Tips: How to Improve your iPhone Battery Life and Performance

iLawyerJan 6, 20184 0375 votes +5 rating

The revelation would appear to lend weight to a popular conspiracy, though the tech giant says it throttles performance on the mobile phones as a precautionary measure. Apple has admitted to intentionally slowing down iPhones as they get older, without notifying customers. The revelation would appear to lend weight to a popular conspiracy theory about the mobile phone. However, the tech giant claims the move is not designed to encourage customers to upgrade to newer iPhone models.

How to improve your iPhone battery life and performanceRather, Apple says it throttles iPhone performance as a precautionary measure. If it did not, the company claims, older iPhones would keep shutting down unexpectedly or break earlier than they should.

“Last year we released a feature for iPhone 6, iPhone 6s and iPhone SE to smooth out the instantaneous peaks only when needed to prevent the device from unexpectedly shutting down during these conditions,” Apple told Reuters. “We’ve now extended that feature to iPhone 7 with iOS 11.2, and plan to add support for other products in the future.”

The issue comes from the iPhone’s battery, rather than its processor.

So, iPhone battery life – Tips to make your Apple handset last longer:

1. Limit notifications

Notifications are incredibly useful, but they also drain battery life and not all of them are actually necessary. Switching off notifications for certain apps can help your phone’s stamina. On Android, head into Settings, hit Apps and select those you don’t need to be notified by. On iOS, go to Settings and then Notifications.

2. Disable auto-sync

Certain apps, such as email and social networks, constantly run in the background even when you’re not using them. This is so you see updated information and updates when you do open the apps, but the benefits can be offset by the amount of battery life auto-sync can eat up. On Android, you can turn off auto-sync by going to Settings, Accounts and hitting the menu button. On iOS, go to Settings, General and Background App Refresh.

However, since auto-sync is genuinely useful, we’d recommend disabling it when you know you’re going to be running low on battery life, rather than switching it off all the time.

iPhone slow? Try replacing your battery! Reddit’s topic opinion:

It works! I just now replaced my battery ($50). The benchmarks report the expected numbers (1465 single, 2638 multi core) and the CPU frequency is now 1400MHz. When they took out the battery, half of it was soft! The tech said my battery was really used up.

I have a 6 Plus. The battery has 706 cycles and 74.3% battery capacity left now (measured with coconutBattery). With Geekbench 4, I’m getting 1023 single-core, 1799 multi-core. This is run with battery at 54%. CPUDasherX says the cpu frequency is at 839MHz, but it should be a max of 1.4GHz. I don’t know if this is the current speed (which sounds right) or the max speed, which is clearly too low.

My 6+ has been glacially slow since iOS 11. In addition, my phone will die in cold weather. It may have 50% battery and then suddenly it will report 5% battery left. I’m frustrated that I am forced to buy a new phone even though this one was just fine on iOS 10. I’m going to pop in a new battery and hope it saves this phone.

3. Switch off location services

GPS is a huge drain on your phone’s battery, as more and more apps use your location data to work out where you are, and shape your experience according to that information. Unless you’re using a Maps app, you can get by without it. To turn off GPS on Android, go to Settings and Location. On iOS, go to Settings, Privacy and Location Services.

4. Lower brightness

Your phone’s display is responsible for the biggest impact on your battery life, but it’s easy to limit how much energy it uses up. Auto-brightness is convenient, but often sets the screen brightness to a much higher level than it needs to be. Turning auto-brightness off, setting your display’s brightness to a lower level and adjusting it when you need to is much more sensible.

5. Uninstall apps you don’t need

Some apps drain more battery life than others, and it’s worth working out which ones you can do without. Facebook, for instance, is known to have a big impact on your phone’s battery, and you can eliminate this by deleting the app and using the social network in your web browser instead.

On Android and iOS, you can see the apps and processes that are affecting your battery by going to Settings and Battery. From there, work out what you can delete or replace with a less-demanding alternative.

iPhone slow? Try replacing your battery! Reddit’s topic opinion:

I have a 6s Plus from launch day. Apple never acknowledged this problem for the Plus models, but I have had the shutdown at random percentage issues many times. I tried Geekbench and got 2187/3689. It’s not massively less but it is worth taking note considering the normal scores for a 6s Plus are 2455/4193.

The phone isn’t on battery saving mode and it’s not overheating so I see no reason why it shouldn’t attain peak performance scores other than the battery which has dropped from 60% down to 38% in a matter of minutes. I believe that some 6s Plus batteries have the same fault as the 6s, but I’ve had no luck trying to get Apple to replace it. I may run Geekbench again at 100% battery whilst plugged in and see if I get a better result.

6. Cut your assistant off

Virtual assistants are becoming increasingly capable, and therefore increasingly important in tech companies’ eyes. Not all consumers share the enthusiasm of Google and Apple though, and rarely – if ever – use Google Assistant and Siri. Whether you use them or not, by default the two assistants are always listening out for their trigger words, and this uses up battery life.

On Android, you can switch this off by going to Settings, Google, Search, Voice and “Ok Google” detection. On iOS, go to Settings, Siri and Allow “Hey Siri”.

7. Stop vibrating

Vibrate is a great middle-ground between a potentially disruptive ringtone and total, uncertain silence, but it also uses up the most battery life of the three options. You can go a step further by also disabling tap feedback, which can be reassuring, but is ultimately unnecessary.

8. Turn off connections

If you’re connected to a Wi-Fi network, switch your mobile data off, and vice versa. Similarly, remember to turn off Bluetooth and NFC when you’re not using them.

9. Airplane mode

Airplane mode isn’t just for when you’re on an aeroplane. If you know you’re not going to have or won’t need signal or a Wi-Fi connection for a good amount of time, it’s worth enabling Airplane mode. Otherwise, your phone will use up battery life by pointlessly trying to connect to a network.

iPhone slow? Try replacing your battery! Reddit’s topic opinion:

Also, if you’ve never opened up an iPhone before, I’d highly suggest watching a lot of videos on the process before deciding to do this yourself. While the battery replacement is one of the easier repairs you can do on the 4 and up, it’s still very, very easy to damage your display assembly or rip a flex cable if you go into it with little knowledge of how the internal hardware is set up. The battery replacement on the 4 and 4s are hands-down the simplest, and only require you to remove the back plate (2 screws) and one or two screws to disengage the battery connection; nothing else has to be removed or touched. The 5 and up went back to making the display assembly the first component removed (like the original models), and they added a lot more to it that makes it much more difficult without the right tools.

If you don’t have the right tools (they’re not terribly expensive), it’s even easier to damage things. And self-repair absolutely voids your warranty, including AppleCare, so keep these things in mind. If you do the repair correctly and cleanly (and with actual OEM parts), Apple employees likely won’t notice if you have to do a warranty replacement down the road, but using non-OEM parts or damaging the inside of the phone in any way will void your warranty.

Also, be smart about where you purchase the battery, as there are a lot of sketchy "re-sellers" out there who sell counterfeit OEM products, and buying a fake battery (or one that’s been previously damaged) can easily lead to damaging the device (best case scenario) or having the thing explode in your pocket.

If you don’t feel comfortable doing it yourself, go to an Apple Store or an Authorized Apple Retailer/Service Provider, as this won’t void your warranty, and you can be very certain you’re getting OEM parts installed by techs who know what they’re doing.
