Sometimes when I’m in a rush to go somewhere, I’ll plug my iPhone into a power source or set it on my Qi wireless charging stand while getting ready to juice it up as much as I can beforehand. But I’ll be the first to admit that waiting for the battery percentage to rise while charging can be a daunting process, especially since iOS doesn’t provide any sort of ETA for a full charge.
Here to change that is a new free jailbreak tweak called Remaining Charge Time by iOS developer Teun Strik, which adds a charging remainder to the bottom of the Lock screen whenever your handset is charging to let you know (approximately) how long you’ll need to wait before it’s done.
As depicted in the screenshot example above, Remaining Charge Time puts the newfangled charging remainder in place of the Lock screen‘s typical ‘press home to unlock or ‘swipe up to unlock’ text. The number gradually updates as the device charges.
You might notice a ludicrously-inaccurate charging estimate when you first plug your handset into a power source. If this happens, then don’t panic; it takes a few moments for the tweak’s charging algorithm to figure itself out because it’s actively collecting information about the charging speed of the power source and comparing it to the current battery capacity, among other things, to achieve output.
In our testing, we found that Remaining Charge Time took about five minutes for the charging estimate to normalize to our expectations. Once it did, it appeared to be somewhat accurate in predicting how soon our handset would approach 100% battery capacity, give or take a few minutes.
I’ve always wanted a jailbreak tweak like this, and so I’m excited to say that I’m impressed with how well it works and that I would recommend it to my friends and fellow jailbreakers. The tweak doesn’t even come with any options to configure – just install it and you’re good to go.
If you’re interested in trying Remaining Charge Time for yourself, then you can download it for free from Cydia’s BigBoss repository. The tweak supports all jailbroken iOS 11 and 12 devices.
