Your iPhone has a “Low Power Mode”, which you’ll be prompted to activate it when your phone reaches 20% battery. You can also enable it before that point to stretch your battery life further.
Low Power Mode disables settings like mail fetch, Hey Siri, and other things that people commonly change when they want to make their iPhones live longer between charges. For whatever reason, Low Power Mode is only available on iPhones, not iPads. Starting with iOS 11, you can also enable Low Power Mode right from the Control Center.
If your device is jailbroken, you can even automate Low Power Mode. It helps you ensure your battery never dips to critical levels while out and about.
When enabled, smokin1337’s SmartLPM automatically turns on Low Power Mode when your iPhone’s locked and not in use to reduce workload and keep battery drain to a minimum. The tweak can be further customized to make this kick in exactly when you want it to.
SmartLPM has lots of benefits to offer your jailbroken device, with doing away with the need to manually enable Low Power Mode in critical moments being chief among them. Most important of all, automating the feature goes a long way towards preventing your iPhone’s battery from degrading over time. It will lessen the need to constantly charge it due to excessive battery drain.
What Low Power Mode Does?
Low Power Mode does a number of things to save battery power. It automatically changes some settings to save battery power. For example it disables automatic fetching of new mail, reduces your screen brightness, and automatically locks the phone and powers off its display more quickly. Apps can detect low power mode is enabled and choose to disable animations and other battery-hungry features, too.
Motion effects and animated wallpapers are also disabled. Background activities and networking are paused to prevent unnecessary power drain in the background. Your iPhone even automatically reduces the performance of its CPU and GPU, which makes it perform a bit slower but saves battery life. Tests have found that this slows iPhones by about 40 percent when Low Power Mode is enabled.
How to Automatically Enable Low Power Mode?
1. Install the Packix Repo
SmartLPM isn’t native to Cydia. It means you’ll first need to install a separate repo in your Cydia app in order to get it. The process is very simple:
- first open Cydia.
- And tap on “Sources” along the bottom of the screen to go to the repository page.
- From there, tap on “Edit” in the upper-right corner, followed by “Add” in the upper-left.
- A URL prompt will appear after tapping on “Add,”
- So you should input repo.packix.com into the empty field.
- Hit “Add Source” once you’re done and give the repo a moment to install.
- Tap “Return to Cydia” once the process completes.
2. Install SmartLPM
- Next, hit the magnifying glass icon on Cydia’s main menu and search for “smartlpm” on the following page.
- Select the tweak once it appears in the results field.
- Once inside the tweak’s Details page, tap on “Modify” in the upper-right corner to proceed with installation.
- Next, tap “Install” on the prompt.
- Then hit “Confirm” on the upper-right corner of the following page.
- SmartLPM will now be downloaded onto your device, so wait a few moments for it complete.
- Then hit “Restart SpringBoard” to respring and wrap up installation.
3. Tweak SmartLPM
Now you’ll need to automate Low Power Mode. Therefore:
- Head to Settings and tap on “SmartLPM” to get the ball rolling.
- Next, tap the “Enable Tweak” toggle to turn the feature on, then make sure “Low Power While Locked” is enabled at a minimum. We also recommend turning on the “Disable Low Power Alert” toggle since you can now automate the options on this notification.
You also have the option to enable Low Power Mode automatically once your battery reaches a certain level. To do this, enable “Auto Low Power Mode,” then adjust the slider to your preferred percentage.
SmartLPM even lets you change the threshold where Low Power Mode will turn back off. For example, if you enable “Low Power While Charging” along with “Disable LPM At Set % (Charging),” and set the latter to 85%, Low Power Mode will automatically turn on when you charge your iPhone and turn off once the battery level reaches 85%.
