The cell phone batteries drains easily before a full 8-hour workday is complete, which means that you have to charge it every few hours. Here are top 12 tips to help you conserve the battery life of your iPhone 4S for long hours. The iPhone 4S has an ambient light sensor that adjusts the screens brightness according to the lighting conditions of your surroundings. This saves battery by lowering the brightness in brighter places.

12 Tips to make Your iPhone 4S Battery Last Longer

If you keep your Wi-Fi on all the time it drains away the battery very fast because the phone constantly updates data from different installed applications. Bluetooth is a major battery drainer.

So switch off Bluetooth and Wi-Fi when they are not in use. For better broadband packages log on to Broadband Expert.

This helps you in obtaining directions to any place you want. Smart as it may be, it exhausts the battery pretty fast.

Be sure to turn off the location service when you do not intend to use it. Activating the e-mail push service means that your iPhone 4S is connecting to your mobile network after short intervals to update your e-mail accounts. Instead of activating push e-mail and notification, you can choose to update it manually when you need to check for updates. This interval will in any case be longer than the short interval of push service. The EQ enhances the sound output by adjusting the bass and treble, but drains the battery much faster than just listening to songs does.

Tips for improving your iPhone 4S & iOS 5 battery life … battery-gate?

For longer battery life try listening to songs without turning on the EQ. Setting the auto-lock timer to as less time as possible results in saving a lot of battery life in the long run because the phone sleeps earlier. Background application running all the time are the biggest battery drain for your iPhone 4S, so kill them. For this performance test, I did a fresh install of iOS on each device, signed it into a test iCloud account, and let the phones sit for a while to complete any indexing or other behind-the-scenes tasks.

I then opened each app three times and averaged the results. In the past, this has been a fairly reliable indicator of how each phone will actually feel in day-to-day use.

If opening an app and waiting for it to load on a fresh iOS install feels slow, that usually means that the rest of the phone including waiting for the keyboard to pop up, waiting for pages to load, and other tasks will feel slow too, especially as you download more stuff and connect more accounts. In general, iOS 13 running on these phones is almost imperceptibly slower than the same phones running iOS 12, though in many cases performance breaks just about even.

If some of the percentages seem high, it's because the times are so low that any difference at all looks like a bigger deal than it is—in practice, you don't really feel any of these differences. The only outlier is the TV app, which did take significantly longer to fully load in iOS 13 than in iOS 12, but we're just talking about a small delay in an app that people aren't going to use as often as Messages or Mail. It should be no surprise that the A9 can run iOS 13 well.

Several apps open in just over half a second, which is essentially instantaneous. These are heavier apps that need to load more things before they start responding to user input. The 6S I used to test iOS 13 ran the operating system perfectly well, but even with a brand-new battery directly from Apple, I could never make it through a whole day without needing to recharge.

After almost a year with my iPhone XR , which can last a full day and a sleepless-infant-filled night before it needs to be plugged in, the 6S feels even worse. For the SE, which has always fared better in the battery department , the screen size is more pressing.

For people still hanging on to the SE, the small size and the small screen might be the entire point, but there are more areas creeping into the operating system where Apple is just shrinking things down to fit the display, rather than keeping text, buttons, and images the same absolute size as they are on larger phones and just fitting less stuff onscreen at once. Take the widgets that appear alongside the context menus when you long-press some icons on your home screen as an example.

When these were originally designed, they were intended for the 4. But now that they're accessible on a smaller screen, rather than keeping the contents of the widget the same size and tweaking the size of the box, the box and all of the stuff inside it are just smaller, harder-to-read versions of what you'll see on larger phones.

I do fully appreciate the plight of the small-handed and small-pocketed who have had to watch phone sizes steadily and inexorably increase over the last decade. I also don't think that the areas where the SE's size affects its utility are things that most people are really going to be bothered by.
