone battery?
Phone cases can potentially affect a phone's battery life. If we compare a phone to a person and a phone case to clothing, then overly thick or tight clothing can cause the phone to overheat, leading to faster battery drain.
The principle behind this is similar to using a mobile phone in a high-temperature environment. A phone case that is too thick or has a strong seal will prevent the phone from releasing heat in time. To prevent the phone from overheating, the system will reduce the CPU's frequency to process tasks, making the phone's power consumption unstable and causing the battery to drain too quickly.
Some metal phone cases may interfere with the phone's signal, as the phone needs to constantly refresh and update its signal strength to receive more signals. We can see that phone cases can affect battery life directly or indirectly. To find out if your phone case affects the rate at which the battery drains, you can check the following methods.
How to determine if your phone case will speed up battery drain
- The first method is to test the temperature of your phone case. During prolonged use or charging, touch the part of the phone case closest to the phone battery to check if the case gets hot. If the temperature rises significantly, it means that the heat dissipation effect of your phone case is not very good.
- The second method involves comparing usage with and without a phone case. Use the phone with and without a case, using the same software or for the same duration to better illustrate the results. This comparative test will determine whether your phone consumes more battery power when wearing a phone case.
- The third method is check the material and thickness of your SIM card. As mentioned earlier, a thick phone case or a metal phone case can affect the phone's battery drain rate. Therefore, we can also check these two aspects to see if our phone case is accelerating battery consumption.
- The fourth method is wireless charging. Test wireless charging with and without a case to determine if the case affects charging efficiency. If the charging speed is significantly slower or the phone doesn't charge at all, then the case is affecting wireless charging efficiency.
It is important to note that if a single method is insufficient for determination during testing, multiple methods can be combined for confirmation. Also, when using a heavy phone case, avoid conducting charging tests in high-temperature environments.
How to choose a phone case that won't accelerate battery drain.
Material confirmation
Thick or metal phone cases can negatively impact battery life. Therefore, it's best to choose thinner or non-metallic phone cases, such as those made of TPU, silicone, or aramid fiber. These materials are generally thinner and more breathable, preventing excessive battery drain due to thickness. Unlike metal cases, they don't interfere with signal reception, increase CPU workload, or accelerate battery consumption.
Heat dissipation design
While protecting your phone, a phone case should also ensure that heat is dissipated. When purchasing a phone case, you can choose one with a hollowed-out back or ventilation slots to help dissipate heat. Alternatively, you can choose a phone case with a special heat dissipation design to prevent the phone from overheating and draining the battery too quickly.
Functional assistance
Accessibility features can also be considered when choosing a phone case. It should be drop-proof and scratch-resistant, but not too thick to reduce the burden on the phone's heat dissipation. If you want to use wireless charging, choose a phone that supports it, but avoid overly thick wireless charging cases to prevent affecting the phone's signal and heat dissipation.
aulumu phone case
If you're still struggling to choose a phone case, you might want to consider aulumu phone cases.
aulumu's aramid fiber phone case is incredibly thin, only 1.2mm thick, so you don't need to worry about it affecting your phone's heat dissipation. It features an active cooling system with a silicone heat dissipation pad and integrated aluminum plate inside, which conducts heat to the camera frame for cooling. The temperature-sensitive dots on the back change color depending on the temperature.
aulumu also offers TPU phone cases. For lens protection, you can choose aulumu's scratch-resistant frosted case. The TPU material combined with the aluminum alloy lens frame eliminates concerns about heat dissipation or signal reception interference from the aluminum alloy. aulumu conducts signal tests under various conditions before shipping. Test results show little difference in signal reception between using and not using a phone case in different environments.
Of course, if you don't like the lens frame design, you can consider aulumu's rugged outdoor case. This case doesn't have a lens frame; instead, the lens area is raised to protect the camera lens. The four corners are reinforced for drop protection, making it perfectly suitable for outdoor use. There are dedicated ventilation holes for heat dissipation, so you don't have to worry about the phone overheating.
Conclusion
The reason your iPhone battery draining fasts isn't just the phone itself; your iPhone case could also be the culprit. When choosing a phone case for daily use, you should consider its drop protection and heat dissipation capabilities, while also ensuring it protects your iPhone's battery life to guarantee long-term phone usage.
