  • Level 5  
    Hello. In August, I bought an iPhone 7, it worked ok until the beginning of December, then suddenly began to eat something very quickly. From the full charge of the battery to the discharge of the phone goes only 8 - 9 hours doing nothing on the phone where previously using the phone held the battery for 2 days. I reported this fact to the phone seller and sent it back to the site. They kept the phone there for two weeks and sent it back and it is still the same they did nothing. Could any of you know what this might be for a problem that the battery eats so quickly? And can they replace the model after the service?
    greetings

    You go into the settings, battery tab and there shows you what consumes the most energy.

    Or resetting (restoring factory settings), and then reinstalling everything. Under no circumstances restore from the iCloud archive, because you will also restore the error that causes the battery to "eat".

    So, should I set up a new Ipple account?

    It is known that after the introduction of the latest iOS 11 began to occur with the rapid use of batteries. Now Apple also admitted to this quote:

    Tim Cook claims that this way it ensures smooth operation of iPhones. The problem is that with very resource-consuming tasks, the processor's power consumption increases momentarily to high values. Older batteries are not able to cope with such rapid increases in energy demand, which may result in the iPhone turning off faster.

    Along with the iOS 11.2 system, this solution also went to the iPhone 7. In the future it also has to hit newer devices.

    Apple concealed the whole process. Now officially admitted to it.

    What are your home versions of the software?

    I have iOS 11.2.1 only after updating it worked ok with two days battery kept. Only recently has something happened that keeps you less. I read a bit and somebody wrote that the A2 layout could be damaged.

    You talk about the charging system, I put more on this soft, but if you have a phone for warranty, you can always advertise it.

    Well just 4 days ago he returned from the complaint and the problem is still the same nothing they did not do.
  • Level 15  
    If he returned from the complaint, he probably eliminated the power problem, upload a clean soft lower than iOS 11 and see if the problem will continue to occur. Kuzyn He had the same problem after uploading the iOS11 version and had to go down to the lower version, take a copy earlier. The problem has disappeared but as I wrote, you will not avoid it in the newest versions what Apple itself has confirmed and already in the US is preparing a lawsuit against Apple users because the company slowed down operation of older versions of the iPhone due to fast battery consumption.
    Read about it on the internet is loud about it.
    It is possible that you have also uploaded a program that pulls your batteries - let's hope it is in good condition - because there were also examples of users in the US that after replacing the new phone Iphone 7 significantly improved its functioning.


    What is your current soft download after the complaint - should unfortunately be the latest? And whether the complaint was with the manufacturer or advertised in some ordinary service?

    A friend knows that he is calling somewhere, but he does not know where.
    This is about lowering the clock speed in the case of a battery that has already passed.

    The author still did not look into the "BATERIA" menu and did not write what gets him the most energy.

    I will refresh the topic.
    The author, regardless of the result, should write how the matter ended / solved .. People who can not finish the topic are terribly annoying.
    Currently, I have the same problem, the problem occurred on how the phone spent several hours in the cold, then the battery from 30% fell to 1% and so lasted the next few hours until I got home and connected. Since then (2 days), the battery is discharging very quickly, and it is charging very quickly, with 1% it jumps to 60% within 20 minutes.
    After the indications of the "battery" application, one installed app has high consumption, I will check what will happen and let me know.

    like a few hours in the cold

    A colleague will praise in what "cold". Are we talking about negative temperatures? In your case, it looks like a battery damage and no problem is solved. If the battery charges 60% in 20 minutes it is definitely for exchange.

    You're right, I'm sorry for not full information.
    The temperature at the level of 3 degrees, the time lying in such a temperature about 4 hours.
    The following activities have been carried out;
    - turning off the time in front of the screen
    - switching off - switching on the device
    - uninstalling the application installed upon arrival, which in; settings -> battery, indicated the highest consumption

    Currently, after these treatments the power drop is a bit smaller, but I will know only in a few hours if the problem has decreased.
    In fact, I have a battery at 80% of consumption

    I will only ask if there is a sudden need to replace the battery? Earlier, the phone worked without any problems.

    After leaving the phone in such a low temperature for such a long period it is possible. First, however, I would dismantle it and check if it was not damp (condensation). It may be that the water just condenses and there is more than just a battery to replace. If there are no traces (which does not mean that you can exclude "flooding"), replace the battery.

    This is not extreme temperature. The temperature is even lower in the pocket of the jacket, the backpack or the winter bag. And how many times has my phone stayed overnight in the car and somehow the battery survived.

    A wild-boar colleague did not give the model, but the 7th is waterproof.

    What is waterproof for condensation?

    You were just lucky. The issue is still that, as he wrote @ wild-boar

    Yes gentlemen, this is the iPhone 7
    Initially, I will replace the battery as soon as the adhesive strips reach my battery, I will have an original 90% from a survivor from a friend (until the power dropped to 80% the equipment worked perfectly) and somehow I have more confidence in replacements. After the exchange I will check further.
    Immediately I ask for info on checking the moisture he mentioned @ gathor10 , after a damp paper, I can check it out somehow?
    And so I will ask, how to remove the "service" from the batteries after the exchange? A friend once mentioned in and; settings-> battery-> battery condition, appeared to him with information (despite the 95% status) "service"

    Apple exchanges batteries with a one-year warranty. I exchanged in my i7 and i +. ? 25 per item in the Apple salon. Time of waiting.

    Water tightness for condensation has a lot. If something is watertight, there is nothing to condense inside.

    It would go on to argue, but it would be necessary to write a very extensive report on this subject.

    If you have a microscope, it's the easiest way to check if there's patches on components, etc. If it's not just "papers"
  • Level 5  
    ok, if it really will be a battery is not a big problem and in the end I will go to the website, in PL something like PLN 150 costs exchange,
    I do not have a microscope, and the paper under the tray shows white color

    edit.
    battery mentioned in 96% and so far the indication is correct, but the best thing is that despite the decrease to the theoretical 1% it actually had more and the power drop was normal. After charging, I used the phone until I jumped again 1% and after that I left the phone unused, I looked at him for a long time and so he watched two days and after putting the battery to another device it turned out that it was still 21% before the phone would turn off.
