Michal Ždanský The battery life of iOS devices has been addressed since the first introduction of the iPhone, and since then there have been many instructions and tricks to increase the battery life, and we have published several of them ourselves. The latest iOS 7 operating system brought a number of new features, such as background updates, which in some cases can drain your device very quickly, especially after updating to iOS 7.1.
A called man named Scotty Loveless recently came up with some interesting insights. Scotty is a former Apple Store employee where he worked as an Apple Genius for two years. On his blog, he mentions that the rapid discharge of an iPhone or iPad is one of the most difficult problems to identify, as it is not easy to discover the cause. He has spent a great deal of time researching this issue as well as hundreds of hours as an Apple Genius solving customer issues. Therefore, we have selected some of the most interesting points from his post that could improve the life of your device.
Over discharge testing
First of all, you need to find out if the phone is really draining excessively or you are just using it excessively. Loveless recommends a simple test. Go to Settings > General > Usage, you will see two times here: Use a Emergency. While the first figure indicates the exact time you used the phone, the standby time is the time since the phone was removed from the charger.
Write down or remember both details. Then turn off the device with the power button for exactly five minutes. Wake up the device again and look at both usage times. Standby should increase by five minutes, while Utilization by one minute (the system rounds the time to the nearest minute). If the usage time increases by more than one minute, you probably really have an over-discharge problem because something is preventing the device from sleeping properly. If this is the case for you, read on.
The mobile client of this social network is perhaps the surprising cause of the fast drain, but as it turns out, this application is demanding more system resources than is healthy. Scotty used the Instruments tool from Xcode for this purpose, which works similar to Activity Monitor for Mac. It turned out that Facebook appeared constantly in the list of running processes, even though it was not currently being used.
Therefore, if constant use of Facebook is not vital for you, it is recommended to turn off background updates (Settings > General > Background Updates) and location services (Settings > Privacy > Location Services). After this move, Scotty's charge level even increased by five percent and he noticed a similar effect on his friends. So if you think Facebook is evil, it's doubly true on the iPhone.
Background updates and location services
It doesn't have to be just Facebook that's draining your energy in the background. Bad implementation of a feature by a developer can cause it to drain just as fast as it does with Facebook. However, this does not mean that you should completely turn off background updates and location services. Especially the first-mentioned function can be very useful, but you need to keep an eye on the application. Not all that support background updates and require location services actually need them, or you don't need those features. So turn off all applications that you don't always need to have up-to-date content when you open them, as well as those that don't need to constantly track your current location.
Do not close applications in the multitasking bar
Many users live under the belief that closing applications in the multitasking bar will prevent them from running in the background and thus save a lot of energy. But the opposite is true. The moment you close an app with the Home button, it's no longer running in the background, iOS freezes it and stores it in memory. Quitting the app completely clears it from RAM, so everything has to be reloaded into memory the next time you launch it. This uninstall and reload process is actually more difficult than leaving the app alone.
iOS is designed to make management as easy as possible from the user's point of view. When the system needs more RAM, it automatically closes the oldest open app, instead of you having to monitor which app is taking up how much memory and manually close them. Of course, there are applications that use background updates, detect location or monitor incoming VoIP calls like Skype. These apps can really drain your battery life and it's worth turning them off. This is especially true for Skype and similar applications. In the case of other applications, closing them will rather damage the endurance.
Push email
Push functionality for emails is useful if you need to know about a new incoming message the second it arrives on the server. However, in reality, this is also a common cause of rapid discharge. In push, the application de facto constantly establishes a connection with the server to ask if any new e-mails have arrived. Power consumption can vary depending on your mail server settings, however, bad settings, especially with Exchange, can cause the device to be in a loop and constantly checking for new messages. This can drain your phone within hours. So, if you can do without push email, set an automatic mail check for example every 30 minutes, you will probably notice a significant improvement in endurance.
More advice
- Turn off unnecessary push notifications – Every time you receive a push notification on the locked screen, the display lights up for a few seconds. With dozens of notifications a day, the phone will be turned on for a few extra minutes unnecessarily, which will of course affect energy consumption. Therefore, turn off all notifications that you don't really need. Ideally start with social games.
- Turn on airplane mode – If you are in an area with poor signal reception, constantly searching for a network is the enemy of battery life. If you're in an area with virtually no reception, or in a building with no signal, turn on airplane mode. In this mode, you can turn on Wi-Fi anyway and at least use data. After all, Wi-Fi is enough to receive iMessages, WhatsApp messages or e-mails.
- Download the backlight – The display is generally the biggest energy guzzler in mobile devices. By lowering the backlight to half, you can still see clearly when you are not in the sun, and at the same time you will significantly increase the duration. In addition, thanks to the control center in iOS 7, setting the backlight is very fast without the need to open the system settings.
Push is misunderstood here.
fetch:
– The iPhone (client) asks the server if new e-mails have arrived
– asks at intervals that can be changed in Settings and the shorter the interval, the more frequent the questions and therefore the faster the battery drains
– the connection between the client and the server is always established only for one fetch
push:
– the server sends information to the iPhone that an e-mail has arrived (that is, the initiation is on the server side)
– there are no intervals, the server will notify immediately after the e-mail has run out
– the connection is permanently established between the server and the client and must be maintained by keep-alive packets. However, they do not ask whether the e-mail has arrived, they only maintain the connection with minimal overhead, after which the server possibly informs about a new e-mail.
This could result in Push saving more battery (when it doesn't have to ask, but is only possibly notified). The problem is, however, when someone receives a large number of e-mails. Since e-mails are not downloaded in batches as Fetch does at certain intervals, but every time an e-mail runs out, the overhead of course increases (establishing a connection, downloading, closing the connection, etc. + the aforementioned lighting of the display, if the user has set). Plus, of course, maintaining the connection with keep-alive packets also has a certain influence.
So it's not black and white.
In addition, not every mail server supports push.
Can it be said that if I receive X emails, it is more advantageous to set the synchronization to 5 minutes? Or somehow like this, so that I can set it accordingly?
If you use the fetch method, which, if you don't have an Apple email (icloud.com, me.com), you most likely use, then the longer the time interval, the better. However, in the settings I only see 15, 30 and 60 minutes or manually, which means that it only syncs when you open the application.
Smartoline..
If I know more about something, I don't know why not share it.
the best solution would be to downgrade to 6. But unfortunately :'(
I can't complain. My iPad 3gen Cell lasts 10-11 hours of use. From FB to WiFi to games over 3G. Exactly the same as on iOS 6
So here are some tips on how to do it from a smart phone, stupid :D isn't it better to buy one?
This reminds me of my neighbor, he bought new wheels for his car, but to make them last, he didn't drive them and when he needed to drive, he took them off :D
(you download the backlight/turn off mail delivery/turn off apps/turn on the airplane) :D
more work than in work with that phone :)
All solutions on how to save energy in a small mobile phone battery. Everything gets smaller/thinner that the phone can't even be controlled properly. What I would give for the phone to be 2 mm thicker with a larger battery capacity.
Yes, I can charge it every day when I come home from work or during work, but I would like more states when I am in the field using GPS, doing sports or camping and I get to the charger once every few days, maybe even longer/week.
Can I ask about shutting down apps. Is there really no need to close them completely? Don't they update in the background? I admit that I also turn them off completely. But I would just try to run it in the background if it would be somehow more convenient.
I have to say that I tried it with the 5S and despite the fact that I turned everything off and set airplane mode, my usage jumped by 5 minutes after 5 minutes. So have I set something wrong somewhere or do I have a defective battery??
I have never actively used the Facebook app on the iP5s. I had data and location disabled for it, it wouldn't run at all during the day. Sometimes I looked at the statuses via wifi in the evening so that I didn't have to go to the PC right away. I completely uninstalled it yesterday after reading the article.
Result?
After three hours of use today I still had 65% battery. Instead of 40% yesterday. At the same time, I always have Wi-Fi on, emails are checked every hour, I access Twitter, check photo banks, sms messages and FB messenger, make calls, sometimes listen to music.
It's not about making your smartphone dumb. The iPhone is not bad in this regard, charging every day (even two for me - I hope to return to the original values now) is a tax for a quality display and a complete office in your pocket, which I think is fine. But as you can see, even one application will drain the battery. So I would be a little cautious here.
So I deliberately turned off background app updates, left the phone on the table overnight, and the usage time = standby anyway. So I don't see what it does...
The battery is very drained by the system services that use location, which have been activated since system 7 - In Settings - Privacy - Location services - at the very bottom System services and I have turned off everything except compass calibration, the other things are quite useless, but that can be chosen by everyone according to what needs
Hello, I want to ask how is it possible that after updating to 7.1.1 my phone shows the same standby time as usage, which also affects the battery life, I could be active for a maximum of 2 hours, I woke up in the morning and I can't be surprised, it happened Does it happen to anyone, or do you know what to do with it? Thank you
