Over time, iPhones experience battery degradation, especially models like the iPhone 11 128GB. Eventually, you'll need to replace the battery to maintain optimal iPhone performance. But what if your iPhone battery is draining fast, and you can't replace it immediately? Here's what to do when your iPhone battery is drained.
Essential Steps When Dealing with a Drained iPhone Battery
1. Common Causes of iPhone Battery Drain
Various factors can contribute to the rapid depletion of an iPhone's battery, whether it's an older model like the iPhone 11 series or the premium iPhone 13, iPhone 14 Pro Max, or even the iPhone 15 Pro Max. Here are some common reasons iPhone users encounter:
1.1. Using Low-Quality, Non-Official Chargers
Many users inadvertently misplace their original chargers and opt for cheaper alternatives of unknown origin. Choosing low-quality chargers prolongs the charging process and accelerates iPhone battery depletion.

1.2. Habitually Draining the Battery Completely
Many users have a habit of using their phones until the battery is completely drained before charging. However, if you start charging your iPhone below 10%, part of the battery undergoes chemical reactions, causing the energy cells within the battery to diminish. Lower energy levels mean less battery accumulation, resulting in shorter usage time. That's when the iPhone battery starts to deplete.

1.3. Simultaneous Use and Charging of iPhone for Extended Periods
Daily life is busy, so people often rely heavily on their phones to manage their tasks. Consequently, many individuals tend to use their phones while they are charging. Although it's possible to use the phone while charging, prolonged usage in this manner can cause the device to heat up more quickly. As a result, the battery lifespan decreases, and the battery drains faster.

2. What to Do When Your iPhone Battery Drains Quickly
If your iPhone battery is draining quickly but you can't get it replaced immediately for some reason, you can perform the following actions as temporary solutions:
2.1. Activate Low Power Mode
Low Power Mode is a special feature designed to extend iPhone usage time by limiting certain functions. Specifically, when Low Power Mode is activated, some features are disabled, including: screen brightness, automatic downloads, background app refresh, maximum screen refresh rate of 60Hz, and iCloud Photos temporarily paused.
If you find these features unnecessary, you can activate Low Power Mode by going to Settings, selecting Battery, and sliding the Low Power Mode toggle to the on position.

- Step 1: Open the Shortcuts app and select Automation.
- Step 2: Tap the “+” button in the top right corner and select Create Personal Automation.
- Step 3: Scroll down and choose Low Power Mode.
- Step 4: Deselect Is Turned On and select Is Turned Off. Then you need to press Next.
- Step 5: Press Add Actions.
- Step 6: Press the search box and type Set Low Power Mode to select the command below.
- Step 7: When the Turn and On options turn blue, continue by pressing Next.
- Step 8: Turn off Ask Before Running and select Don't Ask.
- Step 9: Press Done to complete the automation setup process.

Set Low Power Mode to always be on in the Shortcuts app
Now you can toggle Low Power Mode on/off anytime. However, to disable this feature, you need to go to Shortcuts and turn off the Enable This Automation switch.
2.2. Develop More Scientific Phone Usage Habits
- Adjust the screen brightness to a sufficient level and only turn it on when absolutely necessary. Additionally, enable night mode to save battery power.
- Charge your iPhone when it reaches 20%. Avoid waiting until the battery is completely drained before charging your device.
- Limit overnight charging of your iPhone, as this helps prevent battery depletion and ensures safety.
- If it's not urgent, avoid using your phone while charging.
Note that the suggestions above are only temporary solutions. If your iPhone battery deteriorates significantly, you need to replace it to restore the battery's original performance. Moreover, replacing the battery also provides you with peace of mind during usage. When replacing your iPhone battery, it's advisable to send your device to the manufacturer to receive genuine batteries, ensuring quality.
