Why is the iPhone 5 battery draining fast?

Question

iPhone

For two days I notice that the phone after charging seems to discharge faster, 1.5 times faster. Charging continues as usual. Time has not increased or decreased. But this is half the trouble. On airplane mode, a phone with 100% can sit down to 0 overnight. In this case, the battery does not heat up. Is my battery dead or is it a software problem?

Answer 1

Most likely, background services, such as geolocation or background updates, can be cut off in the settings. In general, this is a widespread problem for the iPhone 5, after a year and a half, the battery begins to actively die, and then only a replacement will solve the problem

You can then restart your phone if you haven't done so already. Perhaps some process is hanging and constantly loading the processor.
After all this, you can do a full reset of the device to factory settings in order to remove all installed software, which can also be constantly launched after rebooting the device and load the processor.
And there remains an option with problems in the firmware using the battery. Then you should read on the Internet on your firmware and improper use of the battery. If so, then flashing the phone.
Well, do not exclude that the battery itself could lose capacity.
